Benefits of technology

"The present invention provides a passive exercise equipment that can provide a constant sense of use regardless of the user's body type. The equipment includes a seat, footstools, and a seat driver. The footstools have a sole-surmounted part that can be moved up and down, and an elastic device to bias the part upward. The elastic coefficient of the elastic device is adjusted based on the user's body type. The equipment also has a body weight input part and regulatory drivers to automatically adjust the elastic coefficients. The footstools have a plurality of spring members and a bias adjuster that can switch between states. The invention simplifies the equipment and reduces production costs."

Problems solved by technology

However, the pantograph mechanism has a problem of increase in production cost owing to the complicated construction.
However, a body type differs among users, and thereby it disperses magnitude of load added to each footstool by weight difference of leg and so on and results in differences in depressing feel against the sole-surmounted parts.
Accordingly, the passive exercise equipment has a problem that constant sense of use cannot be secured.

first embodiment

[0026]A type of passive exercise equipment 1 in the present invention has an equipment base 20 put on a fixed position such as a flooring as shown in FIGS. a and 3, and is provided with a seat supporter 21 and a handle post 30 on the equipment base 20. The seat supporter 21 is equipped with a seat 2 for supporting buttocks of a user M on its top edge. The handle post 30 is equipped, on its top edge, with a handle 31 which the user M can grip as need arises. A footstool 3 of which top face is used as a sole-surmounted part 4 is placed at a position between the seat supporter 21 and the handle post 30 in the equipment base 20. Two footstools 3 are laid side-by side in a right-left direction, and the sole-surmounted parts 4 are surmounted by the right and left soles of the user M and thereby regulating the right and left feet placement.

[0027]The seat supporter 21 is a seat driver 50 for oscillating the seat 2 and an elevating mechanism 60 for moving the seat 2 and the seat driver 50 up...

second embodiment

[0060]In the first and second embodiment, the spring members 11 constituting an elastic device 6 are arranged in a linear fashion on a central line of a footstool 3 in a front-back direction. However, as shown in FIG. 8, the spring members 11 may be arranged in a voluntary fashion such as a triangular fashion in planar view. In FIG. 8, one spring member 11 is located at the front part of the footstool 3, and two unconnected spring members 11a are arranged side by side in a right-left direction at the rear part of the footstool 3. Each elastic operating part 14 of the extensible base members 15 is projected backward from the footstool 3.

third embodiment

[0061]FIG. 9 shows a This embodiment has a body weight input part 8 configured to input the body weight of a user M. Each bias adjuster 7 is provided with a regulatory driver 9 for adjusting the elastic coefficient of an elastic device 6. The controller is configured to perform drive control of each regulatory driver 9 in response to the body weight set through the body weight input part 8. For example, the operation display device 32 can include the body weight input part 8. For example, the regulatory driver 9 may be formed of a drive source 16 such as a motor, a solenoid or the like, and a mechanical section 17 that drives and slides the slide member 12 or drives and moves the extensible base members 15 up and down. However, other configuration can be adapted.

[0062]In this embodiment, a user M has only to input user's own body weight through the body weight input part 8, and the controller automatically sets an elastic coefficient of each elastic device 6 under the bias adjuster...

Abstract

This aims to provide passive exercise equipment capable of securing constant sense of use so as to avoid variation in depressing feel against sole-surmounted parts irrespective of body type difference among users. The equipment has a seat 2 for resting a user M on the buttocks, right and left footstools 3 for resting the right and left soles of user M sitting on seat 2 on, and a seat driver 5 for changing the position of seat 2 position to change load balance added to seat 2 and footstools 3 by user M, thereby changing the user's own weight acting on the legs. Each footstool 3 includes a sole-surmounted part 4 which a sole is placed on and meanwhile can be moved up and down, an elastic device 6 for biasing sole-surmounted part 4 upward; and a bias adjuster 7 for adjusting an elastic coefficient of elastic device 6.

Description

TECHNICAL FIELD[0001]The invention relates to passive exercise equipment which, in the condition that the soles of a user are put on footstools and the buttocks of the user are supported by a seat, drives and moves the seat, thereby changing the weight acting on the user's legs by own weight.BACKGROUND ART[0002]In the condition that the soles of a user are put on sole-surmounted parts of footstools and the buttocks of the user are supported by a seat, passive exercise equipment suggested conventionally moves the seat through a seat driver, and also moves the sole-surmounted parts up and down so as to substantially stabilize the position relation with the seat (see Japanese Patent Application Publication Nos. 2005-58733 and 2007-89650). In the passive exercise equipment, it is possible to change the weight acting on the user's legs by own weight to contract and relax muscle groups in the femoral regions while hardly bending and stretching the knees which place a burden on the user.
