Description
- This application claims priority to U.S. Provisional Patent Application No. 61/021,320, filed on Jan. 15, 2008, which is incorporated herein by reference in its entirety.
- This patent application relates to a vacuum shroud. More specifically, this application relates to a vacuum shroud, which is used with a vacuum and a drilling tool to remove dust and debris as it is generated by the drilling tool.
- Drilling and other similar processes create undesirable dust and debris. The debris often tends to spread in all directions, is usually difficult to remove, and can be harmful to the operator's health. Many types of debris, such as from fiberglass, can be quite harmful to the health of the worker. Capturing this dust before it can circulate helps ensure a cleaner, safer environment for workers, as well as making it easier to clean up after the desired work is done. In addition, the dust and debris often collects in the power tool itself, such as in the gears, chuck, or motor, and can cause increased wear and a decrease in the tool's life.
- Various devices have been developed for collecting dust during drilling with a hand-held power drill. Many of these devices are designed for collecting drywall dust when a home owner must drill into a wall. Available devices, however, perform poorly when used for drilling into other substances, such as metal where long strings of metal are generated rather than a fine dust. These devices are also difficult to use as a person must hold the vacuum hose and shroud in one hand while drilling with the other hand. Some devices have been created which are attached to the tool itself. While these need not be held independently of the tool, they can inhibit the operator's ability to use the tool, as the bulk of the device and the vacuum hose are cumbersome and limit the ability to accurately position the drill bit.
- Thus there is a need for a vacuum shroud for drilling tools that overcomes the limitations of the available devices. There is a need for a vacuum shroud that efficiently removes debris other than fine dust, such as metal chips and strings. There is a need for a shroud which can be used with curved surfaces as well as flat surfaces. There is also a need for a vacuum shroud which aids the worker in securing the shroud while using the same so that the worker can concentrate more on drilling accurately.
- In some embodiments described below, a vacuum shroud may be made using a flexible material, enabling it to bend and be used on a non-planar surface. Using a flexible material may allow the shroud to seal better to both flat and curved surfaces, such that the vacuum helps hold the shroud to the workplace more securely.
- Vacuum shrouds may also be provided to assist in dust and debris removal in tasks other than drilling in drywall. In some embodiments, a vacuum shroud may include a hole in the upper surface and a wall that extends from the top of the vacuum shroud to the surface to be drilled. The wall may provide support and may prevent the vacuum shroud from collapsing once suction is applied. The edge of the wall in contact with the surface to be drilled may have interspersed slots that allow for dust and debris created from the drilling process to pass through and be collected simultaneously. Vacuum shrouds according to such embodiments may work well for operations such as grinding out rivets which require larger diameter tool bits or additional clearance around the bit.
- Similarly, some embodiments of vacuum shrouds may include a support post attached to the inside surface of the shroud that extends towards the surface to be drilled in order to support the vacuum shroud once suction is applied. Such vacuum shrouds may allow a flexible material to be used with an open hole without causing the collapse of the shroud. In such embodiments, the vacuum shroud may be well suited for drilling metal where longer strings of metal are produced.
- These and other aspects of embodiments of vacuum shrouds for use with power drilling tools are shown and described in the following figures and related description.
- Various embodiments of the present invention are shown and described in reference to the numbered drawings wherein:
-
FIG. 1 shows a top perspective view of an embodiment of a vacuum shroud for drilling tools; -

It is appreciated that it is not possible to clearly show each element and aspect of all embodiments of vacuum shrouds in a single figure, and as such, multiple figures are presented to separately illustrate various details of embodiments of vacuum shrouds in greater clarity.

