- the blocking pin is in a left position and allows left human hand exercise; shows schematically steps of a swapping process from right hand use (a) to left hand use (d) with intermediate steps (b,c); and shows schematically a base element of the device according to Fig. 1 attached to an arm exercising device, the base element being in a position relative to the arm exercising device for an extended wrist (a) and a bent wrist (b).
- Figures 1 to 6 show a preferred embodiment of the hand motion exercising device 1 according to the present invention, presented from different perspectives and in different actuation positions, i.e. either in open position (cf. Figs. 1, 3, 5) or in close position (cf. Figs. 2, 4, 6).
- open position is to be understood as a position in which the human hand is stretched out, i.e. the metacarpophalangeal and proximal interphalangeal joints of fingers and thumb are stretched. A palm is then substantially flat and the thumb stretched out in substantially normal or inclined direction to said palm.
- close position is to be understood as a position in which the human hand is contracted or clenched such as to form an almost fist-like hand with the fingers, thumb, and hand clenched to bend as far as the exercising device 1 allows for, hence the close position is a kind of a grip position, used, e.g., when grabbing a stick.
- the hand motion exercising device 1 comprises a plate-like, flat base element 11 that has, from top view (cf. Figs. 3 and 4), a shape like a rhombus.
- top view is to be understood as a view onto a top surface 110 of the base element 1 1. Said top surface 110 faces, during exercise, the human hand, more precisely the side of said hand.
- two thumb movement units i.e. a left thumb movement unit 2a and a right thumb movement unit 2b, are arranged in two opposing corner regions of the diamond-shaped base element 11, said regions being designated as a left corner region 110a with the left thumb movement unit 2a and a right corner region 110b with the right thumb movement unit 2b.
- Each of the thumb movement units 2a, 2b comprises a first joint 20 with a first shaft 21a or 21b with a first shaft axis 22 that is oriented substantially perpendicular or normal to the top surface 110 of the base element 11.
- a thumb rest element 26, attached to said first joint 20, is pivotable about the first joint 20 in a first movement plane.
- the first shaft 21a, 21b protrudes about 1 to 5 centimeters upward beyond the top surface 110. This is to move the first movement plane locally upward with respect to the top surface 110 such that the first movement plane is inclined with respect to the top surface and such that a rotation point of the thumb joint lies within said first movement plane if the human hand is placed properly in the device 1, which avoids harmful shear forces acting on said thumb joint.
- Proper placement of the hand means that the side of the hand including the pinky, is facing down onto the top surface 110, while the palm is substantially perpendicular to the top surface 110.
- the fingers encompass the perpendicularly to said top surface 110 extending finger rest elements 36, 37, while the thumb encompasses the thumb rest element 26 of the respective thumb movement unit 2.
- the first shaft 21a, 21b further comprises a universal joint.
- the first shaft 11 and the universal joint are arranged in a sleeve bushing 27.
- Said sleeve bushing 27 circumferentially encloses the protruding part of said first shaft 1 1 , including the universal joint.
- the sleeve bushing 27 is furthermore fixedly connected, at its proximal end, to the base element 11.
- the bushing 27 accommodates the first shaft with the universal joint and protects the human hand from moving parts, in particular so during exercising.
- a distal free end of the universal joint is rotatably accommodated in the tapered distal end region of the bushing 27, where an opening 272 is arranged (cf. Fig.
- Said opening 272 at the distal end of the bushing 27 faces in a predefined direction, wherein said direction includes an angle with respect to the first shaft axis 22 ranging from 60 to 85 degrees and being preferably about 70 degrees. Accordingly, an angle between the top surface 110 and the first movement plane is 5 to 30 degrees, preferably 20 degrees.
- Said distal free end of the universal joint is further provided with a distal recess 28 for positive-fit interlock with the therein removably attached thumb rest element 26. The recess 28 is accessible through the opening 272. Consequently, the sleeve bushing 27 defines, with its distal free end, in particular with its opening 272, the first movement plane of the first joint 20 of the thumb movement unit 2.
- said universal joint guides the movement of the first shaft 21a, 21b about the first shaft axis 22 into the first movement plane being inclined with respect to the top surface 110 by about 5 to 30 degrees, preferably about 20 degrees, toward a second shaft 31 of the finger movement unit 3, the second shaft 31 being arranged on said base element 11.
- the first joint 20 defines the first movement plane, the latter being skewed with respect to the top surface 110 toward the second shaft 31 , while the thumb rest element 26 is pivotable in said first movement plane about the first joint 20 for the purpose of guiding the thumb to be exercised under force loading in a natural grip movement.
- Figs. 5 and 6 Said inclination of the first movement plane with respect to the top surface 110 may be seen best in Figs. 5 and 6. From these figures the position of the thumb rest element 26 may be seen in open position (Fig. 5) and in close position (Fig. 6). It becomes clear that a thumb of the human hand, resting on said thumb rest element 26, moves on its way from the open position to the close position in a rotation movement about the first joint 20 downward in the inclined first movement plane toward the top surface 110 and said second shaft 31, i.e. toward the fingers resting on the finger rest elements 36, 37.
