Description

Handlebar for garden equipment

Technical field

The technical solution relates to the field of motor garden technology, in particular to the handlebars having at least one means for securing at least one accumulator battery, preferably at least one starter battery of an internal combustion engine.

BACKGROUND OF THE INVENTION

Motorized garden equipment usually consists of a ground-mounted chassis fitted with wheels, some of which may be powered; in the case of technology for winter use, the chassis may also be equipped with a crawler chassis. An electric or internal combustion engine driving knives, milling cutters or other tools, and, if necessary, equipment travel, is mounted on the chassis. Further, for operating the gardening equipment, the handlebars are fastened with their lower part to the chassis and provided with a handle (s) on their upper part for holding the user's hands while driving / operating the gardening equipment. The handlebars generally further comprise the operating controls (electrical switch, throttle lever, travel speed switch, etc.) in a position such that they are conveniently reachable by the hands of the user, preferably at the top of the handlebars.

Recently, motor garden equipment equipped with other electric equipment, such as lights, horn, and especially the technology with internal combustion engines equipped with so-called electric start, is being started, instead of the usual starting line for initial spinning of stationary internal combustion engine. This brings a significant increase in comfort as well as the possibility of using this technique by physically less fit individuals, eg seniors. All this technique requires the use of an electric rechargeable battery.

The electric battery is normally placed directly on the chassis, for example, behind the engine under the handlebars, by means of a caliper or bracket, or is inserted into the receptacle. There is also a need for a starter switch, for example in the form of a key switch provided with a key, which is placed on the handlebars within easy reach of the user or switches of other electrical equipment.

Such an arrangement with placing the battery directly on the engine chassis presents considerable drawbacks since the battery is exposed to the weather, especially rose, moisture, snow and dirt. It is also directly affected by vibration and heat from the engine, reducing its capacity and service life. Electrical wiring (eg battery-starter-starter) is relatively long, which increases resistance and loss, and a long section of wiring (eg battery-starter) is permanently energized, which can increase the risk of fire of the stored machine, especially in the case of folding handlebars. Dirt collects around the battery, which does not appear aesthetically pleasing and makes it difficult to clean the chassis from grass, dust, etc. On mowers, the battery may limit the location of the ejection tunnel.

The essence of the technical solution

The object of the present invention is to overcome the above-mentioned and other disadvantages and to provide improved handlebars increasing the utility value of the gardening equipment (machines) on which they are used.

Gardening means, without limitation, any machine driven / guided / operated by the handlebars, whether with an electric or internal combustion engine, with or without travel, with wheels or belts, with or without the operator's seat, with interchangeable work tools or single-purpose, for summer and / or winter use. Examples include single- or multi-purpose mowers, aerators (scarifiers), mulchers, small tractors and snow throwers.

The essence of the invention consists of the handlebars applicable to motorized garden equipment, wherein the handlebars have at least one means for attaching at least one accumulator battery (hereinafter referred to as "the battery") thereon.

Another object of the invention is a kit comprising the handlebars described in more detail below and at least one rechargeable battery. In a preferred embodiment, at least one of the batteries is a starter battery of an internal combustion engine.

An essential advantage of the solution is that increasing the weight of the handlebar by attaching the battery to the handlebar increases the inertia of the handlebar and reduces the vibration caused by the forces applied to the handlebar from the engine. elements on the handlebar.

Handlebar means any handlebar commonly used in the art, i.e. at least one rigid structure, eg a straight or suitably shaped tube, mountable or resiliently mountable via at least one anti-vibration element, with its lower part on the chassis, and provided with a handle on its upper part Handles for holding the user 's hands while driving / operating garden equipment. The handlebars may preferably be adjustable in folding and / or height and / or lateral (especially horizontal handle pitch). This can be achieved by pivotable / flexible elements, such as removable or locked joints.

The handlebars can be of a variety of conventional types, such as with two handgrips for gripping the user's hands, where the grips have a suitable horizontal pitch and height above the ground for comfortable gripping / control by the user, each gripper mounted on the top (always considered in working position) a suitable length element, for example a straight or curved connecting tube, and the lower end of the connecting element is mountable on the chassis. For attachment to the chassis, each connecting element is provided with a suitable fastening element, which may be screws and nuts, a lockable hinge, screw holes, a fastening block with bores, etc. The handle may be a directly shaped / modified part of the connecting element, where Shaped plastic sleeve with thermal insulation, resp. anti-vibration properties.

The handlebar interconnecting elements may be connected to one another by one or more transverse elements, preferably horizontal. The transverse member may be a control panel described in more detail below.

Another conventional handlebar design comprises two handles mounted on the upper ends of two interconnecting members that converge symmetrically from the top ends and continue from a certain point as a single interconnecting member with one lower end attachable to the chassis.

Another type of handlebar construction is a single continuous connecting element in the form of a suitably shaped rigid open loop, the free lower ends of which are adapted to be attached to the chassis and the upper, at least one portion of the substantially straight and horizontal middle section of the loop serves as a handlebar. Collapsible handlebars of this type may consist of two rigid open loops connected to each other in a detachable manner. locking joints.

However, the technical solution is applicable without limitation to any shape or type of handlebar.

The anti-vibration elements may be a suspension of the handlebar at the location of the handlebar fasteners for attachment to the chassis or elsewhere on the handlebar or handle, for example by metal springs and / or anti-vibration material and / or vibration absorbing material applied to the surface; in the handlebar tube cavity. An example of a handlebar suspension at a chassis mounting point is a rubber silentblock with molded mounting bolts.

As a rule, the handlebars have at least one rechargeable battery mounted thereon in the assembled state as in the operation of the machine. The battery is of any suitable charging type, preferably a closed (maintenance-free) type. By way of example and without limitation, lead (Pb), nickel-cadmium (NiCd), nickel-metal hydride (NiMH), nickel-iron (Ni-Fe), nickel-zinc (Ni-Zn), silver-zinc, lithium- ion (Li-ion) and lithium polymer (Li-Pol) type.

In one embodiment, at least one of the batteries is a starter battery of an internal combustion engine, and the term "starter battery" refers to a battery usable for starting a garden engine internal combustion engine. In other embodiments, the battery is usable for power
