Description

The present invention relates to a showcase that has a product placement section inside the case body on which products such as slide decks can be placed.

Conventionally, in stores such as supermarkets and convenience stores, there are many showcases that store products inside the case body while they are placed on a slide deck or the like. This slide deck is composed of a bracket member, a deck support frame, a variable plate, and an operating lever.

The bracket members are a pair of left and right brackets that are provided inside the case body, which has an opening on the front, and extend forward. The deck support frame is attached to the inside of the bracket members via a slider and can slide in the front-to-rear direction through the opening on the front of the case body. This deck support frame supports the deck, on which products are placed, so that its rear end can swing up and down.

The variable plate is attached to the deck support frame and can swing between a horizontal position and an inclined position. The operating lever is provided at the front end portion of the deck support frame so as to be slidable in the front-rear direction between a first switching position and a second switching position. This operating lever is provided with a guide pin, which enters a guide groove formed in the variable plate, and the operating lever engages with the variable plate. When the operating lever is placed in the first switching position, it places the variable plate in a horizontal position, while when placed in the second switching position, it places the variable plate in an inclined position.

In such a slide deck, the deck support frame is slid forward and the operating lever is placed in the second switching position, causing the variable plate to assume an inclined position, and then the deck support frame slides rearward, causing the variable plate, which is in an inclined position, to ride up onto a slide plate formed on the bracket member, thereby tilting the deck with its front edge lowered. This makes it easier to see the merchandise placed on the deck, and when an item placed at the front of the deck is removed, an item placed at the rear of the deck can be slid forward (see, for example, Patent Document 1).

JP 2020-185268 A

In the showcase described above, the operating lever and variable plate are engaged, and the variable plate, which is in an inclined position, rides up onto the slide plate, pushing up the deck and tilting the deck so that its front edge is lower. Therefore, when a product for sale is placed on the deck, the weight of the product acts not only on the variable plate but also on the operating lever that engages with the variable plate, and there is a risk that the engagement between the variable plate and the operating lever, which is established by inserting a guide pin into a guide groove, may be damaged.

In view of the above situation, the present invention aims to provide a showcase that can improve durability by preventing damage to components due to the weight of products placed on the loading plate when the loading plate is tilted so that the front edge is lower.

In order to achieve the above object, the showcase according to the present invention comprises a bracket member provided inside a case body having an opening on the front side in a manner extending forward; an auxiliary sidewall member attached to the inside of the bracket member via a slider and slidable in the front-rear direction between a front end position where the front end is disposed forward of the opening and a rear end position where the front end is disposed rearward of the opening; a loading plate whose front end is supported by the auxiliary sidewall member via a support shaft and whose rear end edge is arranged so as to be able to swing up and down relative to the auxiliary sidewall member around the support shaft; an arm member provided outside the auxiliary sidewall member so as to be able to swing between a horizontal position and an inclined position; and a first switching position and a second switching position at the front end of the auxiliary sidewall member. A showcase configured with a product placement section that is provided so as to be movable between a switching position, and a switching lever member that allows the arm member to assume a horizontal position when placed at the first switching position, and abuts against the arm member to place the arm member in an inclined position when placed at the second switching position, the product placement section is provided in a manner that protrudes outward from the outer side of the bracket member, and has a protrusion that inclines the placement plate so that the front edge is lowered when the arm member is placed in the inclined position, and when the auxiliary side wall member is placed at the rear end position with the arm member in the inclined position placed on the protrusion, the arm member and the switching lever member are separated.

The present invention is also characterized in that, in the above showcase, the protrusion comprises an axial portion provided on the outside of the bracket member in a manner that protrudes outward, and an annular roller member arranged so as to be rotatable around the central axis of the axial portion by inserting the axial portion into a hollow portion, and the arm member is placed in the inclined position on a portion of the peripheral surface of the roller member.

The present invention is also characterized in that, in the showcase, the arm member is supported by an inclined support member attached to the loading plate outside the bracket member via an arm support shaft so as to be swingable about the arm support shaft, and when the arm member is in the inclined position, the upper wall portion presses against the loading plate to incline the loading plate.

The present invention is also characterized in that, in the above-mentioned showcase, the product placement section is disposed on the inclined support member with a portion of the product placement section positioned outside the arm member, and is provided with a restricting member that restricts the arm member from deforming outward.

The present invention is also characterized in that in the showcase described above, when the auxiliary sidewall member slides from the front end position to the rear end position in the horizontal position, the arm member makes the loading plate horizontal without placing it on the protrusion.

