Abstract

The barrow has, at one end, support wheels (4) on an axle (3) and at the other, smaller castor wheels (9). There is a pivot axis (12) for the handle frame (10) on the body which can fold down to reduce its size. There is a circular plate (11) on the pivot axis integral with the frame and carrying holes (14) which correspond with holes in the handle. The two sets of holes can be connected by a pin (16) to prevent pivoting of the handle. There can be supports on the frame for brakes engaging the larger wheels.

Description

L'invention concerne un nouveau type de diable formé de poutrelles carrées, de cornières, de barres de fer et de flasques. Il y a deux grandes roues à une extrémité et deux roues orientables plus petites à l'autre extrémité. Les brancards et le corps de diable sont assemblés sous un angle variable. Le diable peut servir d'échelle une fois replié et est commode à emballer et à transporter une fois plié. The invention relates to a new type of devil formed of square beams, angles, iron bars and flanges. There are two large wheels at one end and two smaller steerable wheels at the other end. The stretchers and the devil's body are assembled at a variable angle. The hand trolley can be used as a ladder when folded and is convenient to pack and transport when folded.

The structure and the operation of the hand truck according to the invention will now be described with reference to the drawings.

Comme le montre la figure 1, le diable comprend des pou- trelles carrées l et 2, des barres de fer et des plaques de fer. Un essieu 3 est prévu pour les roues. I1 peut etre assemblé par soudage ou par d'autres moyens. Deux roues 4 sont fixées pivotantes aux deux extrémités de l'essieu 3. Une plaque de fer 5 est prévue de chaque coté, fixant les roues 4 sur 1' essieu 3. As shown in Figure 1, the devil consists of square bins 1 and 2, iron bars and iron plates. An axle 3 is provided for the wheels. I1 can be assembled by welding or by other means. Two wheels 4 are pivotally attached to the two ends of the axle 3. An iron plate 5 is provided on each side, fixing the wheels 4 to the axle 3.

I1 y a deux plaques fixes 5, ivarallèles, par grande roue 4. Ces -irlatiues portent, à l'opposé, des pivots 6 sur lesquels s'articule un cavalier frein 7, sans jeu. En raison du frottement entre le cavalier frein 7 et les plaques 5 il est ncessaire de faire effort pour libérer la jante de roue.  There are two fixed plates 5, ivaralleles, by large wheel 4. These -irlatiues carry, on the opposite, pivots 6 on which a brake jumper 7 is articulated, without play. Due to the friction between the brake jumper 7 and the plates 5 it is necessary to make an effort to release the wheel rim.

Les grandes roues peuvent être bloquées à la main ou au pied ce qui empêche le diable de dévaler une pente. Le diable selon l'invention peut être utilisé en position dressée, les roues touchant le sol ; sur la poutrelle carrée 1 la plaque 8 peut servir de fond à un panier. Si on le dresse, l'extré- mité des deux poutrelles carrées 1 et les deux grandes roues 4 supportent son poids.The large wheels can be locked by hand or at the foot which prevents the devil from hitting a slope. The hand truck according to the invention can be used in the upright position, the wheels touching the ground; on the square beam 1 the plate 8 can serve as the bottom of a basket. If it is drawn up, the end of the two square beams 1 and the two large wheels 4 support its weight.

De l'autre côté, près de l'extrémité des deux poutrelles carrées 2 qui portent les deux grandes roues 4, se trouvent deux roues 9 peuvent tourner de 360". Si l'on utilise le diable en position horizontale, les deux grandes roues touchent le sol pour supporter son poids et on peut changer facilement sa direction. On the other side, near the end of the two square beams 2 which carry the two large wheels 4, there are two wheels 9 can rotate 360 ". If the hand truck is used in a horizontal position, the two large wheels touch the ground to support its weight and you can easily change its direction.

