This invention relates to a cargo pack for attachment to a bicycle.
Bikepacking is a popular leisure pursuit which often involves multi-day touring on a bicycle, often an off-road bicycle such as a mountain bike. Everything needed for touring is carried on the bicycle or by the rider. There is therefore a need for luggage containers, often referred to as cargo packs, which can be attached to the bicycle and can be loaded with equipment such as clothing, sleeping bags and food.
“Soft” packs, such as collapsible bags, are known for this purpose, but pose particular problems. There is a temptation to overstuff such bags, which leads to them bulging beyond their normal dimensions which can cause them to come into contact with moving parts of the bicycle or of the rider. In particular, soft packs attached to frame tubes of the bicycle can project into the path of the rider's legs, and this can be a source of irritation and can even lead to abrasion of the rider's clothing or skin.
According to an aspect there is provided a cargo pack for attachment to a bicycle, the pack comprising: an outer casing of a flexible material. The outer casing has: an opening for loading the pack, oppositely disposed side walls, an attachment wall extending between the side walls and intended to lie adjacent a frame member of the bicycle, and elongate internal stiffening elements fitted to each side wall and to the attachment wall.
The pack may be elongate. The stiffening elements may extend in the lengthwise direction of the pack. The pack may have a generally rectangular cross-section. The outer casing may further comprise a fourth wall disposed opposite the attachment wall. The outer casing may further comprise oppositely disposed end walls closing opposite ends of the pack. At least one of the end walls may be provided with an aperture for the passage of a flexible supply element. The aperture may be provided with a closure. The outer casing may have an internal elongate pocket extending in the lengthwise direction of the pack. The stiffening element may be accommodated in the pocket. The elongate pocket may be provided on at least one wall of the outer casing selected from the side walls and the attachment wall. The pocket may be open at its end adjacent the end wall having the aperture. The respective stiffening element may be passed through the aperture for insertion into the pocket.
The pack may be provided with an additional stiffener in the form of a panel of stiff material extending over the inner surface of at least one of the walls of the outer casing. The pack may have a generally rectangular cross-section. The outer casing may further comprise: a fourth wall disposed opposite the attachment wall, and oppositely disposed end walls closing opposite ends of the pack. The additional stiffener may extend over the inner surfaces of the attachment wall, the fourth wall, and each end wall. The additional stiffener may extend over the inner surface of the attachment wall. The stiffening element fitted to the attachment wall may be secured to the additional stiffener. The attachment wall may be provided with a mounting block for securing the cargo pack to the bicycle. The stiffening element fitted to the attachment wall may be secured to the mounting block. The pack may be provided with an additional stiffener in the form of a panel of stiff material extending over the inner surface of at least one of the walls of the outer casing. The mounting block may be welded to the material of the attachment wall and extend through an opening in the additional stiffener. The mounting block may be secured within the opening by means of a clip which engages the mounting block on the side of the additional stiffener away from the material of the attachment wall. The mounting block may be provided with parallel grooves engaged by complementary parallel rails of the clip. The mounting block may be provided with a recess accommodating an end of the stiffening element fitted to the attachment wall. The attachment wall may be provided with at least two of the mounting blocks. A respective one of the stiffening elements may extend between the or each two adjacent mounting blocks.
