Description

sheath and the support surface of the pad (15) of the crosspiece (3a).

  The invention relates to a device for collecting droppings, in particular canines. Wile applies more particularly to manual collection of droppings. In the context of the invention, the term "dejections" should be understood in its most general sense. It relates more particularly to dog excrement in an urban environment, but also to excrement produced by other animals or, more generally, waste or similar material that can be collected on the ground: pavements, sidewalks, etc. To fix the ideas, without this being limiting in anything of its scope, we will focus on the following in the context of ['preferred application

  of the invention, namely the collection of dog excrement in an urban environment.

  We know that in large cities, the deposits of such droppings represent significant quantities of matter, which very quickly amount to tonnes. In addition to the unsightly appearance, these wastes can have harmful aspects: hygiene problems, etc. Also, the city councilors of the big cities had to provide collection services and put in place a specific regulation obliging the owners of the animals to collect their excrement, hardly

fine for example.

  In the state of the art, with regard to the first hypothesis, several solutions are known which range from manual collection by specialized services, for example road collection or household waste collection, to assisted collection by motorized engines. In all the

  these solutions are heavy and expensive.

  Still in the state of the art, with regard to the second hypothesis, owners are reduced to trying to force their animals to leave their excrement in places provided for this purpose: gutters, etc., which is not always the case. possible, or to collect the aforementioned excrement with the aid of "makeshift" means or, at best, of suitable bags, bought in commerce or supplied by public services: municipalities, etc. It is clear that this solution entails reduced costs for the community. However, it is not free from disadvantages. There is in particular the problem of transport after filling the bag with the droppings collected before being able to sten dispose of it in an appropriate place: trash, etc. In addition, especially for older staff, it is sometimes difficult to bend down to collect, in any case uncomfortable. The invention aims to overcome the drawbacks of devices of the art

  known, and some of which have just been recalled.

  The object of the invention is to set up a device for collecting faeces, in particular of canine origin, of simple use, inexpensive, allowing the transport of the abovementioned faeces without risk of getting dirty and allowing

  also to get rid of it, without the risk of getting dirty either.

  To do this, according to a first important characteristic, the device according to the invention comprises a lower organ for collecting excrement itself comprising a fixed part and a part movable relative to the first, and capable of assuming two states: a so-called state "closed", or "rest" state, and a state called "open", or "operational" state, allowing the collection of the waste to be picked up. The assembly is provided with a vertical handle or a similar member which allows it to be manipulated at arm's length. This handle is integral, at one of its ends, with the fixed cited part of the lower member. A mechanism operable by the hand of a user, from the free end of the handle, makes it possible to set relative movements to the two

  parts, fixed and mobile, to bring them to one or other of the two aforementioned states.

  When the device is in the open state, it suffices for the user to place the lower member on the dejection to be picked up, to "swallow" it and to bring the device back to the closed state. To do this, he uses the handle to bring the device to the open state above this dejection, and places it on the ground,

  fa, con that the dejection penetrates inside the device.

  According to another important characteristic of the invention, a bag is partially introduced inside the lower member. The open end of the bag is arranged so that it protrudes from the outside of the bag. Wile is i 3 folded over the outer walls of the lower member and is secured by means of temporary fixing means: self-adhesive fabric, adhesive, etc. so, more precisely, when the device is in the open state, it also forces the precise bag into a similar state. Therefore, when the device is placed on the dejection to be picked up, the latter penetrates inside the bag. When the device is brought back to the closed state, the edge of the bag is piece and it closes on the dejection and traps it. It can therefore be transported without risk of getting dirty. To get rid of it, it is enough to open the lower part again, by actuating the opening / closing control mechanism, for example above a container provided for this purpose: trash can, etc. Preferably, the bag is closed beforehand: the end leaving the knotted, tied, etc. device. The mechanism actuating the two parts of the lower member can be of the purely mechanical type (that is to say manually controlled), t5 include a motorization or even be of the mixed type, as will be shown below. Each of these types can in turn be produced according to

several variants.

  The device for collecting droppings according to the invention is also capable of being produced according to several modes. In what follows trots

  main configurations will be described.

