Description

[Technical Field]

[0001] The present invention relates to a sliding shelf device equipped with slide rails that allow shelves on which products are displayed to move in the forward and backward directions. [Background technology]

[0002] Shelving units for displaying products are used in supermarkets, convenience stores, etc. When stocking products, old products are moved to the front of the shelf body and new products are replenished at the rear of the shelf body, a so-called first-in, first-out system. To facilitate this first-in, first-out system, sliding shelving units equipped with shelves that are supported so as to be able to slide back and forth have been used (see, for example, Patent Document 1).

[0003] The sliding shelving device disclosed in Patent Document 1 includes a support post with a locking hole on the front surface, a pair of left and right brackets with hooks that can be locked into the locking holes of the support post, and a shelf board that is supported on the brackets via slide rails so that it can slide back and forth in the front and rear direction. The slide rails have a two-stage sliding structure in which a fixed rail member and a running rail member are arranged on the left and right, and the running rail member moves back and forth relative to the fixed rail member. The left and right slide rails are configured so that the fixed rail member is attached to the left and right brackets, and the running rail member is attached to the shelf board, and the shelf board is supported by the brackets via the pair of left and right slide rails.

[0004] [Patent Document 1] Jpn. Jpn. Pat. Appln. KOKAI Publication No. 63-13751 (page 2, Figure 2) Summary of the Invention [Problem to be solved by the invention]

[0005] The sliding shelving device of Patent Document 1 has a plurality of downward-opening engagement grooves on the front and rear sides of the shelf plate, and a plurality of upward-facing engagement pieces on the front and rear sides of the running rail member adjacent to the shelf plate. The engagement grooves engage with the engagement pieces from above, allowing the shelf plate to be easily attached to the sliding rail. Meanwhile, a plurality of screw holes are formed on the front and rear sides of the bracket, and a plurality of through holes are formed on the front and rear sides of the fixed rail member adjacent to the bracket. The sliding rail is attached to the bracket by inserting screws into the through holes from the inside of the fixed rail member and threading them into the drilled holes in the bracket. Because the screws used to attach the bracket to the sliding rail are inserted from the inside of the fixed rail member that constitutes the sliding rail and rotated to thread into the drilled holes, the running rail member must be pulled out of the fixed rail member to secure the screws, making the installation process cumbersome.

[0006] The present invention has been made in view of these problems, and has as its object to provide a sliding shelf device that can be easily assembled. [Means for solving the problem]

[0007] In order to solve the above problems, the sliding shelf device of the present invention is A sliding shelf device comprising: a base member having a locking hole on the front surface; a pair of left and right brackets having hooks that can be locked in the locking holes; and a shelf board supported on the brackets via slide rails so as to be slidable in the front-rear direction, The slide rail has a plurality of claws at the front and rear that protrude from a surface facing the paired bracket, The bracket has openings on its outer surface that can be engaged with the claws. And, The vehicle further includes a horizontal rod installed between the pair of left and right brackets, The bracket has a slit formed therein at approximately the same height as the slide rail, the slit penetrating the bracket in the left-right direction and extending in the front-rear direction, The horizontal rod has flange portions extending downward at both ends in the longitudinal direction and engaged with the slits, and also has a rising portion extending upward inward from the flange portions. It is characterized by the fact that According to this feature, the slide rail is prevented from tilting and is securely held in the bracket by engaging the front and rear claws of the slide rail with the front and rear openings formed on the outer surface of the bracket. In addition, because the slide rail and bracket are configured to engage with the claws on the slide rail and the openings on the bracket on the opposing surfaces, the slide rail can be easily attached to the bracket regardless of the extended state of the slide rail.

[0008] The slide rail is characterized in that it is provided with the claw portion formed facing downward and the claw portion formed facing rearward. According to this feature, the downward-facing claw portion engages with the opening in the up-down direction, while the backward-facing claw portion engages with the opening in the front-to-back direction.Since the engagement directions are different, the slide rail and bracket are less likely to become disengaged from each other due to sliding operations or unexpected contact with the shelf, making it safer.

[0009] The opening is characterized by being a through hole. This feature makes it safer as the claws are less likely to come off the opening.

