A CHAIR HAVING A VERTICALLY ADJUSTABLE SEAT

Description

Field of the invention

[0001] The present invention relates in a first aspect to a chair having a vertically adjustable seat and in a second aspect to the use of such a chair.

Background of the invention

[0002] In raising children, parents encounter great expenses in needing to replace clothing and other equipment used by a child. These needs to replace clothing and other equipment do not always originate from a situation in which a child in fact has worn out the clothing or equipment. On the contrary, very often these needs originate from the fact that due to the growth of a child, the child will rapidly be unable to fit such closing or equipment.

[0003] Accordingly it is economically advantageous for parents to provide equipment that can be fitted to a child irrespective of the age and thus size or height of the child.

[0004] This is not at least the case in respect of chairs intended for use when a child is eating at a dining table together with its family.

[0005] In the literature a number of chairs has been disclosed which are intended to be used by a child during dining. These chairs all share the common feature that the seat of the chair can be adjusted in height, thereby making it possible for a child to fit the chair when dining at a dining table, irrespective (within certain limits) of the age of the child.

[0006] Such a chair is disclosed in US 5.634.687 A. US 5.634.687 A discloses a child's chair, comprising a pair of spaced, parallel, vertically extending side panels having inner oppositely extending faces. The side panels comprise recesses provided in opposite sides thereof. The recesses are intended for partly accommodating opposite ends of tubes being interested into the recesses on one side of said panels. A threaded fastener assembly can be inserted through the recesses on the other side of said panels and into a plug, whereby the tubes are fastened to the side panels. A transversely extending platform can subsequently be arranged on top of the tubes thereby forming a seat for a child. By choosing various heights of the recesses accommodating the tubes, the seat height of the chair may be adjusted. However, adjustment of the seat height of this chair necessitates a more or less full disassembly and subsequently reassembly of the chair.

[0007] WO 2006/090170 A1 discloses a device for supporting a person, such as a child. The device comprises an enclosure separated into an upper part and a lower part by a moveable partition. The moveable partition is accommodated into grooves provided in two inside and opposite facing sides of the enclosure. By varying the height of the position of the moveable partition, a varying seat height of a child's high stool may be provided.

[0008] Another type of chair allowing adjustment of seat height is disclosed in DE 10 2006 040 449 A1. This document discloses a chair comprising two opposite side panel. The two side panels comprises, at corresponding heights, a number of horizontally arranged holes and cuts which allow a seat plate to be inserted into two opposing holes so as to rest in two associated cuts. This document does not disclose arranging a support plate into two opposing holes and arranging a seat plate on top of the support plate, where the support plate and the seat plate are being locked to each other via locking means.

[0009] On the marked a child's high stool is available from the company Stokke®, Norway under the trade name of Tripp Trapp®. This kind of stool comprises two opposite, vertically backward extending side panels connected to a ground plate. The two oppositely vertically backward extending side panels comprise at their inner sides a number of horizontally arranged grooves. By arranging a seat in two oppositely faced grooves at various heights, the seating height of a child may be varied.

[0010] Although the chair disclosed in WO 2006/090170 A1 and the TrippTrapp® stool provides for a change of seat height without a more or less full disassembly and subsequent reassembly of the chair, the system of change of seat heights in these chairs nevertheless implies certain disadvantages.

[0011] One of these disadvantages relies in the fact that in order to provide a chair that is safe for the child to sit in, it is of paramount importance that the seat, once positioned in the desired height, does not slide out of its associated grooves provided in the side panels. In order to achieve a safe mounting of the seat in the grooves, it is necessary to ensure that the friction between the side end of the seat and the groove is relatively high. However, such a high friction makes it necessary to exert a not insignificant amount of force when sliding the seat out of or into its associated grooves. Accordingly, changing of seat height in the chair of WO 2006/090170 A1 and in the TrippTrapp® stool is not an easy task. This will be particularly important in case the same chair is being used for different tables having different heights. In such a case it will be necessary for the parents or other persons to change the seat height every time the chair is to be used with a table, such as a dining table, having a different height compared to the height of the table used previously. In such a situation the cumbersome task of pressing the seat in and out of its associated grooves must be performed regularly.

[0012] DE 10 2008 006 460 A1 discloses a chair for children. The chair comprises a seat which is arranged between two side panels. The seat comprises to oppositely arranged protrusions arranged in the sides thereof. The protrusions are configured for being able to be inserted into oblong holes in the side panels. The seat is being locked by wedges which are squeezed into a wedge hole arranged in each protrusion. Once squeezed by the wedges, the seat is being locked by screws. In order to alter the height of the seat of DE 10 2008 006 460 A1, quite many operations have to be performed. These many operations are cumbersome and time consuming.

[0013] DE 20 2004 001 901 U1 discloses a chair for a child. The chair comprises two side panels. Each side panel comprises a number of vertically displaces cut-outs on an inner side of the side panels. These cut-outs serve the purpose of positioning a seat and a foot rest at desired heights. A seat and a foot rest may be slit into place in these cut-outs from a position in front of the chair. Once being positioned in each respective and desired cut-outs, the seat and the foot rest are being fixed with screws via through-going screw holes in the side panels. Also the chair of DE 20 2004 001 901 U1 requires quite many operations in order to alter the height of the seat of seat. These many operations are cumbersome and time consuming.

[0014] Accordingly, there is a persistent need for a chair having a vertically adjustable seat which more easily allows for change of seat height.

[0015] It is the object of the present invention to provide a chair which fulfils this need.
