F n'rramvn PATENTED SEP! 8 m3 SHEET 2 BF 2 BACKGROUND TO THE INVENTION This invention relates to a physical exerciser to be used for a large variety of physical exercises for training and strengthening the muscular system of the human body.

BRIEF DESCRIPTION OF THE DRAWINGS Embodiments of the invention will now be described, with reference to the accompanying drawings, in which:

FIG. 1 shows, partially in section, a first physical exerciser;

FIG. 2 shows a perspective view of the concertina spring of the physical exerciser of FIG. 1;

FIG. 3 shows schematically a second physical exerciser also partially in section;

FIG. 4 shows a modification to the physical exerciser of FIG. 3;

FIG. 5 shows schematically a third physical exerciser again partially in section.

DETAILED DESCRIPTION OF THE DRAWINGS Like parts are identified by the same reference numerals in each of the figures of the drawing.

Referring to FIG. 1, the physical exerciser shown has an inner metal tubular member I and an outer tubuler member 2, each having a handle 4. The tubular members l and 2 are arranged to form a telescopic unit. The spacing between the tubular members 1 and 2 is exaggerated to simplify the drawing, there being a sliding fit between them.

The handles 4 are hollow, being moulded from plastics material in two parts. A spigot 3 extends from the hand grip portion of each handle 4 and is received as a frictional fit in its respective tube 1, 2. For this purpose the spigots 3 are formed with splines 16 to ensure that their attachment is secure. The hand grip portions of the handles 4 are provided with depressions 15 to receive the fingers of a person using the physical exerciser.

The telescopic unit is axially compressible against the bias of a concertina spring 5 which is arranged within the tubes 1, 2 between the spigots 3 of the handles 4. Preferably the concertina spring 5 is fabricated from flat steel strip of 15 mm width.

The physical exerciser is provided with an endless rope l2 joining the handles 4 in order that the physical exerciser can be used for expansion (pulling) exercises, in addition to compression (pushing) exercises. By pulling the two lengths of the rope l2 transversely of the physical exerciser the telescopic unit is compressed against the bias of the concertina spring 5. Compression exercises are carried out by the user gripping one of the handles 4 in either hand and urging the handles 4 together against the bias of the concertina spring 5.

It is possible to employ a rope 12. comprising two separate parts arranged between the handles 4 on diametricallyopposite sides of the telescopic unit. The length of each part of the rope 12 is selected to ensure that in the relaxed attitude of the exerciser the concertina spring 5 remains under compression.

Referring to FIG. 3 of the drawing, the physical exerciser shown is generally similar to that described with reference to FIG. 1. This physical exerciser comprises a first tubular member 1 carrying at its outer end a handle 4 and an elongated member 8 attached at its outer end to a similar handle 4. The member 8 is telescopically slidable within the tube 1 and a sliding fit through a bush 7 at the inner end of the tube 1. The member 8 carries at its inner end a flange 17 which is a sliding fit within the tube 1. At least one extensible resilient member 16 extends between and is secured to the bush 7 and the flange 17. A rope having two lengths 12 extends between the handles 4, The rope may be endless passing through

apertures

13, 14 in the handles 4 or it may be in two separate lengths secured to the hand grips. A second tubular member 2 is secured to the handle 4 (of the member 8) to embrace the tube 1.

In the physical exerciser shown in FIG. 3 the resilient member 116 may be a single coil spring embracing the member 8 and secured at its ends to the bush 7 and the flange 17. Alternatively the member 116 could be a multiplicity of coil springs surrounding the member 8 and also secured to the bush 7 and the flange 17. It will be understood that whatever the nature of the member 16 it is so arranged in relation to the lengths of rope 12 that the member 116 remains in slight tension when these lengths are taut.

In FIG. 3, chain lines 18 indicate compressible resilient means extending between the flange l7 and the closed end of the tube 1 adjacent the handle 4. The resilient means 18 could be a single coil compression spring (FIG. 4) one or more concertina springs formed from a strip of resilient material (FIG. 1) or the space between the flange 8 and the closed end of the tube 1 could be wholly or partially filled with compressible material (see FIG. Such compressible material could comprise a number of balls of rubber, sponge rubber, or plastics material either solid or hollow.

FIG. 4 shows a further modification in which a coil compression spring 19 is shown embracing the member 8 to act between the bush 7 and the closed end of the tube 2 adjacent its handle 4. Again it will be understood that the spring 19 could be replaced by one or more concertina springs as described above or a multiplicity of balls or blocks of compressible material of annular formation. In addition FIG. 4 shows the resilient means 18 in the form of a coil spring embracing a rod 20 extending coaxially through the tube 1 from its handle 4 and having its forward end slidable through the flange 17 to extend within the member 8 which in such case is of tubular form.

It will be understood that the resilient means serving to resist movement of the handles 4 towards each other may be solely compressible in any of the forms described. When coil compression springs are employed it would be advantageous to encase them in sleeves of plastics material.

FIG. 5 of the drawing shows a third physical exerciser arrangement of simplified construction generally similar to that shown in FIG. 1, where the member 8 is in the form of a piston directly slidable within the tube 1 and a multiplicity of resilient balls 18 is disposed between the inner end -21 of the member 8 and the end of the tube 1 closed by its handle 4. As described above the balls 18 may be of rubber, sponge rubber or other resilient material either solid or hollow.

In each of the arrangements shown in FIGS. 3 to 5 the spigots 3 are not shown. It will be appreciated that it is a simple matter to mount the member 8 in the spigot 3 of the handle 4 carried by the tube 2. For this purpose the spigot 3 can be provided with a recess in which the outer end of the member 8 is a frictional fit.

In all the above arrangements it will be understood that the apparatus may be provided with a sliding scale performance meter by calibrating the outer surface of the tube 1 with graduations.
