    LOADING DOOR LOCKING MECHANISM
    OBJECT OF THE INVENTION
    The invention relates to a locking mechanism for a door load basket according to the preamble of claim 1. In particular, the invention relates to a locking mechanism for the door of a vehicle used in road transport, such as a truck or a trailer.
    BACKGROUND OF THE INVENTION
    The truck or trailer load basket uses doors that can be turned, folded or moved to the side. When the load car has a folding door, the support rail of the folding doors is usually located near the upper edge of the door opening of the load car, and the support of the doors rests on the roof structure of the load car. In this case, the structure of the folding doors must be carefully designed so that the doors move well between the roof structure of the load body and the floor structure.
    The disadvantage of the known structure is often that when the support of the doors rests on the roof structure of the load car, the roof structure bends and the opened doors tend to press downwards. In this case, when the doors are closed, the interlocking locking members in the door and in the load body do not always coincide at the same height, which can make it difficult to close the doors. Therefore, especially in long body structures, the roof structure is often supported in the middle of the door opening by means of a support column, which prevents the roof structure from bending and facilitates the closing of the doors.
    Closing the doors of the truck is also complicated by the fact that the truck is a flexible structure that changes shape whenever the shape of the road surface under the truck or trailer changes. The resulting deformation of the load body can also cause the mating members of the locking members in the door and the load body not to fall exactly into place when the doors are closed. The unevenness of the ground surface at the place of loading or unloading can therefore also make it difficult to close the load compartment doors. To overcome this drawback, known door locking mechanisms often provide a sufficient amount of vertical clearance in the locking members to allow the door to be locked, even if the door locking members are not exactly in the correct position relative to the load body locking members 35.
    20180038 prh 13 -03- 2018
    However, the vertical clearance provided to facilitate the closing of the doors easily causes a problem of wear of the door locking members. This is due to the fact that, during transport, deformations take place in the load carriage due to the unevenness of the road, whereby the doors floating on the roof structure of the load carriage can move. In this case, the counterpieces of the locking members in the door and in the load body can also move relative to each other and can wear quickly. Worn locking members no longer lock the doors properly.
    OBJECT OF THE INVENTION
    The object of the invention is to provide a new door locking mechanism which does not have the above-mentioned drawbacks. It is a further object of the invention to provide a locking mechanism which operates reliably and is easier to use than known locking mechanisms.
    CHARACTERISTICS OF THE INVENTION
    The door locking mechanism according to the invention is characterized by what is set forth in the characterizing part of claim 1. The device according to the invention is also characterized by what is set out in the dependent claims.
    According to the invention, the lateral displacement of the doors is supported by the roof structure, but when the door is locked the weight of the door shifts to the locking member connected to the floor structure of the load body and the locking member supports the weight of the door. In order to carry out such an operation, the door locking mechanism according to the invention has a rolling surface which, when the door is closed, provides support and / or guidance so that the door rises to a height where the door locking members and the locking members of the load carriage are at a suitable height relative to each other. In this case, the door locking members and the locking members in connection with the floor structure of the load body can be easily locked together.
    The load compartment door is then easy to close and lock even in uneven terrain where the load compartment is not straight due to uneven terrain. In this case, due to the deformation of the load body, the locking parts of the door and the load body may not be on the same level. However, by means of the rolling surface according to the invention, the door can be raised to a suitable height when closed so that the locking members of the door and the locking members in connection with the floor structure of the load body can be easily locked to one another. The rolling surface supporting and / or guiding the door may be formed by one or more rollers, bearings, wheels, roller chains, balls or other similar rolling members, and the rolling member may be connected
    20180038 prh 13 -03- 2018 to the floor of the load body, to a locking device connected to the floor, to a door or to a locking device connected to the door. If the rolling surface has two or more rollers, then most preferably they are arranged so that together the rollers form an inclined rolling surface. In this case, the inclined rolling surface causes the door to rise upwards when the door moves over the rolling surface when the door is locked.
