Abstract

Trolley characterized in that it comprises a tray (1) for supporting the goods, a pair of oblique arms (3) articulated laterally on either side of the tray and a pair of vertical arms (5) connected in an articulated manner, by their upper end, at the free end of the oblique arms (3), the plate being moreover slidably mounted on the vertical arms (5) by means of eyelets (6) to be able to take two extreme positions, to one of which, or position of use, the unfolded cart laterally has a right-angled triangle structure and for the other of which, or storage position, the folded cart has a flattened triangle structure, the vertical arms (5), the oblique arms (3) and the plate (1) being arranged in neighboring planes.

Description

"Foldable cart for the transport of goods" The cart

  the invention is characterized in that it comprises a goods support plate, a pair of oblique arms articulated laterally on either side of the plate and a pair of vertical arms connected in an articulated manner, by their upper end, to the free end of the oblique arms, the plate also being slidably mounted on the vertical arms by

  through eyelets to be able to take two posi-

  extreme positions, for one of which, or position of use, the unfolded carriage presents laterally a structure in a right triangle and for the other of which, or storage position, the folded carriage has a structure in a flattened triangle, the vertical arms , arms

  oblique and the plate being arranged in planes

  sins. According to another characteristic of the invention, the carriage comprises a handle pivotally mounted along the axis of articulation of the oblique and vertical arms, the link arms being further connected in an articulated manner

  to the handle and slidably connected to the green arms

  tical. According to another characteristic of the invention, a lock is provided for locking the vertical arms and the link arms in the position of the handle for which it is substantially perpendicular to the vertical arms. The invention is shown by way of non-limiting example in the accompanying drawings in which: - Figure 1 is a perspective view of the carriage, in the unfolded state, in its position of use, - Figure 2 is a side view of the cart

  of Figure 1, in the folded state, in its storage position

  ment, - Figure 3 is a partial view along arrow F of Figure 1, - Figure 4 is a schematic side view

  of the merchandise support tray of the fig cart-

res 1 and 2.

  The present invention therefore aims to

  the creation of a cart for transporting goods

  say and, in particular, for the transport of purchases made at merchants, this trolley being foldable under a

low volume.

  This carriage comprises a tray 1 for supporting the goods, on which a pair of arms 3, known as oblique arms, is articulated in 2. The free end of these arms

  oblique is pivotally mounted on a cross member 4 which

  also pivots the two arms 5 of a second

pair of arms called vertical arms.

  The rear edge 11 of the plate 1 is provided

  of eyelets 6 by which the plate 1 is slidably mounted

  and pivoting on the vertical arms 5.

  The lower ends of these vertical arms

  blocks 5 are provided with swivel casters 7 on the

  which come up against the eyelets 6 in position

use of the trolley.

  The articulation axis 2 of the oblique arms 3 is provided on legs 8 fixed on the underside of the plate 1 along two opposite sides so that the arms 3 are arranged laterally on either side of the plate 1.

  Following the example shown, these legs 8 sup-

  also carry the hinge pin of two rollers 9.

  The articulation axis 2 is preferably arranged on the

  legs 8 between the plate 1 and the rollers 9.

  Under the tray 1 are also provided

  slides 10 for slides 11 connected by a track

  pours 12 forming a rim. By moving the slides 10 in the slides 11, beyond the rim 1i and therefore

  arm 5, an additional support is formed for the goods

  ses which is located substantially in the plane of the plate 1.

  The two vertical arms 5 are connected to each other, in their upper region, by a plate 13 to

using legs 131.

  The cross member 4 also receives pivotally

  a handle in the shape of a U 14. Link arms 15 connect this handle 14 to the vertical arms 5. These arms

  link 15 are articulated at 15, on the handle 14 and com-

  wear at their other ends, articulated rings 16

  sliding mounted on the vertical arms 5.

  The rings 16 are provided with flanges 16, which cooperate with hooks 17 pivotally mounted at 17, on the plate 13. These hooks 17 are connected to cables 18 which pass through a guide tube 19 and which are

  connected at their free end to a control lever 20.

  When the rings 16 are engaged by their

  rim 16, with the hooks 17, the arms 15 are ver-

  rusted in high position against stops provided on

  the arms 5 (see Figures 1 and 3) and the handle 14 is dis-

  placed in a plane substantially perpendicular to the plane formed by the vertical arms 5. On the other hand, when a traction is exerted from bottom to top on the lever 20, the

  hooks 17 pivot against springs (not shown

  felt) and release the rings 16 which then slide towards

  the bottom on the arms 5 in order to bring the handle 14 sensi-

  in the plane of these arms 5 (see Figure 2).

  Similarly, when you rotate the tray 1

  around the axes 2 by lifting the rear edge 11 of the plate

  sheet in the direction of arrow F1, we bring the arms 3, the arms 5 and the plate 1 substantially in the same

  plan as shown in Figure 2, which cor-

  corresponds to the storage position of the trolley.

  On the rear face of the plate 13, is also

  hooked on the end of an elastic element 21 connected in addition to a hook 22 and passing through an eyelet

  fixed guide 23 intended to allow the clamping of step

  bags against the front face of the tray 13. In the non-use position, this hook is arranged around the axis 4.
