Definitions

  • the present invention relates to a motorhome having a vehicle longitudinal axis and a superstructure that is arranged on a vehicle chassis and extends with the vehicle longitudinal axis and has at least one space expansion module that is displaceably attached to the superstructure transverse to the vehicle longitudinal axis and extends at least approximately over the entire length and height of a longitudinal side of the superstructure.
  • motorhomes are known per se.
  • motorhomes are meant to be motorized vehicles such as for example mobile homes or caravans, but also non-motorized vehicles such as for example trailers and house trailers, respectively.
  • motorhomes it doesn't basically matter for which purpose the motorhomes are employed. It is only important that they have a superstructure that puts up an interior that is suitable for the permanent residence of persons. It doesn't basically matter for the significance of the invention whether the motorhome is employed for long travels or very short travels—for example in a city. Nevertheless, the invention substantially relates to vehicles that are employed for tourism purposes, since here the benefit of the invention takes effect to a significantly large extent.
  • the invention also makes sense in motorhomes that are used in the non-tourism use such as for example the building and showman trade, delivery vehicles, e.g. for traveling food shops, or also for the use for medical application purposes, for example a medical blood transfusion service. It is also conceivably to use the motorhomes according to the invention as mobile operation centers, especially for military or police operations.
  • vehicle longitudinal axis in this context has to be understood as the axis extending substantially through the front end and the rear end of the motorhome, preferably through the center of the front end and the center of the rear end. That is, the longitudinal axis extends in parallel to the traveling direction in which the motorhome is typically moved.
  • the motorhome according to the invention over the initially described motorhomes is characterized in that a part of the furnishing in the superstructure of the at least one space expansion module is arranged such that at least a quarter, preferably a third of the gross volume of the furnishing of the superstructure is attached to the at least one space expansion module.
  • furnishing is broad to understand here. In the meaning of the invention this shall include all what is arranged in the superstructure and attached there for permanent whereabouts. That is, these are especially all fittings that do not contribute to shroud the interior to the outside, i.e. especially not the walls, the floor, and/or the roof of the superstructure. So, under the term furnishing there fall especially kitchen furniture, seating furniture, reclining furniture, beds, cupboards, tables but also wet spaces, shower cabins, toilet cabins, garages, storage boxes etc. that are attached to the superstructure.
  • gross volume in the meaning of the invention should be understood as meaning that it is the product of the base surface of the furnishing multiplied with the maximum height of the furnishing.
  • base surface should be understood as meaning the surface corresponding to the projection surface of the furnishing seen from the vertical.
  • volume can also be obtained from the sum of partial volumes of individual furniture and parts of the furnishing.
  • the inventive idea underlying the invention is based on the findings that just the problems that have always been feared with the drives or the statics of the slideouts can be solved with less interventions in the usability of the superstructure than the use of various slideouts regarding the usability of the superstructure do involve.
  • the slideout generally cannot extend completely over the entire length of the superstructure, because the stationary part of the superstructure needs a certain constructive thickness at its edges.
  • the phrase at least approximately over the entire length of a longitudinal side of the superstructure should be understood as meaning the whole side surface of the superstructure less a possible edge constitution of the stationary part of the superstructure.
  • the term can also refer to a maximum available length of a longitudinal side of the superstructure.
  • the interior formed in the superstructure is only formed in a section along the vehicle longitudinal axis due to the presence of a motor and/or a cooling facility in the rear of the vehicle. In this and in a general case there is meant the longitudinal side of the superstructure less the length along which there is not formed living space in the interior.
  • the at least one space expansion module further has at least one height that corresponds to at least the 0.8-fold of the maximum headroom of the interior of the superstructure.
  • the headroom refers to the distance between floor and ceiling of the interior; but not to the height obtained for example in places with a dome light or other extensions or fittings formed on the ceiling or the floor.
  • the superstructure has a first space expansion module and a second space expansion module arranged opposite thereto.
  • both respectively extend approximately over the entire length and height of a longitudinal side of the superstructure, wherein a part of the furnishing of the superstructure is arranged in both space expansion modules such that at least two thirds of the gross volume of the furnishing of the superstructure are attached to both space expansion modules.
