Description

Improved tilt brackets

The present invention relates to a bracket for supporting and fixing various mechanical parts or devices, and more particularly, to an improved tilt bracket to easily adjust and fix an angle.

In general, the bracket is used to support a shaft, a lever, a shelf, a lighting device, an antenna device, etc. to protrude from a structure or a facility such as a machine body, a wall, a pillar, or the like. Brackets for such applications are required to be able to convert and adjust the angles in order to properly correspond to the placement angle between the structure and the object or to increase the use efficiency of a lighting device, an antenna device, etc., in which directionality is particularly important among the objects.

Tilt brackets of various shapes and structures have been proposed for this request, and the "angle adjustable bracket" disclosed in Korean Patent Laid-Open Publication No. 2004-10422 is an example. This publication is also filed by the applicant of the present invention is shown in Figures 1 and 2, the present invention is part of an improvement therefor.

The bracket of the patent comprises: a base (1) fixed to the structure; A rotatable support portion (2) rotatably contacting the base (1); A spring that penetrates the support portion 2 and the base 1 and a spring disposed in the outer diameter of the head portion of the shaft bolt 4 to elastically compress the support portion 2 and the base 1. It consists of a fastener (3) comprising (5).

In the figure, the support part 2 consists of two parts: an intermediate block 6 which rotates in one direction on the base 1 and a support 7 which rotates again in the other direction on the intermediate block 6. However, depending on the design, the support 2 may be made of one or three or more parts. The more parts constituting the support 2, the finer the adjustment will be possible.

The bracket can, of course, be used to change and adjust the angle. First, loosen the shaft bolt (4) to weaken the elasticity of the spring (5). Then, the pressing force between the support part 2 and the base 1 weakens, and the support part 2 can be rotated from the base 1. In this state, the angle conversion and adjustment of the support 2 can be performed.

After the adjustment is completed, tighten the shaft bolt 4 again to strengthen the elasticity of the spring 5. Then, the pressing force between the support 2 and the base 1 becomes stronger, and the support 2 can be fixed at a predetermined position and angle. It is true that the bracket of this structure enables the conversion and adjustment of the angle, which is particularly useful in the antenna installation field.

According to the conventional bracket structure described above, in order to adjust and fix the angle, the shaft bolts 4 should be loosened or tightened. In this case, a driver or a separate tool should be used. Therefore, the work for adjusting the angle is inconvenient and slow, this inconvenience becomes more severe when the working space is narrow or when working on the ceiling or high walls.

Furthermore, if the object is mounted on the support 2, the shaft bolt 4 may be covered by the mounted object. In this case, the angle adjusting operation may be very inconvenient, of course, even impossible. This is also because the loosening and tightening of the shaft bolt 4, which is a pre- and post-work of adjustment, must be made above the support 2.

The present invention has been proposed to improve the above problems of the prior art. It is an object of the present invention to provide an improved tilt bracket so that the adjustment and fixing of the angle can be made easily and quickly.

The tilt bracket of the present invention is:
