[0009] A first invention provides a display room having a shelf board on which products are placed, the shelf board being movable and retractable to the outside of the display room, the shelf board having a locking member for locking the shelf board to a shelf board support member fixed to the display room, and an operating member for unlocking the locking member and the shelf board support member at the front of the shelf board, and spring members having the locking members fixed to rear end portions attached to both sides of the shelf board so as to be rotatable in the vertical direction, the spring members being comprised of at least a main body plate and a spring support extending laterally from the front end of the main body plate. Each shelf has a support portion and a leaf spring portion extending in an upwardly inclined manner from the tip of the spring support portion and biasing the locking member into a locked state, and the operating member is provided across the entire width of the front part of the shelf between the spring members and is configured to connect and fix the spring support members of each of the spring members on both sides, the tip of the leaf spring portion abuts the underside of the shelf, and the spring member is biased downward at the front by the biasing force of the leaf spring portion, and the lock is released by operating the operating member in an upward direction. According to this, the user can rotate the spring member and release the engagement between the engagement surface of the locking member and the engagement block by operating any position of the operating member in the width direction, thereby allowing the user to pull out the shelf. As a result, the user can pull out the shelf by operating the operating member with only one hand, improving usability. The operating member is provided across the entire width of the front part of the shelf.

[0010] In a second invention, the shelf support member has a locking block, the locking member has a locking surface that locks into the locking block, and when the spring member is rotated upward, the lock between the locking surface of the locking member and the locking block is released. With this, the locking member can be held in a locked state by the leaf spring portion, and the locking by the locking member can be released by rotating the spring member against the biasing force of the leaf spring portion.

[0011] In the third aspect of the present invention, when the operating member is operated to rotate the spring member upward, the engagement between the engaging surface of the locking member and the engaging block is released. According to this, the spring member can be rotated against the biasing force of the leaf spring portion to release the engagement between the engagement surface of the lock member and the engagement block.

[0012] In a fourth aspect of the invention, the locking member has a positioning portion that positions the locking member relative to the locking block when the locking surface is engaged with the locking block, and receiving portions that receive the locking block are provided on both sides of the positioning portion. According to this, since receiving portions for receiving the locking blocks are provided on both sides of the positioning portion of the locking member, it is possible to use the locking member as either the left or right spring member regardless of whether it is provided on the left or right side of the shelf. As a result, the locking member can be used as a common part for both the left and right spring members.

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing an embodiment of a showcase according to the present invention. 1, the showcase 10 is formed in a box shape, and an opening 11 is formed in the front. The parts other than the front are covered with a top plate 12, side plates 13, and a back plate (not shown) via insulating members (not shown), and the inside of the showcase 10 is insulated.

[0014] Two doors 15 are provided at the opening 11 of the showcase 10 so as to be able to be opened and closed freely. The doors 15 are provided with a rectangular door frame 16, and a transparent plate 17, for example, made of glass, is fitted inside the door frame 16. A handle 18 for opening and closing the doors 15 is attached to one side of the door frame 16. A display unit 19 is provided on the upper front surface of the showcase 10, and is made of, for example, a liquid crystal display element, for displaying the temperature inside the showcase 10, etc. The interior of the showcase 10 is a display room 20 for displaying products, and a plurality of shelves 21 are provided inside the display room 20. In this embodiment, seven shelves 21 are provided.

[0015] A refrigerator (not shown) installed outside the showcase is connected via a refrigerant pipe. The refrigerator includes a compressor, a heat exchanger (gas cooler) that cools the high-pressure refrigerant discharged from the compressor, and an expansion valve that expands the refrigerant sent from the heat exchanger (none of which are shown). The refrigerant compressed by the refrigerator compressor is cooled through a heat exchanger, expanded in an expansion valve, and then heat exchanged in an evaporator. The air that has been heat exchanged in the evaporator is sent to the inside of the display room 20, thereby cooling the inside of the display room 20 to a predetermined refrigeration temperature or freezing temperature.

[0016] Although details will be described later, each shelf board 21 is supported by a pair of shelf board support members 22 (see FIG. 2). A large number of engagement holes (not shown) are formed in the vertical direction on the rear side of the display chamber 20 of the showcase 10. The shelf board support member 22 is fixed to the inside of the display chamber 20 by engaging a hook 23 formed on the rear end of the shelf board support member 22 with the engagement hole.

