Description

Seating furniture, in particular high chair for children

description

The invention relates to a chair, in particular a high chair for children according to claim 1.

High chairs for children (high chairs) have been known for a long time and in various configurations. Typically, such high chairs include a frame having a pair of front chair legs and a pair of rear chair legs (or, alternatively, for example, only two chair legs that are correspondingly flared at their lower end to provide a stable footing

ensure) and a seat with a seat and a backrest.

As additional elements, armrests, a footrest, a tray, and the like may be provided The frame (with or without a seat) may optionally be foldable to allow for a use position and a (more compact) collapsed position.

The seat may be in a fixed position relative to the frame or adjustable in height, either adapting the entire seat or individual components such as the seat and / or the backrest and / or the footrest (which may then be adjusted independently of each other) can be). In the prior art, it is still common that (in height-adjustable high chairs) a certain number of predetermined positions (height positions) is made possible for the adjustable components, for example by forming holes at appropriate locations of the frame and (retractable) pins on the component to be adjusted.

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 baby chair) are provided for height adjustment, in a guideway

different, discrete, positions can take, so that the high chair is adjustable in height. In principle, similar solutions are out

US 5,238,292 A and US 4,722,570 A known. In US 5,238,292 A are

Lock elements provided which can be brought into engagement with corresponding ribs, so that also the height can be adjusted.

US 4,722,570 A describes hook elements with locking elements

can work together, also a discrete height adjustment

to be able to make. Overall, these solutions are perceived in the prior art as relatively complex in construction and handling and in particular as relatively less flexible.

It is therefore an object of the invention, a chair, especially high chair, preferably high chair for children (high chair) with an adjustable

Supporting device for supporting a body part of a child to propose, which should be possible in a simple and flexible way in particular, an adjustment of the height.

This object is achieved by a chair, in particular high chair according to claim 1.

In particular, the object is achieved by a chair, in particular a high chair, preferably a high chair for children with a height-adjustable supporting device for supporting a body part and / or an external object, such as a chair. a drinking bottle or a toy, the child's release, with the

Height adjustment device comprises a locking device, the locking of a set height, at least partially, in particular predominantly, by a frictional connection (in particular by a press fit and / or a

Deadlock). According to a further optionally independent aspect (however, which can be combined in particular with the above aspect relating to the frictional connection), the above object is achieved, in particular, by a seat, in particular a child's chair,

preferably high chair for children with a height-adjustable support means for supporting a body part of the child solved, comprising a

Height adjustment device for infinite height adjustment of

Support device is configured.

A core idea of the invention is a certain height (a height-adjustable support means) at least partially (in particular

predominantly) by a frictional connection (or friction) to lock. In a traction, there is a normal force of surfaces to be locked against each other. Overcoming the lock is only possible if an applied force exceeds the counter-force caused by the static friction. As a delimitation to the adhesion, at least two parts to be connected engage in a positive connection. As a result, the parts to be joined can not separate from each other even during or without interrupted power transmission during positive engagement. In other words, in a positive connection, the one part to be connected to the other in the way. At operating load, compressive forces act normally, i. perpendicular to the surfaces of the parts to be joined. Such form-fit connections are described, for example, in US Pat. No. 4,722,570 A,

No. 5,238,292 A and DE 690 09 806 T2.

It is not absolutely necessary that the intended frictional connection alone be able to maintain the lock (which is, however, preferably so provided). In any case, however, the locking device is configured such that a lock can only be maintained (under load) if the frictional connection also works. In other words, a detent is maintained only if the frictional connection acts or not maintained, if the frictional connection at least mentally removed (or the holding force of adhesion, at least mentally disregarded). This should apply at least to a state of the respective support device in which the weight of the support device acts. Insofar as the support device is or includes a seat (and / or a footrest), an additional load of preferably at least 5 kg, more preferably at least 10 kg (as the weight of the child) can be taken into account here. An upper limit for the weight to be added (simulating the child) on the support may be <60 kg, preferably <40 kg. For example, in a range of 5 kg to 60 kg, a lock should at least be caused by the frictional connection (in the sense that without the frictional connection at least in sections of this range, the detent would not hold). Preferably, a force that can be compensated by the adhesion (in the locked state)> 50 Newton, more preferably> 200 Newton, even more preferably> 300 Newton. Predominantly, the locking should be effected by the frictional connection, in particular when at least 50%, preferably at least 80% of a holding force (in particular under the above circumstances, for example regarding an additional weight by a child sitting in the chair) are applied. Completely the locking is effected in particular by the adhesion, if the entire force can be compensated by the frictional connection (or by the adhesion of the lock can be maintained).

