Safety device for motorized fitness equipment

Safety device for motorized fitness equipment description/claims

(a) Field of the Invention The present invention is related to a safety device for motorized fitness equipment, and more particularly, to a circuit breaker capable of executing emergency stop to the fitness equipment in operation.

(b) Description of the Prior Art

A motorized fitness equipment relates to one that provides active revolution in a given pattern when electrically driven for a user to achieve physical exercise or activity in conjunction with the revolution such as found in a motorized treadmill or a power leg rehabilitation assistive devices. Taking the motorized treadmill for instance, operation of a running deck is not caused by running motion of its user; therefore, to prevent the user from falling down, a safety device is needed to immediately break the circuit to stop the running deck when the running speed of the user fails to keep in pace with the speed of the running deck.

A conventional safety device 9 applied in a motorized treadmill as illustrate din FIG. 5 of the accompanying drawings is comprised of an accommodation trough 91 fixed to a control panel of the treadmill (not illustrated), a magnetic member 92 is placed in the trough 91, two conductive terminals 93 in circuit off status are disposed on one end of the trough 91, the trough 91 also contains a conduction device 94, and the conduction device 94 is provided with a conductive piece 95 to be conducted through both conductive terminals 93 in circuit off status when the conduction device 94 is placed into the trough 91. The conduction device 94 is disposed with another magnetic member 96 attracted to the magnetic member 92 disposed in the trough 91 for securing the conduction device 94 in the trough 91.

Where between the trough 91 and two conductive terminals 93 in circuit off status of the conventional safety device is related to a connected through space, even though the user upon feeling he/she is unable to keep up with the speed of the running deck has pulled the conductive device 94 out of the trough 91 is at the risk of falling down because that the user may fail to stop the running deck in time if any foreign object, e.g., liquid or other metal object) that is conductive happens to fall into the trough to conduct through both conductive terminals 93.

Furthermore, both of the trough 91 and the conductive device 94 are secured to each other in position by means of two magnetic members 92, 96, but both magnetic members 92, 96 are exposed in the air and are vulnerable to attract foreign matters to compromise magnetism after a longer period of operation to such extent that the conductive device 94 is prevented from being attracted in the trough 91 through normal magnetism thus to clear away from the trough 91; consequently, setting of the fitness equipment will be affected to cause quite a disturbance to the user.

Therefore, those problems found with the conventional safety device adapted to the motorized fitness equipment are the primary objectives the present invention attempts to solve.

The primary purpose of the present invention is to provide a safety device for a motorized fitness equipment to correct those problems found with the prior art by means of having an structure to combine a socket and a conductive device to ensure the circuit is broken upon the conductive device clears away from the socket while avoiding easy break up between the socket and the conductive device in a non-emergency incidence.

To achieve the purpose, the present invention includes a socket fixed to a motorized fitness equipment, two first slots are disposed at the center of the socket, two second slots are respectively provided on two opposite outer sides of both first slots, both of the second slots are in circuit off status and each second slot contains a metal clip that is electrically connected to the motorized fitness equipment, and a conductive magnet is disposed at a bottom of each first slot; and a conductive device connected to a human body is provided with two separate conductive terminals in the conductive device with each conductive terminal having both ends respectively disposed with a first extension and a second extension in a same direction, two first extensions from both conductive terminals are connected into both first slots and electrically connected to the magnet while two second extensions from both conductive terminals are connected into both second slots of the socket and respectively held by both metal clips.
