Description

  The present invention relates to a connection reinforcing tool that reinforces the connection between a side plate and a back plate in a storage unit having an open bottom side.

  Since this type of storage unit does not have a bottom plate, the structure is reinforced by connecting the opposing side plates with a crosspiece at the rear end. Even in this case, when the hinged door opens and closes, the side plate to which the hinged door is attached may swing left and right. That is, in such a structure, the corner angle between the side plate and the back plate tends to fluctuate in the lower part.

  For this reason, this type of storage unit requires a reinforcing structure that hardly causes the side plate to sway as described above. Conventionally, various L-shaped metal fittings have been proposed as a connecting reinforcement between the side plate and the back plate. (For example, refer to Patent Document 1).

  In the L-shaped metal fitting of this document, an L-shaped horizontal plate piece is applied to the lower end of the connecting corner portion of the side plate and the back plate, and a fixed piece bent upward from the horizontal plate piece is provided inside each of the side plate and the back plate. It is fixed with screws or the like so as to be along the plate surface.

JP 2011-103989 A

  However, the L-shaped metal fitting of Patent Document 1 does not have a shape that is applied directly to the corner between the side plate and the back plate to prevent the angle from changing. Therefore, even if this L-shaped metal fitting is used, it cannot be a complete measure for preventing the side plate from shaking. In addition, since this is a structure in which the L-shaped metal fitting is fixed to the lower end of the side plate and the back plate, the lower end surface is uneven, and when it is installed so as to be installed directly on the floor surface, there is rattling. It will occur.

  Furthermore, the general L-shaped bracket as shown in FIG. 5 of the same document is directly applied to the corner between the side plate and the back plate, but it is simply a bent plate material in the first place. Because of the structure, the thickness is small, and that alone is not sufficient as a measure to strengthen rigidity.

  The present invention has been proposed in view of such circumstances, and its purpose is to firmly connect the side plate and the back plate in the lower part so as to suppress fluctuations in the corner angle as much as possible. An object of the present invention is to provide a connection reinforcing tool capable of improving the rigidity of the joint.

  In order to achieve the above-mentioned object, the connection reinforcing tool of the present invention has at least a pair of side plates, a back plate, and a crosspiece disposed under the back plate and connecting the opposing side plates, and the bottom side is open. The connection reinforcing tool for reinforcing the connection between the side plate and the back plate in the storage unit is provided with a first horizontal piece arranged to protrude from the plate surface of the side plate, and to protrude from the plate surface of the pier. The second horizontal piece is integrated with the L-shaped horizontal plate piece in plan view, and the first horizontal piece is bent at the first fixed piece fixed to the plate surface of the side plate, The second horizontal piece is extended and a second fixed piece fixed to the board surface of the pier is bent and extended.

  According to the connection reinforcing tool of the present invention, since it has the above-described configuration, the side plate and the back plate can be firmly connected so as to suppress the variation in the corner angle as much as possible, thereby improving the rigidity of the storage unit. Can be made.

It is a cross-sectional view (those cut | disconnected according to the upper end surface of a pier) which shows the other example of installation aspects of a storage unit.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. 1-4 is explanatory drawing of the connection reinforcement tool 10 which concerns on this embodiment. FIG. 4 is a view showing another installation mode example of the storage unit 20 shown in FIG.

  In the following embodiments, directions such as up and down, left and right, front and rear are determined based on the state in which the storage unit 20 to which the connection reinforcing tool 10 is attached is attached to the wall surface 1, and the shelf plate 26 of the storage unit 20 is provided. The inner surface is defined as the inner surface and the outer surface is defined as the opposite side. In addition, about the right and left, when it looked toward the wall surface 1, the left and the right were made into the reference | standard.

  The connection reinforcement tool 10 shown in FIG. 1 is a connection tool that reinforces the connection between the side plates 21 and 22 and the back plate 23 in the storage unit 20 (see FIG. 3) whose bottom side is open. The storage unit 20 includes at least a pair of side plates 21 and 22, a back plate 23, and a crosspiece 25 disposed below the back plate 23 and connecting the opposing side plates 21 and 22. In this connection reinforcing tool 10, the first horizontal piece 11 a arranged so as to protrude from the plate surface of the side plate 21 and the second horizontal piece 11 b arranged so as to protrude from the plate surface of the crosspiece 25 are integrated. It has the horizontal plate piece 11 of the planar view L-shape. As shown in FIGS. 1 and 2, the first horizontal piece 11 a of the connection reinforcing tool 10 is bent and extended in the first horizontal piece 11 a that is fixed to the plate surface of the side plate 21, and the second horizontal piece 11 a. A second fixing piece 14 fixed to the plate surface of the crosspiece 25 is bent and extended on the piece 11b.

