Description

[0001] The invention relates to a piece of seating furniture, in particular a high chair for children according to claim 1.

[0002] High chairs for children (children's chairs) have been around for a long time and come in various designs. Typically, such high chairs consist of a frame with a pair of front legs and a pair of rear legs (or alternatively, for example, just two legs that are widened at their base to ensure stability) and a seat with a seat cushion and a backrest. Additional features may include armrests, a footrest, a tray, and the like. The frame (with or without the seat) may be foldable to allow for both an open position and a more compact folded position.

[0003] The seat can be in a fixed position relative to the frame or adjustable in height, whereby either the entire seat is adjusted or individual components such as the seat surface and / or the backrest and / or the footrest (which can then be adjusted independently of each other). In the prior art, it is also common practice (in height-adjustable high chairs) to provide a certain number of predetermined positions (height positions) for the adjustable components, for example, by creating holes at suitable locations on the frame and (retractable) pins on the component to be adjusted.

[0004] An adjustable child seat is known, for example, from DE 690 09 806 T2. According to DE 690 098 06 T2, two pins (one on each side of the child's chair) are provided for height adjustment. These pins can assume different, discrete positions in a guide track, thus allowing the highchair to be adjusted in height. Solutions based on the same principle are known from US 5 238 292 A and US 4 722 570 A. In US 5 238 292 A, locking elements are provided that can be engaged with corresponding ribs, thus also allowing the height to be adjusted.

[0005] US 4,722,570 A describes hook elements that can interact with locking elements to enable discrete height adjustment. Overall, these solutions are considered comparatively complex in design and handling, and especially comparatively inflexible, according to the prior art.

[0006] It is therefore an object of the invention to propose a piece of seating furniture, in particular a children's chair, preferably a high chair for children (children's chair) with an adjustable support device for supporting a part of a child's body, wherein an adjustment of the height should be made possible in a simple and in particular flexible manner.

[0007] This problem is solved by a piece of seating furniture, in particular a high chair according to claim 1.

[0008] In particular, the problem is solved by a piece of seating furniture, especially a children's chair, preferably a high chair for children with a height-adjustable support device for supporting a part of the child's body and / or an external object, such as a drinking bottle or a toy, wherein the height adjustment device includes a locking device that causes a locking of a set height, at least partially, in particular predominantly, by means of a force-fit (in particular by an interference fit and / or a clamping).

[0009] According to a further optionally independent aspect (which, however, can be combined in particular with the above aspect concerning force transmission), the above task is solved in particular by a piece of seating furniture, in particular a children's chair, preferably a high chair for children with a height-adjustable support device for supporting a part of the child's body, comprising a height adjustment device configured for stepless height adjustment of the support device.

[0010] A key concept of the invention is to lock a specific height (of a height-adjustable support device) at least partially (in particular predominantly) by means of a force-fit (or friction-fit). In a force-fit, a normal force is exerted between the surfaces to be locked against each other. Overcoming the locking mechanism is only possible if an applied force exceeds the counterforce caused by static friction. In contrast to a force-fit, a positive-fit involves at least two parts to be joined interlocking. Therefore, in a positive-fit, the parts to be joined cannot separate from each other, even without or with an interrupted force transmission. In other words, in a positive-fit connection, one part to be joined obstructs the other. Under operating load, compressive forces act normally, i.e., perpendicular to the surfaces of the parts to be joined.Such positive locking mechanisms are described, for example, in US 4 722 570 A, US 5 238 292 A and DE 690 09 806 T2.

[0011] It is not strictly necessary that the intended frictional connection alone be able to maintain the locking mechanism (although this is preferably the case). In any event, the locking device is configured such that a lock can only be maintained (under load) if the frictional connection is also active. In other words, a lock is only maintained if the frictional connection is active, and it is not maintained if the frictional connection is at least conceptually removed (or the holding force of the frictional connection is at least conceptually disregarded). This should apply at least to the state of the respective support device in which the support device's own weight is acting.Insofar as the support device is or includes a seat (and / or a footrest), an additional load of preferably at least 5 kg, and more preferably at least 10 kg (representing the child's weight), can be taken into account. An upper limit for the weight to be added (simulating the child) to the support device can be ≤ 60 kg, preferably ≤ 40 kg. For example, in a range of 5 kg to 60 kg, the locking mechanism should at least partially ensure that the locking mechanism does not hold (in the sense that, without the locking mechanism, the locking mechanism would not hold, at least in sections of this range). Preferably, the force that can be compensated by the locking mechanism (in the locked state) is ≥ 50 Newtons, more preferably ≥ 200 Newtons, and even more preferably ≥ 300 Newtons.The locking mechanism is primarily intended to be achieved through frictional engagement, particularly when at least 50%, preferably at least 80%, of a holding force is applied (especially under the circumstances mentioned above, for example, regarding the additional weight of a child sitting in the chair). The locking mechanism is fully effective when the entire force can be compensated for by the frictional engagement (or when the locking mechanism can maintain the locking position).

