Abstract
A seismic tool assembly for effecting a drill hole and enlarging a lowermost end thereof whereby an anchor can be set more securely therein. A drill bit is inserted through an opening in a drill stop member, which is mounted on a stabilizer mounted within at least a portion of the drill hole. The bit is then inserted through each of the drill stop member and the stabilizer to attain a drilling position. The lower end of the bit has a cutting portion having a cutting radius greater than that of the bit body whereby, when the bit is inserted fully into a lowermost end of the hole and rotated, the cutting portion enlarges the lowermost end, whereby flanged portions of an anchor will rest within the enlarged area, retaining the anchor in place.
Description
SEISMIC TOOL ASSEMBLY FOR USE IN ANCHOR INSERTION
The present invention relates to a seismic tool assembly meant to be used for the later insertion and setting of anchors, such as drop-in and wedge type anchors into brittle materials such as concrete, stone, masonry and cementuous materials. More particularly, the present invention relates to a seismic tool assembly for effecting a drill hole and enlarging a lowermost end thereof to have a greater circumference than that of the remainder of the drill hole whereby an anchor can be set more securely therein.
BACKGROUND OF THE INVENTION
Anchors are conventionally used in construction to attach various components of a building construction to an overhead ceiling or other structure. Such components to be attached can relate to, for example, services that provide plumbing, electrical, drainage, sprinkler system piping and drop ceilings.
From these anchors, which are usually of the wedge or drop-in type variety, all of the above services and ceilings are suspended or secured.
Conventionally, in setting anchors in concrete to suspend an awning, for example, a hole is pre-drilled in the surface to which the anchor is to be applied, and then the anchor is inserted into the pre-drilled hole. However, when setting such anchors in concrete it is not uncommon for such anchors to weaken and loosen over time, particularly in situations where cracking or chipping of the concrete around the pre-drilled hole has occurred.
Furthermore, studies have revealed that cracking can typically occur in the concrete element, and that such cracks can significantly impact the performance of anchors. Cracks can originate on a concrete beam or slab in a variety of ways, such as creep, temperature settlement of the support or foundation, thermal expansion and contraction stress overload, or from a natural disaster such as an earthquake or flood. In such situations, the situation can arise where, if one such concrete anchor fails and lets go, the remaining anchors, by virtue of the weight they additionally assume in light of such failure, can also similarly collapse and fail.
It has been found that enlarging the lowermost (interior) portion of a drill hole can allow an anchor to be set more securely therein. It has further been found that providing a drill hole with an enlarged lower end having a greater circumference than that of the remainder of the drill hole can be advantageously provided by a drill bit having an enlarged cutting portion adjacent the tip, which is inserted into the drill hole, whereby the enlargement of the cutting portion is configured so that it can pass through the shaft of the pre-drilled hole to be enlarged.
It would therefore be advantageous to have an improved seismic tool assembly meant to be used for the later insertion and setting of anchors into brittle materials such as concrete, stone, masonry and cementuous materials.
It would be further advantageous to have an improved seismic tool assembly for use in a one step process for both creating a drill hole and, at the same time, enlarging a lowermost end of a drill hole, wherein the lowermost end of the drill hole can be further drilled and enlarged to have a greater circumference than that of the remainder of the drill hole, wherein an anchor can later be positioned and securely retained within the enlarged area.
It would also be further advantageous to have an improved seismic tool assembly meant to be used for the later insertion and setting of anchors which utilizes a stabilizer having an opening corresponding with the drill hole for receiving an insertion of the bit body into the drill hole, so as to aid in accurately inserting the drill bit into the drill hole. It would also be still further advantageous to have a stabilizer which possesses a lower end having a larger sized opening greater than that of the bit body, so as to increase the range of motion of the drilling bit and permit limited tilting movement of the bit within the stabilizer during the drilling process so as to further aid in enlarging a lowermost end of the drill hole to receive an anchor. To this end, the present invention effectively addresses this need.

DETAILED DESCRIPTION OF THE INVENTION
The invention will be described for the purposes of illustration only in connection with certain embodiments;
however, it is to be understood that other objects and advantages of the present invention will be made apparent by the following description of the drawings according to the present invention.
While a preferred embodiment is disclosed, this is not intended to be limiting. Rather, the general principles set forth herein are considered to be merely illustrative of the scope of the present invention and it is to be further understood that numerous changes may be made without straying from the scope of the present invention.
The present invention consists of an improved seismic tool assembly designed for effecting a drill hole and enlarging a lowermost end thereof to have a greater circumference than that of the remainder of the drill hole whereby an anchor can be set more securely therein.
Referring to Figure 1, there is shown a seismic tool assembly for use in the later insertion and setting of anchors shown generally at 1 in accordance with a first exemplary embodiment of the present invention. In a preferred embodiment, as hereinafter described, the seismic tool assembly 1 is to be rotatably mounted onto a drill by way of a drill spindle (not shown). It will be understood that there are numerous variations as to the types of attachments to a drill or otherwise that the seismic tool assembly 1 of the present invention could be mounted thereon, as would be readily apparent to one skilled in the art.
In a preferred embodiment, the seismic tool assembly 1 is for use in the later insertion and setting of anchors into concrete, stone, masonry and cementuous materials (though it will be understood that other variations to this are possible) and comprises a seismic drilling bit 2, a stabilizer 7, and a drill stop member 5, as hereinafter described.
Preferably, the components of the assembly, including the seismic drilling bit 2, stabilizer 7, and drill stop member 5, will be made of a durable, machinable metal. The seismic drilling bit 2 is, preferably, substantially cylindrical in shape and is of a one-piece construction that comprises an upper end 6 and a lower end 8 which are integrally connected to one another.
With reference to Figure 1, it can be seen that the bit body 4 of the seismic drilling bit 2 can effect the drilling of a drill hole, and has a first diameter (and cutting radius) sized to readily fit into a drill hole (not shown), and possesses, as most conventional drill bits do, at least one cutting edge and at least one groove extending in a helical fashion along a length of the bit body 4 of the seismic drilling bit 2. In a preferred embodiment, these extend along a substantial length of the bit body 4, or, alternatively, extend along at least half a length of the bit body 4. Preferably, the first diameter of the upper end 6 of the bit body 4 is less than or equal to a diameter of the drill hole into which the seismic drilling bit 2 of the present invention is to be inserted.
The upper end 6 of the seismic drilling bit 2 is constructed and arranged to be releasably secured to a drill by way of a drill spindle (not shown). In an exemplary embodiment, the distal lower end 8 of the seismic drilling bit 2 has a drill tip 11 extending generally outwardly from the lower end 8.
The lower end 8 of the seismic drilling bit 2 has a cutting portion 10 positioned on each side of the lower end 8 of the seismic drilling bit 2, the cutting portions 10 having a greater outermost width than that of the bit body 4 whereby, when the seismic drilling bit 2 is inserted fully into a lowermost end of the drill hole and rotated, so as to effect a conical shape in the drill hole, the cutting portions 10 enlarge a circumference of the drill hole at the lowermost end thereof that is greater than the circumference of the remainder of the shaft of the drill hole. Preferably, the cutting portions 10 extend outwardly from substantially around an entirety of the lower end 8 of the seismic drilling bit 2, as seen in Figure 1. In an alternative embodiment (which is not shown), the lower end 8 of the seismic drilling bit 2 can have a cutting portion positioned on only one side of the lower end 8 of the seismic drilling bit 2.
