Abstract

A wheel chair (1) is secured in a vehicle, like a minibus, the wheel chair being provided with fittings (3) with engaging means, which can engage and be fixed by jaws in two sets of jaws on a device (4) mounted on the base (2) of the bus. The engaging means on the fittings (3) and the openings between the jaws are designed with cross sections, which generally do not vary in the direction of travel (11) of the wheel chair. Thus the engaging means on the fittings (3) can be engaged in the sets of jaws by advancing the wheel chair in the directon of travel (11). The set of jaws are mutually spaced crosswise to the direction of travel (11), and the fittings (3) are designed to being fastened mutually spaced apart in pairs on the wheel chair (1) near the areas where the wheels (8), which carry the greatest weight load of the wheel chair (1), are mounted to the chair (1). Thus a strong and safe securing of the chair to the base (2) of the bus is obtained, the fittings (3) and the device (4) also being suitable for use with a collapsible wheel chair.

Description

in DK PR 172482 B1

The invention relates to an apparatus for holding a wheelchair and a bracket for mounting on a wheelchair; the apparatus is of the kind specified in the preamble of claim 1, and the bracket is of the kind stated in the preamble of claim 11.

Such appliances and fittings are used in particular for attaching wheelchairs to cars and buses, so that wheelchair users can use these means of transport without having to leave the wheelchair.

10 From the publication: Council for technical measures for disabled people: "Seats, belts and wheelchairs", NKH / ISO no. 12 12 09, 12 12 12, 12 12 24, 1992, Center for Industrial Research, Oslo, several appliances and a fitting are known of the species mentioned initially.

The apparatus may be attached to a substrate such as a single car floor, corresponding to the apparatus formed brackets or to floor rails mounted in the substrate. Such floor rails are known in several designs, for securing seats 1 buses and airplanes and for securing loads in airplanes and cargo containers. They often take the form of a recessed rail with a longitudinal, upwardly open T-shaped groove, which at regular intervals has openings in the full width of the groove, so that bolts with a T-shaped head can be lowered and received through the openings.

25 On page 05-07-01.0 of the said publication, an apparatus of the kind mentioned above is described, in the form of a set of harnesses with associated floor brackets, where the wheelchair is fastened to the support by means of the harnesses, while supporting on its own wheels. The belts are hereby directed from points 30 on the wheelchair frame and inclined outwards and downwards. No adjustment of the wheelchair is required. The device is manufactured by Gustav Bruns GmbH & Co KG, Apen (DE).

Sheet 05-07-19.0 describes a similar device in the form of a set of braces for fastening in floor rails. The harnesses are provided at the end facing the support with claws which are inserted into the floor rails, where they are held in place by displacing a piece in the pulling direction of the harness. Nor does DK PR 172482 B1 2 require adjustment of the wheelchair. The apparatus is manufactured by C. N. Unwin, Ltd., Somerset (GB).

Sheet 05-07-18.0 describes an apparatus of the kind mentioned above, in the form of two toothpicks with each two 5 claws, which can grip a floor rail and about part of the wheelchair frame respectively. The claws can be tightened in a direction towards each other, with a paw in the upper claw interacting with the teeth of the rod. With the rods, the wheelchair is tensioned against the ground, while supporting on its own wheels. The rods are hereby substantially vertical and exert their force in this direction. The device does not require adjustment of the wheelchair and is manufactured by C. N. Unwin, Ltd., Somerset (GB).

On leaf 05-07-17.0 a similar apparatus is described in which the rods are designed with threads and the claws are tightened in 15 direction against each other with this thread. The lower claw of the appliance can interact with floor rails or separate floor brackets. The device does not require adjustment of the wheelchair and is manufactured by SN Konsult, Gåvie (SE).

