Embodiments of the present invention will be described with reference to the drawings.
The connection structure of the assembling type shelf according to the present embodiment is for bridging and fixing the cross members between the pipe-shaped support columns 50. For example, although not particularly shown, four pillars 50 are erected vertically on the floor surface, and a long material such as the horizontal pipe 40 is bridged between the adjacent pillars 50 to form an assembling shelf. When the horizontal pipe 40 is used as the horizontal member, the horizontal pipe 40 may be used for suspending a hanger, may be used for attaching a shelf plate, or may be used simply for reinforcement. .. Although the horizontal pipe 40 is used as the horizontal member in the present embodiment, the type and shape of the horizontal member are not particularly limited. Instead of the horizontal pipe 40, a horizontal member having another shape (square member, angle member, shelf plate itself) may be used.
The fittings 10 as shown in FIG. 1 are attached to both ends of the horizontal pipe 40. The fixture 10 is for attaching the horizontal pipe 40 to the support column 50.

As shown in FIG. 6, a plurality of hook holes 51 are formed at predetermined intervals in the longitudinal direction on the side surface of the support column 50 according to the present embodiment. The hook hole 51 is a vertically long rectangular hole, and is formed through the peripheral wall of the support column 50 to hook the hook 13a of the fixture 10 described later. In this embodiment, a plurality of hooking holes 51 (at least two, and a maximum of four hooking holes 51) are formed at 90 degrees in the circumferential direction of the support column 50. For this reason, it is possible to attach a plurality of fixtures 10 (at least two, and a maximum of four fixtures 10) at the same height by 90 degrees with respect to one column 50.
The fixture 10 according to the present embodiment includes a base member 11, a spring 12, and a retaining member 13.

The base member 11 is a bottomed cylindrical member attached so as to cover the end of the horizontal pipe 40. As shown in FIG. 2, the base member 11 is a metal component including a cylindrical tubular portion 11a and a mounting surface 11b forming the bottom surface of the tubular portion 11a. The inner diameter of the tubular portion 11a is formed so that the tip portion of the horizontal pipe 40 can be inserted therein. When the base member 11 is attached to the horizontal pipe 40, the tip end of the horizontal pipe 40 is inserted through the opening of the tubular portion 11a, and the both are pressure-bonded to couple the base member 11 and the horizontal pipe 40 together. A mounting hole 11c for mounting the locking member 13 is formed through the mounting surface 11b.

The spring 12 is a leaf spring as shown in FIG. The spring 12 is formed by bending a flat metal plate, and includes a central portion 12a and pressing portions 12c provided on both sides of the central portion 12a. A through hole 12b used for attaching the spring 12 is formed in the central portion 12a. The pressing portions 12c on both sides are formed symmetrically, and project obliquely from both sides of the central portion 12a.

The locking member 13 is a metal plate-shaped member that is inserted into the locking hole 51 of the support column 50 and hooked therein. As shown in FIG. 4, the hooking member 13 includes a hook 13a inserted into the hooking hole 51 and an insertion portion 13b inserted into the mounting hole 11c of the base member 11. The insertion portion 13b is provided so as to project from the vicinity of the upper end portion of the hook 13a at substantially right angles to the hook 13a. Further, an engaging portion 13c is provided near the base of the insertion portion 13b by forming a step so as to project above and below the insertion portion 13b. The engagement portion 13c is a portion that is abutted without passing through the mounting hole 11c when the insertion portion 13b is inserted into the mounting hole 11c of the base member 11. By the abutting of the engaging portion 13c in this manner, as shown in FIG. 5B, a predetermined gap G is formed between the inner side surface of the hook 13a and the mounting surface 11b.

The spring 12 and the latch member 13 described above are attached to the base member 11 as shown in FIG. That is, the insertion portion 13b of the retaining member 13 is passed through the through hole 12b of the spring 12 and further through the mounting hole 11c of the base member 11. At this time, the pressing portion 12c of the spring 12 is attached so as to project toward the tip of the lateral pipe 40. At this time, the engaging portion 13c of the retaining member 13 is wider than the through hole 12b of the spring 12 and the mounting hole 11c of the base member 11, and does not penetrate these holes. Therefore, when the insertion portion 13b is inserted all the way, the engagement portion 13c sandwiches the central portion 12a of the spring 12 and abuts against the mounting surface 11b of the base member 11. In other words, the central portion 12a of the spring 12 is sandwiched and held by the engaging portion 13c of the latch member 13 and the mounting surface 11b of the base member 11. In this state, the tip of the insertion portion 13b penetrating the spring 12 and the base member 11 is caulked to join the three members. As a result, the fixture 10 as shown in FIG. 5B is formed.