The present invention is also characterized in that in the above showcase, the product placement section is a slide deck on which the placement plate is located at the very bottom of the case body and on which products are placed.

The present invention is also characterized in that in the above-mentioned showcase, the switching lever member is movable in the front-rear direction between the first switching position and the second switching position, which is located rearward of the first switching position.

According to the present invention, the product placement section is provided on the outside of the bracket member in a manner that protrudes outward, and includes a protrusion that tilts the placement plate so that the front edge is lower when the arm member is placed in an inclined position, and when the auxiliary side wall member is positioned at the rear end position with the inclined arm member placed on the protrusion, the arm member and the switching lever member are separated, so that the switching lever member can be set in a free state. As a result, when a product for sale is placed on the placement plate, the weight of the product for sale does not act on the switching lever member, and damage to the switching lever member, etc. can be prevented. Therefore, when the placement plate is inclined so that the front edge is lowered, damage to components due to the weight of the product placed on the placement plate can be prevented, and durability can be improved.

The second auxiliary sidewall mounting piece 262 is a flat portion extending downward from the front end of the lower end portion 261b of the second auxiliary sidewall base 261. This second auxiliary sidewall mounting piece 262 is disposed outside the upwardly extending extension end portion 252a of the first auxiliary sidewall mounting piece 252 and is attached to the first auxiliary sidewall mounting piece 252 via a connecting pin 262a. In this way, the second auxiliary sidewall member 26 is connected to the first auxiliary sidewall member 25.

The deck mounting support portion 263 is integrally provided at the upper end of the front end portion of the second auxiliary sidewall base 261, and has a deck mounting support extension portion 2631 and a deck mounting support base 2632. The deck mounting support extension portion 2631 is a flat portion that extends outward from the upper end of the front end portion of the second auxiliary sidewall base 261. The deck mounting support base 2632 is a flat portion that extends downward from the extending end portion of the deck mounting support extension portion 2631, and its inner surface faces a part of the outer surface of the second auxiliary sidewall base 261. A deck support through hole 2632a is formed in the center portion of this deck mounting support base 2632.

As shown in FIG. 11, in this type of auxiliary sidewall unit 20b, the first auxiliary sidewall member 25 is attached to the inside of the first base wall portion 211 of the first bracket member 21 via the first slider 31a, and the second auxiliary sidewall member 26 is attached to the inside of the second base wall portion 221 of the second bracket member 22 via the second slider 31b between the second bracket member 22 and the guide wall member 23. The first slider 31a and the second slider 31b are conventionally known, so a description thereof will be omitted. As a result, the auxiliary sidewall unit 20b (the first auxiliary sidewall member 25 and the second auxiliary sidewall member 26) can slide along the front-rear direction relative to the bracket unit 20a (the first bracket member 21 and the second bracket member 22).

Figures 12 and 13 are exploded perspective views of the tilt support unit 20c and its surrounding structure. As shown in Figures 12 and 13, the tilt support unit 20c is configured with a tilt support member 32 and an arm member 33.

The tilt support member 32 is formed, for example, from sheet metal, and is constructed by integrally molding the tilt support base 321, the first tilt support mounting portion 322, and the second tilt support mounting portion 323.

The inclined support base 321 is a long, flat plate-like portion that extends along the front-to-rear direction. This inclined support base 321 is attached to the lower part of the right side of the deck frame 41. The inclined support base 321 that constitutes the left deck support member 20 is attached to the lower part of the left side of the deck frame 41.

The first inclined support mounting portion 322 is a flat portion that extends downward from the outer edge of the front end portion of the inclined support base 321. A deck support mounting hole 322a is formed in the center of this first inclined support mounting portion 322.

The deck support shaft 34, which penetrates the deck support mounting hole 322a from the outside, is attached to the deck support through hole 2632a of the second auxiliary sidewall member 26 from the outside, so that the inclined support member 32 can rotate about the deck support shaft 34 relative to the second auxiliary sidewall member 26. The inclined support member 32 can also slide in the front-rear direction together with the second auxiliary sidewall member 26 on the outside of the second bracket member 22.

In other words, the loading plate 40 (deck frame 41) attached to the inclined support base 321 of the inclined support member 32 has its front end supported by the second auxiliary sidewall member 26 via the deck support shaft 34, and its rear end edge is arranged to be able to swing up and down relative to the second auxiliary sidewall member 26 around the deck support shaft 34, and is also able to slide along the front-to-rear direction. Here, when the auxiliary sidewall unit 20b equipped with the second auxiliary sidewall member 26 is arranged at the rearmost rear end position, the loading plate 40 is arranged at the rearmost storage position, and when it is arranged at the frontmost front end position, the loading plate 40 is arranged at the frontmost pull-out position.

