Description

The invention relates to a system for tensioning a side tarp on a commercial vehicle as well as a commercial vehicle body and a commercial vehicle with such a system.

Out DE 10 2006 044 207 B4 For example, there is known a system for tensioning a side curtain on a commercial vehicle body, the system comprising a winding shaft and a tensioning device. The tensioning device makes it possible to rotate the winding shaft, wherein the winding shaft can be positively connected to the tensioning device in order to transmit the rotational movement. For this purpose, the clamping device in particular a shaft journal, in which engages a coupling sleeve. The coupling sleeve is rotatably connected to the winding shaft. In other words, the coupling sleeve transmits the torque from the tensioning device to the winding shaft.

In order to make it possible to separate the winding shaft from the tensioning device, for example in order to be able to fully open the side tarpaulin of a commercial vehicle, a rotatable but tension-mounted handle is provided on the connecting sleeve. By means of the handle, the winding shaft can be lifted with the connecting sleeve and so separated from the shaft journal of the clamping device. The winding shaft can be removed laterally in this way. The rotatable mounting of the handle on the connecting sleeve is expedient, since in this way the winding shaft can continue to be rotated for tensioning the side tarp without the handle pinching in the narrow space between the winding shaft and a Eckrunge of the commercial vehicle.

A disadvantage of the known system, however, is the high design complexity. In particular, the tensile, but rotatable attachment of the handle requires a high production cost. In addition, the used, flexible handle is subject to high wear and should therefore be replaced regularly. This increases the maintenance of the prior art clamping system.

Against this background, it is an object of the invention to specify a system for tensioning a side tarpaulin on a commercial vehicle structure, in which the production of the winding shaft is simplified and the maintenance effort on the winding shaft is reduced. It is another object of the invention to provide a commercial vehicle body and a commercial vehicle with such a system.

According to the invention, this object is achieved by the subject matters of the independent claims 1, 9, 17 and 24, which relate in each case to a system for tensioning a side tarpaulin on a commercial vehicle body. With regard to the commercial vehicle body and a commercial vehicle with such a commercial vehicle body or a system described above, the above object is achieved by the subject matter of the independent claims 35 and 36.

The invention is based in particular on the idea of specifying a system for tensioning a side tarpaulin on a commercial vehicle body, which has a winding shaft which can be connected to an end portion of the side tarpaulin. Further, the system comprises a tensioning device for rotating the winding shaft, wherein the winding shaft is rotatably coupled or coupled to a shaft journal of the clamping device projecting over a housing of the clamping device. The invention is characterized in that between the winding shaft and the housing of the clamping device in a vertical guide on the commercial vehicle body slidably guided actuator is arranged, on which the winding shaft rests at least partially, so that the winding shaft by means of a vertical displacement of the actuating element of the shaft journal solvable, in particular, is liftable.

The invention thus provides for displacing the actuating element for removing the winding shaft from the winding shaft to the commercial vehicle body. At the commercial vehicle body, the actuating element is displaceably guided, thus allowing a guided movement of the winding shaft. As a result, the winding shaft can be lifted from the shaft journal and then removed laterally. Since the actuating element is guided displaceably on the commercial vehicle body, the actuating element remains on the commercial vehicle body and is thus held captive.

It is preferably provided that the vertical guide is formed in a corner post of the commercial vehicle body. In this case, the vertical guide can be arranged both on a rear side and on a front corner stanchion of the commercial vehicle body. The vertical guide is integrated in particular in the corner stanchion of the commercial vehicle body. In essence, the vertical guide can form a guide rail in which the actuating element can slide. For special equipment suitable vertical guides in the already existing corner stanchions are usually already provided, so that the invention can be easily retrofitted to existing vehicles. In general, the vertical guide can be used not only for the actuator, but also for other features of the commercial vehicle body.

The actuating element may, in preferred embodiments, at least in sections have an L-profile, wherein a vertical leg engages the L-profile in the vertical guide on the commercial vehicle body and a horizontal leg forms a support for the winding shaft. The design of the actuator as an L-profile is particularly easy to implement and thus cost possible.

The actuating element, in particular the horizontal leg, can further surround the shaft journal at least in sections. Preferably, the actuating element, in particular its horizontal leg, engage around the shaft journal such that when the winding shaft is inserted onto the shaft journal, the winding shaft comes to rest on the actuating element or the horizontal leg. The actuating element, in particular its horizontal leg, is thus preferably arranged between the winding shaft and the housing of the clamping device. In this way, it is ensured that by lifting the actuating element, a vertical force is applied to the winding shaft, so that there is a relative movement between the winding shaft and the tensioning device. Specifically, the winding shaft is removed from the clamping device or the housing of the clamping device, so that the shaft journal of the clamping device slides out of a corresponding receptacle in the winding shaft.

In this context, it should be noted that the winding shaft in the context of the present invention may also include a coupling sleeve which engages in the shaft journal. Specifically, the winding shaft having a clamping tube and a connecting sleeve, which are preferably positively and frictionally connected to each other, in particular pressed. The tensioning tube and the connecting sleeve together form the winding shaft. It can also be provided that the winding shaft is formed by a clamping tube and a connecting sleeve, wherein the coupling sleeve is positively, but rotatably or slidably connected to the clamping tube. Alternatively, the winding shaft may be formed exclusively by the clamping tube. In particular, it can be provided that the winding shaft is formed without a connecting sleeve.

It is generally pointed out that the tensioning tube of the winding shaft can be formed both by a tube with an inner through-channel. However, the present application likewise includes tensioning tubes which are formed from a solid material, in particular without material-saving internal cavities or passage channels.

