Title: A device suitable for protecting and/or allowing cleaning of a bike and/or vehicle component and method of use thereof

Description:
This invention relates to a device suitable for protecting, allowing cleaning, servicing and/or lubrication of a bike and/or vehicle component, such as for example a brake and/or disc component of a bike, and a method of use thereof. 
     Although the following description refers almost exclusively to a brake and/or disc protection device for use on the rear wheel of a bicycle, it will be appreciated by persons skilled in the art that the device of the present invention could be used on any type of wheeled vehicle, such as for use on a motorbike, tricycle and/or the like, for shielding, protecting, allowing cleaning, servicing and/or lubrication of any or any combination of components of a bike or vehicle. The device of the present invention can be used to shield a part or whole of the locality in which the bike or vehicle is located in use. The device of the present invention can also be used to isolate or separate one or more components, such as for example the brake and/or disc, from one or more other components, such as for example the gear cassette, rear derailleur, chain and/or the like. 
     It is known to provide a brake and/or disc protector for location over a brake and/or disc of a bicycle or a motor bike during cleaning processes, lubricating processes and/or the like. 
     The protector typically prevents any cleaning fluid or lubricant from coming into contact with the brake and/or disc of the bike during the cleaning and/or lubricating process, which might significantly reduce the braking performance of the brake and/or disc in use. 
     GB2477726 discloses a brake shield comprising two circular flexible and waterproof members which are joined together by stitching. Each member has a radial slit to allow the same to be located around the brake disc. The two members overlap to cover the brake disc. A problem with this product is that any cleaning fluid or lubricator impacting with the circular member eventually drips down to the base edge of the member and onto the floor on which the bike is being cleaned. This creates a mess in the area of where the bike is being cleaned, which is undesirable and which might result in a slipping hazard to animals or people. A user therefore typically has to clean/lubricate the bike and then clean the surrounding locality of the cleaning/lubrication fluid afterwards. This is time consuming for the user and it may be difficult to remove all trace of the spilt/dripped cleaning/lubricating fluid from floor surfaces on which the bike was cleaned. 
     In an attempt to overcome this problem it is known to provide a motor bike brake shield with an integral and rigid sump. The sump collects run off of any cleaning/lubricating fluid used on the motor bike during maintenance. A pouring spout can be provided on the sump to allow the collected fluid to be decanted into a container for safe disposal. This shield is typically relatively expensive to produce, large and difficult to transport. This is particularly a problem where the bike may need to be maintained or serviced away from the user&#39;s home or normal base, such as when the user is travelling, on holiday, at races and/or the like. 
     GB2417935 discloses a removable cleaning shield comprising a disc formed from moulded plastic. The disc has a trough which collects excess cleaning and lubrication fluid. A central hinge allows the shield to be folded in half for storage and a hole is provided to allow it to be hung up. However, due to the presence of the fixed trough, the shield cannot be folded flat and therefore is still relatively large and cumbersome to transport and store. 
     It is therefore an aim of the present invention to provide a device suitable for protecting, allowing cleaning, servicing and/or lubrication of one or more components of a vehicle and/or bike that overcomes the abovementioned problems. 
     It is a further aim of the present invention to provide a method of using a device for protecting, allowing cleaning, servicing and/or lubrication of a bike and/or vehicle component that overcomes the abovementioned problems. 
     It is a yet further aim of the present invention to provide a brake and/or disc isolation, protection and/or separation device for isolating, protecting and/or separating the brake and/or disc from one or more other components on a bike or vehicle. 
     It is a yet further aim of the present invention to provide a method of using a brake and/or disc isolation, protection and/or separation device. 
     According to a first aspect of the present invention there is provided a device for protecting, allowing cleaning, servicing and/or lubrication of one or more components of a bike and/or vehicle in use, said device formed from at least one blank of material including a first portion arranged to act as a shield element so as to at least partially shield at least one component of the vehicle or bike in use, and at least a second portion, said second portion including at least one wall joined to the first portion by at least one fold line, the at least one wall and fold line arranged such that when the second portion is assembled and/or erected in use it defines a tray or container portion joined to the first portion. 
     In one embodiment the device is a brake and/or disc protection device. The first portion is arranged to act as a shield element so as to at least partially shield the brake and/or disc of a vehicle or bike in use. 
     Thus, the present invention provides a device having a foldable tray or container portion, thereby allowing run off of fluid, dirt and/or debris to be collected during cleaning, servicing and/or lubrication processes when the device is an assembled, erect and/or in-use condition, and which allows the device to be moved to or folded to a flat or substantially flat condition when in a disassembled, collapsed, partially collapsed and/or out-of-use condition. This increases the case with which the device can be transported and/or stored. It is therefore much easier for a bike rider, for example, to be able to transport the device to races, on holiday, to training venues and/or the like. The present invention can also be used to protect any or any combination of components of the bike or vehicle, such as for example, the bike tyres, the wheel rims and ultimately the callipers and braking power of wheel rim brakes. The protection of such features maintains the efficiency of the brakes and the stopping distance of the bike or vehicle. 