  • the furnishing of the superstructure is designed and/or arranged such that a passageway to the at least one of a kitchen, shower, toilet, bed and/or bath arranged in the superstructure remains free from furnishing, if the one or all the space expansion modules are completely displaced in the superstructure.
  • a minimum of accessibility to the present pieces of furniture is maintained. So, the motorhome at least in parts like a conventional motorhome without slideout remains well usable also while driving or in a state with retracted space expansion modules.
  • At least one space expansion module has a maximum depth corresponding to the maximum depth of a kitchen furniture, a bed, and/or a seating furniture. In this way it can be achieved that no step or no projection is present on the floor between the space expansion module and the superstructure that could optically or ergonomically be disadvantageous.
  • At least one space expansion module has a maximum depth that is smaller than the half of the width of the superstructure.
  • Such an arrangement especially permits that the space expansion modules can be arranged opposite to each other such that they each have the same depth and at worst each occupy approximately the half of the available width of the superstructure. Accordingly, with such a development almost a doubling of the usable living space can be achieved with largely balanced statics at the same time.
  • two space expansion modules arranged opposite in the superstructure are configured such that the sum of the depths of both opposite space expansion modules is smaller than the interior width of the superstructure less a pass-through width preferably of at least 50 cm in width.
  • a further advantage is that it is possible to attach at least partially parts of the furnishing to the superstructure and/or to the vehicle chassis in this area.
  • these may be for example seating furniture with passenger restraint systems.
  • At least one piece of furniture is arranged and configured such that it can be extended and/or displaced transverse to the vehicle longitudinal axis such that it extends at least partially into a space expansion module.
  • an entry and at least one climbing assistance, kitchen units, a refrigerator, a closet, a bathroom, a toilet, and/or a bed are arranged in or on the first space expansion module.
  • a wet space can be arranged that includes either of them or both components.
  • a shower shall be subsumable under the term wet space.
  • a wet space is substantially understood to be a single piece of furniture due to its typically modular, complete design.
  • a wet space comprises at least a water supply and a water discharge device as well as a substantially waterproof sealable wall of the wet space.
  • kitchen units in this context gears to at least one kitchen cupboard and/or a worktop, e.g. with a sink unit and/or a hotplate.
  • the kitchen units can also contain further components, in particular a refrigerator, an oven, a water tank, a boiler, a dishwasher, a washing machine, or a waste bin.

  • a water tank a boiler
  • a dishwasher a washing machine
  • a waste bin a waste bin
  • the second space expansion module a closet and at least one seating furniture, a bathroom, a toilet, and/or a bed are arranged.
  • a closet and at least one seating furniture, a bathroom, a toilet, and/or a bed are arranged.
  • Such a combination of the mentioned objects in the second space expansion module also has proved to be a particularly advantageous functional combination of large parts of the furnishing.
  • the motorhome has at least one bed in a space expansion module that is arranged such that it extends in parallel to the vehicle longitudinal axis in its longitudinal direction and is preferably engineered such that it can be extended transverse to the vehicle longitudinal axis.
  • the bed in an extended position of the space expansion modules forms the full lying surface, whereby for example an extended aisle or space for further furniture can be achieved.
  • the bed in its longitudinal direction can also be arranged transverse to the vehicle longitudinal axis in a space expansion module and preferably engineered such that it can be extended transverse to the vehicle longitudinal axis.
  • a not extendable bed in a space expansion module such that it extends transverse to the vehicle longitudinal axis in its longitudinal direction.
  • the bed for example in a retracted position of the at least one space expansion module can almost completely extend over the entire width of the vehicle chassis, wherein only in the extended state of the space expansion module an aisle of the vehicle longitudinal axis is formed.
  • a bed is understood to be a place to sleep for at least one person, but it is also conceivable that the bed is engineered as a double bed, a bunk bed, or a stretcher, with and without a facility for fixing persons.
