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 surrounding the 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. A cap portion and an upper end of the stabilizer are threaded for permitting threaded engagement of the cap portion to the threaded upper portion of the stabilizer so as to prevent disengagement of the drill stop member from the stabilizer during a drilling process.
Description
3 The present invention relates to a seismic tool assembly 4 meant to be used for the later insertion and setting of anchors, such as drop-in and wedge type anchors into brittle materials 6 such as concrete, stone, masonry and cementuous materials. More 7 particularly, the present invention relates to a seismic tool 8 assembly for effecting a drill hole and enlarging a lowermost 9 end thereof to have a greater circumference than that of the remainder of the drill hole whereby an anchor can be set more 11 securely therein.
Anchors are conventionally used in construction to attach 16 various components of a building construction to an overhead 17 ceiling or other structure. Such components to be attached can 18 relate to, for example, services that provide plumbing, 19 electrical, drainage, sprinkler system piping and drop ceilings.
From these anchors, which are usually of the wedge or drop-in 21 type variety, all of the above services and ceilings are 22 suspended or secured.
23 Conventionally, in setting anchors in concrete to suspend 24 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 26 inserted into the pre-drilled hole. However, when setting such 27 anchors in concrete it is not uncommon for such anchors to 28 weaken and loosen over time, particularly in situations where 29 cracking or chipping of the concrete around the pre-drilled hole has occurred.
1 Furthermore, studies have revealed that cracking can 2 typically occur in the concrete element, and that such cracks 3 can significantly impact the performance of anchors. Cracks can 4 originate on a concrete beam or slab in a variety of ways, such as creep, temperature settlement of the support or foundation, 6 thermal expansion and contraction stress overload, or from a 7 natural disaster such as an earthquake or flood. In such 8 situations, the situation can arise where, if one such concrete 9 anchor fails and lets go, the remaining anchors, by virtue of the weight they additionally assume in light of such failure, 11 can also similarly collapse and fail.
12 It has been found that enlarging the lowermost (interior) 13 portion of a drill hole can allow an anchor to be set more 14 securely therein. It has further been found that providing a drill hole with an enlarged lower end having a greater 16 circumference than that of the remainder of the drill hole can 17 be advantageously provided by a drill bit having an enlarged 18 cutting portion adjacent the tip, which is inserted into the 19 drill hole, whereby the enlargement of the cutting portion is configured so that it can pass through the shaft of the pre-21 drilled hole to be enlarged.
23 It would therefore be advantageous to have an improved 24 seismic tool assembly meant to be used for the later insertion and setting of anchors into brittle materials such as concrete, 26 stone, masonry and cementuous materials.
28 it would be further advantageous to have an improved 29 seismic tool assembly for use in a one step process for both creating a drill hole and, at the same time, enlarging a 31 lowermost end of a drill hole, wherein the lowermost end of the l drill hole can be further drilled and enlarged to have a greater 2 circumference than that of the remainder of the drill hole, 3 wherein an anchor can later be positioned and securely retained 4 within the enlarged area.
6 It would also be further advantageous to have an improved 7 seismic tool assembly meant to be used for the later insertion 8 and setting of anchors which utilizes a stabilizer having an 9 opening corresponding with the drill hole for receiving an insertion of the bit body into the drill hole, so as to aid in 11 accurately inserting the drill bit into the drill hole. It would 12 also be still further advantageous to have a stabilizer which 13 possesses a tapered interior, with an upper end of the 14 stabilizer having a narrower opening for receiving the insertion of the bit body therein and thus stabilize the bit body, and the 16 lower end of the stabilizer having a larger sized opening 17 greater than that of the upper end, so as to increase the range 18 of motion of the drilling bit and permit limited tilting 19 movement of the bit within the stabilizer during the drilling process so as to further aid in enlarging a lowermost end of the 21 drill hole to receive an anchor. To this end, the present 22 invention effectively addresses this need.
