Drawer device
A drawer device or container holder includes a member disposed in a closed position to be able to draw into an open position, a driving device attached to the member to move the member between the closed position and the open position, and a sensing device for sensing whether or not the member is drawn out for a predetermined amount from the closed position. A control device controls the driving device to cause the member to be housed when the sensing device senses that the member is not drawn out for a predetermined amount. Also, a container placed on a tray can be sensed assuredly regardless of vibration during a movement of a vehicle.
1. A drawer device comprising:
a drawer member disposed in a closed position to be able to draw into an open position out of the closed position,
driving means attached to the drawer member to move the drawer member between the closed position and open position, said driving means applying torque to the drawer member through electric current,
a torque limiter disposed between the drawer member and the driving means for limiting the torque applied therebetween,
sensing means for sensing whether or not the drawer member is drawn out for a predetermined amount from the closed position, said sensing means sensing a change in the torque applied by the driving means through a change in the electrical current,
control means connected to the driving means and the sensing means, said control means controlling the driving means to cause the drawer member to be housed when the sensing means senses that the drawer member is not drawn out for the predetermined amount or when torque applied by the driving means exceeds a predetermined value before the drawer member is drawn out for the predetermined amount, and
means for housing the drawer member, said housing means having a fixed shaft therein for pivotally supporting the drawer member so that when the driving means operates, the drawer member is rotated to shift between the closed position inside the housing means and the open position outside the housing means.
2. A drawer device according to claim 1 , wherein said sensing means senses whether or not said drawer member is drawn out for the predetermined amount during a predetermined period.
3. A drawer device according to claim 1 , wherein said torque limiter slips when the torque exceeds a predetermined limit so that the driving means does not move the drawer member.
4. A drawer device according to claim 1 , wherein said drawer member is curved to project outwardly in a middle portion thereof when the drawer member is located outside the housing means in the open position.