The second inclined support mounting portion 323 is a flat portion that extends downward from the outer edge of the central portion of the inclined support base 321 in the front-to-rear direction.

The arm member 33 is formed, for example, from sheet metal, and is constructed by integrally molding the arm base 331, the first arm abutment piece 332, the second arm abutment piece 333, and the arm lower wall portion 334.

The arm base 331 is an elongated portion whose longitudinal direction is the front-to-rear direction. An arm support through hole 331a is formed in the center of the arm base 331 in the front-to-rear direction. In addition, an arm support restriction hole 331b having an elongated hole shape whose longitudinal direction is the up-down direction is formed on the front side of the arm support through hole 331a.

The first arm abutment piece 332 is formed by bending inward a tongue-shaped portion formed at the upper end of the arm base 331, further forward than the arm support restriction hole 331b.

The second arm abutment piece 333 is formed by bending inward a tongue-shaped portion formed at the upper end of the arm base 331 rearward of the arm support through hole 331a. The arm lower wall portion 334 is a flat plate-shaped portion formed by bending inward at a substantially right angle from the lower end of the arm base 331.

In this type of arm member 33, an arm support shaft 35 that passes through the arm support through hole 331a from the outside is attached to the second inclined support mounting portion 323, and an arm restriction shaft 36 that passes through the arm support restriction hole 331b from the outside is attached to the second inclined support mounting portion 323, so that the arm restriction shaft 36 is attached to the inclined support member 32 so as to be swingable around the arm support shaft 35 within a range in which it can move relatively through the arm support restriction hole 331b.

In more detail, the arm member 33 is swingably attached to the outside of the inclined support member 32, and is therefore swingably attached to the outside of the second auxiliary sidewall member 26 and to the outside of the second bracket member 22.

The inclined support member 32 of the arm member 33 is disposed on the second auxiliary sidewall member 26, so that the first arm abutment piece 332 can abut against the switching lever member 29 provided on the first auxiliary sidewall member 25. In other words, when the switching lever member 29 is disposed in the first switching position, the arm member 33 assumes a horizontal position as the arm restriction shaft 36 abuts against the lower edge of the arm support restriction hole 331b (see Figures 2 to 4). On the other hand, when the switching lever member 29 is disposed in the second switching position, the arm member 33 assumes an inclined position in which the arm restriction shaft 36 abuts against the upper edge of the arm support restriction hole 331b as the first arm abutment piece 332 abuts against the abutment member 298 and is pressed, and the arm member 33 assumes an inclined position in which the arm restriction shaft 36 abuts against the upper edge of the arm support restriction hole 331b and gradually inclines upward toward the rear.

A regulating member 37 is attached to the inclined support member 32. The regulating member 37 is formed, for example, from sheet metal, and is disposed on the rear side of the second inclined support mounting portion 323, with a downward extending portion 371 disposed outside the second inclined support mounting portion 323. When the arm member 33 is attached to the inclined support member 32 so that the arm member 33 is swingably attached, the downward extending portion 371 of the regulating member 37 is disposed outside the arm member 33 in such a manner that it faces a portion of the outer surface of the arm base portion 331 of the arm member 33.

Figure 14 is a side view of the slide deck 10 showing the state in which the mounting plate 40 is arranged in the storage position. As shown in this figure, when the mounting plate 40 is arranged in the storage position, the return grill 30 is located above the suction port 5. In other words, when the mounting plate 40 is arranged in the storage position, the ventilation hole portion 30a of the slide deck 10 communicates with the suction port 5. When the switching lever member 29 is arranged in the first switching position and the arm member 33 is in a horizontal position, the second arm abutment piece 333 is separated from the mounting plate 40, and the inclined support base portion 321 of the inclined support member 32 (deck frame portion 41) is placed on the second upper wall portion 223 of the second bracket member 22, so that the mounting plate 40 is in a horizontal state. In addition, the arm lower wall portion 334 of the arm member 33 is located below the roller member 24 of the bracket member.

By sliding the auxiliary sidewall unit 20b (first auxiliary sidewall member 25 and second auxiliary sidewall member 26) forward from this state, the loading plate 40 also slides forward while remaining horizontal, and the loading plate 40 is placed in the withdrawn position as shown in FIG. 15.

