Description

The invention relates to a folding chair, comprising a frame and a seat cover which is detachably connected to the frame, wherein the seat cover is attached via at least one holding body to the frame.

In particular foldable folding chairs, but also foldable folding chairs often have a formed from a fabric seat cover. The seat cover is usually single-ply and consists of a textile fabric made of natural or synthetic fibers with net-like or dense mesh. It is known to attach the seat cover directly to the frame. For this purpose, the seat cover, for example, on the edges facing the frame tabs, which are wrapped around the frame during assembly, thereby forming a loop. The loop wrapped around the frame is attached to the seat cover by means of a seam, adhesive or ultrasonic welding. As a result, the seat cover is permanently connected to the frame. Subsequent replacement of the seat cover is not possible.

It is also known to introduce openings, for example bores, into the frame, the seat cover having holding bodies in the form of tabs with hook-shaped ends, the ends being hooked into the openings. The tabs are often designed as loops made of textile, with hooks of metallic material are secured in the loops.

Furthermore, it is known to attach the seat cover on holding body to the frame. The holding bodies have first holding elements attached to the seat cover and second holding elements fastened to the frame. Here are the second holding elements attached to the frame Part of the frame and firmly connected to it. The mounting of the second holding elements takes place before the frame is completely assembled. Subsequent replacement of the second holding elements is therefore not possible. This complicates the installation and repair of the folding chair. In this embodiment, the attachment of the seat cover also takes place at the factory. Relevant documents of the prior art are US 2010/235987 A1 . CH 593 041 A5 and GB 2 344 510 A ,

The invention has for its object to provide a folding chair, the seat cover can be attached by simple means in the frame and removed again.

This object is achieved with the features of claim 1. In advantageous embodiments, the dependent claims relate.

The folding chair for solving the problem comprises a frame and a seat cover which is detachably connected to the frame, wherein the seat cover is fastened to the frame via at least one holding body, wherein the holding body has a first holding element associated with the frame and a second holding element associated with the seat cover has, wherein the first holding element is positively connected to the second holding element.

In this case, the first retaining element may be releasably secured to the frame and the second retaining element may be fixed to the seat cover.

The folding chair according to the invention thus consists of the elements frame, seat cover and holding body. The holding body has two holding elements, of which a first is fixed to the frame and a second to the seat cover.

The frame associated with the first holding element is formed according to the invention in the form of a sleeve. The sleeve encloses the profile of the frame. In this embodiment, the frame is preferably composed of frame segments. For assembly, first frame segments provided and the first holding elements pushed onto the frame segments. Subsequently, the frame segments are mounted to the frame. In this embodiment, the first holding elements is advantageous in that the first holding elements captively held on the frame and are also rotatably mounted on the frame. In addition, the first holding elements are robust and inexpensive to produce.

The retaining element fixed to the frame may be releasably secured to the frame. This makes it possible to first produce the frame, or to assemble the necessary for the folding chair frame parts to a complete frame. The required holding elements can then be attached to the frame. Thereafter, the seat cover provided with the second holding elements can be buttoned into the frame. This is done by connecting the first holding elements with the second holding elements. It is particularly advantageous that the attachment of the first holding elements can be done after completion of the frame. This simplifies the production of the frame.

In both embodiments of the first holding elements, it is not necessary to make the assembly of the seat cover already factory. The assembly of the seat cover can be done later, for example by the user of the folding chair. Furthermore, it is conceivable to provide different seat covers for a folding chair, which can be buttoned into the frame alternately. In this context, it is particularly conceivable to provide seat covers for use in summer and seat covers for use in winter. For summer suitable seat covers, for example, have a network structure with coarse air and water permeable mesh, while the suitable for winter seat cover with a thermal insulation, for example, can be provided in the form of an additional cushion.

According to the invention, a holding element is designed as a holding eye and a holding element as a hook. In this case, according to the invention forms the retaining element formed as a holding eye the first holding element and the hook formed as a holding element, the second holding element. A hook and eye connection is particularly easy and without tools to produce. This allows the mounting of the seat cover for inexperienced users. A hook / eye connection can also take high loads. If the connection is preloaded, no unintentional release is possible.

