    Device for attaching an accessory to a towbar
    BACKGROUND OF THE INVENTION
    The invention relates to a device for mounting an accessory on a towbar of a vehicle provided with a tow ball. The invention further relates to an assembly of such a device and an accessory, such as a bicycle carrier, a luggage carrier or a blocker for a rear door or flap of a vehicle.
    It is known to attach an accessory or additional auxiliary device to a towing hook of a vehicle, such as a bicycle rider, a luggage carrier or a door blocker extending into the pivotal path of a rear door or flap of the vehicle. Particular attention has been paid to the method of coupling the accessory with the towbar ball. There are many designs, such as with a vertical clamping action on the tow ball, between the top of the ball and the bottom edge of the ball. See, for example, NL 93.01797, FR 2.750.376, NL 87.02736 and NO 174.246, in which use is made of a tension bolt to be tensioned against the top of the tow ball. NL 1026760 shows a variant thereof, with a lever having at the end a pin which can be forced into a recess in the upper surface of the tow ball. In EP 0 710 588 the ball is engaged at the top along the edge and a lever is pulled against the lower edge of the ball by leverage.
    In other embodiments, the ball is clamped horizontally, see for example EP 1,095,820, NL 1024559, NL 1027082, NL 1038326 and NL 2009574. An accessory that is mounted on the ball by means of two half-shells, one of which is movable. known from WO 2007/036921.
    In NL 2004134 a device is shown with a vertical tube that is lowered from above over the ball until the lower edge of the tube comes to rest on a bracket mounted on the towbar neck. An accessory with transverse pins is then mounted on the sleeve, the pins extending below the ball. The attachment is then secured with a lock.

    In order to achieve at least one of these objects, the invention provides a device for mounting an accessory on a towbar of a vehicle provided with a tow ball, comprising - a holder for the accessory, - a housing - a sliding part - with which the housing is a defines first receiving space for the sliding part, wherein the sliding part forms a second receiving space for receiving the tow ball, wherein in use the sliding part can be displaced relatively up and down in mutually opposite first and second directions in the first receiving space, between an access position in which the second receiving space is accessible for the towing ball and a coupling position which is higher in use than the access position, wherein the towing ball is coupled to the device, the device further comprising one or more coupling elements which are relative to the sliding part and to the housing be movable between a passive position in the aforementioned access position and an active one the position in the aforementioned coupling position, imposed by the relative displacement of the sliding part relative to the housing. The coupling can hereby be established in a simple manner.
    In a further development thereof, the sliding part, in particular in the second receiving space defined by the sliding part, is provided with a first stop for stop facing in the second direction with a second stop provided on the towing hook, in particular on the towing ball , which second stop has one or more planes that have a normal with a directional component in the first direction, for relative displacement of the sliding part in the first receiving space in the first direction of the first receiving space access position to the coupling position when the housing is displaced relative to the towbar in the second direction. As a result, in a virtually continuous movement of placing the device downwards on the towing ball and then after the arrival of the first and second stops against each other, the relative displacement of sliding part and housing for realizing the coupling can be realized.
    In one embodiment, the one or more coupling elements are displaceable relative to the sliding part, preferably in directions transverse to the first direction, between the passive position outside the trajectory profile of the tow ball when the tow ball is introduced into the second receiving space and the active position in which they reach within that job profile.
    In one embodiment, in the relative displacement of the sliding part in the first direction, the housing forms a first operating element for imposing the displacement of the one or more coupling elements from the passive to the active position, the one or more coupling elements being arranged to pressing the active position against surfaces of the tow ball having a normal with a directional component in the second direction, in the coupling position of the sliding member.
    When the device is placed downwards over and over the draw ball, the draw ball will be put - relatively, the draw ball is in fact stationary - in the second receiving space with its largest diameter past the one or more (then still passive) coupling elements and the towing hook, in particular towing ball, with the first stop in contact with the second stop of the sliding part, after which when the housing is pressed further downwards, the sliding part in the first receiving space, within the housing will be forced relatively in the first direction and in that direction relative displacement of the sliding part (relative to the housing) an activation of the one or more coupling elements can take place which can then be active under the towing ball for coupling the device to the towing ball. Placing the device according to the invention is therefore a simple process.
