Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a shelf slide device that allows a shelf to be freely pulled out from a storage box such as a closet.

[Background technology]

It was difficult to store bedding, etc. in the lower part of a normal closet. Therefore, a shelf sliding device has been proposed in which a sliding shelf is provided at the lower level of a closet, and the shelf is pulled forward from the closet to store bedding and the like. This device had a rail attached to one of the top surface of the base plate and the bottom surface of the shelf board, and a large number of rollers arranged in parallel on the other side to smoothly slide the shelf board.

However, since a large number of rollers are required to smoothly slide the shelf board, there is a problem that the mechanism becomes complicated.

[Purpose of invention]

The purpose of this invention is to provide a shelf sliding device that can smoothly slide a shelf using a simple mechanism.

[Disclosure of invention]

The shelf sliding device of this invention includes an I-shaped rail that is attached to the top surface of the main plate and extends in the depth direction, and a groove-shaped rail that is attached to the bottom surface of the shelf and extends in the depth direction, and the I-shaped rail is inserted into a groove. and,
First and second rollers are respectively attached to the inner surfaces of both rear flanges of the grooved rail and are located on opposite sides of the I-shaped rail through the web of the I-shaped rail; and a third roller that contacts the lower surface of the web of the grooved rail, the grooved rail is slidably held with respect to the I-shaped rail via these rollers, and the shelf board can be pulled out with respect to the base plate. At the same time, a protrusion is provided on the inner surface of the web of the groove-shaped rail, and is located close to the front of the third roller when the shelf board is pulled out from the base plate.

In this way, according to this invention, the groove rail attached to the bottom surface of the shelf board is held by only three rollers, so the mechanism is simple, and the groove rail attached to the bottom surface of the shelf board is held by only three rollers. First and second rollers are attached to the inner surfaces of both flanges of the rail to restrict the I-shaped rail from both sides, thereby preventing the shelf from wobbling and allowing smooth sliding.

In addition, when the shelf board is pulled out, a protrusion is provided on the inner surface of the web of the grooved rail that is located close to the front of the third roller, which prevents the shelf board from accidentally sliding. As a result, items can be safely taken in and out of the pulled-out shelf board.

Embodiment An embodiment of this invention will be described based on FIGS. 1 to 18. Fig. 1 is an explanatory diagram of the storage state of the shelves in this embodiment, Fig. 2 is an explanatory diagram of the shelf board pulled out state, Fig. 3 is a front view of the state shown in Fig. 1, and Fig. 4 is a horizontal cross-section thereof. It is a diagram.

As shown in FIGS. 1 to 3, this shelf sliding device has an I-shaped rail 3 that extends in the depth direction attached to the top surface of the main plate 1, and the I-shaped rail 3 that extends in the depth direction on the bottom surface of the shelf board 2. At the same time, as shown in FIG. 4, both flanges 4a,
First and second rollers 5, respectively, are provided on the inner surface of 4b.
6 and the web 3 at the front of the I-shaped rail 3.
A with a third roller 7 attached thereto.

As shown in FIG. 1, the base plate 1 is the base plate of a storage box 8 such as a closet, and is installed on an architrave 10, and a back plate 9 is attached to the back surface.

The grooved rail 4 has a shape shown in FIG. 5,
Both flanges 4a, 4 facing each other of this grooved rail 4
At the rear of b, there are a pair of roller mounting holes 11, 11 shifted in position in the longitudinal direction and these holes 11, 1.
Through holes 12, 12 are provided opposite to 1, into which a driver bit (not shown) for mounting a roller is inserted. FIG. 6 shows the roller mounting hole 11,
11 shows a state in which the first and second rollers 5 and 6 are attached. In addition, these rollers 5,
A pair of stoppers 27, 27 are provided on both flanges 4a, 4b in front of the groove 6 (FIG. 5).

