Abstract
An arising aid to allow individuals needing assistance in raising from a seating position to a standing position. When the device is placed on a chair seat, the user may inflate bellows in the device by rocking from side to side. The inflated bellows raise the seated person to a near standing position, where the user may be able to stand without further assistance.
Claims16
An apparatus that is placed onto a seat for aiding a person in raising from a sitting position to a standing position, the apparatus comprising:
- a) a left pump chamber having an inlet port and an outlet port, the left pump chamber being constructed of a material impervious to air, the left pump chamber being biased to inflate;
- b) a first one-way valve connected to the inlet port of the left pump chamber;
- c) a right inflating chamber having a sealable outlet port and an inlet port, the inlet port of the right inflating chamber being pneumatically connected to the outlet port of the left pump chamber for receiving air from the left pump chamber, the right inflating chamber being constructed of a material impervious to air;
- d) a second one-way valve connected to the inlet port of the right inflating chamber;
- e) a right pump chamber coupled to and on top of the right inflating chamber, the right pump chamber having an inlet port and an outlet port, the right pump chamber being constructed of a material impervious to air, the right pump chamber being biased to inflate;
- f) a third one-way valve connected to the inlet port of the right inflating chamber;
- g) a left inflating chamber coupled to and underneath of the left pump chamber, the left inflating chamber having a sealable outlet port and an inlet port, the inlet port of the left inflating chamber being pneumatically connected to the outlet port of the right pump chamber for receiving air from the right pump chamber, the left inflating chamber being constructed of a material impervious to air;
- and
- h) a fourth one-way valve connected to the inlet port of the left inflating chamber.

A method of raising a person from a sitting position towards a standing position with the assistance of an arising aid which is placed upon a seat, the method comprising the steps of:
- a) inflating a left pump chamber;
- b) compressing the left pump chamber to force air from the left pump chamber into a right inflating chamber through a pneumatic connection having a one-way valve, whereby the right inflating chamber is inflated and the person is raised;
- c) inflating a right pump chamber;
- d) compressing the right pump chamber to force air from the right pump chamber into a left inflating chamber through a pneumatic connection having a one-way valve, whereby the left inflating chamber is inflated and the person is raised;
- e) repeating steps a) and b) until the left inflating chamber and the right inflating chamber are inflated sufficiently to allow the person to stand.
2 more elements
An apparatus that is placed onto a seat for aiding a person is raising from a sitting position to a standing position, the apparatus comprising:
- a) a top planar member having a front end, a back end, and a top surface;
- b) a bottom planar member having a front end, a back end, and a top surface, the front end of the bottom planar member being hinged to the front end of the top planar member;
- c) a left pump chamber coupled to the top surface of the top planar member, the left pump chamber having an inlet port and an outlet port;
- d) a first one-way valve fitted to the inlet port of the left pump chamber;
- e) a right pump chamber coupled to the top surface of the top planar member, the right pump chamber having an inlet port and an outlet port;
- f) a second one-way valve fitted to the inlet port of the right pump chamber;
- g) a right inflating chamber coupled to the top surface of the bottom planar member, the right inflating chamber having an inlet port and an outlet port, the inlet port of the right inflating chamber being pneumatically connected to the outlet port of the left pump chamber;
- h) a third one-way valve fitted to the inlet port of the right inflating chamber;
- i) a left inflating chamber coupled to the top surface of the bottom planar member, the left inflating chamber having an inlet port and an outlet port, the inlet port of the left inflating chamber being pneumatically connected to the outlet port of the right pump chamber;
- and
- j) a one-way valve fitted to the inlet port of the left inflating chamber;
- whereby the weight of the person onto the left pump chamber will force air into the right inflating chamber, inflating the right inflating chamber,
- whereby the weight of the person onto the right pump chamber will force air into the left inflating chamber, inflating the left inflating chamber,
- whereby the person shifting from right to left repeatedly will inflate the right and left inflating chamber, thereby forcing the top planar member to rotate away from the bottom planar member, forcing the person towards a standing position.