    In one embodiment the sliding part forms a second operating element, preferably with a guide which is preferably transverse to the first direction, for guiding the one or more coupling elements in the displacement thereof between the passive and the active position thereof. The guide can form part of a third receiving space formed by the sliding part for each coupling element. The third receiving space can be provided with a threshold for stopping the relevant coupling element against falling out in a direction towards the second receiving space.
    In one embodiment the housing forms a fourth receiving space for each coupling element in its passive position. The fourth receiving space can be limited on the side of the sliding part by ramps which have a normal with a directional component in the second direction and a directional component towards the second receiving space. This provides space for the coupling element in its passive position in a simple manner. The run-on surfaces allow the coupling element in question to be forced inwards in the first direction relative to the housing when a force is applied thereto. The coupling element can be movable transversely of the first direction relative to the housing and, after leaving the fourth accommodation space, also in the first and second directions relative to the housing.
    The housing can delimit the fourth receiving spaces in a direction away from the second receiving space.
    In a simple embodiment the housing forms a third stop for keeping the coupling elements in the active position and the housing thus cooperates in keeping the one or more coupling elements in that position, which third stop preferably has a normal transverse to the first direction. The third stop can for instance be formed by an inner surface of the housing. In the active position of the one or more coupling elements, the third stop can define the third receiving space on the side thereof remote from the second receiving space.
    In one embodiment, the third and fourth receiving spaces are aligned with each other in the access position of the sliding part and are aligned with each other in the coupling position thereof.
    The coupling elements are preferably loose elements, such as rollers or balls, which are in particular rotatable about an axis parallel to the tangent line on the towing ball at the location of the contact between the coupling element concerned and the towing ball. The displacement of the coupling elements can hereby be promoted.
    In a simple embodiment, the sliding part forms a chamber with an upper wall, a bottom defining an access opening for the towing ball and one or more side walls. The side wall can form a circularly circumferential wall of the second receiving space. The sliding member can have an inner diameter or width of approximately 5 cm. The upper wall can form the first stop.
    The distance between the bottom of the top wall and the edge of the third receiving spaces closest to the top wall can be greater than about 2.4 cm.
    The distance between the underside of the top wall and the edge of the third receiving spaces furthest away from the top wall can be smaller than about 4 cm.
    In an embodiment which is favorable for stability, coupling elements operate viewed in a horizontal circumferential direction of the towing ball at a number of locations which are regularly spaced apart.
    To maintain the coupling position, the device according to the invention can be provided with a locking device for locking the slide part against displacement of the sliding part in the second direction. In a compact embodiment, the locking device can herein comprise a fourth stop with the sliding part forming a slidable whole, as well as a movable locking element, such as a pawl, which is displaceable between a locking position in operative connection with the fourth stop and a release position free thereof. For unauthorized unlocking of the device, it then comprises a lock for fixing the locking element, in particular pawl, in the locking position, the lock preferably comprising a resilient bolt. The pawl may be arranged inclined toward the release position. For this purpose, the pawl can for instance be provided with a weight which causes the pawl to tilt to the release position or, for example, be tensioned to the release position by a spring.
    Said fourth stop can be arranged on a rod, at the end of which the sliding part is mounted, which rod extends in the first direction.
    In one embodiment, the sliding member is biased to the access position. To that end, the device may comprise a spring for said bias, operating between a fifth stop fixed with the housing and a sixth stop fixed with the rod. The fifth and sixth stop can be located on the side of the fourth stop remote from the sliding part in the first direction.
    In one embodiment, the housing shields the first receiving space in all directions in horizontal directions.
    The housing is straight cylindrical in a simple and compact design. The cross-section thereof can be, for example, rectangular or circular.
    In a handy design, the housing is box-shaped and in use the first direction is vertically upward.
    In a simple embodiment, the sliding part can only be displaced along the first receiving space along a linear path.
    From a further aspect the invention provides a device according to the preamble of claim 1, wherein the sliding part, in particular in the second receiving space defined by the sliding part, is provided with a first stop turned in the second direction and the towing hook, in particular the towing ball is provided with a second stop with one or more planes that have a normal with a directional component in the first direction, for moving the sliding part in the first receiving space when the first and second stops engage with each other in the first direction of the access position to the coupling position, wherein the device further comprises one or more coupling elements which are movable relative to the sliding part and preferably also the housing, preferably in directions transverse to the first direction, between a passive position outside the path profile of the draw ball when inserting the draw ball into the second receiving space and an active position in which it reaching within that path profile, wherein the housing forms a first operating element in the relative displacement of the sliding part in the first direction for imposing the displacement of the one or more coupling elements from the passive to the active position, wherein the one or more coupling elements are arranged to press in the active position against surfaces of the towing ball which have a normal with a directional component in the second direction, in the coupling position of the sliding part.

