Abstract

PURPOSE:To enable both the fixation of a temporary position and the prevention of dropping-out under the drawn-out condition by sandwiching a guide roller with a pair of projections of a movable rail from front and rear to regulate the forward and backward movement of a slide rack and further regulate such movement with a slide member and stop member making contact with each other even if a force of drawing out the rack forward acts. CONSTITUTION:A movable rail 2 is supported by a guide roller 13 of a fixed rail 1, and a slide member 23 by a support piece 22 and guide piece 12 respectively to be drawn out forward so that the front side projection 24 of a pair of projections 24, 25 completes the drawing-out operation by a moderate feeling given from the projection 24 overriding the guide roller 13. Thus, a slide rack is stopped with the guide roller 3 bending sandwiched by a pair of the front and rear projections 24, 25. When a pair of both projections 24, 25 are vigorously drawn out to override the guide roller 13, the front end face of the slide member 23 is moved into contact with the front side stopper member 14 right after the rear side projection 25 overrides the guide roller 13 to reach the final condition, so that the further forward movement is regulated.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to so-called zero
This invention relates to a support device for a sliding shelf on which a keyboard or the like of an All-in-one device is placed.

[Conventional technology]

For example, as a shelf on which a keyboard of a word processor or the like is placed, a shelf B having a sliding shelf A incorporated in its lower part as shown in FIG. 6 is known. In this shelf B,
A word processor body W is placed on the top surface of shelf B, and a keyboard I (is placed on the slide shelf).
The keyboard K can be put into a used state by pulling out the keyboard, and the keyboard K can be put into a stored state by putting the sliding shelf A into a stored state.

2. Description of the Related Art Conventionally, as a support device for a slide shelf for a keyboard, one in which a shelf board is slidably supported by a pair of guide rails is generally known.

[Problem to be solved by the invention]

In the above-mentioned conventional keyboard sliding shelf support device, a stop is generally provided to prevent the sliding shelf from falling when the sliding shelf is pulled out forward from the drawn-out state, but it restricts movement from the drawn-out state to the back. There is no means provided to do so. Therefore, if some pressing force is suddenly applied to the sliding shelf during key operations on the keyboard, the sliding shelf will slide toward the back. In this case, there is a risk that the text that has already been input will be erased by operating the key 21.

For this purpose, a support device shown in FIG. 7 can be considered as a structure that can be fixed at a low position in the drawn-out state. This support device consists of a fixed rail 1a and a movable rail 2a, the fixed rail 1a is provided with a band-shaped guide piece 12a and a guide roller 13a at its front end, and the movable rail 2a is provided with a guide roller 13a at its rear end. A slide portion 23a guided and supported by the guide piece 12a, a band-shaped support piece 22a guided and supported by the guide roller 13a, and a pair of convex portions 24a and 25a formed at predetermined positions of the support piece 22a. is provided. The pair of protrusions 24a and 25a are arranged so as to sandwich the guide roller 13a from the front and back when the slide shelf A is pulled out. movement is regulated.

However, since this support device is not provided with a final pulling-out prevention means, when the sliding shelf is pulled out with a relatively strong force, the pair of convex portions 24a, 25a
There is a risk that both of them will get over the guide roller 13a, and the slide shelf may fall off. Therefore, it is conceivable to form a protruding stopper on the fixed rail 1a to restrict the movement of the slide member 23a of the movable rail 2a.

However, if, for example, a stopper for regulating the movement of the slide member 23a in the pulled-out state is integrally formed on the guide piece 12a of the fixed rail 1a, the slide member 23a may sometimes be attached to the guide piece 12a when assembling the support device. In addition, the pair of protrusions 2 of the moving rail 2a
4a and 25a, and there is a possibility that their sliding movement will be inhibited. Furthermore, if the protrusion is formed after the extrapolation operation, it becomes impossible to pull out the slide shelf.

Therefore, in the support device shown in Fig. TS7, it was not possible to simultaneously fix the temporary position of the slide shelf in the drawn-out state and prevent it from being pulled out ultimately.

The present invention has been made in view of the above circumstances, and provides a support device for supporting a slide shelf for a keyboard, which is capable of both fixing the position of the slide in the pulled-out state and preventing the slide from falling. The purpose is to provide a shelf support device.

[Means to solve the problem]

In order to achieve the above object, claim 1 of the present invention includes a moving rail attached to both sides of a sliding shelf, and a support that slidably engages with the moving rail and supports the sliding shelf. The fixed rail has a band-shaped guide piece projecting toward the slide shelf, and a guide roller rotatably attached to the front end of the slide shelf, and the movable rail is a band-shaped support piece that protrudes toward the support body and whose lower surface is supported by the guide roller, a pair of convex portions that are formed to protrude downward on this support piece, and a guide piece of the fixed rail that is sandwiched therebetween. and a sliding member that faces each other in the vertical direction and moves along the guide piece, and the pair of protrusions are arranged so as to engage with the guide roller while sandwiching the guide roller from the front and back. The interval is set, and the pair of protrusions are arranged so as to engage with the guide roller when the slide shelf is pulled out to the use position in front of the support, and the guide piece of the fixed rail has a A stopper member is removably attached to contact the slide member of the moving rail to prevent the slide shelf from moving forward when the slide shelf is pulled forward from the use position. did.

