  • Patent number: 11606991
    Abstract: A grip strengthening device having a finger portion for enhancing the grip by means of at least one artificial tendon arranged along at least one finger portion, wherein the finger portion comprises material along both sides and a tip, and possible along a dorsal side, the at least one artificial tendon is attached along both sides so that the artificial tendon may move, wherein the artificial tendon runs 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, the finger portion will transfer a force to provide a movement of the finger when the artificial tendon is retracted, wherein the artificial tendon runs in a detour towards or to a position in the middle between the dorsal and ventral side or closer to the dorsal side at a proximal portion of the finger portion.

  • Publication number: 20210196554
    Abstract: A tendon actuated hand enhancer (1) having a force anchoring device (2), comprising a rigid band (8), circumventing more than half of a circumference, but is bendable in the circumferential direction. At least one pulling point (6) for at least one artificial tendon (3) is provided at the force anchoring device (2). The force anchoring device (2) is provided at the tendon actuated hand enhancer (1) at a position corresponding to carpal and proximal portion of metacarpal bones of a user's hand when the hand enhancer (1) is in use, and a pulling means (4) for pulling the at least one artificial tendon (3) is connected to the hand enhancer (1).

  • Patent number: 10980697
    Abstract: Provided is a technique for attaching an artificial tendon to a support device having a supporting material as well as a product formed by the technique. The artificial tendon is provided for flexing or extending a joint of a body, when applied at the joint of the body, by way of pulling the artificial tendon along its lengthwise direction. The artificial tendon is attached to the support device by stitching across the tendon with a thread on the supporting material of the support device, which forms a tunnel for the artificial tendon between the supporting material and the stitching. The artificial tendon is able to travel in the tunnel. The tunnel formed by this technique is positioned on the surface of the supporting material of the support device.

  • Patent number: 10786022
    Abstract: Control system (200) for a strengthening glove (100) with fingers (101-105), comprising a force detecting sensor means (210) for detecting, at different measurement locations (211-218) on the palm side (106) of said glove fingers, a respective force between a finger (11-15) and a contact surface, further arranged to impart a force to respective glove fingers, bending them towards a gripping position, further arranged to read measurement values from the strengthening feedback loop based upon the measurement values. The invention is characterised in that a predetermined pattern is detected, comprising certain measurement values, in that, when the said pattern is not detected and the actuating means are controlled according to a first program, and further when the said pattern is detected, they are controlled according to a second program, which first and second programs are different.

  • Publication number: 20180296421
    Abstract: A method of attaching an artificial tendon (1) at a support device having a supporting material (2), the artificial tendon is provided for flexing or extending a joint (3) by means of pulling the tendon, stitching (5) across the tendon with a low friction thread, forming a tunnel (12) for the tendon between the supporting material and the stitching, in which the tendon may travel. A tunnel for an artificial tendon to be able to travel in, positioned at a surface of a supporting material of a supporting device, formed by the supporting material and a stitching across the tendon, the stitching comprising a low friction thread. A strengthening glove having artificial tendons for flexing or extending at least one finger, characterised in that the tendons run in a tunnel formed by the supporting material and a stitching across the tendon.

  • Patent number: 8029414
    Abstract: A finger glove for use in gripping movements with one or more fingers of a human hand enclosed in the glove. The glove includes glove fingers and a palm. At least one glove finger is adapted to include on each side an artificial tendon that extends along an inside of the glove. A yoke is fitted in a tip of the at least one glove finger and intended to surround a tip of an enclosed finger. At each side of the glove finger artificial tendons are connected to the yoke. A system including the finger glove having a force detecting sensor is situated on the inside of the at least one glove finger and is adapted to detect a force between a finger enclosed in the glove finger and a contact surface applied to the finger.