    According to the invention, when the door is closed, a rolling surface formed by at least one roller in the locking mechanism supports the door and lifts it upwards so that the locking members connected to the door and the load floor are at just the right height relative to each other. In this case, large clearances are not required in the locking members, but still it is easy to close and lock the door. In the structure according to the invention, when closing and locking the doors, the door locking members are easily locked even in the event that the roof structure is bent and the doors are depressed. Therefore, the structure according to the invention enables a lighter and simpler roof structure, and it is also possible to make the long body structures of the trailers 15 without supporting the roof structure in the middle of the door opening.
    When the rolling surface or roller in the door locking mechanism supports the door when the door is closed and locked, the door is easy to close and lock. Then it is also possible to make the structure 20 of the locking members so that the clearances are smaller. In this case, the locking members cannot move during driving, whereby the wear of the door flowering mechanisms according to the invention is considerably less than in known door structures.
    According to the invention, the closing of the door can take place in such a way that when the door is closed or the locking member connected to it 25 protrudes on a rolling surface connected to the floor of the load body.
    When the door is locked, the door can also be supported on this rolling surface. However, in the locking position, the door may be supported on a support surface in connection with the rolling surface. In this case, the weight of the door during driving does not strain the rolling surface used to close the door.
    However, in the locking mechanism according to the invention, the rolling surface can also be connected to the door. In this case, there is, for example, a counterpiece in connection with the floor of the load body, on which the rolling surface connected to the door rests. The counterpart then has, for example, a part formed by a sloping surface which carries the door during the closing movement. In addition, in connection with the door and the floor of the load basket 35, there may also be support surfaces which support the door when it is closed, so that the weight of the door does not stress the rolling surface during driving.
    20180038 prh 13 -03- 2018
    The locking mechanism of the load car door usually also has a vertical locking pin in connection with the floor and / or the roof of the load car, into which the hook-like locking cam of the locking member in the door locks. According to the invention, this pin can also be replaced by a locking roller. The rolling surface formed by the roller can also function in steering and locking the door.
    Correspondingly, the locking cam of the locking member can also be provided with a rolling surface, such as a roller, which locks on the locking pin. In this case, in either of the solutions according to the invention, the locking cam or its counterpart in the door does not wear in the same way as in the known locking members.
    Due to the above, the doors according to the invention close better and the door locking mechanisms also work better and more accurately. The locking mechanisms according to the invention also allow substantially smaller clearances than the known flowering mechanisms, because in the closing situation the doors according to the invention are well supported. In this case, deformations of the load body due to the unevenness of the chassis of the truck or trailer also do not make it difficult to close and lock the doors and substantially reduce the wear of the locking members.
    According to the above, the invention is a locking mechanism for a load car door, which includes a locking member at the bottom of the door and a locking member and a support member located in connection with the floor of the load car, which lock to each other when the door is closed. The locking mechanism comprises a rolling surface associated with a locking member at the bottom of the load compartment door or a locking and support member adjacent to the load floor which, when closed, causes the door to rise so that the door locking member and the load compartment floor locking member are at such a height that easily closed and locked, and the rolling surface may be formed by one or more rollers, bearings, wheels, roller chains, balls or similar rolling members.
    In the locking mechanism of the door, the rolling surface is placed in a locking and support member connected to the floor of the load body, and at the lower edge of the door there is a locking member coming on top of the rolling surface. Alternatively, in the door locking mechanism, the rolling surface is placed in a locking member at the bottom of the door, which, when the door is closed, rests on a locking and support member connected to the floor of the load body. In the door locking mechanism, the rolling surface formed by two or more rollers of the locking and support member connected to the floor of the load body and the support surface of the door are separate pieces or formed in one piece.
    In the door locking mechanism, the locking and support member most preferably also includes a vertical locking roller into which the locking tip of the locking member can be locked laterally. Further, the door locking mechanism includes a lock cam connected to the door and a locking and support member connected to the floor of the load body with a vertical locking roller into which the door lock cam can be locked.
    In the door locking mechanism, the folding door locking mechanism also includes one or more support surfaces connected to the floor of the load basket, on which the support plate connected to the door rests when the hopper is loaded.