In a still further embodiment (not shown), the bit body 4 of the seismic drilling bit 2 has a diameter (and cutting radius) that is less than that of the drill hole, with the cutting portions 10, of course, still having a greater outermost width (and cutting radius) than that of the bit body 4. In this manner, with the bit body 4 of the seismic drilling bit 2 having a width that is less than that of the drill hole, the initial insertion of the seismic drilling bit 2 into the drill hole is made easier, whereby the bit does not need to be as readily forcibly inserted.
With reference to Figure 4, the drill stop member 5, preferably, has an opening 12 defined therethrough, and is used for receiving an insertion of the seismic drilling bit 2.
Preferably, the opening in the drill stop member 5 is positioned at a substantially central location of the drill stop member S.
The drill stop member 5 aids in the accurate and gradual insertion of the seismic drilling bit 2 into the drill hole. The drill stop member 5 further comprises, with reference to Figures 4 and 5, a dust exit opening 3 defined therein for allowing dust to be removed from the assembly during the drilling process, the dust exit opening 3 being positioned at substantially a middle portion of the drill stop member 5. It will, of course, also be understood that the stabilizer 7 could also possess such a dust exit opening.
The seismic tool assembly 1 further comprises, with reference to Figure 1, a stabilizer 7 for receiving, and having mounted thereon, the drill stop member 5. The stabilizer 7 comprises a flange portion 15 constructed and arranged to extend into the drill hole and abut an inside portion thereof. In an alternative embodiment (not shown), the flange portion 15 of the stabilizer 7 could be tapered at a distal end thereof so as to further aid in the accurate and gradual insertion of the seismic drilling bit 2 into the drill hole. It will of course be understood that the dimensions of the stabilizer 7, or indeed of any of the components of the assembly 1 could be varied, depending upon the size of the drill bit to be used. In an exemplary embodiment, the stabilizer 7, with reference to Figure 2, has a central opening 9 which corresponds with each of the openings of the drill stop member 5 and the drill hole. The flange portion 15 when drilling acts also to stabilize the drill hole, as the flange portion 15 is bigger that the borehole, and, when forced inside when drilling, it becomes a controlled and secure tilted rotation as it jams up the borehole.
The opening 9 on the stabilizer 7 has a diameter larger than the cutting portions 10 of the bit body 4. By virtue of the opening 9 being greater than the cutting portions 10 of the bit body 4 to accommodates passage therethrough, this allows the insertion of the seismic drilling bit 2 into the drill hole (not shown), and permits a controlled limited tilting movement of the bit body 4 from its vertical axis within the opening 9 (and allows for less physical contact with, particularly, the flange portion 15) on the stabilizer 7 during the drilling process to further enlarge a lowermost end of the drill hole, it being understood that this controlled tilting rotational drilling of the lower end of the drill hole by the drill bit 2 within the opening 9 can be done through 360 degrees, whereby the lower end of the drill hole can be made to be conical and funnel-shaped, for receiving anchors therein. It will also be understood that to reduce or increase the conical effect of the bore hole the drill stop member 5 can be machined to be smaller or bigger, as required. Further, the drill stop member 5 can be interchanged to accommodate different drilling depths and sizes of drill bits.
The stabilizer 7 further comprises, as shown in Figures 2 and 3, the stabilizer 7 is comprised of a lower portion 95 and a securing portion 96, which possesses threads 97 towards a lowermost end thereof. In an exemplary embodiment, each of the lower portion 95 and a securing portion 96 comprise openings therethrough which corresponds with each of the openings of the drill stop member 5 and the drill hole. In positioning the drill stop member 5 within the assembly, an upper end 99 of the drill stop member 5 is passed through an opening in the securing portion 96, and a lower end 100 is then positioned within the lower portion 95, the lower end 100 resting on abutment region 101. The lower end 100 of drill stop member 5, possesses a greater width than a remainder of the drill stop member 5 and, when in place, abuts abutment region 101 so as to inhibit the downward movement of drill stop member 5 within the lower portion 95. To secure the drill stop member 5 in place, the lower portion 95 possesses threads on an interior surface thereof 98 which can be matingly engaged with the threads 97 of securing portion 96 so as to secure the lower portion 95 to the securing portion 96, and each of the lower portion 95 and securing portion 96 have an outermost width that is greater than that of the drill stop member 5. In this manner, once the lower portion 95 and securing portion 96 are secured together, the lower portion 95 and securing portion 96 hold the lower end 100 of the drill stop member 5 firmly in place within the assembly.
To secure the upper end of the assembly 1 in place, as shown in Figures 1, 2, 3 and 4, the drill stop member 5 itself possesses threads 90 towards an uppermost end 99 thereof. The drill stop member 5 further comprises an upper portion 91. This upper portion 91, also possesses threads 103 on an interior surface thereof (shown in Figure 7) which can be matingly engaged with the threads 90 on uppermost end 99 of the drill stop member so as to secure the upper portion 91 to the drill stop member 5, though of course variations to this are possible.
In turn, as shown in Figures 6 and 7, the upper portion 91 also possesses threads 92 towards an uppermost end thereof, which can be matingly engaged with cap portion 93, which also possesses threads 105 on an interior surface thereof. The cap portion 93 and upper portion 91 will, in an exemplary embodiment, each have an opening defined therethrough (not shown) for receiving an insertion of the bit body 4 therethrough, which corresponds with the central openings of the stabilizer 7 and the drill stop member 5. In this manner, once upper portion 91 is connected to the drill stop member 5, and the cap portion 93 is also secured to the opposite end of upper portion 91, these hold the upper end of the drill stop member 5 firmly in place within the assembly.
When disengagement of the upper portion 91 and cap portion 93 is desired, the threaded portions of each can be untightened so as to permit the disengagement of components from the drill stop member 5.
Figures 6 and 7 illustrate the seismic drill bit 2 having abutment member 109 thereon, and the assembly further comprising restrictive disk 107, the restrictive disk 107 being operably able to be positioned within an upper end of the upper portion 91, and to cover substantially the upper end of the upper portion 91. In an exemplary embodiment, the restrictive disk 107 has a shape which corresponds substantially to a shape of the cutting portions 10 of the seismic drill bit 2 for receiving the insertion of the seismic drill bit 2 therethrough.
When the seismic drill bit 2 is inserted through the upper end of the upper portion 91, the restrictive disk 107 restricts downward movement of the seismic drilling bit 2 to a pre-set depth, through virtue of the seismic drilling bit 2 only being able to be pushed downwardly within the upper portion 91 to a certain point, at which abutment member 109 it comes into contact with the restrictive disk 107, thus restricting downward movement of the seismic drilling bit 2.
In operation, the seismic drill bit 2 is inserted through the upper end of the upper portion 91, whereby the restrictive disk 107 restricts downward movement of the seismic drilling bit 2 to a pre-set depth, through virtue of the seismic drilling bit 2 only being able to be pushed downwardly within the upper portion 91 to a certain point, at which abutment member 109 comes into contact with the restrictive disk 107 within an upper end of the upper portion 91, thus restricting downward movement of the seismic drilling bit 2.
