Description

2366545 PORTABLE ROTATING TYRE CUTTING & WHEEL BALANCING STAND This

invention relates to a Portable Rotating Tyre Cutting & Wheel Balancing Stand with transferable foot brake.

In the commercial transport industry i.e.: H.G.V. P.S.V. and tyre fitting industry weather standard tyre or super single there seems no other innovation of this type.

When cutting tyres without the use of the Portable Rotating Tyre Cutting & Wheel Balancing Stand the operative has to attempt to hold the tyre with one hand whilst cutting the tyre with his other hand. When the operative has cut as much of the tyre that he can reach in this position he has to try and turn the tyre by physically lifting the tyre off the ground to enable him to turn the tyre around. This process is continued until the tyre has been completely re-cut.

The objective of the invention is to simplify the process of tyre cutting.

The invention comprises of a horizontal stand with wheels located at the end of each stabilising arm. The wheels are situated in this position for maximum. manoeuvrability. The foot brake can be fitted to either side of the stand to enable right and ieft handed persons to use this invention.

To aid in the carriage and manoeuvre of the invention a handle is situated at the rear of the stand.

Situated at the top of the stand is the location point for the fitment of the slide way. This is secured in place by a locking pin.

The slide way comprises of an adjusting screw, which is connected to the carriage. At the top end of the adjusting screw a hexagon nut is fitted enabling the carriage to be lowered and raised. At the bottom end of the adjusting screw a locking nut is fitted to stop the carriage coming off.

Fitted to the front of the carriage is a flange with two location studs one at each end of the flange. The flange is mated up to the wheel rim by pushing the invention into position. The two location studs pass through the stud holes in the wheel rim. The wheel rim is locked in position by the hexagon nuts fitted to the location studs. The wheel is now in position for raising.

The invention has been designed to be collapsible for easy manoeuvrability and carriage. Also in this form the invention is easy to store.

The tyre cutter which can be easily bought ftom a too] company known in the industry to supply such tyre cutters. Whilst wheel I is off the ground you can balance by turning wheel 1, allowing to come to a stop on its own, then you mark with chalk or any form of marker, and repeat using balancing weights by adding to wheel and trying to get wheel to stop in different place each time the wheel I comes to rest. To dismantle after use the steps described above are carried out in the reverse of that sequence.

Claims

I - A Portable Rotating Tyre Cutting and Wheel Balancing Stand comprising the following. A base which incorporates small wheels which are mounted on the front of the stabilising arms, this allows the invention weather in the up position or in the down position and flat packed to be able to move from A to B. The flat packed position is primarily for transport in a van or car boot. The base also incorporates a foot brake which is used to slow or stop the tyre being re-cut from rotating. This brake can be mounted easily on either stabilising arm so to accommodate left and right handed people so encouraging a good working position. This is achieved by a single wing nut which retains the foot brake this allows easy change over from left to right or vice versa the wing nut fits onto the pivot shaft on the brake. The base also incorporates a handle which acts as a stabiliser at the rear of the invention when in the up position and being used. But in the down position becomes another lifting point handle.

2 A Portable Tyre Cutting and Wheel Balancing Stand as claimed in Claim I the base which mounts the slide way weather in the up position ready to work or in the down position. Flat packed, the slide way incorporates a handle at the top of the slide way which can be used to hang the tyre cutter on when not using the tyre cutter this handle also acts as a support when the slide way is in the down position.

3 A Portable Tyre Cutting and Wheel Balancing Stand as claimed in Claim I and Claim 2 the slide way also houses in the preferred set up an adjusting screw which can be single start or multi start thread, this though could be replaced with a hydraulic or pneumatic ram to lift and lower the carriage. The preferred set up with an adjusting screw is the most economical way to do this, The preferred method using an adjusting screw with either a single or multi start thread is attached to the carriage by sliding captured nut which follows the screw this nut in a preferred version would be of a material like alloys of Brass, Allimimium or copper or combination of them all. Plastic can also be used in this statement on page I of this document. The slide way as a retaining hole for a locking pin which fits from bottom of slide way and top of base.
