PROBLEM TO BE SOLVED: To provide an assembled stage and jack mechanism which can be easily assembled.SOLUTION: The assembled stage comprises a base composed of a plurality of supporting members, and a plurality of floor members installed on the base. The floor member is fixed by engagement with the support member. Since the assembled stage does not use bolts, screws, etc., it is easy to assemble and easy to remove. Since the assembled stage is composed of a plurality of members, it is easy to carry the members and the storage space when unnecessary is small. Because the stage includes a base, moisture and the like can be avoided even if installed on the ground. By adjusting the shape of the floor member, the stage can be assembled into other shapes, such as a circle, in addition to a square shape. If an artificial turf layer is laminated on the floor member, the stage can be used as a green for practicing golf.SELECTED DRAWING: Figure 13

Description

  The present invention relates to an assembling stage that includes a pedestal and a floor member and can be easily assembled by engaging a plurality of floor members with the pedestal, and a jack mechanism that can adjust the height of the stage.

  Temporary stages may be used in lecture halls and hotel dinner shows. In addition, when a tent or other simple facility is used for evacuation in the event of a disaster such as an earthquake or heavy rain, it is possible to avoid a decrease in humidity and body temperature due to rainwater by providing a stage such as a floorboard between the simple facility and the ground.

  As such a stage, there is a configuration in which a plurality of rectangular box-like objects are connected in series, which are used in banquet facilities. However, since a large number of box-like objects are required to create a wide stage, it is not easy to store when not needed. As a stage that can be stored in a space-saving manner, there is a foldable stage composed of a top plate and folded legs (Patent Document 1). Although the folding stage has an advantage that it can be easily set, it is difficult to install a stage having a large area in a folding manner.

  On the other hand, there is an assembly-type floor material as a member that can set up a floor plate freely (Patent Document 2). The floor material described in Patent Document 2 is characterized in that two adjacent floor materials are fixed by a base member. By using the base member, even if the floor material shrinks due to temperature changes, no gaps or steps are generated between the floor materials, and damage such as cracks does not occur at the fastening part during assembly.

  In addition, there is also a prefabricated floor material that is engaged with each other to form a joint-like portion and can stably maintain the binding force (Patent Document 3). A concave portion and a convex portion that can be fitted to the adjacent floor material are formed on both side surfaces and front and rear surfaces of the floor material. Construction and maintenance can also be done easily.

  In the event of disasters such as earthquakes and tsunamis that frequently occur in recent years, victims who are unsuitable for group life may wake up in tents. If there is a stage between the ground and the tent, the living environment is improved, but it is important that it can be easily set up in an emergency. However, the flooring materials described in Patent Document 2 and Patent Document 3 are intended to be used permanently and have a structure that does not leave, so it takes time to set up and is not easy to remove. It is also convenient if the stage shape can be adjusted arbitrarily. Therefore, it is desired to develop an assembly stage that can be easily set up and removed, an increase / decrease in the assembly area, and the shape of the installation area can be arbitrarily selected, and an assembly stage that can cope with the unevenness of the installation surface.

  From the viewpoint of effective use of land, it is convenient if the baseball ground can be diverted to a golf practice field during the baseball off-season. If artificial turf is laminated on the upper part of a substantially circular stage, it can be used as a golf practice green imitating a golf course. At that time, golf can be practiced without damaging the ground by providing a hole for the ball to enter on the stage and providing a pole for indicating the position of the hole. In addition, since it is used during off-season, it is desirable that it can be easily disassembled so that it can be easily set up and reused. Therefore, it is desired to develop an assembly stage that can be set in any shape such as a circle or a rectangle, can be reused, and can be used as a golf practice green.

  Furthermore, there is a case where it is desired to adjust the height of the depressed portion, for example, when a part of the ground is depressed due to use after assembly of the stage. It would be convenient if the height could be adjusted without disassembling the stage after assembly. Therefore, it is desired to develop an assembling stage that can easily cope with unevenness generated after assembling and a jack mechanism capable of such adjustment.

  In view of the above-described present situation, an object of the present invention is to provide a reusable assembly stage that can be set up and removed in a short time.

  Moreover, it aims at providing the jack mechanism which can adjust the height of an assembly-type stage simply.

  Hereinafter, the present invention will be described in detail with reference to the drawings.

