## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a Continuation of International patent application PCT/2014/043249, filed Jun. 19, 2014, which claims priority to U.S. Provisional patent application 61/836,755, filed Jun. 19, 2013, the disclosures of which are hereby incorporated by reference in their entirety.


FIELD OF THE DISCLOSURE
The present disclosure relates to a slideable locking tool connector.
BACKGROUND
Tools such as screwdrivers, drills and socket wrenches have traditionally provided a mounting means to replace or swap out a shaft or a shaft with a tool on a remote end (i.e., a screwdriver or hex wrench).
Pressure fits, locking collars and moving ball bearings have all been used to hold or latch a shaft to a handle or device.
SUMMARY
Disclosed herein is a connection system, method and device whereby a sliding cylindrical sleeve or collar having an elongated guide or channel fluidly connecting the outer annular wall with the inner annular wall of the sleeve fits over a connector having at least one open end and an elongated slot with a floor and a pin guide through the floor. The pin guide is open to the inside of the connector. Between the sleeve and the slot is a pin having a pin head visible through the elongated guide and two opposing soring arms of a size and shape to fit in said slot and a pin body which movable fits in side pin guide. Sliding the sleeve along the connector connects or disconnects a tool via a retention fixture. The pin body is urged downward into the retention fixture when the sleeve compresses one or more of the spring arms. Sliding the sleeve in an opposite direction decompresses the spring arms and the pin body will move upward back into the pin guide.
According to aspects of one or more exemplary implementations, disclosed is a locking tool-mounting connector, with at least a connector having an open end, a slot, and a pin guide extending into the open end; a slideable sleeve having pin catch guide; a movable pin, having a pin head, curved spring arms extending therefrom, said spring arms being opposite one another on the pin; and a pin body. In some instances, the spring arms are asymmetrical, with one arm above the other arm. In some instances, the pin body also has a curved distal end.
According to aspects of one or more exemplary implementations, disclosed is a locking tool-mounting connector having an elongated connector with an open end forming a tool guide, a slot and a pin guide extending into the open end; a slideable sleeve having pin catch guide; a movable pin assembly having a pin head, a first curved spring arm and a second curved spring arm extending therefrom, a pin body having a distal end; and, wherein the arms are asymmetrical, with one arm above the other arm. In some instances, the pin catch is ovoid with a fluidly connected first catch region and second catch region. In some instances, a lock latch may be interposed between the two fluidly connected regions.
According to aspects of one or more exemplary implementations, disclosed is a locking tool-mounting connector having an elongated connector with an open end forming a tool guide, a slot and a pin guide extending into the open end; a slideable sleeve having pin catch guide; a movable pin assembly having a pin head, a first curved spring arm and a second curved spring arm extending therefrom, a pin body having a distal end; wherein the arms are asymmetrical, with one arm above the other arm and the pin body sits movably in the pin guide. In some instances, the connector includes a tool shaft with retention fixture inserted into the tool guide.
In the above exemplarys the pin head can act as a catch extended above the spring arms and is of a size and shape to pass through the lock latch by temporarily displacing it, whereby sleeve movement is restricted; the distal end of the pin may be curved.
According to aspects of one or more exemplary implementations, disclosed are methods of reversibly affixing a shaft to a connector by placing a pin of a pin assembly in a guide within an elongated connector; then sliding a sleeve having pin catch guide over the pin assembly and the elongated connector whereby the pin head is visible through the pin catch; then inserting a tool shaft with a retention fixture into the open end of the elongated connector; and, moving the sleeve along the connector, whereby the slideable sleeve compresses the two spring arms of the pin assembly and urges the distal end of the pin through the guide into the retention fixture. In some instances, the pin catch is ovoid having a fluidly connected first catch region and second catch region.
According to aspects of one or more exemplary implementations, disclosed are methods of reversibly affixing a shaft to a connector by placing a pin of a pin assembly in a guide within an elongated connector; then sliding a sleeve having pin catch guide over the pin assembly and the elongated connector whereby the pin head is visible through the pin catch; then inserting a tool shaft with a retention fixture into the open end of the elongated connector; and, moving the sleeve along the connector, whereby the slideable sleeve compresses the two spring arms of the pin assembly and urges the distal end of the pin through the guide into the retention fixture. In some instances, the pin catch further comprises a lock latch in between the first catch region and the second catch region. In some instances, the pin head is a catch which extends into the pin catch and is a size and shape to pass through the lock latch by temporarily displacing it.
According to aspects of one or more exemplary implementations, disclosed are methods of reversibly affixing a shaft to a connector by placing a pin of a pin assembly in a guide within an elongated connector; then sliding a sleeve having pin catch guide over the pin assembly and the elongated connector whereby the pin head is visible through the pin catch; then inserting a tool shaft with a retention fixture into the open end of the elongated connector; and, moving the sleeve along the connector whereby the slideable sleeve compresses the two spring arms formed opposite one another on the pin body of the pin assembly and urges the distal end of the pin through the guide into the retention fixture.
In the above exemplars the spring arms may be asymmetrical and the one spring arm nearer to the pin head, when compressed, will urge the distal end of the pin into the retention fixture. The other spring arm whereby the spring arm further from the pin head, when compressed, will not urge the distal end of the pin into the retention fixture.

DETAILED DESCRIPTION
While the specification concludes with claims defining the features of the present disclosure that are regarded as novel, it is believed that the present disclosure's teachings will be better understood from a consideration of the following description in conjunction with the appendices, figures, in which like reference numerals are carried forward. All descriptions and callouts in the Figures are hereby incorporated by this reference as if fully set forth herein.
