Description

A wheel-supported house
The invention relates to a wheel-supported house of the type that is seen in the preamble of claim 1.
The house is in the form of a trailer, a semitrailer or a motor vehicle carrying the house.
The wheel-supported house is of the type that has a chassis having one or more wheels, which carries a house comprising a substantially vertical wall having a substantially rectangular wall opening that has a substantially horizontal opening edge, and a box that is displaceably received in the opening and comprises a bottom wall, which extends in the vertical plane and the size of which substantially corresponds to the wall opening of the house, the box having side walls connecting to the edge area of the bottom wall, which side walls are adja¬ cent, with a minor play, to the edges of the wall opening and are perpendicular to the bottom wall.
A wheel-supported house of such a kind is previously known. In that connection, a telescopic beam directed parallel to the displacement direction of the box and situated above a trans- versally central area of the box has been mounted in an over- head position on an own supporting structure. The telescopic beam comprises a stationary horizontally directed straight outer pipe joint, and an inner beam part displaceably received and displaceable therein, the outer free end of which is con¬ nected to the longitudinally central area of the upper edge of the bottom wall of the box. Furthermore, there is a driving mechanism provided, which acts between the two telescopic beam parts. Backing rollers are arranged, on one hand on the floor for the support of the lower horizontal wall of the box, and on the other hand on the side edges of the wall opening. The need of an own supporting structure implies increased costs and increased total weight of the construction. The lat¬ ter circumstance is a particular drawback if the increase in weight means that the driving licence requirement increases for a class of a vehicle (lorry, trailer) carrying the house. The telescopic beam has no rigid connection to the box. The tendency of the box to turn around the connection of the tele¬ scopic beam to the box under the impact of the gravity is counteracted by the support via the rollers on the floor and on the side edges of the wall opening. By the fact that the telescopic beam is situated approximately halfway between the vertical side walls of the box, the telescopic beam occupies a relatively great part of the space defined by the box in the pushed-out state thereof. The telescopic beam has a relatively large kinetic friction and requires a displacement mechanism.
Therefore, an object of the invention is to provide a wheel- supported house of the initially mentioned nature, in which the mentioned drawbacks are entirely or partly obviated.
The object is attained by the invention.
The invention is defined in the appended independent claim.
Embodiments of the invention are defined in the appended dependent claims.
Fig . 1 shows schematically a vertical section through a wheel-supported house according to the invention. F Fiigg.. 2 2 shows schematically a section taken along the line H-II in Fig. 1.
Fig . 3 shows an enlarged view of a detail in Fig. 1.
Fig . 4 shows a schematic section taken along the line IV-IV in Fig. 1. Fig. 5 shows an alternative embodiment of the wheel-sup¬ ported carriage in a view corresponding to Fig. 4. Fig. 6 shows a view taken along the line VI-VI in Fig. 5.
Figs. 1 and 2 show a wheel-supported vehicle 1 having wheels 2 that carries a house 3 that has at least one door (not shown) that permits passage into and out of the house 3. The house 3 has a roof 31 and a floor 32, which are shown substantially horizontal and side walls 33-36. In Fig. 2, the driver's cab 11 of the vehicle 1 is illustrated schematically.
The wall 34 of the house 3 has a substantially rectangular opening 4 having a horizontal upper edge 41 and lower edge 42, as well as vertical edges 43-44. In the opening 4, a box 6 is shown received. The box β comprises a bottom wall 61 that is substantially rectangular. Near the circumference of the bot¬ tom wall 61, side walls 62-65 are connected that are mutually perpendicular and perpendicular to the bottom wall 61. The walls 62-65 are adjacent, with a minor play, to the edges 41,43,42 and 44, respectively, of the opening 4. The bottom wall 61 of the box has a flange 66 that, around the circumfer¬ ence of the bottom wall 61, projects past the circumference of the tubular part of the box 6 formed by the walls 62-65. The circumferential flange 66 serves to abut against the edge por- tion of the wall 34 that is adjacent to the opening 4, in order to present a seal in the inserted state of the box 6.
