Description

  The present invention relates to a sliding merchandise display shelf installed in a showcase.

In addition to fixed shelves, slide shelves taking into account the convenience of product replenishment are known as merchandise display shelves equipped in the showcase cabinet (see, for example, Patent Document 1 and Patent Document 2).
This slide-type product display shelf is connected via a telescopic slide rail between the left and right side edges of the shelf board and a bracket supported by a support column placed behind the inside of the showcase. It is held in the storage position pushed in, and the shelf board is pulled forward to perform the replenishment work when replenishing the product.
Next, the structure of this slide-type product display shelf is shown in FIGS. In the figure, 1 is a shelf plate of a product display shelf, 2 is a bracket, 3 is a slide rail connecting the left and right side edges of the shelf plate 1 and the bracket 2, 3L is a left slide rail, and 3R is a right slide rail. . Note that the slide rails 3L and 3R are common parts, and their directions are reversed left and right. Further, L in the figure is the depth length of the shelf board, T is a travel distance (movement stroke of the shelf board), and FIG. 2A shows a state in which the shelf board 1 is pulled out. 3a is a fastening screw for fixing the rail member of the slide rail 3 to the bracket 2, and 3b is a fastening screw for fixing the rail member to the shelf board 1.

Here, the product display shelf is relatively heavy (several tens of kilograms) of the products placed on the shelf 1 and overtravels at the position where the shelf 1 is pulled out. A ball bearing type slide rail (double slide type) is adopted that has an assembly structure in which ball bearings are combined with the three members (rail members) of the inner rail, outer rail, and middle rail. As shown in FIG.
3 (a) and 3 (b), 4 is an outer rail (a channel-shaped member having a C-shaped cross section) fixed to the bracket 2, and 5 is an inner rail (a member of the outer rail 4) fixed to the side edge of the shelf board 1. A channel member having the same C-shaped cross section), 6 is a middle rail (a channel member in which two substantially U-shaped cross sections are welded back to back), 7 is a ball bearing, 8 is a ball retainer, Ball guides formed on the upper and lower ends of the arc-shaped ball guide surfaces 4a, 4b, 5a, 5b formed on the upper and lower ends of the outer rail 4 and the inner rail 5 and on the upper and lower ends of the middle rail 6 after being held in a row by the retainer 8. It is interposed between the surfaces 6a and 6b. Although not shown, the slide rail is provided with a stopper to prevent the rail member from being disconnected at the stroke end by restricting the stroke that can be pulled out.

In addition, the slide product display shelf equipped in the showcase also includes a lock mechanism (for example, see Patent Document 1 and Patent Document 2) that locks the shelf board to the storage position, and the shelf board moves forward unexpectedly. In order to prevent the shelf board from moving forward from the storage position even if this locking mechanism is disengaged, the shelf board is attached with a slightly upward mounting angle on the slide rail. I try to return.
On the other hand, as described above, in the commodity display shelf in which the slide rail is angled at the front ascending and returned freely, it is natural that a detent means for holding the shelf board in the pull-out position is required. Otherwise, if the hand is released from the shelf pulled forward when replenishing the product, the shelf returns to the storage position due to its own weight. Although various detent mechanisms can be used for this detent means, simply locking the shelves by simply pushing the shelves without a special unlocking operation with a simple structure allows the shelves to be returned to the storage position. The following ball lock type stopper is employed in some slide rails as a slightly retaining and holding means.

  Next, the structure will be described with reference to FIG. That is, for the slide rail 3 shown in FIGS. 4A to 4D, the rear end portion of the inner rail 5 fixed to the shelf and the front end portion of the outer rail 4 fixed to the bracket (the outer rail 4 and the inner rail 5). Is a common part, and the slide rail is assembled by reversing the front-rear direction), and either an upper end surface or a lower end surface of the C-shaped channel is stamped into an arc-shaped ball. A protruding stopper 9 having a V-shaped cross section that protrudes inward from the guide surface so as to cross the row of ball bearings 7 is formed, and at the illustrated shelf board drawing position (over travel), the rear end portion of the inner rail 5 is formed. The formed stopper 9 protrudes between the ball arranged in the last row of the ball bearing 7 and the next ball, and the stopper 9 formed at the front end portion of the outer rail 4 is arranged in the front row. It is set so as to project between the LE and the next ball.

Thus, when the shelf plate tries to return to the storage position by its own weight from the drawer position, the stopper 9 comes into contact with the spherical surface of the ball bearing 7 arranged at the end of the ball row, and the shelf plate is locked and held at this position. Further, when the shelf plate is pushed by applying a force in this locked state, the stopper 9 gets over the ball bearing 7 arranged at the end (the ball bearing 7 rolls between the members constituting the slide rail 3). Thus, the channel-shaped member itself has some flexibility), and thereafter the shelf board can be moved to the storage position without being restrained by the stopper 9.

