Description

[Detailed Description of the Invention] The present invention relates to a hanging device that is attached to a rail such as a curtain rail and used for hanging various exhibits.

A conventional hanging device of this type is disclosed in Japanese Utility Model Application Publication No. 162785/1985. This involves attaching a fixing member (head 6) to the upper end of the bolt body (hanging rod 2), attaching a hook (hanging ring 1) to the lower end, and installing a washer (washer 9) and nut 8 in the middle. More specifically, the hook (hanging ring 1) is rotatably attached to the bolt body (hanging rod 2). By rotating the hook at a predetermined angle with respect to the bolt body, the hanging tool having such a configuration can be applied to both a rail attached to a ceiling and a rail attached to a vertical wall. However, since the hook of such a conventional hanging device is attached to the end of the bolt body, a large moment is applied to the fixing member or the rail, especially when the hook is attached to a vertical wall. Furthermore, since the hook is attached to the end of the bolt body, a wide gap is formed between the wall surface and the hanging exhibit, which may cause the exhibit to wander. Further, in the conventional hanging device as described above, the hook cannot rotate about the axis of the bolt body.

The present invention was developed based on the above-mentioned circumstances, and its purpose is to prevent large moments from acting on the fixed member side, thereby providing high durability, and to be applicable to rails attached to vertical walls. Even at times, there is no gap between the wall and the hanging exhibits, so it is possible to display the exhibits accurately. It is an object of the present invention to provide a hanging tool that can be easily carried out.

In order to achieve the above object, the present invention is characterized by the following structure. That is, a bolt body, a fixing member attached to one end of the bolt body, a nut body screwed onto the bolt body, and a nut body that is externally fitted onto the bolt body between the nut body and the fixing member. a washer, an elastic member that biases the washer toward the fixing member and biases the fixing member toward the washer, and a gap is formed between the bottom surface of the washer and the upper edge of the nut body; a washer body that transmits the tightening force of the nut body to the washer; a hook mounting member that is partially interposed in a gap formed by the washer body and is rotatable around the bolt body; The hook is rotatably attached to the hook attachment member about an imaginary axis substantially orthogonal to the central axis of the hook.

Hereinafter, the present invention will be explained in detail based on embodiments shown in the drawings.

FIG. 1a is a side cross-sectional view showing the structure of the hanging tool of this embodiment, and is a diagram showing a state in which the hanging tool is applied to a rail attached to a ceiling. 2B is a front view of the same, FIG. 2A is a side view showing a state in which the hanging tool is applied to a rail attached to a vertical wall, and FIG. 2B is a front view of the same. In the figure, reference numeral 1 indicates a rail such as a curtain rail. This hanging tool is attached to such a rail 1 to perform its functions.

The configuration of the hanging tool will be explained. In the figure, reference numeral 2 indicates a bolt body. A fixing member 3 is attached to one end of the bolt body 2 (ie, the upper end in FIG. 1a). This fixing member 3 is shown in FIG.
As shown in b and c, the width 4 between both side edges is the same as the rail 1.
is formed smaller than the opening width 1a of the
The width 5 between both ends is larger than the opening width 1a of the rail 1. Due to this shape, the fixing member 3 can be easily inserted into the inside of the rail 1 through the opening by an insertion operation involving rotation of about 90 degrees. Also,
The bottom of the fixing member 3 has both ends 3 as shown in FIG. 3b.
a, 3a are formed to protrude from the middle part,
Therefore, the bottom end portions 3a, 3a can accurately contact the inner bottom surface of the rail 1. A nut body 6 is screwed into the bolt body 2. Also,
A washer 7 is fitted onto the bolt body 2 between the nut body 6 and the fixing member 3.

