Description

The invention relates to a high chair, especially for babies and toddlers, consisting of a frame, a seat part and a backrest with adjustable inclination relative to the seat part.

Such high chairs are usually available for babies and infants from 6 months, d. H. the child must be able to sit independently. Particular embodiments provide an adjustable backrest whose inclination relative to the seat is adjustable.

However, newborns aged 0 to 6 months are dependent on a bed. For this case, additional cradles are offered, which are alternatively mountable on the frame of the highchair and thus allow use for newborns. With regard to the required production costs, however, this is not a satisfactory solution variant.

Object of the present invention is therefore to provide a high chair, which is flexible for newborns, older babies and toddlers used and yet has a simple and inexpensive construction.

This object is achieved by a high chair according to claim 1. Advantageous embodiments of the high chair are the subject of the subordinate claims to the main claim.

According to claim 1, therefore, a high chair is proposed which has a frame, a seat part and a back part. Seat part and back part can be attached both individually or both individually or directly on the frame. The back part is made adjustable, so that its inclination relative to the seat part can be varied. It is conceivable to connect the back part with the frame and / or the seat part adjustably.

To solve the problem is now inventively provided that the high chair on the back part is selectively adjustable in at least one lying position or at least one seating position. This structure results in the simplest means a particularly flexible use of the high chair. This is therefore available for newborns aged 0 to 6 months and for older babies and toddlers over the age of 6 months. Under the at least one lying position is to understand an orientation of the back part to the seat part, which allows use of the highchair as a bed for newborns. Adjusting the backrest to a sitting position ensures regular use of the highchair function for older babies and toddlers who are already able to sit independently. The high chair is preferably characterized by the fact that the angle of inclination of the back part, in particular with respect to the seat part, of about 90 ° to 180 °, particularly preferably from 100 ° to 180 ° can be adjusted.

In particular, the highchair according to the invention is a high chair or a combination high chair. In this case, the frame can be height-adjustable be executed, ie the seat height can be adjusted in the vertical direction and vote on the size of the toddler.

To adapt the seat can also be provided an adjustable attachment of the seat part on the frame and / or on the back. Preferably, the seat part is slidably mounted, particularly preferably mounted displaceably in the horizontal direction, for example via a rail or similar guide means. This offers, especially in the lying position, certain advantages, since the lying surface can be extended by the slidable mounting, d. H. is renewable. Even in the sitting position, the storage of the seat part provides a flexible adaptation of the seat to the size of the toddler.

The adjustment mechanism of the back part is basically arbitrary. Ideally, the back part is pivotally hinged to the high chair, preferably articulated pivotably on the seat part and or or on the frame. The pivot axis of the back part is oriented horizontally and expediently runs parallel to the transverse axis of the seat. Alternatively, the back can be removably attached to the seat part and / or frame, with possibilities for flexible attachment, each with a different inclination angle are provided.

The lying position is characterized by no or little inclination of the back part to the horizontal, i. an angle of inclination to the seat part of approx. 180 °. It is conceivable that at least one lying position by a nearly horizontal orientation of the back part, d. H. the back surface is characterized. Particularly preferred is the orientation of the seat part, d. H. the seat, also almost horizontal.

The adjustment of the back part can preferably be carried out stepwise or continuously in order to ensure the most flexible alignment and positioning of the back part relative to the seat part. As advantageous proves an adjustability of the back part in inclination levels between 5 ° to 20 °. Particularly advantageous adjustment stages between 8 ° and 15 ° and ideally of 10 ° are proposed.

In a particularly advantageous embodiment of the high chair, the inclination of the back part is adjustable stepwise or continuously over a pivot angle of about 80 °, in particular of about 90 °. The back part can thus be adjusted from a nearly vertical position with an inclination angle of about 90 ° to 100 ° in a nearly horizontal position with an inclination angle of about 180 °, in particular pivot.

The fixation of the back part in at least one sitting or reclining position is expediently achieved by means of at least one locking element, which enables a detachable locking of the back part on the frame or alternatively or additionally on the seat part. The locking mechanism is basically arbitrary execute as advantageous proves a latchable lock.

At least one locking element preferably comprises at least one fixed and at least one movable part. It is conceivable that at least one movable part is arranged on the back part and at least one fixed part on the frame and / or seat part. The arrangement of the movable part is preferably coaxial with the pivot axis of the back part, i. the at least one movable part rotates at a tilt adjustment of the back part about the pivot axis.

A latching of the movable part in at least one of the frame and or or on the seat part arranged fixed locking part leads to the desired locking of the back part. Conceivable is an engagement of the movable locking part in a fixed toothing.

