Definitions

  • the invention relates to a chassis for a transport trolley which can be moved by hand, in particular for a shopping trolley, with a base frame which, viewed from above, has a trapezoidal base frame and carries at least three castors, the longer parallel side of which is missing, and of its rear region and on both longitudinal sides Carriers intended for placing a basket or container strive upwards and the base frame is essentially formed by at least two wires arranged one above the other, which are welded to one another by intermediate pieces and / or by bulges located in the wires and in which the Carriers cross the wires arranged one above the other with their ends pointing downwards, so that in the rear area on the bottom wire of the base frame and on both long sides, an outward loop for receiving one castor wheel is formed on the base frame on both sides of the loops Vor ⁇ sp Rows are provided and are arranged below the loops between the base frame and the castor spacer plates, which both have a vertical opening for receiving a fastener intended for the fixation of a castor and
  • a shopping cart from the last-mentioned company is known, the wheels of which are located in the rear region of the chassis and are designed as rollers which cannot be pivoted about a vertical axis.
  • Such castors are also known under the name "fixed castors”.
  • a spacer with an H-shaped outline is welded to the head of these castors. Centrally, these spacers are equipped with an opening through which a fastener for screwing the casters onto the chassis is passed. Due to the H-shaped plan, two opposing recesses are formed, in which the downwardly directed ends of the supports and / or the intermediate pieces of the chassis engage, so that the casters are secured against rotation about a vertical axis.
  • the object of the invention is therefore to further develop a generic chassis so that those points on the base frame which are provided for fastening the two casters located in the rear area of the base frame are used both without using an electric welding process and without them parts mentioned above get along.
  • the advantage of the invention consists in that neither fastening parts nor the use of the electrowelding method are necessary for fastening the rear driving rollers designed as steering rollers. Rather, the necessary anyway spacer plates need during assembly of the castors only • adds Kne ⁇ between the base frame and the head of the driving rollers and the likewise for the attachment of the driving rolls if necessary fastening means to be fixed to them fixed on Gru ⁇ drahmen and thereby to the chassis to fasten. These measures contribute significantly to cost-effective manufacture of the chassis.
  • the invention is explained in more detail using an exemplary embodiment. 1 shows a chassis, FIG. 2 shows a spacer plate, and FIG. 3 shows in detail the type of fastening of a castor located in the rear region of the base frame.
  • the base frame 3 is designed in a known manner trapezoidal in order to be able to push transport trolleys equipped with this base frame 3 into one another in a space-saving manner.
  • the base frame 3 carries at least three casters 2, 2 ', two casters 2 in the rear area 4 and at least one castor 2 ⁇ in the front area 5 of the base frame 3 and thus of the chassis 1.
  • the base frame 3 is preferably formed from at least two wires 9, 10 arranged one above the other, which are usually welded together to form a component by rod-shaped or spherical spacers 11, the wires 9, 10 forming the wires Longitudinal sides 6 in the front area 5 of the base frame 3 are connected by at least one cross piece 7, the arrangement of which is also known and which is intended for carrying the at least one front castor 2 1 .
  • the wires 9 or 10 can be provided with curvatures in a known manner, by means of which the wires 9, 10 are resistance welded together.

  • the supports 15 can have a wide variety of useful shapes, so that It is important, however, that the downward-facing ends 16 of the carriers 15 cross the two wires 9, 10 of the base frame 3 and are connected to them by resistance welding of the base frame 3 and on its two longitudinal sides 6, an outwardly directed loop 12 is formed on the lower wire 10.
  • a downward end 16 of the carrier _.5 leads past each loop 12.
  • a rod-shaped intermediate piece 13 is provided to the right of each loop 12, each intermediate piece 13 being connected to the two wires 9, 10 by resistance welding.
  • Fig. 2 shows a spacer plate 18, as is required for the invention.
  • the spacer plate 18 punched out of flat steel has an H-shaped plan, a cylindrical opening 19 being provided centrally.
  • a recess 20 is formed on both sides of the opening 19 by the H-shaped plan.
  • the four outer corners 21 of the spacer plate 18 are rounded when viewed from above.
  • FIG. 3 shows the attachment of a castor 2 designed as a steering roller to the rear right longitudinal side 6 of the chassis 1.

  • the distance- plate 18 lies on the underside of the loop 12 and partially on the areas of the lower wire 10 leading away from the loop 12.
  • the Dista ⁇ zplatte 18 is thus supported on the base frame 3.
  • the driving roller 2 lies flat with its head 2a.
  • the spacer plate 18 is first placed on the underside of the loop 12 in such a way that the opening 19 of the spacer plate 18 is arranged centrally to the loop 12. Subsequently, the fastening means 22, in the example it is a screw with a large mushroom-shaped head 23 resting on the loop 12, with its shaft (not shown in detail) through the loop 12 and through the opening 19 of the spacer plate 18.
  • the roller 2 is placed with its head 2a flat from below on the underside of the now loosely inserted spacer plate 18, the fastening means 22 is passed through the central holding hole in the head 2a of the roller 2 and then by screwing one in the head 2a of the roller 2 introduced further fastening means, for example a hexagon nut, secured.
  • Both the spacer plate 18 and the driving roller 2 designed as a steering roller are now screwed onto the base frame 3 of the chassis 1 in a stationary manner.

Abstract

Un châssis (1) pour un chariot de transport à main porte au moins trois roulettes (2, 2') et a une forme trapézoïdale vu d'en haut, dans laquelle le côté parallèle le plus long manque. Des deux côtés de la zone postérieure (4) du châssis (1) sont disposés des supports (15) de réception d'une corbeille ou similaire. Des deux côtés de la zone postérieure (4) du châssis (1), des boucles (12) orientées vers l'extérieur sont formées dans les deux fils métalliques superposés (9, 10) qui constituent le châssis (1). Des roulettes (2) peuvent être assujetties aux boucles (12) par des plaques d'écartement (18). Des protubérances (17) situées sur le châssis (1) pénètrent dans des évidements correspondants ménagés dans les plaques d'écartement (18). Les plaques d'écartement (18) peuvent être introduites avec du jeu entre les roulettes (2) et le cadre de base (3) et peuvent être retenues en place sur le cadre de base (3) par des éléments de fixation des roulettes (2). Les roulettes (2) constituent des roulettes de roulement et de direction.