(1) Assembly-type stage FIG. 1 shows one embodiment of the assembly-type stage 100 of the present invention. A floor member 40 indicated by reference numerals 40 (a), 40 (b), and 40 (c) is laid over the support member 20 constituting the base 10 without any gaps, forming a substantially rectangular stage. As shown in FIG. 2, the pedestal 10 includes a plurality of rod-shaped support members 20 indicated by reference numerals 20 (a) and 20 (b) arranged in a plane. FIG. 2 shows a mode in which the jack mechanism 27 is disposed below the support member 20. However, when the assembly type stage 100 is not inclined or installed on a flat ground such as a ground or a baseball field. The jack mechanism 27 may be omitted. FIG. 2 shows a mode in which the support member 20 and the jack mechanism 27 below the support member 20 are connected via the connection member 30. The support member 20 has a first locking portion 23 or a second locking portion 25 for locking the floor member 40 installed on the upper portion of the base 10. A member having the first locking portion 23 is referred to as a support member (a) 20 (a), and a member having the second locking portion 25 is referred to as a support member (b) 20 (b). The pedestal 10 has a row of support members (a) 20 (a) and a row of support members (b) 20 (b) arranged in parallel. Each floor member 40 is installed on two support members 20, and is engaged with the first locking portion 23 or the second locking portion 25 of the support member 20 at the trunk portion or the end portion of the floor member 40.

  Since the assembly-type stage 100 includes the plurality of support members 20 and the floor member 40, the assembly-type stage 100 can be easily assembled and removed. Further, by using a plurality of members, the stage can be assembled to an arbitrary size, and can be easily increased in size simply by increasing the number of members. In the case of the assembly type stage 100 assembled in a square shape, it is possible to easily assemble L-type, H-type, E-type, etc. by simply changing the arrangement. For a circular shape, an oval shape including an egg shape, a triangular shape, and other indefinite shapes, the planar shape of the floor member 40 located around the assembling stage 100 and the shape of the floor member 40 related thereto may be appropriately adjusted. Regardless of the shape, since the pedestal 10 is located below the floor member 40, moisture does not directly propagate to the floor member 40 even when the installation surface has humidity such as the ground. If you set up a stage with artificial grass on top of the ground, such as a baseball field or a riverbed, you can make it a simple green for golf practice in a natural environment. Furthermore, it can be used as a stage, a podium, a temporary shelter, or an outdoor floor during a disaster. Since the assembly stage 100 does not use bolts, screws, nuts, etc. during assembly, it can be easily assembled, disassembled and reused, and the time required for these can be greatly reduced compared to conventional methods. it can.

Each floor member 40 is constructed by two support members 20, and two ends of two floor members 40 adjacent in the longitudinal direction are engaged with the common support member 20. Therefore, the pedestal 10 can be configured with a smaller number of support members 20 than the floor member 40. The number and shape of the supporting member 20 and the floor member 40 to be used can be appropriately set according to the size and shape of the assembly-type stage 100, the ease of carrying each member, and the like. Note that the pedestal 10 is not limited to horizontal as long as it is substantially planar, and may be inclined.

(3) Consecutive Member A plurality of support members 20 constituting the base 10 can be continuously provided by the continuous member 30. The continuous member 30 is formed of a long member and can be easily attached to and detached from the support member 20. By interposing the connecting member 30 when the base 10 is assembled, the support member 20 can be easily positioned. Further, when the jack mechanism 27 is provided, the jack mechanism 27 can be maintained upright. As such a continuous member 30, there is a stripe or the like having a spherical or bowl-shaped fastening part 31 at the end shown in FIG. If the stripe fixing portion 21 is formed on the support member 20 side, a plurality of support members 20 can be connected by the fastening portion 31 and the stripe fixing portion 21 of the support member 20. As shown in FIG. 3A, when the jacking mechanism 27 is mounted with the connecting fixing member 28 shown in FIG. A through hole oh may be formed in the blade 28 "formed on the outer periphery of the blade and used as the stripe fixing portion 21, and the support members 20 may be connected to each other. The connection fixing member 28 will be described later. When the formed through-hole oh is used as the stripe fixing portion 21, not only the connection between the support members 20 but also the vertical inversion of the support member 20 can be stabilized. Although not shown, a through hole oh may be formed in the support member 20 and used as the stripe fixing portion 21. As shown in FIG. 11, the stripe fixing portion 21 may be formed on the jack base of the jack mechanism 27 or the like. Two or more connecting members 30 may be connected to one stripe fixing portion 21 to connect the support members 20 to each other. The continuous member 30 may be made of metal such as aluminum, iron, or alloy, or may be made of synthetic resin such as polyethylene or polypropylene, or fiber reinforced plastic such as FRP.

