Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lighting fixture mounting bracket, and particularly relates to a fixture that allows a lighting fixture to be mounted in any direction to a prismatic or cylindrical support member in lighting equipment for orchards and the like.

Conventionally, this type of lighting fixture mounting bracket was installed by wrapping a flat iron with multiple square holes around a cylinder of any external shape, or by attaching a pair of dogleg-shaped metal fittings together to make the same shape as the square pillar. A rectangular type is used, or a circular type with a pair of semi-circular metal fittings joined together to make the outer shape of the cylinder the same, but the flat iron type described above is only used when the diameter of the cylinder is large to a certain extent. Furthermore, when installing square and circular lamps on a square column, the installation direction is restricted, and the lighting equipment cannot be installed in any direction, resulting in the disadvantage that efficient illumination cannot be achieved.

The present invention was developed in view of the above-mentioned drawbacks, and includes a plurality of L-shaped metal fittings slidably attached to the inner periphery of a frame body consisting of a pair of semicircular arc-shaped metal fittings, and the outer shape of the supporting member is square, circular, or round. The supporting member of any of these modifications can be set at an appropriate position that matches the external shape of the supporting member, and an efficient one that can be attached to these supporting members with the same mounting bracket and whose mounting direction can be adjusted arbitrarily. To provide a lighting fixture mounting bracket that provides good illumination.

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

In FIG. 1, reference numeral 1 denotes a cylindrical support member installed in an orchard, etc. A pair of mounting brackets 2 are fastened and fixed on the outer periphery of this support member 1 in a spaced-apart manner. Support arms 3 are respectively protruded from one side, and the support arms 3
Both ends of a lighting device 4 such as an insecticidal lamp 4a are supported at the tip of the lamp.

As shown in FIGS. 2 and 3, the mounting bracket 2 integrally includes a semicircular curved portion 5a and flat fixing portions 5b and sb protruding outward from both ends of the curved portion 5a. Two semi-circular arc-shaped metal fittings 5 are formed by bending, and the opening sides thereof are opposed to each other.
A substantially circular frame body 8 is formed by connecting the screws b with bolts 6 and nuts 7 as connectors so that the tightening can be freely adjusted in the approaching and separating directions. L-shaped metal fittings 9 are slidably attached to the frame body 8 with respective bent corners 9a protruding inward.

As shown in FIG. 4, the L-shaped metal fitting 9 is bent at a right angle at one place to form an abbreviated shape, and one end of the L-shaped metal fitting 9 is slidably fitted into the metal fitting 5 of the frame body 8. A rectangular fitting hole 10 is formed, and a notch 10a is formed in the middle of one end of the fitting hole 10 so as not to engage with the support arm 3.

The L-shaped metal fitting 9 is attached to the frame body 8 by fitting the fitting hole 10 from the end of the metal fitting 5 and sliding it to the curved portion 5a.

Further, each of the L-shaped metal fittings 9 is attached so as to be oriented in the same direction with respect to the circumferential direction of the frame body 8,
As shown in FIG. 2, each bent corner 9a is
It is designed to be fixed in contact with the outer periphery of the

Next, a case will be described in which the mounting bracket 2 is fixed to the cylindrical support member 1.

With the bolts 6 and nuts 7 removed, attach two L-shaped fittings 9 to each of the pair of fittings 5, and
are located on the outer periphery of the support member 1 and connected to each other with bolts 6 and nuts 7 to hold the mounting bracket 2 on the support member 1.

Then, by rotating the mounting bracket 2 to arbitrarily adjust the orientation of the support arm 3 that supports the lighting fixture 4, and tightening the bolt 6, each of the four L-shaped brackets 9 will be folded as shown in FIG. The curved corner portion 9a comes into pressure contact with the outer periphery of the support member 1 and is firmly fixed.

Next, a case will be described in which the mounting bracket 2 is fixed to the prismatic support member 1'.

Attach one L-shaped metal fitting 9 to each metal fitting 5, totaling two
L-shaped metal fittings 9 are used.

In the same way as when attaching to the cylindrical support member 1 described above, the mounting bracket 2 is held on the support member 1', the mounting angle of the mounting bracket 2 is determined arbitrarily, and the bolt 6 is tightened, and two L-shaped brackets are attached. 9 slides along the frame body 8, and as shown in FIG. The frame body 8 is in pressure contact with the support member 1'
It is circumscribed at four places and is firmly fixed.

Although the L-shaped metal fitting 9 in the above embodiment has a notch 10a formed at one end of the fitting hole 10 as shown in FIG. 4, it is also possible to form only the fitting hole 10 without the notch 10a. good.

According to the present invention, a plurality of L-shaped fittings are slidably attached to a substantially circular frame body formed by connecting a pair of semicircular arc-shaped fittings in a tightening-adjustable manner on the inner periphery of this frame body. Since the bent portions of the plurality of L-shaped metal fittings are circumscribed with the support member, when the mounting metal fittings are fitted to the support member, adjusted to an arbitrary angle, and the frame body is tightened, the support member becomes angular. In the case of a columnar shape, the L-shaped metal fitting moves freely along the frame body, fits in the flat part of the support member, and circumscribes the support member at each bent corner, and if the support member is cylindrical, it is L-shaped. Since the L-shaped metal fittings are fixed in contact with the outer periphery of the support member at each bent corner, the L-shaped metal fittings can be slid against the support member regardless of the shape of the support member, such as prismatic, cylindrical, or modified shapes. It can be moved and set at an appropriate position that matches the external shape of the support member, and it can be securely and firmly attached to these support members using the same mounting bracket, and the mounting bracket can be fixed in any direction relative to the outer periphery of the support member. This eliminates the need to prepare separate mounting brackets for prismatic support members and cylindrical support members when installing lighting equipment in large areas such as orchards, and allows the lighting equipment to be installed in any direction. This allows for efficient lighting.