  First, a detailed configuration and shape of the storage unit 20 to which the connection reinforcing tool 10 is attached will be described.

  As shown in FIG. 3, the storage unit 20 to which the connection reinforcing tool 10 is attached is a box-type storage body that is attached and fixed to the wall surface 1. The storage unit 20 includes a top plate 24, two left and right side plates 21, 22, a back plate 23, a crosspiece 25, and a plurality of shelf plates 26. There is no bottom plate, and the bottom side is open. Has been. In the state shown in FIG. 3, the lower ends of the side plates 21 and 22, which are the lower ends of the storage body, are in a height position separated from the floor surface 2 in a state where the storage unit 20 is attached to the wall surface 1. For example, the storage unit 20 is installed with the lower end being separated between entrance soils. For example, a longitudinal object such as a golf bag is placed vertically with the lower part exposed using the space below the storage unit 20.

  The top plate 24 has a substantially rectangular flat plate shape elongated in the left-right direction, and is fixed so as to be bridged over the upper ends of the side plates 21 and 22. The plate width dimension (front-rear dimension) of the top plate 24 is substantially the same as the plate width dimension of the side plate 21 disposed on the left side. The side plates 21 and 22 are substantially rectangular flat plates that are long in the vertical direction, and the depth dimension of the left side plate 21 is larger than that of the right side plate 22. The reason why the left side plate 21 has a dimension that protrudes slightly forward is to provide a hinge portion of the door 29 as will be described later.

  A crosspiece 25 is fixed between both side plates 21 and 21 between lower end portions on the rear end side of the left and right side plates 21 and 22 whose upper ends are connected via a top plate 24. That is, both side plates 21 and 22 are connected via other members at the upper and lower ends.

  Further, a back plate 23 is disposed between the upper end surface 25a of the crosspiece 25 and the back surface of the top plate 24 so as to be sandwiched between them. The back plate 23 and the side plates 21 and 22 are connected by L-shaped metal fittings (not shown) at a plurality of positions in the vertical direction. Note that the back plate 23 may be configured by separating a plurality of back plates.

  A plurality of shelves 26 are arranged in an internal storage space 28 surrounded by the top plate 24, the side plates 21 and 22, and the back plate 23. The shelf plate 26 has a substantially rectangular flat plate shape, and the storage unit 20 shown in FIG. 3 has a movable type and a fixed type disposed between the side plates 21 and 22.

  Although not shown in FIG. 3, a door 29 such as a folding door (see FIG. 2B) or a hinged door is hingedly connected to the front side of the left side plate 21 on the front side of the storage unit 20. It is installed. The door 29 is not limited to a hinged door and may be a sliding door.

  Further, the other storage units 20 that are symmetrical to the above storage unit 20 (with the side plate 21 having a large depth on the right side) are connected to the side plates 22 and 22 as indicated by the two-dot chain line in FIG. They can also be arranged in contact with each other or in close proximity. Such a continuous storage unit 20A (see FIG. 4) will be described later together with the description of FIG.

  The storage unit 20 is configured as described above, and as described above, there is no bottom plate and the bottom side is open. In this storage unit 20, since there is no bottom plate connecting the side plates 21 and 22, the rigidity between the side plates 21 and 22 is connected and strengthened by the crosspiece 25 as described above. This crosspiece 25 supports the back plate 23 from below. And in this storage unit 20, the connection reinforcement tool 10 mentioned above is attached for the further reinforcement of rigidity.

  The connection reinforcing tool 10 is an L-shaped connection tool that is attached to a portion indicated by a broken line in FIG. 3 facing the storage space 28 side of the storage unit 20. That is, the connection reinforcing tool 10 is attached so as to be in contact with the plate surface of the left side plate 21, the plate surface of the crosspiece 25, and the entering corner 27 between them. In the example of this embodiment, the height position of the upper surface of the horizontal plate piece 11 to be described later of the connection reinforcing tool 10 is attached so as to substantially match the upper end surface 25a of the crosspiece 25. In addition, the other connection reinforcement tool 10 (refer FIG.2 (b)) is attached to the right side board 22 and the crosspiece 25. FIG.

  Next, a detailed configuration, shape, and mounting mode of the connection reinforcing tool 10 will be described with reference to FIGS. 1 (a) to 1 (d) and FIGS. 2 (a) and 2 (b). This connection reinforcement tool 10 is a metal connection tool attached to the left side of the storage unit 20. The other connecting reinforcing tool 10 attached to the right side is a member different from that shown in FIG. 1, but has a symmetrical shape in plan view as shown in FIG. The illustration is omitted for. Moreover, the dimension of each part of both the connection reinforcement tools 10 is the same. About each part of the right side connection reinforcement tool 10, the same code | symbol as the left side connection reinforcement tool 10 was attached | subjected in FIG.2 (b). In the case of the storage unit 20 shown in FIG. 3 of the present embodiment, since the door 29 is not attached to the right side plate 22, there is no possibility of swinging to the left or right as much as the left side plate 21. Therefore, the connection reinforcing tool 10 may not be attached to the right side plate 22.