In a further embodiment of the system according to the invention, it is provided that the actuating element, in particular the horizontal leg, has a gripping area which is freely accessible for manual gripping of the actuating element. In particular, the grip area of the commercial vehicle body, in particular the Eckrunge, so protrude that it is easily accessible. Concretely, the grip area can be dimensioned and arranged in such an area of the corner stanchion that is so far from installation that the grip area can be easily reached with one hand, in particular when using working gloves. This facilitates the operation of the system.

In a further embodiment of the invention can be provided that the actuating element, in particular the vertical leg, has a stop for limiting the vertical displacement of the actuating element. The stop can cooperate with a counter-stop on the commercial vehicle body, in particular the Eckrunge or the vertical guide, to limit the vertical displacement movement of the actuating element. This advantageously also causes a haptic feedback for the operator that the winding shaft is now sufficiently raised to be removed laterally.

In this respect, it is preferably provided that the actuating element in the vertical guide has a displacement which corresponds at least to the height of an effective portion of the shaft journal operatively connected to the winding shaft. The active portion of the shaft journal substantially corresponds to the part of the shaft journal, which engages fully inserted in the winding shaft in the winding shaft or a connecting sleeve of the winding shaft. The vertical guide offers, in particular up to the stop or counter-stop, a displacement height which corresponds at least to the height of this effective portion. This ensures that the actuating element can raise the winding shaft so far that the winding shaft is completely detachable from the shaft journal and thus removable.

The winding shaft preferably has a tensioning tube and a connecting sleeve. The connecting sleeve is preferably fixedly connected to the clamping tube, in particular pressed. At the same time the coupling sleeve is detachable, but rotatably coupled or coupled to the shaft journal. Concretely, the coupling sleeve can be positively connected to the shaft journal, so that a torque can be transmitted from the clamping device via the connecting sleeve to the clamping tube.

The invention is also based on the idea of specifying a system for tensioning a side tarp on a commercial vehicle body, the system having a winding shaft which is connectable to an end portion of the side tarpaulin. The system further comprises a tensioning device for rotating the winding shaft, wherein the winding shaft with a shaft journal of the clamping device rotatably coupled or coupled. The invention is characterized in that in the tensioning device, a vertically displaceably guided actuator is arranged so that the winding shaft by means of a vertical displacement of the actuating element of the shaft journal detachable, in particular liftable, is.

In this system, it is provided to integrate an actuating element in the clamping device. In this respect, the invention therefore provides for shifting the actuating element known from the prior art from the winding shaft into the tensioning device. As a result, the construction of the winding shaft is simplified, which saves manufacturing costs. The integration of the actuating element in the clamping device also has the advantage that the actuating element is arranged in a region of the commercial vehicle body, which is already designed to be easily accessible. The easy accessibility is in fact already provided for the operation of the clamping device itself. Since the operator expects operating elements in this area in any case, this also improves the user-friendliness of the entire commercial vehicle body.

In a preferred embodiment of the system is provided that the actuating element has a push rod which extends through a housing of the clamping device. Thus, the push rod is mounted in the housing of the clamping device and forms a total of the clamping device is a compact unit.

Specifically, it can be provided that the actuating element, in particular the push rod, extends through the shaft journal. This creates a possibility that the push rod acts directly on the winding shaft, which is placed on the shaft journal. This can be applied directly to the push rod lifting force on the winding shaft, whereby the winding shaft can be lifted off the shaft journal.

A particularly simple design of the clamping device with the actuating element is achieved in that the actuating element, in particular the push rod, is arranged coaxially to the shaft journal in the clamping device. Thus, it is achieved that the actuating element can be arranged independently of a rotational movement of the shaft journal in the clamping device. In other words, the shaft journal can rotate in this manner around the actuating element or the push rod. The push rod does not have to follow such a rotational movement.

The actuating element, in particular the push rod, preferably has a displacement path which corresponds at least to the height of an effective portion of the shaft journal operatively connected to the winding shaft. Specifically, the actuating element in the clamping device can be moved so far vertically that the winding shaft is lifted so far from the shaft journal by an upward movement of the actuating element or the push rod, that the winding shaft is completely separated from the shaft journal. The winding shaft can be easily removed in this way laterally or be separated from the tensioning device.

In order to facilitate the operation of the actuating element, it is preferably provided that the actuating element has an actuating plate which is fixedly connected to a lower end of the push rod. The actuator plate thus forms a support for a palm of an operator, so that manually the necessary pressure can be built to raise the winding shaft by means of the actuator.

The actuator may also include a stop which is fixedly connected to an upper end of the push rod and limits a downward movement of the actuating element. For this purpose, the stop preferably has a width which is greater than the width or the diameter of a passage for the push rod in the tensioning device. This prevents the actuating element from falling out of the clamping device.

Preferably, the winding shaft, in particular an engagement element of the winding shaft, on the push rod, in particular the stop, on. This is true in any case when the winding shaft is connected to the shaft journal. By the support of the winding shaft on the push rod is ensured that a surface contact between the push rod and the winding shaft is made, so that the winding shaft can be acted upon by an actuation of the actuating element with a vertical displacement force.

The invention is further based on the idea of specifying a system for tensioning a side tarpaulin on a commercial vehicle body, the system having a winding shaft connectable to an end portion of the side tarpaulin. The system also has a tensioning device for rotating the winding shaft, wherein the winding shaft can be non-rotatably coupled or coupled by means of a connecting sleeve with a shaft journal of the tensioning device. The invention is characterized in that the connecting sleeve is mounted displaceably along the winding shaft, so that the coupling between the winding shaft and the shaft journal can be released by a displacement of the connecting sleeve.

The invention thus causes a simplification and cost savings in the construction of the winding shaft, by dispensing with an additional handle, which is laboriously coupled with a connecting sleeve of the winding shaft. Instead, it is provided according to the invention to mount the connecting sleeve itself displaceable relative to the winding shaft, so that by merely lifting the connecting sleeve, the winding shaft of the shaft journal is separable. Additional elements that are subject to high wear, such as the known from the prior art flexible handle are avoided in this way. This also reduces the maintenance of the system according to the invention.

