Description

This invention relates to a high chair, consisting of a lower support portion and located in the upper part of the seat support approximately hemispherical.

Typical chairs of this type are intended for babies who still can not independently sit on a regular chair. This chair provides safety, as a child in it, as a rule, can be fastened. In addition, in most cases it has a table on which you can put dishes during meals, as well as, for example, toys and other items. As a rule, the seat tilt of such a chair can be adjusted relative to the supporting part in order to move the child from a sitting position to lying down and he could sleep fastened in a chair and could not fall out.

For example, US 7,905,549 B2 describes a tall chair whose tilt of an approximately hemispherical seat is as follows: the seat is held between two legs that, when viewed from the front, are approximately U-shaped, with the seat turning around a horizontal transverse axis. To adjust the tilt of the seat, on both sides in the area of the axis of rotation there are hinges with clamps, the clamps being opened by traction elements, as a result of which the hinges are unlocked, and the control element of the traction elements is located approximately in the upper part of the hemisphere of the seat. When the seat is tilted, the child is brought from approximately vertical to a recumbent position.

US 2010/0052387 A1 describes a device for laying a small child, similar to a couch; the child lies on a surface of textile material, fixed on several spacers with zippers or Velcro. At the bottom there is a complex drive mechanism designed to perform forward-backward and up-down movements according to various schemes for motion sickness. This known device also provides for the movement of one of the spacers in a circle relative to the lower part of the structure, and this spacer moves in a guide along an arc of a circle. However, this famous couch cannot be compared with a typical high chair, since a child cannot sit in it, for example, to eat, play with toys, read a book, etc. This known device is intended solely to soothe or rock a child or entertain him. Due to the complex drive, the design of this device is very expensive and expensive.

When using a hard seat with a constant hemispherical shape, such as, for example, in the aforementioned patent US 7,905,549 B2, the disadvantage of the known types of high chairs is that their useful life is limited, since only a certain size child can fit in a seat of a certain shape. After reaching a certain age, the child no longer fits on the seat, so you can use such a high chair only for infants. In the aforementioned American application on the layout drawing shows that the hemisphere of the seat, called there support for the back, is a separate part. However, it can only be removed when removing the high seat or for cleaning. After the back support has been removed, the high chair is in a disassembled condition unsuitable for use, and the use of the chair in this form without back support is not described.

The objective of this invention is to provide a variant of a high chair of the above type, which would be able to adjust in the seat area, so that after a design change a larger child could sit on it, which would extend the period of use of the chair.

The solution to this problem is a high chair of the above type with the distinctive features of paragraph 1 of the claims.

According to the invention, it is provided that the hemispherical seat consists of an outer hemisphere of a slightly larger volume and an inner hemisphere of a slightly smaller volume included therein, which can be fixed to the outer hemisphere. In this embodiment, the inner hemisphere can be removed from the outer so that a larger child can fit in it. Due to this, the period of use of the chair is extended, since the size of the seat in a certain sense is regulated depending on the size of the child.

A preferred embodiment of the invention for attaching the inner hemisphere to the outer provides for latches on one of the hemispheres that enter recesses or corresponding latches on, respectively, the other hemisphere.

To increase the volume of the seat after the recess of the inner hemisphere, it is preferable that the outer hemisphere has a greater internal width and / or greater internal height and / or greater internal depth along an axis approximately perpendicular to the internal height and / or the surface of the seat would be located at a lower height relative to the surface on which the supporting part stands, compared with the inner hemisphere.

The subject of this invention is also a new structural embodiment of the device for adjusting the inclination of the high chair. According to the invention, it is provided that at least one spacer or arc is located on the rear side of the seat, forming a part of a circle along which the seat can be moved to change the tilt, this spacer or arc moving in a guide connected to the supporting part. A regulating device of this type can be provided in a preferred embodiment of the invention and combined with a removable internal hemisphere. In particular, when the child needs to be put to bed, it is preferable to be able to bring the hemisphere of the seat to an approximately horizontal position.

Thanks to the above solution according to the invention, when adjusting the tilt, the seat performs a new movement. If in the known US 7,905,549 B2 a hemispherical seat is rotated around a predetermined axis passing through the seat, in the solution according to the invention the center of the circle is outside the contour of the seat, that is, the movement is performed over a larger turning radius, and when moving to a flatter position, the seat supporting part moves farther away from the guide device, which is a fixed point.

