Description

  The present invention relates to a gardening clip for fixing a flexible sheet-like member to a rod-like member.

  For example, a structural material such as a column or a horizontal rail is arranged around an orchard or a greenhouse, and the structural material may be covered with a flexible sheet-like member such as a sheet or a net. The flexible sheet-like member needs to be fixed to the structural material. For the fixing, for example, a clip as shown in Patent Document 1 is used.

  The clip of Patent Document 1 has a configuration in which a pair of knobs are provided in a substantially C-shaped cylindrical holding part and a lock piece is connected to the inner surface of one of the pair of knobs via a thin part. The pair of knobs are pushed into the V-shaped facing space of the pair of knobs so that the pair of knobs are separated to elastically increase the holding width of the cylindrical holding part. It is designed to be narrowed (locked).

Japanese Patent No. 4002922

  In the clip of Patent Document 1, the thin-walled portion is bent when the lock-locked state is brought into the locked state because the tension lock piece is connected to the inner surface of one of the pair of knobs via the thin-walled portion. There is a risk. When such bending occurs, the tension force by the tension lock piece is weakened, so that the fixing strength of the flexible sheet-like member with respect to the column may be insufficient.

  Further, in the case of the clip of Patent Document 1, the tension lock piece is hidden in the V-shaped facing space even when the tension locking piece is not pushed into the V-shaped facing space (unlocked state). There is also a concern that it is difficult to visually confirm this from the outside when in the locked state, because of the relationship placed in a closed state.

  In view of such circumstances, the present invention increases at least the fixing strength of the flexible sheet-like member with respect to the rod-like member in the gardening clip for fixing the flexible sheet-like member to the rod-like member such as the support column. It is an object.

  The present invention is a horticultural clip for fixing a flexible sheet-like member to a rod-like member, and a sandwiching portion that is sandwiched between the rod-like member and configured so that a sandwiching width can be elastically expanded or reduced, A pair of knobs formed integrally with the clamping part and operated to elastically expand the clamping width of the clamping part; and formed integrally with the clamping part and bent from an upright position to a tilted position A locking piece for elastically reducing the clamping width of the clamping part by stretching the pair of knobs when they are pushed in a wedge shape between the pair of knobs, The lock piece is arranged in a direction orthogonal to the facing direction of the pair of knob pieces.

  In this configuration, the lock piece is provided at a position distant from the pair of knob pieces, and the lock piece is connected to the pair of knob pieces via the thin portion as in Patent Document 1 described above. is not.

  Therefore, in the above configuration, when the lock piece is bent in a tilted posture and pushed between the pair of knob pieces, the lock piece bends between the pair of knob pieces unlike the above-mentioned Patent Document 1. Since it is in a state of stretching without any loss, the stretching force is not weakened but rather becomes as strong as possible.

  As a result, when the flexible sheet-like member is fixed to the rod-like member using the horticultural clip according to the present invention, the fixing strength does not become insufficient, but rather is increased as much as possible.

  By the way, the said clamping part is made into the cylindrical member from which the one place of the circumferential direction was isolate | separated, and a pair of said tab is made into a plate-shaped member, and it extends to the said clamping part to radial direction outward. By connecting them, a V-shaped space is created between the opposing sides, and the lock piece is located on one side of the pair of knobs in the direction of the central axis of the sandwiching portion made of the cylindrical member. It is preferable that the sandwiching portions are connected in a standing posture so as to extend outward in the radial direction.

  In this structure, the shape of the said clamping part, the said pair of knob piece, and a lock piece is specified. According to this specification, it becomes possible to change the pressing depth of the lock piece, and it becomes possible to appropriately expand or reduce the clamping width of the clamping part by changing the pushing depth, etc. It becomes possible to arbitrarily adjust the fixing strength of the flexible sheet-like member with respect to the rod-like member.

  Moreover, it is preferable that the said lock piece is arrange | positioned so that it may adjoin the said pair of knob piece in the direction orthogonal to the opposing direction of the said pair of knob piece.

  In this configuration, when the lock piece is pushed between the pair of knob pieces, the wide rectangular portion of the lock piece advantageously increases the degree of separation of the pair of knob pieces as much as possible. Become.