     It is to be noted that the device can be fully assembled (with the tray or container portion formed) but still foldable to a flat, planar or substantially flat or planar condition in use. 
     Preferably the at least one blank is movable from a disassembled, flat, planar, substantially flat or substantially planar condition to an assembled and/or erect condition in use. The at least one blank is movable between the two conditions by moving the first and/or second portions relative to each other and/or about the one or more fold lines. 
     The tray or container portion is not formed or assembled when the at least one blank is in the disassembled condition. 
     In use of the device in one embodiment, the device is fitted to a side of a bike wheel on which the gear cassette is fitted, and between the wheel and the gear cassette, rear derailleur and/or chain. The device therefore acts to isolate or separate the gear cassette, rear derailleur and/or chain from the brake and/or disc provided on the opposite side of the bike wheel. Thus, the device can be used to protect the brake and/or disc during cleaning, servicing and/or lubricating processes undertaken on the gear cassette, rear derailleur and/or chain. The device can also be used to isolate the brake and/or disc from the other bike components to allow the brake and/or disc to be cleaned and/or repaired. Thus, in one arrangement, the device of the present invention can act as a cleaning aid device, an isolation or separation device and/or a protection device and is not specifically limited to protecting just a brake and/or disc component(s) of the bike or vehicle but any component(s) of the bike or vehicle. 
     In use of the device in one embodiment, the device is fitted to a side of a bike wheel on which a brake disc is provided, and between the wheel and the brake disc. The wheel can be the front and/or rear wheel of the bike. The device can be used to collect any dirt and/or fluid associated with cleaning the brake discs. In this embodiment the device is also acting as a cleaning aid device. 
     Preferably the one or more components of the bike and/or vehicle which are to be protected, separated, cleaned, serviced and/or the like are any or any combination of a wheel, wheel rim, brake and/or disc, gear cassette, rear derailleur, chain, wheel axle, wheel spokes and/or the like. 
     Preferably the term “shield” also means to cover, hide, isolate, protect and/or the like. 
     Preferably the second portion comprises or consists of two or more walls, and further preferably a plurality of walls, separated by fold lines, the walls and fold lines are arranged such that when the second portion is assembled or erected in use, it provides a tray or container portion joined to, and preferably integral with, the first portion. 
     Preferably the second portion is moved from a disassembled, flat, planar, substantially flat or planar condition to an erect and/or assembled condition by moving one or more walls of the second portion about one or more fold lines relative to one or more other walls of the second portions and/or first portion to form the tray or container portion. 
     In one embodiment the second portion can form a tray or container portion on one side of the first portion only. Preferably the side on which the tray or container portion is formed protrudes outwardly of the bike or vehicle in use. 
     In an alternative embodiment the second portion can form a tray or container portion on either side of the first portion (i.e. the front or rear surface of the first portion), and/or both sides of the first portion (i.e. the front and rear surfaces of the first portion).

     Referring to  FIG. 1 , there is illustrated a brake and disc protection device  2  for use on a bicycle  4 . The device  2  includes a first portion  6  acting as a shield for the brake and disc of the bike and a second portion  8  acting as a tray to collect fluid run off, dirt and/or debris that may result from a cleaning and/or lubricating process undertaken on the chain and gear mechanism  10  of the bike. 
     The first portion  6  has a circular external shape and has engagement means in the form of a radial and linear slit  12  defined therein from the centre to a peripheral edge of the first portion to allow the first portion to be slotted onto the wheel axis between the gear mechanism/cassette  10  and the spokes  14  of the bike wheel  16 . The brake and disc are located on the opposite side of the wheel spokes  14 /wheel  16  to the gear mechanism  10  and are therefore shielded by first portion  6  when the device  2  is fitted to the bike. It will also be appreciated that as well as shielding, the device  2  can act as a separation or isolation member, so that the brake and disc are separated or isolated from the gear mechanism/cassette  10 , thereby allowing the brake and disc to be cleaned and/or repaired without effecting the gear mechanism/cassette  10 . 
     An aperture  18  is defined in first portion  6  for the location of an end of the rear bike wheel axle therethrough when the device is fitted to the bike. The aperture  18  is continuous with and in communication with the slit  12 . The end of the wheel axle is pushed through the slit until the end of the wheel axle sits in aperture  18  in use. 
