Abstract

The apparatus includes "selection pins" to select the number of weights to be included in a weight stack or to adjust the angle of an exercise bench. The apparatus includes a body with a series of apertures (7, 8, 9, 10) and at least one selection pin (14) arranged to pass through selected ones of the apertures so as to set a predetermined exercise. The selection pin is provided with magnetic retaining means for restraining movement of the selection pin transverse of the elongate body.

Description

Fitness Apparatus.
The present invention is concerned with fitness apparatus and, in particular, fitness apparatus involving the use of selection pins.
Selection pins are used in multi-station and single-station gymnasium or exercise equipment to select the number of weights to be included in a weight stack. They are also used in, for example, exercise benches to select the angle of the bench.
Selection pins of this type are subject in use to repeated impact, as for example, a stack of weights are raised and lowered, or as a user raises and lowers his body. This can cause the pins to vibrate loose and ultimately drop out of their respective location position, with consequent risk of serious injury to the athlete. This may occur especially on high repetition rate units and on units where a selection pin has become distorted or bent. On unsupervised exercise units where the selection pin is not visible to the user, the pin can vibrate out of the location hole unnoticed by the user.
It is an object of the present invention to at least alleviate this problem; according to the invention, therefore, there is provided fitness apparatus having at least one elongate body member with a plurality of apertures therethrough, arid at least one selection pin capable of passing through selected ones of said apertures and thereby setting a predetermined exercise, in which the selection pin is provided with magnetic retaining means for restraining movement of the selection pin transverse of the body member.
The apertures in the body member are generally sequentially spaced at regular intervals. In one preferred embodiment of the present invention, the body member comprises a vertical weight support member having a stack of weights (typically in the form of bar weights) suspended therefrom by a corresponding series of the selection pins.
The or each selection pin typically has a handle at one end, generally integrally formed with the body of the pin. The pin is preferably of steel rod stock.
The magnetic retaining means is typically secured to the pin adjacent the handle, and may comprise a flange at right angles to the axis of the pin shaft. This flange may comprise an annular, or part-annular permanent magnet. Typically, the magnet is a resilient magnet such as the magnets marketed under the trade mark Placam by Magnetic Applications Ltd, or a ring magnet welded to, or otherwise secured to, the selection pin. The magnet should in any case be capable of magnetic engagement with appropiate weights retained in a stack on the body member. In other embodiments, the pin itself may be magnetic, a magnet may be provided at the distal end of the pin, or a magnet may be provided on the weights in a weight stack.
It is particularly preferred that the handle be eccentrically offset (in use, vertically downwardly) relative to the axis of the pin shaft; it is also preferred that the magnet also be eccentrically offset, but in the opposite sense (that is, in use vertically upwardly). This enables maximum area of contact with a weight in a weight stack when the pin supports the weight in a channel in the base thereof rather than passing therethrough. Typical embodiments of the present invention will now be described by way of example only with reference to the accompanying drawings, in which:
Figure 1 is a side elevation of a selection pin suitable for use in fitness apparatus according to the invention;
Figure 2 is a side elevation of a modification of the selection pin illustrated in Figure 1;
Figures 3a and 3b are respectively end and side elevations of part of a weight stack for use in fitness apparatus according to the invention together with a selection pin such as illustrated in Figure 1.
Figure 4 is a schematic view of a fitness bench which may incorporate a selection pin such as illustrated in Figure 1.
Referring to Figure 1, there is shown a pin having a shaft 1 (the diameter and length of which is dependent on the particular equipment in which it is used) , the pin having a handgrip 2a or 2b (alternative shapes being shown in dotted lines) . Adjacent the handgrip is a ring 3 welded around the shaft; an annular magnet 4 is secured thereto.
Referring to Figure 2, in which like parts are denoted by like reference numerals, the pin has a shaft 1 with an offset handgrip 2c at one end thereof. A part-annular flange 3a is welded to the shaft adjacent the handgrip 2c; the flange 3a has a "horseshoe" type magnet 4a secured thereto.
Referring to Figures 3a and 3b, a vertical weight support shaft 6 has a sequence of throughbores 7, 8, 9, 10; a stack of weights 11, 12 are suspended from the shaft by the use of selection pins 13, 14 passing through respective throughbores 8, 10. Pins 13, 14 may be as illustrated in Figure 1 or 2; alternatively, or additionally, such a pin may be provided with a strip magnet 15 at its distal end 16. It will be noted that weight 11 has a throughbore 17 for receiving pin 13; weight 12, in contrast, has a channel 18 in its lower face for receiving pin 14. When the pin is received in such a channel, the pin is preferably as described above with reference to Figure 2.
Referring to Figure 4, an inclined fitness bench 20 is supported by an upright shaft 21 having a series of holes 22, 23, 24 etc. A selection pin 25 is passed through an appropiate one of the holes to support the bench 20 at the desired angle. The selection pin 25 may be as described above with reference to Figure 1 or 2; the pin is provided with a magnetic means for retaining it in the fully inserted condition so that it does not come out on repeated exercise.
