Abstract: A robotic prosthetic foot according to the present disclosure includes a coupling module having an upper portion to which a limb part of a user is coupled, a prosthetic foot module configured to be coupled to a lower portion of the coupling module and support a load of the user to enable the user to walk, and a joint module provided at the coupling module to enable the prosthetic foot module to rotate, wherein the joint module includes an elastic unit configured to compress and expand due to the prosthetic foot module rotating as the user walks and generate an elastic restoring force to facilitate the rotation of the prosthetic foot module.

Abstract: A luggage board apparatus for a vehicle includes an upper board and a lower board. The upper board and the lower board are capable of moving together in a vertical direction, and the upper board is capable of moving in a front-rear direction with respect to the lower board. A shopping cart may be seated, loaded and stored on the luggage board by using a slide rail provided on the luggage board and a slide roller coupled to the slide rail on the luggage board.

Abstract: An embodiment of the present invention provides a pull-out system comprising: at least two slide rails each having a fixed rail, a middle rail slidably arranged on the fixed rail, and a movable rail slidably arranged on the middle rail; and a synchronization means for synchronizing the movement of the movable rail, wherein the synchronization means comprises a roller unit, a synchronization bar connected to the roller unit, and a deflectable element having an end portion fixe to the roller unit and an opposite end portion connected to the movable rail, and the movable rail is configured to move as much as the amount of rotation of the roller unit.

Abstract: Proposed is a hinge device having tension maintaining function, the hinge device including: a winding member affixed to a main body of a mounted structure having an inner space formed therein; a hinge member affixed to a door that opens or closes the inner space and mounted on the winding member so as to enable the door to be pivotable; and a tension member having one end affixed to the winding member and the other end affixed to the hinge member, such that the tension member transmits a tension to the door when opening and closing the door.

Abstract: One embodiment of the present invention provides an actuator comprising: a housing having a mounting space part formed therein; a motor part provided inside the housing and generating power; a reduction gear part of which a plurality of gears respectively having an internal gear and an external gear sequentially engage with each other so as to transmit the power generated in the motor part; and a rod part engaging with the gear disposed at the last position, and linearly moving according to the rotation of the gear, wherein one of the plurality of gears is formed such that the internal gear and the external gear can rotate together or rotate independently.

Abstract: An embodiment of the present invention provides a pull-out system comprising: at least two slide rails each having a fixed rail, a middle rail slidably arranged on the fixed rail, and a movable rail slidably arranged on the middle rail; and a synchronization means for synchronizing the movement of the movable rail, wherein the synchronization means comprises a roller unit, a synchronization bar connected to the roller unit, and a deflectable element having an end portion fixe to the roller unit and an opposite end portion connected to the movable rail, and the movable rail is configured to move as much as the amount of rotation of the roller unit.

Abstract: A slide unit includes a fixed rail fixed to a main body, and provided with a first accommodation space, a movable rail connected to a drawer body to allow the drawer body to be pulled out from and pushed into the main body, provided with a second accommodation space, and configured to be movable with respect to the fixed rail, an inner rail configured such that a first end thereof is inserted in the first accommodation space and a second end thereof is inserted in the second accommodation space, so as to allow the movable rail to be slidable with respect to the fixed rail, and a plurality of slide balls inserted in the first accommodation space to be disposed between the fixed rail and the inner rail, and inserted in the second accommodation space to be disposed between the movable rail and the inner rail.

Abstract: A mascara comb allows a user to quickly apply mascara liquid to the eyelashes without forming clumps. On the upper surface of the mascara comb a plurality of protrusion elements are disposed so as to form a plurality of rhombus structures; the rhombus structures are configured so as to form a predetermined gap for applying the mascara liquid to the eyelashes while combing the eyelashes, wherein a diagonal line in the axial direction of the comb portion forms a rhombus longer than a diagonal line in the orthogonal direction orthogonal thereto; further, the rhombus structures function as a velocity adjustment mechanism for making the velocity with which the mascara liquid flows in the axial direction slower than the velocity with which the mascara liquid flows in the orthogonal direction; and the inside of the rhombus structures are a holding portion having a function of holding the mascara liquid.
