Abstract

PURPOSE:To provide a rack device attached simply not to be dropped out. CONSTITUTION:In a rack device having an L-shaped projection 11 on the lower surface of a rack plate 1 removably engaged with an L-shaped recess 21 on the upper surface of a bracket 2, a one step higher stage 21b is provided on the bottom at the corner side adjacent to an opening 21a in the recess 21, so that the engaging rack plate 1, while being lifted, is pushed to the stage 21b side and the tip of the projection 11 first rides on the stage 21b to be removed from the opening 21a. Since, however, the rack plate 1 is blocked from only the horizontal movement by the stage 21b when pushed to the state 21b side, the engagement of the projection 11 with the recess 21 is not broken even if the rack plate 1 is pushed in any directions when articles are put in and out, so that the rack plate 1 is prevented from dangerously getting out of a bracket 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shelf device in a showcase or the like.

[0002]

2. Description of the Related Art As shown in FIG. 3, an L-shaped concave portion 21 formed on an upper surface of a bracket 2 is engaged with an L-shaped projection 11 formed on a lower surface of a shelf plate 1 so as to be detachably attached. A shelf device T _B having such a structure is conventionally known.

In the shelf device T _{B having the} above structure, the shelf board 1
The flange 11a of the projection 11 is caught by the projection 21c of the recess 21 to prevent the shelf board 1 from falling off by simply dropping the projection 11 of the projection 11 into the recess 21 of the bracket 2 and then pulling the shelf board 1 forward (to the right in the drawing). Since it is designed, a shelf mechanism that does not easily fall off can be easily obtained.

However, in the above-structured shelving apparatus T _B , if the shelf board 1 is not pulled out sufficiently toward the front, the projections 11 and the recesses 21 will not be completely engaged, and the shelf board 1 will be simply the bracket 2. It is said that the shelf plate 1 easily rotates and falls forward when a force from above is applied to the part of the shelf plate 1 projecting from the tip of the bracket 2 since it is no different from the state where it is just placed on the shelf plate 1. There was a danger.

Particularly, in the case of the shelf device T _C disclosed in Japanese Patent Application Laid-Open No. 63-226309, which is used for a front open low temperature showcase installed in a store such as a supermarket, as shown in FIG. The center of gravity of the shelf board 1 is determined by the fact that the lighting lamp 3 that illuminates the bottom of the shelf board 1 is installed on the lower surface of the shelf board 1, and the price rail for holding the card with the product name, price, etc. Even if a large object is not placed on the shelf board 1 if the projection 11 and the recess 21 are not completely engaged with each other, the shelf board 1 will move to the bracket 2 if the projection 11 is incomplete. There was a problem that there was a high risk that it would rotate and fall.

Even when the shelves 1 are fully pulled out toward the front to completely engage the protrusions 11 and the recesses 21 when the shelves are installed, the shelves 1 may be deep in the case of loading or unloading the goods. When pushed in the left direction of the drawing), the protrusion 11 easily comes out of the recess 21, and there is a concern that it cannot be said that high safety is always maintained.

[0007]

Therefore, the present invention is to devise a shelving device which can be easily attached so as not to fall off, and in which the shelves are not likely to fall off when putting or taking out an item. Was strongly expected.

[0008]

As a concrete means for solving the above-mentioned problems of the prior art, the present invention provides an L-shaped concave portion formed on the upper surface of the bracket and an L-shaped concave portion formed on the lower surface of the shelf board.
A shelving device for a showcase or the like for engaging a character-shaped protrusion to prevent the shelving device from falling off, wherein the recess is formed to have a step at a corner-side bottom facing the opening. When,

A shelf device for a showcase having the above-described structure, in which the front end portion of the bracket is inclined so that the upper surface side projects forward and the lower surface side recedes, and the problems of the prior art are solved. Is.

[0010]

When engaging the L-shaped projection on the lower surface of the shelf with the L-shaped recess on the upper surface of the bracket, the tip of the L-shaped projection is opposed to the opening of the recess, and the shelf is provided at the bottom of the L-shaped recess by its own weight. When the shelf board is horizontally moved in the direction away from the step, the shelf board is disengaged from the step and falls into the lower part of the L-shaped recess.

When the shelf is engaged and installed, the tip of the L-shaped projection is placed on the step only when the shelf is lifted and pushed toward the step, and the shelf can be removed from the opening of the L-shaped recess. However, if you simply push the shelf towards the step, the L-shaped protrusion will hit the step and prevent horizontal movement. Even if it is pushed in any direction, the engagement relationship between the L-shaped projection and the L-shaped recess is not broken. Therefore, there is no danger that the shelves suddenly come off the brackets and fall.

In a shelf device having a bracket formed so that the upper surface side of the tip portion projects forward and the lower surface side recedes, not only is it possible to widely support the lower surface of the shelf board, but also the shelf board. There is no obstacle when installing a lighting device such as a fluorescent lamp on the lower side.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 1 and 2. _A shelf device T _{A according} to the present invention has a shelf board 1 and the shelf board 1 as a showcase (not shown). The shelf 2 is formed of a bracket 2 for fixing, and an L-shaped projection 11 formed on the lower surface of the shelf board 1 is engaged with an L-shaped recess 21 formed on the upper surface of the bracket 2 to form a shelf board. 1
Is detachably attached to the upper surface of the bracket 2,

The L-shaped concave portion 21 is provided with a raised step portion 21b at the bottom portion on the corner side facing the opening portion 21a,
An engagement recess 21d communicating with the opening 21a is provided below the protrusion 21c.

