FR2837225A1 - Disposal unit for pets' excrement comprises grid with pedal-operated tilting bars for discharging excrement into road or household drains - Google Patents

Abstract

The disposal unit consists of a grid (1) with a frame and tilting bars (2) that are opened by pressing on a foot pedal (3) to allow excrement to be pushed through with a special stick that fits into a support with a cleaner and disinfecter. The bars are opened and closed by a roller and ramp mechanism beneath the grid which incorporates gas cylinders to control the pressure required so that the grid cannot be opened by children. Other gas cylinders damp the bars' opening and closing action. The cleaning stick can be fitted to a coin-operated machine that also incorporates a feed dispenser.

Description

in that the treating product (T) allows the diffusion of odor by the

opening 220.

  The present invention relates to a device for facilitating evacuation to

  sewers of the dogs' jettisoning the streets, sidewalks and squares of the cities.

  The cleaning of passing voices is traditionally done by sweeping, high pressure jets. In some large cities, motorized vehicles adapted to this type of maintenance are used by municipal employees and / or subcontractors. The

  overall cost is very important for the community.

  The device, according to the invention, makes it possible to remedy these drawbacks and to limit

  the high-pressure cleaning at the only sewer mouths equipped with the system.

  The accompanying drawings illustrate the invention.

  Figure N 1 shows in section the 3 main elements of the device.

  Figure n 2 schematically represents the main element of the device.

  << CANIPRGTTl >> object of the present invention.

  Figure 3 shows a technical variant of the present invention.

  With reference to the drawing N 1, the device is constituted of three basic elements.

  A frame << A>? is sealed in the sidewalk (concrete, paving, tar). This piece includes the "B" system, called "CANIPROYi", and a "C" connection pipe at the downspout. The junction between the conical pipe and the device is sufficiently watertight for

  avoid dispersal of water and detergent in the soil.

  With reference to de s s i n N 2, schematic representation of the system e << B >> << CANIPRO \ I >>. The number of lamellae << F>? is a function of the existing sewer plate or to create as needed. Reference piece << E >> represents the frame. A dog owner presses the "D" command when his animal has completed his dejections. A control mechanism (mechanical or otherwise) allows the opening of

  lamellae. This opening allows the fall of the canine excrement in the sewers.

  With reference to drawing N 3, representation of a variant of the mechanism, the piece << G ?? is displaced in translation by the << D?> command mechanism. The piece "G" induces a rotation greater than 90 to the slats, opening the voice to the fall of the canine ejections in the sewers Detailed analysis of the functions which the system must satisfy O) Limits of the system The plate of sewer << CANRo YI>?

Pressure).

  To facility of product installation (existing sewer plate frames in

the vast majority of cases).

  3) Exterior elements to the system (outdoor environments) to Dog excrements to sidewalks to sewer pipes to dust, gravel water under pressure to vehicle wheel (truck, car etc ...) to the feet of passers-by 4) Functions fulfilled by Product (Main Functions) FP1 When opening the system, the feces do not stick, and fall

in the sewers.

  FP2 The system allows immediate evacuation of water (from

runoff and underpressure).

  ) Constraints supported or exerted by the product (Constrained functions) l - 3 See Figure N 2

  FC1. Excrement does not adhere to the << cANRoSl >> system.

  FC2: The system is resistant to pressurized water and detergents FC3: Dust, stones, pollutions, wind without effect on function FP1, << opening of the system. >> FC4: The system resists the weight of a truck axle (FC4 (a) and FC4 (b)) FC5: Systematic closure of the product, which no longer wishes to leave it open. FC6: Impossible opening of the system other than by the mechanism provided for in

this effect.

  FC7: No risk of a passer-by falling due to the system. 6) Use criteria 1- System life: 30 or 150,000 cycles of opening / closing 2- The system adapts, except in case particular, to existing manhole frames. 3- The system must be light (manipulation by installers and easy opening)

  4 - The system must withstand the load of a truck axle (6 tons).

  - The deformations accepted must not generate the mechanism of opening 6 - The lamellae wind are expected not to retain by adherence the canine excrement. Depending on the technological choice (resistance of the materials / weight) between the criteria of use N 3 and N 4, it will be possible to give priority to the lightness of the system. Implantation

  and the markup of the << CANRO; 1 >> will be adapted accordingly.
