Description

DESCRIPTION

ball joint

The invention relates to a ball joint for the transmission of forces and / or moments and components which can be produced with at least one ball joint according to the invention, according to the respective preambles of the independent claims.

From DE 199 16 556 A1 a universal joint of a floor cleaning appliance is known. The universal joint consists of a lower pivot axis, which is formed by bearing pins of a handle holder and an upper, perpendicular thereto arranged joint, which consists of a pivot axis with an associated pin. In the upper pivot axis rotatably engages the handle holder, which is stored as a result in the pivot axis. The other part of the pivot axis is formed by the upper part of the universal joint, to which the bearing journals are preferably integrally formed material.

In DE 20 2006 011 254 U1 a razor with a arranged at a front end of a handle blade block is shown. The connection of handle and blade block is made by a ball joint. The ball joint is designed as a clip connection, that is, the upper opening of the socket can be temporarily increased or reduced in diameter. In addition, there is a spring element between the blade block and the handle. The task of the spring element is, upon rotation of the

CONFIRMATION COPY Bell block around an axis parallel to the longitudinal axis of the handle through the ball joint axis leading back to the zero position of the Klingblocks.

A disadvantage of a universal joint or a universal joint, that despite the given torque transmission, a non-uniform motion from the drive axle to the output shaft. In a ball joint results in a quiet and smooth movement, but no torque transfer from the drive axle to the output shaft is possible.

The object of the invention is therefore to provide a joint with a quiet and smooth movement between the drive axle and output shaft is possible, at the same time a force and / or moment between the drive axle and output shaft is transferable. In addition, components that contain at least one ball joint to be created in which a smooth and smooth movement while transmitting torque between the drive and output shaft of the ball joint is possible.

The object is achieved according to the invention in that the ball-like element has at least one recess in which engages at least one engagement body of the pan and that the ball-like element is movably mounted in the pan.

It is advantageous that by means of the ball joint according to the invention, a force and / or a moment is transferable. Also, the ball joint can be disassembled according to the invention, so that it can be cleaned, for example, and / or can be used as a coupling. It is also advantageous that the ball joint according to the invention has fewer parts than a universal joint. In addition, the ball joint is a design advantage over other types of joints such as the universal joint. Also, by means of the ball joint according to the invention, a more harmonious, uniform movement relative to the universal joint feasible because the typical "gimbal error" is lower. According to the invention, the components of the ball joint, at least comprising a ball-like element, a pan, at least one engagement body, are preferably produced by means of a plastic injection molding process.

The ball-like element of the ball joint is preferably a disc, a ball, a disc segment or a spherical segment. The disk segment may, for example, be part of a disk, for example a three-quarter disk, or be made of a disk-like shape. Under a disc-like shape is for example a cake piece shape, a Frisbeeform or any other form to understand, which has a flat freeform surface in the manner of a disc. For example, the ball segment may be a hemisphere or may be of a spherical shape. Under a spherical shape is for example a teardrop shape, an egg shape or any other form to understand that has a curved freeform surface in the manner of a ball.

According to the invention it is further provided that the ball-like element is formed as a solid body. Alternatively, the ball-like element may also contain at least one recess. The recess is preferably formed according to the invention in the form of a dimple or in the form of a hollow. For example, a plurality of dimples are distributed on the surface of the spherical element in the manner of a golf ball. For example, the cavities are distributed in the ball-like member so as to maintain the shape of the ball-like member, but the core or part of the core is hollowed out. Alternatively or additionally, areas of the surface of the spherical element may also be hollowed out by the cavities. By means of the cavities and the dimples, for example, the weight of the solid body is reduced, which leads to mass savings, and / or the shape and shape, that is, the design of the spherical element is adapted in design.

According to the invention it is further provided that the spherical element consists of a part or can be assembled from several individual parts. The ball-like element has according to the invention at least one recess. It is envisaged that the recess tangentially around the circumference of the spherical element. rotates or tangentially sections around the circumference of the spherical element circulates. Instead of tangential circulation, radial circulation is also used as a term. In this case, a plurality of sections of recesses may overlap so that, for example, the recesses form a cross or any other shape, such as a loop shape or ellipse shape, in the spherical element. Also, the circulation is not necessarily provided according to the invention to the largest extent of the spherical element. For example, it is also possible that the depression is arranged only in a region of the spherical element, for example similar to the region of the iris of the human eye.

