Device for attaching a rollator to a vehicle such as a mobility scooter

Abstract

Device (1) for attaching a rollator, comprising a frame and wheels, to a vehicle such as a mobility scooter. The device comprises a support frame (2) connected to the vehicle, a wheel catcher (4) to catch one of the rollator's wheels, a suspension hook (6) to hang the rollator's frame, and a locking pawl (8) to secure the rollator against unwanted movement during use of the device. The design is such that one wheel of the rollator can be placed in the wheel catcher while the rollator's frame is suspended from the hanging hook, after which the locking pawl is positioned at such a height that the rollator cannot detach from the wheel catcher and the hanging hook during use of the vehicle. Preferably, the hanging hook and the locking pawl are rotatable.

Description

Short designation: Device for attaching a roller- later to a vehicle such as a mobility scooter DESCRIPTION 10 The invention relates to a device for the attaching a walking aid, hereinafter referred to as a rollator, to- attaching a running frame and running wheels to a vehicle for elderly and disabled people, in particular a mobility scooter. 15 The present invention aims to provide a univer- suitable equipment for use with a mobility scooter or be able to take such a vehicle with you from a (folded) rollator. 20 To that end, the invention provides for an in- direction for attaching a preferably foldable walking aid, hereinafter referred to as rollator, comprising a walking- frame and running wheels, on a vehicle for the elderly and min- disabled persons, in particular a mobility scooter, hereinafter referred to as- 25 called harness, where the arrangement includes: - a support frame designed to be transported with the vehicle to become unions; - preferably at a height relative to the support frame 30 adjustable wheel catch, intended and designed to during use of the device one of the running wheels of the roller- to be caught in lator; - preferably relative to the support frame in height adjustable suspension hook, intended and designed to during use of the device the walking frame of the rollator to hang up; 5 - preferably at a height relative to the support frame adjustable locking pawl or hook, hereinafter locking pawl named, intended and designed to during use of the in- towards the walking frame of the rollator against unwanted to lock its upward movement, 10 everything executed and arranged in such a way that of the rollator one running wheel can be placed in the wheel catcher while a part of the walking frame of the rollator at the top hanging hook is hung up, after which the locking pawl is positioned in such a way- any height is applied and adjusted so that the rollator 15 cannot detach from the during use of the vehicle wheel catcher and the suspension hook. Preferably, the suspension hook is rotatable around a rotation axis. perpendicular to the main direction of the support frame. The locking 20 delpal is preferably rotatable around a rotation axis in the main direction of the support frame. The invention will now be discussed in more detail on the basis of of the figure description below. Figure 1 shows an implementation example of an in- direction according to the invention; Figure 2 shows the same execution example of the invention, incl. a rollator. Figure 1 shows an implementation example of a facility 1 according to the invention, for attaching a bee preferred folding walking aid, hereinafter referred to as a rollator (not shown), comprising a running frame and running wheels, to a vehicle for the elderly and disabled, in particular a mobility scooter, hereinafter referred to as the vehicle (not shown). The arrangement shown in Figure 1 comprises a support frame 2 that is configured to be connected to the vehicle, for example by means of a clamp (not shown), and then primarily located on the outside of the vehicle 10 extends vertically. Furthermore, facility 1 comprises a relative to the height-adjustable carrying frame (see arrows 3), for example image more or less 0-wormy wheel catcher 4, intended and incorporated 15 directs during use of the facility 1 one of the to be able to clamp the walking wheels of the rollator more or less on catch. Facility 1 further comprises a relative to the 20 support frame 2 height-adjustable (see arrows 5) suspension hook 6, intended and designed to during use of the in- to be able to lean towards the walking frame of the rollator hang. 25 Finally, the arrangement 1 comprises a relative to the height-adjustable support frame (see arrows 7) locking pawl or hook, hereinafter referred to as locking pawl 8, intended and designed to, during use of the facility, the walking frame of the rollator against unwanted movement To lock 30 upwards. Everything has been executed and arranged in such a way that the role one running wheel can be placed in the wheel catcher 4 while (a part of) the walking frame of the rollator to the suspension hook 6, twisted and secured in the as shown in the figure the displayed position is hung up. Then the ver- locking pawl 8 installed at such a height and in the in fi- 5 figure the set position set so that the tollator from above is clamped and thereby during use of the feed- harness cannot detach from the wheel catcher 4 and the suspension hook 6. 10 As figures aa and lb show, the suspension hook 6 is rotatable (see arrows 9) is around a rotation axis 6a perpendicular to the vertical main direction 2a of the support frame 2. The locking pawl 8 is in two positions by means of a square tube executed support frame 2- rotatable (see arrows 10) to a 15 rotation axis corresponding to the principal direction 2a of the support frame 2. Figure 2 shows the same implementation example of the out- invention as in Figure 1, which illustrates how a 20 rollator is installed in it. Thus, the present invention provides for a universally applicable device for using a mobility scooter can carry a trailer or similar attached vehicle 25 a rollator or similar walking aid. With regard to that referred to as Dl in the Novelty Report- Regarding patent specification US5129559A, the following is noted. The layout known from D1 and the layout according to the 30 inventions distinguish themselves in that in D1 -in contrast- ling to what the Preliminary Investigator believes to see - it in D1 shown part 30 is not a locking pawl or hook, but serves only to catch the (large) rear wheel of a wheelchair if it is connected to the vehicle 11 a support frame is used for this purpose (see Figure 3 in D1). In other words, part 30 has that function. wheel catcher. If the (same) support frame is used for 5 carrying a bicycle (see figure 4 in D1), then becomes one of the bicycle wheels caught in a wheel catcher 42 and part 30 is not in use. Therefore, the content reads of Dl not on claim 1 of the present patent application question and is the content of conclusion 1 new and inventive 10 in relation to the content of Dl, especially since in Dl as "locking" of the object to be carried (bicycle or wheelchair) chair) against the possibility of falling off the support frame, ge- use is made of resilient bands 14, while in the device according to the invention is provided therein with 15 the, preferably adjustable, locking pawl 8, whereby a considerably better (after all, form-cast, see https: / / nl.wikipedia.org / wiki / Verbindingstechnologies) protection against loosening / falling off of the carrying object is achieved. ... .... ...... .... .... • ... ..... . ...... .......... ... .... ....... oo ........... ...

The entire main conclusion reads on the layout known from D1, since the suspension device is not limited to a rollator and the height adjustment of the various parts Written Opinion Patent application 1044157 concerns a preferred variant, but the measures of the main conclusion are not limited to that. The main conclusion is therefore not new. measures of follow-up conclusions 2 and 3, regarding the rotatability of the suspension hook and locking pawl have not been found in patent literature and are therefore new and inventive. D2 is a known suspension device for a rollator (see figure 4) of which the suspension hook (72) is not is honorable. D3 is a known suspension device for a rollator (see figure 4) of which the locking pawl (114) is honorable.
