Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an appliance mounting device, and more particularly, to an apparatus for suspending and supporting appliances such as a chandelier from a ceiling or the like.

[Technical background of the invention and its problems]

Conventionally, when attaching heavy equipment to ceilings, etc., the tightening force of wood screws was insufficient, so
An instrument mount having a structure as described in Japanese Patent No. 5363 is known. This equipment attachment is made by screwing a bolt onto a rotating support that is rotatably attached to a long and narrow hook, and inserting the hook into a vertical position attached to the bolt. The hooks are fixed to the top of the veranda, and the fixtures are suspended and supported from bolts hanging from the ceiling.
However, with this structure, when the hanging tool is rotated vertically and attached to the bolt and inserted into the ceiling hole, the hanging tool cannot be rotated horizontally unless a strong impact is applied to the hanging bolt. , I was unable to attach the hook to the edge of the field.

For this reason, the mounting described in Japanese Utility Model Publication No. 57-5363 describes a structure in which the rotating support is pivoted at a position offset from the center of the hook, but even with this structure, the hook has a cross-section omitted. It is formed in a U-shape, and when the hook is made vertical, it ends up cradling the bolt, and has the disadvantage that the hook cannot be rotated horizontally unless a strong impact is applied.

Furthermore, in Japanese Utility Model Publication No. 57-5363, a coil spring is stretched between the hook and the rotating support, and the spring force of this coil spring causes the hook to rotate in the horizontal direction. Although a structure has been described, this structure requires a coil spring, takes time to assemble, has a large number of parts, and is expensive.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned drawbacks, and the present invention is designed so that when the hook is attached to the bolt, the hook can easily rotate in the horizontal direction to reach the locked state, and a hole provided in the construction surface, for example, the ceiling, is provided. To provide an instrument attachment device in which a hook is immediately rotated by a small impact when inserted into a device.

[Summary of the invention]

The present invention includes an elongated hook, a bolt, and a rotating support that is rotatably attached to the hook and has a threaded groove into which the bolt is screwed, and the hook is vertically mounted. In a device that rotates and attaches to a bolt and inserts it into a hole made in a construction surface such as a ceiling, the hook is rotated in a horizontal direction orthogonal to the bolt and locked, and the hook is attached to the bolt in a horizontal direction. When the hook is attached to the bolt for easy rotation, an engaging part is formed that abuts the middle part of the bolt and keeps the hook in an inclined state. The center of the hook is placed in an unstable position so that it is immediately rotated horizontally when inserted into the hook.

[Embodiments of the invention]

The configuration of an embodiment of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a hook having a substantially inverted U-shape in cross section, and both lower edges of both side surfaces 2 and 3 are formed with uneven locking edges 4.

Further, in the center of the upper surface of this hook 1, a long hole-shaped bolt insertion portion 6 is formed. Furthermore, an engaging portion 7 is cut and raised at one end of the upper surface of the hook 1 and projects inward.

Further, reference numeral 8 denotes a rotation support, which is formed in a substantially annular shape and has a threaded groove 10 on its circumferential surface into which a bolt 9 is screwed. The rotation support 8 is the hook 1.
The bolt insertion part 6 is rotatably attached by a pivot pin 11 to one end side of the bolt insertion part 6, which is offset from the longitudinal center of the hook 1 between the both sides 2 and 3 of the hook.

The bolt 9 is attached to the thread groove 1 of the rotation support 8.
It is screwed to 0.

Next, the operation of this embodiment will be explained.

As shown in FIG. 4, when the hook 1 is tilted vertically and attached to the bolt 9, the engaging part 7 comes into contact with the middle part of the bolt 9, and the hook 1 is rotated horizontally. In this state, it is inserted into a hole 14 formed in a construction surface, for example, a ceiling 13, and
When the lower end of the hook 1 comes out above the ceiling hole 14, the center of gravity of the hook 1 is in an unstable position because it is attached to the bolt 9 in an inclined manner, and the hook 1 is in a horizontal position. When the hook 1 is rotated and the bolt 9 is pulled downward, the locking edges 4 at both ends of the hook 1 are locked to the upper surface of the field edge 15. At this time, the upper end of the bolt 9 protrudes from the bolt insertion portion 6 of the hook 1.
In this state, the bolt 9 protrudes downward from the ceiling 13.
When the bolt 9 is rotated to adjust the length, the bolt 9 is moved upward by being threaded into the rotation support 8. After adjusting the protruding length of the bolt 9, the bolt 9
It is fixed with a nut 17 that is tightened and screwed into.

In the above embodiment, the bolt insertion part 6 of the hook 1 was formed in the shape of a long hole on the top surface 18, but one side surface 2
A recessed portion formed by curving toward the other side surface 3 may be used as a bolt insertion portion.

〔Effect of the invention〕

According to the present invention, the hook is formed with an engaging portion that comes into contact with the middle part of the bolt when the hook is attached to the bolt and maintains an inclined state that makes it easy to rotate the hook in the horizontal direction. Therefore, when the hook is attached to the bolt in order to insert it into a hole in the ceiling, the engaging part of the hook comes into contact with the middle part of the bolt.
The hook is held in an inclined position with its center of gravity at an unstable position, and the hook is immediately rotated horizontally after being inserted through a hole in a structure such as the ceiling, and the hook is placed on the top surface of the field edge. The bolt can be easily and quickly suspended and supported, there is no need to increase the number of parts, it is easy to assemble and can be obtained at low cost, and it is possible to suspend and support various heavy instruments.
