Hinged gates or doors

709804/1072

I NACHQERQCHT

The present invention relates to gates or doors, and more particularly to gates and doors to be used in wide driveways or access openings where a number of separate doors are placed must, since a single door would be too cumbersome and difficult to manufacture so rigid that it is not damaged in use.

Very wide access or driveways or openings are generally used used on fixed structures or buildings or moving structures such as vehicles into which large and heavy objects are moved have to. Such access routes are often closed by means of doors, especially in buildings, which consist of a number of rails on the floor and the ceiling of the access road are made of door sections that continue to be connected to one another in a hinge-like manner at their vertical edges are.

However, such door structures are very difficult and difficult to operate and also have the distinct disadvantage that the entire driveway must be opened at once in order to gain access to a proportionate get small area.

Furthermore, such large and heavy doors are very impractical when they are to be installed in a vehicle. If, on the other hand, a number of separate hinged doors are provided that run along

one of their side edges can pivot, difficulties in access occur to the cargo space behind the hinged edges of the door.

709884/1072

The present invention provides a gate or door that between an open and a closed position by a selected one of at least two of its edges can be pivoted, each of the side edges being pivotally connected to an elongated element, which can be locked in a doorway with suitable facilities. The arrangement is made so that the elongated element of the selected an edge in the doorway in the target position can be blocked while the other element or elements can be released, so that the gate can pivot around the element on this one edge.

Preferably the gate is constructed to be around both of two opposing ones Side edges is evident, so that when a plurality of such gates over a wide opening such as. Along the side of a long Vehicle is arranged, each pair of adjacent door sections can be opened to provide uninterrupted access to a room create, the width of which is substantially equal to the total width of the two open gate sections. In this preferred embodiment the elongated elements are preferably designed to be lockable with the doorway by moving them over the upper and lower edge of the door parts protrude and the extensions fit into suitable recesses or sockets on the top and bottom of the loading opening. This arrangement eliminates the need to place interfering supports between the top and bottom edges of the loading opening so that you always there, where a pair of door parts is opened, is given a completely free space.

? 09884/1072

The depressions can also, instead of being stationary, sit on sleds that run on rails along the side of the vehicle so that the door parts can be

'can be pushed to one side to reveal an old-' native method to allow opening of the gate.

In a preferred embodiment, each is elongated Element tubular and each recess has a front opening which is essentially as wide as the diameter of the pipe. The end of the tube carries a radial approach so that it is in the recess with after forward facing radial approach can be inserted, and can be turned with a handle or the like. To the radial Establish approach behind a suitable stop in the recess.

Since the gate itself is pivotally attached to the elongated tubular member, this rotation of the tubular member can be calibrated without moving the door yourself.

To make it easier to insert the tubular element into the recess, allow its extreme end and that of the radial attachment to be beveled. This is particularly useful in the case of long vehicles in which the tubular element fits between the upper and lower edge of the loading opening with close tolerances

is to contribute significantly to the structural rigidity of the vehicle.

In the pivot bearing of the gates and doors disclosed above it does not make sense to arrange the gates or doors so that an opening in the vehicle body or cargo container is completely closed will. For geometrical considerations with regard to the door hinges, it is necessary to have a gap between the to leave individual door or gate sections. Thus the arrangement is not as disclosed in that application suitable for applications in which an opening has to be closed completely, e.g. to meet the TIR regulations.

Thus, in order to provide an improved arrangement which enables the doors or gates to completely close an opening in a vehicle body or a cargo container, a cover arrangement is provided for closing the opening between the gates or doors. Preferably, each elongated element is provided with a plate which represents a cover device and, when the element is locked and the gate or the door is in the closed position, the gap between adjacent gates or doors or the gap between a gate or a door and a fixed part of the doorway or the door opening alone or together with the plate of a

709884/1072

adjacent elongated element closes.

The Pig. Fig. 1 shows the side of a vehicle body (without the chassis or drive parts, of course) of a type intended for side loading with, for example, a forklift or the like. Thus, the cargo space can be loaded within the vehicle, body over its entire length effectively, six separate gate 2, 41 6, 8, 1o and 12 are provided and respectively arranged so that they can be opened pivotally to both side edges. This gives you access to continuous areas of -example - the end 14 of the vehicle to point 18 along its longitudinal dimension or from point 16 to point 2o along the vehicle, etc.

