Abstract

A pivoting door assembly comprises a main frame 1 and a panel 2 hinged to it and is installed in a door opening bounded by body members 3. The assembly is aligned in the opening with regard to height and width, being retained in position by means of spacing elements 5; the frame 1 and body members 3 are then secured to each other by means of a permanently elastic adhesive 7. A filler strip 8 (Fig. 2) may be used to reduce the adhesive required and tacking bolts 6 may be used temporarily during installation.

Description

The invention relates to a method, of fastening and sealing a hinged door in a vehicle, particularly a rail vehicle, where the hinged door is formed by the door frame and the door· leaf hinged thereto and the y vehicle has a door opening bounded on all sides by door pillars. . ' In rail vehicles it is known for the door frame of a hinged door to be welded into the door opening.

For this purpose the first requisite is that the door ,frame should be able to be inserted into the door opening without play and without forcing. To achieve this is, however, very expensive, because the welding of the door pillars to the body framework and to the panels gives rise to welding distortion, which has to be put IS right by mechanical working of tlie door pillars. If the interior dimensions of the door opening now correspond to the external dimensions of the hinged door, the latter is inserted and the door frame is welded to the door pillars. This results in further welding ze distortion, so that in order to make the door leaf capable of operating, the door frame requires mechanical working. When a hinged door is replaced, for example after damage in the door region resulting from an accident, additional difficulties occur in the removal is of the damaged hinged door and the straightening of ' the door pillars. When a hinged door is secured in position by riveting or bolting, it is necessary for the door frame and the door pillars to be differently shaped in order to obtain an accessible connection point, g and this is in some cases impossible, particularly in the bottom region of the door because of the outer longitudinal members of the underframe. In addition it has been found that with this type of fastening complete sealing against the penetration of moisture i0 from outside is not possible. Because of the rigid connection cf the hinged door to the vehicle body, both in the case of a welded connection and in the case of a rivet or bolt connection, all torsion, for example that occurring when travelling over points, is transmitted to the hinged door, which is detrimental not only to the connection but also to the sealing between door frame and door leaf.

The problem underlying the invention is to provide a method of fitting a hinged door, wherein zo tolerances in the manufacture of the hinged door and of the door opening are disregarded, the door frame is installed without stress, and the hinged door is not affected by torsion of the vehicle body.

This problem is solved when, after the ZS hinged door has been vertically and laterally aligned in the door opening in the vehiclq it is secured by spacer elements, and the permanent connection between the door frame and the door opening is made by means of a permanently elastic .adhesive.

The course of the process is illustrated diagrammatically with the aid of one exemplary §· embodiment in. the drawings, in which: Figure 1 shows the hinged door vertically and laterally aligned by spacer elements in the door opening, and Figure 2 shows the hinged door in the installed condition.

The hinged door consists of the door frame i and the door leaf 2, which are joined together by hinges. In order to receive the hinged door, the vehicle has a door opening which is hounded hy horizontal and vertical /s' door pillars 5, which are welded- to the body framework and/or to the· panelling 4. Since the dimensions of the door opening are selected to be about 20 mm larger than those of the hinged door, slight deviations of the door pillar from the horizontal or vertical or any 2^) welding distortion are of no concern, provided that the hinged door can still be inserted without forcing.

The hinged door inserted into the door opening is first aligned with the aid of spacer elements 5 in such a manner that the door frame 1 is in the predeterm25 ined position and the door leaf 2 is in line with the panelling 4. In order to relieve the bottom spacer ele ments of the weight of the hinged door, tack screws 6 can be inserted at the side and top in the region of the - 4 spacer elements 5» in order to join the door frame 1 to the door pillars 3 in such a manner that movement between these is impossible (Figure 1).

After the hinged door has now been fastened in S the door opening, the space between the door pillars and the door frame 1 is now filled with a permanently elastic adhesive 7 in the region between the spacer elements 5· After this adhesive has hardened, the spacer elements 5 and tack screws 6 are removed, and the le resulting openings are likewise filled with the permanently elastic adhesive 7· In order to reduce the time required for the hardening of the adhesive 7, a filler 8 in strip form, for example a strip of foamed plastics material, is inserted centrally iff between the door pillars 3 and the door frame 1, as also shown in Figure 2, and on both sidesof this strip the space between the door pillars 3 and the door frame 1 is then filled with the adhesive 7· It is also possible, since the spacer elements 5 are not 3J> fixedly joined to the door pillars 3 and the doorframe 1, to remove only the tack screws 6 after the adhesive 7 has heen applied and has hardened, so that the spacer elements 5 form a part of the filler S.

Since the adhesive 7 adheres only to metal 25' parts, hut otherwise has a certain elasticity, and since the filler 8 is not joined to the metal parts, an elastic connection exists between the door frame 1 and the door pillars 3 and has the effect that the hinged door is not affected by torsion of the vehicle body.

In the event of an accident in the door region, the permanently elastic adhesive 7 is cut out and the hinged door is removed. After the vehicle body and the door pillar 5 have been straightened, a new hinged door can then be installed in the manner described above.

Claims
