Abstract

The present invention relates to a protection means in the case of collision for vehicles provided with forklifts, such as forklift trucks. The means is characterised in that it comprises a front shield (1) to which are secured two parallel fork tunnels or box girders (4) into which the forks are intended to be inserted, said fork tunnels/box girders (4) being provided with locking means (6, 7, 15) to lock the shield and fork tunnels to the forks when a load is raised thereon, and to release when the load has been placed on the ground or floor.

Ett dylikt päkörningsskydd är mycket effektivt och är lätt att av- och pámontera. Det kan lätt omställas mellan olika bredder, och användandet av detta gör det möjligt att även använda längre gaffelben. Man fär vid föreslagna spärrorgan en effektiv läsning vid pà gaffelbenen upplyft last. Vid behov kan skyddet kompletteras med belysning, reflexer mm.Such a point guard is very effective and is easy to remove and dismount. It can be easily adjusted between different widths, and the use of this makes it possible to use longer fork legs as well. With the proposed locking means, an effective reading is obtained when the load is lifted on the fork legs. If necessary, the protection can be supplemented with lighting, reflectors etc.

Ritningar: Uppfinningen än exemplifierad i bifogade ritningar, av vilka figur 1 visar pàkörningsskyddet, sett framifràn, figur 2 ett snitt A-A i figur l, och figur 3 skyddet, sett ovanifràn.Drawings: The invention is further exemplified in the accompanying drawings, of which Figure 1 shows the crash protection, seen from the front, Figure 2 a section A-A in Figure 1, and Figure 3 the protection, seen from above.

Utföringsexempel.Exemplary embodiments.

I figur 1 visas pákörningsskyddet, sett framifrån, med en central del, frontpláten (1), och tva i förhållande till denna vikbara delar (3), vilka bland annat har till uppgift att vikas undan vid påkörning. Den centrala delen (1) av skärmen bestár av flera plåtar (2) inbördes förskjut- och låsbara (se bultorganen (11)) i och för inställande av olika bredder. Sidodelarna (3) är försedda med yttre gummilister (10).Figure 1 shows the impact protection, seen from the front, with a central part, the front plate (1), and two foldable parts (3) in relation to it, which, among other things, have the task of folding away in the event of a collision. The central part (1) of the screen consists of several plates (2) mutually displaceable and lockable (see bolt means (11)) for adjusting different widths. The side parts (3) are provided with outer rubber strips (10).

Vid skärmen (frontplàten (1)) är fästade tva gaffeltunnlar (4) eller ládbalkar (se figur 3),i vilka fordonets gaffelben är inskjutbara. De är fästade vid en balk (5) medelst bult- organ eller liknande och är inställbara i sidled för anpass- ning till olika gaffelbenbredder. Balken är medelst bultorgan 503 915 (12) fäst vid skärmen (l).Attached to the screen (front plate (1)) are two fork tunnels (4) or load beams (see figure 3), into which the fork legs of the vehicle are slidable. They are attached to a beam (5) by means of bolt members or the like and are adjustable laterally for adaptation to different fork leg widths. The beam is fastened to the screen (1) by means of bolt means 503 915 (12).

Vid gaffeltunnlarna/ládbalkarna (4) är pà undersidan fästa spärrorgan (se figur 2), bestàende av en fjäderbalastad (9) länk (6) (fjädern fäst vid (14)), och ledande kring en vid gaffeltunneln fäst ledpunkt (13). Ytteränden för denna länk (6) nedtryckes när lasten pá gaffelbenen nedsättes pà marken varvid fjädern (9) tryckes ihop. Vid denna länks innerände är fäst en andra länk (7), uppbärande eller kopplad till en spärr (15). Vid intryckt ytterlänk (6) och fjäder (9) är spärrdonet ej läsande, med vid upplyft last trycket fjädern (9) ut länken F6) och spärrdonet (15) làser fast det in- skjutna gaffelbenet vid gaffeltunneln (4) och lasten är fastlàst vid gaffeltrucken eller -fordonet. När man önskar ställa ned lasten och därvid sätter ner denna pä marken/gol- vet lossas kopplingen till gaffeltrucken och denna kan köras loss. Lasten bestàr ofta av en lastpall med pàlastat gods, vilken kvarhàlles vid gaffeltunnlarna medelst olika stödor- gan. Hela anordningen kan upplyftas medelst lyftbyglar (16).At the fork tunnels / load beams (4) locking means are attached to the underside (see figure 2), consisting of a spring ballast (9) link (6) (the spring attached to (14)), and leading around a hinge point (13) attached to the fork tunnel. The outer end of this link (6) is depressed when the load on the fork legs is lowered to the ground, whereby the spring (9) is compressed. Attached to the inner end of this link is a second link (7), supporting or coupled to a catch (15). When the outer link (6) and spring (9) are depressed, the locking device is not legible, with the spring (9) pushing out the link F6) and the locking device (15) locks the inserted fork leg at the fork tunnel (4) and the load is locked at the forklift truck or vehicle. When you wish to lower the load and thereby place it on the ground / floor, the coupling to the forklift is loosened and this can be driven loose. The load often consists of a pallet with loaded goods, which is retained at the fork tunnels by means of various support members. The entire device can be lifted by means of lifting brackets (16).

Spärrdonet (15) utgöres av en làsrulle,ett rör med vulkat gummi, s.k. länkarmsrulle.The locking device (15) consists of a locking roller, a tube with vulcanized rubber, so-called link arm roller.

Skärmen med dess sidodelar (3) utgör ett gott skydd mot större skador vid påkörning och gör anordningen enligt uppfinningen flexibel som beskrivits ovan. Anordningen enligt uppfinningen kan varieras pà màngahanda sätt inom ramen för nedanstående patentkrav.The screen with its side parts (3) constitutes a good protection against major damage in the event of a collision and makes the device according to the invention flexible as described above. The device according to the invention can be varied in many ways within the scope of the following claims.
