Fremgangsmåde og holder til bit-håndtering.Process and holder for bit handling.

Den foreliggende opfindelse omhandler en fremgangsmåde til isætning og udtagning af skmebits fra en bitholder, og en bitholder til gennemførelse af 5 fremgangsmåden.The present invention relates to a method for inserting and removing schmebits from a bit holder and a bit holder for carrying out the method.

Fra US 5.188.242 kendes en bitholder, der er udformet som en klods med et antal gennemgående huller, i hvilke en skruebit kan indsættes fra oversiden af bitholderen og tages ud fra undersiden. Bitholderen har en tykkelse på 5/8” -3/4”, 15,8 -19 mm. En skruebit har en længde på 25 mm, hvoraf soklen har en 10 længde på ca. 15 mm. Dersom en skruebit skal tages ud af bitholderen fra neden ved at soklen fastgøres i en skruemaskine eller andet værktøj, skal soklen rage 11 mm neden for bitholderens underside. Den resterende længde 25 + 11 - 14 mm er placeret i bitholderen. Med en tykkelse af bitholderen på 15,8 -19 mm bliver spidsen af skruebitten ikke synlig. Da en skruebit indsættes fra oven i 15 bitholderen med spidsen øverst og soklen nederst, skal den presses ned i bitholderen ved håndkraft, hvilket er besværligt og kræver arbejdshandsker eller andet udstyr, da spidsen har skarpe kanter. Endvidere skal skruebitten skydes et stykke ned i et hul i bitholderen, så oversiden af spidsen har en afstand på 1,8 -4 mm fra oversiden af bitholderen, hvilket kræver et hjælpeværktøj. Bitholderen 20 er fremstillet af et elastisk materiale, og huller har en lidt mindre diameter end en skruebit, hvorved bittene kan fastholdes i bitholderen.From US 5,188,242 there is known a bit holder which is designed as a block with a number of through holes in which a screw bit can be inserted from the top of the bit holder and taken out from the underside. The bit holder has a thickness of 5/8 ”-3/4”, 15.8 -19 mm. A screw bit has a length of 25 mm, of which the base has a length of approx. 15 mm. If a screw bit is to be removed from the bit holder from below by attaching the base to a screwdriver or other tool, the base must protrude 11 mm below the underside of the bit holder. The remaining length 25 + 11 - 14 mm is placed in the bit holder. With a thickness of the bit holder of 15.8 -19 mm, the tip of the screw bit will not be visible. Since a screw bit is inserted from the top into the bit holder with the tip at the top and the base at the bottom, it must be pressed down into the bit holder by hand, which is cumbersome and requires work gloves or other equipment as the tip has sharp edges. Furthermore, the screw bit must be pushed down a bit into a hole in the bit holder so that the top of the tip has a distance of 1.8 -4 mm from the top of the bit holder, which requires an auxiliary tool. The bit holder 20 is made of an elastic material and holes have a slightly smaller diameter than a screw bit, whereby the bits can be retained in the bit holder.

Det er en ulempe ved denne bitholder og andre kendte bitholdere, f.eks. i form af æsker, at bitten skiftes med fingrene fra holder eller æske til magnetbitholder eller omvendt, når man skifter til skruer med anderledes kærv. Det kræver to 25 hænder at tilvejebringe skiftet. Skiftet er besværligt og tidskrævende. Bittene er små og kan være vanskelige at holde fast i. Ofte ender bittene i lommen sammen med andre bit, hvor man så har problemet med at finde den rigtige bit næste gang, der skal skiftes.It is a disadvantage of this bit holder and other known bit holders, e.g. in the form of boxes that the bit is changed with the fingers from holder or box to magnetic bit holder or vice versa when changing to screws with different notches. It takes two 25 hands to provide the change. The shift is cumbersome and time consuming. The bits are small and can be difficult to hold. Often the bits end up in the pocket along with other bits, where you then have the problem of finding the right bit the next time you need to change.

