       [0001]    This application is a Continuation of International patent application PCT/2014/043254, filed Jun. 19, 2014, which claims priority to U.S. Provisional patent application 61/836,755, filed Jun. 19, 2013, and U.S. Provisional patent application 61/862,905, filed Aug. 6, 2013, the disclosures of which are hereby incorporated by reference in their entirety. 
     
    
     FIELD OF THE DISCLOSURE 
       [0002]    The present disclosure relates to a moving locking tool connector. 
       BACKGROUND 
       [0003]    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). 
         [0004]    Pressure fits, locking collars and moving ball bearings have all been used to hold or latch a shaft to a handle or device. 
         [0005]    Rotating collars and pressure locks such as a chuck on a drill are well know in the art; barrel locks have been historically used on hand drills whereby a fixed pin is held by a collar channel.

     DETAILED DESCRIPTION 
       [0024]    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&#39;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. 
         [0025]    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. 
         [0026]    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 pin 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 . 
         [0027]    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 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 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. 
         [0028]    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 the first catch region  66  or the second catch region  68 , it must temporarily displace the lock latch  65 , which is a material thin enough and flexible enough to be displaced by said pin head  68 . 
         [0029]    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. 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. 
         [0030]    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 . 
         [0031]    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 . 
         [0032]    Methods of locking and unlocking a pin body  36  into the retention fixture  100  are disclosed herein. A pin assembly  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 . 
         [0033]    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. 
         [0034]    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. 
         [0035]      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 . 
         [0036]      FIG. 7  shows an assembled view of a hand tool with a twist lock mount. 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.  FIG. 8  is an assembly view of the pin assembly  30 , elongated connector  20  and open cylindrical sleeve  500 . Formed axially on the connector is a slot  25  and within the slot is a pin guide  27 . A latching spring pin 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 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  which acts as a guide that extends above the external annular wall  54  of the cylindrical sleeve  500  that extends above the spring arms and can act as a catch. 
         [0037]      FIGS. 9A-10B  show assembly and lock—unlock views of a moving connector in both plan view and cut-away. A moving open cylindrical sleeve  500  with an internal annular wall  52  and an external annular wall  54  and at rim  55  at each end is shown. A latching spring pin assembly  30  can be seen partially through a “L” shaped opening  600  that fluidly connects the external annular wall  54  and the internal annular wall  52  thereby forming a pin catch guide. The “L” shaped opening  600  forms a first catch region  602  and a second catch region  604 . When the pin head is in the first catch region  602  it is fixed relative to the connector  20 . The pin head  38  is of a size and shape to guide movement of the L shaped opening  600  along the connector  20  between the first region  602 , the second region  604  and the corner  605  of the “L” shaped opening. It is in the unlocked position (See  FIGS. 9A and 9B ). When the pin head is in the second catch region  604  it is in the locked position (See  FIGS. 10A and 10B ). 
         [0038]    When the pin head  38  is in the 2nd catch region  604  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 . When the pin head  38  is in the first catch region  602  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 . 
         [0039]    Methods of locking and unlocking a pin body  36  into the retention fixture  100  are disclosed herein. A pin assembly  30  is placed in slot  25  in a connector  20 . The pin body fits into a pin guide  27  and a movable sleeve is slipped on to the connector and over the pin head  38 , whereby the pin head  38  extends through the pin catch guide  600 . 
         [0040]      FIG. 10A  shows a sequence of positions of the pin head  38  in the “L” shaped opening  600 . At position one  701  the pin head is in the first region  602  of the in a first position “L” shaped opening. At position two  702  the movable sleeve  500  has been slid along the line of arrow  1050  (axial to the connector) and the pin body  36  is extended into the tool guide  26 . 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. After twisting or rotating the sleeve along the line of arrow  1100  the pin head is moved to position three  703 . To remove a tool shaft affixed by the method disclosed herein, the sleeve  500  is moved from position three to position two and then slid to position one ( 701 ). The movement places the first spring arm in the corner  605  of the “L” shaped opening and then back to the first catch region ( 602 ), thereby allowing the spring 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. 
         [0041]    While the method and apparatus have been described in terms of what are presently considered to be the most practical and preferred implementations, it is to be understood that the disclosure need not be limited to the disclosed implementations. It is intended to cover various modifications and similar arrangements included within the spirit and scope of the claims, the scope of which should be accorded the broadest interpretation so as to encompass all such modifications and similar structures. The present disclosure includes any and all implementations of the following claims. 
         [0042]    It should also be understood that a variety of changes may be made without departing from the essence of the disclosure.

         [0044]    Particularly, it should be understood that as the disclosure relates to elements of the disclosure, the words for each element may be expressed by equivalent apparatus terms or method terms—even if only the function or result is the same. 
         [0045]    Such equivalent, broader, or even more generic terms should be considered to be encompassed in the description of each element or action. Such terms can be substituted where desired to make explicit the implicitly broad coverage to which this disclosure is entitled. 
         [0046]    It should be understood that all actions may be expressed as a means for taking that action or as an element which causes that action. 
         [0047]    Similarly, each physical element disclosed should be understood to encompass a disclosure of the action which that physical element facilitates.