The attachment 10 can be attached to and detached from the horizontal pipe 40 as shown in FIG. As shown in FIG. 6A, the fixture 10 is formed so that a gap G is formed between the inner surface of the hook 13a and the central portion 12a of the spring 12. The width of the gap G is formed to be larger than the thickness of the peripheral wall of the support column 50, and the peripheral wall of the support column 50 can be inserted into the gap G. Further, on both sides of this gap G, the pressing portions 12c of the springs 12 project in the tip direction. Therefore, when the peripheral wall of the column 50 is inserted into the gap G, the pressing portions 12c on both sides come into contact with and press the surface of the column 50.

When the attachment 10 is attached to the support column 50, as shown in FIG. 6, it is only necessary to hook the hook 13 a of the retaining member 13 into the retaining hole 51 of the support column 50. When hooked in this way, as shown in FIG. 7, the holding portions 12c of the spring 12 come into contact with the surface of the support column 50 on both sides of the locking hole 51 and press the surface of the support column 50. When the spring 12 presses the surface of the support column 50 in this way, the attachment 10 (hook 13a) is attracted in the direction opposite to the tip of the lateral pipe 40 (rightward in FIG. 6) by the reaction of this pressing. By pulling the hook 13a in this manner, the peripheral wall of the support column 50 is elastically sandwiched by the hook 13a and the spring 12, so that the fixture 10 can be firmly fixed to the support column 50.

As described above, according to the present embodiment, the attachment tool 10 that is attachable to and detachable from the support column 50 includes the hooking member 13 that is inserted into the hooking hole 51 and is hooked, and the hooking member 13 is hooked to the hooking hole 51. And a spring 12 that acts so as to pull the hooking member 13 when the hooking member 13 is pulled. Therefore, since the spring 12 acts only by hooking the hooking member 13 in the hooking hole 51, the horizontal pipe 40 can be firmly fixed without using an assembling screw or an adjusting screw. It is possible to prevent rolling and rolling. Also, when disassembling the assembly-type shelf, it is only necessary to remove the locking member 13 from the locking hole 51, so that the work is easy and parts such as screws are not lost.

The spring 12 is a leaf spring that comes into contact with the support column 50 on both sides of the locking hole 51 when the locking member 13 is hooked in the locking hole 51. Therefore, the inclination of the fixture 10 can be suppressed by the leaf springs that come into contact with each other on both sides of the support column 50, so that rattling and rolling can be effectively prevented.

Further, the attachment 10 includes a base member 11 to which a latch member 13 and a spring 12 are attached, and the spring 12 is fixed to the base member 11 by being sandwiched between the latch member 13 and the base member 11. According to such a configuration, since no new part or processing for fixing the spring 12 is required, the manufacturing cost can be suppressed.

(Modification 1)
Instead of the fixture 10 as described above, or in addition to the fixture 10 as described above, a fixture 20 as shown in FIGS. 8 and 9 may be used.
As shown in FIG. 8, the attachment 20 includes a spring 21 and a hook member 22.

The spring 21 is a leaf spring similar to the spring 12 described in FIG. That is, the spring 21 is formed by bending a flat metal plate, and includes a central portion 21a and pressing portions 21c provided on both sides of the central portion 21a. A through hole 21b used for attaching the spring 21 is formed in the central portion 21a. The pressing portions 21c on both sides are formed symmetrically, and project obliquely from both ends of the central portion 21a.

The hook member 22 is a metal plate-shaped member that is inserted into the hook hole 51 of the support column 50 and hooked. The locking member 22 includes an upper hook 22a and a lower hook 22b that are inserted into the locking hole 51, and a spring mounting portion 22c for mounting the spring 21. The upper hook 22a and the lower hook 22b are vertically arranged side by side with a predetermined interval. The arrangement interval of the upper hook 22a and the lower hook 22b is set to be equal to the arrangement interval of the hook holes 51 of the support column 50. Therefore, the upper hook 22a and the lower hook 22b are formed so as to be simultaneously hooked in the two hook holes 51 arranged in parallel in the longitudinal direction of the column 50 (see FIG. 8B).

