DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

(9) The cargo bay construction represented in the drawings encompasses a floor 1, as well as the adjacent walls at the end of the floor 1, that limit the upwardly open cargo bay. It is seen in a longitudinal direction of the cargo bay construction, that an anterior front wall 2 is moved by being slid, while a back wall 3 is moved upwardly on hinges of the swivel joints 4, in order to provide unloading openings. Additionally, two fixed walls 5 are still designed.

(10) The front wall 2 is moved by being slid on the floor 1 along the longitudinal direction of the cargo bay construction, whereby the volume of the cargo bay can be changed. This can then be used to unload a stored load in the cargo bay from the opened back wall 3 over the unloading opening, which in comparison to tip troughs, can take place relatively constantly. The load can be sealed through the sliding of the front wall 2, which can be particularly designed for the closed back wall 3. FIGS. 1 to 3 show the front wall 2 in a position that it is as far away from the back wall 3 as possible. In this position, this limits the maximal cargo bay of the cargo bay construction

(11) In order to slide the front wall 2, a drive has been designed. This encompasses, for instance, a hydraulically functioning drive motor 6 arranged on the front end of the cargo bay construction, whose pinion shaft carries a drive pinion that cooperates with a chain section 8 of the drive mechanism 9. The gears of the drive pinion engage the chain, and consequently a positive locking connection is developed, through which the driving power from the drive motor 6 can be carried over to drive mechanism 9. The drive pinion simultaneously serves as a diverting gear for the drive mechanism 9.

(12) Drive mechanism 9 is open and is therefore not developed to be closed circumferentially. According to this, these two ends are exhibited that are respectively clamped to a drive slide 10 (compare FIG. 5). As a results of this, a first end developed from chain section 8 of drive mechanism 9 is connected with an end (referring to the longitudinal direction of the cargo bay construction) of drive slide 10 and the second end of the drive mechanism 9 is connected with the corresponding other end (referring to the longitudinal direction of the cargo bay construction) of drive slide 10. This second end of the drive mechanism 9 is developed by a cable section 11, that is sturdily connected with the chain section 8 to a connection point 12 and that is led over the arranged diverting roller 13 of the mechanism in the area of the back wall 3. In FIGS. 1 to 3 the indicated position of the front wall 2 is the connection point 12 and is positioned close to the diverting roller 13. Within the completely slid front wall 2 in the direction of the back wall 3, the connection point 12 is by contrast (additionally in the same run of the drive mechanism) positioned close to the diverting gear. Moreover, independent of the position of the slideable front wall 2, the chain section 8 is always led over the diverting gear and the cable section 11 over the diverting roller 13.

(13) Between the drive slide 10 and the end of the chain section 8 that is connected with the drive slide 10, a tension guide 14 is integrated. This encompasses a coil spring 15, that is preloaded between the drive slide 10 and a stop element 16 that is connected with the end of the chain section 8 and thereby holds the drive mechanism 9 preloaded in place.

(14) The drive mechanism is, with the exception of the section of drive mechanism 9 that is directly led over the diverting gear, arranged within a developed channel 17 from floor 1. This is also the case for the connection with the ends of section of the drive slide 10 serving drive mechanism 9. Channel 17 spans the cargo bay, which means that this is developed, referring to the main surface 18 of the floor, dropped upwards, whereby the integration of the drive mechanism is only locally limited by the height of the cargo bay, which means in the middle area of the (with reference to cross direction) longitudinal direction passing channel 17. Channel 17 also serves as the sideways guide of the sliding movement of the front wall 2, whereto channel 17 intervenes or is guided in a slot opening of front wall 2, and goes out from the edge of the front wall 2 from floor 1.

(15) The drive slide 10 is strongly connected with longitudinal beams 19 of a roll frame of the slideable front wall 2. For this, the mechanism serving vertical parts 20 of the drive slide 10 span the connection with the end of mechanism through a developed guide opening 21, spanning the longitudinal direction of the cargo bay construction in the upper side of channel 17. These vertical parts 20 are connected with face fit to channel 17 and overlaying cross sections 22 of the drive slide 10 are connected with the side members 19 of the roll frame (not represented in FIG. 7). A movement of the drive mechanism 9 by means of the drive motor 6 is consequently transferred to drive slide 10 on the front wall 2, whereby the front wall 2 is correspondingly shifted.

(16) In connection with the respective position of the front wall 2 a more or less long section of channel 17 is located within the cargo bay and the cargo stored in it is thereby exposed. In order to avoid the cargo intruding into guide opening 21, cover 23 has been implemented. For this, cover 23 is supported on the developed section of floor 1 by the upper side of channel 17. In this process, the integration of cover 23 into the upper side of channel 17 is succinctly executed in the fundamentals. This is thereby realized so that the channel 17 opening to the bottom is displaced and mounted down by two laterally limited longitudinal beams 24 to the channel inner space as well as by two on the longitudinal beams 24 (around the measure of the thickness of the cover 23), the channel inner space is developed with upward limited support 25 (compare FIG. 6).

(17) In the area of front wall 2, cover 23 is led above the drive slide 10, whereby this is lifted locally by channel 17 because of cross sections 22 connected with the longitudinal beams 18 of the roll frame laying on the upper side of channel 17. This however always takes place below the oriented front wall 2 which is obliquely tipped forward and is therefore outside of the cargo bay, so that no intrusions are to be expected into the developed gap by the cargo either laterally or through it from the side between the upper side of channel 17 and the under side of the cover 23.

(18) The local lifting of cover 23 through contact with the cross sections 22 of the drive slide 10 is achieved through a corresponding elastic deformability of cover 23. For this, this is developed from a sufficiently thin and thereby light elastic deformable steel sheet.

(19) In order to ensure that the lifting of cover 23 on the area below the roll frame of the front wall 2 remains limited, two rollers 26 which are arranged on the longitudinal axis ends of the roll frame are shifted, not only on the longitudinal beams 24 of channel 17 but rather also on the corresponding sections of cover 23, whereby the cover 23 is pushed from the rollers 26 on the upper side of channel 17.

(20) In order to prevent the cargo from intruding, especially in the sliding of the front wall 2, the developed gaps between the front wall 2 and the side walls 5 on the one hand, and front wall 2 and the floor 1 and on the other hand, are covered by strip like seal elements 27. Seal elements 27 are able to be turned, as depicted in FIG. 4 around an axis 28 that spans in the longitudinal direction of the respective gap that is to be sealed, fixed on the front wall 2 in a rotatable manner and with their sealing edges by means of a preloaded spring element 29, and fixed against the respective side wall 5 or the floor 1. This spring-loaded, turnable storage of the sealing element 27 serves not only to compensate for a shortening due to wear of the sealing element 27, but rather also to offset the changing width of the cargo bay. The side walls 5 pass namely continually from a parallel orientation in the area of the front end of the cargo bay construction in an increasing trapezoidal orientation in the back area, to the unloading opening developed end of the cargo bay construction, whereby the width between the upper edges of the side walls 5 in comparison to the width between the lower edges of the side wall 5 gets bigger. The expansion of the cargo bay in the direction of the back end ensures, through a replacement of the cargo from the sidewalls in sliding and thereby for a relatively low requirement for shift efficiency.

(21) FIG. 8 shows an alternative design for the sealing of the developed gap between the front wall 2 on the one hand and the side walls 5, as well as the floor 1 on the other. With this design, the strip-like seal elements 27 are developed to be fixed. An expansion of the cargo bay over the length of the cargo bay construction can compensate therefore for the difference in strength of the deformation of the seal elements 27.