As the support member 20, a lattice structure is formed at the lower part of a long plate-like object having the second locking portion 25. The truss structure may be a Warren truss, a platform truss, a howtruss, or the like. In addition, a leg portion having a T-shape in a cross-sectional view may be formed in the lower part of the long plate-like object to ensure strength.

  The support member 20 may include a first locking portion 23 and / or a second locking portion 25 on the top surface, and may include a connection fixing mechanism for connecting and fixing the support member 20 in the longitudinal direction. For example, as shown in FIG. 4 (B), the connecting projections 29 that hang down may be integrally formed at both ends of the long plate-shaped object that constitutes the support member 20. Thus, the connection fixing member 28 may be integrally formed. Further, the connecting convex portion 29 may be integrally formed at one end, and the connecting fixing member 28 may be integrally formed at the other end. When the jack mechanism 27 for height adjustment is disposed below the support member 20, the connection fixing member 28 may have a jack mechanism mounting portion.

  The material of the support member 20 may be made of metal such as aluminum, iron, or alloy, may be made of synthetic resin such as polyethylene or polypropylene, fiber reinforced plastic such as FRP, or a composite thereof. The lengths of the protrusions of the first locking portion 23 and the second locking portion 25 formed on the support member 20 can be selected as appropriate as long as the floor member 40 can be fixed by engagement. Further, the height of the support member 20 from the installation surface is arbitrary, and the height of each row of the support members 20 used for the base 10 may be the same or different. For example, when the pedestal 10 is assembled by adjusting the height of the support members 20 so that each row of the support members 20 increases in a certain direction, the assembled assembly stage 100 can be inclined.

  FIG. 6A shows a lattice-like object 47 constituting a floor member (b) 40 (b) having a second convex portion (a) 45 (a) and a second convex portion (b) 45 (b). It is a top view. As shown in the side view of FIG. 6B, the second protrusion (a) 45 (a) and the second protrusion (b) 45 (b) are in the same direction with respect to the longitudinal direction of the lattice-like object 47. The second protrusion (b) 45 (b) protrudes outward from the end of the lattice-like object 47 and is fixed. These convex portions are members having a second convex portion (a) 45 (a) or a second convex portion (b) 45 (b) made of wood, synthetic resin, metal, or a composite thereof. It is attached between the two flat bars 41 in the center of the lattice-like object 47 by bolts, screws, or other fixing members. The same applies to the first convex portion 43. The second convex portion (a) 45 (a) and the second convex portion (b) 45 (b) have different depths from the top surface of the lattice 47 as shown in FIG. Between the two convex portions (a) 45 (a) and the bottom of the lattice-like object 47, there is a gap into which the second convex portions (b) 45 (b) can be inserted. In FIG. 6A, a pair of second convex portions (a) 45 (a) and second convex portions (b) 45 (b) are provided between the central flat bars 41 constituting the floor member 40. Although the aspect provided is shown, it is not limited to the center. For example, one set may be provided at both ends in the width direction. The same applies to the first convex portion 43.

  An example of a member for forming the first convex portion 43, the second convex portion (a) 45 (a), and the second convex portion (b) 45 (b) between the two flat bars 41 is shown in FIG. Shown in A). In any case, a convex portion (first convex portion 43, second convex portion (a) 45 (a), second convex portion (b) 45 (b)) and a fixing portion (43 that is integrally connected to the convex portion) ', 45 (a)', 45 (b) '). These fixing parts are formed with through holes (oh) for fastening with screws or bolts, and if fixed with bolts, nuts or other fixing tools between the two flat bars 41 via the through holes (oh), The first convex portion 43, the second convex portion (a) 45 (a), or the second convex portion (b) 45 (b) can be formed at an arbitrary position of the flat bar 41. FIG. 7B shows a perspective view when a member having the second convex portion (a) 45 (a) and a member having the second convex portion (b) 45 (b) are adjacent to each other. It turns out that the 2nd convex part (a) 45 (a) and the 2nd convex part (b) 45 (b) overlap.

