15 20 25 30 2 furrows. These joint connections wear out quickly and the possibility of locking in the outer positions is lost and they can thus not be used as a single loaded joint.
O ﬁ a, it is therefore advantageous and desirable to be able to use a system that does not have these shortcomings.
The aim of the invention is to create a hinge joint and a method for twisting and locking, where the joint can be folded in a purposeful, reliable and simple way, through which the folded length is reduced and provides a better opportunity for placement of hoses and pipes without displacements. in the longitudinal direction during the swing. The design makes it possible to create a simple, strong and torsionally stable construction, where any play disappears in the outer positions.
The invention The invention is, as we mentioned earlier, a double hinge joint, which is unique in that it contains two or more toothed plates which are held together by a hinge part and which along a part of the edge have a circular arc of teeth which continues into a path. as a straight line with tooth engagement, where a main section and one or ytt your outer sections can be folded and locked and i xered in the outer positions.
The invention is thus a hinge joint which is to be used primarily in wide agricultural machinery, such as spreaders, hose barriers, harrows, down mills, drawbars, stabilizers, and which consists of a main section and one or more outer sections, where a hinge joint comprises: - a hinge part with at least two holes for passing through locking elements - at least two plates, each of which has at least one hole through which a locking element connects the plate to the hinge part, and where a part of the edge of the plates is toothed and where the toothed edges are engaged , and where a part of the edge of each plate which is toothed forms part of an arc of a circle which merges into an edge with teeth which follow a substantially straight line on one or both sides of the arc and where the plates with teeth engaged are movable in relation to each other and in relation to the hinge part, which is fixed in both plates, so that a frame in the main section and a frame in an outer section can be folded around the hinge hinge.
The hinge joint consists of fittings, on which one or more of your plates are fixed, where at least a part of the edge of the plate is toothed and where the part of the edge of the plate that is toothed forms part of an arc of a circle, which at one or both ends merges into a virtually straight line, and where the teeth in engagement are movable relative to each other in the positions where the teeth cease. The hinge joint can be designed as a double hinge joint. The term "toothed" in this context means that the edge of the plate is provided with teeth as on a gear without the plate being a gear (with a circular shape and teeth along the entire edge).
The inventive design of the hinge joint makes it possible to lock the hinge in an advantageous and expedient manner by the toothed part of the plate edge, which constitutes a substantially straight line, acting as a stop stop. When the teeth of two straight edge pieces are in full engagement, the joint can not be turned around any more, which means that the joint cannot be overloaded.
The plates have a largely rectangular or trapezoidal shape, except that one corner is rounded like an arc of a circle. About half or 40-60% of the edge of the plate is serrated, including the edge with the circular arc and the smallest one toothed part with a virtually straight line. A part of the edge that is not toothed may be provided with a bracket for mounting the plate on a frame. The fitting can be welded or screwed to the plate. The plate is mainly made of steel, especially hardened steel, but other materials with similar properties are also used. The part of a plate edge that is not toothed is connected to a bracket for mounting on the frame in the main section or the outer section.
The hinge part has at least two holes for locking elements such as rivets or screws and in a recommended embodiment the hinge part comprises at least three holes, where the third hole can be connected to an actuator, which at its other end can be connected to the frame in the main section or outer section. Although the hinge joint can in principle be operated manually, it is recommended that it be operated mechanically with an actuator, for example a hydraulic cylinder.
In an embodiment of the hinge joint, which is suitable for use in, for example, a boom with a high load, a first actuator is attached to the frame in the main section and a second actuator is attached to the frame in the outer section, where the first and second actuators cooperate with the hinge member. In this way, the joint part is affected by two actuators and thus has double force.
According to the invention, the hinge joint also comprises an embodiment where it consists of an additional hinge part. When the hinge joint comprises two hinge parts, the two hinge parts can be placed on each side of two plates and hold the plates together by means of screws or rivets.
An embodiment of the hinge joint where the serrated edges can be adjusted to include ﬂ your extreme positions can be produced. The outer positions are usually where the teeth on the edges end.
