Abstract
A toy seat comprises a base with a seat mounted for movement between different levels above the base and a fluid chamber in the form of a bellows supports the seat on the base to move up and down. A hand pump is provided for supplying pressurized fluid to expand the fluid chamber to raise the seat to a level wherein suddenly the pressurized fluid in the chamber may be released to the atmosphere and the seat then settles downwardly until the pressurized fluid is again supplied to the chamber by manual operation of the pump. The toy seat also includes a whistle which is associated with an exhaust or release valve so that a whistling sound is produced whenever pressurized fluid from the seat supporting chamber is released.
Claims12
A self-energizing exercising device utilizing the weight of the user as a resistive force, comprising:
- a base structure;
- a seat means for supporting the user mounted for movement between different generally vertical levels above said base structure;
- a flexible bellows type fluid chamber supporting said seat means on said base structure expandable and contractable to raise and lower the level of said seat means;
- bellows pump means for supplying pressurized fluid to expand said fluid chamber and actuable by a user while seated on said seat means;
- means for releasing pressurized fluid from said fluid chamber to lower the seat means from a selected upper position;
- and
- handle means operable in generally a rowing fashion by a user positioned on the seat means for operating the pump means including a hand graspable portion mounted for movement toward and away from the seat means so as to require substantial movement of the user's arms and torso.
A self-energizing exercising device utilizing the weight of the user as a resistive force, comprising:
- a base support structure;
- a pivot axis defined on a forward end of the base and extending transversely to the base;
- a seat means for supporting the user, said seat means being pivotally mounted on said pivot axis for movement between different generally vertical levels above the base support structure;
- a bellows type fluid chamber means supporting said seat means on said base structure, said chamber means being flexible and contractable to raise and lower the level of the seat means;
- bellows type pump means for supplying pressurized fluid to expand said fluid chamber;
- check valve means between said pump means and said fluid chamber means;
- and
- handle means for selectively operating said pump means in generally a rowing type manner while the user is seated on the seat means, said handle means including a hand graspable, generally elongated arm pivotally mounted on said pivot axis for movement toward and away from said seat means so as to require substantial movement of the user's arms and torso during reciprocation of said handle means.
A self-energizing exercising device utilizing the weight of the user as a resistive force, comprising:
- a base structure having a forward portion and a rearward portion;
- a seat means for supporting the user positioned above said rearward portion of the base structure for movement between different generally vertical levels above said base structure;
- a bellows type fluid chamber means supporting said seat means on said base structure and which is expandable and contractable to raise and lower the level of said seat means;
- a bellows type pump means for supplying pressurized fluid to expand said fluid chamber means;
- handle means for operating the pump means including a hand graspable portion mounted for movement toward and away from the seat means during a generally rowing type operation while the user is seated on the seat means, said handle means and said movable seat means being pivotally mounted on said forward base portion;
- and
- a pair of foot rests extending laterally outwardly from opposite sides of said handle bar means.