- a wrist of said hand remains substantially unmoved such that the movement is a substantially isolated hand motion exercising movement.
- the thumb movement is moreover preferably such that the first movement plane is substantially parallel to a plane through an oblique arch spanned by the thumb and one finger, preferably the ring finger, and the movement such that said oblique arch is partially collapsed in the positive movement (from open position to close position).

- This coupling via gear train 7 is in summary designed such that between the first shafts 21a, 21b there are three transmission wheels 75, 76, 77, while between the first shafts 21a, 21b and the second shaft 31, there are two transmission wheels 75, 77 or 76, 77.
- the second mechanical motion linkage 38 is described with reference to Figures 13 and 14.
- the second mechanical motion linkage 38 is provided within the bridging element 39. This is advantageous, like providing the first mechanical motion linkage 4 within the base element 11, as the moving parts are hidden away from the user, thereby decreasing the risk of injury and the risk of jamming the mechanics with foreign objects.

- first and right first shafts 21a, 21b are coupled by a third mechanical motion linkage 29, being constructed like the second mechanical motion linkage 38 or by a simple stiff rod, wherein a first drive motor 8 drives, preferably via the third mechanical motion linkage 29, the second shaft 31 and a second, separate drive engine 81 drives the first shafts 21a, 21b.
- the coupling between the first and the second shafts 21a, 21b, 31 may then be achieved by control electronics controlling said drive motors 8, 81.
- the other elements of this embodiment e.g. like the movement units or the second mechanical motion linkage 38 are constructed as described herein.
- the safety unit 5 is described with reference to Figures 15 and 16.
- the hand motion exercising device 1 preferably comprises a safety unit 5 having a switching device 51.
- Said safety unit 5 includes a switching pin 52 by means of which the hand motion exercising device 1 is switchable for left or for right human hand exercise.
- Said switching pin 52 is pluggable into the hand motion device 1 with a guide tube or the like (not shown in Fig. 15 and 16) allows moving the pin 52 in the direction of its longitudinal axis.
- the switching pin 52 interacts, with its front part, with a blocking pin 53 that protrudes through an oblong slit 54 of the bridging element 39.
- Figure 15 shows the position of a switching pin 52 in a first securing position, while Fig.
- Blocking pin 53 can be moved in the oblong slit 54 in a sliding movement to provide an abutment for securing a maximum pivot angle a max of the finger movement unit 3 such that the fingers are not overstretched either for a right hand or a left hand configuration of the device 1, 10.
- the blocking pin 53 is secured by the switching pin 52 in a right position.
- the blocking pin 53 is secured by the switching pin 52 in a left position in the transversal through slit 54.
- Figure 17 shows a sequence of situations (a) to (d) as they arise if one swaps the hand motion exercising device 1 from right hand use to left hand use.
- Figure 17(a) shows the hand motion exercising 1, i.e. the base element 1 1 with the attached bridging element 39 from below and in a position ready for right hand use (like in Fig. 16): the switching pin 52 is in locked position, the blocking pin 53 safely caged in a right half of oblong slit 54 in Fig. 17(a) by the switching pin 52, preferably with a spring reset acting on the switching pin 52.
- the device 1 is in extended finger position.
- the blocking pin 53 acts such as to allow a swivel movement of the bridging element 11 from the situation according to Fig.
- Figure 17(b) shows a first intermediate step during swapping the device 1 from right to left hand use.
- the switching pin 52 is unlocked, the blocking pin 53 therefore free to move along and in the oblong slit 54.
- Figure 17(c) shows a further intermediated step, wherein the switching pin 52 is unlocked and the bridging element 39 is rotated to the left of Fig. 17(c) such that the blocking pin 53 is left of the switching pin 52 in Fig. 17(c).
- Figure 17(d) shows the device 1 ready for left hand use, the device 1 being in extended finger position. After moving the switching pin 52 from the situation in Fig. 17(c) into locking position (like in Fig. 17(a)), the bridging element 39 is rotated back to the right of Fig. 17(d) to extend in distal direction like in Fig. 17(a). When the bridging element 39 is moving to the right of Fig.
- the blocking pin 53 is eventually contacting the switching pin 52, whereafter any further movement of the blocking pin 53 to the right of Fig. 17(d) is blocked. Therefore, the blocking pin 53 is moved relative to the bridging element 39 in the oblong slit 54 to the left of Fig 17(d); hence, the blocking pin 53 moves from the right half in the left half of slit 54 (as seen from below). After that, the blocking pin 53 is caged in the left half of the oblong slit 54, by the switching pin 52, preferably with a spring reset acting on the switching pin 52.
- the safety unit 5 thus provides the opposite abutment to the mechanical stop provided by the finger and thumb rests 26, 36.
- the blocking pin 53 blocks then almost half the pivot angle (it blocks out either the left or the right side movement), but allows for full stretch of the fingers due to the sliding.
- the switching pin 52 is mounted below the second mechanical linkage 38 and stays in place.
- the bridging element 39 is blocked from pivoting. LIST OF REFERENCE SIGNS
