Description

15 20 25 30 35 457 939 Uppfinningen kommer nedan att närmare beskrivas i anslutning till den bifogade ritningen, som schematiskt visar en lämp- lig utföringsform av uppfinningen, varvid fig. l visar en bàgság, försedd med en fingerskyddsanordning enligt upp- finningen, fig. 2 visar en förstorad sidovy av den främre bàgänden jämte den därvid fästade skyddsanordningen, och fig. 3 visar sektion längs linjen A-A i fig. 2. The invention will be described in more detail below in connection with the accompanying drawing, which schematically shows a suitable embodiment of the invention, Fig. 1 showing a bag saw, provided with a finger protection device according to the invention, fig. Fig. 2 shows an enlarged side view of the front rear end together with the protective device attached thereto, and Fig. 3 shows a section along the line AA in Fig. 2.

Den i fig. 1 visade sàgen innefattar en sàgbàge 1, som ut- göres av ett metallrör, som i bada ändarna är utformat med ett förträngt plattparti. Sàgbagen 1 är i ena änden försedd med en därvid rörligt nitad spännarm 2. vid spännarmen 2 är en bakre fästbygel 3 rörligt nitad och vid sàgbàgens l andra ände är en främre fästbygel 4 rörligt nitad. Byglarna 3 och 4 är i sin mot sàgbladet 5 vända ände försedda med nitar 6 för sägbladets 5 infästning. Den främre bygeln 4 har vid sin fran sàgbladet 5 vända ände förträngts intill ett s pel bygel- ändarna emellan, svarande mot tjockleken av ságbàgens 1 till- plattade ändavslutníng, under det att den bakre bygeln 3 pa motsvarande sätt förträngts intill ett spel bygeländarna emellan, som svarar mot tjockleken av den vid den bakre bag- änden med denna rörligt fastnitade och likaledes tillplattade ändavslutningen hos spännarmen 2. Nitningen mellan främre bygel och bàgände respektive mellan bakre bygel och spännarm 2 är utförd pá sedvanligt sätt.The saw shown in Fig. 1 comprises a saw bow 1, which is formed by a metal tube, which at both ends is formed with a narrowed plate portion. The saw bag 1 is provided at one end with a clamping arm 2 movable therewith. The brackets 3 and 4 are provided at their end facing the saw blade 5 with rivets 6 for the attachment of the saw blade 5. The front bracket 4 has been narrowed at its end facing away from the saw blade 5 next to a clearance between the bracket ends, corresponding to the thickness of the flattened end end of the saw frame 1, while the rear bracket 3 is correspondingly narrowed next to a clearance between the bracket ends. which corresponds to the thickness of the end end of the clamping arm 2 which is movably fastened at the rear rear end and likewise flattened.

Enligt uppfinningen är en fingerskyddsanordning 7 anbragt vid sàgbàgens 1 bakre greppände. Anordningen 7 innefattar en fingerskyddsbygel 8 och en greppdel 9 utformade i ett stycke med varandra lämpligen i en sluten parallell trapetsformad profil sàsom visas i fig. 1. Greppdelen 9 är i sektion U- formad och innefattar tvâ sidostycken 10 och 11 sà dimensio- nerade att de berör mer än hälften av omkretsen av bàgens 1 tvärsektion utan att helt omsluta denna.According to the invention, a finger protection device 7 is arranged at the rear gripping end of the saw frame 1. The device 7 comprises a finger protection bracket 8 and a grip part 9 formed in one piece with each other suitably in a closed parallel trapezoidal profile as shown in Fig. 1. The grip part 9 is in section U-shaped and comprises two side pieces 10 and 11 so dimensioned that they touch more than half the circumference of the cross section of the trunk without completely enclosing it.

Anordningen 7 är sàdan att sidostyckena 10, ll fjädrande berör bágen 1 och skall dragas sá làngt bakàt att de skjuter in i spännarmens 2 mot bàgen l vända konkava del, varigenom de vid stöt av 10 15 20 25 30 35 457 939 fingerskyddsbygeln 8 mot det vedstycke 12, vari sàgning sker, pressas hàrdare mot bàgen 1. För att ytterligare förhindra att fingerskyddsanordningen 7 vrids àt sidan vid en sàdan stöt_är den nedre horisontella delen av fingerskyddsbygeln 8 försedd med tva nedátriktade utspràng 13, 14, som gär ner pà var sin sida av sàgbladet 5 eller fästbygeln 3.The device 7 is such that the side pieces 10, 11 resiliently touch the frame 1 and must be pulled so far backwards that they project into the concave part of the clamping arm 2 facing the frame 1, whereby they, on impact of the finger guard bar 8 against it, wood piece 12, in which sawing takes place, is pressed harder against the bow 1. To further prevent the finger protection device 7 from being turned to the side at such a shock, the lower horizontal part of the finger protection bracket 8 is provided with two downwardly directed projections 13, 14, which go down on each side of the saw blade 5 or the mounting bracket 3.

En fingerskyddsanordning enligt uppfinningen kan med fördel anbringas pà sàgbágar med varierande sektion. Den kan an- bringas sedan bàgen i övrigt är färdig och även lätt utbytas om den blivit skadad.A finger protection device according to the invention can advantageously be mounted on saw hoops with varying sections. It can be applied after the frame is otherwise finished and can also be easily replaced if it has been damaged.