  FIG. 8 shows a partial perspective view of two flat bars 41 to which the first convex portion 43 and the second convex portion (b) 45 (b) are fixed, and a partial perspective view of the support member 20. The second convex portions (b) 45 (b) are fixed to the end portions of the two flat bars 41 fixed at the interval w1 so as to protrude from the end portions. The width w2 of the second convex portion (b) 45 (b) is w2 ≦ w1. The width w3 of the second locking portion 25 of the support member (b) 20 (b) is w3 ≦ w1, and it is preferable that w3 and w1 are substantially equal. Thereby, it is possible to avoid the second locking portion 25 from moving laterally between the two flat bars 41. Similarly, the lateral width w4 of the first locking portion 23 is w4 ≦ w1, and if w4 and w1 are substantially equal, the first locking portion 23 is prevented from laterally moving between the two flat bars 41. be able to. That is, since the first locking portion 23 and the first convex portion 43 are engaged between the two flat bars 41 and the second locking portion 25 and the second convex portion 45 are engaged, The lateral movement of the member 40 on the base 10 can be prevented. It should be noted that the above is the same size and between the two flat bars 41 of the lattice-like object 47 composed of a plurality of flat bars 41, the first convex part 43, the second convex part (a) 45 (a), the first This is a case where the two convex portions (b) 45 (b) are fixed. Shape and number of flat bars 41, first convex portion 43, second convex portion (a) 45 (a), shape of member having second convex portion (b) 45 (b), fixing method, mounting location, etc. Can be changed as appropriate.

  The top surface of the floor member 40 can be appropriately selected according to the purpose of use of the stage. For example, wood such as plywood may be used, or metal such as iron, aluminum, SUS, vinyl chloride, FRP, polypropylene, or other synthetic resin plates or synthetic resin sheets may be used. Moreover, it is not limited to a single layer, A turf panel having a multilayer structure and having artificial turf laminated on the top may be used. An embodiment of a turf panel suitable for golf practice green is shown in FIG. A base member (a) 47 (a) made of cloth, paper or the like is laminated on the top surface of the lattice 47, and a first elastic member 47 (b) made of sponge, non-woven fabric, single ball, polystyrene foam, rubber plate, etc. A second elastic member 47 (c) made of the above, and then an artificial turf 47 (d) are sequentially laminated. Each layer is bonded and fixed with an adhesive. When the stage is assembled with such a turf panel, it can be used as an artificial turf deck instead of a wood deck made of wood installed in the garden, etc., and when it is assembled into a circle, it can be used as a simple golf practice green .

(9) Engagement fixing member The floor member 40 may have a fixing member that fixes the engagement between the first locking portion 23 and the first convex portion 43. 10A, a fixing member 48 for fixing the engagement between the first convex portion 43 and the first locking portion 23 is arranged on the floor member (c) 40 (c) of FIG. 3A. The longitudinal direction longitudinal cross-sectional perspective view of the installed aspect is shown. The floor member (c) 40 (c) is prevented from moving in the direction of the top surface by the engagement of the first convex portion 43 and the first locking portion 23, but can move to the right side in the drawing. It is. Therefore, the fixing member 48 is used to prevent the floor member 40 from moving in the longitudinal direction. When the movement of the floor member (c) 40 (c) is prevented, the movement of the adjacent floor member (b) 40 (b) is prevented, and when the movement of the floor member (b) 40 (b) is prevented, the movement is adjacent. The floor member (a) 40 (a) is prevented from moving. A fixing member 48 shown in FIG. 10 (A) has a handle 48 (a) and a hook 48 (c) fixed at substantially right angles to both ends of a cylindrical shaft 48 (b). The handle 48 (a) and the hook 48 (c) are fixed at the same angle with the cylinder b) as the center of rotation. By sandwiching both ends of the engaging portion between the first locking portion 23 and the first convex portion 43 between the handle 48 (a) and the hook 48 (c), in the longitudinal direction of the floor member (c) 40 (c) Movement is prevented.

  FIG. 10B shows a perspective view of a mode in which the fixing member 48 is attached to the member having the first convex portion 43. The shaft 48 (b) having the hook 48 (c) at the end is inserted into the through hole formed in the back surface of the fixing portion 43 ′ of the first convex portion 43, and the hook 48 (c) is the same as the first convex portion 43. Penetrate to the side. Next, the handle 48 (a) is fixed to the other end of the shaft 48 (b) with a screw or the like. At this time, it is preferable that the handle 48 (a) is fixed so as to be at the same angle as the hook 48 (c) with the central axis of the shaft 48 (b) as the rotation center. Since the handle 48 (a) and the hook 48 (c) at both ends of the shaft 48 (b) face in the same direction such as the bottom surface or the top surface of the floor member 40, the engaging portion is fixed with the hook 48 (c). Rotation due to the dead weight of the handle 48 (a) can be avoided. The length and shape of the shaft 48 (b), the handle 48 (a), and the hook 48 (c) are appropriately selected on the condition that the engagement between the first locking portion 23 and the first convex portion 43 can be fixed. can do.

