Abstract
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, whereby that the harness is connected to the frame by a spring system which is orientated so that on the one hand it provides vertical support for the user, and on the other exerts a horizontal spring action in the forward direction of movement.
Description
- 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 inFIG. 1 ; and -
FIG. 3 shows a perspective view, partially as a rear view and partially in side elevation, of the walking frame shown inFIG. 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. Atube section tube 1, which tube section extends almost vertically when the walking frame is in use. A wheel, 4 and 5, is mounted at eachtube end wheel associated tube section - A
tube section U-shaped tube 1. Eachtube section Tube sections tube sections - A
straight tube 10 is connected to the U-shaped tube near the central point of the bent part of U-shapedtube 1. The connection betweentubes tubes tube 10 lies in the plane of U-shapedtube 1 and the walking frame is folded up, so to speak. Such a clamping mechanism may be obtained quite simply, for example, by connectingtube 10 rotatably, by means of a bush, totube 1 and by securing in position, overbush 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 intube 10. The angle betweentubes - A
cross tube 11, which extends horizontally in the normal position of use of the walking frame, is mounted on the lower end oftube 10. A vertically directedtube section cross tube 11. Thesection respective wheel assembly wheels - A
brake lever 16 is secured near the top oftube 10. The brake lever is connected by a cable to a braking mechanism of prior art onwheels wheels - A
rod 20, which rests with its lower end on a spring, not shown, fitted insidetube 10, is inserted intube 10. To ensure thatrod 20 is guided correctly insidetube 10, the inside of the top section of the tube is provided with rollers to form an axial bearing, so to speak, forrod 20. Means are fitted near the bottom oftube 10 for adjusting the force of the spring. This enables the resilience of the spring to be adapted to the weight and capabilities of the user. The spring can be a conventional helical spring, but otherwise pneumatic of hydraulic springs may be used as well. - The top of the rod is hinged to a
plate 21, which is, in turn, again connected to aharness 22 of flexible material.Harness 22 consists of a U-shaped section provided with straps so that a user can be secured inharness 22, as generally known in the care of handicapped or spastic patients. The support strap may also possibly be provided with fastening mechanisms for support mechanisms for the lower limbs of the user. - In case improved stability is required, it is possible to add another tube parallel to
tube 10 and connected thereto and another rod parallel torod 20 and connected thereto. By this parallel guiding system, improved stability can be obtained. - The use of the walking frame according to the invention is intrinsically clear. After the user is secured in
harness 22 of the walking frame he or she may or may not be assisted by a third person to take his or her first steps. During these steps, the spring will always be compressed for part of each step, and will then retract. This gives the user the feeling of being supported so that he or she gains more confidence in moving, whilst at the same time he or she receives a push in the back which brings him or her off balance, encouraging him or her to take the next step to recover his or her balance. The process is then repeated. - Experiments with subjects with spastic abnormalities have demonstrated that after a short introductory and practice period, they are able to move independently without problem after being secured in the walking frame, and are free to choose the direction of their movements.
- It is clear that the invention is not limited to the embodiment described and reproduced but that numerous modifications can be made within the scope of the claim.
