Abstract

The disclosure describes a gymnastic balance beam which is provided with several standing or walking faces. The beam itself is in the form of an elongate body whose ends can be locked in various positions which are selected by axially rotating the body and fixing the ends. Each end of the elongated body includes a portion which has four flat faces with a bore in each face to receive a dowel which is positioned in each seat that receives the elongate body. The main walking section of the elongate body which is intermediate the ends thereof has as many different walking surfaces as there are positions which can be selected.

Claims

1. A gymnastic balance beam which comprises:

(a) an elongate body for horizontal mounting;

(b) said elongate body being terminated at both ends with a portion which is square in cross-section, said portion having four flat faces;

(c) a pair of seats;

(d) each said seat being U-shaped to define a recess adapted to receive both end portions of said elongate body;

(e) said elongate body having a means at both ends to lock the elongate body in a position which is selected by axially rotating said elongated body, said locking means including a bore formed in each said flat face and normal thereto to extend transversely into said elongate body;

(f) a dowel at the bottom of said recess to be inserted into one of said bores to selectively lock said beam in a plurality of positions which are selected by axially rotating said elongate body;

(g) main walking sections intermediate said square portions, said main walking sections having as many different widths of walking surfaces as there are positions which can be selected.

2. A gymnastic balance beam according to claim 1, wherein said main walking section have four different walking faces.

3. A gymnastic balance beam according to claim 2, wherein said main walking section consists of:

(a) two surfaces which are parallel to one another and which differ in width;

(b) a third surface which connects both said parallel faces and is wider than both of them, said third surface being oblique with respect to both said parallel surfaces;

(c) a fourth surface which is formed by the merging of two oppositely oblique faces which define an apex, said apex forming a longitudinal sharp walking edge on the fourth surface of said main walking section, said fourth surface connecting said two parallel surfaces.
