Description

[Detailed description of the invention] <Industrial field of application> This invention relates to an improvement of a corner hanger in which suction cups are rotatably attached to both ends of a single rod-shaped body.

<Prior Art> Corner hangers in which suction cups are rotatably provided at both ends of a rod-like body and can be suctioned and fixed toward two orthogonal walls are already commercially available.

<Problems to be solved by the invention> To explain the disadvantages of the conventional corner hanger using Fig. 3, after pressing the suction cup A against the wall B and fixing it, the rod-shaped body C is moved around the axis of the suction cup A. Rotate the other suction cup D close to another wall E, and when it is close enough, press the suction cup D against the wall E at almost a right angle and fix it.
The suction cup rotates too freely, and the direction of the suction cup D easily changes while the suction cup D approaches the wall surface E, and the lip part touches the wall surface E, so the direction must be adjusted frequently or the direction must be changed. It took a lot of effort, as I had to hold it to make sure it wasn't there. Also, the direction in which the suction cup D is pushed against the wall surface E for adsorption,
Since the direction of rotation of the suction cup D through the rod-like body C, which does not change in length, does not match, the position at which the suction cup D ends pressing is slightly shifted from the initial position where the suction cup D is pressed against the wall surface E, and the suction cup D does not rotate. Since the suction cup D was displaced while being dragged, it was difficult to obtain a good suction effect.

The purpose of this invention is to provide a corner hanger that can solve the above two problems.

<Means for solving the problem> This invention consists of a tongue piece that has a bulge on the top surface and cutouts with appropriate gaps between the two protrusions of the support member that fixes the suction cup. The bulging portion imparts a rotational braking force to the connecting member by the reaction force of the tongue portion which bends when pressed against the outer peripheral surface of the base of the connecting member rotatably provided between the two overhanging portions. In addition, a long hole along the longitudinal direction is formed in the connecting member, and protrusions that engage with the long hole are provided at both ends of the rod-shaped body. In this way, the intended purpose is achieved by making it possible to press the suction cup against the wall surface by linearly extending the rod-shaped body.

<Example> This invention will be explained with reference to an example shown in the drawings. 1 is a known suction cup, and the head 2 has a rectangular shape.
A mounting hole 3 is bored in the hole. The suction cup 1 is attached to the support member 4. For this purpose, the support member 4 is formed with a rectangular surrounding wall 6 into which the pin 5 can be inserted from the outside, and after fitting the head 2 of the suction cup 1 into the surrounding wall 6, the pin 5 is inserted into the mounting hole 3. By inserting the suction cup 1 in this manner, the suction cup 1 and the support member 4 are joined together.
In order to reliably bring the suction cup 1 into close contact with the wall surface, it is desirable that the suction cup 1 be pushed not only at its center but also at its outside. Therefore, in the illustrated example, two arc-shaped vertical walls 7, 7 are provided oppositely on the outside of the surrounding wall 6, and the two arc-shaped vertical walls 7,
Several hemispherical protrusions 8 are formed on the end face of the support member 7, and a conical skirt wall 9 corresponding to the lower end of the support member 4 is formed further outside the vertical walls 7, 7, thereby forming a hemispherical shape. The suction cup 1 can be pushed by the protrusion 8 and the skirt wall 9.

The support member 4 not only mounts the suction cup 1, but also rotatably connects the connecting member 16 with the connecting pin 10. For this purpose, protruding parts 12, 12 in which insertion holes 11, 11 for the connecting pins 10 are formed are protruded from the upper end of the support member 4, and the base of the connecting member 16 is provided between the protruding parts 12, 12. By inserting the connecting pin 10 after inserting the support member 4 and the connecting member 16, a rotatable connection between the supporting member 4 and the connecting member 16 is achieved.

A part of the wall between the two protruding parts 12, 12 of the support member 4 is formed into an easily deformable tongue part 14 obtained by cutting out parts 13 with appropriate gaps on three sides, and the upper surface of the tongue part 14 has a bulge. A protruding portion 15 is formed. This bulge 15
In the assembled state, is pressed by the outer circumferential surface of the base of the connecting member 16, causing the tongue portion 14 to bend as shown in FIG. As a reaction force, a braking force that prevents the connecting member 16 from rotating freely is applied to the connecting member 16.
will be empowered.

A long hole 17 is formed in the connecting member 16 along the longitudinal direction. This elongated hole 17 engages with a protrusion 19 of an end member 18 that is slidably inserted into the inside of the connecting member 16, thereby allowing the end member 18 to move by a length equivalent to the elongated hole 17. . The vicinity of the protrusion 19 of the end member 18 has the same structure as the tongue portion 14 of the support member 4 described above, and is bent when pressed.
When inserting into the connecting member 16, even if the protrusion 19 is present, there is no problem. A pipe-like rod 20 serving as a hanger is fitted onto the end member 18.

Although only one side has been described above, since the opposite side has exactly the same structure, the explanation will be omitted. Also,
Although not shown, the end member 18 is omitted and the rod-shaped body 20 is slidably inserted directly into the connecting member 16, and pins are implanted in place of the protrusions 19 of the end member 18. You may also set it.

<Effects of the invention> According to this invention, once the orientation of the suction cup 1 with respect to the rod-shaped body 20 is set by the rotational braking force of the connecting member 16 exerted by the tongue portion 14 of the support member 4, the orientation of the suction cup 1 with respect to the rod-shaped body 20 can be changed. can be maintained reliably. Therefore, after fixing one suction cup 1 to one orthogonal wall surface, setting the rod-shaped body 20 at a desired angle, and adjusting the other suction cup 1 so that it directly faces the other wall surface, then There is no possibility of it rotating freely. Moreover, since the rod-shaped body 20 can be extended in the longitudinal direction within a length corresponding to the elongated hole 17, it is possible to extend it straight and press the suction cup 1 against the wall, eliminating the need to drag the suction cup 1 as in the past. It is extremely convenient because it is possible to easily achieve good fixation using No. 1 without any trouble.