26 The present invention provides an improved seismic tool 27 assembly meant to be used for the later insertion and setting of 28 anchors for the insertion and setting of anchors into brittle 29 materials such as concrete, stone, masonry and cementuous materials.
32 The present invention also provides an improved seismic 33 tool assembly meant to be used for the later insertion and 1 setting of anchors, which can be used in a one step process for 2 both creating a drill hole and, at the same time, for enlarging 3 a lowermost end of a drill hole to have a greater circumference 4 than that of the remainder of the drill hole, whereby an anchor can be later set and positioned more securely therein.
7 The present invention also provides an improved seismic 8 tool assembly meant to be used for the later insertion and 9 setting of anchors which utilizes a stabilizer having an opening corresponding with the drill hole for receiving an insertion of 11 the bit body into the drill hole, so as to aid in accurately 12 inserting the drill bit into the drill hole.
14 The present invention also provides an improved seismic tool assembly meant to be used for the later insertion and 16 setting of anchors which utilizes a drill stop member which 17 possesses a tapered interior, with an upper end of the drill 18 stop member having a narrower opening for receiving the 19 insertion of the bit body therein and thus stabilize the bit body, and the lower end of the drill stop member having a larger 21 sized opening greater than that of the upper end, so as to 22 increase the range of motion of the drilling bit and permit 23 limited tilting movement of the bit within the drill stop member 24 during the drilling process so as to further aid in enlarging a lowermost end of the drill hole.

The invention will be described for the purposes of 16 illustration only in connection with certain embodiments;
17 however, it is to be understood that other objects and 18 advantages of the present invention will be made apparent by the 19 following description of the drawings according to the present invention. While a preferred embodiment is disclosed, this is 21 not intended to be limiting. Rather, the general principles set 22 forth herein are considered to be merely illustrative of the 23 scope of the present invention and it is to be further 24 understood that numerous changes may be made without straying from the scope of the present invention.
26 The present invention consists of an improved seismic tool 27 assembly designed for effecting a drill hole and enlarging a 28 lowermost end thereof to have a greater circumference than that 1 of the remainder of the drill hole whereby an anchor can be set 2 more securely therein.
3 Referring to Figure 9, there is shown a seismic tool 4 assembly for use in the later insertion and setting of anchors shown generally at 1 in accordance with a first exemplary 6 embodiment of the present invention. In a preferred embodiment, 7 as hereinafter described, the seismic tool assembly 1 is to be 8 rotatably mounted onto a drill by way of a drill spindle (not 9 shown). It will be understood that there are numerous variations as to the types of attachments to a drill or otherwise that the 11 seismic tool assembly 1 of the present invention could be 12 mounted thereon, as would be readily apparent to one skilled in 13 the art.
14 In a preferred embodiment, the seismic tool assembly 1 is for use in the later insertion and setting of anchors into 16 concrete, stone, masonry and cementuous materials (though it 17 will be understood that other variations to this are possible) 18 and comprises a seismic drilling bit 2, a stabilizer 7, and a 19 drill stop member 5, as hereinafter described.
Preferably, the seismic drilling bit 2 will be made of a 21 durable, machinable metal and is substantially cylindrical in 22 shape. The seismic drilling bit 2 is, preferably, of a one-piece 23 construction that comprises an upper end 9 and a lower end 8 24 which are integrally connected to one another.
With reference to Figure 1, it can be seen that the bit 26 body 4 of the seismic drilling bit 2 can effect the drilling of 27 a drill hole, and has a first diameter (and cutting radius) 28 sized to readily fit into a drill hole (not shown), and 29 possesses, as most conventional drill bits do, at least one 1 cutting edge and at least one groove extending in a helical 2 fashion along a length of the bit body 4 of the seismic drilling 3 bit 2. In a preferred embodiment, these extend along a 4 substantial length of the bit body 4, or, alternatively, extend along at least half a length of the bit body 4. Preferably, the 6 first diameter of the upper end 9 of the bit body 4 is less than 7 or equal to a diameter of the drill hole into which the seismic 8 drilling bit 2 of the present invention is to be inserted.