The first holding element may have a sleeve, which is designed such that the first holding element is releasably clipped onto the frame. Folding chairs usually have a tubular frame, which is composed of metal tubes with a round cross-section. The first holding elements according to the invention have a sleeve which essentially corresponds in its inner diameter to the shape of the frame. The fact that the first retaining element can be clipped onto the frame, the attachment of the first holding elements is particularly simple. The assembly of the first holding elements can be done after completion of the frame. In addition, the first holding elements are captively held on the frame.

Another advantage of this embodiment is that the sleeve of the first holding element can rotate on the frame. As soon as a user lies down on the folding armchair or the seat cover, the seat cover is deformed. As a result, the seat cover is no longer aligned parallel to the frame. Due to the configuration of the first holding element with a sleeve for attachment to the frame, the first holding element can follow by twisting the deformation of the seat cover. As a result, the connection between the first holding element and the second Retaining element claimed only to train, as it is the case with an unloaded seat cover.

Preferably, the sleeve is provided with a slot. The slot allows the spreading of the sleeve so that it can be clipped onto the frame.

In order to simplify the spreading of the sleeve during assembly, a hinge may be arranged on the opposite side of the slot. This joint may be in the form of a hinge, for example in the form of a film hinge.

Depending on the choice of material but the joint can also be omitted. If the sleeve, for example, consists of an injection-moldable plastic, the sleeve can be spread over the slot, wherein the sleeve automatically closes after clipping on the frame due to the resilient material properties of the plastic again.

The holding eye is assigned according to the invention the first holding element and the hook is assigned according to the invention the second holding element. Preferably, the second retaining element is attached to the seat cover, that sets a spring action. This can be done by attaching the second holding element to the seat cover via elastic loops or the like. Alternatively, it is conceivable that the seat cover has elastic, resilient properties. In this case, the handling and assembly of the seat cover is easier when the hooks are assigned to the seat cover. The eyelets associated with the frame, on the other hand, are comparatively rigid.

The second holding element is fixed according to the invention via a loop on the seat cover. In this case, the loop may be elastic. This allows the resilient application of the seat cover to the frame regardless of the choice of material of the seat cover. It is ensured that the holding elements are always under tension.

Especially in the case of a padded seat cover, the elasticity of the seat cover is possible only within certain limits. Due to the elastic connection of the second holding element via loops, however, results overall in a higher elasticity. This improves on the one hand the mounting of the seat cover in the frame and on the other hand increases the seating comfort due to resilient properties.

The hook may be formed from the second holding element and have a projection with a thickening arranged at the free end of the projection. The second holding element preferably consists of an injection-moldable material. Projection and thickening are the same material and integrally formed from the second support member.

The holding eye can be formed by a keyhole-shaped opening. In this case, the portion of the opening with the larger diameter is associated with the frame, while the portion of the opening with the smaller diameter points in the direction of the seat cover. The projection of the second holding element can be introduced through the section with the larger diameter. Subsequently, the hook slides in the smaller diameter portion, wherein the projection protrudes through the opening of the retaining eye, wherein the thickening is blocked in this section. Due to the elastic bias of the seat cover fastened in the frame, the two holding elements can not detach from each other automatically, the projection is held in the small-diameter portion. The two holding elements are positively connected to each other via the hook and eye connection.

According to the invention, the first retaining element is provided with a tab arranged on the sleeve, the retaining eyelet being associated with the tab. In this embodiment, the holding lug is particularly easy to reach, so that facilitates the assembly of the seat cover in the frame.

The slot can divide the tab into two tab parts. In this embodiment, the assembly of the first holding element is carried out by spreading the sleeve, wherein the frame between the two tab parts is inserted into the first holding element. The opening is arranged in both flap parts, so that the hook passes through both flap parts after assembly of the seat cover and thereby prevents the first holding element unintentionally detached from the frame.

The invention also relates to a folding lounger with the features of claim 8. The advantageous embodiments described in the dependent claims, or equally apply equally to the folding lounger.
