Walking frame

Walking frame description/claims

The invention relates to a walking frame provided with a frame that is supported on a number of wheels and a harness for supporting the user of the walking frame.

Such a walking frame is generally of prior art.

In the walking frame of prior art, the user is generally supported vertically by means of a harness which is secured around his/her chest and is also supported by the frame of the walking frame. This prevents the user from assuming a kind of suspended position and there is no encouragement for the user to move forward or walk.

The object of the invention is to provide a walking frame of the above-mentioned type which encourages the user to walk.

This object is achieved according to the invention in that the harness is connected to the frame by means of a spring system which is orientated so that on the one hand it provides a vertical support for the user and on the other has a horizontal resilience in the direction of forward movement.

Because the spring system not only has the vertical component but also a horizontal component, the user is pushed forward, so to speak, causing the user to be pushed off balance, as it were, and is encouraged to take one step forward. As the user moves forward, this effect is increased.

The spring system preferably consists of a spring which forms an angle of 40 to 50 degrees to the plane of movement of the user.

Other characteristics and advantages will become clear from the following description with reference to the attached drawings. In the drawings:

FIG. 1 shows a perspective view, partially in side elevation and partially as a rear view, of an orthopedic walking frame according to the invention;

FIG. 2 shows a perspective front view of the walking frame shown in FIG. 1; and

FIG. 3 shows a perspective view, partially as a rear view and partially in side elevation, of the walking frame shown in FIG. 1.

The walking frame such as that shown in FIGS. 1-3 comprises a U-shaped, bent tube 1, the surface of which, when the walking frame is in use, extends at an angle of approx. 45° to the surface on which the walking frame is to move. A tube section 2 and 3 respectively is secured to each free end of U-shaped tube 1, which tube section extends almost vertically when the walking frame is in use. A wheel, 4 and 5, is mounted at each tube end 2 and 3 respectively, so that each wheel 4, 5 rotates about a horizontal axis during the forward movement of the walking frame, and the whole of each wheel, consisting of the wheel, shaft and support strap is connected rotatably around a vertical axis to the associated tube section 2, 3.

A tube section 6, 7 is also secured to each leg of U-shaped tube 1. Each tube section 6,7 extends mainly outwards at an angle of approx. 90° to the surface of the U-shaped tube in the upward direction in the normal operating position of the walking frame. Tube sections 6, 7 may possibly be connected to the legs of the U-shaped tube so that this angle is adjustable and so that when the walking frame is in use, the position of the tube sections can be adapted to the user of the walking frame. Handles 8, 9, made for example from rubber or plastic, are fitted to the free ends of tube sections 6, 7, in order to improve and facilitate the grip of the user.

A straight tube 10 is connected to the U-shaped tube near the central point of the bent part of U-shaped tube 1. The connection between tubes 1 and 10 is detachable so that the two tubes can be rotated relative to each other when a clamping mechanism is released, whereas in the fixed position of the clamping mechanism the connection between tubes 1 and 10 is locked. This enables the two sections to be rotated relative to each other so that tube 10 lies in the plane of U-shaped tube 1 and the walking frame is folded up, so to speak. Such a clamping mechanism may be obtained quite simply, for example, by connecting tube 10 rotatably, by means of a bush, to tube 1 and by securing in position, over bush 1, a circular plate which can be connected by a pin or the like to tube 10. For this purpose, holes may be made in the circular plate around its periphery and a corresponding hole made in tube 10. The angle between tubes 1 and 10 can therefore be adjusted, even when the position between the tubes is fixed.

A cross tube 11, which extends horizontally in the normal position of use of the walking frame, is mounted on the lower end of tube 10. A vertically directed tube section 12, 13 is secured to each free end of cross tube 11. The section 12, 13 has a respective wheel assembly 14, 15 mounted thereto. In principle, this wheel assembly is identical to assemblies 4 and 5, except that wheels 14, 15 cannot swivel but are rigid in terms of their orientation.