9 The proximal upper end 9 of the seismic drilling bit 2 is constructed and arranged to be releasably secured to a drill by 11 way of a drill spindle (not shown). In an alternative 12 embodiment, the distal lower end 8 of the seismic drilling bit 2 13 can have a tapered end (not shown) and a drill tip 11 extending 14 generally outwardly from the tapered end.
The lower end 8 of the seismic drilling bit 2 has a cutting 16 portion 10 positioned on each side of the lower end 8 of the 17 seismic drilling bit 2, the cutting portions 10 having a greater 18 outermost width than that of the bit body 4 whereby, when the 19 seismic drilling bit 2 is inserted fully into an lowermost end of the drill hole and rotated, the cutting portions 10 enlarge a 21 circumference of the drill hole at the lowermost end thereof 22 that is greater than the circumference of the remainder of the 23 shaft of the drill hole. Preferably, the cutting portions 10 24 extend outwardly from substantially around an entirety of the lower end 8 of the seismic drilling bit 2, as seen in Figure 1.
26 In an alternative embodiment (which is not shown), the lower end 27 8 of the seismic drilling bit 2 can have a cutting portion 28 positioned on only one side of the lower end 8 of the seismic 29 drilling bit 2.
1 In a still further embodiment (not shown), the bit body 4 2 of the seismic drilling bit 2 has a diameter (and cutting 3 radius) that is less than that of the drill hole, with the 4 cutting portions 10, of course, still having a greater outermost width (and cutting radius) than that of the bit body 4. In this 6 manner, with the bit body 4 of the seismic drilling bit 2 having 7 a width that is less than that of the drill hole, the initial 8 insertion of the seismic drilling bit 2 into the drill hole is 9 made easier, whereby the bit does not need to be as readily forcibly inserted.
11 With reference to Figure 2, the drill stop member 5, 12 preferably, has an opening 6 defined therethrough, and is used 13 for receiving an insertion of the seismic drilling bit 2. Figure 14 2 illustrates the upper end 30 of the drill stop member 5 having a shape which corresponds substantially to a shape of the 16 cutting portion 10 of the bit body 2 for receiving the insertion 17 of the bit body therethrough. With reference to Figure 3, it can 18 be seen that the lower end 32 of the drill stop member 5 has an 19 opening greater than that of the upper end 30, so as to permit limited tilting movement of the bit body from its vertical axis 21 within the drill stop member 5 during the drilling process to 22 further enlarge a lowermost end of the drill hole, it being 23 understood that this tilting rotational drilling of the lower 24 end of the drill hole by the drill bit 2 within the drill stop member 5 can be done through 360 degrees. This rotational 26 movement can be seen with reference to Figure 11, whereby the 27 lower end of the drill hole 45 can be seen to be funnel-shaped, 28 for receiving anchors therein.
29 Preferably, the opening in the drill stop member 5 is positioned at a substantially central location of the drill stop 1 member 5. The drill stop member 5 aids in the accurate and 2 gradual insertion of the seismic drilling bit 2 into the drill 3 hole. The drill stop member 5 further comprises a dust exit 4 opening 3 defined therein for allowing dust to be removed from the assembly during the drilling process, the dust exit opening 6 3 being positioned at substantially a middle portion of the 7 drill stop member 5. It will, of course, also be understood that 8 the stabilizer 7 could also possess such a dust exit opening.
9 The seismic tool assembly 1 further comprises, with reference to Figures 4 to 7, a stabilizer 7 for receiving, and 11 having mounted thereon, the drill stop member 5. The stabilizer 12 7 comprises a flange portion 15 constructed and arranged to 13 extend into the drill hole and abut an inside portion thereof.
