    GRIP STRENGTHENING SUPPORT DEVICE Technical area The present invention concerns a grip strengthening support device having at least one fin-ger portion for enhancing the grip for at least one corresponding finger of a wearer bymeans of at least one artificial tendon arranged along at least one finger portion of the grip strengthening support device.
    Background art There are previously known grip strengthening support devices, for example shown in WO2008/027002. ln this document a finger glove for grip strengthening is shown, having atleast one glove finger with at least one artificial tendon on the inside of the glove finger onboth sides ofthe glove finger and the artificial tendon runs in a duct attached on the insideof the glove finger. When a pulling force is applied to the artificial tendon the glove finger will bend towards the palm ofthe glove, i.e. the ventral side of the glove.
    One problem is the way the at least one artificial tendon moves during pulling of the artifi-cial tendon in relation to the glove and a hand of the wearer. During the pulling of the atleast one artificial tendon the glove finger and a finger positioned inside of it will bend to-wards a ventral side of the glove and into a gripping position. At the transition between theglove finger and glove palm the artificial tendon tend to move inwards the centre of thebent glove finger leaving a space between the artificial tendon and a hand ofa wearer. Thusthe glove will also be moved inwards the centre. Thus the glove may be in the way when gripping, for example. Additionally, it is uncomfortable for the wearer.
    Summary ofthe invention The aim ofthe present invention is to diminish the above problems. According to an aspectof the present invention a grip strengthening support device having at least one finger por-tion for enhancing the grip for at least one corresponding finger of a wearer by means of at Application text 2016-05-30 160018SE least one artificial tendon arranged along at least one finger portion of the grip strengthen-ing support device. The finger portion comprises material at at least along both sides and atip, and possible along a dorsal side, corresponding to a finger of a wearer. The at least oneartificial tendon is attached along both sides of a finger portion so that the artificial tendonmay move in its length direction in respect to the sides of the finger portion. The artificialtendon runs along the side closer to a ventral side than the dorsal side of the finger portion,at least at positions corresponding to joints of a wearer's finger, so that the finger portionwill transfer a force in order to provide a movement ofthe wearer's finger towards a grip-ping position when the at least one artificial tendon is retracted. The artificial tendon runsin a detour towards or to a position in the middle between the dorsal and ventral side orcloser to the dorsal side at a proximal portion of the finger portion. Because of this detour the artificial tendon will run closer to the palm ofthe wearer during gripping.
    According to an embodiment the at least one artificial tendon is attached by means of loopsor at least partly by means oftunnels fixedly arranged at the material, at least in the vicinityof the positions corresponding to joints of a wearer's finger and the detour. Thus the pathofthe artificial tendon may be controlled in an effective way in order to provide the desiredfunction and result. lt is also conceivable that the at least one artificial tendon runs in a full tunnel along the full side of the finger portion.
    According to an embodiment the at least one artificial tendon is attached at the tip of thefinger portion slightly towards the ventral and dorsal side and are running along a thoughtstraight line coming closer to the ventral side when coming closer to the proximal portion of the finger portion, where the detour is positioned, when the finger portion is straight.
    According to an embodiment the finger portion is made up with a material having the atleast one artificial tendon arranged on the outside thereof. Preferably, the finger portion ismade up with a stretchable material having at least one patch of non-stretchable materialarranged on the outside of the stretchable material, where the at least one artificial tendonis arranged at the at least one patch. Both ofthese embodiments may have the at least onefinger portion covered by means of a glove like device.

    Application text 2016-05-30 160018SE 100 105 110 115 120 Detailed description of embodiments ln Fig. 1 it is shown a view of an embodiment of a grip strengthening support device havingat least one finger portion 1 for enhancing the grip for at least one corresponding finger ofa wearer by means of at least one artificial tendon 2 arranged along at least one fingerportion 1 of the grip strengthening support device. The shown finger portion may for exam-ple be suitable for a middle finger of a wearer's hand. The finger portion 1 comprises mate-rial 3 at least along both sides 4 and a tip 5, and possible along a dorsal side 6, correspondingto a finger of a wearer, the at least one artificial tendon 2 is attached along both sides 4 ofa finger portion 1 so that the artificial tendon 2 may move in its length direction in respectto the sides 4 of the finger portion 1. The finger portion 1 may be suitable for any of the fingers of a wearer's hand including the thumb.
