Description
8ÜÜ7824~9 Detekteringsorganen innefattar åtminstone två don. avgivande och mottagande lämplig kontinuerlig akustisk eller elektromag- netisk strålning, t.ex. infrarött ljus, radarvågor eller ult- raljud, löpande mellan armarna. The detection means comprise at least two devices. emitting and receiving suitable continuous acoustic or electromagnetic radiation, e.g. infrared light, radar waves or ultrasound, running between the arms.
Donen styr fordonets framdrivningsorgan så, att ett avbrott i det första donets stråle tilldelar fordonet en lägre hastighet och att ett avbrott i det andra donets stråle får fordonet att stanna, om inte de båda avkännande organen har indikerat att ett pall-liknande föremål införts mellan armarna. Om t.ex. en människa står i vägen mellan armarna påverkas enbart ett eller inget av dessa avkännande organ. Fordonet stannar allt- sa.The means control the propulsion means of the vehicle so that an interruption in the beam of the first means imparts a lower speed to the vehicle and that an interruption in the beam of the second means causes the vehicle to stop, unless the two sensing means have indicated that a pallet-like object has been inserted between the arms. . If e.g. a human being standing in the way between the arms affects only one or none of these sensory organs. The vehicle stops everything.
En utföringsform av uppfinningen beskrives nedan under hänvis- ning till bifogade ritning, där Fig. 1 visar ett fordon sett uppifrån, och där Fig. 2 visar en detaljförstoring av den streckade ramen i fig. 1.An embodiment of the invention is described below with reference to the accompanying drawing, in which Fig. 1 shows a vehicle seen from above, and in which Fig. 2 shows a detailed enlargement of the dashed frame in Fig. 1.
Fordonets chassi har betecknats med siffran 1 och de lastbä- rande organen med siffran 2, vilka exempelvis utgöres av gaff- lar. Fordonet 1 är försett med bakåt utskjutande armar 3, som ' sträcker sig utanför de lastbärande organen 2. Varje arm bes- tår av en inre, närmast fordonet 1 belägen del 3 och en yttre del 4. Den nämnda yttre delen 4 är mot verkan av en fjäder- kraft teleskopiskt förskjutbar in i den inre delen 3. Avsik- ten med detta arrangemang komer att framgå av det följande, i samband med att anordningens verkningssätt beskrivs.The chassis of the vehicle has been designated by the number 1 and the load-bearing members by the number 2, which, for example, consist of forks. The vehicle 1 is provided with rearwardly projecting arms 3, which extend beyond the load-bearing members 2. Each arm consists of an inner part 3 closest to the vehicle 1 and an outer part 4. The said outer part 4 is against the action of a spring force telescopically displaceable into the inner part 3. The purpose of this arrangement will be apparent from the following, in connection with the operation of the device being described.
Den ena av nämnda armar 3 är, på den sida som vetter- mot den andra armen, försedd med åtminstone två strålningsavgivande don (sändare) 5, 7. Mitt emot nämnda strålningsavgivande don 5, 7 är på den andra armen anordnade strålningsmottagande don 6, 8. De senare donen kan även utgöras av reflektorer, som återsänder strålen till repektive sändare 5, 7, vilken då är kombinerad med en mottagare. soo7a24-9 Mellan sändare 5, 7 resp. mottagareö, 8 på varje arm är organ 9, 10 anordnade, vilka organ avkänner föremål i sin omedelbara närhet. De kan i enklaste fall bestå av sprötförsedda ström- brytare, men kan också utgöras av mer kvalificerade anordning- ar, såsom radarutrustninar.One of said arms 3 is, on the side facing the other arm, provided with at least two radiation-emitting devices (transmitters) 5, 7. Opposite said radiation-emitting devices 5, 7 are radiation-receiving devices 6, arranged on the other arm. The latter devices can also consist of reflectors, which return the beam to respective transmitters 5, 7, which are then combined with a receiver. soo7a24-9 Between transmitters 5, 7 resp. receiver island 8 on each arm are arranged means 9, 10, which means sense objects in their immediate vicinity. They can in the simplest case consist of switch-mounted switches, but can also consist of more qualified devices, such as radar equipment.
Det ovan beskrivna fordonet fungerar på följande sätt. När fordonet 1 backas mot en lastpall (icke visad), förs lastpal- len in mellan armarna 3, 4. Strålen mellan de ytterst belägna strålningsavgivande mottagande donen 5, 6 bryts då, varvid fordonets 1 hastighet minskas. Vid den fortsatta hacknings- rörelsen bringas lastpallen i kontakt med båda avkänningsorga- nen, som då indikerar att avsett föremål befinner sig mellan armarna3, 4, vilket medför att fordonet ej bringas att stanna när strålen mellan de inre strålningsavgivande och mottagande donen 7, 8 bryts. Ifall ett annat föremål eller en människa hamnar mellan armarna 3,4 under backningsrörelsen, bryts på sama sätt som ovan den yttre strålen, varvid fordonets has- tighet minskar. I detta fall påverkas emellertid ej båda avkännande organen 9, 10 samtidigt, eftersom avståndet mellan armarna är för stort, vilket medför att när den inre strålen bryts fordonet 1 bringas att stanna.The vehicle described above operates in the following manner. When the vehicle 1 is backed against a pallet (not shown), the pallet is inserted between the arms 3, 4. The beam between the outermost radiation-emitting receiving devices 5, 6 is then broken, whereby the speed of the vehicle 1 is reduced. During the continued chopping movement, the pallet is brought into contact with both sensing means, which then indicates that the intended object is located between the arms 3, 4, which means that the vehicle is not made to stop when the beam between the internal radiation emitting and receiving devices 7, 8 is broken. . If another object or person ends up between the arms 3,4 during the reversing movement, the outer beam is refracted in the same way as above, whereby the speed of the vehicle decreases. In this case, however, both sensing means 9, 10 are not affected at the same time, since the distance between the arms is too large, which means that when the inner beam is refracted, the vehicle 1 is caused to stop.
Skulle någon av armarna 3, 4 under backningsrörelsen_ stöta emot ett föremål, trycks den yttre armen 4 mot verkan av fjä- derkraften in i armen 3, varvid strömbrytare eller liknande don ombesörjer att fordonet 1 stannar. I Genom uppfinningen har således åstadkommits ett påbacknings- skydd, som på ett effektivt sätt förhindrar personskador eller' skador på föremål.Should any of the arms 3, 4 collide with an object during the reversing movement, the outer arm 4 is pressed against the action of the spring force into the arm 3, whereby switch or similar device ensures that the vehicle 1 stops. The invention has thus provided a back-up protection which effectively prevents personal injury or damage to objects.
