Description

Flap with safety catch

The invention relates to a flap for closing an opening in the interior of a rail vehicle, which has a safety catch.

Interior of rail vehicles have flaps for closing behind it lying rooms. In the rooms, for example, mechanical and electrical

Components can be housed after opening the flap for repairs or

Maintenance work are accessible.

The flaps are usually hinged with an edge on a wall or ceiling paneling. Unfolding such a flap would, without limiting devices, cause the flap to flip down until it is caught by the hinge. In the open state, the flap would oscillate without further support back and forth, which is disadvantageous. Also, for safety reasons too wide opening of the flap is undesirable, since in an accidental opening of the flap underneath people would be injured. It is also not always necessary for the described repairs or maintenance that the flap is opened to the maximum possible angle.

To solve these problems, tethers are proposed in the prior art, which limit the opening angle of the flap when unfolding down or to the side and largely prevent swinging back and forth of the flap in the open state.

Tethers have the disadvantage that they easily impose or jam due to their length in the room behind the flap and thus can not unfold as desired when opening the flap, whereby the flap can not be opened as desired. In addition, tethers rarely meet the prescribed fire protection.

Another solution is the use of gas springs, but which are relatively expensive, prone to failure and therefore maintenance-intensive.

Yet another solution is rigid handrails, which are arranged between the flap and the ceiling or wall and can be hooked with one end either to the flap or to the ceiling / wall, while at one end fixed to either the flap or the Ceiling / wall are connected. The handling of such fishing hook requires manual intervention by the user and therefore this solution is perceived as uncomfortable. The object of the invention was thus to provide a flap with a

Specify limiting device which limits an opening of the flap and largely prevents swinging of the flap in the open state, the limitation should overcome or substantially overcome the above-mentioned disadvantages of the prior art.

Specified is a flap for closing an opening in the interior of a

Rail vehicle having a safety catch, the safety catch being a safety belt or a safety line, which (r)

is arranged between the flap and a stationary holder,

- Is rolled up in a closed position of the flap on a roll, and

- When opening the flap of a roll is unrolled and the flap in one

open position.

The flap according to the invention has a safety catch with automatic retractor. Due to the retractor, the safety belt or the safety line is unrolled only as far as the flap is opened. In the closed state of the flap of the Fanggurt / the line is completely or almost completely rolled up. When opening and closing the flap, the automatic rewinding does not cause any disturbing influences, such as catching or pinching.

The designated leash can be either a solid string or a thin rope. The strap may be cut from a material, such as leather, or it may be fabric, preferably plastic.

The roller is preferably connected to a spring element, which is tensioned when rolling out the leash or the belt. The energy stored by tension in the spring element causes the leash or the belt to be rolled back onto the roll when the flap is closed.

The type and shape of the spring element is basically arbitrary. That's how it works

Spring element to be a radial spring element. In a radial spring element is a compression or tension of the spring element in a rotation of the roller

Circumferential direction, based on the axis of rotation of the roller causes.

The roller is preferably arranged in a housing. Thus, the leash or the belt is arranged in a rolled-up state in a housing. The housing has a Opening through which the leash or the belt can be pulled out.

Preferably, the housing is made of a fire-resistant material, such as a metal or a refractory plastic.

In an advantageous variant of the invention, the tether or the tether is made of a fire-resistant material, preferably of a refractory plastic.

The flap is preferably a downwardly opening cover flap for closing a ceiling opening of a rail vehicle wagon. The flap is articulated, for example, on a first side edge on the ceiling of the rail vehicle car and can be opened at a second, opposite side edge by a folding movement down, the flap having the tether or the tether in the region of the second side edge. The first and the second side edge preferably run in the direction of travel, but can also run transversely to the direction of travel. The first and second side edges are preferably parallel to each other. The flap is preferably rectangular.

When opening the flap, the second side edge is pivoted down and the first side edge remains, held by the hinge, on the ceiling. The flap may have one or more latches on the second side edge, for example rotatable latches. The opening of the flap can then be done by releasing such bolt. Depending on the length of the leash or the strap, the flap can be moved more or less downwards.

In a special variant, the articulated connection on the first side edge is detachable, in particular manually detachable, for example by unhooking, so that the first side edge can be exposed for disassembly of the flap, the second side edge by the Fanggurt or the fishing line, preferably by several safety straps or Leashes, is held. The term "manually releasable" means in particular that no tool is needed to solve the articulated connection and solving can be done by hand alone.

As in the previous variant, the flap is first opened on the second side edge and then folded a piece down, with the leash / belt catches the flap. Then the first edge can be released from its anchoring in the joint. The flap may then also be moved down the first side edge, being held on the side of the second side edge by the rolled-up line or rolled-up belt, preferably a plurality thereof. On the side of the first side edge, the flap can be manually However, it is also possible that one or more other catch securing are arranged as described above on the side or in the region of the first side edge, whereby the flap is also held on the side of the first side edge, if both side edges and thus the entire flap is detached from the surrounding ceiling.

