持装置。[Claims for Utility Model Registration] 1. A load 3 that can be raised and lowered freely along a lifting path formed by several supporting members 1 arranged vertically,
In a mechanical support device for holding a load 3 at a predetermined position without obstructing the upward movement from a fixed position below the lifting path to a predetermined position above, the support member 1 is provided at a predetermined upper position. A support arm 23 made of a substantially rectangular plate member having a long dimension in the vertical direction is rotatably attached to the support pin 22 at approximately the center in the longitudinal direction of the support arm 23 . A substantially rod-shaped detachment link 24 having a vertical dimension longer than that of the support arm 23 is also pivotably attached to the lower end portion of the support arm 23 at approximately the center of its longitudinal direction. A wear link 26 made of a substantially isosceles triangular plate member having two upper and lower hypotenuses 26 1 and 26 2 is rotatably connected at its upper end, and its lower end is located below the support pin 22 . In the support member 1
The attachment link 26 has a detachment link 2 at approximately the center thereof.
The lower ends of 4 are connected to each other so as to be longitudinally movable and rotatable, and the tension coil springs 32 are connected to the upper and lower ends of the support arm 23 and the support member 1 at positions above and below the support pin 22, respectively. The wear link 26 is arranged so that its upper and lower hypotenuses 26 1 and 26 2 face the lifting path of the load 3, and the load 3 is connected to the wear link 26 in the ascending process. The support arm 23 , removal link 24, and attachment link 26 have their center lines S-S above the center of the support pin 22 at all times. The attachment link 26 is attached to its lower hypotenuse 26 1 and pivotably thereto as the load 3 increases. When the support arm 23 comes into contact with the tension coil spring 40 , the support arm 23 is pivoted around the support pin 22 so that its upper part projects into the lifting path of the load 3 , and at the same time the center of the tension coil spring 32 is rotated. A mechanical automatic support device in which the line S-S moves beyond the center of the support pin 22 to the other side. 2. The mechanical automatic support device according to claim 1, wherein the release link 24 is formed with a hook portion 241 near its upper end, which faces the lifting path of the load 3. 3 The kicker 40 is composed of a substantially rectangular plate member, and is freely pivotable to the load 3 via the kicker hinge 41 arranged horizontally perpendicular to the lifting path and parallel to the support member 1. In this case, KITSUKA 40
The weight on the side closer to the support member 1 is greater than the weight on the other side, and the load 3 is applied to prevent the rotation of the kicker 40 based on this weight difference. 3. The mechanical automatic support device according to claim 1, further comprising a stripper 42 for contacting the upper surface of the tensioner hinge 41 on the side remote from the support member 1.