  Also, a plurality of groove-shaped portions are provided side by side from the base side to the tip side on the inner surfaces of the pair of knob pieces, and the lock piece is formed in a plate shape and bent in a tilted posture. It is preferable that both sides along the extending direction of the lock piece are fitted into any of the plurality of groove-shaped portions when the lock piece is pressed.

  In this configuration, when the lock piece is bent in a tilted posture and pushed between the pair of knob pieces, the state is held relatively firmly.

  The horticultural clip according to the present invention can at least increase the fixing strength of the flexible sheet-like member with respect to the rod-like member.

  BEST MODE FOR CARRYING OUT THE INVENTION Best modes for carrying out the present invention will be described in detail below with reference to the accompanying drawings.

  1 to 9 show an embodiment of the present invention. In the figure, 5 indicates the entire gardening clip.

  Prior to detailed description of the horticultural clip 5, its use target will be described. Although not shown, for example, around the orchard or the greenhouse, a structure in which a rod-like member 1 such as a column or a crosspiece is combined is arranged, and in the structure, a flexible sheet-like member 2 such as a sheet or a net is arranged. May be attached to cover. When the flexible sheet-like member 2 is fixed to the rod-like member 1, the gardening clip 5 according to the present invention is used.

  The rod-shaped member 1 is, for example, a cylindrical steel pipe, a stainless steel pipe, an aluminum pipe, or the like. The steel pipe may be subjected to a rust prevention treatment such as galvanization. Further, the outer shape of the rod-shaped member 1 may be an ellipse or a square (for example, a triangle, a quadrangle, a pentagon, etc.), and may be solid instead of a hollow cylinder.

  As the flexible sheet-like member 2, a sheet that is transparent or translucent and mainly intended to keep warm and prevent rain, and a net for mainly preventing the entry of pests and birds and beasts are used.

  The sheet, which is one of the flexible sheet-like members 2, is made of a sheet of synthetic resin having transparency or translucency such as polyolefin such as polyethylene or polypropylene, polyester resin such as polyethylene terephthalate or polylactic acid, or polyvinyl chloride. The size and thickness are appropriately set.

  Moreover, the said net | network which is one of the flexible sheet-like members 2 makes the linear body and band which consist of synthetic resins, such as polyethylene, polypropylene, polyester, nylon resin, polyester, natural resins, such as hemp, cotton, etc. mesh shape. The strength and the mesh size are appropriately set in consideration of the size of pests and birds and beasts that should be prevented from entering.

  The horticultural clip 5 shown in this embodiment includes a clamping part 6, a pair of knob pieces 7, 8, and a lock piece 9.

  The clamping portion 6 is a cylindrical member separated at one circumferential position so as to be clamped by the rod-shaped member 1, and the distal end side opening width W1 and the clamping width W2 with respect to the rod-shaped member 1 are elastically expanded or reduced. It is configured to be possible. As shown in FIG. 3, the clamping width W2 is the maximum spacing between the spacings of the pair of clamping pieces 6a and 6b.

  This clamping part 6 is formed in a substantially C shape in a side view, and has a pair of clamping pieces 6a and 6b and a connecting part 6c that couples the pair of clamping pieces 6a and 6b.

  The inner wall surface of the sandwiching portion 6 is configured such that the entire inner surface, that is, the entire inner wall surface of the pair of sandwiching pieces 6 a and 6 b and the entire inner wall surface of the connecting portion 6 c are in close contact with the outer peripheral surface of the rod-shaped member 1. Thereby, the flexible sheet-like member 2 comes to be sandwiched between the outer peripheral surface of the rod-like member 1 and the inner wall surface of the clamping portion 6.

  Protruding pieces 6d and 6e projecting radially outward are provided on the respective distal end sides of the pair of sandwiching pieces 6a and 6b, and the inner surfaces of the projecting pieces 6d and 6e are tapered. Thereby, the opposing space | interval of each protrusion piece 6d and 6e is gradually widened toward the front end side.

  The pair of knobs 7 and 8 are formed integrally with the sandwiching portion 6 and are provided for operating the tip-side opening width W1 and the sandwiching width W2 of the sandwiching portion 6 to be elastically enlarged. ing.

  The pair of knobs 7 and 8 is a plate-like member whose outer shape is formed in an inverted trapezoidal shape, and when the sandwiching portion 6 is divided into three equal regions in the circumferential direction, one side region and the other side By connecting each boundary portion between the region and the intermediate region so as to extend outward in the radial direction of the sandwiching portion 6, a V-shaped space is created between the opposing portions in a side view.

