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 an appliance such as a jump rear from a ceiling or the like.

[Technical background between axes]

As described in Japanese Utility Model Publication No. 57-5366, there has been known a fixture that allows fixtures to be attached to the ceiling simply by operating from below the ceiling. This fixture has an IH cross section; 5 inverted U-shaped elongated hooks allow the rotary support to rotate freely
Attach the bolt to the rotating support, screw the bolt into the rotating support, attach the hook to the bolt by rotating the tool vertically, and in this state, push the bolt and hook into the ceiling hole, and attach the hook to the ceiling. Rotate horizontally above the hole! IIJ-locks on the upper surface of the rim;
The bolt is suspended and the equipment is attached to the bolt.

However, if it is not possible to secure the hook to the top surface of the edge due to conditions such as the ceiling structure, the hook can be attached to the side of the edge using a hard fastener such as a wood screw. As a result, both sides of the hook may be deformed inward by the tightening of the fixing tool, and the bolt may come off the hook.

[Purpose of the invention]

The present invention was made in view of the above-mentioned drawbacks, and the hook is a device that can securely support a bolt without deforming both side surfaces when the both side surfaces of the tool are fixed with fasteners such as wood screws. It provides equipment.

[Summary of the invention]

The present invention provides an apparatus for supporting the bolt by attaching a hook to the bolt and inserting it through a construction surface, for example, a hole in the ceiling, and locking the hook to the upper surface of a field edge, etc.
The hook is a hook that increases the strength of both sides of the tool so that the tool can be attached to the side of a field edge, etc. with a tool such as a wood screw. The configuration consists of an upper surface and a pair of spaced-apart opposing Ifil1s hanging from both sides of the upper surface.
The elongated hook has a surface portion, a bolt, and the hook described in ii and l is rotatably attached to the tool and has a threaded groove for screwing the bolt therein. A tool is rotated vertically, attached to a bolt, and inserted into a hole made in a construction surface such as a ceiling. The engaging piece is formed by bending and forming engaging pieces that are butt-joined to each other on both side surfaces of the tool, and mounting portions for the fixing tool are formed on both side surfaces.

[Embodiments of the invention]

Next, the configuration of an embodiment of the present invention will be explained with reference to the drawings.

(1) is a hook, which has an upper surface and a pair of spaced-apart opposing side plates f2) (3) hanging down from both sides of the upper surface, and is formed, for example, in a generally inverted U-shape in cross section, and has both side surfaces (2) (
Both ends of the lower edge of 3) are formed into uneven locking edges (4).

Further, this hook is formed with a long hole-shaped bolt insertion portion on the upper surface of the tool (1), which is offset toward one end side from the center portion in the length direction of the tool (1).

Also, this hook is attached to both sides (2) of the tool (1).
is cut and bent inward, and this engagement piece (5)
A mounting portion (8) for a fastener (7) such as a wood screw is formed at the cut and raised portion (6).

Reference numeral (9) denotes a rotation support, which is formed in a substantially annular shape and whose inner circumferential surface is formed into a threaded structure Q2 into which a bolt OI is screwed.

The rotation support (9) has the hooks on both sides (2) of the tool (1). It is rotatably attached to the side using a rljll support pin 01).

The rotary support (1) is screwed into the thread groove α2 of the rotation support (9).

Next, the operation of this embodiment will be explained.

'When installing the hook by locking the tool (1) as shown in Fig. For example, ceiling α
If the lower end side of the hole (inserted into 131, hook f1) formed in J goes through the ceiling hole 0 (more upwards), the hook (1) will be biased towards one end of the rotation support (9) from the center. Since the hook (1) is pivoted on the bolt, it is rotated by a slight vibration in a horizontal direction perpendicular to the bolt (00).
When pulled downward, both end locking edges (4) of the hook (1) are locked to the upper surface of the hook (I). In this state, the upper end of bolt 0 (with hook) protrudes from the bolt insertion portion.

Then, when the bolt aω is rotated to adjust the length of the bolt (10) projecting downward from the ceiling α, the bolt Go) is moved upward by being screwed into the rotation support member (9). Next, the bolt is fastened to the support 00 that is in contact with the ceiling α by the force of the screwed nut α.

Next, if the hook can be used to lock the tool (1) on the top surface of the edge I, use the hook A (1) as shown in Figure A14 and Figure 5.
Assuming that the bolt (1) is in a horizontal plane perpendicular to the bolt (1), the hook is the same (1), and a fastening device such as a wood screw (force) is inserted into the claw side capital (8) of the bolt (14). Attach 11.

At this time, the hook is on the side of the line of the tool (7), and the side part (2) of the tool (1) is on the other side.
Although it is pressed toward kl'+(3), the engagement piece (5) (
6) are butt-jointed to each other so that they are not deformed. Even in this state, the upper end of the bolt (10) hangs down from the bolt insertion part, and the lower end of the bolt (a) projects downward from the ceiling hole 09.

Next, the configuration of another embodiment will be explained with reference to the drawings.

In the embodiment described above, the retaining pieces (5) (61) were cut and raised from the lower edges of the both side surfaces (2) and (3) of the tear-down gear (1). 2) From (3), hit 'f!
Engagement pieces (5) and (6) are formed using the punched pieces bent in different directions, and the die-cut holes of the engagement pieces (5) and (6) are used to secure the fasteners (
It is also possible to form an attachment part (8) through which the holder 7) is inserted.

In the structure of this embodiment, the strength of the hook (1) is further increased, and the bolt (10) is reliably prevented from coming off.
Even if an upward force is applied to the bolt θ, the bolt OI will not come off, so the puller 14' can also be installed in the opposite direction.

〔Effect of the invention〕

According to the present invention, the hook having a top surface and a pair of spaced and opposing side surfaces hanging down from both sides of the top surface is formed by bending engagement pieces that are butted and joined to both side surfaces of the tool, respectively, and is attached to both side surfaces of the tool. IAI *Since we have formed the mounting part for the fixture, it can be hooked into the hole in the construction surface such as the ceiling.
If A is attached to the bolt and inserted, and the hook cannot lock the tool inside the hole, the tool can be attached to the side of the field edge etc. with a fastener such as a wood screw. Furthermore, when tightening this fixture, both sides of the pull 1↓1 fixture will not be deformed by the retaining pieces that are engaged with each other, so the bolt will not come off and the fixture can be safely tightened. It can be hung and supported, and the tool itself is reinforced because the engaging pieces are butt-joined to each other, and the strength of the hook is increased even when the tool is held in place to add more copies.