Det er et formål med den foreliggende opfindelse at anvise en fremgangsmåde til 30 håndtering af skruebits fra en bitholder, ved hvilken de nævnte ulemper undgås.It is an object of the present invention to provide a method for handling screw bits from a bit holder, avoiding said drawbacks.

Dette opnås ved den i krav 1 angivne fremgangsmåde.This is achieved by the method of claim 1.

Krav 2 omhandler en fremgangsmåde til afsætning afen skruebit i et hul i en bitholder.Claim 2 relates to a method of depositing a screw bit into a hole in a bit holder.

DK 176345 B1 -2-DK 176345 B1 -2-

Krav 3 omhandler en bitholder til gennemførelse af fremgangsmåden ifølge opfindelsen.Claim 3 discloses a bit holder for carrying out the method according to the invention.

Krav 4 omhandler en udførelsesform for en bitholder ifølge opfindelsen.Claim 4 relates to an embodiment of a bit holder according to the invention.

5 Krav 5 omhandler et foretrukket materiale til fremstilling af en bitholder ifølge opfindelsen, og krav 6 omhandler midler til fastgørelse af en bitholder ifølge opfindelsen.Claim 5 relates to a preferred material for preparing a bit holder according to the invention, and claim 6 relates to means for attaching a bit holder according to the invention.

Opfindelsen skal forklares nærmere i det følgende under henvisning til tegningen, på hvilken 10 fig. 1 viser i fuld størrelse, i delvist snit og set fra siden, en holder til skruebits ifølge opfindelsen, fig. 2 viser i mindre målestok en holder til skruebits ifølge opfindelsen, fig. 3 viser en magnetbitholder, og fig. 4 viser en skruemaskine.The invention will be explained in more detail below with reference to the drawing, in which: FIG. 1 is a full-scale, partial sectional side view of a screw bit holder according to the invention; FIG. Fig. 2 shows on a smaller scale a screw bit holder according to the invention; 3 shows a magnetic bit holder and FIG. 4 shows a screwdriver.

15 Det særlige, man opnår ved opfindelsen, er at holde bittene 2 samlet, samt at en bit 2 kan skiftes uden, at man skal have fat i den med fingrene. Man kan beholde skruemaskinen i brugerhånden og tage holderen 1 i den anden hånd.The special thing that is achieved by the invention is to hold the bits 2 together and that a bit 2 can be changed without having to grasp it with your fingers. You can keep the screwdriver in the user's hand and take the holder 1 in the other hand.

Holderen 1 kan eventuelt også fastgøres til beklædning, bælte, arm med videre. Fastgørelsen kan eventuelt ske ved hjælp af clips, spænde, velcro eller lignende.The holder 1 can optionally also be attached to the clothing, belt, arm and so on. The attachment can optionally be made using clips, buckles, velcro or the like.

20 Det muliggør, at skiftet kan udføres med kun en hånd, nemlig hånden med skruemaskinen 4. Det kan være vigtigt, hvis man f.eks. har brug for den anden hånd til at holde fast med, ved f.eks. arbejde på en stige.20 It is possible that the change can be performed with only one hand, namely the hand with the screwdriver 4. It may be important if, for example, the need the other hand to hold on to, for example. work on a ladder.

Skiftet bliver hurtigt, og det er nemt at finde den rigtige bit, da spidsen 4 af bitten 2 er synlig.The shift becomes fast and it is easy to find the right bit as the tip 4 of the bit 2 is visible.

25 DK 176345 Bl -3-DK 176345 Bl -3-

Holderen 1 er udført af et elastisk materiale, der genvinder sin form og er slidstærkt.The holder 1 is made of an elastic material which regains its shape and is durable.

