Definitions

  • the invention relates to a coupling arrangement as set. forth in the independent claim directed thereto, for cou- pling a trailer and a canopy mounted thereon, extending over the outer edges of the trailer side structures when viewed in a cross-section perpendicular to the longitudi- nal direction of the trailer, for raising the canopy to an open position raised from one end and lowering it to a closed position on the trailer on the top edge of its side structure-
  • the coupling arrangement reduces the effective interior space of the trailer.
  • the coupling arrange- ment is "among” the goods being transported in the trailer, which means that the goods can easily get into the artic- ulated arms of the hinge,units, preventing them from mov- ing, which may prevent the canopy from being opened, re- quiring special efforts to open it.
  • the locking arrangement for locking the canopy in its open position is conventionally implemented, for example, by means of a locking bar rotatably attached in connection with the base of the trailer, which also reserves space from the trailer.
  • a locking pin arrange- ment is also used, e.g., at the articulation point between the short articulation arm of the hinge unit,and the first frame member, where the problem is that, because of the high moment of force exerted on this articulation point when the canopy is open, the locked canopy, can still be lowered accidentally by excessive force without removing the locking pin, causing the locking pin arrangement to break the articulation.
  • Locking of the canopy in its closed position, on its part is conventionally executed by means of locking latches which are separately attached to it and lock the canopy to the top edge of the trailer side or to locking surfaces which are separately attached to the trailer's sides.
  • the disadvantage of the latter solution is that, when placed outside the sides of the trailer, the coupling arrangement is continuously exposed to dirt from underside of the trailer. For this reason, in particular due to contaminants such as, for example, road salt and freezing, the hinge units may require special methods to open the canopy, In addition, hinge units also require continuous maintenance and service for this reason.
  • the coupling arrange- ment of the invention is essentially characterized by what is set out in the characterizing part of the independent claim directed thereto.
  • the coupling arrangement of the invention is the simplicity and efficiency of its construction and assembly and its use, first of all be- cause it can be preassembled in place at the same time as the canopies are being manufactured, thus enabling effi- cient transportation of several canopies stacked on top of each other, ready to be mounted on the trailer,
  • a further advantage of the coupling arrangement is that it does not restrict the effective interior space of the trailer and, in addition, it is ’encapsulated" inside the trailer, constantly protected from environmental impuri- ties.
  • the oppositely grooved profiles of line frame members allow effective control of the rotation of the articulated arms so that the second frame member remains constantly in the same vertical plane as the first frame member,
  • a steering arrangement to maintain the second frame member in the same vertical plane as the first frame member when the canopy is being lowered to the closed position.
  • the hinge units of the coupling arrangement can be coupled to operate, for example, between the first frame member and the second articulated arm, thus allowing the hinge units, pre-assembied for installation in the canopies, to be stored and transported assembled with the gas spring located within the groove profile of the first frarae mernber.
  • Figure la is shown as a partial perspective view a preferred hinge unit of the coupling arrangement according to the invention in connection 'with the trailer side structure with the canopy closed
  • Figure lb is shown an embodiment of Figure la with the canopy- open
  • Figures 2a and 2b is shown the operation of a preferred locking ar- rangement.
  • FIGs 3a and 3b is shown a preferred locking arrangement for lock- • ing the canopy in its closed position, and a per- spective view of the embodiment shown in Figure 3a viewed from inside the trailer with the canopy closed, and in Figure 4 is shown as a perspective view of an embodiment of Figure la equipped with a mechanical lock viewed from the outside of the canopy.
  • the invention relates to a coupling arrangement for cou- pling a trailer P to a canopy K, placed on top of the trailer P and, when viewed in a cross-section perpendic- ular to the longitudinal direction s of the trailer, ex- tending over the outer edges U of the trailer side struc- ture L, for lifting the canopy, raised from one end to an open position II, and for lowering it to a closed position I on the trailer, on the top edge Y of its side structure
  • the coupling arrangement includes, for example, with reference to Figures la and lb, two hinge units X to be installed on the opposite sides of the trailer.
