BACKGROUND OF THE INVENTION
The present invention relates to a display shelf mounting structure for a freezer / refrigerated showcase.
[0002]
[Prior art]
For example, FIG. 4 shows a frozen and refrigerated showcase for storing and displaying nutritional drinks and soft drinks. This is a showcase main body 1 formed of a heat insulating wall having an opening 2 for entering and exiting products. Is divided into partition plates 3 and formed into a product storage 4 and a cold air circulation duct 6. A machine room 7 is provided below the showcase body 1. A condenser that constitutes the cycle, a blower for the condenser, and a compressor are disposed, and a cooler that constitutes a refrigeration cycle together with the condenser and the like and a blower 5 for the cold air circulation are disposed in the cold air circulation duct 6. ing.
[0003]
Then, the cool air sucked into the cool air circulation duct 6 by the blower 5 and cooled by the cooler is blown out from the upper air outlet 8 to form a cool air curtain in the opening 2 so as to form a display shelf in the product storage 4. The product placed on 9 is kept cold and the outside air is prevented from entering the product storage 4 through the opening 2.
[0004]
In the commodity storage 4, display shelves 9 are detachably disposed in a plurality of stages via shelf receivers 10 attached to the partition plates 3 disposed on the back of the commodity storage 4. The display shelf 9 has a mounting structure that prevents the display shelf 9 from moving forward when a customer sorts or takes out products on the display shelf 9.
[0005]
Conventionally, for example, as shown in FIG. 5, this mounting structure is formed by forming a notch recess 18 in the shape of an L in the vicinity of the front end and the vicinity of the rear end of the shelf receiver 10, and the lower surface of the display shelf 9. An L-shaped locking projection 15 is provided so as to project downward from the top, and the locking projection 15 is locked to the notch recess 18 to fix the display shelf 9 to the shelf holder 10.
[0006]
In order to insert the locking projection 15 into the notch recess 18, the horizontal portion of the locking projection 15 is positioned above the opening of the notch in the notch 18 as shown in FIG. 6 (FIG. 6A). After that, if the display shelf 9 is dropped vertically downward as it is, the horizontal portion of the locking projection 15 is inserted into the cutout recess 18 from the opening of the cutout of the cutout recess 18 and the locking projection 15 is horizontally aligned. The portion hits the horizontal bottom of the notch 18 (state shown in FIG. 6B).
[0007]
From this state, the display shelf 9 is moved forward, the locking projection 15 is slid at the bottom of the recess 18 and the tip of the locking projection 15 is inserted into the space formed at the tip of the recess 18. Then (the state of FIG. 6C), the display shelf 9 is locked to the shelf support 10 in a state where the upward movement is prevented.
[0008]
[Problems to be solved by the invention]
Thus, if the display shelf 9 is placed on the shelf receiver 10 in a state of being pulled forward, the locking projection 15 will not fit into the notch recess 18 and will not come off the shelf receiver 10. 6 (d), for example, when the display shelf 9 is pushed rearward when goods are put in and out, the locking projection 15 moves backward in the notch recess 18, and as a result, the tip of the locking projection 15 and The fitting with the tip of the notch recess 18 is released.
[0009]
In this state, if a load from above is applied to the front side of the display shelf 9 for some reason, the rear portion of the display shelf 9 may be lifted off the shelf holder 10 and fall off. In particular, commodities are often stacked on the front part of the display shelf 9 in order to increase the display effect. In such a case, the rear part of the display shelf 9 is lightened, so that this part is easily lifted.
[0010]
Further, when the display shelf 9 is set at a predetermined position of the shelf holder 10, it is necessary to move the display shelf 9 forward after inserting the locking projection 15 into the notch 18, and the mounting work. Not good.
[0011]
The object of the present invention is to solve the disadvantages of the conventional example, and in the display shelf fixing structure for locking the display shelf to the shelf support, the display shelf is not affected even if a force is applied to the display shelf to move backward on the shelf support. If it is difficult to drop off the shelf holder and there is no force to push backward, the display shelf will automatically return to its original position, improving safety, and using the display shelf as a shelf holder. To provide a display shelf mounting structure for a refrigerated showcase that can be automatically set at a predetermined locking position and can improve the mounting workability if the locking protrusion is inserted into the notch recess when mounting. is there.
