Definitions
- the invention relates to a clamp connection for upholstered furniture and a method for producing such a clamp connection. It also relates to a method for releasing such a staple binding.
- clips are a widely used connecting means for attaching cover fabrics to an upholstered furniture frame made of wood or wood-based materials.
- Cover or molded parts made of cardboard or plastic are also attached to a frame.
- clamp connections are linear, i.e. the brackets are usually placed in a line with a small distance between them.
- clamp connections are made in the area that is not directly visible, for example by covering them with the upholstery material.
- Textile straps and metal or plastic tabs of flat springs are also attached to the frames of upholstered furniture by means of a clamp connection.
- DE 27 07 466 discloses a device for removing staples, which are used for fastening the cover material of upholstered furniture.
- a lever arm provided with a tip is provided, with the end of the lever arm carrying the tip being rotatable about a first pivot point.
- the pliers shoe is connected, which consists of two pliers jaws enclosing the tip and the front end of the lever arm, and the pliers jaws have a second pivot point at their end opposite the tip.
- the object of the invention is to eliminate the disadvantages of the prior art.
- a clamp connection for upholstered furniture is to be specified which is as durable and secure as previous clamp connections, but can be easily loosened and removed.
- a method is to be specified with which such clamp connections can be produced.
- a method for producing such a clamp connection and a method for releasing such a clamp connection are to be proposed.
- a clamp connection for upholstered furniture in which an upper material, for example the cover material, is fastened to a lower material, for example the frame material, with a plurality of clamps, a band being arranged between the upper material and the back of the clamp.
- the band is preferably 3 to 6 mm wide. Its length corresponds essentially to the length of the clamp connection. At one end of the clip connection, part of the tape should protrude freely above the upper and lower material in order to enable the clip connection to be released easily by starting to pull off the tape at this point of the tape.
- the band can be made of different materials such as textile materials or plastic materials. It is preferably so firm that when the tape is pulled off the upper material, the legs of the clips are completely pulled out of the upper and lower material, the clips remaining in the tape. If tapes made of a less rigid (flexible) material are used, this must be so firm that at least one leg of each clip is pulled out of the upper and lower material when the tape is pulled off. Accordingly, the strength of the tape should be high enough to withstand a clip pull force of at least 300 N to prevent the tape from tearing during peeling.
- a band made of flexible material is expediently used when clamp connections with narrow radii are to be produced.
- the upper material can also be upholstery materials or cover or molded parts made of cardboard or plastic, which are to be fastened to a lower material, in particular the frame material, by means of a clamp connection.
- the base material which usually forms the frame of the piece of furniture, consists of preferably made of wood or wood-like materials such as wood composites.
- the clamp connection according to the invention offers the advantages of the conventional clamp connection, namely high strength and durability of the connection and easy manufacture of this connection.
- it has the essential advantage that the inherently firm and durable connection can be easily released by pulling off the tape, which makes it possible to easily upholstered furniture into its individual components, namely the upper material and the lower material, can be disassembled. The individual materials can be recycled separately, so that economically viable recycling of upholstered furniture is possible.
- the clamp connection according to the invention can be produced by a method which comprises the following steps:
- the tape is expediently applied in such a way that a part of the tape protrudes freely above the upper and lower material, in order to enable the clip connection to be released easily by starting to pull off the tape at this point of the tape.
- the method is preferably carried out with the aid of a pneumatic stapling device, a band feed and cutting unit being integrated in this device, so that the band is positioned on the upper material with a precise fit when the clamp is hammered in by the band and the upper material in the lower material.
- the clip connection according to the invention can be released by pulling the tape off the upper material, the clips either being pulled completely out of the upper and lower material or at least one leg of each clip being pulled out of the upper and lower material.
- original processing line is understood to mean the direction in which the clamp connection was established by successively driving in the clamps.
- the tape can be pulled off by machine. To do this, the protruding end is clamped onto a take-up unit.
- the reel-up unit can rotate about an axis which is guided parallel to the clamp connection by a translational movement.
- the tape is wound onto the take-up unit.
- the take-up unit can be driven electrically.
- the clips are pulled out of the lower and upper material, where they stick to the band.
- the tightening of the band means that at least one leg of each clamp of the clamp connection is pulled out of the lower and upper material, whereby the clamp connection is loosened to the extent that the upper and Bottom material can be easily separated from each other. In the latter case, the tape breaks in the area of the clip. In any case, the strength of the band must be so high that the band does not tear completely.
- Fig. 1 is a schematic sectional view of a clamp connection according to the invention
- FIG. 2 shows a schematic sectional illustration of the clamp connection shown in FIG. 1 during the detachment of the band from a solid material
- FIG. 3 shows a schematic sectional illustration of the clamp connection shown in FIG. 1 during the detachment of the tape from a flexible material.
- FIG. 1 shows a section of a clamp connection in upholstered furniture, in which the band 1 as the uppermost layer above the cover material 3, which forms the upper material, is fixed to the frame 4 together with the cover material 2 by a series of clamps 2.
- the clips 2 are introduced in such a way that their legs 2.2 penetrate the tape 1, the cover fabric 3 and the frame material 4, while the back 2.1 of the clips 2 rests on the top of the tape 1.
- the free end of the band 1 is gripped and, if necessary with the aid of mechanical and / or electrical reeling units, pulled off the cover material 3 and the frame material 4 against the original processing direction. If the band 1 has sufficient strength, as shown in FIG. 2, the clips 2 are completely pulled out of the cover material 3 and the frame material 4. If a less strong, ie flexible, tape is used, the clips 2, as shown in FIG. 3, are not completely pulled out of the cover fabric 3 and the frame material 4. However, they are opened on one side by pulling a leg 2.2 of each clip 2 out of the cover material 3 and the frame material 4 while deforming the clips 2. It is essential that the tape 1 does not tear completely, but the crack formation is limited to the back of the clamp 2.1. List of the reference symbols used