An upper end 99 of the drill stop member 5 is then passed through an opening in the securing portion 96, and a lower end 100 is then positioned within the lower portion 95, the lower end 100 resting on abutment region 101. The lower end 100 of drill stop member 5, when in place, abuts abutment region 101 so as to inhibit the downward movement of drill stop member 5 within the lower portion 95. Once this is done the seismic drilling bit 2 is then inserted downwardly through the openings in each of the securing portion 96, the drill stop member 5 and the lower portion 95. Of course, the lower end 8 of the seismic drilling bit 2 emerges through opening 114 in the lower portion 95.
To secure the drill stop member 5 in place, and the lower end of the assembly 1 in place, the lower portion 95 possesses threads on an interior surface thereof 98 which can be matingly engaged with the threads 97 of securing portion 96 so as to secure the lower portion 95 to the securing portion 96, and each of the lower portion 95 and securing portion 96 have an outermost width that is greater than that of the drill stop member 5. In this manner, once the lower portion 95 and securing portion 96 are secured together, the lower portion 95 and securing portion 96 hold the lower end 100 of the drill stop member 5 firmly in place within the assembly.
To secure the upper end of the assembly 1 in place the threads 90 of the drill stop member 5 are matingly engaged with the threads 103 of the upper portion 91. The upper end 6 of the seismic drilling bit 2 is then inserted through the opening in the cap portion 93, and the cap portion is then moved downwardly, whereby the threads 92 of the upper portion 91 can be matingly engaged with the threads 105 on an interior surface of the cap portion 93 to secure the upper half the assembly. The drilling process is then begun, in a one-step process, whereby the drill hole is first created, then, as downward pressure is continued, the flange portion 15 of the stabilizer 7 is pushed to extend into the drill hole and abut an inside portion thereof. In this manner, the flange portion 15 stabilizes the seismic tool assembly 1 during the drilling process. Once the seismic drilling bit 2 is sunk to a pre-set depth and rotated, rotational drilling (and tilted rotational drilling as previously described) by the seismic drilling bit 2 can then be effected in creating an enlarged area of the lowermost end of a drill hole.
Of course, by virtue of the cutting portions 10 having an outermost width (and operational cutting radius) that is slightly greater than that of the bit body 4, these cutting portions 10, when the seismic drilling bit 2 is rotated, enlarge a circumference of the drill hole at the lowermost end (in creating the enlarged area) that is greater than that of the remainder of the drill hole. In this manner, once the enlarged area has been created, and the seismic drilling bit 2 removed from the drill hole, the anchor (not shown) can be inserted, and, when the anchors have been flanged outwardly by conventional means within the drill hole, the flange portions of the anchor can rest within the enlarged area, thus securely retaining the anchor in place.
In a still further alternative embodiment of the fully connected seismic tool assembly, shown in Figures 8 to 13, there is shown a seismic tool assembly for use in the later insertion and setting of anchors shown generally at 1 in accordance with a first exemplary embodiment of the present invention. As previously described with other embodiments, the seismic tool assembly 1, as shown in Figure 9, is to be rotatably mounted onto a drill by way of a drill spindle (not shown).
In a preferred embodiment, this embodiment of the seismic tool assembly 1 is for use in the later insertion and setting of anchors into concrete, stone, masonry and cementuous materials (though it will be understood that other variations to this are possible) and comprises a seismic drilling bit 2, a stabilizer 7, a drill stop member 5 and a cap portion 93, as hereinafter described.
Preferably, the components of the assembly, including the seismic drilling bit 2 (see Figure 9), stabilizer 7 (see Figure 11), and drill stop member 5 (see Figure 8), will be made of a durable, machinable metal. The seismic drilling bit 2 is, preferably, substantially cylindrical in shape and is of a one-piece construction that comprises an upper end 6 and a lower end 8 which are integrally connected to one another.
With reference to Figure 8, it can be seen that the bit body 4 of the seismic drilling bit 2 can effect the drilling of a drill hole, and has a first diameter (and cutting radius) sized to readily fit into a drill hole (not shown), and possesses, as most conventional drill bits do, at least one cutting edge and at least one groove extending in a helical fashion along a length of the bit body 4 of the seismic drilling bit 2. In a preferred embodiment, these extend along a substantial length of the bit body 4, or, alternatively, extend along at least half a length of the bit body 4. Preferably, the first diameter of the upper end 6 of the bit body 4 is less than or equal to a diameter of the drill hole into which the seismic drilling bit 2 of the present invention is to be inserted.
The upper end 6 of the seismic drilling bit 2, with reference to Figure 9, is constructed and arranged to be releasably secured to a drill by way of a drill spindle (not shown). In an exemplary embodiment, the distal lower end 8 of the seismic drilling bit 2 has a drill tip 11 extending generally outwardly from the lower end 8.
The lower end 8 of the seismic drilling bit 2 has a cutting portion 10 positioned on each side of the lower end 8 of the seismic drilling bit 2, the cutting portions 10 having a greater outermost width than that of the bit body 4 whereby, when the seismic drilling bit 2 is inserted fully into a lowermost end of the drill hole and rotated, the cutting portions 10 enlarge a circumference of the drill hole at the lowermost end thereof that is greater than the circumference of the remainder of the shaft of the drill hole. Preferably, the cutting portions 10 extend outwardly from substantially around an entirety of the lower end 8 of the seismic drilling bit 2, as seen in Figure 9. In an alternative embodiment (which is not shown), the lower end 8 of the seismic drilling bit 2 can have a cutting portion positioned on only one side of the lower end 8 of the seismic drilling bit 2.
In a still further embodiment (not shown), the bit body 4 of the seismic drilling bit 2 has a diameter (and cutting radius) that is less than that of the drill hole, with the cutting portions 10, of course, still having a greater outermost width (and cutting radius) than that of the bit body 4. In this manner, with the bit body 4 of the seismic drilling bit 2 having a width that is less than that of the drill hole, the initial insertion of the seismic drilling bit 2 into the drill hole is made easier, whereby the bit does not need to be as readily forcibly inserted.
With reference to Figure 10, the drill stop member 5, preferably, has an opening 112 defined therethrough, and is used for receiving an insertion of the seismic drilling bit 2.
Preferably, the opening 112 in the drill stop member 5 is positioned at a substantially central location of the drill stop member 5. The drill stop member 5 aids in the accurate and gradual insertion of the seismic drilling bit 2 into the drill hole. The drill stop member 5 further comprises, with reference to Figure 11, a dust exit opening 3 defined therein for allowing dust to be removed from the assembly during the drilling process, the dust exit opening 3 being positioned at substantially a middle portion of the drill stop member 5. It will, of course, also be understood that the stabilizer 7 could also possess such a dust exit opening.
