Abstract

An apparatus 1 for securing a wheel 4 comprises a housing 2 and a ramp 3. The wheel 4 is guided into the apparatus between guide wall 5 of the ramp 3 and between pairs of wheel engaging pads 6a, 6b, and 6c, each of which is mounted on a spring loaded shaft 7a, 7b, 7c. The unlocked apparatus is activated to secure a wheel 4 when a predetermined pressure (i.e. of a motorcycle or scooter) is applied to a T piece 10. When a wheel 4 is introduced to the apparatus 1 and pushes down on the T piece 10, bell crank arms 9a and 9b pivot towards each other. Upon actuation of the lock mechanism, pins (Figure 5a, 27) are inserted into bores (Figure 5b, 28) of the bell crank arms 9a and 9b, locking them in position. This prevents the motorcycle from being removed from the apparatus and also prevents the pairs of wheel engaging pads 6a, 6b, 6c from being prised apart. The apparatus may form part of a parking system which may also include a controller such as a parking meter.

Description

24549Q 1 Apparatus for Securing a Wheel

Field of the Invention

The invention relates to an apparatus for securing a wheel; in particular an apparatus for securing the front or rear wheel of a motorcycle or scooter, for example when a motorcycle or scooter is parked.

Background of the invention

Motorcycles, scooters and bicycles are often targets for thieves. Wheel locks, chains and similar security devices often prove ineffective. Thieves sometimes remove one or more of the wheels or lift the entire motorcycle or bicycle into a van.

Motorcycles need to be stabilised in an upright position when being transported or when parked to protect them from damage.

A number of devices have been proposed to protect bicycles or motorcycles from damage by stabilising them in a upright position. There are also various stands which have been designed to prevent theft of motorcycles.

USS3OI 817 (Merritt) discloses a motorcycle security stand for locating the front wheel of a motorcycle. The stand includes side supports, each having three moveable U-shaped ribs, which can be moved to adjust the position of two arcuate flanges, which hold the wheel. Once in position, the apparatus is fixed using screws.

US5988402 Mayfield) discloses a motorcycle stand for a front or rear motorcycle re. When the tyre enters the stand, it rotates a curved metal plate forward. This causes two capture plates, one on either side of the tvre, to be pivoted inwards to contact the n-re. US6755309 (Runge discloses a similar mechanism for a bicycle stand, having a ramp and three-way hinge. When a wheel is rolled onto the ramp, it presses down on the hinge causing support surfaces at either side of the wheel to move towards each other to enclose, capture or support the wheel.

US573541 (I (Kallstrom) describes a motorcycle stand for supporting and locking a motorcycle at its front wheel. The weight of the front wheel acts on a pivotal ramp, which activates front tyre-engaging supports and rear lyre-engaging supports. The front lyre-engaging supports comprise arms with pads at the ends, which close against O( )sing sides of the t-vre. The rear tvrc-engaging supports include clamps or jaws, which engage the tue at a point below the location of the front fl-re-engaging supports. A locking mechanism locks the supports in position.

EP1086887 (Russi) and US5901725 (libby) both describe stands combined with shelters EPI 1)86887 (Russi) describes a parking shelter for scooters and other two-wheeled vehides, which is associated with the support for the scooter/vehicle can lock in variable positions. US5901725 (Libby) describes a bicycle shelter and stand with a weather shield protecting the front wheel of a bicycle.

The prior art devices do not hold a wheel securely in an upright position and are not suitable for use with a range of different vehicles because they do not adjust to accommodate different sizes of wheels.

It would therefore be desirable to provide an improved apparatus for securing a wheel.

Summary of the Invention

One aspect of the invention provides an apparatus for securing a wheel as specified in Claim 1.

A further aspect of the invention provides a parking system as specified in Claim 22 Preferred aspects of the invention are specified in the claims dependent on Claims I and 22 and

Detailed Description of the Preferred Embodiments

As shown in Figures 1 and 2, an apparatus for securing a wheel 1 comprises a housing 2 and a ramp 3.

The housing 2 includes a hood 2a, which protects the front of the motorcycle and prevents access to the wheel of the motorcycle, making it difficult for thieves to remove the wheel or lift the motorcycle out of the apparatus 1.

A solar panel 11 is located in the housing. The solar panel charges a battery, which is used to lock the apparatus 1.

Preferably the housing 2 is made from manganese steel and includes strengthening ribs 8 as shown in Figure 3.

As shown in Figure 4, a wheel 4 is guided into the apparatus I between guide walls 5 of the ramp 3 and between wheel engaging pads 6a, 6b and 6c, each of which is mounted on a spring loaded shaft 7a, 7b, 7c.

The wheel engaging pads 6a, ób, Sc are arranged in pairs on either side of the ramp 3. The wheel engaging pads 6a, 6b, 6c are shaped to optimise the path of a wheel into the apparatus. In particular, the surfaces 6a' are angled at approximately 45 degrees to the central axis of the apparatus and 45 degrees to the horizontal axis of the apparatus 1.

The apparatus I is shown in Figures 1 and 2 in an unlocked configuration. The unlocked apparatus is activated to secure a wheel 4 when a predetermined pressure is applied to a T piece 10 when the wheel of the motorcycle or scooter being rolled onto the T piece 10.