14 In an alternative embodiment (not shown), the flange portion 15 of the stabilizer 7 could be tapered at a distal end thereof so 16 as to further aid in the accurate and gradual insertion of the 17 seismic drilling bit 2 into the drill hole. In a preferred 18 embodiment, and with reference to Figure 6, side portions of the 19 flange portion 15 have an elongated opening 44 defined along a length thereof, for allowing passage of the cutting portion of 21 the bit body when the bit body is inserted through the 22 stabilizer 7.
23 The stabilizer 7 further comprises an upper portion 34 24 integrally connected to the flange portion 15, the upper portion 34 having, with reference to Figure 7, a recessed upper surface 26 36 for receiving the drill stop member 5 mounted thereon. With 27 further reference to Figure 4, it can be seen that the central 28 opening 38 on the stabilizer 7 has a shape which corresponds 29 substantially to a shape of the cutting portion 10 of the bit 1 body for receiving, and allowing therethrough, the insertion of 2 the seismic drilling bit 2.
3 Preferably, the stabilizer 7 has the central opening 38 4 which corresponds with each of the openings of the drill stop member 5 and the drill hole, it being understood that the drill 6 stop member 5 restricts downward drilling movement of the 7 seismic drilling bit 2 into the drill hole to a pre-set depth, 8 through virtue of the bit body 4 of the seismic drilling bit 2 9 only being able to be pushed downwardly within the drill stop member 5 (mounted on the stabilizer 7) to a certain point, at 11 which it comes into contact with the drill stop member 5, thus 12 restricting its downward movement.
13 The seismic assembly of the present invention further 14 comprises locking means 40, which are positioned substantially around the flange portion 15 of the stabilizer 7 for selectively 16 stabilizing the seismic drilling bit 2 and for preventing 17 disassembly of the seismic drilling bit 2 from the drill stop 18 member 5 and the stabilizer 7. In a preferred embodiment, the 19 locking means 40 is a substantially circular ring which at least partially encircles an outside of the flange portion 15, the 21 locking means 40 being slidably movable to restrict 22 disengagement of the seismic drilling bit 2 from the stabilizer 23 7 and the drill stop member 5 mounted thereon. Figure 4 24 illustrates the locking means 40 in a substantially open position to receive an insertion of the bit body 2 therethrough, 26 and Figure 5 illustrates the locking means 40 in a substantially 27 closed position, having been slightly rotated so as to cover the 28 elongated opening 44 in the side portions of the flange portion 29 15, and thus restrict the disengagement of the bit body 2 from the interconnected drill stop member 5 and stabilizer 7. The 1 interconnection of the stabilizer 7 to the drill stop member 5 2 can be plainly seen in Figure 8.
3 In operation, and as seen in Figure 10, the drill stop 4 member 5 is mounted upon the stabilizer 7, and the seismic drilling bit 2 is inserted through the openings in the drill 6 stop member 5 and the stabilizer 7. Of course, seismic drilling 7 bit 2 is to be rotatably mounted onto a drill (not shown), and 8 the assembly is positioned over a surface where a drill hole is 9 to be made. Once the seismic drilling bit 2 is sunk to a pre-set depth and rotated, rotational drilling (and tilted rotational 11 drilling as previously described) by the seismic drilling bit 2 12 can then be effected in creating an enlarged area of the 13 lowermost end of a drill hole.
14 Of course, by virtue of the cutting portions 10 having an outermost width (and operational cutting radius) that is 16 slightly greater than that of the bit body 4, these cutting 17 portions 10, when the seismic drilling bit 2 is rotated, enlarge 18 a circumference of the drill hole at the lowermost end (in 19 creating the enlarged area) that is greater than that of the remainder of the drill hole. In this manner, once the enlarged 21 area has been created, and the seismic drilling bit 2 removed 22 from the drill hole, the anchor (not shown) can be inserted, 23 and, when the anchors have been flanged outwardly by 24 conventional means within the drill hole, the flange portions of the anchor can rest within the enlarged area, thus securely 26 retaining the anchor in place.