The L-shaped projection 11 and the L-shaped recess 2 are provided.
The dimensional relationship with 1 is that when the flange 11a at the lower end of the protrusion 11 passes through the opening 21a and descends to the step 21b, and the shelf board 1 is pulled forward (to the right in the drawing), the flange 11
a is disengaged from the stepped portion 21b and dropped into the lower recessed engaging recess 21d, so that even if the shelf board 1 is lifted up in this state, the flange 11a is not caught by the projection 21c and disengaged. Even if is simply pushed inward (to the left in the drawing), the lower end of the protrusion 11 hits the stepped portion 21b before the tip of the flange 11a comes out of the bottom of the protrusion 21c, and moves horizontally (to the left in the drawing). Are being blocked.

Further, the bracket 2 is formed in an inclined state in which the upper surface side on which the shelf board 1 is placed projects forward and the lower surface side recedes, which causes an obstacle when the illumination lamp 3 is installed below the shelf board 1. It does not become a structure. Further, with the above structure, the shelf board 1 is supported by the bracket 2 as far as possible to the front.

In this case, as the illuminating lamp 3, a conventionally known one is used as it is, and a snap-in type holder 32 having an arrow-shaped snap 31 is fixed to the reinforcing member 12 of the shelf board 1. By the elongated transparent cylinder 3
The fluorescent lamp 34 is attached to the lower end portion of the shelf board 1 via 3 to illuminate the lower side of the shelf board 1.

Reference numeral 4 is a price rail detachably attached to the end portion of the shelf board 1 for holding a card (not shown) on which a product name, price, etc. are written. The part 41 is formed on the front surface.

The back surface of the card holder 41 and the shelf board 1
The guard 5 is removably installed between the tip of the shelf and the fruits (vegetables, clothing, etc.) (not shown) arranged on the shelf 1 so that the guard 5 does not drop from the tip. Is becoming

The L-shaped concave portions 21 are formed at a plurality of positions (two positions in this case) of the bracket 2 so that the mounting position of the shelf plate 1 can be finely adjusted.

Further, the bracket 2 has fixing means 22a, 22b, 22c, 22d having a plurality of engaging concave and convex portions on the base side (left side in the drawing), and the engaging combination with the engaging hole on the showcase side is appropriately performed. Depending on the selection, the shelf board 1 can be fixed horizontally or can be fixed by tilting forward at a desired angle.

In the shelf device T _{A having the} above structure, the L-shaped projection 11 of the shelf board 1 is dropped into the L-shaped concave portion 21 of the bracket 2 attached to the showcase at a predetermined angle, whereby the shelf board 1 is detachably attached to the upper surface of the bracket 2.

That is, the L-shaped recess 2 of the bracket 2
When the flange 11a of the L-shaped projection 11 of the shelf board 1 is dropped into the opening 21a of the first plate, the flange 11a of the projection 11 hits the stepped portion 21b and the descent is interrupted. When 1 is moved to the front (to the right in the drawing) away from the stepped portion 21b, the flange 11a of the protrusion 11 falls from the stepped portion 21b to the position of the engaging recessed portion 21d lower by its own weight (for long-term use When either or both of the shelf plate 1 and the bracket 2 are deformed and the engagement in a perfect state cannot be expected only by lowering by the self weight, a force is applied from above to achieve a complete engagement. ).

If the shelving device T _{A according} to the present invention is used in the above-described engaged state, the flange 11a of the L-shaped projection 11 is projected from the L-shaped recess 21 even when the shelf plate 1 is lifted up. Since the portion 21c is not caught and does not come off, the shelf plate 1 does not drop off from the tip portion of the bracket 2 even when a product is placed on the tip side of the shelf plate 1.

Further, without raising the shelf board 1, the step portion 2
Even if horizontal stress is applied in the direction of 1b, the horizontal movement of the shelf board 1 is blocked by the stepped portion 21b, so that the engagement relationship between the protrusion 11 and the recessed portion 21 is not broken, so that the article is taken in and out. There is no need to pay any attention to the fact that the engagement relationship is not broken at the time.

When removing the shelf 1 from the bracket 2 which is engaged and installed, first, the shelf 1 is lifted from the back (left side in the drawing) to push the shelf 1 from the front (right side in the drawing) to the back, and L The flange 11a of the letter-shaped protrusion 11 is placed on the stepped portion 21b. Then, when the shelf board 1 is lifted again from this state, the flange 11a of the protrusion 11 is changed to the opening 21
Since it is pulled out from a, the engagement between the L-shaped projection 11 and the L-shaped recess 21 is released, and the shelf board 1 is removed from the bracket 2.

Since the present invention is not limited to the above embodiment, various modifications can be made. For example, since the L-shaped projection 11 and the L-shaped recess 21 need only be formed in the same direction so that they can engage with each other, the tip may be formed in the opposite direction to that of the embodiment, and as shown in the drawings. It is also possible to form in a right angle direction.

The L-shaped projection 11 formed on the lower surface of the shelf 1 may be formed on the main body of the shelf 1, or may be formed on a reinforcing member integrated with the main body. ..

[0029]

As described above, in the shelf device according to the present invention, the engaging and assembling is easy, and the shelf plate at the time of engaging and installing is pushed in any direction when the product is taken in and out. Even if there is, the stepped portion provided on the corner-side bottom facing the opening does not break the engagement relationship between the L-shaped projection and the L-shaped recessed portion, so there is no concern that it will fall off the bracket and suddenly fall. ..

Further, the upper surface side of the tip portion projects forward,
The shelf device having the brackets formed so that the lower surface side is inclined so as to be retracted can widely support the lower surface of the shelf plate, which not only enhances the safety, but also improves the safety of lighting equipment such as fluorescent lamps. It has many features such as no obstruction when mounted on the lower side, and has remarkable effects.
