Seat and method of assembling a support thereof

Abstract

A seat includes a seat surface and a central leg with feet close to an end remote from the seat surface. The feet are movable between a transport position substantially parallel to the leg and an operative position extending substantially radially from the leg. Several feet are connected to each other by at least one connecting element extending from the leg. A method includes supplying a central leg with feet in a transport position directed substantially parallel to the leg, supplying at least one connecting element, moving the feet from the transport position to an operative position extending substantially in radial direction from the leg, and connecting at least several feet to each other using the connecting element, wherein the connecting element extends at a distance from the central leg.

(11) FIG. 10 is a flow diagram showing the most important steps of the method according to the invention.

(12) A seat 1 comprises a seat surface 2, a backrest 3 and a pair of armrests 4 (FIG. 1). Seat surface 2 is supported by a support 5, in the shown embodiment a mobile support, comprising a central leg 6 and five feet 7 extending in radial direction.

(13) In the shown embodiment seat 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. Wings 8, 9 of seat surface 2 and backrest 3 protrude relatively far for this purpose, while backrest 3 is in addition provided with an integrated headrest 10 and openings 11, which in a car seat serve to guide the seatbelts through.

(14) Central leg 6 of support 5 is provided in conventional manner with a height adjustment and for this purpose takes a partially telescopic form. In the shown embodiment central leg 6 comprises a base part 6D and a narrowed part 6E (FIG. 5), on which are arranged three parts 6A-6C which are slidable relative to each other. These three telescopic parts 6A-6C 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 surface 2 above the ground. The height adjustment is operated by means of a handle 12 under seat surface 2. Seat surface 2, backrest 3 and armrests 4 also have various other adjustment options. The firmness of seat surface 2 can thus be adjusted by means of a rotary knob 22, while a second handle 23 is provided for adjusting a tilt angle of seat surface 2 and backrest 3.

(15) In the shown embodiment feet 7 are connected pivotally to base part 6D of central leg 6. They are hereby movable between a collapsed transport position, in which they are directed parallel to the central leg 6 (FIG. 6), and an operative position in which they protrude in radial direction from leg 6 (FIG. 7). The pivoting connection between each foot 7 and leg 6 is formed by a bolt 13 which extends through an opening 14 in the foot 7 and an opening (not shown here) in a protrusion 25 (FIG. 6, 9) of leg 6. By collapsing feet 7 to the transport position the support 5 can be transported in a relatively small packaging. This is important for limiting the transport costs and, with this, the cost of the seat as much as possible for an end user. Seat surface 2, backrest 3, armrests 4 and all other parts of seat 1 are also packaged as separate components in a transport packaging. In the collapsed position the support 5 will fit easily thereamong.

(16) In order to stabilize feet 7 in the extended operative position, they are in the shown embodiment all connected to each other by a number of connecting elements 15 corresponding to the number of feet 7. In the shown embodiment the connecting elements are each embodied as circle segments so that together they form a ring which wholly surrounds central leg 6. With a view to the stability of support 5 the connecting elements 15 are embodied with tensile and compressive stiffness. They are each mounted with their two ends to the two feet 7 which they connect. Each connecting element 15 is for this purpose provided on both its ends with a flange 16 which can be mounted by means of bolts 17 on the relevant foot 7 (FIG. 8). In the shown embodiment each foot 7 is embodied as a reverse U-shaped profile which is open toward the bottom. In order to enable a firm mounting of connecting elements 15 and the wheels 18 to be discussed below, a reinforcing body 24 (FIG. 9) in which bolts 17 can engage is arranged in the outer end of the hollow profile of each foot 7. As stated, support 5 is further provided with casters 18 which in the shown embodiment are mounted in reinforcing body 24.

(17) Owing to the presence of reinforcing elements 15 the feet 7 can take a relatively light form. In the shown embodiment openings 21 are therefore formed in the side walls 19 and the upper wall 20 of each foot 7. The fact that a reinforcing element 15 extends between each pair of feet 7, whereby reinforcing elements 15 form a continuous ring, has the advantage for users of the seat that they can place their feet on support 5 in any position of the seat surface. This is important because seat surface 2 and backrest 3 are rotatable relative to support 5, whereby seat surface 2 and backrest 3 can take up any random position relative to feet 7. Without a continuous ring of reinforcing elements 15 a user could thus not place his/her feet in the same manner in any position of seat surface 2 and backrest 3, which could result in distraction and annoyance, particularly with gamers.

(18) As stated, as a result of the collapsibility of feet 7 seat 1 can be stored and transported in a relatively compact form. Because reinforcing elements 15 are relatively short and extend only between two feet 7 in the shown embodiment, these reinforcing elements can also be stored and transported in a relatively small packaging. Although it is also possible to envisage forming a continuous ring, which could be connected to each of the feet 7, instead of five separate reinforcing elements, part of the advantage of the compact form would then be lost.

(19) Upon receiving a packaging with the seat according to the invention therein, a user then still has to assemble this seat. All this is shown schematically in FIG. 10. After receiving the packaging with the seat therein (block 100), the receiver will unpack central leg 6 with feet 7 (FIG. 10, block 101 and FIG. 6). He/she will also unpack the connecting elements (block 102). The feet are then extended from their transport position to their operative position extending in radial direction from the leg (FIG. 10, block 103 and FIG. 7), after which connecting elements 15 can be arranged between the adjacent feet 7 (FIG. 10, block 104 and FIG. 8, 9). Wheels 18 can then optionally also be mounted (block 105), although it is also possible to envisage that the seat is not mobile and that small legs or even caps are arranged under feet 7. Support 5 is then ready (FIG. 4) to be assembled with the other components of seat 1; seat surface 2, backrest 3 and armrests 4.

(20) The invention thus provides a seat which can be transported in simple manner, takes up little space during storage and can be assembled in simple manner after transport. The support of the seat is moreover relatively light yet still stiff and stable, and provides a user with a place to rest his/her feet all around.

(21) Although the invention has been described above on the basis of an embodiment, it will be apparent that it is not limited thereto but can be varied in many ways within the scope of the following claims.
