Telescoping Door Mount Exercise Bar

Abstract

A door-frame mounted exercise bar having two ends, each covered by a frictional, compressible substance, wherein said exercise bar is lengthwise adjustable by means of a ratchet operated strap, thus allowing the user to securely fit the exercise bar into a door-frame. The exercise bar has attachment points for elastic straps and other devices and mounting posts on its top surface. A stabilizer / attachment bar is provided having mounting sleeves aligned to coincide with, and attach to, the mounting posts on top of the exercise bar. These mounting sleeves also serve as attachment points for handles, exercise bars, and other accessories. The stabilizer / attachment bar is lengthwise adjustable such that the ends of the bar may be fixably insinuated behind the door stop molding found on most doors. When thus deployed, the stabilizer / attachment bar prevents the exercise bar from rotating when used.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]Not Applicable.FIELD OF THE INVENTION[0002]The present invention relates to an exercise bar with attachments that can be adjustably mounted in a door-frame. In particular, the device uses a ratchet strap mechanism to secure the exercise bar at a fixed position in a door-frame. By actuating a release lever, the ratchet strap mechanism is loosened thus allowing easy movement of the exercise bar and attachments to a new vertical position in the door-frame or a new door-frame.BACKGROUND OF THE INVENTION[0003]Door-frame mountable exercise devices are a common means to provide a user with a versatile, relatively compact and affordable exercise bar. These devices can be useful in a variety of exercise routines, which are often dependent on the location of the exercise bar within a door-frame. For instance, a bar fixed at the bottom portion of a door-frame can be useful in assisting in push-up and sit-up style exercise activities, whereas a bar f...

AI Technical Summary

Benefits of technology

The patent describes a device that allows users to exercise in the safety of their doors. The device includes handles and other accessories that are attached to a mounting sleeve. The device also has extendable tubes that limit the rotational movement of the exercise bar. To move the bar up or down in the door frame, the user can release the pressure on the outer pads against the door frame by sliding a bar into the center, release the screws to push the tubes into the horizontal stabilizer tube, and position the bar at any appropriate height in the door frame. Overall, the device provides a secure and safe way to exercise in the privacy of user's doors.

Problems solved by technology

However, one obstacle for such devices is that the exercise bar must be able to support a substantial load, at least the user's full body weight, while also providing for easy adjustment of the bar when a new position is desired, or a new length is required to fit door-frames of varying widths.

However, such devices may fail under substantial loads.

This device suffers from at least three weaknesses, to wit: 1) it is incapable of resisting rotational forces about the long axis of the exercise bar; 2) because of the design of the cam actuating mechanism, additional securing force is provided only when the bar is pushed up or pulled down and thus unsuited to withstand pulling or pushing forces from the front or the rear of the bar; and, 3) the bar is mechanically complex and thus costly to manufacture.