[0010] A plurality of locking portions that are open up and down are provided on the front and rear of the surface of the slide rail facing the shelf board, The shelf board has a plurality of locking pieces at the front and rear of the shelf board, which protrude downward from the lower left and right ends and are locked from above by the locked portions, At least one of the front and rear locking pieces is characterized in that the lower end is formed facing either the front or rear direction. According to this feature, one of the locking pieces provided on the shelf board penetrates the locked portion of the slide rail from above, and its lower end extending in the front-to-back direction protrudes to either the front or rear of the locked portion.This locking allows the shelf board to be easily attached to the slide rail, while making it less likely for the shelf board to come off the slide rail due to sliding operations or unexpected contact with the shelf board.

[0011] The vehicle further includes a horizontal rod installed between the pair of left and right brackets, The bracket has a slit formed therein that penetrates in the left-right direction and extends in the front-rear direction, The horizontal rod is characterized by having flange portions at both left and right ends that extend downward and engage with the slits, and also having a rising portion that extends upward and inward from the flange portions. According to this feature, the flange portions at both ends of the cross rod are engaged with the slits on the left and right side of a pair of brackets, and the brackets are sandwiched between these flange portions and the rising portion from the left and right. This allows the cross rod to prevent the brackets from swinging left and right with a simple structure that does not use screws.

[0012] The shelf board further includes a locking member extending in the left-right direction and capable of being engaged with the front end of the bracket at the front end of the shelf board, The locking member has slits that penetrate in the front-to-back direction at both left and right ends and extend in the up-to-down direction, and the slits engage with claw portions formed at both left and right ends of the lower part of the shelf board, allowing the locking member to be attached so as to be freely swingable back and forth relative to the shelf board. According to this feature, the locking member can be attached so that it can swing freely by engaging the slits on both the left and right ends of the locking member with the claw portions formed on both the left and right ends of the lower part of the shelf, and with a simple structure that does not use shaft members, etc., relative movement between the shelf and the bracket in the stored state can be prevented.

[0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A sliding shelf device according to the present invention will be described below with reference to an embodiment. [Example]

[0015] A sliding shelf device according to an embodiment will be described with reference to Figures 1 to 15. In the following description, the lower left side of the paper in Figure 1 is the front side (front side) of the sliding shelf device.

[0016] Sliding shelf devices are used in supermarkets, convenience stores, etc., when displaying multiple products in the depth direction and left and right directions, and are used in a variety of situations, such as product display shelves that display products at room temperature and refrigerated showcases that are installed in stores where customers move around. Note that sliding shelf devices are not limited to product display shelves and refrigerated showcases, but may also be used as product storage shelves that store products in warehouses, etc. Furthermore, in this embodiment, an example will be described in which the sliding shelf device is used as a product display shelf.

[0017] As shown in FIG. 1, the sliding shelving device 1 is mainly composed of a pair of support posts 2, 2 spaced apart from each other on the left and right, which are the base members of the sliding shelving device 1, and multiple upper and lower shelf units 5, 5, ... supported on the front surfaces of the support posts 2, 2, with items being able to be displayed on the upper surfaces of plate members 51 that make up the shelf units 5. The support posts 2, 2 have legs 6, 6 and are able to stand on their own. The front surfaces of the support posts 2, 2 are provided with a number of engagement holes 7, 7, ... aligned in a vertical row. As will be described in detail later, a shelf board 50 that makes up the shelf unit 5 can slide back and forth relative to a bracket 52 that also makes up the shelf unit 5.

[0018] As shown in Figure 2, the shelf unit 5 is composed of a pair of left and right brackets 52, 52 attached to the front of the supports 2, 2, a cross rod 33 installed between the brackets 52, 52, a pair of left and right slide rails 9, 9, and a shelf board 50 supported so that it can slide back and forth via the slide rails 9, 9.

[0019] As shown in Figures 2 and 3, the shelf board 50 comprises a plate member 51 which is a metal plate material, a reinforcing member 53 (see Figure 4) extending in the left-right direction and fixed to the center of the front and rear of the underside of the plate member 51, a price rail 15 extending in the left-right direction and fixed to the front end of the plate member 51, and side components 54, 54 attached to both the left and right ends of the plate member 51, and is also provided with a locking mechanism 55 at the front end.

[0020] 2 and 3, the front edge of plate member 51 is bent downward across the entire width in the left-right direction to form hanging portion 51b, to which price rail 15 is fixed. A price plate or the like (not shown) can be attached to price rail 15.

