Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a ceiling, a duct, a water pipe, a gas pipe, embedded in concrete such as a building,
When installing other equipment, etc. on the ceiling with hanging bolts or fixing the foundation etc. with anchor bolts,
The present invention relates to a simple fastener that can attach a hanging bolt, an anchor bolt, or a hanger with one touch.

[0002]

2. Description of the Related Art Conventionally, in a ceiling of a building or the like, a nut member 101 as a fastener is embedded in concrete 100 which constitutes the floor of an upper floor, as shown in FIG. When the screw 102 is screwed in, a hanger 104 that supports a frame 103 to which a ceiling or the like is attached is attached to the lower end of the hanging bolt 102 with the nut
It is hung by fixing with 05.

[0003]

However, in the conventional fastener, one suspension bolt 102 is attached,
Since it has to be screwed in one and there are many places to hang it, the number of man-hours required for mounting is enormous.

Further, the floor surface of the upper floor is not always flat. In this case, in the conventional fastener, in order to adjust the height of the ceiling or the like, the nut 105 is turned to move the hanger 104 up and down to adjust the height of the ceiling or the like, but the adjustment method is troublesome. Since the number of places to hang is so large, the number of installation steps has become enormous.

The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to provide a simple fastener capable of one-touch attachment of a bolt (or attachment to a bolt) and height adjustment of a ceiling or the like. .

[0006]

In order to achieve the above-mentioned object, the present invention has a casing member into which a shaft member is movably inserted, and a shaft member into which a shaft member is movably inserted through a through hole. And a lock plate whose one end is linked to the casing member and whose other end is attached so as to be tiltable in the vertical direction and which locks the relative movement of the shaft member by raising the edge of the through hole with respect to the shaft member due to tilting. It is characterized by becoming.

The lock plate can be attached while being biased by a spring member. The shaft member may be composed of a full screw bolt, and a plurality of lock plates can be used.

The spring member is mounted between the lock plate and the casing member to urge the lock plate in one direction, or is mounted between the lock plates.
The lower lock plates may be biased to tilt in opposite directions.

Further, the lock plate may be attached to the casing member in a linked manner via a lock block having one end made of an elastic member.

A portion of the casing member embedded in concrete has a closed structure, and a protrusion for preventing the concrete member from coming off can be formed outside the closed structure.

Further, the shaft member through hole of the casing member is formed in a cylindrical portion projecting outward, and a pressing plate is externally inserted into the cylindrical portion, and the pressing plate is connected between the casing member and the pressing plate. It may be supported by a compression spring mounted between them and a spring that expands and contracts in the radial direction mounted between the tip of the tubular portion and the pressing plate.

Further, the outer shape of the casing member can be formed into a non-circular shape which can be rotated by a jig or the like.

[0013]

Since the present invention has the above-described structure, the relative movement of the shaft member and the casing member is locked by the rising of the edge of the through hole with respect to the shaft member due to the tilting of the lock plate, and the lock plate is the spring member. When the shaft member is rotated against a force to be orthogonal to the shaft member, the lock is released and the shaft member and the casing member can be moved relative to each other.

The mutual movement is locked only in one direction when one lock plate is used, and its locking force can be increased by increasing the number of lock plates used. Also, when two lock plates are used above and below the spring member, the lock plates tilt in opposite directions to provide a two-way lock (upward and downward).

When the lock plate has one end linked to the casing member through the lock block, vibration is absorbed by the lock block and generation of abnormal noise is prevented.

By making the portion to be embedded in concrete a closed structure, concrete can be prevented from flowing into the interior to ensure a reliable operation, and the protrusions formed on the outside can prevent the concrete from coming off to stabilize the installation. Can be planned.

Further, the shaft member through hole is formed in the tubular portion, and the pressing plate is attached to the tubular portion by a compression spring and a spring expanding and contracting in the radial direction, whereby the tubular portion is formed. The fastener itself can be attached to the attached member by inserting it into the attached hole.

Further, the fastener can be used as a nut by making the outer shape of the casing member non-circular.

The lock plate 12 is formed of a rectangular plate-like member, and a through hole 12a through which the shaft 14 is inserted is formed at a substantially central portion of the plate-like member. The through hole 12a at this time is formed to be slightly larger than the outer diameter of the shaft member 14. The lock plate 12 is attached by engaging the one end portion 12b with the square hole 11e, and after the attachment, the other end portion 12c can be vertically tilted about the one end portion 12b.

The spring member 13 is composed of a compression coil spring wound to have a diameter larger than the outer diameter of the shaft member 14, and is mounted between the lock plate 12 and the lower piece of the casing portion 11b so that the lock plate 12 can be secured. It is biased to tilt upward.

Here, the shaft member 14 is formed of all-screw bolts, and the base end portion is fixed to the ceiling and the tip end portion is attached so as to hang down. The fastener A is attached to the shaft member 14 as follows.

The through hole 11c formed in the upper piece of the casing 11b is opposed to the tip of the shaft member 14 to move the fastener A upward (direction c). As a result, the tip of the shaft member 14 enters the casing 11b, and the tip of the shaft member 14 rotates the lock plate 12 in the a direction. By this rotation, the tip of the shaft member 14 is locked by the lock plate 1.
The second through hole 12a can be inserted into the through hole 12a, and the lock plate 12 and the spring member 13 can be penetrated through the through hole 11d formed in the lower piece of the casing portion 11b to project downward. When the upward external force applied to the fastener A is released in this state, the lock plate 12 is tilted upward by the spring member 13 (direction b), and the edge of the through hole 12a of the lock plate 12 with respect to the shaft member 14 is removed. By raising the part, the downward movement (direction d) of the fastener A is locked.
In this way, the fastener A moves upward with respect to the shaft member 14, but the downward movement is locked. To release this lock, the lock plate 12 is rotated in the a direction against the spring force of the spring member 13 and the edge of the through hole 12a with respect to the shaft member 14 is released to release the fastener A in the d direction. It is possible to move (lower).
