Description

A) Prior art:

Children with unstable sitting behavior and low seating capacity, eg. As a result of illness (cerebral palsy, motor / mental disorders) require more support when sitting for eating or playing in the trunk area, so a classic chair is not sufficient. The commercial special seats are very complex screwed, consuming adjustable and therefore very expensive. Likewise, no or very little impulses are exerted on the muscles and nerves by the attached upholstery or foam compounds. In addition, most of the special chairs can not be put on a kindergarten table because of bulky frames and the still high minimum height, so that the children are at eye level.
Likewise, there are already chairs, which are converted by various constructions in high chairs. The undercarriage for this chair stands out because it is specially adapted to this rehabilitation chair and can be connected very quickly and stably by a plug-in system with a single screw connection.

B) invention:

A Rehastuhl for handicapped children, which is predominantly made of wood and without upholstery. The side pads are mounted on a straight back and stabilize the child's torso. The abduction wedge prevents the hip from slipping and supports
sitting upright together with the straight backrest. The arms and upper body of the child are free to move. Thus, it is possible for a disabled child to sit on a normal wooden chair, which has basic devices of a special chair, at the children's table with children of the same age. Due to its low weight and a milled handle on the back plate, the chair is mobile and can be easily taken to all therapy sessions or visits.

An adapted underframe makes it possible to extend the chair to a high chair, so that the child can sit with the same chair at the height of a conventional dining or kitchen table. On the underframe wheels are mounted on the back, which makes it easier to transport the chair in a mated version or pull on the rollers and makes it difficult for the chair to fall backwards.

C) Description and Advantage of the Invention:

The advantage and distinction to conventional special chairs is that the majority of the chair, including the adjustable parts, is mainly made of wood. All parts are straight and without inclination. There were deliberately no upholstery or foam compounds used. Thus, the appearance is natural and aesthetic and comes close in use to a chair for healthy children. The abduction wedge is infinitely adjustable by an iron angle with locking screw. This Rehastuhl is suitable for toddlers from 15 months and supports by the straight back plate, the adjustable pads and the abduction wedge To frame and hold the child in a correct and upright seating position. The child can sit on a child-friendly seat stable and with other children at the children's table. For a second care in the toddler group, in kindergarten to eat, play and paint this chair is ideal. Due to its low weight mobile use is possible. It can be used for therapy sessions, at the waiting room, at the hairdresser's and home, or even as a friend and relative.

Deviating from the patent WO 2012/020325 A1 This rehabilitation chair was equipped with a straight backrest without tilting construction. Likewise, the adaptable parts such as headrest, pads, cymbal holder and abduction wedge are patent WO 2012/020325 A1 padded and the plug-in system of these parts also deviates.

The invention DE 202014007439.9 was optimized in such a way that horizontally milled slots were worked into the back plate, which allows for reversible adjustment of the pads, double-sided and different height adjustment of the pads in height and width. Likewise, a handle was milled in order to move and transport the chair better. To optimize the belt slits on the underside of the back plate have been incorporated and appropriate buckles were attached. Thus, a belt system - if this is necessary for a secure fit - be attached. Also here was deviant too DE202014007439.9 developed a plug and screw connection, which varies the height of the footboard. They are fixed by a screw head on the back and can be individually adjusted by loosening the screw connection, repositioning and tightening again in height. By combining the footstep with the front legs of the chair, the child can neither rock nor overturn due to its own weight.

In the Abduktionskeil (3) an angular connection of iron is incorporated, which infinitely adjust the Abduktionskeil by screwing in the guide rail below the seat and can even remove completely. The abduction wedge between the thighs prevents the pelvis from slipping off and sliding forward; this is infinitely adjustable to the rear and to the front by a swivel fitting attached to the underside of the seat. A Rehastuhl is also off DE2123081 A1 known.

D) Technical description and use 1. Technical description

The children's Rehastuhl consists of the following items (1-8.1): 2 grooved retaining rails for the back plate (1) Cross strut back section below seat plate (1.1) Elements laterally below seat plate (1.2) Element in front below seat plate (1.3) Notch in front for angle guide (1.4) backplate (2) milled slots back plate (2.1) Milled slot (2.2) handle (2.3) 2 plastic buckles on top for belt system (2.4) 2 plastic buckles below for belt system (2.5) Abductor (3) Locking screw with thread (3.1) iron angle (3.2) Pads, 2 pieces (4) Locking screw for pads (4.1) Guide pins per pad (4.2) Screw thread pad (4.3) Shim pad (4.4) seat plate (5) Chair legs front, 2 pieces (6) running board (7) Screw thread footboard (7.1) Locking screw for footboard (7.2) Holes for height adjustment Footboard (7.3) chair tunnel (8th) Cross strut chair cleats (8.1) chair increase (9 - 13.1) frame (9) Frame cross connection (9.1) Frame bow connection in front (9.2) Frame bow connection at the back (9.3) Screw thread in the middle in the frame bow at the back (9.4) screw (9.5) Lying surface for chair cleats (10) Front mounting strip for chair cleats (11) removable mounting bar at the back with screw connection (12) roll (13) Metal bracket for castors (13.1)