Sheet 05-07-03.0 describes an apparatus and bracket 20 of the species mentioned at the outset. The apparatus comprises a set of two upper and two lower claws and is attached to the base. The lower claws are fixed and the upper claws are movable by means of an electric motor. The bracket must be fitted with a bracket belonging to the appliance in the form of a bracket, which the claws can grip, thereby holding the wheelchair. The device is manufactured by Handi-Norge AS,

Skjetten (NO).

It is a disadvantage of the appliances that do not require adjustment of the wheelchair that it is only maintained by being influenced by downward or inclined downward forces, whereby the wheel of the chair must provide the necessary reaction.

Especially with the devices where the wheelchair is held with largely vertical bars, the wheel of the chair is disproportionately strained. This is a natural consequence of the geometric conditions in which the horizontal forces that the wheelchair is affected with while driving with the car or bus are transformed into even very large forces in the direction of the rods. There are examples of the wheels of the wheelchair being evenly broken under the influence of these forces, and exede or oval wheels are common injuries. Wheel damage also occurs to a certain extent by clamping with 5 harnesses.

Of course, it is important that the wheelchair is gripped by the restraint where it is strong and stable. In this connection, it is a very significant disadvantage of the appliances that do not require adjustment of the wheelchair, 10 that it is left to the operating staff to decide how to place the belts or the claws of the wheelchairs on the wheelchair frame, in the sense that the design of the appliances does not dictate placement in certain places of the chair. Thus, on certain types of wheelchairs, the claws of said rods may be placed on or at the axes of the rear wheels of the chair, which has the very dangerous effect of the chair being substantially free to tilt backwards about the axis, whereby the wheelchair user's head hits the floor with large power. In the case of collapsible wheelchairs, the impact of the frame at certain locations can affect the chair for collapsing, and other wheelchairs have removable parts such as armrests that are not sufficiently firmly attached to the chair to safely serve to clamp with claws or harnesses.

It is a significant disadvantage of holding with 25 harnesses or rods that the appliances cannot be operated by the wheelchair user himself. Finally, restraint with harnesses or rods is at best cumbersome and time consuming for the operating staff, which often has the tedious effect that the wheelchair will not be securely fastened, or that bus companies or taxi drivers do not want to drive with restrained wheelchairs.

The invention provides an apparatus and fittings of the species mentioned above, which do not have the disadvantages described above, which are particularly well suited for holding collapsible wheelchairs which are very easy to operate for a helper and can be operated by the wheelchair user even where the wheelchair wheels must not transmit any significant reaction resulting from the restraint of the chair, and where the restraint forces are transferred to the wheelchair frame in the most appropriate manner.

This is achieved according to the invention by the features shown in the characterizing parts of claim 1 and claim 11.

5 As the apparatus by means of two jaw sets spaced transversely of the driving direction of the wheelchair clamps brackets which are fixed in pairs on the wheelchair at its wheel suspension, while the jaws and the engagement parts of the brackets are formed with cross sections which do not vary in the direction of movement of the wheelchair. , there is a very efficient transfer of forces and moments from the substrate via the apparatus and fittings to the most solid parts of the wheelchair frame, for both collapsible and non-collapsible wheelchairs. At the same time, the said design of 15 opening cross sections and engagement grooves is achieved that the fittings can be brought into engagement with the jaws by simply advancing the wheelchair 1 in its direction of travel, either forwards or backwards.

In accordance with claim 2, it is achieved that the wheelchair can be conveyed for engagement with the apparatus from both ends of the apparatus, and that the wheelchair can be conveyed through the apparatus, 1 Engagement therewith, and further to or from another similar apparatus.

In accordance with claim 3, it is achieved that the apparatus is particularly well suited for holding wheelchairs which are collapsible in the generally known manner, in which the two side parts of the wheelchair are not folded together in themselves but approached to each other without changing shape.

The claim of claim 4 provides assurance that the wheelchair wheels are not further loaded during restraint, so that as much of the weight of the wheelchair and user as possible is transmitted through the force and torque transfer clamping of the fittings in the jaws of the apparatus.

