Description

Arrangement of a Flap on a Body of a Vehicle The invention relates to an arrangement of a flap on a body of a vehicle.
Arrangements of flaps on bodies of vehicles, in particular commercial vehicles, are well-known from the general prior art. For example, the body is configured as a so-called load body which comprises a loading platform on which goods to be conveyed can be arranged. At least one flap is arranged on the body, wherein the flap is pivotably arranged on the body between a closed position and at least one open position. In the closed position at least a portion of the body is covered by the flap. In the open position, said portion is uncovered so that goods can be arranged on the body or in the body via the uncovered portion. For example, the flap is a door. In the closed position a loading area of the body is bounded at least partially by the flap so that goods arranged on the body are restrained and prevented from falling off the body by means of the flap being in its closed position. Said loading area is also referred to as a cargo area. In order to remove the goods from the body or the loading platform the flap is moved into its open position.
US 6 120 080 A shows a springing up apparatus for a door of a cargo box of a van-type truck in which the cargo box is formed on an upper portion of a truck bed.
It is an object of the present invention to provide an arrangement of a flap on a body of a vehicle in which arrangement the flap can be moved by a person in a particularly easy
and comfortable way.
This object is solved by an arrangement having the features of patent claim 1.
Advantageous embodiments with expedient developments of the invention are indicated in the other patent claims.
The invention relates to an arrangement of a flap on a body of a vehicle, in which arrangement the flap is pivotably arranged on the body between a closed position and at least one open position. This means the flap is pivotable between the open position and the closed position in relation to the body. For example, in the closed position at least a portion of the body is covered by the flap, wherein said portion is uncovered in the open position. For example, at least a portion of a cargo area or loading area is bounded by the flap when in the closed position. In the open position said portion of the loading area not bounded by the flap so that, for example, goods to be conveyed can be arranged on or unloaded from the body via the uncovered portion. Preferably, the body comprises a loading platform by means of which said cargo area is bounded in the vertical direction of the vehicle towards the bottom.
Moreover, in said arrangement at least one cam is arranged on the flap at least indirectly.
Preferably, the cam is arranged on the flap in a rotationally fixed manner. The arrangement further comprises at least one spring element which is attached to the cam The spring element is attached to the body at least indirectly. Moreover, the spring element is configured to be loaded by moving the flap from the closed position into the open position. Furthermore, the spring element is configured to exert a spring force on the flap in the open position thereby holding the flap in the open position. In other words, the flap is held in the open position by means of the spring force exerted on the flap at least indirectly by means of the loaded spring element. Additionally, the spring element is configured to exert a spring force on the flap when moving the flap in the closed position thereby supporting the movement of the flap into the closed position. For example, when a person such as the driver of the vehicle moves the flap out of the open position in the direction of the closed position the spring element exerts a spring force at least indirectly on the flap so that the movement of the flap in the direction of the closed position is supported by the spring force and, thus, the spring element. Thus, the person can move the flap into the closed position in a particularly easy and comfortable way. Furthermore, the movement of the flap into the open position and, thus, the event of loading the spring can be supported by the weight of the flap so that the flap can be moved into the open position particularly easily and comfortably by the person.
For example, the spring element is configured as a simple helical tension spring so that the complexity and costs of the arrangement according to the present invention can be kept particularly low. Since the movement of the flap is supported, a particularly low human effort for moving the flap which is configured as, for example, a door is required.
Moreover, human fatigue caused by moving the flap can be avoided.
Further advantages, features, and details of the invention derive from the following description of a preferred embodiment as well as from the drawing. The features and feature combinations previously mentioned in the description as well as the features and feature combinations mentioned in the following description of the figures and/or shown in the figures alone can be employed not only in the respective indicated combination but also in any other combination or taken alone without leaving the scope of the invention.
The drawing shows in: Fig. 1 part of a schematic and perspective rear view of an arrangement of a flap on a body of a vehicle, in which arrangement the flap is pivotably arranged on the body, wherein the flap is in its closed position; Fig. 2 part of a schematic and perspective side view of the arrangement according to Fig. 1; and Fig. 3 part of a schematic and perspective side view of the arrangement, wherein the flap is in its open position.
In the figures the same elements or elements having the same function are indicated by the same reference signs.
Fig. 1 shows an arrangement of a flap 10 on a body 12 of a vehicle in the form of a commercial vehicle. For example, the body 12 is designed as a tipper body which is movably held on a frame of the vehicle. For example, the body 12 is pivotable about at least one pivot axis in relation to the frame. Alternatively, the body 12 can be designed as a rigid body or a cargo body or load body. The body 12 comprises a loading platform 14 on which goods to be conveyed can be arranged. The loading platform 14 has a loading surface 16 on which the goods to be conveyed can be arranged. The body 12 comprises lateral walls from which one lateral wall 18 can be seen. Said lateral walls bound a loading area 20 of the body 12 in the transverse direction of the vehicle. The loading area 20 is also referred to as a cargo area which is bounded by the loading platform 14 in the vertical direction of the vehicle towards the bottom. For example, the wall 18 is also referred to as a side wall being configured as a flap which is pivotably arranged on the loading platform 14. The lateral walls are also referred to as side panels.