  FIG. 10C shows a fixing method using the fixing member 48 shown in FIG. 10B, using a partially enlarged view of FIG. 10A. (I) First, the handle 48 (a) is rotated so that the tip of the hook 48 (c) faces the top surface of the floor member (c) 40 (c). (Ii) If the floor member (c) 40 (c) is moved to the floor member (b) 40 (b) side while maintaining this state, the tip of the hook 48 (c) faces the top surface of the floor member 40. And the 1st latching | locking part 23 and the 1st convex part 43 will be in the engaged state. Next, (iii) the handle 48 (a) is rotated so that the tip of the hook 48 (c) faces the bottom surface of the floor member 40. As a result, both ends of the engaging portion between the first convex portion 43 and the first locking portion 23 are held between the handle 48 (a) and the hook 48 (c), thereby preventing the floor member 40 from moving in the longitudinal direction. Is done. The above has been described with the case where the fixing member 48 is attached to the floor member (c) 40 (c), but is not limited thereto. Any mechanism that prevents the floor member (c) 40 (c) from moving in the longitudinal direction during assembly may be used.

(10) Inclining jack mechanism The jack mechanism 27 is used to adjust the height of the pedestal 10, but the inclining jack mechanism 27 is used to incline the assembly-type stage 100 in the longitudinal direction of the floor member 40. Is done. The tilting jack mechanism 27 is configured, for example, so that the pipe-like object 26 shown in FIG. 5A can be tilted. An example of a lateral side view of the tilting jack mechanism 27 is shown in FIG. In FIG. 11, the pipe-like object 26 shown in FIG. 5 is divided into a pipe upper part 26a and a pipe lower part 26b, and a rotating member 27a is mounted between them. The rotating member 27a pivots a rotating member 27a1 inserted into the pipe upper portion 26a, a rotating member 27a2 inserted into the pipe lower portion 26b and capable of fixing the rotating member 27a1, and the rotating member 27a1 and the rotating member 27a2. And a rotating shaft 27a3 to be supported. Further, a protrusion 26a ′ is formed on the pipe upper part 26a, a protrusion 26b ′ is formed on the pipe lower part 26b, and an angle adjusting washer 27b is provided between the protrusions 26a ′ and 26b ′. When the rotation member 27a1 is mounted between the pipe upper part 26a and the pipe lower part 26b, the pipe upper part 26a rotates around the rotation shaft 27a3. The angle between the pipe upper part 26a and the pipe lower part 26b can be arbitrarily set, and can be fixed to a desired angle by the angle adjusting washer 27b.

  FIG. 11 further shows a mode in which a corner portion of the jack base of the jack mechanism 27 rises substantially vertically and a cut is formed in the corner portion to function as the stripe fixing portion 21. A plurality of support members 20 can be connected continuously by inserting the fastening portion 31 of the connecting member 30 shown in FIG. 5C into the cut and connecting the other end to another stripe fixing portion 21.

(11) Threaded jack mechanism If the base 10 is being assembled, the height of the support member 20 can be easily adjusted by rotating the nut handle 27 ′ of the jack mechanism 27. This is because the use of the nut handle 27 ′ at the bottom of the base 10 is easy because there is no floor member 40. On the other hand, a part of the assembly-type stage 100 may be depressed due to variations in the strength of the ground, softening due to rainwater, aging, or the like. In this case, if the floor height of the assembly-type stage 100 is low and the worker cannot dive under the floor, the height cannot be adjusted by rotating the nut handle 27 ', and the floor member 40 and the base 10 are disassembled. Will be forced. Therefore, it is desired to propose a jack mechanism that can be easily adjusted in height without being disassembled. The threaded jack mechanism meets such a demand.

  The screwed jack mechanism includes a fixed base 110 including a base 111 and a columnar portion 113 substantially upright on the base 111, and an extension pipe 120. The extension pipe 120 is a pipe part 121 that covers the columnar part 113, and a rib 123 is formed on at least the upper part of the inner wall, and a screw 129 having a wrench hole 129 'is screwed to the rib 123. The FIG. 12A is a side view of the fixed base 110. The outer diameter of the columnar part 113 is shorter than the inner diameter of the pipe part 121 having the ribs 123 on the inner wall, and a convex part 115 having a shorter diameter is formed on the top of the columnar part 113, and the upper part of the convex part 115 A resin washer 117 is placed on the surface.