In a preferred embodiment of the invention it is provided that the connecting sleeve is rotatably connected to the winding shaft. This ensures that a torque which is provided by the tensioning device via the shaft journal can be transmitted by means of the connecting sleeve to a tensioning tube of the winding shaft. The tensioning tube and the connecting sleeve together form the winding shaft, which is releasable in total after displacement of the connecting sleeve of the shaft journal.

The connecting sleeve is preferably displaceable in a form-fitting manner along the winding shaft. In other words, a sliding joint is formed between the connecting sleeve and the winding shaft, in particular the tensioning tube, which permits a, in particular limited, relative movement between the connecting sleeve and the tensioning tube. However, the connection between the tensioning tube and the connecting sleeve is so durable that the connecting sleeve forms a unit with the tensioning device of the winding shaft.

The connecting sleeve can have an inner contour that corresponds to an outer contour of a clamping tube of the winding shaft and / or to an outer contour of the shaft journal. In other words, the coupling sleeve can be positively connected to both the clamping tube, and with the shaft journal. The outer contours of the tensioning tube and the shaft journal can be identical or at least partially identical. The connecting sleeve preferably has a uniform inner contour. This facilitates the production of the connecting sleeve. In particular, the connecting sleeve can be made as an extruded profile. The correspondences between the inner contour of the connecting sleeve and the outer contour of the tensioning tube or of the shaft journal preferably exist so far that a positive, rotationally fixed connection can be achieved between the connecting sleeve and the tensioning tube or the shaft journal.

In a particularly preferred embodiment of the system according to the invention, the connecting sleeve has at least one oblong hole opening, through which extends a laterally, in particular radially, projecting from the clamping tube guide pin. The guide pin cooperates with the slot opening such that a sliding joint between the coupling sleeve and the clamping tube is formed. In particular, the coupling sleeve in this manner is non-rotatable, but longitudinally slidably connected to the clamping tube. The torque of rotation is transmitted through the guide pin from the coupling sleeve on the clamping tube.

When the winding shaft is coupled to the tensioning device, it is preferably provided that the tensioning tube within the connecting sleeve stands upright on the shaft journal. This ensures that after lifting the connecting sleeve, the clamping tube is separable by a lateral displacement of the shaft journal. In particular, the coupling sleeve can be raised so far that there is no lateral guidance of the tensioning tube with respect to the shaft journal, so that the winding shaft can be removed from the shaft journal by a substantially horizontal displacement movement. This has the advantage that for the separation of the winding shaft of the tensioning device not the entire winding shaft including a tarpaulin attached thereto must be raised. Rather, it is also sufficient to lift the much lighter coupling sleeve and then subtract the winding shaft laterally from the shaft journal. This significantly facilitates the operation of the system according to the invention.

The invention is also based on the idea of specifying a system for tensioning a side tarp on a commercial vehicle body, the system having a winding shaft which is connectable to an end portion of the side tarpaulin. The system further comprises a tensioning device for rotating the winding shaft, wherein the tensioning device has a housing and a clamping lever rotatably mounted in the housing. The invention is characterized in that the winding shaft is fixed, but rotatably connected to the clamping lever, wherein the housing has a sliding bearing for the winding shaft, so that the winding shaft is displaceable from a coupling position to a release position, in which the winding shaft with the clamping lever is separable from the housing.

In the invention, therefore, in contrast to the prior art, the removal of the winding shaft is not achieved by a special construction of the winding shaft itself, but by a design of the clamping device. Due to the fixed connection of the winding shaft with the clamping lever, the clamping lever is also a double function Reason enough: On the one hand, the clamping lever serves in this way for rotating the winding shaft and thus for tensioning the side tarpaulin; On the other hand, the clamping lever serves as a handle for lifting the winding shaft, so that the winding shaft of the commercial vehicle body is separable. An additional handle element, as provided by the prior art, is avoided in this way.

In a preferred embodiment of the system according to the invention it is provided that the housing has a lower bearing leg and an upper bearing leg. In the lower bearing leg a slot for receiving the winding shaft and in the upper bearing leg, the sliding bearing is preferably formed. The formation of a slot in the lower bearing leg offers so far a comparatively large bearing surface for the clamping lever, so that a secure mounting of the clamping lever is ensured.

The slide bearing can be formed by a laterally open, in particular L-shaped, recess which is formed in the upper bearing leg. The recess may also have an undercut for supporting the winding shaft in the coupling position. Thus, the upper bearing leg provides good support for the winding shaft. Good support is expedient because the winding shaft can deform due to their length and acting on the winding shaft, high clamping loads when tensioning the tarpaulin. In order to be able to absorb these loads, which act essentially in a horizontal direction, in particular radially to the winding shaft, good storage in the upper bearing leg is expedient.

The laterally open recess may have a long hole congruent slot contour, with only a portion of a long side of the slot contour is open to the side. The laterally non-open section of the longitudinal side preferably forms the undercut of the recess.

In a preferred variant of the invention it can be provided that the housing has a blocking element which rotatably fixes the winding shaft in the coupling position. The blocking element may in particular be designed so that it interacts with the winding shaft, wherein a cooperation is possible only in the coupling position. Specifically, the blocking element can hold the winding shaft in the undercut of the sliding bearing. In other words, the blocking element can prevent the winding shaft from automatically moving from the coupling position into the release position, in particular sliding out of the undercut.

With regard to the blocking element is preferably provided that this has a recess which engages around the winding shaft in the coupling position. The recess is preferably arranged in the blocking element such that it engages around the winding shaft only in the coupling position. Thus, the recess prevents displacement of the winding shaft from the coupling position to the release position.