In an advantageous embodiment, the movable locking part comprises an outer toothing, in particular an outer toothed wheel, which is arranged coaxially to the pivot axis of the back part. In addition, an internal toothing, in particular a gear with internal teeth, be provided on the fixed locking part. An engagement of the outer toothing in the inner toothing causes a latching locking of the locking element and a blockage of the rotational movement. The lock is released as soon as the inner and outer teeth are no longer engaged.

Ideally, a handle on at least one locking part is provided to solve the lock. Preferably, at least one grip protrudes from a frame side surface accessible.

The locking element is preferably held by at least one spring element in its locked position. By applying a tensile force against the tensile stress of the spring element, the lock can be solved. In particular, by removing the handle, the lock can be solved.

It may be provided to execute the seat part as a shaped wood part. Preferably, the back part is designed as a shaped wood part, wherein one or more lateral boundaries, d. H. Sidewalls can be generously mitangeformt. However, the core idea of the invention can also be applied to high chairs, which are made of any materials. Of course, the shape of a seat part or a back part is at least partially made of plastic or metal conceivable. The frame can also be made as a wooden part. Again, the choice of materials is not limited.

To secure the newborn, an older baby and a toddler, at least one occupant belt may be provided which allows the occupant to be immobilized both in the lying position and in the sitting position. Ideally, a five-point belt is used for this purpose.

The high chair can have additional elements in addition to the seat part, back part and frame. It is conceivable in this context, a removable and / or adjustable table element. In addition, one or more stair elements may be arranged on the frame, preferably in the form of two or more connecting the frame legs cross struts.

Basically, at least one seat part and at least one back part form a common unit, which can be optionally fastened to any highchair frame construction. The invention is therefore directed to a sitting and lying unit consisting of a seat and back part for a high chair according to the present invention and an advantageous embodiment of the invention. The advantages and characteristics of the sitting and lying unit obviously correspond to those of the highchair according to the invention, which is why a further explanation is omitted here.

In addition, it may be provided, in particular, that the sitting and lying unit can be exchanged with a frame. This allows a particularly flexible and application-oriented use, for example, as a stair high chair frame or alternatively on a combination high chair frame.

advantageous embodiments of the high chair according to the invention.

In the highchair 10 according to the invention Fig. 1 allows the adjustable backrest 50 in combination with the seat board 40, the use of the high chair as a couch. The backrest 50, together with the seat board 40, a sitting and lying unit that can be flexibly mounted on any frame 60. Depending on the application, a suitable frame 60 can be selected for the reception of the sitting and lying unit according to the requirements of the customer.

In detail shows Fig. 1 three juxtaposed perspective views of the highchair 10. All three high chairs 10 show a possible seating position, with the representations are characterized by different inclination angle of the backrest 50. The desired inclination of the backrest 50 is adjusted by a pivoting movement of the backrest 50 about its pivot axis AA.

The target position of the backrest 50 is fixed via two locking elements 20. For this purpose, an independent locking element 20 is provided on each side surface 61 of the frame 60, each having a vertically protruding from the side surface 61 handle 23. By pulling the handle 23 orthogonal to the side surface 61, the locking of the backrest 50 can be solved, the pivoting movement is released. Thus, an inclination angle of the backrest 50 can be set between 100 ° and 180 °.

The highchair shown thus combines two functions, d. H. a reclining function for newborns and a reclining and seating function for older babies and toddlers in a single product. There is no additional investment for additional parts, such as a cradle, necessary.

The backrest 50 can be adjusted at 10 ° intervals about the horizontal axis AA. For the sitting position different inclination levels can be selected to optimally adapt the occupied sitting position of the infant to the appropriate circumstances. In this case, the backrest 50 of a almost perpendicularly extending back surface are brought into an almost completely horizontal orientation by the backrest 50 is pivoted up to 90 ° about the pivot axis AA. By pulling out both handles 23 on the frame side surfaces 61, the lock is released and the backrest 50 can be adjusted to the desired position. When releasing the grips 23, these snap independently into the locking position and ensure a reliable fixation of the backrest position.

To expand the reclining position, the seat board 40 is mounted horizontally displaceable on the frame 60 via a rail. In addition, a likewise displaceably mounted staircase 90 may be provided. The toddler is protected from falling out over the crossbar 70. Alternatively, instead of the crossbar 70, a horizontally adjustable table 80 can be attached to the frame 60.

Based FIG. 2 the detailed structure of the locking elements 20 will be explained. The FIGS. 2a, 2b show exploded views from different perspectives. The components 21, 23, 24, 25, 26, 27, 28, 29, 30 form the movable part of the locking element 20, which is fastened to the backrest 50, and the components 22, 31, the fixed part, which is arranged on the frame 60 is.