Holes 13 for attaching to the shelf board 2 are bored in the web 4c of the grooved rail 4 by burring M6 tapping or the like (see FIG. 7). The groove-shaped rail 4 is attached to the shelf board 2 as shown in FIG.
The mounting screw 15 is inserted through the screw insertion hole 14 provided in the cap 1, and the upper part is fixed by tightening it.
Block with 6. In FIG. 8, 33 is an S washer.

Further, as shown in FIG. 5, the inner surface of the web 4c of the grooved rail 4 is provided with a first protrusion 17 and a second protrusion 18 for use as a stopper, which are punched (or squeezed) into the groove. (See Figure 9).
The positions and functions of these protrusions 17 and 18 will be described later.

An I-shaped rail 3 engaging such a channel rail 4 is shown in FIGS. 10 and 11. That is,
The I-shaped rail 3 is formed into an I-shape by overlapping a pair of substantially L-shaped members 31 and 32, and the front end of the upper flange 3a is cut out. This is to bring the upper part of the third roller 7 into contact with the inner surface of the web 4c of the grooved rail 4 as shown in FIG. It's for a reason.

Also, at the rear of the rollers 7 on the web 3c of the I-shaped rail 3, stoppers 25 for preventing the grooved rail 4 from coming off are cut and raised on both sides (FIG. 11). Furthermore, the lower flange 3b has mounting holes 2 for fixing to the base plate 1 by nailing or the like.
6 is formed.

Further, as shown in FIG. 12, an L-shaped stopper 19 is fixed by welding or the like on the upper flange 3a at the rear end of the I-shaped rail 3, and a cushion material 23 such as rubber is attached to the front surface of the rising piece. is installed. Also, instead of this stopper 19, a first
As shown in FIG. 3, the rear end of the upper flange 3a can be raised upward to form a stopper 19', and a cushion member 23' can be attached to the front surface of the stopper 19'.

When storing the shelf board 12 in the storage box 8,
As shown in FIG. 14, the sliding of the grooved rail 4 is stopped when it comes into contact with the cushion material 23 of the stopper 19 provided at the rear end of the I-shaped rail 3. At this time, the first protrusion 17 provided on the grooved rail 4 climbs over the roller 7 at the front of the I-shaped rail 3 and passes through the roller 7.
The vehicle is configured to stop at a position close to the vehicle. Therefore, the shelf board 2 is maintained in its stored state and is prevented from sliding inadvertently.

On the other hand, when pulling out the shelf board 2 from the storage box 8, with the shelf board 2 completely pulled out, as shown in FIG. The slide of the shelf board 2 is stopped by the provided stopper 27. In addition,
28 is a cushion material such as rubber attached to the stopper 25.

When the shelf board 2 is pulled out, the 16th
As shown in the figure, the second protrusion 18 provided on the grooved rail 4 is configured to ride over the roller 7 of the I-shaped rail 3 and stop at a position close to the front thereof. Therefore, as shown in FIG. 17, the shelf board 2 is prevented from returning unintentionally from the pulled-out state, and as a result, items can be safely taken in and out of the shelf board 2.

FIG. 18 shows an example of the use of the shelf slide device of this embodiment, in which a side plate 20 and a back plate 21 are respectively erected on both sides and the rear of the shelf 2, and a chest of drawers 22 is placed inside. There is. Therefore, when using the chest of drawers 22, the shelf board 2 is pulled forward from the storage box 8, so that items can be put in and taken out of the chest of drawers 22 in a very comfortable posture.

[Effect of idea]

According to this invention, the mechanism is simple because the grooved rail attached to the bottom surface of the shelf is held by only three rollers, and both flanges of the grooved rail attached to the bottom surface of the shelf are Since the first and second rollers are attached to the inner surface and the I-shaped rail is regulated from both sides, rattling of the shelf board is prevented and smooth sliding is possible.

In addition, when the shelf board is pulled out, a protrusion is provided on the inner surface of the web of the grooved rail that is located close to the front of the third roller, which prevents the shelf board from accidentally sliding. As a result, items can be safely taken in and out of the pulled-out shelf board.
