[0016]
Each of these components will be described. The shelf column 25 is made of a stainless steel plate, and a plurality of engagement holes 24 are opened at a predetermined interval in the vertical direction. The shape of the engagement hole 24 is a quadrangle. There are a total of four standing on the left and right side surfaces in the storage chamber 8 and fixed to the inner side surface of the heat insulating box 5 with a plurality of screws 51. The drawing shows only two front and rear shelf columns 25 standing on the right inner surface when viewed from the front of the storage chamber 8, but the same applies to the left inner surface.
[0017]
The shelf holder 50 is made of a stainless steel plate and has a substantially “F” cross section. An upper protrusion 50a is formed on the upper end surface, an intermediate protrusion 50b is formed on the bent portion, and a lower protrusion 50c is formed on the lower end surface. The width of the upper protrusion 50 a and the lower protrusion 50 c is slightly smaller than the width of the rectangular engagement hole 24, and the height of the protrusion is slightly smaller than the height of the engagement hole 24. The height and width of the intermediate protrusion 50 b are arbitrary, but are smaller than the width of the shelf receiver 50 because the shelf receiver 50 is cut and raised.
[0018]
The bracket 28 is made of a steel plate and is an elongated columnar part having a substantially U-shaped cross section, and has a bending extending upward at the lower end portion. Two holes 28a into which the middle protrusions 50b of the shelf receiver 50 are inserted are opened on the upper surface. Further, two screw holes 28b for stopping the fixture 40 and two screw holes 28C for stopping the fixed side rail 29A of the slide rail 29 are formed. A bracket 38 is screwed to the tip of the bracket 28 with two screws 39. The receiving bracket 38 is formed from a single sheet metal, and the front side is an inclined surface 41 that is inclined lower forward, and the rear side is a hook 42 that descends substantially vertically.
[0019]
The fixture 40 has a substantially rectangular flat plate shape made of a steel plate, and two engaging claws 43 are formed near both end faces in the longitudinal direction of the flat plate. The engaging claw 43 extends upward from the side end surface of the fixture 40, leaves the sky on the side end surface almost horizontally in the middle, and extends upward again, and has a so-called fingernail shape. The width of the engaging claw 43 is slightly smaller than the lateral width of the engaging hole 24. The pitch between the two engaging claws 43-43 is equal to the pitch between the shelf columns 25-25, and therefore equal to the pitch between the engaging holes 24-24. Two holes 40a and two holes 40b are opened on the flat plate of the fixture 40, and each hole is positioned so as to match the holes 28a and 28b of the bracket 28, respectively.
[0020]
The slide rail 29 includes a fixed side rail 29A, a movable side rail 29B, a ball bearing 29C, and a bearing holder 29D. The bearing holder 29D has four rows of recesses at the top, bottom, left, and right ends, and a large number of bearings 29C are accommodated in the recesses. The fixed side rail 29A and the movable side rail 29B are wrapped around the bearings 29C from the outside. It's covered. In this state, the ball bearing 29C can no longer be removed from the recess, and the fixed side rail 29A and the movable side rail 29B can be slid relative to each other. These 29A, 29B, 29C, and 29D are assembled in advance and configured as an integral slide rail 29.
[0021]
The connecting plate 30 connects and integrates the brackets 28 separated from each other on the left and right, and is formed by bending a steel plate. The flange 31 connected to the bracket 28 is formed at both ends, and extends horizontally beyond the thickness width of the slide rail 29 from the flange 31 to form the horizontal portion 33. From there, it rises diagonally upward, forms a slope 32, and extends horizontally again before it hits the bottom of the shelf 3, thereby forming a connecting plate 30. The tip is formed in the same symmetrical shape as the right side. A flange 34 is provided to increase the strength of the connecting plate 30. A hole 31c is opened in the flange 31 to connect the left and right brackets 28.
[0022]
The shelf 3 is formed from a steel plate, and flanges 3a are formed on the four sides of the bottomed top opening for displaying products. An inverted hat type frame 37 is spot-welded to the lower surface of the shelf 3 at the points marked with * in FIG. The frame 37 has two holes 37 a for attaching the stopper 44. On the lower surface of the shelf 3, two mounting plates 34 for attaching the shelf 3 to the movable rail 29B are spot-welded at the points marked with * in FIG. The shape of the mounting plate 34 is L-shaped, and is made by bending a sheet metal.