  The horizontal plate piece 11 of the connection reinforcing tool 10 is formed in an L shape in a plan view in which a first horizontal piece 11a and a second horizontal piece 11b constituting the horizontal plate piece 11 are coupled via a bent portion 12. The first horizontal piece 11a is formed with a first fixed piece 13 that is bent and extended downward at one end in the width direction. The first horizontal piece 11b is provided with a lower end at one end in the width direction. A second fixed piece 14 that is bent and extended is formed.

  The dimension in the longitudinal direction of the first horizontal piece 11 a is slightly smaller than the depth dimension of the side plate 21. When the connection reinforcing tool 10 is attached to the storage unit 20, the planar space from the longitudinal end to the front end of the side plate 21 is the thickness dimension of the door 29 for attaching the door 29 to the side plate 21 by hinge connection. The space is generally matched. The right side plate 22 does not have a space for hinge connection, and its size is slightly small, which is substantially the same as the length in the longitudinal direction of the first horizontal piece 11a of the other connection reinforcing tool 10 (see FIG. 2B). I'm doing it. Of course, the first horizontal piece 11 a of the connection reinforcing tool 10 does not protrude beyond the front end of the side plate 22.

  Moreover, the dimension of the longitudinal direction of the 2nd horizontal piece 11b is smaller than 1/2 of the 1st horizontal piece 11a in a thing of an example, and larger than 1/3.

  The first horizontal piece 11a has a substantially uniform width dimension over its entire length in the longitudinal direction, and has an inner corner rounded at the open end (front) in the longitudinal direction for safety reasons. ing. Similarly, the second horizontal piece 11b has a substantially uniform width over the entire length in the longitudinal direction, and has a rounded inner corner at the open end (right side) in the longitudinal direction.

  In addition, the inner corner 12a of the bent portion 12 where the first horizontal piece 11a and the second horizontal piece 11b intersect each other has a shape that protrudes slightly inward (on the storage space 28 side). In the illustrated example, the inner line shape in plan view including the inner corner 12a of the horizontal plate piece 11 is a shape in which a corner is cut into a curved shape in a rectangle. Note that the shape is not limited to a curved shape, and may be an inclined linear shape. In addition, the intersection angle between the first horizontal piece 11a and the second horizontal piece 11b matches the proper angle of the corner 27 between the side plate 21 and the crosspiece 25 (back plate 23), and is approximately 90 degrees. .

  On the other hand, the first and second fixing pieces 13 and 14 have a substantially uniform width dimension over the entire length in the longitudinal direction, and are used for a fixture for fixing to the side plate 21 and the pier 25 along the longitudinal direction. A plurality of insertion holes 13a and 14a are opened.

  The first and second fixing pieces 13 and 14 are not directly connected to each other, and are adjacent to each other outside the bent portion 12 with a gap. Specifically, the connection reinforcing tool 10 is formed by bending a single plate-like body as shown in FIG. In addition, as shown in FIG.1 (c), the corner | angular part equivalent to the upper end of the protruding corner part 12b of the bending part 12 is cut off in the hole shape in order to avoid generation | occurrence | production of the crack at the time of bending formation.

  The angle formed between the first horizontal piece 11a and the first fixed piece 13 is approximately 90 degrees as shown in FIG. The second horizontal piece 11b and the second fixed piece 14 are also bent at approximately 90 degrees, although not shown. Therefore, if at least one of the first and second fixed pieces 13 and 14 is attached to the vertical surface so that the edge in the longitudinal direction thereof is substantially horizontal, the horizontal plate piece 11 is naturally in a substantially horizontal state. Become.

  In this embodiment, as shown in FIG. 2A, the connection reinforcing tool 10 has a bent corner 12 with a protruding corner 12 b (see FIGS. 1A and 1B) between the side plate 21 and the pier 25. It is attached with a fixing tool such as a screw so as to be applied to the entering corner 27. In the example of FIG. 2A, the height position of the surface of the horizontal plate 11 of the connection reinforcing tool 10 is approximately the same as the height position of the upper end surface 25 a of the crosspiece 25 fixed between the side plates 21 and 22. I'm doing it.

