The frame consists of two cross struts (9) and two supports (7) connected to an axle (5), which carries the wheels. It is supported on the barrow frame (1) via two brackets (8) on the supports. The brackets can be screwed to two counter brackets (13). The frame with wheels can be folded to the front the back via a joint. At least one of the wheels has a brake.

Description

Die Erfindung betrifft eine handelsübliche einrädrige Schiebkarre.The The invention relates to a commercially available one-wheeled pushcart.

Handelsübliche Schiebkarren sind so konstruiert, dass im beladenen Zustand der Schwerpunkt der Ladung immer zwischen der Radachse und den beiden Handgriffen liegt. Es ist selbst für kräftige und geübte Benutzer auf Dauer anstrengend, eine schwer beladene Schiebkarre zu schieben, da zu der senkrecht wirkenden Kraft die Schubkraft in Bewegungsrichtung aufgebracht werden muss. Zusätzlich muss die Schiebkarre noch in der Balance gehalten werden.Commercially available pushcart are designed so that when loaded the center of gravity of the Charge always lies between the wheel axle and the two handles. It is for yourself strong and experienced User in the long run exhausting, a heavily loaded wheelbarrow to push, because the force acting perpendicular to the force must be applied in the direction of movement. In addition, must the wheelbarrow still be kept in balance.

Die Schiebkarre besteht aus einem Gestell mit der Gabel für die Radaufnahme, den Handgriffen und den beiden Stützbügeln. Auf dieses Gestell ist die Schiebkarrenwanne mit drei bis vier Verschraubungen befestigt, wobei zwei Verschraubungen in der Nähe der Stützbügel angebracht sind.The Pushcart consists of a frame with fork for wheel support, the handles and the two support bars. On this frame is the Wheelbarrow trough fixed with three to four fittings, taking two screw connections nearby the support bracket attached are.

Die Aufgabe der Erfindung ist, eine handelsübliche Schiebkarre leicht so umzugestalten, dass auch weniger kräftige und ungeübte Personen eine beladene Schiebkarre leicht bedienen können und kräftige Personen mit schwer beladenen Schiebkarren ohne Anstrengung arbeiten können.The The object of the invention is a commercial pushcart slightly so to transform that even less vigorous and inexperienced people a loaded wheelbarrow can easily handle and strong persons with heavily laden Wheelbarrows can work without effort.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass eine Achse mit zwei Stützrädern über einen Tragrahmen an den beiden hinteren Wannenverschraubungen unter die Schiebkarre geschraubt werden kann, wobei der Tragrahmen, bestehend aus einem Querträger und zwei Stützen, mit der Achse verbunden ist, wobei zwei Laschen, die an den Stützen angebracht sind, sich an dem Schubkarrenrahmen abstützen können.The The object is achieved in that an axle with two support wheels over one Support frame at the two rear tubing screw under the Push cart can be screwed, the support frame consisting from a crossbeam and two supports, connected to the axle, with two tabs attached to the supports are able to rest on the wheelbarrow frame.

Der Vorteil dieser Einrichtung als Nachrüstsatz für eine handelsübliche Schiebkarre ergibt sich durch die einfache Montage ohne eine zusätzliche mechanische Veränderung.Of the Advantage of this device as a retrofit kit for a commercial pushcart results from the simple installation without an additional mechanical Change.

Es entsteht eine dreirädrige Schiebkarre, mit der große Lasten mühelos transportiert werden können, besonders auf langen Wegstrecken und auf unebenen Steigungen.It creates a three-wheeled Wheelbarrow, with the big one Loads effortlessly can be transported especially on long routes and on uneven slopes.

Ein Ausführungsbeispiel der Erfindung wird im folgenden näher beschrieben.One embodiment The invention will be described in more detail below.

Es zeigt 1 eine handelsübliche Schiebkarre mit seinem Gestell(1), mit dem Schiebkarrenrad(2), der Schiebkarrenwanne(3) und dem darunter montiertem erfindungs-gemäßen Stützräderrahmen(4).It shows 1 a commercial wheelbarrow with its frame ( 1 ), with the wheelbarrow wheel ( 2 ), the wheelbarrow tray ( 3 ) and the inventive mounted according to the invention support wheels frame ( 4 ).