The seismic tool assembly 1 further comprises, with reference to Figures 8 to 13, a stabilizer 7 for receiving, and having mounted thereon, the drill stop member S. The stabilizer 7 comprises a flange portion 15 constructed and arranged to extend into the drill hole and abut an inside portion thereof. In an alternative embodiment (not shown), the flange portion 15 of the stabilizer 7 could be tapered at a distal end thereof so as to further aid in the accurate and gradual insertion of the seismic drilling bit 2 into the drill hole. It will of course be understood that the dimensions of the stabilizer 7, or indeed of any of the components of the assembly 1 could be varied, depending upon the size of the drill bit to be used. In an exemplary embodiment, the stabilizer 7, with reference to Figure 11, has a central opening 114 which corresponds with each of the openings of the drill stop member 5 and the drill hole.
With further reference to Figure 11, it can be seen that the opening 114 on the stabilizer 7 has a diameter larger than the cutting portions 10 of the bit body 4. By virtue of the opening 114 being greater than the cutting portions 10 of the bit body 4 to accommodates passage therethrough, this allows the insertion of the seismic drilling bit 2 into the drill hole (not shown), and permits limited tilting movement of the bit body 4 from its vertical axis within the opening 114 (and allows for less physical contact with, particularly, the flange portion 15) on the stabilizer 7 during the drilling process to further enlarge a lowermost end of the drill hole, it being understood that this tilting rotational drilling of the lower end of the drill hole by the drill bit 2 within the opening 114 can be done through 360 degrees, whereby the lower end of the drill hole can be made to be conical and funnel-shaped, for receiving anchors therein.
The stabilizer 7 further comprises, as shown in Figure 10 and 11, the stabilizer 7 is comprised of a lower portion 95 and a securing portion 96, which possesses threads 97 towards a lowermost end thereof. In an exemplary embodiment, each of the lower portion 95 and a securing portion 96 comprise openings therethrough which corresponds with each of the openings of the drill stop member 5 and the drill hole. In positioning the drill stop member 5 within the assembly, an upper end 99 of the drill stop member 5 is passed through an opening in the securing portion 96, and a lower end 100 of the drill stop member 5 is then positioned within the lower portion 95, the lower end 100 resting on abutment region 101. The lower end 100 of drill stop member 5, when in place, abuts abutment region 101 so as to inhibit the downward movement of drill stop member 5 within the lower portion 95. To secure the drill stop member 5 in place, the lower portion 95 possesses threads on an interior surface thereof 98 which can be matingly engaged with the threads 97 of securing portion 96 so as to secure the lower portion 95 to the securing portion 96, and each of the lower portion 95 and securing portion 96 have an outermost width that is greater than that of the drill stop member S. In this manner, once the lower portion 95 and securing portion 96 are secured together, the lower portion 95 and securing portion 96 hold the lower end 100 of the drill stop member 5 firmly in place within the assembly.
Figures 9, 10 and 12 illustrate the seismic drill bit 2 having abutment member 109 thereon, the abutment member 109 having a greater width than a remainder of the seismic drill bit 2. When the seismic drill bit 2 is inserted through the uppermost end 99 of the drill stop member 5, and as the seismic drill bit 2 continues to be inserted therethrough, abutment member 109 on the seismic drilling bit 2 eventually comes into contact with the uppermost end 99 of the drill stop member 5, thus restricting downward movement of the seismic drilling bit 2 to a pre-set depth.
To secure the upper end of the assembly 1 in place, as shown in Figures 12 and 13, the drill stop member 5 itself possesses threads 90 towards an uppermost end 99 thereof, which can be matingly engaged with cap portion 93, which also possesses threads 105 on an interior surface thereof. The cap portion 93, as shown in Figure 9, will, in an exemplary embodiment, have an opening 124 (see Figure 9) defined therethrough for receiving an insertion of the seismic drill bit 2 therethrough, which corresponds with the central openings of the stabilizer 7 and the drill stop member S. The cap portion 93 is positioned over the distal end 6 of the seismic drilling bit 2, and the cap portion 93 is then moved downwardly to cover and surround a substantial middle portion of the seismic drilling bit 2, whereby the threads 105 on an interior surface of the cap portion 93 (see Figure 9) can then be matingly engaged with the threads 90 of the drill stop member 5 to secure the upper half the assembly. When disengagement of the drill stop member 5 and cap portion 93 is desired, the threaded portions of each can be untightened so as to permit the disengagement of components.
In operation the seismic drill bit 2 is inserted through the uppermost end 99 of the drill stop member 5, whereby, as seismic drill bit 2 continues to be inserted therethrough, abutment member 109 on the seismic drilling bit 2 comes into contact with the uppermost end 99 of the drill stop member 5, thus restricting downward movement of the seismic drilling bit 2 to a pre-set depth, see Figures 10 and 12, which illustrates that the uppermost end 99 of the drill stop member 5 and the abutment member 109 on the seismic drilling bit 2 have a width that is substantially equal.
A lower end 100 of the drill stop member 5 is then positioned within the lower portion 95, the lower end 100 resting on abutment region 101. The lower end 100 of drill stop member 5, when in place, abuts abutment region 101 so as to inhibit the downward movement of drill stop member 5 within the lower portion 95. Once this is done the seismic drilling bit 2 is then inserted downwardly through the openings in each of the securing portion 96, the drill stop member 5 and the lower portion 95. Of course, the lower end 8 of the seismic drilling bit 2 emerges through opening 114 in the lower portion 95.
To secure the drill stop member 5 in place, and the lower end of the assembly 1 in place, the lower portion 95 possesses threads on an interior surface thereof 98 which can be matingly engaged with the threads 97 of securing portion 96 so as to secure the lower portion 95 to the securing portion 96, and each of the lower portion 95 and securing portion 96 have an outermost width that is greater than that of the drill stop member 5. In this manner, once the lower portion 95 and securing portion 96 are secured together, the lower portion 95 and securing portion 96 hold the lower end 100 of the drill stop member 5 firmly in place within the assembly, as shown in Figure 12.
To secure the upper end of the assembly 1 in place, a cap portion 93 having an opening defined therethrough is positioned over the distal end 6 of the seismic drilling bit 2, and the cap portion 93 is then moved downwardly to cover and surround a substantial middle portion of the seismic drilling bit, whereby the threads 105 on an interior surface of the cap portion 93 (see Figure 9) can be matingly engaged with the threads 90 of the drill stop member 5 to secure the upper half the assembly, as shown in Figure 12. The drilling process is then begun, in a one-step process, whereby the drill hole is first created, then, as downward pressure is continued, the flange portion 15 of the stabilizer 7 is pushed to extend into the drill hole and abut an inside portion thereof. In this manner, the flange portion 15 stabilizes the seismic tool assembly 1 during the drilling process. Once the seismic drilling bit 2 is sunk to a pre-set depth and rotated, rotational drilling (and tilted rotational drilling as previously described) by the seismic drilling bit 2 can then be effected in creating an enlarged area of the lowermost end of a drill hole.
Of course, by virtue of the cutting portions 10 having an outermost width (and operational cutting radius) that is slightly greater than that of the bit body 4, these cutting portions 10, when the seismic drilling bit 2 is rotated, enlarge a circumference of the drill hole at the lowermost end (in creating the enlarged area) that is greater than that of the remainder of the drill hole. In this manner, once the enlarged area has been created, and the seismic drilling bit 2 removed from the drill hole, the anchor (not shown) can be inserted, and, when the anchors have been flanged outwardly by conventional means within the drill hole, the flange portions of the anchor can rest within the enlarged area, thus securely retaining the anchor in place.
