Description

The invention relates to a device making it possible to trim a hedge vertically or horizontally without tiring the arms or the back, without injuring oneself while remaining on dry land.

It consists of a fixed rear wheel (2), a directional front wheel (3) with its handle (9) to perform the maneuvers, a wheel (10) on the left side of the device to keep the position at vertical level by with respect to the terrain, thanks to the adjustment handle (21), its bubble level (28), its chassis with extension to mount the cutting equipment in a vertical position on the chassis extension, or to mount the pole (29) on the frame extension (1), then reassemble the cutting equipment on the pole (29) for horizontal cutting, a handle (33) with its extension (34) for maneuvering, a screw brake (27) to immobilize the device.

The device according to the invention is particularly intended for trimming hedges.

The present invention relates to a mobile device for trimming a hedge on a horizontal height, as on each side of the hedge on a vertical height.

The tailor uses a stepladder, or else builds scaffolding to work at his height, because holding his hedge trimmer at arm's length is difficult and painful for the arms and back.

The device according to the invention allows the user to trim a hedge at the desired height without feeling tired and, moreover, remaining on solid ground.

A chassis is mounted on two main wheels: the rear wheel is fixed, the front wheel remains directional manually. This thus makes it possible to go along the hedge in parallel to make the size or to move the device.

A third smaller wheel is mounted on the left side of the device, a distance of several centimeters, and parallel to the fixed rear wheel.

A counterweight at the end of the joint prevents the device from tipping over.

This third wheel will keep the device vertical thanks to its articulation, manually adjustable relative to the terrain.

A bubble level is attached to the device.

An extension is attached to the chassis of the device.

At the end of this extension, equipment for vertical cutting can be installed.

This equipment is composed of a support receiving at one end the hedge trimmer, and at the other end a handle and a counterweight to balance the whole.

A main pivot fixed in the center of this support is mounted on the end of the extension. Once the vertical cutting has been completed, the equipment of the extension is dismantled, i.e. the pivot, a pole is then mounted at the end of it, then the equipment is reassembled (i.e. the pivot on the pole for horizontal cutting).

The handle will then be reassembled opposite the equipment. An extension is provided at the end of this handle for high cutting.

A screw brake is attached to the chassis to immobilize the device.

The various accompanying drawings illustrate this invention.

Figure 1 shows the horizontal cutting.

Figure 2 shows the vertical cutting.

Figure 3 shows the device in rear view. 30

With reference to these drawings, the device comprises a chassis (1) mounted on two main wheels (the rear wheel being fixed (2) and the front wheel being directional (3)). The latter is directional thanks to its pivot placed inside the tube (4) and fixed to the frame (1). A lug fixed on the steering (5), with its axis (6) and its rod (7) will be able to control the direction of the front wheel.

-2A notched part of the rod (7) passes through an orifice (8) half-notched inside; it is fixed to the chassis.

The rod (7) ends with a handle (9) used to operate the device.

By lifting this handle (9), the notches of the rod (7) are released. Management becomes free.

By letting the handle (9) descend by its own weight, the notches again lock the steering.

Then there is a third wheel of smaller diameter (10), with a central axis extended by an arm (11) and welded to the shaft (12).

This shaft (12) has an articulation (13) connected to two uprights (14) and it fixed to the chassis (1).

This shaft (12) has another articulation (15) which is also fixed to the chassis. 10

A counterweight (16) is fixed to the end of the shaft (12).

Another shorter arm (17) welded to the shaft (12) will control the wheel (10) via a rod (18) with its articulation (19).

Part of this rod (18) is notched.

This notched part passes through an orifice (20) half-notched inside and is fixed to the extension of the chassis (1).

The rod (18) ends in a handle (21) used to hold the device vertically.

By slightly forcing this handle (21) on itself, right side, a rod (22) of rectangular shape welded to the rod (18), will press on the bearing (23). The notched rod (18) will move away from the half-notched orifice (20). As a result, the rod (18) is released. The apparatus can thus be adjusted vertically while holding the handle (21) for cutting.

As soon as one stops forcing the handle (21), the notches are re-locked by means of a bearing (24) fixed on a lever (25) at the end

At the other end of this lever (25), a new articulation connects the chassis (1)

One end of the spring (26) is fixed to the frame (1). The other end of the spring (26) is connected to the lever (25). Thanks to the spring (26), the bearing (24) always remains in abutment on the rod (18). The vertical locking is then maintained.

A screw brake (27) immobilizes the device.

The bubble level (28) allows you to check the stability of the device vertically. 30

For horizontal cutting, a pole (29) mounts at the end of the frame extension (1). The main pivot (30) must be mounted on the pole (29).

The pivot (30) receives all its equipment: support (31), hedge trimmer (32) mounted on

-3The support, cutting handle (33), extension on cutting handle (34), removable counterweight (35) for horizontal cutting.

For vertical cutting, it suffices to dismantle all of the equipment: the main pivot (30) of the pole (29); then the pole (29) at the end of the frame extension (1).

Then, the equipment is reassembled in the same way, that is, the main pivot (30) on the end of the frame extension (1).

The pivot (30) is mounted horizontally by means of a lug (36).

The counterweight (35) is mounted on the end of the support (31) intended for vertical cutting. This forms a balance in balance. By reversing the handle (33) opposite the support (31), we will switch to the vertical cutting mode. 10

To obtain a regular vertical cut, you can stretch a line parallel to the hedge and follow it with the directional wheel (3), using the operating handle (9).

The distance between the line and the hedge depends on the thickness to be cut.

The string can also be replaced by U-shaped iron bars placed on the ground from end to end. The main wheels of the device will roll inside the U (which then serves as a guide). There is no longer any need to take care of directing the device but only to always keep it vertical thanks to the bubble level.

For horizontal cutting, the cord or the U-shaped iron bars are not necessary. Just follow the hedge in parallel while respecting the vertical position thanks to the bubble level (28). 20
