External pocket for luggage pack

Abstract

A luggage pack in the form of a bar bag for attachment to a bicycle comprises an external stretch pocket made of a mesh with elastane or similar stretchy material, and a T-shaped Thermoplastic Polyurethane (TPU) component sewn into the leading edge of the pocket. The TPU component forms a strap, equipped with holes like a belt, for closure. A buckle is attached to the bag and supported by an internal structure of the bag. The strap is looped through the buckle and a prong on the buckle engages one of the strap's holes for secure closure. The design maintains bag stability, reduces flapping of the strap end, and provides easy, one-handed access to the bag.

DETAILED DESCRIPTION

(10) The present invention provides a uniquely designed bag closure mechanism primarily aimed at enhancing the functionality of bar bags attached to bicycles.

(11) The main component or body of the bag is made of a durable fabric. In one embodiment, the fabric is a Nylon variant with a Thermoplastic Polyurethane (TPU) coating that is welded together. The bag's distinctive feature is an external stretch pocket, in the form of a panel sewn or otherwise affixed to the main body. The stretch pocket can be made from any stretchy material. In one embodiment, the pocket panel is a mesh with elastane.

(12) A T-shaped TPU component is sewn into the leading edge of the stretch pocket. The TPU is selected for its resilient nature, with an elongation at break percentage in the hundreds, making it stretchy or elastic. The TPU strap extends outward from the pocket and is designed with a series of holes akin to a belt, enabling it to be used for closure. The T-shaped TPU component includes a slot in the union of the T, designed to receive the loose end of the strap, thereby reducing flapping of the strap end.

(13) In one unique feature of the invention, the T-shaped TPU component includes a groove running lengthwise along the top of the T. This groove captures the edge of the pocket on both sides before being sewn in, acting like a gripper. This design provides a more robust connection between the stretch pocket and the TPU component.

(14) A buckle, made from a material such as Nylon or Aluminum alloy, is attached to the top of the bag. It is secured to an internal structure within the bag, preferably made from Aluminum alloy 6061-T6 or a similar material. The attachment to the internal structure is facilitated by a screw that passes through a hole in the buckle, sandwiching the bag skin between the buckle and the internal structure, creating a watertight seal. This internal structure provides support to the buckle, enhancing the stability of the bag.

(15) The buckle is designed with a prong protruding from its top. The TPU strap loops around the buckle in a U-turn fashion, and the prong on the buckle engages with the holes in the strap. The engagement of the prong with the strap's holes secures the closure of the stretch pocket.

(16) In summary, this invention provides a bag with an enhanced closure mechanism for its stretch pocket. The design not only improves bag stability but also reduces flapping of the strap end and provides easy, one-handed access to the bag. The invention represents a significant functional improvement over previous bag designs and offers durability for prolonged use.

(17) FIG. 4 shows handlebars 2 of a bicycle, to which a luggage pack or bag 4 is mounted by a mechanism 6. Any suitable mechanism may be employed, but one possibility is that disclosed in our co-pending patent application GB2211838.4, to which reference is directed. The mechanism 6 provides easy adjustment of the position of the bag 4 relative to the handlebars 2, simple attachment and release of the bag 4.

(18) The bag 4 comprises a bag body 8 made from a flexible sheet material which may be a durable fabric. On the side of the body 8 directed away from the handlebars 2 there is a pocket 10 formed from a panel 12 of a stretchable material such as an elastane-containing mesh fabric. The panel 12 is secured along three edges, namely the lower edge, and each side edge, to the material of the body 8, for example by stitching, bonding or welding. The remaining edge 14, which is the upper edge as shown in FIG. 4, is free of the material of the body 8, and so provides an opening 16 giving access to the interior of the pocket 10.

(19) In the condition shown in FIG. 4, the pocket 10 is closed by means of a strap 18 and a buckle 20. The buckle 20 is secured to the body 8 of the bag 4, while the strap 18 is secured to the upper edge 14 of the panel 12 at a reinforcement portion 22. The strap 18 and the reinforcement portion 22 are formed integrally with each other from a resiliently stretchable material, such as thermoplastic polyurethane (TPU).

(20) The free edge 14 is formed by folding over and stitching the raw edge of the panel 12 to form a hem, and the reinforcement portion 22 is formed with a groove 23 in its lower edge (as viewed in FIG. 4) which receives the hem. The hem is secured to the free edge 14 by any suitable means, such as stitching, bonding or welding. The reinforcement portion 22 thus spreads any load applied through the strap 18 along a portion of the overall length of the free edge 14. It will be appreciated that the reinforcement portion 22 is elongate and extends in the lengthwise direction of the free edge 14.

(21) As shown more clearly in FIG. 3, the strap 18/reinforcement portion 22 unit is generally T-shaped. The strap is provided with a series of holes 24.

(22) FIG. 7 shows the pocket 10 in the open condition so that the access opening 16 is widely open to enable items to be placed into, or taken out of, the pocket 10. The strap 18 hangs downwardly. FIG. 7 shows, in dashed outline, a stiffening component 26 situated within the body 8 to give it a defined form, even when empty. An example of a suitable stiffening component 26 is shown in FIG. 1 and may, for example, be made from a suitably rigid plastics material such as nylon, or from a metallic material such as an aluminium alloy. The buckle 20 is secured to the body 8 by a fastener, such as a screw extending through a hole 27, which engages the stiffening component 26 to ensure a reliable connection.

(23) As shown in FIG. 3, the buckle 20 is provided with an aperture 28 and a fixed prong 30. As shown in FIG. 5, the strap 18 can be passed through the aperture 28 and drawn upwardly (as viewed in FIG. 5) to draw the panel 12 into the closed condition, reducing the size of the access opening 16. During this process, the strap 18 is placed under tension, and so stretches somewhat. When the pocket 10 is closed as far as possible (allowing for the bulk of any contents), the strap 18 can be folded back down towards the reinforcing portion 22, as shown in FIG. 8, and, with the strap 18 still under tension, the prong 30 can be engaged with an appropriate one of the holes 24. This retains the strap 18 locked against the buckle 22, to hold any contents in place, and to keep the access opening 16 closed as far as possible.

(24) FIG. 3 shows a slot 32 situated generally at the junction between the strap 18 and the reinforcing portion 22. As shown in FIG. 4, the free end of the strap 18 can be directed into the slot 32 to be accommodated behind the panel 12, i.e. within the interior of the pocket 10. This avoids unsightly projection of the free end of the strap 18 from the bag, and avoids catching of the strap 18 on any external objects.

(25) FIG. 6 shows the pocket 10 accommodating an article of clothing 34, such as a jacket. The bulk of the jacket 34 prevents the pocket 10 from being fully closed, but nevertheless the strap 18 can engage the buckle 20 by passing through the slot 32. The strap 18 can then be turned back and engaged with the prong 30 in an appropriate one of the holes 24. In this condition, the strap 18 is maintained under tension, to keep the pocket 10 secure and with the jacket 34 compressed to some extent.