    DESCRIPTION OF THE FIGURES
    Figure 1 is a schematic top view of the closing situation of the side doors of the load body. In Figure 1, the side door of the load body is a folding door 10 formed by three doors 20a, 20b and 20c connected to each other by hinges 21. When the folding door 10 is closed, in the first step the doors 20b and 20c move to the right in Fig. 1, whereby the locking member 33 on the right side of the door 20b belonging to the locking mechanism protrudes on the rolling surface locking and supporting member 43. Since the locking and support member 43 then supports the door, the doors 20a and 20b are now easy to press against the side of the load car floor 11, whereby the support plates 31 at the lower edges of the doors 20a and 20b also protrude over the load floor floor support surface 40 and the locking and support member 41. It can also be seen from Figure 1 that the locking cam 32 belonging to the door locking mechanism is in a position where it can be pushed into the locking and support member.
    41 and pivotable behind the locking roller 42 so that the locking cam 32 locks on the locking roller 42.
    20180038 prh 13 -03- 2018
    Since the folding door has two separate locking and support members in connection with the floor of the load body, the locking and support member 43 with a rolling surface can be said to be a first locking and support member and a locking and support member 41 with a locking roller 42 for a locking cam 32 can be said to be a second locking member. and as a support body.
    Fig. 2 shows a situation in which the locking member 33 belonging to the locking mechanism, on the right side of the door 20b, is on the locking and support member 43 connected to the floor of the load body. At the same time, the locking tip in the locking member 33 is pushed behind the locking roller 44 in the locking and support member 43, locking the right edge of the door 20b in place.
    In this case, the door 20a and the left edge of the door 20b connected to it by a hinge can be locked in place by turning the locking cam 32 of the locking member located in the door 20a behind the vertical locking roller 42 located in the locking and support member 41. If in some cases the locking roller 42 is not considered necessary, then it can also be replaced by a locking pin.
    The door 20c is then closed by pivoting it around the hinge 21, whereby the locking claw 34 belonging to the locking mechanism and connected to the door 20c rotates and locks behind the locking roller 44 in the locking and support member 43. When the door 20c is closed and turned against the edge of the load car floor 11, the door 20c is locked in place in the same way as the door 20a, i.e. the lock cam 32 of the door locking member, is turned behind the locking roller on the load car floor. Figure 3 shows a situation in which all the doors 20a, 20b and 20c of the folding door 10 of the load car are closed.
    Figures 4-6 show a schematic and illustrative view of the folding door 10 of the load car so that the locking members of the locking mechanism of the doors 20a, 20b and 20c are visible, although located under the doors, and not at least completely visible from above. In Fig. 4, the support plates 31 at the lower edges of the doors 20a, 20b and 20c protrude over the support surface 40 and the locking and support member 41 on the floor of the load body. The doors 20a and 20c are locked to the locking and support member 41 at the bottom of the load floor by turning the locking cam 32 of the locking member in the door behind the locking roller 42. The opposite edge of the door 20b is locked so that the locking tip 37 of the locking member 33 connected to the door protrudes behind the locking roller 44 located in the locking and support member 43 connected to the floor 11 of the load body.
    When the door 20c is closed by pivoting it around the hinge 21, the locking claw 34 connected to the door 20c rotates behind the locking roller 44 or pin in the locking and support member 43. The door 20c is then locked by turning the lock cam 32 of the locking member of the door 20c
    20180038 prh 13 -03- 2018 to the locking and support member 43 connected to the floor of the load body behind the locking roller 42 or pin.
    Figure 5 shows the locking members 41 and 43 in connection with the floor of the load body as seen from the side. Figure 6 shows a top view of the locking members 41 and 43 in connection with the floor of the load body.
    Figure 7 shows diagrammatically two three-part folding doors connected to the load body and opening in opposite directions. Figure 8 shows in more detail only the second folding door 10, since similar opening and closing operations also take place in the second folding door, but in opposite directions. In Figures 7 and 8, the doors are still so open that the structure of the locking and support member 43 included in the locking mechanism is shown in the figures. The locking and support member 43 has a rolling surface and a support surface 46 formed by rollers 45a and 45b.
