Description

Chair
The present invention relates to a chair, in particular an office chair.
Known office chairs are typically designed for achieving proper ergonomics and ensuring user comfort. Thereto, contemporary office chairs are equipped with adjustability solutions such as seat height adjustment, backrest height and angle adjustment, armrest height and width adjustment, seat depth adjustment, tilt mechanisms, lumbar support adjustment, et cetera. While these measures can be beneficial for ergonomics and user comfort, the moveability of the different chair components needed to provide the adjustment options to obtain the desired ergonomics and comfort is typically at the expense of the
IO stability of the chair as a whole. This stability is however important for chairs which are used intensively, such as chairs used by computer game players. Such players often sit in their seat for a prolonged period of time and, in the heat of the game, often move around intensively, whereby the chair and particularly some of its components are relatively heavily loaded.
The invention has for its object to improve a chair of the above described type, such that it is better suited to intensive use, such as while playing computer games, while not compromising the adjustability thereof.
According to the invention, this is achieved by a chair, comprising a frame for a seat part of the chair, the frame comprising at each of two lateral sides thereof a substantially upright frame part for connecting an armrest thereto. Each upright frame part comprises two elongate upright frame members arranged parallel and adjacent to each other. Each armrest comprises two substantially downwardly extending elongate shafts arranged parallel and adjacent to each other. The two upright frame members and the two shafts are configured such that each of the two shafts is connectable over at least part of its length to a different one of the two upright frame members so as to connect each armrest to its respective upright frame part.
A beneficial technical effect of this configuration comprising two parallel and adjacent upright frame members to which two shafts of each armrest can be connected is that a very stable armrest, since this configuration prevents any rotational movement about an axis substantially parallel to the substantially vertically extending longitudinal axes of the upright frame members and shafts as well as about an horizontal axis extending in a lateral direction from the chair and perpendicular to said substantially vertically extending longitudinal axes.
In preferred embodiment of the invention, the two upright frame members and the two shafts are correspondingly shaped such that each of the two shafts is insertable over at least part of its length in a different one of the two upright frame members, so as to connect each armrest to its respective upright frame part. Alternatively, each of the two upright frame members is insertable over at least part of its length in a different one of the two shafts, so as to connect each armrest to its respective upright frame part. Connection of the shafts to the upright frame members by mutual insertion ensures a very solid connection.
Preferably, outer ones of the two upright frame members and the two shafts are directly structurally connected to each other by means of a connection member sandwiched between said outer ones of the two upright frame members and the two shafts. The connection member provides additional rigidity to each pair of upright frame members and shafts, thereby benefiting the stability of the armrest.
In a preferred embodiment, the two upright frame members and the two shafts are configured such that the two shafts are moveable relative to the two upright frame members along a their longitudinal
IO axes so as to adjust to height position of the armrest.
In a preferred embodiment, the frame comprises a rear portion and a front portion. The rear portion is substantially U-shaped and comprises a laterally extending rear frame part extending across the width of the frame and, at each of two opposing ends of the laterally extending frame part, one of the two upright frame members, each being formed integrally with the laterally extending frame part. The front portion comprises parallel to the laterally extending rear frame part a laterally extending front frame part extending across the width of the frame and two substantially parallel rearwardly extending opposing side frame members elevated from the front frame part by intermediate vertically extending frame members between each of opposing ends of the front frame part and each side frame member. The two side frame members extend toward the rear portion across the length of the frame, wherein at each end of the two side frame members facing the rear portion, the other one of the two upright frame members is formed integrally with its respective side frame member and extends in a substantially downward direction. The integral connection of the upright frame members with the horizontal parts of the frame ensures that forces exerted on the armrests are transmitted to the seat frame, in particular to the horizontally extending parts of the frame. In particular, the intermediate vertically extending frame members and the side frame members formed integral therewith cooperate together to further prevent any rotational movement about an horizontal axis extending laterally from the chair and perpendicular to the substantially vertically extending longitudinal axes of the upright frame members and shafts. In other words, the configuration according to this preferred embodiment provides a very rigid basis for the armrests of the chair. The chair according to the present invention is thus very well suited for intensive use. The armrest construction provided by the upright frame members and shafts even allowed to connect the armrests to a desk behind which the chair is used, thereby providing even greater stability to the chair.
In a preferred embodiment, a length of the intermediate frame members corresponds substantially to a length of the upright frame members of the rear portion, so that upper ends of the upright frame members of the rear portion are substantially flush with upper ends of the substantially downwardly extending upright frame members of the front portion.
In a preferred embodiment, the chair further comprises for each armrest a height adjustment device for adjusting and fixing the height position of the armrest. The height adjustment device is configured to engage at least one of the two downwardly extending shafts of the armrest and to fix the height position of the armrest. While the chair according to the present invention is configured for intensive use, the height adjustment device still allows great flexibility as to the height of the armrest.
