Suction handle kit for hammer drill.

Abstract

The invention relates to a dust extraction kit (1) for a rotary hammer (17) designed to collect dust during drilling with rotary hammers (1). The dust extraction kit (1) is characterized by the replacement of the rotary hammer's (17) handle with a handle incorporating a vacuum cleaner. This kit is essentially intended for collecting dust during drilling with a rotary hammer (17).

Description

Title of the invention: Suction handle kit for hammer drill.

[0001] The present invention relates to a dust extraction kit for a drill to collect the dust caused by drilling.

[0002] Dust extraction during drilling is traditionally done with a stationary vacuum cleaner connected with a hose to the drill, or a vacuum cleaner that clips onto the drill, preventing the employee from using the device correctly. Both solutions are heavy, bulky, and make the use of the drill difficult in confined spaces and present a danger to the user due to its weight and ergonomics.

[0003] The present invention makes it possible to remedy these disadvantages by replacing the handle of the drill with a handle into which I will integrate a dust extractor, the extraction kit will have two functions, the holding of the drill by the user and the extraction of the dust caused by drilling, this will solve the bulkiness and avoid any risk of accident, with a lighter weight and reinforced holding of the drill, a considerable gain for the user and the tool manufacturers.

[0004] The attached drawing illustrates the invention:

[0005] Fig. 1 shows a cross-section of a suction handle kit (1) for a drill.

[0006] With reference to the drawing, the suction kit (1) will be in the shape of a 90° right angle, it will fit perfectly on the drill (17) without changing the traditional shape of the drill (17).

[0007] For the vertical part of the device (1) the vacuum cleaner will be equipped with a motor (5) and a dust container (7) which will form a handle with a non-slip coating to fit the user's hand well, they will be interlocking with a quarter-turn quick-release system (2) to allow emptying of the dust container (7) when necessary, inside the dust container (7) there is an interchangeable conical filter (6) to prevent dust from accessing the motor (5), a flap (8) above to manage the dust flow and a rigid transparent window (14) in the center to monitor the filling of the dust container (7), at the bottom of the suction handle there will be a coiled power cable outlet (3) which plugs into the plug (20) of the drill to power the suction kit (1) and an opening (4) to vent the airflow from the motor (5).

[0008] The horizontal part of the device (1) will have an interchangeable cylindrical spring-loaded dust collector (9) with a waterproof polyester coating; it will be held with the angular part (13) of the suction kit (1) with a quarter-turn quick-release clamping system (10).

[0009] The angular part (13) of the suction kit (1) shall be rigid and sealed, it shall form with the dust bin (7) a single piece at a right angle of 90° for greater strength, it shall be locked through its cylindrical passage opening (12) in front of the drill (16) by means of a clamping system (11), a passage for dust is provided at the bottom of the angular part (13) between the opening (12) and dust bin (7).

[0010] The suction kit (1) is adaptable to any electric or battery-powered drill (17), manufacturers must adjust their device (1) according to the characteristics of their drills.

[0011] The suction kit (1) will be controlled and powered by the operating button (18) and the battery (19) of the drill (17)

[0012] According to the particular embodiments: - The vacuum cleaner can be powered by the drill's battery or its own battery. - The vacuum cleaner can be powered by a corded drill. - the vacuum cleaner can be powered by a device located at the level of the fixing the suction kit in order to conceal the power cable. - The device can be adapted to all drills. Manufacturers can adapt it to their drill by adjusting the voltage, size, power and wiring. - The corner section and the dustbin can be separated with a fastening system. - The shape of the kit may differ from that described in the text. - The suction handle can have an LED to illuminate the work area.

[0013] Operation: - Through the opening (12) the device (1) is slid onto the front of the perforator (16) and locked with the fixing system (11). - Connect the plug (3) of the suction kit (1) to the plug (20) of the drill (17). - Position the drill (17) on the area to be drilled. - Press the operating button (18) of the drill (17), this The latter, as well as the vacuum cleaner, begin to work. - The flap (8) opens and lets the dust through. - The wick (15) pierces and emits dust, which is collected in first by the spring collector (9), then it is very quickly attracted by the vacuum cleaner and stored in the dust bin (7). - Once you stop pressing the operating button (18) of the drill (17), the drill and the vacuum cleaner stop working. - The flap (8) closes and prevents dust from coming out of the dust container (7).

[0014] This suction kit (1) is specifically reserved for the drill (17) to vacuum up dust during drilling.
