Description

The present invention relates to a sitting and standing furniture for supporting the movement of a person with muscular hypotonia, ataxia and/or spastic cerebral palsy (CP), with a seat surface, a back device extending upwards, a first side device, a second side device, a standing device extending downwards towards the floor and with a connecting device, wherein the connecting device connects the first side device and the second side device and the back device, the first and second side devices and the connecting device delimit a first range of movement above the seat surface.

Such a device is known from the general state of the art of seating furniture. Seating furniture is generally suitable for making it easier for people to sit. Standing furniture, in turn, is generally suitable for making it easier for people to stand. However, for people who suffer from muscular hypotonia, ataxia and/or spastic However, for people suffering from cerebral palsy, such seating or standing furniture does not help to support movement from a sitting position to a standing position or vice versa. This problem occurs both in older people with age-related muscle weakness and in children with muscular hypotonia, ataxia and/or spastic cerebral palsy.

The present invention is intended in particular for children with the aforementioned impairments, but can be used by all people with these impairments. People with muscular weakness, ataxia and/or spastic cerebral palsy find it difficult to stand up and sit down freely, and there is always a risk of falling during the associated movements. Children with muscular hypotonia, ataxia and/or spastic cerebral palsy are also at risk of losing their balance when sitting and standing. With conventional seating or standing furniture, it is not possible to support a person in standing up and sitting down, so that the movement in one direction or the other is not only easier, but the movement can also be carried out more easily and in a more controlled manner.

The object of the present invention is therefore to further develop a seating and standing furniture of the type mentioned at the beginning in such a way that it supports the movement of a person between a sitting position and a standing position.

The object is achieved according to the invention in that the seat surface, the first side device, the second side device and the connecting device delimit a second movement area in front of the seat surface and the connecting device is designed as a knee support in the second movement area.

With the present invention, it is possible for a person with muscular hypotonia, ataxia and/or spastic cerebral palsy, for example a child, to sit on the seat of the seating furniture and the first and second side devices prevent the child from falling sideways from the seat if it loses its balance. The connecting device also secures the child at the front. In addition, the connecting device limits a second range of motion in such a way that the child can stand up with its knees on the connecting device so that it serves as a knee support and prevents the child from falling forward. The connecting device provides a support for the child's knee in the second movement area so that the child can move upwards into a standing position or downwards into a sitting position with the support of the connecting device.

A further advantage of the present invention is that the first side device comprises a first standing element of the standing device and the second side device comprises a second standing element of the standing device. As a result, the standing elements are designed as part of the side device and can be connected to the seat and the back device in a chair-like manner.

A further advantage of the present invention is that the connecting device has a first connecting element for limiting the first range of motion and a second connecting element for limiting the second range of motion. This construction allows the seating and standing furniture to be designed to be more "open". For example, between the first A free, transparent area remains between the connecting element and the second connecting element through which the child's sitting position on the seat can be observed from the outside.

It is also an advantage of the present invention that the second connecting element is a surface element which extends with a main surface substantially parallel to the backrest. This ensures that the area in which the second connecting element provides a support area as a knee support is larger. This is particularly advantageous if the seat surface is height-adjustable.

A further advantage of the present invention is that the main surface has a middle third in the parallel direction of extension, with which the main surface limits the second movement area between the seat surface and the main surface. This ensures that the second surface element can serve as a knee support not only when the seat height is different, but also when children of different heights sit on the seat surface at the same height. The surface design of the second Connecting element or the connecting device as a whole provides a larger range of use under different conditions of use, i.e. under different seat heights and/or different body sizes.

It is also advantageous that the connecting device comprises a play surface which extends substantially parallel to the seat surface. Such a play surface enables the child to find motivation to move his arms in a sitting position or in a standing position.

Another advantage of the present invention is that the playing surface is attached to the first side device and the second side device in a height-adjustable manner. The height-adjustability of the playing surface makes it possible to adapt it to the child's height.

A further advantage of the present invention is that the first connecting element comprises a playing surface which extends substantially parallel to the seat surface. It is advantageous that the Play surface is located on the upper, first connecting element and on the other hand forms an upper tray as a play surface, which at the same time represents a barrier for the child, preventing the child from falling forwards out of the seating and standing furniture if he or she loses his or her balance.

Another advantage of the present invention is that the stand includes a base plate. The base plate increases the stability of the stand and thus of the seating and standing furniture.

It is also an advantage that the base plate extends outwards from the first side device, the second side device and the back device. This expansion of the standing areas formed by the side devices further increases stability.

It is also an advantage of the present invention that the back device has a rear side to which a boom support is attached. Such a boom support advantageously extends over the first movement area and is preferably U-shaped there. designed as a round rail. Objects that the child needs can be hung on such a round rail. The round rail also serves to provide the child with another option to hold on to when standing.

Further advantages arise from the additional features of the subclaims. Overall, the seating and standing furniture also serves to provide the child with a safe space for movement, in which it is motivated to move relatively safely and thus improve its mobility.

Fig. 2

a schematic representation of the seating furniture from Fig. 1 in a side view without gallows support and in a kind of sectional view

In Fig. 1 a seating and standing furniture 1 is shown schematically and in perspective. The seating and standing furniture 1 is intended to support the movement of a person with muscular hypotonia, ataxia and/or spastic cerebral palsy from a sitting position to a standing position or from a standing position to a sitting position and to provide the person with a safe close environment when sitting and standing. For this purpose, the seating and standing furniture 1 comprises a seat 3, a first side device 5.1, a second side device 5.2, a back device 7, a standing device 9 and a connecting device 11.

