FASTENER MAGAZINE STRIPS Description

The invention relates to a magazine strip of the type specified in the preamble of claim 1.

DE-OS 25 41 045 discloses a variant of a magazine strip that is used to hold several screws and is therefore long and can be rolled up. However, for technical reasons, such a long magazine strip can only be used where the corresponding driving tool can work supported on the ground, especially since the large number of screws used represents a particular weight. Such a magazine strip therefore only serves to hold the screws and cannot be fed to a driving tool in a straight line, since it does not have any particular stability due to the necessary ability to roll across the longitudinal direction.

For magazine strips that hold a smaller number of screws, e.g. ten screws, a rigid material is usually used so that precise feeding and precise transport to or in the driving device is possible. Such a magazine strip must therefore have an appropriate cross-section so that the necessary positional stability is achieved in the form of a rigid magazine strip.

On the other hand, it would be useful if the magazine strip were no longer rigid in its longitudinal direction after the fasteners had been driven in and could also be bent or torn off if necessary.

DE-OS 14 78 888 describes a magazine strip of the type specified in the preamble of claim 1. It is a storage strip for a nailing machine in which successive nails aligned parallel to one another, which are inserted into the openings of the flat section, are connected to one another using adhesive strips. For this purpose, longitudinal webs on both sides of the flat section next to the openings are bent upwards or downwards at right angles and placed on the nail shafts. The magazine strip is provided with adhesive so that the bent webs can be glued to the surfaces of the nail shafts. But even this does not create an inherently rigid magazine strip that would be able to accommodate and carry the fasteners on its own. Stability is only achieved here by gluing the magazine strip with its bent side webs to the nail shafts.

The object of the invention is to create a magazine strip which can be punched out of a flexible material, has the rigidity and stability required for storage and for feeding to the driving tool and can be easily bent again after leaving the driving tool.

This object is achieved according to the invention by the features specified in claim 1.

By bending a web at a distance from the openings at least along one longitudinal side edge of the magazine strip, according to the invention, an L- or U-shaped cross-sectional profile can be produced, which gives the magazine strip flexural rigidity.

Furthermore, the measures according to the invention mean that the magazine strip can be made from a relatively thin sheet material and is therefore inexpensive to manufacture. A cardboard strip can also be used. As soon as the side web of the magazine strip is bent to one side, the magazine strip has sufficient stability so that even a magazine strip fitted with relatively heavy screws can hardly bend despite being made from cardboard. This means that despite using a cheap material (e.g. cardboard), which can also be punched very easily, a rigid magazine strip can be created. After the fasteners have been driven in, i.e. when the magazine strip leaves the driving device in an empty form, the web can be bent open again in a very simple way, either completely or partially, so that it is again aligned with the plane of the magazine strip itself, so that the magazine strip can then be easily bent upwards or downwards. This is particularly advantageous if work is to be carried out in a corner of a room or in other hard-to-reach places.

By means of the measures according to the invention, a magazine strip can be made from relatively thin material, whereby the inserted screws are nevertheless held securely and a secure and precise alignment of the screws within the magazine strip and thus in the driving device is ensured.

Advantageous embodiments of the invention form the subject matter of the subclaims.

Embodiments of the invention are explained in more detail below with reference to the drawing.

Fig. 1 is a plan view of a blank of a

magazine strip;

Fig. 2 ., an oblique view of the magazine strip

with bent web and a screw inserted into the magazine strip;

Fig. 3 a cross section through a magazine

strips of the embodiment according to Fig. 1 and 2;

Fig. 4 a cross section through a magazine

strips with a bridge on both sides.

A magazine strip 1 is designed to accommodate and hold fasteners 2. For this purpose, a series of openings 3, spaced apart in the longitudinal direction of the magazine strip 1, are provided for inserting or screwing in the fasteners 2. The openings 3 are assigned crosswise incisions 4, which also merge into smaller openings 5. This measure makes it easy to screw a fastener 2 through the magazine strip 1. Individual tabs 6 formed by the incisions 4 can bend downwards to allow a screw head 7 to pass through.

The magazine strip 1 is conveniently made of cardboard, but for the intended use it would also be possible to manufacture it from plastic or a relatively thin metal strip.

What is important in the magazine strip 1 described here is that a bendable web 8 is provided along one of the longitudinal edges, so that by bending this web 8 an L-shaped cross-sectional profile can be created for the magazine strip. This gives the magazine strip 1 the required stability in its longitudinal direction despite the use of a material that is not inherently rigid.

As can be seen from Fig. 4, it is also possible to provide webs 8 on both sides of the longitudinal edges of the magazine strip 1. This can create a stable structure, particularly when relatively heavy screws are to be accommodated.

A magazine strip, e.g. made of cardboard, can be created that ensures that the screws are safely inserted into a driving tool and that they are held in place until they are driven in. If these webs 8 or the web 8 in a one-sided arrangement extend over the entire length of the magazine strip 1, this stability is also provided over the entire length of the magazine strip.

A particularly useful design is that perforation cuts 10 are provided between a flat section 9 of the magazine strip 1 and the bendable web 8, extending over the entire length. This creates a predetermined bending edge 11, so that the web 8 can be easily bent along a predetermined line. The special design of the perforation cuts 10 also ensures that the web 8 not only bends easily, but also remains in this bent position.

It is of course also possible to provide only one bending notch, but then there is always the risk that the web 8 will straighten up again and over time will be aligned with the flat section 9 again. Depending on requirements, different perforation cuts 10 can also be provided here, for example cuts arranged one after the other in one direction with continuous ribs remaining between them. It would also be conceivable to provide small punctures or openings in a row in order to form the specified bending edge 11.

The web 8 or the webs 8 are provided with a bevel 12 at least at one of their longitudinal end areas, whereby the magazine strip 1 can be more easily inserted into the corresponding driving tool.

As already stated, the design of the magazine strip 1 described here can achieve proper stability and strength, while the magazine _strip

strip can be bent again after leaving the driving tool. It is therefore also conceivable to make the magazine strip 1 rollable with a corresponding length, whereby in the rolled position the web 8 and the flat section 9 of the magazine strip 1 lie in one plane and the web 8 is bent downwards in good time before the magazine strip is fed to the driving tool. Simply by arranging a bendable web 8 on one or both sides, a stable magazine strip is created, which can be made from relatively thin and inexpensive material.
