DE19542691A1 - Swinging wing door for lorry - Google Patents

Abstract

The door comprises a swinging wing plate consisting of two easily mounted foil plates which are highly polished and glass fibre reinforced by trapping air in resin. It is also reinforced by intermediate spacers are glued together so that a layer of air of several centimetres thickness is between them and is such that an air insulating rigid flat wall can be used. The plate acting as a lorry's swinging wing door by its outer skin allows drizzle to slide directly to the ground behind the vehicle by the headwind induced vacuum.

Description

Truck loading doors are well known. Almost all of them have a 2-winged one heavy door, consisting of two halves, which in the middle by heavy locking be held together.

There are also a few roller shutters. These are usually not too for truck-trailers use.

Shipping containers are also heavy-weight doors and heavyweight hinges attached so that these can only be opened with lever tools after a few years are.

A big disadvantage is common to all doors, that these doors through attached hooks and eyes, Rails and folds are very bad advertising media. Also due to broken down trucks, without lighting, are already very many losses due to rear-end collisions To complain about human life.

Another major disadvantage is the wind generated by the airstream Air swirls, especially in rainy weather, because this vortex significantly increases the amount of follow-up traffic with special needs.  

The new swing swing door receives one Drive, which opens after the rope jumping effect or can be closed in such a way that this in can stay in any position without braking device. For this purpose, a framework is at the end of the truck built up.

In the middle of the framework are left and right two face plates rotatably arranged. One of these face plates has a V-belt groove. A compression fitting is located at the top. With this compression fitting two wire ropes, which are passed through the groove. In the lower area is a wave with a four or Hexagon also rotatably mounted.

One end of the wire rope is on the shaft around the Half-face of the faceplate through several left turns fast-forwarded the wave.

After that, the second end of the wire rope with the shaft anchored tensile.

There is a half frame between the two face plates screwed tight after the rope jumping effect. At the bottom of the half frame are in the frame preferably arranged rubber wheels.  

Two were made especially for this construction Glass tiles from glass plates glass fiber reinforced Peeled off slides.

Two panels each are 6 m long a width of 3.21 m, so that the mirrored surfaces face outwards.

Between the two surfaces are empty pipes, which with glass fiber reinforced fleece coated and freshly soaked are firmly installed between the plates, so that after the Hardening creates an approximately 40-50 mm thick rigid wall. Because the tile is a tile with a lot Air mats are involved, these mats also take about 30% less resin, so that these plates very are easy to handle and an element 2.50 m high and 1.50 m wide easily carried by one person can be.

Since such a plate in the horizontal position in the Longitudinal direction, d. H. in the direction in the empty pipes are misplaced, and possibly upper and lower probation is only a very small one vibrating deflection possible.  

Panels constructed in this way are also used e.g. as street signs. They are special too suitable as guard rails because they do not rust and can simply be anchored securely. These are also cut into strips of 500 mm Radius to lay and offer a less dangerous Impact protection.

A plate cut to size is now in the upper frame of the truck stored and in the lower Area anchored with slide latch. Lateral guide anchors give this swing door a test stop. Conversely, the swing door also creates a fixed one Framework created.

Additional plate elements give the truck a fixed conversion Box profile. This also applies to the roofing.

This swing door can now be installed from the outside opened with a crank, placed on the square will.

After unlocking, turn to the right Faceplate moved to the right by the wire rope and the intermediate half frame is released after unlocking moved forward.  

The pre-wound wire rope is unwound and moved up on the faceplate. With further right movements, the half-frame becomes wider moved up.

By further turning it is possible to open the swing door can also move over 90 °, making it effortless Loading and unloading is possible. Closing takes place in the same order in the left turn.

So that the follow-up traffic from the whirling airstream, especially when it rains, is not hindered on this Swing door with an additional GRP plate film Luminous pigments arranged.

This plate has an internal appearance Indentation seen from above a sine line equal.

This arrangement creates the back of the Driving a vacuum in the bulge.

This leads to the fact that the headwind is at the rear Let the vehicle slide to the ground and follow-up traffic is significantly less hindered or harassed. Such swing doors can also be excellent use as garage or entrance doors. For example, at a hall entrance gate of the Swinging wing guided over a roller in the upper area.  

The upper ends are stored in a trapezoidal swing. The swing ends are attached to the hall ceiling. Now the swing door by means of the half frame moved up, so the half frame is in the lower Area of the swing door firmly locked.

By opening it again, the swing is inside the Hall driven.

Tension springs can also be arranged between the rope ends be.

The drive can of course also be done electronically and the panels can also be translucent, windows replace.

Such plates can also on the outer edges be foamed so that the standing air is good Isolation represents.

The same arrangement can also be found in all car garages be used.  

Based on a schematic representation the invention are described in more detail:

Fig. 1 shows the Hinged Hinged Hinged Door No. 3 with a HGV Box Frame No. 1 made of Hinged Hinged Panels No. 2 . Provided that a vacuum suction cup is attached to the lower area, these swinging wing plates can be removed by releasing a locking device in the modular system.

These plates are engaged with the box frame no. 1 anchored.

They give the entire truck box frame No. 1 a test hold.

In the truck box frame No. 1 , a solid frame No. 4 is firmly connected to the truck box frame No. 1 .

In frame No. 4 , 2 face plates No. 5 are rotatably mounted opposite each other.

A wire rope No. 6 is stretched over a rotatably mounted axle No. 7 over these face plates No. 5 . By turning the No. 7 axis clockwise with a No. 8 crank, the No. 5 face plates, which are connected to the No. 5 face plates by a No. 9 half frame, are moved out of the No. 4 frame.

Through this outward movement, the swing door no. 3 mounted in the upper frame No. 4 is moved upwards via wheels No. 10 .

By turning the axis No. 7 further clockwise, the face plates No. 5 with the half frame No. 9 stored between them are moved upwards with the aid of the No. 6 rope, the wire rope No. 6 unwinding on the No. 7 axle.

Positions No. 11 and No. 12 show the wider opening angle.

The face plates No. 5 are each arranged in the upper third of the frame No. 4 .

Vacuum-pulling GRP foil panels No. 13 are arranged on the swing door No. 3 .

Luminous pigments are embedded in this vacuum-pulling GRP film plate no. 13 , so that even if the entire lighting fails, the follow-up traffic can recognize this obstacle over a large area.

The swing door no. 3 is closed in the reverse order.

Fig. 2 shows the truck box frame No. 1 with the swing door No. 3 open, which is mounted on the wheels No. 10 and on the half frame No. 9 .

The vacuum-pulling foil plate No. 13 with vacuum-pulling recess No. 13 a is attached to this swing door No. 3 .

Fig. 3 shows a swing wing plate No. 14 with intermediate empty tubes No. 15 , GFK coated, arranged so that the two foil plates No. 16 u. No. 17 are glued with GRP so that the wing plate no. 14 is created. Between the empty tubes no. 15 , empty tubes or probing sleeves no. 18 can also be inserted transversely, so that a rigid wing plate is formed, which, for. For example, can be used for street signs.

Fig. 4 shows the swing wing panel No. 14 cut into strips as guard rail No. 19 . This guardrail No. 19 is clamped on a holder No. 20 .

The holder no. 20 has a stop no. 21 and a foot column no. 22 , which is supported in an earth-anchored concrete column no. 23 . This guardrail no. 19 includes in addition to the empty pipes no. 15, no intermediate probation No. 18,.

Fig. 5 shows the guardrail No. 19 with the empty tubes No. 15 , but is without the probation No. 16 , which makes it possible to have the guardrail in a radius, e.g. with input u. From rides to relocate.