Fig. 2 of the drawing now shows that the gate 4 has a rectangular steel frame 22 which is a steel wire mesh 24 has a mesh size of about 50 mm. The frame 22 is attached to tubular members by means of the collars 26 along each side edge 28 or 3o attached, the ends of which above and below the upper or. The lower edge of the frame 22 protrude.

The ends of the element 28 sit in recesses or sockets 36, which are generally above and below the left side edge of the gate 4; the ends 34 of the tubular element are also seated 3o in depressions or sockets 38 above and below the. right side edge of the gate. The two pipe elements are each provided with radially protruding handles 4o and 42, by means of which they can be resolved to get out of the

709884/1072

Vehicle frame to be lifted out as detailed below is explained

As now shown in FIGS. 3 and 4, the recess or the socket 38 is a cut away Part of a box profile that runs along the lower side edge of the vehicle's cargo space. The depression opens to the front, the width of the opening corresponding to the diameter of the tubular element 34, so that the tubular element 34 in the recess can be pushed in and out of it horizontally. As can be seen from the general arrangement in the 2, the sockets are arranged in pairs, as the plan view of FIG. 4 shows more clearly.

A short piece of round metal 44, the length of which is chosen to fit snugly between the upper and lower inner surfaces of the box section 46 along the edge of the vehicle is to one side of the extreme end of the member 34 welded on and forms a radial approach there. As you can see the handle 42 is attached to the diametrically opposite side of the element 34 and is therefore in the opposite Direction forward.

As can be seen in the top view of FIG. 4, the radial attachment 44 engages when the door is in the closed position

7G988W1072

each tubular element 34 behind a stop which is part of the front surface of the box section 46 on the socket 38. if the gate is to be swiveled open around the element 28, for example in order to gain access to the gate extending from point 16 to point 2o in FIG To obtain area, the tubular element 29 is left in the blocking position, as shown in Fig. 2, but the handle 42 of the tubular element 34 rotated by 9o counterclockwise (in plan view) until it assumes the position shown in broken lines in FIG. 3. At this point the radial extension 44 is located behind the tubular element 34 (as seen from the side of the vehicle), so that the tubular member 34 can be pulled out of the socket in the direction shown by arrow A by simply on handle 4? pulls. It will be appreciated that the location of socket 38 at the top of element 34 is exactly that at the bottom Corresponds to the end of the element, but there is no need to provide another handle there than the upper one End of element 34 moves simultaneously with the lower element.

By actuating the locking mechanism of the adjacent tubular element 46 of the gate 6 in order to free it from the fit 38, the gate 6 can be pivoted about the opposite edge, as can be seen from the view in FIG. In this way, the entire space between points 16 and 20 can be opened over the length of the trailer without interfering intermediate elements.

709884 / 1Q72

In order to facilitate the insertion of the rollers and their radial seating in the depressions when the gates are to be closed again, the lower edge of the attachment can be beveled, as shown at 5o. Alternatively, and preferably, the collar extends partially over the end of both the radially protruding lug and the tube and may be offset relative to the lower edge of the lug so that the end of the tube slides over the leading edge 52 of the recess 38 when the tube member is inserted into the foliage is pushed. This feature has proven to be particularly useful since it counteracts the natural iMeigung the frame, clotting _o fügig by zuhängen.

It has also been found that it is useful to move the radial extension at the upper end of the element 34 slightly in Uinf alignment with respect to the extension at the lower end, so that the upper extension reaches the locking position a little earlier than the lower. With this arrangement and the tubular element fitted with tight tolerances between the upper and lower side edges of the vehicle body, the tubular elements add significantly to the overall rigidity of the body when all of the gates are closed. In addition to their role as movable hinge elements, they become part of the vehicle body when the gates are closed.

