Abstract

PROBLEM TO BE SOLVED: To provide a wall mounting fixture capable of preventing a mounting fixture from being removed from a wall or preventing attitude of the mounting fixture from being tilted with respect to the wall when force is applied to the mounting fixture to come off the wall and so on, by enforcing engagement between the wall and a needle member plunged into the wall.SOLUTION: The wall mounting fixture includes a needle member 11, and a head member 12 with the needle member 11 attached thereto, and as the needle member 11 is plunged into a wall W, the head member 12 is fixed to the wall W via the needle member 11. Elongated plate-like pins 14, 15 provided to the needle member 11 and having a sharp front end are formed with wedge parts 23, 24 which become resistive in a removing direction of the needle member 11 from the wall W. When the needle member 11 is plunged into the wall W, resistance for the wedge parts 23, 24 from the wall against the plunging is not large, facilitating mounting by plunging into the wall W, and the wedge parts 23, 24 make it hard to remove the needle member 11 from the wall W in the plunged state.

Description

  The present invention relates to a wall fitting used for hanging an article such as furniture such as a shelf or a box on a wall of a structure such as a house.

  Conventionally, in general houses, shelves, storage cases, decorations, and articles such as mirrors and frames are attached to walls made of wall materials such as wood such as plasterboard, concrete, and plywood. ing. As a structure for attaching the article to the wall, there is a structure in which a pin is fixed to a wall material and the article is hung on the fixed pin. Since the article is only latched on the pin, there are no installation-related tools or devices around the article, so that the appearance is good. It is also easy to remove the article from the wall by removing the latch on the pin.

  When an article is hung on a wall, the load that the wall can withstand depends on the type of the wall material. Accordingly, in consideration of the type of wall in addition to the weight of the article, the form and number of pins to be used are selected.

  As an example of a mounting tool to be mounted on a wall surface, there is one disclosed in Patent Document 1. The mounting tool includes a pin head and a pin needle portion extending from the pin head, and an engagement member that engages with the pin so as to embrace the pin head is attached to an ornament to be attached to the wall. It is possible to attach a decorative object to the wall by engaging the engaging member with the thumbtack-like pin for the thumbtack-like pin attached to the wall by piercing the pin needle part into the wall. I have to.

  The pin can be in the form of a needle that is pierced into the wall by piercing if the ornament to be attached is light. However, if the ornament is heavy, a nail or a threaded screw nail is used instead of the needle, and the pin can be moved by driving the nail into the wall or screwing the screw nail into the wall. It is done to attach to the wall.

  When a large force is applied in the pulling direction to a mounting tool having a pin head and a pin needle extending from the pin head, an article having a weight that is greater than expected is suspended or supported, or a wall If the wall does not have enough force to hold the pin needle due to the state of engagement with the pin needle that has been stabbed, the wearer may be pulled out of the wall by the pulling force applied to the pin head. Depending on the weight of the article, a moment to pull out the pin needle portion stabbed in the wall from the wall acts, and the wearing tool partially pulls out from the wall, or the posture of the wearing tool with respect to the wall is inclined, or There is a risk that the wearing tool may be completely pulled out of the wall and detached.

  In a stab pin for a wall mounting tool that pierces a hard wall such as a concrete wall, the resistance force of the wall is large, and it is necessary to drive the stab pin with a large force to overcome it. However, it is difficult to continue piercing the pin with such a large force while maintaining a straight posture with respect to the hard wall. That is, the piercing pin is likely to be deformed from the beginning of driving or during the driving, or the posture of the piercing pin is likely to change. If the piercing pin itself is deformed or its posture is deformed, the piercing pin cannot be attached in a correct posture with respect to the wall, and the piercing pin is easily detached from the wall.

Japanese Patent Laid-Open No. 10-151061

  Therefore, an attachment tool including a needle member that is pierced into a wall and a head member to which a root portion of the needle member is fixed, and an engagement tool that is engaged with an article that is latched on the wall is the attachment tool. However, there is a problem to be solved in that the shape and structure of the needle member are devised to strengthen the engagement between the wall and the needle member pierced by the wall.

  An object of the present invention is to solve the above-described problem, and not only to a relatively soft wall but also to a relatively hard wall such as concrete, a wall and a needle member that is inserted into the wall, When the force that pulls out of the wall is applied to the mounting tool or when the weight of the article is applied to the pin head, the mounting tool is pulled out of the wall or the wall of the mounting tool. It is providing the wall mounting tool which can prevent that the attitude | position with respect to is inclined.

