Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to pull handles for gym training apparatus. In particular this invention relates to device and method for a pulling devise which may allow the angle between the pull handles to be adjusted. 
       BACKGROUND OF THE INVENTION 
       [0002]    Usually handles for pulling training apparatuses exist with fixed angles and the user can choose from the variety of handles the handles which the angle between them suites him the best, and to install them on the training apparatus. A user may have difficulties in finding suitable handles in the variety of existing handles, and the process of choosing the best fitting handles may cause waste of time. It is therefore desired to have a device and method providing adjustable handles which enable every user to adjust the angle between them to his comfort, and which cancel the need for several different handles with different angle.

       DETAILED DESCRIPTION OF THE INVENTION 
       [0009]    The method and device of the present invention disclose handles for a weight pulling device which may allow the angle between the pull handles to be adjusted. 
         [0010]    Attention is made to  FIG. 1 , which is a partial schematic illustration of adjustable pull handles device  10  constructed and operating according to some embodiments of the present invention. Device  10  may be pull handles of a pulling training machine (not shown), and it may be connected to pulling training machine by connection unit  30 . Connection unit  30  may be connected to pulling training machine using hole  32 . Device  10  may comprise two handles  12 . Each handle  12  may comprise a cogwheel  14  at one end of it, where the other end of each handle  12  may be used for gripping and pulling by the user. Cogwheels  14  of handles  12  may be engaged together and may be connected to connection unit  30  by pivots  15  which allow cogwheels  14  to rotate freely together about pivots  15 . Device  10  may further comprise two lock/unlock cogged units  16 . The cogs of cogged units  16  may engage with the cogs of cogwheels  14  thus locking cogwheels  14  to their position and preventing them from rotating. When cogwheels  14  are locked a certain angle between the handles  12  may be fixed firmly. Each lock/unlock cogged unit  16  may engage to both of cogwheels  14  at the same time. Each lock/unlock cogged unit  16  may be connected to the connection unit  30  by spring  18 . Springs  18  may keep the cogged units  16  engaged with cogwheels  14  when springs  18  are at equilibrium. Springs  18  may be connected to connection unit  30  at pivots  17 . Lock/unlock cogged units  16  may be limited to move along axis X-X that connects both pivots  17 . Lock/unlock cogged units  16  may be pushed away from cogwheels  14  by pushing dowels  19 . When lock/unlock cogged units  16  are pushed away from cogwheels  14  the cogs of the cogged units  16  may depart from the cogs of cogwheels  14 , which enables cogwheels  14  to rotate freely together, and therefore enables to change the angle between handles  12 . 
         [0011]    Attention is now made to  FIGS. 2A and 2B , which are schematic illustrations of adjustable pull handles device  10  constructed and operating according to some embodiments of the present invention, without its cover. Lock/unlock cogged units  16  can be pushed away from cogwheels  14  by separator unit  20  which may be held between two dowels  19 . Separator unit  20  enables to change the distance between lock/unlock cogged units  16 . Separator unit  20  may be rotated about pivot  21 . In rest position of separator unit  20 , shown in  FIG. 2A , the distance between lock/unlock cogged units  16  may be such that the cogs of lock/unlock cogged units  16  may engage with the cogs of cogwheels  14  thus locking cogwheels  14  to their position and preventing them from rotating. In this position the angle between the handles  12  may be fixed firmly. When rotating separator unit  20  to rotated position, shown in  FIG. 2B , the distance between lock/unlock cogged units  16  may increase, and the cogs of lock/unlock cogged units  16  may depart from the cogs of cogwheels  14 , which enables cogwheels  14  to rotate freely together, and therefore enables to change the angle between handles  12 . Separator unit  20  may comprise barriers that may prevent separator unit  20  from further rotating after reaching certain rotated position which enables cogwheels  14  to rotate freely together. 
         [0012]    Attention is now made to  FIG. 3 , which is a schematic illustration of adjustable pull handles device  10  operating according to some embodiments of the present invention. Releasing means  22  may be connected to the separator unit  20  (not shown) to facilitate the rotation of separator unit  20 . When a change of the angle between handles  12  is required, releasing means  22  may be rotated about pivot  21  (not shown), thus activating separator unit  20  and enabling change of the angle between handles  12 . When rotated back to rest position, that is equilibrium of springs  18 , the angle between the handles  12  may be fixed firmly. 
         [0013]    Attention is made now to  FIG. 4 , which is a schematic flow chart illustrating the operation of device  10  according to some embodiments of the present invention. When a user of a training device wishes to re-adjust the angle between handles  12  he may rotate releasing means  22  (step  42 ). Next step may be the changing of the angle between handles  12  to the desired angle (step  43 ) by rotating handles  12  about pivots  15 . Next, the user may re-lock handles  12  at their new desired angle (step  44 ) simply by rotating releasing means back to rest position. Finally, the user may continue his workout (step  45 ) by pulling handles  12 . Steps  42 - 45  may be repeated any time a change in the angle between handles  12  is required or step  46  may be repeated if workout is desired. 
         [0014]    While certain features of the invention have been illustrated and described herein, many modifications, substitutions, changes, and equivalents will now occur to those of ordinary skill in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention.