35 In accordance with claim 5, an improved torque transfer from the apparatus to the fittings is obtained and the possibility of obtaining sufficient strength of the jaws with minimum construction height for the apparatus, thereby minimizing the inconvenience to traffic on the substrate when No wheelchair is attached 1 it.

The claim 1 provides for the possibility of co-operation between the upper jaws of the apparatus and the wheels of the bracket according to claim 15, as well as a simple and inexpensive design of the upper jaws of the apparatus with good opportunity for safe engagement.

According to claim 7, an advantageous force gain is obtained from the activating force moving the lower movable jaw to the squeezing force acting on the fittings, at the same time as a design of the jaw sets which presents a reduced risk of undesirable jamming of persons. or other.

It is achieved in accordance with claim 8 that it is easier for the wheelchair user and driver respectively to convey the wheelchair to the correct engagement of the fittings in the apparatus.

According to claim 9, it is achieved partly that the middle wheel of a three wheeled wheelchair can comfortably pass over the apparatus and partly that an ordinary wheelchair can be passed over the apparatus with its one wheel pair.

In accordance with claim 10, a simple and cost-effective design of guide members and roadway is obtained, while at the same time minimizing the inconvenience to traffic on the ground.

In the case of claims 12 and 13, a special 25 solid and advantageous fastening of the bracket to the wheelchair frame is obtained.

In accordance with claim 14, it is possible to conveniently disassemble the lower parts of the bracket when the wheelchair is not to be retained, while at the same time it can be used universally for all types of wheelchairs, with a special design for each type of wheelchair. the upper parts of the bracket.

In accordance with claim 15, an increased security of correct engagement between apparatus and brackets is achieved and the wheelchair, when secured with the apparatus according to claim 6, can be conveniently conveyed for correct engagement with the apparatus, even if it is completely or partially punctured.

DK PR 172482 B1 6

According to the claim 16, similar advantages as mentioned for claim 5 are obtained, as well as a simple and inexpensive design of the engagement parts with good opportunity for safe intervention.

The invention will now be explained in more detail by means of exemplary embodiments with reference to the drawing, in which: FIG. Figure 1 shows a wheelchair secured in a minibus with the apparatus and bracket according to the invention; 2 is a plan view of an apparatus according to the invention; FIG. 3 corresponds to FIG. 2, removing the enclosure of the apparatus and the upper jaws of the chisels; fig. 4 shows a vertical section 1 of the apparatus according to the invention, taken along line IV-IV in FIG. 2 and with the movable jaws in an open position; 5 shows a corresponding section in the apparatus according to the invention, along the line V-V in fig. 2 and with the movable jaws in a closed position; FIG. 6 is a side view of an upper portion of the bracket 20 of the invention, seen from the outside, FIG. 7 corresponds to FIG. 6, showing the upper part seen in the direction VII in FIG. 6, FIG. 8 is a side view of a lower part of the bracket according to the invention, seen from the inside, and FIG. 9 shows a vertical section in the lower section along line IX-IX in FIG. 8, and also the engagement with a jaw set in the apparatus according to the invention.

In FIG. 1, a wheelchair 1 is shown, which is secured to the floor 2 in a minibus or van. In the figure, parts of the 30 wheelchair base are omitted for the sake of clarity. On the wheelchair 1 are mounted two brackets 3, which are in power-transmitting connection with the shafts 7 to each of the wheels 8 of the wheelchair, which carry most of its weight, here the rear wheel of the chair.

35 On the floor 2 is mounted an apparatus 4 which firmly holds the fittings 3 and thus the wheelchair 1. The apparatus 4 is designed with a low building height, and is provided with an enclosure 9 with rounded shapes, to work as little as possible DK PR 172482 B1 7 bothersome on floor 2 traffic when no wheelchair is held in the appliance.