[0023]
The stopper 44 is formed of a thin steel plate having elasticity. An attachment portion 46 is formed at the upper left portion when viewed from the upper right in FIG. 3, and this attachment portion 46 is fixed to the hole 37 a of the frame 37 of the shelf 3 with a screw 47. The shape of the stopper 44 is inclined horizontally forward after the mounting portion 46 and then becomes horizontal, and further extends in the right direction to form an elastic engagement portion 48. The elastic engagement portion 48 can be deformed in the direction in which the front end 48A moves up and down by using the elasticity. The rear side of the front tip 48A is a rear tip 48B that is cut with an inclined surface that is slightly inclined upward. The front edge portion of the elastic engagement portion 48 is a strip-shaped sheet metal that descends substantially vertically, and the lower end thereof is integrally formed by bending an operation portion 49 that is bent rearward at a substantially right angle. The operation unit 49 is baked and coated with resin so that it is safe even if it is touched by a human finger.
[0024]
With this configuration, the parts are assembled in the following order. First, the shelf 3 is fixed to the movable rail 29 </ b> B of the slide rail 29 with screws 52 via two mounting plates 34 spot welded to the left and right of the lower surface of the shelf 3. Then, at this time, the shelf 3 is integrated with the left and right slide rails 29.
[0025]
Next, the connecting plate 30 is brought from the lower side to the fixed side rail 29A of the slide rail 29, the flange 31 is applied, and the bracket 28 is also applied. Then, the screw 53 is inserted into the hole of the fixed rail 29A, the hole 31c of the flange 31, and the hole 28c of the bracket 28, and these three members are fastened together. Similarly, the left side bracket 31 and the left side flange 31 of the connecting plate 30 are fastened together with the left side rail 31A of the left slide rail 29, although not shown in the drawing. In this way, the fixed side rail 29A of the left and right slide rails 29, the connecting plate 30, and the left and right brackets are integrated.
[0026]
As described above, the movable rail 29B of the slide rail 29 and the shelf 3 are also integrated. In the slide rail 29, the fixed side rail 29A and the movable side rail 29B slide back and forth reciprocally. Accordingly, if the left and right brackets 28 connected to the fixed side rail 29A are held in hand, the shelf 3 slides back and forth freely at this point, and the shelf 3, the slide rail 29, the connecting plate 30, and the bracket 28 are It is in a state of integrated parts.
[0027]
Next, the shelf position in the storage room 8 is determined. This is done by inserting the shelf receiver 50 into the engagement hole 24 of the shelf column 25 individually. Since there are four shelves 25, it is important that the positions of the shelves 50 are the same height. After the upper protrusion 50a of the shelf receiver 50 is inserted into the engagement hole 24, the shelf receiver 50 is lifted upward, the lower protrusion 50c is inserted into another engagement hole 24, and the shelf receiver 50 is slid down. By doing so, the shelf receiver 50 is engaged with the shelf column 25. Four shelf holders 50 are set at a desired height.
[0028]
In another shelf assembly, the intermediate projection 50b of the shelf receiver 50 is inserted into the hole 28a of the bracket 28 so as to cover the bracket 28 from above the shelf receiver 50. When the four middle protrusions 50b enter the four holes 28a, the shelf assembly is fixed to the shelf receiver 50. And it doesn't move back and forth and left and right. However, upward disengagement is possible.
[0029]
Here, the fixture 40 is used. The engaging claw 43 of the fixture 40 is inserted into the engaging hole 24 of the shelf column 25. The engaging claw 43 contacts the upper end portion of the engaging hole 24. Then, the fixture 40 is rotated downward with the engaging claw 43 as a fulcrum, and is placed on the bracket 28, and the both are fixed by passing through the holes 40 b and 28 b with the screws 54. By doing so, the bracket 28 is prevented from moving upward by the engaging claws 43, and thus the shelf device 1 is fixed in the vertical direction in addition to the front, rear, left and right.
[0030]
By adding the fixture 40 in this manner, even in a conventional showcase installed in the market, the shelf holder 50 that is currently used can be used as it is, and it can be easily remodeled into a front / retractable movable shelf. Can do. Further, when remodeling, if the shelf 3, slide rail 29, connecting plate 30, bracket 28, etc. are assembled in advance and brought into the field, the work can be completed in a short time just by fixing the fixture 40 with the screws 54. . Since the space above the screw 54 is vacant, the screw tightening operation is also easy.
[0031]
The operation of the shelf device 1 configured as described above will be specifically described. In a state in which the shelf 3 is pushed into the storage chamber 8 and stored, the front end 48A of the elastic engagement portion 48 of the stopper 44 falls to the rear side of the hook 42 of the metal fitting 38 and is stuck. At this time, the entire elastic engagement portion 48 is in a substantially horizontal state, whereby the shelf 3 is stably held, and when the customer takes out the product, the shelf 3 may not move carelessly. Absent.