  In order to solve the above-described problems and achieve the above object, a wall mounting tool according to the present invention includes a needle member and a head member to which the needle member is assembled, and the needle member is pierced into the wall. The head member is a wall mounting tool that is fixed to the wall, and the needle member includes an elongated plate-shaped pin having at least one pointed tip, and the needle pin includes the needle member. Is formed with a wedge portion which becomes a resistance in a direction of coming out from the wall.

  According to this wall mounting tool, the needle member is different from a thin pin with a circular cross section, and at least one pin is an elongated plate-like pin with a sharp tip, so the wall is a hard wall such as concrete. Even if it exists, the piercing force received when the pin is pierced into the wall can be concentrated and pierced easily at the tip portion. That is, since the pin is a cross-section of a thin plate, unlike a pin having a large diameter, which is driven into a concrete wall, the degree of wall deformation and push-out during piercing is small, and piercing is easy. In addition, damage to the wall can be reduced. Further, the plate-like pin is formed with a wedge portion that becomes a resistance in the direction in which the needle member comes out from the wall. Therefore, when the needle member is pierced into the wall, the wedge portion has a large resistance against the piercing. However, it is easy to mount by piercing the wall, and in the pierced state, the wedge portion gives a great resistance to the needle member from slipping out of the wall and makes it difficult to slip out. Therefore, after the piercing, the wall sandwiches the plate pin from both sides, and the wall mounting tool is firmly held against the wall. The needle member may be fixed to the head member in advance, and can be fixed to the head member when the head member is penetrated later.

  In this wall mounting tool, the wedge portion is a cut-and-raised portion in an aspect in which a cut portion formed in the plate-shaped pin is inclined toward a rear portion in the piercing direction with respect to the plate surface of the plate-shaped pin. It can be formed as a raised piece. The wedge portion is not formed as a separate part but is formed as a cut-and-raised piece raised from the plate surface of the plate-shaped pin itself, so that it is formed simply and at low cost by metal processing such as cutting the plate-shaped pin or pressing. be able to. Further, when the wedge portion is pierced into the wall, the cut and raised piece is deformed so as to be bent back by the action from the wall into the space generated in the plate-like pin by the cut and raised, so the piercing resistance to the wall is small. Become. On the other hand, after piercing the wall, if a force in the pull-out direction acts on the wall mounting tool, the cut-and-raised piece acts in a direction where it is cut and raised, that is, the wedge part bites into the wall. It is difficult to pull out the wall from the wall, and the wall mounting tool can maintain its stable posture without tilting or prevent the wall mounting tool from completely slipping out.

In the wall mounting tool, the cut and raised piece is located at a side portion of the plate pin or a region in the center in the width direction of the plate pin. In addition, it may be a cut and raised piece formed independently.
Further, in this wall mounting tool, the cut and raised pieces are a plurality of cut and raised pieces formed side by side in the piercing direction in the region of the side edge of the plate pin or the region in the center in the width direction of the plate pin. It can be assumed that In this case, for the plurality of cut and raised pieces, at least one cut and raised piece cut and raised with respect to one plate surface of the plate-like pin and the other plate surface of the plate-like pin. And at least one cut and raised piece cut and raised.
The formation position and the number of the cut and raised pieces in the plate-like pin can be appropriately selected according to the material of the wall, the performance of fixing the wall to the wall mounting tool, and the like.

  In this wall mounting tool, the cut and raised pieces can be formed in the same width shape, gradually wider shape, or gradually narrower shape toward the rear in the piercing direction of the plate pin.

  In this wall mounting tool, the plate-like pins having pointed tip portions of the needle member have a common root portion and are formed in a common plane so as to be arranged in parallel. It can be said that it is a pin. By making the plate-shaped pins of the needle member into at least two parallel pins formed so as to be arranged in a common plane, the needle member is manufactured in large quantities by sheet metal processing such as punching from a single plate material. In the state of being pierced into the wall, since a plurality of plate-like pins are pierced into the wall, the wall of the needle member is fixed to the wall of the needle member with a large fixing force. The attachment to can be ensured.