- Turning now to
FIG. 1 , a top perspective view of an embodiment of a vacuum shroud for drilling tools is shown.Vacuum shroud 10 may include anupper surface 34 connected tolower edge 38, which may be configured to contact a work surface to be drilled, or a surface adjacent thereto.Upper surface 34 andlower edge 38 may be connected bysides FIG. 2 ) betweenvacuum shroud 10 and the surface to be drilled. -
Vacuum shroud 10 may includevacuum port 30 connected toupper surface 34 ofvacuum shroud 10 with opening 26, which may be connected to a vacuum hose, or which may be formed integrally with a vacuum hose.Vacuum port 30 may also be open tocavity 36. Debris created by the drilling process may be removed by a vacuum (not shown) connected tovacuum port 30 through opening 26 throughcavity 36. -
Upper surface 34 ofvacuum shroud 10 may includehole 14 generally enclosed bywall 18 extending fromupper surface 34 ofvacuum shroud 10 towards the surface to be drilled. Thehole 14 may be used to receive a drill or other tool. -
Lower edge 20 ofwall 18 may have one ormore slots 22 formed inwall 18, which may be intersperced.Edge 20 ofwall 18 may contact the surface to be drilled, providing support toupper surface 34 ofshroud 10 and preventingcavity 36 from collapsing when vacuum pressure is applied throughvacuum port 30.Slots 22 may allow air to flow from the interior ofhole 14, throughslots 22, into thecavity 36, and through thevacuum port 30, causing dust and debris to be collected by a vacuum. -
FIG. 2 shows a bottom perspective view ofshroud 10 ofFIG. 1 .FIG. 2 illustrateswall 18 surroundinghole 14,slots 22,cavity 36, and the fluid connectivity and relationship between the various components ofshroud 10. For example, the open fluid communication betweenhole 14 throughslots 22 allows air and debris to flow fromhole 14 throughcavity 36vacuum port 30. - Shroud 10 may provide several advantages.
Wall 18 andslots 22 may allowshroud 10 to keep a stronger vacuum pressure incavity 36, such thatshroud 10 may hold itself to a work surface during use by vacuum pressure, while still allowing proper removal of dust and debris from the work area inhole 14 throughslots 22. This arrangement may allowhole 14 to have a diameter sufficient to allow relatively large tools to work on a surface to be drilled or otherwise work on throughhole 14 while still having airflow sufficient to remove debris and dust from the work surface, while still providing sufficient vacuum pressure to holdshroud 10 against the work surface. - Additionally,
wall 18 or some analogous structure, may supportupper surface 34 to provide additional support toshroud 10 to preventupper surface 34 from collapsing due to vacuum pressure whenshroud 10 is made from flexible material. Thus, the use ofwall 18 andslots 22 may allowshroud 10 to be made from a flexible material and utilizelarger holes 14 without collapse or loss of suction. Using a flexible material (such as a vinyl or rubber compound) to makeshroud 10 may allowshroud 10 to be used on curved surfaces and may allowshroud 10 to seal better to both flexible and flat surfaces and to provide some resistance to sliding on the work surface. This arrangement may keepshroud 10 from sliding around during use and allowingshroud 10 to be more self supporting, i.e. to attach itself to the work surface with vacuum pressure. - Turning now to
FIG. 3 , some embodiments ofshroud 10 may include one ormore support post 50 attached to the lower side ofupper surface 34 adjacent to hole 14, through which a drill bit may be inserted. Similar to the embodiments described with respect toFIGS. 1 and 2 ,shroud 10 may formcavity 36 betweenshroud 10 and the work surface as discussed above. In embodiments such as those described inFIG. 3 ,hole 14 may be open to thecavity 36. In such embodiments,hole 14 may be open to thecavity 36 to allow for capture of longer strings or debris, such as are formed while drilling metal.Support post 50 may extend downwardly towards the work surface to preventvacuum shroud 10 from collapsing when suction is applied, similar to the embodiments ofFIGS. 1 and 2 . The absence ofwall 18, as described with respect toFIGS. 1 and 2 , may allow larger debris to pass throughcompartment 36 andvacuum port 30 for collection and removal. -
