FR2741050A1 - COLLECTION CONTAINER, FOR EXAMPLE OF WASTE, WITH MEANS OF BRAKING THE CLOSURE OF THE LID - Google Patents

Abstract

The rubbish bin (1) comprises a collection tank (2) and cover (6) which can be displaced between open and closed positions. The cover is hinged (9) to the tank. The bin cover has a resistance for braking (11) during its passage from open to closed positions. This brake comprises a deformable elastic spring (12) fixed to the tank and to the cover. One end of the spring forming a rectilinear part is housed in an opening in the tank and its other end has a horizontally projecting support zone at right angles to an upper peripheral edge (5) of the tank. The spring projecting part is supported on a cover contact surface at a radial distance from the hinge axis (X). The spring is active during cover closing until it is almost closed and is inactive during the rest of cover travel.

Description

The invention relates to a container provided with means for braking the closure.

  its cover, for example intended for the collection of waste. Many collection bins, and in particular those with large volumes, include a tank and a cover

shutter of the tank.

  Generally, the cover is pivotally mounted around an axis extended horizontally, in the usual position.

use of the tank.

  Known collection bins have drawbacks. The weight of such covers is all the more important as the capacity of the container increases. And their closing under the effect of gravity is rapid, even brutal. This results, on the one hand, from noise pollution, undesirable especially in inhabited areas. These nuisances do not

  must not exceed the legally prescribed limits.

  On the other hand, bodily accidents frequently occur during closure, both among private and professional users of

collection.

  These are mainly pinched fingers

  or the user's hand closing the cover.

  The invention aims to solve these drawbacks in particular. An object of the invention is a collection tank comprising: a collection tank; a cover movable between an open state of access to the interior of the tank and a closed state of substantially hermetic closure of the tank; as well as a pivoting articulation which connects the cover to the tank and whose axis is generally extended horizontally, when the tank is in a position of use. In this tank, there are provided means for braking the cover during the transition from its open state to its closed state, these braking means comprising at least one elastically deformable member, capable of being integral with one part of the tank and of other part of the cover, and for example two members spaced from each other along the axis of articulation. One characteristic provides that the braking means are arranged so as to be active at the end of the cover closing stroke until it is close to or closed, while they are deactivated on the rest of the cover stroke, so

that its pivoting is then free.

  Alternatively, the braking means are

  constantly active, between open and closed states.

  According to one embodiment, the elastically deformable member comprises at least one spring, for example metallic, one end of which is rigidly fixed to the tank, while its other end is provided with a support zone intended to cooperate with a contact surface of the cover, the support area being provided at a distance

  radially from the axis of the joint.

  According to another embodiment, the elastically deformable member comprises at least one spring, for example metallic, one end of which is rigidly fixed to the cover, while its other end is provided with a support zone intended to cooperate with a tank contact surface, spaced radially from the axis

of the joint.

  In one example, the support area of the organ

  elastically deformable is in the form of a loop.

  According to one characteristic, the support zone projects, for example substantially horizontally or with an angle of the order of 5 to 15 relative to the horizontal in the open state of the cover, in line with a portion superior of the

  tank, such as a peripheral edge.

  In one example, the support zone projects, for example substantially vertically or with an angle of the order of 5 to 15 relative to the vertical in the open state of the cover, in line with an upper part of the

  tank, such as a peripheral edge.

  According to one characteristic, the elastically deformable member comprises at least one part for anchoring to the tank, such as a turn, mounted around the axis of articulation. According to another characteristic, the deformable member comprises at least one angular positioning part, such as a straight part, housed in a

  orifice of the tank and / or the cover.

  The invention is now described in detail, and with reference to the accompanying drawings. Figure 1 is a perspective view of a collection bin according to an embodiment of the invention, with its cover in an intermediate state before closing (in solid lines), and in the fully open state

(in broken lines).

  And Figure 7 is a partial front view and

  according to arrow VII, of the spring of FIG. 6.