  In the wall mounting tool, the head member holds the needle member to be assembled, and guides the movement of the needle member when the needle member penetrates the head member from the holding state and is stabbed into the wall. A holding guide groove can be formed. The needle member can be fixed to the head member when penetrating the head member by driving into the head member or the like. When the needle member is assembled to the head member, the needle member can be held in the holding guide groove, and in this state, it is possible to prepare for piercing the wall or to distribute it as a product. Further, when the needle member is passed through the head member and pierced into the wall, the needle member is guided and moved by the holding guide groove, so that the needle member can pierce the wall in a stable state without causing buckling. A concave groove can be formed in the holding guide groove according to the position and height at which the wedge portion is provided so that the wedge portion can easily pass when the needle member passes.

  In this wall mounting tool, the head member can be formed of resin, and the needle member can be fixed to the head member by insert molding. That is, when the head member is formed of resin, the needle member is insert-molded, whereby the needle member can be fixed to the head member in advance, and the wall fitting can be manufactured efficiently. In the case of insert molding, a resin inflow hole is formed in the needle member, and the needle member can be firmly and securely fixed by solidifying the resin flowing in at the time of insert molding.

  In this wall mounting tool, a cap that covers the needle member can be mounted on the head member with the needle member penetrating. By attaching the cap to the head member, it is possible to eliminate the needle member from appearing on the front surface, and the appearance of the wall mounting tool is improved. In addition, the wall hanging article can be engaged with the cap.

  Further, in this wall mounting tool, when the wall hanging article is actually hung on the wall, the wall hanging article can be directly engaged with the head member. Further, the wall-mounted article can be indirectly engaged through an engaging tool that is locked to the head member.

  The wall mounting tool according to the present invention is a wall mounting tool that includes a needle member and a head member to which the needle member is assembled, and the head member is fixed to the wall when the needle member is pierced into the wall. The needle member is provided with an elongated plate-like pin having at least one pointed tip, and the plate-like pin has a wedge portion that resists in a direction in which the needle member is pulled out from the wall. Is formed. Therefore, the needle member is different from a thin pin having a circular cross section, and at least one pin is an elongated plate-like pin having a pointed tip portion. Therefore, even if the wall is a hard wall such as concrete, the needle When the member is pierced into the wall, the piercing force received by the pin can be easily pierced into the wall by concentrating on the tip portion. That is, since the pin has a thin cross-section, unlike a pin having a large diameter, which is driven into the wall, the deformation and push-out of the wall at the time of driving are reduced, and damage to the wall is reduced. And in a fixed state, a plate-shaped pin will be clamped from a wall on both sides of the plate surface, and the fixing force to the wall of a plate-shaped pin can be heightened.

  In this way, the needle member can be pierced accurately and reliably even on a relatively hard wall such as concrete, and the head member can be fixed to the wall via the needle member and fixed to the wall. It is possible to provide a wall mounting tool for mounting an article on a wall directly by a head member or indirectly through an engaging tool. The plate-like pin is formed with a wedge portion that becomes a resistance in the direction in which the needle member comes out of the wall. Therefore, when the needle member is pierced into the wall, the wedge portion pierces the wall of the needle member. The resistance to is small and does not hinder the needle member from being pierced into the wall. However, after the wall mounting tool is mounted on the wall, when the force that tries to pull out from the wall acts on the needle member, the wedge part bites into the wall around the needle member, resulting in a large resistance force against the needle member pulling out. The needle member can be prevented from easily coming out of the wall.

  Hereinafter, an embodiment of a wall fitting according to the present invention will be described with reference to the accompanying drawings.

  FIGS. 1 to 4 are views showing Embodiment 1 of a wall mounting tool according to the present invention, in which (a) of FIG. 1 is a plan view of the wall mounting tool, and (b) is a wall mounting tool shown in (a). AA sectional drawing, (c) is a bottom view, (d) is a side view. 2A and 2B are diagrams showing a needle member used in the wall mounting tool shown in FIG. 1, wherein FIG. 2A is a front view and FIG. 2B is a side view. 3 is a view showing a head member of the wall mounting tool shown in FIG. 1, wherein (a) is a top view, (b) is a cross-sectional view of the head member shown in FIG. Is a bottom view. 4 is a view showing a cap used in the wall mounting tool shown in FIG. 1. FIG. 4A is a top view, FIG. 4B is a cross-sectional view of the cap shown in FIG. It is a bottom view.

  A wall mounting tool 10 according to the first embodiment of the present invention shown in FIG. 1 includes a needle member 11 made of metal such as stainless steel, a resin head member 12 through which the needle member 11 passes, and a head member 12 covered. The cap 13 is provided. The wall mounting tool 10 is capable of locking an engaging tool (not shown) engaged with a wall-hanging article to the head member 12 in a state where the needle member 11 is pierced into the wall, or the engaging tool is mounted on the wall. It can be fixed to.