According to one or more exemplary implementations, as shown in FIGS. 1-5B, a device 10, which may be hand held, provides a platform for one or more sliding tool lock mounting devices, methods, systems and aspects thereof.
An elongated connector 20 (also referred to an arm or leg) has a closed end 22 and an open end 24. Formed axially on the connector is a slot 25 and within the slot is a pin guide 27. A latching spring assembly 30, with opposing first and second spring arms 32 and 34 and a pin body 36, is fitted into the slot. The pin body 36 sits in the pin guide 27 wherein it may move up and down, including extending into the open tool guide 26, the tool guide and pin guide being fluidly connected to the open end 24. The spring arms rest in the slot 25. The spring arms may be asymmetrical whereby the first spring arm 32 is further from the pin body 36 then the distal end of the pin 37 then the second spring arm 34. The distal end of the pin 37 may be curved. In other instances, the spring arms may be symmetrical. At the proximal end of the pin is a locking pin head 38 that extends above the spring arms and can act as a catch. The distal end of the pin 37 may be curved (concave) to facilitate entry and removal from a retention fixture 100 such as that formed in a tool shaft 102 which may support a tool 104.
The first spring arm 32 further comprises a curved member 200 affixed by its proximal end 201 to the pin, whereby the distal end 202 is unattached or free and below the proximal end and near to the distal end of the pin 37. The second spring arm 34 further comprises a curved member 210 affixed by its proximal end 211 to the pin whereby the distal end 212 is unattached or free and below the proximal end and near to the distal end of the pin 37. Both distal ends of the spring arms rest against the floor 28 of the slot 25. In a hand held tool, the connector is attached to a tool body 300, which may be a fixed tool or a torque limiting device within the body. The body may have handles 301 affixed to or formed as part thereof.
A slideable open cylindrical sleeve 50 with an internal annular wall 52 and an external annular wall 54 and at rim 55 at each end is shown. An elongated opening fluidly connects the external annular wall 54 and the internal annular wall 52 thereby forming a pin catch guide 60, which may be locking. At the first end 62 of the locking catch guide is a region larger than the pin head 38 wherein the pin head can move freely. At the second end 64 is a region larger than the pin head whereby the pin head can move freely. Between the first and second ends is a lock latch 65, which is an extension of the sleeve into the elongated opening, thereby pinching it off or otherwise forming a small narrow region, which has a smaller diameter as the pin head 38. For the pin head to be caught into a first catch region 66 or a second catch region 68, the pin head must temporarily displace the lock latch 65, which is a material thin enough and flexible enough to be displaced by said pin head 68. The catching of the pin head 38 in the first region or second region via the lock latch restricts free movement of the sleeve. A force must be applied to the sleeve to displace the lock latch and push it past the pin head, the first catch region 66 and the second catch region 68 are fluidly connected with the lock latch creating a reduced diameter passageway.
The proximal end 201 of the first spring arm is closer to the pin head 38 than the proximal end 211 of the second spring arm. The offset arrangement provides asymmetry to the locking features herein by having the compression of the higher spring arm (closer to the pin head) correspond to extending the pin body 36 further into the open tool guide 26. The asymmetry of the arms within the elongated pin catch guide 60 provides for movement of the sleeve in one direction to be locking, and movement in another direction to be releasing. The arms within the slot 25 hold the asymmetry in one orientation and prevent rotation.
As shown in FIGS. 3A, 3B and 5A when the pin head 38 is in the second catch region 68, the second spring arm 34 is compressed from its proximal end 211 and a less than maximum displacement of the pin body 36 is achieved, thereby the pin body 36 is not extended into the open tool guide 26.
As shown in FIGS. 3A, 5A and 5B when the pin head 38 is in the first catch region 66, the first spring arm 32 is compressed from its proximal end 201 and the maximum displacement of the pin body 36 is achieved, thereby extending it into the open tool guide 26, whereby it is mated with a retention fixture 100.
Methods of locking and unlocking a pin body 36 into the retention fixture 100 are disclosed herein. A pin 30 is placed in slot 25 in a connector 20. The pin body fits into a pin guide 27 and a slideable sleeve is slipped on to the connector and over the pin head 38, whereby the pin head 38 extends through the pin catch guide 60.
In a first position, the slideable sleeve is moved along the pathway of arrow 1000 and the pin head 38 displaces the lock latch 65 and rests in the first catch region 66 and the pin body 36 extends into the open tool guide 26. The internal annular wall of the sleeve 52 applies a force to the first spring arm 32 from the proximal end 201 downward and the distal end 202 is unable to move downward against the floor 28 of the slot 25. The sleeve movement over the arm provides sufficient force to compress the spring arm (allowing movement of the pin body). When a tool shaft 102 with retention fixture 100 is aligned with the open tool guide, the pin body 36 so displaced extends into the retention fixture 100, thereby fixing the tool shaft in place.
To remove a tool shaft affixed by the method disclosed herein, the sleeve 50 is slid along the direction of arrow 1002 and the pin head 38 again displaces the lock latch 65 and now rests in the second catch region 68. The movement places the first spring arm in the open lock latch 65, thereby allowing it to decompress and causing the pin body 36 to withdraw into the open tool guide 26; the second spring arm 34 also decompresses; and the pin body 36 is no longer displaced into the open tool guide 26 nor extended into a retention fixture 100. Accordingly, the tool can be removed.
FIG. 6 shows another exemplar wherein an additional or alternative sleeve fixture 300 is illustrated. The sleeve fixture is an extended region or regions which are formed on the internal annular wall 52 and can fit into a sleeve latch 302 formed as an annular groove on the connector. In some instances, this combination of fixture 300 and latch 302 may be an additional fixing means, in other instances it may be used in lieu of the lock latch 65.