[0017] Next, the shelf board 21 will be described. FIG. 2 is an exploded perspective view showing shelf board 21 of the present embodiment. FIG. 3 is a perspective view of shelf board 21 of the present embodiment as viewed from below. FIG. 4 is an exploded perspective view showing the attachment portion of the shelf board and the spring member of the present embodiment. FIG. 5 is an exploded perspective view showing the attachment portion of the shelf board and the spring member of the present embodiment. FIG. 6 is a vertical cross-sectional view showing the arrangement of the shelf board and the spring member of the present embodiment. FIG. 7 is a plan view of the shelf board and the spring member of the present embodiment. FIG. 8 is a side view showing the arrangement of the spring member of the present embodiment. FIG. 9 is a perspective view of spring member 40 of the present embodiment.

[0018] 2 to 7, raised portions 30 that extend slightly upward are formed on both side edges and the rear edge of shelf board 21 that is attached to shelf board support member 22. Raised portions 30 are formed to prevent products placed on shelf board 21 from falling, and raised portions 30 are not formed on the front edge of shelf board 21 to make it easier to put products on and take them out of shelf board 21. A front panel portion 31 is formed on the front edge of shelf board 21 as a reinforcing portion for preventing shelf board 21 from being distorted in the horizontal direction. The front panel portion 31 consists of a front surface portion 31a extending downwardly so as to be approximately perpendicular to the upper surface of the shelf board 21, a lower surface portion 31b extending rearward from the lower edge of the front surface portion 31a, and a stopper portion 31c extending upwardly from the rear edge of the lower surface portion 31b. The vertical length of the stopper portion 31c is determined in consideration of the relationship between the stopper portion 31c and the operating member 70, which will be described later.

[0019] Support plates 32 are attached to both sides of the shelf board 21. The support plate 32 is formed by bending a long plate, and has a horizontal surface and a vertical surface. One surface of the support plate 32 (the horizontal surface mentioned above) is fixed to the underside of both sides of the shelf board 21, and the other surface (the vertical surface mentioned above) extending in the vertical direction of the support plate 32 is approximately flush with both side edges of the shelf board 21.

[0020] A slide rail 35 is provided on the outer side of the shelf board support member 22. The slide rail 35 is composed of a fixed side rail 36 and a movable side rail 37. The fixed rail 36 is fixed to the outer surface of the shelf board support member 22 with screws or the like. The movable rail 37 is fixed to the inner surface of the support plate 32 of the shelf board 21 with screws or the like. As a result, the shelf 21 is attached to the shelf support member 22 via the slide rail 35, and the shelf 21 is freely movable back and forth relative to the shelf support member 22 as the movable side rail 37 of the slide rail 35 moves relative to the fixed side rail 36.

[0021] A spring member 40 made of, for example, a metal material is attached to the front portion of the inner surface of the support plate 32 so as to be rotatable relative to the support plate 32 . The spring member 40 comprises a planar main body plate 41, a wall plate 42 rising upward from one side edge of the main body plate 41, a rising plate 43 rising slightly upward from the other side edge of the main body plate 41, a spring support portion 44 extending laterally from the front end of the main body plate 41, and a leaf spring portion 45 extending at an angle upward from the tip of the spring support portion 44. The wall plate 42 of the spring member 40 functions as a mounting surface for mounting the spring member 40 to the support plate 32, and a screw hole 46 is formed in the wall plate 42 of the spring member 40. The spring member 40 is mounted to the support plate 32 via a screw 47 passing through the screw hole 46. In this way, the spring member 40 is mounted to the support plate 32 so as to be rotatable about the screw 47.

[0022] Further, the tip of the leaf spring portion 45 of the spring member 40 is in contact with the underside of the shelf board 21, and the spring member 40 is biased downward in front of the screw 47 by the biasing force of the leaf spring portion 45. In other words, the spring member 40 is configured so that when an upward force is applied to the front end portion of the spring member 40, the front of the spring member 40 can rotate upward against the biasing force of the leaf spring portion 45. In addition, the upward rotation is a movement in which any point on the rotating object, except for the center of rotation, draws a circle or an arc. Therefore, the above-mentioned rotation of the spring member 40 is, in more detail, a movement in which the front end portion of the spring member 40 moves upward and at the same time moves backward while drawing an arc. The same applies to the following explanation, but may be omitted for convenience.