In a further variant, a flap is provided, which has a first and a second side edge, which face each other, wherein the flap is a lowerable flap and at both side edges or in the region of both side edges each having one or more catch fuses, wherein the

A safety catch is a safety strap or a safety line, which (r)

is arranged between the flap and a stationary holder,

- Is rolled up in a closed position of the flap on a roll, and

when lowering the flap of a roll is unrolled and the flap in a lowered position.

The first and second side edges are preferably parallel to each other.

In this variant, the flap on the first side edge and the second side edge is released from the ceiling, for example by releasing arranged in the region of the side edges of locks, and lowered. The flap is preferably lowered parallel to the ceiling and held by the catch fuses in this position. In this variant, the flap does not pivot about a hinge axis, but it is lowered. If the flap is to be closed again, it is raised, with the leash or belt of the safety catch to be rolled up again, and locked in the ceiling.

The flap according to the invention is in particular a cover flap for covering a ventilation channel module, as described in the European patent application EP 10090013.

Such a channel module forms a running in the longitudinal direction of the car body supply air duct for supplying air into the interior of the car body. The channel module may have connections to a ventilation unit and optionally to further channel modules in adjacent vehicle parts or vehicles. The channel module is attached to the carbody ceiling and it is particularly suitable for those vehicles that have multiple vehicle areas (eg vehicle areas separated by pivoted and / or transition areas between the vehicle areas). Preferably, in the channel module, at least one side of the supply air duct is in the longitudinal direction of the Car body extending calming space designed, which is connected on the inlet side with the supply air duct and the outlet side via outlet openings with the passenger compartment, so that air from the supply air duct through the calming room and through the

Outlets can flow into the passenger compartment. Preferably, the air passes through a transition region having a reduced flow cross-section as it passes from the supply air channel into the settling chamber, the cross-sectional area of the transition region being smaller than the cross-sectional area in the settling chamber. Therefore, the air velocities decrease after entering the calming space, it can take place a distribution of air and the air occurs evenly distributed over the various outlet openings at low air velocities in the passenger compartment. Preferably, two calming chambers are located laterally of the supply air duct, on opposite sides of the supply air duct. In addition to the supply air duct, the duct module preferably has at least one exhaust air duct through which exhaust air can be discharged from the passenger compartment. The exhaust duct is, for example, if present, arranged above the calming room. The exhaust duct is in special

Configuration, unlike the supply air duct, not open by removing a channel wall, but the channel module preferably has a closed peripheral edge with channel walls, for example, on all four sides of the exhaust duct. The supply of exhaust air from the passenger compartment in the exhaust duct, for example, by

Air inlet openings in the area of the Fu floor of the passenger compartment and can be realized by channels in the area of the sides of the car body, in particular along the door pillars, and / or in the region of the car body end. Preferably, two exhaust air ducts are formed on opposite sides of the supply air duct in the duct module, wherein the longitudinal axes of the exhaust air ducts and the supply air duct are parallel to each other. In the case of only a single exhaust duct, this also applies to the longitudinal axes of only one

Exhaust duct and the supply air duct.

The ceiling flap according to the invention covers the supply air duct of the channel module downwards and forms on its underside a visible from the passenger compartment surface of

Ceiling covering, whereby the cover flap allows for cleaning and maintenance of the supply air duct after opening.

In an advantageous embodiment, the ceiling flap on an elongated profile, which extends laterally of the channel module in the longitudinal direction of the vehicle. In the elongated profile, the outlet openings are formed through which the supply air flows out of the supply air duct into the passenger compartment. In particular, the ceiling flap can be firmly connected to the elongated profile, for example glued. In a particular embodiment, there are two elongated profiles on the opposite sides of the ceiling flap and the side edges of the ceiling flap are located on the elongated profiles.

The elongated profiles may in particular be metal profiles, for example extruded aluminum sections, which preferably have guide surfaces for directing the outflowing air in desired directions.

The ceiling flap is each made of at least one molded part with fiber-reinforced and foamed thermosets. This may in particular

glass fiber reinforced phenolic foam, which is used, for example, plate-shaped with a wall thickness in the range of 6 - 10 mm.

The ceiling flap can be a high pressure laminated top layer

Composite materials (HPL), in particular a lower cover layer, the

Forming view surface for the passenger compartment. But it may also consist of the upper cover layer of the ceiling flap of the same material. In particular, the high pressure laminated composite material may be paper webs impregnated with curable (thermosetting) synthetic resins. The outermost layer, which as

Decorative layer can be referred to, preferably consists of a dyed or printed in the desired color and melaminharzgetränkten sheet paper. The

Core layers of the laminate are e.g. from paper sheets soaked in phenolic resin. Under high pressure, with simultaneous exposure to heat, the

different layers pressed together insoluble and harden to a solid, no longer softenable plate body. As a result, plastic plates of homogeneous hardness and high strength are obtained with non-porous surfaces. The thickness of the laminated cover layers may be in the range of 0.6-1.2 mm, for example.

