Description

Pool cleaner.

Object of the invention

The present invention relates to a pool cleaner, of the type that includes a car with wheels and at the bottom at least one brush with bristles for the extraction of particles or deposits attached to the bottom and the walls of the pool.

Background of the invention

For cleaning the particles and sludge that deposited at the bottom and walls of a pool are used about appliances called pool cleaners, consisting of a car provided with wheels for its movement along the bottom and the Pool walls and a handle for handling from outside from the pool. At least one car is mounted on this car lower brush which is the one that detaches and separates the particles or accumulated deposits on the surface.

This brush consists of a body elongated prismatic presenting on one of its sides the bristles of cleaning. Currently, for this brush to oscillate vertically with respect to the car, and can adapt to small irregularities from the surface, it is fastened to the car by two screws ends substantially parallel to the bristles, mounting around to the stud of each screw a helical spring that tends to move the brush towards the front carrying area of the bristles

When setting the brush contact the bottom surface the springs yield to a greater or lesser extent favoring the adaptation of the brush to the surface to clean.

The problem with these pool cleaners is that, between screws and springs, include a large number of small parts for oscillating brush clamping, which, in addition to Increase the final cost of the product, complicates the assembly of the brush and carries the risk of loss of any of the pieces.

Description of the invention

The pool cleaner of this invention presents a series of technical peculiarities that allow reduce the number of parts necessary for correct operation and make a quick and easy change of brushes

According to the invention the body of the brush presents on the upper face, opposite to the carrier of the bristles, flexible tabs that rest against the bottom of a defined in carriage and tend to move the brush towards the lower zone, that is towards the outside of said cached

The brush is mounted inside the cached with the possibility of upward and downward movement, according to the greater or lesser flexion of the tabs, and retained in the inside said recessed by means of blocking.

Thus the brush is suitable to adapt to the background or Pool walls to be cleaned by flexing said tabs as the car moves. To get one proper brush hold and allow its displacement vertical, the aforementioned recess has guides at its ends vertical

Means blocking the brush body in the inside of the pocket are constituted by stops that are introduced through some end holes of said recess and that prevent the ends of the body of the brush from getting out  accidentally of it. These bumpers can be placed and removed very easily, allowing quick assembly, disassembly or Brush replacement

The body and the tongues of the brush can be formed in a single piece of plastic material, reducing the number of components needed to subject the brush and without using conventional screws and coil springs.

Description of the figures

To complement the description that is being performing and in order to facilitate the understanding of characteristics of the invention, is attached herein descriptive a set of drawings in which, with character Illustrative and not limiting, the following has been represented:

- Figure 1 shows an elevation view of the cleaner brush.

- Figure 2 shows a detailed view of the inside brush recessed before its end is locked with the corresponding cap.

- Figure 3 shows a detailed view of the brush inside the recess after its end is locked with the corresponding cap.

- Figure 4 shows a bottom view of the cleaner truck with the brush arranged in the recessed and with a stop ready to be inserted and block the exit of said brush.

Preferred Embodiment of the Invention

As can be seen in the figures referenced pool cleaner includes a car (1) with wheels (2) for movement and a handle (not represented) for handling.

The car (1) has a recess (11), provided of vertical guides (12) vertical at its ends, in which a cleaning brush (3) is mounted, with the possibility of vertical displacement.

This brush (3) consists of a body elongated (31), preferably prismatic, which has on the face bottom of cleaning bristles (32) and presenting on the face opposite upper two flexible tabs (33), divergent towards the upper area and intended to act against the bottom of the recess (11) for forcing the brush (3) towards the lower area.

For blocking the brush (3) inside the recessed (11), the carriage (1) comprises locking means constituted by two lateral stops (4) that are introduced through of holes (41) defined at opposite ends of the recessed (11), preventing the ends of the body (31) from being able to free of the recess (11) due to the thrust of the tabs (33). These holes (41) are extended in paths guides for the stop retention (4) with respect to vertical guides (12).

In a preferred embodiment the body (31) and the tabs (33) of the brush (3) are constituted in a body single piece

Once the nature of The invention, as well as a preferred embodiment, is for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not imply an alteration of the essential features of the invention claimed in continuation.
