Abstract

A gardening shears comprises a first blade ( 10 ) and a second blade ( 20 ) which are provided with respective hand grips ( 12, 22 ), respectively, and are rotatably connected to one another via a pivot connection ( 13, 23, 30, 41 ). The pivot connection comprises a pivot bolt ( 32 ) passing through respective bores ( 13, 23 ) of the first and second blade ( 10, 20 ), respectively and secures the blades ( 10, 20 ) in axial direction of the pivot bolt ( 32 ) to one another. The pivot bolt ( 32 ) comprises in its axial direction successive first and second peripheral sections ( 34, 35 ), the first peripheral section ( 34 ) being rotatably mounted over a limited angular region within the bore ( 13 ) of the first blade ( 10 ) whereas the second peripheral section being non-rotatably secured within the bore ( 21 ) of the second blade.

First claim

The invention claimed is:

1. Garden shears comprising:
a first blade and a second blade having respective hand grips and pivotably mounted to one another by a pivot connection, wherein the pivot connection comprises a pivot bolt passing through respective bores of the first and second blades and rotatably secures the blades to one another in the axial direction of the pivot bolt, wherein:
the pivot bolt comprises, in its axial direction, successive first and second peripheral portions;
said first peripheral portion being disposed in the bore of the first blade and the second peripheral portion being disposed in the bore of the second blade, wherein the second blade is non-rotatable about the second peripheral portion of the pivot bolt and the first blade is rotatable relative to said second blade about the first peripheral portion of the pivot bolt over a limited angular range defined by a radial extension of the bore of the first blade;
wherein the first peripheral portion of the pivot bolt comprises a substantially circular cross section, and the second peripheral portion comprises at least a flat which engages with a corresponding flat of the bore of the second blade, whereas the pivot bolt includes a projection extending from the first peripheral portion and is received within the radial extension of the bore of the first blade; and
wherein the pivot bolt comprises, at its end adjacent to the first peripheral portion, a radially projecting flange in abutment with a surface of an outer main surface of the first blade, and wherein the projection is formed by a pin extending axially through the flange into a region adjacent to the first peripheral portion.

2. The garden shears as claimed in claim 1 , wherein the first peripheral portion and the second peripheral portion have an axial length which substantially corresponds to a thickness of a material of the first and second blades, respectively, in the region of the bore of the first and second blades.

3. The garden shears as claimed in claim 1 , wherein the pivot connection further comprises a second portion having a flange with a surface which abuts on an outer main surface of the second blade.

4. The garden shears as claimed in claim 3 , wherein the pivot bolt comprises at its end adjacent the second peripheral portion a threaded bore, whereas the second portion of the pivot connection comprises a threaded stud which is screwed into the threaded bore.

5. The garden shears as claimed in claim 3 , wherein the pivot bolt is provided with a threaded portion constituting an extension of the second peripheral portion, a threaded nut positioned on the outer main surface of the second blade and forming the second portion of the pivot connection being screwable onto the threaded portion.

6. The garden shears of claim 1 , wherein the radial extension of the bore of the first blade is defined by a first end wall extending radially outward, a second end wall extending radially outward, and a third wall extending circumferentially between the first and second end walls.

7. The garden shears of claim 6 , wherein contact between the projection of the pivot bolt and the first and second end walls of the radial extension of the first blade defines the angular range of rotation of the first blade relative to the pivot bolt and the second blade.