The spring attachment portion 22c is a protrusion provided between the upper hook 22a and the lower hook 22b. When attaching the spring 21 to the retaining member 22, as shown in FIG. 9, the spring mounting portion 22c is penetrated through the through hole 21b of the spring 21, and the spring 21 is fixed by caulking the tip of the spring mounting portion 22c.

A shelf board support portion 23 is attached to the hooking member 22 according to the present embodiment. The shelf support portion 23 is a metal piece fixed to the upper surface of the hanging member 22. The shelf support portion 23 is fixed so that its upper surface is horizontal, and the upper surface can support the shelf board. In the present embodiment, a plurality of shelf plate support portions 23 are attached to the hanging member 22.

When attaching the fixture 20 to the support column 50, as shown in FIG. 8, it suffices to hook the upper hook 22a and the lower hook 22b of the retaining member 22 into the retaining holes 51 of the support column 50. When the hook is hooked, as shown in FIG. 8, the pressing portion 21c of the spring 21 contacts the surface of the column 50 between the upper hook 22a and the lower hook 22b, and presses the surface of the column 50. When the spring 21 presses the surface of the support column 50 in this way, the latching member 22 is attracted to the right in FIG. 8 by the reaction of this pressing. Therefore, since the upper hook 22a and the lower hook 22b are attracted, the peripheral wall of the column 50 is elastically sandwiched by the upper hook 22a and the lower hook 22b and the spring 21, so that the fixture 20 is firmly fixed to the column 50. be able to.

As described above, according to the present modification, the attachment tool 20 that is attachable to and detachable from the support column 50 includes the hooking member 22 that is inserted into the hooking hole 51 and is hooked, and the hooking member 22 is hooked to the hooking hole 51. And a spring 21 that acts so as to pull the hooking member 22 when it is opened. Therefore, since the spring 21 acts only by hooking the hooking member 22 in the hooking hole 51, it is possible to firmly fix the fixture 20 without using an assembly screw, an adjusting screw, or the like. It is possible to prevent rolling and rolling. Also, when disassembling the assembly-type shelf, it is only necessary to remove the hooking member 22 from the hooking hole 51, so that the work is easy and parts such as screws are not lost.

Further, the fixture 20 includes at least two hooks (upper hook 22a and lower hook 22b) arranged above and below to be hooked in the hooking hole 51, and the spring 12 is a hooking member between the two hooks. It is attached to 22. With such a configuration, the shelf plate and the like can be stably supported by the two hooks. Further, since the spring 21 provided between the two hooks suppresses the rattling of the two hooks, it is possible to prevent rattling and rolling even without using a plurality of springs 21. Although the fixture 20 according to the present embodiment has two hooks, it goes without saying that it may have three or more hooks.

(Modification 2)
Instead of the fixture 10 or the fixture 20 as described above, or in addition to the fixture 10 or the fixture 20 as described above, a fixture 30 as shown in FIGS. 10 and 11 may be used. ..
The attachment 30 includes a base member 31, a spring 32, and a hooking member 33.

The base member 31 is a bottomed cylindrical member attached so as to cover the end of the horizontal pipe 40. As shown in FIG. 10, the base member 31 is a metal component including a cylindrical tubular portion 31a and a mounting surface 31b forming the bottom surface of the tubular portion 31a. The inner diameter of the tubular portion 31a is formed so that the tip portion of the horizontal pipe 40 can be inserted therein. When the base member 31 is attached to the horizontal pipe 40, the tip end of the horizontal pipe 40 is inserted from the opening of the tubular portion 31a, and the both are pressure-bonded, so that the base member 31 and the horizontal pipe 40 are joined. A mounting hole 31c for mounting the locking member 33 is formed through the mounting surface 31b. Further, as shown in FIG. 11, the mounting surface 31b is formed with a concave portion 31d that is depressed in an arc shape. The recessed portion 31d is formed in an arc shape having a diameter equal to the outer diameter of the support column 50 so as to be in close contact with the outer peripheral surface of the support column 50 when the fixture 30 is attached to the support column 50.

