Description

The invention relates to a chair, in particular a baby chair, with a support body support, on which a support body assembly is arranged with a seat along a longitudinal axis of the chair for sitting and a backrest surface for leaning a user of the chair, wherein at least one of the seat and / or Backrest surface providing supporting body of the support body assembly is held adjustable by means of an adjustment in at least two mutually different positions on the support body carrier, the chair having a supporting body carrier or at least partially formed by the support body carrier chassis with a roller assembly for rolling the chair on a substrate.

It is known per se that in chairs for adjusting to a favorable ergonomics, for example, the seat, but also the backrest surface, adjusted. This is the case, for example, with typical office chairs. Even with children's chairs, which are modeled on such office chairs, but designed to be correspondingly smaller, such an adaptation is common and advantageous. In particular, it is advantageous if you can adjust the backrest regardless of the seat. However, such chairs are difficult to move on the ground. The handling is correspondingly difficult.

It is therefore the object of the present invention to provide an improved chair.

To solve the problem is provided in a chair of the type mentioned that he has a handle for gripping the chair for rolling on the ground, wherein the handle is firmly connected in its position of use with the chassis and one at an upper end portion of the backrest surface or arranged above the backrest surface handle portion which protrudes in front of a remote from the backrest surface rear side of the support body assembly to the rear, and that between a remote from the backrest surface front end portion of the seat and the handle at least one non-steerable role of the roller assembly is arranged. The chair is suitably steered by means of the handle to a rolling on the ground and / or pivoted using the handle in the manner of a rocker arm on the at least one non-steerable role in a tilted position.

Advantageously, the chair is pivotable on the basis of the here acting in the manner of a rocker handle on the at least one non-steerable role in a tilted position and on the ground on the basis of at least one non-steerable role in this tilted position scrollable. It is expedient if the handle is arranged, as it were, on the free end region of a rocker arm with which the chair can be tilted over the at least one non-steerable roller.

It is also possible that the chair is not tilted, but is low maneuverable on the basis of the handle and the at least one non-steerable role.

An axis of rotation of the non-steerable roller is advantageously perpendicular perpendicular to the longitudinal axis of the chair.

The handle preferably forms a single handle.

The handle is expediently arranged on a profile body, in particular a tubular body.

The handle may be integral with the support body carrier. The handle may be at least partially formed by the support body carrier.

It is preferred if the handle is provided on a handle body which is separate from the support body carrier. The handle body may be located directly on the chassis. It is particularly advantageous if the handle body is firmly connected to the chassis.

It is particularly advantageous if the handle is not articulated, but firmly connected to the chassis. The handle, for example, with the chassis and / or fixedly connected to the chassis component, in particular the support body support, firmly connected, for example screwed and / or glued and / or welded. The handle is in this variant, so to speak always in the position of use.

But it is also possible that the handle is pivotally and / or slidably supported by a bearing assembly on the chassis or other component of the chair. On the basis of the bearing arrangement, the handle can thus be adjusted for example in a non-use of the handle intended non-use position, for example, a stowed position, or in a position of use, is ready for handling the chair based on the handle. The movably mounted with respect to the chassis handle is conveniently based on a fixing device, such as a locking device with at least one latch and / or latching device with at least one resilient detent and / or a clamping device with at least one between a clamping position and a Handle releasing release position adjustable clamp in the use position fixable.

It is also possible that several, for example two, handles are present on the chair. For example, it is possible that such handles are arranged at a transverse distance transversely to the longitudinal axis, so that they can easily grip the operator, each with one hand. If only one handle is present, this is expediently arranged in a plane in which also runs the longitudinal axis of the chair. In particular, it is advantageous if the handle is arranged approximately in a transverse center of the chair.

The at least one handle (several may be provided) has expediently a handle portion which can be grasped and / or grasped by an operator.

The handle portion is advantageously approximately horizontal when using the chair, especially if the chair is not tilted. A longitudinal axis of the handle section expediently runs parallel to the longitudinal axis of the chair.

The measures explained below represent favorable leverage with respect to the handle or handle section:

The handle portion has expediently a distance from a footprint of the roller assembly or the chair on the ground, which is at least about 1 m, preferably 1.20 m, in particular 1.30 m.

The handle portion is expediently at least 1.3 to 1.7 times, preferably 1.4 times or 1.5 times or 1.6 times, as far away from the ground and / or a footprint of the roller assembly on the ground as an upper portion of the Backrest surface or an upper edge of the backrest surface in the furthest from the ground or the footprint adjustable position.

Conveniently, the handle portion protrudes beyond a projection surface of the roller assembly or the chassis on the ground.

A projection surface of the chair, the roller assembly, the seat body or the like is the surface to be considered in a plan view from above on the chair in the direction of the ground.

It is advantageous if the handle portion in front of the at least one non-steerable roller or pair of rollers comprising two non-steerable rollers projecting backwards in front of the chair.

Advantageously, it is provided that the at least one non-steerable roller forms part of a roller pair of non-steerable rollers, wherein the non-steerable rollers are arranged laterally next to the longitudinal axis of the chair and / or on opposite sides of the longitudinal axis of the chair.

The rollers preferably have coaxial axes of rotation or are mounted about a single axis of rotation.

The non-steerable rollers are conveniently mounted on separate pivot bearings.

