US 7,347,806 B2 · Rocking type exercising apparatus

Abstract

A wedge-shaped tilt provider is attached in contact with the bottom surface of a seat and the upper surface of a seat connection member of a rocking mechanism to set the seat to an initial inclined position relative to a reference position. By setting the seat to a forwardly inclined position from a horizontal position where the seated surface of the seat is set horizontal, the user straddling the seat can increase the amount of muscle activity of his or her rectus muscle of abdomen, or abdominal muscle. Further, by setting the seat to a rearwardly inclined position, the user straddling the seat can increase the amount of muscle activity of his or her back muscle such as paraspinal muscle. With use of a rocking type exercising apparatus having the above construction, a stress of exercise simulating horseback riding is given to the user by changing the position of the seat relative to the reference position by a certain degree of inclination, while rocking the seat which the user straddles, whereby the user is selectively provided with an exercising effect onto a specific site of his or her body.

Dependent claims

A rocking type exercising apparatus comprising:

a seat which is to be straddled by a user;
a tilt provider which provides the seat with a predetermined inclination angle relative to a reference position, said seat having the predetermined inclination angle as an initial state;
and
a rocker which provides a reciprocal rocking motion to the seat during use of the rocking type exercising apparatus with respect to the initial state thereof to apply a stress of exercise to the user,
wherein said rocker includes a top surface on which said tilt provider is mounted,
said tilt provider includes a top surface on which said seat is mounted, and
said predetermined inclination angle of said seat at said initial state with respect to the top surface of the rocker is inclined from a horizontal plane and is maintained during the reciprocal rocking motion of said rocker.

A rocking type exercising apparatus comprising:

a seat which is to be straddled by a user;
a tilt provider which provides the seat with a predetermined inclination relative to a reference position;
a rocker which rocks the seat during use of the rocking type exercising apparatus with respect to the initial state thereof in the inclination to apply a stress of exercise to the user;
and
a base member,
wherein the rocker includes:
a lateral rocking mechanism which is placed on the base member, and adapted to rock the seat about an axis extending in a longitudinal direction of the seat;
and
a longitudinal rocking mechanism which is carried by the lateral rocking mechanism, and adapted to rock the seat in the opposite longitudinal directions of the seat, and includes a front link member and a rear link member that are pivotable in longitudinal directions,
wherein the tilt provider includes:
a driver which drives the rear link member of the longitudinal rocking mechanism,
wherein the lateral rocking mechanism includes:
a pair of front and rear pin support flange members which are arranged in the longitudinal direction and fixedly attached to the base member;
a casing unit having a front plate, a rear plate, and a pair of side plates to define a space therein, the front plate and the rear plate being pivotally connected to the front and rear pin support flange members, respectively by pins;
a motor provided in the casing;
and
a first shaft which is provided between the both side plates of the casing unit, and is formed with an eccentric pin passing one of the both side plates, and is driven by the motor so that the eccentric pin allows the passing side plate to move in vertical directions to thereby cause a lateral rocking movement of the seat about the pins, and
wherein the longitudinal rocking mechanism further includes:
a second shaft which is provided between the both side plates and is driven by the motor, at least one end of the second shaft extending through the one side plate;
an eccentric crank member which is attached to the one end of the second shaft;
and
an arm link member which connects the eccentric crank member with the front link member.
