Description

[Detailed description of the invention] This invention is designed to suspend a suspended object placed horizontally in a ceiling opening, such as a ceiling inspection opening, from a horizontal member suspended above the opening. This invention relates to a hanging support device that can be assembled, and its purpose is to provide a hanging support device for ceiling inspection openings, etc. that can strengthen the installation state to the horizontal member and can be easily assembled to the horizontal member.

Next, an embodiment of the present invention will be described with reference to the drawings. In the drawing, 1 is a suspended object fitted in an opening 2 of a ceiling T so as to be openable and closable, and An inner frame 1a arranged in parallel inside and outside, and an outer frame 1b connected to this inner frame 1a by a rotation shaft 1c etc.
horizontally placed through.

Reference numeral 3 denotes a horizontal member horizontally suspended above the opening K, and has a U-shaped vertical cross section.

Next, explaining the suspension device C, 4 is orthogonal to the horizontal member 3 in order to suspend the suspended object 1 via a mounting piece 5 fixed to the outer frame 1b of the suspended object 1. It is a suspension rod attached to a suspension rod, and an engaging portion 4a for removably engaging and supporting the mounting piece 5 is formed in a curved manner at its lower end, while its longitudinal portion is formed in a vertical portion. An uneven portion 4b is formed with protrusions 6 to 6 arranged in parallel along the direction, and in this example, the uneven portion 4b is formed in the shape of a threaded rod.

Reference numeral 7 denotes support fittings which are elastically deformable by bending a strip material into a substantially C-shape in order to horizontally hold the horizontal member 3, and are vertically opposed to each other via folded portions 7a. The upper and lower pieces 7b, 7b are provided with upper and lower insertion holes 8, 8, which are opened in order to vertically penetrate the suspension rod 4 into the support metal fitting 7, and the upper and lower pieces 7b have a support metal fitting at the tip thereof. Knobs 9, 9 extended for expanding the upper and lower pieces 7b are bent, and edges 3a, 3a of the horizontal member 3 are provided near the proximal ends of both the tabs 9 of the upper and lower pieces 7b. Hang and support bracket 7
Bent upper and lower latching claws 10, 10 are provided opposite each other in order to releasably engage the horizontal member 3 with respect to the horizontal member 3.

Numerals 11 and 11 are recessed notches formed in the outer side edges 8a of both insertion holes 8, and 12 to 12 are threadedly engaged with the uneven portions 4b of the suspension rod 4 to lock the protrusion 6, and Rod 4
These are locking parts formed oppositely to the tip edges of the double concave notches 11 in order to releasably engage the suspension rod 4 or the support fitting 7. The locking position of the suspension rod 4 relative to the support fitting 7 can be adjusted up and down by turning the screw.

13 is a screw screwed into the folded portion 7a of the support fitting 7 so as to be able to come into contact with the suspension rod 4 in order to press the suspension rod 4 and the support fitting 7 in opposite directions;
When this screw 13 is screwed in, the suspension rod 4 is pressed against the side surface of the horizontal frame member 3, and the support metal fitting 7 is pulled back in the direction opposite to the screwing direction and tightened, so that it faces the horizontal frame member 3. The latching state of the latching claw 10 and the hanging rod 4
The locked state of the locking portion 12 with respect to the protrusion 6 is respectively locked.

Next, the operation and effects of the embodiment having the above configuration will be explained.

Now, in this example, upper and lower insertion holes 8 are provided in the support fitting 7, which is curved into a substantially C-shape in order to horizontally hold the horizontal member 3, and are provided with upper and lower insertion holes 8 for inserting the suspension rods 4 therethrough. are installed opposite each other, and the edges of the horizontal frame member 3 are hooked near both ends of the open side of the support metal fitting 7, so that the support metal fitting 7 is attached to the horizontal frame member 3.
Both latching claws 10 are formed for removably engaging with the suspension rod 4, and a protrusion 6 protruding from the suspension rod 4 is engaged with the outer edge 8a of both insertion holes 8. Both locking portions 12 are formed for locking the rod 4 to the support metal fitting 7 so that it can be locked and disengaged and its vertical movement can be adjusted.

For this reason, when assembling the suspension device C to the horizontal member 3, the suspension rod 4 is inserted through and engaged with the support fitting 7, while the support member 7 is elastically expanded and engaged with the horizontal member 3. Therefore, the suspension device C can be easily attached to the horizontal frame member 3, and when the support metal fitting 7 is tightened by screwing the screw 13, the support metal fitting 7 attaches to the horizontal frame member 3 through both latching claws 10. The hanging rod 4 can be firmly gripped and firmly locked through both the locking parts 12, and the assembled state of the hanging support device C to the horizontal member 3 is strengthened.
This has the effect of stabilizing the suspended state of the suspended object 1.

Next, a second embodiment of the present invention will be described with reference to FIG. 4. In this embodiment, the upper and lower insertion openings 8A of the support fitting 7A, which is formed to be elastically deformable with a spring material, extend through the suspension rod 4A in the lateral direction. It communicates with the outside through insertion parts 14, 14 which are separated for insertion into the upper and lower insertion holes 8A, and the screws 13 of the first embodiment have been removed.

Then, the support fitting 7A elastically holds the horizontal member 3A via both the latching claws 10A, and both the insertion holes 8A
The suspension rod 4A inserted therein is configured to be elastically locked by the upper and lower locking portions 12A.

The functions and effects of the second embodiment are explained in the first embodiment.
Since it is almost the same as the embodiment, its explanation will be omitted.

In other words, the present invention has a support metal fitting that is curved to horizontally hold a horizontal member suspended above an opening in the ceiling, and a suspension support that is vertically installed to suspend an object to be suspended. Upper and lower insertion holes for inserting the rods are provided opposite each other, and edges of the horizontal member are hooked near both ends of the open side of the support metal fitting to allow the support metal fitting to be inserted into the horizontal frame. A pair of locking claws are respectively formed to releasably engage the material, and further,
Projections arranged in parallel along the longitudinal direction of the suspension rod are hooked to the edge of the insertion opening, so that the suspension rod is engaged with and detachable from the support fitting and can be adjusted to move up and down. By forming a locking part for
Because it simplifies the assembly work, it is an extremely excellent idea as a suspension device for ceiling inspection openings, etc.