    The artificial tendon 2 runs along the side 4 closer to a ventral side 7 than the dorsal side 6ofthe finger portion 1, at least in the vicinity of positions 8a-c corresponding to joints of awearer's finger, so that the finger portion 1 will transfer a force to the wearer's finger inorder to provide a movement of the wearer's finger towards a gripping position, i.e. thefinger moves inwards the palm of the wearer's hand, when the at least one artificial tendon 2 is retracted or pulled by means of an actuator 13. This is shown in Fig. 6.
    The artificial tendon 2 runs in a detour 9 towards or to a position 10 in the middle betweenthe dorsal 6 and ventral 7 side or closer to the dorsal 6 side at a proximal portion 11 of thefinger portion 1. The detour 9 is positioned between two positions 8a and 8b correspondingto the joints of a wearer's finger, where the first position 8a corresponds to the joint at theproximal end ofthe finger at the palm and the second position 8b corresponds to the jointat the other end of that piece of phalangeal bone of the wearer's hand. The position 10 issituated at a thought line 12 dividing the finger portion side 3 in two portions, the dorsal 6 and the ventral 7 portion. ln Fig. 2a a schematic view of different routes for an artificial tendon 2 is shown when afinger of a wearer is straight and in line with a palm of the wearer. For clarity reasons thegrip strengthening support device, such as a glove like device, is not shown. The thought Application text 2016-05-30 160018SE 125 130 135 140 145 150 line 12 goes from the first position 8a corresponding to the joint at the proximal end of thefinger 14 at the palm 15 and the second position 8b corresponding to the joint at the otherend of that piece of phalangeal bone of the wearer's hand. The thought line 12 continuesfurther out to the distal position 8c corresponding to the distal joint of the wearer's finger.The thought line runs along the phalanges of the wearer's finger. The piece of material 16of a finger glove corresponding to the piece of skin present between fingers of a hand is shown in the figure.
    Three paths 17a-c for the artificial tendon 2 is shown schematically. Path 17a shows thepath of the artificial tendon 2 of known grip strengthening devices. Path 17b shows a pathwhere the detour 9 runs towards a position 10 in the middle between the dorsal 6 andventral 7 side, towards the thought line 12. Path 17c shows a path where the detour 9 runs closer to the dorsal 6 side, i.e. crosses the thought line 12.
    Fig. 2b shows the finger 14 of a wearer is bent towards the palm 15 of the wearer, theventral side 7. For clarity reasons the grip strengthening support device, such as a glove likedevice, is not shown. ln this figure it is schematically shown how the different paths 17a-cdiffer during bending. The previously known path 17a strives inwards a thought centre 18of a gripping position. Along the finger portion 1 a counteracting force is applied by meansof at least a portion of a dorsal side 6 of the finger portion 1 holding the artificial tendon 2in place. At the piece of skin 16 between fingers of a hand it is not possible to provide thiscounteracting force leading to the shown space 19 between the palm 15 of the wearer andthe artificial tendon 2. At the outer sides 4 of the index finger and the little finger, respec-tively it is not necessary having a detour as counteracting forces may be applied from the dorsal side 7.
    According to the invention a detour 9 is provided. Two variants of detours are shown aspaths 17b-c in Fig. 2b, which are providing a closer position of the artificial tendon 2 to thepalm 15 of the wearer. Path 17b showing a path where the detour 9 runs towards a position 10 in the middle between the dorsal 6 and ventral 7 side, towards the thought line 12, gives Application text 2016-05-30 160018SE 155 160 165 170 175 180 a closer position of the artificial tendon 2 to the palm 15 ofthe wearer than the previously known path 17a.