[0023] A locking member 50 made of, for example, a resin material is provided at the rear end portion of the main body plate 41 of the spring member 40. The locking member 50 is held between the wall plate 42 and the rising plate 43, and is fixed to the main body plate 41 by screws or the like. The locking member 50 includes a positioning portion 51 and an engagement portion 52. The positioning portion 51 is formed so that the central portion in the width direction protrudes upward, and both side surfaces of this positioning portion 51 serve as positioning surfaces 53. The spaces between the positioning surfaces 53 and both side portions of the locking member 50 serve as receiving portions 54 for engagement blocks 60, which will be described later.

[0024] The locking portion 52 includes a locking surface 55 facing forward, an upper end surface 55a that is a surface continuing from the upper end of the locking surface 55, and an inclined surface 56 that is inclined so that the height decreases from the upper end surface 55a toward the rear end of the locking member 50. In addition, as shown in Fig. 8, a chamfer may be applied between the locking surface 55 and the upper end surface 55a. A locking block 60 is attached to the outer surface of the front end portion of the shelf board support member 22, with which the locking surface 55 of the locking portion 52 locks. The protruding dimension of the locking block 60 is formed to be approximately equal to the distance from one side edge of the locking member 50 to the positioning surface 53 , and the locking block 60 is positioned in the receiving portion 54 . In this case, the positioning portion 51 of the locking member 50 is provided in the center in the width direction, and the receiving portions 54 are provided on both sides of the positioning portion 51, so that the locking member 50 is formed symmetrically. This makes it possible for the locking member 50 to be applied to either the left or right spring member 40. When the locking surface 55 of the locking portion 52 is locked with the locking block 60, the shelf board 21 is locked and cannot be pulled out.

[0025] Then, as the front of the spring member 40 is rotated upward around the screw 47 against the biasing force of the leaf spring portion 45, the locking surface 55 of the locking portion 52 is moved downward, thereby releasing the lock of the locking surface 55 with the locking block 60. In this state, the shelf board 21 is unlocked, and the shelf board 21 can be pulled out forward via the slide rails 35. When returning the shelf board 21 to its original position, the shelf board 21 is pushed in, causing the inclined surface 56 of the locking portion 52 to abut against the locking block 60, and by further pushing the shelf board 21, the inclined surface 56 of the locking portion 52 moves along the locking block 60, causing the front portion of the spring member 40 to rotate upward against the biasing force of the leaf spring portion 45.

[0026] At this time, since the locking member 50 has a positioning portion 51 , when the inclined surface 56 of the locking portion 52 moves along the locking block 60 , the locking block 60 is guided into the receiving portion 54 by the positioning surface 53 of the locking member 50 . From this state, by pushing the shelf board 21 further in, the inclined surface 56 of the locking portion 52 climbs over the locking block 60 and is positioned in the receiving portion 54, whereby the locking surface 55 is locked by the locking block 60. This state in which the locking surface 55 is locked by the locking block 60 is referred to as the locked state of the shelf board 21. Although the configuration of the shelf support member 22, slide rail 35, support plate 32, spring member 40 and lock member 50 has been described for one side of the shelf 21, these configurations are provided symmetrically on both sides of the shelf 21.

[0027] An operating member 70 extending approximately parallel to the front edge of the shelf board 21 is provided between the spring support parts 44 of the spring members 40 located on both sides of the shelf board 21. A screw hole 48 is formed in the spring support part 44 of the spring member 40, and the spring members 40 on both sides and the operating member 70 are connected and fixed by a screw 49 inserted into the screw hole 48. The operating member 70 is provided across the entire width of the shelf board 21. The operating member 70 includes a fixed portion 70a fixed to the spring support portion 44 of the spring member 40, a rising portion 70b extending upward from the front end edge of the fixed portion 70a, a stopper receiving surface 70c extending forward from the front end edge of the rising portion 70b, and a second rising portion 70d extending upward from the front end edge of the stopper receiving surface 70c, and the operating member 70 has a stepped cross-sectional shape in the front-rear direction of the shelf board 21.