The non-steerable rollers may be interconnected by an axle shaft or rotatably supported on a common axle shaft.

It is expedient if the chair has at least one support element for supporting the chair on the ground, in particular a roller or a support foot, which is arranged with respect to the longitudinal axis of the chair in front of at least one non-steerable role. It is for example possible that support feet are provided at a longitudinal distance relative to the longitudinal axis of the chair, so that the chair can be tilted or pivoted on the at least one non-steerable role to lift the support legs from the ground and drive the chair on the ground ,

A respective support leg may be fixedly and / or immovably arranged on the chair, for example on a chassis base of the chassis.

A respective support leg is suitably pivotable on the basis of a bearing assembly on a chassis base of the chassis and / or displaceable between a use position in which the support leg for parking the chair protrudes on the ground in front of the chassis base, and a non-use position in which Support foot in an inactive position and / or to the chassis base adjusted position and / or intended for non-use position is adjustable.

It is also possible that one or more steering rollers are arranged with respect to the longitudinal axis in front of the handle and / or the seat surface. So even if the chair is not tilted over the non-steerable role, it can be easily maneuvered on the ground. The non-steerable rollers form, so to speak, a guide aid, while the steerable rollers follow the steering commands of the user of the handle.

The non-steerable rollers have expediently a larger outer diameter than the steerable rollers.

A preferred concept provides that the at least one support element forms part of a support element arrangement comprising at least two support elements, in particular a pair of support elements, a pair of steerable rollers or a pair of support legs, the support elements being laterally adjacent to the longitudinal axis of the chair and / or on opposite sides of the chair Longitudinal axis of the chair are arranged.

Furthermore, it is advantageous if the at least one support element is arranged at a longitudinal distance with respect to the longitudinal axis of the chair in front of the seat, wherein the longitudinal distance is preferably at least 20%, preferably at least 30% of the length of the seat with respect to the longitudinal axis.

It is favorable for the chair when the at least one non-steerable roller is arranged at a longitudinal distance with respect to the longitudinal axis of the chair behind the seat surface and / or the backrest surface. The at least one non-steerable role is therefore in the direction of the handle backwards in front of the seat or backrest surface or both before. The longitudinal distance is preferably at least 5%, preferably at least 15% of the length of the seat surface with respect to the longitudinal axis.

An advantageous concept provides that at least one support element, in particular at least one roller or at least one support foot, for supporting the chair on the ground, in particular all supporting elements, projects laterally in front of the seat and / or is arranged next to a projection surface of the seat on the ground ,

If the at least one non-steerable roller forms part of a roller pair of non-steerable rollers, it is advantageous if a transverse distance of the non-steerable rollers or a track of the non-steerable rollers with respect to the longitudinal axis of the chair is greater than a transverse distance transverse to the longitudinal axis of the aforementioned Support elements, if they are provided as a pair of support elements. For example, a track or a transverse distance steerable rollers or support legs is greater than the track width or the transverse distance of the non-steerable rollers.

The chassis may for example be designed in the manner of a plate or be formed by a plate. For example, support elements and / or wheels are arranged on the edge regions of the plate.

It is possible that the chassis has a chassis body made of one piece, such as cast, molded, forged or the like. The chassis body may also be made of wood. The chassis body may consist of a plurality of components which are fixedly connected to each other, for example a support body which is made of a plurality of components.

It is preferred if the chassis has arms, at the free end regions in each case a roller of the roller assembly and / or a support leg for supporting the chair is arranged on the ground. Such arms can readily be arranged laterally next to a plate. It is also advantageous if these arms project, for example, laterally in front of the support body carrier. It is possible that the support body carrier forms, so to speak, a base for the arms of the chassis. The arms may protrude, for example, in front of a base leg of the support body support.

In the sense of optimal support of the chair on the ground is the following measure. It is expedient if free end regions of the arms protrude laterally in front of the seat surface and / or are arranged on the substrate next to a projection surface of the seat surface.

The chair expediently has at least one foot support surface for supporting a foot of the user.

The at least one foot support surface may be fixed and / or immovable to the chair. For example, the at least one foot support surface may be fixed to a chassis base of the chassis or formed by the chassis base. For example, support plates, support walls or the like as foot support surfaces are conceivable.

The foot support surface is preferably mounted adjustable with respect to the chassis by means of an adjustment. Thus, it can be adjusted ergonomically favorable positions. In particular, it is advantageous if the foot support surface is mounted relative to the seat adjustable. Thus, the position of the foot support surface can be adapted to a user's height. For example, the adjusting device comprises a sliding bearing, in particular a telescopic arrangement. It is understood that expediently, a larger foot support surface can be provided for parking both feet of the user. But it is also possible that separate foot support surfaces are provided for a respective user foot. Furthermore, it is possible that for one and the same foot of the user several, for example two, foot support surfaces are provided, which are, however, spaced from each other, so that the operator or user of the chair can find different ergonomic positions.

The at least one foot support surface may be adjustable between a non-use position and a use position. When not in use, the at least one foot support surface is adjusted, for example, to the support body assembly and / or to a chassis base of the chassis out and is not suitable for parking a foot of the user, while it is unfolded in the use position, for example, for supporting the foot the user is ready.

It is possible for the at least one foot support surface to be arranged, for example, directly on the support body arrangement, in particular the seat support body.

