Description:
WAGON

The invention relates to an aid for persons with a reduced ability to move around by themselves. More specifically does it relate to a rolling aid formed as a four-wheeler with seat, wheels and steering.

Many people with reduced movability are having trouble moving around at home. There are different solutions to help them moving around, among others variations on so-called pulpits or walkers and wheel chairs.

It is for example known to use specific aids in the form of four wheeled aids for persons having one foot that should not be used, and where they for some reasons cannot use crutches or the like. The person is then resting the harmed leg on a seat with an adapted shape on the four wheeler and push off with the functional leg, while the person is steering the four-wheeler by means of a handle bar or steer.

These four wheelers are assuming that the person can stand on one functional leg and in addition has a good balance. For persons having such a poor health that they cannot stand upright over a shorter or longer period of time, such a four-wheeler cannot be used, as there is a danger that the user fall of the wagon and harms herself even worse.

There are also known different wagons where the person is supported in support bows or the like while she or he is sitting on the wagon, so that she does not fall of the wagon due to reduced ability to maintain upright or to keep the balance.

However, the user of such wagons will be dependent on help from another person to get into and out of the wagon and sometimes also to advance.

JP 2007 215636 describes a walking aid vehicle comprising a frame and a seat attached to the frame. The upper part of the frame is designed and adapted to be used as a handle. There are arranged wheels on the lower part of the frame. This type of walking aid vehicle might be rather difficult to manoeuvre around in a furnished home with limited space.

There are situations where a person is sufficiently healthy to manage on her own over shorter or longer periods, but may nevertheless experience large difficulties in moving from one place to another, for example from the bed to the toilet, from the living room to the kitchen, etc., which are natural incidents that will happen several times during a normal day.

It is an object with the present invention to provide a wagon that makes the user able to on their own in an easy way to get from one resting place over onto the wagon, to move around by their own by their own means and also reach a new resting place. With resting place it is here meant a place where the user is staying over a shorter or longer period of time, either to perform a task or to rest.

This is obtains by a wagon according to the attached independent claim 1. Advantageous embodiments are stated in the dependent claims.

According to one aspect, the invention relates to a wagon comprising seat, handle, wheel holding arms and wheels, where an anchoring bracket holds the seat, the wheel holding arms are attached to a first end of the arms, a second end of the arms is provided with wheels, at least one elongated handle comprising a first end and a second end, the handle is fixedly mounted to the seat with a fi rst end in such a way that a gripping part on the second end of the handle is extending over one side of the seat and along mainly the complete length of the seat. Thereby, the gripping part of the handle is extending along one side of the seat and at a certain distance from the seat both vertically and horizontally in such a way that the user gets the handle along his or her side under or next to the arm and above one of the legs.

Such a wagon provides a light construction as the functional elements are composed of elongates elements such as tubular profiles holding wheels and handles and that are kept together by plain fastening brackets or equivalent fastening means. Such a light construction provides good navigability, while the extension of the handle along the complete length of the seat at the same time provides a long gripping surface and a good support for the user of the wagon.

In another aspect, the wagon comprises two handles, where the gripping part of the handles extend over each side of the seat and along mainly the whole length of the seat in such a way that there is formed a passage between the handles over the seat. The handles will then extend along the seat in a distance over each side of the seat vertically and horizontally. The specific shape and extent of the handles, i.e. that the handles are extending from the front side of the seat, upwards and backwards either on one side or both sides of the user, gives a specifically good support for the user of the wagon.

The passage between the handles of the wagon are open towards the back edge of the wagon. Thereby, a user with reduced mobility will automatically push herself into correct position on the wagon and does not need to use power to comfort herself further when she has moved herself onto the seat from another support.

The seat part of the wagon advantageously comprises a seat bracket, where an attachment part of the handle is attached or removably attached to the seat bracket or a long side of the seat bracket. The fastening of the handle to the seat bracket one the seat part of the wagon makes the handle unable to rotate. This is especially advantageous, as an essential advantage of the described wagon is that it provides support sideways during use. If the handles are removably attached to the seat bracket, this will make it possible to exchange handles or adjust the length of the handles, so that one wagon can be adapted to different users, for example with different height or weight, or possibly different degree of movability.

According to one aspect of the invention at least one of the wheels are provided with an auxiliary motor. The use of one or more auxiliary motors is particularly advantageous if the user of the wagon has a very reduced movability and will have problems moving the wagon onwards by means of the legs.

A wagon according to the invention comprises preferably at least one or two wheels that are rotatably attached to one or two of the wheel holding arms. The rotatabie wheels make it possible for the user to rotate the wagon even if the handles are fixedly attached to the seat part.