[0012] The height adjustment device is preferably configured such that adjustment is possible within a height difference (in the vertical direction) of at least 5 cm, preferably at least 10 cm, and even more preferably at least 15 cm. This height adjustment is preferably stepless if any height value can be set within this height difference (or at least height values ​​that are ≤ 2 mm apart, in particular ≤ 0.5 mm apart). In principle, a first height adjustment range can also be provided in which the height is steplessly adjustable, and a second height adjustment range in which only discrete height adjustment is possible. However, in one embodiment, stepless height adjustment can be enabled across the entire height adjustment range (of the respective support device).If, in addition to a continuously adjustable height range, there is also a discretely adjustable height range, the height difference of the continuously adjustable height range (in the vertical direction) is in particular at least 2 cm, more preferably at least 5 cm, and even more preferably at least 10 cm.

[0013] In this embodiment, the locking device can be configured such that it achieves the locking of the set height, at least partially, and in particular predominantly, by means of an interference fit and / or a clamping mechanism. An interference fit is understood to be, in particular, a configuration in which a force (for example, by a spring) acts in the direction of one or more contact surfaces, so that the adhering surfaces are pressed against each other. For example, a projection or pin (or the like) can be pressed into a corresponding recess. A clamping mechanism (or a corresponding clamping device) is understood to be, in particular, a device that acts in such a way that an increase in the applied force (for example, when a child climbs onto the seating furniture, in particular the highchair) causes an increase in the force due to the frictional force (comparable to a wedge wedged under a door gap).Such measures enable safe application in a simple way.

[0014] The support device may include a seat and / or a backrest and / or a footrest and / or an armrest and / or a storage surface (for drinking cups and the like).

[0015] The locking device can comprise (at least) one locking groove and at least one locking element that can be inserted into and removed from the locking groove. The locking element is preferably secured in the locked position within the locking groove by an interference fit and / or a clamping mechanism. Such a configuration allows for simple, stepless adjustment of the locking mechanism. The locking groove can be located on a main body (e.g., frame) of the seating furniture, particularly a high chair, and the (at least one) locking element on the support structure, or vice versa. The interchangeability of the arrangement of components that can be connected to one another by friction also applies in principle to other possible embodiments of the invention (as described, for example, below).

[0016] A locking mechanism can preferably be engaged or disengaged by rotating one or more of the locking elements and / or by a translational movement of one or more of the locking elements. For example, the locking element can be rotated into the locking groove to effect a locking action. This allows for a simple locking mechanism.

[0017] Preferably, the actuating element is pre-tensioned, particularly in the direction of a locking position (or in a direction in which the actuating element is forced into the locking position by a pre-tensioning force). This further simplifies handling.

[0018] In one embodiment, a locking mechanism can be engaged and / or disengaged by rotating an actuating element and / or by a translational movement of an actuating element. An actuating element is understood to be, in particular, a handling device (e.g., comprising a handle) that is accessible from the outside so that a user can grasp it (to engage or disengage the locking mechanism). Such a handling device can, for example, be arranged in a central area of ​​the seating furniture, especially a high chair. Optionally, at least two or more locking devices can be actuated via one and the same actuating element (or handling device) (so that a locking mechanism is engaged or disengaged). The actuating element and the locking element can be operatively connected to each other via a connecting device (which may be translationally or purely translationally movable).

[0019] In one specific embodiment, the actuating element is rotatable and arranged such that it drives a (translationally movable) connecting device, which in turn rotates one (or more) locking elements to engage or disengage the locking mechanism. Such a configuration allows for a simple method of engaging and disengaging the locking mechanism.

