Abstract

The chute is formed by a telescopic channel, which is extended to its full length as it is swung out.

Description

"sfzzo står' 1, Utfirandeexempel: Figur l. visar en som exempel vald uttöringsform av rutschbanan utfälld och sedd från sidan. "sfzzo stands' 1, Exemplary embodiment: Figure l. shows an exemplary form of drying of the slide unfolded and seen from the side.

Figur 2. visar skåpet i perspektiv fastsatt på plattform/balkong.Figure 2. shows the cabinet in perspective attached to the platform / balcony.

Figur 3. visar genomskäming av skåpet med utlösningsmekanism.Figure 3. shows a cross-section of the cabinet with a release mechanism.

Figur 4. visar genomskärning av ränna vid utdragsstoppen En som exempel vald utföringsform av uppfinningen visas på ﬁgur 1 med detaljer på ﬁgur 2-4. Enligt exemplet består anordningen av ett antal ränndelar (l), i exemplet 6 st, med stoppklackar (lb) som begränsar rännornas teleskopiska längd, en ledpunkt (la) i ena änden och med utfallbara ben (2) i den andra änden upphängd i vajrar (8) vilka är infästa i sin övre del i var sitt fjäderpaket (9).Figure 4. shows a cross-section of a gutter at the extraction stop. An exemplary embodiment of the invention is shown in Figure 1 with details in Figure 2-4. According to the example, the device consists of a number of gutter parts (1), in example 6 pcs, with stop lugs (1b) which limit the telescopic length of the gutters, a hinge point (1a) at one end and with extendable legs (2) at the other end suspended in wires (8) which are attached in their upper part in their respective spring package (9).

Ränndelens ledpunkter(la) är infasta i skåpets (3) nedre bärande konstruktion medan fjäderpaketen är fastsatta på dörrarnas (4) insida. Rutschbanans läge enligt ﬁgur 1 visar dess läge i obelastat utförande medan det streckade läget är vid belastning av en person. Figur 2 visar anordningen i ej aktiverat tillstånd med dörrarna (4) stängda, takets (5) falsar liggande över dörrarna med utlösningsmekanismen (6) intryckt. Ränndelama ligger an mot dörrarna (4) med en kraft alstrad med tjäderkraft (7), infastad på skåpets bärande konstruktion (3), varvid när utlösningsmekanismen (6), bestående av ett handtag försett rör med låsklack (6a), vid nödsituation vrids ca 180 grader så att låsklacken frigörs varvid utlösningsmekanismen dras ut och därefter trycks nedåt så att takets framkant (5) lyfts varvid takets ﬂäns tappar greppet om dörrarnas (4)övre kant och dörrarna trycks upp och ränndelari1a(l)faller framåt och nedåt.The joint points (1a) of the gutter part are fixed in the lower supporting structure of the cabinet (3) while the spring packages are attached to the inside of the doors (4). The position of the slide according to Figure 1 shows its position in unloaded design while the dashed position is under load of a person. Figure 2 shows the device in the inactivated state with the doors (4) closed, the roof (5) folds over the doors with the release mechanism (6) depressed. The gutter parts abut against the doors (4) with a force generated by capercaillie force (7), attached to the load-bearing structure (3) of the cabinet, whereby when the release mechanism (6), consisting of a handle provided with a tube with locking lug (6a), is turned approx. 180 degrees so that the locking lug is released whereby the release mechanism is pulled out and then pushed down so that the front edge (5) of the roof is lifted whereby the end of the roof ta ends the grip on the upper edge of the doors (4) and the doors are pushed up and gutter divider (1) falls forward and down.

Som hjälp och trygghet vid nedfarten ﬁnns ett rep (10) fastsatt i skåpets övre bärbalk som den nödställde kan använda för att sänka hastigheten under nedfärden.As an aid and safety on the descent, a rope (10) is attached to the upper support beam of the cabinet, which the person in need can use to reduce the speed during the descent.

Claims

520,887 Patent claims:

Device which in an emergency develops into a chute / slide between an upper plane down to a ground plane by activating a release mechanism, characterized in that the chute / slide (1) comprises a number of units, which are telescopically extendable and extendable relative to each other. a certain friction, and which in the upper plane are displaced relative to each other but which for reaching the ground plane are intended to be projected relative to each other, and that the chute / slide during its downward movement towards the ground plane oscillates so that the ictional resistance between units whereby the secured channel / slide is extended to its full length.

Device according to claim 1, characterized in that the units of the gutter / slide (1) in the latter's collapsed condition are housed in a cabinet (3), on the upper plane and thereby the gutter parts are protected against precipitation and dirt.

Device according to claim 1, characterized in that the chute / slide in its developed and unloaded condition has a smaller slope than when the chute / slide is loaded.

Device according to Claim 1, characterized in that the release mechanism (6) functions as a locking device in the inactivated state.

Device according to claim 1, characterized in that the device comprises a rope which provides controlled speed in the descent.