The seat or a seat arrangement can be attached or rotatably attached with a height adjustable arrangement, such as a height adjustable cylinder, to the attachment bracket. This makes it possible to adapt the wagon to users with shorter or longer legs and for the user to adapt the wagon to the height of a surface she wants to move over to.

According to one aspect of the invention, the cylinder and/or at least one of the auxiliary motors are controlled by a remote control via a control unit at by buttons on the handles. Such auxiliary motors can also be used to wheel the wagon away from the user when it is not to be used or the wheel it back again when it is put to use again, instead of the user stretching out to grab the wagon and draw it towards herself.

According to another aspect of the wagon, the wagon comprises an attachment device for the seat, where the arms and wheels are rotatably attached to the seat or seat is rotatably mounted on the attachment device. Such a rotatabie solution can give advantages for example in private homes where the accessibility can be reduced by small room size or furniture. When the user has moved the seat as close as possible to a desired sitting surface, the seat can possibly be rotated to improve the line of movement from the wagon over onto the sitting surface.

It is especially advantageous about the present invention that the wagon is open backwards, so that a user can push herself onto the seat. It is also

advantageous that the steer, handlebar or bars one the wagons are fixed to the seat, so that the handlebar does not rotate if a user put a load on the handle or handles for example sideways.

The invention will now be further described with reference to the attached drawings where: Figures la and lb shows perspective views of a first and a second embodiment of a wagon according to the invention.

Figures 8a and 8b show an alternative embodiment of the handles on the wagon.

Figures 9a and 9b show an alternative embodiment of a wagon according to the invention.

Figure la shows a perspective view of a first embodiment of a wagon 1 according to the invention. The wagon 1 comprises a seat 2, handle 3, wheel holding arms 4 with associated wheel 5. The seat 2 and the wheel holding arms 4 are mounted on an attachment device in the form of an attachment bracket 6. The seat 2 in the shown embodiment is attached to a cylinder 7 that advantageously can be a hydraulic cylinder. The cylinder again is attached to the attachment bracket 6, so that the seat is kept at a distance over the attachment bracket. It is also possible to attach the seat in the attachment bracket in generally known manner by means of a pole, where the seat possibly can be set in different heights over the attachment bracket.

The other end of the wheel holding arms 4 are attached to the attachment brackets 6 so that the arms 4 are extending in different directions. In the other end of the arms 4 there are attached wheels. As the arms 4 have a certain length and are pointing outwards in different directions, there is created a space distance the wheels, which increases the stability of the wagon.

In the shown embodiment, there are mounted auxiliary motors 8 on two of the wheels. The auxiliary motors 8 are propelling the wagon forwards or backwards if the user does not have sufficiently good mobility of move around on her/his own. The auxiliary motors can also be used to move the wagon away from the user when it is not in use and drive it up to the user when it is again needed. The auxiliary motors can for example be controlled by a remote control or buttons on the handles. The motors can advantageously be arranged so that they can be operated separately to turn the wagon. Thereby, the buttons controlling the motors can control each motor separately, so that one motor is passive while the other is running, that the motors are driven at different speeds, or that the motors are driven in opposite directions. Furthermore can the wagon be equipped with locking of the wheels, so that the wagon does not roll away when the user is leaving it.

Figure lb shows a perspective view of a second embodiment of a wagon 1 according to the invention. The wagon is equipped with arms 4 holding wheels 5, where the arms are attached to an attachment bracket 6, corresponding to the first embodiment above. Over the attachment bracket 6 there is a seat 2 mounted on a cylinder 7. The wagon further have handle 3 extending forwards from the underside of the seat 2 in a bow in front of the seat and up on a bow along the length direction of the seat, so that each handle form a sideways support on each side of the seat, along the length direction of the seat.

Figure 2a shows a rear view of the wagon in fig. la. The wagon is designed so that the wheel arms 4 are extending outwards, forwards and backwards from the wagon, but will not be an obstacle directly at the side of the seat 2. The handles 3 are fixedly attached to the seat 2 in front of the seat. The handles 3 are designed as elongated elements extending upwards and lightly tilted outwards from the front edge of the seat 2 and thereafter backwards along the seat 2, so that there is formed a passage between the handles 3 over the seat. When a user is setting herself on the wagon, she preferably take a grip on the handles and pulls herself over onto the seat while she at the same time pulls the wagon towards herself, so that she finally will be placed in the passage between the handles 3 over the seat 2 and thereby can sit down with one leg on each side of the seat.

Figure 2b shows a rear view of the wagon in fig. lb, while fig. 2c shows a front view of the wagon in fig. lc. The handles 3 are made of bent metal pipes or tubes or rods, for example steel, aluminium or the like or tubes or rods in a composite material, for example a carbon fibre reinforced polymer, as long as the chosen material has sufficient strength to be suitable for support for a person and at the same time have a lowest possible weight. In the shown embodiments, the handles 3 are made of bent tubes with a mainly smooth surface.