  • Each hinge unit consists of: a first elongated frame member 1 to be fixed on the trailer side structure L; a second elongated frame member 2 to be fixed in connection with the side wail of the canopy K; an articulation arrangement allowing the frame members 1, 2 to move in the substantially same vertical plane, consisting of articulation arms connected rotatably w in a substantially vertical plane to the frame members 1, 2, wherein the first articulation arm 3a con- nected to the first end of the frame members 1, 2 is substantially shorter than the second articulation arm 3b connected to the said frame members 1, 2; a lightening arrangement for facilitating the movement of the canopy, such as one or more mechanical 4a and/or auxiliary powered spring actuators 4b; and a locking arrangement for locking the canopy K in its open position II and closed position
  • the hinge units X of the coupling arrangement are mounted, for example with reference to Figure 3b, on the one hand above the top edges Y of the opposite side struc- tures L of the trailer, such as on top thereof, and on the other hand on the opposite side walls of the canopy K above the top edges Y of the side structures L of the trailer.
  • the walls of the canopy have projections for the hinge unit.
  • the first and second frame members 1, 2 of the hinge unit.X are arranged to face each other by means of open U--proflies, to the lateral flanges of which the articulation arms 3a, 3b connecting them are attached rotatably w.
  • the outer dimensions of the articula- tion arms 3a, 3b are most preferably rectangular in cross-section, and the free inner dimension of the U- profiles of the frame members i, 2 are arranged to provide a sliding fit between the same.
  • the lateral flanges of the U-profiles effectively control the movement w of the articulated arms 3a, 3b in the vertical plane defined by the first frame member 1,
  • the first and second frame members 1, 2 of the hinge unit X have substantially equal length, with the effect that the canopy in particular is significantly strengthened compared to current solutions where the second frame mem- ber is typically clearly shorter than the first frame member.
  • the bottom edge of the canopy K which is placed on the top edge Y of the trailer, is reinforced, with the exception of the location of the hinge unit X, by a stiffening structure J, such as a plastic, metal, composite profile or the like, which is further provided with a seal T underneath.
  • a stiffening structure J such as a plastic, metal, composite profile or the like
  • first frame member 1 acts as a seal against the top edge Y of the side, it is possible to provide a seal on its top surface against the wall of the canopy K when being closed. In this context, it is possible to further improve the sealing by using a second frame member 2 which is sub- stantially longer than the first frame member 1.
  • a further preferred embodiment is to equip the second frame member 2 with, for example, a flat exten- sion part, preferably about 70-100 mm long, in its rear- flange, which is arranged to be pushed, for example, with a tight fitting adjacent to the canopy stiffening structure J, making the hinge unit rigid in the transverse direction.
  • the first frame member 1 is connected to the canopy stiffening structure in a transversely guiding and yet longitudinally floating manner, thus allowing thermal expansion in different weather conditions.
  • the locking arrangement for locking the canopy K in its open position II comprises a locking arm 5a pivotally mounted on the second frame member 2 between the articulation points of the articulation arras
  • the locking movement of the locking arm 5a can be seif-directed, e.g., in a by utilizing gravity in a decelerating manner.
  • the locking and release move- ments of the locking arm may also be performed manually or by means of an auxiliary power-operated actuator.
  • the locking arrangement for locking the can- opy K in its closed position I preferably comprises a locking member 5b between the first and second frame mem- bers 1, 2, wherein further preferably with reference to
  • the locking member 5b is arranged with a locking hook pivotally coupled to the end of the second frame member 2, which locks to a locking pin at the end of the first frame member 1 in the closed position of the canopy K.
  • the locking arrangement 5 further preferably comprises a mechanical and/or electrical locking device 5c.
  • the lightening arrangement comprises, for example referring to Figures la, lb, 2a and 2b, one or more parallel gas springs 4b coupled to act between the first frame member 1 and the second articulated arm 3b. In this way, the lifting of heavier canopies can further be significantly facilitated.
  • the coupling arrangement further comprises a steering arrangement for keeping the second frame member 2 in the same vertical plane as the first frame member 1, in particular when the canopy K is lowered to a closed position.
  • the steering arrangement comprises, for example, a female steering mechanism 01 at the end of the first frame member 1 and a male steering mechanism 02 at the end of the second frame member 2, substantially transverse to it.
  • the coupling arrangement according to the invention fur- ther allows the hinge units X to be assembled in place on the canopy K during its manufacture, to enable the trans- portation of several canopies with hinge units preassem- bled for installation on trailers, stacked on top of each other.
  • the components of the coupling device of the invention may be made of a wide variety of materials, using a wide variety of manufacturing techniques, in ad- dition to the materials mentioned above, for example, any suitable plastic or composite material, or bio-based, re- cyclable or biodegradable synthetic or organic materials, such as for example cellulose, etc. It is also clear that the coupling arrangement can also be used for a canopy rotating about a transverse axis of rotation with respect to the longitudinal axis s, i,e., for the front and rear rails of the trailer instead of the side rails.