  The reference numeral 1 designates in Figures 1 to 5, a collection bin. Here, tray 1 is made of high density polyethylene (HDPE). But it can for example be made of metal, at least in part. In FIG. 1, the tank 1 rests in a usual position of use, on a reference plane P. It

for example the soil.

  Here, the plane P is substantially horizontal. The

  description of the invention is made by considering the tank

  1 or its constituents in this position.

  The terms "lower" and "upper" are defined by considering this position. They respectively designate a location close and relatively distant from the plane P,

perpendicular to the latter.

  Similarly, the terms "horizontal" and "vertical" refer to parallel orientations and

  perpendicular to the plane P, respectively.

  It is however specified that the tank 1 or its constituents can take various positions in space, different from those of the examples, in particular

during use.

  In the examples, it is a collection bin 1

of waste.

  But the tray 1 can have other destinations or uses, without departing from the scope of the invention. For example, tray 1 can be used in the food industry. The tank 1 includes a tank 2, which delimits a

  useful interior loading volume 3.

  The purpose of this useful volume 3 is to collect

  waste, for which it therefore forms a container.

  The useful volume 3 is here substantially shaped

  prismatic with horizontal rectangular base.

  Its collection capacity is of the order of one to several hundred liters, for example from 100 to 1,000

  liters. Tray 1 is said to be "high capacity".

  The volume 3 opens outwardly from the tank 2, at an opening 4. It is through the opening 4 that the

loading of waste.

  Here, the opening 4 is located at an upper face of the tank 2. It is delimited by an upper edge 5 of

tank 2.

  The edge 5 is extended substantially parallel to the

  plane P, over the entire periphery of the tank 2.

  In Figure 1 the reference 7 designates wheels, here four in number. They are mounted on the tank 2,

  near its lower horizontal face.

  The wheels 7 allow movement by rolling of the tank 1 on the reference plane P. They are in this

directional examples.

  Also, the tank 1 comprises a cover 6. The cover 6 is articulated on the tank 2, so as to be movable as indicated by the arrow D on

Figures 1 and 5.

  By acting, in one direction or the other, according to arrow D on the cover 6, the latter is moved between a state known as completely open (in broken lines on the

  Figure 1), and a so-called closed state (not shown).

  In the open state, the cover 6 releases the opening 4 to allow loading of the volume 3. The cover 6

is then substantially vertical.

  In the closed state, the upper opening 4 is covered. And the volume 3 is closed off substantially hermetically by the cover 6. The latter is then in abutment against the upper edge 5, generally horizontally. The reference 8 designates damping pads, interposed between the cover 6 and the edge 5, in the state

closed.

  The studs 8 are here made of relatively flexible material such as rubber, and are rigidly fixed on the edge

  upper 5, opposite the cover 6.

  The pads 8 have the function of dampening the noise nuisance due to the coming into contact with the tank 2 of the cover 6, when the latter has reached its closed state. So the pads 8 do not act on the displacement

D of cover 6.

  But they define its closed state, while absorbing part of the noise pollution caused by

  the arrival of the cover in this state.

  The reference numeral 9 designates an articulation

  swivel which connects the cover 6 to the tank 2.

  The articulation 9 is generally extended parallel to the horizontal, and defines an axis of rotation X. This axis X also defines a direction

cross section of tank 1.

  The axis X is arranged here near the upper edge 5, along a wall 10 called rear of the tank 2. The wall 10 is here extended substantially to the

  vertical, in the transverse direction (X) of tank 1.

  The tank 1 comprises braking means 11.

  These braking means 11 have the function of acting on the cover 6 during (and therefore during) its passage from

the open state to its closed state.

  More particularly, the braking means 11

  meet the following functionality.

  They allow significant and sufficient braking of the fall of the cover 6 when it is closed. In fact, they reduce noise pollution

  caused by the arrival in the closed position of the cover 6.