On the upper side of the apparatus 4 there is a flat portion 6 which is completed along both sides 12 of the apparatus 1 jaws 5 which can grip and hold the fittings 3. The jaws and the cooperating parts of the fittings 3 have uniform cross-section 1 direction parallel to the central part of the apparatus 4 longitudinal axis 10 in the plane of the portion 6, and is designed to be brought in and out of engagement by advancing the wheelchair in its direction of travel 11, hereinafter referred to as the direction of insertion, or the opposite direction. The insertion direction 11 is parallel to the central longitudinal axis 10 of the apparatus 4.

When the wheelchair 1 is brought forward to engage the brackets 3 in the jaws, these are moved towards each other, and the clamps 3 thereby clamp the brackets 3 and thus the wheelchair 1.

On the upper side of the apparatus, there are also inclined portions 5 along the center axis 10, intended to act as ascents and descents, when a wheelchair is to be moved over the apparatus 4 without being engaged with it. Along with the portion 20, the portions 5 form a lane across the apparatus along its longitudinal axis 10. Hereby, one wheel pair 13 of the wheelchair can roll over the lane 5, 6, while the other wheel pair rolls beside the apparatus. However, the wheelchair 1 can also be advanced through the apparatus 4, whereby the brackets 3 are brought into engagement with the jaws of the apparatus and out of engagement again. Both options are useful, for example, when multiple appliances are arranged one after the other for holding multiple wheelchairs, a wheelchair being conveyed over or through the first appliances for a further advancing apparatus.

The apparatus 4 may be attached to the floor 2 with clamping means such as quick-release tensioners which can easily be loosened and tightened, such that the apparatus can, for example, be removed and strapped to the wall of the bus or carriage when the bus or carriage is not to be used for transporting wheelchairs. .

Referring to FIG. 2-5. On the upper side of the apparatus 4, bolts 25 are fastened with a plate 6, which is folded by the sides of the apparatus DK 12 to form upper stationary jaws 15, each comprising a downward flange. These upper jaws together with lower movable jaws 18 form two jaw sets 26. The jaw sets extend 1 direction parallel to the longitudinal axis 10 of the apparatus, and in this direction have an extension corresponding to the extension of the plate 6, cf.

With this extension in the longitudinal direction, the upper jaws 15 can be formed with a very low height, cf. Figs. 4-5, without becoming too weak, and they thereby become decisive for reducing the building height of the apparatus.

The lower jaws 18 are formed with an upwardly sloping face 19, thereby providing a wedge-shaped cross section, see Fig. 5. The lower jaws 18 are movable in the direction 29, being guided in this direction by guide 31-34 which cooperates. with the faces of 15 jaws 18. The jaws are formed with slots 30 in the direction 29. The bolts 25 pass through these slots 30, thereby forming stops which limit the movement of the jaws 18 in the direction 29. With this design, the lower jaws 18 also contribute to the low building height of the apparatus 4.

An actuator 22, known per se, which may be of any suitable type, is secured to the base plate 35 of the apparatus 4 by a bolt 31. The actuator has a extendable rod 27 which moves back and forth in the direction 28 when the actuator work. The rod 27 is connected by a bolt 32 to a carriage 21 which is guided in the direction 28 by guides not shown. To the carriage are hinged at their first end four rods 20, which are hinged at their other end to the lower movable jaws 18. As the actuator 22 operates, the carriage 21 is brought in the actuator's motion and the first ends of the rods 20 are moved with the carriage. in the direction 28, the other ends of the rods move the jaws 18 in the direction 29.

The actuator 22 may according to the invention be provided with a force-sensitive triggering device which stops the actuator when it encounters a resistance of a certain size. Thus, the wheelchair is retained with a desired force, regardless of the thickness, etc. of the fittings 3, while at the same time unnecessary straining and wear on the jaws, etc. avoided.