As an additional feature, in order to increase the Vie Lwei ti _o kei t of _t -'ahrzeugs, aie recesses in the rails entlctn ^ aer ooereti and bottom edges are fiir not fixed in the edge of the vehicle disposed jeaeti gate, but in sled, the The vehicle can be moved, but can then be moved sideways instead of being swiveled out, which can be an advantage in certain cases.

The Ausführun ^ sForm zei _o t described above, that is, a structure in which a gate or door can be pivoted about one of at least two edges. rJine such Anordnun _u is advantageous in that each two adjacent doors open to unobstructed ziu ^ ang to an enclosed vehicle body to provide, while at the same time the item to which pivots the door as l'engined for the roof of the vehicle body serves.

As now in particular in Fig. 6 ^ ezei ^ t, it is in the vehicle shown there to a semi-trailer truck with gate or doors according to the present invention. It's closed see that the body shown is completely enclosed on a trailer chassis; but he can also do the same on a normal truck chassis, or on a rail chassis be arranged or in the form of a freight container carried by such vehicles. the

BATH ORIGINAL

Gates or doors according to the present invention are arranged so that they form the side panels of the body and are mounted in the manner shown in Figures 1 and 4 so that they can be opened by a pivoting movement around one of their two edges, a selected part of the body side surface becomes accessible for loading or unloading. Here, too, the doors or panels can be completely removed, as shown in Figs. 6A and 6B.

In eggs in yig. 7 is each gate or each Door ^ o hinge-like on each of its vertical edges elongated element 51 posted, which in a Randj schienenabsclinitt 64 (rave ") on the lower edge of the platform of the body and engages in a corresponding box section 62 on the upper edge of the vehicle body and rotates, namely in both cases exactly as with the tubular elements 28, 3o, the

I are explained above with reference to FIGS. The elements 51 are each provided with a handle at their lower end 52, with which they can be rotated in the same way as explained above with regard to FIGS was to release the elements from the vehicle body and thus to open the gate or door 5o.

In the embodiment of FIG. 7, the elongated white Element 51 is an elongated plate 6o with a tubular element

61, which is welded at its upper end and comes into contact with the box section bZ of the body, furthermore a lower tubular part 63 is welded to the lower end of the plate and comes into engagement with the box section in the platform of the vehicle body. A rod 65 is rotatably located between the Kohrelemente 61, 63 and runs in an intermediate bearing 66 so that the stand is rotatably mounted on the element 51. The gate or gate 5o is rigidly attached to the rod 51 so that it can pivot on the elongate element 51.

The arrangement of the plates 6o is made so that the plates

• Adjacent elements 51 in the side of the vehicle

j body work together to close the gap between the I
Cover elements and the gap between the elements and; to cover the associated gates or gates 5o. In order to further develop this, seals 67 are provided on the vertical edges of the plates 6o, which cooperate with corresponding diameters on the adjoining plate 6o and with the corresponding gates or doors 5o. The plate 6o of an element 51 at the end of the body opening cooperates with the kahien of the body in a corresponding manner to close the gap between the last door and the frame. The edge rail profiles 62, 64 are preferably provided with webs, as shown at 68, to which suitable sealing strips 69 on the upper

and put on the bottom of the cutter or door 5o.

It can therefore be seen that when the doors or gates are swiveled into the closing position and the elongated elements 51 are fixed, a completely closed and essentially dense vehicle is created, at deal the plates 6o, the gaps of adjacent gates or doors 5o and the last gate or foren and close the body frame, by rotating certain of the elongated elements 51 by means of the handle 52, the gates or doors can optionally be swiveled open or removed, as it relates to the ¹ Ji ^. 1 and 4 has been described.

The? I _o . 8 shows a slightly modified arrangement compared to that of the Pi j. 7, v / o parts with the same construction or function have the same designation and are not explained further.

In this arrangement, the elongated element 51 is provided with a vertical 3tan ^ ^e 7o which is rigidly attached to the plate! 6o sits. The gates or 'doors 5o are equipped with bearing sleeves 71

see who can turn on the rod 7o and that way

the gate or the door 5o pivot on the element. In this arrangement, too, the plansches 68 are provided with seals which lie against the inner edges of the gates or doors 5o .