The blocking element may in particular be pivotally mounted on the upper bearing leg of the housing. Thus, the locking element is easily accessible and easy to use. To remove the winding shaft, the blocking element can be easily pivoted, so that the blocking element releases the winding shaft. The winding shaft can then be moved from the coupling position to the release position. To lock the winding shaft in the coupling position or in the undercut of the slide bearing the locking element is pivoted into the locked position. In this case, the recess in the blocking element engage around the winding shaft and thus fix the winding shaft in the coupling position. However, the fixation is sufficient only so far that a displacement movement of the winding shaft is prevented by the coupling position in the release position. In particular, the rotational capability of the winding shaft is retained.

In a preferred embodiment of the invention, the winding shaft has a longitudinal axial projection which extends into the tensioning device. The longitudinal axial extension can be dimensioned so that it engages in the slide bearing. In particular, the longitudinal axial extension may have a cross-sectional diameter which is smaller than the cross-sectional diameter of a tension tube of the winding shaft. The winding shaft preferably comprises the longitudinal axial extension and the tensioning tube, wherein tensioning tube and extension can be integrally connected to each other. By the longitudinal axial extension having a smaller diameter than the clamping tube, it is possible that the clamping tube rests on the housing of the clamping device. So the winding shaft can be stored vertically.

It is preferably provided that the slide bearing and / or the recess in the locking element are adapted to the dimensions of the extension of the winding shaft. The extension extends in particular in the slide bearing. In addition, the locking element can embrace the extension in the coupling position of the winding shaft and hold in the coupling position.

In a further preferred embodiment of the invention it is provided that the winding shaft, in particular the extension, is rotatably connected to a gear which is rotatably mounted in the clamping lever. The gear allows the tensioning of the winding shaft by means of the tensioning device. The gear is preferably fixed, in particular rotatably connected to the winding shaft. By the extension is firmly connected to the gear, a vertical mounting of the winding shaft is achieved in this way.

The tensioning device, in preferred variants, has a latching element which cooperates with the toothed wheel as a ratchet mechanism for tensioning the side tarpaulin. The combination of the gear with the locking element makes it possible to tension by means of the clamping lever, the winding shaft successively with the same direction of rotation. So can be applied to the winding shaft with the clamping lever high forces for tensioning the side tarpaulin. This ensures that sufficiently high forces are transmitted to the side tarpaulin of a commercial vehicle body in order to clamp the side wall of the commercial vehicle firmly and safely.

The latching element preferably forms part of the clamping device. In this respect, the latching element is preferably fixed in the housing of the clamping device. The tensioning device forms a compact unit so far, which is uniformly mounted on a commercial vehicle body.

The invention also relates to a commercial vehicle body having a system as described above. The utility vehicle structure may also include one or more of the above systems. The systems of a commercial vehicle body may be similar or different. In particular, the systems described above can be combined with each other arbitrarily on a commercial vehicle body. The commercial vehicle body may further include at least one side curtain connectable or connected to a winding shaft of the side curtain tensioning system. The commercial vehicle body preferably includes a height adjustable roof. In that regard, it is preferably provided that a side tarpaulin, which is connected to the winding shaft, is displaceable along the winding shaft relative to the winding shaft.

Furthermore, the invention relates to a commercial vehicle, in particular a tarp semitrailer, with a system or commercial vehicle structure described above.

In 1 For example, there is shown a system for tensioning a side curtain on a commercial vehicle body, the system comprising a winding shaft 10 and a tensioning device 20 having. Further, an actuator 40 provided that the release of the winding shaft 10 from the tensioning device 20 allows.

The winding shaft 10 has a connecting sleeve 11 and a tension tube 12 on. The tension tube 12 is with the connecting sleeve 11 press-fitted. The tension tube 12 includes a Kederaufnahme 13 with which an end section of a tarpaulin, in particular a piping integrated in a side tarpaulin, of the commercial vehicle body can be connected. The Kederaufnahme 13 can extend over the entire length of the tension tube 12 extend. In the sectional view according to 1 it can be seen that the tension tube 12 further comprises a moon-shaped or sickle-shaped inner channel. This inner channel is used in particular to save material, which production costs can be reduced.

The connecting sleeve 11 has an inner contour, at least for Kederaufnahme 13 may be formed correspondingly. Specifically, it is provided that the coupling sleeve 11 has an inner contour, at least partially in the Kederaufnahme 13 intervenes. In this way, a torsion-proof connection between the clamping tube 12 and the connecting sleeve 11 guaranteed. In particular, in this way a torque from the coupling sleeve 11 on the tension tube 12 be transmitted.

The tensioning device 20 includes a housing 23 that is substantially U-shaped. Specifically, the housing faces 23 a lower bearing leg 23a , an upper bearing leg 23b and a connecting bridge 23c on. The upper bearing leg 23b and the lower bearing leg 23a are aligned substantially parallel to each other. The connecting bridge 23c connects the bearing legs 23a . 23b , Furthermore, the connecting web is used 23c to do this, the tensioner 20 or the housing 23 with a commercial vehicle body, in particular a corner stanchion 30 of commercial vehicle construction, to connect.

Inside the case 23 is a tension lever 22 pivoted. The tension lever 22 engages a gear wheel 22a that with a shaft journal 21 rotatably connected. The shaft journal 21 stands over the housing 23 , in particular the upper bearing leg 23b , in front and engages in the connecting sleeve 11 the winding shaft 10 one.