The height adjusting device is preferably configured such that a setting within a height difference (in the vertical direction) of

at least 5 cm, preferably at least 10 cm, more preferably at least 15 cm is possible. Stepless is this height adjustment

Preferably, if within this height difference any height values can be set (or at least height values, which have a distance of <2 mm, in particular <0.5 mm to each other). In principle, a first Höheneinsteilbereich be provided in which the height is infinitely adjustable and a second Höheneinsteilbereich in which only a discrete height adjustment is possible. In one embodiment, however, a stepless height adjustment over the entire Höheneinsteilbereich (the respective support means) may be possible. If, in addition to an infinitely adjustable height range, there is also an only discreetly adjustable height range, a 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, even more preferably at least 10 cm.

In the embodiment, the locking device may be configured such that it causes the locking of the set height, at least partially, in particular predominantly, by a press fit and / or a jamming. Under In particular, a press fit is understood to mean a configuration in which a force (for example by a spring) is directed in the direction of one or more

Adhesive surfaces acts, so that the adhering surfaces are pressed against each other. For example, here a projection or pin (or the like) are pressed into a corresponding recess. Under a deadlock (or a corresponding clamping device) is in particular a device to understand that acts such that an increase in the loading force (for example, when a child on the seating, especially the highchair increases), an increase in force due to adhesion (friction ) causes (comparable to a wedged under a door gap wedge). By such measures a safe application is possible in a simple manner.

The support means may include a seat and / or a backrest and / or a footrest and / or an armrest and / or a Absteilfläche (for

Drinking cups and the like).

The locking device may comprise (at least) one locking groove and at least one locking element which can be brought out of the locking groove and which can be led out of the locking groove. The locking element is preferably secured in the locked state within the locking groove by a press fit and / or jamming. With such a configuration, a stepless adjustment of the lock can be made possible in a simple manner. The locking groove can be arranged on a main body (eg frame) of the seat, in particular a high chair, and the (at least one) locking element on the support, or vice versa. The interchangeability of the arrangement of each other

Frictionally connectable components also applies in principle to other possible embodiments of the invention (as described, for example, below).

A lock can be produced or released preferably by rotation of one / of the locking element and / or by a translational movement of the / a locking element. For example, the locking element can be rotated into the locking groove in order to effect a locking. As a result, a lock can be made possible in a simple manner. Preferably, the actuating element is biased, in particular in the direction of a locking position (or in a direction in which the actuating element is urged by a biasing force into the locking position). This will be the

Handling further simplified.

In one embodiment, a lock by rotation of a

Actuating element and / or produced by a translatory movement of an actuating element and / or solvable. Under a

Actuating element is in particular a handling device (eg.

comprising a handle) accessible from outside so that a user can grasp it (for releasing the lock). Such a handling device can be arranged for example in a central region of the seat, in particular high chair. Optionally, via one and the same actuating element (or

Handling device) at least two or more locking devices are actuated (so that a lock is released or produced).

Actuating element and locking element can via a (possibly translational or purely translationally movable) connecting device with each other in

Active compound stand.

In a specific embodiment, the actuating element is rotatable and arranged such that it has a (translationally movable)

Connecting device drives, which in turn one (or more)

Bar elements for producing or releasing the lock rotates. With such a configuration can be easily solved or

Making the lock be enabled.

