Description

69958 1 Sealing tape product and method of making the same

The invention relates to a closure strip product comprising two elongate continuous strips of flexible fabric material, the strips having closure members which lock the strips of the strip pair together, the two strips being provided with strips and periodically closed closure members 10 forming individual pairs of independent closure members and adapted to interlock with each other so that the strips of the pair of strips overlap the flange edges and the oppositely arranged rows of closure members lock substantially transversely to the plane of the pair of strips by a substantially opposite pulling motion, the two strips of a pair of strips being identical to each other, comprising "two-piece" male female closure members.

Various pushbuttons are known in the art and are used in many different applications. Push buttons are most commonly made of metal by stamping. Known pushbuttons are most commonly attached to fabric, leather or the like by riveting with special tools. When pushbuttons are made of metal, their manufacturing technique and material place considerable limitations in the choice and shape of the pushbuttons. Another disadvantage is that the pushbuttons have to be attached one by one to garments or the like, which requires a relatively large amount of manual work, which increases the cost of the accessories or the like. Often known pushbuttons come loose, usually by tearing, and getting a new one in place requires special tools and often a professional.

With regard to the state of the art incidental to the present invention, reference is made, by way of example, to GB Patent 1,058,097 and DE-A-19 19 098, which disclose methods of making push-buttons as a continuous strip from which individual push-buttons are cut and fastened by methods known per se. using.

2,69958 1 For pushbuttons, reference is further made to U.S. Patent 3,181,219, a combination of which is known in which fully finished pushbuttons made of metal are attached to an auxiliary tape and the male and female tapes thus obtained are joined together so that such a pair of tapes can be easily and quickly attached. garments or the like. The combination according to this patent offers certain advantages, but this solution does not eliminate the disadvantages associated with pushbuttons in general and their manufacture. It should be reiterated here that the material and manufacturing technique of the pushbuttons place limitations on the choice of the design of the pushbuttons and make it difficult to design the buttons to suit each application.

On the other hand, several different zippers are known, the structure of which is characterized by two strip bands with rows of closure members at the edges, which fasten and open with a special lock in the lateral direction of the closure member rows. Despite the development of zippers, the rows of pushbuttons are cheaper than zippers in some applications. Some applications use both push-button rows and zippers.

Various adhesive tapes are also known, for example, U.S. Patent 3,778,870 and CH Patent 495,122. Attaching Velcro straps to garments or the like is in itself relatively easy and quick, but their grip is not nearly as good as that of push-button rows. The disadvantage of adhesive tapes is also that they gradually lose their adhesion with age.

With regard to the state of the art related to the invention, reference is also made to U.S. Pat. No. 3,890,679, which discloses a method for casting plastic pushbuttons on small textile tags which adhere to the tape tags during molding. These patches are then each individually sewn onto garments or the like to provide a row of push buttons. As previously stated, this type of pushbutton attachment is slow and cumbersome, as well as work requiring space, special equipment and special personnel.

For the state of the art most closely related to the invention, reference is made to application publication DE-OS 1960185.

11 '69958 1 It is an object of the present invention to provide a product which avoids the above-mentioned drawbacks. The object of the invention is, above all, to provide a product which offers advantages in the textile industry and in general in the fastening of closing rows, so that all of the often relatively automated methods which are accustomed to being used, for example in connection with fastening chains, can be used.

The object of the invention is to provide a new type of sealing tape product which is advantageous in its manufacturing method and which combines as far as possible the advantages of zippers and push-button rows and velcro strips, but at the same time eliminates the disadvantages discussed above.

The present invention has started to further develop a barrier strip product in which the opposing strips are identical to each other, which is important for the economics of manufacturing the product. It is a further object of the invention to provide a barrier strip product which is more usable, in particular easier to lock and open than previous barrier strips, and which has a self-tightening structure against lateral tension.

20

In order to achieve the above and later objects, the closure strip product according to the invention is mainly characterized in that the female locking members of the strips have a wider perforated part and an associated tapered perforated part. the pin-like protruding portion of the closure member wedges into said narrower hole portion when said lateral pull is applied to different strips of the pair of strips.

30

The invention will now be described in detail with reference to some embodiments of the invention shown in the figures of the accompanying drawing, to the details of which the invention is in no way narrowly limited.

Fig. 13 shows, in a manner similar to Fig. 2, two overlapping male / female strips interlocked.

Figure 4 shows a top view of the second male-female closure strip.

Figure 5 shows a section XV1I-XVII in Figure 4.

Figure 6 shows two overlapping male-female straps interlocked.

In order to produce the cowardly strip product of the invention, closing members are cast on a continuous flexible strip, for example a textile strip, at regular intervals, preferably at regular intervals.

At the same time, they are reliably and practically firmly attached to the strip during casting. Perforation of the strip before the casting step is not always necessary, but especially with man-made strips, the casting parts can be reliably "melted" in connection with the strip.

In the following, some various preferred structural examples of a pair of closure strips according to the invention as well as applications are described.

Figures 1, 2 and 3 show a laterally self-locking combined male-female tape, which has the advantage that only one type of tape is required to form the reading tape. The "two-way" strip shown in said figures consists of elements 40 which, in opposition to a similar element 40 ', form a pair of self-locking closure members when laterally tightened. Elements 40 and elements 40 ', respectively, have a protruding portion adjacent the hole portion 43 having a neck portion 41 and a cap portion 42. The neck portion 41 is semicircular in cross-section and abuts an oblique surface 47 from the hole 43 side. . Behind the hole part 47 35 there is a planar expansion surface 45, in connection with which the shoulder of the hat part 42 is locked. The extension of the planar surface 45 is a chamfer 46.

69958 1 Figure 3 shows how the "two-way" parts 40 and 40 ', which are identical, interlock under the guidance of the planar surfaces 47. When the strip 10 is exposed in Figure 3, the tow direction of arrow A, and accordingly the tape 10 in the opposite direction B, a lateral self-locking closure member 5 a pair. In this case, there is a clearance A between the opposing inclined surfaces 47. When the pair of members 40, 40 'is opened, the surfaces 47 are brought against each other, whereby the hat part 42 is caused to detach from the connection of the shoulder surface 45 and the lock is released. The surfaces 47 and the associated roundings 48 of the hat part 42 act as guide surfaces which allow the members 40 and 40 'to be easily guided in contact with each other and thus locked in the position shown in Fig. 3.

Figures 4, 5 and 6 show a modification of the application example described above, comprising "two-way" closure members 50 and 50 ', which are identical and interlocked as shown in Figure 18. The structure is essentially as described above, comprising a neck portion 51 associated with the base portion, which is extended by a hat portion 52. The base and neck portion 51,52 abut a sloping surface 57 joined by a circular surface 58. The hole portion is formed by a wider portion 53 and a narrower portion associated with the surface 57. a portion 53 'to which the neck portion 51 fits and locks when the straps 10 and 10' are loaded in opposite directions A and B as shown in FIG. In connection with the hole 53,53 'there is a planar shoulder surface 54 and an extension chamfer 55. The structure is self-locking as shown in Fig. 18 and a relatively large clearance is left between the surfaces 58, which allows said surfaces 57 to be pressed against each other by pressing the strips 10 and 10 'of the arrow A and B in the opposite direction, the lock will open very easily. Correspondingly, the locking is very easy to lock in a self-guided manner due to the roundings 58 of the hat part 52.
