<Third Embodiment> FIGS. 7 to 12 show a tilt stand 10 according to a third embodiment of the present invention. The same components as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

The present embodiment does not have the lock members 28 and 31 as in the first and second embodiments,
The base 11 and the mounting table 12 have a structure including a releasable lock mechanism having the same function.

That is, as shown in FIG.
A cut groove 33 is formed around the stopper protrusion 23 in three directions so as to surround the stopper protrusion 23 on three sides, and a cantilevered tongue portion 35 whose one end base portion 35a is connected to the mounting table 12 is mounted on the mounting table. The structure is provided integrally with the 12.

Then, as shown by a virtual line in FIG.
Due to the flexibility of the resin material that constitutes the mounting table 12, the one end base portion 35a can be bent and deformed upward as a center.

On the upper surface of the free end portion 35b of the tongue piece portion 35, a bending deformation regulating portion 36 having an appropriate height is provided so as to project.
Then, when the free end portion 35b of the tongue piece portion 35 is pushed upward, the tongue piece portion 35 comes into contact with the lower surface of the object to be placed mounted and fixed on the mounting table 12 so as to be separable. The amount of flexural deformation is regulated, and excessive flexural deformation is effectively prevented. In this case, the stopper protrusion 23 is configured so as to secure a bending deformation amount capable of overcoming the stopper wall portion 17.

A fitting hole 3 as a fitting part having a shape corresponding to the stopper projection 23 is provided at an appropriate position in the circumferential direction over the one stopper wall 17 in the recess 14 of the base 11.
9 is formed.

When the mounting table 12 is rotated around the support shaft portion 15 in a predetermined direction, the stopper projection 23 and the stopper wall portion 17 are brought into contact with each other. In this state, the free end portion 35b of the tongue piece portion 35 exposed on the lower surface side of the mounting table 12 is inserted between the base 11 and the mounting table 12 by inserting a finger into the opening surrounded by the cut groove 33. When the finger is pushed up through the stopper wall 23, a state in which the stopper protrusion 23 is retracted above the stopper wall 17 is obtained. In this state, if the mounting table 12 is further rotated around the support shaft portion 15, the stopper protrusion 23 will move the stopper wall portion 17 to the stopper wall portion 17.
Get over.

When the push-up operation of the tongue piece 35 is released in this overriding state and the mounting table 12 is further rotated in the same direction, the tongue piece is located at the position where the stopper projection 23 and the fitting hole 39 are aligned. Due to the elasticity stored in the portion 35, the stopper projection 23 is fitted in the fitting hole 39, and the tongue piece 35 returns to the initial state. When the stopper projection 23 is fitted into the fitting hole 39, the tilt adjustment and the swivel adjustment of the mounting table 12 are locked.

If the tongue piece 35 is pushed up again to disengage the stopper projection 23 from the fitting hole 39 and rotated in the opposite direction to the above, the stopper wall portion 17 is overcome, If the push-up operation of the tongue portion 35 is released, the stopper protrusion 2 is initially provided between both stopper wall portions 17.
3 is arranged, and the tilt and swivel adjustments of the base 11 and the mounting table 12 are returned to a state where they can be adjusted.

Further, on both sides of the free end portion 35b of the tongue piece portion 35, as shown in FIG. 12, a rising restraining rib 41 having an L-shaped cross section, which is opposed to the peripheral edge portion of the cut groove 33.
Is integrally formed on the mounting table 12. That is, at the position above the free ends 35b of the two lifting control ribs 41, the tongue portions 35 are formed so as to face each other and project toward the cut groove 33.
The free end portion 35b of the above has a slight gap and is allowed to pass between the two lifting restriction ribs 41.

Therefore, when the mounting table 12 is rotated,
Even if the stopper projection 23 comes into contact with the stopper wall portion 17 and the tongue portion 35 tries to bounce upward by its force, the abutment of the tongue portion 35 causes the tongue portion 35 to lift up to one side.
The phenomenon in which the stopper protrusion 23 inadvertently gets over the stopper wall 17 is effectively regulated because the tongue portion 35 bends in one direction and the upward movement of the free end portion 35b of the tongue portion 35 is regulated by the protruding portion of the regulation rib 41. To be done.

The present embodiment is configured as described above, and the stopper projections 23 are made to come into contact with the stopper wall portions 17 through the flexural deformation of the tongue pieces 35 integrally formed on the mounting table 12.
After being operated, the stopper protrusion 23 is fitted into the fitting hole 39 formed in the base 11, so that the tilt adjustment and the swivel adjustment of the mounting table 12 in a predetermined posture can be easily performed in a locked state. Can be fixed to.

Therefore, as in the case of the first embodiment, it is possible to effectively prevent troublesome work such as positioning by the operator, and improve the work efficiency.

Further, according to the present embodiment, the lock members 28 and 31 for locking are not required separately, and the number of parts can be further reduced.

Further, since the bending deformation restricting portion 36 is provided, it is possible to effectively prevent the damage of the one end base portion 35a due to the excessive bending deformation of the tongue portion 35 during the locking operation or the unlocking operation.

Further, due to the lifting control rib 41,
It is also possible to effectively prevent accidental jumping over of the stopper projection 23 against the stopper wall 17.
