"Fastening device for fixing a flexible covering on a support frame for seating furniture η or the like. "

The invention relates to θιπε device for fastening a flexible covering on the support frame or frames of seating furniture according to the preamble of Main claim.

An attachment of the covering to the support frame in seating furniture is known from US-PS 35 12 834. In this known arrangement, which od a garden chair. Like. Describes the to be determined Covering fixed on a fastening rod, which is in a semicircular groove of the support frame can be used. The fixing of the fastening rod against pulling out of the semicircular Groove takes place in that the fastening rod in lateral guide tubes, which transversely run to the fastening rod, is inserted into corresponding openings, so that pulling out of the fastening rod is not possible.

In many cases, this arrangement will meet the requirements technology does not do justice to.

It has therefore already been proposed for seating furniture made of wood or the like, in which Milling a groove opening to the outside into the support frame, into which the covering is inserted. the The covering is then fastened inside the groove via | materials such as nails, screws, fastening

pens or the like, set. The unsightly groove formed in this way is then covered with a decorative piping Locked. This known arrangement has the previous year part that any seat shape with the Bespan-

\ 5 provided and the covering attached to the frame

j, but the disadvantage that the loading

tension only with great manual effort

hcr ^ sSuSliu and again "slcstwsrdsR ksnn se that theoretically if the covering is damaged

; 10 Removal of the covering is not possible.

The upholstery is easy to change, for example when this seating furniture is stored in winter is not possible at all.

15th

The same disadvantages have those fastening devices in which a groove is also provided in the support frame, which is equipped with barb-like undercuts that open to the inside of the groove, a so-called squeeze metal1 is then introduced into this groove with the undercuts. Here, too, it is not possible to detach the covering.
f

j 25 The invention is based on the object

from the generic prior art, one To create covering for seating furniture, in which an easily detachable fixing of the covering on the Support frame takes place, with the fastening of the covering within the groove in the manufacturing facility should be easily feasible for the seating furniture.

This object on which the invention is based is achieved solved by the features of the main claim.

Advantageous refinements are in the Urtterän sayings explained.

In fundamental difference to the above he ^ Refined known arrangements, the invention proposes a fastening device in which a fixation of the covering within the groove takes place via a Kl sünstab, which does not require * that its end faces must be fixed in additional beams. The introduction of the fastening rod can be done "off the roll" so that an easy manufacturing process is guaranteed.

If it is necessary to remove or replace the covering, it is no problem to use the fastening rod pull it out of the fastening groove again, thereby loosening the covering.

With the fastening device according to the invention any seat shape or configuration is possible, because the covering is only on the frame-shaped trained prefabricated support frame by clamping the fastening rod in the fastening groove can be set. 25th

To clarify the idea of the invention this below with reference to the drawing of an exemplary embodiment described, whereby in the drawing

. M.

only a cut through a support frame part, a fastening rod part and - indicated schematically - the covering to be inserted is shown are.

In the drawing, 1 designates a support frame part, which consists of a tubular profile, both

for example made of metal, whereby to reduce weight and an opening 2 is provided within this tubular profile for reinforcing the shape.

With a 3 mounting rod is referred to, which is a
Has core part 4 and ribs 5 arranged on this core part. The ribs protrude beyond the outer circumference of the cylindrical core part 4.

In the support frame 1, a fastening groove 6 is cut out, which widens from its upper opening side 7 to the deepest part of the groove 8 and, seen at a distance from above to the deepest part of the groove, recesses 9 and 10
which are semicircular,

that is, concave from the inside of the fastening groove 6
outwardly curved.

With 10 a covering is indicated.

The dimensional relationships between the size of the core part 4, the fastening rod 3, the width of the
Opening side 7 of the fastening groove 6 and the width in the deepest part of the groove play a role. As an exemplary embodiment, it should be noted that, for example,

have the opening side 7 a width of 5 mm, the
Diameter of the fastening rod 3 over the
Outside of the ribs 5 measured 6 mm, the diameter of the core part 4 about 5.5 mm and the width of the deepest groove 8, preferably again 6 mm.
