[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a device for suspending, for example, paintings, various kinds of exhibits, and other things on rails provided horizontally on a wall surface.

[0002]

2. Description of the Related Art Conventionally, there are two types of suspension devices for a rail. First, the suspending device is attached to the rail in advance before the rail is horizontally installed on the wall surface. This has been used for a long time, and its structure is that a rear plate for locking or a movable roller is provided at the rear part of a hook body for hanging a hanging tool such as a hanging rod or a hanging string. Yes, insert a stopper etc. in the rail before installing it horizontally on the wall,
In this state, the rail is installed horizontally on the wall surface.

Secondly, after the rail is installed horizontally on the wall surface, the suspending device can be fitted into the rail and attached. An example thereof is disclosed in Japanese Utility Model Laid-Open No. 63-25077. This is a rear plate for locking, the vertical width of which is larger than the vertical width of the front opening in the longitudinal direction of the rail and the horizontal width of which is smaller than the vertical width of the front opening, and the rear plate for locking is screwed from the front side. An operating knob body having a male screw portion, and a holding ring body that is movable in the axial direction between the locking rear plate and the operating knob body and is urged by a spring toward the locking rear plate side. Have
A hook portion is formed on the holding ring body.

To mount the rail, after the rail is installed horizontally on the wall surface, the rear plate for locking is put sideways into the rail with the front knob being loosened, and the rail is rotated 90 degrees to lock it. Hold the plate vertically and prevent it from slipping out with its vertical width larger than the vertical width of the front opening of the rail, then tighten the knob body and increase the biasing force of the coil spring to engage the side edge of the front opening of the rail with the holding ring. It is clamped and fixed between the rear plate for stopping.

A second type is described in Japanese Utility Model Laid-Open No. 3-67179 previously proposed by the applicant of the present invention in addition to the above. This consists of a substrate having a guide convex portion on the rear surface whose thickness is equal to the thickness of both sides of the front opening of the rail, a short shaft pivotally supported on the substrate and provided with a hanging rod downward, and a vertical width. Is slightly smaller than the vertical width of the front opening of the rail, the horizontal width is longer than the vertical width of the front opening, and has a rear plate for locking fixed to the rear end of the short shaft. It is fixed to the short shaft so that the rear plate for locking is inclined when it is vertical.

In this mounting, after the rail is installed horizontally on the wall surface, the locking rear plate is placed sideways and fitted into the rail from the front opening, and the guide convex portion of the board is engaged with the front opening of the rail. After that, the short shaft is rotated and the rear plate for locking is inclined so that the rail is locked at the inner edge of the front opening of the rail so as not to come out.

[0007]

However, in the first suspension device, the rear plate or the roller for locking has to be fitted in the rail before being mounted on the wall surface in advance, so that the rail is laterally mounted on the wall surface. After installation, the mounting device cannot be mounted. Therefore, the installation work of this suspension device is time-consuming as well as time-consuming.

The second one can be mounted after the rail is installed horizontally on the wall surface. However, the actual exploitation 63-2507
In the case of the device described in Japanese Patent Publication No. 7-74, the operation knob body had to be loosened once and then re-tightened at the time of installation, which required time and effort for the installation work.

Similarly, in the second one disclosed in Japanese Utility Model Laid-Open No. 3-67179, at the time of mounting, the suspension rod is slanted and the rear plate for locking is laterally fitted into the rail, and then suspended. body the rather good only the plate after the locking to the inclined shape in the vertical form, which facilitated the hanging and removal work
Is. Re only Chico, since the thickness of the guide projections of the substrate after the surface are equal to the thickness of the front opening side edges of the rail, the hanging device on the rail even after mounting once enabled sideslip There is. Les Therefore, for example, painting, etc.
If you want to hang by no lateral displacement at a specific location on Lumpur, it was that can not be used, a problem that point.

The present invention is intended to solve the problems of the above-described conventional suspension device for a rail. That is, the object of the present invention is to enable the rail to be installed after being installed horizontally on the wall surface, but also to simplify the operation of installing on the rail to improve workability, and to allow careless skidding once installed on the rail. It is an object of the present invention to provide a suspension device for a rail that does not move and can be easily moved laterally on the rail or removed if necessary.

[0016]

The above-described hanging device of the present invention is attached to the rail 1 horizontally installed on the wall surface 17 in advance as follows. First, the hook portion 9 of the suspending device of the present invention is photographed and rotated about the short shaft 3 to make the hook member 4 inclined. When the hook member 4 is inclined, the locking rear plate 5 fitted to the rear portion of the short shaft 3 has its longitudinal direction aligned with the longitudinal direction of the guide projection 7 of the substrate 2.