  As shown in FIG. 12B, the extension pipe 120 has a lid portion 125 at the upper end of the pipe portion 121, and the lid portion 125 has a structure opened by a through hole 125 ′ for inserting a wrench. Yes. A resin washer 127 having a through hole 127 ′ for inserting a wrench is further attached to the lower portion of the lid portion 125. Further, a screw 129 in which a wrench hole 129 ′ is formed is attached to the lower portion of the resin washer 127 via a thread 123. A hexagonal wrench 130 is inserted as a wrench into the wrench hole 129 ′ through the through hole 125 ′ of the lid 125 and the through hole 127 ′ of the resin washer 127 and rotated to rotate the screw 129. Therefore, the sizes and shapes of the through hole 125 ′ of the lid portion 125, the through hole 127 ′ of the resin washer 127, and the wrench hole 129 ′ are suitable for the above purpose.

  The extension pipe 120 has a structure in which a screw 129, a resin washer 127, and a columnar portion 113 of the fixed base 110 can be inserted from below. Since the inserted screw 129 is attached to the thread 123 formed on the inner wall, the screw 129 and the thread 123 are adjusted to have a shape and size that can be attached to each other. When the fixed base 110 is inserted into the extension pipe 120, the lid 125, the resin washer 127, the screw 129, the resin washer 117, and the columnar part 113 having the convex part 115 are arranged in this order from the upper part to the lower part. When the wrench 130 is inserted through the through-hole 125 ′ of the lid 125 and the screw 129 is rotated to move the rib 123 downward, the distance between the lid 125 and the screw 129 increases, and the expansion pipe 120 is fixed base. Move relative to 110. FIG. 12C is a side view of the screw 129. FIG. The length of the screw 129 is not particularly limited as long as it meets the above purpose.

  FIG. 12B shows an aspect of the extension pipe 120 provided with the pipe portion 121 and a blade 28 ″ shown in FIG. 5A and an insertion portion 29 ′ for inserting the connecting convex portion 29. By providing the wing 28 ″ and the insertion portion 29 ′, the support members 20 can be connected and fixed to each other, and the jack mechanism 27 can be ensured to be inverted substantially vertically. Such an extension pipe 120 is prepared by forming a rib 123 on the inner wall of the pipe-like object 26 of the connecting and fixing member 28 shown in FIG. 5A, and providing a wrench hole 129 'on the lid 26'. be able to. Further, a threaded pipe may be fitted into the inner wall of the pipe-like object 26 constituting the connecting and fixing member 28 shown in FIG. When a ribbed pipe is inserted into the pipe portion 121, the inner diameter of the portion 123 of the elongated pipe 120 becomes narrower than the other portion of the pipe portion 121. In such a case, when the short-diameter convex portion 115 is provided at the top of the columnar portion 113, it can be inserted into the inner wall portion having the ribs 123, so that the stability of the extension pipe 120 and the columnar portion 113 is improved.

  Further, the material of the resin washer 117 and the resin washer 127 is preferably a slidable resin such as polypropylene, silicone, polyamide, polyacetal, fluorinated plastic such as polytetrafluoroethylene, and high molecular weight high density polyethylene. This is to avoid friction during the rotation of the screw 129.

  The extension pipe 120 constituting the threaded jack mechanism is fixed to the bottom surface of the support member 20. For example, the lid 125 of the extension pipe 120 is fixed to the bottom surface of the long plate-like object of the support member 20. When the support member 20 and the extension pipe 120 are weldable materials, they can be integrally formed by welding. At this time, the lid 125 is fixed so that the through hole 125 ′ is secured. Alternatively, a through hole corresponding to the through hole 125 ′ may be formed in the long plate-like object of the support member 20.

  When assembling the pedestal 10 using the support member 20, the floor member 40 placed on the upper part of the through hole 125 'is not cut off or the corresponding through hole so as not to block the through hole 125'. Is formed. FIG. 12B shows a mode in which a semicircular cutout is formed at the end of the floor member 40 as such a through hole. The assembled stage 100 can be viewed through the through-hole 125 '. When a part of the assembly-type stage 100 is depressed due to aging or the like, the hexagon wrench 130 is inserted from the adjacent through hole 125 'and the screw 129 is rotated through the wrench hole 129'. The screw 129 sandwiched between the resin washer 117 and the resin washer 127 moves up and down by rotation along the rib 123. When the screw 129 moves down the rib 123, the fixed base 110 correspondingly moves down, and the support member 20 and the floor member 40 relatively move up. When a part of the assembly type stage 100 is raised, the screw 129 is rotated and moved above the rib 123, and the floor member 40 is relatively moved downward. With this method, the height of a part of the assembly-type stage 100 can be adjusted without disassembling the floor member 40 or the support member 20.

