Description

--
WHEEL ATTACHMENT ASSEMBLY
FIELD OF THE INVENTION
The present invention relates to a wheel attachment assembly that may be connected or retrofitted to an existing wheelbarrow or may form part of a wheelbarrow, and in particu'ar to an assembly which provides the wheelbarrow with two additional wheels for improved ease of use.
BACKGROUND TO THE INVENTION
Wheelbarrows are useful tools which allow a user to transport a range of objects or materials from one location to another. For example, a bricklayer may load and transport a wheelbarrow with bricks or rubble across a building site. In a typical domestic scenario, wheelbarrows are often used by gardeners for the collection and transfer of debris, e.g. as a means to transport fallen leaves to a rubbish bin or compost site.
WheethalTows work on the princip'e of having a collection area mounted on a frame, typically having a pair of handles at one end of the frame and a single wheel located at an opposite end to the handles. The frame additionally comprises a pair of braces, or legs, which act in conjunction with the wheel to support the wheelbarrow in an at rest position. The wheel acts as a fulcrum, or pivot point, such that a user is able to lift the braces of the wheelbarrow off the ground so that it can be moved from one location to another. When the wheelbarrow is loaded with items to be transported, particularly heavy ones, the nd result is Ihat more efforthas Lobe puL mb a) lilbing Llie wheelbarrow frame off the ground. and b) moving the wheelbalTow to a new position. This increased effort can be challenging for users, and also provides difficulties when having to manoeuvre bulky, heavy loads that are essentially balanced on a single wheel.
It would therefore be advantageous to have a wheelbarrow that reduced the effort required from a user to move bulky andlor heavy loads from one location to another. It
I
would be further advantageous if the wheelbarrow provided means for increasing the stability of the wheelbarrow in use. It would be highly advantageous if such means could be attached to a number of differently sized or shaped wheelbarrows available for sale or hire, or if the means could be sold as a separate kit of parts and be retrofitted to an existing wheelbarrow.
SUMMARY OF THE INVENTION
Accordingly, the present invention provides a wheel attachment assembly connectable to a first brace of a whedbarrow, the assembly comprising a pair of wheels mounted on an axle, the axle having a first elongate slot, and a first connection means passing through the first elongate slot for attaching the axle to the first brace.
The assembly will elevate the handles of the wheelbarrow, typically so that they adopt the position they would normally adopt when the handles of the conventional wheelbarrow are lifted by the user to a convenient height. When the handles are in this elevated position the three wheels of the wheelbarrow (i.e. the existing wheel at the front of the wheelbarrow, and the two wheels of the assembly) are in contact with the ground and provide improved stability. The user of the three-wheeled wheelbarrow does not have to lift the handles, as they are already elevated to a convenient working height, so the user can instead just push the wheelbarrow along the ground.
The assembly may be provided in a kit form that can be connected or retrofitted to an existing wheelbarrow. In this case, any openings or holes in the wheelbarrow braces that are necessary to connect the assembly to the existing wheelbarrow will be made by Ihe user. Mternatively, Ihe assembly can be connecLed to a wheelbarrow as pan oF the wheelbarrow manufacturing process such that it is an integral part of the wheelbarrow.
The assembly may be easily removed from the wheelbarrow if necessary by releasing the connection means.
The axle is preferably formed from a rigid material (e.g. metal) and typically has a tubular cross-section. The wheels are preferably mounted at opposite ends of the axle to give the three-wheeled wheelbarrow better stability. However, a skilled person will appreciate that the wheels may be mounted at alternative positions along the length of the axle as necessary. The diameter of the wheels can be chosen so that the handles of the wheelbarrow adopt a desired elevated position after the assembly has been connected, i.e. the handles are at a height that is comfortable for an average user.
The ax'e comprises a first elongate slot which allows a first connection means to pass through the slot in order to attach the axle to the first brace of the wheelbarrow. The first elongate slot preferably extends along the length of the axle in order to align with the respective brace of the wheelbarrow. In practice, the assembly will normally include a second connection means in order to attach the axle to a second brace of the wheelbarrow. The second connection means can pass through the first elongate slot (i.e. both connection means pass through the same slot in the axle) or through a second elongate slot. A skilled person will appreciate that an elongate slot provides a range of insertion positions to ensure that the first and second connection means can be connected to wheelbalTows with different brace spacings. This is particularly important when the assembly is to be connected or retrofitted to an existing wheelbarrow because it means that the axle can be properly connected to many different makes and models.