[0020] In a preferred embodiment, a preload device, in particular a spring, is provided, preferably acting in the direction of a locked position. Alternatively, a spring device (possibly a further spring device) can also be provided, acting in the direction of an unlocked position. If a preload device, in particular a spring, is provided that acts in the direction of a locked position, a locking mechanism can be established and maintained in a simple (and safe) manner. In particular, such a preload device, in particular a spring, provides a predefined force that does not depend on the specific usage situation (e.g., the child's weight). Preferably, the height adjustment is positively guided. This simplifies handling. Such positive guidance can, for example, comprise a rail and / or groove and / or cam.

[0021] In one specific embodiment, a guide groove is provided for guiding a height adjustment mechanism. The guide groove is preferably formed, at least partially, by the locking groove described above (or vice versa). In particular, the guide and / or locking groove is designed such that the locking element described above can slide in the guide or locking groove when not locked.

[0022] Alternatively or additionally, a further sliding element can be provided, which can slide in the guide or locking groove (for guiding or controlling the height adjustment). The sliding element is provided in addition to the locking element. The sliding element can be designed as a plate (possibly concave, especially cylindrical segment-shaped) that can be moved accordingly in the groove. Particularly in the locked position (possibly also in the unlocked position), the locking element preferably penetrates the sliding element (especially an opening in it, which can, for example, be slot-shaped). Overall, this simplifies handling.

[0023] If, in general, a locking element is provided that can be inserted into and removed from the locking groove, this does not necessarily mean that the locking element must be able to be completely removed from the locking groove (which may be the case), but it is sufficient in this sense if the locking element can be at least partially removed from the locking groove (in particular in the sense that a distal end of the locking element can be moved further away from a groove base).

[0024] A combined guide and locking groove allows for easy adjustment and locking in a structurally simple design.

[0025] The locking mechanism can be arranged and configured in such a way that gravity (of the support device itself and, if applicable, of a child positioned on the support device) at least assists the locking action. For example, gravity can be directed (redirected) in such a way that it increases the normal force between surfaces in static friction.

[0026] In one embodiment, the locking device has two locking elements (preferably rotatable in opposite directions). The two locking elements can optionally engage in the same recess (e.g., a groove). The two rotatable locking elements are preferably guided (for example, by a common contact surface at the proximal ends of the locking elements) such that they can only be rotated together. Preferably, the two locking elements are mounted on a common axis.

[0027] In general, one or more locking elements can be mounted on the axis of rotation, which is fixed relative to a main body (e.g., frame) of the seating furniture, particularly a high chair. If two locking elements are provided (especially those rotatable in opposite directions), it can be provided that a first locking element enables (at least predominantly) a locking action against downward movement, and a second locking element enables (at least predominantly) a locking action against upward movement. Furthermore, the rotation of the locking elements (for example, by rotating them towards each other) can generate an additional force (e.g., due to spreading) that further improves the locking mechanism.

[0028] The one or more locking elements can be wedge-shaped in a cross-section (especially radial section) or possibly planar.

[0029] Each support structure can be equipped with several locking devices, preferably two, in particular one on each side of the seating furniture, especially a high chair. This ensures reliable locking.

[0030] In a preferred embodiment, the height adjustment and / or locking of the set height and / or releasing of the locking of the set height can be performed with one hand. Preferably, both the height adjustment and the locking of the set height, as well as the releasing of the locking of the set height, can be performed by grasping and operating a (single) handle. For example, the height adjustment can be achieved by raising or lowering (or allowing the handle to lower) the handle (i.e., generally, possibly by a translational movement), and the locking of the set height or the releasing of the locking of the set height can be achieved by rotating the handle. The handle itself is preferably formed in one piece or monolithically. Furthermore, the handle can be centrally located. The handle can also have a concave outer surface (for gripping).The handle length can be at least 5 cm, preferably at least 10 cm, and / or at most 30 cm, preferably at most 20 cm. This significantly simplifies the handling of the child seat.

[0031] At least one or more locking elements are preferably rotated downwards (at least in the locked position, and optionally in all possible positions). This means that a load acting, for example, on the axis around which the respective locking element pivots, leads to a further extension (upward pivoting) of the locking element, so that the locking element pivots further outwards and thus increases the holding force (friction force). This allows the effect of a load to be used to increase the locking force in a simple manner.

