Description

CLOSURE OF RATCHETS BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of bolt structures. 2. Brief Description of the Prior Art Locking structures are used in many applications to secure items such as panels from each other. For example, containers, cabinets, closets, compartments and the like can be fastened with a bolt. An important use for locks is in the automotive field, where there is desire and need for automotive access compartments, such as for example the trunk or passenger compartments of vehicles, as well as interior compartments such as the glove box. Various locks for panels have been employed where one of the panels such as a swinging or similar door is to be fastened to a stationary compartment or panel body. Prior art devices generally use a locking member that is externally spring loaded by one or more torsion springs that are provided separately. For example, some devices of the prior art are based on an insurance comprising rigid metal parts and require additional bypass members for operation of the structure. COMPENDIUM OF THE INVENTION The present invention relates to a bolt system for fastening two joined panels such as those of storage structures where an enclosure is held by a door or panel that will remain in a closed position until released. An example of use of the present bolt system is in connection with automobile glove boxes or other compartments that are to be fastened for storage of goods there. The present invention provides a novel ratchet bolt structure with a spring locking member, which provides the locking member with its own internal spring force, when the locking member is deflected by an actuating lever. The actuating lever may be provided in the form of a handle or vane. The spring locking member allows a force of a handle of the bolt structure to be transmitted to a pawl that selectively engages and detaches a latch member. When the catch member engages the pawl, the pawl is rotated until the locking member slides behind it. The pawl is provided with a torsional spring member which causes a force load from the spring member to be supplied to ratchet. When the blade is rotated or moved oscillating away from the panel surface to which it is connected, the spring locking member engages and lowers and retracts out of the ratchet path. The pawl detaches from the pawl with the actuation of the palette, which causes the spring-locking member to release from its engagement with the pawl, thereby causing the spring member of the pawl to provide a force load to the pawl, and releases its force load to return the ratchet to its released position away from engagement with the sear. The fastener wire is thus released and the paddle or handle is reinitialized with a spring loaded mechanism to its original position. The present invention also provides an interlocking mechanism wherein a key can interlock or secure and release the ratchet structure. In addition, the present invention also provides a means whereby the handle or vane can be displaced from the locking and ratchet member. This offers greater flexibility to select a location for the ratchet and for greater alternate placements when this bolt is used as described herein.

A main objective of the present invention is to provide a novel ratchet structure that selectively engages with a detent member and includes a spring locking member that is spring loaded with its own spring force, for coupling and releasing a ratchet of a securing member, when a handle is actuated. Another object of the present invention is to provide an interlocking member that is constituted by plastic or spring steel. Another object of the present invention is to provide a lock that can be operated by a key or other operator, such as radio, infrared, electronic or other means, which selectively couples the locking member against movement.