  Further, on the inner surfaces of the pair of knobs 7 and 8, protrusions 7 a and 8 a are provided in the middle of the width direction (the direction along the central axis direction of the sandwiching portion 6). The protrusions 7a and 8a are provided in a substantially full length range from the base side to the tip side of the pair of knobs 7 and 8.

  A plurality of (for example, three) groove-like portions (hereinafter referred to as inner groove-like portions) 7b and 8b are provided on the protruding portions 7a and 8a. The inner groove portions 7b and 8b are formed in a direction orthogonal to the longitudinal direction of the ridges 7a and 8a, and are waved by being arranged in parallel in the longitudinal direction of the ridges 7a and 8a at equal intervals. ing.

  The inner groove portions 7b and 8b are formed in the tilted position by engaging both sides of the lock piece 9 when the lock piece 9 is pushed into the opposed position of the pair of knob pieces 7 and 8 with the lock piece 9 tilted. Is provided to hold

  The inner groove portions 7b and 8b are formed in a curved surface shape such as a U shape in cross section. As a result, when the lock piece 9 is tilted, it is easy to fit into the inner groove portions 7b, 8b, and when the lock piece 9 is raised, it is easy to pull out from the inner groove portions 7b, 8b. .

  A plurality of groove-like portions (hereinafter referred to as outer groove-like portions) 7c and 8c for preventing slipping are provided on the outer surfaces of the pair of knobs 7 and 8, respectively. The outer groove portions 7c, 8c are formed in the width direction (the direction along the central axis direction of the sandwiching portion 6) on the inner surfaces of the pair of knob pieces 7, 8, and the extending direction of the pair of knob pieces 7, 8 Are arranged in parallel at equal intervals to form a wave shape. The outer groove portions 7c and 8c are formed in a rectangular shape in cross section.

  The lock piece 9 is formed integrally with the sandwiching portion 6 to elastically reduce the opening width W1 and the sandwiching width W2 of the sandwiching portion 6 and to maintain the reduced state. Is provided.

  The lock piece 9 is connected to a position adjacent to one side of the pair of knob pieces 7 and 8 in the connecting part 6c of the holding part 6 in an upright posture so as to extend outward in the radial direction of the holding part 6. ing. The position adjacent to one side of the pair of knobs 7 and 8 is the position of the pair of knobs 7 and 8 in the central axis direction of the sandwiching portion 6 (direction perpendicular to the opposing direction of the pair of knobs 7 and 8). One side.

  As shown in FIGS. 1 to 3, the full length dimension of the lock piece 9 in the standing posture is set such that its tip side protrudes radially outward from the tips of the pair of knob pieces 7 and 8.

  A distal end side region 9a from approximately the center to the distal end in the protruding direction of the lock piece 9 is formed in a rectangular shape that is wider than the proximal side region 9b from approximately the center to the root in the protruding direction. For this reason, the front end side region 9a can also be referred to as a “wide rectangular portion”.

  As shown in FIG. 4, the distal end side region 9a is slightly warped in the width direction, in other words, the intermediate portion in the width direction of the distal end side region 9a is directed toward the pair of knobs 7 and 8. It is formed in a curved shape so as to protrude.

  On the other hand, the base side region 9b is narrower than the tip side region 9a and is formed in a band shape. For this reason, the root side region 9b can be rephrased as a narrow strip portion. A thin portion 9c is provided in the middle of the base side region 9b in the longitudinal direction. The thin-walled portion 9c becomes a starting point of bending when the lock piece 9 is bent from the standing posture to the tilting posture.

  Then, the lock piece 9 is bent about 90 degrees from the standing posture to the tilting posture and is pushed in a wedge shape between the pair of knobs 7 and 8 so as to separate the pair of knobs 7 and 8 from each other. The front end side opening width W1 and the sandwiching width W2 of the sandwiching portion 6 are stretched to function elastically.

  Thus, when the lock piece 9 is tilted, both sides (end portions along the protruding direction) of the lock piece 9 are fitted into the inner groove portions 7b and 8b of the pair of knob pieces 7 and 8, respectively. Accordingly, the tilting posture of the lock piece 9 and the reduced state of the distal end side opening width W1 and the clamping width W2 are maintained.

