FR2740677A1 - Walking frame for handicapped user - Google Patents

Abstract

The walking frame (A,B) has a rigid seat with a foam padding (6) which has a raised back to reduce muscular fatigue. The rollers(5) allow a displacement in all six planes in space. A hinge (3) and a screw (4) allows a complete lateral opening of the frame for access. There is a removable panel (7) and a manual brake. In an seating position, some of the rear rollers can auto-lock.

Description

The i invention is a walking frame on wheels for the elderly or disabled It
allows faster recovery of autonomy thanks to frequent, daily use, It can be
the only way a person can get around without any risk of falling
So far, there are different walking aids These devices are not very stable or heavy, difficult to use and not very reassuring for the user
The invention, set out here, overcomes these drawbacks
It is a walking device mounted on casters, which opens laterally thanks to a charmère. It allows
to settle in easily. Once closed, the subject stands up and adjusts the height alone or assisted. Walking becomes
active and reassuring The subject cools down when tired.

According to the particular embodiments:
A manual brake, wheelchair type, can be provided allowing greater stability during
transfers.

 The height adjustment is mechanical thanks to 2 cranks placed close to the hands.

This system can be improved by an electrical system thanks to a small motor and a battery
rechargeable (in the latter case, the mechanical system is kept to compensate for any battery failure)
The subject is walking while trotting. This pressure cannot block the rollers. More support is needed
supported only on the back so that the device comes out immobilized
In the event of a posterior fall, the patient is in a seated position, the fall is only a few centimeters and the device is stabilized zutomatically
The invention is thus made up.

 - A rigid tube (A) constitutes the lower frame. It is bent and square in shape. It is covered with PVC.

(see figure 1 top view)
n is formed by a posterior part (I) and an anterior part (2)
n is article by a hinge (3)
It closes with a small lock (4)
H rests on 6 mules (5).

 Figure l shows the bottom frame closed and then opened.

 - A rigid tube (B) similar to the lower tube constitutes the upper frame. From this frame hangs a molded PVC seat (6). A removable PVC shelf (7) fits by simple pressure on the tube frame (Figure 2 side view).

- The upper and lower frames (A and B) are interconnected by 6 tubes
- on the posterior part (1)
- 2 oblique tubes (8 and 9) sliding on the left of the device, which are articulated between them
their love center of an axis thanks to a screw (figure 2 left profile view).

 - 2 oblique tubes (8 'and 9') sliding at right angles to the device, which are articulated between them in their middle around an axis thanks to a screw.

- on the front part (2)
- 2 vertical tubes (10 etlO ') sliding allowing to join parts A and B.

 The axis allows to adjust the height of the trot in fbiction of the length of the lower limbs.

 The vertical axis presses down through the middle of the body. fi may be slightly anteriorized (Figure 2).

The seat (6) is in molded PVC
- It is compost from a baut file. This avoids a muscular fig of the back during the station
extended sitting.

- n is made up of 2 joined parts which fit together when the device is closed. The 2 parts
are disjoined during the installation of the subject (figure 3 upper view).

- n is covered with foam and washable plastic film see anti-decubitus gel for sink
any buttock irritation
The height is adjusted, subject in standing position, by manual rotation of one of the 2 cranks placed on the right and on the left on the upper frame (11 and îl figure 2) Cctte rotation close or Heals the 2 points C and D and E and F simultaneously.

 C and E are fixed, D and F are mobile. There is sliding of the oblique tubes.

 To allow simultaneous sliding on the right and on the left, a system of worm and gears is concealed in the upper frame (B).

The use of the invention is the survivor
The device is positioned in the low position, brakes set (12), perpendicular to a chair, an armchair or the bed and at the same height. It is widely open
Alone or helped, the panent Sits there
Once positioned, it closes the antericure part and locks.

 The subject verficalizes as much as possible, the blades of axes and knees are taken into consideration. The height of the trot is adjusted so that the pubis is less than 5 cm from the lower part of the seat.

The subject wanders by pressing partially on the front
In the event of fatigue, the passage to the sitting position proves to be your Se and not very constraining
In the event of imbalance, the subject finds himself in a sitting position without being frightened. He has only 5 cm to travel and the device stops automatically.

In the electrical embodiment
The control is electric and is done by manual pressure on a button.

By way of nonlimiting example, the walking frame will have dimensions of the order of 55 cm wide, 55 cm deep, 90 cm high
n exist 2 or 3 different sizes depending on the size of the subject
At a time when the population is increasingly aging, this mvention is particularly intended for the elderly or disabled with motor or cerebral disorders. It will have a special place in retirement homes, convalescent homes, rehabilitation centers and why not at home.