In a preferred embodiment, a biasing, in particular

Spring device provided, which preferably acts in the direction of a locked state. Alternatively, a spring device (possibly a further spring device) may be provided which are in the direction of a non-locked

Condition works. If a biasing, in particular spring device,

is provided, which acts in the direction of a locked state, can be made in a simple (and safe) way, a lock and

be maintained. In particular, such biasing, in particular spring device, a predefined force that does not depend on the particular situation of use (eg weight of the child).

Preferably, the height adjustment is forcibly guided. This will be the

Handling simplified. Such a positive guide may include, for example, a rail and / or groove and / or backdrop.

In a specific embodiment, a guide groove for guiding a height adjustment is provided. The guide groove is preferably at least partially formed 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 unlocked state in the guide or locking groove.

Alternatively or additionally, a (further) sliding element may be provided which (for guiding or controlling the height adjustment) in the guide or

Sliding locking groove can. The sliding element is provided in particular in addition to the locking element. The sliding element can be described as (possibly concave,

in particular cylinder jacket portion-shaped platelets be formed (ie as sliding plate), which can be moved accordingly in the groove.

In particular, in the locking position (possibly also in the non-locked position), the locking element preferably penetrates the sliding element (in particular an opening in the same, which may be formed, for example, slit-shaped). Overall, this simplifies handling.

If, in general, a locking element which can be led out of the locking groove into the locking groove is provided, this does not necessarily mean that the locking element has to be able to be brought completely out of the locking groove (which, however, can possibly be), but it suffices in this sense when the locking element is at least partially herausführbar from the locking groove

(Especially in the sense that a distal end of the locking element is further removed from a groove bottom).

By a combined guide and locking a simple adjustment and locking can be achieved in a structurally simple design. The locking device can be arranged and configured in such a way that the force of gravity (of the support device itself and possibly of a child arranged on the support device) at least supports the locking. For example, gravity may be directed (redirected) to cause an increase in the normal force of stiction surfaces.

In one embodiment, the locking device has two locking elements (preferably rotatable in opposite directions). The two

If necessary, locking elements can engage in the same recess (eg groove). The two rotatable locking elements are preferably so positively guided (for example, by a common contact surface at the proximal ends of the locking elements) that they can only be rotated together. Preferably, the two locking elements store on a common axis.

In general, one or more locking elements can be mounted on the axis of rotation which is stationary relative to a main body (eg frame) of the seat, in particular a high chair. If two (especially in

rotatable) opposite locking elements are provided, may be provided in particular that a first locking element allows a locking against downward movement (at least predominantly) and a second locking element allows a locking against upward movement (at least predominantly). Furthermore, it may be that by the rotation of the locking elements (for example, by a mutually-rotating the locking elements), a further force (eg., Due to a spread) is made possible, which further improves the lock.

The one or more locking elements may be in a cross section

(In particular radial section) be wedge-shaped or possibly plan.

For each support means may be provided a plurality of locking means, preferably two, in particular one on each side of the chair, in particular high chair. As a result, a reliable locking can be made possible.

In a preferred embodiment, the height adjustment and / or the locking of the set height and / or the cancellation of the lock is / are the adjusted height with one hand. Preferably, both the height adjustment and the locking of the set height as well as the cancellation of the locking of the set height by gripping and operating a (single) handle done. For example, the height adjustment can be done by raising or lowering (or lowering) of the handle (ie generally, if necessary, by a translational movement) and the locking of the set height or the cancellation of the locking of the set height by a rotation of the handle. The handle as such is preferably formed in one piece or monolithic. Furthermore, the handle can be arranged centrally. Furthermore, the handle may have a concave outer surface (for gripping). A size (length) of the handle may be at least 5 cm, preferably at least 10 cm and / or at most 30 cm, preferably at most 20 cm. Overall, the handling of the child seat is significantly simplified.

At least one or more locking elements are preferably rotated (at least in the locked state, possibly in all possible states) downwards. This means that a load, which acts, for example, on the axis about which the respective locking element is pivotable, to a further extension

(Tilt upwards) of the locking element leads, so that the locking element basically pivots further outwards and thus an adhesive force (friction force) is increased. This can be used in a simple manner, the action of a ballast to increase the locking force.