In a recommended embodiment, the hinge joint comprises four plates, which constitute two pairs of plates which are identical in pairs and mounted in pairs parallel to the joint part.
With this embodiment, a very strong and torsionally stable construction is achieved. According to the invention, the hinge joint can be turned to the left or right, which means that it can be adapted for use in most tools, e.g. bommar. In a system with a boom, there can be folding joints which have hinges in accordance with the invention and which can either be turned to the left or to the right.
In an embodiment of the invention, two hinge joints can be mounted in a folding joint. This is used, for example, on trailer hose booms where it may be necessary to have hinge joints in both top and bottom frames. The two hinge joints can be the same or different.
In accordance with the invention, an actuator in the form of a hydraulically driven cylinder or an electrically driven spindle is recommended. A hydraulically driven actuator is especially recommended, as such an actuator is very efficient.
In a recommended embodiment of the double hinge joint in accordance with the present invention, the toothed arc corresponds to approximately a quarter circle. In conjunction with a straight toothed piece on one side or both sides of the arc of a circle, the gait joint can thus be pivoted up to 90 degrees or 180 degrees.
When the arc of a circle has a straight piece with teeth at both ends, the angle between the straight pieces is mainly about 90 degrees.
In an embodiment of the hinge joint, the toothed edges can be adjusted so that they comprise ﬂ your outer positions. In this way, it is possible to adjust how much the main section and the outer section can be folded in relation to each other. It is thus possible to adjust the tilt to between, for example, 90 and 180 degrees.
It is also possible to adjust each end stop, e.g. with the locking points of the actuator on the hinge part or with the travel of the steel actuator, if the actuator is, for example, a linear hydraulic cylinder.

Detailed description Figure 1 shows a known hinge joint 1, where the discs 2a and 2b, which are in principle circular, have been clamped around the part 3 by means of the shaft 6, which passes through the holes in the discs 2a and 2b and the frame part 3. The discs 2a and 2b are both connected to an arm 4, which in turn is connected to one end of the actuator 5, if the other end is fixed to the frame part 3. When the actuator 5 is displaced, the arm 4 is actuated and performs a rotational movement of the discs 2a and 2b around the shaft 6. Thus, the fittings 7 on the discs 2a and 2b are forced to perform a rotating movement, so that the angle between the frame part 3 and the fittings 7 is changed.
Figure 2 shows the known hinge joint 1 from Figure 1 mounted on a spreader boom 20 with a trailing hose system, where the spreader boom is in the extended position. The spreader boom consists of two sections 21 and 22, which can be folded relative to each other.
The folding takes place by means of the hinge joint 1, which is mounted with the frame part 3 on the section 21 and the fittings 7 on the section 22. The hinge joint 1 can be influenced by the actuator 5 so that section 22 folds in relation to section 21 on the spreader boom.
The situation where the spreader boom 20 is in the folded position is shown in Figure 3. Here, the section 22 is completely folded to the section 21 via the hinge joint 1.
Figure 4 shows a manure spreader 30 mounted on a trolley with manure container 31.
The trailer can be towed by a tractor 32 or similar vehicle. A number of spreader elements 33 are mounted on the manure spreader 30, which consists of an inner section 34 which is connected to two outer sections 35a and 35b. The outer sections 35a and 35b can be folded against the inner section 34 by means of the hinge joints 36a and 36b. 10 15 20 25 30 8 Figure 5 shows an embodiment of the hinge joint 40 in accordance with the invention.
The hinge joint 40 is shown in a section A, where it is located on the boom 41.
The hinge joint 40 comprises a hinge part 42, on which four plates 43a, 43b, 43c and 43d are fixed with through-going screws 44. The plates 43a, 43b, 43c and 43d are two and two in pairs identical and mounted in parallel on each side of the hinge part 42. Each plate comprises a toothed edge portion 45, which is substantially in the shape of an arc of a circle. On each side of the edge portion 45 extend the toothed edge portions 46 and 47, which extend in substantially straight lines. Approximately half of the edge of the plates 43a, 43b, 43c and 43d is serrated. A part of the edge without teeth is connected to the fittings 48a and 48b, which are mounted on the frames 49 and 50. These frames are located in the main section and one outer section on the boom 41, respectively.
