Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a blind spot confirming mirror device, and more particularly, to a blind spot confirming mirror device with improved mounting stability.
[0002]
[Prior art]
Since a convex mirror has a function of projecting a reflected image at a wide angle, it is widely used as a means for checking a state such as a blind spot. For example, it is used for preventing shoplifting in stores such as convenience stores and supermarkets, and for preventing collisions at the corners of passages where people come and go, such as in factories and stations. In order to confirm the state of the blind spot as described above, it is necessary that the inclination angle of the convex mirror with respect to the vertical direction and the horizontal direction can be adjusted.
[0003]
Conventionally, as a method of attaching the convex mirror so that the tilt angle can be adjusted as described above, as shown in FIG. 4, one end of the flexible tube 32 is fixed to the back of the convex mirror 31 and the other end is attached to the support base 33. In some cases, the support 33 is fixed to a ceiling 34 or a wall surface while being fixed. However, according to this mounting method, when an object hits the convex mirror 31 or a strong wind blows the pressing force F to the convex mirror 31, a bending moment is generated in the flexible tube 32, and the support 33 is moved to the ceiling 34. In some cases, peeling may occur such that the support 33 rises at the portion A, and the support 33 may eventually fall off the ceiling 34.
[0004]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems and to provide a blind spot confirming mirror device that can reliably support a convex mirror even when an object hits the convex mirror or strong wind acts. .
[0005]
[Means for Solving the Problems]
The blind spot confirmation mirror device of the present invention that achieves the above object has a support base fixed to a ceiling, a support rod can be pivoted around the axis on the support base, and the support rod hangs down from the upper end side as a fulcrum. And a convex mirror is attached to the lower end of the support rod so that the inclination angle can be adjusted.
[0006]
The support rod of the convex mirror is made rotatable with respect to the support base fixed to the ceiling in this manner, and is suspended so as to be able to swing sideways with respect to the support base. Even when a pressing force acts in the direction, the pressing force is released by the lateral deflection of the support rod, so that separation of the support from the ceiling can be prevented. Further, since the convex mirror is attached to the lower end of the support rod so as to adjust the inclination angle and the support rod itself is rotatably supported, the blind angle can be projected over a wide range by adjusting the inclination angle.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail with reference to an embodiment shown in the drawings.
[0008]
1 and 2 show a blind spot confirmation mirror device according to an embodiment of the present invention.
[0009]
In the figure, 1 is a convex mirror, 2 is a support rod, and 3 is a support base. A flange 4 is attached to the rear surface of the convex mirror 1, and the flange 4 is attached to a plate portion 5 at the lower end of the support rod 2. That is, the flange 4 of the convex mirror 1 is superimposed on the plate portion 5 of the support rod 2, a bolt 6 is inserted horizontally so as to penetrate the flange 4 and the plate portion 5, and a nut 7 is inserted into an end of the bolt 6. Are screwed together and tightened and fixed. With such a mounting structure, when the nut 7 is loosened, the convex mirror 1 is rotated around the bolt 6 (pivot shaft), and the mounting inclination angle can be adjusted arbitrarily.
[0010]
The support 3 is formed from a hollow box and is fixed to the ceiling 12 with screws 8. A stupid hole 9 is provided at the center of the bottom surface of the box of the support base 3, the upper end of the support rod 2 is inserted into the stupid hole 9, and a stopper 10 is fixed to the upper end with a screw 11 and is prevented from falling off. That is, the diameter of the stopper 10 is made larger than the diameter of the stupid hole 9 so that the support rod 2 does not fall out of the support base 3.
[0011]
As described above, the support rod 2 is attached to the support base 3 so as to hang down via the stupid hole 9 so that the support rod 2 is rotatable about the axis and is wobble with the upper support portion as a fulcrum. It is possible to swing back and forth, right and left. Further, the support rod 2 capable of swinging in such a manner is connected to the ceiling 12 by one to three linear members 13. The linear body 13 is not always necessary, but can suppress a large lateral deflection of the support rod 2 and can attenuate it quickly when a lateral deflection occurs. Although the material of the linear body 13 is not particularly limited, for example, a steel wire, a fiber cord, or the like can be used, and a coil spring or a rubber string that can be elastically expanded and contracted can be preferably used.
[0012]
Although not essential in the present invention, as shown in FIGS. 3A and 3B, a plurality of radially uneven grooves 14 are provided on the lower surface of the stopper 10, and the same radially uneven grooves are formed on the support base. The support rod 2 can be prevented from rotating if it is provided on the bottom surface of the box 3 so as to mesh with each other. When changing the position of the support rod 2 in the circumferential direction with respect to the support table 3, the relative position can be changed by slightly lifting the support rod 2 upward, rotating it by a required angle, and then lowering it.
[0013]
As described above, the blind spot confirmation mirror device of the present invention enables the support rod 2 of the convex mirror 1 to be rotatable around the axis with respect to the support table 3 fixed to the ceiling 12 and to be lateral to the support table 3. Since the support rod 2 is suspended so that it can swing, even if a large pressing force acts on the support rod 2 due to, for example, an object hitting the convex mirror 1 or blowing a strong wind, the support rod 2 applies the pressing force to the side. You can escape by shaking. Therefore, the support 3 is not separated from the ceiling 12. Further, since the convex mirror 1 is attached to the lower end of the support rod 2 so as to adjust the inclination angle, and the support rod 2 itself can rotate around the axis, by adjusting the inclination angle according to the blind spot, The blind spot can be projected over a wide area.
[0014]
The blind spot confirmation mirror device of the present invention can be used as, for example, a convenience store, a supermarket, etc., for preventing shoplifting, for preventing collision at a corner of a passage in a factory or a station yard, or as various other means for confirming a blind spot. it can.
[0015]
【The invention's effect】
According to the present invention as described above, the support rod of the convex mirror is made rotatable with respect to the support fixed to the ceiling, and is suspended so as to be able to swing sideways with respect to the support. Even when a horizontal pressing force acts due to an object hitting, the pressing force is released by the lateral swing of the support rod, so that separation from the ceiling of the support table can be prevented. Further, since the convex mirror is attached to the lower end of the support rod so as to adjust the inclination angle and the support rod itself is rotatably supported, the blind angle can be projected over a wide range by adjusting the inclination angle.