The at least one foot support surface is arranged, for example, on a support body of the support body arrangement, which in turn forms a support body support, for example for the backrest support body and / or the seat support body.

The fixed to the support body assembly or movably arranged at least one foot support surface can be fixed by means of the adjustment device provided for the adjustment of the support body assembly on the support body carrier in several positions. A separate adjustment is not necessary. However, it is possible that the at least one foot support surface is arranged to be adjustable relative to the support body support, for example by means of a telescopic arrangement, in order to allow adaptation to a respective body size of the user in this way.

It is advantageous if at least one, in particular laterally next to an arm of the chassis projecting foot support surface for supporting a foot of the user is arranged on the chassis. The foot support surface can be used, for example, to park the foot. It is advantageous if a plurality of such foot support surfaces are provided, for example on opposite sides of the longitudinal axis of the chair. Thus, the user, when sitting on the seat, his feet comfortably supported on one of the foot support surfaces.

In principle, it is possible that the user of the chair, when sitting on the seat, at any time can park his feet, for example on the chassis or a foot support surface. Especially with children, it can be advantageous if they literally do not get a foot on the ground. For example, it is provided that laterally next to and / or in front of the seat surface of the chair, a closed storage area or foot space remote from the base of the chair is provided in the chair. So when a user sits on the seat, he can not put a foot on the ground, but puts his feet in the footwell or the storage area for the feet.

In the sense of a comfortable handling to the effect that a user sitting on the seat can perform driving movements by repelling himself with his feet on the ground can be the following measure. It is expediently provided that laterally next to the seat surface transverse to the longitudinal axis a free movement space for legs of a user of the chair is provided, wherein in the movement space preferably no support element, in particular no role or no support foot and / or no component of the chassis is arranged. The movement space can be provided for example between laterally in front of the seat protruding arms of the chassis.

It is advantageous if the chair, in particular the chassis, has at least one support leg, which is adjustable with reference to a bearing arrangement between a use position and a non-use position with respect to the chassis base. In the above description, such a support leg has been described as a support foot arranged at a longitudinal distance from the at least one non-steerable roller. Of course, such a support leg can also be arranged in a non-steerable role.

It is further expedient if the chair, in particular the chassis, has at least one support leg which protrudes in the parked on the ground state of the chair before at least one roller of the roller assembly, in particular in front of the at least one non-steerable role. In the parked state or static state, the chair is available to a user for sitting. But the support foot can become inactive, so to speak. It is preferably provided that the at least one support leg or the chair by tilting or pivoting of the chair on the at least one roller, for example, the at least one non-steerable role in a remote from the ground pivot position can be brought, so that the chair on the basis of at least one role the underground can be moved. The support foot is thus so to speak pivoted away from the ground. The handling of the handle is particularly low, which preferably serves as a rocker arm to adjust the chair in the pivot position and then maneuver in the pivot position on the ground.

A per se an independent invention forming measure in connection with the preamble features of claim 1 or the features mentioned above known chairs, but also an advantageous embodiment of Invention or the above above measures provides that the chair arranged above the seat and the backrest surface opposite pivot bearing for a countertop or a holder for a functional element, in particular an electronic device, wherein the worktop or the functional element based on the pivot bearing in a pivoted for use to the seat and the backrest surface, in particular approximately horizontal, use position and pivoted away from the backrest surface and the seat and the free space above the seat increasing non-use position, in particular approximately vertical, are pivotable and a pivot axis of the pivot bearing at right angles or approximately perpendicular to the longitudinal axis of the chair. When the functional element or worktop is pivoted to the inoperative position, it not only releases the space above the seat but also laterally adjacent to the seat (with respect to the longitudinal axis of the chair) so that the user of the chair can lean on both sides Get seat or can get up from the seat. Handling is made easier. The user can sit comfortably on the chair and leave the chair again when the worktop or the functional element are in the non-use position. On the other hand, the worktop or the functional element are convenient to use when they are in the position of use. Insofar as the above measure is regarded as an independent invention, all the individual features illustrated above in connection with the invention explained above, in particular independently of the definition of claim 1, can be realized in the context of the further invention.

A likewise advantageous embodiment of the invention or the above measures, but also a separate idea is the following measure. It is advantageously provided in the chair that the support body carrier has a base leg which is connected to the chassis or forms part of the chassis, wherein a support leg of the support body support for supporting the backrest surface and / or a handle for gripping the chair protrudes angularly from the base leg. Insofar as the above measure is regarded as an independent invention, all the individual features illustrated above in connection with the invention explained above, in particular independently of the definition of claim 1, can be realized in the context of the further invention. The basic idea is that the support body support forms a total of the chair stabilizing and sustainably ausgestaltende component.

From the base leg is expediently still holding leg of the support body support for holding a countertop or a holder for a functional element, in particular an electronic device, from an angle.

The functional element is, for example, a computer, in particular a tablet computer, a smartphone or the like. However, the functional element can also be a plate of a game, in particular a board game, which can be played by the user of the chair. The holder may for example comprise or be a retaining clip and / or a support plate and / or a latching arrangement or the like.

It is preferably provided that the support body carrier has a U-shaped or V-shaped configuration. The support body support is open to the top and can carry the components arranged on it, for example a worktop, a support for a worktop or a functional element, the support body assembly as a whole, but especially a back support body of the support body assembly. If only the support leg is present, it preferably forms an approximately L-shaped configuration together with the base leg.

