Abstract

A strap, for example for securing an accessory to a frame tube of a bicycle, comprises a band 2 of a resiliently extensible material which is provided with a buckle 8 . The buckle 8 has an opening 14 through which a tail end 6 of the band 2 can be passed. An outer bar 17 of the buckle 8 defines an edge of the opening 14 . A prong 18 is fixed to the outer bar 17 , and can be engaged with any one of a series of holes 10 in the band 2 when the band is flexed over the outer bar 17 and pulled taut. The prong 18 has a contact surface 26 which is profiled to define a notch 34, 38 which serves to inhibit accidental slippage of the band 2 from the prong 18.

Claims (33)

1 . A strap comprising a band of resiliently extensible material having:

a head end,

a tail end, and

at least one hole situated between the head end and the tail end,

the head end being provided with a buckle comprising a buckle body having upper and lower surfaces and a prong which is fixed to the buckle body and which projects outwardly of the buckle body in a direction away from the head end of the band, the buckle body also having a slot for receiving the tail end of the band, the slot being situated between the head end of the band and the prong, whereby the tail end of the band can pass through the slot and the band can be flexed to engage the prong in the hole to retain the band in a secured condition in the buckle, the prong having an upper surface which is non-convex and a lower surface which extends at an acute angle to a plane of the lower surface of the buckle body and faces in a direction away from the slot, the lower surface of the prong comprising a contact surface having a concave notch which receives an edge of the hole when the band is in the secured condition.

2 . A strap as claimed in claim 1 , in which the contact surface comprises a first flat section and an adjacent concave transition section which define the notch.

3 . A strap as claimed in claim 2 , in which the contact surface comprises a second flat section extending from the transition section in the direction away from the first flat section.

4 . A strap as claimed in claim 3 , in which the first and second flat sections are substantially parallel to each other.

5 . A strap as claimed in claim 3 , in which the first and second flat sections are inclined to each other at an angle of not less than 50° and not more than 65°.

6 . A strap as claimed in claim 2 , in which the first flat section is inclined to the plane of the buckle.

7 . A strap as claimed in claim 6 , in which the first flat section is inclined to the plane of the buckle by not less than 50° and not more than 65°.

8 . A strap as claimed in claim 1 , in which the buckle has first and second openings which are separated from each other by a bar, the second opening constituting the slot.

9 . A strap as claimed in claim 8 , in which the band has an enlarged head which is retained within the first opening to secure the band to the buckle.

10 . A strap as claimed in claim 1 , in which the outer bar has contact surfaces extending away from the prong and sloping downwardly in the direction away from the prong.

11 . A strap as claimed in claim 10 , in which the contact surfaces are inclined to each other by an angle of not less than 186° and not more than 210°.

12 . A strap as claimed in claim 1 , in which the hole is one of a plurality of holes distributed along the band, the holes being selectively engaged by the prong.

13 . A bicycle comprising:

a frame tube to which is secured a strap, the strap comprising:

a band of resiliently extensible material having:

a head end,

a tail end, and

at least one hole situated between the head end and the tail end,

the head end being provided with a buckle comprising a buckle body having upper and lower surfaces and a prong which is fixed to the buckle body and which projects outwardly of the buckle body in a direction away from the head end of the band, the buckle body also having a slot for receiving the tail end of the band, the slot being situated between the head end of the band and the prong, whereby the tail end of the band can pass through the slot and the band can be flexed to engage the prong in the hole to retain the band in a secured condition in the buckle, the prong having an upper surface which is non-convex and a lower surface which extends at an acute angle to a plane of the lower surface of the buckle body and faces in a direction away from the slot, the lower surface of the prong comprising a contact surface having a concave notch which receives an edge of the hole when the band is in the secured condition.

14 . A bicycle as claimed in claim 13 , in which an accessory is secured to the frame tube by the strap.

15 . A strap comprising a band of resiliently extensible material having:

a head end,

a tail end, and

at least one hole situated between the head end and the tail end,

the head end being provided with a buckle comprising a buckle body having upper and lower surfaces and a prong which is fixed to the buckle body and which projects outwardly of the buckle body in a direction away from the head end of the band, the buckle body also having a slot for receiving the tail end of the band, the slot being situated between the head end of the band and the prong, whereby the tail end of the band can pass through the slot and the band can be flexed to engage the prong in the hole to retain the band in a secured condition in the buckle, the prong having an upper surface which is non-convex and a lower surface which extends at an acute angle to a plane of the lower surface of the buckle body and faces in a direction away from the slot, the lower surface of the prong comprising a contact surface having a concave notch which receives an edge of the hole when the band is in the secured condition, wherein the contact surface comprises a first flat section and an adjacent concave transition section which define the notch.

16 . A strap as claimed in claim 15 , in which the contact surface comprises a second flat section extending from the transition section in the direction away from the first flat section.

17 . A strap as claimed in claim 16 , in which the first and second flat sections are substantially parallel to each other.

18 . A strap as claimed in claim 16 , in which the first and second flat sections are inclined to each other at an angle of not less than 50° and not more than 65°.

19 . A strap as claimed in claim 15 , in which the first flat section is inclined to the plane of the buckle.
