A type of spring-loaded leg base includes a base, a spring, and a connecting component. The base has a hollow chamber. The spring is placed inside the chamber. The connecting component is a unified component of a leg sleeve, a connecting bar and a spring cap. By passing the connecting bar through the grooved track and placing the spring cap on the top of the spring, the leg sleeve can be locked in position on the chair frame to create flexible support. This mechanism creates the rocking function for a regular chair.

A mobile support for seats (1) comprising a support bar (2) for the seats (1) which has feet (3) for resting and moving on a floor (4) of the installation site of the seats (1), wherein each foot (3) comprises a casing (5) which in the lower portion incorporates anti-slip blocks (6), while inside of said casing (5) an articulated structure (7) is arranged provided with wheels (8) which can tilt between an upper position wherein they stay above the bearing level of the anti-slip blocks (6) and a lower position wherein the wheels (8) stay with a bearing point below the bearing level of the anti-slip blocks (6) for movement by rolling on the ground (4).

A base seat, which is adapted for being used with a bed or a chair, includes a fixation base, a rocking mount, a drive device, and a swivel mount. The rocking mount is disposed above the fixation base and reciprocatingly and inclinedly moveable relative to the fixation base. The drive device is disposed between the fixation base and the rocking mount to drive the rocking mount to reciprocatingly and inclinedly move relative to the fixation base. The swivel mount is disposed above the rocking mount and rotatable relative to the rocking mount. By rotating the swivel mount and driving the rocking mount to reciprocatingly and inclinedly move, the bed or chair, which is fixedly mounted to the swivel mount, is swingable in a desired direction.

Provided is a chair including a support member that is at least a seat body and a backrest to support an occupant. The support member includes a composite portion at least a part of an outer periphery of the support member. The composite portion includes a first outer periphery that is a part of the first member and a second outer periphery that is a part of the second member. The first outer periphery and the second outer periphery are arranged to overlap each other in a thickness direction of the support member. In the composite portion, at least a part of the first outer periphery is formed into a thin portion thinner in the thickness direction than a part located on an outside of at least the part of the first outer periphery in the first member.

The swinging apparatus includes a base, a support located above the base, a coupler disposed between the base and the support and including a universal joint, and linear actuators disposed between the base and the support. Each of the linear actuators includes a first end and a second end located on an opposing side to the first end. The first end is mechanically connected to one of the base and the support. The second end is configured to freely move touching a surface of the other of the base and the support.

A furniture leg protective sock is constructed of a stretchable/expandable non-friction material, which forms an outer surface and an inner surface. The furniture leg protective sock includes non-penetrating material to prevent the furniture leg from piercing through the non-friction material.

The invention relates to a foldable chair that comprises a seat (1) and a back (2) available according to at least an angular position in which an angular distance between the same is minimum and another angular position in which the angular distance between the same is maximum; and first rotational means configured to define a first axis of rotation and arranged for a first relative angular movement between the seat (1) and the back (2); in addition to second rotational means configured to define a second axis of rotation and arranged for a second relative angular movement between the seat (1) and the back (2). In accordance with this arrangement, the first rotational means and the second rotational means are arranged independently with respect to one another for independent angular movements of the seat (1) and of the back (2) with respect to one another.

A modular base system is provided that allows easy installation and maintenance in a row of motion seating units. Arms are easily removable from a base assembly. The base assembly also provides structure allowing easy installation and removal of the motion mechanism. The base assembly also allows easy installation and removal of a back panel. The motion mechanism includes a pivotal seat frame attachment allowing the seat to be pivoted upwardly, from the front of the mechanism.

Disclosed is a frame assembly for a folding type chair that are folded or unfolded once by coupling a plurality of upper and lower supports configuring a main frame of a chair to be operatively associated.

A swivel base assembly, for use in conjunction with an electrically powered chair, is disclosed. The swivel base assembly provides the necessary electrical power to the electrically powered chair without the electrical power cord becoming entangled around the upstanding column, or similar support structure, upon which the body portion of the electrically powered chair is mounted upon the swivel base assembly if the electrically powered chair is rotated multiple times through means of an angular displacement or movement of 360 or more, as a result of the disposition of a rotary electrical connected interposed between the swivel base assembly and the electrically powered chair.