The shape of the cross section of the recess is preferably open in a semicircular, angular and / or in the direction of the center of the spherical element in the bottom of the recess. According to the invention, the recess is preferably designed in the manner of a groove. Alternatively or additionally, the shape of the cross section of the depression can also be any other shape, for example a spherical and / or angular free-form surface. According to the invention, it is further provided that the shape of the cross section of the depression changes over its circulation, so that at least one rib and / or at least one depression forms in the depression. According to the invention, at least one engagement body engages in the depression. The shape and dimensions of the engagement body, which engages in the recess, is designed adapted to the dimensions of the recess and the shape of the recess. Alternatively, the engagement body, which engages in the depression, also touch the depression only in certain places, so that it is possible for punctiform and / or planar contact of the depression with the engagement body in partial regions of the depression to be possible. Preferably, the part of the engagement body which engages in the recess, a round shape, preferably a cylindrical shape or a hemispherical shape on. If the shape of the cross section of the recess of the spherical element changes over the circulation, it is possible, a detent adjustment of the spherical Element on engagement of the engagement body to perform in the recess, since the engagement body engages in the respective ribs or in the respective depressions in the recess.

In the four figures, preferred embodiments are explained in more detail according to the invention:

FIG. 1 illustrates a ball and cup with engagement bodies prior to assembly into a ball joint;

FIG. 2 shows a ball and socket joint according to the invention, which, as a spherical element, has a ball,

Figure 3 illustrates a disc and a cup with engagement bodies prior to assembly into a ball joint, and

FIG. 4 shows a plate on which a ball joint is fixed,

In Figure 1, a ball joint 1 is shown, comprising a ball-like element in the form of a ball 2.1, a pan 3, at least one engagement body 4, in the example two engagement body 4, and a lid. 5

The ball 2.1, which is the joint body is executed in the example as a solid body having a recess which is designed in the manner of a groove 6 has. The groove 6 is in the embodiment of Figure 1 sections tangentially around the circumference the ball 2.1 circulating, since the drive shaft, which is formed in the form of a handle 7, the circulation of the groove 6 interrupts. The handle 7 is fastened to the ball 2.1 with a suitable connection, for example with a connection with a round or angular shape, for example a polygonal shape in the form of a cuboid. The shape of the cross section of the groove 6 may be semicircular, angular and / or open in the direction of the center of the ball 2.1 in the bottom of the groove 6.

The pan 3 of Figure 1 includes a lid 5 which is positionable and fixable in the bottom of the pan 3. As a result, the positioning of the ball 2.1 in the pan 3 is easy and quick to carry out by the ball 2.1 can be inserted through the lid opening in the pan 3. The ball 2.1 is then detected by means of the lid 5 in the pan. The cover 5 is also removable, for example, for cleaning purposes of the ball joint 1.

The pan 3 contains in the example four recesses 8 in order to increase the freedom of movement of the ball 2.1 in the pan 3. Between the recesses 8 are receptacles 12, in the example four receptacles 12, arranged in the manner of a crown. The receptacles 12 are part of the pan 3 and arranged perpendicular to the bottom of the pan 3. The pan 3 is part of a connection, which is due to the round shape of the pan 3, for example, a cylindrical or tubular connection.

In the example of Figure 1, two engagement body 4 are fixed to the pan 3, that is, for example, secured with an adhesive connection in the pan 3.

The shape and dimensions of the respective engagement body 4, both of which engage in the groove 6 of the ball 2.1, the dimensions of the groove 6 and the shape of the groove 6 is designed adapted. The length of the respective engagement body 4 is adapted to the dimensions and the shape of the groove 6. Also, the two engagement body 4 are fixed to the pan 3, so that they engage in the groove 6. The engagement of the engagement body 4 takes place in the groove 6 radially relative to the ball 2.1. In the example of Figure 1, each of the two engagement body 4 has a hemispherical shape. The part of the respective engagement body 4, which is positionable on the pan 3 and does not come into direct engagement with the groove 6 of the ball 2.1, has a planar shape in the example according to FIG. This planar shape can be seen on the outside of the pan 3 of Figure 1.

