Definitions
- the present arrangement relates to a ramp according to the preamble of claim 1.
- Ramps with rest surfaces are in most cases a prerequisite for allowing handicapped persons to keep their personal mobility when they are dependent on means of assistance such as a wheel-chair or a walking frame.
- the ramp with the rest surface fully or partly replaces the function of a stair, which for obvious reasons can not be used by people who are dependent on means of assistance of said kind.
- leg arrangements Since the length of each of the legs varies depending on the inclination allowed in relation to the horizontal (normally between plus/minus 10 %), hitherto known leg arrangements implies a maximum inclination of the leg in relation to the vertical of up to 6°.
- a leg arrangement for a slope plate is disclosed in JP 08027982A.

Abstract
Description
- The present arrangement relates to a ramp according to the preamble of
claim 1. - Ramps with rest surfaces are in most cases a prerequisite for allowing handicapped persons to keep their personal mobility when they are dependent on means of assistance such as a wheel-chair or a walking frame. The ramp with the rest surface fully or partly replaces the function of a stair, which for obvious reasons can not be used by people who are dependent on means of assistance of said kind.
- The constructional and functional demands on such equipment are very high, not least because they are first of all to be used by handicapped people. The admissible load in such constructions often has to be compared to the functionality thereof and the latter may many times prevail even if it means that the construction will become overdimensioned. This, however, makes it clumsier and less aesthetically pleasant. Further, there are since some years requirements regarding the possibility of reuse of the equipments when they are no longer needed at a certain location.
- Since the length of each of the legs varies depending on the inclination allowed in relation to the horizontal (normally between plus/
minus 10 %), hitherto known leg arrangements implies a maximum inclination of the leg in relation to the vertical of up to 6°. A leg arrangement for a slope plate is disclosed in JP 08027982A. - Buyers of equipment of this kind are at present mainly municipal administrations and the demand is strongly increasing. This probably depends on the increasing use of home medical assistance. The buyers are then presupposed to buy an equipment which is both safe, simple to assemble and disassemble and which is adaptable to entrances of different kinds. As a consequence of the requirement on adaptability and also of the admissible load requirement, previously known ramps have depending on their length, inclination and use often been provided with legs that have adaptable length. However, depending on the possible height differences of maybe up to one meter, it has been necessary to keep in stock a lot of legs with different lengths and ancillary connection parts.
- In order to be able to keep up a rational manufacture in spite of this, the leg connection has been fixedly arranged and in alignment with the ramp, with the consequence that legs with lengths of up to a meter may incline substantially. This means that it has become necessary to dimension the leg consoles and their attachments also with regard to the varying and partly recurrent pulsating torsion forces occurring at use (dimensioning with regard to fatigue stress).
- Above all, since equipments in the future in many cases will be reused at several places, the risks that leg consoles or attachments sooner or later will fracture during use due to wrong dimensioning increase. Under unfortunate circumstances this may lead to a complete collapse of an equipment, which over all may be very worn. The consequences may be serious, not least to the person, previously handicapped, who may meet with a fall due to a broken leg attachment. The consequences will even if they are not serious, at least be costly to the municipal administration responsible. Demands for damages will probably be raised against those responsible for the security of the equipment.
- The purpose of the present invention is to achieve a leg arrangement of the kind initially described, in which both the basis for the problem with the torsion stress and also the requirements for a fatigue dimensioning will be eliminated.
- According to the invention the arrangement is so built that leg retainers may be attached thereto in an angle which may be freely chosen within limits, whereby the leg of the leg arrangement may be arranged perpendicularly to the horizontal.
- In such cases when the attachment is constituted by a separate console, the console may with the adaptability according to the invention be made much more slender, which will positively effect the impression which an equipment of this kind necessarily gives.
- The use of such consoles gives an extra large width between handrail attachments arranged in the leg arrangement.
- Since a handrail attachment is arranged in connection with the leg attachment, the immediate consequence of the turnability of the console will be that the handrail attachment will coincide with the vertical.
- The leg attachment, the leg, and the handrail attachment, which each may be constituted by square pipes arranged in each other in decreasing dimension, are mutually slidable and fixable in relation to each other in fixed positions which are determined by boltholes penetrating the respective parts. The parts that are mutually fixed lengthwise with said bolt joints, rest on these joints. By the telescopic mutual slidability one single leg length may be used to manage all mounting heights normally occurring.
- The invention will in the following be described with reference to an embodiment shown on the enclosed drawings, in which:
- Fig. 1 shows a schematic view of a ramp with details;
- Fig. 2 shows a view from II-II in Fig. 1 and shows a leg attachment fixed to a ramp and a leg console with an integrated leg/polepipe attached thereto with screws;
- Fig. 3 shows a view from III-III in Fig. 1 of the attachment/console and the leg/polepipe.
-
- Fig. 1 shows schematically a perspective view of a
ramp 1 with arest surface 2 belonging thereto,handrails 3 with attachments and leg arrangements 4. From the encircled portion, which is enlarged, it can be seen how the view according to Figs. 2 and 3, respectively, have been taken. - Fig. 2 shows in approximately full size and more in detail, how a
console 5 is attached with aweld 6 to theramp 1. As can be seen from Fig. 3, theconsole 5 is made up from a U-profile. Anintermediate portion 7, preferably a square pipe, is attached to theconsole 5, using two screw connections 8 (schematically shown with dashed lines). The hole in theconsole 5 for the upper one of thescrew connections 8 is ovally shaped in transverse direction. Said hole is shown as a hidden contour in Fig. 3, where it carries the designation H, is preferably of the dimension 9 x 26 mm. By the oval shape of the hole, the inclination of therespective leg 13 and itshandrail pipe 3 may be adapted (+/- 6°) to the actual inclination of theramp 1. Theintermediate portion 7 is at 10 in turn welded to anattachment pipe 9 of the leg arrangement 4. The attachment pipe is preferably of the dimension (W x H x TH) 40 x 40 x 2 mm. Theintermediate portion 7 and theattachment pipe 9 may together be designated as aleg retainer intermediate portion 7 is, as shown in Fig. 2, obliquely cut at 11, the purpose of which is to achieve a better accessibility, for in turn achieving a simpler mounting of details necessary for each of theconnections 8. - In an alternative embodiment according to the invention, not shown, one of the
screw connections 8 may be replaced by a dowel co-operating with a round hole, around which dowel a turning is possible. - In each
attachment pipe 9, first thehandrail pipe 3 and thereafter aleg pipe 13 are mounted. Thehandrail pipe 3 and theleg pipe 13 preferably are of the dimensions 35 x 35 x 2 mm, and 30 x 30 x 2 mm, respectively. The mutual dimensions of these pipes are such that they have a clearance fit, and consequently may be pushed into and out of each other. - Likewise in an approximately natural size, Fig. 3 shows a leg arrangement according to the invention, partially as a view and partially as a cross-section from III-III of Fig. 1. Here it is more clearly seen how the different joints and pipe portions are mutually arranged. The
pipe portions attachment pipe 9, are mutually fixed with at least two sturdy throughbolt joints 12. Thehandrail pipe 3 has such a length that it goes beyond the lower one of thebolt joints 12.
