Abstract
A fastener (1) has an elongate fastening band (2) and a buckle (10) for engagement with the band (2) to form a closed loop fastener. The buckle (10) is overmoulded on a first end region (8) of the fastening band (2). Such a design provides a fastener that has higher strength and is more compact than previously-considered designs.
Claims10
A fastener comprising:
- an elongate extruded fibre-reinforced fastening band having a longitudinal axis and first and second planar surfaces, the longitudinal axis defining a longitudinal axis of the fastener, the first surface defining a plurality of teeth arranged substantially perpendicular to the longitudinal axis, and the second surface providing an engagement surface for the fastener, wherein the elongate extruded fibre-reinforced fastening band has a first end region, and a locking portion which is spaced apart longitudinally from the first end region, the first end region and locking portion defining respective groups of such teeth on the first surfaces thereof;
- and
- an injection-moulded buckle over-moulded onto the first end region of the fastening band and fused with the teeth of the first end region of the elongate extruded fibre-reinforced fastening band, the buckle and elongate extruded fibre-reinforced fastening band being arrangeable to form a closed fastener configured to compress or clamp at least one article encircled by the elongate extruded fibre-reinforced fastening band, and the buckle comprising:
- a body defining an inner chamber, and having first and second end walls to respective opposite ends of the inner chamber and defining first and second passages therethrough, which passages are contiguous with the inner chamber and which are adapted for receiving the locking portion of the elongate extruded fibre-reinforced fastening band therethrough, the body further having upper and lower walls to respective upper and lower sides of the inner chamber, the upper wall defining an access aperture therethrough such that the inner chamber is open to the upper side thereof;
- and
- a locking component located through the access aperture into the inner chamber, the locking component having at least one tooth for engaging the teeth on the first surface of the locking portion of the extruded fibre-reinforced fastening band, the locking component being resiliently biased into the inner chamber of the body so as to engage the teeth of the extruded fibre-reinforced fastening band when the fastener is formed in a closed loop.

A fastener comprising:
- an elongate fastening band comprising reinforced fibres, the elongate fastening band having a longitudinal axis and first and second planar surfaces, the longitudinal axis defining a longitudinal axis of the fastener, the reinforced fibres extending along the longitudinal axis, the first surface defining a plurality of teeth arranged substantially perpendicular to the longitudinal axis, and the second surface providing an engagement surface for the fastener, wherein the elongate fastening band has a first end region, and a locking portion which is spaced apart longitudinally from the first end region, the first end region and locking portion defining respective groups of such teeth on the first surfaces thereof;
- and
- a buckle fused with the teeth of the first end region of the elongate fastening band, the buckle and elongate fastening band being arrangeable to form a closed fastener configured to compress or clamp at least one article encircled by the elongate fastening band, and the buckle comprising:
- a body defining an inner chamber, and having first and second end walls to respective opposite ends of the inner chamber and defining first and second passages therethrough, which passages are contiguous with the inner chamber and which are adapted for receiving the locking portion of the elongate fastening band therethrough, the body further having upper and lower walls to respective upper and lower sides of the inner chamber, the upper wall defining an access aperture therethrough such that the inner chamber is open to the upper side thereof;
- and
- a locking component located through the access aperture into the inner chamber, the locking component having at least one tooth for engaging the teeth on the first surface of the locking portion of the fastening band, the locking component being resiliently biased into the inner chamber of the body so as to engage the teeth of the fastening band when the fastener is formed in a closed loop,
- wherein the fastening band comprises a first polymeric material and the body comprises a second, different polymer material.