27 In a still further embodiment (not shown) the bit body 4 of 28 the seismic drilling bit 2 can be tapered, to have a narrower 29 circumference than that of the lowermost end of the bit body. In this manner, the tapered drill bit allows for less physical 1 contact with the drill stop member 5 and increases the range of 2 motion of the seismic drilling bit 2 in permitting limited 3 tilting movement of the bit to enlarge a lowermost end of the 4 drill hole 45. It will also be understood that the seismic drilling bit 2 can come in several set depths, or the drill stop 6 member 5 itself could be adjustable through a locking screw.
7 In a still further embodiment (not shown), the drill stop 8 member 5 is integrally mounted upon the stabilizer 7, and the 9 seismic drilling bit 2 is inserted through the openings in the drill stop member 5 and the stabilizer 7. In this manner, the 11 drill stop member 5 is permanently connected and un-detachably 12 mounted upon the stabilizer 7, and the seismic drilling bit 2 is 13 permanently inserted through the openings of the drill stop 14 member 5 and the stabilizer 7 so as to be of a permanently connected one-piece construction.
16 In a still further embodiment of the fully connected 17 seismic tool assembly, shown in Figure 12B, the drill stop 18 member 5 is mounted upon the stabilizer 7, and the bit body 2 is 19 inserted through the openings in the drill stop member 5 and the stabilizer 7 whereby the drilling of a drill hole can be 21 effected. Of course, it will be understood that the stabilizer 22 7, when positioned within the drill hole, helps to maintain the 23 integrity of the drill hole by virtue of flange portion 15 (as 24 shown in Figure 9), which is constructed and arranged to extend into the drill hole 45 and abut an inside portion thereof.
26 As shown in Figure 12B, the stabilizer 7 further comprises 27 an upper portion 34. This upper portion 34, as can be seen in 28 Figure 8, has an outermost width that is greater than that of 29 the flange portion 15. This upper portion 34 receives the drill stop member 5 mounted thereon, as similarly shown in Figure 8.
1 In this embodiment, the drill stop member 5 possesses a 2 lower portion 56, a recessed middle portion 58 and an upper 3 portion 60, all of which are, in an exemplary embodiment, 4 integrally connected together, though of course variations to this are possible, as these could potentially be interconnected.
6 As can be seen in Figure 12B, the lower portion 56 and the upper 7 portion 60 have an outermost width that is substantially equal, 8 while each of the lower portion 56 and the upper portion 60 have 9 an outermost width that is greater than that of the recessed middle portion 58.
11 In a further embodiment, the upper portion 34 of the 12 stabilizer 7 will have holding screws 54 connected thereto, 13 which are positioned at opposed sides of the upper portion 34 14 approximately at a same height as the recessed middle portion 58 of the drill stop member 5. These holding screws 54 can either 16 be turned and adjustably moved towards the recessed middle 17 portion 58 of the drill stop member 5 (so as to maintain the 18 connection of the drill stop member 5 to the stabilizer 7 during 19 a drilling process), or adjustably movable away from the recessed middle portion of the drill stop member so as to permit 21 disengagement of the drill stop member from the stabilizer.
22 Of course, as with the aforementioned embodiment of the 23 seismic tool assembly shown in Figure 1, the lower end 8 of the 24 bit body 4 has a cutting portion 10 positioned on each side of the lower end 8 of the bit body 4, the cutting portions 10 26 having a greater outermost width than that of the bit body 4.
