Abstract

The utility model relates to the field of meeting human needs, and specifically to keeping and caring for pets, to cleaning metabolic waste thereof and small household waste, and to performing other household chores. The aim of the present utility model is to reduce the size and weight of the device, to increase the ease of manufacturing thereof, and to allow for novel functional possibilities. Said result is achieved in that a device includes two hingedly-connected grippers, a rod and a handle. The rod contains, normally, a plurality of telescopically-connected hollow segments which retract into one another when made compact. A cable is passed through the segments and is connected to the handle on one side and to the grippers on the other side. The grippers are hingedly-connected to the rod and are pushed apart by the energy of a spring which is installed, normally, within the hinge. The handle is hingedly-attached to the rod, and when the handle is twisted, the cable tightens, causing the grippers to converge. When the handle is released, the grippers diverge under the effect of the spring, and the cable slackens. When the device is retracted, the cable normally remains within the rod segment cavities.

Description

DEVICE FOR CLEANING FOR PETS

The utility model relates to the field of satisfying human needs, in particular the maintenance and care of domestic animals, the cleaning of their livelihoods, small household waste, and other household chores.

The prior art there are many devices designed for these purposes: RU2113162, RU2006112809, JP2004222554, US2008012366, FR2880240 JP2006101821, US2002056419, etc. All devices for collecting animal excrement can be divided into several groups:

- portable animal toilets (for example, US 4,555,132; US 4,042,269);

- various designs of scoops (for example, US2008012366, JP11 13437);

- tongs, grips (for example, JP2003023903, JP2003274783);

- napkins, gloves and other devices requiring direct contact of hands with waste (JP2007282556, JP2005046127)

In general, the listed devices are quite cumbersome and complex in design or require tilting for cleaning. In addition, most devices must be washed and disinfected after use or, they must be completely disposed of.

There are a number of devices in which disposable bags are used for waste collection: JP11113437, JP10165030, JP7255309, JP8242719, however, these devices are also large or require tilting.

A device for manual collection and removal of animal excrement is known (RF patent for PM Nei 12608). It contains a rigid base with a locking plate, an elastic insert in the front end and a handle located on the locking plate. A cutout is made on a rigid base in the front end, and protrusions are made in the front and rear ends, respectively, on the locking plate, and the base with the locking plate are connected by a U-shaped frame on which an elastic insert is installed that can be folded. Such a device allows you to clean waste without tilting, but it is difficult to use and has limitations in use - can be used on a relatively flat surface.

Another known device for collecting solid and paste-like waste (RF patent for PM N ° 107922) contains a handle pivotally connected to movable elements. The handle consists of two interconnected holders, on one side of which are placed grippers for the fingers, with the other on them through a swivel nut and a support spring mounted movable elements in the form of rotary rods. The rods are made with the possibility of rotation and fixing in a predetermined position and a single-use polyethylene prefabricated container is placed on them. This device has a relatively large overall dimensions and is difficult to manufacture.

The device (RF patent No. 2348340) is intended for the collection of solid and paste-like waste, preferably on the street. The device comprises a handle and a scraper fixed on the handle, kinematically connected to each other by means of a block mechanism and a traction link. The handle is mounted on one end of the handle with the ability to move, and the scraper is mounted on the other end of the handle articulated. The device is equipped with an additional scraper, while both scrapers are jointly pivotally mounted on the handle and kinematically connected with the handle. The scrapers are spring-loaded relative to each other and between them a collection tank is placed, the neck of which is fixed on the outer surface of the scrapers. The handle is made integral of at least two parts, which are interconnected with the possibility of relative rotation and fixation in a given position. The handle contains a hollow U-shaped holder on which the scrapers are pivotally mounted. In each of the branches of the holder there is a mechanism for turning the scrapers, having a pin mounted along the axis of the branch with a thread in its part facing the handle. The pinion is mounted on the pin with the possibility of movement along its axis, which is in gear engagement with the other pinion. The axes of the gears are mutually perpendicular, and the traction link passes from the block mechanism through an axial hole in the other gear to each of the scrapers.

The device is distinguished by a relatively large weight and dimensions, and it is relatively difficult to manufacture. The external location of the rotary mechanism will lead to its pollution when working on the street.

A device for manually collecting and removing animal and / or garbage excrement (RF patent for PM N ° 75915), including a handle made in the form of a cylindrical pipe with a spring-loaded rod located in it, and a container for collecting excrement and / or garbage mounted on the end of the handle characterized in that the container for collecting excrement and / or garbage is formed of two flaps, movable and stationary, made in the form of curved plates pivotally attached to each other, and the fixed flap is rigidly fixed to the end of the pipe, and the movable leaf is connected to the spring-loaded stem with the possibility of a turn relative to the stationary leaf. This device is also distinguished by relatively large overall dimensions, and there is no possibility of compact carrying.

As the closest analogue, a device for cleaning pets and a kit containing such a device were selected (RF patent for ПМ Ν ° 77749). This device contains two levers pivotally connected, each of which includes a grip, a rod, a handle, and the rod is made sliding.

The device is relatively material-intensive, since it includes two rods, and due to the handles fixed relative to the rod, it is still not compact enough. In the manufacture requires a relatively large number of technological operations.

The purpose of this utility model is to reduce the dimensions and weight of the device, increase the manufacturability of its manufacture, and the emergence of new functionality.

