Abstract

The device is for use with a drill to prevent dust generated by drilling escaping into the ambient environment. The device includes a container 1 having a first side portion secured 2 to a flat surface. A second side portion is, in use, spaced from the first side portion. When a drill bit is passed through the two side portions any dust generated by the drilling of a hole is held within the body of the container. The container may be made from a relatively rigid sheet of paper or cardboard. The first side portion may be secured by an adhesive surface 2 positioned around a hole in the device. Prior to use it may be folded flat so that a number of devices can be carried in a suitable carrying container.

Description

The present invention concerns a device for use by builders and people

involved in home improvements. It is particularly concerned with protecting property such as carpets, furniture and fixtures from the fine dust which is generated by drilling and particularly by drilling holes in walls.

Previously the problem of drill dust has been dealt with by covering the area below a drill hole with a dust sheet. Even this procedure usually results in residual dust having to be mopped up or vacuum cleaned.

In accordance with the present invention there is provided a device for gathering dust generated by a drill bit during a drilling operation, the device comprising a container having a first side portion which can be secured to a flat surface and a second side portion which in use of the device is spaced from the first side portion whereby when a drill bit is passed through the two side portions any dust generated by the drilling of a hole by the drill bit is held within the body of the container.

Preferably the device is manufactured from a single sheet of material of suitable rigidity so as to maintain its shape when in use.

According to a feature of the invention the material is paper or cardboard.

In accordance with another feature of the invention the device can be flattened for storage and then expanded into its operational configuration by applying appropriate pressure to opposing sides of the flattened configuration.

Preferably the first side portion has an adhesive surface positioned around the hole therein and a protective cover is positioned over the adhesive, which cover can be removed when it is desired to use the device.

In another aspect the present invention provides a carrying container holding a plurality of devices each in accordance with any one of the preceding claims. In order that the present invention may be more clearly understood an embodiment thereof will now be described by way of example and with reference to the accompanying drawings in which: Figure 1 is a transverse section through a device according to the present invention secured to a wall and showing a drill bit passing through the device and into the wall; Figure 2 is a plan view of a single sheet from which the device shown in Figure 1 is assembled; Figure 3A and B are respective front and rear views of the device of Figure 1; Figure 4is a view of the device of Figure 1 flattened prior to use; Figure 5 shows how the flattened device of 4 is squeezed to make the device ready for use, and Figure 6 is a perspective view of the device Referring now to Figure 1 of the drawings a device according to the present invention comprises a container body 1 made of relatively strong paper or cardboard. The term "relatively strong" is intended to cover a material with sufficient rigidity so that the container can maintain the shape shown in Figures 1 and 6. As shown at 2 the container I has an adhesive surface by means of which it secured to the surface of a wall 3. Though not visible in this figure the container has holes through which a drill bit has passed. As will be appreciated any dust produced by the drill bit will be unable to escape from the container.

An important feature of the invention is that the device is extremely simple both to manufacture and use. Accordingly the basis of the preferred embodiment is a single sheet of paper as is shown in Figure 2 of the accompanying drawing. The sheet has two main fold lines 4 and 5 which divide it into three sections 6, 7 and 8. Each of the sections is formed with a hole 9. The sheet also has a plurality of sections 10 shown in hatched lines which will be referred to as glue sections. In order to assemble the device shown in Figure 1 from the sheet shown in Figure 2 section 6 is folded towards section 7 along fold line 4 until the hole in section 6 is aligned with the hole in section 7. Next section 8 is folded along fold line 5 towards section 7 also until the hole in section 8 is also aligned with the holes in sections 6 and 7. In this configuration the glue sections are also registered one with the other and are glued together so as to form the completed article. In this embodiment section 8 is folded over section 6 and the outer surface of section 8 which surrounds the hole therein is covered with an adhesive whereby the completed device can be secured to a wall as shown in Figure 1. Normally this adhesive layer will initially covered by a tear-off cover.

The preferred method of manufacturing the basic sheet shown in Figure 2 is by the procedure known as die-cutting. This involves pressing a flat sheet of paper, usually already printed, on to a die form. The die form has an plurality of metal fences or cutters arranged in the form of the shape to be cut. Some of these fences are sharp for actually cutting the sheet whilst others can be blunt so that the sheet is only scored to generate any requisite fold lines.

Each of these fences is surrounded by foam rubber so that the final sheet is ejected after cutting and scoring. Once the sheets have been cut the cut pieces a carried through a suitable machine such as a Bobst (RTM). Such a machine applies any necessary glue and then folds the cut pieces into the requisite final form.

As can be seen in Figure 2 there are a number of other minor fold lines generally indicated at 11. These minor fold lines allow the assembled device to be stored in a flat condition. In this flat condition a number of assembled devices can easily be stored in a single envelope.

When a device in the flat condition is to be readied for use it can be taken out of the envelope and squeezes in the direction of the two arrows shown in Figure 4. The result of this applied pressure, the inherentrigidity of the paper or cardboard material and the minor fold lines 1 1 is that the device flattened for storage enters the expanded condition shown in Figure 6.

It will be appreciated that it is not absolutely necessary to provide the adhesive layer on the container body. Instead a suitable adhesive could be supplied separately. In addition laser cutting techniques can be used to cut the original sheet of paper into the required shapes.

Claims

1) A device for gathering dust generated by a drill bit during a drilling operation, the device comprising a container having a first side portion which can be secured to a flat surface and a second side portion which in use of the device is spaced from the first side portion whereby when a drill bit is passed through the two side portions any dust generated by the drilling of a hole by the drill bit is held within the body of the container.

2) A device as claimed in claim I and manufactured from a single sheet of material of suitable rigidity so as to maintain its shape when in use.