The handles 3 comprises an anchoring part 31, a transition part 32 and a gripping part 33, se e.g. figs. 2c or 6a. The anchoring part 31 is attached to the underside of the seat 2. How the anchoring part 31in this embodiment is attached to the seat will be further explained on relation to figure 7. The gripping part 33 of the handle is the part of the length of the handle where it is natural for the user to hold onto the handle during use. As the wagon is envisaged for use by several different users, the gripping part will extend over most of the part of the handle that is lying over or by the seat. The gripping part 33 of the handle is preferably covered with a material that provides a good grip comfort, preferably with a certa in softness and a surface quality giving good contact and friction for a hand. Between the gripping part 33 and the anchoring part 31 a transition part is extending in front of the wagon 1. In the embodiment shown among others in the figures 2b and 2c, the two handles 3 are joined in front of the wagon, so that there is obtained a further stability and strength for the handles. It is also conceivable to let the transition parts extend up on each side of the wagon, such as in the first example of an embodiment of the wagon, e.g. shown in figure 2a.

In the shown embodiments, there are at least to rotatable front wheels on the wagon. In many occasions it is most profitable if all the wheels of the wagon are rotatable. To move around with the wagon, the user holds firmly onto the handles 3, which also serves as a sideways support and walks along sitting on the wagon, corresponding to how babies are moving around in baby walkers made to learn to walk. The user can also activate the auxiliary motors 8 on the back wheels 5", so that she gets help moving the wagon.

The handles are fixedly mounted to the seat and will not control the wheels. This makes the handles able to be used as support when the user is elevating to get onto or off the wagon and as sideways support during use of the wagon. It is especially advantageous with a sideways support if the user has little control with own mobility or has a bad balance, as the handles then will prevent the user from falling off the wagon. This gives an extra safety, for example if the user is alone when she is moving around by means of the wagon or if she suffers from deceases that can give spasms or the like.

Figure 3 shows a side view of the wagon 1. To control the cylinder 7 holding the seat and possibly auxiliary motors on one or more of the wheels, there can be arranged a control unit 9 below the attachment bracket 6. The attachment bracket 6 can for example be a metal plate where there are made anchoring organs for the wheel arms 4, seat cylinder 7, control unit 9 etc. The attachment bracket will be further described below.

Figure 4a shows a top view of the wagon in fig. la, while figure 4b shows a third embodiment of a wagon according to the invention, in a top view. The wagon 1 can be made either with single wheels at the end of each wheel arm 4, as shown in figure 4a. However, it is also possible to make the wagon with double wheels at the end of each wheel arm 4, as shown in figure 4b. The choice of single or double wheels can for example depend on the requests of the user, which surfaces the wagon is used on and the weight of the user. The size of the wheels can of course be changed, so that a wagon that for example is to be used in a house with relatively high doorsteps are provided with wheels with a larger diameter than the shown embodiments to make it more easy to pass over the doorsteps.

On figures 4a and 4b it can also be seen how the handles on the grippi ng part 33 are extending along the seat from the front of the wagon to the rear, so that there is formed a passage over the seat. Further it is shown that the wheel arms are extending outwards from the seat in front of and behind the area where the user will sit during use of the wagon. The wheel arms will therefore not be an obstacle for the legs of the user or force the users to spread their legs more than necessary to sit over the seat.

The seat is made relatively narrow, as it is not envisaged for use over longer time periods, but only work as support in shorter transition phases from one resting place to another. It might therefore give a relatively large load on the bottom of the user if the user for example is very overweight, but will in return provide a high accessibility to the wagon. The distance between the handles can be adapted to the size of the user, so that they give sufficient space to get onto and off the wagon, while at the same time being sufficiently close to each other to provide a good sideways support for the user.

Figure 5 shows a perspective view of a wagon 1 according to the invention.

If it is desirable, can the seat be mounted in a rotatable cylinder, so that the user is not dependent on rotating the lower part of the wagon if she wants to turn towards a resting place. The lower part is her used of the elements comprising attachment bracket 6 with attaching elements, cylinder anchor and the like, wheel holding arms and wheels.

Figures 6a and 6b shows a side view of the wagon 1 in a first and second position. For the wagon to be usable for users of different sizes, it is an advantage if the seat can be lifted and lowered, as shown in figures 6a and 6b.