5 Holderen kan udføres af en elastomer som f.eks. PUR.The holder may be made of an elastomer, e.g. PUR.

I holderen 1 er der udført huller 1’ i en dimension, som kan holde bittene, ca. 6 mm. Bittene 2 anbringes med soklen 3 udad, så det er muligt at få fat i soklen med magnetbitholderen 6, og med spidsen 4 synlig indad.In the holder 1, holes 1 'are provided in a dimension which can hold the bits, approx. 6 mm. The bits 2 are positioned with the base 3 outwards, so that it is possible to grasp the base with the magnetic bit holder 6 and with the tip 4 visible inwards.

10 Holderen kan antage forskellige former afhængigt af, om den skal være i lommen, i bæltet, om den skal fastgøres til beklædning eller eventuelt til selve skruemaskinen 6 etc. Bittene fastholdes i holderen 1, fordi hullet har en mindre diameter end den enkelte bit 2, hvorved det elastiske materiale klemmer omkring bitten 2 og fastholder denne i holderen 1. Ved afsætning af bitten 2 i holderen 1 15 sættes bittens 2 spids 4 i hullet på holderen 1, og man lader skruemaskinen 5 rotere ganske lidt og presser bitten 2 ind i hullet. Når bitten 2 roterer, bliver friktionen mindre mellem bitten 2 og det elastiske materiale, og man kan let presse bitten 2 ind på plads i holderen 1, hvor den sidder fast, når rotationen stopper, tilstrækkelig fast til, at magnet- bitholderen kan frigøres fra bitten 2, som 20 så sidder tilbage i holderen 1.10 The holder can take different shapes depending on whether it should be in the pocket, in the belt, whether it should be attached to the cladding or possibly to the screwdriver 6, etc. The bits are retained in the holder 1 because the hole has a smaller diameter than the individual bit 2. whereby the elastic material clamps around the bit 2 and retains it in the holder 1. By depositing the bit 2 in the holder 1, the tip 4 of the bit 2 is inserted into the hole of the holder 1 and the screwdriver 5 is rotated quite a bit and the bit 2 is pressed into the the hole. As the bit 2 rotates, the friction decreases between the bit 2 and the elastic material, and the bit 2 can easily be pressed into place in the holder 1, where it is stuck when the rotation stops, sufficiently firmly for the magnetic bit holder to be released from the bit 2, which 20 then sits back in the holder 1.

Når bitten 2 skal frigøres fra holderen 1, sættes magnetbitholderen 6 igen på bitten 2, og man lader skmemaskinen 5 rotere ganske lidt. Når bitten 2 roterer, vil det elastiske materiale - sammen med et let træk - på grund af bittens 2 form automatisk trække bitten 2 fri af holderen 1, og bitten 2 sidder igen i 25 magnetbitholderen 6.When the bit 2 is to be released from the holder 1, the magnetic bit holder 6 is again put on the bit 2 and the sewing machine 5 is allowed to rotate quite a bit. As the bit 2 rotates, the resilient material - along with a slight pull - will automatically pull the bit 2 free from the holder 1, and the bit 2 again sits in the magnetic bit holder 6.

Holderen 1 kan udføres i en elastomersom f.eks. PUR. Den afbildede holder 1, fig, 1, er udført ved at fræse form og huller ud af en 15 m/m plade i materialet PUR. Ved eventuel produktion kan holderen sprøjtestøbes i samme materiale.The holder 1 can be made in an elastomer if e.g. PUR. The depicted holder 1, Fig. 1, is made by milling molds and holes out of a 15 m / m plate in the material PUR. In case of possible production, the holder can be injection molded in the same material.

Holderen er udviklet til at fungere sammen med bits 2 og magnetbitholdere 6, der 30 findes på markedet i dag.The holder is designed to work with bits 2 and magnetic bit holders 6, which 30 are on the market today.

Holderen kan antage mange alternative former og udstyres med clips, spænde eller andet, der muliggør, at den kan fastgøres til beklædning, bælte m.v. Der eventuelt præges tekst på holderen såsom størrelse på bit m.v.The holder can take many alternative forms and is equipped with clips, buckles or other means that allow it to be fastened to clothing, belt etc. Optionally, text is embossed on the holder such as size of bits etc.
