Description
Escape Window Device for a Vehicle The invention relates to an escape window device for a vehicle according to the preamble of patent claim 1 Such escape window devices for vehicles, in particular for buses, are well known from the general prior art. Such escape window device comprises an escape window, which is pivotable relative to a structure of the vehicle between a closed position covering a corresponding window opening and an escape position uncovering the window opening.
For this purpose the escape window is designed to be pivotable about a pivot axis relative to the structure for example via a bearing device on the structure.
From the DE 202 17 925 Ui a safety window with emergency facility can be gathered to be known. The safety window has a glass pane surrounded by a rubber seat. On a side facing away from the rubber seal extends a safety thread, which is guided via diverters at one end ihwards towards the pane. By way of pulling the safety thread the rubber seal by * means of the safety thread is cut through so that the glass pane for instance can be pushed outward. Thereby a window opening is uncovered so that a passenger of the vehicle can leave the vehicle via the uncovered window opening.
S S...
Also the CN 201865510 U relates to an escape window device for a bus with a slidabte escape window. The escape window described in this document can be slided in the vertical direction of the vehicle and thereby uncover a corresponding window opening, via which a passenger of the vehicle can leave the vehicle.
It has turned out that leaving the vehicle through an uncovered window opening may be quite difficult for the passenger of the vehicle. This is the case in particular if the window opening in the vertical direction of the vehicle is positioned particularly far away from a bottom surface. For instance this may be the case if the vehicle has a great height, which occurs in particular with buses and trains.
For this reason it is the task of the present invention to provide an escape window device of the afore-mentioned kind that allows for a particularly easy leaving of the car via the uncovered window opening.
This task is solved by an escape window device for a vehicle, the escape window device having the features of patent claim 1. Advantageous embodiments with expedient and non-trivial further developments of the invention are indicated in the remaining claims.
In order to provide an escape window device for a vehicle, in particular a bus, the escape window device being of the afore-mentioned kind and aflowing for a particularly easy leaving of the vehicle via the uncovered window opening, ilis envisaged according to the present invention that on the escape window at least one step tread element is held, by means of which at least in the escape position a step tread for a person leaving the vehicle via the window opening is providable. The at least one step tread may bridge a gap distance extending in the vertical direction of the vehicle between the uncovered window pane and a bottom surface so that the person leaving the vehicle need not step directly on the bottom surface, but may first step on the step tread, which is positioned essentially closer to the window opening than is the bottom surface, and only subsequently step on the bottom surface.
* S Thereby also persons of short stature can easily leave the interior of the vehicle via the uncovered window opening and reach the bottom surface comfortably. The at least one *:" step tread in this setup allows for making an interim step so that the person leaving the vehicle does not need to overcome the entire distance between the window opening and the bottom surface at once, but rather can first traverse the smaller distance between the a...
window opening and the step tread and thereafter descend the remaining distance between the step tread and the bottom surface.
The step tread element integrated into the escape window thus serves as alighting and escape aid. As the step tread element is held on the escape window, the step tread element can be moved along with the escape window. Thereby it can be avoided that the step tread in the escape position of the escape window extends into the uncovered window opening. Thus, components extending into the uncovered window opening and impairing the leaving of the vehicle can be avoided so that the window opening in the escape position remains preferably completely unobstructed, thus allowing for an easy and unhindered escape.
Further advantages, features and details of the invention may be gathered from the following description of preferred embodiments and by referring to the drawing. The features and feature combinations previously mentioned in the description and the features and feature combinations named in the following description of the figures and/or shown in the figures alone can be used not only in the respective indicated combination, but also in any other combination or taken alone, without leaving the scope of the invention.

Fig. 1 in a schematic perspective view shows an escape window device 10 for a vehicle in the form of a bus. In a combined view with Fig. 2 frame elements 12 of the escape window device 10 can be discerned in Fig. 1. The bus comprises a structure, which is not shown in in Figs. 1 and 2. The escape window device 10 is mounted on the structure via the frame elements 12, by which a window opening 14 of the bus is bounded.
The escape window device 10 comprises an escape window 16 corresponding to the window opening 14, the escape window 16 having a frame 18 with lateral frame elements 20, 22, a bottom frame element 24, and a top frame element 26. The escape window 16 also comprises a pane 27, which for instance is made of glass, inserted into and held on the frame 18. Further, the escape window 16 has an additional bar 28, via which the * . lateral frame elements 20, 22 are connected with each other. * .
*:Ss The escape window 16 is held on the frame elements 12 via respective lateral hinges 30, * 32 and is pivotable relative to the structure and relative to the frame elements 12 between S.....
