Description

[0028] The invention is explained in greater detail below with reference to embodiments; in the drawings by way of example:

[0029] FIG. 1 shows an embodiment of a vehicle-body-side securing profile, a resiliently deformable intermediate member which is secured thereto and a floor-side securing profile which is connected to the intermediate member,

[0030] FIG. 2 shows the arrangement according to FIG. 1 formed from the vehicle-body-side securing profile, the intermediate member and the floor-side securing profile after installation in a vehicle body of a rail vehicle which is not illustrated in greater detail,

[0031] FIG. 3 shows the arrangement comprising the vehicle-body-side securing profile, the intermediate member and the floor-side securing profile according to FIG. 1 after assembly of an electrical heating device in a hollow chamber of the vehicle-body-side securing profile, and

[0032] FIG. 4 shows the arrangement formed from the vehicle-body-side securing profile, the intermediate member and the floor-side securing profile according to FIG. 1 after an air supply device has been connected to a hollow chamber of the vehicle-body-side securing profile.

[0033] In the figures, for the sake of clarity, the same reference symbols are always used for identical or comparable components.

[0034] FIG. 1 shows a securing profile 10 which is suitable for securing to a vehicle body wall (not shown in FIG. 1) of a vehicle body (or vehicle body shell) and is consequently referred to below as a vehicle-body-side securing profile.

[0035] The vehicle-body-side securing profile 10 is preferably an extruded profile-member whose extrusion direction or whose longitudinal direction is indicated in FIG. 1 with the reference symbol S.

[0036] The vehicle-body-side securing profile 10 has securing holes 11 which enable the securing profile 10 to be screwed to the vehicle body wall. FIG. 1 further shows a hollow chamber 12 which extends in the extrusion direction or the longitudinal direction S of the securing profile 10 and which has two end-face openings 12a. The hollow chamber 12 has in the embodiment according to FIG. 1 a closed contour.

[0037] In addition to the hollow chamber 12, the vehicle-body-side securing profile 10 is provided with a rail-like retention portion 13 which enables securing of a resiliently deformable intermediate member 20 to the securing profile 10. The deformable intermediate member 20 is preferably an extruded profile-member of rubber or plastics material, that is to say, a material with the lowest possible thermal conductivity.

[0038] The resiliently deformable intermediate member 20 is also provided with hollow chambers which are indicated in FIG. 1 with the reference symbol 21. The longitudinal direction of the hollow chambers 21 preferably extends parallel with the longitudinal direction of the hollow chamber 12 and consequently parallel with the extrusion direction or longitudinal direction S of the securing profile 10.

[0039] At the side of the resiliently deformable intermediate member 20 facing away from the vehicle-body-side securing profile 10, there is fitted a securing profile 30 which is suitable for assembly on a floor of a rail vehicle not shown in FIG. 1 and which is consequently also referred to below as a floor-side securing profile 30.

[0040] In order to secure the floor-side securing profile 30, there are provided securing holes 31 which enable the securing profile 30 to be screwed to the floor.

[0041] In order to secure the floor-side securing profile 30 to the resiliently deformable intermediate member 20, there is provided a rail-like retention portion 32 which in terms of its shape may correspond to the rail-like retention portion 13 of the vehicle-body-side securing profile 10.

[0042] The floor-side securing profile 30 is also preferably an extruded profile-member; the longitudinal direction or extrusion direction of the floor-side securing profile 30 preferably extends parallel with the longitudinal direction S or extrusion direction of the vehicle-body-side securing profile 10.

[0043] FIG. 2 shows the arrangement according to FIG. 1 formed from the vehicle-body-side securing profile 10, the resiliently deformable intermediate member 20 and the floor-side securing profile 30 after assembly in a vehicle body (or a vehicle body shell) 40 of a rail vehicle 50. The vehicle-body-side securing profile 10 is screwed to the vehicle body wall 41 of the vehicle body 40 by means of securing screws.

[0044] The floor-side securing profile 30 is securely screwed to a floor 60 of the rail vehicle by means of securing screws.

[0045] The resiliently deformable intermediate member 20 which is located between the two securing profiles 10 and 30 and which is retained thereby consequently separates the floor 60 at the edge side from the vehicle body wall 41 so that the floor 60 can move relative to the vehicle body wall 41, for example, in the event of temperature fluctuations and the different thermal expansion or thermal contraction of the materials which occurs with different thermal coefficients.

