Abstract

A device for tightening laces, strings and like elongated and flexible elements having free ends, wherein the device comprises an outer sleeve (1) and an inner spring-biassed lock plunger assembly (2) which can be moved axially in the sleeve. The sleeve and the lock plunger assembly have through-penetrating, mutually corresponding holes at right angles to the longitudinal axis of the sleeve and assembly respectively. The free ends of the element are intended to be inserted through these holes after having moved the lock plunger assembly in the sleeve to a position in which the holes are in register with one another. The sleeve (1) and the lock plunger assembly (2) both have two through-penetrating, end-receiving holes (10, 11 and 20, 21 respectively), the distance between the holes (10, 11) in the sleeve (1) being shorter than the distance between the holes (20, 21) in the lock plunger assembly (2). A spring-force generating spring (23) is mounted between two parts (22, 24) of the lock plunger assembly (2), each of these parts being provided with a respective one of the two holes (20, 21) in the lock plunger assembly.

FÖREDHAGEN UTFÖRINGSFOHM Spánnorganet enligt Fig 1 omfattar en hylsa 1 och en i hylsan inlagd låskolvanordning 2. Låskolvanordningen består av en övre del 22, en nedre del 24 och en delarna 22 och 24 sammanhållande fjäder 23.PREFERRED EMBODIMENT The clamping means according to Fig. 1 comprises a sleeve 1 and a locking piston device 2 inserted in the sleeve. The locking piston device consists of an upper part 22, a lower part 24 and a spring 23 holding parts 22 and 24 together.

Av Fig 2 framgår att hylsan 1 har två hål 10 och 11, vilka är avsedda för införing av t.ex. ett skosnöres ändar. Hålet 10 har avlång form vinkelrätt mot hylsans längdriktning och med hålets långsidor utformade med en spets 101 mitt på resp. långsida in mot hålets centrum. l hylsans 1 längst från hålet 10 belägna ände finns en bågtormig urtagning 12, vilken underlättar att låskolvanordningen 2 kan inskjutas i hylsan så att närmast belägna hål 11 resp. 21 i hylsan och låskolvanordningen blir koaxiella. En kant 13 vid hylsans 1 övre ände utgör ett stopp för låskolvanordningens rörelse uppåt i hylsan, se även Fig 4.From Fig. 2 it appears that the sleeve 1 has two holes 10 and 11, which are intended for insertion of e.g. the ends of a shoelace. The hole 10 has an elongate shape perpendicular to the longitudinal direction of the sleeve and with the long sides of the hole formed with a tip 101 in the middle of resp. long side towards the center of the hole. In the end of the sleeve 1 furthest from the hole 10 there is an arcuate recess 12, which facilitates that the locking piston device 2 can be inserted into the sleeve so that the nearest holes 11 resp. 21 in the sleeve and the locking piston device becomes coaxial. An edge 13 at the upper end of the sleeve 1 constitutes a stop for the upward movement of the locking piston device in the sleeve, see also Fig. 4.

Av Fig 3 framgår att låskolvanordningen 2 har två hål 20 och 21 med hålet 20 i den övre delen 22 och hålet 21 i den nedre delen 24. Hålet 20 har samma form som hålet 10 i hylsan 1 och hålet 21 har samma form som hålet 11 i hylsan 1. Avståndet mellan hålen 10 och 11 är mindre (ca 1,5 cm) än avståndet mellan hålen 20 och 21 när fjädern intar viloiäget. l den övre delen 22 är en del närmast hålet 20 väsentligt smalare närmast hålets mot fjädern 23 vända sida än delen i övrigt, så att en läsningen av ett instucket skoband för- 505 370 3 stärkande kam 221 bildas mot hålet 20. Detta framgår tydligt av Fig 5. Vidare har delen 22 en kant 25, svarande mot kanten 13 i hylsan 1. l den nedre delen 24 är den längst från hålet 21 belägna ändytan cirkulärt (konvext) ut- formad.From Fig. 3 it can be seen that the locking piston device 2 has two holes 20 and 21 with the hole 20 in the upper part 22 and the hole 21 in the lower part 24. The hole 20 has the same shape as the hole 10 in the sleeve 1 and the hole 21 has the same shape as the hole 11 in the sleeve 1. The distance between the holes 10 and 11 is smaller (approx. 1.5 cm) than the distance between the holes 20 and 21 when the spring assumes the rest position. In the upper part 22 a part closest to the hole 20 is substantially narrower closer to the side of the hole 23 facing the spring 23 than the rest of the part, so that a reading of an inserted shoe band reinforcing cam 221 is formed against the hole 20. This is clear from Fig. 5. Furthermore, the part 22 has an edge 25, corresponding to the edge 13 in the sleeve 1. In the lower part 24, the end surface located furthest from the hole 21 is circular (convex).

Det i det föregående i princip beskrivna spännorganet skall nu visas i anslutning till an- vändning på ett skosnöre.The tensioning member described in principle above must now be shown in connection with the use of a shoelace.

Den i Fig 1 delvis utstickande övre delen 22 av Iåskolvanordningen 2 har i Fig 7 tryckts ned med tummen så att låskolvanordningens hål 20 kommer mitt för hylsans hål 10; ett skosnöres två fria ändar kan nu träs genom de två hålen 10-20, varpå delen 22 släpps.The upper part 22 of the locking piston device 2 partially protruding in Fig. 1 has been pressed down with the thumb in Fig. 7 so that the hole 20 of the locking piston device comes opposite the hole 10 of the sleeve; the two free ends of a shoelace can now be threaded through the two holes 10-20, whereupon the part 22 is released.

Den i Fig 1 delvis utstickande nedre delen 24 av Iåskolvanordningen 2 har i Fig 8 mot fjäderkraften 23 tryckts in med tummen så att låskolvanordningens hål 21 kommer mitt för hylsans hål 11; skosnörets ändar kan nu träs genom även de två hålen 11-21, varpå delen 24 släpps.The lower part 24 of the locking piston device 2 partially protruding in Fig. 1 has been pressed against the spring force 23 in Fig. 8 with the thumb so that the hole 21 of the locking piston device comes in the middle of the hole 11 of the sleeve; the ends of the shoelace can now be threaded through also the two holes 11-21, whereupon the part 24 is released.

När nu skosnöret är trätt genom hålen i båda ändar av spännorganet utvidgas fjädern 23 och låser därigenom skosnöret på två ställen i spännorganet, se Fig 9.Now that the shoelace has passed through the holes at both ends of the tensioning member, the spring 23 expands and thereby locks the shoelace in two places in the tensioning member, see Fig. 9.

Genom den nedre delens 24 utformning uppnås en väsentligt svagare låsning i de und- re hälen 11-21 än i de övre hålen 10-20.Due to the design of the lower part 24, a significantly weaker locking is achieved in the lower heels 11-21 than in the upper holes 10-20.

För att sedan justera längden på skosnöret trycker man ned enbart den övre delen 22, varvid man kan flytta hela spännorganet utmed skosnöret till lämpligt ställe.To then adjust the length of the shoelace, only the upper part 22 is pressed down, whereby the entire clamping member can be moved along the shoelace to a suitable place.