  As shown in FIG. 2 (b), if the connecting reinforcing tool 10 is correctly attached to the storage unit 20, the horizontal plate piece 11 is almost free from gaps between the side plate 21, the entrance corner 27, and the crosspiece 25. Will be arranged. Of course, the same applies to the right connection reinforcing tool 10.

  As described above, since the connecting reinforcing tool 10 has the horizontal plate piece 11 placed and fixed in the corner 27 without a gap, the connection between the side plate 21 and the back plate 23 is strengthened, and the side plate 21 and the back plate 23 are formed. It is possible to prevent the angle from fluctuating. Therefore, the rigidity of the storage unit 20 can be improved.

  Further, unlike the thin L-shaped metal fitting used as the conventional connecting structure of the storage body, the connection reinforcing tool 10 is formed of a thin plate material, but the first and second horizontal pieces 11a and 11b are It is formed with a spread in the horizontal direction so as to protrude in the horizontal direction. Therefore, the present connecting reinforcing tool 10 is strong against a load in the horizontal direction such as the horizontal direction, and is particularly suitable for preventing the side plate 21 that is subjected to a large load as the door 29 is opened and closed. In order to further improve the rigidity, it is desirable that the longitudinal dimension of the first horizontal piece 11a is substantially the same as or slightly smaller than the depth dimension of the side plate 21 as in the present embodiment. In addition, since the horizontal plate piece 11 covers a fixing tool such as a screw attached to the first and second fixing pieces 13 and 14, the connecting reinforcing tool 10 does not deteriorate the appearance.

  Further, the inner corner 12a of the bent portion 12 where the first horizontal piece 11a and the second horizontal piece 11b intersect with each other protrudes further inward. Therefore, the plate | board surface of the board protruded in the horizontal direction can be further extended in the site | part. As a result, the bent portion 12 of the connection reinforcing tool 10 becomes strong, the deformation and breakage of the connection reinforcing tool 10 itself can be prevented, and the state where the rigidity that the side plate 21 does not shake is reinforced can be maintained for a long time. it can.

  Furthermore, in this embodiment, since the connection reinforcement tool 10 is attached so that the upper surface of the horizontal plate 11 and the upper end surface 25a of the crosspiece 25 are substantially flush with each other, the left and right connection reinforcement tools 10 and the crosspiece 25 are attached. Other movable shelves can also be installed using

  In addition, as for the connection reinforcement tool 10, it is desirable to be integrally formed like this embodiment for intensity | strength maintenance. It is desirable that at least the first horizontal piece 11a and the second horizontal piece 11b are integrally formed. Further, the connection reinforcing tool 10 may be one in which the integrally formed horizontal plate piece 11 and the first and second fixing pieces 13 and 14 are integrated by welding or the like. Furthermore, the connection reinforcement tool 10 is not restricted to metal, and may be made of hard resin.

  Moreover, although the 1st, 2nd fixing pieces 13 and 14 are distribute | arranged below the horizontal plate piece 11, the connection reinforcement tool 10 of this embodiment is attached so that it may distribute | arrange upward. Good. With such a configuration, when the connecting reinforcing tool 10 is retrofitted after the storage unit 20 is attached to the wall surface 1, the attachment work is easy.

  Next, the continuous storage unit 20A will be described with reference to FIG.

  This continuous storage unit 20A includes a storage unit 20 that is symmetrical to the storage unit 20 shown in FIG. 3, and a side plate 22 having a small size is adjacent to the same height as shown by a two-dot chain line in FIG. It is a continuous storage body arranged to fit. In any storage unit 20, a folding door (door 29) is attached to a side plate 21 having a large size. In the continuous storage unit 20A, if the two doors 29 are closed, the two side plates 22 in the center are hidden, and the side plates 22 are not obstructed as an internal partition. The adjacent side plates 22 have a smaller plate width dimension.

  Such a continuous storage unit 20 </ b> A can be attached from the entrance soil to the roof. That is, one storage unit 20 (for example, the left one) can be installed so as to be placed on the floor surface of a raised bowl (not shown).

  In this continuous storage unit 20 </ b> A, the connection reinforcing tool 10 is attached to two locations of the large-size side plates 21 arranged on the left and right. The effect of the connection reinforcing tool 10 in the continuous storage unit 20A will not be described for those similar to those described above. In addition, since the center both side plates 22 can obtain sufficient strength by being adjacent to each other or being fixed to each other, it is not necessary to attach the connecting reinforcing tool 10 to the center. Another connecting reinforcing tool that matches the size of the side plate 22 may be attached.

  In addition, since the connection reinforcing tool 10 is not attached to the lower end of the storage unit 20, the lower end of the storage unit 20 can be kept flat, and the storage unit 20 can be stored even when the storage unit 20 is directly placed on the floor surface such as a raised basket. There is no risk of rattling.
