It is a sectional view of a part of the support structure. It is a perspective view of the same support structure.

Hereinafter, a first embodiment of a support structure according to the present invention will be described with reference to the accompanying drawings. However, the present invention is not limited to this embodiment.

As shown in FIG. 1, a fixture 1 including a support structure A according to the first embodiment of the present invention is a so-called shelf, and can store books and the like. The fixture 1 includes a bottom part 2 disposed on a floor surface F, a support structure 3 supported by the bottom part 2 and extending in the vertical direction UP, a bracket 4 supported by the support structure 3, and a support structure 3 supported by the bracket 4. The support structure 3 includes a shelf board 5 which is a supported object, and an upper frame 6 provided on the upper part of the support structure 3.

Here, the normal direction of the floor surface F on which the fixture 1 is installed is the up-down direction (arrow UP is upward), and the directions orthogonal to the up-down direction are the front-rear direction (arrow FR is forward) and the left-right direction (arrow LH is forward), respectively. left side).

The support structure 3 has a structure capable of supporting the load of the bracket 4, the shelf board 5, and the objects stored in the shelf board 5, such as books. In this embodiment, the support structure 3 is composed of a plurality of pillars 3A. In this embodiment, the pillars 3A are arranged at four corners of the bottom portion 2 formed in a rectangular shape. The upper frame 6 is formed in a rectangular frame shape corresponding to the pillars 3A, and connects the upper ends of the four pillars 3A. Note that the arrangement of the pillars 3A is not limited to being arranged at the four corners of a rectangle, but may be arranged at the corners of a polygon or on the circumference.

As shown in FIGS. 1 and 2, each support column 3A of this embodiment has a rectangular tube shape in which a space communicating in the vertical direction UP is formed. Note that the support column 3A may have a shape such as a rectangular column, a cylinder, or a circular column, as long as it functions as a column. The support column 3A is made of, for example, a material such as metal. Furthermore, in this embodiment, two struts 3A lined up in the front-rear direction FR form a set, and two sets are arranged in the left-right direction LH. The brackets 4 are provided on both sides in the left-right direction LH in correspondence with each set of struts 3A. The bracket 4 is supported by the support surface 3a, with the surface on the inside in the left-right direction LH where the sets of struts 3A face each other serving as a support surface 3a. The shelf board 5 is supported by brackets 4 at both edges in the left-right direction LH.

As shown in FIG. 2, each support column 3A has an insertion hole 3b that opens to the support surface 3a, a connection hole 3c that is provided above the insertion hole 3b and opens to the support surface 3a, and a support structure. It has a hollow part 3d that communicates the insertion hole 3b and the connection hole 3c inside the support column 3A constituting the support 3. The connection hole 3c is provided at a position lower than the upper surface 5a of the shelf board 5 when the shelf board 5 is placed on the mounting surface 4p. Further, as shown in FIG. 1, the connection hole 3c is provided at a position inside the front end 5b and rear end 5c of the shelf board 5 in the front-rear direction FR. That is, as shown in FIG. 4, the connection hole 3c is covered by a shelf board 5, which is a supported object supported by the bracket 4. The hollow portion 3d is formed by a part of the internal space extending in the vertical direction UP inside the support column 3A. In other words, the hollow portion 3d is surrounded by the inner surface 3e of the support column 3A. A plurality of sets of the insertion hole 3b, the connection hole 3c, and the hollow part 3d are formed in the vertical direction UP so that the installation heights of each support 3A are the same.