[0012]

[Means for Solving the Problems]
In order to achieve the above object, according to the present invention, first, the interior of a showcase body formed by a heat insulating wall having an opening for entering and exiting a product is partitioned by a partition plate, and a product storage box, a cold air circulation duct, The shelf holder is fixed to the back side in the product storage, and the L-shaped locking projection formed on the lower surface of the display shelf is engaged with the notch recess formed in the upper part of the shelf receiver. A display shelf is detachably attached to the top, the front side of the notch recess formed in the upper part of the shelf receiver is formed in a horizontal part, the rear side of the bottom part is formed in an inclined part, and the entire notch recess is substantially L-shaped. In the display shelf mounting structure of the formed refrigerator-freezer showcase, a step portion is provided on the inclined portion of the notch recess.
[0013]
As a result, when the display shelf is mounted on the shelf support, the locking protrusion slides along the inclined portion formed in the notch recess only by dropping the locking protrusion into the notch recess. Can be set at a predetermined position in the notch and the display shelf can be automatically fixed at a predetermined position of the shelf holder.
[0014]
In addition, even if the display shelf is pushed back and moved when the product is put in and out after being fixed in place, if the pressing force disappears, the locking projection will move forward along the inclined part of the notch recess. The display shelf returns to the predetermined position of the shelf holder. Therefore, the display shelf moves backward, and in this state, it is possible to minimize the rear portion of the display shelf from being lifted by the force from above applied to the display shelf, and the display shelf being removed.
[0015]
Furthermore, even when the display shelf is pushed backward to move, the locking projections move backward along the inclined portion and then hit the stepped portion, and further movement is prevented at this point. The locking projection is more difficult to drop from the notch recess.
[0016]
[0017]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a side view showing an embodiment of a display shelf mounting structure for a refrigerated showcase according to the present invention. The entire structure of the refrigerated showcase is the same as that already described with reference to FIG. To do.
[0018]
The display shelf 9 of the present invention is also detachably attached on the shelf receiver 10 attached to the front side from the rear partition plate 3 in the product storage 4 of the showcase. A notch recess serving as a locking portion is formed in the upper portion, a locking projection 15 is provided on the display shelf 9 side downward from the lower surface thereof, and the locking projection 15 is locked in the notch recess. The structure in which the display shelf 9 is fixed to the shelf holder 10 and the structure in which the locking protrusion 15 is formed by an L-shaped protrusion are the same as those in the prior art.
[0019]
A plurality of notch recesses are formed in the vicinity of the front end and the vicinity of the rear end of the upper portion of the shelf support 10, respectively, but the notch recess 17 formed in the vicinity of the front end is formed in a substantially L shape as shown in FIG. The bottom front side is formed in the horizontal portion 17a, the bottom rear side is formed in the inclined portion 17b following the notch opening 17e, and a step portion 17c is formed by a vertical portion in the middle of the inclined portion 17b. A void 17d formed at the tip is used as an engaging portion into which the tip of the locking projection 15 is inserted.
[0020]
A plurality of notch recesses 16 are also formed in the vicinity of the rear end. The shape of the notch recess 16 is generally the same as that of the notch recess 17, but the width of the opening 16e is narrower than the width of the opening 17e of the notch 17 and the depth of the space 16d is notched. It was formed larger than the depth of the void 17d of the recess 17.
[0021]
In FIG. 1, 11 is an illumination lamp such as a fluorescent lamp attached to the lower surface of the front portion of the display shelf 9 by an attachment member 12 that also serves as a reinforcing member, 13 is a price plate, and 14 is a drop of a product displayed on the display shelf 9. The shelf guard for preventing is shown.
[0022]
A method of attaching the display shelf 9 to the shelf holder 10 will be described with reference to FIG. 2 taking as an example a case where the locking projection 15 is engaged with a notch recess 17 provided near the front end. If the locking projection 15 is positioned in the vicinity of the opening 17e of the notch recess 17 (state of FIG. 2A) and the horizontal portion at the tip of the locking projection 15 is inserted into the recess from the opening 17e, the locking projection 15 As shown in FIG. 2 (b), the tip of the slide slides downward under its own weight along the inclined portion 17b.
[0023]
As a result, as shown in FIG. 2C, the tip of the locking projection 15 is dropped onto the horizontal portion 17a and enters the void 17d. In this state, the locking projection 15 and the notch recess 17 are engaged, and the display shelf 9 is fixed to a predetermined position of the shelf holder 10.
