BRIEF SUMMARY
DESCRIPTION
1. Technical Field
This invention relates to a vehicle-mounted storage apparatus equipped with a safety device which operates when an abrupt inertia force particularly due to vehicle crushing is applied, such that any object can be prevented from projecting into the compartment of the vehicle.
2. Background Art
Conventionally, it has been known such type of storage apparatus which comprises a housing having an opening, a projecting object being held in the housing movably in the projecting direction from the opening, a forcing means for forcing the projecting object in the projecting direction from the opening of the housing, a lock device for locking the projecting object in the non-projecting position against the force of the forcing means and for unlocking the projecting object at the non-projecting position when the projecting object is further pressed toward the housing, and a safety device for stopping the unlocking operation of the lock device when an inertia force is applied (see e.g. Japanese Patent Laid-Open No. Sho 64-41434).
The above-mentioned conventional lock device is composed of a cam groove having a heart-shaped island as the center and formed in either one of the housing or the projecting object, a lock pin axially supported in residual one of the housing or projecting object, and a pressing means for pressing the lock pin toward the bottom of the cam groove.
The above-mentioned conventional cam groove is composed of an introductory path extending toward a tapering portion of the heart-shaped island, an outward path extending along one side of the heart-shaped island with a depth gradually shallowing from the introductory path, a doubled portion extending from the outward path to deeper than the shallowest end of the outward path and having a closed end, a stopping portion disposed in vicinity of the doubled portion along a constricted portion of the heart-shape formed at the center of the other end portion of the heart-shaped island and formed to be deeper than the doubled portion, an escape portion closed and formed in vicinity of the stopping portion and extending toward the other side of the heart-shaped island with a depth deeper than that of the stopping portion, and a returning path extending along the other side of the heart-shaped island with a depth gradually becoming shallower than that of the escape portion to be communicated with the introductory path and having the shallowest end higher than the bottom of the introductory path.
In the conventional storage apparatus, however, there have disadvantages that the lock pin would undesirably become bent or the outer periphery wall of the cam groove would be broken off, due to the hard collision of the lock pin with the outer periphery wall of the cam groove when an abrupt inertia force is applied.
It is therefore an object of this invention to provide a vehicle-mounted storage apparatus equipped with a safety device, which is capable of preventing the lock pin and the cam groove from damaged by forming a tapered surface on the outer periphery wall of the cam groove such that the lock pin is popped up by the tapered surface of the cam groove when the inertia force is applied.
It is therefore another object of this invention to provide a vehicle-mounted storage apparatus equipped with a safety device, which is capable of preventing the unlocking of the popped-up lock pin having been in locked state caused by moving to the escape portion by forming a guide groove having one end opened toward the doubled portion and the other end to be closed such that the popped-up lock pin returns to the returning portion located just before the stopping portion.
DISCLOSURE OF THE INVENTION
In the present invention, a tapered surface inclined toward the bottom of a stopping portion of a cam groove is formed at a projecting portion projecting toward a heart-shape constricted portion of a heart-shaped island in the cam groove of a lock device.
According to this invention, therefore, the distal end of the lock pin, in the locked state o