The bracket 4 includes a mounting section 4a on which the shelf board 5 is mounted, a connecting piece 4b fixed to the support column 3A forming the support structure 3, and a return section 4c. The mounting portion 4a is formed in a plate shape extending in the front-rear direction FR, and is curved outward in the front-rear direction FR so that both ends thereof face each support column 3A. The upper surface of the placing portion 4a functions as a placing surface 4p on which the shelf board 5, which is the object to be supported, is placed. A pair of connecting pieces 4b are provided at the ends of the mounting portion 4a so as to correspond to the two supporting columns 3A forming the set. The connecting piece 4b is formed into a plate shape, and is bent from the mounting portion 4a and extends upward. A pair of return portions 4c are provided at the ends of the mounting portion 4a so as to correspond to the two pillars 3A and the pair of connection pieces 4b forming the set. The return portion 4c is formed in a plate shape, and is bent from the placing portion 4a and extends downward. The return portion 4c is provided to be shifted from the corresponding connection piece 4b in the front-rear direction FR. Such a bracket 4 can be made by making cuts at both ends of a plate-shaped member, for example, at the boundary between the connecting piece 4b and the barbed part 4c, so that the part that will become the connecting piece 4b is moved upward, and the part that will be the barbed part 4c is cut upward. It can be formed by bending it downward. The height 4h from the lower surface 4q of the mounting part 4a to the upper end of the connecting piece 4b is such that the lower surface 4q of the mounting part 4a is in contact with at least the lower end of the insertion hole 3b, and the connecting hole 3c corresponding to the insertion hole 3b is The dimensions are such that it can be covered within the hollow portion 3d and that the connecting piece 4b can be taken in and out from the insertion hole 3b. Moreover, the lower end of the barbed portion 4c has a dimension that does not reach the lower end of the insertion hole 3b when the upper surface (placing surface 4p) of the mounting portion 4a is in contact with the upper end of the insertion hole 3b.

In such a bracket 4, the connecting piece 4b of the bracket 4 is fixed to the support column 3A through the connecting hole 3c. For example, in the bracket 4, the support 3A and the connecting piece 4b are welded together at the peripheral edge of the connecting hole 3c. When the shelf board 5 is placed on the placing part 4a, a moment is generated in the placing part 4a due to the load of the shelf board 5 and the articles placed on the shelf board 5, but the connecting piece 4b This can be resisted by the moment generated by the reaction force received from the inner surface 3e, and thereby the load caused by the shelf board 5 and the articles placed on the shelf board 5 can be supported. That is, the bracket 4 having the mounting part 4a on which the shelf board 5 is mounted, the insertion hole 3b, the connection hole 3c, and the hollow part 3d provided for attaching the bracket 4 to the support surface 3a are the same as those in this embodiment. The support structure 3 having the support surface 3a extending in the vertical direction UP constitutes a support structure A that supports the shelf board 5, which is an object to be supported.

Such a support structure A can be realized by attaching the bracket 4 as follows.
That is, first, the insertion hole 3b and the connection hole 3c are formed in the support surface 3a of the support column 3A constituting the support structure 3, and communicated through the hollow part 3d (hole formation step). Next, the bracket 4 having the mounting portion 4a and the connecting piece 4b is formed by bending the plate material (bracket forming step). In addition, in this embodiment, a return portion 4c is further formed. Next, the connecting piece 4b of the bracket 4 is inserted into the insertion hole 3b formed at a height corresponding to the height at which the shelf board 5 is installed. Then, by lifting the placement part 4a of the bracket 4, the barbed part 4c is also inserted into the insertion hole 3b, and the connection piece 4b and barbed part 4c are arranged in the hollow part 3d. Next, by moving the mounting part 4a downward until its lower surface 4q contacts the lower end of the insertion hole 3b, the connection piece 4b covers the connection hole 3c while contacting the inner surface 3e of the support column 3A, that is, the connection hole The connecting piece 4b can be exposed from the outside of the bracket 3c (bracket arrangement step). Furthermore, the return portion 4c can be brought into contact with the lower side of the insertion hole 3b on the inner surface 3e of the support column 3A. In each support column 3A, the connection piece 4b and the return portion 4c are similarly installed at the positions where the corresponding insertion hole 3b and connection hole 3c are formed. Then, the support 3A and the bracket 4 can be fixed by welding the peripheral edge of the connection piece 4b of the support 3A to the connection piece 4b at the portion of the connection piece 4b exposed to the outside of the support 3A from the connection hole 3c. fixed process).