Preferably, said at least one of the two downwardly extending shafts is provided with a series of notches arranged one above the other and wherein the height adjustment device comprises a protrusion
IO member to be received in one of the notches of the series of notches. Such notches provide easy adjustment of the armrest.
In a preferred embodiment, the protrusion member is spring loaded, such that in a rest position of the protrusion member, the protrusion member can protrude in one of the notches of the series of notches.
In this way, the armrest does not slide down due to gravitational forces, as the spring of the spring-loaded protrusion member ensures that the protrusion member is always arranged in one of the notches.
Preferably, the height adjustment device comprises a clamp device configured to clamp at least one of the two shafts of the arm rest onto its respective upright frame part. The claimed device ensures that the armrest does not slide down when additional forces are exerted on top of the armrest, so that the armrest can be intensively used.
In a further preferred embodiment, the clamp device comprises a clamping member configured to engage the at least one of the two shafts and a tensioning bolt to clamp said at least one of the two shafts between the clamping member and its respective upright frame part.
Preferably, the tensioning bolt is a quick release tensioning bolt. The quick release tensioning bolt allows for quick and easy switching between a release state, in which the height position of the armrest can be adjusted, and a clamping state, in which the height position of the armrest is fixed, such that height position adjustment and fixation is quick and easy.
In a preferred embodiment, the two upright frame members and the two shafts are correspondingly shaped such that each of the two shafts is insertable over at least part of its length in a different one of the two upright frame members. The height adjustment device is configured to embed therein a length portion of each of the two upright frame members and a portion of the side frame member at the end of which one of the two upright frame members is formed integrally. A technical benefit of such a height adjustment device, wherein portions of the two upright frame members and the side frame member which is formed integral with one of the two upright frame members are embedded, is that it provides additional rigidity to the upright frame members and thereby to the armrest. In particular, it further prevents rotational movement of the armrest about the horizontal axis extending laterally from the chair, i.e, Extending perpendicular to the upright frame members.
In one or more preferred embodiments, each of the two upright frame members comprise a recessed portion through which the protrusion member can protrude in one of the notches provided in said atleast one of the two shafts and through which the clamping member can engage said at least one of the two shafts, preferably both shafts, for clamping clamp said at least one of the two shafts between the clamping member and its respective upright frame part.
Additional features and advantages will be set forth in the detailed description which follows, and
IO mn part will be readily apparent to those skilled in the art from the description or recognized by practicing the embodiments as described in the written description and claims hereof, as well as the appended drawings.
It is to be understood that both the foregoing general description and the following detailed description are merely exemplary and are intended to provide an overview or framework to understand the nature and character of the claims.
The accompanying drawings are included to provide a further understanding and are incorporated in and constitute a part of this specification, wherein: - figure 1 shows a perspective view of a preferred embodiment of a chair according to the present invention; - figure 2 shows a side view of the chair as shown in figure 1; - figure 3 shows a detailed view of the armrest of the chair as shown in figures 1 and 2; - figure 4 shows a frame for a seat part of a preferred moment of the chair according to the present invention, including armrests installed in parts of said frame; - figure 5 shows an exploded view of the frame and armrests shown in figure 4; - figure 6 shows a top view of a cross-section along the dashed line shown in figure 4 of a height adjustment device of a chair according to a preferred embodiment of the present invention; - figure 7 shows an exploded view of the height adjustment device of figure 6.
In figure 1, a perspective view is shown of an office chair or office seat 1. The office chair 1 comprises a scat frame 2 and a backrest frame 3. The seat frame 2 1s supported by a support 4, in the shown embodiment a mobile support, comprising a central leg 5 and five feet 6 extending in radial direction.
In the shown embodiment, chair 1 is intended for players of computer games, particularly racing games, and therefore takes the form of a car seat with a characteristic bucket form. Upright frame parts 7 of the seat frame 2 at opposing lateral sides thereof and wings 8 of the backrest frame 3 protrude relatively far for this purpose. Central leg 5 of support 4 is provided in conventional manner with seat 5 height adjustment means and for this purpose takes a partially telescopic form. In the shown embodiment central leg 5 comprises a base part 9 and a narrowed part 10 which are mutually slidable in and out of each other by means of a gas spring, mechanical spring, or hydraulic system in order to vary the height of seat frame 2 above the ground. The height adjustment is operated by means of a handle (not shown) under the seat frame 2. The feet 6 are connected to the base part 9 of the central leg 5. To each of the feet 6a
IQ wheel 11 is mounted. The wheels 11 ensure that the chair 1 is mobile.
