An Arrangement for Supporting a Person
The present invention relates to an arrangement for supporting a person when the person is being moved between two locations, this movement being accomplished by means of a lifting arrangement. The main object of the present invention is primarily to provide an arrangement of .the above-mentioned kind which enables the person who is using the arrangement to be effectively carried and supported, for example so they can be moved from a wheelchair to a vehicle, or between a wheelchair and a bath.
The said object is achieved by means of an arrangement according to the present invention which is essentially characterised in that acoupling element, on which a supporting element co-acting with the back of the person is mounted, extends from a centrally positioned frame on which supporting elements for supporting the person under their seat and armpits are mounted.
The invention is described in the following by way of a preferred embodiment example of a supporting arrangement, with reference to the accompanying drawings, on which
Figure 1 shows the arrangement in use, supporting a person,
Figure 2 shows the supporting arrangement with an associated lifting arrangement which can be coupled to it, in a position viewed obliquely from behind the said supporting arrangement,
Figure 3 shows the said lifting arrangement swung into a closed state,
Figure 4 shows the supporting arrangement viewed obliquely from behind, and
Figure 5 shows the supporting arrangement viewed obliquely from the front.
A supporting arrangement 1 according to the present invention, which is suitable for supporting a person 2
whom it is intended to move between two locations, for example from a wheelchair to a vehicle, is formed of a centrally positioned frame 3 on which there are mounted two supporting elements 4 and 5 respectively, designed to carry and support a person 2 under the armpits 6 and 7 respectively, together with a supporting element 8, designed to co-act with the seat 9 of the person and to support the said seat 9, and a supporting element 11 co- acting with the back 10 of the person. Expediently, .the frame 3 is made in the shape of a T, having at its lower end 3A a section 12 extending forwards, away from the back supporting element 11, followed by a section 13 extending laterally from the section 12. Due to the fact that the frame 3 and the other parts incorporated in the support- ing arrangement 1 consist of tubes or similar elements, simple production and assembly of the arrangement 1 and rapid adjustment of the supporting elements 4, 5, 8, 11 to various settings are possible.
A coupling element 14 consists of a downwardly from the said frame 3 extending upright 14 with an arm element 142 extending backwards in the vicinity of its lower end
14A, the rear end 14B of this arm element being bent laterally in towards the region for holding a person 2 and bearing a supporting element 11 there which co-acts with the back 10 of the person and which can be shaped to fit the contours of the back 10. The upright 14 engages via a sleeve-like coupling part 15 round the said arm element 142 and by means of a locking device 16 acting between the said coupling part 15 and the arm "element 14 displacement of the arm element 14 relative to the upright 14 is possible into the desired position wherein they are locked relative to each other by means of the said locking device. In the embodiment example shown the said locking device 16 consists of a screw 16, but naturally a locking device other than a screw is also possible.
One 5 of the two armpit supporting elements 4 and 5 respectively is preferably rigidly connected to the coupling element 14 in the vicinity of its upper end 140. In order to protect the person 2 from injury or from suffering discomfort when using the arrangement 1 the said supporting elements 4, 5, 8, 11 are made of soft material, and are preferably stuffed elements, for example bar- shaped cushions, etc.
Adjustment of the other one of the supporting elements 4 and 5 and optionally the supporting element 8 as well is possible in that the respective ends of the frame 3 have openings 17, 18, 19 designed to receive connecting elements 20, 14, 21 which are connected to the supporting elements 4, 5, 8, and can be locked in the desired position by means of locking devices 22, 23, preferably also in the form of screw devices.
An attachment device 24, preferably in the form of a coupling of the quick-coupling type, is connected to the frame 3 in the vicinity of its upυer central part 3B be2 3 tween the two laterally extending arms 3 , 3 which extend in opposite directions from the substantially ver1 tical frame part 3 . The said attachment device 24 which is formed, for example, of a coupling element with a hole through it, is designed to allow simple and quick coupling and uncoupling of the arrangement 1 with and from a lifting arrangement 25 which is designed for moving the said arrangement 1 and the person 2 supported on it between the desired locations.
A lifting arrangement 25 which is suitable for moving the said supporting arrangement 1 is shown on the drawings in Figures 2 and 3 and partly in Figure 1, and consists of an outer and an inner pivot arm 26 and 27 respectively, which are pivotably mounted on each other via an articulation 29 connected to a drive motor 28. The inner pivot arm 27 is mounted so that it can pivot around a substantially horizontal axis 30 which is located at the upper
end 31A of a column-like upright 31 which may be rigidly connected to a wall, a vehicle, etc., and which can expediently be rotated around its central axis 32. An actuating arrangement 33 in the form of an extensible and retractable arm, preferably telescopic, extends between the upright 31 and the said inner pivot arm 27 and is actuated expediently by a similar disc motor 34 as the motor 28 which acts between the arms 26, 27. A terminal position stop device is expediently mounted on the said actuating arrangement 33, for example in the form of a rod 35 which extends along the arm 33 and is guided by a guide element 36 connected to the arm 33. The outer end 26A of the outer arm 26 bears a connecting element 37, for example in the form of a pin 37, which can co-act with the said attachment device 24 disposed on the supporting arrangement 1.
The two motors 28, 34 are expediently connected to a manually-operated remote control device (not shown on the drawings) for the lifting arrangement 25, enabling the person 2 whom it is intended to move by means thereof via the supporting arrangement 1 to operate the lifting arrangement themselves and to control its movements.
The functioning of the arrangement described above may be as follows: After having expediently released the screw 23, the coupling element 14 is pulled out with its associated separate supporting element 5 co-acting with the armpit and the supporting element 11, making it possible for the person 2 who desires to use the supporting arrangement 1 to introduce the supporting element 8 under his or her thigh and seat 9, and to introduce the supporting element 4 under one armpit 6, and to adjust it to the desired position, for example when the person 2 is sitting in a wheelchair. After this, the coupling element 14 is pushed into the frame arm part 3 and is locked by means of the screw 23 in the desired position. At this
time, the second supporting element 5 which is designed to co-act with the other armpit 7 of the person and the supporting element 11 for the back 10 are adjusted by means of the screws 23 and 16 respectively. After connecting the arrangement 1 to the lifting arrangement 25 via the attachment devices 24 and 37 it is possible to lift the arrangement 1 and the person 2 supported thereon and to pivot them into the desired position by operating the drive motors 28, 34. The person sits comfortably and securely supported by the said arrangement 1 and it is also possible for the person 2 to remain sitting in the arrangement 1 for subsequent moving, after the arrangement 1 has been uncoupled from the lifting arrangement 25. The invention is not limited to the embodiment example shown on the drawings and described above, but may be modified within the framework of the following Patent Claims.