    Path 17c showing a path where the detour 9 runs closer to the dorsal 6 side, i.e. crossingthe thought line 12, give an even closer position of the artificial tendon to the palm 15 ofthe wearer than path 17b. On the other hand path 17c might give rise to another effect ofthe artificial tendon 2. lt will strive towards the dorsal side 6 between 8b and 8c. ln this caseit is important to provide a counteractive support on the ventral side 7 of the finger portion 1. lt is thus possible to provide the artificial tendon 2 in a detour 9 in any conceivable path 17towards or to a position 10 in the middle between the dorsal 6 and ventral 7 side or closerto the dorsal 6 side at a proximal portion 11 of the finger portion 1. A top 24 of the detour9 may be positioned as close to the proximal end of the finger portion 1 as possible, i.e. asclose to the skin piece 16 of a wearer's hand when in use, in order to have the closest travel of the at least one artificial tendon 2 towards the palm of a wearer during gripping.
    According to an embodiment shown in Fig. 1 the at least one artificial tendon 2 is attachedat a tip 5 ofthe finger portion 1 close to the middle between the ventral 7 and dorsal 6 sideand are running along a thought straight line coming closer to the ventral 7 side on its path to the detour 9 is positioned. Fig. 1 shows when the finger portion 1 is straight. ln order to provide the desired path 17 for the artificial tendon 2 it may be controlled bymeans of loops 21 through which the artificial tendon 2 travels. This is shown in the exem-plified embodiment in Fig. 3. Preferably, loops 21 are arranged at the material 3 at least inthe vicinity of the positions 8 corresponding to the joints of a wearer's finger and at thedetour 9. ln Fig. 4 it is instead shown tunnels 22 for the artificial tendon 2 to travel through.These tunnels 22 may be short and preferably positioned at the material 3 at least in thevicinity of the positions 8 corresponding to the joints of a wearer's finger, or between the positions 8, and at the detour 9. But it is also conceivable having tunnels 22 running along Application text 2016-05-30 160018SE 185 190 195 200 205 210 215 the full side 3 of the finger portion 1 including the detour 9. The shown finger portion in Fig. 3 and 4 may for example be suitable for a middle finger of a wearer's hand.
    An artificial tendon 2 may run from an actuator 13 via one or several guides 23 (see Fig. 6)towards a finger portion 1 and distally along a first side 4 of the finger portion 1 to the distalend of the finger portion 1, the tip 5, and back proximally along the second side 4 of thefinger portion 1 via one or several guides 23 to the actuator 13. lt also possible to have twoartificial tendons 2 for one finger portion 1 where a first artificial tendon 2 runs from theactuator 13 via one or several guides 23 towards a finger portion 1 and distally along a firstside 4 of the finger portion 1 to the distal end of the finger portion 1, the tip 5, where it isattached, preferably at the first side 4, to a tip portion 5 of the finger portion 1. On theopposite side, the second side 4, a second artificial tendon 2 is attached and it runs along the second side 4 of the finger portion via one or several guides 23 to the actuator 13.
    According to one embodiment the finger portion 1 is made up with a material having the atleast one artificial tendon 2 arranged on the outside thereof. According to a special embod-iment of this, the finger portion 1 is made up with a stretchable material 3' having at leastone patch 25 of non-stretchable material arranged on the outside ofthe stretchable mate- rial 3'. An example ofthis is shown in Fig. 5.
    The at least one artificial tendon 2 is arranged at the at least one patch 25. ln the shownexample a tunnel 22 for the artificial tendon 2 is made up by stitches 26 along an edge 27of the patches 25. Thus the artificial tendon 2 can run in these tunnels 22 in a controlledway making up a desired path 17. When the artificial tendon or tendons 2 are pulled bymeans of the actuator 13 the patches 25 will transfer the bending forces to a finger presentin the finger portion 1. The patches 25 will also form a counteractive support during a grip-ping movement so that the artificial tendons 2 will not leave its path. Preferably, the at leastone finger portion is covered by means of a glove like device. The glove like device is pro-vided with one or several guiding means 23 for the artificial tendons 2 and an actuator 13 for pulling of the artificial tendons 2.
    Application text 2016-05-30 160018SE According to another embodiment the material 3 of the finger portion 1 is provided by afinger of a glove like device, where the at least one artificial tendon 2 is arranged at the inside ofthe glove like device. 220 Application text 2016-05-30 160018SE