It will be apparent to those skilled in this art that various modifications and variations may be made to the embodiments disclosed herein, consistent with the present invention, without departing from the spirit and scope of the present invention.
Other embodiments consistent with the present invention will become apparent from consideration of the specification and the practice of the invention disclosed therein.
Accordingly, the specification and the embodiments are to be considered exemplary only, with a true scope and spirit of the invention being disclosed by the following claims.
The present invention relates to a seismic tool assembly meant to be used for the later insertion and setting of anchors, such as drop-in and wedge type anchors into brittle materials such as concrete, stone, masonry and cementuous materials. More particularly, the present invention relates to a seismic tool assembly for effecting a drill hole and enlarging a lowermost end thereof to have a greater circumference than that of the remainder of the drill hole whereby an anchor can be set more securely therein.
BACKGROUND OF THE INVENTION
Anchors are conventionally used in construction to attach various components of a building construction to an overhead ceiling or other structure. Such components to be attached can relate to, for example, services that provide plumbing, electrical, drainage, sprinkler system piping and drop ceilings.
From these anchors, which are usually of the wedge or drop-in type variety, all of the above services and ceilings are suspended or secured.
Conventionally, in setting anchors in concrete to suspend an awning, for example, a hole is pre-drilled in the surface to which the anchor is to be applied, and then the anchor is inserted into the pre-drilled hole. However, when setting such anchors in concrete it is not uncommon for such anchors to weaken and loosen over time, particularly in situations where cracking or chipping of the concrete around the pre-drilled hole has occurred.
Furthermore, studies have revealed that cracking can typically occur in the concrete element, and that such cracks can significantly impact the performance of anchors. Cracks can originate on a concrete beam or slab in a variety of ways, such as creep, temperature settlement of the support or foundation, thermal expansion and contraction stress overload, or from a natural disaster such as an earthquake or flood. In such situations, the situation can arise where, if one such concrete anchor fails and lets go, the remaining anchors, by virtue of the weight they additionally assume in light of such failure, can also similarly collapse and fail.
It has been found that enlarging the lowermost (interior) portion of a drill hole can allow an anchor to be set more securely therein. It has further been found that providing a drill hole with an enlarged lower end having a greater circumference than that of the remainder of the drill hole can be advantageously provided by a drill bit having an enlarged cutting portion adjacent the tip, which is inserted into the drill hole, whereby the enlargement of the cutting portion is configured so that it can pass through the shaft of the pre-drilled hole to be enlarged.
It would therefore be advantageous to have an improved seismic tool assembly meant to be used for the later insertion and setting of anchors into brittle materials such as concrete, stone, masonry and cementuous materials.
It would be further advantageous to have an improved seismic tool assembly for use in a one step process for both creating a drill hole and, at the same time, enlarging a lowermost end of a drill hole, wherein the lowermost end of the drill hole can be further drilled and enlarged to have a greater circumference than that of the remainder of the drill hole, wherein an anchor can later be positioned and securely retained within the enlarged area.
It would also be further advantageous to have an improved seismic tool assembly meant to be used for the later insertion and setting of anchors which utilizes a stabilizer having an opening corresponding with the drill hole for receiving an insertion of the bit body into the drill hole, so as to aid in accurately inserting the drill bit into the drill hole. It would also be still further advantageous to have a stabilizer which possesses a lower end having a larger sized opening greater than that of the bit body, so as to increase the range of motion of the drilling bit and permit limited tilting movement of the bit within the stabilizer during the drilling process so as to further aid in enlarging a lowermost end of the drill hole to receive an anchor. To this end, the present invention effectively addresses this need.

DETAILED DESCRIPTION OF THE INVENTION
The invention will be described for the purposes of illustration only in connection with certain embodiments;
however, it is to be understood that other objects and advantages of the present invention will be made apparent by the following description of the drawings according to the present invention.
While a preferred embodiment is disclosed, this is not intended to be limiting. Rather, the general principles set forth herein are considered to be merely illustrative of the scope of the present invention and it is to be further understood that numerous changes may be made without straying from the scope of the present invention.
The present invention consists of an improved seismic tool assembly designed for effecting a drill hole and enlarging a lowermost end thereof to have a greater circumference than that of the remainder of the drill hole whereby an anchor can be set more securely therein.
Referring to Figure 1, there is shown a seismic tool assembly for use in the later insertion and setting of anchors shown generally at 1 in accordance with a first exemplary embodiment of the present invention. In a preferred embodiment, as hereinafter described, the seismic tool assembly 1 is to be rotatably mounted onto a drill by way of a drill spindle (not shown). It will be understood that there are numerous variations as to the types of attachments to a drill or otherwise that the seismic tool assembly 1 of the present invention could be mounted thereon, as would be readily apparent to one skilled in the art.
In a preferred embodiment, the seismic tool assembly 1 is for use in the later insertion and setting of anchors into concrete, stone, masonry and cementuous materials (though it will be understood that other variations to this are possible) and comprises a seismic drilling bit 2, a stabilizer 7, and a drill stop member 5, as hereinafter described.
Preferably, the components of the assembly, including the seismic drilling bit 2, stabilizer 7, and drill stop member 5, will be made of a durable, machinable metal. The seismic drilling bit 2 is, preferably, substantially cylindrical in shape and is of a one-piece construction that comprises an upper end 6 and a lower end 8 which are integrally connected to one another.
With reference to Figure 1, it can be seen that the bit body 4 of the seismic drilling bit 2 can effect the drilling of a drill hole, and has a first diameter (and cutting radius) sized to readily fit into a drill hole (not shown), and possesses, as most conventional drill bits do, at least one cutting edge and at least one groove extending in a helical fashion along a length of the bit body 4 of the seismic drilling bit 2. In a preferred embodiment, these extend along a substantial length of the bit body 4, or, alternatively, extend along at least half a length of the bit body 4. Preferably, the first diameter of the upper end 6 of the bit body 4 is less than or equal to a diameter of the drill hole into which the seismic drilling bit 2 of the present invention is to be inserted.
The upper end 6 of the seismic drilling bit 2 is constructed and arranged to be releasably secured to a drill by way of a drill spindle (not shown). In an exemplary embodiment, the distal lower end 8 of the seismic drilling bit 2 has a drill tip 11 extending generally outwardly from the lower end 8.
The lower end 8 of the seismic drilling bit 2 has a cutting portion 10 positioned on each side of the lower end 8 of the seismic drilling bit 2, the cutting portions 10 having a greater outermost width than that of the bit body 4 whereby, when the seismic drilling bit 2 is inserted fully into a lowermost end of the drill hole and rotated, so as to effect a conical shape in the drill hole, the cutting portions 10 enlarge a circumference of the drill hole at the lowermost end thereof that is greater than the circumference of the remainder of the shaft of the drill hole. Preferably, the cutting portions 10 extend outwardly from substantially around an entirety of the lower end 8 of the seismic drilling bit 2, as seen in Figure 1. In an alternative embodiment (which is not shown), the lower end 8 of the seismic drilling bit 2 can have a cutting portion positioned on only one side of the lower end 8 of the seismic drilling bit 2.