The seat frame 2 comprises at each of two lateral sides thereof a substantially upright frame part 12 for connecting an armrest 13 thereto. Each upright frame part 12 comprises two elongate upright frame members 14 arranged parallel and adjacent to each other. Each armrest 13 comprises two substantially downwardly extending elongate shafts 15 arranged parallel and adjacent to each other. The two upright frame members 14 and the two shafts 15 are configured such that each of the two shafts 15 is connectable over at least part of its length to a different one of the two upright frame members 14 so as to connect each armrest 13 to its respective upright frame part 12. A very stable armrest 13 is obtained due to the parallelly and adjacently arranged upright frame members 14 of each pair of frame members 14 at each lateral side of the chair 1, since any rotational movement prevented about an axis 16 substantially parallel to the substantially vertically extending longitudinal axes of the upright frame members and shafts as well as about an horizontal axis 17 extending in a lateral direction from the chair and perpendicular to said substantially vertically extending longitudinal axes.
Each of the shafts 15 is insertable over at least part of its length in each the upright frame members 14. A plate member 18 is sandwiched between the upright frame members 14 of each pair so as to mutually connect the upright frame members 14, thereby improving rigidity of the armrests 13.
In particular, the seat frame 2 comprises a rear portion 19 and a front portion 20. The rear portion 19 is substantially U-shaped and comprises a laterally extending rear frame part 21 extending across the width of the seat frame 2 and, at each of two opposing ends 22 of the laterally extending frame part 21, one of the two upright frame members 14, each being formed integrally with the laterally extending frame part 21. The front portion 20 comprises parallel to the laterally extending rear frame part 21 a laterally extending front frame part 23 extending across the width of the seat frame 2 and two substantially parallel rearwardly extending opposing side frame members 24 elevated from the front frame part 23 by intermediate vertically extending frame members 25 between each of opposing ends 26 of the front frame part 23 and each side frame member 24. The two side frame members 24 extend toward the rear portion
19 across the length of the seat frame 2. wherein at each end of the two side frame members 24 facing the rear portion 19, the other one of the two upright frame members 14 is formed integrally with its respective side frame member 24 and extends in a substantially downward direction. The integral connection of the upright frame members 14 with the horizontal parts, e.g. the side frame members 24, of the seat frame 2 ensures that forces exerted on the armrests 13 are transmitted to the seat frame 2, in particular to the horizontally extending parts of the seat frame 2. In particular, the intermediate vertically extending frame members 25 and the side frame members 24 formed integral therewith cooperate together to further prevent any rotational movement about the horizontal axis 17 extending laterally from the chair and perpendicular to the substantially vertically extending longitudinal axes of the upright frame members 14
IO and shafts 15. In other words, the configuration according to this preferred embodiment provides a very rigid basis for the armrests 13 of the chair 1. The chair 1 according to the present invention is thus very well suited for intensive use. The armrest construction provided by the upright frame members 14 and shafts 15 allows in particular to connect the armrests 13 to a desk behind which the chair 1 is used, thereby providing even greater stability to the chair 1.
The shafts 15 are moveable relative to the upright frame members 14 along a their longitudinal axes so as to adjust to height position of the armrest 13 and the height position can be fixed by a height adjustment device 27. The height adjustment device 27 comprises a housing 41 configured to embed therein a length portion of each of the two upright frame members 14 and a portion of the side frame member 24 at the end of which one of the two upright frame members 14 is formed integrally. A technical benefit of such a height adjustment device 27, wherein portions of the two upright frame members 14 and the side frame member 24 which is formed integral with one of the two upright frame members 14 are embedded, 1s that it provides additional rigidity to the upright frame members 14 and thereby to the armrest 13. In particular, it further prevents rotational movement of the armrest 13 about the horizontal axis 17 extending laterally from the chair, i.e. extending perpendicular to the longitudinal axes of the upright frame members 14.
Each of the two upright frame members 14 comprise recessed portions 28 through which a protrusion member 29 loaded by a spring (not shown) can protrude in one of a series of notches 31 provided in at least one of the two shafts 15 of a pair of shafts 15 and through which a clamping member 32 can engage both shafts 15, for clamping the shafts 15 between the clamping member 15 and their respective upright frame parts 14. Clamping by the clamping member 32 is realized by a tensioning bolt 33 having a quick release handle 34, which can be opened and closed to respectively release and clamp the clamping member 32.
The drawings are illustrative of selected aspects of the present disclosure, and together with the description serve to explain principles and operation of methods, products, and systems embraced by the present disclosure.
It will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit or scope of the invention. Since modifications combinations, sub- combinations and variations of the disclosed embodiments incorporating the spirit and substance of the invention may occur to persons skilled in the art, the invention should be construed to include everything within the scope of the appended claims and their equivalents.