At this time, the return portion 4c is in contact with the inner surface 3e of the column 3A and is locked to the column 3A inside the hollow portion 3d so that it cannot move toward the opening side of the insertion hole 3b. It is possible to prevent the inserted connection piece 4b from slipping out of the insertion hole 3b and the bracket 4 from falling off the support column 3A. Then, the connection piece 4b of the bracket 4 is fixed to the support column 3A through the connection hole 3c, so that the bracket 4 is supported by the support column 3A. When the shelf board 5 is placed on the placing part 4a in this state, a downward force is generated on the placing part 4a due to the load of the shelf board 5 and the articles placed on the shelf board 5. The force can be resisted by fixing the connecting piece 4b and the support column 3A in the connecting hole 3c. Further, the moment generated by the above-mentioned downward force can be resisted by the moment generated by the reaction force that the connecting piece 4b receives from the inner surface 3e of the support column 3A. can support loads due to

As described above, according to the support structure A of the present embodiment and the fixture 1 including the support structure A, the support structure 3 extends from the placement part 4a on which the shelf board 5, which is the object to be supported, is placed. Since the connecting piece 4b to be connected extends upward from the insertion hole 3b through the hollow portion 3d, it can be fixed to the supporting structure 3 from the outside through the connecting hole 3c while not being exposed to the outside of the supporting structure 3. I can do it. When the shelf board 5 is placed on the mounting part 4a of the bracket 4, the connection hole 3c is provided in a position covered by the shelf board 5, so that the connection piece 4b is fixed in the connection hole 3c by welding. The exposed parts are not exposed to the outside and the aesthetics are not compromised. In addition, although a moment is generated due to the load applied from the shelf board 5 to the mounting part 4a of the bracket 4, the connecting piece 4b extends upward with respect to the mounting part 4a and is disposed inside the support structure 3. , the connecting piece 4b can resist the above-mentioned moment by a reaction force from the wall surface forming the hollow portion 3d in the support structure 3. Thereby, the load caused by the shelf board 5 and the articles placed on the shelf board 5 can be supported reliably.

Further, the return portion 4c is locked to the support structure 3 inside the hollow portion 3d so as to be immovable toward the opening side of the insertion hole 3b, so that the connecting piece 4b inserted into the insertion hole 3b can be inserted into the insertion hole. It is possible to prevent the bracket 4 from slipping out from the support structure 3 and falling off from the support structure 3.

Although the embodiment of the present invention has been described in detail with reference to the drawings above, the specific configuration is not limited to this embodiment, and includes changes and combinations of the configuration without departing from the gist of the present invention. It will be done.

In this embodiment, the support structure 3 is constituted by the support column 3A, but is not limited thereto. For example, the support structure 3 may be a wall extending in the front-rear direction FR. In this case, a pair of insertion holes 3b, connection holes 3c, and hollow parts 3d are formed in the wall body at the same height in correspondence with the pair of connection pieces 4b provided at both ends of the mounting part 4a of the bracket 4. They may also be provided in pairs. Note that the hollow portions 3d of each group do not need to communicate with each other. Furthermore, although the connecting piece 4b is fixed by welding to the peripheral edge of the connecting hole 3c, the present invention is not limited to this. For example, by providing a screw hole in the connecting piece 4b, inserting a screw from the outside of the connecting hole 3c, and tightening the screw into the screw hole provided in the connecting piece 4b, the connecting piece 4b is moved to the position of the connecting hole 3c. It may also be fixed to the support structure 3.

Further, in the present embodiment, the bracket 4 includes a pair of connecting pieces 4b, and is fixed to the support structure 3 at two locations by these connecting pieces 4b, but the present invention is not limited to this. For example, there may be three or more locations. Moreover, one connection piece 4b may be fixed to the support structure 3 as long as it can support the load applied from the supported object.

Further, in this embodiment, the shelf board 5 is taken as an example of the supported object supported by the bracket 4, but the object is not limited to this. For example, it may be possible to support horizontal bars that are passed between the pillars 4 and from which articles can be suspended. Further, for example, it may be used to support a lighting fixture provided in a fixture. At least, it is a component or device that is provided as a component of a fixture and supported by a bracket, and is applicable to various supported objects as long as it covers the connection hole 3c by being supported by the bracket 4. .
