Abstract

Lift cage provided with a guard extending downwards for preventing persons to fall down into the lift shaft below the lift cage at emergency evacuation, the guard being articulated to the bottom of the lift cage immediately below the floor at the lift cage door. Furthermore the guard is controlled by a roller at the lower edge of the guard. This roller runs in a U-shaped guide that is applied to a lateral wall of the shaft. The guide runs vertically over the entirely height of the lift shaft but in the lower end were the guide bends inward and transcends into a horizontal section. In this way the guard will be maintained vertical but when it comes close to its most lowered position where the guard is swung in below the bottom of the lift cage. The lift cage guard can in this way simply and efficiently be used also at later installations of lifts were there its no pit below the lift cage in its bottom position. <IMAGE>

Description

525 919 n I | o . . av o ; n u . | v c n a .u 2 vid kanten men denna kan placeras mellan bärande balkar i hiss- botten. Styrningen kan lämpligen innefatta ett kullager som med en bult är förbundet med skärmen och en vid schaktets vägg fäst styrskena som omsluter kullagret. Skenan är nederänden mer eller mindre kvartscirkelformad böjd inåt. 525 919 n I | o. . av o; now . | v c n a .u 2 at the edge but this can be placed between load-bearing beams in the elevator floor. The guide may suitably comprise a ball bearing which is connected to the screen by a bolt and a guide rail which is attached to the wall of the shaft which encloses the ball bearing. The rail is the lower end more or less quarter circle-shaped bent inwards.

Om så skulle önskas för att öka säkerheten ytterligare kan man tänka sig att skärmen på den ovanstående styrningen motsatta sidan över hela sin höjd löper i en ytterligare styrning som bara sträcker sig ner över de övre våningarna eftersom skärmen inte behövs i bottenvåningen. Denna styrning har ingen insvängnings- funktion.If desired to further increase safety, it is conceivable that the screen on the above guide opposite side over its entire height runs in an additional guide which only extends down over the upper floors as the screen is not needed in the ground floor. This control has no swing-in function.

Skärmanordningen enligt uppfinningen blir mycket tillför- litlig och driftsäker genom att den är fullständigt mekanisk och skärmen är effektivt tvångsstyrd. Vidare är anordningen mycket lättkontrollerad eftersom det räcker med att titta och ta i den för att avgöra om den är funktionsduglig eller ej. Ingen elek- tronik krävs för att registrera de olika lägena för skärmen. An- ordningen är stark och tar samtidigt extremt lite plats i botten- läget. Skulle styrningen av ena eller andra skälet bortfalla så kommer skärmen när hissen näras sig botten att deformeras mer eller mindre samt förorsaka att hissen stannar, vilket då endast kan ske med hissen i närheten av dess bottenläge varvid hissens av andra skäl föreliggande säkerhetssystem aktiveras i detta extremt osannolika olyckstillfälle.The screen device according to the invention becomes very reliable and reliable in that it is completely mechanical and the screen is effectively forcibly controlled. Furthermore, the device is very easy to control because it is enough to look and touch it to determine if it is functional or not. No electronics are required to register the various positions of the screen. The device is strong and at the same time takes up extremely little space in the bottom position. Should the control for one reason or another be lost, the screen when the lift approaches the bottom will be more or less deformed and cause the lift to stop, which can then only happen with the lift near its bottom position whereby the lift's other safety system is activated in this extreme unlikely accident.

Ytterligare fördelar och kännetecken på uppfinningen framgår närmare av nedanstående beskrivning av ett på bifogad ritning visat utföringsexempel samt av patentkraven. I fig_l Visas ett hisschakt med en tillhörande hisskorg sedd från sidan med en schaktvägg upptagen, fig 2 visar en detalj från fig 1, fig 3 visar hisschaktet i fig 1 med korgen nedsänkt något ytterligare, fig 4 en detalj från fig 3 i större skala, fig 5 hisschaktet sett från sidan med hisskorgen i sitt nedersta läge och fig 6 en för- storing av en detalj i fig 5.Further advantages and features of the invention appear in more detail from the following description of an exemplary embodiment shown in the accompanying drawing and from the claims. Fig. 1 shows an elevator shaft with an associated elevator car seen from the side with a shaft wall occupied, Fig. 2 shows a detail from Fig. 1, Fig. 3 shows the elevator shaft in Fig. 1 with the basket lowered slightly further, Fig. 4 a detail from Fig. 3 on a larger scale, Fig. 5 is a side view of the elevator shaft with the elevator car in its lowest position and Fig. 6 is an enlargement of a detail in Fig. 5.

Den på ritningarna visade hissen innefattar ett schakt 1 i vilket en hisskorg 2 är vertikalt rörlig. Från hisskorgen sträc- | | n a a n n Q ø a | n n a a | I o u o - n n n 3 ker sig vertikalt nedåt en skärm 3 på den sida där dörrarna är anbragta. Skärmen 3 är i sin överände via ett pianogångjärn ledad vid nederkanten av hisskorgens botten. I nederänden är skärmen försedd med en i sidled utskjutande bult på vilken ett kullager är anordnat, vilket kullager löper inuti en styrskena 4 som löper vertikalt i schaktet utom längst ned i närheten av schaktets botten där styrskenan svänger av in mot schaktets mitt i en mjuk båge som sedan avslutas med ett horisontellt avsnitt nära hisschaktes botten.The elevator shown in the drawings comprises a shaft 1 in which an elevator car 2 is vertically movable. From the elevator car stretch- | | n a a n n Q ø a | n n a a | I o u o - n n n 3 a screen 3 moves vertically downwards on the side where the doors are located. The screen 3 is at its upper end via a piano hinge articulated at the lower edge of the bottom of the elevator car. At the lower end, the screen is provided with a laterally projecting bolt on which a ball bearing is arranged, which ball bearing runs inside a guide rail 4 which runs vertically in the shaft except at the bottom near the bottom of the shaft where the guide rail swings towards the shaft in the middle of a soft arc which then ends with a horizontal section near the bottom of the elevator shaft.

Skärmen fungerar på så sätt att den av styrningen hålls vertikal utom när hissen närmar sig sitt bottenläge då den nedre styrningen (kullagret) följer styrskenan såsom visas i fig 3 och 4. När till sist korgen når sitt bottenläge så ligger korgskärmen platt under korgen. När hisskorgen åter rör sig uppåt är rörelsen den motsattaThe screen works in such a way that it is kept vertical by the guide except when the lift is approaching its bottom position when the lower guide (ball bearing) follows the guide rail as shown in Figs. 3 and 4. When the basket finally reaches its bottom position, the basket screen lies flat under the basket. When the elevator car moves upwards again, the movement is the opposite
