Description
Jockey Wheel Assembly The present invention relates to a jockey wheel
assembly, in particular to a jockey wheel assembly for a caravan or other trailer and to a jockey wheel kit and parts for making such an assembly.
It is common practice to have a jockey wheel assembly attached to a towing hitch at the front of a caravan to support the front end of the caravan when the caravan is unhitched from a towing vehicle. Such a jockey wheel assembly often comprises a wheel attached to an elongate body member. The body member is typically attached to the towing hitch using a bracket. The jockey wheel is raised or removed when the caravan is being towed to avoid the wheel making contact with the ground which may cause damage to the wheel, caravan or towing vehicle.
The jockey wheel is lowered or re-attached when the caravan is unhitched so that the jockey wheel makes contact with the ground. This provides support for the front of the caravan to keep the floor of the caravan level and the wheel facilitates manoeuvring of the caravan once it is unhitched.
With conventional jockey wheels, moving the caravan once it has been unhitched involves manual pushing or pulling of the caravan. it is known to provide a jockey wheel in which the jockey wheel can be manually driven using a rotatable handle near a top of the body member. This allows the wheel to be driven by rotating the handle which facilitates moving the caravan. However, such manually driven jockey wheels may be difficult for a user to operate if, for example, the user is elderly or disabled. Such manually driven jockey wheels may be unsuitable for providing a permanent replacement for a conventional jockey wheel. It has also been noted that such manually driven jockey wheels may be of such a size that, while installed on the towing hitch, they can prevent access to gas bottle lockers which may be locked near the towing hitch of the caravan or they can prevent the tailgate of a towing vehicle from being opened.
It is also known to provide a motorised mover device which can replace a conventional jockey wheel to facilitate the moving of a caravan. However, current motorised devices suffer some of the size disadvantages of the manually driven jockey wheels mentioned above and must be removed and replaced by a conventional jockey wheel before towing of the caravan. Motorised mover devices are also typically heavy and so are difficult to move around. Motorjsed mover devices are typically unsuitable for fitting to a bracket on the inside of a towing hitch and must be fitted to the outside which increases the overall size of the caravan assembly.
It is an object of the present invention to provide a more convenient jockey wheel assembly.
According to the invention there is provided jockey wheel assembly for a caravan, the jockey wheel assembly comprising a body and a bottom drive portion, the body being elongate along a first axis and the bottom drive portion being attached to an end of the body, the bottom drive portion comprising at least one wheel, the wheel being rotatably mounted to the bottom drive portion, the bottom drive portion further comprising drive means for driving the wheel, the drive means comprising a motor means coupled to the at least one wheel such that the motor means can be activated to cause rotation of the at least one wheel, the bottom drive portion being manually removable from the body by a user and the jockey wheel assembly including switch means for activating the drive means.
The term manually removable by a user is used herein to describe that a user may remove and refit the relevant component by hand without the need for tools. This may be achieved in a number of ways, for example bayonet fittings, press fit couplings or other means may be used. However, it is presently preferred that, to allow the removal and refitting of the bottom drive portion, a region of the body or bottom drive portion includes an external thread and that the other of the body or removable portion includes a collar having an internal thread rotatably secured thereto such that the collar may engage with the external thread to secure the body to the bottom drive portion.
It should be understood that the term wheel used herein is used to include wheels that engage the ground using tyres or the like, and also to include wheels that form part of a track drive system which engages the ground.
Having a removable bottom drive portion allows the jockey wheel assembly to be quickly fitted to an existing bracket without the need to completely release the bracket or remove any cover or cowling covering the towing hitch. This is made possible because the bottom drive portion of a jockey wheel assembly is wider than the body member, so removing the bottom drive portion enables the body member to slide through the clamp before the bottom drive portion is reattached. By making the bottom drive portion, which includes the wheel, removable the need to remove the jockey wheel assembly, or raise the wheel for transportation of the caravan or trailer is reduced. Since the body does not include the drive means, the body can be smaller than would otherwise be possible and this enables the bottom drive portion to be replaced with a bottom manual portion to substantially replicate a standard jockey wheel, with the exception that the bottom manual portion is removable.
Providing a jockey wheel assembly with removable and replaceable portions means that in the event of damage to one or more of the parts of the jockey wheel assembly, the user is able to replace only the damaged part without the need to replace or service the entire assembly.
The body preferably includes a sleeve and an arm, the sleeve fitting over, and being movable relative to, the arm by rotation of a rotatable member which is preferably located in an end of the body opposite the end to which the bottom drive portion is attached. The jockey wheel assembly may be attached to the caravan towing hitch using a bracket that clamps onto the sleeve that surrounds the arm. The arm and sleeve are arranged such that rotation of the rotatable member causes the arm to extend from, or retract into, the sleeve such that the length of the body can be adjusted. The rotatable member may be driven by a motor housed in a top portion of the body. The rotatable member may also be manually rotated by a handle attached thereto. Such a handle may be removable.