  The main object of the invention is therefore a device for collecting faeces, in particular of canine origin, characterized in that it comprises a body for collecting faeces, from below, such as carrying a first piece forming an enclosure, fixed city, subject to gripping means z5 allowing manipulation to said device by a user, and a second hollow part, mobile city, introduced at least partially into said first part and which can be animated with relative movements relative to the latter , so that said lower member can take a first state known as closed and a second state known as open, in that said open state allows the introduction of said dejections inside said moving part via an opening facing towards a support of these droppings and said closed state allows temporary retention inside said movable piece of said droppings, and l in that it comprises drive and control means of said moving part. action na bles by led it user, resulting in a positio nment

  at will in either of these states.

  As indicated in the following, without limiting in any way the scope, we will place ourselves below within the framework of the preferred application of the invention, unless otherwise stated, that is to say in the case a device

o collection of dog excrement.

  We will now describe a first example of a device for collecting dog excrement according to a first embodiment by reference to FIGS. 1A to 1H. This first embodiment will be described, by way of nonlimiting example, according to two variants with regard to the drive mechanism. In these figures, identical elements have the same references

  and will only be re-described in tent as necessary.

  In accordance with this first embodiment, the two parts, fixed and mobile, of the lower member 2 of the device 1, hereinafter simply called "device" for the sake of simplification, comprise a receiving enclosure 20, open at one end 200, which will be called "front", and a drawer 21, the open part of which is rotated towards the teas, that is to say towards the ground S. FIG. 1E more particularly illustrates the configuration of the drawer 21, in space, seen from below. It comprises a solid upper wall 210, two lateral walls, 211 and 212, and a bottom 213, which is extended by an edge 214 folded at 90, arranged between the two lateral walls, 211 and 212. In reality, the cited wall of bottom 213 and its rim 214 wind arranged at the front of the member 2, since the bottom wall 213 is turned towards the outside, so there is

close enclosure 20.

  Figure 1 B. seen in space (side trots quarter) and partially broken away, illustrates the arrangement of the drawer 21 in the open enclosure 20. It can slide in translation between two extreme positions, quoted "closed "I (or state called" rest ") and" open "II (or state said" operational "), the drawer 21 being

  partially out of its housing (enclosure 20) in the latter state.

  According to an advantageous characteristic of the invention, there is provided a drive mechanism 4 (FIG. 1B) allowing the drawer 21 to be positioned at will in one or the other of the two aforementioned states, I or 11. This mechanism 4 may be of a pure mechanical type (i.e. manual operation), of a

  motorized type or a mixed type.

  In the example shown in Figure 1 B. it is a mechanism of the first type. It comprises one or more springs, in the example described two 0 springs, 40 and 41, fixed by one of their ends on the bottom wall 200 of the enclosure 20 and exerting, ant a thrust, forces f, and f2, on the slide 21, for example on the bottom wall 213 (FIG. 1 E), by their other ends. These forces, f, and f2, tend to push the drawer 20 and position it in the state

open 11.

  The drive mechanism 4 is advantageously controlled by a control member arranged on the upper end of a gripping member 3 (Figure 1A). In the example described, it is a vertical handle 3 provided with a handle 30. This handle 3 is held by hand M by a user U. In this way, con, he can control the opening of the drawer 21 and easily position this opening above a dj dj to pick up on the ground S.

without having to bend down.

  To fix the ideas, in a practical embodiment, the handle 3 has a length typically between 70 and 80 cm. It can be fixed,

telescopic or foldable.

  The control member 5 of the drive mechanism 4 will now be described with reference to Figures 1C and 1D. FIG. 1C illustrates the handle 30 in space, in view of high quarter-quarters, and FIG. 1 D illustrates

  this same handle 30 in side view and in longitudinal section.