DK PR 172482 B1 9 In fig. 4, one jaw set 26 is shown in its open state, the lower movable jaw 18 being fully retracted (to the left in Fig. 4). The corresponding positions of the rods 20 and the carriage 21 are indicated in the figure by a 5 dotted line, these parts being shown out of their plane here. In FIG. 5, the jaw set 26 is similarly shown in its closed state, the lower movable jaw 18 being pushed forward (to the right in Fig. 5). It can be seen from FIG. 4 that the opening 17 into which the bracket 3 is to be inserted is relatively small and that the jaw 15 is relatively unobtrusive in relation to the external shape of the apparatus, and therefore to the least possible nuisance when traveling on the floor 2. The apparatus 4 is similar to FIG. 4 and 5, cross sections corresponding to the entire length of the jaws 15 and 18, cf. 2 and 3.

15 When clamped, the wheelchair 1 is raised as a result of the upper jaws 18 of the lower jaws pushing the brackets 3 upwards. This effectively avoids straining the wheelchair's wheels due to the attachment with the apparatus 4 and the brackets 3. Not only does this result in a greatly reduced risk of damage to the wheelchair's wheels, but also a more secure holding of the wheelchair, with a larger part of the restraint force is transmitted through the connection between the apparatus 4 and the fittings 3, which connection is inelastic, while the connection between the wheelchair wheels and the floor is elastic because the wheels have air rubber rings.

The distance between the jaw sets, measured in a horizontal direction, perpendicular to the longitudinal axis of the apparatus 4, corresponds to at least 60% and preferably 70-85% of the wheelchair's track width.

This results in the fact that the brackets 3 must be positioned 1 at a distance such that they can be conveniently fastened close to the wheelchair or axles 7 of the wheelchair, whereby the fastening can be solid and secure. Furthermore, it is achieved that the fittings 3 can thereby be fastened to a collapsible wheelchair of the common type, outside the space which "disappears" upon the folding of the chair, whereby the fittings 3 will not interfere with the folding.

It is important to ensure that persons or objects cannot be squeezed as best as possible when the actuator 22 moves the jaw set 26 together as this is done with considerable force. This is achieved by the very low opening 23 between the jaws, 1 which persons or objects can get into the clamp (see Fig. 4). At the same time, the proper movement of the jaws 18 ensures that foreign objects are pushed out of the opening 23, 24 as far as possible when the jaws are closed (see figure 5).

The enclosure 9 of the apparatus 4 (see following 2) is 1 horizontal plane formed with largely circular arc-shaped edges 36, having a radius slightly larger than the width of the apparatus and 10 corresponding to the wheelchair's track width. This facilitates ranking with the wheelchair when it is to be brought into engagement with the brackets 3 1 the jaw sets 26, since one wheel of the wheelchair will then typically move outside of a circle stroke with said radius. The enclosure 9 is also formed with inlet portions 16, 15 which act as guide members for the fittings 3 when the wheelchair is conveyed for engagement of the fittings 3 in the jaws 26. These measures together provide substantial relief for the wheelchair driver, and also enable the wheelchair 1 to be brought into engagement. of the brackets 3 in the jaw sets 26 of the 20 wheelchair user himself. Therefore, if the controls (not shown) for operating the apparatus 4 are placed within easy reach of the wheelchair user, the apparatus and fittings according to the invention can therefore be used by the wheelchair user for self-service.

In FIG. 6-9, a bracket 3 is shown for mounting on a wheelchair, which bracket can be retained in the jaw kit 26 of the apparatus 4. The bracket 3 consists of an upper portion 37 shown in Figures 6 and 7 and a lower portion 38 which is shown in FIG. 8 and 9. The bracket 3 is intended to be used in pairs, with one upper part 37 and one lower part 38 being used on each side of the wheelchair.

The upper portion 37 can be individually designed for each type of wheelchair, and may conveniently be manufactured and supplied by the wheelchair manufacturer. The lower portion 38 comprises the engaging portions 39 which cooperate with the apparatus 4 and may conveniently be manufactured and supplied by the manufacturer of the apparatus 4. Hereby, the interface between the upper portion 37 and the lower portion 38 becomes a kind of interface between the responsibility DK PR The lower part 38 can be manufactured as a standard part.

