Description

Technical field

The invention relates to the field of motorized garden technology, in particular to handlebars having at least one means for attaching at least one accumulator battery, preferably at least one starter battery of an internal combustion engine.

BACKGROUND OF THE INVENTION

Motor gardening equipment usually consists of a frame moving on the ground, equipped with wheels, some of which may be driven; in the case of winter applications, the frame may also be equipped with a crawler undercarriage. An electric or internal combustion engine driving knives, milling cutters or other tools and, where appropriate, the chassis of the technology is mounted on the frame. To operate the gardening equipment, the handlebars present are fastened by their lower part to the frame and provided with a handle (s) on their upper part for holding by the user's hands when driving / operating the gardening equipment. As a rule, the handlebars further comprise operating controls (electrical switch, throttle lever, switching speed, etc.) in a position such that they are conveniently reachable by the hands of the user, preferably at the top of the handlebars.

Recently, the production of motorized garden equipment equipped with other electrical equipment such as lights, a horn, and especially the technology with internal combustion engines equipped with so-called. By means of an electric start, that is, instead of the usual starting line for the initial spin of a stationary internal combustion engine, the motors are provided with an electric starter. This brings a significant increase in comfort as well as the possibility of using this technique by physically less fit individuals, e.g. seniors. All this technique requires the use of an electric rechargeable battery.

The electric battery is normally placed directly on the frame, for example, behind the engine under the handlebars, by means of a caliper or bracket, or is placed in a box. A starter switch, e.g. in the form of a key switch, which is placed on the handlebars within easy reach of the user, or switches of other electrical equipment are required.

Such an arrangement with placing the battery directly on the engine frame presents considerable disadvantages, 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. The electrical wiring (eg battery - switch box - starter) is relatively long, which increases resistance and loss, and a long section of wiring (eg battery switch box) is permanently live, which may increase the risk of fire of the stored machine, especially in folding the handlebars. Dirt collects around the battery, which does not look aesthetic and makes it difficult to clean the frame from grass, dust, etc. For 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 and other disadvantages and to provide improved handlebars that increase the utility value of the gardening equipment (machines) on which they are used.

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

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").

Further described is a kit comprising 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 by increasing the handlebar weight by attaching the handlebar battery, the inertia weight of the handlebar is increased and the vibration caused by the forces transmitted to the handlebar from the engine is reduced accordingly. handlebar elements.

Handlebars are any handle commonly used in the art, i.e. at least one solid structure, e.g. a straight or suitably shaped tube, attachable or resiliently fastened via at least one anti-vibration element, with its lower part on the frame, and provided with a handle (s) on its upper part for holding by the user's hands when driving / operating the gardening equipment. The handlebars may preferably be foldable and / or height and / or laterally (especially the horizontal handle pitch) adjustable. This can be achieved by rotatable / flexible elements such as detachable or locked joints.

The handlebars can be of a variety of common types, such as two handles for gripping the user's hands, where the handles have a suitable horizontal spacing and height above the ground allowing comfortable gripping / control of the machine by the user, each handle fixed to the upper (always considered in working position) of a suitable length, such as a straight or curved connecting tube, and the lower end of the connecting element is mountable to the frame. For attachment to the frame, each connecting element is provided with a suitable fastening element, which may be screws and nuts, a lockable joint, screw holes, a fixing block with bores, etc. The handle may be a suitably shaped / modified portion of the interconnecting element, wherein the modification means e.g. molded sleeve with plastic with thermally insulating or anti-vibration properties.

The handlebar interconnecting elements may be interconnected by one or more cross members, preferably horizontal. The cross-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 elements that converge symmetrically from the top end and continue from a certain point as a single interconnecting element with one bottom end mountable to the frame.

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 fastened to the frame and the upper, at least one portion of the substantially straight and horizontal middle section of the loop serving as the handlebar handle. Folding handlebars of this type may consist of two rigid open loops joined together by detachable or detent joints.

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

The anti-vibration elements may be the suspension of the handlebars at the location of the handlebar fasteners for mounting on the frame or elsewhere in the handlebars or handles, for example by metal springs and / or anti-vibration adapter pieces and / or vibration absorbing material applied to the surface and / or the cavity of the tubes. the handlebars. An example of suspension of the handlebars at the location of the fasteners for mounting on the frame is a rubber silentblock with molded fastening screws.

As a rule, the handlebars have at least one rechargeable battery attached to them in the assembled state as in the operation of the machine. The battery is of any suitable charging type, preferably of the closed (maintenance-free) type. By way of example only, and without limitation, lead (Pb), nickel-cadmium (NiCd), nickel-metal hydride (NiMH), nickel-iron (Ni-Fe), nickel-zinc (Ni-Zn), silver-zinc, lithium- ionic (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, wherein the term "starter battery" refers to a battery usable for starting the engine of a gardening engine. In other embodiments, the battery is usable to power any other electrical equipment of the gardening equipment, such as electric drive, ignition system, injection system, lighting, horn, remote control, and the like. The technical solution includes the term "batteries" one, two (for example, one on each handle, connected in series or in parallel or used independently for other purposes) or more batteries according to the particular application, capacity, voltage, dimensions and the like.

In terms of wiring interconnection, ease of assembly, protection from adverse effects and aesthetics, preferably at least one means for securing at least one battery is located near the handlebar handle (s), as in the upper half, especially in the upper quarter of the handlebar length.

The handlebars may further comprise one or more controls of the technique (such as a starter switch, e.g. in the form of a key switch, a throttle lever, a travel speed switch, a lighting switch, etc.) positioned so that the controls are conveniently reachable by the user. near the handlebar (s), preferably in the upper half, more preferably in the upper quarter of the handlebar length.

In a preferred embodiment, at least some of the controls are co-located on a common control panel located near the handlebar handle (s), preferably in the upper half, more preferably in the upper quarter of the handlebar length. More preferably, for reasons of convenience and safety, the at least one control element is located on the control panel so as to be operable by the finger (s) of the hand holding the handle. The panel may be a sheet or hollow structure made of metal, composite or plastic, preferably transverse mounted on the handlebar structure interconnecting elements.

Most preferably, at least one of the means for securing the at least one battery is located on or in the panel, for example in a hollow space for receiving the battery provided in the panel, suitably provided with a removable lid.

Hollow space means a cavity corresponding to the size and shape of the external dimensions of the battery, which may be defined by solid walls or only portions thereof, e.g. guide angles.

The batteries are preferably attached / attached replaceable. The battery is connected eg. plug-in connectors.

In the simplest case, the battery voltage is applied to the frame through the switch box by a cable routed over the surface or inside the handlebars.

In any part of the handlebars, a connector may be provided for the connection of a suitable battery charger.