[0046] In order to ensure safety of access in the transition region between the floor 60 and the vehicle body wall 41, the region of the resiliently deformable intermediate member 20 in the embodiment according to FIG. 2 is covered with a covering profile 70. The covering profile 70 is fixed at the vehicle-body-side and, for example, screwed to the vehicle body wall 41 of the vehicle 40. At the floor side, the covering profile 70 is not fixed, but is instead positioned in a displaceable manner on the floor 60. If, in the event of temperature fluctuations, there is a relative movement of the floor 60 relative to the vehicle body wall 41 and consequently an expansion or compression of the resiliently deformable intermediate member 20, the covering profile 70 will be able to move on the floor 60 so that the covering profile 70 does not counteract or prevent the relative movement of the floor 60 relative to the vehicle body wall 41.

[0047] In order to ensure good thermal insulation between the inner space of the vehicle 50 and the portion below the resiliently deformable intermediate member 20, the intermediate member 20, as already mentioned, is preferably provided with the hollow chambers 21 since these considerably increase the thermal insulation of the intermediate member 20.

[0048] The hollow chamber 12 of the vehicle-body-side securing profile 10 can be used to heat the securing profile 10 and the covering profile 70 in order to prevent a slippery formation on the covering profile 70 in winter and to reduce the risk of accidents. Embodiments of how the hollow chamber 12 can be heated are explained in greater detail below in relation to FIGS. 3 and 4.

[0049] FIG. 3 shows the arrangement comprising the vehicle-body-side securing profile 10, the resiliently deformable intermediate member 20 and the floor-side securing profile 30 according to FIG. 1 after an electrical heating device has been pushed into the hollow chamber 12 of the securing profile 10 in the longitudinal direction S. The electrical heating device 100 preferably extends over the entire lengthwhen viewed in the longitudinal direction Sof the hollow chamber 12 or over the entire length of the securing profile 10 in the longitudinal direction S.

[0050] With a view to simple electrical contacting of the electrical heating device 100, it is considered to be advantageous for electrical connections 110 of the heating device 100 to be guided out of the securing profile 10 at an end-face opening 12a of the hollow chamber 12.

[0051] In the embodiment according to FIG. 3, the hollow chamber 12 of the securing profile 10 serves to retain or carry the electrical heating device 100. In order to ensure this function, it is not absolutely necessary for the hollow chamber 12 to have a closed contour; the contour of the hollow chamber 12 has to be suitable only for retaining the heating device 100. Slots or the like in the contour of the hollow chamber 12 are non-critical as long as the retention function of the hollow chamber 12 remains ensured.

[0052] In the embodiment according to FIG. 3, the hollow chamber 12 or the vehicle-body-side securing profile 10 is thus heated in an electrical manner in order to heat the covering profile which is illustrated in FIG. 2 and which is located above the intermediate member 20 and to protect it from frost.

[0053] FIG. 4 shows an embodiment in which the arrangement according to FIG. 1 formed from the vehicle-body-side securing profile 10, the resiliently deformable intermediate member 20 and the floor-side securing profile 30 has been provided with a supply device 200 for supplying warm air L. The supply device 200 comprises a hose 210 which is connected to the end-face opening 12a of the hollow chamber 12 and which connects the hollow chamber 12 to an air channel 220 of the supply device 200. The air channel 220 may be fitted as a separate component to the vehicle body wall 41 according to FIG. 1 or may form an integral component of the vehicle body wall 41. For example, the air channel 220 may be formed by an extruded profile portion of a vehicle-body-side extruded profile-member of the vehicle body 40.

[0054] The air channel 220 is connected to a fan 230 and a heating device 240 which are illustrated only schematically in FIG. 4.

[0055] If, in the case of low temperatures, for example, during winter, a slippery formation in the region of the covering profile 70 according to FIG. 2 is intended to be prevented, the hollow chamber 12 and consequently the vehicle-body-side securing profile 10 can be heated by hot air being supplied to the hollow chamber 12 by the fan 230 and the heating device 240 through the vehicle-body-side air channel 220 and the hose 210. In the embodiment according to FIG. 4, the vehicle-body-side securing profile 10 and the covering profile 70 according to FIG. 2 are therefore heated by a fluid in the form of gas which is directed through the hollow chamber 12. The hollow chamber 12 consequently performs the function of a fluid line.

[0056] In the embodiment according to FIG. 4, the hollow chamber 12 itself acts as a fluid line; alternatively, it is possible inside the hollow chamber 12 to provide a fluid hose which takes over directly the fluid line. In such a case, it is not necessary for the profile of the hollow chamber 12 or the contour of the hollow chamber 12 to be completely closed; instead, it is sufficient for the profile or the outer contour of the hollow chamber 12 to be suitable for retaining the fluid line. Slots, gaps or other openings in the hollow chamber profile 12 are consequently non-critical when a separate fluid line is provided.

[0057] Although the invention has been illustrated and described in greater detail by preferred embodiments, the invention is not limited by the disclosed examples and other variations can be derived therefrom by the person skilled in the art without departing from the protective scope of the invention.