According to the invention, a chair, in particular a high chair is proposed which has a height-adjustable component, wherein a locking (fixing) of the height adjustment can preferably be effected by a clamping device (clamping element). The (in particular wedge-like) clamping device can be attached to a main body of the seat, in particular high chair (eg.

Frame) and be designed to be engaged with the height-adjustable component - or vice versa. Thereby, the lock (clamping device) can be brought into a locking position, in which a relative movement between the main body of the chair, especially high chair and height-adjustable component is prevented, or in a dissolved state, where such relative movement is possible. On

Transition between the locked state and the released state preferably by rotation, but can also be translational. Preferably, a clamping device or a locking element is biased in the direction of locking state, for example by a spring or other (suitable biasing device).

In a preferred embodiment of the invention, a relative movement between the main body of the chair, in particular high chair and

guided vertically adjustable component, so that the relative movement follows a predetermined trajectory (or must follow). On this trajectory, continuous (stepless) positioning may be possible. As a guide means may be provided on the element (either main body or height-adjustable component), a groove, which is not the spring element (or the

Clamping device). In the locked state, the locking element (or the clamping device) can be brought into engagement with an inner surface of the groove. Preferably, in the dissolved state, the locking element (or the

Clamping device) can be moved in the groove without being blocked.

In a preferred embodiment of the invention, preferably, a transition of the locking element (or the clamping device) from a released state to a locked state by rotation take place. The rotation preferably takes place (or in such a sense of rotation) that a force in the direction of gravity (or along a guide device, such as a guide groove) the engagement (the lock) at least partially (if necessary).

completely). Alternatively or additionally, if appropriate, two locking elements (clamping devices) may be provided which may be rotatable in different directions, so that for each force (with a component in one direction of a possible movement) at least one of the locking elements (or.

Clamping devices) causes a lock.

In general, it is possible that the seating, in particular the high chair or the height-adjustable component with two or more locking elements (clamping devices or locking devices) or corresponding pairs of locking elements (or clamping devices) is provided, which solved by a common mechanism and / or can be transferred to the locked state. Further embodiments of the invention will become apparent from the dependent claims.

The seating, in particular the high chair, can be a frame, possibly with a pair of front chair legs and a pair of rear chair legs (or alternatively, for example, only three or only two chair legs, which may be extended accordingly at its lower end to a stable state to

ensure) and a seat with a seat and optionally one

Backrest. As additional elements, armrests, a footrest and / or a tray may be provided The frame (with or without a seat) may optionally be foldable to a use position and a

(more compact) folded position to allow.

The invention not only includes a height adjustment (although the

present invention is particularly advantageous for a height adjustment, since it is particularly important here that the child or other

Objects can be positioned as accurately as possible), but also generally a setting of another position of the support means, in particular a depth adjustment (i.e., in particular an adjustment of the support means further forward or further to the rear). In this respect, in the above and following, everywhere "height adjustment" can be replaced by "height and / or depth adjustment", where it does not depend on (or at least not crucially on) an orientation of the respective setting possibility (as is the case, for example, when utilizing gravity) , Furthermore, information such as "up" or "down" can then be replaced by "forward" or "downward".

Overall, in contrast to the prior art not only discrete (predetermined) positions of the height adjustment can be achieved, but a stepless adjustment can be performed. As a result, costs for material as well as production can be reduced, since not necessarily (as in the prior art) separate elements, such as recesses or the like, must be present for the individual predetermined positions. Overall, a height adjustment device is made possible, which allows a stepless height adjustment of an adjustable component and a specific Setting position can also keep safe, while the production costs are relatively low.

The invention will be described with reference to an embodiment which is explained in more detail with reference to the figures. Hereby show:

Fig. 1 is a schematic front view of a high chair according to the invention with partially transparent surfaces shown;

Fig. 2 individual elements of the high chair of FIG. 1;

FIG. 6 shows the elements according to FIGS. 4 and 5 in the position according to FIG. 5 and an oblique view; and

In the following description, the same reference numerals are used for identical and equivalent parts.