In a still further embodiment (not shown), the bit body 4 of the seismic drilling bit 2 has a diameter (and cutting radius) that is less than that of the drill hole, with the cutting portions 10, of course, still having a greater outermost width (and cutting radius) than that of the bit body 4. In this manner, with the bit body 4 of the seismic drilling bit 2 having a width that is less than that of the drill hole, the initial insertion of the seismic drilling bit 2 into the drill hole is made easier, whereby the bit does not need to be as readily forcibly inserted.
With reference to Figure 4, the drill stop member 5, preferably, has an opening 12 defined therethrough, and is used for receiving an insertion of the seismic drilling bit 2.
Preferably, the opening in the drill stop member 5 is positioned at a substantially central location of the drill stop member S.
The drill stop member 5 aids in the accurate and gradual insertion of the seismic drilling bit 2 into the drill hole. The drill stop member 5 further comprises, with reference to Figures 4 and 5, a dust exit opening 3 defined therein for allowing dust to be removed from the assembly during the drilling process, the dust exit opening 3 being positioned at substantially a middle portion of the drill stop member 5. It will, of course, also be understood that the stabilizer 7 could also possess such a dust exit opening.
The seismic tool assembly 1 further comprises, with reference to Figure 1, a stabilizer 7 for receiving, and having mounted thereon, the drill stop member 5. The stabilizer 7 comprises a flange portion 15 constructed and arranged to extend into the drill hole and abut an inside portion thereof. In an alternative embodiment (not shown), the flange portion 15 of the stabilizer 7 could be tapered at a distal end thereof so as to further aid in the accurate and gradual insertion of the seismic drilling bit 2 into the drill hole. It will of course be understood that the dimensions of the stabilizer 7, or indeed of any of the components of the assembly 1 could be varied, depending upon the size of the drill bit to be used. In an exemplary embodiment, the stabilizer 7, with reference to Figure 2, has a central opening 9 which corresponds with each of the openings of the drill stop member 5 and the drill hole. The flange portion 15 when drilling acts also to stabilize the drill hole, as the flange portion 15 is bigger that the borehole, and, when forced inside when drilling, it becomes a controlled and secure tilted rotation as it jams up the borehole.
The opening 9 on the stabilizer 7 has a diameter larger than the cutting portions 10 of the bit body 4. By virtue of the opening 9 being greater than the cutting portions 10 of the bit body 4 to accommodates passage therethrough, this allows the insertion of the seismic drilling bit 2 into the drill hole (not shown), and permits a controlled limited tilting movement of the bit body 4 from its vertical axis within the opening 9 (and allows for less physical contact with, particularly, the flange portion 15) on the stabilizer 7 during the drilling process to further enlarge a lowermost end of the drill hole, it being understood that this controlled tilting rotational drilling of the lower end of the drill hole by the drill bit 2 within the opening 9 can be done through 360 degrees, whereby the lower end of the drill hole can be made to be conical and funnel-shaped, for receiving anchors therein. It will also be understood that to reduce or increase the conical effect of the bore hole the drill stop member 5 can be machined to be smaller or bigger, as required. Further, the drill stop member 5 can be interchanged to accommodate different drilling depths and sizes of drill bits.
The stabilizer 7 further comprises, as shown in Figures 2 and 3, the stabilizer 7 is comprised of a lower portion 95 and a securing portion 96, which possesses threads 97 towards a lowermost end thereof. In an exemplary embodiment, each of the lower portion 95 and a securing portion 96 comprise openings therethrough which corresponds with each of the openings of the drill stop member 5 and the drill hole. In positioning the drill stop member 5 within the assembly, an upper end 99 of the drill stop member 5 is passed through an opening in the securing portion 96, and a lower end 100 is then positioned within the lower portion 95, the lower end 100 resting on abutment region 101. The lower end 100 of drill stop member 5, possesses a greater width than a remainder of the drill stop member 5 and, when in place, abuts abutment region 101 so as to inhibit the downward movement of drill stop member 5 within the lower portion 95. To secure the drill stop member 5 in place, the lower portion 95 possesses threads on an interior surface thereof 98 which can be matingly engaged with the threads 97 of securing portion 96 so as to secure the lower portion 95 to the securing portion 96, and each of the lower portion 95 and securing portion 96 have an outermost width that is greater than that of the drill stop member 5. In this manner, once the lower portion 95 and securing portion 96 are secured together, the lower portion 95 and securing portion 96 hold the lower end 100 of the drill stop member 5 firmly in place within the assembly.
To secure the upper end of the assembly 1 in place, as shown in Figures 1, 2, 3 and 4, the drill stop member 5 itself possesses threads 90 towards an uppermost end 99 thereof. The drill stop member 5 further comprises an upper portion 91. This upper portion 91, also possesses threads 103 on an interior surface thereof (shown in Figure 7) which can be matingly engaged with the threads 90 on uppermost end 99 of the drill stop member so as to secure the upper portion 91 to the drill stop member 5, though of course variations to this are possible.
In turn, as shown in Figures 6 and 7, the upper portion 91 also possesses threads 92 towards an uppermost end thereof, which can be matingly engaged with cap portion 93, which also possesses threads 105 on an interior surface thereof. The cap portion 93 and upper portion 91 will, in an exemplary embodiment, each have an opening defined therethrough (not shown) for receiving an insertion of the bit body 4 therethrough, which corresponds with the central openings of the stabilizer 7 and the drill stop member 5. In this manner, once upper portion 91 is connected to the drill stop member 5, and the cap portion 93 is also secured to the opposite end of upper portion 91, these hold the upper end of the drill stop member 5 firmly in place within the assembly.
When disengagement of the upper portion 91 and cap portion 93 is desired, the threaded portions of each can be untightened so as to permit the disengagement of components from the drill stop member 5.
Figures 6 and 7 illustrate the seismic drill bit 2 having abutment member 109 thereon, and the assembly further comprising restrictive disk 107, the restrictive disk 107 being operably able to be positioned within an upper end of the upper portion 91, and to cover substantially the upper end of the upper portion 91. In an exemplary embodiment, the restrictive disk 107 has a shape which corresponds substantially to a shape of the cutting portions 10 of the seismic drill bit 2 for receiving the insertion of the seismic drill bit 2 therethrough.
When the seismic drill bit 2 is inserted through the upper end of the upper portion 91, the restrictive disk 107 restricts downward movement of the seismic drilling bit 2 to a pre-set depth, through virtue of the seismic drilling bit 2 only being able to be pushed downwardly within the upper portion 91 to a certain point, at which abutment member 109 it comes into contact with the restrictive disk 107, thus restricting downward movement of the seismic drilling bit 2.
In operation, the seismic drill bit 2 is inserted through the upper end of the upper portion 91, whereby the restrictive disk 107 restricts downward movement of the seismic drilling bit 2 to a pre-set depth, through virtue of the seismic drilling bit 2 only being able to be pushed downwardly within the upper portion 91 to a certain point, at which abutment member 109 comes into contact with the restrictive disk 107 within an upper end of the upper portion 91, thus restricting downward movement of the seismic drilling bit 2.