  • a bed is arranged in the non-displaceable part of the superstructure such that it extends in parallel to the vehicle longitudinal axis in its longitudinal direction. Then, the bed is extended transverse to the vehicle longitudinal axis, but not transverse to the body axis of the resting person, but in parallel thereto. This reduces disturbing gaps in the lying surface.
  • a bench is arranged and configured such that this is at least partially pivotable about a horizontal pivot axis.
  • This arrangement is that in the extended state of the at least one space expansion module (slideout) either a gain in usable living space can be obtained, or the space extended transverse to the vehicle longitudinal axis can be used as an extended seating.
  • the bench is attached to the floor and/or to the wall of the space expansion module via movable attachment elements such that a back and/or a seat are pivotable from a seating position to an upright storage position.

  • attachment elements prefferably configured as a lever structure such that the seat and/or the back are pivotable to the seating position by simply manually operating an operating facility, wherein preferably also the back is pivoted to an inclined position.
  • a seat belt anchorage is attached to a supporting member of the motorhome to which at least one restraint system for at least one passenger is arranged. So, the seating furniture can be used as passenger seat while driving.
  • a dinette is arranged in the non-displaceable part of the superstructure of the motorhome that in its longitudinal axis extends transverse to the vehicle longitudinal axis that is preferably configured displaceable, pivotable and/or height-adjustable.
  • the term dinette especially gears to a group of furniture comprising at least one piece of seating furniture that is arranged beside and/or at least partially around a table.
  • the seating furniture and/or the table can be configured adjustable, displaceable, and/or foldable such that a seat with table, a seat without a table, or a lying surface can be generated.
  • the tabletop can be lowered so that an upholstered seat back of the dinette arranged thereon is flush with a seat and serves as an extension of an additional lying surface. In this way a further large additional lying surface can be created in a simple manner.
  • a storage box accessible from the outside is arranged in one space expansion module of the motorhome, preferably under a bed.
  • the term storage box is meant to be broad. This can be an arbitrary storage space. So, it is also understood to mean a garage for a vehicle, for example a small car, a bicycle, or a jet ski, or a snowmobile.
  • a garage can be configured such that an access to the storage box is only possible in an extended state of the space expansion module.
  • it is also possible to design the storage box or the garage such that parking in and out is possible both in the retracted and the extended state of the space expansion module.
  • At least one wall element is arranged that is at least telescopic, rollable, foldable and/or pivotable with respect to its width and which is preferably attached to the superstructure such that it can be pivoted at least in two parts about a vertical pivot axis.
  • the wall element can preferably be formed transverse to the vehicle longitudinal axis and completely or partially extend over the entire cross section of the motorhome.
  • the wall element has a stationary part that is preferably configured as a load-dissipating reinforcement and then also dissipates the loads from the roof into the floor of the superstructure and/or the space expansion module.
  • the stationary part can be configured as a shutter box in which a type of jalousie is rotatably arranged about a vertical axis as a rollable part of the wall element.
  • a floor-to-ceiling closet can be arranged in the superstructure and/or in the space expansion module as the load-dissipating reinforcement such that the self-supporting total length of the roof is reduced. So, the self-supporting length can be halved or divided several times.
  • the additional reinforcement results in that the roof of a space expansion module does not give away to the pressure of an inflatable seal. In this way, tightness is improved.
  • a bed configured as a double bed is arranged, wherein the bed is preferably arranged symmetrically to the vehicle longitudinal axis and in the rear part of the superstructure in the direction of travel of the motorhome.
  • the double bed can be used both in the retracted and in the extended state of the space expansion modules.
  • the bed configured as a double bed is configured such that it protrudes at least partially into at least one space expansion module when this is completely pushed into the superstructure or when the space expansion modules are pushed into the superstructure. So, even with a relatively broad bed there still results a good use of space.
  • a bathroom is arranged in the non-displaceable part of the superstructure of the motorhome, wherein the bathroom is preferably arranged symmetrically to the vehicle longitudinal axis and in the rear part of the superstructure in the direction of travel of the motorhome.
  • At least a refrigerator, a sink and a cooker are arranged in the kitchen unit of the motorhome.
  • These objects constitute the core elements of what is commonly referred to as the kitchen.
