Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support device used to support curved mirrors and other objects.

Traditionally, at curved corners in indoor hallways in schools and other places, there is a risk that people coming from both sides will collide with each other.

In order to avoid such dangers, curved mirrors have traditionally been installed, but conventional rod support devices that support such mirrors generally have a ball joint at the base end of the rod. In most cases, the joint part is secured to the fixed part using bolts or other fastening means to prevent the joint part from coming off.

In such a support device, the ball joint part can swing freely within the movable range of the joint holder, so it has the advantage of being able to easily change the position of the mirror, but the movable range is limited and the joint part and joint If there is any looseness between the mirror and the holder, the mirror will move unnecessarily and will no longer be fixed in a fixed position.

In addition, it is not limited to mirrors, but for example, when a support rod with a ball joint at the base end is used to attach a lighting device to the tip, the mechanism is exactly the same as described above, and especially if the lighting device at the tip is heavy, the initial Even if it is fixed in position with an adjustment bolt or the like, there is a problem in that the mounting position gradually changes due to its weight during use.

Furthermore, in the case of mounting an audio device or the like, changing the mounting position may cause problems such as a significant adverse effect on the acoustic effect.

In view of this, the present invention was made with the purpose of providing a support device that can be applied not only to supporting curved mirrors but also lighting equipment, audio equipment such as speakers, television cameras, etc. It consists of a sliding support to be attached, a support rod, and a support member, and the sliding support can move or rotate with respect to the support rod, and the support rod can slide up and down and rotate left and right with respect to the support member. As it is movable, it has far more directional freedom than conventional support devices.
Moreover, it is easy to change, has a simple structure, can be manufactured at a significantly low cost, and furthermore, does not loosen after tightening and change the mounting position.

This is because it is a support device for curved mirrors and the like.

Hereinafter, the present invention will be described with reference to embodiments shown in the drawings.

In FIG. 1, the support rod 1 is made of a single pipe or a solid round bar, and one end thereof is bent at right angles to the axis of the support rod 1 to form a mounting base 1a.

The other end is perpendicular to the mounting base 1a, and
It is formed in a curved rod portion 1b that is bent into a substantially semicircular shape with an appropriate radius of curvature R.

A support member 2 for fixing the mounting base 1a at one end of the support rod 1 to a wall surface, pillar, etc. is attached by welding or other means to the center of a square seat plate 2a having mounting holes such as bolts at the four corners. It has a fixed straight pipe 2b, into which the mounting base 1a is inserted.

This straight pipe 2b has an inner diameter slightly larger than the outer diameter of the support rod 1, and a length shorter than the seat plate 2a, so that the seat plate 2a is attached to a fixed part with a bolt (not shown) or the like. When fixed, the support rod 1 can be supported in the straight pipe 2b so as to be rotatable in the left-right direction and slidable in the vertical direction.

Further, in the center of the straight pipe 2b, there is a hole for screwing in a push screw 3 for fixing the support rod 1 at an arbitrary position,
A nut) 2C is welded around the hole to form a female thread, and by screwing a push screw 3 into this nut 2C, the support rod 1 can be fixed at any position in the vertical direction and in the left-right rotation direction. It is now possible to do so.

A sliding fixture 4 for attaching a mirror or the like is fitted into a substantially semicircular curved rod portion 1b at the other end of the support rod 1.

The sliding fixture 4 has a short pipe part 4a that can be fitted onto the support rod 1, and a mounting seat 4 for attaching a mirror or the like to the short pipe part 4a.
b, the short pipe portion 4a has an inner diameter larger than the outer diameter of the straight pipe 2b of the support member 2, and the other end of the support rod 1 has a curved rod portion 1b having an approximately semicircular shape. It has an inner diameter that can be slid arbitrarily along the semicircular portion when it is fitted onto the outside.

In this embodiment, the mounting seat 4b is constructed by arranging L-shaped pieces back to back at regular intervals, and is fixed by welding or other means in the axial direction of the short pipe part 4a, and is attached to a seat parallel to the axial center. Surface 4C
is formed.

This seat surface 4C is provided with mounting holes, respectively.
Utilizing this, curved mirrors, lighting equipment, and other objects can be attached to the seat surface 4C using bolts or other fastening means.

Further, a punch hole is provided on the outside of the short pipe portion 4a,
By screwing a push screw 5 into this screw hole, a sliding fixture 4 such as a mirror can be fixed at any position on the curved rod portion 1b of the support rod 1.

This fixture 4 has the following features in the curved rod portion 1b of the support rod 1:
By loosening the push screw 5, it is possible to slide to any position along the semicircular shape of the curved rod portion 1b, and also to rotate at any position.

The above-mentioned sliding fitting 4 has been explained as being composed of a short pipe portion 4a and a mounting seat 1b consisting of a pair of L-shaped pieces, but this is made of a single plate as shown in the second figure. Short pipe part 4
a and the mounting seat 4b may be constructed integrally and tightened with a set screw 5.

Since the present invention is constructed as described above, first, the mounting base 1a of the support rod 1 is inserted into the straight pipe 2b of the support member 2, which is fixed to a column or the like with four bolts (not shown). After determining the vertical position and the rotation position in the horizontal direction, it is fixed with the set screw 3.

Next, on the seat surface 4C of the sliding fixture 4 that is fitted onto the semicircular curved rod portion 1b at the other end, a curved mirror or other devices that require similar support, such as lighting equipment, television cameras, and audio equipment, are attached. , and other devices are secured by bolts or other fastening means.

Then, the fixture 4 is moved to the most appropriate location on the curved rod portion 1b, and if necessary, rotated up and down to find the optimal position, and then fixed with the set screw 5.

Even in this state, if it is necessary to change the height position or swing the head, the mounting base 1a of the support rod 1 can be used to adjust the vertical and horizontal rotational directions.
Adjustments can also be made with this.

Therefore, the present invention can eliminate the drawbacks of the conventional method, in which the device is set only in a limited movable range using a ball joint or the like, and the mounting position becomes loose due to backlash.

That is, one end of the support rod is bent into a substantially semicircular shape to form a curved rod portion, and a sliding fixture is fitted to this portion so that its position can be changed in a direction close to 180°. By fixing it at a desired position, it can be adjusted over a very wide range, so the degree of freedom in mounting is extremely large and the adjustment is also easy.

Furthermore, according to the embodiments shown in FIGS. 1 to 3, the fixation to the support rod is achieved by screwing in the push screw, and the tip of the push screw presses the support rod, so that the fixation to the support rod is made strong, and heavy objects can be firmly fixed to the support rod. Even when supporting, it can be supported reliably without loosening.

In addition, the outer diameter of the support rod is somewhat smaller than the inner diameter of the short tube section because the short tube section of the fixture is moved in the almost semicircular curved rod section, and when the support rod is pressed with the push screw, The inner wall of the short pipe section and the outer surface of the support rod normally make point contact, but in this embodiment, since the diameter of the support rod is smaller than that of the short pipe section, when the tip of the push screw touches the outside of the support rod. It is eccentric to the support rod and moves slightly inside the short tube section, and as a result, the inner wall on the opposite side of the short tube section and the outer surface of the support rod come into line contact, increasing the frictional force and further loosening the tube. is less likely to occur.

The above explained the case where a sliding fixture is fitted to the curved part of the support rod and a curved mirror or the like is supported on this fixture, but if the object to be supported needs to be adjusted greatly, , Attach a curved mirror etc. to the mounting base side of the support rod,
It may be used by fixing the fixture on the curved part side of the support rod to a pillar or the like.