[0021] 3 and 4, the side component 54 is made of a metal plate and is formed to have a side portion 54b that forms the side of the shelf board 50, a base portion 54a that fits along the upper surface 51a of the plate member 51, and a hanging portion 54c that is formed on the inside and hangs down parallel to the side portion 54b. The side portion 54b is formed to have a wide vertical width at the front end and a narrow vertical width at other parts.

[0022] The hanging portion 54c has locking pieces 54A and 54B at the front and rear, and also has a forward-facing claw portion 54d at the front end.

[0023] Specifically, locking pieces 54A and 54B are formed by cutting out the hanging body. Locking piece 54A on the front side of the hanging body is formed between cutouts 54e and 54f spaced apart from each other in the front and rear directions, and hangs downward with a certain width. Locking piece 54B on the rear side is formed between cutouts 54g and 54h spaced apart from each other in the front and rear directions, and includes a hanging portion 54j that hangs downward and a rearward extending portion 54k that extends diagonally downward and rearward from the lower end of hanging portion 54j. The lower end of locking piece 54B, i.e., rearward extending portion 54k, is formed so that its width gradually decreases toward the tip.

[0024] As shown in Figure 3, the locking mechanism 55 consists of a locking member 56 operably provided on the front end of the shelf board 50, claw portions 54d, 54d of side components 54, 54 that are open forward at both left and right ends of the front end of the underside of the plate member 51, and lock hooks 52a, 52a (see Figure 7) described later that are formed on brackets 52, 52 with which the engaging portions 56e, 56e of the locking member 56 respectively engage.

[0025] 2, 3, 5, and 7, the locking member 56 extends across the left-right width of the plate member 51 in front of the slide rails 9, and is composed of a vertical surface portion 56a, a flat surface portion 56b extending rearward from the lower end of the vertical surface portion 56a, an inclined surface portion 56c extending diagonally upward and rearward from the rear end of the flat surface portion 56b, and an extending portion 56d extending diagonally upward and forward from the tip of the inclined surface portion 56c. The range from the extending portion 56d to a portion of the inclined surface portion 56c is formed to be longer in left-right width than the remaining portion, and this protruding portion protruding to the left and right constitutes an engaging portion 56e that can engage with the lock hooks 52a formed on the bracket 52.

[0026] The locking member 56 also has slits 56f, 56f extending vertically at both left and right ends across the vertical surface portion 56a and the flat surface portion 56b. The slits 56f, 56f are engaged with the claw portions 54d, 54d of the side components 54, 54 arranged at both left and right ends of the underside of the plate member 51, respectively, so that the locking member 56 is attached to the plate member 51 so as to be able to swing back and forth relative to the plate member 51.

[0027] More specifically, as shown in FIG. 6, the hanging portion 51b at the front edge of the plate member 51 is not fixed to the side components 54, 54 attached to both the left and right ends of the plate member 51, and the free end side is elastically deformable forward, i.e., counterclockwise, around the boundary between the hanging portion 51b and the top surface portion 51a, which is the base of the plate member 51 (see particularly FIG. 6(b)).

[0028] As shown in FIG. 6(a), the procedure for attaching locking member 56 to plate member 51 is to push vertical surface portion 56a of locking member 56 between claw portions 54d of side components 54 arranged on both the left and right ends of the underside of plate member 51 and hanging portion 51b of plate member 51. Then, the free end of hanging portion 51b of plate member 51 elastically deforms forward (see FIG. 6(b)), and accordingly, the insertion of vertical surface portion 56a of locking member 56 progresses, and claw portions 54d engage with slits 56f of locking member 56, so that locking member 56 is suspended below plate member 51. When the engagement between slits 56f and claw portions 54d is completed, the shape of hanging portion 51b of plate member 51 is restored, and the engagement between slits 56f and claw portions 54d is maintained (see FIG. 6(c)).

[0029] Locking member 56 is suspended so as to be able to swing back and forth within the range in which slit 56f is guided by claw portion 54d, and vertical surface portion 56a is designed to return toward hanging portion 51b of plate member 51 due to its own weight, i.e., a counterclockwise returning moment acts around the upper end of slit 56f due to its own weight, and vertical surface portion 56a abuts against hanging portion 51b, thereby defining the returned position. As shown in Figure 7(c), when shelf board 50 is located in the rear storage position, engaging portion 56e of locking member 56 engages with lock hook 52a formed on bracket 52, restricting forward movement of shelf board 50.

