Adjustable connection between an assistive device and a wearable device

An assistive device comprising a connector for mounting the assistive device to a wearable body, wherein the connector includes:

• a first connecting component to be mounted to one of the assistive device and the wearable body, and a second connecting component to be mounted to the other of the assistive device and the wearable body, the first connecting component further comprising at least one first holding member, and the second connecting component further comprising at least one second holding member,
• wherein the first connecting component and the second connecting component are connected to be non-rotatable with respect to each other in a plurality of holding positions and rotatable with respect to each other in other positions than the plurality of holding positions, wherein in the plurality of holding positions, the first holding member and the second holding member fit with each other such that when a torque smaller than a threshold value is applied, the first connecting component and the second connecting component are non-rotatably held relative to each other, and when a torque applied is greater than or equal to the threshold value, the first connecting component and the second connecting component are rotatable relative to each other to be out of the plurality of holding positions;
• and
• wherein the first connecting component has an outer peripheral surface, the second connecting component has an outer peripheral portion, the outer peripheral portion has an inner peripheral surface, the outer peripheral surface is rotatable relative to the inner peripheral surface, and the outer peripheral surface and the inner peripheral surface define an axis of rotation around which the second connecting component rotates relative to the first connecting component, wherein the first holding member is configured as grooves, and the second holding member is configured as a raised strip and in the holding position, the raised strip is located in one of the grooves.

A wearable device, comprising:

• a wearable body;
• an assistive device;
• and
• a connector for coupling the assistive device to the wearable body;
• wherein the connector includes:
• a first connecting component to be mounted to one of the assistive device and the wearable body, and a second connecting component to be mounted to the other of the assistive device and the wearable body,
• wherein the first connecting component comprises a first engaging member, the second connecting component comprises a second engaging member, and the first connecting component and the second connecting component are configured to rotate relative to each other into a separable position or into an engaged position,
• wherein in the separable position, the first engaging member and the second engaging member are separated from each other such that the first connecting component is separably engaged with the second connecting component in an axial direction,
• wherein in the engaged position, the first engaging member and the second engaging member are engaged with each other such that the first connecting component is inseparably engaged with the second connecting component in the axial direction,
• wherein the first connecting component further comprises at least one first holding member, the second connecting component further comprises at least one second holding member, and the engaged position comprises at least one rotation position where the first connecting component is rotatable relative to the second connecting component around the axial direction, and a plurality of holding positions where the first holding member and the second holding member mate with each other such that when a torque smaller than a threshold value is applied, the first connecting component and the second connecting component are not rotatable relative to each other and are held in one of the plurality of holding positions, and when a torque greater than or equal to the threshold value is applied, the first connecting component and the second connecting component are rotatable relative to each other to be out of the one of the plurality of holding positions;
• and
• wherein the first connecting component has an outer peripheral surface, the second connecting component has an outer peripheral portion, the outer peripheral portion has an inner peripheral surface, the outer peripheral surface is rotatable relative to the inner peripheral surface, and the outer peripheral surface and the inner peripheral surface define an axis of rotation around which the second connecting component rotates relative to the first connecting component, wherein the first holding member is configured as grooves, and the second holding member is configured as a raised strip and in the holding position, the raised strip is located in one of the grooves.