The shaft journal 21 preferably has an outer contour, which leads to an inner contour of the connecting sleeve 11 corresponds. Specifically, it can be provided that the shaft journal 21 has a rectangular, in particular square, outer contour. The connecting sleeve 11 also has a rectangular or square inner contour at least in a lower section. In this way it is ensured that the shaft journal 21 positively in the coupling sleeve 11 engages, in particular so that a torque from the shaft journal 21 on the coupling sleeve 11 can be transferred.

Inside the case 23 is also a locking element 22b arranged with the gear 22a interacts. The locking element 22b forms with the gear 22a a ratchet mechanism. Here is the cocking lever 22 preferably so with the gear 22a coupled to that gear 22a during a pivoting movement of the clamping lever 22 taken in a first pivoting direction and a pivoting movement of the clamping lever 22 is not taken in a second, opposite pivoting movement. The tension lever 22 So it makes the gear possible 22a to rotate, this rotational movement over the shaft journal 21 and the connecting sleeve 11 to the tension tube 12 the winding shaft 10 is transmitted. This can be a side tarp of a commercial vehicle body tension.

Between the upper bearing leg 23b the tensioning device 20 and the connecting sleeve 11 the winding shaft 10 is an actuator 40 arranged. The actuator 40 forms an L-profile. In particular, the actuating element 40 be designed as a sheet metal part with an L-profile. The L-profile has a vertical leg 41 and a horizontal leg 42 on. The vertical leg 41 is in a vertical guide 31 led to the commercial vehicle body. The vertical guide 31 is specifically formed in a Eckrunge 30 of the commercial vehicle body.

The vertical guide 31 is formed in particular by a rail-like receptacle, in which the vertical leg 41 of the actuating element 40 is vertically movable. The vertical guide 31 is already available for additional attachments in many commercial vehicle bodies and can also be advantageous for guiding the actuator 40 be used in the system according to the invention for tensioning a side tarpaulin. In this respect, the system according to the invention can be easily retrofitted.

The horizontal thigh 42 extends substantially parallel to the upper bearing leg 23b of the housing 23 the tensioning device 20 , The horizontal thigh 42 includes an opening that the shaft journal 21 encloses. In other words, the shaft journal extends 21 through an opening in the horizontal leg 42 of the actuating element 40 , In a coupling position between the winding shaft 10 and the tensioning device 20 is the winding shaft 10 on the horizontal thigh 42 of the actuating element 40 on.

The horizontal thigh 42 also carries a grip area 43 that is integral with the actuator 40 can be trained. Out 1 it can be seen that the grip area 43 is formed by sheet metal deformation of the sheet metal part, which forms the actuating element. The grip area allows the easy gripping of the actuator 40 so that this is easy to use.

To a vertical displacement movement of the actuating element 40 in the vertical guide 31 to limit, it is provided that the actuator 40 also a stop 44 having. The stop 44 is in the embodiment according to 1 through the horizontal leg 42 of the actuating element 40 self-educated. The horizontal thigh 42 is dimensioned so that when lifting the actuator 40 against a counter-attack 32 at the corner stanchion 30 strikes. In this way, a vertical displacement movement of the actuating element 40 limited.

The actuator 40 allows the winding shaft 10 from the tensioning device 20 to separate. This is desirable in order to fully open a side tarpaulin of a commercial vehicle. 1 essentially shows the coupling position between the winding shaft 10 and the tensioning device 20 , For the sake of clarity, however, the winding shaft 10 not completely on the actuator, in particular its horizontal leg 42 , shown lying on top. Rather, a drawing is purely a distance between the winding shaft and the connecting sleeve 11 and the horizontal leg 42 of the actuating element 40 shown. Actually, the winding shaft is located 10 completely in the coupling position on the horizontal leg 42 of the actuating element 40 on.

For removing the winding shaft 10 becomes the actuator 40 lifted vertically upwards. This can be the grip area 43 gripped and the actuator 40 in the vertical guide 31 pushed upwards. The sliding movement is caused by the stop 44 and the counter-attack 32 limited. Once the actuator 40 the counter-attack 32 has reached is the winding shaft 10 so far from the shaft journal 21 lifted that off the shaft journal 21 no longer in the coupling sleeve 11 intervenes. Rather, the winding shaft 10 free and can be removed from the side. In this respect, it is preferably provided that the shaft journal 21 engages over a length in the connecting sleeve 11, which is smaller than the displacement of the actuating element 40 ,

In the 2 and 3 an embodiment of a system for tensioning a side tarpaulin of a commercial vehicle is shown. The system comprises a tensioning device 20 and a winding shaft 10 , wherein the winding shaft 10 in the 2 and 3 not shown. Further, an actuator 40 provided, the vertically displaceable in the clamping device 20 is arranged.

The tensioning device 20 is essentially analogous to the clamping device 20 according to 1 educated. The tensioning device 20 includes a housing 23 that is substantially U-shaped. Specifically, the housing faces 23 a lower bearing leg 23a , an upper bearing leg 23b and a connecting bridge 23c on. The upper bearing leg 23b and the lower bearing leg 23a are aligned substantially parallel to each other. The connecting bridge 23c connects the bearing legs 23a . 23b , Furthermore, the connecting web is used 23c to do this, the tensioner 20 or the housing 23 with a commercial vehicle body, in particular a corner stanchion 30 of commercial vehicle construction, to connect. The tension lever 22 extends between the bearing legs 23a and 23b and is in the case 23 pivoted.

In the 2 and 3 is also a release lever 22c shown mechanically with a locking element 22b connected is. The locking element 22b engages in a gear 22a one. With the release lever 22c the latching element 22 can be brought into a position in which the latching element 22b not in the gear 22a intervenes. In this way, the gear can 22a be released.

