Abstract

The exerciser is provided with a disc brake assembly in which a disc (40) is driven by pedal cranks (34) and the degree of resistance to rotation of the disc (40) is adjustable by a screw adjuster (44) acting on cantilever brackets (43) which carry friction pads (42). <IMAGE>

Description

SPECIFICATION Cycle type exerciser This invention relates to a cycle-type exerciser comprising a frame provided with a saddle, handlebars and pedal cranks to enable the user to perform a cycling action while remaining stationary. The frame may be wheel-less or it may be provided with one or more wheels in which event the wheels will be mounted so as to be out of contact with the ground.
In order to allow the effort required on the part of the user to turn the pedal cranks, it is known in the case of wheeled cycle-type exercisers to provide means for applying a selectively variable braking action to the wheel periphery. In the case of wheel-less frames, a band-type braking device is used to exert a variable frictional resistance to turning of the pedal cranks. Both forms of braking device tend to be relatively expensive to manufacture.
The object of the present invention is to provide a cycle-type exerciser with an improved form of device for regulating the effort required on the part of the user.
According to the present invention we provide a cycle-type exerciser in which the pedal cranks are drivingly connected to the disc of a disc brake assembly, at least one of the friction pad units of which is adjustable to vary the frictional resistance to turning of the pedal cranks.
In a preferred embodiment of the invention the disc is connected directly to the pedal cranks.
However if desired, the disc may be driven indirectly via gearing or other transmission coupling the pedal cranks to the disc.
Conveniently adjustment of the frictional force exerted by the pads on the disc can be effected through the agency of a device mounted on the handlebars or at some other location on the frame where the adjuster is readily accessible to the user whilst seated on the saddle. This however is not essential in that for reasons of economy the adjuster device may be mounted directly on the disc brake assembly. It may for instance comprise a knob with a stem screw-threadedly engaged with at least one of the pad units so as to vary the spacing between the pad units in response to turning of the knob.
The frame is conveniently of X-linkage configuration with ground-engaging cross-bars at one end of each link so as to maintain the frame stable in use and the saddle and handlebars provided at the opposite ends of the links, the frame being foldable about the point of intersection of the X-linkage from an in-use position to a stowed condition in which the links of the X lie generally alongside one another.
To maintain the X-linkage frame in the in-use position, a stay member is provided for rigidly connecting the two linkages together, the stay member conveniently being pivoted at or adjacent one of its ends and being adapted to have a latchtype connection with the other link on the X.
According to a particularly advantageous feature, the stay member has a number of latching positions with a keeper on the frame so that the X-linkage can be secured in various positions (i.e. corresponding to different included angles between the links) to suit the statures of different users.
One of the limbs of the X may comprise two parallel spaced tubes and the other limb may be constituted by a single tube pivoted to and extending between the parallel tubes. The disc of the brake pad assembly may be located so that it extends at least partially between the two parallel tubes and the disc may be flanked on each side by bearing blocks for journalling the pedal cranks and the disc, the bearing blocks conveniently being bolted on respective ones of the parallel tubes.
One embodiment of the invention is illustrated in the accompanying drawings in which: Figure 1 is a perspective view of a cycle-type exerciser according to the invention; Figure 2 is an enlarged side view of the disc brake assembly; and Figure 3 is a view of the disc brake assembly seen in the direction 3 in Figure 2.
As shown, the exercise apparatus comprises an X-linkage frame comprising a single tube 10 and a pair of tubes 12 pivotally interconnected at 1 4.
The tube 10 is provided with a stabiliser foot 1 8 and handlebars 20 whilst the tubes 12 are provided with stabiliser foot 22 and adjustable height saddle 24. The linkage is secured against folding by a stay 26 pivoted at 28 and engageable with a crosspin 30 or the iike. The stay 26 has at least two open ended slots for selective latching engagement with the crosspin 30 whereby the angle of intersection between tube 10 and tubes 1 2 can be adjusted according to requirements.
The tubes 12 mount a pair of pedal cranks 34 which are journalled in plastic bearing blocks 36 clamped to the tubes 12 by brackets 38. The pedal cranks 34 are secured to a disc 40 located between the tubes 1 2 and a pair of friction pads 42 carried by cantilever brackets 43 bear against the opposite faces of the disc 40. An adjuster screw 44 associated with the free ends of the brackets 43 enables the pressure exerted on the disc by the pads 42 to be varied. In this manner, a selectively variable resistance to rotation of the disc 40 thereby allowing the effort required on the part of the user in turning the pedals to be adjusted.
It will be appreciated that a cycle-type exerciser having the above features and in particular employing a disc brake assembly for regulating the effort required on the part of the user is economical to manufacture and comprises relatively few components.