    DETAILED DESCRIPTION OF THE DRAWINGS
    The device 1 of figure 1A comprises a hardened steel housing or tube 2 with an outer wall 2a which is rectangular in cross-section and a U-profile secured therein by bolts with opposing inner walls 2b and a wall 2c connecting this. The sleeve has a central axis S, here vertically, and a bottom opening 9. The sleeve 2 defines a first receiving space 30, in which are accommodated a sliding part 3, a support plate 7 fixed with the housing 2, a lock 14 and a locking catch 10. Alternatively, the sleeve 2 have an outer circle-shaped outer wall.
    The sliding part 3 is made of hardened steel and is inversely U-shaped, with an upper wall 16 and two hanging side walls 17, with which a second receiving space 31 with access opening 32 is determined. Each side wall 17 has a (third) accommodation space 18 which forms a radially through hole and is defined by edge 19 and is provided with a circumferential retaining edge 24 in the inward direction towards center line S.
    Near the lower end, the inner walls 2b of the housing 2 are provided with a number of (fourth) receiving spaces 21 which are radially oriented, diametrically relative to each other relative to the axis S and are bounded on the inside by beveled edges 22.
    The receiving spaces 21 and 18, see also figures 1B and 1C, offer space for loose ball-shaped coupling elements 20 which can move in directions F. These can be arranged regularly distributed in horizontal circumferential direction (with respect to the tow ball to be received), in a number of two or more, in particular more than two, if the second receiving space has a circular cross section. The receiving spaces 18 have a diameter that is just slightly larger than that of the balls 20, the retaining edges 24 have a smaller diameter, see figure 1B. The upper wall 16 defines a (first) stop surface 23 on the underside thereof. The sliding part 3 fits tightly within the inner walls 2b and can slide between them (first direction A) and down (second direction B), relatively.
    Mounted on the upper wall 16 of the sliding part 3 is a steel rod 4 which is slidable up and down with sliding part 3 in the first direction A and the second direction B. The rod 4 is thereby guided by the guide of the sliding part 3 within the inner walls 2b and in a guide hole 7a in the plate 7. Mounted on the rod is a ring 6 against which (sixth stop) supports the lower end of a compression spring 8, which compression spring 8 with the other end rests against support plate 7 (fifth stop) and can be pressed in / out in directions E. A ring 5 which is mounted on the upper end of the rod 4 ensures that the rod 4 cannot come downwards out of the guide hole 7a and thus that the sliding part 3 always remains inside the tube 2. Further functions of the spring are discussed below.
    The ring 6 also serves as a locking stop for the locking pawl 10. The locking pawl 10 is rotatable (directions C) about a pin 11 fixed with the sleeve 2 and has a pawl part 12 and a mass part 13 located on the other side of the pin 11, whereby the bolt latch 10 tends to a free position. This can also be achieved with a spring that extends between a fixed plate on the housing (on the drawing top right the shaft 11) and the pawl part 12. In addition to the pawl part 12, a lock 14 is provided, which is provided with an outwardly spring-loaded tongue 15 which can be retracted by turning a key in direction D.
    Figure 1C illustrates a tow ball 51 of a tow bar for illustrative purposes.
    Figure 2A shows a part of a tow bar 50 mounted on the gate of a motor vehicle. The tow bar 50 has a neck 52 and said tow ball 51. The tow ball 51 has a center line T and a flattened tip 53 forming a second stop. Alternatively, the ball 51 can be formed with a round top surface, which can then form the second stop. The ball 51 has a diameter of approximately 50 mm. The receiving space 31 has a width that is almost equal to it, so that the ball can be received in a suitable but slidable manner in the receiving space 31. The ball 51 has a convex bottom surface 54. A clamping piece 55 is mounted on the neck 52 by means of two bolts 57 wherein rotation about axis T is prevented by means of a set screw 56 with crater end which engages in the surface of the towbar neck.