The gear 22a is non-rotatable with a shaft journal 21 connected. The shaft journal 21 stands over the housing 23 in front. The shaft journal 21 is designed to be in a winding shaft 10 can intervene. Preferably, the shaft journal engages 21 in the winding shaft 10 a positive fit, so that the shaft journal 21 a torque to the winding shaft 10 can be transferred. Specifically, it can be provided that the winding shaft 10 an engagement element which, in a recess in the shaft journal 21 intervenes. The engagement element in the winding shaft can in an interior of the winding shaft 10 be educated. As in 2 well recognizable, the shaft journal points 21 a slot-shaped receptacle for an engagement element of the winding shaft 10 on. The slot-shaped receptacle extends radially completely through the shaft journal 21.

Coaxial to the shaft journal 21 or along a rotation axis of the shaft journal 21 is an actuator 40 in the form of a push rod 45 arranged. The push rod 45 extends through the housing 23 the tensioning device 20 , In particular, the push rod extends 45 coaxially through the shaft journal 21. The push rod 45 has a length that is at least the height of the housing 23 plus the height of the shaft journal 21 equivalent.

At a lower end of the push rod 45 is an actuator plate 46 attached. The actuator plate 46 Forms a support surface for the hand of an operator, so that an operator pushrod 45 can move slightly vertically. The sliding movement of the push rod 45 is in the 2 and 3 indicated by corresponding arrows.

At an upper end of the push rod 45 has the actuating element 40 a stop 44 on. The stop 44 is designed so that falling out of the push rod 45 from the shaft journal 21 is prevented. For this purpose, the stop 44 preferably has a width which is greater than the diameter of a passage opening through which the push rod 45 is guided.

In 2 is the coupling position of the actuating element 40 shown. The push rod 45 is shifted down so that the stop 44 on a bottom of the shaft journal 21 rests. It is preferably provided that the push rod 45 automatically gets into the coupling position. In particular, the weight of the actuator extends 40 off to the actuator 40 automatically transfer to the coupling position.

In the coupling position is the winding shaft 10 rotatably with the shaft journal 21 connected. To release the winding shaft 10 becomes the actuator 40 moved vertically upwards. The push rod 45 moves up to an upper edge of the shaft journal 21 , The engagement element of the winding shaft 10 that on the stop 44 the push rod 45 rests, transmits the vertical motive power of the push rod 45 on the winding shaft 10 , In this way, the winding shaft 10 raised. This is the winding shaft 10 raised so far that the shaft journal completely out of a corresponding receiving area of the winding shaft 10 moved out. The winding shaft 10 is thus released and can be removed from the side.

Once the over the actuator plate 46 on the push rod 45 manually applied force to release the winding shaft 10 omitted, an operator so the actuator plate 46 lets go, causes the weight of the actuator 40 that this back to the starting position, in particular the coupling position, falls back ( 2 ).

In the 4 to 6 another embodiment of a system for tensioning a side tarp on a commercial vehicle body is shown. The system comprises a winding shaft 10 and a tensioning device 20 , The tensioning device 20 is similar in construction to the tensioning device 20 according to 2 and 3 ,

The tensioning device 20 includes a housing 23 that is substantially U-shaped. Specifically, the housing faces 23 a lower bearing leg 23a , an upper bearing leg 23b and a connecting bridge 23c on. The upper bearing leg 23b and the lower bearing leg 23a are aligned substantially parallel to each other. The connecting bridge 23c connects the bearing legs 23a . 23b , Furthermore, the connecting web is used 23c to do this, the tensioner 20 or the housing 23 with a commercial vehicle body, in particular a corner stanchion 30 of commercial vehicle construction, to connect. The tension lever 22 extends between the bearing legs 23a and 23b and is in the case 23 pivoted.

The tensioner also has a release lever 22c on, the mechanical with a locking element 22b connected is. The locking element 22b engages in a gear 22a one. With the release lever 22c the latching element 22 can be brought into a position in which the latching element 22b not in the gear 22a intervenes. In this way, the gear can 22a be released.

The gear 22a is non-rotatable with a shaft journal 21 connected. The shaft journal 21 stands over the housing 23 in front. The shaft journal 21 is designed to be in a winding shaft 10 can intervene. Preferably, the shaft journal engages 21 in the winding shaft 10 a positive fit, so that the shaft journal 21 a torque to the winding shaft 10 can be transferred.

The winding shaft 10 includes a tension tube 12 and a coupling sleeve 11 , The connecting sleeve 11 is along the tension tube 12 slidably mounted. Specifically, it is provided that the coupling sleeve 11 at least one slot opening 15 having, wherein the length of the slot opening 15 at least the height of one with the coupling sleeve 11 effectively connected operative portion of the shaft journal 21 the tensioning device 20 equivalent. In other words, the coupling sleeve can be raised so far that the shaft journal 21 is completely exposed.

The slot opening 15 interacts with a guide pin 24 in the clamping tube 12 is fixed. The guide pin 14 extends substantially radially beyond the outer circumference of the tension tube 12 out and reaches into the slot opening 15 the connecting sleeve 11 one. The connecting sleeve 11 may additionally have an inner contour which is at least partially complementary to the Kederaufnahme 13 of the tension tube 12 is, so that a rotationally fixed connection of the coupling sleeve 11 also via an engagement of an inner contour of the connecting sleeve 11 in the Kederaufnahme 13 is ensured. The connecting sleeve 11 has a uniform inner contour over its entire length. Consequently, the shaft journal also points 21 an outer contour, the inner contour of the coupling sleeve 11 complementary is. In particular, the shaft journal 21 have an outer contour, one of the Kederaufnahme 13 having corresponding recess.