An upper end 99 of the drill stop member 5 is then passed through an opening in the securing portion 96, and a lower end 100 is then positioned within the lower portion 95, the lower end 100 resting on abutment region 101. The lower end 100 of drill stop member 5, when in place, abuts abutment region 101 so as to inhibit the downward movement of drill stop member 5 within the lower portion 95. Once this is done the seismic drilling bit 2 is then inserted downwardly through the openings in each of the securing portion 96, the drill stop member 5 and the lower portion 95. Of course, the lower end 8 of the seismic drilling bit 2 emerges through opening 114 in the lower portion 95.
To secure the drill stop member 5 in place, and the lower end of the assembly 1 in place, the lower portion 95 possesses threads on an interior surface thereof 98 which can be matingly engaged with the threads 97 of securing portion 96 so as to secure the lower portion 95 to the securing portion 96, and each of the lower portion 95 and securing portion 96 have an outermost width that is greater than that of the drill stop member 5. In this manner, once the lower portion 95 and securing portion 96 are secured together, the lower portion 95 and securing portion 96 hold the lower end 100 of the drill stop member 5 firmly in place within the assembly.
To secure the upper end of the assembly 1 in place the threads 90 of the drill stop member 5 are matingly engaged with the threads 103 of the upper portion 91. The upper end 6 of the seismic drilling bit 2 is then inserted through the opening in the cap portion 93, and the cap portion is then moved downwardly, whereby the threads 92 of the upper portion 91 can be matingly engaged with the threads 105 on an interior surface of the cap portion 93 to secure the upper half the assembly. The drilling process is then begun, in a one-step process, whereby the drill hole is first created, then, as downward pressure is continued, the flange portion 15 of the stabilizer 7 is pushed to extend into the drill hole and abut an inside portion thereof. In this manner, the flange portion 15 stabilizes the seismic tool assembly 1 during the drilling process. Once the seismic drilling bit 2 is sunk to a pre-set depth and rotated, rotational drilling (and tilted rotational drilling as previously described) by the seismic drilling bit 2 can then be effected in creating an enlarged area of the lowermost end of a drill hole.
Of course, by virtue of the cutting portions 10 having an outermost width (and operational cutting radius) that is slightly greater than that of the bit body 4, these cutting portions 10, when the seismic drilling bit 2 is rotated, enlarge a circumference of the drill hole at the lowermost end (in creating the enlarged area) that is greater than that of the remainder of the drill hole. In this manner, once the enlarged area has been created, and the seismic drilling bit 2 removed from the drill hole, the anchor (not shown) can be inserted, and, when the anchors have been flanged outwardly by conventional means within the drill hole, the flange portions of the anchor can rest within the enlarged area, thus securely retaining the anchor in place.
In a still further alternative embodiment of the fully connected seismic tool assembly, shown in Figures 8 to 13, there is shown a seismic tool assembly for use in the later insertion and setting of anchors shown generally at 1 in accordance with a first exemplary embodiment of the present invention. As previously described with other embodiments, the seismic tool assembly 1, as shown in Figure 9, is to be rotatably mounted onto a drill by way of a drill spindle (not shown).
In a preferred embodiment, this embodiment of the seismic tool assembly 1 is for use in the later insertion and setting of anchors into concrete, stone, masonry and cementuous materials (though it will be understood that other variations to this are possible) and comprises a seismic drilling bit 2, a stabilizer 7, a drill stop member 5 and a cap portion 93, as hereinafter described.
Preferably, the components of the assembly, including the seismic drilling bit 2 (see Figure 9), stabilizer 7 (see Figure 11), and drill stop member 5 (see Figure 8), will be made of a durable, machinable metal. The seismic drilling bit 2 is, preferably, substantially cylindrical in shape and is of a one-piece construction that comprises an upper end 6 and a lower end 8 which are integrally connected to one another.
With reference to Figure 8, it can be seen that the bit body 4 of the seismic drilling bit 2 can effect the drilling of a drill hole, and has a first diameter (and cutting radius) sized to readily fit into a drill hole (not shown), and possesses, as most conventional drill bits do, at least one cutting edge and at least one groove extending in a helical fashion along a length of the bit body 4 of the seismic drilling bit 2. In a preferred embodiment, these extend along a substantial length of the bit body 4, or, alternatively, extend along at least half a length of the bit body 4. Preferably, the first diameter of the upper end 6 of the bit body 4 is less than or equal to a diameter of the drill hole into which the seismic drilling bit 2 of the present invention is to be inserted.
The upper end 6 of the seismic drilling bit 2, with reference to Figure 9, is constructed and arranged to be releasably secured to a drill by way of a drill spindle (not shown). In an exemplary embodiment, the distal lower end 8 of the seismic drilling bit 2 has a drill tip 11 extending generally outwardly from the lower end 8.
The lower end 8 of the seismic drilling bit 2 has a cutting portion 10 positioned on each side of the lower end 8 of the seismic drilling bit 2, the cutting portions 10 having a greater outermost width than that of the bit body 4 whereby, when the seismic drilling bit 2 is inserted fully into a lowermost end of the drill hole and rotated, the cutting portions 10 enlarge a circumference of the drill hole at the lowermost end thereof that is greater than the circumference of the remainder of the shaft of the drill hole. Preferably, the cutting portions 10 extend outwardly from substantially around an entirety of the lower end 8 of the seismic drilling bit 2, as seen in Figure 9. In an alternative embodiment (which is not shown), the lower end 8 of the seismic drilling bit 2 can have a cutting portion positioned on only one side of the lower end 8 of the seismic drilling bit 2.
In a still further embodiment (not shown), the bit body 4 of the seismic drilling bit 2 has a diameter (and cutting radius) that is less than that of the drill hole, with the cutting portions 10, of course, still having a greater outermost width (and cutting radius) than that of the bit body 4. In this manner, with the bit body 4 of the seismic drilling bit 2 having a width that is less than that of the drill hole, the initial insertion of the seismic drilling bit 2 into the drill hole is made easier, whereby the bit does not need to be as readily forcibly inserted.
With reference to Figure 10, the drill stop member 5, preferably, has an opening 112 defined therethrough, and is used for receiving an insertion of the seismic drilling bit 2.
Preferably, the opening 112 in the drill stop member 5 is positioned at a substantially central location of the drill stop member 5. The drill stop member 5 aids in the accurate and gradual insertion of the seismic drilling bit 2 into the drill hole. The drill stop member 5 further comprises, with reference to Figure 11, a dust exit opening 3 defined therein for allowing dust to be removed from the assembly during the drilling process, the dust exit opening 3 being positioned at substantially a middle portion of the drill stop member 5. It will, of course, also be understood that the stabilizer 7 could also possess such a dust exit opening.
The seismic tool assembly 1 further comprises, with reference to Figures 8 to 13, a stabilizer 7 for receiving, and having mounted thereon, the drill stop member S. The stabilizer 7 comprises a flange portion 15 constructed and arranged to extend into the drill hole and abut an inside portion thereof. In an alternative embodiment (not shown), the flange portion 15 of the stabilizer 7 could be tapered at a distal end thereof so as to further aid in the accurate and gradual insertion of the seismic drilling bit 2 into the drill hole. It will of course be understood that the dimensions of the stabilizer 7, or indeed of any of the components of the assembly 1 could be varied, depending upon the size of the drill bit to be used. In an exemplary embodiment, the stabilizer 7, with reference to Figure 11, has a central opening 114 which corresponds with each of the openings of the drill stop member 5 and the drill hole.