[0028] A cover member 71 located on the front side of the operating member 70 is attached integrally to the lower surface 31b of the front plate portion 31 of the shelf board 21 by screws or the like. As shown in Figure 8, the covering member 71 has a front surface portion 71a facing the front surface portion 31a of the front panel portion 31, a lower surface portion 71b extending rearward from the lower edge of the front surface portion 71a, and a rear surface portion 71c extending upward from the rear edge of the lower surface portion 71b and overlapping with the rear surface of the stopper portion 31c of the front panel portion 31, and the covering member 71 is formed into an approximately U-shaped cross-section in the fore-and-aft direction of the shelf board 21. The underside 71b of the covering member 71 is fixed to the underside 31b of the front plate 31, and in this state, a predetermined gap is formed between the front side 71a of the covering member 71 and the front side 31a of the front plate 31. This gap functions as a price rail for inserting a tag or plate on which the name or price of a product is displayed or printed, for example.

[0029] The operating member 70 operates each of the spring members 40 simultaneously, and by operating any part of the operating member 70 in a forward and upward direction, it is possible to rotate the front parts of each of the spring members 40 upward at the same time. When the operating member 70 is not operated by the user, the stopper receiving surface 70c is held in a state in which it abuts against the upper end of the stopper portion 31c of the front plate portion 31. The rear surface portion 71c of the covering member 71 is set to have a height dimension that is shorter (lower) than the height dimension of the stopper portion 31c of the front plate portion 31. Here, the set height dimension is the design dimension of each part, each member, or each portion.

[0030] As described above, the operating member 70 is held by the stopper receiving surface 70c abutting against the upper end of the front plate portion 31c, and is operated as described below to realize the functions of locking and unlocking the shelf board 21. In other words, the operating member 70 is held and the functions of locking and unlocking the shelf board 21 are realized by setting the dimensions of the other related members based on the height dimension of the front plate portion 31c. If the height dimension of the rear surface 71c of the covering member 71 and the height dimension of the stopper portion 31c of the front plate portion 31 are set to the same length, manufacturing errors of the respective components or assembly errors during assembly may cause the rear surface 71c of the covering member 71 to protrude above the stopper portion 31c of the front plate portion 31, resulting in deviation from the above-mentioned standard. In order to avoid such a situation, in this embodiment, the design dimensions of the rear portion 71c of the covering member 71 are set to a height dimension that is shorter than the height dimension of the stopper portion 31c of the front plate portion 31 so that each error falls within the allowable range.

[0031] Then, by operating the operating member 70, for example, near the center, toward the front and upper side, the user can simultaneously rotate the two spring members 40 around the screw 47. This releases the engagement between the engagement surface of the locking member 50 and the engagement block 60, allowing the shelf board 21 to be pulled out. In this case, the spring members 40 and the operating member 70 are provided to interlock with each other, and the operating member 70 is provided parallel to the width of the shelf 21, approximately equal to the length of the width of the shelf 21, so that the user can rotate the spring members 40 and release the engagement between the engagement surface of the locking member 50 and the engagement block 60 by operating the operating member 70 in any position. This allows the user to easily pull out the shelf board 21 with one hand.

[0032] Next, the operation of this embodiment will be described. When the locking surface 55 of the locking portion 52 is locked with the locking block 60, the shelf board 21 is locked and cannot be pulled out. In this state, predetermined products are displayed on the upper surface of the shelf board 21. Next, the operation of pulling out the shelf board 21 from the display chamber 20 will be described. 10(a), (b), and (c) are explanatory diagrams showing the operation of pulling out the shelf board 21. Figures 11(a), (b), and (c) are explanatory diagrams showing the operation of returning the shelf board 21 to its original position. First, the user rotates any part of the operating member 70 upward as shown by the arrow in Fig. 3. As a result, the spring members 40 connected to both ends of the operating member 70 are rotated upward against the biasing force of the leaf springs 45.

[0033] As shown in FIG. 10(a), when the front of the spring member 40 is rotated upward, the locking surface 55 of the locking portion 52 is moved downward, whereby the locking of the locking surface 55 with the locking block 60 is released. In this state, the shelf board 21 is unlocked, and the user can simply pull the operating member 70 forward as shown in Figure 10(b), thereby causing the shelf board 21 to be pulled forward via the slide rail 35 as shown in Figure 10(c). With the shelf board 21 pulled out, operations such as replenishing or replacing products on the shelf board 21 can be carried out efficiently.