[0030] When stocking shelves, store clerks move old products to the front of shelf board 50 and replenish new products at the rear of board member 51, a so-called first-in, first-out system. As shown in Figure 8, first, the clerk places his or her palm up and places his or her fingers except for the thumb around the back side of shelf board 50, and pushes upward with the fingertips against flat surface 56b or inclined surface 56c of locking member 56, i.e., moves locking member 56 clockwise, thereby disengaging engaging portion 56e of locking member 56 from lock hook 52a of bracket 52.

[0031] As shown in Figures 2 and 5, the locking member 56 has a longitudinal dimension that extends to both the left and right ends of the plate member 51, so that a store clerk can access the locking member 56 from either the left or right side of the front end of the shelf board 50 and perform an unlocking operation to release the engagement between the engagement portion 56e of the locking member 56 and the lock hook 52a of the bracket 52.

[0032] 9, bracket 52 is made of a metal plate-like member, and has downward-facing hooks 52c, 52c, ... at its rear end and upward-standing lock hook 52a at its front end. Furthermore, left and right brackets 52A, 52B are symmetrical in shape and have openings 52d, 52e formed therein.

[0033] Next, openings 52d and 52e will be described based on one bracket 52A. Opening 52d is formed on the front and upper side of bracket 52A, penetrating the bracket in the left-right thickness direction. Opening 52d has a generally rectangular shape with rounded corners, and is formed so that its vertical dimensions are shorter than its front-to-rear dimensions. Specifically, the vertical and front-to-rear dimensions of opening 52d are slightly longer than the vertical and front-to-rear dimensions of claw portion 91a of slide rail 9, which will be described later.

[0034] The opening 52e is formed on the rear and upper side of the bracket 52A, penetrating it in the left-right thickness direction. The opening 52e has a generally rectangular shape with rounded corners, and its vertical dimensions are approximately the same as its front-to-rear dimensions. Specifically, the vertical and front-to-rear dimensions of the opening 52e are slightly longer than those of the claw portion 91b of the slide rail 9, which will be described later. The upper ends of the openings 52d and 52e are located at approximately the same position.

[0035] 10, the pair of left and right slide rails 9, 9 has three rail members 91, 92, 93 lined up on the left and right, with adjacent rail members moving back and forth relative to each other, creating a three-stage sliding structure. For each of the left and right slide rails 9, 9, rail member 91 is attached to bracket 52, and rail member 93 is attached to plate member 51, and plate member 51 is supported by brackets 52, 52 via the pair of left and right slide rails 9, 9.

[0036] The left and right slide rails 9A, 9B are symmetrical, and as shown in Fig. 10(a), slide rail 9A has claws 91a, 91b formed on its outer surface, i.e., the outer surface of the right rail member 91, and locked portions 93a, 93b formed on its inner surface, i.e., the inner surface of the left rail member 93. As shown in Fig. 10(b), slide rail 9B has claws 91a, 91b formed on its outer surface, i.e., the outer surface of the right rail member 91, and locked portions 93a, 93b formed on its inner surface, i.e., the inner surface of the left rail member 93. The locked portions 93a, 93b formed on rail member 93 are opened up and down by cutting and raising the plate outward.

[0037] The front claw portion 91a is formed by bending a wide metal plate, and is configured with a base portion 9a that is horizontal and perpendicular to the inner surface, and a hanging portion 9b that extends downward at a right angle from the tip of the base portion 9a and is parallel to the inner surface.

[0038] In contrast, the rear claw portion 91b is formed by bending a wide metal plate, and is configured with a base portion 9c formed vertically perpendicular to the inner surface, and an extension portion 9d extending rearward at a right angle from the tip of the base portion 9c and parallel to the inner surface.

[0039] Furthermore, the lower end of opening 52d formed in bracket 52 is positioned higher than opening 52e, and the upper end of claw 91a is positioned lower than claw 91b by the difference in height. As a result, the slide rail 9 is oriented horizontally when base 9a of claw 91a abuts on lower edge 52f of opening 52d and base 9c of claw 91b abuts on lower edge 52g of opening 52e.

[0040] As shown in FIGS. 2 and 10, the locked portions 93a and 93b of the slide rail 9 are formed at the front and rear ends of the inner surface of the innermost rail member 93 on the plate member 51 side, that is, penetrating vertically.

