Japanese Patent No. 3247868

  An object of the present invention is to provide a handle device with a lock function capable of reducing a storage space for a spring for holding a lever in a locked position.

The feature of the present invention is that the main body case fitted into the mounting hole of the opening / closing member leaving the front end flange portion and the side wall of the main body case are elastically deformed and locked to the hole edge of the mounting hole. A side shaft portion is pivotally supported by the claw plate portion and the bearing hole of the side wall of the main body case, and is inserted into the opening portion of the bottom wall of the main body case, and the leg end surface is in contact with the edge portion of the opening portion. A lever that holds the posture of the lock position, a recess that is formed on the distal end side of the lever that penetrates to the back side of the main body case, and that engages and disengages a lock pin provided on the fixed frame side, and a front end portion of the lever The handle plate portion provided, and the bottom wall of the main body case and the handle plate portion of the lever are installed between the handle plate portion, and the lever is urged to rotate toward the lock position where the recess engages with the lock pin. And a posture holding spring In the click function with a handle device,
The posture maintaining spring is constituted by a torsion-type coil spring, and a first spring support portion is provided on the front surface of the bottom wall of the main body case at a portion close to the edge portion of the opening where the leg portion of the lever contacts. A second spring support portion is provided on the back surface of the handle plate portion at a position opposite to the edge portion with respect to the first spring support portion, and the posture holding spring is configured such that the central axis of the coil portion is the lock position Arrange so that it is parallel to the bottom wall of the body case,
A torsional load is applied to the posture holding spring, and when the lever is rotated to a locked position or an unlocked position, one linear portion extending from one end of the coil portion of the posture holding spring is: In the first spring support portion, the other straight portion that rotates around the axis of the straight portion and extends from the other end of the coil portion of the posture holding spring is in the second spring support portion. That is, it rotates around the axis of the straight line portion.

In the handle device with a lock function according to the present invention, the posture holding spring is constituted by a torsion-type coil spring, and the bottom wall of the main body case is located near the edge of the opening where the leg of the lever abuts. A first spring support portion is provided on the front surface, a second spring support portion is provided on the back surface of the handle plate portion at a portion opposite to the edge portion with respect to the first spring support portion, and the posture maintaining spring is coiled. Since the central axis of the part is arranged so as to be parallel to the bottom wall of the main body case at the locked position, that is, the coil part is arranged in a vertical manner in the front-rear direction of the main body case. In addition, one linear portion extending from the coil portion is engaged with the first spring support portion, and the other linear portion extending from the other end portion of the coil portion is the second spring. By engaging the holding portion, a torsional load is applied to the posture holding spring, and when the lever is rotated to the unlock position, each linear portion rotates around each axis in each spring support portion. However, since each linear portion is torsionally deformed so as to approach the coil portion, the spring storage space to be secured between the bottom wall front surface of the main body case and the handle plate portion rear surface of the lever is It is not affected by the size of the outer peripheral diameter of the coil portion of the posture holding spring, and can be reduced as compared with the conventional mechanism of the compression coil spring system.
As a result, there are no restrictions on the miniaturization design for the posture holding spring.