* a closed position covering the window opening 14 as shown in Fig. 1 and an uncovered position uncovering the window opening 14 as shown in Fig. 2. For this purpose the hinges 30, 32 each comprise a first hinge element 34 and a second hinge element 36.
The hinge elements 34 are attached to the lateral frame elements 20, 22, whilst the second hinge elements 36 are attached to the lateral frame elements 12. The hinge elements 34, 36 are articulated with each other via a bolt.
On the escape window 16 a step tread element 38 is held, through which in the escape position of the escape window 16 a step tread 40 is provided for a person leaving the bus via the uncovered window opening 14.
The step tread element 38 is rotationally fixed to a rod 42, which is pivot-mounted via respective jateral bearing supports 44 on the escape window 16 to pivot about a rotational axis relative to the escape window 16. Thereby, the step tread element 38 is held on the escape window 16 to shift relative to the escape window 16 between a use position providing the step tread 40 as shown in Fig. 2 and a non-use position shown in Fig. 1. In order to move the step tread element 38 from the non-use position into the use position the step tread element 38 in the present setup is pivoted upward in the vertical direction of the vehicle and inward in the transverse direction of the vehicle.
Figs. 3a and 3b illustrate the pivoting of the escape window 16 from the closed position shown in Figs. 3a and 3b into the escape position shown in Figs. 5a and 5b. In this connection the escape window 16 is pivoted by 1800 relative to the transverse direction of the vehicle outward and relative to the vertical direction of the vehicle downward.
Figs. 4a and 4b show the escape window 16 in an intermediate position, in which the escape window 16 is pivoted by 900 from the closed position into the direction of the escape position. The step tread element 38 -with reference to the dosed position -is arranged on an inner surface of the escape window 16 and is pivotable by essentially 9Q0.
Thereby, the step tread in it non-use position at least essentially extends in parallel to the pane 27 and in its use position extends at least essentially perpendicularly to the pane 27.
This alrows for the person leaving the bus via the window opening 14 to first step simply down on the step tread, and -being supported by the step -only thereafter descend * further to a bottom surface. * * *
* The frame 18, i.e. the frame elements 20, 22, 24, 26 are made of a light metal, in * particular an aluminium, in particular aluminium 6061 T5. Moreover, it may be envisaged that the frame elements 20, 22, 24, 26 are provided in the form of extruded profiles.
* The bolts connecting the hinge elements 34, 36 are preferably made of stainless steel and equipped with a Teflon coating. The Teflon coating both acts as galvanic corrosion protection and as lubricant for lubricating bearing surfaces.
The hinge elements 34, 36 for instance are made of processed stainless steel and equipped with a barrier ribbon for protection against galvanic corrosion with regard to the aluminium frame elements 20, 22, 24, 26. The rod 42 br instance is made of stainless steel and tension-mounted in the bearing supports 44.
The step tread element 38 is for example made of aluminium, in particular in the form of an aluminium cast component. Alternatively, the step tread element 36 can be made from a fibre reinforced plastic, in particular from a glass fibre reinforced plastic.
The step tread element 38 in the present case has a double function, as it both serves for providing the step tread 40 and as handling device for moving the escape window 16 from the closed position into the escape position.
If the step tread element 38 is moved from its non-use position into its use position, this also rotates the rod 42 by 90°. As is further set out in the following, the step tread element 38 is coupled to a locking device via the rod 42, wherein the locking device is displaceable between a locking position and a release position. In this connection the locking device by way of shifting the step tread element 38 is displaceable between the locking position and the release position. If the step tread element 38 is in its non-use position, the locking device is thereby moved into its locking position. In the locking position the escape window 16 is fixed in its closed position on the structure and thus cannot be pivoted into its escape position.
If the step tread element 38 is shifted from its non-use position into its use position, this involves the displacing of the locking device from the locking position into the release * position, In the release position the locking device releases the escape window 16 so that the escape window 16 can be pivoted relative to the structure from its closed position to its escape position. This allows for ensuring that the escape window 16 can be moved *0se* * into the escape position only if also the step tread element 38 is in its use position and accordingly renders the step tread 40 available for use.
