Abstract

A gardening tool handle comprising a shaft which is shaped to an angle and which is offset with regard to the centre line of tool attachment. In use, the upper extremity of the handle 1 is supported on the shoulder of the user and gripped by two side-mounted handles 2 and 3. The length of the handle is adjustable with a telescopic section 4. The angle of attack or pitch of the tool in relation to the ground may be changed with a screw adjustment 5. This feature also allows for the handle to be folded for transport and storage. The device is reversible for both right and left handed use. The handle has the facility of exchangeable tool heads.

Description

ERGONOMIC GARDEN RAKE AND HOE HANDLE

This invention relates to a ergonomically designed garden implement handle for the attachment of various rake and hoe ends.

The typically straight handle or shaft of tools such as the rake or hoe suffer from the disadvantage that the user tends to lean forwards and rotate the shoulders during use.

This results in back pain particularly due to lumbar muscle strain.

The purpose of this invention is to allow the user of the rake or hoe to stand upright and to eliminate the rotational movement of the shoulders and therefore the repeated twisting of the lumbar muscles.

This is achieved by the shaft being off set to one side (in a dogs leg shape) and held with two grip handles so that the centre line of the rake or hoe can be pulled straight towards to user thereby eliminating any rotational movement. The overall height of the handle is adjustable so the user can stand upright.

The angle of attack or pitch of the tool end is also adjustable since the handle can be angled in the mid section of the handle. This allows the user to vary the proportion of the force applied during raking or hoeing that is directed into the ground.

The handle is fully reversible to allow both left and right handed operation.

The handle can accept a variety of tool ends.

The handle is preferably made from plastic coated tubular steel with an internal leaf- spring type press button to adjust the height, allow reversibility and interchangeability of the tool ends.

Other materials such as plastics or composites could be used.

A preferred embodiment of the invention will now be described with reference to the accompanying drawing in which: Figure 1 shows the handle from the front but with the section below the angle of attack adjustment 5, partially rotated for clarity. The handle is shown extended.

Figure 2 shows the side profile, the handle is shown shortened.

Figure 3 shows an altemadve rake attachment for heavier ground work.

Figure 4 shows two types of hoe attachment.

Figure 5 shows a large volume leaf rake.

With reference to figure 1, which is shown in the right handed mode, the user rests the upper section of the handle shaft 1 on the right shoulder. The right right hand grips handle 2 so that the right forearm crosses and rests on the shaft enabling pressure to be applied at this point. The left hand grips handle 3. This arrangement aligns the centre of the selected tool with the centre of the users body.

The tool is then operated by pulling directly towards the user with no rotation of the spine.

Adjustment for height is made at 4 with the tube below this level sliding in or out of the tube above, being held in place by an internal leafspring press button type fitting.

The holes on the lower tube are drilled right through so the handle can be rotated 180 degrees at this level.

The side profile shown in figure 2 demonstrates the variable angle of the lower part of the shaft which is held at the chosen degree, by the fitting 5. Clockwise and anti- clockwise rotation can take place around point 5 for reversibility of operation. When released the handle can be folded over for ease of storage and transportation.

The desired tool end is inserted at 6, and locked in place with the same leaf-spring fitting as described above, again 180 degree rotation is provided here for reversibility.

Figures 1 and 2 show a lawn type rake end in position at 7, with alternative rake and hoe tools shown in figures 3, 4 and 5. The rake end in figure 5 is described as large volume and is especially designed for rapid collection of fresh leaf fall. The attachment is designed so it can be used with handle 9 if desired. With this option the grip is changed so that, while the handle is set in the same right handed position as shown in figure 1, the right hand grips handle 9 and the left hand grips handle 1. This then allows a backward sweeping motion with a greater leverage. A large volume of light fresh leaf litter is then passed to the left hand side of the user. This does induce some shoulder rotation but an upright stance is maintained. it is envisaged that this should be used when the leaf litter is fresh and dry with a low weight for any given volume.

The angle of attack or pitch,that the tool end makes with the ground is illustrated at 8.

With the handle set near straight at 5, the user can pull the attached tool end with more force being directed into the ground por any given level of exertion) as the handle tends to pivot on the shoulder at 1. By adjusting the handle at 5, the section of the handle below this level can be rotated away from the straight setting, the further it is rotated, the smaller the resultant angle 8. Since the handle will now tend to slide up the shoulder at 1 less force is directed into the ground for each rake or hoe stroke. This is ideal for spreading out finely crumbled soil such as raking in grass seed. Alternatively this allows a reduced energy expenditure per rake or hoe stroke ideal for prolonged raking and hoeing

Claims (7)

CLAI MS
1. A garden rake and or hoe handle, with handle shaft off set to one side ( in a dogs leg shape) from the centre line of tool attachment, supported by resting on the chosen shoulder and gripped by the user on two staggered, sided mounted handles, so that tool end can be pulled directly towards the user with no rotation of shoulders and therefore no repeated twisting of lower spine.
The handle is adjustable for both height and the angle of attack or pitch of tool ends, so that the user can stand upright eliminating the tendency to lean forwards when raking or hoeing.
2. A handle as in claim 1 which is fully reversible for left handed and right handed operation.
3. A handle as in claims 1 and 2 which can be folded for storage or transportation.
4. A handle as in claim 1 with detachable tool ends to allow the use of a variety of rake and hoe attachments.
5. A handle as in claimed in any preceding claim which allows the user by adjusting the angle of attack or pitch of the tool end,to vary the proportion of force that is directed into the ground during raking or hoeing for any given level of exertion to suit different types of raking or hoeing activity being undertaken.
6. A handle as claimed in any preceding claim which is made of plastic, metal, composites or any combination of the these materials.
7. A garden rake and or hoe handle as substantially herein described above and illustrated in the accompanying drawings.