  • At least one space expansion module has at least one movably, displaceably and/or telescopically configured supply and/or disposal line.
  • supply and/or disposal line particularly gears to water-supply lines, gas-supply lines, and/or electric lines.
  • At least one space expansion module of the motorhome has at least one supply and/or disposal line that is arranged such that it extends at least in the area of a floor of the space expansion module outside the space expansion module.
  • the arrangement of the supply and/or disposal line outside the space expansion module makes it possible to arrange the line without disturbing the interior, but also to maintain the supply and/or disposal line in a simple manner.
  • At least one space expansion module has a tank.
  • the term tank gears to a storage container for stocking up solid, liquid, and/or gaseous media.
  • the tank can arbitrarily be attached to, in, on, or under the space expansion module.
  • the climbing assistance can have a step-, ramp- and/or ladder-like structure that is movably and/or stationary arranged on or in the motorhome.
  • the climbing assistance is arranged below a door or an access opening to the interior of the superstructure, whereby it is possible to enter or leave the interior of the motorhome via the first space expansion module.
  • At least one sliding bearing for slidingly supporting the space expansion module is arranged between the stationary part of the superstructure and a space expansion module that preferably has a sliding member of a sliding material, especially PTFE, that interacts with an opposite sliding surface.
  • the sliding material is understood to be a material that in combination with the sliding surface causes a reduction in friction.
  • the sliding surface advantageously is made of an abrasion-resistant material, in particular a metallic material. It is particularly advantageous to configure the sliding surface of stainless steel that is weather-resistant and ensures a permanently abrasion-resistant sliding surface.
  • the sliding member can be configured as a rolling member that rolls on the sliding surface.
  • At least one roller bearing for supporting the space expansion module is arranged between the stationary part of the superstructure and a space expansion module.
  • the underlying floor of the stationary part of the superstructure is treated with care by the rolling.
  • this configuration of the bearing makes sense.
  • it is suitable to distribute the pressure if possible along the whole edge of the space expansion module. This can be done with a very broad but also with at lot of small rollers. It is also practical to match a property of the material of the roller (e.g. hard or soft roller) to the floor conditions of the floor of the stationary part of the superstructure. This with the aim to avoid dents or running marks in the floor as far as possible.
  • At least a sliding bearing and/or a roller bearing are arranged on the space expansion module and/or the stationary part of the superstructure in the area of a load-dissipating reinforcement. This is suitably close to the inner edge of the space expansion module. It is also useable that they dissipate the loads to suitable running surfaces on the floor and/or the roof of the superstructure.

  • the seal and/or the mudguard are arranged in a reinforcement profile that preferably has at least one abutment for a force transmission means.
  • the reinforcement profile causes a stiffening of the roof of the superstructure. This has the effect that the seal fits better between the stationary part of the superstructure and the space expansion module. This applies all the more if an inflatable seal is used.
  • the force transmission means is to lock the space expansion module in the retracted and/or extended state on the stationary part of the superstructure. It can be configured as a profile having an angular edge that is attached outside of and/or inside the wall and/or the roof of the space expansion module and preferably narrow. Also, it can positively be engaged with the reinforcement profile in a receiving area.
  • the reinforcement profile has an attachment option for possible roof extension such as for example a rollable awning.
  • At least one drive for moving at least one space expansion module transverse to the vehicle axis is arranged at the superstructure and/or at a space expansion module.
  • the drive mechanically, but also hydraulically, pneumatically, or electrically driven drives can be used.
  • spindle drive has the advantage that it requires little installation space and enables an effective transduction of a rotatory movement of a drive shaft, for example an electric motor, into a translatory movement for laterally displacement of the space expansion modules.
  • a further particular advantage of spindle drives is the high holding forces that can be absorbed in the direction of the spindle longitudinal axis. Independent of the deflection position of the spindle drive thus, it can be ensured that such forces can be transferred via the toothing of the spindle drive without a relative motion between spindle and the stationary part of the drive being ensued. This is particularly advantageous with high loadings of the space expansion modules.
