Description

The present invention relates to a support device for a slide shelf on which a keyboard of, for example, an OA device (word processor, computer, etc.) is placed.

[Conventional technology]

For example, as a shelf on which a keyboard of a word processor is placed, as shown in FIG.
A shelf B in which is incorporated is known.

In this shelf B, the word processor main body W is placed on the upper surface, and the keyboard K is placed on the slide shelf A,
Keyboard K by pulling slide shelf A forward
When the slide shelf A is pushed in, the keyboard K can be stored.

Conventionally, as a support device for the slide shelf A for the keyboard, generally, a device that slidably supports the slide shelf by a guide rail is known.

[Problems to be Solved by the Invention]

In the above-mentioned conventional supporting device, generally, there is provided retaining means for preventing the slide shelf A from falling out from the pulled-out state to the front, but means for restricting the movement in the pushing direction (rearward) from the pulled-out state. Is not provided.

Therefore, when a backward force is applied to the slide shelf A during the operation of the keyboard K, the slide shelf A slides backward, which causes a malfunction of the keyboard K.

Therefore, the present invention provides a support device for a slide shelf which has both functions of fixing a temporary position when the slide shelf is pulled out and preventing the slide shelf from being pulled out, and which allows easy attachment and detachment of the slide shelf.

[Means for solving the problem]

The invention according to claim 1 comprises a moving rail attached to both sides of the slide shelf, and a fixed rail attached to a support in which the slide shelf is incorporated to guide the movement of the moving rail. A guide roller is rotatably attached to the front end around a horizontal axis, and a guide edge portion is provided so as to project toward the moving rail side. A stopper member is detachably attached to the guide edge portion and is attached to the moving rail. Is a slide member that blocks the forward movement of the slide rack by abutting the stopper member from the rear side when a forward pulling force acts in a state where the slide rack is pulled out to a use position where it projects forward. Is provided, and a supporting edge portion supported from below by the guide roller is provided so as to project toward the fixed rail, and
The support edge portion is provided with a pair of convex portions that sandwich the guide roller from both front and rear sides in a state where the slide shelf is pulled out to the use position.

According to a second aspect of the present invention, in the structure of the first aspect, a screw is screwed into the guide edge portion of the fixed rail as the stopper member.

[Action]

According to the above configuration, in the state where the slide shelf is pulled out to the use position, the pair of convex portions of the moving rail sandwiches the guide roller from the front and the back to temporarily fix the slide shelf to the use position and prevent an unexpected rearward movement. It can be prevented (temporary position fixing function).

On the other hand, when the pulling force is further applied to the slide shelf from the use position, the slide member comes into contact with the stopper member and the forward movement of the slide shelf is blocked (removal preventing function).

Moreover, since the stopper member is detachable, by removing the stopper member when assembling the movable rail to the fixed rail and when pulling out the slide shelf,
It is possible to easily assemble and disassemble the moving rail with respect to the fixed rail, that is, to attach and detach the slide shelf without any obstacle.

Further, according to the structure of claim 2, since the screw is used as the stopper member, the stopper member can be easily attached and detached.

〔Example〕

 An embodiment of the present invention will be described with reference to the drawings.

 Reference numeral 1 is a fixed rail, and 2 is a movable rail.

The fixed rail 1 includes a vertical strip-shaped mounting edge portion 11 and a strip-shaped guide edge portion 12 protruding inward from the mounting edge portion 11.
A guide roller 13 and a pair of stopper members 14 and 15.

The mounting edge portion 11 and the guide edge portion 12 are integrally formed by bending the strip material so that the cross-sectional shape thereof is substantially L-shaped except for the front end portion.

The guide roller 13 is attached to the inner surface of the front end portion 110 of the attachment edge portion 11 so as to be rotatable around a horizontal axis.

Further, a screw hole 112 through which the mounting screw 111 is inserted is formed through the mounting edge portion 11.

Headed screws are used for the stopper members 14 and 15, and screw holes 120 and 122 for attaching the stopper members 14 and 15 are formed at predetermined positions in the front and rear portions of the guide edge portion 12 so as to penetrate therethrough.

The moving rail 2 includes a mounting edge portion 21, a support edge portion 22 protruding outward from the mounting edge portion 21, a slide member 23 provided at a rear end portion of the mounting edge portion 21, and a pair of convex portions 24. , 25.

The mounting edge portion 21 and the support edge portion 22 are integrally formed by bending a strip material so that its cross-sectional shape is substantially L-shaped.

The slide member 23 is composed of a pair of slide pieces 231 and 232 facing each other vertically as shown in FIGS. 1 and 3.
The pair of slide variables 231 and 232 are provided so as to project outward from the mounting edge portion 21 so that the distance between them is slightly larger than the plate thickness of the guide edge portion 12 of the fixed rail 1.

The pair of convex portions 24, 25 guide the guide roller 13 when the slide shelf A is pulled out to the use position (the state shown by the solid line in FIG. 1).
The supporting edge portion 22 is formed so as to be sandwiched from the front and rear at a predetermined interval so as to project downward.