The walls 62-65 are provided with a circumferential flange 67 at the free edges thereof, which flange forms a stop against the edge portion of the wall 34 that most closely surrounds the opening 4. Thus, the flange 67 limits the protrusion of the box 6 out of the house 3. Two supporting beams 8 extend substantially horizontal between the wall 34 and an opposite wall 35 and are rigidly fixed or integrated in said walls. The house 3 may be in the form of a self-supporting shell struc- ture, wherein the walls 31-36 are integratedly connected to each other and may consist of parallel, spaced-apart surface layers that are united to an intermediate spacer layer. The surface layers may consist of fibre-reinforced plastics or of metal, and the foam layer may consist of, for instance, foamed plastic.
The beams 8 are mutually parallel and perpendicular to the plane of the opening 4. The beams 8 are also parallel to the walls 62-65 of the box.
The beams 8 are rigid in the vertical plane and carry a car¬ riage 72 each. The carriage 72 is provided with a protruding supporting arm 73 that extends into the box 6 next to a wall 63, 65, respectively, and is attached to the same for the establishment of a rigid connection in the vertical plane. The supporting arm 73 is preferably located vertically below the beam 8, but a certain mutual lateral displacement is allowed and the carriage 72 has a torsion-resistant support on the beam 8, and the beam 8 is torsion resistant around the longi¬ tudinal axis thereof and is rigidly connected to the opposite house walls 34,35.
The carriage 72 may be shaped to present a sliding along the beam 8, but preferably, the carriage 72 has spaced-apart wheels along the beam 8 on the top side and the bottom side of a lower flange 7 on the beam 8, in order to present a torque- resistant connection in the vertical plane between the car¬ riage 72 and the beam 8 in order to carry the box 6, by means of the supporting arm 73, in a constant orientation during the displacement thereof in a direction parallel to the direction of the beams 8.
In Fig. 1, the wheels 75 of the carriage 72 are illustrated schematically. In Fig. 2, it is seen how the beams 8 extend in vertical plane near the side walls 63, 65 of the box and that the supporting arms 73 extend parallel to and are located at the box walls 63, 65. The supporting arms 73 may be integrated in the walls 63, 65, and extend into these walls between the two main sur¬ faces thereof.
As is seen in Fig. 3, the opening edge 42 of the wall 34 may be provided with a rotatably mounted roller 15 that by an upper portion of the envelope surface thereof protrudes above the opening edge 42 in order to support the wall 64 of the box rollingly. Furthermore, the wall 34 is shown to have an inter¬ nally horizontally protruding bolt 54 that extends through an opening 68 in the flange 67. A nut 55 is shown mounted on the outer end of the threaded bolt 54 in order to keep the flange 67 in contact with the wall 34 in the extended state of the box 6. Correspondingly, a bolt may extend outward from the outside of the wall 4 through an opening in the flange 66 in order to allow the flange 66 to be held in contact against the wall 42 by means of a nut on the outer end of the bolt, in the retracted state of the box 6. Two or more such locking members may be distributed along the bottom edge of the box.
In Fig. 4, it is seen how the upper wall of the house is inte- gratedly connected to the beam 8. The beam 8 is horizontally directed and extends in the vertical plane and is provided with a horizontally extended lower flange 7, which forms a tread for carriage wheels 75, which are rotatably mounted in the carriage 72.
The beam 8 may, as well as the walls of the house, consist of two spaced-apart stiff surface layers with intermediate spacer material, the surface layer of the beam suitably being inte¬ grated in the lower surface layer of the roof 31 as well as in the internal surface layer of the side walls 34, 35. In an alternative embodiment according to Figs. 5 and 6, the carriages 72 may be in the shape of a C-profile that runs across a line of rollers 75, which are carried on the beam 8.
The arrangement shown in Fig. 3 having a bolt that extends through an opening in the flange 61 and that, by means of a nut 55, locks the lower part of the flange 67 to the wall 4, constitutes a releasable locking member for securing the box in the end-displacement position thereof. A person skilled in the art appreciates that the locking member may be imparted other embodiments.
