Claims

[Claims for Utility Model Registration] 1. An operating frame 15 is pivotally attached to the fixed side bracket 11 via a pivot 16 so as to be rotatable in the vertical direction, and an elevating side bracket 13 is attached to the operating frame via a pivot 17.
The fixed side bracket and the elevating side bracket are connected to pivots 18 and 1 below the operating frame, respectively.
The pivots 18 and 19 of the auxiliary frame are located on the lifting side relative to the pivots 16 and 17 of the operating frame, respectively, when the operating frame is in the horizontal position. The frame is made up of three component members 21, 22, 21, each having a substantially square or square cross section, connected and fixed by a connecting member 23 in a state where they are arranged in parallel, and the central component 22 is connected to a lifting side bracket 13.
A pressing device 25 is installed between the protruding end 24 and the lifting bracket, and the pressing device causes the operating frame 15 to move evenly on both sides in the direction of raising the lifting bracket. A lifting aid device characterized by being pressed at all times. 2. The lifting auxiliary device according to claim 1, wherein the distance between the pivots 18 and 19 of the auxiliary frame 20 is slightly longer than the distance between the pivots 16 and 17 of the operating frame 15. 3 Fixed side bracket 11 and lifting side bracket 1
3 are connected by an auxiliary lever 34 via pivots 35 and 36, respectively, and the pivots 35 and 3 of the auxiliary lever
The distance between the pivots 36 and 36 is the same as the distance between the pivots 16 and 17 of the operating frame 15, and the distance between the pivots 35 and 3 of the auxiliary lever is
6 is on the same plane as the pivots 16 and 17 of the operating frame when the operating frame is in a horizontal position, and is located on the lifting side relative to the pivots 16 and 17 of the operating frame, respectively. 1. The lifting assist device according to 1. 4. A gas spring with a locking mechanism that can be locked at any position is used as the pressing device 25, and a hook portion 37a is formed at one end of the lock operation lever 37 of the gas spring, and a hook portion 37a is formed on the fixed side bracket 11. Hook part 37
By providing an engaging portion 11a corresponding to a, and operating the lock operation lever 37 so that the gas spring is locked when the elevating side bracket 13 is in the raised position, the hook portion 37a of the lock operation lever 37 can be moved to the fixed side bracket. Claims 1-1 characterized in that the device is adapted to engage with the engaging portions 11a of 11.
3. The lifting auxiliary device according to any one of 3.