In an embodiment of the invention where the first elongate slot is anticipated to be a slot extending along a substantial length of the body of the axle, the assembly preferably further comprises a second connection means passing through the first elongate slot for attaching the axle to a second brace of the wheelbarrow.
In an alternative embodiment of the invention, the axle has a second elongate slot and Ihe assembly preleraNy further comprises a second connection means passing through the second elongate s'ot for attaching the axle to a second brace of the wheelbarrow.
The first and second elongate slots are preferably located adjacent the respective ends of the axle, although the skilled person will appreciate that they could be located at other positions along the length of the axle as required in order for the ax'e to be connected to wheelbarrows with different brace spacings.
Preferably, each connection means further comprises a bolt secured by a nut. The bolt can include a head and a threaded part for receiving the nut.
Each connection means preferaNy further comprises a spacer element located on the bolt (i.e. the spacer element includes an opening that is sized to receive the bolt) between the respective brace and one of the boll head and the nut. The spacer element may be sized and shaped to conform to a tubular (or other) brace cross-section.
Each connection means also preferably further comprises a spacer element located on the bolt between the axle and the other of the bolt head and the nut. The spacer element may be sized and shaped to conform to a tubular axle cross-section. It will be clear that each connection means may include two spacer elements, a brace-side spacer element which is typically in contact with the respective wheelbalTow brace and an axle-side spacer element which is typically in contact with the axle.
Each spacer element may be formed from a suitable plastics material. Each spacer element preferably has a substantially flat surface (typically opposite the surface that is shaped to conform to the axle or respective brace) in order to provide a suitaNe surface against which the bolt head or the nut, or an interposed washer, can bear when the connection means is tightened to fixedly connect the axle to the respective brace.
Each connection means also preferably comprises a washer located on the bolt between the brace-side spacer element and the bolt head or nut and/or a washer located on the bolt between the axle-side spacer element and the bolt head or nut.
In an embodiment of the invenlion. each connection means may comprise the following components in this order: bolt head, first washer, first spacer element, second spacer element, second washer, and nut. The bolt head of each connection means can be located at either the brace or axle side as necessary.
The wheels are preferably mounted at opposite ends of the ax'e, and each wheel is preferably mounted by a wheel retaining means that is attached to the respective end of the axle. The skilled person will appreciate that the wheels could also be mounted at alternative positions along the axle as necessary.
Each wheel retaining means preferably comprises a hub that is inserted onto the respective end of the axle. The hub is preferably formed from a ngid material (e.g. metal) and may comprise a wheel retaining portion (typicafly a flange) and a securing portion which permits the hub to be attached to the axle, the hub preferaNy being secured by a split pin which is inserted through aligned openings in the securing portion and the axle. Each wheel is then retained in position on the axle between the corresponding hub and a washer. Each washeris secured by a spht pin which is inserted through an opening in the axle. Other forms of connection means may also be used, such as e.g. a standard threaded bolt and nut.
The present invention further provides a kit of parts that can be assembled together to form a wheel attachment assembly for connection to the braces of a wheelbarrow in use, the kit of parts comprising: an axle; a pair of wheels mountable on the axle; and first and second connection means, each connection means comprising: a bolt, a nut, and at least one spacer element adapted to be locatable on the bolt, wherein each connection means is adapted to be passed through an elongate slot in the axle for attaching the axle to a respective brace of the wheelbarrow.
Each connection means preferably further comprises a pair of spacer dements adapted to be locatable on the bolt. Each spacer element is preferably sized and shaped to conform to a tubular axle or brace cross-section.
Each connection means preferably Further comprises at eas one washer adapled In be locatable on the bolt.
The kit of parts preferably further comprises a wheel retaining means connectable to the axle.
Further features of the parts are generally as described above.
In use, the wheel attachment assembly can be connected to a wheelbaiTow by securing the axle of the wheel attachment assembly to the respective braces of the wheelbarrow using the first and second connection means. In particular. the threaded end of each bolt can be passed through a brace-side washer, a brace-side spacer element, an opening in the brace (which can be a pre-formed hole or which can be formed by a user, e.g. a clearance hole can be drilled through the lowest part of each brace), the elongate slot in the axle, an axle-side spacer element, and an axle-side washer, before the nut is inserted onto the threaded end and tightened to clamp the brace and the axle together.
Alternatively, the threaded end of each bolt can be passed through an ax'e-side washer, an axle-side spacer element, the elongate slot in the axle, an opening in the brace, a brace-side spacer element, and a brace-side washer, before the nut is inserted onto the threaded end and tightened to clamp the brace and the axle together.
