Abstract

PURPOSE:To provide a gripper which can be attached and detached easily without the generation of a stress strain as a reaction against a load near a spring and the opening of a grip piece, even if heavy load is applied in a degree not exceeding the material strength of a hook in a hang down direction. CONSTITUTION:A grip main body 10 is composed of a first grip piece 11 and a second grip piece 12, which are jointed by a support shaft 15 and closed by an energized spring 17. The first grip piece 11 and the second grip piece 12 have a first grip end 13 and a second grip end 14 formed in a protruded shape and a recessed shape respectively. The hook parts of both grip ends are overlaped so as to engage mutually and the upper part of the gripper becomes a ring shape at its closing time.

2. Description of the Related Art A conventional gripper is of a center aligning type in which two scissors having the same shape face each other and their tips come into contact with each other. Therefore, such a gripper fixes itself by inserting a rod-like cylinder or the like into a ring-shaped portion formed when the gripper is closed.

However, when the center-fitting type spring scissors are sandwiched between cylinders and the object is further hung under the gripper, the object is too heavy or is pulled by a wind or the like in a direction other than the downward direction. However, when the load is larger than the urging force of the spring, the two scissors that are in contact with each other start to open and come off from the column or the like.

However, when a downward load such as hanging an object is applied to such a hook type gripper, the load is supported only by the grip piece having a hook-shaped tip. Therefore, a stress strain occurs in the vicinity of the spring due to the reaction against the load, and if the load is larger than the biasing force of the spring, the hook piece will start to open as in the case of the center aligning type gripper. It was

Further, since the hook type gripper serves as a retaining piece which is different from the grip piece having the hook-like tip, the grip pieces having the hook-like tip can be laid down. Otherwise, there was a drawback that it could not be attached to or removed from the rod.

The present invention has been made in view of the above problems, and an object thereof is to prevent the stress strain as a reaction against a load from being generated in the vicinity of the spring and to improve the strength of the material of the grip piece in the suspending direction. It is an object of the present invention to provide a gripper that can be easily attached and detached without causing the grip piece to start opening no matter how much load is applied to the gripper.

Since the embodiment of the present invention has the above-mentioned structure, when both grip ends are closed, they are overlapped by both hook portions. Therefore, when hanging on a column such as a rod, The force to open the grip generated by the load is not generated. Therefore, for example, when the gripper of the present invention is used by being dropped on a laundry rod, various uses can be considered. By attaching a metal fitting, a vinyl cord, a plastic chain, a string, etc. to the hole 16 in the gripper of the present invention, a hanger and small clothes can be hung under the gripper, and heavy laundry can be dried there. In addition, the laundry rods can be connected to each other by connecting cords using a plurality of grippers, and the laundry can be dried on the connecting cords, so that the laundry shed can be effectively used.
