1. Field of the Invention
This invention is directed to a reclinable chair for use in the alleviation of back pain. The chair may be used by Chiropractors as part of their treatment of clients in an office environment or may be used by individuals at home for example.
2. Description of Related Art
Several devices have been proposed for use as treatment apparatus for pain but few have been commercially successful due to their high cost and complexity. Examples of such reclinable chairs are disclosed in U.S. Pat. Nos. 7,654,974; 7,341,565; and 6,277,141. These devices are cumbersome to use and are quite uncomfortable.
The present invention is a relatively inexpensive and comfortable back pain treatment device designed for use in either a home or office environment.
A cushioned chair is tiltable from a horizontal position to an inclined orientation. The chair includes a back support portion and a second lower back, upper leg and lower leg support section that is movable in a first axial direction with respect to the back support section and is also arcuately movable about a pivot axis that is perpendicular to the axial direction. The chair includes remotely controlled linear actuators to control the relative movement of the different sections of the device. The chair may also include heaters and vibrators for additional therapeutic treatment.
Referring to
Horizontal support members 6 and 28 may have suitable castors 29 on their outer ends. Referring again to
Chair 2 also includes a lower body support member 17 that has three support sections 18, 19, and 20 integrally formed together as a unit. Surface 18 is adapted to support the lower back portion of a user, surface 19 supports the upper thighs of a user and surface 20 conforms to the lower legs beneath the knees. In use, the back of a user's knees will be located at point 22 of the lower support member. Lower body support member 17 is secured to a platform 27 which is mounted for reciprocal and oscillatory motion as will be explained later. As shown in
The internal mechanism for extending and retracting lower body support member with respect to box frame 4 will now be discussed with reference to
Stationary frame 60 includes a front wall portion 65 to which an electric linear actuator 56 including extension rod 57 is secured. The end of the extension rod 57 is attached to a cross beam 53 of the carriage member 50. Carriage member 50 includes upper and lower elongated plates 55 and 54 on each side and a vertical plate 91 extending between plates 55 and 54 on each side of the carriage. These plates are welded together and to an end plate 64. Each inner surface of vertical plate members 91 carries a longitudinally extending track member 58 which slides along a complimentary shaped track support 59 attached to the outer vertical surface of stationary frame 60. In this manner, as extension rod 57 of linear actuator 56 is extended or retreated, carriage member 50 will move accordingly.
Referring now to
As shown in
Frame member 85 extends upwardly at an angle from frame member 81. As shown in
The chair may be equipped with vibrators at various locations and also with heaters in any convenient location. Also a hand held wireless remote control or a wired controller may be used to control the various electronic elements of the chair including the vibrators, heaters, and electric linear actuators as known in the art. Electronic timers may also be included in the electronics to control the duration of the devices.
In use, a user may either lie horizontally on the chair in the position shown in
In either instance, the upper back of the user would be positioned along support section 16 of the chair. The user's lower back would be supported by section 18 of the chair. The user's legs would be supported at the thighs by section 19 and the lower legs would be supported by section 20.
Lower body support member 17 including sections 18, 19, and 20 can be moved back and forth as shown at 96 in
Although the present invention has been described with respect to specific details of an embodiment of the invention, it is not intended that such details should be regarded as limitations on the scope of the invention, except to the extent that they are included in the accompanying claims.
This application is a continuation of U.S. application Ser. No. 13/438,515 filed on Apr. 3, 2012, which is incorporated by reference in its entirety.
