TECHNICAL FIELD OF THE INVENTION
The present invention relates to a support device for a swing structure.
[0002]
[Prior art]
FIG. 6 shows a conventional example of a supporting device used to rotatably support a lighting device or a display device of a personal computer around a predetermined pivot axis. In this conventional example, a lighting device or the like (swirl structure 1) has a swivel shaft 2 and a guide shaft 4 parallel to the swivel shaft 2, and a supporting device 9 fixed to the installation base 8 by appropriate means includes: A shaft support portion 3 through which the turning shaft 2 is inserted and a guide groove 5 through which the guide shaft 4 is inserted are formed.
[0003]
The turning structure 1 is rotatable about the turning shaft 2 in a state of being fixed to the support device 9, and the rotation angle θ is regulated by the guide groove 5.
[0004]
[Problems to be solved by the invention]
However, in the conventional example described above, since the turning angle of the turning structure 1 is determined by the guide groove 5 formed in advance in the support device 9, for example, when the wall surface 10 or the like interferes with the turning range, It is necessary to separately prepare a supporting device 9 in which the guide groove 5 is designed so as to regulate the turning angle of the turning structure 1 within a range where the occurrence does not occur, and there is a problem that versatility is lacking.
[0005]
SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-described drawbacks, and provides a swing structure support apparatus that can freely set a swing angle of the swing structure and has improved versatility. The purpose is to:
[0006]
[Means for Solving the Problems]
The turning structure 1 mounted on the support device 9 has the turning shaft 2 and the guide shaft 4 inserted into the shaft support portion 3 and the guide groove 5 so as to be rotatable around the turning shaft 2. The turning angle is restricted by the moving range of the guide shaft 4.
[0007]
The guide groove 5 can be closed at an arbitrary position by fixing the groove closing member 7 to the closing member mounting portion 6 formed on the support device 9. Therefore, in the present invention, since the rotation angle of the turning structure 1 can be arbitrarily set by arbitrarily closing the guide groove 5, versatility is improved.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 shows a support device 9 for supporting a display device (swivel structure 1) of a personal computer on a wall surface 8. The display device 1 includes a display unit 1a formed by a liquid crystal display device and the like, and a bending arm 1c that can be bent around an appropriate number of joints 1b. The shaft 4 protrudes.
[0009]
The support device 9 includes a main body 9a having a box shape, and a closing plate (groove closing member 7) detachable from the main body 9a. The main body portion 9a can be fixed to the wall surface 8 at a fixing portion (not shown) formed on the side wall portion, and the shaft support portion 3 that supports the turning shaft 2 is formed on the upper surface of the main body portion 9a. The shaft support 3 can be formed as a simple cylindrical body through which the rotating shaft 2 on the display device 1 side cannot be detached and rotatably inserted, or can be formed as a rotating shaft to which the rotating shaft 2 can be connected and fixed.
[0010]
A guide groove 5 into which the guide shaft 4 can be fitted is formed on the upper surface of the main body 9a. As shown in FIG. 2A, the guide groove 5 has an arc shape concentric with the shaft support 3 so as to allow the movement of the guide shaft 4 accompanying the rotation of the turning shaft 2.
[0011]
Further, a plurality of closing plate mounting holes (closing member mounting portions 6) are formed along the guide grooves 5. One closing plate mounting hole 6 is formed in each of the inside and outside directions of the guide groove 5 on a pitch line equally dividing the guide groove 5 at a predetermined pitch angle p.
[0012]
On the other hand, as shown in FIG. 2 (b), the closing plate 7 is formed in an arc shape having the same curvature as the guide groove 5, and has a guide shaft passing notch 7a with one end closed and a guide shaft passing notch 7a. As shown in FIG. 2 (a), the guide shaft passage notch 7a is formed in a state in which the mounting hole 7b is aligned with the closing plate mounting hole 6 of the main body 9a, as shown in FIG. It matches the guide groove 5.
[0013]
The closure plate 7 can be fixed to the main body 9a by various methods. For example, as shown in FIG. 3B, a rivet 11 made of synthetic resin is pressed into the closure plate mounting hole 6. Or by screwing.
[0014]
Therefore, in this embodiment, at the time of shipping, as shown in FIG. 2A, the closing plate 7 is mounted at a terminal position where the guide groove 5 is not closed, and the wall surface is mounted with the display device 1 installed. In the case where a collision occurs, as shown in FIG. 4, the turning angle is restricted from θ to θ ′ by once removing the closing plate 7 and fixing the closing plate 7 at an appropriate position again. In addition, it is possible to easily prevent contact with a wall surface or the like.
[0015]
FIG. 5 shows another embodiment of the present invention. In this embodiment, the groove closing member 7 is formed of a synthetic resin material, and as shown in FIGS. 5A to 5D, a disk-shaped closing plate portion 7d having a knob 7c protruding upward. Having. On the other hand, the guide groove 5 is formed with a large-diameter portion serving as the closing member attaching portion 6 at a predetermined pitch, and the closing plate portion 7 d is formed to have a larger diameter than the diameter of the large-diameter portion 6. On the back surface of the closing plate portion 7d, there is formed a stopper oval portion 7e whose major axis is slightly longer than the diameter of the enlarged diameter portion 6, and a further oval shape is formed on the back surface of the stopper oval portion 7e. A bottom wall stopper 7f is provided.
[0016]
The thickness (h) of the stopper oval portion 7e is substantially equal to the thickness of the ceiling portion of the main portion 9a. First, as shown by an arrow A in FIG. When the knob 7c is rotated horizontally after insertion, the stopper oval portion 7e is fitted into the enlarged diameter portion 6 of the guide groove 5 while bending as shown by an arrow B in FIG. Maintain a rotating posture. In this state, since the groove closing member 7 sandwiches the ceiling of the main body 9a by the bottom wall stopper 7f and the closing plate portion 7d, the groove closing member 7 does not fall out of the guide groove 5, and as a result, the moving range of the guide shaft 4 is reduced. Acts as a restricting interferer.
[0017]
In the above description, a case is described in which the use of one groove closing member 7 restricts a turning angle from a predetermined one end of the guide groove 5 to a range in which the groove closing member 7 is mounted. However, when two groove closing members 7 are used, it is possible to freely determine the turning end on both sides.
[0018]
【The invention's effect】
As is apparent from the above description, according to the present invention, since the turning angle of the turning structure can be set freely, the versatility can be improved.