(12) Assembly and Disassembly Method The substantially square assembly type stage 100 shown in FIG. 1 includes six support members (a) 20 (a), six support members (b) 20 (b), and a connecting member 30. Each of the six floor members (a) 40 (a), the floor member (b) 40 (b), the floor member (c) 40 (c), and the floor member (c) 40 (c) Is provided with a fixing member 48 shown in FIG.

  As shown in FIG. 2, a support member (b) is formed in parallel with the row by forming a row in which three support members (a) 20 (a) are connected in the longitudinal direction and positioning with the connecting member 30 as appropriate. Two rows are formed by connecting three 20 (b) in the longitudinal direction, and further, one row is formed by connecting three support members (a) 20 (a) in the longitudinal direction in parallel with the row. Assemble 10. The interval between the support members 20 arranged in parallel is appropriately adjusted according to the positions of the first convex portion 43 and the second convex portion 45 of the floor member 40. By correctly attaching the connecting member 30 whose length and location are determined in advance, the interval between the support members 20 can be easily determined.

  The pedestal 10 uses the standard floor height on the horizontal ground as a reference, and copes with variations in height with the heights of the jack mechanism 27 and the connecting and fixing member 28.

  Next, the floor member (a) 40 (a) is installed on the upper part of the support member (a) 20 (a) and the support member (b) 20 (b) of the base 10. At that time, the protruding direction of the first convex portion 43 of the floor member (a) 40 (a) protrudes in the direction opposite to the opening of the first locking portion 23 of the supporting member (a) 20 (a).

The first convex portion 43 is in the vicinity of the first locking portion 23 of the support member (a) 20 (a), and the second convex portion is in the vicinity of the second locking portion 25 of the adjacent support member (b) 20 (b). Part (a) 45 (a) comes. The floor member (a) 40 (a) is moved in the longitudinal direction so that the first convex portion 43 is formed in the opening portion of the first locking portion 23, and the second convex portion (a ) Insert 45 (a). Thereby, the 1st latching | locking part 23 and the 1st convex part 43 each engage with the 2nd latching | locking part 25 and the 2nd convex part (a) 45 (a).

  Next, the floor member (b) 40 (() is placed on the upper part of the support member (b) 20 (b) and the support member (b) 20 (b) so as to be adjacent to the longitudinal direction of the floor member (a) 40 (a). Install b). In that case, it arrange | positions so that the protrusion direction of 2nd convex part (b) 45 (b) may protrude in the opposite direction to the opening part of the 2nd latching | locking part 25. FIG. When the floor member (b) 40 (b) is moved in the longitudinal direction and brought into contact with the floor member (a) 40 (a), the second protrusion (a) 45 (a) of the floor member (a) 40 (a) is obtained. ) Is inserted into the second convex part (b) 45 (b) of the floor member (b) 40 (b), the second convex part (a) 45 (a) and the second convex part (b) 45. (b) overlaps and engages with the second locking portion 25, and at the same time, the second locking portion (b) 25 (b) of the support member (b) 20 (b) and the floor member (b) 40 (b ) Second convex portion (a) 45 (a) is engaged.

  Next, the floor member (c) 40 (on the upper part of the support member (b) 20 (b) and the support member (a) 20 (a) so as to be adjacent to the longitudinal direction of the floor member (b) 40 (b). Temporarily place c). At this time, the protrusion of the second protrusion (b) 45 (b) of the floor member (c) 40 (c) is arranged to protrude in the direction opposite to the opening of the second locking portion 25. Next, the handle 48 (a) of the fixing member 48 disposed on the floor member (c) 40 (c) is operated so that the tip of the hook 48 (c) is directed to the top surface of the floor member (c) 40 (c). Rotate to When the floor member (c) 40 (c) is moved in the longitudinal direction and its end is brought into contact with the end of the floor member (b) 40 (b), the second protrusion of the floor member (b) 40 (b) The second convex part (b) 45 (b) of the floor member (c) 40 (c) is inserted into the lower part of the part (a) 45 (a), and the second convex part (a) 45 (a) and the second convex part (a) 45 (a) Two convex portions (b) 45 (b) overlap and engage with the second locking portion 25, and at the same time, the first locking portion 23 of the support member (a) 20 (a) and the floor member (c) 40 ( The first convex portion 43 of c) is engaged. Thereafter, the handle 48 (a) is operated to rotate so that the tip of the hook 48 (c) faces the bottom surface of the floor member 40, and the engaging portion between the first locking portion 23 and the first convex portion 43 is fixed. To do.