     Attachment means for attaching the device to the bike are provided in the form of circumferential protrusions  20 ,  22 . The protrusions  20 ,  22  are provided a spaced distance apart adjoining a top edge  24  of the device  2 . A slit  26  is defined between each protrusion  20 ,  22  and the first portion  6  to allow the protrusion to be attached to the wheel spokes  14  in use. The circumferential protrusions are planar with the first portion  6  and protrude radially outwardly beyond the peripheral edge of the first portion. 
     The first portion  6  is typically of such dimensions so as to shield the part of the bike adjacent the tear derailleur  28 , the gear cassette  10  and at least the rear part of the drive chain  30 . 
     In accordance with one embodiment of the present invention, the device  2  is formed from a single blank of material  100 , as shown in  FIG. 2 . The device can be moved from the flat, planar blank condition of  FIG. 2  when not in use, to an assembled or erect in-use condition, as shown in  FIG. 1 . In the erect in-use condition, the tray of the second portion  8  protrudes outwardly from the planar surface of the first portion  6  of the device, as will be described in more detail below. 
     The device  2  is typically made from a relatively flexible sheet like material, such as relatively thin plastic sheet, that allows the device to be moved between flat, erect and/or folded conditions multiple times. 
     The first portion  6  is formed from a single wall element in this illustration, although it will be appreciated that the first portion could be formed from a plurality of wall elements separated by fold lines, such that the first portion can be folded to a compact size when not in use and moved to an extended flat, planar condition when in use. 
     Second portion  8  comprises a front wall  32  joined to first portion  6  along fold line  34 . Second portion side walls  36 ,  38  are joined to the side edges of front wall  32  along fold lines  40 ,  42  respectively. 
     First portion  6  also has fold lines  44 ,  46 , which are mirror images of fold lines  40 ,  42 . The fold lines  44 ,  46 ,  40 ,  42  adjoin fold line  34  at the same point, to define first portion side walls  48 ,  50 . First portion side walls  48 ,  50  are joined to second portion side walls  36 ,  38  along fold lines  52 ,  54  respectively. 
     During assembly, front wall  42  is moved towards first portion  6  by folding the front wall along fold line  34 . At the same time, side walls  48 ,  50 ,  36 ,  38  are moved inwardly of the device towards each other by folding the walls along fold lines  40 ,  42 ,  44 ,  46 ,  52 ,  54 . This forms a tray having a rear wall formed from the lower part of the first portion, a front wall  32 , side walls  48 ,  50 ,  36 ,  38  and an opening  55  defined between a top edge  56  of the second portion walls. This tray portion allows debris and run off fluid to flow down the front of the first portion, through the opening of the tray portion and be captured in the tray portion for later disposal. 
     The opening  55  of the tray is typically arranged so that a longitudinal axis of the tray is parallel or substantially parallel to the longitudinal axis of the bike. 
     Apertures  58  can be defined in front wall  32  and side walls  36 ,  38 ,  48 ,  50  to allow securing means in the form of ties  60  to be located through the same in use to secure the tray portion in the erect condition. 
     The blank can be moved between the erect/assembled condition and the flat blank condition as often as required. It will also be appreciated that the side walls of the tray portion are collapsible by way of moving the adjacent side wall portions  36 ,  48  or  38 , 50  towards each other even after the blank has been assembled. This allows the tray portion to be flattened. As such, the device can be moved to a flat or substantially flat condition even when the blank has been fully assembled to form the tray portion. 
     The device can be for a single use only and disposable thereafter or can be used multiple times as required. 
       FIG. 3  illustrates a further embodiment of a blank  102  that can be used to form a brake and disc protection device similar to that shown in  FIG. 1 . The same reference numerals have been used to describe the same features as in the abovementioned embodiment. 
     In the further embodiment shown in  FIGS. 3 and 4 , there are no attachment protrusions  20 ,  22  and the first portion simply locates around the rear axle of the bike via aperture  18 . The first and second portion side walls  36 ,  48  have been combined to form a single side wall  104  and side walls  38 ,  50  have been combined to form a single side wall  106 . The side walls  104 ,  106  are joined to first portion along fold lines  44 ,  46  respectively. The front wall  32  and side walls  104 ,  106  are of similar size and shape and the fold lines separating the same meet at a point  108 . During assembly, front wall  32  is moved towards first portion  6  and side walls  104 ,  106  are moved towards each other. An apex  110  formed between the outermost edge of front wall  32  and side wall  106  can be secured in a slit  112  defined in second wall  106  to secure the tray portion in the assembled position in use. 
     Referring to  FIGS. 5-8 , there is illustrated a further embodiment of a brake and disc protection device  202 . Whereas the devices  100 ,  102  described in  FIGS. 1-4  are formed from a single blank, the embodiment shown in  FIGS. 5-8  has two blanks that are pivotably movable relative to each other. This pivotal movement helps to engage the device  202  to the wheel of the bike in use. 