    When placing the device 1, the sleeve 2 with its lower end and opening 9 and access opening 32 is brought straight above the stationary ball 51 and the sleeve is lowered onto / over the ball 51. The user has retracted the spring tongue 15 by operating (direction D) of the lock key. Figure 2A shows the moment at which the ball 51 entered through the access opening 32 in the receiving space 31 and the largest cross-sectional area of the tow ball 51 is still just below the balls 20. The center lines S and T can coincide (figure 1C).
    In Figure 2B, the ball 51 with the largest cross-section thereof has passed, upwards, the balls 20 into the receiving space 31. The top 53 has come against abutment surface 23 of sliding part 3. The balls 20 are still located in the receiving spaces 18 and 21 therefor, in the passive position. The pawl 12 lies next to the ring 6 under the influence of the mass part 13. It can also be seen that the clamping piece 55 also fits into the opening 9 and can enter the receiving space 30. The clamping piece 55 in opening 9 prevents rotation of the sleeve 2 about the axis T relative to the tow ball.
    The sleeve 2 is then further pressed downwards by the user, the sliding part 3 shifting relatively inside the sleeve 2 in the first direction A, guided by rod 4 and by inner wall 2b, 2c. The spring 8 is thereby depressed. With the relative shift of sliding part 3 relative to the inner walls 2b, the (lower edges 19) exert an upward force on the balls 20, which thereby run up along the beveled edges 22 of the receiving spaces 21 and are thereby forced radially inwards until the balls 20 have come completely out of the receiving spaces 21. Because the inner walls 2b move downwards relative to the sliding part 3, the balls 20 end up above the receiving spaces 21
    The pawl part 12 will end up under the ring 6, whereby the lock spring pressure can cause the tongue 15 to expand. The closing spring pressure overcomes the force of the mass part 13, whereby the pawl part 12 is forced under the ring 6.
    The user can then release the sleeve 2, with the result that the spring 8 can expand somewhat and the ring 6 with the underside, which forms a fourth stop, can press against the pawl part 12 with force. The situation of figure 3A has been reached, the coupling position. The locking catch 10 locks this coupling position. The ball 51 rests with convex surfaces 54 against the balls 20, which bear against the edges 19 and the inner surface of inner walls 2b, which inner surface forms a third stop for the balls. Lifting the device 1 away from the tow ball is hereby prevented. The clamping piece 55 has ended up in the opening 9, a short distance from the lower edge of sliding part 3, to prevent undesired tilting movement of the device 1 relative to the ball 51 and / or to prevent access of a breaking tool.
    Upon removal of the device 1, the user again operates the lock 14 to retract the tongue 15. By pressing on the sleeve 2 from above, because the sliding part 3 and thus the rod 4 are fixed in the vertical direction, the shaft 11 and thus the locking pawl 10 can be moved slightly downwards relative to the ring 6, so that the pawl part 12 is allowed to turn away clockwise under the influence of mass part 13 of locking catch 10, free of ring 6. The spring 8 can then relax and force the sliding part in the second direction B. The balls 20 thereby slide over the inner surface of the inner wall 2b until the situation of figure 2B is reached again. Then both balls 20 again lie in the receiving spaces 21 and 18, in the passive position, and the sleeve 2 can be lifted, whereby the tow ball 51 moves out of the sliding part 3, to a situation such as that of figure 2A.
    The device 1 can be narrow and compact. There are only a few rotating parts, which means trouble-free operation for a long time. The housing, such as the sleeve 2, shields the coupling elements, such as the balls 20, the sliding part and the locking parts from the surroundings, so that unauthorized persons cannot access them to manipulate or release them.
    The device according to the invention can be easy to handle and operate and can simply be placed on a towing ball by pressing down and simply, if authorized, can be detached therefrom again.
    The tube 2 can form a whole as a holder with an accessory, such as a bicycle rack or a doorway flap in the pivot path of a rear door or flap of a (car-extending door blocker).
    Alternatively, the sleeve 2 can serve as attachment of an accessory thereon, for example with a coupling pin extending into the sleeve, so that the accessory can be releasably mounted on the device 1.
    The inventions are in no way limited to the embodiments shown and described in the drawings and description. The above description is included to illustrate the operation of preferred embodiments of the invention, and not to limit the scope of the invention. Starting from the above explanation, many variations will be apparent to those skilled in the art that fall within the spirit and scope of the present invention. Variations are possible of the parts shown in the drawings and described in the description. They can be used separately in other embodiments of the invention (s). Parts of different examples can be combined with each other.
