FR2790248A1 - Child lock for waste hopper has pair of levers which must be operated simultaneously to release lid - Google Patents

Abstract

The child lock for a waste hopper (2) with a tilting lid has a pair of levers which must be manipulated in a specific way to allow full opening of he lid. The lock holds the lid (4) in a partially open position until released. Both levers have to be operated simultaneously to open the lid fully.

Description

-1- The present invention relates to wheeled bins for the collection of

  waste, of the type comprising a tank mounted on casters and an assisted closing cover, pivotally mounted relative to the tank by means of lateral arms integral with the cover and

  articulated on the side walls of the tank.

  There is a need to improve the safety of this type of container in the event of use by children, in order in particular to avoid accidents when the lid is closed. It has thus been proposed to provide the front of the cover with a flap as shown in the international model DM / 044 354. Such a solution is satisfactory from the point of view of safety, but the flap, made up of a plurality of strips of rubber juxtaposed, does not allow to obtain all the desired tightness in position

closed cover.

  The subject of the invention is a new rolling bin for the collection of waste, comprising a tank mounted on casters and a lid- with assisted closing, pivotally mounted relative to the tank thanks to lateral arms secured to the cover and articulated on the walls. side of the tank, characterized by the fact that it includes a device for

  safety device arranged to lock the cover in an intermediate position before it

  ci does not reach its fully closed position, intermediate position in which the tank

  and the cover provide a space of a predetermined width.

  This space is advantageously sufficient to allow the passage of the head

  of a child of ten years.

  Thanks to the invention, the container in the fully closed position of the cover

  has the desired tightness while being safe to use.

  In a particular embodiment, the security device is arranged so as to require for its unlocking a specific action to be exercised simultaneously in two locations of the cover, sufficiently distant from each other

  so that a child cannot normally do this.

  Preferably, the security device is arranged in such a way that the action

  specific release must be exerted inside recesses of the cover.

  Advantageously, these recesses are provided on the front of the cover and

have handles.

  In a particular embodiment, the safety device comprises two levers -2- pivotally mounted each at one end on the cover, each lever being able to come into abutment by the other end on a bearing surface integral with a wall side of the tank to maintain the cover in said intermediate position, this bearing surface being advantageously defined by a notch made on a cheek extending the tank above. Still in a particular embodiment, the levers must be actuated

  simultaneously to allow the lid to close completely.

  The invention will be better understood on reading the detailed description which will

  follow, of a nonlimiting exemplary embodiment, and on examining the appended drawing in which: - Figure 1 is a schematic perspective view of a bin fitted with a safety device according to the invention, cover being shown in the fully closed position, - Figure 2 is a schematic front view of the tray of Figure 1, with

partial removal of the cover, -

  - Figure 3 is a schematic side view of the container of Figure 1, - Figure 4 is a partial and schematic view of the cover along a section plane perpendicular to Figure 2, the cover being shown in its intermediate position, and - Figure 5 is a schematic view, in section, along the section line VV of

Figure 4.

  The rolling bin 1 shown in Figure 1 has a tank 2 mounted on casters 3 and a cover 4 pivotally mounted relative to the tank 2 through arms

  S side articulated each around an axis X on a side wall 6 of the tank 2.

  The capacity of the tank 2 is approximately 1000 l in the example described.

  Springs not shown are interposed in a manner known per se between the side arms 5 and the side walls 6 of the tank 2 to assist the movement of

closing the cover 4.

  The latter further comprises, on the front, two recesses 10 as we

  can be seen in FIG. 1 in particular, each crossed by a handle 21.

  The recesses 10 are delimited, inside the cover 4, by a wall

  24, as shown in FIG. 4.

  The tank 2 and the cover 4 are produced in the example each described by -3-

  plastic molding but could alternatively be made of metal.

  Each of the side walls 6 of the tank is extended above, under the cover 4, by a cheek 11 produced integrally with the tank 2, as shown in

Figure 2.

  The tank 2 also includes, at the front, a flange 12, as can be seen.

see in figure 3.

  The cover 4 is provided on its front edge, as shown in FIG. 4, with a sealing lip 13 which is applied to this flange 12 in the position of

complete closure.

  The cheeks 11 are each provided on their upper edge with a notch 16,

  whose role will be explained later.

  In accordance with the invention, the container I is equipped with a safety device making it possible to block the cover 4 in an intermediate position, before it reaches

its fully closed position.

  The cover 4 cleans with the tank 2 in this intermediate position a

  space 18 of predetermined width, sufficient for the passage of the head of a child.

  The safety device comprises in the embodiment described two levers 19 having a free end 23 and each articulated at the other end 20 on the front part of the cover, near the median plane of symmetry P of the container, around an axis Y oriented substantially perpendicular to the plane of Figures 2 and 5 and parallel

in the plan of figure 4.

  The levers 19 each have a substantially straight body 30 and

  pass through the walls 24 of the recesses 10 thanks to oblong holes 26.

  The levers 19 extend inside the recesses 10 behind the

handles 21.

  The body 30 of each lever 19 is connected to the free end 23 by a

  portion 31 bent downward, as can be seen in Figure 5.

  Before mounting the cover on the tank, the holes 26 serve as a stop

bass to levers 19.

  In FIG. 4, for the sake of clarity of the drawing, only the cross section of the body 30 of the lever 19 at the cutting plane has been shown, as well as

  the end 23 in abutment in the notch 16.

  -4- During the closing movement of the cover 4, the free ends 23 of the

  levers 19 engage themselves in the notches 16 under the effect of their weight.

  The notches 16 are shaped to define bearing surfaces making it possible to maintain the cover in its intermediate position, against the return action of the springs assisting the closing movement of the cover. In an alternative embodiment not shown, springs urging the levers 19 in downward rotation are added, in order to ensure the best retention of the ends 23

in the notches 16.

  To unlock the safety device, the user must simultaneously exert upward traction on the body 30 of each lever 19 in the direction of

  arrow D in FIG. 4, in order to release the ends 23 of the notches 16.

  To exercise this traction, the user advantageously takes support on the

above the handles 21.

  There is shown in broken lines in Figure 5 the lever 19 having pivoted sufficiently upward to release the cover 4 and allow it to gain its position

of complete closure.

  The levers 19 come to bear in high abutment against the handles 21.

  The spacing between the recesses 10 is chosen so that a child cannot normally, even when extending the arms, exercise the unlocking action

  on the two levers 19 simultaneously.

  Of course, the invention is not limited to the embodiment which comes

to be described.

  The security device can in particular be modified in many ways

  without departing from the scope of the present invention.

  In particular, the levers 19 can be replaced by pull tabs mounted at

sliding on the cover.