According to a further preferred embodiment of the invention, it is provided that the guide device can be height-adjusted with respect to the supporting part. In this case, regardless of the tilt adjustment, you can change the height of the entire seat. The height adjustment device may be, for example, telescopic. According to another preferred embodiment of the invention, it is provided that the guide device can be height-adjusted with respect to the supporting part along a line inclined with respect to the vertical. Thus, in contrast to the known constructions, the height adjustment is performed not exactly vertically, but along a linear guide deviating from the vertical, for example, by several degrees. If the seat needs to be moved to a flatter position, the center of gravity of the high chair according to the invention is shifted forward. When the height adjustment device is tilted back, when lifting, the center of gravity again shifts somewhat backward, which provides some compensation.

According to another preferred embodiment of the invention, it is provided that the telescopic device for adjusting the height is an external rack mounted on the support part and inclined relative to the vertical, from which at least one internal telescopic rod is mounted on which the guide device is mounted, or the rod mounted on the support part, relative to which the height of the outer pillar, on which the guide device is mounted, is adjustable.

According to another preferred embodiment of the invention, it is provided that the stand or the rod of the telescopic height adjustment device is mounted offset from the center of the support part, for example, in the rear region of the support part, if the seat is in front of the rod and the guide device. This is necessary to increase stability and prevent tipping over.

For the legs of the child sitting on the chair, it is preferable to provide a support that can be removed from the seat. This supporting element is an approximately U-shaped arc, and in the fixed state, the arc is partially located at a distance from the lower edge of the seat so that the child can put his feet on the support under the hemisphere of the seat.

According to a preferred embodiment of the invention, a removable holder in the form of a spacer is attached to the hemisphere of the seat at two, more preferably at three points, to which, in turn, a removable table can be attached.

Thus, in contrast to the known options, the holder is not attached to the seat itself. The table and its holder can be removed from the seat individually. If necessary, the table can be removed, in particular, if you need to remove the inner hemisphere from the seat in order to put a larger child.

Preferably, the strut or arch when viewed from a side view of the chair is part of a circle, and the guide device is a tubular fastener corresponding to a short segment of the circle, through which the strut or arc can be drawn when the seat is tilted. In the corresponding position, the bracket / arc can be fixed in the guide device.

According to a preferred embodiment of the invention, when viewed from the side of the chair, the spacer or arc covers the contour of the hemispherical seat with a possibly varying distance, and (or) the seat is fixed at least at two points located diametrically opposite when viewed from the front, at the respective ends of the spacer or arc. Thus, the seat is held at opposite ends of the arcuate strut, so that the seat travel path is adjusted to a maximum when tilting and the seat can be moved in both directions until the corresponding end reaches the guide device.

The characteristics mentioned in the subclaims relate to preferred improvements of the invention. Other advantages of the invention are given in the following detailed description.

Below the invention is described in more detail with examples of executions with reference to the accompanying drawings.

fig. 7 is a rear view of a tall chair according to the invention, in perspective.

Below is a description of fig. 1 and 2. The high chair 10 according to the invention consists of a support part 11, which is located on the floor, and a hemispherical seat 12. From the support part 11, a height-adjustable stand 13 rises, and it does not rise vertically from the support part 11, but at an angle somewhat degrees from the vertical; at the upper end of the rack there is a guide device 14. The guide device 14 is a hollow curved tube in which there is a part of the circumference of the arc 15, which can pass through the guide device. The arc 15 serves to mount the hemispherical seat 12, which, as can be seen in Fig. 2, is mounted on an arc in two places, namely at the upper and lower end. Arc 15 is part of a circle slightly less than a semicircle. Seat 12, as shown in fig. 1, has an oval shape, and on the rear side of the hemisphere in two diametrically opposite places there is an arc 15. When the seat tilt changes, the arc (or spacer) 15 passes through the guide hole 14, so that the seat can be in different positions shown in Fig. 3 and 4, in which the child can sit or lie. The extreme points of the path of movement of the arc 15 in the guide device 14 are set by the area of attachment of the arc on the hemisphere of the seat.

The supporting part 11 is designed to increase the stability of the chair. In this case, the supporting part can consist of either an external, approximately U-shaped strut 11 a, as well as an approximately V-shaped part 11 b, from which the fastening of the stand 13 protrudes upward, or, as shown in Fig. 3, from the outer ring 11 c with an approximately V-shaped portion from which the strut on which the seat is mounted rises. In this case, the rack can be more or less offset relative to the center of the supporting part 11, as shown, in particular, in Fig. 3. The stand 13 deviates slightly from the vertical toward the rear side of the seat, since the seat 12 is directed forward from the arc 15 and the guiding device 14, so that the center of gravity of the high chair is compensated and is located approximately above the center of the support portion 11.

The high chair 10 also has a removable table 16 for the child and a leg support 17 having the shape of a ring, approximately a U-shaped contour and, as shown in Fig. 1, located at a distance from the also arched lower edge of the hemisphere of the seat 12, so that the child can comfortably put his feet on this support element. Preferably, the leg support 17 can be removed from the seat, as will be described below.