[0032] According to the invention, a piece of seating furniture, in particular a high chair, is proposed, which has a height-adjustable component, wherein the height adjustment can preferably be locked (fixed) by a clamping device (clamping element). The clamping device (in particular, wedge-shaped) can be arranged on a main body of the seating furniture, in particular a high chair (e.g., frame), and can be designed to engage with the height-adjustable component – ​​or vice versa. This allows the locking device to be moved into a locking position, in which relative movement between the main body of the seating furniture, in particular a high chair, and the height-adjustable component is prevented, or into a released state, in which such relative movement is permitted. A transition between the locked state and the released state is preferably achieved by rotation, but can also be achieved translationally.Preferably, a clamping device or a locking element is pre-tensioned in the direction of the locking state, for example by a spring or other (suitable pre-tensioning device).

[0033] In a preferred embodiment of the invention, a relative movement is guided between the main body of the seating furniture, in particular a high chair, and the height-adjustable component, such that the relative movement follows (or must follow) a predetermined trajectory. Continuous (stepless) positioning is possible along this trajectory. A groove can be provided on the element (either the main body or the height-adjustable component) that does not include the spring element (or the clamping device) to serve as a guide. In the locked position, the locking element (or the clamping device) can engage with an inner surface of the groove. Preferably, in the released position, the locking element (or the clamping device) can be moved in the groove without being blocked.

[0034] In a preferred embodiment of the invention, the locking element (or clamping device) can preferably transition from a released state to a locked state by rotation. The rotation preferably occurs in such a direction (or direction of rotation) that a force acting in the direction of gravity (or along a guide device, such as a guide groove) at least partially (or possibly completely) effects the engagement (the locking). Alternatively or additionally, two locking elements (clamping devices) can optionally be provided, which may be rotatable in different directions, so that for every force (with a component in one direction of possible movement), at least one of the locking elements (or clamping devices) effects a locking action.

[0035] In general, it is possible that the seating furniture, in particular the high chair or the height-adjustable component, is equipped with two or more locking elements (clamping devices or locking devices) or corresponding pairs of locking elements (or clamping devices) that can be released and / or moved into the locked state by a common mechanism.

[0036] Further embodiments of the invention are set out in the dependent claims.

[0037] The seating furniture, particularly the highchair, may consist of a frame, possibly with a pair of front legs and a pair of rear legs (or alternatively, for example, only three or only two legs, which may be widened at their lower ends to ensure stability), and a seat with a seat surface and, optionally, a backrest. Additional elements may include armrests, a footrest, and / or a tray. The frame (with or without the seat) may be foldable to allow for both an open position and a more compact folded position.

[0038] The invention encompasses not only a height adjustment (although the present invention is particularly advantageous for height adjustment, as it is especially important here that the child or other objects can be positioned as precisely as possible), but also, more generally, an adjustment of another position of the support device, in particular a depth adjustment (i.e., in particular, an adjustment of the support device further forward or further backward). Therefore, in the above and following, "height adjustment" can be replaced by "height and / or depth adjustment" wherever the orientation of the respective adjustment option is not (or at least not crucially) important (as is the case, for example, when utilizing gravity). Furthermore, terms such as "upwards" or "downwards" can then be replaced by "forwards" or "downwards," respectively.

[0039] In contrast to the prior art, stepless height adjustment is now possible, not just discrete (predetermined) positions. This reduces material and manufacturing costs, as separate elements such as detents or similar features are not required for each predetermined position (as in the prior art). Overall, this enables a height adjustment device that allows stepless height adjustment of an adjustable component and can reliably hold a specific position, while keeping manufacturing costs comparatively low.

[0040] The invention is described below using an exemplary embodiment, which is explained in more detail with reference to the figures. These show: Fig. 1a schematic front view of a high chair according to the invention with partially transparent surfaces; Fig. 2 individual elements of the high chair according to Fig. 1 ; Fig. 3 individual elements of the high chair according to Fig. 1 in an oblique view; Fig. 4 individual elements of a high chair according to the invention in a side view and a first position; Fig. 5 the elements according Fig. 4 in a side view and a second position; Fig. 6 the elements according Figs. 4 and 5 in the position according to Fig. 5 and an oblique view; and Fig. 7 individual elements of the high chair according to the Figs. 4 to 6 .

[0041] In the following description, the same reference numbers are used for identical and equivalent parts.