A geometric configuration provides, for example, that the retaining leg and / or the support leg legs protrude from the base leg at an angle of approximately 80-120 °. Such a construction is, for example, stable and at the same time ergonomically favorable.

It is preferred if the support body carrier has a flat rectangular cross-section. In this case, the flat sides or the sides with the greater extent are preferably the tops and bottoms. The sides with the smaller extent or narrow sides are expediently sides extending between the top sides and bottom sides of the support body carrier. The support body support is therefore resilient and mechanically stable. It is to be mentioned at this point that, of course, other cross sections of the support body support are possible. For example, the support body carrier may have a round cross-section.

It is expedient if the support body carrier made of wood-laminated material and / or wood, especially solid wood. Thus, it is conceivable, for example, that the support body support on the one hand has the wood layer material, which is reinforced for example by wood elements, in particular solid wood elements. But it is also possible that the support body support basically Solid wood is made, wherein for reinforcement purposes or for functional reasons or the like additional plywood components are arranged or mounted on the support body support. The existing wooden support body carrier is preferably glued.

However, the support body carrier can also be made at least partially or entirely of metal and / or plastic.

It is preferred that the support body carrier is in one piece. For example, the support body carrier may consist of a single piece of laminated wood, solid wood, metal, plastic or the like.

Furthermore, it is possible that the support body carrier is formed by a single or single support body support body. Thus, the support body carrier forms, so to speak, a single frame member and / or a single central component of the chair, which protrudes from the chassis and the support body assembly amounts.

However, the support body support can also be formed by a pair of two support body support elements or have such a pairing. For example, two or more support profiles can run parallel and / or next to one another. The support body support elements, in particular the support profiles, each have a base leg, a support leg and a holding leg. The support body support elements, in particular the support profiles, may be interconnected.

It is preferred if the handle protrudes from the support leg of the support body carrier to the rear and / or above. For example, the handle or a handle portion of the handle extends approximately horizontally and projects from the support leg. But it is also possible that the handle or a handle body, so to speak represents a kind of extension of the support leg and thus protrudes at the same angle from the base leg of the support body support as the support leg.

One possibility for realizing the handle is that it is for example formed integrally by the support leg of the support body support or is arranged on the support body support. It is possible, for example, that the support body support, and in particular the free end portion of the support leg are formed in the manner of a handle. For example, a short handle piece, which for example has approximately the length of a hand width, may be provided to form the handle. The handle piece is for example a tubular element, a plastic body or the like, and is connected to the support body carrier, for example glued and / or screwed.

One concept provides that the support body support does not integrally form the handle or handle.

A variant of the invention may provide that the handle is provided on a tubular body. The tubular body is connected to the support body carrier, the chassis or the like. The tubular body may also form a support for the support body assembly, for example a seat back seat body which provides the seat back. Thus, it is possible that the tubular body forms the support body carrier at least partially or completely. The tubular body includes, for example, a metal pipe or plastic pipe. The tubular body expediently has a connecting section extending from the chassis, in particular from the supporting body carrier, upwards, from which a handle section provided for gripping projects at an angle. The handle portion protrudes from the connecting portion, for example, at an angle of about 80-120 °, from.

A concept may provide that the support body arrangement has, so to speak, a seat shell or forms. The support body assembly suitably has a backrest surface and the seat integrally providing support body.

It is also possible that the support body assembly comprises a backrest support body that provides the backrest surface, and a seat surface support body that provides the seat surface. Between the backrest support body and the seat support body is expediently a distance, in particular an adjustable distance.

The backrest support body and / or the seat support body may have a padding. The backrest support body and / or the seat support body are preferably made of wood, in particular of plywood. Preferably, a surface of the respective support body is structured and / or has a wood surface. Of course, a padding may be provided on such a wood-made or wood-bearing support body.

The mutually independent support body, namely the backrest support body and the seat support body are advantageously determined by the adjustment in at least two mutually different relative positions and / or independently of each other on the support body support. The adjusting device has for example latching body, clamping body or the like for latching or jamming of the support body on the support body carrier. For example, one is Clamp, a retaining screw or the like provided. The support body carrier expediently holding contours, such as screw, clamping contours, locking contours or the like are provided which cooperate with the adjustment or where the adjustment for holding the respective support body or the support body assembly as a whole finds a resistance.

It is preferred if the support body arrangement has at least one armrest which is suitable for supporting an arm of the user. The armrest can be formed integrally with, for example, the backrest support body and / or the seat support body. The armrest can be fixedly arranged on the respective support body of the support body arrangement, but also movable by means of a bearing arrangement, so that it is adjustable, for example, when not in use in a non-use position, but can be adjusted for use in a position of use.

The chassis 20 has arms, for example 21 , at the free end of each steerable rollers 25 are arranged. The poor 21 stand from a chassis base 23 of the chassis 20 from. Likewise, stand by the chassis base 23 poor 22 at the free end areas also roles, but not steerable roles 24 are arranged. The roles 24 . 25 form components of a roller assembly 26 , In use, the rollers form 25 front rollers, the rollers 24 rear rollers of the chair 10 ,

In the chair 110 are also steerable wheels in the front of the chair 110 provided, namely steerable rollers 125 , In the back of the chair 110 (based on the position of use or use of the chair) are not two roles, but only a single role 124 provided that like the roles 24 a non-deflectable role. The role 124 is on an arm 122 of the chassis 120 arranged.