The locking rear plate 5 and the guide convex portion 7 at the rear portion of the base plate 2 whose longitudinal directions coincide with each other are aligned with the front opening 8 of the horizontal rail 1 provided on the wall surface 17. with this,
The vertical width a, which is slightly shorter than the vertical width b of the front opening 8 of the rail 1,
The guide protrusion 7 of f and the rear plate 5 for engagement are engaged in the front opening 8 of the rail 1. At this time, the rear plate 5 for locking is the substrate 2
Since the thickness d of the guide protrusion 7 is smaller than the thickness e of the side edge portion 11 of the front opening 8 while being pressed to the side by the spring member 6, the locking rear plate 5 is completely inward of the rail 1. It cannot enter and is in a state in which the surface 12 of the base side is engaged in the front opening 8.

Next, the hook member 9 is rotated about the short shaft 3 so that the hook member 9 is changed from the inclined shape when engaged with the front opening 8 of the rail 1 to the vertical shape. As a result, the locking rear plate 5, which is locked and fitted on the short shaft 3 in the rotational direction, is rotated obliquely from the state in which it coincides with the front opening 8 of the rail 1. . Since the peripheral portion 13 of the board-side surface 12 is curved toward the side opposite to the board 2, the rear plate 5 for locking at the time of this rotation does not get caught on the side edge portion 11 of the front opening 8, and The spring member 4 is contacted with the side edge portion 11 of the front opening 8 by the cam action to itself.
It rotates while retracting against the pressing force of, and gradually enters from the peripheral portion 13 into the inside of the side edge portion 11 of the front opening 8 of the rail 1.

Further, as the locking rear plate 5 rotates, the center portion without the curved surface also enters the inside of the side edge portion 11, and the locking rear plate 5 prevents the spring member 6 from slipping. When the hook member 4 is rotated to the vertical state while being pressed against the inner side surface 15 of the side edge portion 11 due to the pressing force of
It is inclined inside the rail 1 (see FIG. 3). In this way, the rear plate 5 for locking enters the inside of the rail 1 and is inclined.
State and receives the pressing force of the spring member 6, the is pressure contact with the inner surface 15 of the side edges 11 of the front opening 8. This is the book suspension device
Mounted on rail 1 and once mounted
After that, it does not move carelessly on the rail 1 in the lateral direction (see FIG. 1).

In order to remove the main suspension device once attached to the rail 1, the vertical hook member 4 is rotated to be inclined when attached. As a result, the rear plate 5 for locking, which is inclined inside the rail 1 and pressed against the inner side surface 15, becomes the same horizontal direction as the front opening 8 of the rail 1 in the longitudinal direction, and can be pulled out as it is. The suspension device can be removed from the rail 1.

Also, when the main suspension device once attached to the rail 1 is moved in the lateral direction, the vertical hook member 4 is rotated to be inclined when attached. Thus, similarly to the above, the rear plate 5 for locking, which is inclined inside the rail 1 and press-contacts the inner side surface 15, opens the front surface of the rail 1.
It becomes the same horizontal shape as the mouth 8, and the pressed state is released . There
Then, the guide protrusion 7 on the rear surface of the substrate 2 is connected to the front opening 8 of the rail 1.
While engaged in it may be moved laterally. After Les
When the hook member 4 is vertically rotated at a desired position on the roll 1, the rear plate 5 for locking becomes inclined again inside the rail 1 and the spring member 6 for preventing slippage is used. Pressure on the inner surface 15
Prevents accidental skidding by being contacted and locked .

EFFECT OF THE INVENTION The suspension device for a rail according to the present invention can be installed after the rail is laid horizontally on the wall surface, and the work for mounting on the rail is easy and the workability can be improved. After being installed once, there is no accidental skidding, and if necessary, removal and lateral movement on the rail can be performed easily and quickly.

That is, in the conventional suspension device of this type,
Even if the rail cannot be installed after it is installed horizontally on the wall and installation work takes time and time, or even if the rail can be installed after it is installed horizontally on the wall, it can be troublesome to loosen or tighten the operation knob during installation. Such a device, or a device that can be easily mounted, slides on a rail after mounting.

On the other hand, in the suspension device for the rail according to the present invention, the rail is installed horizontally on the wall surface, and then the rear oblong locking rear plate is engaged in the front opening of the rail. Then, it suffices to rotate the hook member vertically.

The rear plate for locking engaged in the front opening of the rail is rotated by the hook member, and the peripheral portion of the substrate side surface of the rear plate for locking is curved toward the side opposite to the substrate. Because
The rear plate for locking can be rotated without the peripheral portion being caught on the side edge of the rail front opening. With this, the rear plate for locking enters the inside of the rail and becomes inclined inside, so that the main suspension device can be attached.

Further, when the locking rear plate engaged with the front opening of the rail by the hook member is rotated, the thickness of the guide convex portion at the rear portion of the board is smaller than the thickness of the side edge portion of the front opening of the rail. Since it is slightly thin, the rear plate for locking, which receives the pressing force of the spring member for slip prevention , presses the inner surface of the side edge of the front opening inside the rail. As a result, the rear plate for locking and the rail are brought into a locked state, and the main suspension device is locked at a specific position, so that careless lateral movement can be eliminated. for that reason,
For example, make sure that paintings, etc. do not shift laterally at a specific position on the rail.
It can also be used if you want to hang it .