[0041] 1 and 2, a cross rod 33 is installed between the brackets 52, 52 to restrict left-right movement of the brackets 52, 52. As shown in Figures 2 and 11, the cross rod 33 is made of a metal plate, and both ends of the short side of the base 33a are bent to form rising portions 33b, 33c at the front and rear, and these rising portions 33b, 33c form a roughly U-shape that opens upward.

[0042] Both longitudinal ends of the base 33a of the horizontal rod 33 are bent downward to form flanges 33d. Gaps G are formed between the flanges 33d and the rising portions 33b and 33c in the left-right direction. Preferably, the gaps G are equal to approximately the thickness of the brackets 52A and 52B. As shown in FIG. 9, a horizontally extending slit 52b is provided behind the rear opening 52e of the bracket 52, penetrating the bracket 52 in the left-right thickness direction, and the flange 33d of the horizontal rod 33 can be inserted into the slit 52b.

[0043] Next, the assembly procedure for the sliding shelf device 1 will be explained step by step using Figures 12 to 14. First, the slide rails 9 are attached to a pair of left and right brackets 52, respectively. Specifically, as shown in Figure 12(a), the rear claw portion 91b of the slide rail 9 (rail member 91) is inserted into the rear opening 52e of the bracket 52. In this state, as shown in Figure 12(b), the slide rail 9 and the bracket 52 are moved relatively forward and backward until the base 9c of the rear claw portion 91b approaches the rear edge 52h of the opening 52e. At this time, the extension portion 9d overlaps the outer surface of the bracket 52 behind the opening 52e, and the front claw portion 91a is moved to a position corresponding to the front opening 52d on the left and right.

[0044] 12(c), after inserting front claw portion 91a into front opening 52d, slide rail 9 and bracket 52 are moved vertically relative to each other, whereby base portion 9a of front claw portion 91a is placed on lower edge portion 52f of front opening 52d and hanging portion 9b is superimposed on the outer surface of bracket 52 below opening 52d. At the same time, the lower end portion of base portion 9c of rear claw portion 91b is placed on lower edge portion 52g of rear opening 52e.

[0045] As a result, the load of the slide rail 9 is supported by the bracket 52, and the bracket 52 is sandwiched between the opposing surface 9e of the slide rail 9 facing the bracket 52, the hanging portion 9b of the front claw portion 91a, and the extension portion 9d of the rear claw portion 91b, thereby restricting the left-right movement of the slide rail 9 and the bracket 52.

[0046] Furthermore, the downwardly formed front claw portion 91a engages with the front opening 52d in the up-down direction, whereas the rearwardly formed rearward claw portion 91b engages with the rear opening 52e in the front-to-back direction. As the engagement directions are different, the slide rail 9 and bracket 52 are less likely to become disengaged from each other due to sliding operation or unexpected contact with the plate member 51, which makes the slide rail 9 safer.

[0047] Next, as shown in Figure 13(a), a pair of left and right brackets 52, 52 are connected by a horizontal rod 33. With the horizontal rod 33 tilted relative to the brackets 52, 52, the flanges 33d, 33d at both longitudinal ends are inserted into the slits 52b, 52b of the brackets 52, 52. As a result, as shown in Figure 14, the left and right ends 33e, 33e of the base 33a of the horizontal rod 33 located inside the flange 33d, are placed on the lower edge of the slit 52b, the flange 33d of the horizontal rod 33 is superimposed on the outer surface of the bracket 52, and the rising portions 33b, 33c of the horizontal rod 33 are superimposed on the inner surface of the bracket 52, restricting relative movement between the bracket 52 and the horizontal rod 33 in the up-down and left-right directions.

[0048] 13(b), with the brackets 52, 52 attached to both longitudinal ends of the cross rod 33, the hooks 52c, 52c, ... at the rear ends of the left and right brackets 52, 52 are engaged with the engaging holes 7, 7 of the posts 2, 2, respectively, so that the left and right brackets 52, 52 connected by the cross rod 33 are supported on the posts 2, 2. By attaching the left and right brackets 52, 52 to the posts 2, 2 in this way, the relative inclination between the cross rod 33 and the brackets 52, 52 is restricted, and the flange portion 33d of the cross rod 33 does not slip out of the slit 52b of the bracket 52, increasing the assembly strength.

[0049] Finally, the shelf board 50 is attached to the slide rails 9, 9. First, as shown in Figure 15(a), the rear locking piece 54B of the side component 54 provided below the plate member 51 is inserted into the locked portion 93b on the rear side of the slide rail 9 (rail member 93). At this time, the shelf board 50 is tilted with the front side lifted so that the lower end of the locking piece 54B, i.e., the rear extension portion 54k, can be inserted into the locked portion 93b of the slide rail 9 from above.