  Such a horticultural clip 5 is made of, for example, polyethylene, ABS resin, AAS resin, ASA resin, polyacetal resin, polyester resin, elastomer, rubber, and the like, and is manufactured by molding.

  The pair of sandwiching pieces 6a and 6b are formed to be thicker than the connecting portion 6c. Thus, when the pair of gripping pieces 7 and 8 are brought close to each other, the pair of sandwiching pieces 6a and 6b The connecting portion 6c is elastically deformed without deformation of the b 6b, so that the distal end side opening width W1 and the holding width W2 of the pair of holding pieces 6a and 6b are enlarged or reduced.

  Next, the usage method of the gardening clip 5 will be described.

  First, the flexible sheet-like member 2 is placed on the surface of the rod-like member 1. On the other hand, as shown in FIG. 6, the pair of knobs 7, 8 of the gardening clip 5 are picked with human fingers so as to be close to each other, whereby the opening width W <b> 1 at the front end side of the holding part 6 shown in FIG. After extending the width W2 to be larger than the outer diameter of the rod-shaped member 1 as indicated by W1 ′ and W2 ′ in FIG. 6, the inner wall surface of the sandwiching portion 6 of the gardening clip 5 is covered with the outer circumferential surface of the rod-shaped member 1. Cover. Thereafter, when the fingers are separated from the pair of knobs 7 and 8 to reduce the opening width W1 and the clamping width W2 of the clamping part 6 as shown in FIG. 3, the inner wall surface of the clamping part 6 becomes a flexible sheet shape. It is pressed against the outer peripheral surface of the rod-shaped member 1 from above the member 2.

  As a result, as shown in FIG. 9, the flexible sheet-like member 2 is wound around the outer peripheral surface of the rod-like member 1 and is fitted so that the entire inner wall surface of the clamping portion 6 matches the outer peripheral surface of the rod-like member 1. Accordingly, the flexible sheet-like member 2 is sandwiched between the inner wall surface of the sandwiching portion 6 and the outer peripheral surface of the rod-like member 1.

  Thereafter, as shown in FIG. 7, the tip side region 9 a is wedge-shaped between the pair of knobs 7 and 8 by pressing and tilting the finger against the tip side region 9 a of the lock piece 9 in the standing posture. The inner side of the distal end side region 9a and the appropriate inner groove-like portion of the plurality of inner groove-like portions 7b, 8b provided on the protrusions 7a, 8a of the pair of knobs 7, 8. Engage with 7b and 8b.

  As a result, the lock piece 9 is stretched between the pair of knobs 7 and 8 and the pair of knobs 7 and 8 are separated from each other, so that the distal end side opening width W1 and the clamping width of the clamping part 6 are separated. W2 is elastically reduced, and the inner wall surfaces of the pair of sandwiching pieces 6a and 6b are strongly pressed against the outer peripheral surface of the rod-shaped member 1 through the flexible sheet-like member 2. Thereby, the flexible sheet-like member 2 can be firmly fixed to the rod-like member 1.

  When removing the horticultural clip 5 attached in this manner, first, the lock piece 9 is lifted up so that it is pulled out from between the pair of knob pieces 7, 8, and then the pair of knob pieces 7, By pinching 8, the distal end side opening width W <b> 1 and the clamping width W <b> 2 of the clamping unit 6 are elastically expanded. In this state, the gardening clip 5 may be pulled outward in the radial direction so as to be separated from the rod-shaped member 1.

  Since the outer groove portions 7c and 8c are provided on the outer surfaces of the pair of knobs 7 and 8 as described above, the fingers are less likely to slip when the pair of knobs 7 and 8 are picked. Thereby, it becomes easy to maintain the state picked with the finger.

  In addition, since the inner surfaces of the projecting pieces 6d and 6e of the pair of sandwiching pieces 6a and 6b are formed in a tapered shape, when the tapered inner surface is pressed onto the outer peripheral surface of the rod-shaped member 1 from above the flexible sheet-like member 2 It becomes easy to fit the sandwiching part 6 so as to sandwich the rod-like member 1.

  Further, as shown in FIG. 4, the shape of the lock piece 9 in which the tip end region 9 a is slightly bent in the width direction, in other words, the intermediate portion in the width direction is protruded toward the pair of knobs 7 and 8. Since the curved shape is adopted, when the lock piece 9 is tilted, it is easy to press a finger against the distal end side region 9 a and a force to tilt the lock piece 9 is easily applied.

