Description

Modular leaf catcher system for tool comprising a slender tubular part FIELD OF INVENTION

The present invention relates to systems for collecting elements on the ground, in particular leaves, such as rakes or lawn brooms, allowing the user to move and collect leaves.

The present invention aims to constitute a sheet collection system which is particularly practical to use.

STATE OF PRIOR ART

Leaf sweeping systems are known which also do not allow leaves to be collected. In particular, the user must use a second tool once he has completed his sweep, for example to throw away the leaves that he has concentrated in a pile.

It is also known to overcome this problem, of collection with the same tool as that allowing sweeping, from patent FR2791518 which describes a gardening tool having a system of movable teeth between open and closed positions for collection.

This solution is nevertheless not very detailed and those skilled in the art are unable to implement it without encountering new technical problems to be resolved: ergonomics of gripping the handle, ease of maneuverability of the mechanism, lightness of the system, force to apply to maintain a closed tooth system to move an assembly to be picked up.

The invention aims to overcome at least some of the aforementioned drawbacks and to propose a leaf collection system capable of combining advantages of ergonomics, simplicity and practicality for its implementation, and this with materials and mechanisms modernized compared to the state of the art.

The subject of the invention is a leaf collector system comprising a first toothed tool forming a lawn broom, and having a tip configured to accommodate a handle, the system comprising:

-a second toothed tool configured to be assembled opposite said first toothed tool, said second toothed tool being pivotally mounted between an open position in which the first and second toothed tools are spaced apart from each other and a closed position in which the first and second toothed tools are in contact with each other; And
- means for driving said second toothed tool, comprising a connecting rod connected by pivot connections on the one hand to a handle and on the other hand to the second toothed tool, the handle being translatable on said handle, and configured to allow pivoting of the second toothed tool.

According to a general definition of the invention, the tip is arranged set back relative to the longitudinal axis of the first toothed tool, and forms an offset configured according to a geometric relationship chosen between the handle, the handle and the drive means to reduce the effort necessary to move the second toothed tool from the closed position to the open position and vice versa, and in that the handle comprises a slender light of chosen dimension configured to accommodate stopping means capable of limiting the stroke of the handle on the handle.

Surprisingly, the system according to the invention makes it possible to facilitate the transition from the lawn broom to leaf collector state while reducing the stroke of the handle and the effort required by the user to close the system according to the invention in use.

Preferably, the stopping means capable of limiting the travel of the handle on the handle belong to the group formed by screws screwed perpendicularly to the handle, any elongated fixing system configured to protrude perpendicularly to the axis of the handle.

Advantageously, the assembly formed by the second toothed tool and the fixing mechanism are configured to be removable.

According to one embodiment of the invention, the system according to the invention is configured in that at least one of the parts belonging to the group formed by second toothed tool, connecting rod, handle, is made of molded plastic material.

DETAILED DESCRIPTION OF THE FIGURES

With reference to Figures 1 to 6, the system comprises a fixed part comprising a first toothed tool 19 forming a lawn broom, having a tip 21 configured to accommodate a substantially tubular handle 3 for sweeping and grouping the leaves.

By lawn broom we mean any raking tool with elongated teeth allowing elements to be grouped together on a chosen surface.

The handle 3 has one end fitted integrally into the tip 21 of the first toothed tool 19.

The tip 21 is configured to be securely placed on the rear face of the first toothed tool 19, so as to create an offset between the longitudinal axis of said first toothed tool 19 and the longitudinal axis of the handle 3 inserted in said tip 21.

For example, the end piece 21 may include a tubular cavity into which the end of the handle 3 is inserted by force.

Alternatively, the end piece may comprise a deformable sleeve capable of receiving the end of the handle 3 and allowing it to be fixed in said end piece.

According to one embodiment of the invention, the first toothed tool 19 can also comprise acrylonitrile butadiene styrene, since this plastic is particularly resistant to mechanical stress and this tool 19 is heavily stressed when it comes into contact with the ground.

The system according to the invention further comprises a removable mobile part, configured to be mounted on the fixed part in order to transform the fixed part into a sheet catcher.