The chassis base 23 of the chair 10 and the arms 21 . 22 are by a chassis body 29 formed, so by a single component. The chassis body 29 is configured for example as a metal component, injection-molded component, plastic component or the like.

On the chassis 20 is a support body carrier 30 arranged. The support body carrier 30 is with a base leg 34 with the chassis body 29 connected. From the base leg 34 stand a support leg 32 and a holding leg 36 angular. Between the support leg 32 and the base leg 34 a curved portion or arc portion extends 33 , Between the base leg 34 and the holding leg 36 there is also provided a curved section or curved section, namely a curved section 35 , It is understood that it is also possible in principle that the support legs and the holding leg of a base leg of a support body support according to the invention immediately angled, ie without curvature section protrude.

The support body carrier 30 includes a single and integral support body support 31 , the supporting leg 32 , the base leg 34 as well as the holding leg 36 provides.

On the holding leg 36 can be a telescope body 37 be mounted telescopically, so that a free end portion of the retaining leg 36 on which a countertop 70 is arranged, can be adjusted in height. Of course, it is possible that instead of the telescope body 37 For example, only a panel of the retaining leg 36 is provided or that the worktop 70 directly on the free end of the retaining leg 36 is arranged, so no telescopic body is present.

On the support body support 30 is a support body arrangement 40 provided, on which a user sit down and on which a user can lean on. The support body arrangement 40 includes, for example, a seat support body 41 with a seat 42 that the user can rely on. The position of the seat 42 above a subsoil U, on which the chair 10 is turned off, is based on a setting device 49 adjustable. The adjusting device 49 includes, for example, a Adjusting bracket 43 of which the seat support body 41 projects. The adjustment bracket 43 is with respect to the backbone wearer 30 in various positions, in particular at least two positions, fixable. For example, includes the adjustment bracket 43 a U-shaped or other clamping bracket with which the adjustment bracket 43 on the support leg 32 can be fastened in different positions. For example, on the support leg 32 several locking shots or screw receptacles 38 provided by a corresponding detent, screw or the like, in the adjustment bracket 43 not shown, are penetrable.

The seat support body 41 is preferably made of a plywood material, plastic or the like. The seat comfort is increased by acting on the seat support body 41 preferably a cushion 44 is arranged.

Also, a backrest of the support body assembly 40 is optimally adaptable to the respective height of the user. The one backrest surface 46 is for example a backrest support body 45 provided by means of an adjustment bracket 47 in different positions, preferably at least two positions, on the support body carrier 30 is determinable. The backrest support body 45 Conveniently also consists of a layer material, in particular wood, plastic or the like. On the backrest support body 45 is preferably a cushion 48 arranged, which at least partially the backrest surface 46 provides.

An example is the adjustment bracket 47 a clamping screw 50 shown, preferably in one of the shots 38 can be screwed. Of course, a stepless adjustability would be advantageous in which the adjustment bracket 47 . 43 only with the support body carrier 30 is jammed, for example by means of a rocker arm, clamping lever or the like.

In the chair 110 is made a basically similar configuration, ie the support body assembly 40 is on the support body carrier 30 adjustable in several positions. Instead of the support body arrangement 40 but could also be a support body assembly with a support body 141 be provided, which integrally provides both a backrest surface and a seat surface. The supporting body 141 is designed, for example, in the manner of a seat pan. The supporting body 141 suitably also consists of a plate material, in particular plywood. The supporting body 141 can on the basis of the adjusting device 49, for example, based on a not visible in the drawing adjustment bracket in the nature of the adjustment bracket 43 . 47 in different positions on the support body carrier 30 be attached.

In the use position G is the worktop 70 at least partially up to the seat 42 in front. In particular, a surface of the worktop 70 approximately horizontally oriented or inclined flat, allowing the user of the chair 10 . 110 also the worktop 70 for example, in the manner of a desk top can use. In the non-use position N, however, is the worktop 70 from the seat 42 So, for example, is essentially vertical, allowing the user of the chair 10 . 110 comfortable from the seat 42 can get up or get on the chair 10 . 110 can put.

In the chair 10 the user can if he is on the seat 42 For example, his feet are on his arms 21 Off.

In the chair 110 is a more comfortable "Fußabstellkonzept" realized. For example, on the base leg 43 poor 121 arranged at the free end portions of the steerable rollers 125 are rotatably mounted. The poor 121 include, for example, plate-like bodies 128 that are sideways in front of the basic thighs 43 protrude. The plate-like body 128 each have a foot support surface on their surfaces 180 on which the operator or user of the chair 110 can put his feet. From the plates 128 away covers a cover 127 that has castors or steerable castors 125 covers the upper side, so to speak. Thus, the user of the chair gets 110 not accidentally in the steerable wheels 125 ,

Between the poor 21 . 22 of the chassis 20 There is a relatively large clearance or foot clearance available on the seat surface 42 of the chair 10 sitting users can push off with their feet on the underground U. But there are situations where this is not desired. For example, if a child's chair 10 . 110 It may be desired that the child does not use the chair without the help or will of the supervising person 10 . 110 can move on the ground. In this case, the foot support surfaces 180 in the chair 110 helpful. The foot support surfaces 180 hinder a user who is on the seat 42 of the chair 110 sitting down, his feet on the ground U turn off or repel the underground U.

