Abstract
Abstract A gardening tool has a straight handle and a tool head, such as a spade blade, gardening fork or weeding fork, pivoted to its lower end about a transverse axis, stops limiting the pivotal movement of the tool head in one direction beyond normal working position, aligned with the handle, and in the other direction beyond a second position at an obtuse angle to the handle. A spring biases the tool head to working position and a pedal at the lower part of the tool enables foot pressure to be applied to the tool head. A catch may be provided to hold the tool head releasably in its second position, and the tool head may be interchangeable with others.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
148 words
A gardening tool having a substantially straight and normally upright handle, a pedal connected to the normally lower end of the handle, a tool head, pivot means interconnecting said handle and the tool head whereby the tool head may be pivoted about an axis transverse with respect to said handle and tool head, and a torsion spring having a first part thereof fixed to the handle and a second part thereof fixed to the tool head with an intermediate part associated with the pivot means, the interconnection between the tool head and the handle by said pivot means being such that the tool head cannot be pivoted past a first position wherein the handle is in substantial alignment with the tool head and a second position wherein the tool head is at an obtuse angle to said handle, said torsion spring urging said handle toward the first position.
Claim 2
Dependent Claim
148 words
A gardening tool having a substantially straight and normally upright handle, a pedal connected to the normally lower end of the handle, a tool head, pivot means interconnecting said handle and the tool head whereby the tool head may be pivoted about an axis transverse with respect to said handle and tool head, and a torsion spring having a first part thereof fixed to the handle and a second part thereof fixed to the tool head with an intermediate part associated with the pivot means, the interconnection between the tool head and the handle by said pivot means being such that the tool head cannot be pivoted past a first position wherein the handle is in substantial alignment with the tool head and a second position wherein the tool head is at an obtuse angle to said handle, said torsion spring urging said handle toward the first position.
Claim 3
Dependent Claim
70 words
A gardening tool as claimed in claim 1 wherein there is provided a bifurcated member at the normally lower end of the handle, said bifurcated member and said tool head in the upper region thereof being formed with aligned apertures, and said pivot means comprises a pivot bolt passing through said aligned aperatures, the intermediate part of the torsion spring being coiled around a lateral extension of said pivot bolt.
Claim 4
Dependent Claim
61 words
A gardening tool as claimed in claim 1 where the tool head is a weeding fork, comprising curved spaced points which extend into the ground adjacent the weed, and a curved fulcrum member attached to the rear of said tool head, said fulcrum facilitating rolling movement of said tool head from said first to said second position for removing the weed.
