20080203803 | Lumber Distraction Chair - Lumbar distraction is an effective treatment for back pain. However the discomfort and morbidities associated with vertical inversion has limited its use. The Lumbar Distraction Chair delivers a gentler lumbar distraction without the discomfort of being suspended vertically. The device is a modified office swivel chair with inward folding arm rests that secure the patient's legs on the chair seat. The patient positions him/herself onto the device with their back lying on the floor with hips and knees flexed. The arm rests of the chair fold inwards and hold the patient's legs securely onto the seat. A pneumatic telescopic stand elevates the seat, which also lifts the patient's legs hips and lower back off the ground by several centimeters. This provides lumbar distraction to the lower back. In this position, pain and inflammation is alleviated. This permits the muscle cell relaxation, recuperation and repair. | 08-28-2008 |

20100123346 | Adjusting Device Coacting Arm Rests in a Chair - An adjusting device which can be implemented in a chair and which can be utilized to coact with two arm rests thereof includes a first and second blocks aligned coaxially with each other. A first and a second plates which are adapted for connecting the two arm rests respectively are moveably attached to the first and second blocks respectively. An adjusting mechanism interconnects the first and second plates and is operable to urge the first plate with respect to the first block and the second plate with respect to the second block concurrently, and in which the first and second plates are moved oppositely by the actuating device. | 05-20-2010 |
20100219671 | WHEELCHAIR ARMREST ADJUSTING MECHANISM - The present invention provides a wheelchair armrest adjusting mechanism comprising a support unit having a horizontal support connected to a top of an upright support, and a plurality of locking units located one side of the horizontal support; wherein an armrest has a slide channel for engaging with the horizontal support, a stop hole for creating a passage to the slide channel in order to fit one of the locking units when the stop hole is aligned with the locking unit, and a control unit fitted in the stop hole for pushing against the locking unit. When the control unit is pushed and held, the armrest can be slid along the horizontal support to align with one of locking units; and when the control unit is released, the locking unit is pushed into the stop hole and thereby locks the armrest in place. | 09-02-2010 |
20110181090 | ROTARY ELBOW WITH DOUBLE SHAFT - A chair elbow capable of rotating with double shaft is disclosed. Two bearings are disposed on a mount board fixed on a chair. Each of the bearings connects one end of each of two rotating plates, while the other ends thereof are pivotally connected in a linear slot of a seat plate used for securing an armrest. The length of the slot is longer than the distance between the two bearings, and the latter is longer than the length of the rotating plates. Thus, the armrest on the seat plate can rotate against the mount board with 360 degrees and move forward and backward. | 07-28-2011 |
20110278898 | Adjustable Armrest Structure for a Chair - An adjustable armrest structure for a chair is an adjusting assembly fixed to bottom ends of two armrests on two sides of the chair and includes a body, two side rails, a movable member, the body including a guiding slot formed on a bottom end thereof to fit a screwing element and to engage with the movable member; wherein the guiding slot of the body includes a plurality of arcuate recesses arranged around the two sides thereof to fit two projections which are fixed on two sides of a guide member respectively, and an actuating member includes a bore disposed thereon and is fixed to the guide member so that the screwing element is inserted through the bore of the actuating member and an orifice of the guide member, and a screw segment of the screwing element is screwed with the aperture of the movable member. | 11-17-2011 |
20120025584 | ARMREST ADJUSTMENT DEVICE - An armrest adjustment device is revealed. The armrest adjustment device includes an armrest arranged at a top surface of an armrest support. The lower part of the armrest support is connected to a chair seat. The armrest can be adjusted to move forward and backward in relation to the chair seat. A first component is mounted in the armrest. The first component is assembled with and fixed on the armrest support so that the armrest can be moved forward and backward in relation to the first component. Moreover, a second component is arranged between the armrest and the armrest support. Instead of the first component, the second component is assembled with and fixed on the armrest support. Thus the armrest is moved in the left/right direction in relation to the second component. | 02-02-2012 |
20120112511 | ADJUSTABLE ARM FOR CHAIR - A chair arm adjustment device according to embodiments of the present invention includes an arm pad base slidably coupled to the arm support, the arm pad base sliding substantially horizontally in two degrees of freedom with respect to the arm support within a range of motion of the arm pad base with respect to the arm support, and an arm brake assembly coupled with the arm pad base, the arm brake assembly moveable between a locked position in which the arm brake assembly substantially inhibits movement of the arm pad base relative to the arm support and an unlocked position in which the arm brake assembly does not substantially inhibit movement of the arm pad base relative to the arm support, wherein the arm brake assembly moves from the unlocked position to the locked position at any position of the arm pad base within the range of motion. | 05-10-2012 |
20120175934 | ARMREST, IN PARTICULAR FOR AN OFFICE CHAIR - In order to provide an adjustment mechanism for the arm support of an armrest, which is particularly simple structurally and which also enables a particularly flat style of construction, a locking device is proposed for releasably locking the base platform and the carrier platform in different positions with respect to each other, said locking device comprising a transfer element, which is arranged between carrier platform and arm support and is connected to the base platform and which has first blocking elements for blocking the longitudinal adjustment of the arm support and second blocking elements for blocking the transverse adjustment of the arm support, and an actuating element, which is arranged between carrier platform and arm support and is provided with a control button for manual actuation and which has elements for simultaneously blocking or releasing the first and second blocking elements of the transfer element. | 07-12-2012 |
20140145490 | ADJUSTMENT MECHANISM FOR ARMREST - An adjustment mechanism for armrests is revealed. An armrest includes an armrest surface and a lower plate fastened to form a space for receiving a movable block. Thus the movable block is moved forward and backward and positioned in relation to the lower plate. A rectangular slot is disposed on the movable block and a rectangular piece is moved and positioned transversely therein. A round slot is set on the rectangular piece while a hat-shaped disc is mounted in the round slot and fastened elastically on a projecting rod of a bottom frame. By a positioning bump on the hat-shaped disc elastically mounted into or separated from a positioning hole arranged circularly on the projecting rod, the hat-shaped disc and the bottom frame are rotated and positioned in relation to each other in a 360 degree circle. Thereby the armrest can be moved transversely and rotated 360 degrees. | 05-29-2014 |