[0024]
The notch recess 16 provided in the vicinity of the rear end is similarly engaged with the locking projection 15, but the opening 16 e of the notch recess 16 is narrower than the opening 17 e of the notch recess 17. When attaching the display shelf 9 to the shelf holder 10, as a sequence, the locking protrusion 15 is first locked to the notch recess 16 provided in the vicinity of the rear end, and then the notch recess provided in the vicinity of the tip. 17 is locked.
[0025]
In this state, when the display shelf 9 is pushed rearward by taking in / out the product, the locking projection 15 moves rearward along the horizontal portions 16a and 17a of the notches 16 and 17, and further into the inclined portions 16b and 17b. However, if the backward pressing force disappears at this stage, the locking projection 15 moves forward again along the inclined portions 16b and 17b due to the weight of the display shelf 9 and the product on it. Then, it enters the empty spaces 16d and 17d and returns to a predetermined position. Therefore, even if the display shelf 9 is pushed rearward and the locking projection 15 reaches the vicinity of the openings 16e and 17e of the notches 16 and 17, the display shelf 9 is prevented from being detached from the shelf holder 10 from this state. Can be prevented.
[0026]
Further, when the locking projection 15 moves rearward along the inclined portions 16b and 17b as described above, the vertical step portions 16c and 17c are provided in the middle of the inclined portions 16b and 17b. The protrusion 15 collides with the step portions 16c and 17c and is prevented from further moving backward, and the locking protrusion 15 is prevented from coming out of the notches 16 and 17.
[0027]
Further, when a load from above is applied to the front portion of the display shelf 9 in a state where the display shelf 9 is pushed rearward, especially when many products are displayed on the front portion of the display shelf 9. Although the rear part of the shelf 9 is lighter, the rear part can be lifted easily. However, since the opening 16e of the rear notch recess 16 is narrow, the locking protrusion 15 moves further rearward at the step part 16c. In the state in which is blocked, there is no possibility that the locking projection 15 comes out of the opening 16e.
[0028]
Therefore, even if the front locking projection 15 is removed from the notch recess 17, the rear locking projection 15 does not come off from the notch recess 16, and the display shelf 9 is not lifted off from the shelf holder 10 and dropped off.
[0029]
In order to remove the display shelf 9 from the shelf holder 10, the display shelf 9 is moved slightly rearward, the front locking projection 15 is removed from the notch recess 17, and then the rear locking projection 15 is notched. What is necessary is just to remove from 16 and raise the display shelf 9. FIG.
[0030]
【The invention's effect】
As described above, the display shelf mounting structure for a refrigerator-freezer showcase according to the present invention firstly partitions the interior of the showcase body formed by a heat insulating wall having an opening for entering and exiting goods with a partition plate. An L-shaped engagement formed on the lower surface of the display shelf in a notch recess formed on the back side of the product storage, formed in a product storage and a cold air circulation duct; The display shelf is detachably attached to the shelf receiver by engaging the stop projection, the bottom front side of the notch recess formed in the upper portion of the shelf receiver is formed in the horizontal portion, and the rear side of the bottom portion is formed in the inclined portion. In the display shelf mounting structure of the refrigerated refrigerated showcase in which the entire recess is formed in a substantially L shape, A step portion was provided on the inclined portion of the notch recess.
[0031]
As a result, when the display shelf is mounted on the shelf support, the locking protrusion slides along the inclined portion formed in the notch recess only by dropping the locking protrusion into the notch recess. Can be set at a predetermined position in the notch and the display shelf can be automatically fixed at a predetermined position of the shelf holder.
[0032]
In addition, even if the display shelf is pushed back and moved when the product is put in and out after being fixed in place, if the pressing force disappears, the locking projection will move forward along the inclined part of the notch recess. The display shelf returns to the predetermined position of the shelf holder. Therefore, the display shelf moves backward, and in this state, the rear portion of the display shelf is lifted by applying a force from above to the end row shelf, so that the display shelf can be minimized.
[0033]
Further, by providing a stepped portion on the inclined portion of the notch recess , even when the display shelf is pushed rearward and moved, the locking protrusion moves backward along the inclined portion, Since this bumps into the part and further movement is prevented at this point, the locking projection is cut out and it is more difficult to drop out of the recess.
