Clip that opens with little force

Abstract

When you want to securely clip and store documents, use a clip with a strong spring. While it would be desirable to have a selection, elderly people often struggle to open the clip and take out the documents. [Solution] The tip of the clip has a ring-shaped bend in the axial direction at the point of application. Bring the fulcrum closer and use the grip of the pressure arm as the point of force application to clip with a weak force. I made it so it could be opened.

Summary of the Invention

Problems to be Solved by the Invention

[0004] When securely clipping and storing documents or the like, a clip with a strong spring is desired, but for the elderly, when opening the clip to take out the documents it is quite laborious because the finger strength is weak.

Means for Solving the Problems

[0005] At a specific position in the axial direction close to the center of the fulcrum axis of each pressing arm connected in two parts at the tip of the clip, a ring-shaped bending process in the axial direction of the pressing arm is performed, the fulcrum of the R part of the ring-shaped bending process in the axial direction is brought closer to the action point at the tip of the clip, and with the grip part of the pressing arm as the force point, the clip can be opened with a weak force. When the pressing arm made by the mechanism of Claim 1 is extended to the storage state, the two pressing arms interfere with each other and the dimension in the height direction becomes large. To solve this problem, the attachment angles of the left and right pressing arms to the clip body were shifted 5 degrees to the left and right respectively to eliminate interference.

Advantages of the Invention

[0006] The clip can now be opened with even a weak force.

Claims

1. The pivot axis of each of the two pressure arms connected to the tip of the clip The ring-shaped bending process in the axial direction of the pressure arm is performed at a specific position in the axial direction near the center. The clip's tip is bent in an axial direction into a ring-shaped curve. The fulcrum was brought closer, and the grip portion of the pressure arm was used as the point of force application. A clip that opens with minimal force, thanks to its lever principle.

2. When the pressurizing arm created by the mechanism of claim 1 is extended and stored, The two pressure arms interfere with each other, increasing the height dimension. To resolve this, the mounting angles of the left and right pressure arms to the clip body were adjusted to the left and right respectively. A clip that opens with minimal force, characterized by its 5-degree offset to eliminate interference.
