Clamp for fastening grapevines and other fruit-bearing shrubs on bracing wires

Claim 2

A clamp for fastening grapevines and other fruit-bearing shrubs onto a bracing wire, comprising a pair of angularly connected arms, each of said arms having a free end forming an intermediate piece; a detent connected at the free end of one of said arms for engagement thereof with the bracing wire; said detent being in the form of an arc member starting from said one end of said one arm and extending for a predetermined distance in a plane containing said one arm; the other end of said arc member approaching said one arm but spaced therefrom in said last-mentioned plane a predetermined distance less than the diameter of the bracing wire; a hook connected at the free end of the other of said arms for engagement thereof with the bracing wire; and, said intermediate piece being formed from a resilient material with said two arms being angularly spaced from each other with an obtuse angle whose apex is the straight directional lines extension of said two arms.

Claim 3

The clamp according to claim 1, wherein said detent and said hook project perpendicularly from a plane formed by said two arms.

Claim 4

The clamp according to claim 1, wherein said detent and said hook are positioned on the same side of a plane containing said two arms.

Claim 5

The clamp according to claim 1 or 3, wherein said detent and said one arm are positioned in a common plane.

Claim 6

The clamp according to claim 1, wherein said detent is in the form of an arc and has a first end connected with said one arm and a second end spaced from said one arm; the extent of the spacing of said second end from said one arm being less than the outer diametrical extent of the bracing wire; and, the maximum diametrical extent or width of said arc is greater than the outer diametrical extent of the bracing wire for embracement thereof with clearance.

Claim 7

Clamp according to claim 1, including: a spring-like extension connected with said other end of said arc member and extending in a plane parallel to a plane containing said arms and positioned on the same side of said intermediate piece having the obtuse angle between said arms.

Claim 8

The clamp according to claim 1, wherein said two arms of said intermediate piece are angularly related and lengthwise dimensioned to form a spacing between the apex of the obtuse angle and the bracing wire when the bracing wire is held in a stress-free condition by said detent and said hook which spacing is less than the diameter of the vine to be engaged.

Claim 9

The clamp according to claim 1, wherein said obtuse angle is between 120 and 150 degrees.

Claim 10

The clamp according to claim 1, wherein each of said two arms have different lengths.

Claim 11

The clamp according to claim 9, wherein said detent is provided at the end of said short arm and said hook is connected at the end of said long arm.

Claim 12

The clamp according to claim 1, wherein said hook together with said other arm forms an acute angle in a plane extending through said arms, said acute angle being arranged on the side of said other arm remote from said obtuse angle.

Claim 13

The clamp according to claim 1, wherein said hook is L-shaped.

Claim 14

A clamp for fastening grapevines and other fruit-bearing shrubs onto a bracing wire, comprising a pair of angularly connected arms, each of said arms having a free end and together forming an intermediate piece; a detent connected at the free end of one of said arms for engagement thereof with the bracing wire; a hook connected at the free end of the other of said arms for engagement thereof with the bracing wire; and, said intermediate piece being formed from an elastic plastic material with said two arms being angularly spaced from each other by an obtuse angle formed at their intersection; said detent being in the form of an arc member starting from said one end of said one arm and extending for a predetermined distance in a plane containing said one arm; the other end of said arc member approaching said one arm but spaced therefrom in said last-mentioned plane a predetermined distance less than the diameter of the bracing wire; the inside diameter of said arc being greater than the diameter of said bracing wire; and, a spring-like extension connected with said other end of said arc member and extending in a plane parallel to a plane containing said arms and positioned on the same side of said intermediate piece having the obtuse angle between said arms.

Claim 15

A clamp for fastening grapevines and other fruit-bearing shrubs onto a bracing wire, comprising a pair of angularly connected arms, each of said arms having a free end and together forming an intermediate piece; a detent connected at the free end of one of said arms for engagement thereof with the bracing wire; a hook connected at the free end of the other of said arms for engagement thereof with the bracing wire; and, said intermediate piece being formed from an elastic plastic material with said two arms being angularly spaced from each other by an obtuse angle formed at their intersection; said detent being in the form of an arc member starting from said one end of said one arm and extending for a predetermined distance in a plane containing said one arm; the other end of said arc member approaching said one arm but spaced therefrom in said last-mentioned plane a predetermined distance less than the diameter of the bracing wire; the inside diameter of said arc being greater than the diameter of said bracing wire; and, a spring-like extension connected with said other end of said arc member and extending in a plane parallel to a plane containing said arms and positioned on the same side of said intermediate piece having the obtuse angle between said arms.

Claim 16

The clamp according to claim 13, wherein said detent and said hook project perpendicularly from a plane formed by said two arms.

Claim 17

The clamp according to claim 13, wherein said detent and said hook are positioned on the same side of a plane containing said two arms.

Claim 18

The clamp of claim 13, wherein said obtuse angle is between 120 and 130 degrees.

Claim 19

The clamp according to claim 13, wherein said detent and said one arm are positioned in a common plane.