The pan 3 as a total component of Figure 1 thus has four parts, namely the lid 5, the pan 3 and the two engagement body. 4

FIG. 2 shows an assembled ball joint 1. The same components are provided with the same reference numerals and new components are provided with new reference numerals.

The ball 2.1 of the ball joint 1 is inserted through the bottom of the pan 3, which has the lid 5, in the pan 3 and positioned in this for at least one movement. In this case, the pan 3 positioned above and below the center of the ball 2.1, the ball 2.1, so that the ball 2.1 is movably mounted in the pan 3 and is encompassed by the four receptacles 12. This also prevents leakage of the ball 2.1 from the pan 3. The lid 5 is removed from the bottom of the pan 3 for the process described above.

The transmittable by means of the handle 7 on the ball 2.1 linear movements 9, 10 and / or portable rotatotorische movement 11 allow the pan 3 moves to match the linear movements 9, 10 and / or the rotational movement 11. In this case, preferably at least one force is transmitted in the direction of at least one of the linear movements 9, 10 and / or at least one moment in the direction of the rotary movement 11 from the handle 7 to the pan 3 by means of the ball 2.1. By the two engagement body 4 in the pan 3, the force and / or the moment of the handle 7 are transmitted directly from the groove 6 of the ball 2.1 on the pan 3 by means of the engagement body 4. The round geometry of the ball 2.1 ensures a smooth movement. In addition, the position of the handle 7 in the pan 3 can be adjusted by means of the ball 3 mounted in the pan 2 so that, however, the linear movements 9, 10 and / or the rotational movement 11 continue to be transferable from the handle 7 to the cup 3 by means of the ball joint 1, but the axes of the engaging force and / or moment are of their original position changed.

FIG. 3 shows a further embodiment of a ball joint 1 according to the invention. The same components are provided with the same reference numerals and new components are provided with new reference numerals. The ball joint 1 has, according to FIG. 3, a ball-like element in the form of a disk 2.2, a pan 3, at least one engagement body 4, in the example two engagement bodies 4, and a cover 5. The structure and function of the pan 3, the two engagement body 4, the handle 7 and the lid 5 of Figure 3 is identical to the embodiment in Figure 1 and Figure 2.

The disc 2.2, which is the joint body, is designed in the example in the manner of a flat plane in a round disc shape. The disk 2.2 has according to Figure 3, a recess which is designed in the manner of a groove 6, on. The groove 6 is in the embodiment of Figure 3 sections tangentially around the circumference of the disc 2.2 circumferentially, since the drive shaft, which is formed in the shape of the handle 7, the circulation of the groove 6 interrupts. The shape of the cross section of the groove 6 may be half round, angular and / or open in the direction of the center of the disc 2.2 in the bottom of the groove 6.

The pan 3 of Figure 1 includes a lid 5 which is positionable and fixable in the bottom of the pan 3. As a result, the positioning of the disk 2.2 in the pan 3 is simple and quick to carry out by the disk 2.2 can be inserted through the lid opening in the pan 3. The cover 5 is also removable, for example, for cleaning purposes of the ball joint 1.

The pan 3 contains in the example of Figure 3 and four recesses 8 in order to increase the freedom of movement of the disc 2.2 in the pan 3.

The shape and dimensions of the respective engagement body 4, both of which engage in the groove 6 of the disc 2.2, the dimensions of the groove 6 and the shape designed the groove 6 adapted. The length of the respective engagement body 4 is adapted to the dimensions and the shape of the groove 6. Also, the two engagement body 4 are fixed to the pan 3, so that they engage in the groove 6. The engagement of the engagement body 4 takes place in the groove 6 radially relative to the disc 2.2.

FIG. 4 shows two variants A, B of an embodiment according to the invention. The same components are provided with the same reference numerals and new components are provided with new reference numerals.

In variant A, a ball joint 1 is shown, which is fixed to a two-dimensional part, in the example on a plate 13. The joint body, in the example a ball 2.1, is encompassed according to FIG. 4 of four receptacles 12 of a pan 3. In the ball 2.1, or in the groove 6 of the ball 2.1, engage in the example, two engagement body 4 according to the invention (not shown). Furthermore, a handle 7 is fixed to the ball 2.1. As a result of the engagement of the two engagement bodies 4 in the groove 6 of the ball 2.1, an axis 14 is formed around which the ball 2.1 and thus also the handle 7 can pivot or move. This makes it possible according to the invention that the handle 7 can pivot between the four recesses 8 of the pan 3 respectively. Alternatively, the handle 7 can also pivot through 360 °, when the handle 7 is located above the receptacles 12 relative to the plane of the plate 13.

