BACKGROUND OF THE INVENTION

Field of the invention

  The present invention relates to an accessory for each

  riot with movement by hand and more particularly access

  evening that turns the cart into a table.

  Description of the prior art

  The prior art includes a wide variety of

  two-wheeled and four-wheeled handcarts and carts

  by hand. Typically, these carts comprise a set of tubes comprising one or more handles allowing

  hold, push or pull the cart. They also understand

  if a base with a platform that receives loads at

  carry. Two-wheeled devils usually include-

  a pair of wheels mounted to rotate in the vicinity of the

  trolley base, while four-wheel trolleys include

  also take a pair of wheels mounted rotating next to it

swims a handful.

  The trolleys described above can be used to transport loads from one location to another. In many applications, loads require, after transportation, storage or display on tables, shelving or

  analogous supports. The carriages cannot be used as a

  positive transport and storage and exhibition

  tion. We must therefore use two different devices in

these applications.

  The table accessory of the present invention

  cooperates with a wheeled cart so that this cart

  riot to serve as a transport device as storage and display. This accessory is a

  simple and resistant structure over time which offers

  efficiency and reliability training. The accessory folds in a thin configuration, similar to a 2 plate, and deploys so as to cooperate with ends

opposite of the carriage.

STATEMENT OF THE INVENTION

  The object of the invention is, in combination with a cha-

  folding riot comprising a set of tubes comprising several

  several tubes arranged telescopically, a base comprising

  as an element forming a tilting platform and several wheels, a removable element intended to cooperate, in a manner

  removable, at a first end with the base and at an end

  opposite mite with the set of tubes, said removable element defining a flat surface which serves as the upper part of

  table when the removable element is fixed to the carriage.

  According to an embodiment of the present invention, the removable element cooperates with a carriage so

  to transform this trolley into a table. This element defines an over-

  flat face which serves as table top when

  the removable element is fixed to the carriage.

  DETAILED DESCRIPTION OF THE DRAWINGS AND OF A METHOD OF IMPLEMENTATION

ARTWORK

  Referring to the drawings, Figure 1 shows the

  folding cart K, the removable element M and the covering element

  truly C of the present invention fixed to each other so as to form a table T. The carriage K generally comprises a set of tubes 20, comprising a locking assembly 21; a handle assembly 22, comprising handles

  23 and 24 and a folding handlebar 25; a basic

  both a tilting platform support 26 disposed at one end of the tube assembly 20; and a set of wheels comprising a pair of wheels 27 and 28 rotatably mounted in the vicinity of the platform support 26 and a pair of swivel casters 29 and 30 mounted on an end portion of the tube assembly 20 which is located opposite the end with the platform 26 (see Figure 14). The cart opens in a deployed configuration in which it can be used as a two-wheel hand-cart (see Figures 11,12 and 14) or a four-wheel cart (see

  Figures 1,2 and 4). It also retracts according to a configuration

  compact position (see figure 10) for storage and trans-

  Harbor. It will be noted that the tube assembly 20 comprises two groups of tubes placed in a substantially parallel direction,

  each group comprising at least two tubes.

  The locking assembly 21 makes it possible to lock the assembly

  ble of tubes 20 in a deployed configuration and unlock the assembly of tubes 20 so that it can

  fold in a retracted configuration.

  The handlebar 25 has a practically U shape. The French patent application 9511114 filed on September 21, 1994 for "Folding and adjustable cart" provides a

  more detailed description of the carriage K. As is

  indicated above, this carriage K is arranged so that it can be deployed and so that it can be folded up in a compact configuration for storage. As a variant, a wide variety of trolleys of the prior art can cooperate with the removable element M and the covering element C so as to form the table T. The trolley variants can be trolleys with four wheels or with two wheels and it is not necessary that they be arranged so that they can be folded down, nor so that they can be deployed. Thus, for example, a two-wheeled cart with a slide support or the like at the end of the handle end can replace the carriage K used with the setting mode.

work represented in the drawings.

  In the position shown in Figures 1 and 2, the carriage K is in rolling contact with a support surface by its side comprising the wheels 27 and 28 and the swivel casters 29 and 30. The set of tubes 20 is arranged in a manner substantially parallel to the support surface, while the platform 26 and the handlebar 25 are oriented in a manner substantially perpendicular to the tube assembly 20 and to the support surface (in Figures 1 and 2 , the handlebar 25 is placed approximately 270 opposite the position shown in FIG. 14). In this position, the carriage K can receive the removable element M and the covering element C in the manner which is described below. The removable element M is a foldable arrangement of three segments 31, 32 and 33 arranged end to end and joined by hinges at 34 and 35. The segment 31 comprises a rectangular frame 36, formed of metal tubes or other similar structural elements, and a plate 37 which is welded or otherwise permanently fixed to the frame 36. The segment 31

  also includes a coating 38 for the plate 37. This coating

  is a layer of thermoplastic material or any

  what other material that can provide elastic damping

  prevent any load L placed on the table T from sliding (see Figure 1). Similarly, the segment 32 comprises a rectangular frame 39, a plate 40 and a covering 41. It will be noted that the plate-shaped segments 31, 32, 33 bend forming a stack in which these segments 31, 32 , 33 are arranged face to face opposite each other

others.

