BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin-made holding device in which a pair of holding pieces are connected in an openable manner and an article can be held between holding portions by a spring acting between the holding pieces. is there.

[0002]

2. Description of the Related Art Japanese Patent Publication No. Sho 56-17029 and No. 59
No. 29645, and 6 for small ones.
There is 3-40231. These inventions discuss how to rationally and easily couple a pair of holding pieces with a small number of parts.Especially, the latter one has a pair of holding members having the same shape to simplify manufacturing equipment and work. Is disclosed. However, its structure is special and cannot be converted to large ones. In addition, the first one is suitable for large size, but the number of parts is large, the productivity may be low due to the need for washers, and the middle one is also suitable for large size, but the structure of the pair of holding members is different, There was also a risk that the spring would come off.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and its object is to form the shaft coupling portion into the same shape and structure so as to facilitate molding and assembly, and to provide a shaft coupling portion. The point is that the parts are not shaken and there is no danger of coming off.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a shaft connecting means for connecting a pair of holding pieces so as to be openable and closable, comprising an axially projecting shaft tube, a coaxial tube, A shaft hole to be rotatably fitted is formed in a portion on the opening and closing shaft by resin molding, and each shaft cylinder and the shaft hole are fitted together to axially couple a pair of holding pieces, and the shaft of each holding piece is formed. A shift preventing member for preventing the directional movement is attached between the two shaft connecting portions, and means for engaging the slip preventing member and the shaft connecting portions of the respective holding pieces with each other are taken.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The holding device of the present invention is made of resin, and a pair of holding pieces are connected in an openable manner, and a spring acting between the two holding pieces is used to hold the object between the holding portions. It has a configuration that can be pinched.

[0006] As a shaft connecting means for connecting the pair of holding pieces so as to be able to open and close, a shaft cylinder protruding in the axial direction and a shaft hole rotatably fitted to the coaxial pipe are provided with opening and closing shafts for each holding piece. The upper part is formed by resin molding. That is, since each holding piece has a shaft cylinder and a shaft hole on the opening and closing shaft, respectively, by fitting the shaft cylinder of one holding piece to the shaft hole of the other holding piece, a pair of holding pieces, The shafts are connected at the shaft connecting portions formed by fitting the two shaft cylinders and the shaft holes.

Further, in a state where the two holding pieces are connected to each other, a stopper for preventing each holding piece from moving in the axial direction is attached between the two connecting pieces. The slip preventing member is engaged with the shaft hole and the shaft cylinder of each holding piece. The slip preventing member is interposed between the two shaft coupling portions, so that each holding piece cannot be moved in the axial direction. The shape and structure of such a stopper member are not limited, since the stopper member keeps the pair of holding pieces integrally. In the case where a spring having a coil-shaped portion is used, the slip preventing member also serves as a portion for fitting the ring portion of the spring acting on both holding pieces. The spring is not limited to a helical spring, and any spring such as a flat spring that is bent and used can be used.

[0008] The holding device of the present invention is composed of a pair of holding pieces having a common basic shape, and thus has an advantage of being easy to manufacture including a mold design and easy to assemble. . However, even though the pair of holding pieces have a common basic configuration and shape, they need not be exactly the same shape. For example, one of the holding pieces may have a portion that is not present in the other.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail below with reference to the illustrated embodiments. The illustrated holding device 10 has a holding portion 11 at each end.
And a pair of holding pieces 14 and 15 having, at the other end, an operating portion 13 which is axially coupled at an intermediate fulcrum and applies a compressive force to the elastic force of a spring 12 acting in a direction to close the holding portion 11. Are openably and closably coupled at a shaft coupling portion. One of the holding pieces 14 has, at the tip of the holding section 11, an extension 17 having a small hole 16 through which a hook of a hanger or the like can be hooked. The holding portion 11 of the other holding piece 15
Is in contact with the holding portion 11 of the mating holding piece 14 within a range not covering the small hole 16.

[0010] The holding pieces 14 and 15 are both assumed to be manufactured by injection molding of plastic, so that they are closed at the tip holding section side and the operating section 1 is moved from the shaft connecting section.
Reference numerals 3 and 13 each have a substantially Y-shaped frontal shape that is opened right and left. See FIG. Each of the holding pieces 14 and 15 has a substantially U-shaped cross-sectional shape at each part, thereby increasing rigidity, and is designed to have a hollow shell structure when combined at the rising portions 18 and 18. I have. See FIG.

As a shaft connecting means 20 for connecting the pair of holding pieces 14 and 15 to each other so as to be openable and closable, a shaft cylinder 21 protruding in the axial direction and a shaft hole 22 rotatable by being fitted thereto are provided.
It is formed at a rising portion 18 on the opening / closing axis. The shaft cylinder 21 is set such that when fitted into the shaft hole 22, the end 23 protrudes from the outer surface of the shaft hole, and the shaft connection is sufficiently stabilized. The protruding amount of the end portion is equal to or larger than that of the protruding edge portion 24 provided around the holding portion.

A shift preventing member 25 for preventing the axially connected holding pieces 14 and 15 from moving in the axial direction is provided by a shaft connecting means 2.
Attached between 0 and 20. Exemplary slip prevention member 25
Are a pair of shafts 26a, 2 having a substantially T-shaped cross section in the axial direction.
6b, each of which has a large-diameter and small-diameter shaft portion that fits with each other. The large diameter shaft portion is dimensioned to be inserted into the ring portion 12a wound several times of the spring. Further, in order to engage the slip preventing member 25 with the shaft coupling portions of the holding pieces 14, 15, the protrusions 28, 28 engageable with the cylinder holes 27, 27 of the shaft cylinders 21, 21 are axially outwardly arranged. Is provided.

Therefore, the holding device 10 of the present invention comprises a pair of holding pieces 1.
Since it is constituted only by the spring 12 and the slip prevention member 25 in addition to 4 and 15, manufacture and assembly can be easily performed. In addition, since the stopper member 25 is engaged with the shaft connecting portion of each of the holding members 14 and 15, the holding members 14 and 15 can be combined without play, and the spring 12 can be fixed to the stopper member 25. it can.

[0014]

Since the present invention is constructed and operates as described above, not only is it easy to mold and assemble, but also it is practically used as one which does not loosen the shaft coupling portion and does not come off. It is possible to enhance the performance and to assure a stable and stable operation even as a relatively large holding tool.