In the figure, reference numeral 8 is a washer body. This washer body 8 has a stepped cylindrical shape. This washer body 8 is externally fitted onto the bolt body 2 between the washer 7 and the nut body 6 with the large diameter cylindrical portion facing the nut body 6. By the way, the outer diameter of the large diameter cylindrical portion of this washer body 8 is larger than the inner diameter of the washer 7,
On the other hand, the outer diameter of the small diameter cylindrical portion is smaller than the inner diameter of the washer 7. Therefore, the washer 7 is fitted onto the small diameter cylindrical portion of the washer body 8 and abuts against the step portion 8a. In this state, the washer body 8 transmits the tightening force of the nut body 6 to the washer 7. Furthermore, even when the washer 7 is pressed against the rail 1 by tightening the nut body 6,
The washer body 8 is configured to form a gap 9 between the bottom surface of the washer 7 and the upper edge of the nut body 6.

In the figure, reference numeral 10 indicates an elastic member such as a coil spring. The elastic member 10 is housed within the large diameter cylindrical portion of the washer body 8 and is externally fitted onto the bolt body 2. The elastic member 10 urges the washer 7 in the direction of the fixing member 3 and
is biased in the washer 7 direction. As a result, washer 7
Even when the fixing member 3 is not tightened by the nut body 6, it is brought into contact with the rail 1 with an appropriate pressing force and its free movement is restricted to some extent.

In the figure, reference numeral 11 is a hook attachment member.
This hook mounting member 11 has a donut disk-shaped base 1.
Two arm parts 11b, 11b are formed by bending from the peripheral edge of 1a. The hook mounting member 11 is fitted onto the washer body 8 with a portion thereof interposed in the gap 9 formed by the washer body 8, and is therefore freely rotatable around the bolt body 2. It is becoming. Further, a hook 12 is rotatably attached to the arm portions 11b, 11b. Here, the rotation is the bolt body 2
It is centered on an imaginary axis 13 that is substantially orthogonal to the central axis of.

Next, the effects of the hanging tool having the above-described configuration will be explained.

If rail 1 is attached to the ceiling,
Hang the exhibit in the state shown in Figures 1a and b. That is, the fixing member 3 is inserted into the inside from the opening of the rail 1.
and place both ends 3a, 3a on the inner bottom surface of the rail 1, and then turn the nut body 6 to remove the washer 7.
When the fixing member 3 is pressed against the rail, the state shown in the figure is obtained. In this state, the hook 12 is rotatable around the bolt body 2 and the virtual axis 13, so
It is possible to accurately engage the metal fittings attached to the exhibit, and the work can be easily performed. Furthermore, when considering the display position, the nut body 6 may be loosened to allow the hanging tool to move along the rail 1. Even in this state, the washer 7 and the fixing member 3 are brought into contact with the rail 1 with an appropriate pressing force by the elastic member 10.
The hanging equipment will not move against your will.

If rail 1 is attached to a vertical wall,
Hang the exhibit in the state shown in Figures 2a and b. That is, the washer 7 and the fixing member (3) are in pressure contact with the rail 1 as in the case of FIGS. It is in a state where it is suspended at a substantially right angle to the other hand. Even in such a state, the above-mentioned FIG.
As in case b, the hook 12 can be accurately hooked to the metal fittings attached to the exhibit, and the work can be done easily. Furthermore, when considering the display position, the same effect as in the case of FIGS. 1a and 1b can be obtained. Further, the hook mounting bracket 11 is externally fitted onto the washer body 8 and eventually the bolt body 2 at a position close to the fixing member 3 and the rail 1.
is attached, so the fixing member 3 and rail 1
A large moment does not act on it, and therefore it has high durability. Further, for the same reason, the width 20 between the vertical wall and the hook 12 is shorter than in the conventional example, so that exhibits can be displayed accurately without hanging around.

Note that the present invention is not limited to the above-mentioned embodiment. For example, the washer and washer body may be integrally formed.

As is clear from the above explanation, according to the present invention, a large moment does not act on the fixed member side, and therefore it has high durability and also when applied to a rail attached to a vertical wall. A wide gap is not formed between the hanger and the hung exhibit, so it is possible to display accurately, and the hook can be rotated around the bolt body, making it easy to display. It is possible to provide a hanging tool that does the following.
