Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to an opening and closing spring pressing device for a cover sheet. [Known technology] For example, on a stereo device, a panel with an adjustment button that is used less frequently is usually covered with a cover. The cover sheet is kept closed by a staggered latch device, and at the same time, a device that is formed by combining a penetrating device and a damper that encapsulates lubricating oil and is pressed in the opening direction is set appropriately. Opening speed, and can improve high quality. (Refer to Japanese Shikai No. 4-11 9078). [Problems to be Solved by the Invention] However, the structural device / proposal proposed in the above publication is a force that often acts on the cymbal as a movable member to urge in the opening and closing direction. Therefore, the latch device used to maintain the closed state of the cover is Indispensable. Therefore, in addition to the complicated structure and difficulty in reducing the number of parts, it is difficult to reduce the manufacturing cost because the positional accuracy of the interlocking device must be improved to meet the requirements of the closed position. The present invention was developed by a developer to solve the conventional technical problems. The main purpose of the invention is to provide an opening and closing spring pressing device for cover sheets, which can simplify the structure and reduce the manufacturing cost. [Solution to the problem] In order to achieve this objective, the cover device of the present invention Shen Peihong # + A "Month Patent Dry Enclosure Item 丨 is provided with a fixed member (frame member 2); Component (arm member 3); the elastic device that can strengthen the movable structure braking device H; and the elastic device that imparts the rotational resistance of the movable component to the former....

Description of the invention (3) Printed on the paper by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, the paper standards are applicable to the Zhongguanjia Standard (CNS) A4 rule_ 格 ⑵〇x 297 公 f 丁 3 to the rotation axis of the arm member 3 (pivot Contact 4) The common sleeve supports rotation and displacement. Then, the outer side m of the cover sheet L in the first figure is strongly closed along the vertical shape of the vertical plane ~ '° This state is feared' the torsion spiral elastic 9 tends to expand the inner angle of the two extensions 9b and 9c to exert elastic force. The elastic force remains closed. If the cover piece L is opened in this state, the two extension portions 9b and 9b of the torsion coil spring 9 will be made before a certain angle. The inner angle narrows and exerts a spring force that prevents it from opening. After exceeding a certain angle, as shown in Figure 3, the elastic force of the torsion coil spring 9 will be reversed to the opening direction, and then the elastic force of the torsion coil spring 9 in the opening direction will be transmitted to the cover sheet Lji, and the rotation damper 6 The proper turning resistance is applied to perform the opening action at an appropriate speed. In the fully opened position of the cover sheet L, the torsion coil spring 9 exerts an elastic force toward maintaining the open state. Conversely, when the cover sheet L is closed, the elastic force of the torsion coil spring 9 can play a role before a certain angle to maintain the tendency to open, but when the closing angle of the cover sheet L exceeds a certain angle, the torsion coil spring 9 acts on the cover sheet. The elastic force of B is reversed to the closing direction. Thereafter, the rotational force of the torsion coil spring 9 is transmitted to the cover sheet L, and the opening operation is performed at an appropriate speed in accordance with the appropriate rotational resistance given by the rotational damper 6 '. · '[Effect of the invention] According to the present invention, since the positions of the two extension ends of the helical coil spring can be appropriately set to reverse the direction of the spring force, the position of the cover fully closed or fully open can be determined by the frame and The stopper between the covers is set, so it is not 312539 IIIIII — III — — — -III — — — — ^ 11111111 (Please read the precautions on the back before filling this page) 499537