[0042] Fig. 1 shows a high chair 10 with legs 11, a seat 12, a backrest 13, a footrest 14 and a tray 15.

[0043] The seat 12 and the footrest 14 are adjustable (independently of each other) in height relative to the legs 11. The height adjustment mechanism is analogous for the seat 12 and the footrest 14, so only the height adjustment mechanism of the seat 12 will be explained in detail below.

[0044] During adjustment, the height adjustment of the seat surface 12 is guided by means of a (guide) groove 29.

[0045] The seat surface 12 generally includes a (symmetrical) locking device 20. The locking device 20 has an actuating device (lever) 21 and a stabilizing strut or housing 27. On each side of the locking device, there is also a force transmission device (rod) 23, a spring 24, a contact element 28 (at the end of the force transmission device 23), which may be designed as a pressure plate, and two locking elements 25 or clamping devices 25 (see Figs. 2 and 3 ) provided.

[0046] The spring tensions the locking elements 25 against each other in a locked position, whereby these locking elements 25 engage with a (associated) leg 11 of the highchair 10, specifically with a groove 29 provided therein. According to the embodiment, this groove is formed by the aforementioned (guide) groove 29. When the locking device 20 is in a locked position, the actuating device 21 can be designed (at least substantially) parallel to the housing 27 and may optionally form a flush surface with this housing.

[0047] The actuating device 21 has a (round) central section 22 and (in this case, two) recesses 22a, wherein, in the locked state, each recess 22a engages with one of the force transmission devices 23 (rods). The locking elements 25 (on each side) are pivotably mounted on the housing 27 about a common axis 26.

[0048] The locking device can be moved from a locked state to a released state by rotating the actuating device 21, thus moving the force transmission device 23 outwards (since the force transmission device 23 can then no longer engage with the recesses 22a). This also moves the contact device (pressure plate) 28, which is located at a distal end of the respective force transmission device 23, outwards and presses against the proximal ends of the locking elements 25. Due to this movement, the locking elements 25 pivot about their (common) axis 26 against the tension force of the spring 24 and thus release from the leg 11.

[0049] By rotating the actuating device 21 (back to its original position), the spring 24 can pivot the locking elements 25 back so that they are again locked to the leg 11, since in this state the force transmission device 23 is again engaged with the recesses 22a. This allows one of the locking elements (clamping devices) 25 to engage with the corresponding groove 29 in the event of an upward or downward force, thus preventing the seat surface 12 from moving in the direction of the force.

[0050] Fig. 4 shows a side view of individual elements of a high chair according to the invention. This can be arranged according to the Figs. 1 to 3 be trained so that Fig. 4 also as an illustration of further details of the high chair according to the Figs. 1 to 3 can be viewed. In the Figs. 1 to 3However, the sliding plate 30 is not shown. This sliding plate 30 can optionally be included in the embodiment according to the Figs. 1 to 3 be provided for (or not). Conversely, it is indeed in the Figs. 4 to 7 The sliding plate 30 is shown. In particular, this sliding plate is, however, in the embodiment according to the Figs. 4 to 7 only optional.

[0051] In the Figs. 4 to 6 It can be seen that by rotating the actuating device 21 the locking elements 25 are forced into the groove 29 (see Fig. 4 ) or be led out (by pivoting, see Figs. 5 and 6 The position according to Fig. 4 corresponds to the position according to Fig. 2 .

[0052] Furthermore, in Figs. 4 to 7 The aforementioned plate 30 is recognizable.

[0053] Tile 30 (see also) Fig. 7 ) has a slot 31 through which the sliding elements 25 (see Fig. 4The plate 30 moves with the actuating device 21 (upwards or downwards), thus enabling reliable guidance of the height adjustment. The plate 30 therefore moves within the groove 29 (when the actuating device moves upwards or downwards). According to the embodiment, the locking mechanism is formed between the locking elements 25 and the groove 29. The plate 30 has a reinforcing or stabilizing effect and improves the guidance in the groove. The plate preferably has no (or at best an insignificant) influence on the locking mechanism itself (however, this could be different in a potential alternative embodiment).

[0054] It should be noted here that all the parts described above, considered individually and in any combination, especially the details shown in the drawings, are claimed to be essential to the invention. Modifications to this are familiar to those skilled in the art.