Instead of the worktop 70 can also be a holder 72 be provided, with a functional element 73 on the chair 10 . 110 releasably attachable is. For example, the holder 72 a clamp holder. The functional element 73 preferably has a plate-like shape. For example, the functional element 73 a tablet computer, smartphone or the like. It is advantageous if the holder 72 based on the pivot bearing 71 pivotable between the use position G and the non-use position N, so that on the holder 72 located functional element 73 is also pivotable between these two positions.

The support body carrier has a cross-sectionally approximately U-shaped shape. The two from the base leg 34 protruding leg, namely the support leg 32 as well as the holding leg 36 , but are not perpendicular to the base leg 34 but at a larger angle, so that their free end portions have a greater distance from one another than their end portions at the curvature portions 33 . 35 ,

Furthermore stands the support leg 32 further from the base leg 34 as the holding leg 36 , The support leg 32 Accordingly, has a large adjustment for the backrest support body 45 and the seat support body 41 , in a correspondingly greater distance from the substrate U on the support body carrier 30 are definable. Thus, the chair 10 . 110 also suitable for larger people. However, even children, especially toddlers, the chair 10 . 110 optimal use, because the support body assembly 40 also close to the base leg 34 is adjustable, so that the distance, for example, the seat 42 to the underground U is adjustable to a small degree or suitable for small body sizes.

Now it is possible in principle, for example, at the free upper end portion of the support leg 32 a handle is arranged to the chair 10 . 110 easy to maneuver on the ground. In particular, the non-deflectable roles 24 . 124 advantageous because they follow the steering movements of the user accordingly. Furthermore, the chair can 10 . 110 via the respective non-deflectable roller or roller arrangement 24 . 124 be conveniently tilted so that the front steerable rollers 25 . 125 stand out from the ground and the chair 10 . 110 even easier to maneuver. The steerable wheels 25 . 125 However, in practice in such steering movements hardly an obstacle. The steerable wheels 25 . 125 can change the steering movements of the chair 10 . 110 consequences.

The steerable wheels 25 . 125 are expediently orthogonal to their respective axes of rotation, with which they roll on the ground U, rotatably mounted on the chassis 20 . 120 stored

A tilting movement and a maneuvering of the chairs 10 . 110 is facilitated by the following measure:

On the support legs 32 the chairs 10 . 110 is each a handle 60 arranged far in front of the upper edge, so the edge which is farthest from the underground U, in front of the backrest surface 46 protrudes upward.

The handle 60 has a handle body 61 on, in particular a tubular body 66 that with a connection section 62 with the support leg 32 of the support body carrier 30 connected is. There are, for example, for connecting the handle body 61 with the support body carrier 30 screw 67 intended. Consequently, so is the handle 60 firmly with the respective base frame or the support body support 30 and thus ultimately with the chassis 20 . 120 connected.

At this point it should be mentioned that the support body carrier 30 with his base leg 34 a chassis base 23 of the chassis 120 represents, of which the arms 121 . 122 protrude. In the chair 10 is an equally strong connection between the support body support 30 and the chassis 20 given by the base leg 34 with the chassis base 23 is firmly connected. Consequently, so is the handle 60 with the respective chassis 20 . 120 firmly connected, allowing steering movements or handling movements, the handle 60 be carried out directly on the chassis and thus on the non-steerable rollers 24 . 124 impact.

The connecting section 62 goes with a bow section 63 in a handle section 64 above. The handle section 64 runs in the position of use, ie when the operator usually takes the chair or when the chair 10 . 110 on the underground U is about horizontal or slightly inclined, which is ergonomically favorable.

At the handle section 64 is advantageous a handle 65 provided, for example, a rubber coating, a cork casing or the like.

It can be seen in the drawing that it is advantageous in a chair according to the invention, if, as in the embodiment in the lower position of the backrest supporting body 45 if this furthest to the roller assembly 26 is at least 1.5 times, even about 1.7 times to 2 times the distance of the handle section 64 to the footprints of the roller assemblies 26 . 126 exists, in particular to the footprints of the non-steerable roles 24 . 124 , so that favorable leverage ratios are given. In particular, the handle portion is 64 even after behind, so from the seat 42 turned away, in front of the non-steerable rollers 24 . 124 before, which creates particularly favorable leverage.

At this point it should be mentioned that the chair 10 . 110 especially safe on the ground. The roles of role arrangements 26 namely, the non-deflectable rollers 25 . 125 stand in front of the projection surface of the chair 10 . 110 outward. In particular, they are laterally next to the seat 42 with respect to a longitudinal axis L of the chair 10 . 110 provided, so have a broad track so to speak.

Alternatively or in addition to the roles 25 . 125 but could also support feet 27 be provided (in 2 indicated), with which the chair 10 . 110 can be lowered on the underground U. The support feet 27 can with swivel joints 27a or other bearings movable on the chassis 20 . 120 be stored so that you are in a non-use position where they are not, for example, in front of the rollers 25 . 125 protrude and / or not to the underground U from the chassis base 23 stick out, can pivot.

But it is also possible that instead of roles 25 . 125 the support feet 27 or support feet in the type of support feet 27 are provided. The roles 25 . 125 are not necessary.

