Abstract
The invention comprises a rake that functions in the same position both when pulled and pushed and its stiff tines (39) are flexibly (9) pivoted or fastened with a spring (9) onto the rake head (16) that consists of an axle (16) made of a tubular section that is open is one side and the tines (39) have double ends (17).
Claims10
A rake comprising:
- a handle;
- a rake head associated with the handle;
- and
- a plurality of stiff tines extending from the rake head, with which, when the rake head stays in a working position, the rake is configured for a user to rake both with pulling and pushing motions,
- wherein each tine of the plurality of stiff tines comprises a flexible part, wherein each flexible part attaches a corresponding stiff tine to the rake head, wherein the flexible part is made of a thinner material layer than the corresponding stiff tine,
- wherein each stiff tine is independently flexible relative to the rake head at the flexible part, and wherein the flexible part's flexibility is such that the pressure on the tines from pushing and pulling of the rake bends the tines at the flexible point at a minimum of a 45 degree angle forwards and backwards from a resting position of the stiff tines, wherein the bending caused by pushing and pulling is configured to collect a load or loose objects, and
- wherein the stiff tines comprise first and second tine ends extending in opposite directions away from a respective stem of the tines to define double-ended tips, wherein the first and second tine ends are arranged one after another in a principal raking direction, and wherein, when in a resting position, the first and second tine ends each form greater than 90-degree angles relative to the ground, and wherein, when the rake is in a working position, the rake handle is at a 45-60 degree angle to the ground.

A rake comprising:
- a handle;
- a rake head associated with the handle;
- and
- a plurality of tines, wherein each tine of the plurality of tines extends individually from the rake head;
- wherein each tine has a flexible part which causes the tine to be independently flexible relative to the rake head;
- and wherein a respective first tine end and a respective second tine end extend in opposite directions away from each other and thereby form a respective double-ended tip of each tine, wherein the first tine end and the second tine end are arranged one after another in a principal raking direction;
- wherein the rake is configured such that when the rake head is held at a fixed orientation relative to the ground and pulled, the flexible part of each tine flexes in a first direction which positions the first tines properly for raking;
- and
- when the rake head is held in the fixed orientation and pushed, the flexible part of each tine flexes in a second direction that is opposite the first direction and which positions the second tines properly for raking, and
- wherein each tine comprises:
- a respective stiff part;
- and the flexible part that connects the stiff part to the rake head and permits independent flex of each stiff part, wherein the flexible part is made of a thinner material layer than the corresponding stiff tine.