FIG. 4 shows a bottom perspective view ofshroud 10. As illustrated inFIG. 4 , post 50 supportsupper surface 34 and may prevent collapse ofcavity 36 without obstructing access tohole 14. Similar to wall 18 of the embodiments discussed with respect toFIGS. 1 and 2 , post 50 may allowshroud 10 to be constructed from a flexible material without the shroud collapsing due to the negative pressure. As discussed above, the use of a flexible material may allowshroud 10 to conform to a curved surface, and may improve the seal betweenlower edge 38 ofshroud 10 and the work surface. The flexible material may also better provide resistance toshroud 10 from slipping around during use. Flexibility may be provided by making theshroud 10 from a flexible PVC or vinyl, or some other material which allows the shroud to function will imparting sufficient flexibility to conform to a curved work surface. -
FIG. 5 shows a side view of avacuum shroud 10 ofFIGS. 1 and 2 oncurved work surface 54 with attachedvacuum hose 62. InFIG. 5 ,drill bit 58 is inserted throughhole 14 in order to drill intosurface 54.Vacuum shroud 10 may flexible such that it may conform to surface 54, allowingbottom edge 38 ofshroud 10 to remain in contact withsurface 54. This may maintain suction and provide for more efficient removal of dust anddebris 66. Wall 18 (or post 50) may, therefore, supportupper surface 34 ofvacuum shroud 10, preventing collapse ofcavity 36 due to suction. - In some embodiments, making
vacuum shroud 10 out of flexible material may allow for compact shipping, lower shipping and manufacturing costs, as well as the other advantages discussed above, such as allowingshroud 10 to conform to various surfaces, such as curved or uneven surfaces, allowing sufficient suction throughhole 14 to remove debris and dust. For example, flexible material used to makeshroud 10 may provide a better seal to a work surface and improve the vacuum generated withincavity 36 compared to prior devices.Wall 18 or post 50 may also prevent deformation ofshroud 10 and further improve the seal and increase the vacuum withincavity 36. Forlarge holes 14,wall 18 andslots 22 may maintain a higher degree of suction withinshroud 10. These elements may work together to provideshroud 10 with high performance and utility. - In some embodiments,
shroud 10 may resist accidental movement during use as the flexible material provides greater friction than a rigid plastic in addition to the improved vacuum present in thecavity 36. This may, in some cases, allowshroud 10 to be held in place only by vacuum pressure while in use, allowing the operator to concentrate on the drilling process, or other work process throughhole 14. This may improve the quality of work being done, and may improve worker compliance and interest in usingshroud 10. - In some embodiments,
wall 18 and post 50 may be included in asingle shroud 10, providing the advantages of each in a single device. For example, the embodiment shown inFIG. 1 may include bothwall 18 and one ormore posts 50 to helpsupport shroud 10 from collapse. Likewise, the width of the slot(s) 22 (FIGS. 1 and 2 ) may be varied. Such embodiments may allowshroud 10 to be flexible while still preventing collapse of the shroud when suction is applied. - Similarly, in some embodiments,
wall 18,post 50, or both may be made of a material more rigid than other portions ofshroud 10. In such embodiments,wall 18,post 50, or both may provide structure without limiting the flexibility ofupper surface 34. Similarly,wall 18 may be removable and replaceable, allowing for differing sizes ofhole 14 or slots(s) 22 for different tools being used on the work surface. In other embodiments,shroud 10 may be made integrally, and may be made using known processes, such as vacuum molding, injection molding, casting, machining, etc. - In some embodiments,
wall 18 may have a diameter sufficiently large to observe the work surface during any work being performed on the surface. For example, if a hole is being drilled in the work surface, the hole may be sufficiently large to allow a user to view the work surface through the hole to observe the progression, position, alignment, etc, of the drill bit in the surface. For example, if a ½ inch hole is being drilled in the surface, the hole may be at least one inch to allow observation of the surface and the hole, while still allowing for the functionality ofshroud 10 as discussed above. - The present invention may be embodied in other specific forms without departing from its essential characteristics. The described embodiments are to be considered in all respects only as illustrative, and not restrictive. The scope of the invention is, therefore, indicated by the appended claims, rather than by the foregoing description. All changes within the meaning and range of equivalency of the claims are to be embraced within their scope.