The handles 3 are shaped as elongated bows with a gripping part 33 and an attachment part 31. The attachment part is connected to the gripping part by means of a bow-shaped transition part 32. The bow-shaped transition part 32 is bent so that the attachment part 31 and the gripping part 33 to a certain extent is lying over each other. Thereby the attachment part 31 will lie along the seat 2 at the edge of a seat bracket 16, while the gripping part 33 of the handle is lying along the seat 2, but in a certain distance from this both vertically and horizontally. It is an advantage if the gripping part 33 of the handle 3 has a bow shape, so that it gives a good ergonomical sensation for the user. Figure 7 shows a section of a wagon according to the invention, showing the attachment bracket 6 and the seat bracket 16. In the shown embodiment the attachment bracket is formed as a rectangular plate with short sides 10 and long sides 11. Along the longest sides of the bracket 6, there are hollow tubular anchoring organs 12. The wheel holding arms are fixedly attached to these tubular anchoring organs 12. Alternatively can the wheel holding arms be directly attached to the short sides 10 or the long sides 1 of the attachment bracket 6. Further is there arranged a cylinder fastener 13 in the attachment bracket. The cylinder fastener 13 is shown as a rib reinforced tubular pass through that is arranged across the attachment bracket 6. The cylinder fastener 13 can also be used as a tubular fastener, where a seat holding pipe is attached in a rib reinforced tubular pass through.

The seat bracket 16 is in the same way as the attachment bracket a rectangular plate with short sides 10 and long sides 11. Along the long sides 11 of the seat bracket, there is attached tube anchoring organs 12' for mounting of the attachment part 31 of the handles 3. The seat bracket 16 is provided with seat anchoring organs 17 for mounting of a bolstered seat on the seat bracket.

To increase flexibility for the wagon and the possibilities to adapt the wagon to different users, the tube anchoring organ 12' can for example be provided with holes (not shown) for spring biased knots (not shown) in the handles attachment part 31, so that one can in known ways attach the attachment part 31 to the tube anchoring organ 12' and liberate the attachment part by pressing the knots in through the holes. When the knots are liberated from the holes, the attachment parts can for example slide in length direction or be angled outwards and inwards to increase or narrow the passage between the handles.

For the manufacturing of the wagon the design of the brackets as described above will enable a quick assembly of the different parts of the wagon, so that the production costs are maintained as low as possible.

Figures 8a and 8b show an alternative design of handles of the wagon. To increase manageability of the wagon, especially if it is not provided with auxiliary motors, the wagons can be provided with an extra handle extending further out and/or longer backwards from the wagon. If the wagon is too far away for the user to be able to get a hold of the handles, the helping handle will provide a larger range so that the user can hold onto this and pull the wagon towards herself.

Figures 9a and 9b show an alternative embodiment of a wagon according to the invention. In this embodiment the wagon is formed with a seat 22, handle 23, wheel holding arms 24 and wheels 25. An attachment device 26 for the seat is in a first end attached to the wheel holding arms and the handles 23. A seat 22 is mounted on the attachment device in a second end of the attachment device, so that the seat is situated at a distance below the handles and above the wheels on the wheel holding arms 24. The seat can also in this embodiment be mounted on a cylinder to adjust the height of the seat or by means of a seat rod, that possibly can be attached at different heights above the second end of the attachment device 26.

It is thereby described a wagon comprising seat 2, 22, handle 3, 23, wheel holding arms 4, 24 and wheels 5, 25. The wagon comprises an attachment device 6, 26 for holding the seat 2, 22, wheel holding arms 4, 24 being connected with the seat 2, 22 or attachment devices 6, 26 in a first end of the arms 4, 24, a second end of the arms is provided with wheel or wheels 5, 25. The wagon further comprises at least one elongated handle 3, 23 comprising a first end section and a second end section, where the handle is fixedly or releasably attached to the attachment device 6, 26 for the seat or to the seat 2 at the first end section in such a way that a gripping part 33 at the other end section of the handle 3, 23 is extending over one side of the seat and at a distance from the seat both vertically and horizontally.

It is a shared feature of all the shown embodiments that the handles are firmly attached in relation to the seat or fastening device for the seat during use. It is further a shared feature of the embodiments that the handles are attached so that they will be at a distance over and to the side of the seat. Even if this is not shown, it is possible to perform the invention with only one handle in all the shown embodiments. The handle will then extend along one side of the seat and at a distance from this side. The one handle will be firmly or fixedly attached in relation to the seat or attachment device for the seat.

It is an advantage of the present invention that the wagon is open backwards so that the seat is accessible from the rear, so that a user can pull herself in and onto the seat by means of the handle or handles. It is therefore sufficient for a user to stand up and the pull the wagon in under herself and sit down.

The embodiments with four rotatable wheels make the wagons easy to manoeuvre. It is an advantage for users with a very reduced mobility that are getting up onto and off the wagon that the wagon is easily placed where the user wants it to be. At the same time can the rotatable wheels simplify manoeuvring in furnished rooms where there is limited free space to move the wagon.
