Binding device

Claim 2

A binding device comprising: a rigid base plate, a flexible ladder-like belt having a plurality of parallel spaced apart rungs provided between a pair of side rails thereof, said belt being hinged on an upper surface of said base plate near one end thereof, an outwardly inclined stopper formed at the opposite end of said base plate to protrude from the upper surface of said plate and away from said belt hinged point for selectively engaging one of said rungs, and a guide means provided on the upper surface of said plate between said hinged point and said stopper, being close to the stopper for use in guiding said belt toward the stopper permitting retention of the belt in binding position on the stopper.

Claim 3

A binding device as claimed in claim 1, wherein the free tip end of said belt forms an outwardly curved tongue.

Claim 4

A binding device as claimed in claim 1, wherein said belt is made of flexible nylon.

Claim 5

A binding device as claimed in claim 1, wherein said belt is made of flexible polypropylene.

Claim 6

A binding device as claimed in claim 1, wherein the length of said stopper is not greater than the distance between the inner sides of said side rails and the width of said stopper is not greater than the distance between adjacent rungs.

Claim 7

A binding device as claimed in claim 1, wherein said guide means comprises a pair of angle-shaped guide blocks, said blocks having horizontal legs that face one another and having a gap therebetween.

Claim 8

A binding device as claimed in claim 6, wherein said horizontal legs each have undersurfaces diverging upwardly from the stopper.

Claim 9

A binding device as claimed in claim 1, wherein said guide means comprises a guide block in the form of a channel through which said belt is inserted, said channel having an undersurface which diverges upwardly from said stopper.

Claim 10

A binding device as claimed in claim 1, wherein said base plate has a centrally located hole through which a pin is inserted to fix the device to a substrate.

Claim 11

A binding device as claimed in claim 1, wherein said base plate has an adhesive on the plate back surface for fixing the device to a substrate.

Claim 12

A binding device as claimed in claim 1, wherein said belt is hinged on to said base plate by a base rod formed parallel to said rungs, said rod being pivotally mounted in a slot formed on the upper surface of said base plate.

Claim 13

A binding device, comprising: a rigid base plate; a flexible ladder-like belt defined by a plurality of parallel spaced apart rungs provided between a pair of side rails thereof, said belt being hinged at its base end on to an upper surface of said base plate at a location close to one end thereof and having an outwardly curved tongue at its working end; an outwardly inclined stopper formed at the opposite end of said base plate, said stopper protruding from the upper surface of said plate and inclined away from said belt hinged location for selectively engaging one of said rungs; and a guide means provided on the upper surface of said base plate between said belt hinged location and said stopper and located in proximity to the stopper, said guide means comprised of a pair of angle-shaped guide blocks having horizontal legs that face one another and being adapted to guide said belt toward the stopper and retaining one of the belt rungs in a binding position on the stopper.

Claim 14

A binding device, comprising: a rigid base plate; a flexible ladder-like belt defined by a plurality of parallel spaced apart rungs provided between a pair of side rails thereof, said belt being hinged at its base end on to an upper surface of said base plate at a location close to one end thereof and having an outwardly curved tongue at its working end; an outwardly inclined stopper formed at the opposite end of said base plate, said stopper protruding from the upper surface of said plate and inclined away from said belt hinged location for selectively engaging one of said rungs; and a guide means provided on the upper surface of said base plate between said belt hinged location and said stopper and located in proximity to the stopper, said guide means comprised of a pair of angle-shaped guide blocks having horizontal legs that face one another and being adapted to guide said belt toward the stopper and retaining one of the belt rungs in a binding position on the stopper.