The flap 10 is a rear flap which is also referred to as a rear door, tail door or tail flap, the flap 10 being pivotably arranged on the body 12, in particular the loading platform 14 at least indirectly. Moreover, the body 12 can comprise a front panel which cannot be seen in Fig. 1, the front panel being attached to the loading platform 14. The loading area 20 is bounded by the front panel in the longitudinal direction towards the front.
The flap 10 is pivotably arranged on the body 12 about a pivot axis which extends in the transverse direction of the vehicle. The flap 10 can be pivoted between a closed position shown in Figs. 1 and 2, and at least one open position shown in Fig. 3. In the closed position the flap 10 bounds the loading area 20 in the longitudinal direction of the vehicle towards the back. In the open position the loading area 20 is not bound by the flap 10 30 that a portion of the loading area 20 is uncovered. Hence, goods to be conveyed can be arranged in the loading area 20 via said uncovered portion. In the closed position, said portion of the loading area 20 is covered by the flap 10 so that goods arranged on the loading platform 14 are restrained and prevented from falling off the loading platform 14 by means of the flap 10.
Said arrangement further comprises at least one cam 22 (Fig.2) which is also referred to as a cam block. The cam 22 is arranged on the flap 10. In the present case, the cam 22 is arranged on the flap 10 in a rotationally fixed manner at least indirectly so that the cam 22 rotates together with the flap 10 when the flap 10 is pivoted between the open position and the closed position. For example, the cam 22 is attached to a hinge 24 which in turn is attached to the flap 10.
Moreover, the arrangement further comprises a spring element 26 in the form of a helical spring which is configured as a helical tension spring. The spring element 26 is attached to the cam 22 at a connection point 28 which is eccentric to the pivot axis of the flap 10 and, thus, the cam 22.
Moreover, the spring clement 26 is attached to the body 12 at least indirectly. As can be seen from Fig. 2, one end of the spring element 26 is connected to the hinge 24 through the cam block (cam 22). For this purpose, a pin 30 is attached to the cam 22, wherein a connecting bracket 32 is pivotably connected to the pin 30 on one side. On the other side, the connecting bracket 32 is connected, in particular pivotably connected, to the spring element 26 so that the spring element 26 is connected to the cam 22 via the connecting bracket 32 having two consecutive arms 34 and 36 extending angularly in relation to each other. On the other end the spring element 26 is connected to a spring bracket 38 which is attached to the body 12, in particular the loading platform 14.
An adjustable hook 40 is movably arranged on the spring bracket 38, wherein the spring element 26 is attached to the hook 40. For example, the hook 40 can be moved in relation to the spring bracket 38. By moving the hook 40 in relation to the spring bracket 38 a pre-stressing of the spring element 26 can be adjusted. As can be seen from Figs. 2 and 3, the spring element 26 is configured to be loaded by moving the flap 10 from the closed position into the open position. Moreover, the spring element 26 is configured to exert a spring force on the flap 10 in the open position thereby holding the flap 10 in the open position. Thus, at the fully opened condition of the flap 10 the spring element 26 is designed to hold the flap 10 and prevent it from bouncing back. Additionally, the spring element 26 is configured to exert a spring force on the flap 10 when moving the flap 10 into the closed position thereby supporting the movement of the flap 10 into the closed position. As the flap 10 is opened by, for example, a person, the upper hinge 24 rotates along with the cam 22 which in turn pulls and, thus, loads the spring element 26. When the flap 10 is being closed, spring energy stored in the spring element 26 is released thereby pulling up the flap 10.
Preferably, the spring element 26 is configured as an over-center spring which. In the open position of the flap 10 the spring element 26 exerts a first torque on the flap 10 about the pivot axis of the flap 10 in such a way that the flap 10 is held in the open position by means of said first torque. Said first torque acts in a first direction of rotation.
When the flap 10 is moved out of the open position in the direction of the closed position the spring element 26 is moved into and beyond its dead center so that the spring element 26 exerts a spring force on the flap 10, said spring force effecting a second torque on the flap 10 about the pivot axis of the flap 10 in such a way that the movement of the flap 10 in the direction of the closed position is supported. This means the second torque acts about the pivot axis in a second direction of rotation, the second direction of rotation being opposite to the first direction of rotation.
Thus, the person can open and close the flap 10 in a particularly easy and comfortable way sot that fatigue of the person can be avoided. Moreover, an enhanced life of the flap 10 can be realized. Furthermore, partitions in the lateral walls can be avoided.
Additionally, complex structures can be avoided and a weight reduction of the flap 10 as well as lateral walls can be realized since center pillars can be avoided. Additionally, locks can be avoided or the number of locks can be reduced. The concept shown in Figs. 1 to 3 can be applied to tail doors and side doors which are also referred to as drop side doors.
Single side walls can be used thereby reducing weight of center pillars and number of locks. For example, an approximate force of 300 N which is required to operate conventional flaps can be reduced to an approximate force of 30 N since the movement of the flap 10 is supported by the spring element 26.
