Description

Bicycle Wind Guard The present invention relates to a bicycle wind guard and, in particular but not exclusively, to a bicycle wind guard adapted to reduce the effect of adverse weather conditions on certain areas of the body during cycling.

Whilst cycling in cold weather conditions, the extremities of a cyclist, and in particular the hands, are exposed to the harsh elements. This can be extremely painful and can lead to the inability to hold the handlebars.

Furthermore, this problem can make operating the brakes and gears of the bicycle difficult and can put the cyclist in danger.

Products currently available to address this problem include thick gloves or mittens however these are often ineffective as they become saturated or allow the ingress of water (regardless of how waterproof the manufacturers say they are), and once the gloves have become waterlogged the additional wind-chill factor exacerbates any cold weather effects. Additional products that are available include chemically activated hand warmers which only offer transient warmth and are often bulky and difficult to insert into gloves.

In the Northern Hemisphere, in order to train for competitive races cyclists must expose themselves to the harsh elements during the winter months.

There is therefore a need for an improved product which can reduce the exposure of the extremities of a cyclist to harsh elements.

US4141567 discloses a rigid protective covering for the hands when operating a handle bar controlled vehicle that is attached securely to the vehicle and allows convenient access for an operator. The protective covering is in the form of a rigid plastic cover which is adapted to encircle the front 180 degrees of the hand of the operator of a handlebar-controlled vehicle. The covering is mounted securely by fastening devices to a handlebar mounted lever clamp just inboard of the operator's hand, and to an expanding fastener that is plugged directly into the end of the handlebar just outboard of the operator's hand. However, such a device is designed for conventional straight handlebar devices and is unsuitable for use with different handlebar configurations such as curved handlebars as found on racing bicycles. In addition, by encircling the first 180 degrees of an operator's hand, access to components of a bicycle that are not within the covering is restricted.

FR2821819 discloses a device for protecting the hands of a cyclist adapted to be fitted onto a racing bicycle. The device consists of a substantially flat windshield fixed to that brake lever of a racing bicycle by a flat rigid rod. The windshield is held flat against the lever by an elastic connection. While the device can be fitted onto a racing bicycle it only offers protection for a user when his hands are positioned on the drop down section of the handlebar behind the brake lever.

According to a first aspect, the present invention provides a bicycle wind guard comprising an outer shell having a first end and a second end wherein the first end comprises a cut-out portion adapted to receive a section of a handlebar therethrough and the second end comprises a sectional area adapted to engage with an outer profile of a handlebar.

The first aspect of the present invention is particularly adapted for use with the handlebars of a racing bicycle. The cut-out portion in the outer shell allows it to be easily fitted onto a curve handlebar. In addition, as a section of the handlebar can be received through the cut-out portion, the positioning of the wind guard can be adjusted for different length handlebars and to ensure it shields a user's hand from the elements when it is placed on the handlebar in his preferred riding position.

The present invention is also adapted to keep a cyclist's hands warm during the cold, wet and rainy season. It is especially helpful for people who experience longer training rides, in excess of 2 hours, where they will be exposed to the elements for a long time.