Moreover, in claim 2. The stopper member was constituted by a screw.

[Effect]

According to the configuration of claim 1, when the slide shelf is in the drawn-out state, the pair of convex portions of the moving rail sandwich the guide roller from the front and back, so that the slide shelf is restricted from moving in the front and rear direction, and the movement of the slide shelf is restricted to a predetermined position. It can be temporarily fixed in the drawn state. Moreover, even if a force is applied to pull the slide shelf further forward than in the pulled-out state, the slide member and the stopper member come into contact with each other and prevent further movement, ensuring that the slide shelf does not fall out. It can be prevented.

In addition, sometimes the moving rail can be easily assembled to the fixed rail by removing the stopper member and inserting the sliding member of the moving rail onto the guide piece of the fixed rail. When pulling out the
This can be easily done by removing the stopper member.

Also, according to the structure of claim 2. Since the stopper member is constituted by a screw, the stopper member can be easily attached and detached.

〔Example〕

In FIGS. 1 and 2, the support device for the sliding shelf is composed of a fixed rail 1 and a movable rail 2. As shown in FIG.

The fixed rail 1 is composed of a strip-shaped mounting piece 11, a strip-shaped guide piece 12 protruding inward from the mounting piece 11, a guide roller 13, and a pair of stopper parts 4A14.15. Ru. The mounting piece 11 and the guide piece 12 are made of a predetermined strip material and have a cross-sectional shape of approximately L, excluding the front end.
It is integrally formed by bending it into a letter shape.

The guide roller 13 is attached to the inner surface of the front end portion 110 of the mounting piece 11 so as to be rotatable around a horizontal axis.
1 is formed with a screw hole 112 through which a screw 111 for installation is inserted. The stopper members 14 and 15 are constituted by ready-made screws with a screw head H of a predetermined size, and these screws are located at predetermined positions at the front and rear of the guide piece 12.
Threaded holes 121, 122 for attaching collar members 14, 15 are formed therethrough.

The moving rail 2 includes a mounting piece 21, a support piece 22 projecting outward from the mounting piece 21, a slide member 23 provided at the rear end of the mounting piece 21, and a pair of convex portions 24.
．． It consists of 25 etc.

The mounting piece 21 and the support piece 22 are integrally formed by bending a predetermined strip material so that the cross-sectional shape is approximately L-shaped.

The slide member 23 includes a pair of slide pieces 231 and 232 that are vertically opposed to each other as shown in FIGS. 1 and 3.
The pair of slide pieces 231 and 232 protrude outward from the mounting piece 21, and are provided so that the distance between them is slightly larger than the thickness of the guide piece 12 of the fixed rail 1. A pair of convex portions 24 and 25 are formed at predetermined positions at the rear of the support piece 22 to protrude downward at predetermined intervals. Also, the mounting piece 21 has screws 211 for mounting.
A screw hole 212 is formed through the screw hole 212 for insertion.

As shown in FIGS. 1 and 4, the movable rail 2 has the guide piece 12 of the fixed rail 1 sandwiched between the pair of slide pieces 231 and 232, and the lower surface of the support piece 22 guides the fixed rail 1. It is supported by rollers 13. The distance between the pair of convex portions 24 and 25 is set such that both of the pair of convex portions 24 and 25 and the guide roller 13 are in contact with each other while sandwiching the guide roller 13 from the front and back. Also, the pair of convex portions 24 and 25 are the guide roller 1.
The formation positions of the convex portions 24 and 25 are set so that the slide shelf A is in a drawn-out state with the slide shelf A sandwiching the slide shelf A from the front and back.

The slide member 23 and the front stopper member 14 are in the pulled-out state of the slide shelf (the state shown by the solid line in FIG. 1).
At the position where the slide shelf is further pulled forward (to the left in FIG. 1) and the rear convex portion 25 has climbed over the guide roller 13 (see the three-dot chain line in FIG. 1), the front end surface of the slide member 23 is The stopper member 4 is in contact with the stopper member 4, and the forward movement of the slide shelf is restricted by contacting the stopper member 4. Further, the rear stopper member 15 connects the rear end surface of the slide member 23 with the rear stopper member 15 when the slide shelf is in a predetermined storage state. - The slide shelf is arranged so that rearward movement of the slide shelf is restricted by contacting the flange member 15 with each other.

The front stopper member 14 is screwed into the guide piece 12 from below, and its length is set so that the tip of the threaded portion does not protrude from the upper surface of the guide piece 12.