  The handle 30 comprises a knob 31 forming the end of the handle 3. A circular ring 50 is threaded on the handle 3 and the end thereof has at least one longitudinal slot 32. The ring is provided with a finger 51 inserted into the slot and capable of done slide in translation along the slot 32. This finger 51 entrainé a cable or rope 52 by a first end, itself driving the drawer 20 (to which it is subject at its second end), via a reference, for example a pulley 40 secured to the bottom wall of the enclosure. Fa, con advantageous, the cable 52 runs inside the handle 3 that lton assumed hollow. One or more pawls 53 are also provided: two in the example described, arranged symmetrically (at 180) in an upper zone of the slot 32. These pawls 53 are pushed towards the outside by

  through, for example, leaf springs 54.

  FIG. 1D illustrates the two positions that the ring can take, and which are associated with the rest state I (drawer 20 closed), in dotted lines: reference

  ', and in the operational state (drawer 20 open), in solid lines: reference 50.

  In the first position, the ring 50 ′, although the springs 40 and 41 (FIG. 1B) exert a restoring force thereon, via the cable 52, is locked in

high position by the pawls 53.

  If the user U pushes on the pawls 53 or exerts a sufficient pressure force on the ring 50, the latter loosens and is entrained towards the teas. The drawer 21, entrane itself by the springs 40 and 41 (Figure 1B) partially out of its enclosure 20 (state 11). To close it, it suffices that the user U (FIG. 1A) grips the ring 50 from below using, for example, two fingers, dg, and dg2, with his hand M (FIG. 1A), while pushing on the knob 31, for example with the help of his thumb Po. He exerts a force F directed upwards from the handle 3 which drives the ring 50 in translation until it clicks again (FIG. 1D: position 50 ') on the pawls 53 and locks in position 1. The drawer 21 is closed again, driven by the cable 52, and the springs, 40 and 41, compresses, press to push the drawer 21 back if it is unlocked again the ring 50. The length of the slot 32 is determined in such a way as to allow sufficient movement of the

  drawer between closed I and open positions 11.

  Advantageously, the dungs dj (FIG. 1A) are not collected directly in the drawer 21 but in a bag 6 provided for this purpose. It is generally a waterproof bag 6 made of flexible plastic. As shown in FIGS. 1F and 1G, the bottom 60 of the bag 6 is threaded inside the member 2, more precisely inside the drawer 21 (FIG. 1B). The open edge 51 of the bag 5 comes out of the drawer 21 over a length such that it can be turned up and folded over the enclosure 20. Temporary fixing means 62 are provided to secure it around the enclosure 2: self-adhesive fabric , adhesive, etc. (see Figure 1 F), fixing means which can be advantageously integrated into the bag. Figure 1G shows the bag 6 out of the

drawer 21 (Figure 1 B).

  The introduction of the bottom 60 of the bag 6 into the drawer 21 (FIG. 1B) is carried out when the drawer is positioned in the open state 11 (FIG. 1B). This operation carried out, the bag 6 is part between the bottom 213 (FIG. 1E) and the rim 214 of the drawer 21, on the one hand, and the lower wall 201 (FIG. 1B) of the enclosure,

on the other hand.

  This interesting characteristic makes it possible to enclose, in a hermetic manner, the droppings dj (FIG. 1A) once they have been collected on the ground S and the drawer 21 (FIG. 1B) closes. Wiles can then be transported such queues (inside the lower part 2) until the user U can get rid of them. It is then sufficient to reopen the drawer 21 by acting on the control member 5. Previously, it is advantageous to take the precaution of closing the bag 6, by tying the end 61 which emerges from the drawer 21

  or close it using temporary fasteners 62.

  We can naturally repeat the collection operation several times

before disposing of the bag 6.

  The control and mechanical drive system is naturally capable of several modes of execution without departing from the scope of the invention. One can in particular replace the cable 52 (FIG. 1B) by a rigid rod which would act on the slide 21 by the intermediary of a return member, for example of the cam type. These execution variants are within the range of

the man of the trade.

  We can also fully or partially motorize the

drive mechanism.

  FIG. 1H schematically illustrates an example of such a motorized mechanism 7, which will be called of the mixed type, since one or more springs have been kept, for example the spring 40 ′, to cause the closing of the drawer 21

(Figure 1B).

  s In this embodiment, the slide 21 (FIG. 1B) is driven in translation by means of a rack 75 which is subject to it. A small electric motor 74, direct current, coupled to a gear 76, drives the

  rack 75 when supplied with electric current.

