Den foreliggende frembringelse angår et redskab såsom en spade, en greb eller andet, som omfatter et rørformigt skaft, der for enden er forsynet med et håndtag. Opfindelsen angår endvidere et sådant håndtag.The present invention relates to a tool such as a spade, a grip or other, which comprises a tubular shaft end bearing a handle. The invention further relates to such a handle.

5 Det er almindeligt at forsyne et sådant håndtag med en rørformet forbindelsesdel, som ved montering optager skaftet, hvorefter en skrue, stift eller lignende kan føres gennem den rørformede monteringsdel og skaftet for med sikkerhed at holde håndtaget fast på skaftet.It is common to provide such a handle with a tubular connecting member which, upon mounting, receives the shaft, after which a screw, pin or the like may be passed through the tubular mounting member and shaft to securely hold the handle to the shaft.

10 Det nye ved frembringelsen er, at håndtaget omfatter en tap, der med en prespasning passer ind i det rørformige skaft. Prespasningen er fortrinsvis så hård, at der ikke behøves andre midler til at sikre håndtagets fastgøring på skaftet. Dette kan have en ikke-cirkulær 15 profil for derved at forhindre, at håndtaget drejes i forhold til skaftet.10 The new feature of the invention is that the handle comprises a pin which fits into the tubular shaft with a press fit. The pressing fit is preferably so hard that no other means is required to secure the handle to the shaft. This may have a non-circular profile to thereby prevent the handle from rotating relative to the shaft.

Tappen af håndtaget ifølge frembringelsen omfatter fortrinsvis recesser for at give tappen en passende elasticitet på tværs af sin længderetning eller ind-20 føringsretning ved montering i skaftet. Recesserne er fortrinsvis langsgående i forhold til tappens længdeakse og spalteformede.The pin of the handle according to the invention preferably comprises recesses to provide the pin with a suitable elasticity across its longitudinal or insertion direction when mounted in the shaft. Preferably, the recesses are longitudinal relative to the longitudinal axis and slot-shaped of the pin.

I en udførelsesform, hvor håndtaget omfatter en gribedel, der strækker sig på tværs af skaftets længde-25 retning, forløber recesserne fra tappens overflade i en retning på tværs af gribedelen til en central massiv del af tappen. Recesserne er endvidere fortrinsvis afbrudt af mindst ét massivt parti af tappen. Herved opnås udover en nødvendig fleksibilitet af tappen også en 30 krævet stabilitet.In one embodiment, wherein the handle comprises a gripping member extending across the longitudinal direction of the shaft, the recesses extend from the surface of the pin in a direction across the gripping portion to a central solid portion of the pin. Furthermore, the recesses are preferably interrupted by at least one solid portion of the pin. In addition to the necessary flexibility of the pin, the required stability is also obtained.

Frembringelsen vil i det følgende blive forklaret nærmere ved hjælp af et udførelseseksempel under henvisning til tegningen, på hvilken fig. 1 viser et perspektivbillede af en spade 35 ifølge opfindelsen, 2 2DK 94 00347 U3 fig. 2 og 3 viser selve håndtaget af spaden set henholdsvis forfra og fra siden og fig. 4 et snit langs linien IV-IV i fig. 2 og 3.The invention will now be explained in more detail by way of an exemplary embodiment with reference to the drawing, in which FIG. 1 shows a perspective view of a shovel 35 according to the invention, 2DK 94 00347 U3 FIG. 2 and 3 show the handle of the spade itself seen from the front and the side respectively, and fig. 4 is a section along line IV-IV of FIG. 2 and 3.

Den i fig. 1 viste spade omfatter et blad 1, et 5 skaft 2 af stålrør og et håndtag 3, der har en tap 4, som er presset ned i skaftet 2, og en gribedel 8.The FIG. 1, the blade 1 comprises a blade 1, a steel shaft 2 shaft 2 and a handle 3 having a pin 4 pressed down into the shaft 2 and a gripping member 8.

Håndtaget 3, som ses nærmere i fig. 2 og 3 er eksempelvis støbt af polypropylen og tappen 4 er med henblik på en sikker fastholdelse i skaftet 2 dels 10 fremstillet med et passende overmål i forhold til hullet i skaftet 2, dels udformet med recesser 5 for at tilvejebringe en passende elasticitet.The handle 3, as seen in FIG. 2 and 3, for example, are molded from polypropylene and the pin 4 is designed for secure retention in the shaft 2 partly 10 with a suitable oversize over the hole in the shaft 2 and partly formed with recesses 5 to provide a suitable elasticity.

Recesserne 5 er eksempelvis, som det fremgår af tegningen, udformet som langsgående spalter, der fra 15 tappen 4's overflade strækker sig i det væsentlige parallelt ind i tappen til et massivt centralt område 6 af tappen. Recesserne 5 er, som dét ligeledes fremgår af tegningen, afbrudt af skiveformede massive områder 7.The recesses 5 are, for example, as shown in the drawing, formed as longitudinal slots extending from the surface of the pin 4 substantially parallel to the pin to a solid central region 6 of the pin. The recesses 5, as also shown in the drawing, are interrupted by disc-shaped solid areas 7.

20 Som det fremgår af fig. 4 er tappen 4 i den viste udførelsesform indrettet til et skaft 2 med et ægformet profil, hvilket blandt andet har den fordel, at håndtaget ikke kan dreje i forhold til skaftet. Frembringelsen er dog ikke begrænset til nogen bestemt profil af 25 skaftet, som for den sags skyld kunne være rundt.20 As can be seen from FIG. 4, the pin 4 in the illustrated embodiment is arranged for a shaft 2 with an egg-shaped profile, which has the advantage, inter alia, that the handle cannot rotate with respect to the shaft. However, the production is not limited to any particular profile of the shaft, which for that matter could be around.

For at sikre at tappen 4 sidder i spænd i skaftet, er den fremstillet med et overmål i forhold til det hul i skaftet, hvori den skal indføres. Overmålet ligger i området 1,0-5,0%.In order to ensure that the pin 4 fits tightly in the shaft, it is made with an oversize relative to the hole in the shaft into which it is to be inserted. The target is in the range of 1.0-5.0%.