  As shown in FIG. 2, the needle member 11 includes two elongated thin plate-like plate pins 14 and 15 and a root portion 16 that is continuous with and common to the plate-like pins 14 and 15. ing. The two plate-like pins 14 and 15 sandwich a gap 20 from the root portion 16 to the needle width of the plate-like pins 14 and 15 (the illustrated one is slightly narrower than the needle width, but is not limited thereto). And extend in the same direction in parallel to each other and have the same height. The two plate-like pins 14 and 15 are arranged so as to exist in a common plane including the root portion 16. In addition, as shown in FIG. 2, the plate-shaped pins 14 and 15 are made difficult to be broken even when pierced or driven by forming an R portion at the base of the root portion 16.

  The leading portions 21 and 22 of the plate pins 14 and 15 are respectively formed in the same triangular mountain shape, and the plate pin 15 is formed in a tapered triangular mountain taper shape not only in the width direction but also in the thickness direction. Has been. The tapered head portions 21 and 22 make it easy to pierce when the plate-like pins 14 and 15 are pierced into the wall. That is, since the plate-like pins 14 and 15 are long and thin plate-like pins whose tip portions are pointed in the width direction and the thickness direction, the piercing force acting when piercing the wall is the force of the plate-like pins 14 and 15. Even if the wall is a hard wall such as concrete concentrated on the tapered tip portions 21 and 22, the wall can be easily pierced by the wedge action. Since the cross-section of the plate-like pins 14 and 15 is a thin cross-section, the degree of deformation and push-out of the concrete wall at the time of piercing is small, and damage to the concrete wall can be reduced.

  The needle member 11 has a plate-like shape having a base portion corresponding to the root portion 16 in the center and two plate-like pins 14 and 15 extending continuously from the base portion by punching from a single metal plate, preferably a stainless steel plate. Made as a pin. The needle member 11 has a uniform thickness including the plate-like pins 14 and 15 excluding the tip portions 21 and 22 from the root portion 16. However, at the time of punching or after punching, the thickness of only the leading portions 21 and 22 is gradually reduced toward the tip by pressing. From the root portion 16 to the tip portions 21 and 22 of the plate-like pins 14 and 15, the plate thickness can be formed so as to gradually decrease toward the tip. The plate-shaped pin of this structure is easy to pierce the wall because the thickness of the tip portions 21 and 22 is the thinnest, and from not only a concrete wall but also a relatively soft wall material such as a gypsum board. It is also suitable for piercing the wall.

  As shown in detail in FIG. 2, the plate-like pins 14, 15 have two wedge portions 23, 24 in the regions of the outer side edges of the plate-like pins 14, 15. Are formed in a symmetrical position with respect to the longitudinal center line of the needle member 11. The wedge portions 23 and 24 are cut by raising the plate-like pins 14 and 15 so as to be inclined from the plate surfaces 14a and 15a on one side of the plate-like pins 14 and 15 toward the rear in the piercing direction. It is formed as a raising piece. In this example, the plate-like pins 14 and 15 are formed in a wider shape gradually toward the rear in the piercing direction. The wedge portions 23 and 24 can be formed by simple metal processing that is performed at the time of manufacturing the needle member 11. Further, the wedge portions 23 and 24 are cut and raised in the same manner (shape, inclination accuracy, etc.) except that the formation positions are different.

  Since the wedge portions 23 and 24 are inclined toward the rear in the piercing direction, when the needle member 11 is pierced, the wedge portions 23 and 24 are deformed so that the inclination is lowered, and thus the resistance to the wall is large. However, when the needle member 11 in a state of being pierced into the wall is to be extracted from the wall, it becomes a great resistance against such extraction from the wall. Holes 16 a and 16 a for material removal are formed in the root portion 16 of the needle member 11. The holes 16a and 16a are also used when the needle member 11 is insert-molded with respect to the head member 12 (the resin as the material of the head member 12 flows in to strengthen the connection with the head member 12). Although it is provided, it is not always necessary to provide it only for driving without insert molding unless it is a material saving purpose.

