Problems solved by technology
[0004] However, such castors are often aesthetically unappealing, and other configurations have been considered where the armchair typically rests on supporting feet and the chassis can only be extended if the armchair is to be moved
However, this solution also requires additional investment in the upholstery of the backrest area in order to obtain a pleasing aesthetic impression
In addition, the operation of the pedals requires a certain amount of force, and in some cases, the elderly cannot use this certain amount of force.
Last but not least, a chassis that can be extended with footrests adds to the cost

Embodiment Construction
[0025] figure 1 The armchair according to the invention is shown in its reclined position. It has a seat 1 , a backrest 2 and a footrest 3 . The armchair is also provided with two side walls 4 which delimit the seat 1 laterally and which can also serve as armrests. Furthermore, the armchair has a front support foot 5 and a rear support foot 6 , on which the armchair rests on a support surface 7 in the tilted position shown. Seat 1 also has seat frame mechanism 8, and this seat frame mechanism 8 is connected with footrest adjustment mechanism 9 and backrest adjustment mechanism 10, and footrest adjustment mechanism 9 is used for extending and retracting footrest 3, and backrest adjustment mechanism 10 is used for in the upright original position and as figure 1 Seat 1 and backrest 2 are adjusted between the reclined relaxed positions shown. In order to better describe the structure of the armchair, the decoration of the seat and footrest has been omitted from the figure.

According to the invention, the armchair has a seat, supporting feet, a stand-up aid, and a chassis with wheels for moving the armchair. The chassis is adjustable relative to the supporting feet between at least a first and a second position, with the wheels being spaced apart in the first position of the footprint while the armchair is supported with the supporting feet on the footprint, and withthe wheels being in rolling contact with the footprint in the second position while the supporting feet are arranged so as to be spaced apart from the footprint. The aid has an adjustment mechanism with a servomotor, with the adjustment mechanism being coupled with the chassis for the purpose of displacing the chassis by means of the servomotor between the first and second position.
Description
technical field [0001] The invention relates to an armchair with a standing aid. Background technique [0002] The advantage of an armchair with a standing aid is that the armchair can be easily tilted forward using a remote control or control knob, allowing the user to lift themselves off the cushion very comfortably. This function is especially easy on the back because no sudden effort is required to stand up. However, the mechanism also sits in a particularly gentle and comfortable manner. [0003] Such armchairs are often implemented as so-called chaise longues, which also offer the opportunity to tilt the backrest and extend the footrest. One or more servo motors are used to move the armchair into various positions, with the result that such armchairs can be quite heavy. Therefore, the armchair inevitably needs casters in order to move easily to another location. However, once the correct position of the armchair has been found, it is desirable to be able to secure ...