[0050] 15(b), with rearward extending portion 54k of rearward locking piece 54B inserted into rearward locked portion 93b of slide rail 9, the front side of shelf board 50 is lowered using rearward locking piece 54B and locked portion 93b as a pivot point, and frontward locking piece 54A is engaged with frontward locked portion 93a of slide rail 9. By lowering the front side of shelf board 50 in this manner, rearward extending portion 54k of rearward locking piece 54B protrudes from below rearward locked portion 93b of slide rail 9 and moves below the rear edge of locked portion 93b, preventing the rear side of shelf board 50 from lifting upward relative to slide rail 9.

[0051] As described above, the slide rail 9 of the sliding shelf device 1 in this embodiment has a plurality of claws 91a, 91b on the front and rear sides that protrude from the surface 9e facing the mating bracket 52, and the bracket 52 has openings 52d, 52e on its outer surface with which the claws 91a, 91b can engage, respectively, so that the front and rear claws 91a, 91b provided on the slide rail 9 engage with the front and rear openings 52d, 52e formed in the bracket 52, thereby preventing tilting of the slide rail 9 and enabling it to be securely held by the bracket 52. Furthermore, because the slide rail 9 has a configuration in which the claws 91a, 91b on the slide rail 9 engage with the openings 52d, 52e on the bracket 52 on the surfaces facing the slide rail 9 and the bracket 52, the slide rail 9 can be easily assembled to the bracket 52 regardless of whether the slide rail 9 is pulled out.

[0052] Furthermore, the claws 91a, 91b protrude from the surface 9e of the slide rail 9 facing the bracket 52 and engage with the openings 52d, 52e of the bracket 52. In a conventional configuration in which screws are used to fasten the slide rail 9 to the bracket 52, there is a risk that the slide rail 9 and the screws will interfere with each other when the slide rail 9 is in operation if the screws become loose. However, when the mounting structure of this embodiment is employed, the fastening means between the slide rail 9 and the bracket 52 is always kept free from interference, ensuring smooth sliding operation.

[0053] Furthermore, since the openings 52d and 52e are through holes, the claws 91a and 91b of the slide rail 9 are unlikely to come off the openings 52d and 52e, providing excellent assembly strength and safety.

[0054] Furthermore, the flange portions 33d, 33d at both the left and right ends of the cross rod 33 are engaged with the slits 52b, 52b on the left and right side of the pair of brackets 52, 52, and the brackets 52, 52 are sandwiched between these flange portions 33d, 33d and the rising portions 33b, 33c from the left and right, respectively. This simple structure does not use screws, and prevents the brackets 52, 52 from swinging left and right by the cross rod 33.

[0055] Furthermore, as described above, the shelf board 50 and slide rail 9, the slide rail 9 and bracket 52, the brackets 52, 52 and cross rod 33, and the plate member 51 and locking mechanism 55 can all be assembled without using fixing means such as screws, making the assembly work simple and reducing the number of parts required, resulting in low costs.

[0056] Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention also includes modifications and additions that do not deviate from the gist of the present invention.

[0057] For example, in the above embodiment, the front claw 91a of the slide rail 9 faces downward, and the rear claw 91b faces backward. However, the present invention is not limited to this. For example, the front claw may face forward, and the rear claw may face downward. Also, three or more claws may be formed in the front and rear. In this case, it is sufficient that at least one claw faces downward, and openings of corresponding shapes are formed on the bracket 52 side.

[0058] In the above embodiment, the locking pieces 54A, 54B formed on the plate member 51 are formed so that the front locking piece 54A faces downward and the rear locking piece 54B has a tip that extends rearward, but this is not limiting, and for example, the front locking piece may be formed with a tip that extends forward and the rear locking piece is formed with a downward facing tip. Also, three or more locking pieces may be formed on the front and rear sides, in which case it is sufficient that at least one locking piece faces downward, and that a locked portion of a corresponding shape is formed on the slide rail side.

[0059] Furthermore, in the above embodiment, the openings 52d and 52e on the bracket 52 side that engage with the claw portions 91a and 91b formed on the slide rail 9 are through holes, but this is not limited to this, and for example, the openings may be notches that are open upward.