  As shown in FIGS. 1 and 3, the head member 12 is manufactured in advance, and is formed in a stepped columnar block shape with resin as a whole. The head member 12 includes a block-shaped main body portion 25 and a head end portion 26 which is integrated on the proximal side of the main body portion 25 and whose outer diameter is enlarged once. The head member 12 is formed with a slit 27 extending in the central position, that is, in the diameter direction of the cylinder and penetrating through the main body portion 25 and the head end portion 26. The slit 27 holds the needle member 11 assembled to the head member 12, and serves as a holding guide groove that guides the movement of the needle member 11 when the needle member 11 penetrates the head member 12 from the holding state and is stabbed into the wall. It is functioning. The slit 27 has an inner wall corresponding to the cross-sectional shape of the root portion 16 of the needle member 11 so that the needle member 11 can pass therethrough. The slit 27 has a concave groove 28 so that the wedge parts 23 and 24 pass through without resistance when the needle member 11 is passed in accordance with the positions where the wedge parts 23 and 24 are raised in the needle member 11 and the height thereof. , 28 are formed. The slit 27 and the concave grooves 28 and 28 are held with a slight interference fit so that the needle member 11 and the wedge portions 23 and 24 do not blindly move, and light resistance is felt when the needle member 11 is moved. It is preferable to have it. In this case, the needle member 11 can be distributed as a product in a set state in which the needle member 11 is incorporated in the head member 12. The needle member 11 can be moved relative to the head member 12 by driving the needle member 11 with a force exceeding a light resistance.

  Details of the cap 13 are shown in FIG. The cap 13 is made of easily deformable resin. The cap 13 includes a top plate portion 31, a peripheral body portion 32 that is integrally connected to the outer edge of the top plate portion 31, and a ring-shaped engagement portion 33 that is integrally formed inside a free end of the peripheral body portion 32. ing. The cap 13 is attached to the head member 12 by covering the head end portion 26 of the head member 12 and engaging the engaging portion 33 with the step portion between the main body portion 25 and the head end portion 26. In the illustrated example, the cap 13 has a height that covers the head end portion 26 of the head member 12, but the cap 13 covers all surfaces except for the end face on the side where the plate-like pins 14 and 15 protrude. It may be provided with a shape / structure corresponding to the total height.

  The manner in which the wall mounting tool 10 shown in FIGS. 1 to 4 is mounted on the surface WS of the wall W is shown in FIG. 5B and 5C are cross sections rotated 90 degrees from the cross section of FIG. 5A, but the position where the needle member 11 is cut through is the position of one plate pin. . As shown in FIG. 5A, the head member 12 is placed at a predetermined position on the surface WS of the wall W, and the needle member 11 is inserted into the slit 27 of the head member 12. The formed wedge parts 23 and 24 pass through the concave groove 28 formed in the slit 27. The needle member 11 is pierced into the wall W through the slit 27 of the head member 12 by hitting the root portion 16 of the needle member 11 with a tool such as a hammer. At this time, since the head member 12 guides the progress of the needle member 11 in the slit 27, even if resistance from the wall W is received, buckling, deformation, distortion, or the like does not occur.

  FIG. 5B shows a state in which the needle member 11 is guided by the slit 27 of the head member 12 and part of the needle member 11 is pierced into the wall W. The wedge portions 23 and 24 formed as cut and raised pieces on the plate-like pins 14 and 15 pass through the concave groove 28 formed in the slit 27 with almost no deformation when piercing the wall W. Further, when the wedge portions 23 and 24 pass through the wall W, depending on their hardness, the wedge portions 23 and 24 are deformed by being pressed in the down-facing direction where the inclination becomes gentle, so that the resistance to piercing is small. When the needle member 11 is driven to a predetermined depth position on the wall W, the wedge portions 23 and 24 are completely in the wall W. The needle member 11 is driven until the tool hits the head end portion 26, that is, until the root portion 16 does not jump out of the surface of the head end portion 26 and is just flush. At this time, most of the plate-like pins 14 and 15 are stuck into the wall W. Regarding the head member 12, the state in which the needle member 11 is pierced into the wall W is a state in which the needle member 11 is fixed to the wall W through the needle member 11. The article is directly attached to the head member 12 fixed to the wall W, or is engaged with an engaging tool (not shown) that is locked to the head member 12, so that the article is interposed through the engaging tool. It is indirectly attached to the wall W. Finally, the cap 13 is put on the head member 12, and the mounting of the wall mounting tool 10 on the wall W is completed as shown in FIG.