By the way, the slide-type product display shelf of the showcase constructed by adopting the above-described conventional slide rail with stopper has the following problems in terms of operation.
That is, the slide rail 3 having an assembly structure in which the stopper 9 is formed on one side of the upper and lower end surfaces of the C-channel outer rail 4 and inner rail 5 described in FIG. As shown, the direction of the rail is reversed left and right so that the rail member fixed to the shelf 1 is inward and the rail member 4 fixed to the bracket 2 is outward. As shown in FIGS. 4C and 4D, the left and right slide rails 3L and 3R are upside down in the position of the stopper 9 as shown in FIGS.
On the other hand, in the drawer position of the shelf board 1 shown in FIG. 2A, a large moment load acts downward on the slide rail 3 when the weight of the product placed on the shelf board 1 is also added. Looking at the degree of engagement between the stopper 9 of the inner rail 5 coupled to the shelf board 1 and the ball bearing 7 (resistance force against the pushing back operation of the shelf board) with this moment load applied, Compared to the slide rail 3L where the stopper 9 is positioned (see FIG. 4C), the slide rail 3R where the stopper 9 is positioned on the lower end side of the rail member 5 (see FIG. 4D) is stronger. .

For this reason, when the shelf board 1 drawn forward from the interior of the showcase is pushed into the storage position, the stopper 9 is released by the slide rail 3L connected to the left side of the shelf board 1 and the slide rail 3R connected to the right side. Due to different forces (forces required for the stopper to get over the ball bearing), there is a problem in the operation surface such that the pushing operation of the shelf board 1 cannot be performed smoothly. A similar problem occurs when the stopper 9 gets over the ball bearing 7 at the end position when the shelf plate 1 is pulled forward.
The present invention has been made in view of the above points, and its object is to solve the above-mentioned problems, and to show a slide-type product display shelf of a showcase supported by connecting slide rails to the left and right side edges of the shelf board, An object of the present invention is to provide a product display shelf for a showcase in which the structure of the slide rail is improved so that the latching and holding of the shelf plate at the drawer position and the pushing operation to the storage position can be performed smoothly.

  In order to achieve the above object, according to the present invention, there is a product display shelf that is arranged in a showcase cabinet and supported so as to be able to be pulled forward, and is arranged on the left and right side edges of the shelf board and behind it. In the case where the brackets supported by the inner and rear support columns are connected via a three-member slide rail combining ball bearings between the inner rail, outer rail and middle rail in the channel shape, the shelf board is pulled out As a detent means for locking and holding to, formed by punching the upper and lower end surfaces so as to protrude from the end of the channel-shaped outer rail and inner rail, which are assembly parts of the slide rail, toward the row of ball bearings Protruding stoppers with a V-shaped cross section are vertically symmetrical so that they protrude from both the upper and lower ball guide surfaces of the channel-shaped outer rail and inner rail. When the slide rails are shared, the direction of the slide rails of the three members is reversed inward and connected to the left and right edges of the shelf board, the left slide rail and the right slide rail The protruding stoppers having a V-shaped cross section are positioned symmetrically.

  According to the configuration in which the stoppers for the detent are formed on the upper and lower end surfaces of the rail member as described above, the ball bearing type slide rail consisting of three members is used as a common part, and the direction of the product display shelf Even in the state assembled to the left and right edges, the position of the stopper for detent is symmetrical with respect to the slide rail arranged on the left and right. As a result, when a moment load is applied to the slide rail at the position where the shelf is pulled out, the condition of the stopper is the same for the slide rails arranged on the left and right of the shelf. Can be done smoothly.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below based on the examples shown in FIGS. In the illustrated embodiment, members corresponding to those in FIG. 4 are denoted by the same reference numerals, and detailed description thereof is omitted.
That is, the configuration of the merchandise display shelf is the same as in FIG. 2, and the slide rail 3 connected to the left and right side edges of the shelf board 1 is basically the same as in FIG. As described above, each of the members (the above-mentioned members) has a V-shaped projecting stopper 9 formed so as to protrude from the ends of the outer rail 4 and the inner rail 5 which are assembly parts of the slide rail 3 toward the row of ball bearings 7. C-shaped channel) is formed in a vertically symmetrical position so as to protrude from both the upper and lower ball guide surfaces. The stopper 9 is stamped and formed on the upper and lower end surfaces of the channel-shaped member of the slide rail 3 by stamping.

  As a result, when the slide rail 3 is used as a common part and the direction of the member is reversed inward and connected to the left and right side edges of the shelf board 1, as shown in FIGS. 1 (c) and 1 (d), the left slide The stopper 9 is positioned symmetrically between the rail 3L and the right slide rail 3R. Therefore, even when a downward moment load is applied to the slide rail 3 at the position where the shelf board 1 is pulled out (see FIG. 2A), the degree of engagement between the stopper 9 and the ball bearing 7 is the left and right slide rails 3L and 3R. It becomes the same, and the release force of the ball lock is also balanced on the left and right. As a result, the shelf board can be smoothly pushed from the pull-out position to the storage position without any operability problems as described in FIG.