  And they limit the violence with which the cover may strike a member of a user who is inadvertently between the edge 5 and the

  cover 6, when the latter is closed.

  They do not oppose the complete obturation, substantially hermetic and under the effect of gravity,

the tank 2 by the cover 6.

  This in order to confine in volume 3, the waste

  collected and / or odor nuisance, for example.

  This filling must be maintained, under normal conditions of use and except in the case

  voluntary opening, after closing the cover 6.

  Thus, the means 11 must not cause the unintentional opening of the tank 1, in particular during its storage and handling, for example on the wheels 7. Also, the braking means 11 must not hinder the complete opening of cover 6, by a

  rotation D, here substantially 3/4 of a turn (270 degrees).

  They must also not hinder the maintenance of the cover 6 vertically when it is fully open (Figure 1) against the outside of the rear wall 10

of the tank 2.

  It is also desirable that the means 11 occupy a reduced bulk, and do not annoy the users

from tray 1.

  For the foregoing, the braking means 11 are generally placed without them projecting

outside of tray 1.

  This also makes it possible to limit the accessibility to these means 11, the risk of hooking of collected objects, as well as the possible injuries (scratches, for example) of users (and therefore to guarantee their safety). In FIG. 1, the means 11 are mounted on the tank 1, between handles 13 for handling the tank 1 and a part of the joint 9 secured to the cover 6, in order to further limit the risks of loss or untimely dismantling . It follows from the above that the means of

  braking 11 are functionally different from pads 8.

  It is also understood that the action of the pads 8 and means 11 is complementary, against noise pollution. Generally, the braking means 11

  comprise at least one elastically deformable member 12.

  The expression "elastically deformable" means that the member 12 is capable of following at least in part, the relative displacement D of the cover 6 and of the tank 2, by opposing this displacement D a force proportional to its

  deformation in the elastic domain.

  And stalled without opening the cover 6,

once closed.

  In an example not shown, a tank 1 is provided with two members 12, spaced from one another along the axis X of articulation. This makes it possible to distribute the effects of the braking means 11 over the length of the axis X. So that the members 12 do not project transversely towards the outside of the tank 1, they are in the examples, arranged at a distance from the ends of the axis

X, as in Figure 5.

  Each member 12 mounted on a tank 1 is capable of being secured on the one hand to the tank 2 and on the other hand to the

cover 2.

  It can be provided that the braking means 11 are

  constantly active, between open and closed states.

  But in the examples, the braking means 11 are arranged so as to be active at the end of the travel

  closing of the cover 6 until close to the closed state.

  Here they are active until this state.

  On the other hand, the means 11 are deactivated over the rest of the travel of the cover 6, so that its

pivoting is then free.

  The elastically deformable members 12 illustrated comprise at least one spring, metallic in the

examples.

  In Figures 2 to 4, one end 14 of the spring

  of the member 12 is rigidly fixed to the tank 2.

  While its other end 15 is provided with a support zone 16, intended to cooperate with a surface of

cover contact 6.

  In FIG. 1, the contact surface 17 is arranged on the cover 6, on its so-called internal face in

  sight with the useful volume 3, in the closed state.

  Generally, the support zone 16, and therefore the contact surface 17, are arranged at a distance radially

of the X axis of the joint 9.

  This provides a chosen lever arm, and depending on the stiffness of the member 12, an effect

  predetermined means 11 on the cover 6.

  In FIGS. 2 to 7, the member 12 of the braking means 11 comprises a stainless steel wire, of the type

  "piano string", with a diameter of about 4mm.

  In the example of FIGS. 2 to 5, the wire forming

the member 12 is folded and rolled up.

  It thus defines a general form of inverted "U", as visible in the vetical plane parallel to

the X axis, in Figure 3.

  This member 12 comprises: - Two straight parts 18, perpendicular to the axis X and substantially vertical, here 100 mm approx. long

(for fixing on tank 2).