  In a state where the needle member 11 has been pierced into the wall W, the wedge portions 23 and 24 return to the raising direction due to their own restoring force from the deformation in the lying direction, and the needle member 11 receives the force in the direction of pulling out from the wall W. Sometimes, the wedge action on the wall W causes a large resistance to movement in that direction. As described above, the needle member 11 is formed on the relatively hard wall W such as concrete due to the wedge portions 23 and 24 being depressed and the guide action of the slit 27 and the concave groove 28 of the head member 12. In contrast, without changing the posture in the middle of the piercing, it is possible to pierce stably and reliably while maintaining the posture. In the stabbed state, the wall sandwiches the plate-like pins 14 and 15, and when the needle member 11 tries to move in the extraction direction, its wedge action tries to deform in the direction in which the wedge parts 23 and 24 are raised. Thus, it is possible to prevent the wall from being easily pulled out, so that the mounting property to the wall can be improved. It should be noted that the needle member 11 protrudes into the slit 27 of the head member 12 in advance and is in a set state (for example, the state indicated by the imaginary line in FIG. 11 may be driven into the wall W while the guiding action by the slit 27 is obtained by hitting the base portion 16 with a tool.

  Since the hanging force when the wall hanging article is suspended by the wall mounting tool 10 is shared and held by the two plate-like pins 14 and 15, it can be stably held. Further, if the posture of the needle member 11 when it is stabbed is not stable, the hole made in the wall swings to the left and right, and the holding strength of the stab pin decreases, but the two formed in parallel Since the plate-like pins 14 and 15 are respectively stabbed into the wall while being guided by the head member 12, the posture is stabilized and the number of holes formed in the wall can be minimized. The shapes of the leading portions 21 and 22 are examples, and are not limited thereto. The plate-like pins 14 and 15 have a uniform thickness depending on the hardness of the wall to be applied, such as a hard wall such as concrete or a wall made of a relatively soft wall material such as gypsum board. The plate thickness or the plate thickness that is gradually reduced toward the tip can be appropriately changed.

  A modification of the needle member used in the wall fitting according to the present invention is shown in FIG. FIG. 6 shows modified examples (1) to (6) of the needle member used in the wall mounting tool according to the present invention. In each modified example, (a) is a front view thereof, and (b) is a front view thereof. It is a side view. The needle member is made of a metal such as stainless steel, and includes a resin-made head member through which the needle member penetrates and a cap that covers the head member, as in the embodiment shown in FIGS. Used for wall mounting equipment. In the wall mounting tool, the wall hanging article is directly attached to the head member fixed to the wall through the needle member with the needle member being pierced into the wall (the article between the head member and the wall). Or the engagement tool engaged with the article is locked to the head member (including the case where the engagement tool is sandwiched between the head member and the wall). Mounted indirectly.

  In the modification (1), the needle member 41 used for the wall mounting tool is shown. The needle member 41 includes plate-like pins 42 and 43 having a triangular mountain-shaped head portions 21 and 22 that are thin and pointed toward the tip side, and a root portion 46 in which holes 46a and 46a are formed. These structures are the same as those of the needle member 11 shown in FIG. Wedge portions 47 and 47 are formed as cut-and-raised pieces in the central portion in the longitudinal direction in the central region in the width direction of the plate-like pins 42 and 43. The wedge parts 47, 47 are formed so as to become wider toward the rear side in the piercing direction. The other structure is the same as that of the needle member 11 shown in FIG. In the needle member 51 shown in the modified example (2), the positions where the wedge portions 57 and 57 are formed are on the tip side of the plate-like pins 42 and 43 as compared with the modified example (1). This shape is suitable when the lengths of the plate-like pins 42 and 43 are short, such as a small wall fitting. Since the other parts are the same as those in the modification (1), the same reference numerals as those used in the modification (1) are attached, and detailed description thereof is omitted.

  In the needle member 61 shown in the modified example (3), the wedge portions 67 and 67 are pointed more narrowly toward the rear side in the piercing direction than the wedge portions 47 and 47, as compared with the modified example (1). Is formed. Since the other parts are the same as those in the modification (1), the same reference numerals as those used in the modification (1) are attached, and detailed description thereof is omitted. In the needle member 71 shown in the modified example (4), the positions where the wedge portions 77 and 77 are formed are on the tip side of the plate-like pins 42 and 43 as compared with the modified example (3). About the other part, there is no place different from a modification (3).