The seat surface 3 is mounted so that its height can be adjusted between the first side device 5.1 and the second side device 5.2. In the present embodiment, the seat surface 3 is aligned horizontally. In other embodiments, however, the seat surface 3 can also be adjusted in its alignment via an adjusting device (not shown) so that it is inclined in the direction of the connecting device 11 in a sitting position.

The height adjustment can be provided technically in any way. In the simplest form, the first side device 5.1 and the second side device 5.2 comprise support elements (not shown) at different heights. In other embodiments, however, more complex technical devices can also be provided, for example the aforementioned adjustment device in order to adjust the seat height step by step or continuously.

In the Fig. 1 In the embodiment shown, the first side device 5.1 and also the second side device 5.2 each comprise a first surface element 5.3 and a second surface element 5.4, respectively, which extends far upwards on the sides of the seat surface 3 along the back device 7, so that armrests (not shown), for example, can be formed on an upper edge 5.5 of the respective first and/or second side element 5.1, 5.2. The back device 7 extends upwards over the upper edge 5.5. In the present embodiment, the back device 7 extends to the head height of a seated person, so that the back of the seated person's head can be supported on a head region 7.1 of the back device 7.

In the present embodiment, the connecting device 11 is designed in two parts. In other embodiments, the connecting device 11 can also be designed in one part and in the one-part design can comprise a playing surface 13 which, as the upper end of the one-part connecting device 11, forms a barrier between the first side device 5.1 and the second side device 5.2 in order to protect the person or the child from falling forward.

The first side device 5.1, the second side device 5.2, the back device 7 and the connecting device 11 delimit a first movement area 15 in both the one-part and the two-part embodiment shown. The playing surface 13 comprises a first outer longitudinal edge 13.1 and a second inner longitudinal edge 13.2 in the embodiment shown. The first and second longitudinal edges 13.1, 13.2 are optional. In other embodiments, only an outer or an inner longitudinal edge can be provided or the longitudinal edges can be omitted entirely. They serve to limit the movement area present on the playing surface. To prevent objects from falling off the playing surface 13.

In the Fig. 1 In the embodiment shown, the connecting device 11 is designed in two parts and comprises a first connecting element 11.1 and a second connecting element 11.2. The first connecting element 11.1 comprises the playing surface 13 with the first and/or second longitudinal edge 13.1, 13.2, while the second connecting element 11.2 is designed as a surface element that extends essentially parallel to the back device 7 and is arranged at a vertical distance from the first surface element 11.1 between the first side device 5.1 and the second side device 5.2. In the present embodiment, the second connecting element 11.2 is fixedly attached. In other embodiments, the second connecting element 11.2 can also be attached detachably, for example pivotably, to the first and second side parts 5.1 and 5.2 for cleaning purposes or for other reasons.

The stand device 9 comprises a lower area 9.1 of the first side device 5.1 and the second side device 5.2 below the second Connecting element 11.2 and a base plate 9.2. The base plate 9.2 extends outwards from the first side device 5.1 and the second side device 5.2 and enlarges a standing area of the seating and/or standing furniture 1. In the Fig. 1 In the embodiment shown, the base plate 9.2 has a U-shaped cutout 9.3 into which the first side device 5.1 and the second side device 5.2 are precisely inserted. As a result, there is no base plate 9.2 below the seat surface 3.

A boom support 17 is attached to a rear wall 7.2 of the back device 7 and can either have a fixed height or be height-adjustable. The boom support 17 is designed as a round rail extending in a U-shape over the first movement area 15.

Between the connecting device 11 in the one-part embodiment or the second connecting element 11.2 of the two-part embodiment shown and the seat surface 3, a second movement area 19 is created, which is laterally limited by the first side device 5.1 and the second side device 5.2. and in Fig. 2 can be clearly seen. The connecting device 11 in the one-piece embodiment or the second connecting element 11.2 in the one-piece embodiment shown has a knee support 11.3 (see Fig. 2 ). The design of the knee support 11.3 can vary. In the simplest form, as in Fig. 2 As shown, the smooth inner side of the second connecting element 11.2 forms the knee support 11.3. In other embodiments, the inner wall of the one-piece connecting device 11 or the second connecting element 11.2 can be ergonomically adapted to the knee of a person, so that the function as a knee support is optimized.

In Fig. 2 is a schematic side view of a sectional view of a seating and standing furniture 1 according to the invention. In Fig. 2 The gallows support 15 and the inner longitudinal edge 13.2 are missing. The allocation of the individual components can be clearly seen from the side view. The seat surface 3 and a middle third of a main surface of the second connecting element 11.2 limit the second movement area 19. In the one-piece embodiment of the Connecting device 11 is the area of the middle third of the main surface of the area of the inner wall of the connecting device 11, which extends parallel to an adjustment range of the seat height of the seat surface 3, such that the person can support himself with his knees on this area provided as a knee support when standing up or sitting down and can thus safely carry out the upward or downward movement.

The first movement area 15 is essentially formed above the seat surface 3 and extends at least over its entire surface. The second movement area 19 is formed below the playing surface 13 and extends at least over its entire surface. As a result, a standing person is trapped between the playing surface 13 on the one hand and the seat surface 3 on the other. During a downward movement, the knees then bend forward and hit the knee support 11.3 until the person is sitting safely on the seat surface 3. Conversely, the person can support their knees on the knee support 11.3 during the upward movement until the person is safely "trapped" between the playing surface 13 and the seat surface 3.

In practice, the sitting and standing furniture 1 can be well padded and also adapted to individual needs. The round rail is also used to hang objects. In particular, the round rail is also used to reduce the body weight of a child with the help of suspensions and to prevent the child from falling over when walking sideways.

In one variant, the seating and standing furniture 1 is designed as a bench for learning to walk sideways.