    Fig. 9 shows a locking and support member 41 belonging to the load car floor 11 belonging to the locking mechanism, on which the support plate 31 at the lower edge of the door 20a moves or also rests. According to the invention, the support plate 31 connected to the door can be positioned so that when there is no load in the load car, there is a clearance between the support plate 31 and the locking and support member 41 in connection with the load car floor 11 when closing the door. Since, when the door 20 is closed, the support member 33 connected to the door already rests on the locking and support member 43 connected to the floor 11 of the load body, simultaneous support of the support plates 33 is not necessary. However, when loaded, the structures of the load body bend, whereby the support plate 31 connected to the door 20a can then be arranged to also rest on the locking and support member 41.
    In Fig. 10, the locking cam 32 of the locking member of the door 20a can be locked to a vertical locking roller 42 which can rotate, whereby wear between the locking parts is minimized. Fig. 10 shows a locking and support member 41 of the locking mechanism, in which, in addition to the vertical locking roller 42, there may also be a horizontal roller 45 which guides the locking cam 32 in the vertical locking situation.
    Fig. 11 shows an axonometric view of a locking and support member 43 belonging to a locking mechanism in connection with the floor 11 of the load car, with parts supporting the door or a locking member connected thereto, and in addition a locking part of the door. The door-supporting part is a rolling surface formed in Fig. 11 by two rollers 45a and 45b which support the door 35 or a locking member connected thereto when the door is closed. The height position or size of the rollers 45a and 45b may be arranged so that together they form an inclined rolling surface.
    The purpose of the rolling surface is to form a guide for the lower part of the door 20b
    20180038 prh 13 -03- 2018 to the locking member 33, shown in more detail in Figure 12. In the closed position, the door 20b could remain on the roller 45a or 45b of the locking and support member 43, but when locked the door 20b most preferably rests on the support surface 46 in the locking and support member 43, whereby the weight of the door does not remain on the rollers 45a or 45b.
    In Fig. 11, the rollers 45a and 45b of the locking and support member 43 of the locking mechanism and the support surface 46 are shown so that they are in the same piece. However, they can also be separate pieces so that the rollers 45a and 45b are in one piece and the support surface 46 or the plane in the other piece, although in practice these pieces work together when closing the door 10. In addition, the locking and support member 43 in connection with the floor 11 of the load car has a locking roller 44, behind which the locking tip 37 of the locking member 33 locks.
    Fig. 11B shows the structure of the locking and support member 43 in connection with the floor of the load body, in which the locking roller 44 is supported at its center by means of a support surface 46. In this case, the locking member 33 connected to the door 20b is locked to the part of the locking roller 44 above the support surface 46, and the locking claw 34 connected to the door 20c is locked to the part of the locking roller 44 below the support surface 46, respectively.
    Fig. 12 shows an axonometric view of a locking member 33 belonging to a locking mechanism 20 at the lower edge of the side door 20b of the load body, comprising a surface resting on the rollers 45a and 45b shown in Fig. 11 and a locking tip 37 projecting behind the locking roller 44 shown in Fig. 11. The locking member 33 of Fig. 12 is plate-shaped and has a slightly upwardly directed locking tip 37 which forms a sloping surface. When the door of the load body is closed, the locking tip 37 25 of the locking member 33 protrudes on the rollers 45a and 45b shown in Fig. 11 so that the door rests on the rollers 45a and 45b. Since the rollers 45a and 45b form an inclined rolling surface, at the same time they lift the door upwards. When the door is completely closed, the locking member 33 moves over the rollers 45a and 45b on a support surface 46 on which the locking member 33 and at the same time the door connected to it rest. The locking tip 37 of the locking member 33 locks behind the locking roller 44 shown in Fig. 11.