The connecting sleeve 11 is over the slot opening 15 and the guide pin 14 rotatably, but slidably, on the clamping tube 12 fixed. The dead weight of the coupling sleeve 11 preferably ensures that the connecting sleeve 11 automatically enters or falls in a coupling position. An automatically assumed coupling position of the connecting sleeve 11 is in 5 shown by way of example. The coupling sleeve engages around 11 a lower section of the tension tube 12 as well as the shaft journal 21 , The connecting sleeve 11 is in this case preferably form-fitting with the shaft journal 21 insofar coupled as a torque from the shaft journal 21 on the coupling sleeve 11 is transferable. This is for example by an outer contour of the shaft journal 21 allows, to an inner contour of the coupling sleeve 11 is complementary.

The tension tube 12 the winding shaft 10 is preferably blunt on the shaft journal 21 on. This is in 6 good to see. By lifting the connecting sleeve 11 can the coupling sleeve 11 thus be transferred from the coupling position to a release position. In the release position is the coupling sleeve 11 raised so far that they are the shaft journal 21 no longer embraces. Rather, the coupling sleeve 11 so completely from the connecting pin 21 solved.

This is in the 4 and 6 shown, wherein the side view according to 4 good to see that the shaft journal 21 in the release position of the connecting sleeve 11 is completely exposed. In the release position, the winding shaft 10 just to the side of the shaft journal 21 subtracted from. The winding shaft 10 so can from the jig 20 be solved.

7 shows a further embodiment of a system for tensioning a side tarpaulin of a commercial vehicle body, which the operating principle of the embodiment according to 4 to 6 picks up. Specifically, a coupling sleeve 11 provided along the tension tube 12 the winding shaft 10 is displaceable. The sliding movement is by a stop, analogous to the guide pin 14 , limited. The connecting sleeve 11 is so displaceable that the shaft journal 21 the tensioning device 20 is completely exposed in a release position, so that the winding shaft 10 can be removed laterally.

The non-rotatable yet movable connection between the coupling sleeve 11 and the tension tube 12 is in the embodiment according to 7 However, solved that, the winding shaft 10 has a rectangular outer contour. Instead of a substantially round winding shaft 10 as in the embodiment according to 4 to 6 So it's a square winding shaft 10 intended. Likewise, the coupling sleeve 11 angularly formed. In particular, at least the inner contour of the connecting sleeve 11 is rectangular. The inner contour of the coupling sleeve 11 Corresponds to the extent to the outer contour of the winding shaft 10 ,

The stop for limiting the displacement movement is according to the embodiment 7 not formed by a guide pin in a slot opening of the coupling sleeve 11 intervenes. Rather, a stop by a screw or generally a stop element 17 formed in a coupling position spaced from the coupling sleeve 11 in the winding shaft 10 is fixed. The stop element 17 stands over the outer contour of the clamping tube 12 before and thus limits the height movement of the connecting sleeve 11 , To a non-rotatable coupling of the coupling sleeve 11 with the shaft journal 21 In the coupling position, it is also provided that the shaft journal 21 also has a rectangular outer contour. The outer contour of the shaft journal 21 Corresponds to the extent to the inner contour of the coupling sleeve 11 ,

In the 8th to 10 two embodiments of a system for tensioning a side tarpaulin on a commercial vehicle structure are shown, in which the operating principle is based on the idea, the clamping lever 22 the tensioning device 20 as an actuator 40 to remove the winding shaft 10 use.

Specifically, the system has a winding shaft for this purpose 10 on, with the clamping lever 22 fixed, but rotatable, is connected. In particular, the winding shaft 10 with a gear 22a of the clamping lever 22 be firmly connected, with the clamping lever 22 opposite the gear 22a is rotatable. Specifically, it can be provided that the tensioning lever 22 with the gear 22a so cooperates, that during a pivoting movement of the clamping lever 22 in a first pivoting direction, the gear is taken. In a pivoting movement of the clamping lever 22 in a second, opposite pivoting direction is the clamping lever 22 opposite the gear 22a but relatively rotatable. In other words, the tension lever 22 with the gear 22a preferably connected so that by swinging back and forth of the clamping lever 22, the gear 22a is rotated sequentially only in a single direction.

The winding shaft 10 has in the embodiments according to 8th to 10 a tension tube 12 on, preferably a Kederaufnahme 13 includes. The Kederaufnahme 13 can extend over the entire length of the tension tube 12 extend. Furthermore, the winding shaft 10 a longitudinal axial extension 16 on, stuck with the tension tube 12 connected, in particular integrally with the clamping tube 12 is trained. The extension 16 extends into the gear 22a and is with the gear 22a preferably rotatably connected. The extension 16 has a cross-sectional diameter which is smaller than the cross-sectional diameter of the tension tube 12 is. A coupling sleeve 11 is in accordance with the embodiments 8th to 10 not required or provided.

The tensioning device 20 has in the embodiments according to 8th to 10 a housing 23 on. The housing 23 includes a lower bearing leg 23a and an upper bearing leg 23b , The upper bearing leg 23b and the lower bearing leg 23a are preferably aligned parallel to each other. Between the bearing legs 23a . 23b extends a connecting bridge 23c which preferably is integral with the bearing legs 23a . 23b is trained. The housing 23 is formed overall as a U-profile.

In the lower bearing leg 23a is a receiving opening 23c formed, the longitudinal axial extension 16 the winding shaft 10 receives. The upper bearing leg 23b comprises an L-shaped recess 26. The L-shaped recess 26 is preferably dimensioned so that the winding shaft 10 with the clamping lever 22 can be lifted vertically upwards out of the receiving opening 24c when the clamping lever 22 essentially at right angles to the connecting web 23c is aligned.

In 8th For example, it can be seen that with a right-angled orientation of the clamping lever 22 opposite the connecting bridge 23c of the housing 23 a release position for the winding shaft 10 is present. The tension lever 22 can as an actuator 40 be gripped and raised, with the fixed connection to the winding shaft 10 the winding shaft 10 is released from the receiving opening 24c. The winding shaft 10 so can from the case 23 the tensioning device 20 be separated.