The hinge part 42 is further connected to an actuator 51, which is a linear hydraulically driven actuator in the form of a hydraulic cylinder. The actuator 51 is connected at one end to the hinge part 42 and at the other end to the frame 50.
Figure 5 shows the hinge joint 40 in the position where the boom 41 is fully extended. In this position, the serrated edges of the piece 47 engage each other and lock the boom in the extended position.
In Fig. 6, the actuator 51 has moved the hinge part 42 so that the plates 43a, 43b, 43c and 43d engage the toothed parts of the edge 45, which have the shape of an arc of a circle.
In this position the boom 41 with the hinge joint 40 is half extended. The corresponding circular arcs 45 with teeth which are in engagement with each other and the boom and the outer section together form an angle of about 90 degrees.
Figure 7 shows the hinge joint 40 in a position where the boom 41 is in the folded position. Here, the hinge part 42 ﬂ has been further flattened by the actuator 51 so that the toothed edge part 46 is engaged. The teeth of the edge portion 46 follow a substantially straight line. The boom and the outer section now together form an angle of about 180 degrees.
Figure 8 shows a boom with two sections, which are held together by two hinge joints in accordance with the invention. The boom is mounted with a hinge joint 60 with a hinge part 61, on which four plates 62 are fixed. Hinge joint 60 is mounted on the frames 49 and 50 with the fittings 63. Hinge joint 60 is connected to actuators 64, which can cause the hinge joint ﬂ to be flattened so that the frames 49 and 50 can be folded.
This is shown in Figure 8b and Figure 8c. Figure 8a shows hinge joint 60, with frames 49 and 50 unfolded.
The boom comprises a further hinge joint 70, which consists of two hinge parts 71, between which two plates 72 are mounted. Hinge joint 70 is mounted on the frames 49 and 50 with the fittings 73. Hinge joint 70 is not connected to an actuator and therefore follows the movements from hinge joint 60. Therefore, the joint end 71 is also referred to as a subordinate joint.
In the same way as with hinge joint 60, hinge joint 70 is shown with the frames 49 and 50 unfolded in ﬁ gur 8a and folded in ﬁ gur 8b and 8c.
Hinge joints 60 and 70 are shown with your details in the following 10 clocks 10 and 11.
Figure 9 shows an embodiment of a hinge joint 80 in accordance with the invention, which is mounted on two frames 49 and 50. In this embodiment, the hinge joint 80 is connected via hinge part 81 to two actuators 84 and 85, which are connected at opposite ends to the frames 49 and 50. This embodiment is particularly suitable for heavier machines.
Figure 10 shows details of a hinge joint 60 shown in Figure 8. The hinge joint consists of four plates 62, which are fixed in pairs in fittings 63 so that the plates 62 are generally parallel. Between the plates 62 the hinge part 61 is inserted. The hinge part 61 is provided with two holes 64, which correspond to the holes 65 in the plates. Through the holes 64 and 65, the screws 66 can be inserted, which rotatably attach the plates 62 to the hinge part 61.
The hinge part 61 is provided with a third hole 67 on an arm 68. The hole 67 is used to fasten an actuator. Approximately half of the edge of the plates 62 is toothed and is otherwise designed as described in Figure 5.
Figure 11 shows an embodiment of the hinge joint 70. The hinge joint 70 comprises two plates 72 with teeth on a part of the edge, where the teeth are engaged. The plates 72 are held together by means of hinge part 71 with the holes 74, which correspond to the holes 75 in the plates 72, through which the screws 76 have been inserted and locked at the ends with the nuts 77.
The plates 72 are attached along an edge to fittings 73, so that the hinge joint 70 can be mounted in a boom. Also in this case, approximately half of the edge of the plates 72 is toothed and is otherwise designed as described in Figure 5.