  So, preferably, the motor 74 directly controls only the opening of the drawer 21. The closing of the latter, state 1, is obtained by means of one or more springs, for example the reference spring now 40 ', which exerts a restoring force f, (unlike the springs 40 and 41 of FIG. 1B which exert thrust forces: f, and f2j. This arrangement is advantageous because, in the rest state (state l: rack in dotted lines and referenced 75 ′), it is not necessary to permanently power the motor 74 in order to obtain a stable closure of the drawer 21 (FIG. 1 B). As soon as the motor 74 is no longer supplied with current , the spring, due to the force of

  reminder t ', brings the drawer 21 (Figure 1B) to the closed state 1.

  The electrical energy required for the motor 74 is supplied by one or more batteries 71, or, more generally, a source of electrical energy: rechargeable batteries (only one in the example), advantageously arranged in a housing 300 housed in the upper part 30 of the handle 3. In this case, the knob 31 can be unscrewed, which makes it possible to replace the batteries 71 when they have been used (or in the case of removing and recharging the batteries). The housing 300 comprises two contact blades, 72 and 73, with the opposite poles of the batteries 71 (arranged in eerie, if there are several), extended by conductors, 720 and 730 respectively, for supplying the motor 74 There is on the route of one of the conductors, for example the conductor 730, a switch 77, operable from the outside by a push button 770, acting on a leaf spring 772, so as to establish a galvanic contact intermittent with a

  second blade 771 connected to the conductor 730.

  When the user U (FIG. 1A) presses the push button 77, which is within immediate reach of his hand M, he causes the supply of electrical energy to the motor 74 and, therefore, the opening of the drawer 21 ( Figure 1 B) by the

  rotation of the gear 76, which in turn drives the rack 75.

  As before, the motorized control and drive system which has just been described with reference to FIG. 1H, is naturally

  susceptible of several modes of execution without departing from the scope of the invention.

  One could in particular replace the rack with a system of cams. The motor 74 could also cause the opening of the drawer directly and its closing. All these variations of execution are within the reach of man.

business.

  The procedure for collecting dj excretions (Figure 1A) remains strictly identical to that which was previously described and there is no need to explain it.

re-describe again.

  As has been indicated, the device according to the invention as a whole is capable of being produced according to several variant embodiments, in particular, as will be shown, with regard to the lower collecting member

properly quoted.

  An example of a second embodiment of the device according to the invention, reference 1 ', will now be described with reference to FIGS. 2A to 2C. In these figures, identical elements have the same references and

  will only be re-described in tent if necessary.

  The lower body, now reference 8, comprises, as before, two parts: one fixed, 80, assudetted to the handle 3, the other, 81, movable relative to the first 80. However, unlike the first embodiment, if the first part, 80, forms an enclosure for the second, 81, the latter does not take the form of a drawer opening by a translational movement. Wile is provided with a rotational movement around a shaft axis 807, with a horizontal axis A ,, arranged in the upper part of

Enclosure 80.

  FIG. 2B represents a bottom view of the enclosure 80. This comprises a vertical rear wall 800, a horizontal top wall 808 (FIG. 2A) to which the handle 3 is fixed, a vertical bottom wall 800, two lateral walls, comprising rectangular parallelepiped parts, 801 and 802, extended by triangular cheeks, 803 and 804 respectively. The vertex of the triangles being located in the rotation zone (axis ^ 2). The enclosure also comprises a horizontal bottom wall 805 arranged between the rectangular parallelepiped parts, 801 and 802, of

  so as to leave an open area 806 facing the teas.

  FIG. 2C represents in space, in view of quarter-quarters, open face, facing the enclosure 80, the moving part 81. Wile in the form of a box open on the one of the faces. Wile has a vertical rear wall 815, intended to close the member 8, a horizontal bottom wall 814, two lateral walls 811 and 812, and an upper wall slightly inclined relative to the

  horizontal plane formed by the bottom wall 814, typically around 30.

