Abstract

The coupling (1) is intended for securing a handle (5) to a tool (8) e.g. a broom or rake. It comprises a hollow element (2) secured to or part of the tool and provided with an internal taper screw thread (4), to grip the end of the handle. A clamp is provided for the end of the handle, e.g. circumferentially spaced axially projecting resilient lips (10). - These clamps are radially inwardly pressed by a screw bush (3) around the end of the handle, with an internal screw thread (13) fitting on external thread (11) on the element (2). The bush pref. has an internal cone (14) to engage the ends (9) of the lips.

Description

i DK 168618 B1in DK 168618 B1

Opfindelsen angår en kobling for fastgørelse af et håndtag til et værktøj som beskrevet i indledningen til krav 1, med andre ord, mere nøjagtigt en kobling til let og 5 effektivt at fastgøre et håndtag til et værktøj, hvorved dette værktøj let kan fjernes, f.eks. for at fastgøre håndtaget til et andet værktøj. Værktøjet kan være af enhver art, f.eks. en børste, en skraber, etc.The invention relates to a coupling for attaching a handle to a tool as described in the preamble of claim 1, in other words, more accurately a coupling to easily and effectively attach a handle to a tool whereby this tool can be easily removed, f. eg. to attach the handle to another tool. The tool can be of any kind, e.g. a brush, a scraper, etc.

Koblinger, ved hjælp af hvilke man er i stand til hurtig 10 at fastgøre et håndtag til et værktøj, er kendt. Disse kendte koblinger har imidlertid den ulempe, at de kun er forsynet med et enkelt spændeorgan, der kan spændes således at samlingen, der opnås med disse kendte koblinger, ikke er sikker. En kobling som beskrevet i indledningen 15 til krav 1 kendes fra DE-U-8524050.Couplings by which one is able to quickly attach a handle to a tool are known. However, these known couplings have the disadvantage that they are only provided with a single clamping means which can be tightened so that the joint obtained with these known couplings is not secure. A coupling as described in the preamble 15 of claim 1 is known from DE-U-8524050.

Opfindelsen har til formål at anvise en kobling, der ikke har disse ulemper, hvor der i koblingen på den ene side er brugt et fastgørelsesorgan og på den anden side yderligere fastgørelsesorganer, med henblik på at opnå en dobbelt 20 kobling, der giver et større niveau af effektivitet og sikkerhed.The invention has for its object to provide a coupling which does not have these drawbacks, in which a fastener is used in the coupling on the one hand and on the other hand additional fastening means, in order to obtain a double coupling which gives a higher level of efficiency and safety.

Hed dette formål foreslår opfindelsen en kobling som angivet i den kendetegnende del af krav 1.For this purpose, the invention proposes a coupling as set forth in the characterizing portion of claim 1.

Egenskaberne og fordelene ved koblingen ifølge opfindelsen 25 vil fremgå klart af den følgende detaljerede beskrivelse af en foretrukken udførelsesform, der alene beskriver et eksempel uden at tilsigte en begrænsning, under henvisning til tegningen, hvor fig. i viser koblingen i dens fraskruede tilstand, 30 fig. 2 viser et tværsnit langs linie 11-11 i fig. 1, og fig. 3 viser koblingen i samlet tilstand.The characteristics and advantages of the coupling according to the invention 25 will become clear from the following detailed description of a preferred embodiment, which describes only an example without aiming at a limitation, with reference to the drawing, in which fig. 1 shows the coupling in its unscrewed state, FIG. 2 shows a cross section along line 11-11 of FIG. 1, and FIG. 3 shows the coupling in overall condition.

Som vist i figurerne består koblingen 1 primært af et første hult organ 2 og af et andet organ 3 i form af en DK 168618 B1 2 gevind-bøsning. Nævnte første organ 2 er i det væsentlige cylindrisk og er indvendig forsynet med fastgøringsorganer såsom en fort ånding eller et gevind til at modtage et 5 håndtag 5, der enten skrues ind i nævnte første organ 2 eller presses deri, alt efter udførelsesformen. Fortan-dingens middeldiameter er fortrinsvis gradvis formindsket nedefter.As shown in the figures, the coupling 1 consists primarily of a first hollow member 2 and of a second member 3 in the form of a DK 168618 B1 2 threaded bush. Said first member 2 is substantially cylindrical and is provided internally with fasteners such as a fastening or thread for receiving a handle 5 which is either screwed into said first member 2 or pressed therein, depending on the embodiment. The mean diameter of the tooth is preferably gradually decreased downward.

I den nedre ende 6 er nævnte første organ 2 fastgjort til 10 værktøjet eller udgør en del af dette. I den viste udførelsesform er enden 6 i indgreb med et hul 7 i et børste-legeme 8, og er f.eks. limet og/eller skruet deri, f.eks. ved hjælp af kroge eller tilsvarende organer.At the lower end 6, said first member 2 is attached to or forms part of the tool. In the illustrated embodiment, the end 6 engages a hole 7 in a brush body 8, and is e.g. glued and / or screwed therein, e.g. using hooks or similar organs.

Ved sin anden ende 9 er nævnte første organ 2 forsynet med 15 spændeorganer, der kan tilspændes, og som består af ra dialt elastisk bøjelige, men aksialt rettede små tunger 10.At its other end 9, said first member 2 is provided with 15 retractable clamping members, which consist of radially elastically flexible but axially directed small tongues 10.

På ydersiden er nævnte første organ 2 forsynet med gevind 11.On the outside, said first member 2 is provided with thread 11.

20 Det nævnte andet organ 3 har i det væsentlige form som en gevindbøsning forsynet med en aksial udboring 12 på en sådan måde, at dette organ passer til håndtaget 5 og til det første organ 2. Nævnte andet organ 3 er forsynet med indvendig gevind 13, der kan komme i indgreb med det ud-25 vendige gevind 11 på nævnte første organ 2 samt med en konisk del 14, der kan komme i indgreb med nævnte elasti ske tunger 10. Funktionen af koblingen vises klart i fig.Said second member 3 is essentially in the form of a threaded bushing provided with an axial bore 12 in such a way that this member fits the handle 5 and the first member 2. Said second member 3 is provided with internal thread 13, which may engage the external thread 11 of said first member 2 as well as a tapered portion 14 which may engage said elastic tongues 10. The function of the coupling is clearly shown in FIG.

1 og 3 og består i, at håndtaget 5 fastgøres i nævnte første organ 2 ved at trykke dets ende ind i fortandingen 30 4, og/eller skrue den deri, og derefter skubbe det andet organ 3 over håndtaget 5 og skrue det på nævnte første organ 2. Under påskruningen strammes tungerne 10 ved hjælp af den koniske del 14 omkring håndtaget 5, hvorved der opnås en dobbelt samling, der giver større effektivitet 3 DK 168618 B1 og sikkerhed.1 and 3 and consists in attaching the handle 5 to said first member 2 by pressing its end into the tooth 30 4, and / or screwing it therein, and then pushing the second member 3 over the handle 5 and screwing it on said first one. During the fastening, the tongues 10 are tightened by means of the tapered portion 14 around the handle 5, thereby obtaining a double joint for greater efficiency and safety.

Som det fremgår er denne opfindelse ikke begrænset til det viste eksempel, som vist i de givne tegninger, men en 5 sådan kobling og de forskellige dele af denne kan udføres i forskellig form og dimension uden at gå udenfor opfindelsens rammer.As can be seen, this invention is not limited to the example shown, as shown in the drawings, but such a coupling and the various parts thereof may be carried out in various shapes and dimensions without departing from the scope of the invention.