In particular, the moldings of the ceiling tile may comprise plate-shaped sandwich material, the opposing outer layers being formed by the described laminate adhered to a core of the above-mentioned fiber-reinforced and foamed thermoset material.

The fiber materials may in particular be fiber materials from the following group of materials: glass fibers, mesoscale carbon fibers, nanoscale cylindrical graphite fibers and any combinations thereof. It is further preferred that the topcoat has a maximum average rate of heat emission (MAHRE) measured in the cone calorimeter of less than

90 kW / m ² , preferably less than 65 kW / m ² . The MAHRE value is obtained in a fire protection test in accordance with the international standard ISO 5660-1. In this case, the heat release rate of horizontally arranged samples in the ignition is determined by an external heat source. Surprisingly, it has been found that the above-mentioned material for the top layer already complies with the limit of 90 kW / m ² for rail vehicles without further addition of fire-retardant materials that do not drive through tunnels.

In the fiber reinforced and foamed thermosets used for the moldings of the

Ceiling flap are used in particular as a core material, it is preferred that the material has a MAHRE of less than 15 kW / m ² . This is the case, for example, with glass fiber reinforced phenolic foam when the wall thickness is between 6 and 10 mm.

Embodiments of the invention will now be described with reference to the accompanying drawings. The individual figures of the drawing show:

Fig. 1 shows a side view of an arrangement with a channel module 1, which is covered by a ceiling flap 4 below. The following explanations relate both to FIG. 1 and, as far as the reference numbers are shown in both figures, to FIG. 2.

The ceiling flap 4 is at a first side edge 90 on the ceiling of the

Rail car carriage hinged and is at a second, opposite

Side edge 91 has been opened by a folding movement down. The articulated connection takes place via an elongated, in cross-section hook-shaped profile part 92 extending in the longitudinal direction of the vehicle on the first side edge 90 of the flap 4, which is hooked into a likewise extending in the longitudinal direction of the vehicle enclosure 93, which is an integral part of an elongated profile 3b , To open the flap 4, the rotatable latch 95 has been opened. The flap has a catch 100 in the region of the second side edge 91. The safety catch consists of a safety line 101, which is arranged between the flap 4 and a stationary holder 102. With one end, the tether 101 is attached to the bracket 102 which is fixed to the ceiling. The tether 101 enters a housing 103 and is attached at the other end to a roller 107, which is shown in Fig. 2 in a section through the housing 103. The housing is attached to a tab 105, which in turn is attached to the top flap 4.

In the state shown, the tether 101 is partially unrolled from the roller 107. A further opening of the flap 4 down is possible, the tail line is further unrolled until it is rolled to maximum length and the flap catches. The flap can be opened as needed until the hook-shaped profile part 92 can be unhooked from the enclosure 93. However, unhooking the flap on the first edge 90 is not absolutely necessary if the maintenance work on the channel module can also take place without this measure.

The load-bearing construction is realized in the exemplary embodiment by two elongated profiles 3a, 3b extending in the longitudinal direction of the vehicle, which extend laterally, on both opposite sides of the channel module 1. The profiles 3 are preferably aluminum extruded profiles with several chambers for stabilizing the profiles. At the elongated profiles 3a, 3b are holding rods 6a, 6b fastened for passengers. The support rods 6a, 6b have angled end pieces 57a, 57b (Figure 1) which are secured to the elongated profiles 3a, 3b by screws 44a, 44b.

The channel module 1 has a central, in the longitudinal direction (perpendicular to the plane in Fig. 1) extending supply air duct 21 through which hot air and / or cold air can be performed as needed to ventilate the passenger compartment below the duct module 1. The hot air or cold air is, for example, from a known heating system and / or air conditioning. In addition to the supply air duct 21 exhaust air ducts 23a, 23b are arranged. Exhaust air from the passenger compartment enters the exhaust air ducts via air intake openings, not shown, through which the exhaust air is led to the heating and / or air conditioning system and / or to the outside.

The sectional view of Fig. 1 shows, except the supply air duct 21 and the exhaust air ducts 23a, 23b, also laterally of the supply air duct 21 and below the exhaust ducts 23a, 23b formed calming chambers 22a, 22b, which also extend in the longitudinal direction of the vehicle or the arrangement. Preferably, such calming chambers 22a, 22b are located everywhere where 1 1 air outlet openings 13 are arranged in the Luftleitprofilen.

The calming chambers 22a, 22b are partially formed by wall elements of the channel module 1. On the two legs of the U-shaped central part 71 are

Boundary plates 80, 81 with air passage openings (see Fig. 2) attached. The

Settling spaces 22a, 22b are bounded by the boundary plates 80, 81, the lower wall elements 74, 75.