The frame of the children's Rehastuhls consists of 2 grooved retaining rails in the back left and right (1) through and on both chair lugs (8), the rear crossbar (1.1), the two lateral elements (1.2) and the front element (1.3) below the seat plate (5). The parts (1.1 - 1.3) are assembled, glued and screwed into a rectangular "U". The seat plate (5) was placed on the parts (1.1 - 1.3) and fixed.

The abduction wedge (3) is rounded off and centered on the seat plate (5) by means of the angular connection (3.1-3.2) screwed. The short leg of the angle (3.2) has been firmly worked into the abduction wedge (3) and the long leg of the angle (3.2) extends below the seat plate (5) in a guide rail and can be tightened by a threaded set screw (3.1). For this purpose, a recess (1.4) was incorporated in the front element (1.3) of the chair frame below the seat plate (5), in which the angle can be moved continuously, horizontally to the seat plate (5).

In the back plate (2), horizontal milled slots (2.1) were worked in, starting from the edge to the left and right. Here, the two pads (4) are connected by a plug-in system (4-4.4) with the back plate (2). In each pad (4) are guide pins (4.2) a milled and centered inside the pad (4) is a screw thread (4.3) incorporated. The two pads (4) are inserted with the machined guide pin (4.2) in the slots (2.1) and fixed in each case by means of a washer (4.4) and a locking screw (4.1) on the back of the back plate (2). The pads (4) can be adjusted individually by loosening the locking screw, moving the guide pins (4.2) into other slots (2.1) and tightening them again, both in height and width.

To hold and carry the chair is located in the back plate (2) top center an oval recess (2.3). In the footboard (7) a square recess (7.2) is incorporated on the left and right, which corresponds to the dimensions of the front chair leg and surrounds them on 3 sides when the footboard (7) is attached. Within this notch (7.2) and into the interior of the footboard (7) in each case a screw thread (7.1) is sunk. To attach the footboard (7), the two screw threads (7.1) are pushed to the left and right at the same time and at the same height in the holes (7.3) of the front chair legs (6). On the back of the front chair legs (6), the footboard (7) is fixed on the left and right with the locking screw (7.2).

It is possible to assemble a standard chest strap for the child's safety. For this adaptable chest strap small slits (2.1) are at the bottom of the back plate (2) left and right attached by which the lower straps pulled through and can be fixed on the back with the overlying buckles (2.5). Also on the back of the back plate (2) below the carrying handle (2.3) again two buckles (2.4) are mounted, which serves to fasten the guided from top to rear straps.

The chair elevation (9-13.1) is brought together with the chair by first loosening the screw (9.5) of the rear cross member (12), removing it and removing the support bar (12) at the rear. Afterwards, insert the chair (1-8.1) slightly tilted forward with the two chair lugs (8) into the rail guide (10) of the undercarriage and push the chair lugs (8) of the chair forward until the lugs (8) with the front suspension of the base (9 + 11) are flush. Then replace the rear retaining strip (12) on the screw connection (9.4) and screw tight with the screw (9.5). Thus, at the same time the chair lugs (8) are enclosed behind, fixed and the chair can not be slipped in the device. Now the children's Rehastuhl was converted by adapting the base into a stable construction of a high chair (1-13.1).

2. Use

This rehabilitation chair is suitable for toddlers over 15 months and supports the child in a correct and upright seating position by the straight back plate, the adjustable pads and the Abduktionskeil. The child can sit on a child-friendly seat stable and with other children at the children's table. For a second care in the toddler group, in kindergarten to eat, play and paint this chair is ideal. Due to its low weight mobile use is possible. It can be used for therapy sessions, at the waiting room, at the hairdresser's and home, or even as a friend and relative.

The customized underframe allows the chair to be made into a high chair so that the child can sit with the same chair at the height of a conventional dining or kitchen table. On the back of the base rollers are attached, which can easily transport the chair in mated version or pull on the rollers.
