Description

A DEVICE

Field of the Invention

The present invention relates to a device for collection of drilling detritus.

Background

Societies increasingly are modernising at ever faster rates, as technology.

building standards and expectations change.

This change has effects on buildings as much as anything else, and conversely many buildings date from, and are frequently prized for dating from, earlier times.

In particular in a modern home or business growing reliance is placed on electrical provision and equipment.

Tn older homes or business there is minimal electrical provision, and it can be very dangerous to overload existing sockets with appliances.

Increasing numbers of people are choosing to upgrade these homes or businesses to ensure that electrical provision is sufficient, as well as for aesthetic or personal reasons.

As a consequence many existing homes and business have work undertaken to improve the building such as drilling holes in walls, which can frequently cause great disruption to such as skirting boards, flooring, wall covering and dccoi as the drilling raises and disperses dust and other detritus.

Prior Art

Accordingly a number of patent applications have been filed in an aftempt to resolve the problem, including the follovving: German patent application DR 202 006 005 365 (SCHNEIDER) discloses a device wherein a shaft of a drill bit is guided through the bottom of a wide transparent bowl touching the wall or object to be provided with a large hole with its front edge. Two elements of a fixing screw are located at the inner and the outer surface of the bottom of the bowl. A flexible pipe connected to a suction unit thcilitates the removal of dust caught in the receptacle. When the hole saw is moved through the wall or panel a helical spring surrounding the shaft is compressed.

Granted United Kingdom patent GB 2 436 682 (RYAN) discloses a drill debris receptacle constructed from a single sheet of light weight material selectively coated with an adhesive of a strength suitable for sticking a wall engaging surface of the receptacle to a wide variety of wall surfaces and removing the receptacle without damage to the walls' surfaces. and where the same strength adhesive is used elsewhere in the construction of the receptacle such that, by means of folding, two of the material's surfaces coated with the adhesive are brought into direct contact with each other to make a. much stronger bond for is fixing the receptacle together securely.

Granted European patent EP 1 459 841 (ARTCII) discloses a dust collection unit suitable for use with a hand held drilling and/or hammering tool, comprising: a shroud adapted to extend around a tool or bit of such a hammering and/or drilling tool so as to collect dust in an airflow passing through the dust extraction unit which dust is generated by such a tool or bit; and a tube like extension sleeve which extends forwardly from the shroud, with respect to such a. tool or bit; characterised in that a. slideable sleeve is slideably mounted on the extension sleeve so as to move betveen a retracted position in which the forward rim of the extension sleeve is engageable with a surface to be worked and an extended position in which a forward rim of the slideable sleeve is engageable with a surface to be worked and the forward ends of the extension sleeve and the slideable sleeve are shaped differently from each other so as to fit against a different shape of work surface.

Granted United Kingdom patent GB 2 383 965 (EINHORN) discloses a drill dust collector comprises of a flat paper pocket with a slot. A light non-permanctit adhesive surrounds the slot that is placed vertically over the pointt which is to he drilled. The pocket is opened and the dust that escapes from the hole as it is being drilled falls into the pocket. This is then removed and disposed of Granted French patent FR 2 823 689 (BALSTIDFI) discloses a receptacle comprises a rear wall with a self-adhesive band in its upper part for fixing against a medium to be worked. A front wait is attached to the rear wall by its bottom and by its lateral edges and is held at a distance from the rear wall to define an tipper opening and a debris recovery volume. There are two folding lines located under the adhesive band which after folding are stuck against the front wall.

United States patent application US 2 689 594 (WENDT) discloses a disposable article receiving pocket comprising in combination: a subgtantiallv rectangular back portion having an extended non-linear lower edge; a complementary substantially rectangular front portion coextensive with and overlying all but an area adjacent the tipper edge of said back portion, said back and front portions being secured together along their coniplcnientarv edges; a tab projecting laterally outwardly from said upper edge of said hack portion; a pressure adhesive strip on the rearwa.rdly facing surface of said back portion only, and adjacent said upper edge; and a protective cover for said adhesive strip, one end of said cover overlying said tab.

In contrast the present invention provides a multiple use means of containing the detritus and drill dust created by a drill in masonry drilling in particular and in particular a core cutting drill bit, without restricting movement of the drill or bit.

The invention furthermore assists a. user by containing the relevant items required to carry out the job single handed and at the same time removing the need to place dust sheets down on the ground and then vacuum the floors, carpets and potentially skirting hoards afterwards.