  • the drive can arrest the retracted space expansion modules in the stationary part of the superstructure without an additional locking device. By the high holding force also very high acceleration forces as could occur with extreme cornering can safely be absorbed. All in all, the space expansion modules with spindle drives are simply, unambiguously, and safely locked in the stationary part of the superstructure.
  • first and the second space expansion modules symmetrically to the vehicle longitudinal axis in the superstructure.
  • the term symmetrically to the vehicle longitudinal axis substantially refers to the depth of the space expansion modules. Accordingly, it is not mandatory that the space expansion modules that are symmetrically arranged to the vehicle longitudinal axis in the superstructure as such are configured in mirror symmetry to each other. The extension of the space expansion module in height and length of the lateral surface of the motorhome can be different.
  • At least one drive to the superstructure that is symmetrically to the vehicle longitudinal axis and configured such that it can move two space expansion modules at the same time transverse to the vehicle longitudinal axis.

  • four drives in total are present in the immobile part of the superstructure in the corners of two opposite space expansion modules that are mirror-symmetrically to a vertical vehicle center axis. According to this development said drive permits a simultaneous or sequential force application into the opposite corners of two space expansion modules.

  • a drive 41 is provided that is configured as a spindle drive in the case shown.
  • the relative movement of the space expansion modules 5 and 6 takes place via guiding elements 42 that are displaceably connected to the stationary part of the superstructure 4 .
  • the drive 41 and the guiding elements 42 are configured as an assembly that is arranged in the interior of the superstructure 4 .
  • FIG. 12 again shows an enlarged partial illustration of the view according to FIG. 9.1 .
  • the two areas A and B but in a sectional plane that additionally depicts the drive 41 .
  • the drive 41 is configured as a spindle drive that is attached to a drive seat 43 on the stationary part of the superstructure.
  • the drive 41 comprises an electric motor 44 that moves a spindle 46 via a transmission unit 45 .
  • the spindle 46 together with a guide tube 47 forms a telescopic lance 48 that is attached to the space expansion module 5 by means of an anchoring sheet 49 .
  • the drive 41 is configured in a corner of the superstructure 4 , whereby the loss of space by the described components for retracting and extending the space expansion module 5 is kept to a minimum.
  • FIG. 13 shows the identical area of the superstructure as FIG. 12 , but with the extended space expansion module 5 .
  • This illustration particularly explains how the spindle 46 together with the guide tube 47 forms the telescopic lance 48 .
  • the spindle 46 extends inside the guide tube 47 up to the transmission unit 45 that meshes with the spindle 46 via a toothing.
  • FIG. 14 a variant of the corner profile shown in FIG. 10.3 can be seen.
  • the corner profile is configured as reinforcement profile 50 of metal that includes the edge of the slideout 6 and is screwed on the edge of the slideout 6 by means of screws 51 .
  • the screws 51 are covered with stoppers 56 .
  • the reinforcement profile 50 has an outer abutment 52 and a second inner abutment 54 .
  • the force transmission means 53 mounted to the slideout 6 fits to the abutment 52 .
  • the force transmission means 53 With an oblique flank or tilted angle, respectively, a positive locking of the slideout 6 with the superstructure 4 is obtained.
  • the seal 35 can be inflated with higher pressure than without said locking. Also, when the vehicle drives the suction wind cannot open the gap between the slideout 6 and the superstructure 4 . This all results in that the tightness is improved.
  • FIG. 16 it is apparent how the inner force transmission means 57 fits to the inner abutment 54 of the reinforcement profile 50 . This is the case whenever the slideout 6 is completely extended. Also here, forming ensures that the gap between the slideout 6 and the stationary part of the superstructure 4 cannot increase, e.g. when the seal 35 is inflated.
  • FIG. 17 a further variant of the reinforcement profile 50 is shown.
  • it additionally comprises an attachment option 55 .
  • This can be configured as a railing, for example. So, rollable awnings or the like can be attached to the roof of the superstructure 4 . Said even larger cross section provides for an even higher stiffening by the profile 50 .
  • FIG. 18 again a spatial view to the outer force transmission means 53 is apparent. It is a relative narrow claw-like part of metal in the embodiment shown.