     Brake and disc protection device  202  comprises a first blank  204  and a second blank  206 . The second blank  206  is pivotable relative to the first blank  204  around pivot pin  208 . The pivot pin  208  passes through the first and second blanks. 
     First blank  204  comprises a first upper portion  210  and a second lower portion  212 . The first upper portion  210  has a circular section  210   a  with a rectangular section  210   b  below the circular section. An aperture  214  is defined in the first upper portion  210 , and preferably (but not necessarily essentially) in the circular section  210   a . This aperture  214  allows the device to be located around an end of the wheel axle of a bike as in the first embodiment. A wedge shaped slot  216  extends outwardly from the aperture  214  to aid fitting of the axle into aperture  214  in use. 
     Second blank  206  is approximately semicircular in shape in this example, but could be any required shape, providing the second blank  206  does not obstruct the aperture  214  or wedge shaped slot  216  in its disengaged position (as will be described in more detail below). Second blank  206  also has an aperture  218  for location around the end of the wheel axle of the bike in use and a slot  220  extending from the slot to a peripheral edge  222  of the blank. 
     Second blank  206  is movable from a disengaged position, as shown in  FIG. 5 , wherein second blank  206  is moved clear of aperture  214  and slot  216 , thereby allowing the first blank to be fitted to an end of a bike wheel axle as described above; to an engaged position, as shown in  FIG. 6 , wherein second blank  206  is moved to cover slot  216 . In the engaged position, aperture  218  of the second blank  206  is aligned with aperture  214  of the first blank so that part of the wheel axle of the bike can pass therethrough. 
     Although the second blank is typically retained in the engaged position by way of gravity, securing means can be provided to allow the first and second blanks to be further retained in the engaged position in use. 
     In the illustrated embodiment, the securing means are in the form of a flexible tab  224  provided on the second blank for location in securing means in the form of a slot  226  provided on the first blank when the first and second blanks are in the engaged position. The tab is simply flexed and inserted into slot  226 . The securing means are typically provided on the opposite side of the pivot pin  208  to the slot  220  and  216  of the second and first blanks respectively. The securing means are typically provided adjacent a peripheral edge of the blanks  204 ,  206 . 
     The second portion  212  is typically folded in a similar manner to that shown in the first embodiment to form a tray that protrudes outwardly from a front planar surface of the blanks  204 ,  206  and wheel  16 . In particular, second portion  212  has a front wall  232  and two side walls  234 ,  236  located either side of front wall  232  and joined to front wall  232  along fold line  233 ,  237  respectively. Second portion  212  is joined to first portion  210  along fold line  238 . The lower part  210   b  of first portion  210  has side walls  240 ,  242  joined along fold lines  241 ,  243  respectively. First portion side walls  240 ,  242  are joined to second portion side walls  234 ,  236  respectively along fold line  238 . 
     On assembly, the front wall  232  of second portion  212  is moved towards the front wall of first portion  210   b . The side walls  240 ,  242 ,  234 ,  236  are folded inwardly of each other along fold lines  241 ,  243 ,  233 ,  237 . Securing pins  228  are located through apertures  230  defined on the first and second portions to join the first portion to the second portion and to retain the tray in the erect condition in use. 
       FIGS. 9 a  and 9 b    show an example of a securing pin  228  and/or pivot pint  208  that can be used in the present invention in a separated, disengaged position, and an engaged position respectively. 
     The pin  228  includes a head portion  244  and a neck portion  246  extending outwardly from said head portion  244 . Head portion  244  has a larger cross sectional area than neck portion  246  and aperture  230 , such that with the neck portion  246  located through apertures  230 , the head portion  244  engages against the surface of the blank and prevents the head  244  and pin  228  from passing further through the aperture  230 . 
     The free end  248  of neck portion  246  has a slot  250  defined therein, the slot having a longitudinal axis that is parallel to the longitudinal axis of the neck portion  246 . The slot  250  provides the free end  248  with a degree of flex and/or a degree of resilient biasing force in an outwardly direction. An outwardly protruding lip or shoulder portion  249  is defined a spaced distance from free end  248  on neck portion  246 . A nut  252  is provided with an aperture  254  defined therein. The free end  248  of neck portion  246  is located through aperture  254  of nut  252  in use. A step (not shown) provided in the interior walls of nut  252  defining aperture  254  locates over the lip or shoulder portion  249  on neck portion  246  to engage the nut  252  in position on pin  228 . The outward resilient biasing force of the free end  248  moves the portions of the free end  248  outwardly of each other to retain the nut  252  in position on the neck portion  246 . 
       FIG. 10  shows an example of a brake and disc protection device fitted around the axle of a front wheel of a bike between the brake disc and the wheel.