2 zeigt den Stützräderrahmen(4) als eine Schweißkonstruktion, bestehend aus der Stützräderachse(5), auf der die beiden Stützräder(6) drehbar gelagert sind, den beiden Stützen(7) mit den beiden Laschen(8) und dem quer dazu angeschweißten Querträger(9). 2 shows the support wheel frame ( 4 ) as a welded construction, consisting of the Stützradachse ( 5 ), on which the two support wheels ( 6 ) are rotatably mounted, the two supports ( 7 ) with the two tabs ( 8th ) and transversely welded thereto cross member ( 9 ).

Dieser Querträger besitzt zwei Langlöcher(10) mit dem Lochabstand der hinteren Befestigunglöcher der Schiebkarrenwanne, so dass die Toleranzen der Lochabstände der unterschiedlichen Schiebkarren ausgeglichen werden können.This cross member has two slots ( 10 ) with the hole spacing of the rear mounting holes of the wheelbarrow tray, so that the tolerances of the hole spacing of the different pushcarts can be compensated.

Zusätzlich ist dieser Querträger(9) in seiner Längsachse im Bereich der Verschraubung nach außen ballig geformt, so dass die Toleranz der Winkelneigung der unterschiedlichen Schiebkarrenwannen ausgeglichen wird und der Stützräderrahmen(4) verspannungsfrei angeschraubt werden kann.In addition, this crossbeam ( 9 ) is spherically outwardly formed in its longitudinal axis in the region of the screw connection, so that the tolerance of the angle inclination of the different wheelbarrow pans is compensated and the support wheel frame ( 4 ) can be screwed without tension.

Wird nun der Stützräderrahmen mit den Verschraubungen(11) an dem Schiebkarrenrahmen befestigt, liegen die beiden Stützlaschen (8) des angeschraubten Stützräderrahmens(4) an den beiden hinteren nach vorne geneigten Streben der Stützbügel(12) des Schiebkarrengestells(1) und stützen sich bei Belastung der senkrecht wirkenden Kraft auf die Stützräder an diesen Streben ab, so dass sich daraus eine stabile Lage des Stützräderrahmens(4) ergibt und er somit große Lasten übertragen kann.Will now the support wheels frame with the screw ( 11 ) are attached to the wheelbarrow frame, lie the two support tabs ( 8th ) of the bolted support wheel frame ( 4 ) at the two rear forwardly inclined struts of the support bracket ( 12 ) of the wheelbarrow frame ( 1 ) and are based on load of the vertically acting force on the support wheels on these struts, so that from a stable position of the support wheel frame ( 4 ) and thus he can transfer large loads.

Zusätzlich sind die beiden Laschen(8) noch mit zwei zusätzlich angeschraubten Gegenlaschen(13) an den Streben der Stützbügel(12) gesichert, so dass der Stützräderrahmen(4) noch einen zusätzlichen Halt bekommt.In addition, the two tabs ( 8th ) still with two additionally screwed counter tabs ( 13 ) on the struts of the support bracket ( 12 ), so that the support wheel frame ( 4 ) gets an additional stop.

3 zeigt die erfindungsgemäße Nachrüsteinrichtung mit einem zusätzlichen Schubbügel(14) für eine leichtere Handhabung, der in der Nähe der Handgriffe(16) des Schiebkarrengestells(1) mit zwei Schellen(15) so montiert ist, dass der Benutzer seine Kraft leichter auf die Schubkarre übertragen kann. 3 shows the retrofitting device according to the invention with an additional push bar ( 14 ) for easier handling close to the handles ( 16 ) of the wheelbarrow frame ( 1 ) with two clamps ( 15 ) is mounted so that the user can transfer his power easier on the wheelbarrow.

4 zeigt die erfindungsgemäße Nachrüsteinrichtung, wobei die beiden Stützrädern als schwenkbare Lenkrollen(17) ausgebildet sind, so dass mit der Schiebkarre zusätzlich auch Kurven leichter bewältigt werden können. 4 shows the retrofitting device according to the invention, wherein the two support wheels as swivel castors ( 17 ) are formed so that in addition also curves can be handled more easily with the pushcart.
