Abstract
A space for treating and/or storing products, crops and the like comprising upwardly extending walls, a floor, a ceiling and a door shutting at least part of one side of the space and being movable at least substantially in a horizontal direction away from and towards said space for opening and closing the same respectively, whereby the door and supporting members associated with the door are designed so that in the closed position of the door, the door occupies a sloping position such that, viewed in the direction of displacement of the door, when the door is closed, the top end of the door is located in front of the lower end of the door.
Description
- The invention relates to a space for treating and/or storing products,crops or the like comprising upwardly extending walls, a floor, a ceiling and a door shutting at least part of one side of the space, said door being movable at least substantially in a horizontal direction away from and towards the space for opening and closing the space respectively.
- Such a space is known from Dutch Patent Application 7602243. In this construction the door may form an entire wall or a large part of a wall of the space so that, when the door is open, the space is accessible through a large passage and lifting trucks or the like can drive in. Such a construction is very satisfying in practice.
- In treating and/or storing certain products, crops or the like, for example, in growing given crops in the space, it is, however, often necessary to obtain a given excess pressure or a given subatmospheric pressure in the space. In the conventional construction known from Dutch Patent Application 7602243, in which the door, when closed, is in a vertical position, difficulties may arise in ensuring a satisfying seal of the space in the area of the door, when the door is in the closed position.
- The invention has for its object to provide a space of the kind set forth above in which the aforesaid disadvantage can be obviated in a simple manner.
- According to the invention this can be achieved in that the door and the supporting members associated with the door are designed so that in the closed position of the door, the door occupies a sloping position such that, viewed in the direction of displacement of the door, the top end of the door is located in front of the lower end of the door, when the door is closed.
- When such a construction is employed, the weight of the door will contribute to maintaining the door in the closed position, so that ensuring a satisfactory seal in the closed position of the door in the area thereof will be facilitated.
- The invention will be described more fully hereinafter with reference to the accompanying Figures.
- Fig. 1 shows partly in an elevational view and partly in a sectional view part of a space embodying the invention.
- Fig. 2 shows a detail of a modified embodiment.
- From Fig. 1 it is apparent that a
space 1 is bounded by upwardly extending walls 2, a ceiling 3 and a floor 4. An open side of the space is closed by adoor 5. Thedoor 5 comprises two relatively parallelwooden beams 6 and 7 located near the top side and the bottom side respectively of the door and interconnected near their ends by wooden beams (not shown) extending upwardly from the ends of thebeam 7 to the ends of the beam 6. To this square or rectangular framework formed by the wooden beams is fastened on the side remote from the space 1 acorrugated plate 8 and on the side facing the space a flat cover plate 9. The space surrounded by the beams and enclosed between theplates 8 and 9 may effectively be filled out withinsulating material 10. - Along the underside of the
beam 7, on the side facing thespace 1, is arranged asealing strip 11 of rubber or a similar, elastic material. In a similarmanner sealing strips 12 of rubber or a similar, elastic material are provided along the beams interconnecting the ends of thebeams 6 and 7 on the side of said beams facing thespace 1. In the closed position of the door shown in the Figure the underside of thesealing strip 11 and the lower ends of thesealing strips 12 are bearing on the top surface of thefloor 11. - The sides of the
sealing strips 12 remote from thedoor 5 are bearing on upwardly extending wooden supportingmembers 13. From the Figure it will be apparent that these wooden supporting members are tapering from bottom to top, whilst the sides of the supporting members facing the door are at a small angle to the vertical so that the lower ends of the sides of the supporting members facing the door are further remote from an upright wall of thespace 1 opposite the door than the top ends of said sides of the supporting members. In this design thedoor 5 bearing with thesealing strips 12 on the supportingmembers 13 occupies a slightly sloping position as is illustrated in the Figure. In the closed position of the door a sealing strip (not shown) fastened to the beam 6 is in sealing engagement with a head partition of the top wall 3. - The door is supported by a plurality of
carriages 15 each provided with two freelyrotatable rollers 16, which can roll along relativelyparallel rails 17 supported at a desired distance above the floor 4. It will be apparent from the Figure that in the closed position of the door therollers 16 of thecarriages 15 are located in downwardly bent-overends 18 of therails 17, which, viewed on plan, extend at right angles to thedoor 5. With the aid ofpivotal shafts 19 extending parallel to the rotary axes of therollers 16 and parallel to the front face of thedoor coupling rods 20 are coupled with the carriages. Thesecoupling rods 20 are fastened tocarriers 21 which are pivotally connected with U-shapedbrackets 23 secured to the top beam 6 of the door with the aid ofpivot pins 22 perpendicular to the front face of the door. - In
supports 24 rotatably fastened to the door is rotatably journalled ahorizontal shaft 25 extending parallel to the front face of the door. With the aid of a driving mechanism (not shown) theshaft 25 can be rotated about its centre line. To theshaft 25 are fastenedgear wheels 26, which are in mesh withtoothed racks 27 occupying a fixed position and extending parallel to therails 17. - The
toothed racks 27 are not displaceable in a direction of length, but the right-hand ends of the toothed racks, as viewed in Fig. 1,can move up and down to follow the movement of thegear wheels 26. - For opening the door the
shaft 25 can be turned so that thegear wheels 26 will roll along thetoothed racks 27 and the door will be displaced to the left as viewed in the Figure. Therollers 16 will first move along the inclined, bent-overpart 18 of therails 17 and thus lift the door from the ground, whilst the door will occupy a vertical position when therollers 16 are located in the horizontal parts of therails 17. Closing of the door is performed in the reverse order. When therollers 16 reach the downwardly inclined parts of therails 17 the lower end of the door will be at least substantially in contact with the lower ends of the supporting members, after which the door moves down so that thesealing strip 11 and the lower ends of thesealing strips 12 come into contact with the floor and are slightly compressed by the weight of the door. Viewed in the direction of movement of the door the top end of the door will move further than the lower end so that the door will occupy the inclined position shown in the Figure, in which position the door is held by the supportingmembers 13. In this inclined position thesealing strips 12 are slightly compressed on the supportingmembers 13 by the weight of the door so that in the areas of thesealing strips 12 and the sealing strip fastened to the top beam a satisfactory seal is obtained by the action of the weight of the door, even when pressure fluctuations occur in the interior of thespace 1. - The
sealing strips 12 and the sealing strip near the top side of the door may, as an alternative, be fastened to the supportingmembers 13 and thehead partition 14 respectively so that they do not move with the door. - Such an arrangement reduces the risk of damage.
- In order to further tighten the sealing strips, the construction shown in Fig. 2 can be used. Therein near the sides of the door the
lower beam 7 or the like has fastened to it projectingarms 28 having inclined guide faces 29 co-operating withguide rollers 30. The disposition is such that, when the door is near its closed position but has not yet moved downwards during the closing operation, the lower ends of the guide faces are located just on the right-hand side of the topmost points of the guide rollers as shown in Fig. 2. - When the door moves downwards during the last phase of the closing movement, the door will be urged to the right as viewed in Fig. 2 as a result of the co-operation of the guide faces 29 with the
rollers 30, so that the sealing strips are more tightly pressed home and the lower end of the door is guarded to some extent. - The reference numerals in the Claims do not have a limitative function on the interpretation of the Claims and solely serve for clarification.