  In addition, since the plurality of inner groove-like portions 7b and 8b are provided on the protrusions 7a and 8a on the inner surfaces of the pair of knob pieces 7 and 8, the push-in depth of the lock piece 9 can be changed stepwise. In addition, the flexible sheet-like member for the rod-like member 1 can be obtained by changing the push-in depth stepwise so that the distal end side opening width W1 and the sandwiching width W2 of the holding portion 6 can be enlarged or reduced stepwise. The fixing strength of 2 can be arbitrarily adjusted.

  Further, as shown in FIG. 4, both sides of the distal end side region 9 a of the lock piece 9 are formed in a rounded shape, and as shown in FIG. 3, the inner groove portions 7 b and 8 b have a cross-section U Since it is formed in a letter shape, when the lock piece 9 is caused, only the force for causing it is applied to the lock piece 9, and both sides of the distal end side region 9a of the lock piece 9 become the inner groove portions 7b, 8b. Therefore, the lock piece 9 can be returned to the standing posture relatively easily.

  Moreover, as shown in FIGS. 1 to 3, since the overall length of the lock piece 9 in the standing posture is longer than that of the pair of knobs 7 and 8, the lock piece 9 is in the standing posture. Even if the holding portion 6 is sandwiched between the rod-like members 1 in the state, that is, in the unlocked state, this can be recognized at a glance. That is, it is convenient, for example, that it is possible to easily visually check whether or not the holding portion 6 held between the rod-like members 1 is in a locked state.

  As described above, in the horticultural clip 5 according to the embodiment to which the present invention is applied, the lock piece 9 is provided at a position separated from the pair of knob pieces 7, 8. It is not in the form of “locking the lock piece to the knob piece via the thin wall portion”.

  Therefore, according to the horticultural clip 5 of this embodiment, when the plate-like lock piece 9 is bent in a tilted posture and pushed between the pair of knobs 7 and 8, unlike the above-mentioned Patent Document 1, the plate-like lock piece 9 has a plate-like shape. Since the lock piece 9 is in a state of being stretched without being bent between the pair of knobs 7 and 8, the tension force does not become weak but rather becomes as strong as possible.

  Thereby, when fixing the flexible sheet-like member 2 to the rod-like member 1 using the horticultural clip 5 according to the present invention, unlike the Patent Document 1, the fixing strength is not insufficient, but rather as much as possible. Will be enhanced.

  In addition, this invention is not limited only to the said embodiment, It can change suitably in the range equivalent to the claim and the said range.

  (1) In the said embodiment, although the case where the shape of the inner wall surface of the clamping part 6 was made circular was mentioned as an example, this invention is not limited only to this.

  For example, the shape of the inner wall surface of the sandwiching portion 6 can be a shape that follows the shape of the outer peripheral surface of the rod-shaped member 1 that is the object of use of the gardening clip 5.

  (2) In the said embodiment, the whole inner wall surface of the clamping part 6, ie, the form which sticks the inner wall surface of a pair of clamping piece 6a, 6b, and the inner wall surface of the connection part 6c to the outer peripheral surface of the rod-shaped member 1 is mentioned as an example. However, the present invention is not limited to this.

  For example, only the inner wall surfaces of the pair of sandwiching pieces 6 a and 6 b can be brought into close contact with the outer peripheral surface of the rod-shaped member 1. In that case, the whole inner wall surface of the pair of sandwiching pieces 6a, 6b may be in close contact with the outer peripheral surface of the rod-shaped member 1, or a part of the inner wall surface of the pair of sandwiching pieces 6a, 6b may be formed on the rod-shaped member 1. You may make it the form closely_contact | adhered to an outer peripheral surface.

  (3) In the above embodiment, the shape of the pair of knobs 7 and 8 is not particularly limited as long as they can be picked by a finger, and the lock piece 9 is of a size that can be pushed by a finger. The shape is not particularly limited. Furthermore, it is possible to provide a plurality of protrusions 7 a, 8 a in the longitudinal direction of the clamping part 6.

  (4) In the above embodiment, the lock piece 9 is arranged so as to be adjacent to the pair of knobs 7 and 8 along the central axis of the sandwiching portion 6, but the present invention is limited to this. is not.

  For example, the lock piece 9 is not shown, but can be disposed between the pair of knob pieces 7 and 8.
