Opfindelsen angår en afskærmningsanordning ved indgangen til en bygning, især en bygning med høj besøgsfrekvens såsom et varehus eller lignende. Til beskyttelse mod træk og afkøling er indgange af den foreliggende art i alminde-5 lighed forsynet med et såkaldt vindfang bestående af en yderdør, en mellemliggende passage og en inderdør. Dørene er sædvanligvis udført som automatisk arbejdende skydedøre og påvirkes for åbning, når en person passerer en føler i en passende anordning.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a screening device at the entrance to a building, in particular a high-frequency building such as a department store or the like. For protection against draft and cooling, inputs of the present kind are generally provided with a so-called porthole consisting of an outer door, an intermediate passage and an inner door. The doors are usually designed as automatic sliding doors and are actuated to open when a person passes a sensor in a suitable device.

10 Uisse problemer eksisterer ved disse vindfang. Hvis afstanden mellem yder- og inderdøren er for kort, må den passerende af og til vente, inden inderdøren åbnes. Endvidere opstår der forøget påvirkning af træk og kulde ved korte vindfang. På den anden side er vindfang pladskræ-15 vende og optager dyr gulvflade i lokalerne. Selv ved tilstrækkeligt store vindfang kan imidlertid besværlige problemer i form af træk og kulde optræde ved høj besøgsfrekvens.10 There are many problems with these gaps. If the distance between the exterior and the interior door is too short, it must occasionally pass before opening the interior door. In addition, there is an increased effect of draft and cold at short windfalls. On the other hand, the porch is bulky and takes up expensive floor space in the premises. However, even with sufficiently large wind gusts, troublesome problems in the form of traits and cold can occur at high frequency of visits.

Det er formålet med opfindelsen ved en med normalt vind-20 fang udrustet indgang at eliminere de ovenfor nævnte problemer. Dette er af særlig betydning for personale, som under arbejdstiden må opholde sig i nærheden af bygningens indgang, f.eks. personale, som arbejder ved kasserne i varehuse.The object of the invention is to eliminate the above-mentioned problems by means of a normally wind-blown input. This is of particular importance for personnel who must stay near the entrance of the building during working hours, e.g. staff working at the cash registers in department stores.

25 Dette formål opnås ifølge opfindelsen ved hjælp af en afskærmningsanordning ifølge de i det følgende anførte patentkrav. Denne afskærmningsanordning har som virkning, at den tilvejebringer et svagt undertryk uden for det normale vindfang, hvorved generende indstrømning af koldluft 30 i lokalerne undgås.This object is achieved according to the invention by means of a shielding device according to the following claims. This shielding device has the effect of providing a slight underpressure outside the normal windscreen, thereby avoiding annoying cold air flow 30 into the premises.

Udførelseseksempler på opfindelsen vil nu blive nærmere forklaret under henvisning til tegningen, på hvilkenEmbodiments of the invention will now be explained in more detail with reference to the drawing, in which

2 fig. 1 viser afskærmningsanordningen ifølge opfindelsen i perspektiv, fig. 2-6 viser forskellige indstillinger af de i anordningen indgående skærmvægge.2 FIG. 1 is a perspective view of the shielding device according to the invention; FIG. 2-6 show various settings of the screen walls included in the device.

5 En af mange mennesker besøgt bygning med ydervæggen 1 har en indgang 2 forsynet med et normalt, ikke nærmere vist vindfang, hvis ydre døre i form af to modstående skydedøre er betegnet 3,3. Disse døre er anordnet til på konventionel måde at åbne automatisk ved passage.5 One of many people visited the building with the outer wall 1 has an entrance 2 provided with a normal, not shown windscreen, whose outer doors in the form of two opposite sliding doors are designated 3.3. These doors are arranged to open automatically in the conventional manner upon passage.

