JP3029947U - Floodlight having a holder that can be instantaneously fixed - Google Patents

Abstract

(57) [Abstract] [PROBLEMS] A holder for fixing a floodlight quickly, safely, easily, surely, and capable of freely changing the illumination angle, and fixing it with a simple structure. Think of parts so they can be reused. SOLUTION: The holder of the projector is provided with an L-shaped clamp (1).
By doing so, the fixed body is sandwiched and fixed instantly. The direction of the projector (11) uses a curved tube in which two ball joints (12, 15) are built in the movable holder (8). By closing one holding handle (9). The two ball joints in the curved pipe are tightened from the surroundings to be in close contact with each other and securely fixed. Therefore, the lighting angle can be changed freely. The L-shaped clamp can also be used as a general tool by removing the lock nut (24).

Description

[Detailed description of the device]

TECHNICAL FIELD The present invention relates to a holder for a floodlight.

[Prior Art] Conventionally, a floodlight of this type has a rail portion (2) on a vise (23) shown in FIG. 4 and a tightening handle (6) is turned to rotate an angle plate (4) and a vise (4). The fixed body is sandwiched between 23) and fixed so that the direction of light is fixed by turning two hands in the vertical direction (19) and the horizontal direction (20).

[Problems to be Solved by the Invention] When the projector is attached to a small fixed body among those described in the related art, the tightening handle (6) must be rotated by a fine screw thread. For example, when fixing to a fixed body of 6 mm, the screw thread has about 50 pitches and it cannot be fixed unless the tightening handle (6) is rotated about 50 times. Further, in the case of a deformed fixed body, when the tightening handle (6) is tightened, stress concentrates on the elongated spindle (5), which tends to cause bowing. Even if it is fixed for a long period of time, it is likely to deform and malfunction. Further, there are two handles, a vertical fixed handle (19) and a horizontal fixed handle (20) for changing the direction of light, which often takes time and is a troublesome work. That is, the conventional floodlight has a problem that it is troublesome. When the projector is hung downwards, the lateral fixed handle (20) has a right-hand screw when the projector is turned counterclockwise, and it rubs against the vice connecting rod (18), so it may loosen and fall out by itself when there is vibration. It was dangerous.

The present invention has been made in view of the above problems of the prior art. The purpose of the present invention is to secure the projector easily, quickly and securely, and to prevent the projector from falling off. The present invention provides a holder for a simple floodlight. It also contributes to work safety and quality improvement.

[Means for Solving the Problems] In order to achieve the above object, the holder of the projector according to the present invention is an L-shaped clamp (1) as shown in FIG. 1 and has an arm (3). It slides up and down along the rail part (2), and the fixed body is instantly sandwiched between the adjustable plate (4) and the tightening handle (6) is rotated to fix it.

In order to match the direction angle of light, the movable holder (8) is used at the connecting portion between the L-shaped clamp (1) and the projector main body (11), and the direction of the projector main body (11) can be freely adjusted. It can be instantly fixed with the holding handle (9).

[Embodiment of the Invention] The embodiment of the invention will be described with reference to FIG. 1. An L-shaped clamp (1) is provided, and an arm (3) slides vertically along a rail portion (2). When the fixed body is instantly sandwiched between the freely rotatable plates (4) and the tightening handle (6) is turned, the spindle (5) and the penetrating part of the arm (3) are fixed because of the screw part. .

The movable holder (8) shown in FIGS. 1, 2 and 3 has a curved tube provided with an upper lid (13) and a lower lid (16) and a fixing plate (17) integrally provided with a fixing nut (10). Has become. The inner diameter surfaces of the upper lid (13) and the lower lid (16) are chamfered so as to fit the spherical surface. Notches are formed from the upper surface lid (13) to the innermost shortest portion of the curved pipe and the lower surface lid (16). Two balls (12, 15) are fitted exactly inside the bendable tube of the movable holder (8). Two balls (12, 15) are integral with each connecting rod (22, 7). The inner diameter surfaces of the upper lid (13) and the lower lid (16) and the connecting rods (22, 7) each have a proper space and can move freely, and the two balls (12, 15) inside the curved pipe are exposed. It does not seem to come out.

The curved pipe of the movable holder (8) shown in FIGS. 1, 2, and 3 may be a straight pipe. In that case, the operating range of the projector is narrowed.

The holding handle (9) has a bolt (14) thinner than the fixing plate (17) than the handle shaft. Since the tightening part is on the center side of the inner circumference of the curved pipe, when the holding handle (9) is tightened, the two balls (12, 15) inside the curved pipe of the movable holder (8) are tightened from the surroundings and are in close contact. Will be securely fixed. In other words, one holding handle (9) can be fixed vertically and horizontally.

In order to improve the state of the two balls (12, 15) inside the curved pipe fixed and adhered to each other, a slip stopper having a large frictional resistance may be used.

The clamp connecting saloon (7) and the L-shaped clamp (1) can be used as a general tool by removing the lock nut (24) from the L ramp (1).

[Advantages of the Invention] Since the present invention is configured as described above, it has the following effects.

The L-shaped clamp according to claim 1 can be securely fixed instantaneously with a simple structure.

By using the ball joint in the movable holder according to the second aspect, it is possible to quickly determine the illumination position and instantly fix it with one handle, and the projector main body does not fall off.

The L-shaped clamp of claim 3 can be used as a general tool by removing the lock nut. That is, when the projector main body is broken, the parts are not wasted.