The height adjustment device is offered in two versions, shown in fig. 2 and 4. In the first embodiment, according to Fig. 2, the guiding device 14 is mounted on the stand 13, and the outer stand 13 with the guiding device 14 extends upward, for example with a gas-filled spring with an internal rod (in Fig. 1 this is shown only approximately). In the second embodiment, according to Fig. 3 and 4, the outer strut 13 is rigidly fixed to the supporting part 11, and the inner rod 18 when lifting the seat 12 extends from the outer strut 13 telescopically. In this case, the guide device 14 is located on the upper end of the rod 18 and rises with it. Guide device 14 and outer post 13 in fig. 4 are divided, while in the variant in fig. 2, the guiding device 14 and the outer strut are interconnected and rise together. In fig. 3 shows the lower position of the seat 12, and in fig. 4 - a slightly raised position, with the arc 15 being passed through the guide device 14, the seat 12 is brought to a flatter position in which the child can lie.

In fig. 4 in comparison with fig. Figure 3 shows that as a result of a change in the incline of the seat due to the fact that the center of gravity of the circle around which the seat rotates is slightly higher than the seat 12, when moving from a more vertical position according to Fig. 3, the front of seat 12 is pushed forward to a more horizontal position according to fig. 4. Thus, the turning radius defined by the circle that passes through the arc 15 is relatively large, in contrast to the known options in which the turning radius is smaller, since the hinge axis passes through the center of the seat itself.

Fig. 4, in addition to the height and tilt of the seat 12 is also different in that in Fig. 4 table 16 and leg support 17 removed from the seat.

Other structural details of the seat 12 of the high chair 10 are shown in the layout drawing (Fig. 5). There is shown a table 16, removed from the seat. In addition, the inner hemisphere 21 is shown, which can be removed from the outer hemisphere 20 of the seat 12, and the volume of the inner hemisphere 20 is slightly less; the inner hemisphere can be completely inserted into the outer hemisphere to the edge 21 a, and the edge 21 a protrudes beyond the edge of the outer hemisphere 20, as shown also in Fig. 3. For fixing the inner hemisphere 21 on the outer hemisphere 20, for example, latches on one of the hemispheres are provided, which enter the recesses on, respectively, the other hemisphere. These fasteners in fig. 5 are not shown. A removable bracket 19 is mounted on the inner hemisphere 21 for mounting the removable table 16. The holder 19 may, for example, be a central vertical rod on which the table rests and an approximately U-shaped strut located horizontally and connected to a vertical rod about the center front. A horizontal U-shaped spacer is attached to the inner hemisphere 21 with its ends directed to it, and a vertical rod is attached to the seat with its lower end. Table 1 rests on a horizontal U-shaped spacer with its underside.

As also shown in fig. 5, the U-shaped leg support 17 (see also Fig. 3) can also be removed from the seat 12 of the high chair. For this, the leg support 17 can, for example, be mounted on the outer hemisphere 20 so that both bent segments are pressed against the edge of the outer hemisphere 20 in the lower part, however, there is a distance between the leg support leg 17 and the lower hemisphere edge and the support was similar U-shaped arc shown in fig. 1 so that the child can comfortably place her feet on her.

The smaller inner hemisphere 21 can be removed from the larger outer hemisphere 20 shown in Fig. 5, in order to increase the volume of the seat and in this way to turn the chair with the inner hemisphere 21, intended for infants, into a chair for older children at a relatively low cost. In fig. Figure 6 shows again a perspective view of a high chair from fig. 5 with the inner hemisphere pulled out (front view at an angle), so that in fig. 6 in comparison with fig. 1 it can be seen that there is more space in the outer hemisphere 20, since the seat surface is lower than when the inner hemisphere is installed, and that the volume of the outer hemisphere 20 is larger than the inner one, that is, the outer hemisphere 20 preferably has a larger internal width, greater internal height a large internal depth along an axis approximately perpendicular to the internal height, and (or) that the lower surface of the seat is located at a lower height relative to the surface on which the supporting part stands, compared to the internal floor sphere 21.

In fig. 7 shows a perspective rear view of a tall chair according to the invention, similar to the variant shown in fig. 1 and 2. It can be seen here that the arc 15 passing through the guiding device 14 can have, for example, a flat oval cross-section, and not necessarily round. In addition, in fig. 7 it can be seen that on the rear side of the guide device there is a locking lever 22 with a hinged support. If the locking lever 22, for example, with the eccentric for fixing, is moved up, the arc 15 in the guide device is unlocked and can move in it, while if the lever 22 is in the lower position, the arc 15 is fixed in the guide device 14 and cannot move that is, the seat is locked in the appropriate position.
