Foldable body building device

Abstract

A foldable body building device is formed of a first connection rod mechanism and a second connection rod mechanism. The first connection rod mechanism is formed of an upright rod, a handlebar support rod, two titled support rods, and a connection rod of a base. The second connection rod mechanism is formed of an upright rod, a handlebar support rod, two damping pressure cylinders, and two swivel rods. The first connection rod mechanism is used to support the body building device in the unfolded state. The second connection rod mechanism is intended to bring about the linking action of the body building device.

Description

FIELD OF THE INVENTION

[0001] The present invention relates generally to a body building device, and more particularly to a foldable body building device.

BACKGROUND OF THE INVENTION

[0002] The conventional foldable body building devices are defective in design in that they can not be easily folded and unfolded, and that they are not structurally strong.

SUMMARY OF THE INVENTION

[0003] The present invention comprises a first connection rod mechanism and a second connection rod mechanism. The first connection rod mechanism is formed of an upright rod, a handlebar support rod, two tilted rods, and a connection rod of a base. The second connection rod mechanism is formed of an upright rod, a handlebar support rod, two damping pressure cylinders, and two swivel rods.

[0004] The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0010] As shown in FIGS. 1-5, a body building device 10 embodied in the present invention comprises the component parts which are described hereinafter.

[0011] A base rod 11 is provided in the midsegment thereof with a pivoting seat 12 having a shaft rod 13. The base rod 11 is further provided at both ends thereof with a connection rod 14.

[0012] An upright rod 21 is provided at the top end thereof with a pivoting seat 22 and is pivoted at the bottom end thereof to the pivoting seat 12 of the base rod 11.

[0013] A support rod 31 is provided at the top end thereof with a handlebar 32 and is provided at the top portion with a pivot seat 33 which is pivoted with the pivoting seat 22 of the upright rod 21. The support rod 31 further provided at the lower end thereof with a pivoting tube seat 34.

[0014] Two titled support rods 41 are provided with a connection tube 42 which is pivoted with the pivoting tube seat 34 of the support rod 31, a pivoting suspension seat 43, and a rod pivoting seat 44 connected with the connection rod 14 of the base rod 11.

[0015] Two swivel rods 51 are provided at the front end thereof with a pivoting tube portion 52 which is pivoted with the shaft rod 13 of the base rod 11, at the rear end thereof with a pedal board 53, and in the midsegment thereof with a pivoting seat 54.

[0016] Two damping cylinders 61 are pivoted at a cylinder end portion 62 thereof to the pivoting suspension seat 43 of the tilted support rod 41, and at a shaft end portion 63 thereof to the pivoting seat 54 of the swivel rod 51.

[0017] The connection rod 14 of the base rod 11, the upright rod 21, the support rod 31, and the tilted support rods 41 form together a first connection rod mechanism for supporting the body building device 10 in the unfolded state.

[0018] The upright rod 21, the support rod 31, the swivel rods 51, and the damping cylinders 61 form together a second connection rod mechanism for bringing about the linking effect of the body building device 10.

Claims
