Description

The Innovation concerns a heavy-duty office chair.

office chairs are well known and are being marketed in multiple embodiments kept ready. Such office chairs are usually weight limited, depending on the respective weight The user is getting more and more difficult to find suitable office chairs to find.

By way of example only reference is made to an office chair, which in the DE 10 2008 047 745 is disclosed. This office chair includes for height adjustment a commercial gas spring, over which the office chair is provided raised and lowered. Depending on the user weight, the applicability of conventional gas springs is limited, so that an increased user weight will cause damage to the gas spring in a relatively short time.

aim The object of innovation is a heavy-duty office chair to provide for heavyweight people who are oriented to the practical circumstances of the user weight and beyond that without gas springs and a long Lifespan brings with it.

This in view of the fact that extremely high flexing forces destroying the sealing elements provided in the area of the gas spring. Thus, gas can escape from the gas spring and the office chair sags down.

This Goal is achieved by a heavy-duty office chair, including a seat pan, a back element, as needed Armrests and a footrest connected to the seat pan, wherein the need for movable footboard with an in Direction of the seat facing threaded spindle in operative connection stands, whose free end with an outside of the seat pan lying section of the same is connected.

advantageous Further developments of the heavy duty according to the invention Office chairs can be found in the dependent claims.

In its simplest embodiment includes the threaded spindle an internally threaded tube, one with a corresponding one Externally threaded rod receives and guides.

to Attachment of the threaded spindle at the office chair becomes, a According to further ideas of innovation, the free End of the rod with a plate attached to the seat the seat shell opposite side, in particular detachably, is determinable.

a According to further thoughts of the innovation according to the Possibility, with given armrests the same over Guide elements on the plate connected to the rod To set so that at least one lateral adjustment of the armrests given is.

So far sensible and necessary, can also be a height adjustment the armrests are brought about.

From The advantage is also to produce the foot of die-cast aluminum and to be brought into operative connection with zinc die cast rollers, so that a roll on both carpet and hard floors is possible.

Of the Innovation article has a lifting capacity up to 350 kg, taking out Safety reasons of the renewal Office chair not equipped with a Sitzneigemechanik is.

Of the Innovation object is based on an embodiment shown in the drawing and is described as follows. It demonstrate:

1 to 3 new office chair in different views.

The renewal heavy-duty office chair 1 includes a seat shell 2 , a back element 3 , two armrests 4 as well as a foot part 5 that in this example with roles 6 is in active connection. The renewal office chair 1 is not provided with a seat tilt mechanism for safety reasons. For height adjustment of the office chair 1 comes a threaded spindle 7 used, in this example formed by a with an internal thread 8th provided pipe 9 that with the foot part 5 is in active connection. Inside the pipe 9 is one with a corresponding external thread 10 provided rod 11 essentially free of play. By rotation of the office chair 1 around the vertical axis 12 can be a height adjustment of the seat 2 relative to the foot part 5 be brought about. For the heavy user, it is usually sufficient to make a one-time comfortable height positioning and then keep the same. The seat shell 2 If required, it can be formed from firmly glued shaped-layer woods of predeterminable thickness, on which cushion pads are applied with optimum seating comfort. The armrests can be provided at least laterally adjustable depending on the body size. The pole 11 is in the area of their free end 13 with a metal plate 14 provided, the releasable connection elements with one of the seat surface, not shown 2 ' remote section 2 '' the seat shell 2 detachable ver is bound. Only indicated by arrows is the lateral and height adjustment of the armrests 4 that have guide elements 15 . 16 also detachable with the plate 14 are connectable. Also only is an optional lumbar support 17 ,