In the sliding shelf support device described above, the fixed rail 1 is attached to the shelf body B (see FIGS. 1 and 6) with screws 111 with the rear stopper member 15 screwed into the rear screw hole 122 in advance. There is. In order to support the slide shelf A to which the movable rail 2 is attached to the fixed rail 1, first insert the rear end of the slide shelf into the shelf body from above the guide roller 13 as shown in FIG. Then, place the support piece 22 on the upper surface of the guide roller 13 (see the solid line in the figure). Next, by pushing the slide shelf in this state, the movable rail 2 moves rearward while the lower surface of its support piece 22 is rotationally supported by the guide roller 13, and the guide piece 2 is placed between the pair of slide pieces 231 and 232. enters. As a result, the slide shelf is supported by two points, the lower slide piece 232 and the guide roller 13 (see the two-dot chain line in the figure).

Thereafter, by screwing the front stopper member 14 into the front screw hole 121 from below, the assembly of the slide shelf A to the shelf body B is completed.

In this slide shelf support device, when the slide shelf A is pushed into the shelf body B, the rear end surface of the slide member 23 of the movable rail 2 comes into contact with the rear stopper member 15 of the fixed rail 1, and The above backward movement is regulated, and as a result, the sliding shelf is placed in a predetermined storage state (
(state shown by the two-dot chain line in FIG. 1).

Conversely, when the slide shelf is pulled out from this storage state, the movable rail 2 is moved by the guide roller 13 of the fixed rail 1 to the support piece 22, and by the guide piece 12 to the slide member 23.
are supported and pulled forward. Of the pair of protrusions 24 and 25, the front protrusion 24 is connected to the guide roller 13.
The operator can sense that the slide shelf is at the predetermined pull-out position due to the sense of moderation that occurs when crossing over the slider, and therefore finishes the pull-out operation. As a result, a pair of convex portions 24.2
5 stops on the slide shelf with the guide roller 13 sandwiched between the front and rear, and the slide shelf is in a state where movement in both the front and rear directions is restricted. This allows the sliding shelf to be temporarily fixed in a predetermined drawn-out state (see the state shown by the solid line in FIG. 1).

Therefore, as shown in Fig. 6, it is possible to operate the keyboard placed on the sliding shelf A while the sliding shelf A is reliably restricted from moving back and forth, thereby ensuring reliable key operations. I can do it.

Then, because the operator pulled it out forcefully, a pair of protrusions 24
．． 25 have gotten over the guide roller 13, the front end surface of the slide member 23 comes into contact with the front stopper member 14 immediately after the rear convex part 25 gets over the guide roller 13, and the final state is reached. Further forward movement is restricted (see the three-dot chain line in Figure 1). As a result, even if a pulling force of A-1 is applied to the sliding shelf, the movable rail 2 will not separate from the fixed rail 1, and this sliding shelf can be reliably prevented from falling when pulled out. can be reliably supported.

Furthermore, when it becomes necessary to completely pull out the slide shelf, the front stopper member 14 can be removed. Thereby, the slide member 23 can be pulled out further forward from the above-mentioned final state, and the slide shelf can be pulled out from the shelf body.

Also in this example. A ready-made screw with a screw head of a predetermined size is used as the stopper member 14, 15, and there is no need to process a special member, so it can be manufactured at low cost, and its installation can be done by simply screwing it in. Because there is, it can be done easily.

Note that other aspects of the above embodiment will be described below.

A. The stopper member is not limited to a screw, and any material that can be easily released may be used.

B. The slide member may be composed of a pair of upper and lower rollers, for example.

The C3 rear stopper member may be integrally formed by, for example, bending the rear end of the guide piece 12 of the fixed rail 1 in the vertical direction.

D. The mounting position of the front stopper member 14 may be set so that the pair of convex portions 24 and 25 sandwich the guide roller 13 from the front and back and contact the slide member 23 at the same time.

〔Effect of the invention〕

According to the slide shelf support device of 1 Shimizu item 1 of the present invention, when the slide shelf is in the drawn-out state, the pair of convex portions of the moving rail sandwich the guide roller from the front and back, so that the slide shelf can move in both the front and rear directions. The movement of the drawer is restricted and the drawer can be temporarily fixed in a predetermined drawn state. Moreover, even if a pulling force is further applied to the slide shelf from this state, the slide member and the stopper member come into contact with each other and further movement of the slide shelf is restricted, so that the slide shelf will not be pulled out. This can be reliably prevented. Therefore, it is possible to both temporarily fix the position of the sliding shelf in the drawn-out state and prevent it from falling when the sliding shelf is pulled out, and it is possible to reliably operate keys on a keyboard or the like placed on the sliding shelf.

In addition, since the stopper member is removable, it is easy to assemble the slide shelf to the fixed rail, and when necessary, the slide shelf can be completely pulled out, making maintenance easy. can.

According to the second aspect of the present invention, in addition to the effects of the first aspect, since the stopper member is formed of a screw, it is possible to easily and reliably attach and detach the stopper member.
