FR2690606A1 - Cat litter tray, with automatic renewal of litter material - Has conveyor belt as base of tray with belt being started as cat leaves tray, and material is moved into sealed tank and fresh material is provided - Google Patents

Abstract

The comfort tray provided for cats, automatically renews the absorbent material, immediately after the cat has satisfied its natural needs. The cat tray is fitted with a rolling belt, which carries on its upper surface the type of absorbent material usually provided in cat litter trays. When the cat leaves the tray, it operates a contact, which sets in motion the change mechanism. The belt moves the used material through a seal into a used material receptacle. At the same time it draws new material from the reserve material store, and positions it ready for the cat's next requirement. USE/ADVANTAGE - It improves the quality of life of both the cat and its owner, by requiring fewer interventions to renew material used on the cat litter.

Description

The present invention relates to a device for renewing

  automatically absorbent material (commonly called litter) spread in a bin and on which the cat (s)

satisfies its natural needs.

  These natural needs are traditionally met

  in a cat container on the bottom of which is deposited the absorbent material

  -bant (litter) which must be changed as often as the

  cats defile it, on pain of this or these not satisfying-

  - feel their natural needs elsewhere.

  The device according to the invention allows the automatic replacement of the soiled absorbent material and the storage of the latter several times in succession, thus avoiding the disadvantages described, and allowing the absence of the master for several hours and even

A few days.

  The device comprises two parallelepipeds, one horizontal, the cat container (s), the other vertical above a

  end of the first, the reserve of absorbent material.

  The cat tray (s) consists in its upper part of a treadmill whose visible part has the surface of a traditional cat (s) tray, and in its lower part of a drawer itself equipped with a conveyor belt in its lower part for the reception and storage at the bottom of the drawer of absorbent material L

  soiled falling from the upper treadmill.

  When a cat climbs onto the cat tray (s), its presence

  is detected by any means, physical or electronic.

  When it comes down from the cat container (s), the

  detection implements the replacement cycle for the abs material

  -sorbent and storage of soiled absorbent material.

  The treadmills and the cleaning brush of the upper treadmill start, the soiled absorbent material falls on the treadmill of the drawer which drives it towards

the bottom of the latter.

  The new absorbent material automatically replaces the previous absorbent material by gravity by draining from the reserve

  as the upper treadmill advances.

  The device is ready to operate again.

  The operation of the device is electric by batteries

or on sector depending on the models.

  The body of the device can be made of plastic, wood or metal, treadmills of any material used

for conveying materials.

  The device can be manufactured industrially and it

  interests tens of millions of people around the world.