  In the closed position (state 1), the movable piece 81, in dotted lines in FIG. 2A and referenced 81 ', is embedded in the enclosure 80. The bottom wall, in dotted lines and referenced 814', is then in horizontal position due to the

  rotation around axis A '(shaft 807). The lower member 8 is completely closed.

  In the open position (state 11), the movable part 81, playing the role of the drawer 21 (FIG. 1B), comes out partially from the enclosure 80, the lower wall 814 frees the open area 806 facing the teas (ground S: figure 1A). We can therefore

  introduce a dj djection (figure 1A).

  As before, a drive and control mechanism (not shown) is provided for relative movements of the moving part 81 with respect to the fixed part 80, of pure mechanical type (that is to say with manual control). , motorized or mixed. This mechanism can be quite similar to those already described with reference to Figures 1 B-1C and 1 H. there is no need to re-describe them further. The only notable difference is that these mechanisms must cause relative rotational movements of the two parts, 80 and 81, around the axis A, and not a linear translation movement. Likewise, there is advantageously a bag (not shown) introduced partially inside the moving part 81 and which overflows on the fixed part 80, so as to be able to partially envelop the lower member.

  8 and to be subject to it temporarily.

  The operating mode is identical to that previously described and it

  nor is it necessary to re-describe it.

  An example of a third embodiment of the device according to the invention, reference 1 ", will now be described with reference to FIGS. 3A and 3B. In these figures, identical elements have the same references and

  will only be re-described in tent if necessary.

  In fa, con analogous to the second embodiment described opposite 0 of Figures 2A to 2C, the lower member, now reference 9, comprises two parts, a first, 90, fixed, subject to the handle 3, and a second, 91 , movable in rotation relative to the first 90, around a rotation shaft 903. However, according to an important characteristic of this embodiment, the axis of rotation ^ 2 is vertical. The two pieces, 90 and 91, in

  relative wind movements essentially cylindrical and coaxial.

  FIG. 3A illustrates, in space, in view of high quarter-quarters and partially broken away, the arrangement of the two parts, 90 and 91, one with respect to the other. The moving part 91 is arranged inside the fixed part 90. Both have a vertical cylindrical wall. The upper wall 901 of the fixed part 90 is full. The bark made in Figure 3A shows the part

mobile 91.

  FIG. 3B illustrates a view from below of the arrangement of the two parts, and 91. The bottom walls, 902 and 911 respectively, only cover

  partially their lower surfaces, for example half of these surfaces.

  In this FIG. 3B, the two parts, 90 and 91, have been shown in a semi-open position (state called lil), between the closed position (state 1, in dotted lines: reference 91 ') and the open position (state 11: not explicitly represented), which allows the introduction of djections dj (Figure 1A). The bottom walls, 902 and 911, of the two parts, 90 and 91, in their relative rotational movements around the rotation shaft 903, of vertical axis ^ 2, have a

  so-called "butterfly" type operation.

  As previously, there is provided a drive and control mechanism (not shown) of the relative movements of the movable part 91 relative, of pure mechanical type (that is to say, manual control), motorized or mixed. This mechanism must cause relative rotational movements of the two parts, 90 and 91, around the axis 2. Likewise, there is advantageously a bag (not shown) partially introduced inside the moving part 91 and which overflows on the fixed part 90, so as to be able to partially envelop the lower member

  g and to be subject to it temporarily.

  The operating mode is identical to that previously described and it

  nor is it necessary to re-describe it.

  On reading the above, it is easy to see that the invention

  achieves the goals it has set for itself.

  The device for collecting droppings according to the invention is both simple to use, inexpensive because it does not require expensive organs and is reusable (with the exception of inexpensive bags, a priori of the disposable type for hygienic reasons), and allows safe transport of waste

collects without risk of soiling.

  It should be clear, however, that the invention is not limited to the only examples of embodiments explicitly described, in particular in relation to the

Figures 1A to 3B.

  Elijah is not limited to just collecting dog excrement either.