27 When the seismic drilling bit is inserted, it creates the drill 28 hole 45 in a one-step process, and it will also be understood 29 that, in a still further embodiment, rotational drilling (and tilted rotational drilling as previously described) by the 1 seismic drilling bit 2 can also be effected in creating an 2 enlarged area of the lowermost end of a drill hole 45, creating 3 a funnel, conical shape in the drill hole 45. In a further 4 embodiment, the bit body 4 can possess a narrower circumference towards a lowermost end of the bit than that of the uppermost 6 end of the bit body. In this manner, the drill bit allows for 7 less physical contact with, particularly, the flange portion 15 8 of the stabilizer 7 and increases the range of motion of the 9 seismic drilling bit 2, when tilted, to provide a greater range of tilting movement of the bit in enlarging a lowermost end of 11 the drill hole 45.
12 A still further embodiment of the fully connected seismic 13 tool assembly is shown in Figure 12A. In a similar manner to the 14 embodiment shown in Figure 15, the drill stop member 5 is mounted within the stabilizer 7, and the bit body 4 is inserted 16 through openings in the drill stop member 5 and the stabilizer 7 17 whereby the drilling of a drill hole can be effected. In doing 18 so, the drill stop member 5, when in place, abuts an interior 19 portion 70 within the stabilizer 7 so as to inhibit the downward movement of drill stop member 5 within the stabilizer 7, thus 21 restricting the drill bit 4 (surrounded by the drill stop member 22 5) to achieving a pre-set cutting depth within the drill hole 23 45. Of course, it will be understood that the stabilizer 7, when 24 positioned, will substantially surround the drill hole 45, and, as shown in Figure 12A, a lower portion of the stabilizer 7 26 encircles and surrounds the drill hole 45, the lower portion 27 having a greater outermost width than that of the remainder of 28 the stabilizer 7. It will of course be understood that the 29 dimensions of the stabilizer 7 could be varied, depending upon the size of the drill bit to be used. Unlike the embodiment 31 shown in Figure 12B, however, tilted rotational drilling of the 1 drill stop member 5 within the stabilizer 7, as shown in Figure 2 12A, is not to be effected. Rather, the drill stop member 5 3 within the stabilizer 7 is rigid and does not have a range of 4 tilted rotation. Instead, when the seismic drilling bit is inserted, it creates the drill hole 45 in a one-step process, 6 and the circumference of the drill hole 45 at the lowermost end 7 thereof is the same circumference of the remainder of the drill 8 hole. Of course, it will also be understood that, in a still 9 further embodiment, rotational drilling (and tilted rotational drilling as previously described) by the seismic drilling bit 11 can also be effected in creating an enlarged area of the 12 lowermost end of a drill hole, in that the drill stop member 5 13 within the stabilizer 7 is not rigidly retained, so that when 14 the seismic drilling bit is inserted fully into a lowermost end of the drill hole 45 and rotated, the cutting portions 10 16 enlarge a circumference of the drill hole 45 at the lowermost 17 end thereof that is greater than the circumference of the 18 remainder of the shaft of the drill hole 45.
19 In a still further embodiment of the fully connected seismic tool assembly, shown in Figures 13A and 14, the drill 21 stop member 5 is mounted within the stabilizer 7, and the bit 22 body 4 is inserted through openings in the drill stop member 5 23 and the stabilizer 7 whereby the drilling of a drill hole can be 24 effected. In doing so, the drill stop member 5, when in place, abuts an interior portion 70 within the stabilizer 7 so as to 26 inhibit the downward movement of drill stop member 5 within the 27 stabilizer 7, thus restricting the drill bit (surrounded by the 28 drill stop member 5) to achieving a pre-set cutting depth within 29 the drill hole 45. Of course, it will be understood that the stabilizer 7, when positioned, will substantially surround the 31 drill hole 45, and, as shown in Figure 13A, a lower portion 66 1 of the stabilizer 7 encircles and surrounds the drill hole 45, 2 the lower portion having a greater outermost width than that of 3 the remainder of the stabilizer 7. It will of course be 4 understood that the dimensions of the stabilizer could be varied, depending upon the size of the drill bit to be used.