  The needle member 81 shown in the modified example (5) is different from the wedge parts 47 and 47 in the formation position and shape of the wedge parts 87 and 87 as compared with the modified example (1). It is the area | region of the width direction side edge, Comprising: It forms in the shape of the same width along the piercing direction. Since the other parts are the same as those in the modification (1), the same reference numerals as those used in the modification (1) are attached, and detailed description thereof is omitted. In the needle member 91 shown in the modified example (6), compared with the modified example (5), the formation positions of the wedge portions are not only at the front end side but also at the two central portions in the longitudinal direction in each of the plate-like pins 42 and 43. The cutting and raising directions of the wedge part 97 and the wedge part 98 are opposite to the plate surfaces of the plate pins 42 and 43. About the other part, there is no place different from a modification (5). Since the wedge part 97 and the wedge part 98 are engaged with the wall by wedge action on both surfaces of the needle member 91, a strong holding can be obtained without paying attention to the direction of the wall at the time of piercing.

  The modification of the needle member used in the wall mounting tool according to the present invention is not limited to that shown in FIG. That is, for the wedge parts formed as cut and raised pieces, the number, formation position, shape, cut and raised direction, etc., the hardness and thickness of the stabbed wall, the type of material, etc., or the weight of the article to be locked Since various combinations are possible depending on the sheath form and the like, it is preferable to prepare various shapes in advance and select from them.

  Next, Embodiment 2 of the wall mounting tool according to the present invention will be described with reference to FIG. FIG. 7 is a diagram showing a second embodiment of the wall mounting tool according to the present invention, and shows an embodiment in which a part of the needle member is integrally formed with the head member by insert molding of the needle member. 7A is a front view seen from the end face side of the head member, FIG. 7B is a plan sectional view of FIG. 7A, and FIG. 7C is a side view of FIG.

  7 includes a metal needle member 111 and a head member 112 made of a resin material, and the head member 112 is formed by inserting the needle member 111 in advance. It is manufactured in a state of being fixed to the head member 112. The needle member 111 includes two elongated plate-like pins 114 and 115 and a root portion 116 that is a common portion for these plate-like pins 114 and 115. The holes 116a and 116a formed in the root portion 116 enhance the integrity of the resin material by flowing into the needle member 111 during the insert molding. The root portion 116 of the needle member 111 is embedded in the head member 112 and does not appear from the end surface of the head member 112. The wedge portion 123 is a cut-and-raised piece that is cut and raised with the same width at a portion closer to the root, that is, a position relatively close to the root portion 116, one on each side edge of the plate-like pins 114 and 115. . Since the wedge portion 123 is the same as that shown in the modification of the needle member 11 used in the first embodiment, detailed description thereof will not be repeated. Although there is a dimensional restriction such as a wall thickness, the wedge portion 123 can be formed at a position closer to the root portion 116 than the illustrated position.

  In the head member 112, the main body portion 125 has a cylindrical shape, but the head end portion 126 has a shape in which both end portions in the width direction of the flange member 111 are cut off, It can be used to prevent relative rotation. Protrusions 128 are formed on the piercing end surface 127 of the main body portion 125 at asymmetric positions with the flange member 111 interposed therebetween. As will be described later with reference to FIGS. 8 and 9, the protrusions 128 are used for positioning the piercing position with respect to the engaging tool.

  FIG. 8 is a view showing an example of an engagement tool used to support an article on a wall. The wall fittings 100 and 100 shown in FIG. It is attached to the wall by piercing. FIG. 8A is a front view of the engaging tool, and FIG. 8B is a side view of the engaging tool shown in FIG.

  The engaging tool 200 shown in FIG. 8 includes a main body 210 attached to a wall, and an engaging portion 220 that is formed integrally with the main body 210 and engages with an article. The main body part 210 includes extension parts 211 and 211 for stably supporting the engaging part 220. The engaging part 220 is bent between the left and right extension parts of the main body part 210 and is therefore formed integrally with the main body part 210. The engagement tool 200 is sandwiched between the wall and the wall mounting tools 100 and 100 and is fixed to the wall.

