Definitions

• the present invention relates to a string for use as a carrying or fastening device in article clothing and other objects worn on the body and which string is intended for stretching around parts of the body and has at least a first string end and that a first part of a lock is secured to the first string end which part is intended for co-operating with a second part of the lock and that the two parts of the lock has a strain capacity which is smaller than the strain capacity of the string as seen in the axial direction of the string.
• the present invention also relates to a lock for use in connection with the string according to the invention as well as the use of such a string.
• DE 1,230,603 describes a lock for use in connection with clothing, among other things.
• the lock consists of a first part and a second part which are intended for en ⁇ gagement with each other in order to join the two parts of e.g. an article clothing.
• the first part of the lock comprises a head shaped as a hammer-head
• the second part of the lock comprises a recess which is intended to engage with the head on the first part.
• the coupling of the first part and the second part takes place by introducing the head on the first part into the recess on the second part. At a certain strain of the two parts the coupling may be broken.
• the two parts are secured to e.g. an article clothing by performing a welding of the article clothing in the plastic material from which the lock has been made.
• the lock which has been described in the above-mentioned citation possesses different drawbacks.
• the coupling of the first part and the second part of the lock takes place with a lock which is not symmetrical of rotation.
• a certain strain upon which the lock is suppose to break is not unambiguous.
• the first part and the second part of the lock are secured to e.g. an article clothing by welding the article clothing in the parts ofthe lock.
• Another embodiment of a string according to the invention comprises a first string end and a second string end which has a minimum sectional width in which the first and second part of the lock is provided with tracks for the engagement of the first respec ⁇ tively second string end which tracks are U-shaped and extend substantially parallel with the longitudinal direction of the first and respective part of the lock and is pro- vided with barbs with a mutual distance which is smaller than the minimum sectional width ofthe first respectively second string end.
• the other embodiment of the string according to the invention is characterised in that the barbs are directed inwards from the forked branches of the U and forwards to the foremost end of the respective part of the lock, and that the first and second string ends are led down between the forked branches of the U with the foremost end of the respective string end which is located between the barbs and the foremost end of the part ofthe lock.
• the lock is of the type which does not show a destructive deformation in case of breakage. When the lock breaks it will be possible with such a lock to subsequently join the lock again, thus making use ofthe string once again.
• the lock is of the cylindrical spring lock type.
• This lock consists of a he part and a she part.
• the she part consists of a cylinder part which is provided with a recess facing inwards from an inner cylinder surface.
• the he part consists of a tubular part with a groove facing inwards from an outer side of the tubu- lar part. The tubular part which constitutes the he part is intended to be introduced into the cylinder part, thus the groove engages with the recess.
• the string shows two halves with a first string end and a second string end which both are provided with end-splices.
• the first part and the second part ofthe lock are provided with tracks for the engagement ofthe first respectively second string end which tracks are U-shaped and extend substantially parallel with the longi ⁇ tudinal direction of the first respectively second part of the lock.
• the tracks are pro- vided with barbs with a mutual distance which is smaller than the sectional width of the end-splices which barbs are directed inwards from the forked branches of the U and downwards to the bottom ofthe U.
• the first and the second string end are secured to each part of the lock in such a manner that the two string ends are led down be ⁇ tween the forked branches ofthe U with the end-splices located between the bottom of the U and the barbs.

• the second section 14 with the lock device proper comprises a U-shaped track which in the illustrated drawing is shown as seen down through the forked branches 15 ofthe
• the U- shaped track extends parallel with the longitudinal direction L ofthe respective part of the lock.
• the U-shaped track is provided with barbs 16 extending inwards from the forked branches 15 ofthe U and forwards to the first section 12 of the respective part ofthe lock 4.
• a distance b between opposite barbs 16 is smaller than a sectional width B of the string 1.
• the string end 13 is led down in the U-shaped track thus a foremost end 17 of the string end is located between the barbs 16 and the first section 12 of the respective part of the lock.
• the string 1 is thus secured to the respective part of the lock 4 and may not be released, even if the string 1 is exposed to a pull in the longitudinal direc ⁇ tion L.
• the first section 12 comprises a fork with a first prong 18 and a second prong 19 with mutual distance A.
• the prongs of the fork 18,19 extend forwards parallel with the longitudinal direction L.
• An outer end 20 of the prongs of the fork 18,19 is provided with a stop 21 which extends towards the centre of the fork. Between the stops 21 there is a mutual distance a which is smaller than the distance A between the prongs of
• the opposite identical second part 11 ofthe lock is turned 90° around the longitudinal direction L in relation to the first part 10 of the lock.
• the opposite second part 11 of the lock 4 is illustrated in sections thus the inner surface 22 of one ofthe prongs ofthe fork is visible.
• Fig. 3 illustrates another embodiment of a lock 4 according to the invention for use in connection with the string 1 according to the invention.

• the first section 12 comprises, however, another type of locking device.
• a first part 10 of the lock 4 has a first section 12 which comprises of a part 26 of a cylinder hav- ing a diameter C.
• the cylinder part 26 is on an outer cylinder surface 27 provided with a recess 28.
• the recess 28 extends along the entire circumference of the cylinder part 26 and has a bottom diameter c which is smaller than the diameter C.