As the escape window 16 is pivotable downward, its movement into the escape position is supported by the force of gravity and thus -once the locking device has been moved into the release position -occurs at least essentially of its own accord. In this connection the step tread element 38 moves along with the escape window t6 so that it does not extend into the uncovered window opening 14. Thereby components extending into the window opening 14 such as handles, locks or the like can be avoided so that the complete window opening 14 remains unobstructed and fully available to the person leaving the vehicle via the window opening 14. The frame elements 20, 22, 24, 26 in this setup are to be adapted accordingly to the attachment of the step tread element 38, of the rod 42, and the bearing supports 44, and to the stress exerted by the person stepping upon the step tread element 3ft Fig. Ga shows a further embodiment of the escape window device 10. The step tread element 38 has a through hole 46, which serves as grip opening. The person can reach through the through hole 46 and grab around the step tread element 38 to pivot it in a particularly easy way into the use position. C,
Fig. 6b shows a further embodiment of the escape window device 10. The step tread element 38 therein extends at least essentially across the major part of the width of the window opening 14 and in the present embodiment is equally as wide as the pane 27.
Thereby a particularly large surface of the step tread 40 can be realized. The escape window 16 according to Fig. 6b has a greater height than does the escape window 16 according to Fig. 6a, whereby -as can be gathered in particular from Figs. 7a and 7b -an enhanced headroom is provided. Moreover, as is shown in the following, in the respective escape window device 10 according to Figs. 6a and Sb different locking devices are employed.
Fig. 8 shows an embodiment of the escape window device 10, in which a reverse side 46 of the step tread element 38 in the use position bears against the top frame element 26.
Further, Fig. 8 demonstrates that a bottom side 50 of the step tread element 38 supported by a lip of the top frame element 26 in the use position. Thereby, a very high sturdiness of the step tread element 36 in the use position can be realized so that it can withstand even fl* * high stresses. * t * * *
* Fig. Qa shows a schematic cross-sectional view of the top frame element 26 according to * Fig. 6a, which is provided in the form of an extruded profile. Fig. 9b is a schematic cross-sectional view of the top frame element 26 according to Fig. 6b, which is equafly provided S..
* as extruded profile. *
Fig. ba represents a schematic cross-sectional view of the lateral frame elements 20, 22 according to Fig. 6a, which are provided in the form of extruded profiles. Accordingly, Fig. 1 Ob provides a schematic cross-sectional view of the lateral frame elements 20, 22 according to Fig. Sb, which are equally provided in the form of extruded profiles.
Figs. 11 to 17 illustrate the locking device of the escape window device 10 according to Fig. 6a. The locking device as a whole is designated as 52 and comprises two Lateral spur gears 54, which are rotationally fixed to the rod 42. In the present case the spur gears 54 are welded to the rod 42. The locking device 52 moreover comprises two lateral locking bolts 56, which in a partial portion of their longitudinal extension are designed as rack gears 58. The rack gears 58 have a respective cog profile, which is engaged by cogs of the respective spur gear 54.
If the step tread element 38 is pivoted between the use position and the non-use position.
this involves a rotation of the rod 42. The rod 42 in this process drives the spur gears 54, which via their coggings are engaged with respective coggings of the rack gears 58.
Thereby the locking bolts 56 during rotation of the spur gears 54 are translationally moved and in the present case shifted upwards and downwards in the vertical direction of the vehicle. This can be seen particularly well from Figs. 1 2a and 1 2b, wherein the step tread element 38 in Fig. 12a is in its non-use position and in Fig. 12b is in its use position.
The non-use position of the step tread element 38 causes the locking position of the locking device 52, in which the locking bolts 56 each are received partially in the pivotable escape window 16 and partially in a structure-fixed cross element, such as for instance in the form of the top frame element 12, bounding the window opening 14. In other words the locking bolts 56 in the locking position engage the top frame element 12 and thus lock the escape window 16.
If the step tread element 38 is pivoted into its use position, the locking bolts 56 are moved * out of engagement with the top frame element 12 so that the escape window 16 can be pivoted. This can be seen from Fig. 12b. Fig. 13 shows the locking bolt 56 engaging the top frame element 12.
* In Fig. 14 is discernible a receptacle 60 of the vehicle-fixed top frame element 12, in tee.
which the corresponding locking bolt 56 can be received in the locking position. From Fig. a C. * 15 it can be seen particularly well how the spur gears 54 engage the corresponding rack gears 58 of the locking bolts 56.
In Figs. 16 and 17 the lateral frame element 22 can be discerned, on which the corresponding locking bolt 56 is shiftably mounted relative to the frame element 22. For this purpose for instance a corresponding guidance 62 is provided. Moreover, a corresponding aperture is provided, via which the corresponding spur gear 54 can engage the rack gear 58. Further, for instance in an area 64 a recess for the bearing support 44.
