Description

TRANSPORT CHAIR DEVICE
The present invention relates to a transport chair device for disabled persons, wherein the chair has a front frame with a front pair of wheels and a rear frame with a rear pair of wheels pivotally mounted therein, a seat frame, a backrest and a footrest.
A great number of transport chairs of this kind, as well as standard wheelchairs, are currently available to disabled persons. A major drawback of these chairs is that they have a complex mechanical structure, are usually heavy because they consist of many metallic parts and are only collapsible to a small extent.
Known chairs of this kind are usually of such a size that they are difficult to manoeuvre in cramped surroundings, such as on board an aircraft.
Moreover, it is a problem with the known chairs that when used at airports all the metal in the chair will be readily registered by security metal detectors, and clearly this complicates the security check when disabled persons are to pass through metal detectors.
Accordingly, it has been an object of the invention to devise a transport chair device for disabled persons, wherein the distinguishing features of the chair are its low weight and its collapsibility, and where metal detectors will not react to the chair.
According to the invention, the device is thus characterised in that the rear frame and the seat frame are made in a single piece, that the front frame is pivotally attached to the seat frame, is capable of being folded in towards the seat frame and the rear frame, and has means for limiting its forward rotational movement relative to the seat frame, that the backrest is height-adjustable and provided at the top with handgrips, and that the front frame, the seat frame and the rear frame, the backrest, the footrest and said pairs of wheels are made of one or more non-metallic materials.
According to one embodiment of the device, at least one wheel brake that is known per se is provided on the front frame for interaction with the front pair of wheels.
According to a second embodiment, the backrest is telescopically attached to a rear portion of the rear frame and/or the seat frame. In one specific embodiment, so as to enable the chair user to operate the chair himself, it will be advantageous to attach to the front portion of the seat frame at least one control wheel which via a transmission, e.g., a drive belt, is designed to actuate at least one of the wheels in the front pair of wheels.
To reduce the weight of the chair, and at the same time prevent the chair from being registered by security metal detectors, the non-metallic materials are selected from the group consisting of: rubber, plastics, composite materials, fibre-reinforced rubber, fibre- reinforced plastic material and fibre-reinforced composite material.
The invention will now be explained in more detail with reference to the attached drawings.
Fig. 1 shows the chair according to the invention in a first embodiment, with a person seated in the chair.
Fig. 2 shows a minor modification of the chair in Fig. 1.
Fig. 3 illustrates the collapsibility of the chair.
Fig. 4 shows how practical the transport chair is in connection with passage through a security metal detector.
Fig. 5 shows how practical the chair is in connection with any visits the user may make to the toilet.
Fig. 6 shows the chair in connection with transport in cramped surroundings.
A regular wheelchair is generally unsuitable for use in connection with transport on board aircraft or in other places where movement is difficult owing to restricted space. Disabled persons will thus have difficulties in moving around unless a smaller and narrower transport chair is available in surroundings of this kind.
The object of the present invention therefore has been to provide a transport chair 1 for a disabled person 2, wherein the chair has a front frame 3 with a front pair of wheels 4 and a rear frame 5 with a rear pair of wheels 6 which are pivotally mounted in the rear frame 5 via a swivel connection 7. Furthermore, the transport chair has a seat frame 8, a backrest 9 and a footrest 10. As can be seen from, inter alia, Fig. 1, the rear frame 5 and the seat frame are made in a single piece. The front frame 3 is pivotally attached to the seat frame 8 via a swivel connection 1 1 and can be folded in towards the seat frame 8 and the rear frame 5, so that the front pair of wheels 4 comes to rest between the front pair of wheels 6 as indicated in Fig. 6. The front frame 3 is provided with means in the form of a strap or link 12 which limits the forward rotational movement of the front frame 3 relative to the seat frame 8. The backrest 9 is height-adjustable and is provided at the top with handgrips 13.
The handgrips 13 are preferably arranged so as to interact with and control a backrest 9 locking mechanism 21. With the handgrips 13 pointing backwards, the backrest is locked due to engagement between the locking mechanism 21 and backrest bars 9', whereas when the handgrips are swung into, e.g., a horizontal position and approximately parallel to the backrest, the backrest can be moved freely up and down, the bars 9' then sliding freely in the locking mechanism 21.
To ensure that the transport chair is not registered by a security metal detector, such as those usually found in airports, the front frame 3, the seat frame 8, the rear frame 5, the backrest 9 and the footrest 10, plus the said pairs of wheels 4, 6, are all made of one or more non-metallic materials. These non-metallic materials may be selected from the group consisting of: rubber, plastics, composite materials, fibre-reinforced rubber, fibre -reinforced plastic material and fibre-reinforced composite material.
Advantageously, at least one wheel brake 14 that is known per se can be provided on the front frame 3.
As can be seen from Figs. 4 and 5 in particular, but also from Fig. 6, the backrest 9 is telescopically attached to a rear portion of the rear frame 5 and/or the seat frame 8 by means of the backrest, e.g., being slidably arranged in a groove 15 on the rear frame and/or seat frame.
In certain cases, especially when the disabled person has full mobility and strength in his arms, it will be both satisfactory and advantageous with respect to the usefulness of the transport chair if there is pivotally attached to the front portion 8' of the seat frame 8 at least one control wheel 16 which via a transmission, e.g., a drive belt 17, is arranged to actuate at least one of the wheels of the front pair of wheels 4. Even with a control wheel of this kind, the transport chair will be easily collapsible, but to be able to place a folded chair in an overhead luggage compartment 18 in the cabin of an aircraft, it will be necessary to remove the control wheel and place it loose together with the chair when it is stowed away on board.
As will also be seen from Fig. 4, the transport chair 1 will be easily transportable through, for instance, a security metal detector 18, and because of its widely spaced rear pair of wheels 6 it can be easily positioned against a toilet, the chair user in such a position pushing the backrest 9 down so as to be able to pull himself backwards towards the seat portion 20 of the actual toilet. This is shown in more detail in Fig. 5.
In Fig. 6 it can be seen that the present chair is easily manoeuvrable, for example, on board an aircraft, whereas it would be very difficult to manoeuvre an ordinary wheelchair in the same way.
