DE3319669A1 - Scarifying rake on two wheels for the working of lawns with a labour-reducing lever function - Google Patents

Abstract

Scarifying rake on two wheels for the working of lawns with a labour-reducing lever function. The appliance is equivalent to a balance beam with two unequal levers. The smaller lever is the working part x with the rake (3) and the wheel mounting (5). The longer lever is the operating lever y. The centre of rotation for the levers is the point A. The wheel mounting (5) and the housing plate (1) are in one piece. The point A is located exactly vertically above the wheel axle (7). This arrangement allows an easy height and depth adjustment for the rake (3) which is mounted on the housing plate (1) at the front. The wheels (6) are well proportioned in relation to the appliance in terms of their diameter, so that the appliance can be pulled very easily by means of the rolling lever force of the wheels (6). So that the wheels (6) remain adhering closely to the ground under different ground conditions, the rake is equipped with a ballast pan (9a) which can be filled either with sand or with stone from the garden terrain. Metal pieces can be pushed into the ballast space (9) underneath the housing plate (1). <IMAGE>

Description

Description for the Verlicutierrecher on 2 wheels for processing

turf with labor-reducing lever function.

In the two drawings attached to the application, the Scarifying rake ai <2 wheels shown.

Derd scarifying rake on 2 wheels with labor-reducing rake Lever function, is used for phase ventilation and moss removal. He exists from the working part x with the housing plate (1) to that of the rake (3), the handle holder (4) and the wheel holder (5) are attached. The housing plate (1) and the wheel holder (5) are made from one piece. Working part y consists of the stem (8), the used to pull the device and to adjust the height and depth of the rake (f) will. The wheel holder (5) takes the wheel axle (7) with its two wheels (6) in itself. At the upper end of the wheel holder (5) is point A. To the left of the point A is the working part x. To the right of point A is the stem.

This arrangement is to be regarded as a balance with unequal lever arms, where the point A represents the lifting pivot point.

If the handle (8) is pressed down at its outer end, it lifts the rake (3) from the ground, the other way around, pushes up the handle (8) the rake (3) with its tines into the ground. So one becomes easy to use Height adjustment of the rake works.

The wheel diameter of the wheels (6) is selected proportionally to the device so that that the wheels (') produce a rolling leverage when the device is pulled. the Roller lever force makes it easier to pull the rake. It rests on the wheels (6) Weight of the rake.

Because the dead weight of the rake is not the same for every condition of the bed The rake is sufficient to keep the rake always firmly on the ground equipped with a ballast tray (9a). The bowl can be made with sand or stones can be filled from the garden, so that the device adheres better to the ground reach.

The ballst shell saves the user of the device own strength to push the device to the ground.

The scarifying rake on 2 wheels for tilling lawns with a labor-reducing rake The lever function is opposite to all existing scarifying devices without wheels and with rakes, which are operated by hand, an enormous improvement, since the rake of the device is mounted far from the wheels and therefore a good and slight height and depth adjustment made possible by the handle the wheel diameter is chosen so that the wheels roll well in proportion to the device Have leverage and thus make pulling the device much easier. With existing For devices of the same type, the wheels are decidedly smaller. Also is the rake in other devices mounted exactly under the R-roof, this has the disadvantage that the height of this rake can only be adjusted using adjusting screws ann. Resistance to the ground, such as stones, etc., becomes an evil. A burden ballasted devices cannot be carried out successfully.

Reference numerals - List 1 - 'a The verticutter on 2 wheels ziir Processing of lawns with labor-reducing lever function consists of the Parts as they can be seen from the 2 attached drawings.

The housing plate (1) and the wheel holder (5) are made in one piece manufactured. The handle holder (4) is attached to the housing plate (1). The rake (3) is attached to the front of the housing plate (1). To stabilize the device a reinforcement plate (2) is mounted under the housing plate (1). The wheel mount (5) takes the loader axle (7), rn which the two wheels (6) are attached, in itself on. The handle (8) is firmly pushed into the handle holder (4). The cavity of the is formed under the housing plate (1) by the reinforcement plate (2), can can be used as space for ballast (9). A ballast shell (9a) is from the outside attached to the housing plate (1).

Claims (1)

P a t e n t a n s p r u c h The scarifying rake on 2 wheels for Cultivating lawns with a lever function that reduces the workforce is d a d u r c h e k e k e n n n n e i c h n e t that he is schematically a balance beam with 2 unequal Levering is the same. The smaller lever is the working part (x) with the rake and the Wheel mount. The longer helm is the service handle (y). The pivot point for the lever is point A in the attached drawing. Point A is exactly vertically above the Radachsed (7). This arrangement enables a slight height and depth adjustment allows for the rake. The diameter of the wheels (6) is opposite the device well proportioned, so that the rolling leverage of the wheels (6) Device can be pulled very easily. So that the wheels (6) stay well on the ground in different ground conditions Stick to the ground, the rake is equipped with a ballast tray (9a) which can optionally be filled with sand or stines from the garden area. In the Metal pieces can be inserted in the ballast space (9) under the housing plate (1).