Figs. 1 Ba to 24 illustrate a further embodiment of the locking device 52. The locking device 52 comprises respective lever elements 64, which on one side are rotationally fixed to the rod 42. On the other side, the lever elements 64 have guiding bolts 66, which engage corresponding guideways 68 of guiding elements 70 of the locking device 52. The * 11 locking elements 70 in this setup are attached to the lateral frame elements 12 and thus are structure-mounted.
If the step tread element 38 is pivoted between the use position and the non-use position, this causes a movement of the guiding bolts 66 along the guideways 68. The guiding bolts 66 in this setup enclosed on the outer circumference by a nylon bushing 72 in order to keepfriction and wear to a minimum.
If the step tread element 38 is in its non-use position, the lever elements 64 and with these the guiding bolts 66 are in a lower position. In this lower position the guiding bolts 66 are fixed by a respective pin 74, which is fixed to the guiding element 70 in a way translationally movable relative to same. The pin 74 exhibits a ball head 76 and is spring-loaded by a spring 78 holding it in a retaining position, in which the guiding bolts 66 are fixed in the lower position.
* I' * * * If the step tread element 38 is pivoted by a sufficiently great force from the non-use *.....
* position into the use position, the pin 74 via the respective guiding bolt 66 and its ball head 76 contrary to the spring load is pushed into a release position so that the guiding * bolts 66 can be moved from the lower position into an upper position shown in Fig. lBb.
* The respective upper position of the guiding bolts 66 in this setup corresponds with the use position of the step tread element 38. 0* *0
* Fig. 19 shows the step tread element 38 in an intermediate position, in which the step tread element 38 relative to the non-use position is pivoted by 45°. Correspondingly, also the guiding bolts 66 in the guideways 68 are in an intermediate position. The guideways 68 are designed such that by moving the guiding bolts 66 along the guideways 68 a pivoting of the escape window 16 from the closed position in the direction towards the escape position into a slightly opened intermediate position occurs, The escape window 16 is in this intermediate position, if the step tread element 38 is in its use position whilst the guiding bolts 66 are still received within the guideways 68. At this stage the escape window 16 is opened by 3.5° relative to the closing posction, The respective guideway 68 has a corresponding opening, via which the respectively corresponding guiding bolt 66 during pivoting of the escape window 16 into the escape position can be moved out of the corresponding guideway 66.
The respective opening, however, at least partially is covered by a respective leaf spring, which is attached to the structure, for instance to the lateral frame elements 12. In this connection the respective leaf spring can be attached to the corresponding guiding elements 70.
The respective leaf springs can be seen particularly well from Figs. 21a and 21b and therein bear the reference sign 75. By the leaf springs 75 the guiding bolts 66 initially are kept in the guideways 68. In order to move the guiding bolts 66 out of the guideways 68, a sufficiently great force acting outward from the car is required so that thereby the leaf springs 75 are elastically bent allowing for the guiding bolts 66 to be moved out of the guideways 68. The leaf springs 75 thus allow for a complete moving of the step tread element 38 into the use position, without the escape window 16 for instance due to the influence of gravity being moved fully into the escape position. This can be seen * ** particularly well from Fig. 24, with the guiding bolt 66 being secured by means of the leaf spring 75 against an undesired moving out of the guideway 68. Only upon a corresponding application of force to the escape window 16 and thus the guiding bolt 66 and via same to the leaf spring 75, the leaf spring 75 is correspondingly elastically bent.
Thereby it releases the opening of the guideway 68 5 that the guiding bolt 66 can be moved out of the guideway 68.
*;e Figs. 25 to 27b illustrate a further embodiment of the locking device 52. The locking device 52 accordingly comprises a lever 80, which is attached to the lateral bar element 12 and thus structure-mounted. In order to unlock the escape window 16, the lever 80 needs to be moved at least essentially in parallel to the pane 27. This movement, however, in the non-use position of the step tread element 38 is impeded by the step tread element 38, as the lever 60 in its direction of movement at least partially is covered by the step tread element 38, which is in its non-use position. The lever 80 can be moved only, if the step tread element 38 is in its use position or has been moved along a pre-definable path out of its non-use position, which can be seen particularly well from Figs. 27a and 27b. Thereby -just like it is the case with the previously described embodiments of the locking device 52-it is ensured that the escape window 16 can only be moved into the escape position, if the step tread element 38 is in its use position or has at least been moved out of its non-use position.
In the present case the lever 80 can be moved already, if the step tread element 38 has been displaced by 30° from its non-use position. If subsequently the escape window 16 is pivoted into its escape position, the influence of gravity causes a further pivoting of the step tread element 38 from its 300 position into its complete use position relative to the frame 18. * S * Ga