Consequently, with the roles 25 . 125 or alternatively or additionally provided support feet 27 support elements 28 present, which are arranged at a great distance to the longitudinal axis L and, moreover, a large distance to the non-deflectable rollers 24 . 124 with respect to the longitudinal axis L.

For a stable hold of the chair 10 also ensures the measure that the non-steerable roles 24 have a larger track width than the steerable rollers 25 and / or the support feet 27 , hence the support elements 28 , Transverse to the longitudinal axis L is thus the risk of tilting of the chair 10 thereby reduced.

Furthermore, it is advantageous that the rollers 25 . 24 a large longitudinal distance to the front or rear Längsendbereich the seat 42 exhibit. For example, the roles have 25 a longitudinal distance LA to the front edge of the seat support body 41 , The non-steerable rollers 24 have a longitudinal distance LB to the back of the backrest support body 45 and in particular to the backrest surface 46 , Thus, therefore, is the non-deflectable role 24 . 124 rearward with respect to the longitudinal axis L in front of the support body assembly 40 in front.

In terms of a favorable maneuverability, it is when, as in a chair according to the invention generally advantageous, the non-steerable roles 24 . 124 in a space or between the backrest surface 46 and the handle section 64 are arranged.

In principle, in a chair according to the invention is also that the handle relative to the base frame or chassis 20 is arranged adjustable. So could for example for the screws 67 an arrangement with several screw holes on the support body carrier 30 and / or on the handle body 61 be provided to the handle body 61 in different longitudinal positions relative to the support body carrier 30 to fix. Furthermore, a sliding bearing, a clamp connection or the like between the support body carrier 30 and the handle 60 possible. For example, the connection section could 62 concerning the supporting leg 32 be telescopic.

Furthermore, it is possible that in a chair according to the invention, the handle body or handle is attached directly to the chassis. For example, it is conceivable that between the poor 22 , thus, for example, on the chassis base 23 of the chair 10 an attachment for the handle body 61 is provided. For example, this could be there with the chassis body 29 be firmly connected, in particular welded, glued, screwed or the like.

At the in 4 and 5 represented chairs 201 . 310 some of the same or similar components are present as in the chairs 10 . 110 ,

The chairs 210 . 310 show chassis 220 on which support body support 230 are arranged. On the support body supports 230 are support body arrangements 240 . 340 kept adjustable so that the chairs 210 . 310 can be adapted to the respective body sizes of the users. In particular, the chairs are suitable 210 . 310 for small children or smaller children than the chairs 10 . 110 ,

The chassis 220 have non-steerable rollers 224 on, which represent in the direction of travel, so to speak, rear rollers and the rollers 24 . 124 functionally equivalent. The non-steerable wheels 224 are at arms 222 Arranged by a chassis base 223 protrude. The poor 222 functionally correspond to the poor 22 and are arranged similarly.

Similar to the arms 21 of the chassis 20 stand with the chassis 220 poor 221 but at the free end of which no castors are arranged, but support legs 227 , The support feet 227 are fixed, but could be similar to the support feet 27 be adjustable by pivot bearings, sliding bearings or the like. Especially can be used for leveling at least one of the support legs 227 be provided with a longitudinal adjustment. The support feet 227 form supporting elements 228 located at a longitudinal distance with respect to a longitudinal axis L of the chairs 310 . 210 to the non-steerable rollers 224 are arranged.

At this point it should be mentioned that the non-steerable roles 224 the only roles or the only pair of roles of the chairs 210 . 310 or the only pair of rollers before their role arrangements 226 represent.

In contrast to the support body supports 30 the chairs 10 . 110 are the support body carriers 230 approximately L-shaped and have no holding leg on which a functional element is arranged or mounted.

The support body supports 230 have support body support body 31 on, which have a flat rectangular cross-section.

From basic thighs 34 the support body carrier 230 that with chassis bodies 229 the chassis 220 are firmly connected, standing support legs 232 angularly from, for example, at an angle of about 90 ° to 120 °, preferably about 100 ° to 110 °, from. Between the respective support legs 232 and the base leg 234 is a curvature section 233 intended. The support body carrier body 231 forms a kind of integral frame. The support body carrier body 231 has a flat rectangular cross-section, which makes it particularly stable.

At a free end region of the respective support body carrier 230 is a handle 260 arranged, in principle, the handle 60 corresponds, but a handle body 261 has, the connecting portion 262 shorter than the connecting section 62 , The support legs 232 are in fact further from the base leg 234 off as the support legs 32 from the base leg 34 , The longitudinal extension of the support leg 232 is significantly larger than the longitudinal extent of the base leg 234 , On the one hand, this enables the support body arrangements 240 . 340 in a larger adjustment adjustable on the support body support 230 , in particular the support leg 232 , are stored. On the other hand, the connecting portion 262 be relatively short, so that nevertheless the handle section 64 far away from the underground U and accordingly the handle 65 is comfortable to touch.

At this point it should be mentioned that of course the support body carrier 230 an even longer from the chassis 220 protruding support leg 232 can have. Such a configuration is particularly advantageous when the support body carrier 230 integrally a handle 360 forms or has (dashed in 5 shown). For example, an upper end portion of the support leg 232 stand out angularly and a handle section 364 form. Furthermore, this is the adjustment for the support body arrangements 240 . 340 increased.

