DE19700286A1 - Leaf spear for clearing away of leaves - Google Patents

Abstract

The leaf spear comprises a base module (1) with spikes (2) and is connected to a handle (4) by a connector (3) or handle holder. The base module can be made of various materials, such as wood, metal or plastics, or a combination of these. The module can be adapted to defined tasks and can have another shape and another size. For example it can be longer, wider, round, angular, and the sides can run to a point, or be bevelled or rounded.

Description

State of the art in the field

The elimination of the z. B. fallen autumn leaves in the area of green areas z. B.

• a) done by hand,

where the z. B. leaves, usually individually by one Person.

This work performance is mostly necessary kneeling posture, uncomfortable and on austere.

For older and possibly also people with of a disability is particularly stressful. Time consuming as almost every sheet is removed individually / must be lifted.

With kneeling posture is normally achievable Working area limited to arm length. Ongoing Changes in the workplace exclude damage the green areas or green area

• b) by means of a rake

with pulling movements z. B. with a rake  Pile leaves on a collection point. The pulling movements depend on the e.g. B. Size of the existing area to be subtracted existing plants, shrubs, your own stand location to the collection point and are factors Factors that make work performance and work possible hinder and / or restrict.

• c. using a leaf broom.

Work - work areas - work performance - disabilities etc. differ only slightly from the previously described work performance with a rake (b)
The removal of the z. B. Laubes with one

• d. motorized suction systems.

The devices require requirements such as tech knowledge and in certain cases that Presence of an electrical connection to the Operation of the electr. Extraction system.

Unsuitable for elderly and disabled people as well as for young people. Unsuitable for transportation to more distant locations areas of application (e.g. cemeteries). Relatively high maintenance / purchase costs.

Task

Creating a simple, inexpensive, easy ten auxiliary device for the removal of z. B. foliage, in as comfortable, upright as possible, rights, labor and employment attitudes.

For often small, not easily accessible garden or other green areas (e.g. to the graves care) for an unrestricted group of people. (e.g. also for older and / or disabled people and young people).  

Task solution

"The leaf spike" as an auxiliary device for cleaning of green areas.

Opportunity to work in a more upright, ste posture.

Easy, simple handling of the device light weight and small dimensions By changing the length of the handle also larger ones Working area.

Little effort. Only light pressure of the device on z. B. the leaves to be picked up Larger green areas can be cleaned by z. B.
Bringing the leaves to be removed to a collection point using a rake and / or a leaf broom.

Easily pick up the foliage using a foliage pike.

Easy space-saving disposal of the by Already slightly pre-compressed foliage in also standing posture in a disposal container. (Bucket / sack / box etc.)

Better working area thanks to selectable handle lengths also with the use of already commercially available offered standard handle holders including also the extendable models. working area are seen from the work point of view hen, in every direction, expanded.

A certain shape enables / secures by z. B. beveling and / or rounding in the front area of the base module ( 1 ) also problem-free applications up to the far corners. Simple construction - simple materials - small construction size and weight, enable usability in remote areas (e.g. grave care / cemetery) etc.

It is shown as a simple example in:

Fig. 1 A basic module ( 1 ) / plate (top view) A basic module in a small form with a tapered front side to expand the work area up to / in distant corners,

Fig. 2 A basic module ( 1 ) / plate (section AB) In a small form with bevels to extend the working area, even in the far corners.

Fig. 3 A simple connection module ( 3 ) handle holder ( 3 c) consisting of a screw-on mounting plate with a welded-on handle tube ( 3 d). For easier handling, the handle tube is arranged in an inclined position. As a result, improved, easier uses in areas under plants or other obstacles within reachable distances.

It means:

( 1 ) The basic module / (needle holder)
( 2 ) The needles / skewers
( 2 a) The needle holder
( 2 b) Free needle length
( 3 ) Connection module / stick holder
( 3 a) Connection module base plate
( 3 b) screw connection of the base plate ( 3 a) to the base module ( 1 )
( 3 c) Handle holder
( 3 d) Screw / hole for attaching the handle
( 4 ) handle (here simple round wooden handle).

Claims (8)