Further, a screw hole 212 through which the mounting screw 211 is inserted is formed through the mounting edge portion 21.

As shown in FIGS. 1 and 4, the movable rail 2 includes a guide edge portion 12 of the fixed rail 1 between a pair of slide pieces 231 and 232.
The lower surface of the support edge portion 22 is supported by the guide roller 13 of the fixed rail 1 in a state of sandwiching.

The slide member 23 is rearwardly moved to the front stopper member 14 in a state where the slide shelf A is pulled out further forward than the use position and the rear convex portion 25 has passed over the guide roller 13 (the position shown by the three-dot chain line in FIG. 1). From the side, the slide shelf A is prevented from moving forward (falling off).

Further, when the slide rack A is pushed in, the slide member 23 contacts the rear stopper 15 from the front side, whereby the slide rack A is stopped at the pushing position.

The front stopper member 14 is screwed into the guide edge portion 12 from below, and the length of the screw portion is set so that the screw end does not project from the upper surface of the guide edge portion 12.

In this slide shelf support device, the fixed rail 1 is previously screwed into the rear screw hole 122 of the rear stopper member 15 by means of a screw 111 and the rack main body B (see FIGS. 1 and 6).
(See the figure).

When assembling the slide rack A to which the movable rail 2 is attached to the fixed rail 1, first, the rear end of the slide rack A is inserted into the rack main body from above the guide roller 13 as shown in FIG. Insert the support edge 22 onto the upper surface of the guide roller 13 (see the solid line in the figure).

Next, when the slide shelf A is pushed in in this state, the moving rail 2 moves rearward while the lower surface of the supporting edge portion 22 thereof is supported by the guide roller 13, and the guide edge portion 12 is inserted between the pair of slide pieces 231 and 232. .

As a result, the slide shelf A is supported by the lower slide piece 232 and the guide roller 13 at two points (see the chain double-dashed line in the figure).

Thereafter, the front stopper member 14 is screwed into the front screw hole 121 from below, whereby the assembling of the slide shelf A to the shelf body B is completed.

In this support device, when the slide shelf A is pushed into the shelf body B, the slide member 23 is fixed rail 1
It contacts the rear stopper member 15 and is restricted from moving further rearward, whereby the slide shelf A stops at the pushed-in position (state shown by the chain double-dashed line in FIG. 1).

On the other hand, when the slide rack A is pulled out from this pushing position, the movable rail 2 is pulled out forward while the support edge portion 22 is supported by the guide roller 13 and the slide member 23 is supported by the guide edge portion 12.

Then, when the front convex portion 24 of the pair of convex portions 24 and 25 has passed over the guide roller 13, the slide shelf A reaches the use position. At this time, the user can clearly recognize the arrival at the use position by the feeling that the front convex portion 24 gets over the guide roller 13.

In this state, the pair of convex portions 24 and 25 sandwich the guide roller 13 from both front and rear sides, so that the slide shelf A is restricted from moving in the front and rear direction. That is, the slide shelf A is temporarily fixed to the use position.

On the other hand, at the time of this pulling out, when both convex portions 24 and 25 both surpass the guide roller 13 due to excessive force, the rear convex portion
Immediately after 25 has passed over the guide roller 13, the slide member 23 comes into contact with the front stopper member 14 to exert a stopper action.

This ensures that the slide shelf A is prevented from falling off.

When it is necessary to completely pull out the slide shelf A, the front stopper member 14 may be removed.

In this way, the slide member 23 can move freely forward without being obstructed by the stopper member 14, so that the slide shelf A can be easily pulled out.

Other Embodiments (1) The stopper members 14 and 15 may be other than screws as long as they can be easily attached and detached.

(2) The slide member 23 may be composed of, for example, a pair of upper and lower rollers.

(3) The rear stopper member 15 may be formed by bending the rear end of the guide edge portion 12 of the fixed rail 1, for example.

(4) The front stopper member 14 may be provided at a position where the slide member 23 abuts at the same time when the pair of convex portions 24 and 25 sandwich the guide roller 13 from the front and rear.

〔The invention's effect〕

As described above, according to the present invention, when the slide shelf is pulled out to the use position, the pair of protrusions provided on the moving rail sandwiches the guide rollers from the front and rear sides to temporarily move the slide shelf to the use position. Can be fixed.

Further, when a pulling force further forward from the use position acts on the slide rack, the slide member comes into contact with the stopper member, so that the slide rack can be reliably prevented from falling off.

That is, it is possible to exhibit both the temporary position fixing function of the slide shelf and the retaining function.

Moreover, since the stopper member is removable, by removing the stopper member when assembling the slide shelf to the fixed rail and pulling it out, that is, when attaching and detaching the slide shelf, these operations can be performed easily without any obstacle. It can be carried out.

Further, according to the invention of claim 2, since the screw is used as the stopper member, attachment / detachment of the stopper member, and consequently attachment / detachment of the slide shelf, become easier.