The mobile part comprises a second toothed tool 17 configured to be assembled opposite said first toothed tool 19 via fixing means allowing the pivoting of said second toothed tool 17 along a chosen axis and allowing it to oscillate manually between a so-called closed position or the first toothed tool 19 and the second toothed tool 17 are in contact with each other on their distal end relative to the handle 3 and substantially parallel, and a so-called open position, or the distal ends of the first toothed tool 19 and second toothed tool 17 are separated by a chosen distance.

In the closed position of the system, the leaves are held by pinching, which allows them to be lifted and thrown into a trash can.

The open position of the system makes it possible to release the sheets trapped between the two toothed tools 17,19.

For example, the second toothed tool 17 is pivotally mounted thanks to at least one finger hinge 20.

According to one embodiment of the invention, the first toothed tool 19 and second toothed tool 17 are joined by two pivot connections formed by two finger hinges 20 located offset on either side of the axis of the handle 3 .

According to one embodiment of the invention, the second toothed tool 17 is substantially flat.

According to another embodiment of the invention, the first and second toothed tool 19,17 are substantially flat, so that the closed position of the system is spatially space-saving.

The system further comprises a drive mechanism 5.15 of said second toothed tool 17 comprising a movable tubular handle 5 configured to be mounted on the handle 3 according to a chosen stroke, a connecting rod 15 connecting the second toothed tool 17 to said handle 5 thanks to pivot connections 14,23 on the one hand the handle 5 and on the other hand the second toothed tool 17.

Advantageously, the handle 5 is mounted in translation on the handle 3,

The connecting rod 15 is dimensioned so as to limit the stroke necessary for actuation of the system, for example to a stroke of one hundred and sixty millimeters along the handle 3, so that the user does not have to lean into a position uncomfortable.

The handle 5 further comprises a slender light 51 of chosen dimension configured to accommodate stopping means 52 capable of limiting the travel of the handle 5 between two pre-established positions on the handle 3.

As illustrated, the pivot connection 14 of the handle 5 is on a lower end of the handle 5 so as not to hinder the user when gripping the handle 5, and the pivot connection 23 is located on the second toothed tool 17, as far as possible from the axis of rotation, so as to minimize the traction force necessary to close or open the pinch.

Handle 5 must therefore be pulled by the user to open the system.

Advantageously, the combination of the offset of the tip 21 dictating the longitudinal axis of the handle 3 and the arrangement of the drive mechanism 5.15 makes it possible to obtain a chosen geometric relationship making it possible to have in the closed position, a greater angle of action between the handle 3 and the connecting rod 15, so as to limit the necessary stroke of the handle on the handle 3. This angular difference due to the offset also allows a greater angular variation and therefore a reduction in the necessary stroke by the handle 5.

This combination also makes it possible to reduce the effort necessary to be produced by the user to apply sufficient pressure to hold the elements to be picked up in position between the first and second toothed tools 17,19.

For example, the system according to the invention is configured in that at least one of the parts belonging to the group formed by second toothed tool 17, connecting rod (15), handle 5, is made of molded plastic material.

According to one embodiment of the invention, the teeth of the first and second toothed tools 17,19 can intersect to limit their spacing and therefore the space they occupy.

All their teeth are then substantially straight and parallel on their main segment.

For this purpose, the teeth of the first and second toothed tools 17,19 are also preferably of substantially the same length.

According to a particular embodiment of the invention, the ends of the teeth are curved at an angle close to ninety degrees, so that the system can stand upright on its own on these tooth curves, which avoids the need a support against which to place the system or to place it on the ground.

The curvature of the teeth also allows for greater efficiency in recovering leaves from the ground.

According to a particular embodiment of the invention, the system may include elastic return elements for the automatic return to the closed position of the system.

In addition, the handle 5 includes at least one anti-slip element at its end.

In particular, two anti-slip elements are provided, made of acrylonitrile butadiene styrene, on either side of the handle 5, which prevent the user from slipping and facilitate the sliding movement of the handle 5 on along the handle 3

The system as described therefore allows a user to have a lawn broom type tool for grouping items to be collected and easily transformable in a modular manner into a leaf catcher by mounting a mobile part, while facilitating its use and by limiting the effort necessary by the user to apply sufficient pressure on the elements to be picked up and ensure their immobility during movements by said user.