  When assembling, floor members (a) 40 (a) → floor members (b) 40 (b) → floor members (c) 40 (c) are installed in this order. This order is sufficient. Therefore, after all the floor members (a) 40 (a) are installed and engaged, all the floor members (b) 40 (b) are installed and engaged, and then all the floor members (c) 40 ( c) is not limited to erection and engagement. According to the above order, the overlapping of the second convex portion (a) 45 (a) and the second locking portion (b) 45 (b) at the end of the adjacent floor member 40 and the second locking portion 25. Can be easily engaged.

  In the assembly type stage 100 of the present invention, one floor member 40 is engaged with the support member 20 at two locations, and the second convex portions 45 at the ends of the floor members 40 adjacent to each other in the longitudinal direction overlap each other. Since the second engaging portion 25 of the support member 20 is engaged, the end of the floor member 40 does not lift even when a load is applied to an arbitrary position of the assembly type stage 100. In particular, if the floor member (c) 40 (c) that is finally engaged with the support member 20 is prevented from moving in the longitudinal direction, any floor member 40 does not move in the longitudinal direction, and the assembly stage 100 Is stable.

  The dismantling may be performed in the reverse order. When the handle 48 (a) of the floor member (c) 40 (c) is rotated so that the tip of the hook 48 (c) faces the top surface of the floor member (c) 40 (c), the floor member (c) ) 40 (c) can be pulled out in the longitudinal direction. Next, the adjacent floor member (b) 40 (b) and floor member (a) 40 (a) are sequentially pulled out.

(13) Application In addition to the substantially square assembly-type stage 100, a substantially circular assembly-type stage 100 having an inclination can be assembled. Further, the floor member 40 may be a laminate of artificial grass on the top surface. FIG. 13 shows a substantially circular assembly-type stage 100 that is highly inclined from the lower left to the upper right of the drawing. Artificial grass is laminated on the top, a pole 90 is erected in the center, and a ball exclusion rod 93 that removes the ball from the assembling stage 100 by rotation is arranged with a rotating device 95 and used as a golf practice green It is an aspect. In order to assemble the pedestal 10 so as to increase from the lower left to the upper right of the drawing, the support member 20 having a different height is used in advance, or the inclination jack mechanism 27 is provided to ensure the height and inclination of the pedestal 10.

Finally, the ball exclusion rod 93 and the rotating device 95 are disposed, and the pole 90 is erected. The ball exclusion rod 93 is a mechanism for rotating the surface of the assembly-type stage 100 by the rotation device 95 to eliminate the ball (not shown). The rotating device 95 provided at the upper part of the assembly type stage 100 does not impair the shape of the ground.

  The assembly-type stage 100 includes at least a floor member (a) 40 (a) having the first convex portion 43 and the second convex portion (a) 45 (a), a first convex portion 43, and a second convex portion. (B) A floor member (c) 40 (c) having 45 (b) may be provided. The smallest assembly stage 100 includes one floor member (a) 40 (a) and one floor member (c) 40 (c), and two support members (a) 20 (a) and one support member. (B) It can be composed of 20 (b). In the assembly, the support member (a) 20 (a), the support member (b) 20 (b), and the support member (a) 20 (a) are arranged in parallel. At that time, the pedestal 10 may be assembled by positioning by attaching the connecting member 30. Next, the support member 20 is constructed and engaged in the order of the floor member (a) 40 (a) → the floor member (c) 40 (c). When the floor member (c) 40 (c) has the fixing member 48, the engagement between the first locking portion 23 and the first convex portion 43 is fixed by the fixing member 48, and the floor member (c) 40 (c ) Is prevented from moving in the longitudinal direction. In order to increase the size of the assembly type stage 100 in the longitudinal direction, the number of floor members (b) 40 (b) and support members (b) 20 (b) may be increased. In order to increase the size in the width direction, the supporting member 20 is connected and fixed by the connecting and fixing member 28, and the number of floor members 40 is increased.

  In FIG. 13, the floor member 40 having artificial turf laminated on the upper surface is used. However, the floor member 40 may be used as a grating without being laminated on the top surface of the lattice-like object 47. In that case, according to a use, you may coat | cover a floor member with a vinyl sheet, fluff, etc., and use it as a stage. In addition, it is possible to appropriately change the detailed configuration within the scope of the gist of the present invention.