When the longitudinal axial extension 16 the winding shaft 10 arranged in the receiving opening 24c and the clamping lever 22 essentially parallel to the connector 23c pivoted, limited the upper bearing leg 23b a vertical movement of the winding shaft 10 or the clamping lever 22 , This is the winding shaft 10 in a coupling position with respect to the housing 23 ,

In the 9 and 10 is a special design of a housing 23 the tensioning device 20 shown, being in the housing 23 a slide bearing 24 is provided. The slide bearing 24 comprises a receiving opening 24c in the lower bearing leg 23a , The receiving opening 24c is formed as a slot 25. The slot 25 extends with its longitudinal axis parallel to the connecting web 23c ,

In the upper bearing leg 23b an L-shaped recess 26 is arranged. The L-shaped recess 26 essentially has a slot contour which corresponds to the contour of the slot 25. Specifically, the L-shaped recess 26 is formed by a slot contour, which is substantially congruent to the slot 25 in the lower bearing leg 23a is trained. At the same time, the recess 26 in the upper bearing leg 23b laterally open in sections, so that overall results in an L-shaped recess 26.

In contrast to the embodiment according to 8th The release position is not by pivoting the clamping lever 22 in a right angle to the connecting bridge 23c arranged situation reached. Rather, based on the slot 25 and the recess 26 with a laterally open slot contour a transfer of the winding shaft 10 from a coupling position to a release position by longitudinal displacement of the clamping lever 22 along the connecting bridge 23c be achieved.

In 9 the coupling position is shown. It can be seen that the tension lever 22 with the gear 22a arranged so that the gear 22a with a locking element 22b interacts in the housing 23 is fixed. The winding shaft 10 is by means of a longitudinal axial extension 16 rotatably with the gear 22a connected. The longitudinal axial extension 16 is guided in the coupling position in an undercut which in the L-shaped recess 26 of the upper bearing leg 23b is trained. The undercut fixes the extension 16 in at least three directions.

By longitudinal displacement of the clamping lever 22 along the connecting bridge 23c can the extension 16 on the tension tube 12 be moved along the recess 26 until the extension 16 in the region of the lateral opening of the recess 26 in the upper bearing leg 23b is arranged. In this way, now the winding shaft 10 with the clamping lever 22 be removed laterally. The longitudinal axial extension 16 is thus removed from the slide bearing 24 side.

To prevent the winding shaft 10 automatically shifts into the release position, a blocking element 27 is provided. The blocking element 27 may be formed as a contoured sheet metal part. The blocking element 27 is pivotable on the upper bearing leg 23b of the housing 23 attached. In the blocking element 27 is a recess 28th provided, which has a width which is at least the diameter of the longitudinal axial extension 16 the winding shaft corresponds. Preferably, the width of the recess 28 is not more than the diameter of the clamping tube 12 ,

The recess 28 is positioned in the locking element 27 so that the recess 28 the longitudinal axial extension 16 the winding shaft 10 engages when the longitudinal axial extension 16 in the undercut of the recess 26 in the upper bearing leg 23b is positioned. In other words, the recess 28 engages around the longitudinal axial extension 16 in the coupling position of the winding shaft 10 , To transfer the winding shaft 10 Consequently, in the release position, first the locking element 27 is to be pivoted so that the recess 28 is the longitudinal axial extension 16 releases. Then the tension lever can 22 as an actuator 40 gripped and parallel to the connecting bridge 23c be moved. This will get the extension 16 in the region of the lateral opening of the L-shaped recess 26 in the upper bearing leg 23b , The winding shaft 10 so can work together with the clamping lever 22 be removed laterally. In this way, the winding shaft 10 with the clamping lever 22 from the case 23 the tensioning device 20 be separated.

The 11 and 12 show another system for tensioning a side curtain on a commercial vehicle body, the system comprising a winding shaft 10 and a tensioning device 20 having. The winding shaft 10 has, preferably exclusively, a tension tube 12 on. The tension tube 12 is in a connecting sleeve 11 taken, with the coupling sleeve 11 integral with a shaft journal 21 the tensioning device 20 is trained. In other words, the shaft journal 21 form a sleeve, which in the coupling position of the winding shaft 10 an axial end of the tension tube 12 encloses.

To get a torque from the shaft journal 21 on the tension tube 12 to be able to transmit, it is preferably provided that the shaft journal 21 a to the inner contour of the clamping tube 12 has complementary contour ( 12 ). The tension tube 12 so can from above into the coupling sleeve 11 are inserted, wherein the shaft journal, which is integral in the coupling sleeve 11 is formed in the inner contour of the clamping tube 12 intervenes. This is a positive connection between the shaft journal 21 and the tension tube 12 created.

The shaft journal 21 is part of the tensioning device 20 which is essentially a to the embodiment according to 4 to 6 having identical structure. The tensioning device 20 includes a housing 23 that is substantially U-shaped. Specifically, the housing faces 23 a lower bearing leg 23a , an upper bearing leg 23b and a connecting bridge 23c on. The upper bearing leg 23b and the lower bearing leg 23a are aligned substantially parallel to each other. The connecting bridge 23c connects the bearing legs 23a . 23b , Furthermore, the connecting web is used 23c to do this, the tensioner 20 or the housing 23 with a commercial vehicle body, in particular a corner stanchion 30 of commercial vehicle construction, to connect. The tension lever 22 extends between the bearing legs 23a and 23b and is in the case 23 pivoted.

The tensioning device also has a release lever 22c on, the mechanical with a locking element 22b connected is. The locking element 22b engages in a gear 22a one. With the release lever 22c can the locking element 22 be brought into a position in which the locking element 22b does not engage the gear 22a. In this way, the gear can 22a be released.