[0034] To return the shelf board 21 to its original position, the user pushes the shelf board 21 backward as shown in Fig. 11(a). Then, as shown in Fig. 11(b), when the shelf board 21 is pushed in, the inclined surface 56 of the locking portion 52 comes into contact with the locking block 60. By further pushing the shelf board 21 in, the inclined surface 56 of the locking portion 52 moves along the locking block 60, and the spring member 40 is rotated against the biasing force of the leaf spring portion 45. As shown in FIG. 11(c), by further pushing the shelf board 21 in from this state, the inclined surface 56 of the locking portion 52 climbs over the locking block 60, whereby the locking surface 55 is locked into the locking block 60, and the shelf board 21 is locked. In this manner, by pulling out the operating member 70 and pushing in the shelf board 21, the shelf board 21 can be easily pulled out and pushed in.

[0035] As described above, in this embodiment, a shelf 21 on which goods are placed is installed inside the display room 20, the shelf 21 can be pulled out and moved to the outside of the display room 20, the shelf 21 is provided with a locking member 50 that locks the shelf 21 to a shelf support member 22 fixed to the display room 20 side, and an operating member 70 is provided at the front of the shelf 21 to unlock the locking member 50 and the shelf support member 22. Thus, the shelf 21 can be pulled out by releasing the lock between the locking member 50 and the shelf support member 22 with the operating member 70. As a result, the user is no longer required to perform complicated operations and can pull out the shelf 21 by simply operating the operating member 70 with one hand, thereby improving usability.

[0036] In addition, in this embodiment, spring members 40 are attached to both sides of the shelf board 21 so as to be freely rotatable in the vertical direction, and the locking member 50 is fixed to the spring members 40, and the spring members 40 are provided with leaf spring portions 45 that bias the locking member 50 into the locked state. This allows the locking member 50 to be held in a locked state by the leaf spring portion 45, and by rotating the spring member 40 against the biasing force of the leaf spring portion 45, the locking by the locking member 50 can be released.

[0037] In addition, in this embodiment, the shelf support member 22 has a locking block 60, and the locking member 50 has a locking surface 55 that engages with the locking block 60, and when the spring member 40 is rotated, the lock between the locking surface 55 of the locking member 50 and the locking block 60 is released. As a result, by rotating the spring member 40 against the biasing force of the leaf spring portion 45, the engagement between the engagement surface 55 of the lock member 50 and the engagement block 60 can be released.

[0038] In addition, in this embodiment, the operating member 70 is connected to the front end of each spring member 40, and when the operating member 70 is operated and the spring members 40 are rotated, the engagement between the engagement surface 55 of the locking member 50 and the engagement block 60 is released. As a result, by operating the operating member 70 to rotate each spring member 40, it is possible to release the engagement between the engaging surface 55 of the locking member 50 and the engaging block 60. Since the locking members 50 fixed to the spring members 40 can be released by operating the operating member 70, the shelf board 21 can be pulled out with a single intuitive operation.

[0039] In this embodiment, the operating member 70 is provided across the entire width of the front portion of the shelf board 21. As a result, the user can rotate the spring member 40 by operating any position in the width direction of the operating member 70, thereby releasing the engagement between the engagement surface of the lock member 50 and the engagement block 60.

[0040] In addition, in this embodiment, the locking member 50 has a positioning portion 51 that positions the locking member 50 relative to the locking block 60 when the locking surface 55 is engaged with the locking block 60, and has receiving portions 54 on both sides of the positioning portion 51 that receive the locking block 60. As a result, since receiving portions 54 for receiving the locking blocks 60 are provided on both sides of the positioning portion 51 of the locking member 50, it becomes possible for the locking member 50 to be applied to either the left or right spring member 40. As a result, the locking member 50 can be used as a common part for both the left and right spring members 40.

[0041] The present invention is not limited to the above-described embodiment, and various modifications and applications are possible without departing from the spirit of the present invention. [Industrial Applicability]

[0042] As described above, the showcase of the present invention does not require complicated operations and the shelf can be pulled out simply by the user operating the operating member with one hand, making it ideal for use as a showcase that can improve usability. [Explanation of symbols]
