Description

  The present invention relates to a clothespin in which components are simplified without using a metal spring.

  Conventionally, the structure of a clothespin that has been widely used is to generate a pair of opening and closing pieces composed of a holding portion, a support shaft portion, and a handle portion, and a holding force of the opening and closing pieces. It is comprised by three components of the spring which has shapes, such as a metal substantially C shape, couple | bonded with a spindle part.

  In this conventional clothespin, a pair of opening and closing pieces are manufactured with each molded product, and a spring is manufactured with metal or the like, and the parts are assembled. There is still room for further simplification and cost reduction by improving the structure.

  In addition, when conventional clothespins are discarded, assuming that the majority of current products are incinerated, flammables and metals that cannot be reused are left behind and become industrial waste. Or, considering that the reuse of resources, which has been promoted since the end of the 20th century, will continue to be promoted, it is assumed that the clothespins must be separated into resin molded products and metal springs. Yes, but in this case, human labor will be required, and it will take time to implement thoroughly because it is an inefficient work.

  As an improvement measure, a pinion force of a pair of opening and closing pieces in a conventional clothespin is generated, and the metal spring parts necessary for connecting the opening and closing pieces at the support shaft portion are eliminated, By providing a one-body structure with a leaf spring added to one side of the opening and closing, and having a form having a receiving portion of the leaf spring on the other side, and adding a mechanism for coupling to the support shaft itself, The number of components can be simplified to only two, the manufacturing process can be simplified and the cost can be reduced, and the material of the components can be unified into a single type, which also helps to reuse resources.

  The problem to be solved is to eliminate the metal spring parts of the clothespins and to provide a means for simplifying the components while retaining the substitute function of the spring parts.

  The present invention has a one-body structure in which a leaf spring is added to one of a pair of opening and closing methods constituting a clothespin as a means having a function of substituting the spring component, and a leaf spring is attached to the other. The main feature is that it has a configuration having a receiving portion and has a structure such as insertion and fitting in the support shaft portion as means for connecting the opening and closing pieces.

  The present invention has the advantages that, by the above-described means, the component parts can be simplified to only two points of the opening and closing pieces, and the material of the parts can be unified into a single type.

  By using a single-body structure with a leaf spring added to one of the pair of opening / closing methods, which is a part of the clothespin, as usual, centering on the support shaft connected to the other opening / closing piece In addition, opening and closing by the action of a spring was realized.

  In carrying out the present invention, the material used is harmless in daily life, has durability, has elasticity, and can be reused. The materials that are enumerated in the conditions and are assumed to be made of a resin having characteristics that satisfy the conditions or a metal that has been processed, are considered to be one of the materials, and consideration is given to the reuse of resources.

  FIG. 1 is an external view of a first embodiment of the present invention, wherein 1 and 2 are open / close pieces constituting a clothespin, each having a holding portion 3a, 3b, a handle portion 4a, 4b, 1 and 2 are joined together at 5 spindle parts. 6 is a plate-like spring and has an integrated structure with 1.

  The first embodiment of the present invention is configured as described above and has the same function as a conventional clothespin with only two components.

  FIG. 2 is a structural view of a connecting portion related to the support shaft portion 5 in FIG. The hinges 7 and 8 are combined to secure a sufficient space for the rotation of the support shaft portion. The 7 side has 9 fitting shafts and the 8 side has 10 fit holes, and the support shaft rotational motion. The center of Reference numeral 5 denotes a support shaft portion, and 11 denotes a support of the support shaft portion, which doubles as 7 to 10 reinforcement and protection.

  A conventional spring having a shape such as a substantially C-shaped metal made of clothespins also plays a role of coupling the holding force of the opening and closing pieces at the support shaft portion. As a result, it is possible to simplify the components such as one embodiment of the present invention, simplify the manufacturing process and reduce the cost, and use a single type of material for the components. Can be unified.

  FIG. 3 is an explanatory diagram relating to the clamping portions 3a and 3b in FIG. 1, and particularly relates to claim 3.

  In FIG. 3, the leading portions 12a and 12b are provided at the leading ends of the sandwiching portions 3a and 3b, and the subsequent protrusions 13a and 13b are arranged. The shape of the projection is similar to that of a shark's teeth, and is designed to be easy to insert and difficult to pull out so that the clothes that are washed are not easily pulled out. It can be used also by the operation of inserting the clothing etc. if the use conditions are ready.

  Simplifies the manufacturing process in the production of clothespins, lowers production costs, and makes it easy to reuse resources because parts can be unified into a single material when discarded. It is also useful for environmental conservation.

It is explanatory drawing which showed the implementation method of clothespins. Example 1 FIG. 2 is a structural diagram of a coupling portion related to the support shaft portion of FIG. 1. Example 1 It is explanatory drawing which showed the implementation method which concerns on the clamping part of the said FIG. (Example 1)
