Portable gardening implement with adjustable safety handgrip

Abstract: A motorized portable gardening implement, particularly an edge trimmer of the whip type, includes a tool supporting head (2) that is rigidly coupled to the end of a handle (5) that has grip regions provided with antislip inserts (8, 9) or coverings made of flexible material and suitable to facilitate grip of the implement. One grip region is constituted by a handhold (7) that can be anchored to the handle (5) and can be adjusted angularly, longitudinally, and transversely to it. The advantages provided by this grip means are greater safety and great comfort and maneuverability.

Description: The present invention relates to a portable implement for gardening and similar activities, such as for example motorized nylon-whip edge trimmers, with an adjustable safety handgrip, of the type defined in the preamble of claim 1. Conventional garden tools of the above mentioned type satisfactorily perform their task but are susceptible of some improvements. Ordinary gardening tools have handgrips that are generally made of metal or rigid plastic. In the humid environment of gardens, or when the user's hands are dirty and sweaty, the handgrips can be slippery, making it difficult, awkward and most of all dangerous to use the tool. Furthermore, the handgrips of conventional portable power tools are generally anchored to the handle in fixed positions with no possibility of adjustment and adaptation to the user's size. US-A-2,263,431, which shows the features of the preamble of claim 1, discloses a device for cutting or trimming grass, foliage or the like, having a handle provided with hand grips made of rubber or other suitable material. The hand grips are coverings arranged over the handle. No inserts for the handle are disclosed. EP-A-0 284 659 discloses a vibration-damping control handle for a portable power tool in which the handle is provided with a rubber covering. No inserts for the handle are disclosed. The aim of the invention is to improve those implements by providing a portable implement that is safe in use, comfortable, ergonomic, and adaptable to the size of every user. This aim is achieved with a portable implement of the type defined in the introduction, characterized in that the handle has, at least in the grip regions, antislip inserts made of flexible material. Preferably, the flexible material is chosen among natural or synthetic rubbers or among very soft plastics. Furthermore, the inserts can have antislip raised portions or surface discontinuities. An implement with these characteristics offers the advantage of safe and easy grip for the user's hands even in the presence of moisture, sweat, or dirt. A preferred but not exclusive embodiment of an implement according to the invention is described hereinafter and is illustrated by way of non-limitative example in the accompanying drawings, wherein: Figure 1 is a side view of the implement according to the invention; Figure 2 is a partially exploded side view of the grip regions of the implement of Figure 1; Figure 3 is an exploded front view of a detail of the implement of Figure 1. With reference to the above figures, the implement according to the invention, generally designated by the reference numeral 1, includes a tool supporting head 2 with a rotary tool 3, for example of the nylon-whip type, actuated by a motor 4, for example of the electric type. Tool supporting head 2 is connected to a substantially rigid handle 5 provided with grip regions that include a first handhold 6 that is formed monolithically with handle 5 at its free end, and a second handhold 7 that is anchored on handle 5 at a distance from first handhold 6. According to the invention, both handholds 6 and 7 are provided with respective antislip inserts or coverings 8 and 9 made of flexible material, which are fixed to the grip regions and are meant to improve grip of the implement 1 on the part of the user's hands. The material of inserts 8, 9 can be chosen among natural or synthetic rubbers or among very soft durable plastics. The surface of inserts 8, 9 can be provided with series of raised portions, hollows, knurlings, and/or grooves 10 and 11 to further improve the grip of the implement. According to the invention, second handhold 7 is connected to handle 5 by an adjustable friction anchoring means. The anchoring means can be constituted by a substantially U-shaped bracket 12 that can be secured on the handle 5 in a position that is selected by the user. Bracket 12 can be connected to handhold 7 by a threaded pivot 13 that can be inserted in holes formed on the wings of the bracket and on which a securing handwheel 14 is screwed. Handhold 7 is provided with a connecting protrusion 15 with a transverse through hole 16 for the insertion of threaded pivot 13. A series of angularly spaced and equidistant radial grooves 17 is formed on protrusion 15, peripherally with respect to hole 16. The grooves are suitable to cooperate with a series of corresponding grooves or discontinuities 18 that are formed on the internal surface of bracket 12, so as to lock handhold 7 in a desired angular position by securing bracket 12 with handwheel 14. Furthermore, series of grooves 19 are formed on the opposite sides of handle 5 and are slightly inclined with respect to the longitudinal direction. Grooves 19 cooperate with the internal surface of bracket 12 to lock it in a position that is preset both longitudinally and transversely with respect to handle 5. It has been found in practice that the implement according to the invention achieves the intended aim and in particular the fact is stressed that antislip inserts 8 and 9 allow comfortable and safe grip of the implement even in the presence of moisture and dirt on the grip regions thereof. Furthermore, the adjustability of handhold 7 in a longitudinal, transverse, and angular direction with respect to the handle allows the user to position the grip regions in an optimum and ergonomic manner, reducing the overall effort of the arms and making work more comfortable.

Claims: A motorized portable gardening implement, particularly edge trimmer of the whip type, comprising a tool supporting head (2) that is rigidly coupled to the end of a substantially rigid handle (5) that can be gripped by a user, characterized in that , at least in the grip regions, said handle has antislip inserts made of flexible material. Implement according to claim 1, characterized in that said flexible material of said inserts (8, 9) is chosen among natural and synthetic rubbers and among very soft plastics. Implement according to claim 1, characterized in that said inserts (8, 9) have raised portions and/or knurlings and/or surface discontinuities (10, 11) that are suitable to achieve improved and safer grip. Implement according to claim 1, characterized in that said grip regions comprise a first handhold (6) that is formed monolithically at the end of said handle (5), which has at least two of said inserts (8, 9) stably fixed to the opposite sides of said region. Implement according to claim 1, characterized in that said grip regions comprise a second handhold (7) that can be anchored to said handle (5) in an longitudinally, transversely, and angularly adjustable position. Implement according to claim 5, characterized in that said second handhold (7) is connected to said handle (5) by an adjustable friction anchoring means. Implement according to claim 6, characterized in that said adjustable friction anchoring means comprises a bracket (12) that can be secured around said handle (5) and can be connected to said second handhold (7) by a threaded pivot (13) with a securing handwheel (14).