The jockey wheel assembly may include a tiller that extends from the bottom portion. Preferably the tiller extends substantially parallel with the direction of travel of the at least one wheel. The tiller facilitates manual orientation of the wheel so that when the wheel is driven by the motor the caravan travels in the correct direction. If the tiller is aligned with the direction of travel of the wheel, then orientation of the wheel is facilitated. The tiller is preferably removable so that the assembly is less cumbersome when not in use as this makes storage easier and reduces the number of protrusions from the assembly that may cause injury.
It is preferred that the jockey wheel assembly comprises two wheels, one on either side of the bottom portion as this provides greater symmetry and may result in greater stability. it is preferred that both wheels can be driven by the motor means. The use of two wheels provides a greater area of contact with the ground and thus provides greater traction.
It should be understood that a jockey wheel assembly according to the invention may be suitable for use with any trailer and not just caravans, however for simplicity the invention will be described in relation to use with a caravan.
The drive means preferably includes a power source, for example a battery, which can be used to supply power to motor means. it should be understood that power for the motor means may be from an external source, for example a battery or generator in the caravan. If the drive means makes use of an external power supply then the drive means preferably includes a socket into which a power cable can be plugged for transferring power from the external source to the bottom drive portion. If the drive means includes a battery, it is preferred that the battery is rechargeable.
It should be understood that the drive means may include a fuel tank and the motor means comprise an internal combustion engine, the switch means may then actuate a clutch mechanism or increase engine speed to actuate a centrifugal clutch to In use, the switch means for activating the drive means may be located directly on the bottom drive portion, in physical contact with the bottom drive portion, for instance located on the tiller, body or at the end of a signal cable, or the switch means could be a remote switch means comprising, for example, a radio transmitter which a user can hold and a radio receiver forming part of the drive means. The switch means are preferably electronic, but may be mechanical or any other suitable switch means.
It is also preferred that the assembly includes a bearing to facilitate rotation of the bottom drive portion relative to the body. The bearing may be attached to the body or to the bottom portion, but is preferably attached to the body.
The invention also provides a jockey wheel kit for making a jockey wheel assembly for a caravan, the jockey wheel kit comprising a body, the body being elongate along a first axis, the kit further comprising at least a bottom drive portion and a bottom manual portion, each of which can be manually fitted, one at a time, to an end of the body by a user to create a jockey wheel assembly, the bottom drive portion comprising at least one wheel for engaging the ground, the wheel being rotatably mounted to the bottom drive portion, the bottom drive portion further comprising drive means for driving the wheel, the drive means comprising a motor means coupled to the at least one wheel such that the motor means can be activated to cause rotation of the at least one wheel, the bottom drive portion including switch means for activating the motor means, the bottom manual portion including a wheel for engaging the ground, a knuckle for attachment to the body and at least one trailing arm extending from the knuckle to a wheel end, the wheel being rotatably mounted at the wheel end of the at least one trailing arm, the bottom manual portion being arranged such that, in use, the at least one trailing arm extends from the knuckle transverse to the first axis such that the wheel automatically aligns itself with a direction of travel to facilitate manual movement of a caravan to which the jockey wheel assembly is attached.
Providing a kit including a single body, but interchangeable bottom portions enables a user to attach the body to the towing hitch of, for example, a caravan and to then swap between the possible bottom portions as required. For example, the majority of the time it may be desirable to fit the bottom manual portion as this facilitates manual movement of the caravan and is likely to be a low value part to replace in the event that it is damaged or stolen. The bottom drive portion can be fitted when the convenience of a driven wheel is required, but since it is likely to be of higher value than the bottom manual portion it may be desirable to remove the bottom drive portion when it is not in use so that it can be securely stored. The bottom drive portion can be replaced with the bottom manual portion as desired, or the body simply left without a bottom portion attached.
The kit may further include other items such as a tiller which is attachable to the bottom drive portion, a remote control handset or a bracket to secure the body to a towing hitch.
The body included with the kit preferably includes only a height adjustment, the body can therefore be physically small and light weight and hence remain attached to the towing hitch without substantially obstructing access to the towing vehicle or lockers on the caravan.
The invention also provides a jockey wheel assembly for a caravan, the jockey wheel assembly comprising a body and a bottom manual portion, the body being elongate along a first axis and the bottom manual portion being attached to an end of the body, the bottom manual portion including a wheel for engaging the ground, a knuckle for attachment to the body and at least one trailing arm extending from the knuckle to a wheel end, the wheel being rotatably mounted at the wheel end of the at least one trailing arm, the bottom manual portion being arranged such that, in use, the at least one trailing arm extends from the knuckle transverse to the first axis such that the wheel automatically aligns itself with a direction of travel to facilitate manual movement of a caravan to which the jockey wheel assembly is attached, the bottom manual portion being manually removable from the body by a user.
This jockey wheel assembly has the advantage that, by having a bottom manual portion that is removable from a body, swapping of bottom portions is made possible. Removal of the bottom manual portion can also facilitate storage and help to prevent damage to the bottom manual portion during transport, or while the caravan is on site.
