"Door with door leaf that can be raised and lowered mechanically ¹¹

The invention relates to a gate with a mechanically lifting and lowerable door leaf, retracted in the open state in a depression in the floor, next to it to guide it The goalposts arranged for the goal opening are used.

wherever fences * cross traffic routes extend away, wisbeispieloTrsis ^ SisfahrtstraSss, G-I ice body or the like, gates are required. Began is to design such gates as sliding gates or swing gates

^ to form. Because of this design of the goals there is the disadvantage that a relatively _; Large area next to the door or behind the door must be kept free for the door leaf that moves away or swings away when it is opened. In the case of sliding gates in particular, when the gate width is large, the gate leaf also has extremely large dimensions, which lead to further, very considerable disadvantages. Long door leaves are often no longer transportable and

therefore often have to be prefabricated in individual parts and attached to the

Assembly point to be assembled. The large dimensions of the known sliding or swing gates also lead to the further disadvantage that their dimensionally large weight must be absorbed in the area of the goal posts. This results in order to achieve the necessary inherent stability door panels, the ^ by appropriate design (design of high static load capacity are. These door panels are complex and expensive. In their structural design continues to be a relatively high weight, this weight can not be avoided. Must again to the goal posts recorded and derived, which results in further structurally complex measures.

It is known that the described ITaehteile of the wing and sliding gates _{3 can} at least partially be avoided by the fact that the door leaf can be raised and lowered - is guided on the goal post, so that the one-sided strong static load on the door leaf as well also the post is avoided. With regard to the dimensions, in particular transportability, no improvement whatsoever is achieved by the raising and lowering of the door leaf. The free tree required for wing and sliding gates next to or behind the gate opening can be saved for this; because the door leaf moves into a recess in the floor when it is opened. The alternative option is to move the door leaf upwards in

Raising appropriately high-trained guide rails when the door is to be opened is prohibited because of the associated disfigurement of the architectural effect and also because of the requirement for an unlimited passage height. The known gates with a liftable and lowerable gate leaf can, however, despite the described "advantages over the sliding and swing gates" only be used in exceptional cases, because a recess in the bottom is required to sink them when opening the gate, the depth of which includes the surcharges for the masonry and In the case of gates with a door leaf height of two or often more meters, it is necessary to create pits for the depressions in the ground that are correspondingly deep create, because in the area of, is 5? -ORe often f \ also supply connections, piping, etc. Eabel extend. the expense resulting to low lying areas to create such dimensions and also to protect against groundwater is unacceptably high.

The invention is based on the described disadvantages of the known goals. avoid and one. in the manner mentioned at the beginning with a liftable and mustard-type Door leaf disengaged; et es! Por to train so that it "with simple Construction work in comparatively flat Soöenvertie-

In order to achieve the above-mentioned object, the gate mentioned in the introduction is characterized according to the invention in that the Door leaf made of articulated interconnected rigid individual elements each extending over the entire width of the door is composed, which is in the locked state under the leading influence of the side goalposts held in a common plane in a stretched position, in the open state offset to one another at an angle and / or transversely to itself under the influence of a receiving device as Stacks or rolls are received in a recess that is flat compared to the height of the door leaf.

The fact that the gate according to the invention is a hinge-like Has connected individual elements composite door leaf, there is the possibility of this door leaf under Use of the articulated connections between the individual elements to convert them into compact folded or wound states. In the rolled up or folded state, however, the door leaf takes up little space, so that initially result in simplifications with regard to the transport dimensions. In addition, however, the door leaf can also be comparatively Place shallow depressions in the bottom so that when the gate is opened, large depressions are not, as was previously the case

is "already known to sicli, goals made of individual elements to! form that extend horizontally "and articulated are. Such gates are "so far designed like blinds and are mainly used as garage doors or internal gates of industrial plants to "close building openings or the like. With these known gates, however, a nickel or guide device is used over the gate opening provided, which by means of a mechanical drive Door leaf in guide rails lifts when the door is open and pushes it down again when the 2or is to be closed.

'This known application of a door leaf composed of articulated individual elements is, however not suitable to present a solution to the problem on which the invention is based; because it was already at the beginning mentions that the gates in Eede have structural elements which extend across the door opening above the doorway are not permitted because they constitute a restriction the free passage height of the gate. In addition, the winding or pulling devices are known Doors with shutter-like door leaves are always protected from the effects of the weather inside buildings arranged.

^S he design of the liftable or lowerable door leaf, which according to the invention can be retracted when the door is opened into a recess that is flat in relation to the height of the door leaf, can be implemented in many different designs.

With such a design, the invention provides for example before that the drive device used for mechanical lifting and lowering of the door leaf is located in the floor recess is arranged and - at least one for each goal post when closing - effective, on the topmost individual element having attacking lifting device.

In another advantageous embodiment of the new ToreS, the drive device is additionally geared connected to the receiving device counteracting the lifting device when the gate is opened. In this training A perfect guidance of the individual elements of the door leaf is guaranteed at all times.

In the case of the new goal, the lifting device can be in the form of a threaded spindle rotatably mounted in the goal post and a this recorded threaded nut be formed.

Another possibility for training the lifting device consists in designing this in the form of a rope or chain hoist. File can be changed depending on the training of the recording establishment is an essential part of "structural" Achieve simplification if the rope or chain hoist is equipped with a cord or an endless chain.

Also, the receiving device, which serves the door leaf te ± m Open taking advantage of the joint connection between the individual Diem ducks in a FaIt- or Vickelzustand to transfer, is virtually verwirklicnen in many different ways. In a preferred embodiment of the goal, the receiving device is designed and effected as a fork-shaped guide groove, which is arranged in the floor recess and adjoins the goal post, for pins protruding laterally from the individual elements