The motorcycle or scooter may be driven into the apparatus I so that the combined weight of the motorcycle and a rider pushes down the T piece 10.

Referring to Figures 4, 5a and 5b, as a wheel 4 rolls onto the T piece 10 is pushed down, which in turn pushes down on the lower portions 9a' and 9b' of bell crank arms 9a and 9b causing opposing bell crank arms 9a and 9b to pivot about pivot points 12 and 13 towards each other. At pivot points 13 the bell crank arms 9a, 9b are pivotally attached to a support 14.

Each bell crank arm 9a, 9b includes a cable mount 15, on which cables 16 are mounted. When the bell crank arms 9a, 9b pivot towards each other, the cable mounts 15 pull opposing cables 16 through cable plates 17, towards each other.

As shown in Figures 5a and Sb, the bell crank arms 9a, 9b include a locking mechanism, which comprises a solenoid 26 and a locking pin 27. When a wheel 4 is introduced to the apparatus I and pushes down on the T piece 10, bell crank arms 9a and 9b pivot towards each other. Upon actuation of the lock mechanism, pins 27 are inserted into bores 28 in the bell crank arms 9a and 9b.

This prevents further movement of the bell crank thus locking the bell crank arms 9a and 9b in a position such that there is a gap between them greater than or equal to the width of the widest spoke of the motorcycle. In a preferred embodiment, the bell crank arms 9a, 9b lock in a position between the wheel rim and underneath the brake disc apparatus of the motorcycle. This prevents the motorcycle from being removed from the apparatus and also prevents the pairs of wheel engaging pads 6a, ób, 6c from being prised apart.

One end of each cable 16 is attached to the cable mount IS. The other end of each cable is associated with one of the spring loaded shafts 7a, 7b or 7c.

Figures 6a and 6b illustrate the mechanism at shaft 7a. The shaft is moveablc in a shaft housing 19 and is biascd towards the central axis of the apparatus by a spring 18. A wheel 4 introduced into the apparatus 1, pushes against ihe wheel engaging pads óa, 6b, 6c. The associated shafts 7a, 7b, 7c slide within their shaft housing allowing the wheel engaging pads 6a, ób, 6c to move to their optimum positions for the width of the wheel 4.

A boss 2Ois attached to the end of the cable 16. The boss engages a locking plate 21, which has a toothed surface. When the apparatus I is in an unlocked configuration, the boss 20 and locking plate 21 are biased by a spring 23 such that the toothed surface of the locking plate 21 does not engage with the teeth 22 on the shaft 7a.

When the bell crank arms 9a, 9b close towards each other, the cable 16 is pulled against the spring 23 and the locking plate 21 drops onto the shaft 7a. The toothed surface of the locking plate engages teeth 22 on the shaft, preventing movement of the shaft and locking it in position.

The iocking plate 21 acts like a guillotine by dropping under gravity and by the extension of small springs 24, which arc able to expand when the spring 23 is recoiled.

When the apparatus 1 is unlocked by the solenoid 26, the apparatus remains in a closed position until a user begins to slide the wheel out of the apparatus I and weight is lifted from the T piece 10.

The bell crank arms 9a, 9b open and the cables 16 are no longer pulled against springs 23. The springs 23 expand, pushing the toothed surface of the locking plate 21 clear of the teeth 22, such that the shafts 7a, 7b, 7c can slide in the shaft housing and wheel engaging pads 6a, 6b, 6c can be moved apart. Expansion of the springs 23 also pulls cables 16, puffing the bell crank arms 9a, 9b open.

Thc same mechanism is uscd at each of the shafts 7a, 71) and 7c.

In an alternative embodiment as shown in Figure 7, levers 25 and rods 26 may be used to link the bell crank arms 9a, 9b to the shafts 7a, 7b, 7c. When the bell crank arms 9a, 9b move towards each other, rod 26' is pulled, causing rotating rod 27 to rotate. Rotation of the rotating rod 27 causes rods 26 to rotate the other levers 25. This in turn causes the flat face of each cam 28 to contact the face of a locking plate 29. This restricts movement of the shafts 7a, 7b, 7c against springs 30.

As illustrated in Figure 8, the apparatus may form part of a parking system 31 comprising more than one apparatus 1. The parking system may include a controller 32, such as a parking meter. The system 31 may include computer software. Alternativcly, a controller 32 may form part of the or each apparatus 1. Advantageously, the controller includes means to operate the locking mechanism.

The apparatus may be used to accommodate a front wheel or rear wheel of a motorcycle or scooter.

Tvrc widths of motorcycles vary from about 90mm to 120mm. Different sizes of wheel can be accommodated due to the adjustable positioning of the wheel engaging pads 6a, 6b, 6c.

Furthermore, correct positioning of the wheel engaging pads is automatic upon introducing a wheel to the apparatus 1.

Different numbers of wheel engaging pads and shafts may be used. In the preferred embodiments, a motorcycle engages all six wheel engaging pads 6a, 6b, 6c. However, a scooter may only engage pads óa and 6b.

The wheel engaging pads 6a, 6b, 6c and the bell crank arms 9a, 9b do not touch any part of the motorcycle body. Univ the tyres are touched by the wheel engaging pads 6a, 6b, 6c.