10 Uden for indgangen 2 og midt for denne er der i passende afstand anordnet et vægparti 7, som nærmest har form som en trekantet søjle. På hver side af dette vægparti 7 er der lejret to skærmvægge 4,4 for svingning omkring respektive vertikale akser X-X. Skærmvæggene har rektangulær 15 form med en første vertikal kant 5 og en anden vertikal kant 6. Skærmvæggenes svingningsakse er beliggende således, at væggens anden vertikale kant 6 næsten følger en tilsvarende krummet sideflade 8 af vægpartiet 7, når skærmvæggen svinges omkring sin akse X-X. Som det fremgår af fig. 1, er 20 svingningsaksen X-X forskudt fra skærmvæggens midte mod dens anden vertikale kant 6, så at det af skærmvæggens parti mellem svingningsaksen og kanten 6 gennemfejede område holdes inden for begrænsede dimensioner svarende til en rimelig dybde af vægpartiet 7 vinkelret mod bygningens 25 væg.10 Outside of the entrance 2 and in the middle of it there is arranged at a suitable distance a wall portion 7 which is almost like a triangular column. On each side of this wall portion 7, two screen walls 4.4 are mounted for pivoting about respective vertical axes X-X. The screen walls are rectangular in shape with a first vertical edge 5 and a second vertical edge 6. The axis of oscillation of the screen walls is such that the second vertical edge 6 of the wall almost follows a correspondingly curved side surface 8 of the wall portion 7 as the screen wall is pivoted about its axis X-X. As shown in FIG. 1, the oscillation axis X-X is offset from the center of the screen wall towards its second vertical edge 6 so that the area swept by the screen wall between the oscillation axis and the edge 6 is kept within limited dimensions corresponding to a reasonable depth of the wall portion 7 perpendicular to the wall of the building 25.

Skærmvæggen kan indtage to endestillinger, nemlig en skråt- stillet stilling, i hvilken dens første vertikale kant ligger an mod ydervæggen 1, mens dens anden vertikale kant 6 befinder sig ved den ydre sidekant af den krumme side-30 flade 8 af vægpartiet 7, og en anden endestilling, i hvilken skærmvæggen strækker sig parallelt med bygningens ydervæg 1. Skærmvæggen når med sin underkant ned til en 3The screen wall may take two end positions, namely, an inclined position in which its first vertical edge abuts the outer wall 1, while its second vertical edge 6 is at the outer side edge of the curved side surface 8 of the wall portion 7, and another end position in which the screen wall extends parallel to the outer wall of the building 1. The screen wall reaches its lower edge to a 3

praktisk passende afstand fra fortovet forbi indgangen 2 og med sin overkant op til overdelen af vægpartiet 7, hvor skærmvæggen møder en ikke vist tagkonstruktion, som strækker sig mellem vægpartiet 7 og bygningens ydervæg 1.practically appropriate distance from the sidewalk past the entrance 2 and with its upper edge up to the upper part of the wall portion 7, where the screen wall meets a roof structure not shown extending between the wall portion 7 and the outer wall 1 of the building.

5 Denne tagkonstruktion kan have varierende udførsel og f.eks. danne et trekantet tagparti med sin basis over indgangen 2 og sin spids ved vægpartiet 7, eller have anden udførelse. Passende er det i hvert fald, at skærmvæggen i sin skråtstillede endestilling slutter sig med 10 sin overkant til tagpartiet af nedenfor anførte grunde.This roof structure may have varying designs and e.g. forming a triangular roof portion with its base above the entrance 2 and its tip at the wall portion 7, or having a different design. Suitably, in any case, the screen wall in its inclined end position joins with its upper edge to the roof portion for the reasons given below.

Mellem ydervæggen 1 og vægpartiet 7 henholdsvis skærmvæggen 4 i sin med væggen 1 parallelle stilling dannes en gangpassage med passende bredde, f.eks. 1 500 mm.Between the outer wall 1 and the wall portion 7 and the screen wall 4, respectively, in its position parallel to the wall 1, a passage passage of suitable width is formed, e.g. 1 500 mm.

Ved passende kombineret indstilling af de to skærmvægge 4 15 kan varierende afskærmningsvirkning foran indgangen 2 opnås. Fig. 2 viser en sådan indstilling, hvor afskærmnings-anordningen tilvejebringer et svagt undertryk uden for indgangen 2. Gangpassagen er her betegnet med pilen 9. I den viste anordning ifølge figuren danner afskærmningen et 20 ydre vindfang 11. En af skærmvæggene 4 er skråtstillet og vendt imod vindretningen 10, mens den anden skærmvæg er indstillet parallelt med bygningens ydervæg 1. Ved den angivne vindretning 10 indses det, at et undertryk udvikles i den i figuren venstre åbning af vindfanget 11. På grund 25 af dette undertryk hindres koldluft i at strømme ind gennem det normale vindfang i indgangen 2. Den mod vinden vendte skærmvæg 4 forhindrer tillige direkte vindtryk mod åbningen af indgangen 2.By appropriately combined adjustment of the two screen walls 4, varying shielding effect in front of the entrance 2 can be achieved. FIG. 2 shows such an arrangement where the shielding device provides a slight underpressure outside the entrance 2. The passage passage is here indicated by the arrow 9. In the device shown according to the figure, the shielding forms an outer windscreen 11. One of the shielding walls 4 is inclined and facing wind direction 10, while the second screen wall is set parallel to the outer wall of the building 1. At the indicated wind direction 10, it is realized that a negative pressure develops in the left opening of the windscreen 11. In the figure, cold air is prevented from flowing through the normal windscreen in the entrance 2. The screen wall 4 facing the wind also prevents direct wind pressure against the opening of the entrance 2.