    Fig. 13 shows a locking member 33 of a locking mechanism for the lower edge of the side door 20b of the load body, the locking passage 37 of which has vertical load carrying rollers 36 or bearings and a horizontal load receiving roller 35. In this case, the locking and support member 43 of Fig. 11 need not have rollers 45a and 45b. be 35 only inclined plane surface.
    20180038 prh 13 -03- 2018
    Fig. 14 shows the locking member 33 of the locking mechanism at the lower edge of the side door 20b of the load car, the locking tip 37 of which has only a roller 35 receiving the horizontal load. Other solutions are possible. It is essential that at least one roller or bearing be placed where wear is possible.
    The locking members belonging to the locking mechanism at the bottom of the folding door have been described above. At least some of the corresponding members may also be located at the top of the door.
    Fig. 15 is an axonometric oblique side view of a detail of the folding door 10 opened. The figure shows the locking and support members 41 and 43 of the locking mechanism and their locking rollers 42 and 44, to which the locking members connected to the doors are locked.
    Fig. 16 shows the locking member 33 of the locking mechanism of the central door 20b of the folding door moving on the rollers 45a and 45b 15 of the rolling surface of the locking and support member 43 so that they begin to support the door 20b and the doors 20a and 20c hinged thereto.
    In Fig. 17, the locking member 33 of the locking mechanism of the central door 20b of the folding door has moved so far that it is already on the support surface 46 of the locking and support member 43. At the same time, the locking tip 37 in the locking member 33 is pushed behind the locking roller 44 in the locking and support member 43, locking the right edge of the door 20b in place. The door 20c is then pivotable, locking the locking claw 34 attached thereto behind the locking roller 44.
    Figures 18A-18C show a side view of the movement of the locking member 33 of the locking mechanism at the lower edge of the truck side door 20b to the locking and support member 43 adjacent to the truck floor. . In this case, the weight of the door 20b has caused the roof of the load car to bend and be depressed so that when the locking member 33 of the locking mechanism at the bottom of the door comes close to the locking and support member 43 connected to the floor of the car, the door 20b is also slightly depressed. As a result, in the locking mechanism, the locking member 33 at the bottom of the door 20b and the locking and support member 43 in connection with the floor of the load body are not at exactly the same height. In known solutions, it is precisely this situation that often causes major problems.
    20180038 prh 13 -03- 2018
    According to the invention, the locking members of the locking mechanism are made at the same height and at the same time easy to lock the door by arranging a rolling surface formed by rollers 45a and 45 in Figs. 18A-19C between the locking and supporting member 43 in connection with the load car floor.
    The purpose of the rolling surface is to raise the locking member 33 of the door 20b and at the same time the door in the locking situation so much that the door locking member 33 is at a suitable height with respect to the locking and support member 43 connected to the load car floor. In this case, in the locking mechanism, the locking and support members 33 and 43 of the door 20b and the load car which are connected to each other are easily locked to each other and the door 20b is easy to close.
    10
    According to the invention, the rolling surface used to lift the door 20b in the locking mechanism may be connected to either a locking and support member 43 in connection with the load car floor, as shown in Figure 11, or a locking member 33 at the bottom of the door 20b, as shown in Figure 13. and a rolling surface connected to the support member 43 is more preferable. Figures 18A-18C and Figures 19A-19C show a solution in which the rolling surface formed by the rollers 45a and 45 is located in a locking and support member 43 at the bottom of the side door 20b of the load body. When the door 20b is locked, the locking mechanism 33 at the bottom
    In Fig. 18A, the door 20b is closed and the locking member 33 of the locking mechanism located at the lower edge of the door 20b encounters the roller 45a of the locking surface of the locking and supporting member 43 of the locking mechanism connected to the floor of the load body. The end of the locking member 33 forms a locking tip 37 which is bent slightly upwards so that the locking member 33 25 rises well on the roller 45a.
    In Fig. 18B, the door 20b has moved further to the right in Fig. 18B so that the locking member 33 of the locking mechanism has already risen on the second roller 45b of the rolling surface. As the door 20b is further moved to the right in Fig. 18B, the locking member 33 moves over the support surface 46 30, as shown in Fig. 18C. The door 20b and its locking mechanism are now locked and the weight of the door 20b rests on the support surface 46. Such a locking situation of the locking mechanism is advantageous because during transport the weight of the door 20b does not stress the rollers 45a and 45b.