In detail, the locking element 20 comprises a fastening part 21, which is bolted to the side cheek of the backrest 50 externally by means of the two screws 30 and the washers 25. On the surface of the fastening part 21 protrudes a sleeve 32, on the outer circumference four horizontally extending grooves 33 are recessed.

On the sleeve, the handle 23 can be attached, which, as in Fig. 2b to see corresponding ribs 34 has. The ribs 34 can be inserted in register into the grooves 33 of the sleeve 32 of the fastener 21 and allow sliding of the handle 23 on the sleeve 32 in the horizontal direction. The handle 23 also has an axial central bore through which the stem 26 is completely carried out. End of the stem 26 has a circumferential groove 35. flush to the central bore of the sleeve 32, the fastener 21 also has a borehole. The stem 26 extends through the central bore and emerges at the wellbore opening of the attachment portion 21. The stem 26 is secured by means of the lock washer 29, which is pressed into the circumferential groove 35 of the handle 26 against pulling out.

The spring element 28 is placed around the stem circumference. The diameter of the central bore of the handle 23 tapers in the direction of the fastening part 21 facing the end. The spring element 28 thus abuts in the central bore at the tapered bore end. The opposite end of the spring 28 abuts the head of the stem 26. The diameter of the handle head is smaller than the diameter of the central bore of the handle 23, so that the handle when retracting the handle 23 is completely retractable in the opening. On the handle surface 23, a cover 24 is provided, the four protruding pins can be inserted into corresponding openings of the handle 23.

The fixed part of the locking means 20 comprises a ring 22 which is fixed to the frame 60 on the back surface 50 facing side surface 61. The ring 22 has in its inner diameter an internal toothing 36, whose diameter is matched to the external toothing 37 of the handle 23 and allows the mutual engagement. In addition, the ring 22 is widened in the region of the toothing 36. This ring attachment 38 can be inserted into the corresponding bore of the frame side member 61 and provides for improved stability of the arrangement.

The basic function of the locking means 20 will be described below with reference to FIG Fig. 3a, 3b described in more detail. Both figures show a cross-sectional view of the locking means 20 along a vertical axis, the reference numerals correspond to those of FIG. 2 ,

Fig. 3a shows the locking means 20 in its locked position, whereas Fig. 3b an extracted handle 23 for releasing the locking features. How this in detail the Fig. 3b can be seen, this is the handle 23 pulled out to the right, so that both teeth 36, 37 of the handle 23 and the fixed ring 22 are no longer in mutual engagement. The pivoting movement about the pivot axis AA is released.

By the pulled out handle 23, the spring element 28 is simultaneously compressed. The built-up compressive stress causes when releasing the handle 23 of this back to the starting position according to FIG. 3a slides and both teeth 36, 37 are engaged again.

The 4 to 6 show different versions of the high chair 10 according to the invention in each case in lying and sitting position. For example, shows Fig. 4 a stairchair with the seat and reclining unit according to the invention from the backrest 50 and seat part 40. The frame 60 used has two curved side elements 62. In addition, a stair member 90 can be secured transversely between the side members 62 for the seat operation. Optionally, the table element 80 can be removably and adjustably attached to the frame 60. In particular, two boreholes per side part 61 are available for receiving the table element 80. The backrest 50 is articulated via a respective locking means 20 per side surface 61 pivotally mounted on the frame 60. To take the lying position, not only the backrest is pivoted relative to the side parts 61, but the side parts 61 themselves are rotated about 180 ° on the frame 60 mounted. The adjustment of the side parts 61 can of course be done without assembly process by means of a hinge or other suitable adjusting means.

Fig. 5 also shows a high chair 10 with alternative design of the frame 60. In contrast to the execution of Fig. 4 the frame 60 per side part 62 in each case two arranged in A-position frame legs 63. The backrest 50 is analogous to Fig. 4 via a respective locking means 20 per side surface 61 pivotally hinged to the frame 60. An offset of the side parts 61 is not necessary in this embodiment. The seat part 40 can also be in horizontal Moving direction to enlarge, if necessary, the lying surface of the reclining position shown on the left, or to adapt the sitting position of the sitting position shown on the right to the size of the child.

Last shows Fig. 6 an embodiment of the high chair according to the invention as a combination high chair. The design is similar in many parts to the highchair Fig. 5 , This variant is also designed to be height adjustable, so that individual frame parts are mounted displaceably in the vertical direction.

By the illustrated invention, it is now possible with a product to accompany the different stages of development from birth to childhood, d. H. The period before the child is sitting independently is now covered. For the parents, this provides a more versatile use than currently available on other models available on the market.
