Patent Application
20230417078
The present disclosure relates to a multicomponent tool, and more particularly it relates to a folding lock pick set which facilitates efficient storage and a release mechanism for the tension wrench.
When a lock needs to be picked one requires two tools including a lock pick and a tension wrench. One of the more common kinds of lock picks for the pin-tumbler type of lock is a small flat tool with one or more projections thereon. The tension wrench or tool is also to be used with this lock pick, where the tension wrench is used to turn the keyway, or exert a turning force on the keyway in the lock. The pick is inserted into the lock and moved forwardly and backwardly along the keyway pushing the pins up. By careful manipulation with the lock pick and tension wrench, the pins will align themselves to the open position and the lock opens. While a lock pick folder is not new the conventional once all have very awkward ways of storing the tension wrench.
It would be very advantageous to provide a lock pick folder that provides a better locking and release mechanism for the tension wrench.
The present disclosure discloses a folding lock pick set having a set of lock picks pivotally mounted in the housing at their proximal ends, a locking bar pivotally mounted at its proximal end which is adjacent to the pivotally mounted proximal ends of the lock picks. An L-shaped tension wrench is stored inside the locking bar. The tension wrench is released by the depressing locking bar so that the back end of the shorter section of the tension wrench lowers past the fame of the housing and this allows for the tension wrench to slide out the distal end of the housing. When the locking mechanism/bar is not depressed the tension wrench sits securely inside the housing. The proximal end of the locking bar includes a pawl which engages two (2) cut-outs in the proximal ends of the lock picks, one cut-out being engaged by the pawl when the picks are stored in the housing to prevent them rotating out of the housing, and the other being engaged by the pawl when a given lock pick is rotated out of the housing to prevent it from rotating while the lock operation is ongoing.
The present disclosure provides a multicomponent tool, comprising a housing and a first tool pivotally mounted at its proximal end in the housing; a lock bar pivotally attached at its proximal end in the housing that when unlocked allows the first tool to pivot in and out of the housing. The lock bar includes a storage location therein and at least a second tool is stored in the storage location which upon the lock bar being engage to allow pivoting of the first tool out of the housing, a portion of a second tool is forced out of the housing to be grasped and removed from the lock bar.
the mechanism coupled to said lock bar for biasing said lock bar back to its locked position once released may be a spring located between the distal end of the lock bar and a center stop on the interior of the housing such that upon releasing the distal end of the lock bar the spring biases the lock bar back to a locked position in which the first and second tools are locked inside the housing.
In a non-limiting example, the present disclosure provides a folding lock pick set which comprises:
The proximal end of the lock bar may have a pawl configured to engage the opposed cut-outs, and includes a biasing mechanism coupled to the lock bar for biasing the lock bar back to its locked position once released. A distal end of the housing has an opening, wherein upon depressing a distal end of the lock bar an end of the shorter section of the L-shaped tension wrench is pushed through the opening wherein it can slide out of said housing. Upon depressing the distal end of the lock bar disengages the pawl from a first of the two opposed cut-outs allowing for rotation of a selected lock pick out of the housing substantially 180 degrees with respect to the housing, and releasing said lock bar causes the pawl to engage the second cut-out to lock the pick in the open position.
The housing may include a center stop bolted on an interior of the housing that acts as a stop for the locking bar when it is being depressed.
The mechanism coupled to the lock bar for biasing the lock bar back to its locked position once released may be a spring located between the distal end of the lock bar and the center stop on the interior of the housing such that upon releasing the distal end of the lock bar the spring biases the lock bar back to a lock position in which the lock pics and the L-shaped tension wrench are locked inside the housing.

The present disclosure provides a multicomponent tool, comprising a housing and a first tool pivotally mounted at its proximal end in the housing; a lock bar pivotally attached at its proximal end in the housing that when unlocked allows the first tool to pivot in and out of the housing. The lock bar includes a storage location therein and at least a second tool is stored in the storage location which upon the lock bar being engage to allow pivoting of the first tool out of the housing, a portion of a second tool is forced out of the housing to be grasped and removed from the lock bar. The tool may be a folding knife or other folding multicomponent tools, screw drivers etc. to mention some non-limiting examples which employ a lock bar for locking the tool(s) when deployed out of the housing and locking them inside the housing when not in use.
Referring to
Included is a mechanism coupled to the lock bar for biasing the lock bar back to its locked position once lock bar 12 is released. In a non-limiting embodiment, the mechanism is a spring (not shown) located between the distal end of the lock bar 12 and the center stop 48 on the interior of the housing 10 such that upon releasing the distal end of the lock bar 12 the spring biases the lock bar 12 back to a lock position in which the lock pics 20 and the L-shaped tension wrench 17 are locked inside the housing 10.
In operation, when it is required to be used, the operator first removes the tension wrench 16. This is accomplished by depressing the locking bar 12 at the location of the cutout 60 in housing 10 (see
The single locking bar 12 not only locks the tools (lock picks) into place when in use it also securely holds the tension wrench in way that stills allows for easy accessibility. The lock picks 20 have two (2) cutouts 78 at their proximal ends adjacent to the pivot point 32 and the end of the locking bar 12 has a pawl 80. When the locking bar 12 is depressed the pawl 80 lifts out of the cutout allowing the picks to rotated open. Once fully open the locking bar 12 is released and the pawl 80 lowers into a cutout 78 locking the picks 20 in the open position. The tail end 70 (see
When lock bar 12 is fully depressed by the user, the shorter side of the L-shaped tension wrench 16 is pushed down so the end of the shorter section of the tension wrench 16 is forced below the housing and can be grasped by the user and pulled out. When the locking bar 12 is not depressed the tension wrench 16 sits above this opening and sits entirely in housing 10 so it cannot slide out. Put another way, access the wrench 16 is provided by the user depressing the bar 12 and when the locking bar is depressed with a finger until the tension bar has lowered to the opening in the tail cap. The housing 10 can then be turned to let the tension wrench 16 slide out by gravity. By the operator removing their finger from the locking bar 12 it will move back to its original position. Once the tension wrench 16 is removed, the user grasps the desired pick and rotates it about pivot 32 until it is fully out of housing 10 and collinear with housing 10 at 180 degrees.
Once the operator is finished picking the lock, the reverse procedure is followed, first the pick(s) are pivoted back into housing 10 by pressing down the locking bar 12 to lift the pawl 80 letting the picks rotate back to their storage position within housing 10. Once the lock picks 20 are in the storage position with the locking bar 12 still depressed the wrench 16 can also be slid into the it's storage position within slot 38 within the locking bar 12. Once the lock picks and tension wrench are in the storage position the locking bar 12 is then released so that the pawl 80 engages with one of the cutouts 78 of each pick 20 which locks the picks 20 in the stored position, with the tension wrench 16 securely drawn within the housing 10.
Typically, the present lock pick set will contain several different lock picks and the user selects the one they want and rotates it out of housing 10 and locked in the open position while the rest are locked in the housing 10. Also, while this is a folding lock pick and tension wrench but the concept of storing a tool in a locking bar is unique and the other tools besides tension wrenches may be used. For example the present device may be other than lock picks, for example storing tools in the lock bar may be adapted for other devices where multi-tool components are present, such as but not limited to knives and other multi tools.