The upstanding and from the underground U far away handle section 364 or 64 Also allows for convenient handling when near the non-steerable rollers 224 support legs 327 are arranged. The support feet 327 close to the non-steerable rollers 224 are arranged allow, together with the support feet 227 that the chair 310 in its position of use exclusively on support legs and not on wheels. As a result, he is safer off the ground, which is particularly advantageous for use by toddlers. Nevertheless, the handling is easily possible, namely, for example, the chair 310 about the non-steerable rollers 224 is adjusted in a swivel position ST (indicated by dashed lines), in which the chair 310 about the non-steerable rollers 224 tiltable or pivotable, so that ultimately the support feet 327 lift off the ground U and the chair 310 on the underground U based on the roles 224 can be rolled.

Accordingly, it is advantageous that on seat support bodies 241 . 341 the support body arrangements 240 . 340 Supporting sheet 281 . 381 are arranged, the foot support surfaces 280 . 380 provide. When the support body arrangements 240 . 340 based on their adjustment 249 relative to the support leg 232 be adjusted makes the respective foot support surface 281 this adjusting motion with, so that he always in optimal position to a seat surface 242 . 342 the seat support body 241 . 341 is.

The convenience it serves that on the support surface support bodies 241 . 341 one upholstery each 244 . 344 is optionally provided.

For back support serve in the support body arrangements 240 . 340 Backrest support body 245 . 345 , preferably each a pad 248 . 348 and in any case a backrest surface 246 . 346 for the user of the chair 210 . 310 provide.

From the backrest support bodies 245 . 345 are preferably integral armrests 255 . 355 starting to support the arms of the respective user of the chair 210 . 310 serve. The armrests or armrest body 255 . 355 preferably extend to a front end portion or free end portion of the seat bottom support body 241 . 341 so that on the chair 210 . 310 seated person, especially a toddler, is protected against falling out.

In the chair 210 is a worktop 270 pivotable and / or releasable on the support body assembly 240 stored. For example, at a free end of the armrest 255 or one of the armrests 255 a bracket 274 arranged in which a plug-in projection or bearing projection 275 can be inserted, which of the functional element or the worktop 270 projects. For example, the bearing projection 275 designed in the manner of a journal, in a bearing receptacle of the brackets 274 engages, making a total of one pivot bearing 271 is formed. On the basis of the pivot bearing 271 can the worktop 270 between the in 4 illustrated position of use in which they frontally in front of the backrest surface 246 stands, and one of the area of the support body assembly 240 are swung out or from a front side of the seat 241 pivoted away tilted non-use position. The pivot axis S2 is preferably a vertical pivot axis (in the position of use of the chair 210 ).

The foot support surface 281 is based on a bracket 282 with a basic body 251 and / or with the seat support body 241 connected. The holder 282 includes a telescopic part 283 which with respect to the seat 241 and / or the seat support body 241 is stationary, as well as a telescope part 284 , which concerning the telescope part 283 telescopic, therefore longitudinally displaceable, and with the foot support surface body 281 connected is. Thus, the foot support surface can 281 by the telescope arrangement passing through the telescopic parts 283 . 284 is formed, with respect to the seat 242 be adjusted, ie a distance of the foot support surface 280 to the seat 242 is adjustable.

The basic carrier 251 is for example for holding the support surface support body 241 and the backrest support body 245 intended. For example, the basic carrier 251 using an adjustment bracket 243 on the support leg 232 held and in particular in several steering positions with respect to a longitudinal extension of the support leg 232 adjustable. This concept is subsequently related to the chair 310 more clear.

The adjustment bracket 243 for example, extends from the armrests 355 integrally providing backrest support body 245 away and is off the support leg 232 penetrated. A clamping screw or the like, for example in the manner of the clamping screw 50 , is not shown in the drawing of the simplification. With such a clamping screw or a locking device or the like, the adjustment holder 243 in several longitudinal positions with respect to the longitudinal extension of the support leg 232 be fixed to the same stationary.

At the base carrier 251 the support body assembly 340 is the foot support surface 381 fixedly disposed and is integrally formed by this. For example, the basic carrier 351 one with the adjustment bracket 43 connected and along the support leg 232 extending thighs 387 on, with a curvature section 386 in a thigh 385 goes over where the seat support body 241 is held.

From the thigh 385 there is a thigh 382 from which in turn angled the foot support surface 381 projects. Between the thigh 382 and the foot support sheet 381 are curvature sections 383 . 384 intended. The foot support surface 381 and the thigh 385 run parallel to each other. Thus, therefore, the foot support surface is 381 stepped relative to the seat support body 341 arranged.

In the chair 310 is exemplified for other chairs according to the invention that a foot support surface 481 , For example, a stirrup or the like, may be provided, for example, based on a pivot bearing 482 or another bearing, for example a multi-joint bearing or sliding bearing, between a use position GS and a non-use position NS is adjustable. In the use position GS is a foot support surface 380 in front of the seat 242 before, so the user of the chair 310 his feet also on the foot support surface 380 can turn off. In the non-use position NS, however, is the foot support bracket or the foot support surface 381 from a front or free end side of the seat support body 341 pivoted away, for example, down as shown in the drawing, so that he the free accessibility of the chair 310 not obstructed from the front. Of course, it is advantageous if the adjustable foot support surface body 281 . 481 locked in their respective position of use or use position, locked, clamped or fixed in any other way stationary.