  An articulated mechanism 42 with four elements forms a bridge over the hinge connection located at 34 and ensures structural integrity of the connection. This articulated mechanism comprises bars 43 and 44, pivotally mounted at one end on the chassis

  36 respectively at 45 and 46, and a crossbar

  dirty 47 which connects the end parts of the bars 43 and 44 situated opposite the pivoting connections. These opposite end parts cooperate with the chassis 39 and

  are arranged in a sliding way with respect to this frame

  sis 39. Projecting parts (not shown) of the bars 43 and 44 extend into slots of appropriate size (not shown) formed in the frame 39, so as to ensure

  sliding type cooperation (the fourth element of the

  articulated mechanism 42 is the chassis 36).

  Segment 33 comprises a chassis comprising elements

  lateral elements 47 and 48, a transverse element 49 and bars

  o10 res 50 and 51. The lateral elements 47 and 48 are arranged pa-

  rallying to each other and at a distance from each other and

  are welded or otherwise permanently fixed to the element

  transverse ment 49 and the bars 50 and 51 are arranged in a manner practically perpendicular to the lateral elements 47 and 48. The bars 50 and 51 are located at one end of the

  lateral elements 47 and 48 and the transverse element 49 is so-

  killed on the middle part of the lateral elements. A fitting 52 and a hinge 53 connect an end portion

  of the lateral element 47 (located opposite the end com

  carrying the bars 50 and 51) to the chassis 39 of the segment 32. In a similar manner, a fitting 54 and a hinge 55 connect

  an end portion of the lateral element 48 (located opposite

  placed from the end comprising the bars 50 and 51) to the chassis 39 of the segment 32 (see FIG. 6). These two links allow segment 33 to pivot approximately 900 vis-à-vis the

segment 32.

  The lateral elements 47 and 48 and the transverse element 49 of the segment 33 have cross-sectional configurations

  U-shaped. They cooperate with bars 50 and 51 to form a lo-

  gement intended to receive a marginal part of the platform

  form 26 and therefore to fix one end of the element M to the cha-

  riot K in a removable way (bars 50 and 51 essentially define the entrance to this housing). Hooks 56 and 57, which are fixed permanently (for example welded) to the frame 36 and are oriented towards the outside with respect to the frame 36 (see

  Figures 1 and 2) engage on the handlebar 25 so that

  lesson in fixing an opposite end of the element M on the carriage K in a removable manner, as shown in FIG. 1 (FIGS. 2 and 4-7 show the different stages provided for folding the element M and remove it from the carriage K). In its operating position (Figure 1), the element M has a

  overall configuration in L and defines a superior surface

  lower S for table T. As a variant, the element M can present

  other suitable configurations depending on the shape of the carriage K. The covering element C comprises two plates 58 and 59 made of metal sheet or other suitable material, which are arranged end to end and are pivotally connected by a hinge 60 (see FIG. 8, 8A and 9). The plate 58 comprises a chassis part 61 forming a chassis 61 and a plate forming part 62, while the plate 59 comprises a

  chassis part 63 and plate part 64. Ain-

  if FIG. 8A shows it, the chassis part 63 has

  at one end an open U-shaped configuration so as to receive

  see the plate segments 65 and 66 of the base of the carriage K and to fix the covering element C to the carriage K in a removable manner. In its operating position, the cover C covers one side of the set of tubes 20 and forms a shelf for the table T (FIGS. 8 and 9 show the steps provided for folding the cover C and removing it from the carriage K and the figures 10-13 represent the element M and the covering C

  in various positions on the carriage K).

  While the above description and the drawings expo-

  feels and shows by way of illustration a given mode of implementation, it will of course be understood that the invention is not

  limited to this mode of implementation. The specialists in ma-

  to which the invention relates can make modifications

  tions and other modes of implementation using the principles of the present invention, in particular taking into account the above teachings. This is why, by

  annexed claims, the plaintiff intends to cover all

  modifications and all other modes of implementation

  which have the peculiarities constituting the elements

  essential features of the present invention.