With further reference to Figure 11, it can be seen that the opening 114 on the stabilizer 7 has a diameter larger than the cutting portions 10 of the bit body 4. By virtue of the opening 114 being greater than the cutting portions 10 of the bit body 4 to accommodates passage therethrough, this allows the insertion of the seismic drilling bit 2 into the drill hole (not shown), and permits limited tilting movement of the bit body 4 from its vertical axis within the opening 114 (and allows for less physical contact with, particularly, the flange portion 15) on the stabilizer 7 during the drilling process to further enlarge a lowermost end of the drill hole, it being understood that this tilting rotational drilling of the lower end of the drill hole by the drill bit 2 within the opening 114 can be done through 360 degrees, whereby the lower end of the drill hole can be made to be conical and funnel-shaped, for receiving anchors therein.
The stabilizer 7 further comprises, as shown in Figure 10 and 11, the stabilizer 7 is comprised of a lower portion 95 and a securing portion 96, which possesses threads 97 towards a lowermost end thereof. In an exemplary embodiment, each of the lower portion 95 and a securing portion 96 comprise openings therethrough which corresponds with each of the openings of the drill stop member 5 and the drill hole. In positioning the drill stop member 5 within the assembly, an upper end 99 of the drill stop member 5 is passed through an opening in the securing portion 96, and a lower end 100 of the drill stop member 5 is then positioned within the lower portion 95, the lower end 100 resting on abutment region 101. The lower end 100 of drill stop member 5, when in place, abuts abutment region 101 so as to inhibit the downward movement of drill stop member 5 within the lower portion 95. To secure the drill stop member 5 in place, the lower portion 95 possesses threads on an interior surface thereof 98 which can be matingly engaged with the threads 97 of securing portion 96 so as to secure the lower portion 95 to the securing portion 96, and each of the lower portion 95 and securing portion 96 have an outermost width that is greater than that of the drill stop member S. In this manner, once the lower portion 95 and securing portion 96 are secured together, the lower portion 95 and securing portion 96 hold the lower end 100 of the drill stop member 5 firmly in place within the assembly.
Figures 9, 10 and 12 illustrate the seismic drill bit 2 having abutment member 109 thereon, the abutment member 109 having a greater width than a remainder of the seismic drill bit 2. When the seismic drill bit 2 is inserted through the uppermost end 99 of the drill stop member 5, and as the seismic drill bit 2 continues to be inserted therethrough, abutment member 109 on the seismic drilling bit 2 eventually comes into contact with the uppermost end 99 of the drill stop member 5, thus restricting downward movement of the seismic drilling bit 2 to a pre-set depth.
To secure the upper end of the assembly 1 in place, as shown in Figures 12 and 13, the drill stop member 5 itself possesses threads 90 towards an uppermost end 99 thereof, which can be matingly engaged with cap portion 93, which also possesses threads 105 on an interior surface thereof. The cap portion 93, as shown in Figure 9, will, in an exemplary embodiment, have an opening 124 (see Figure 9) defined therethrough for receiving an insertion of the seismic drill bit 2 therethrough, which corresponds with the central openings of the stabilizer 7 and the drill stop member S. The cap portion 93 is positioned over the distal end 6 of the seismic drilling bit 2, and the cap portion 93 is then moved downwardly to cover and surround a substantial middle portion of the seismic drilling bit 2, whereby the threads 105 on an interior surface of the cap portion 93 (see Figure 9) can then be matingly engaged with the threads 90 of the drill stop member 5 to secure the upper half the assembly. When disengagement of the drill stop member 5 and cap portion 93 is desired, the threaded portions of each can be untightened so as to permit the disengagement of components.
In operation the seismic drill bit 2 is inserted through the uppermost end 99 of the drill stop member 5, whereby, as seismic drill bit 2 continues to be inserted therethrough, abutment member 109 on the seismic drilling bit 2 comes into contact with the uppermost end 99 of the drill stop member 5, thus restricting downward movement of the seismic drilling bit 2 to a pre-set depth, see Figures 10 and 12, which illustrates that the uppermost end 99 of the drill stop member 5 and the abutment member 109 on the seismic drilling bit 2 have a width that is substantially equal.
A lower end 100 of the drill stop member 5 is then positioned within the lower portion 95, the lower end 100 resting on abutment region 101. The lower end 100 of drill stop member 5, when in place, abuts abutment region 101 so as to inhibit the downward movement of drill stop member 5 within the lower portion 95. Once this is done the seismic drilling bit 2 is then inserted downwardly through the openings in each of the securing portion 96, the drill stop member 5 and the lower portion 95. Of course, the lower end 8 of the seismic drilling bit 2 emerges through opening 114 in the lower portion 95.
To secure the drill stop member 5 in place, and the lower end of the assembly 1 in place, the lower portion 95 possesses threads on an interior surface thereof 98 which can be matingly engaged with the threads 97 of securing portion 96 so as to secure the lower portion 95 to the securing portion 96, and each of the lower portion 95 and securing portion 96 have an outermost width that is greater than that of the drill stop member 5. In this manner, once the lower portion 95 and securing portion 96 are secured together, the lower portion 95 and securing portion 96 hold the lower end 100 of the drill stop member 5 firmly in place within the assembly, as shown in Figure 12.
To secure the upper end of the assembly 1 in place, a cap portion 93 having an opening defined therethrough is positioned over the distal end 6 of the seismic drilling bit 2, and the cap portion 93 is then moved downwardly to cover and surround a substantial middle portion of the seismic drilling bit, whereby the threads 105 on an interior surface of the cap portion 93 (see Figure 9) can be matingly engaged with the threads 90 of the drill stop member 5 to secure the upper half the assembly, as shown in Figure 12. The drilling process is then begun, in a one-step process, whereby the drill hole is first created, then, as downward pressure is continued, the flange portion 15 of the stabilizer 7 is pushed to extend into the drill hole and abut an inside portion thereof. In this manner, the flange portion 15 stabilizes the seismic tool assembly 1 during the drilling process. Once the seismic drilling bit 2 is sunk to a pre-set depth and rotated, rotational drilling (and tilted rotational drilling as previously described) by the seismic drilling bit 2 can then be effected in creating an enlarged area of the lowermost end of a drill hole.
Of course, by virtue of the cutting portions 10 having an outermost width (and operational cutting radius) that is slightly greater than that of the bit body 4, these cutting portions 10, when the seismic drilling bit 2 is rotated, enlarge a circumference of the drill hole at the lowermost end (in creating the enlarged area) that is greater than that of the remainder of the drill hole. In this manner, once the enlarged area has been created, and the seismic drilling bit 2 removed from the drill hole, the anchor (not shown) can be inserted, and, when the anchors have been flanged outwardly by conventional means within the drill hole, the flange portions of the anchor can rest within the enlarged area, thus securely retaining the anchor in place.