The invention extends to the bottom drive portion and the bottom manual portion individually.
- 10 - The invention will now be further described, by way of example, with reference to the accompanying drawings, in which: Figures la and lb show views of a towing hitch of a caravan with a jockey wheel assembly attached; Figure 2 shows in more detail the jockey wheel assembly of Figure la; Figure 3 shows in more detail the jockey wheel assembly of Figure ib; Figure 4 shows the bottom portion of the assembly of Figure 2; and Figure 5 shows the bottom portion of the assembly of Figure 3.
Figure la shows a jockey wheel assembly 1 attached to the towing hitch 2 of a caravan (not shown) . The jockey wheel assembly 1 is attached to the towing hitch 2 using a clamp 6.
The jockey wheel assembly 1 comprises an elongate body 10 and a bottom drive portion 12. The top of the body member 10 includes a first rotatable member 14.
Figure lb shows a jockey wheel assembly 101 attached to the towing hitch 2 of a caravan. The jockey wheel assembly 101 comprises the same body 10 as the jockey wheel assembly 1 of Figure la. The jockey wheel assembly 101 includes a bottom manual portion 112.
- 11 - Figure 2 shows in more detail the jockey wheel assembly of Figure la. The body 10 is elongate and comprises a sleeve 16 and an arm 18. The sleeve 16 is located over the arm 18. The clamp 6 shown in Figure la is secured to the sleeve 16 and the arm 18 is movable relative to the sleeve 16 by rotation of the rotatable member 14 to allow the towing hitch 2 to be raised or lowered relative to the ground 20. The sleeve 16 is coupled to a threaded tube within the body 10. The threaded tube is coupled to the rotatable member 14 such that rotation of the rotatable member 14 causes rotation of the threaded tube and this in turn causes the sleeve 16 to move up or down relative to the arm 18 depending upon the direction of rotation of the rotatable member 14.
The bottom drive portion 12 includes two wheels 24 and drive means 23 comprising a motor means 22 coupled to two wheels 24 such that the motor means 22 can drive the wheels 24 to rotate. The wheels 24 engage the ground 20 and can therefore be used to drive the trailer to which the jockey wheel assembly 1 is attached.
The body 10 is coupled to the bottom portion 12 by a rotatable collar 26. The collar 26 is rotatably mounted on the arm 18 and includes an internal thread. The bottom portion 12 includes an external thread 38 with which the thread in the collar 26 engages to couple the bottom portion 12 to the body member 10.
The bottom drive portion 12 further comprises a tiller 32 that extends from a receiving portion 31 of the bottom drive portion 12 substantially parallel with the direction in which the wheels 24 would travel. The tiller 32 allows the bottom drive portion 12 to be rotated to control the direction in which the wheels 24 are facing and thus the direction of travel 32. The tiller 32 is manually removable from the receiving portion 31 for storage. The tiller 32 further includes switch means 33 on a handle 35. When the tiller 32 is located in the receiving portion 31 the switch means 33 can be used to activate the drive means 23. Activation of the drive means causes the motor means 22 to drive the wheels 24.
The bottom drive portion 12 is shown in greater detail in Figure 4 Figure 3 shows in more detail the jockey wheel assembly of Figure lb. The body 10 is the same as that shown in Figure 2. However, the jockey wheel assembly 101 includes a bottom manual portion 112 rather than a bottom drive portion 12.
The bottom manual portion includes a wheel 124 coupled to an axle 28 about which the wheel 124 is free to rotate. The axle 28 is coupled to a knuckle 29 of the bottom portion 112 by trailing arms 30 such that the bottom manual portion exhibits, in use, a castor action whereby the wheel 124 automatically rotates to face a direction of travel. The bottom manual portion 112 includes an external thread 138 that is manually engageable with the internal thread of the collar 26 mounted on the arm 18.
The bottom manual portion 112 is shown in greater detail in Figure 5 In use, the body 10 is fixed to towing hitch 2 by a bracket 6 and either the bottom drive portion 12 or the bottom manual - 13 - portion 112 is fixed to the body 10. To swap between the different bottom portions 12,112 attached to the body member the collar 26 is manually rotated until the internal thread disengages from the external thread 38, 138. The bottom portion 12,112 can then be removed and stored and replaced by the other. Fitting a bottom portion 12,112 is the reverse of removal, the collar 26 and external thread 38,138 are aligned and the collar 26 rotated to engage the internal thread and external thread 38,138.
When the bottom drive portion 12 is attached to the body 10 to form jockey wheel assembly 1 and the jockey wheel assembly 1 is secured to a towing hitch 2 of a caravan, a user can fit the tiller 32 into the receiving portion 31 and use the tiller to adjust the direction in which the wheels 24 are pointing. A user can then actuate the switch 33 to activate the drive means 23. Once activated, the drive means 23 uses the motor means 22 to drive the wheels 24 to move the caravan.
The present invention has been described above purely by way of example. it should be noted that modifications in detail may be made within the scope of the invention as defined in the claims.
