[0001] Description
[0002] Track-guided vehicle
[0003] The invention relates to a track-guided vehicle with a side window. The side window comprises a frame, a sash, and a guide track. The frame is designed to accommodate the sash in a closed position.
[0004] Currently, high-speed trains only use pivoting windows due to the pressure-tightness requirements at high speeds of, for example, 300 km / h. These have two end positions: fully open and closed.
[0005] In the fully open position, these protrude into the driver's cab and thus into the areas of the attendant or folding seats. This means that staying in these seats is restricted or impossible while the window is open.
[0006] In the closed end position, the locking system used in casement windows, unlike current sliding window solutions, increases the contact pressure and thus creates pressure tightness.
[0007] Currently, the only solution is to endure the restricted seating position when using casement windows or to leave the seat for the duration of the window opening.
[0008] Based on this, the object of the invention is to create a rail vehicle with an improved side window.
[0009] This problem is solved by the track-guided vehicle of claim 1.
[0010] Advantageous embodiments and further developments are the subject of the subclaims.
[0011] According to the invention, a track-guided vehicle with a side window is provided. The side window comprises a frame, a sash, and a guide track. The frame is configured to accommodate the sash in a closed position. The sash is movable between a closed position and an open position along the guide track. In an open position, the sash is arranged completely outside the frame.
[0012] In the open position, the sash and frame are spaced apart from each other.
[0013] The open position is a position that allows the side window to be fully opened when the rail vehicle is stationary.
[0014] The closed position is the position in which the side window is to be positioned while the rail vehicle is moving. This position allows for pressure-tight closure of the side window, ensuring pressure-tight closure even at higher speeds, preferably above 250 km / h, and furthermore preferably above 300 km / h.
[0015] The invention described makes it possible to open the side windows without restricting the space in front of the companion and folding seats.
[0016] For the closed end position, it is possible to increase the contact pressure during initial setup or for corrective maintenance in case of insufficient pressure tightness or to reduce it if excessive actuation forces are required.
[0017] In the design of the rail vehicle, it can be provided that the side window is designed to perform a pivoting sliding movement.
[0018] In the design of the track-guided vehicle, it can be provided that the frame has at least one first plug-in pivoting element and the wing has at least one second plug-in pivoting element.
[0019] This creates a mechanism next to the guide track that allows the window to pivot. The first plug-in pivot element and the second plug-in pivot element are designed such that they interact and, as the sash approaches the frame, are inserted into each other in the area of the first plug-in pivot element and the second plug-in pivot element to form a pivot element.
[0020] In the design of the track-guided vehicle, it can be provided that in the closed position, the at least one first plug-in pivot element and the at least one second plug-in pivot element abut one another and form a common, preferably vertical, pivot axis about which the wing can be pivoted relative to the frame between the closed position and a pivot position.
[0021] This ensures that a pivot axis is formed by two separate elements and the frame is designed to be displaceable along the guideway and pivotable about the pivot axis.
[0022] In the design of the track-guided vehicle, it can be provided that the guide track is arranged outside the frame.
[0023] This ensures that the frame has limited dimensions and can be pressure-tight. Furthermore, the window can be fully extended from the frame because the guide track is located outside the frame.
[0024] In a design of the track-guided vehicle, it can be provided that the guideway is designed such that the wing is spaced orthogonally to a frame plane in an intermediate position and / or the open position, and / or partially overlaps an opening in the frame in the intermediate position, and / or preferably does not overlap the opening in the frame in the open position. "Spaced orthogonally to the frame plane" means that there is a distance from the frame plane in the direction of a surface normal to the frame plane.
[0025] This ensures that the wing can be moved independently of the frame along the guideway and is completely decoupled from the frame in the intermediate and open positions. In the embodiment of the track-guided vehicle, it can be provided that the at least one first plug-in pivot element and the at least one second plug-in pivot element are spaced apart from one another in the open position and / or in the intermediate position.
[0026] This allows for flexible positioning of the sash in relation to the frame.
[0027] In the design of the track-guided vehicle, it can be provided that the wing can be locked in the guideway in the closed position and / or in the pivoting position and / or in the intermediate position and / or in the open position.
[0028] This allows the sash to be set to several fixable positions, locking it into place accordingly. Furthermore, the different positions of the sash allow for natural ventilation.
[0029] In the design of the track-guided vehicle, it can be provided that the guideway has an upper rail and a lower rail, wherein the upper rail and the lower rail each have two guide curves for guiding the wing.
[0030] This ensures that the wing is guided on both its top and bottom sides.
[0031] By creating two guide curves per rail, it is also possible to achieve flexible positioning of the sash.
[0032] In the design of the track-guided vehicle, it can be provided that the wing has at least one guide element for each guide curve to guide the wing in the guideway. This ensures that a special element of the wing allows guidance along the guide curve.
[0033] In the design of the track-guided vehicle, it can be provided that at least one guide curve, preferably one guide curve per rail, has locking points into which the at least one guide element can lock, wherein one locking point per locking point is assigned to the closed position and / or the pivoting position and / or the intermediate position and / or the open position.
[0034] This ensures that a large number of wings can be locked into each position.
[0035] In an embodiment of the track-guided vehicle, it can be provided that the frame has at least a first locking element and the wing has at least a second locking element and, in the closed position, the first locking element and the second locking element can be brought into engagement to lock the side window.
[0036] This makes it possible to lock the window securely and ensure appropriate pressure tightness.
[0037] In this case, locking elements, the at least one first locking element and the at least one second locking element, act to establish pressure tightness.
[0038] This preferably occurs in interaction with the at least one first plug-in pivoting element and the at least one second plug-in pivoting element.
[0039] In an embodiment, the at least one first locking element and the at least one second locking element are arranged on the opposite side of the window as the at least one first plug-in pivot element and the at least one second plug-in pivot element.
[0040] In the design of the rail-guided vehicle, the side window can be located in the driver's cab. This creates the possibility of opening a side window in a particularly space-critical area without obstructing the operating personnel.
[0041] In the embodiment of the track-guided vehicle, it can be provided that the track-guided vehicle is a rail vehicle for passenger transport and preferably has a maximum speed of more than 250 km / h, further preferably of more than 300 km / h.
