Supporting mechanism for a deck frame of a folding-up treadmill

Abstract

The invention relates to a supporting mechanism for a deck frame of a folding-up treadmill having a support frame, a base frame and a deck frame. The supporting mechanism includes a supporting rod with one end connected to the base frame and with the other end connected through an extension spring to an extension piece of the front roller is interposed between the base frame and the deck frame. A slide wheel is provided between the supporting rod and the inner side of the deck frame. The slide wheel is cooperative with a supporting piece 38 at bottom end of the deck frame to create a supporting effect.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention relates to a supporting mechanism for a deck frame of a folding-up treadmill with economical, durable and easy-to-use features. This supporting mechanism serves to support the deck frame of the folding-up treadmill when the deck frame is folded up in storage position. [0003] 2. Description of the Related Art [0004] Conventional treadmills have a large volume. In order to diminish occupied space and to facilitate their transport, a folding-up device is fitted for the deck frame of the treadmills. However, the deck frame in storage position creates a tremendous loading to the base frame. Moreover, in order to prevent the deck frame from unexpected dangerous toppling, a supporting mechanism is interposed between the deck frame and the base frame to provide proper supporting force. [0005] The most commonly used so-called supporting mechanism is pneumatic and hydraulic cylinder. In folding up the deck frame...

AI Technical Summary

Benefits of technology

[0010] It is a primary object of the present invention to remove the above-mentioned drawbacks and to provide a supporting mechanism for a deck frame of a folding-up treadmill which utilizes a supporting rod with simple configuration instead of conventional pneumatic or hydraulic cylinder. Accordingly, the fabricating cost of the supporting mechanism can be effectively reduced. Moreover, the supporting mechanism in accordance with the present invention is more durable and easier to use. Besides, the functionality of the supporting mechanism is more easily identifiable so that the using safety is more ensured. Furthermore, the service life of the supporting mechanism in accordance with the present invention is longer than the conventional pneumatic or hydraulic cylinder, thereby avoiding the unnecessary servicing cost. Moreover, the invention is a practical design for the operator.

Problems solved by technology

However, the deck frame in storage position creates a tremendous loading to the base frame.

The pneumatic or hydraulic cylinder is very expensive; 2.

The service life of the pneumatic or hydraulic cylinder is very limited due to the larger loading.

It's often defective before the warranty expires, thereby resulting in much trouble and cost to the suppliers.

Meanwhile, the commercial reputation is also tremendously damaged.

Besides, this causes much inconvenience to the operators, too; and 3.

The operator can't still realize something wrong with the pneumatic or hydraulic cylinder from their appearance when they are so damaged that they are no more usable.

Provided that the deck frame unexpectedly topples down, this would endanger the operator or even people and objects around him.