The movements of the handle 7 are in each case suitable with the help of the ball joint 1 on the plate 13 transferable. In this case, two coordinate axes, a coordinate axis in the longitudinal direction L and a coordinate axis in the transverse direction Q are shown, which represent two possible directions of movement of the plate 13, shown in Figure 4. It is possible according to the invention, the plate 13 in the coordinate system, which is formed from the coordinate axis in the longitudinal direction L and the coordinate axis in the transverse direction Q, to move arbitrarily. A movement in the third spatial component, ie in the direction of the normal of the flat plate 13, is also possible by the handle 7 a movement with a vector in the direction performs the normal of the plate 13 and thus this movement is transmitted by means of the ball joint 1 on the plate 13.

In the following, the use of the handle 7, the ball joint 1 and the plate 13 in a floor cleaning appliance will be briefly described. The four receptacles 12 of the pan 3 are arranged on the plate 13 so that they have a possible optimal arrangement for the use described by way of example. The arrangement of the four receptacles 12 in variant A is inclined in each case by 45 ° relative to the two coordinate axes in the longitudinal direction L and transverse direction Q, so that an arrangement according to FIG. 4 results

It is conceivable for a cleaning device, for example, that the plate 13 consists of two parts, which are connected to each other by means of a hinge which has an axis for flipping the two parts. This makes it possible, for example, to clamp a cleaning cloth around the plate 13, which is a cleaning cloth holder in the example described, in a simplified manner, for example by changing the shape of the plate 13 for tensioning the cleaning cloth around the plate 13 with the aid of the joint (not shown). , For this purpose, the two parts of the plate 13 fold together with the help of the joint and after the re-clamping with the cleaning cloth then apart again, so that then a flat plate 13 results, around which a cleaning cloth is stretched. After the clamping of the plate 13 with the cleaning cloth, the plate 13 is verrasted and / or detected, so that there is a single flat, completely formed plate 13 of Figure 4.

The handle 7, as described above, can each be pivoted into the recesses 8, so that it is thus possible to move the plate 13 with the cleaning cloth with the help of the handle 7 under, for example, a living room cabinet for cleaning purposes, since the handle 7 almost flat can be placed on the plate 13. As exemplified in variant A of Figure 4, for example, a movement in the coordinate axis in the longitudinal direction L is easy to carry out when the handle 7 is inserted flat on the plate 13 in the recess 8 shown in Figure 4. Due to the shape of the recess 8, the movement of the handle 8 is additionally limited, since the handle 7 can move according to Figure 4 only in the region of the recess 8 when the handle 7 is inserted into this. Variant B of FIG. 4 differs from variant A in that the four receptacles 12 of the cup 3 are each aligned in the two coordinate axes in the longitudinal direction L and the transverse direction Q in the coordinate system on the plate 13.

Alternatively, it is also conceivable that only two receptacles 12 in combination, i. as a couple, to be used. This is indicated in Figure 4, characterized in that two receptacles 12 are shown with a dashed line and two receptacles 12 with a solid line. This results in two possible pairs of receptacles 12, over which with the help of engaging bodies 4, a ball-like element, such as a ball 2.1, can be moved in a pan 3. The respective pairs of receptacles 12 may alternatively each have only one common engagement body 4.

Due to the respectively changing arrangement of the receptacles 12 when using one of the two exemplarily selected possible pairs of receptacles 12 (dashed or un dashed shots 12), the possibility of movement of the handle 8 is additionally changed since the handle 7 is shown in FIG only in the respective resulting recess 8 can move.

Depending on the application in which a ball joint 1 according to the invention is used, an arrangement according to variant A or B according to FIG. 4 is to be preferred. Alternatively, the arrangement of the at least one receptacle 12 can also take place in any other arrangement in the coordinate system, if this requires the respective application.

Various components preferably contain at least one ball joint 1 according to the invention: a) cleaning device,

b) cosmetic or hygiene appliance, c) model model, preferably helicopter, car and / or ship, d) technology model, preferably in the manner of a modular system, e) simple, separable coupling to external equipment, preferably in tractors,