Fig. 1 shows a high chair 10 with legs 11, a seat 12, a

Backrest 13, a footrest 14 and a tray 15.

The seat 12 and the footrest 14 are (independently of each other) adjustable in height with respect to the legs 11. The mechanism for

Height adjustment is analogous to the seat 12 and the footrest 14, so that in the following only the mechanism for height adjustment of the seat 12 is explained in detail. The seat surface 12 generally comprises a (symmetrical) locking device 20. The locking device 20 has an actuating device (lever) 21 and a stabilizing strut or a housing 27. On each side of the

Arretiereinrichtung are further a power transmission device (rod) 23, a spring 24, a contact element 28 (at the end of the power transmission device 23), which may be formed as a pressure plate, and two locking elements 25 and clamping devices 25 (see FIGS. 2 and 3).

The spring biases the locking elements 25 against each other in a locked state, these locking elements 25 are brought to a (associated) leg 11 of the high chair 10, specifically with a groove 29 provided there, in engagement. When the locking device 20 is in a locked state, the actuating device 21 (at least substantially) may be formed in parallel with the housing 27 and possibly a flush surface therewith

Form housing.

The actuator 21 has a (round) central portion 22 and (in the present case two) recesses 22a, wherein in the locked state, each recess 22a is in engagement with one of the power transmission means 23 (rods). The locking elements 25 (on each side) are pivotally mounted on the housing 27 about a common axis 26.

The locking device can be transferred from a locked state to a released state by the actuator 21 is rotated, so that the power transmission device 23 is moved to the outside (since the power transmission device 23 then no longer engaged with the

Recesses 22a can stay). Thereby also the abutment means (pressure plate) 28, which at a distal end of the respective

Power transmission device 23 is arranged, moves outwardly and presses against proximal ends of the locking elements 25. Due to this movement, the locking elements 25 pivot about their (common) axis 26 against the biasing force of the spring 24 and thus detach from the leg eleventh

By a rotation of the actuator 21 (back to its original position), the spring 24, the locking elements 25 zurückverschwenken so that they are in turn locked with the leg 11, since in this state Power transmission device 23 in turn is in engagement with the recesses 22a. As a result, in the case of an upward force or downward force, one of the locking elements (clamping means) 25 can come into clamping engagement with the corresponding groove 29 and thus prevent the seat 12 from being moved in the direction of force.

4 shows a side view of individual elements of a highchair according to the invention. This can be formed according to FIGS. 1 to 3, so that Fig. 4 can also be regarded as illustrating further details of the high chair according to FIGS. 1 to 3. In FIGS. 1 to 3, however, the sliding plate 30 is not shown. This sliding plate 30 may optionally be provided in the embodiment according to FIGS. 1 to 3 (or not). Conversely, although the sliding plate 30 is shown in FIGS. 4 to 7. In particular, however, this sliding plate is only optional in the embodiment according to FIGS. 4 to 7.

4 to 6 it can be seen that by rotation of the actuating device 21, the locking elements 25 are forced into the groove 29 (see FIG. 4) or led out (by pivoting, see FIGS. 5 and 6). The position according to FIG. 4 corresponds to the position according to FIG. 2.

Furthermore, in Fig. 4 to 7, the already mentioned platelets 30 can be seen.

The plate 30 (see also Fig. 7) has a slot 31 through which the sliding elements 25 (see Fig. 4) can penetrate. The plate 30 moves with a movement of the actuator 21 (up or down), so that a reliable guidance of the height adjustment is made possible by the plate 30. The plate 30 thus moves in the groove 29 (with movement of the actuator up or down) with. According to the embodiment, the locking (locking) between the locking elements 25 and the groove 29 is made. The plate 30 has in particular reinforcing or stabilizing effect and improves the guidance in the groove. On the lock

As such, the platelet preferably has no (or at best negligible) influence (in a potential alternative

However, this can also be different).

It should be noted at this point that all parts described above, taken alone and in any combination, especially in the Drawings shown details are claimed as essential to the invention. Variations thereof are familiar to the person skilled in the art.
