BUCKLE ACCESS LENGTH ADJUSTMENT OF STRAPS, IN PARTICULAR ON Garments PRIORITY : -

The invention relates to adjustable fastening device * !! to the adjustable fastening of two articles or parts of an article together, which are suitable for use with waistbands of trousers and Skirts are suitable to the garments the wearer in proper Way to customize.

In a known type of adjustable fastening device according to British patent specification 358 k ^ h , a strip of flexible material, preferably fabric, has metallic stack-like elements fastened to it at equal intervals, which are raised on the strips, and a sliding element is over the Stripes movable. The sliding element has a releasable tip or points which can engage between adjacent elements, via which the sliding element can be in any of a certain number of positions

Lock length of strip.

Another known adjustable fastener includes a flexible strip of at least two lengthways, cores embedded in a tissue «whereby the tissue has two parallel running, raised ribs covers or forms and a groove formed between the ribs to accommodate a seam line serves. A sliding element can be the length of the strip on the same move and has releasable locking elements for locking in any desired setting.

According to the invention comprises an adjustable fastening device a flexible strip provided with a longitudinal rib and a sliding element old of a limb, by means of which the sliding element is mounted on the rib in order to be able to occupy itself along the rib. Furthermore is a solvable Locking element is provided, which is capable of an adjacent one Move part of the rib in the lateral direction xu and then move the adjacent part between the body member and the releasable locking element to grip the sliding element on the strip in any desired position of the longitudinal adjustment of the spring element to lock on the rib.

In a preferred embodiment, to lock the Qleit- · olementes on dom strips the releasable locking element in one Eichtungcoinii on the limb rotatably movable about an axis, which in a picM.ung perpendicular * to the longitudinal direction of the strip runs. With this * before do. g1_tri A «fsführerungef orm is provided,

According to FIGS. 1 and 3, the fastening device according to the invention shown there comprises an elastic flexible strip 1 made of polypropylene or other suitable plastic material, the strips each being produced using an extrusion process. Two ribs 2, which are made in one piece with a base 3 of the strip, run side by side in the longitudinal direction of the strip, a longitudinal groove k being formed between the ribs (see in particular FIG. 3). Each butt has an incision 5 running in the longitudinal direction in the face facing away from the respective other rib. This cut extends from the base 3 to a head 6 of the rib for sliding a sliding element on the strip in the manner described below. The strip 1 is attached to the waist band 7 of a pair of trousers by means of two longitudinal seam lines 8 (FIG. 1), each of which runs along an edge of the body 3.

A gliding element 9 comprises a body member 1O ₁ which presses the two ribs k (Fig. 3) apart, two flanges 11 of the body member, which are each arranged on one side of the two ribs, oit inwardly bent ends 12 are provided, which into the Incisions in the ribs run in order to hold the Oleitelement on the ribs, while a longitudinal movement of the sliding element against the strip 1 is made possible. A loop portion 13 at one end of the limb is attached to one end portion of a strap 14 which protrudes from one end of a tunnel 15 (Fig. 1) formed by two layers of the waistband. The tunnel runs around the garment on the other side. The belt runs through the

209332/0001

nel, and the other end portion of the belt a (not shown) extends from the other end of the tunnel and is on. a (not shown) A sliding element of a fastening device of a similar type attached, -rich is described below.

2, the body member 10 is provided in the middle between its ends with two upstanding tabs 16, between which a releasable locking element in the form of a tension member 1? is appropriate. The axis of rotation of the locking member is in a direction perpendicular to the longitudinal direction of the strip. A wedge-shaped end 18 of the tension member runs along the axis of rotation downward and is arranged within the groove k between the ribs 2.

In order to adjust the position of the sliding element on the strip 1, the tension member is initially brought into its position shown in dashed lines, see Fig. H. In this position the end 18 of the tension member rests against the outlet of the groove 4 and is out of engagement with the ribs. The sliding element is then brought into a desired position along the strip, in which the effective length of the waist band allows the trousers to fit properly. Ih this position of Gleitalomentes the pulling of tape into his "full drawn Yerriegel> is ngsstellung according to FIG. 1 and taken h. During initial movement of the tension member towards its fully extended position, the wedge-shaped end 18 moves downwardly into the groove k and engages the opposing surfaces of the ribs 2. During a continuation of the downward movement, the end 18 pushes the b * -

adjacent parts of the two ribs to the side in the closed position apart, with the head profile sections of the hips frictionaassig are gripped between the end 18 and the flanges 11 of the limb and the end 18 in an over-center position with respect to the axis of rotation lies.

When the pants are worn, the tension member remains on the Belt 14 and the waist band 7 acting tensions in its Varrieglungsstteilung, around the sliding element in its desired position on the strip 1 see below hold · When the frictional engagement of the tension member and the flange 11 of the ribs 2 is to be released in order to achieve a further adjustment of the position of the Qleitelementes, the tension member by manual operation of the brought fully extended position into the dashed position gea & ss Fig. 4 are to disengage the wedge-shaped end 18 from the ribs 2 move au.

Nevertheless, the adjustable fastening device described above If it is very effective in use, it is of a relatively simple construction before, which is easier to manufacture is all a known · fastening device ait metallic stack-like elements. Furthermore, since the flexible strip in the embodiment according to the invention does not have a fabric cover , difficulties associated with tissue covered are avoided occur, including ensuring a satisfactory end seal and to avoid their fraying.

In a modified embodiment of the invention, FIG. 5 is a Body member 9 of a sliding element 20 old two precisely shaped flanges 21

▼ see, instead of flanges 11, which latter the inwardly bent ends 12 have. The flanges 21 run around convex shaped heads 22 of the ribs 23 of a strip Zk _%, among other things, to slide the Qleiteleaent on the hip and to hold it.

In a further embodiment of the invention, the strip 1 is according to an injection molding process instead of extrusion. With these modified designs, the ribs can be roughened Surfaces or a number of serrations are provided, including their Frictional contact with the locking element or the limb or both subcontractors. Optionally or in addition to a perforation on the Ribs are the limbs of the body with a plurality of teeth to «singing handle provided with the ribs, among other things to increase the friction system between the Qleiteleaent and the flexible strips. Venn a number of teeth on the Flanged and provided on the ribs, the rows of teeth are in locking engagement brought to improve the frictional engagement between the flanges and ribs.

In a further embodiment of the invention, the strip 1 does not exist Waist band 7 can be attached by a welding or joining process.
