Description

  The present invention relates to scissors used by hand, and particularly to scissors in which the entire blade portion is covered with a cover.

  A variety of scissors used by hand, from school children to those that are practically used by ordinary adults, have been proposed. In many cases, it is a form that is natural when viewed as an article, so there is almost no impact caused by unexpectedness based on a change in form.

  Therefore, as proposed in Patent Document 1, for example, “It can be stored compactly in a writing instrument case, etc., and there is no danger of opening the blade part when carrying it, and a complicated operation is performed. There is a “portable bag” for the purpose of “providing a portable bag that can be easily restored to a use form without having to do so”.

Utility Model Registration No. 3161126 Publication

As shown in FIG. 7, the scissors described in Patent Document 1 are
“A pair of blade portions, a pair of handle portions extending at the rear end portions of the pair of blade portions, and a blade portion and the handle portion are provided between the blade portions and the handle portion, and the pair of blade portions can be rotated. In a state in which the pivot shaft that is pivotally supported, the biasing member that is mounted on the pivot shaft and biases the pair of blades and the handle in the opening direction, and the pair of blades are closed, It is formed of a cover portion that can store the blade portion and can hold the blade portion in a closed state, and has an overall bar shape with the cover portion attached. ''
It has a pen shape when not in use, and becomes “scissors” when in use, and has a strong impact caused by unexpectedness based on changes in form.

  However, the “portable bag” of this Patent Document 1 has a shape of a “pen cap” when the pair of handle portions are closed as shown in FIG. In order to fit semi-cylindrical objects into a complete cylinder, they have different shapes. For this reason, in order to manufacture each handle | pattern part of this portable bag, a separate type | mold will be needed and it will be thought that it may cost.

  Further, in the “portable bag” of Patent Document 1, as shown in FIG. 7, the biasing member 16 is exposed during use, so that cut paper waste and yarn waste are easily caught. In addition, if the user is an infant, there is a possibility that the biasing member 16 that has been exposed may be mischievously removed.

  Furthermore, in the “portable bag” of Patent Document 1, the torsion part of the biasing member 16 that is exposed when used is fitted to the rotating shaft part, and the end part is merely inserted into each handle part. For this reason, a fitting structure must be formed on the “rotating shaft” itself, and the urging member 16 may be easily detached.

Therefore, the present inventors, for this type of scissors,
(1) To reduce the cost so that the handle portion attached to the attachment portion of each blade body can be formed with one type of mold.
(2) Whether the spring is in a closed state or in a used state, all or most of the spring is within the handle so that something is not pinched or easily detached.
(3) The pivot should not be used as a spring locking part, and should remain as a conventional simple one.
As a result of various investigations on what should be done, the present invention has been completed.

  That is, the object of the present invention is to satisfy the above-mentioned demands (1) to (3), and to create a scissors having a strong impact due to unexpectedness based on a change in form by a simple structure. It is to provide.