  - Two turns 19, distant along the X axis, over approximately one and a half turns each (to promote the elastic braking deformation of the cover 6). the turns 19 are extended perpendicular to the axis X. - A horizontal straight part (about 75mm) between the two turns 19, which forms with two connecting sections 20 the support zone 16, also in the shape of a "U"

(figure 4).

  The weight of the wire is here of the order of 25 grams.

  The mechanical characteristics of the member 12 are calculated to give the means 11 a robustness guaranteeing their effectiveness of use for several

  years, under the usual conditions.

  Note in Figure 2 that in a plane perpendicular to the axis X, the support area 16 is extended at an angle A, of the order of 5 to 15 relative to the horizontal. In fact, the zone 16 is extended from the outside towards the inside of the tank 1, from the turns 19 towards the inside

  of volume 3, and towards the lower part of tray 1.

  The angle A makes it possible to determine the sector of action of the means 11, here the sector of the displacement D during which the cover 6 is stressed by means 11 during

the closure.

  According to the embodiment of Figures 6 and 7, the means 11 do not include a single, but two the elastically deformable member 12, such as that which

is illustrated.

  In this example, the members 12 are mounted at a distance along the axis X, from one another and from the transverse ends of the edge 5, and close to

the joint 9.

  In general, each of the organs 12 to one

  structure comparable to that of the member in FIGS. 2 to 4.

  So similar structures are denoted by

the same references.

  Here, the bearing zone 16 of the elastically deformable member 12 is in the form of a loop substantially

  circular, as shown in figure 7.

  And the support zone 16 projects substantially with respect to the vertical with an angle B of the order of 5 to, in the open state of the cover 6, to the right of the edge

upper device 5.

  The action sector of the member 12 of FIGS. 6 and 7 is therefore greater than that of the example of FIGS. 2 to 4. A dimension C of the straight part 18 or straight rod defining the end 14, is here of around 70mm. On the tank 1, this part 18 is substantially vertical. As in the previous examples, the coil 19 is centered on the axis X. Its internal diameter R is

around 15mm.

  The right part 18 is connected to the turn 19 by a

section 21.

  The section 21 forms an angle F of the order of 12 relative to the horizontal, in a plane perpendicular to

the X axis (Figure 6).

  While the connecting section 20 between the turn 19 and the zone 16, forms an angle G of the order of 50 by

compared to the vertical.

  The sections 20 and 21 are therefore extended here

  approximately 22 from each other.

  The maximum horizontal dimension H of the member 12

  of Figure 6, is of the order of 45mm.

  In FIG. 7, the diameter J of the loop of the

area 16 is around 22mm.

  And the maximum distance K vertically, between the

  zone 16 and the X axis is around 58mm.

  In FIG. 5, a member 12 in the form of a metal spring is mounted on the tank 1 so that its end

  14 is rigidly fixed to the cover 6.

  While its other end 15 is provided with a support zone 16 intended to cooperate with a contact surface 17 of the tank 2, formed at a distance radially from

the X axis of the joint 9.

  In this example, the member 12 follows the cover 6 freely, until the zone 16 abuts against the surface 17, here a vertical part of the handle 13 of

tank 2.

  Then the member 12 is elastically deformed, to oppose a predetermined resistance at the end of the travel

closing the cover 6.

  As for the previous examples, this deformation causes an angular approximation of the ends 14 and 15 around the axis X, towards the inside of the

tray 1.

  The elastically deformable member 12 comprises in

  the examples at least one anchoring part on the tank 1.

  This is the turn 19, which is mounted around the axis X of the joint 9. This makes the means 11

unintentionally unmountable.

  Also, the deformable member 12 comprises in the examples of Figures 2, 3, 4, 6 and 7, at least one angular positioning part. It is the rectilinear part 18, which is housed in an orifice 22 of the tank

2.

  In FIG. 5, the part comprising the end 14 is housed in an orifice (not shown) in the cover 6. In general, the invention includes all solutions for slowing down the fall of the cover comprising one or more deformable members

elastically similar.