Deux brancards 10 sont reliés au corps du diable et sont reliés à l'axe 12 par une plaque circulaire lu fixée à l'ex trémité des poutrelles carrées 2 (corps du diable) par deux goujons filetés 13. La fonction des trous ronds 14 prévus sur le pourtour de la plaque circulaire sera expliquée plus loin. Two stretchers 10 are connected to the body of the devil and are connected to the axis 12 by a circular plate read fixed to the end of the square beams 2 (body of the devil) by two threaded studs 13. The function of the round holes 14 provided around the circumference of the circular plate will be explained later.

De part et d'autre du fond, les deux brancards 10 présentent un petit trou pour les verrouiller à l'axe 12 de manière à pouvoir tourner seulement un peu. On peut régler l'angle entre les brancards 10 et le corps de diable. Quand le trou rond du brancards vient en face du trou 15 de la plaque circulaire 11, une broche 16 s'insère à travers deux trous (voir figure 2) ; elle présente une extrémité coudée 21 et à l'autre extrémité se trouve une articulation 22 sur laquelle peut tourner la tête du goujon 23 qui s'insère dans la gorge en U 24 entre les deux extrémités de la broche 16 (une extrémité étant encore mobile) et fixe celle-ci.L'angle (la position) entre les brancards 10 et le corps du diable peuvent être réglés selon la conformation physique de l'opérateur, ce qui est commode pour économiser l'énergie lorsqu'on l'utilise pour monter des rampes ou sur un terrain en pente.On either side of the bottom, the two stretchers 10 have a small hole to lock them to the axis 12 so that they can rotate only a little. You can adjust the angle between the stretchers 10 and the devil body. When the round hole of the stretchers comes opposite the hole 15 of the circular plate 11, a pin 16 is inserted through two holes (see Figure 2); it has a bent end 21 and at the other end is a hinge 22 on which the head of the stud 23 can rotate which is inserted in the U-shaped groove 24 between the two ends of the spindle 16 (one end being still mobile ) and fixed it.The angle (position) between the stretchers 10 and the body of the devil can be adjusted according to the physical conformation of the operator, which is convenient to save energy when used for climbing ramps or on sloping ground.

Les brancards 10 sont munis de plusieurs cornières 17 formant des échelons, deux poignées 18 sont fixées à l'extré- mité des brancards 10 et sont démontables, ce qui est commode pour que l'opérateur pousse ou tire le diable. Cependant, si l'on veut l'utiliser comme échelle basse, il suffit de régler la tête du brancard 10 d'un côté du diable 4 (après avoir dé monté les poignées). On peut l'utiliser comme échelle basse pour cueillir des fruits ou couper des feuilles ou des branches d'arbres etc. On peut régler les brancards 10 sous l'angle approprié, l'extrémité des brancards étant proche du corps du diable raccourci (par exemple plié ). Cela est commode pour l'emballage ou le transport (comme d'autres objets). The stretchers 10 are provided with several angles 17 forming steps, two handles 18 are fixed at the end of the stretchers 10 and are removable, which is convenient for the operator to push or pull the hand truck. However, if you want to use it as a low ladder, you just have to adjust the head of the stretcher 10 on one side of the devil 4 (after removing the handles). It can be used as a low ladder to pick fruit or cut leaves or tree branches etc. The stretchers 10 can be adjusted at the appropriate angle, the end of the stretchers being close to the body of the shortened devil (for example folded). This is convenient for packaging or transport (like other objects).

L'invention peut aussi servir d'autres façons lorsqu' il est dressé . On utilise une potence de filet 19 au dessus de la plaque 8 fixée aux poutrelles carrées 1 et on accroche l'autre coté du filet, on place une autre plaque 20 (qui est amovible) de manière à tendre le filet parallèle au fond, puis on place des récipients et des bouteilles sur la plaque 8. On peut effectuer le transport.  The invention can also be used in other ways when it is drawn up. We use a net bracket 19 above the plate 8 fixed to the square beams 1 and hang the other side of the net, place another plate 20 (which is removable) so as to stretch the net parallel to the bottom, then containers and bottles are placed on the plate 8. Transport can be carried out.
