下降窓開閉補助具
Document Type and Number:
Japanese Patent JP7183220
Kind Code:
B2
Abstract:
To provide a descending window opening and closing auxiliary tool that enables smooth opening and closing operation and facilities installation with a compact structure by reducing a sudden increase in load due to a repulsive force of a spring that is generated from a closed state to a fully open state.SOLUTION: A descending window opening and closing auxiliary tool 1 includes a main body 2 disposed below a descending window, and an arm 4 provided so as to be rotated up and down. The arm 4 includes a roller 4a in contact with a lower end of the descending window at a distal end thereof. A rotational force input from a gear 12 provided at a center of rotation of the arm 4 is inverted to a reciprocal motion of a rack 14 through an intermediate gear 16. A compression spring 8b is provided in a compressed state by a stopper 8a restricted by a guide 8c, at a spring unit 8 connected to the rack 14. A compression spring 6 is disposed in series with the compression spring 8b. A repulsive force of the compression spring 6 is transmitted to the compression spring 8b through the stopper 8a.SELECTED DRAWING: Figure 1
