[Field of Invention]
The present invention relates to a detachable wing body rotation support structure in which a wing body such as a door or a lid can be detached from a fixed frame body such as a box body as required.
[0002]
[Prior art]
In the conventional normal hinge, the rotating side blade attached to the wing body and the fixed side blade attached to the fixed frame body are connected by a shaft pin that has been prevented from coming off, so the wing body is fixed to the fixed frame body via the hinge. After installing the wing body, it is impossible to remove the wing body from the fixed frame body unless the shaft pin retaining process is released or the fixed side wing plate or fixed side wing plate is not released. Since it takes a considerable amount of time, the wing body is not easily attached and detached.
[0003]
In the pivot hinge disclosed in Japanese Patent Application Laid-Open No. 2000-291316, as the wing body can be easily attached and detached with good workability, the shaft hole of the upper surface plate portion and the shaft of the lower surface plate portion fixed to the wing body are used. The shaft pin is inserted into the hole so as to be movable up and down, and the shaft pin is moved and urged by a spring in a direction in which the tip end portion of the shaft pin protrudes from the shaft hole of the upper surface plate portion and engages with the shaft hole of the fixed frame body. The side plate has a vertical contact hole, a horizontal upper locking hole that intersects the upper end of the communication hole, and a horizontal lower locking hole that intersects the lower end of the communication hole. An operation member that selectively engages with the upper locking hole and the lower locking hole is projected from the side surface of the shaft pin.
[0004]
In order to place the pivot hinge on the upper part of the wing body and attach the wing body to the fixed frame body, the holder is fixed to the end of the wing body on the suspension side, and the operating member is engaged with the main portion of the lower locking hole. By fitting, the wing body is fitted into the front opening of the fixed frame body in a state where the tip end portion of the shaft pin is retracted to the upper surface position of the wing body.
After that, when the operating member is pulled from the lower locking hole and moved to the intersection of the lower locking hole and the communication hole, the shaft pin moves upward due to the bias of the spring. Move to the intersection of the holes.
[0005]
When moved upward, the tip of the shaft pin protrudes from the upper surface position of the wing body, engages with the shaft hole of the fixed frame body, and supports the wing body rotatably with respect to the fixed frame body.
Finally, by engaging with the main portion of the operating member upper locking hole, the shaft pin is held at a position where the tip end portion is engaged with the shaft hole of the fixed frame body. The engagement state between the operation member and the upper locking hole is maintained by pressing the side surface of the operation member against the inner wall surface of the upper locking hole by the biasing of the spring.
[0006]
[Problems to be solved by the invention]
As described above, the vertical connecting hole provided in the side plate portion of the holder, the horizontal upper locking hole intersecting the upper end portion of the connecting hole, and the horizontal lower engaging member intersecting the lower end portion of the connecting hole. The stop holes are an important functional element for positioning the shaft pins by cooperating with the operation member on the shaft pin side. However, in order to achieve the function accurately and smoothly, these holes are accurately positioned. And need to be formed into a shape.
[0007]
In manufacturing the holder, each hole and contour shape is punched and formed in a metal plate material by pressing, and then each side plate is bent at a predetermined angle. It is not easy to secure, and the plate portion between the upper locking hole and the lower locking hole is distorted and deformed, or burrs are generated such that the operating member is caught at the edge or intersection of each hole. Probability of non-defective products is relatively high. When such a malfunction occurs, repairing and bending of the edge of each hole is required, resulting in high costs.
[0008]
Therefore, an object of the present invention is to easily remove and attach the wing body with good workability, and to eliminate a hole for engaging and disengaging the operation member on the shaft pin side from the blade plate, so that a product that operates accurately and smoothly can be easily and inexpensively. It is an object of the present invention to provide a detachable wing body rotation support structure which can be manufactured.