The spring 32 is a leaf spring similar to the spring 12 described in FIG. That is, the spring 32 is formed by bending a flat metal plate, and includes a central portion 32a and pressing portions 32c provided on both sides of the central portion 32a. A through hole 32b used for attaching the spring 32 is formed in the central portion 32a. The pressing portions 32c on both sides are formed symmetrically, and project obliquely from both ends of the central portion 32a.

The hooking member 33 is a metal plate-shaped member that is inserted into the hooking hole 51 of the column 50 and hooked therein. The locking member 33 includes a hook 33a inserted into the locking hole 51 and an insertion portion 33b inserted into the mounting hole 31c of the base member 31. The insertion portion 33b is provided so as to project from the vicinity of the upper end portion of the hook 33a at substantially right angles to the hook 33a. An engaging portion 33c is formed near the base of the insertion portion 33b by forming a step so as to project above and below the insertion portion 33b. The engagement portion 33c is a portion that is abutted against the attachment surface 31b of the base member 31 when the insertion portion 33b is inserted into the attachment hole 31c of the base member 31, and the engagement portion 33c abuts in this way. A predetermined gap G is formed between the inner surface of the hook 33a and the mounting surface 31b.

The spring 32 and the hooking member 33 described above are attached to the base member 31 as shown in FIG. That is, the insertion portion 33b of the latch member 33 is penetrated through the mounting hole 31c of the base member 31 and further through the through hole 32b of the spring 32. At this time, the pressing portion 32c of the spring 32 is attached so as to project in the front end direction (the direction in which it abuts the back surface of the base member 31). Further, since the engaging portion 33c of the hooking member 33 is wider than the inserting portion 33b, it does not penetrate the mounting hole 31c of the base member 31. Therefore, when the insertion portion 33b is inserted all the way, the engagement portion 33c abuts against the mounting surface 31b of the base member 31. In this state, the tip of the insertion portion 33b penetrating the base member 31 and the spring 32 is caulked to join the three members. When crimping the tip of the insertion portion 33b, the spring 32 is not completely crushed, but a play is provided so that the spring 32 can elastically deform. Accordingly, the latch member 33 is slidably attached to the base member 31 in parallel with the biasing direction of the spring 32. As described above, the fixture 30 as shown in FIG. 10B is formed.

The fixture 30 is used by being attached to the horizontal pipe 40 as shown in FIG. As shown in FIG. 10B, the attachment 30 is formed such that a gap G is formed between the inner surface of the hook 33a and the central portion 32a of the spring 32. The peripheral wall of the support column 50 can be inserted into this gap G. Although the width of the gap G is formed to be smaller than the thickness of the peripheral wall of the support column 50 in a natural state, the latch member 33 is slid with respect to the base member 31 against the biasing force of the spring 32. Then, the width of the gap G can be increased. Since the width of the gap G can be made larger than the thickness of the peripheral wall of the support column 50, the peripheral wall of the support column 50 can be inserted into the gap G.

When the attachment 30 is attached to the support column 50, the hook 33a of the retaining member 33 only has to be hooked in the retaining hole 51 of the support column 50. When hooked in this manner, as shown in FIG. 11B, the spring 32 attracts the hook 33a of the hooking member 33, whereby the hook 33a and the recessed portion 31d of the base member 31 elastically deform the peripheral wall of the column 50. Since it is sandwiched between them, the fixture 30 can be firmly fixed to the column 50.

As described above, according to the present modification, the attachment tool 30 that is attachable to and detachable from the support column 50 includes the hooking member 33 that is inserted into the hooking hole 51 and is hooked, and the hooking member 33 is hooked to the hooking hole 51. And a spring 32 that acts so as to pull the hooking member 33 when the hooking member 33 is pulled. Therefore, since the spring 32 acts only by hooking the hooking member 33 in the hooking hole 51, the horizontal pipe 40 can be firmly fixed without using screws for assembly, adjusting screws, etc. It is possible to prevent rolling and rolling. Further, even when disassembling the assembling type shelf, since it is only necessary to remove the hooking member 33 from the hooking hole 51, the work is easy, and parts such as screws are not lost.

Further, the attachment 30 includes a base member 31 that slidably supports the latching member 33 in parallel with the biasing direction of the spring 32, and the spring 32 causes the hook 33 a of the latching member 33 to move in the direction of the base member 31. It is urged to attract to. With such a configuration, the peripheral wall of the support column 50 can be sandwiched and held by the hook 33a and the base member 31, so that rattling and rolling can be effectively prevented.
