Description

[Detailed Description of the Invention] The present invention relates to the improvement of a device for installing a recessed lighting fixture installed in a system ceiling. An opening 5 for housing the embedded lighting fixture is formed between the installation bars 1 of the system ceiling 3, and the above-mentioned openings are formed on the left and right sides of the horizontal frame 6 from which the embedded lighting fixture is suspended from the center. A pair of support legs 7 placed on the construction bar 1 forming the construction bar 5 are installed in a row to form a fixture A, and the support legs 7 are connected to a lower support leg 9 having a U-shaped horizontal cross section. It is formed with an inverted U-shaped upper support leg 8 which is disposed within the lower support leg 9 so as to be vertically movable, and is formed with holes spaced apart in the vertical direction on the opposite side plates 12 of the lower support leg 9. An upper support leg 80 and both vertical pieces 10 are attached to any one of the plurality of pairs of locked parts 13.
The distance between the height adjusting means C that adjusts the height of the support leg γ by removably inserting and engaging the locking pieces 11 extending outwardly from the lower end thereof and the erection bar 1 of the opening 5 The length adjustment means B for adjusting the length of the horizontal frame 6 by moving the support leg 7 along the horizontal frame 6 in a corresponding manner is attached to the above-mentioned mounting tool A.
The installation of recessed lighting fixtures that fit within the equipment is related to the installation.

In conventional recessed lighting equipment, a metal plate is bent into an inverted U-shape as shown in Fig. 1 to form a fixture A' for mounting the recessed lighting equipment. A pair of support legs 7' of A' were respectively placed on the erection bars 1 incorporated into the system ceiling 3, and an embedded lighting fixture was hung from the horizontal frame 6' of fixture A'.

However, in such a device, manufacturing efficiency is reduced because fixtures A' must be manufactured to install the supporting legs 7' and the horizontal frame 6' with different lengths depending on the model of the recessed lighting fixture. Furthermore, there is a problem in that even if an error occurs when attaching fixture A' to the installation bar 1 of the system ceiling 3, the error cannot be absorbed.

The present invention was developed in view of the above points, and its purpose is to be able to freely change the length dimensions of the support legs and the horizontal frame, and to adjust the length of the support leg and horizontal frame to suit the type of recessed lighting equipment. Recessed lighting can improve the manufacturing efficiency of recessed lighting fixtures by eliminating the need to manufacture support legs and horizontal frames, and can absorb mounting errors when mounting fixtures on the system ceiling. Appliance installation consists in providing equipment.

Hereinafter, the present invention will be explained in detail based on examples.

The system ceiling 3 is composed of a ceiling panel 2 and an installation bar 1, and an opening 5 for storing an embedded lighting fixture is formed between the installation bars 1 of the system ceiling 3.

For installation of recessed lighting equipment, tool A is the installation bar 1 of the opening 5.
A horizontal frame 6 on which the embedded lighting fixture is suspended, and a horizontal frame 6 that is mounted on the left and right sides of this horizontal frame 6 and placed on the construction bar 1. It is configured with a pair of support legs 7 in a ■ shape.

The support leg 7 is formed of an upper support leg 8 and a lower support leg 9 that are connected to each other by a height adjustment means C, and the height adjustment means C includes an upper support leg 8 bent in an inverted U shape. each vertical piece 10
A pair of locking pieces 11 extending outward from the lower end of the lower support leg 90 are connected to one of several pairs of locked portions 13 provided at intervals in the vertical direction on both side plates 12 facing each other. Notches 14 are provided on both the left and right edges of the locking piece 11, and the locked portion 13 has a slit hole 15 with approximately the same length as the width of the locking piece 11. are formed on both side plates 12 of the lower support leg 90, and a drop groove 16 communicating with the insertion slit hole 15 is provided to form a substantially T-shaped through hole. The action of engaging the upper support leg 80 is to bend both vertical pieces 10 inward, insert the locking piece 11 into the insertion slit hole 15, and insert the locking piece 11 into the notch 14 of the locking piece 11.
is aligned with the insertion slit hole 15, and then the locking piece 11 is dropped into the drop groove 16, and the insertion slit hole 15
It is notched diagonally.

The support leg 7 configured as described above is attached to the horizontal frame 6 by the length adjustment means B, and the length adjustment means B is the upper part of the horizontal piece 1T and the pair of vertical pieces 10 of the support leg γ. The left and right sides of the horizontal frame 6 are inserted into the insertion portion 19 formed by the frame member 18 installed between them, and the tightening screws 20 are screwed onto the horizontal pieces 17 of the upper support leg I. The horizontal frame body 6 is tightened and fixed.

At the center of the horizontal frame 6, a threaded rod 21 for suspending an embedded lighting fixture is vertically installed.

A locking groove 4 is provided at the lower end of the support leg T, and this locking groove 4 is fitted into the construction bar 1 to prevent the fitting A from shifting.

As described above, this invention forms an opening for storing lighting equipment between the installation bars of the system ceiling, and creates the above-mentioned openings on the left and right sides of the horizontal frame from which the embedded lighting equipment is suspended from the center. A pair of support legs placed on the bar are attached to form a ■-shaped fixture, and the support legs are moved along the horizontal frame in accordance with the distance between the construction bars of the opening. The above-mentioned installation tool is equipped with a length adjustment means for adjusting the length of the horizontal frame body and a height adjustment means for adjusting the height of the support legs. The length dimensions of the frame and support legs can be varied, so there is no need to manufacture fittings for mounting the support legs and lateral frames with different lengths depending on the type of recessed lighting fixture. It has the advantage of being able to improve the manufacturing efficiency of the fixture, and even if there is an error when attaching the fixture to the support bar of the system ceiling, the installation error can be absorbed, making it easy to embed in the system ceiling. The advantage of installing lighting equipment is that it can be done smoothly.

Further, the support leg is formed by a lower support leg and an upper support leg disposed within the lower support leg so as to be vertically movable, and a plurality of pairs of upper and lower locked portions are bored in both side plates of the lower support leg. Since the locking piece at the lower end of the vertical piece of the upper support leg is detachably engaged with either pair of the upper support leg, the locking piece of the upper support leg can be selectively engaged with the locked part of the lower support leg. The height dimension of the support leg can be adjusted by engaging the upper support leg and the lower support leg, and the locking piece rests on the lower edge of the opening of the locked part after the upper support leg and lower support leg are engaged. It has the advantage that the upper support leg can be supported without shifting, and the height of the support leg does not change due to the load of the lighting equipment.
