DESCRIPTION OF PREFERRED EMBODIMENTS
Referring now to FIGS. 1-7, the present invention features a motorized chair device 100, e.g., a motorized rocking chair, which provides controlled motion to an individual. The motorized chair device of the present invention may be particularly useful for individuals with limited motor functions. The motorized chair device may help promote better movement, balance, equilibrium, and vestibular processing and integration. For example, the device can help an individual develop gross motor arm control. In some embodiments, the motorized chair device helps improve cognizance, head control, eye contact, imitative behaviors, direction-following skills, and visual tracking skills. The device may be particularly soothing to users. Additional benefits may include but are not limited to: provides kinesthesia/sensory system benefits (e.g., provides information from muscles, joints, ligaments), provides internal awareness about body parts to allow user to perform tasks with coordination, provides motor planning (e.g., ability to organize, plan, and execute new or unplanned motor tasks), improves tactile/movement/kinesthetic-proprioceptive processing, increases body awareness, facilitates progress in motor skills, increases independence, teaches cause and effect relationships, teaches how to focus on a purposeful action that the user can control and repeat (e.g., via a switch), facilitates learning, leads to better self-help, communication, and leisure skills, etc.
The motorized chair device 100 of the present invention comprises a chair component 105. As shown in FIG. 1, the chair component 105 comprises a seat portion 110 and a generally curved back support portion 120. A leg divider shaft 130 (e.g., an abductor) is disposed on the seat portion 110, functioning to separate the user's legs (e.g., help keep the legs from crossing). Straps 140 are disposed on the chair component 105 (e.g., on the back support portion 120) for securing the user in the chair component 105. The chair component 105 may be constructed in a variety of materials, for example the chair component 105 may comprise various materials (e.g., padding, etc.) for providing comfort to a user. FIG. 2 shows a back view of the chair component 105.
Referring now to FIG. 3 and FIG. 5, the chair component 105 is mounted atop a rocking component 205. For example, in some embodiments, the rocking component 205 comprises a first rocker 210 disposed on a first side and a second rocker 220 disposed on a second side. The rocking component 205 allows the device 100 of the present invention to rock like a standard rocking chair, which is well known to one of ordinary skill in the art. As shown in FIG. 3, the chair component 105 is positioned at the front portion of the rocking component 205.
A motor system 310 (e.g., 0.07/0.09 TE) is disposed on the back portion of the rocking component 205. The motor system 310 functions to automatically rock the device 100 of the present invention. As shown in FIG. 3 and FIG. 7, the motor system 310 comprises a piston 320 for mounting on a ground surface. The motor system 310 pushes against the piston 320 to pivot the device in a forward direction (e.g., rocking motion).
Referring now to FIG. 4, the motor system 310 is operatively connected to a control box 340. The control box 340 allows manipulation of the motor system 310, for example rocking speed and frequency can be manipulated. The motor system 310 is operatively connected to a power source. In some embodiments, the power source is a battery (e.g., marine battery) or an electrical outlet. In some embodiments, the motor system 310 is operatively connectable to an electrical outlet via a power cord 350. In some embodiments, the motorized chair device 100 of the present invention further comprises a means of plugging in other devices (e.g., other devices with buttons), so a user can practice turning devices on and off, for example via the push buttons of the devices.
As shown in FIG. 5 and FIG. 6, a footrest 150 is disposed on the rocking component 205 below the seat portion 110 of the chair component 105. The footrest 150 may provide comfort to the individual. Straps may also be disposed on the footrest 150 for securing the individual's feet, however the use of the straps is optional.
A user can control the device 100 of the present invention, allowing him/her to determine when he/she wants to engage in the controlled motion (e.g., the user can stop the device if he/she is tired). The device 100 comprises a control button 380 (e.g., see FIG. 1) operatively connected to the control box 340 and/or motor system 310. In some embodiments, the control button 380 is mounted to the device via a temporary attachment means (e.g., hook-and-loop fasteners). In some embodiments, a user may activate the control button 380 by gross motor arm movement. Without wishing to limit the present invention to any theory or mechanism, it is believed that such a control button 380 encourages purposeful movement and refinement of basic movement skills. The control button 380 may teach cause and effect relationships, how to use an object/switch, or how to pay attention. The control button 380 may provide various sensory experiences. The control button 380 may teach how to focus on an action he/she can control and repeat.
As an example, in some embodiments, the device comprises a fractional horse power DC motor, optionally with a speed controller. In some embodiments, the shaft output may be about 1⁄4′′ to 3⁄4′′ V long, In some embodiments, the input may be about 115V, which may be converted to about 24V with speed control. The device may comprise a tinier with an on/off feature and time settings, for example for about 5 minutes to about 60 minutes. The device may comprise a remote with an on/off switch feature and/or a momentary switch to start/stop. The present invention is not limited to the aforementioned examples and components.
Various modifications of the invention, in addition to those described herein, will be apparent to those skilled in the art from the foregoing description. Such modifications are also intended to fall within the scope of the appended claims. Each reference cited in the present application is incorporated herein by reference in its entirety.
Although there has been shown and described the preferred embodiment of the present invention, it will be readily apparent to those skilled in the art that modifications may be made thereto which do not exceed the scope of the appended claims.
