Description

5 This utility model has as its object a dirt collection device for drills or the like, which together with the drilling element of the drill, and especially in the applications that require the use of crowns, directly collects the dirt or dust generated by the process of drilling, without the dirt falling into the machine or the place where the action occurs.

STATE OF THE TECHNIQUE

At present, when performing small drilling operations using drills

or the like, a large amount of dirt is generated, especially dust, which is only collected once the drilling action of the wall or ceiling has been completed.

The dirt that is generated is spread both by the location where the action has been executed, as by the machine itself or on the operator who performs the function, which is also especially annoying in the event that the dust is introduced into the eyes of the operator.

20 The latter case requires special attention, since if the operator is physically affected by the presence of foreign elements in his eyes, this can harm both the operation he is doing, as well as the physical integrity of the operator, since Small solid impurities in the eyes can lead to a small eye infection.

DESCRIPTION OF THE INVENTION

The technical problem that solves the present invention is to achieve an element or device that collects the dirt generated by drilling at the time of action,

30 preventing the location where the operation is carried out ends up covered in dirt, such as the dust generated by the drill itself or that this dirt ends up in the operator's body, especially in his eyes.

For this, the dirt collection device for drills or the like, object of the present specification is essentially characterized by comprising a flexible body capable of compressing itself and recovering its initial position, preferably materialized in flexible and transparent plastic; and that in its lower part incorporates a spherical support by means of a tongue and groove anchoring system, and where said support has a diameter greater than the body so that the coupling is by pressure and avoid

5 that can come off.

Thanks to its special design, the device recommended here manages to collect the dust generated in drilling processes of roofs or similar by means of crown drills, such as, for example, in lamp placement operations, avoiding that when drilling the

10 roof, the dust that is generated, can fall on the operator, the machine itself or the objects present in the location where the drilling is performed.

Throughout the description and the claims the word "comprises" and its variants are not intended to exclude other technical characteristics, additives, components or steps. For the

Those skilled in the art, other objects, advantages and features of the invention will emerge in part from the description and in part from the practice of the invention. The following examples and drawings are provided by way of illustration, and are not intended to restrict the present invention. In addition, the present invention covers all possible combinations of particular and preferred embodiments indicated herein.

PREFERRED EMBODIMENT OF THE INVENTION

A preferred embodiment of the invention is shown in the attached figures. More specifically, the dirt collection device for drills or the like essentially comprises a first flexible body (1) that is capable of compressing itself and then recovering its initial position, preferably materialized in flexible and transparent plastic; and whose main function is to collect the dirt that is generated in the drilling process.

In its lower part, said first body (1) has a spherical support (2) coupled by means of a tongue and groove anchoring system. This support (2) has a diameter substantially greater than that of the flexible body (1) so that the coupling is by pressure and prevents it from detaching. In turn, with said coupling it is avoided that the generated dirt can be introduced between both elements.

The support (2) incorporates a concentric ring (3), arranged perimeter and that fits into a groove (1a) present in the body (1) as a flange, for the union between the body (1) and the support ( 2).

The support (2) also presents another series of housings in its central base. In addition, the support (2) comprises at least one recess (4) in the lower part of the support (2), wherein said recess (4) has a plurality of housings (4a) where a plurality of rolling balls ( 4b), at least one per accommodation (4a).

To protect said balls (4b) and prevent them from getting out, a cover (5) is placed that fits the support (2) by means of a plurality of flexible pins (5a) with tabs that allow the introduction of said cover (5) avoiding You can leave your site. This cover

(5)

It has enough clearance to allow its rotation while the body (1) and the support (2) remain fixed.

(2)

and a variable number of millimeters protrudes therefrom.

The cover (5) in its upper part has a hollow and spherical hollow (5b) in the center thereof, to allow the drill bit (11) to pass through. Said cavity (5b) crosses the support In the cavity (5b) a rigid element (7) is coupled in its outer part, while in its flexible inner part, the cavity (5b) has a spring that generates a pressure on the cavity (5b), but allowing its rotation, while preventing the generated dirt from coming into contact with the rolling balls (4b).

The cover (5) incorporates a central perforation with a series of notches, where a flexible element (6) is attached, which fits the perforated thanks to the fact that it has a groove in its outer perimeter as a female. The flexible element (6) has the function of preventing the dirt that is produced when drilling and that is deposited in the body (1) from going outside,

10 creating a tight compartment.

The lower part of the drill bit (11) of the crown (10) passes through the flexible element (6) and attaches to the drill.

15 The support will be made in one piece by plastic injection, but it is perforated by small holes produced by a counter-output necessary to materialize the tabs of the flexible pins (5a). These holes communicate the upper part of the support

(2) with its lower part, where the housings (4a) where the bearing balls (4b) are located. To plug them, a sealing ring (8) is provided with a

20 series of stems (8a) in its lower part to be introduced into the holes, and thus prevent the generated dirt from spilling.

In a practical, non-limiting embodiment, the device herein recommended will incorporate second pins (12) jointly joined to the lid (5), and which allow the crown to be grasped

25 (10) of the drill, increasing the grip of the device, and facilitating the rotation thereof, during the drilling operation.