This utility model is aimed at creating a lightweight, compact, convenient device for cleaning animal excrement, garbage, household waste, etc., which excludes direct contact of the user with this waste. Due to additional nozzles, the inventive device can be used to perform other household functions, such as, for example, getting items from remote, inaccessible places, picking fruits, pruning trees, etc.

The claimed result is achieved in that the device includes two articulated grips, a rod and a handle. The bar contains at least one hollow elbow. There can be several such knees, in this case they are telescopically connected and, when folded, are retracted into each other. The cross-sectional shape of the knee can be arbitrary and is determined by the strength characteristics of the material used and the requirements for the appearance of the product. A cable is missing inside the hollow knees, attached to the handle on one side and grips on the other. The grippers are attached to the rod through a swivel joint and are bred by the energy of the spring, which is usually installed inside the hinge. The handle is pivotally attached to the rod, while turning the handle, the cable has the ability to stretch, shifting the grips. When the handle is released, the grips diverge under the action of the spring, pulling the cable. When folding the device, the cable is usually located in the cavities of the knees of the rod. Grooves can be made on the bar, where the handle and grips are removed when the device is folding. Additionally, the device may contain latches, latches and springs, allowing you to lock the device in the folded and working condition.

In the folded state: the knee of the rod is assembled, the handle is rotated and placed along the rod, the grips are folded and rotated along the rod. All device s It is a small pencil case that can even fit in a handbag (the total length of the device usually does not exceed 20cm). In the working (deployed) state, the device allows a person holding it in lowered hands to reach the ground with grabs (total length from 60 to 120 cm).

Typically, the device is made of metal (preferably duralumin) or plastic. Movable joints (hinges), springs and clips are usually made of steel.

The described device is included in the waste collection kit, which also includes a disposable bag worn on the grips from the outside. The material of the bag must be cheap and sufficiently flexible, and the bag must be shaped so that the grips can move along the working amplitude inside the bag. Usually take plastic (polymer) or paper bags. Preferably, the bag contains an additional pocket where waste can accumulate.

The essence of the utility model is illustrated by the following drawings:

Figure 1 (a) - (c) shows a device made in accordance with this utility model;

Figure 2 presents an embodiment of the grippers and swivel;

Fig. 3 shows a device in a folded position;

Figure 4 presents the principle of operation of the devices;

Figure 5 presents the device with an additional nozzle for trimming bushes and tree branches.

In FIG. 1 (a) shows the device in the deployed (working) position. The device includes a rod 1, a handle 3 connected to it by a hinge 2, two grips 4 and 5, which are connected to the other end of the rod by a swivel 6. The rod itself consists of three hollow elbows 7 connected telescopically. A cable 8 is missed inside the hollow knees, attached to the handle 3 on the one hand, and on the grippers 4 and 5 on the other hand. A spring is installed inside the hinge joint 6 (not shown in Fig.), Which grips the wires with its energy and pulls the cable 8. When turning the handle 3 the cable 8 is drawn into the rod, bringing the grips 4 and 5 (Fig. 1 (b) and (c)). When the handle is released, the grips under the action of the spring again diverge, pulling the cable. The grips are usually made in the form of an angle, one side of which lies in a plane parallel to the rod (sides 4 'or 5', respectively), the other (sides 4 "or 5") makes an angle from 90 to 120 ° with it. The sides 4 'and 5' are usually made of different lengths (in particular, 4 'shorter than 5'), so that when reducing the grips one of them ^■ is located above the other. In addition, the sides 4 'and 4 "are connected by an additional hinge 9 with a latch, which allows you to fold the grip so that its sides become parallel. Accordingly, the sides 5 'and 5 "of the gripper 5 are connected by an additional hinge 10.

Figure 2 presents an embodiment of the grippers and swivel. The connection 6 is made as follows: inside the sides 4 'and 5' there are grooves in which a rotary spring 11 and a sleeve 12 are placed, which serves as the axis of rotation of the grippers 4 and 5. The whole structure can be attached to the rod by means of rivets 13.

After use, the device can be folded into a compact pencil case (Fig. 3). For this, the knee 7 of the rod 1 are moved into each other, the handle 3 is rotated and placed along the rod. The cable 8 is located in the cavities of the knees. The combined grips 4 and 5 are folded so that all of their sides 4 ', 4 ", 5', 5" become parallel. Then they turn around the axis of the connection 6, located along the bar 1. The total length of the device usually does not exceed 20 cm and can even fit in a handbag.

For use, the device is deployed in the working position and put on the grips package 14 (Fig. 4 (a) and (b)). When breeding the grippers under the action of the spring, the lower face of the packet forms a stretched membrane that easily bends inwardly into the plane of the grippers under external influence. The device presses the retractable object 15 and by means of the handle, the grips are reduced. The item is inside the package above the grips. Then the package 14 is removed from the grips, while turning inside out (this happens naturally if you pull the edge of the package). Garbage is packed and disposed of, and a new bag is put on the grips for future use.

Preferably, said package contains an additional pocket where waste can accumulate. Then the device in this configuration can be used several times, and the package is removed after filling the pocket.

The device can be used to perform other household tasks, for which the grips provide mounting points for additional nozzles (Fig. 5). For example, blades 16 and 17 can be mounted on horizontal grips 4 ", 5", then the device can be used as garden shears.

The inventive utility model is not limited to the described options, but also includes other design solutions that allow you to achieve the stated result. The versatility of the proposed device allows you to find him a variety of domestic applications.