[0032]
Next, when the shelf 3 is pulled out from the inside of the storage chamber 8, if the finger is placed on the lower surface of the operation portion 49 of the stopper 44 and the operation portion 49 is lifted upward, the elastic engagement portion 48 is caused by its elasticity. The front tip 48A is deformed so as to move upward. Then, the front end 48A of the elastic engagement portion 48 gets over the hook 42, and the engagement between the two is released. Thus, the shelf 3 becomes free and can be moved forward. The store clerk can easily arrange beverage cans, plastic bottles, canned foods and the like on the shelf 3 pulled out to the front, and the display work becomes efficient.
[0033]
When goods are fully loaded with the shelf 3 pulled out forward, the weight is concentrated on the front part of the bracket 28. Then, a load is applied so that the shelf 3 is turned over to the front, and the rear shelf support 50 is lifted up with the two shelf supports 50 at the front. However, since the upper surface of the bracket 28 is pressed by the fixture 40 and the engagement claw 43 of the fixture 40 is in contact with the upper end of the engagement hole 24 of the shelf column 25, the bracket 28 can move upward. Accordingly, the shelf holder 50 cannot be moved upward and is held as it is, and is not detached from the engagement hole 24. Thus, even if the shelf 3 is pulled forward, the shelf receiver 50 does not come off the shelf support column 25.
[0034]
When the product display operation is completed and the shelf 3 is pushed back to return to the storage chamber 8, the rear end 48 </ b> B of the stopper 44 is lifted along the inclined surface 41 of the receiving bracket 38, and the elastic restoring force is obtained after overcoming the hook 42. Thus, the front tip 48A descends and engages the rear side of the hook 42. Thereafter, the shelf 3 is stably held and does not pop out forward carelessly.
[0035]
Next, another embodiment of the present invention will be described with reference to FIG. Components having the same configurations as those of the above-described embodiment shown in FIG. What is different from the configuration of FIG. The fixture 60 is fixed to the lower surface of the bracket 28 with screws 54, and an engagement piece 61 bent substantially vertically downward is attached to the right end surface. The engagement piece 61 is made slightly smaller in width than the lateral width of the engagement hole 24 of the shelf column 25, and the tip of the engagement piece 61 abuts on the upper end portion of the engagement hole 24 and then bends upward again. U-shaped. Two engaging pieces 61 are formed on the fixture 60 and screwed to the lower surfaces of the left and right brackets 28.
[0036]
Consider a case in which the shelf 3 is pulled forward and the products are fully displayed with such a configuration. Since the weight of the product concentrates on the front part of the bracket 28, the rear shelf receiver 50 tends to lift upward with the front shelf receiver 50 as a fulcrum. Then, since the “U” portion of the engagement piece 61 is constrained by the upper end portion of the engagement hole 24, the fixture 60 cannot move upward, and the screwed bracket 28 does not move upward, Accordingly, the shelf receiver 50 on which the bracket 28 is placed does not move upward and does not come off the shelf column 25. In this embodiment, since the engagement piece 61 reliably engages the engagement hole 24 like a fishhook, the stability of the shelf receiver 50 is extremely high.
[0037]
In the above embodiment, the metal fitting 38 having the hook 42 is a separate part. However, the screw 39 can be eliminated by integrally forming the bracket 28 with a sheet metal. Further, the shelf receiver 50 is made of stainless steel having a “F” shape, but may be resin-molded, and any material and shape may be used as long as it is inserted into the engagement hole 24 from above and engaged. .
[0038]
Although the embodiment of the invention has been described above, the invention is not limited to this embodiment, and can be changed within an equivalent range as described in the writing.
[0039]
【The invention's effect】
As described above, according to the first aspect of the present invention, the shelf height can be easily changed by replacing the shelf holder with the shelf support. And a shelf can be combined with a slide rail, and it can be set as a movable shelf only by couple | bonding this slide rail with a bracket. Further, the entire movable shelf is placed on the shelf holder and is held by a fixture from below the shelf holder, and the engagement piece of the fixture is restrained by the upper end portion of the engagement hole of the shelf column. Therefore, even a conventional showcase installed in the market can be easily remodeled into a front-and-back drawer type movable shelf while using the shelf holder currently used as it is. In addition, when remodeling, if shelves, slide rails, connecting plates, brackets, etc. are assembled in advance and brought into the field, the work can be completed in a short time just by fixing the fixing tool with screws. Furthermore, since there is a space in the downward direction of the screw, there is an effect that the screw tightening operation becomes easy. Since the “U” -shaped engagement piece securely engages the engagement hole like a fishing hook, the shelf holder has an extremely high stability.
[0040]
According to the second aspect of the present invention, since the fixtures are provided side by side on the left and right sides without being divided into four parts, there is an effect that the assembling work is simplified.