    It can be seen from Fig. 18C that while the locking member 33 of the locking mechanism moves to the right on the support surface 46 in Fig. 35 18C, the locking member 33 is also locked behind the locking roller 44. This locking event is also well seen in Figures 19A-19C, in which the movement of the locking member 33 at the bottom of the door 20b in contact with the floor of the load body
    20180038 prh 13 -03- 2018 with respect to the locking and support member 43 is seen from above. When the locking member 33 has risen on the rolling surface rollers 45a and 45b and further on the support surface 46, at the same time the locking tip 37 of the locking member 33 locks behind the vertical locking roller 44, whereby the door 20b and its locking mechanism are locked.
    Figure 20 is a side view of a side door of a load body formed by two three-part folding doors. The folding door parts 20a, 20b and 20c are connected to each other by hinges. The number of door sections may be greater than three, but most preferably the number of door sections is odd, such as three or five. The doors 20a and 20c have pivotable locking handles 47 connected to hook-like latches 32 by means of which the doors 20a and 20c can be locked to locking members 41 connected to the floor of the load body.
    Fig. 21 shows the closing function of the side doors 20a, 20 and 20c of the load body. When the doors 20a and 20b connected to each other 15 are hinged, they are pressed towards the locking member 41 in connection with the floor of the load body. It can be seen from Fig. 21 that the locking member 33 connected to the door 20b then protrudes on the rollers of the locking and support member 43 connected to the floor of the load body. In this case, the rollers of the locking and support member 43 lift the doors 20a and 20b upwards so that the locking members of the doors are at a suitable height with the locking members 20 connected to the floor of the load body and the doors are easy to lock.
    It can also be seen from Fig. 21 that when the doors 20a and 20b are pushed towards the locking member 41 in connection with the floor of the load body, the locking handle 47 is turned open. In this case, the hook-like locking cam 32 connected to the door 20a is in such a position that it can protrude into the locking member 41. When the doors 20a and 20b are pressed, the locking handle 47 is turned, whereby the hook-like locking cam 32 pivots behind the locking roller 42 and locks the door.
    The door 20c is then pivoted towards the second locking member 30 41 in connection with the floor of the load body. It can be seen from Figure 21 that the handle 46 of the door 20c is also in the open position, allowing the hook-like locking cam 32 of the door 20c to protrude into the locking member 41. The door 20c is locked by pivoting the handle 46, turning the hook-like locking cam 32 behind the locking roller 46
    The details of the locking mechanism of the load car door according to the invention are a locking member located at the lower edge of the door and a locking and support member located in connection with the floor of the truck, which lock to each other when the door is closed. In this case, the locking member at the bottom of the door or the locking and support member in connection with the floor of the load body has a rolling surface which, when closed, causes the door to rise so that the locking member and the locking member at the floor are at such a height that the door can be easily closed and lockable.
    In the locking mechanism, the rolling surface formed by one or more rollers is most preferably located in a locking and support member connected to the floor of the load body, and at the lower edge of the door there is a locking member on the rolling surface. The rolling surface formed by one or more rollers 10 may also be located in a locking member at the bottom of the door, which, when the door is closed, rests on a locking and support member connected to the floor of the load body.
    The rolling surface formed by the two or more rollers 15 of the locking and support member connected to the floor of the load body and the support surface of the door are separate pieces or are formed in one piece. In the locking mechanism, the locking and support member also includes a vertical roller into which the locking tip of the locking member can be locked laterally. The locking mechanism of the folding door may also include a locking and support member connected to the floor of the load body and having a vertical roller into which the locking cam 20 belonging to the locking member of the door can be locked. In the locking mechanism, the locking mechanism of the folding door also comprises one or more support surfaces connected to the floor of the load basket, on which the support plate connected to the door rests when the hopper is loaded.