Fig. 3 viser en modsat indstilling af skærmvæggen 4 ved 30 modsat vindretning 10. Det dannede vindfang 11 har her sin åbning med undertryk til højre i figuren.FIG. 3 shows an opposite alignment of the screen wall 4 at 30 opposite to the wind direction 10. The formed windscreen 11 here has its opening with negative pressure on the right in the figure.

Fig. 4 viser en passende indstilling af skærmvæggene ved vindstille, med mulighed for ind- og udpassage på begge sider af afskærmningsanordningen. Skærmvæggene kan her tjene som lys- og lydafskærmning, alt efter ønske.FIG. 4 shows an appropriate adjustment of the screen walls in wind still, with the possibility of entry and exit on both sides of the shielding device. The screen walls here can serve as light and sound shielding, as desired.

5 Fig. 5 viser en yderligere indstillingsmulighed for skærmvæggene 4. I dette tilfælde gør de modsat skråtstillede skærmvæggen tjeneste som ekstra tillukningsorganer foran indgangen 2, idet skærmvæggene danner ekstra sikkerhed mod ubehørig indtrængen i lokalet og kan med dette formål have 10 nødvendig kraftig udførelse med tilsvarende låsning i sin stilling.FIG. 5 shows a further adjustment option for the screen walls 4. In this case, the opposite inclined screen wall serves as additional closure means in front of the entrance 2, the screen walls providing extra security against unauthorized entry into the room and for this purpose may have 10 necessary strong design with corresponding locking in its position.

Fig. 6 viser endelig en indstillingsmulighed for tilvejebringelse af et vist undertryk, når vindretningen 10 er vinkelret mod væggen 1. Skærmvæggene er her lidt skråtstil-15 lede med det formål at afbøje luften til højre i figuren.FIG. 6 finally shows a setting option for providing a certain negative pressure when the wind direction 10 is perpendicular to the wall 1. The screen walls are here slightly inclined for the purpose of deflecting the air to the right in the figure.

Det er naturligvis også muligt at indstille skærmvæggene i en svag hældningsvinkel symmetrisk mod hinanden, så at luftstrømmen afbøjes såvel til højre som til venstre i figuren, hvorved der tilvejebringes et svagt undertryk på 20 begge sider af afskærmningsanordningen.Of course, it is also possible to adjust the screen walls at a slight angle of inclination symmetrically towards each other, so that the air flow is deflected both to the right and to the left of the figure, thereby providing a slight underpressure on both sides of the shielding device.

Skærmvæggene 4 kan være anordnede for automatisk eller manuel indstilling. Ved automatisk indstilling indstilles skærmvæggene ved hjælp af et manøvreorgan, som påvirkes af en vindindikator, så at en indstillingsposition ifølge fig.The screen walls 4 may be arranged for automatic or manual adjustment. In automatic adjustment, the screen walls are adjusted by means of a maneuvering actuated by a wind indicator so that a setting position according to FIG.

25 2 eller 3 opnås afhængig af vindretningen. Vindindikatoren kan være elektronisk koblet til manøvreorganet og påvirke dette inden for en passende retningssektor, så at optimal virkning opnås.25 2 or 3 is obtained depending on the wind direction. The wind indicator may be electronically coupled to the actuator and actuate it within an appropriate directional sector so that optimum performance is achieved.

Indstillingspositionerne ifølge fig. 2, 5 og 6 kan pas-30 sende opnås ved manuel påvirkning af manøvreringsorganet for skærmvæggene 4.The setting positions of FIG. 2, 5 and 6 can conveniently be obtained by manually acting the actuator of the screen walls 4.