Summary of the invention

According to the present invention there is provided a device for collection of drilling detritus, and storage of parts; including in use two sides. a tray, and means to attach to an independent wall attachment mechanism.

Detailed Description of Figures

is Referring to figure 1, a drilling containment device comprises a plastic tray 1, detachable sides 2 and displaceable lid or cowling 3, wherein the tray is attached to a wall below an area where the iisci wishes to drill a hole, the purpose being to catch any dust created when drilling.

A fiat stamped polyethylene protile could he used to keep costs low and folded to assemble the tray 1.

In some embodiments metal or plastic rods could be combined with the plastic walls and the tray mid in further embodiments may be able to slot in and out.

In further embodiments the device is fonned in reinforced and/or fibre panels and/or having structural strengthening or reinforcement, such as struts 17 shown in figure 1.

The tray is ideally manufactured by single direction injection.

In use the tray 1 and/or sides 2 are hung onto and secured with low tack masking tape 4 for ease of application without any inconvenience of leaving marks once the job is completed. Masking tape having a width of 2 inches is ideal for this purpose.

Slits 5 (which can also he seen clearly in figure 6) arc provided at back edge of each of the side walls 10 of the tray 1. Referring also to figure 7, prior to drilling, the user must slot a length of masking tape 4 through both these slits S at the back of the tray 1. The lower half (that i. approximately half the exact proportion depending 011 the width of tape used) of the masking tape covers and adheres to the top edge of the back 11 of the tray, whilst the upper half extends above the back 11 of the tray with its adhesive area exposed (mostly clearly-visible in figure 5) Ideally, the length of tape torn oft' my the user is longer than the tray, so that the ends of the tape extend outwards beyond each slit 5.

The user may then position the tray caretjilly mid push the device onto the wall, securing the tray in place by applying pressure to upper half and ends of tile masking tape. making it adhere to the wall, so securing the tray in place.

Referring to figures 2 and 3, the hack 11 of the tray 1 extends downwards to form a support board 15, and the rigidity of the tray is reinforced by braces 9 spanning the underside of the tray 1 and the support board 15, the support board and braces helping to keep the device in place and maintain increasing weight in use. The action of the support board and hi-aces 9 combine with the seal 13 to ensure a tight reliable fit.

The injection formed polypropylene tray 1 has a cut-out 7 for access with a drill by the user and to not restrict the movement and positioning of the user and their drill.

The device may be used at this stage. The user drills their hole (either above the masking tape or through the upper half of the masking tape but above the edge of the back 11 of the tray 1), and the dust that is created collects in the tray, rather than on skirting board or clean ca.rpets.

As well as catching the drilling dust, the tray' 1 holds any drill hits. screws or wail plugs that the user requires to catty out their task.

More ideally though, the device is also used with the detachable sides 2. In the pictured embodiment the length of the sides 2 is slightly less than the inner width of the tray (that is, the inner length of each tray side wail 10), so that the bottom portion of each side 2 fits in the tray 1. The sides 2 also incorporate clips 6 to hook on the side wall of the tray 1 to hold the sides 2 in place.

In the pictured and preferred embodiment rubber seals 13 are attached to part of the edge of the sides 2, to sit against the wall as an extra containment feature to form a seal around the working area where the device makes contact with the wall.

The sides 2 may be conveniently attached to the fray 1 after it has been positioned upon the wall using masking tape 4. though the sides could also be filled before the tray is placed in the intended position. The sides 2 serve to further prevent dust and debris from being spread about by the drill.

When drilling over a large area, or using a core cutter, the lid 3 may be employed, especially when using a SDS drill that will typically create a draught. The lid 3 features channels 15 on its lower side edges, so it can be clipped onto the top edge of the sides 2 to help contain dust. Like the sides 2.

the lid may also have a length of seal 12 attached to the edge resting against the wall, to ensure containment of the drilling dust. A shown in figure 1 and 4.

is the lid 3 need not extend from the wall as far as the tray 1.

The curved lid 3 also gives easier usability for the user when rnanoeuvring a drill into position. Figure 8 shows the device in use vith a core cutting drill 20.

In the pictured embodiment the tray 1 can be used to hold screws, drill bits and wall plugs for use on a drilling job. Further compartments (not pictured) may be attached to the device, sides 2 or tray 1.

When not in use, or when packed for sale, the sides 2 and lid 3 may be placed in the tray 1. p