When the switching lever member 29 is moved from the first switching position to the second switching position as shown in FIG. 16 with the mounting plate 40 in the extended position, the circular sheet member 294a is exposed from the rear viewing hole 2532 and the abutment member 298 presses the second arm abutment piece 333. As a result, as shown in FIG. 17, the arm member 33 is in an inclined position in which the arm restriction shaft 36 abuts against the upper edge of the arm support restriction hole 331b, and the second arm abutment piece 333 abuts against the mounting plate 40.

When the auxiliary sidewall unit 20b (first auxiliary sidewall member 25 and second auxiliary sidewall member 26) is slid backward while the arm member 33 is in an inclined position, the arm lower wall portion 334 of the arm member 33 comes into contact with the roller member 24 while being placed on the peripheral surface of the roller member 24. At this time, the roller member 24 rotates clockwise as viewed from the right, following the backward movement of the arm member 33.

When the auxiliary side wall unit 20b is slid backward with the arm lower wall portion 334 placed on the peripheral surface of the roller member 24 in this manner, the second arm abutment piece 333 presses against the mounting plate 40, causing the rear end of the mounting plate 40 to be pushed upward.

As shown in FIG. 18, when the mounting plate 40 is placed in the storage position, the mounting plate 40 is inclined with the front edge lowered. In this case, the inclination angle of the arm member 33 in the inclined position becomes even larger, and the first arm abutment piece 332 of the arm member 33 and the abutment member 298 (switching lever member 29) are separated from each other.

When returning the loading plate 40 from the inclined state to the horizontal state, the loading plate 40 can be slid to the drawn-out position, the switching lever member 29 can be placed in the first switching position, and the arm member 33 can be placed in a horizontal position. Then, with the arm member 33 in the horizontal position, the loading plate 40 can be slid to the stored position, whereby the loading plate 40 can be placed in a horizontal position.

As described above, according to the showcase of the embodiment of the present invention, when the mounting plate 40 is in the storage position, i.e., the auxiliary side wall unit 20b is in the rear end position, with the inclined arm member 33 placed on the roller member 24, the slide deck 10 separates the arm member 33 from the switching lever member 29, so that the switching lever member 29 can be set in a free state. As a result, when a product for sale is placed on the mounting plate 40, the weight of the product for sale does not act on the switching lever member 29, and damage to the switching lever member 29 and the like can be prevented. Therefore, when the mounting plate 40 is inclined in such a manner that the front edge portion is lowered, damage to the components due to the weight of the product placed on the mounting plate 40 and the like can be prevented, and durability can be improved.

According to the above showcase, the shaft-shaped portion 241 provided on the second bracket member 22 in a manner protruding outward is inserted into the hollow portion 24a, and the annular roller member 24 arranged rotatably around the central axis of the shaft-shaped portion 241 tilts the mounting plate 40 in a manner that lowers the front edge when the arm member 33 is placed on a part of the circumferential surface in an inclined position. Therefore, when the arm member 33 slides in response to the sliding of the mounting plate 40, the roller member 24 that contacts the arm member 33 on a part of the circumferential surface rotates, thereby reducing the friction force generated between the arm member 33 and the arm member 33, and reducing the force required for operation. Moreover, wear and tear of the arm member 33 and the roller member 24 can be suppressed. Therefore, the operating force for tilting the mounting plate 40 can be reduced, and the service life can be extended.

According to the above showcase, the downward extending portion 371 of the restricting member 37 arranged on the inclined support member 32 is positioned outside the arm member 33 in a manner that faces a part of the outer surface of the arm base 331 of the arm member 33. Therefore, when a product for sale is placed on the loading plate 40 that is inclined so that the front edge portion is lowered, the arm member 33 can be restricted from deforming outward, suppressing deformation of the arm member 33 etc. and lengthening its service life.

The above describes a preferred embodiment of the present invention, but the present invention is not limited to this and various modifications can be made.

In the above-described embodiment, the roller member 24 is provided on the second bracket member 22, but in the present invention, it is not necessary for it to be a roller member 24, and it is sufficient for it to be a protrusion that is provided on the outside of the bracket member in a manner that protrudes outward and that tilts the mounting plate in a manner that lowers the front edge when the arm member is placed in an inclined position.

In the above-described embodiment, a slide deck 10 is shown as the product placement section, but in the present invention, the product placement section may be a product placement shelf.