An exemplary embodiment of the upper part 37 of the bracket 3, adapted here to be fitted to a particular known type of wheelchair (not shown), is shown in Figures 6 and 7. 1 a fastening portion 43 at the top of the upper part 37 comprises in this case a circular hole 44 and two circular lugs 45. The wheelchair wheel 8 (cf. Fig. 1) is in this case formed with stationary shafts 7, which can be fixed in horizontally extending circular bushes in the wheelchair frame. In the frame of the wheelchair there are a number of holes perpendicular to each other, designed for each bushing to be mounted in one of these holes, depending on the height desired on the chair. The bushings are each provided with an external thread with an associated nut, 15 as well as an outward collar at one end.

The upper part 37 of the bracket is secured to this type of wheelchair by engaging the two lugs 45 with each of said holes in the wheelchair frame, and the bushing is mounted in an intermediate hole, as it is inserted through the hole 44 in the upper part, thereby holding it with its collar when the nut is tightened. Finally, the shaft 7 of the wheel 8 is mounted in the bushing. The bracket is thus firmly and securely attached to the wheelchair frame.

The lower part 38 of the bracket 3 consists of a generally triangular, plate-shaped body 41. On the lower part 38 there are engaging portions 39 which are designed to be clamped in the jaw set 26 of the apparatus 4. 8 and 9 form a horizontally extending, plate-shaped portion 40 with an upwardly directed flange 42, both of which are elongated in the feed direction 11 (which in FIG. 9 extends toward the plane of the paper, perpendicular thereto). Since the cross-section of the engagement particles (see Fig. 9) does not vary in the direction of insertion, they can be inserted into the opening 17 between the jaws 15, 18 in the jaw set 26, 35 of the apparatus 4 by advancing the wheelchair 1 in the direction of insertion 11.

The lower part 38 can be releasably fastened to the upper part 37. This can conveniently be removed when the wheelchair is not to be held in place with the apparatus 4, and the wheelchair is not loaded with the additional weight as the lower part. 38 represents, just like the appearance of the wheelchair, is not ashamed of the relatively bulky lower part 38.

A circular piece 46 can be attached to the fastening at the bottom of the upper part 37, which can be formed with a bevel as shown in FIG. 6 and 7. This piece 46 fits into a circular hole 48 in the lower portion 38. Further, a bracket 47 with a downwardly extending flange 49 behind which a 10 cavity is located, is further upwardly mounted on the upper portion 37. arranged a cam 50 having the shape of half a circular cylinder with horizontal axis of symmetry.

In the upper edge 53 of the body 41 of the lower part 38 there is a recess 52 corresponding to this cam 50. In attaching the lower part 38 to the upper part 37, the recess 52 is engaged with the cam 50, the upper edge 53 engages behind the flange 49, after which the lower portion is tilted, Until the chip 46 fills the hole 48. A slip hook 54, pivotally mounted on a shaft 56 and loaded by a spring not shown, thereby engages the lower 20 edge 57 of the upper part 37 of the bracket 3. Hereby the two parts 37, 38 of the bracket 3 are attached to each other.

The lower portion 38 is released from the attachment to the upper portion 37 by actuating the lever grip 55, after which the lower portion 38 can be pivoted freely.

On the lower portion 38, one or two wheels 58 may be arranged which, upon insertion of the engaging portions 39, 42 between the jaws 15, 18, may roll on the surfaces 6 of the upper jaws 15. This provides a control of the wheelchair 1 in a vertical direction, which control facilitates correct engagement of the engagement portions 39, 42 between the jaws 15, 18. This control is particularly useful if one of the wheels 8 of the wheelchair is pumped less hard or even punctured.

Apparatus 4 and Bracket 3 According to the invention, 35 is not limited to the holding of wheelchairs in means of transport, but can be used for holding wheelchairs wherever this is desired, for example in amusement appliances in amusement parks and the like.
