Description

[Detailed explanation of the idea] This invention relates to a buttful support device for lighting equipment.

As is well known, in lighting equipment using fluorescent lamps, a plurality of buttfuls are integrally supported on a support arm, and this is sometimes used by being attached to the lighting equipment.

Conventionally, each buttful is fixed to the support arm by screws or welding, but this makes the installation work complicated and has poor workability.

The purpose of this invention is to simply and reliably fix and support each buttful on a support arm.

An embodiment of this invention will be described with reference to the drawings. Reference numeral 1 denotes a buttful, 2 a support arm, and 3 a connecting arm superimposed on the surface of the support arm 2.

Tongue pieces 4 are formed on both side edges 1A of the full 1,
A hole 5 is formed in this tongue piece 4.

In the illustrated embodiment, indentations are provided on both sides of the tongue 4 in order to align the tip edge of the tongue 4 with the side edge 1A, but this is not necessary.

The support arm 2 has holes 6 along its longitudinal direction at intervals corresponding to the arrangement interval of the buttfuls, into which the tongue pieces 4 can be inserted.
is shaped.

Further, windows 7 are formed in the connecting arm 3 at intervals corresponding to the above-mentioned arrangement interval, and wedge-shaped insertion pieces 8 are formed continuous to one side edge of each window 6. .

The distance between the other side edge 7A of the window and the tip of the insertion piece 8 is such that the tongue piece 4 can pass through.

In the above structure, in order to support each buttful, the tongue piece 4 of each buttful 1 is first inserted into each hole 6.

Next, the connecting arm 3 is placed along the support arm 2, and the tongue piece 4 pulled out from the hole 6 is further inserted between the other side edge 7A of the window 7 and the tip of the insertion piece 8.

Note that in reality, the hole 6, the tip and side edge 7 of the insertion piece 8
Support arm 1 and connection arm 2 so that they match
What is necessary is to overlap them and insert the tongue piece 4 at the same time.

In this inserted state, the tip of the insertion piece 8 is made to face the hole 5 of the tongue piece 4.

Here, the connecting arm 3 is slid relative to the support arm 2, and the insertion piece 8 is inserted into the hole 5.

Since the insertion piece 8 is wedge-shaped as shown in the figure, it can be firmly engaged with the hole 5.

As described above, each buttful 1 is attached to the support arm 2 via the connecting arm 3.

In this attached state, each buttful 1 has its tongue piece 4 inserted into the hole 6 of the support arm 2, so that
The swing of Batsuful 1 is restricted.

Furthermore, since the insertion hole 8 of the connecting arm 3 is inserted into the hole 5 of the tongue piece 4, the buttful 1 does not slip out from the support arm 2.

Therefore, the buttful 1 can be securely and stably attached to the support arm 2.

Further, the installation work is extremely easy since it only requires a slight slide of the connecting arm 3 along the support arm 2 and inserting the insertion piece 8 into the hole 5.

It is also possible to use a simple rod-shaped connecting arm instead of the connecting arm 3 as shown in the figure, but when using such a connecting arm, each buttful 1 pulled out from the hole 6 of the support arm 2 The connecting arm must be inserted into all of the holes 5 in order starting from the end, and this work is much more troublesome than when using the connecting arm according to this invention.

As detailed above, according to this invention, multiple buttfuls arranged in parallel can be attached to the support arm without using screws, welding, etc. as in the past, but simply by attaching them to the holes in the tongue pieces and the windows. It is extremely easy to install as it only requires insertion and sliding of the connecting arm, and since the insertion piece is wedge-shaped, it can be firmly installed, and each installed baffle can be stabilized relative to the support arm. Make the most of your efforts.

In the illustrated embodiment, the tongue piece 4 is provided on the side edge of the buttful 1, but it may be provided on the upper edge.

In addition, in the illustrated embodiment, a pair of tongue pieces 4 are provided, and thus a pair of support arms 1 are provided.
, although the connecting arms 3 are also a pair, they do not necessarily have to be a pair; for example, if the tongue piece 4 is provided on the upper edge of the buttful 1, the support arm 1 and the connecting arm 3 may each be one. .

In short, the tongue piece 4 only needs to be on the periphery of the buttful.
