Exercise machine for exercising upper body portions

Abstract

An exercise machine has seat and back rest portions which are hinged to each other and independently pivotally supported on a support frame. The seat and the back rest portions are initially in a horizontal position to enable the user to exercise in a lying down position. The seat has an adjuster by means of which it can be angularly lowered to any one of a number of positions with the rear portion lowered more than the front portion. The front portion of the back rest which is hinged to the rear of the seat is lowered along with the seat to bring the back rest to the selected upwardly angulated position. A pair of lever arms are connected together at their inner ends and extend angularly outwardly from each other. Weights are connected to the inner ends and handles are connected to the outer ends for grasping by the user. Height adjusters are provided on the handles and arms to enable adjustment for persons of different sizes.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to exercise machines for exercising the upper body portions and more particularly to such a machine which can be adjusted between horizontal and selected angulated vertical positions.

2. Description of the Related Art

Exercise machines for exercising the upper body by providing handles for the user to push upwardly and downwardly against a weighted load are in general use. Such prior art devices are described in U.S. Pat. No. 6,179,757 issued Jan. 30, 2001 to Koenig and U.S. Pat. No. 5,437,589 issued Aug. 1, 1999 to Habing. Such prior art machines are not adapted to be adjusted from a position at which the seat and back rest are horizontal to one of a number of positions vertically angulated relative to the horizontal. Further, these prior art systems do not show arm operated levers which run angularly inwardly towards each other from the lever handles. The above indicated features of the present invention provides greater versatility in the use of the system and makes for more natural lifting action of the weighted levers.

SUMMARY OF THE INVENTION

The machine of the present invention utilizes a seat and back rest which are hinged to each other calibrated adjustment lever is provided on the seat by means f which the seat can be lowered to one of a number of selected positions with the portion connected to the back rest being lowered more than the front portion. The seat portion carries the lower part of the back rest along with it, bringing the back rest to a preselected angular vertical position. Thus, the machine can be used for a number of different types of exercises merely by a simple adjustment of the seat and back rest.

A pair of opposing lever arms are connected together through a swivel bracket on one end thereof a d supported pivotally on the support frame. The two arms run outwardly from each other at an angle of about 35 degrees. Handles re attached to the other end of the arms which are free. Adjustments are provided to adjust the position of the arms and the eight of the levers to accommodate various size persons.

It is therefore an object of this invention to provide an improved upper body exercise machine i which the positions of the seat and back rest can be readily adjusted to a selected position between horizontal and angulated vertical positions.

It is a further object of this invention to provide an upper body exerciser in which the seat a d back rest can readily be set in any one of a number of different positions.

Other objects of the invention will become apparent in view of the following description taken in connection with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to the FIGS, a preferred embodiment of the invention is illustrated. As can best be seen in FIGS 6-11, seat 12 is pivotally supported on frame 14 by means of support 15 which is adjustable to bring the seat downward to selected positions. This d result is achieved by means of gauge 16 which has an arcuate series of adjustment apertures formed therein. The support includes forward and rear post portions 15a and 15b interconnected by a horizontal cross piece 15c to form a four-bar linkage with the frame 14. Sup 15 has a pin 15d which fits into any selected one of these apertures to position the seat and the attached back rest 13 at a desired position between horizontal and down adjacent to the se of frame 14. The back rest is pivotally supported on post 19 which has an adjustment member 19a for adjusting its height. The front end of back rest 13 is hinged to the rear of seat 2 and thus moves with the seat with its forward end moving downwardly as the seat is moved downwardly and with its rear end moving upwardly, as shown in the various Figures.

Referring to FIGS. 1-5, the arm exercise mechanism is illustrated. Frame 14 has a base portion 14b, side portions 14c and 14d, and an upper central portion 14e which runs normally to base portion 14b. Lever arms 22 and 23 are pivotally connected together at one end by swivel bracket assembly 26 which is supported on the upper central portion 14e of the frame 14. Swivel bracket assemble 26 comprises swivel brackets 20 and 21 horizontally angulated relative to each other with the pivot axes of the swivel brackets occupying a common plane with the central upper portion 14e of the frame 14. The arms extend outwardly away from each other at an angle of about 35 degrees between each arm and a longitudinal axis of the upper central portion 14e. Handles 28 are attached to the opposite free ends of the arms for grasping by the user. At a position between the opposite ends of the arms, the arms are pivotally on frame 14 by means of pivotal support 30. Vertical adjustment apertures 14a are provided in the frame to permit the height of the arms to be set for persons of different sizes. As shown in FIG. 3, adjustment apertures are provided in the attachment posts 28a of handles 28 to accommodate various size persons. In addition, the posts can be rotated 180 degrees to accommodate the situation.

Posts 32 extend outwardly from the sides of the levers for mounting weights 33.

The user can exercise from a reclined position as shown in FIG. 8, a semi-reclined position, as shown in FIG. 9 or a near upright position as shown in FIG. 10, merely by adjusting the machine to these various positions, as shown in FIG. 6.

While the invention has been described and illustrated in detail, this is intended by way of illustration and example only, the scope of the invention being limited by the terms of the following claims.