  In the main body 210, two hole groups 212 and 212 into which the two wall mounting devices 100 and 100 are respectively pierced are formed in the same manner (shape and posture) at left and right symmetrical positions. Each hole group 212 is formed in the piercing holes 213 and 213 into which the two plate-like pins 114 and 115 of the needle member 111 of the wall mounting tool 100 are inserted, and the main body portion 125 of the head portion 212 of the wall mounting tool 100. Two insertion holes 214 and 214 into which the two protrusions 128 and 128 are fitted are formed. Each piercing hole 213 is devised in the shape of the hole so that the wedge portion 123 which is a cut and raised piece can easily pass therethrough. In other words, each piercing hole 213 is formed with an enlarged portion 213a continuously in an L shape so that the wedge portion 123 can easily pass through. By considering the shape of the piercing hole 213, the two protrusions 128, 128 formed on the main body portion 125 of the head member 112 fit into the insertion holes 214, 214 formed on the main body portion 210 of the engaging tool 200. This is because the wall mounting tool 100 can only be fitted in one position at one position, so that positioning is accurately performed when the piercing is completed and the projection 128 is fitted in the insertion hole 214. In the example of the illustrated engaging tool, the two piercing holes 213 are arranged side by side, but may be an engaging tool arranged vertically if necessary.

  The engaging tool 230 shown in FIG. 9 is different from the engaging tool 200 shown in FIG. 8 in that a main body part 210 attached to a wall and an engaging part 220 formed integrally with the main body part 210 and engaged with an article. And the main body part 210 is common in that the extension parts 211 and 211 are provided. The engaging tool 230 shown in FIG. 9 is a metal fitting used for a concrete piercing pin, and is sandwiched between a wall and the wall mounting tool 100 using a single wall mounting tool 100 as shown in FIG. It is fixed to the wall. Therefore, one hole group 232 is formed in the central portion of the main body 210. The hole group 232 extends in the vertical direction, a piercing hole 233 into which the plate-like pins 114 and 115 (one pin may be substituted for two pins), and the main body of the head portion 212 of the wall fitting 100. It consists of insertion holes 234 and 234 into which two projections 128 and 128 formed in the portion 125 are fitted. The engaging tool 230 is the same as the example shown in FIG. 8 except that one wall mounting tool 100 is used. However, since the needle member 111 is in the same state even if it is rotated 180 degrees, this point cannot be distinguished.

  In the case of the embodiment shown in FIG. 1 to FIG. 5, that is, in the case of the wall mounting tool 10 of the type used by piercing the needle member 11 into the head member 12, a stopper for limiting the piercing of the needle member 11 12 may be provided. For example, in the case where the plate-like pins provided on the needle member 11 are two plate-like pins 14 and 15, the root portion 16 between the plate-like pins 14 and 15 abuts on the head member 12, or In the case of a book-like pin, it is possible to provide a stopper against which shoulder portions provided on both sides of the pin abut. About processing of needle member 11, after processing with a press, hardening processing is performed (the hardness obtained by quenching temperature changes). As the material of the needle member 11, for example, carbon tool steel (SK material) and spring steel 65Mn are used, and a stainless material (SUS301) or the like can be used for a relatively soft concrete wall.

  In the wall mounting tool according to the present invention, it is used for attaching an article to a wall body. However, the wall body is a general household mortar wall, a plaster board (a soft material containing a lot of moisture or a material having hardness). Or a wall material made of wood or plywood, or a concrete wall. As a wall material composed of wood or veneer board, in addition to solid wood, natural wood decorative plywood in which a thin board of wood is pasted on a base material such as plywood or MDF (medium fiber board), It is obvious that it may be a synthetic resin plywood in which resin-processed paper or vinyl is attached to the surface of the plywood, or a printed plywood in which wood is directly printed on the plywood. Moreover, as a coating wall, the mortar which made the raw material the diatomaceous earth and slaked lime with a high odor function may be sufficient, for example. It may be plaster plaster or dolomite plaster.

As for the shape of the plate-like pin, the piercing pin provided with the plate-like pin whose thickness is gradually reduced toward the tip side is suitable for use as a gypsum board or mortar. The tip of the plate-like pin can be sharpened and the thickness of the tip can be reduced. The soft wall can be pierced (dried) without being damaged even if the thickness of the tip is reduced.
On the other hand, for hard walls such as concrete, plate-like pins depend on the material and processing method, but if they do not cause damage such as breakage or bending, the length from the root to the tip About a width dimension or plate | board thickness, a suitable change is possible according to a use aspect. In addition to ensuring the thickness so that the pin is stable and not damaged, the thickness of the tip may be reduced.
The size of the needle member should be selected in consideration of the weight of the article to be attached, the nature of the wall material (hardness, etc.), the number of piercing pins used, the load conditions applied to the individual piercing pins, etc. Is preferred. For example, the plate thickness of the plate-like pin can be increased as the hardness of the wall is higher. Therefore, it is preferable to prepare a number of piercing pins having specifications and select a safe specification from among them according to the use situation.