6 Of course, as with the aforementioned embodiment of the 7 seismic tool assembly shown in Figure 12A, tilted rotational 8 drilling of the drill stop member 5 within the stabilizer 7 is 9 not to be effected. Rather, the drill stop member 5 within the stabilizer 7 is rigid and does not have a range of tilted 11 rotation. Instead, when the seismic drilling bit is inserted, it 12 creates the drill hole 45 in a one-step process, and the 13 circumference of the drill hole 45 at the lowermost end thereof 14 is the same circumference of the remainder of the drill hole 45.
In an alternative embodiment of the fully connected seismic 16 tool assembly, shown in Figure 13B, the drill stop member 5 is 17 mounted upon the stabilizer 7, and the bit body 2 is inserted 18 through the openings in the drill stop member 5 and the 19 stabilizer 7 whereby the drilling of a drill hole can be effected. In this embodiment, the stabilizer 7 possesses flange 21 portion 15 (similar to the embodiment shown in Figure 9), which 22 is constructed and arranged to extend into the drill hole 45 and 23 abut an inside portion thereof. In this embodiment, the lower 24 portion 66 of the stabilizer 7 possesses threads on an interior surface thereof which can be matingly engaged with similar 26 threads contained towards an uppermost end of flange portion 15.
27 When disengagement of the lower portion 66 of the stabilizer 7 28 and flange portion 15 is desired, the threaded portions of each 29 can be untightened so as to permit disengagement of the flange portion 15 from the stabilizer 7. In this manner, a user can l utilize the tilted rotational drilling of the drill stop member 2 5 within the stabilizer 7, as shown in Figure 13B, or, simply 3 remove the flange portion 15 with a view to utilizing non-4 rotational drilling of the drill stop member 5 within the stabilizer 7, as shown in Figure 13A, whereby the drill stop 6 member 5 within the stabilizer 7 is rigid and does not have a 7 range of tilted rotation. It will be understood that flange 8 portion 15 will serve to limit somewhat the extent to which 9 rotational drilling can be effected, and thus protect the walls of the drill hole 45, as the bit 2 will contact the flange 11 portion 15 if the range of rotation is too great.
12 Of course, as with the aforementioned embodiment of the 13 seismic tool assembly shown in Figure 12B, when the seismic 14 drilling bit is inserted, it creates the drill hole 45 in a one-step process, and it will also be understood that, in a still 16 further embodiment, rotational drilling (and tilted rotational 17 drilling as previously described) by the seismic drilling bit 18 body 4 can also be effected in creating an enlarged area of the 19 lowermost end of a drill hole 45, creating a funnel, conical shape in the drill hole 45. In a further embodiment, the bit 21 body 4 can possess a narrower circumference towards a lowermost 22 end of the bit than that of the uppermost end of the bit body.
23 In this manner, the drill bit allows for less physical contact 24 with, particularly, the flange portion 15 of the stabilizer 7 and increases the range of motion of the seismic drilling bit, 26 when tilted, to provide a greater range of tilting movement of 27 the bit in enlarging a lowermost end of the drill hole 45.
28 As shown in Figures 13A, 13B and 14, the stabilizer 7 29 further comprises an upper portion 68. This upper portion 68, as can be seen in Figure 14, has an outermost width that is greater 1 than that of the interior portion 70, and posesses threads 72 2 towards an uppermost end thereof. With reference to Figure 14, 3 cap portion 74, which also possesses threads on an interior 4 surface thereof (not shown) can be matingly engaged with the threads of upper portion 68 so as to secure the upper portion 68 6 to the cap portion 74, thus securing the drilling assembly 7 together, in an exemplary embodiment, though of course 8 variations to this are possible. The cap portion will, in an 9 exemplary embodiment, have an opening defined therethrough (not shown) for receiving an insertion of the bit body therethrough, 11 which corresponds with the central opening of the stabilizer 7.
12 When disengagement of the upper portion 68 and cap portion 74 is 13 desired, the threaded portions of each can be untightened so as 14 to permit disengagement of the drill stop member 5 from the stabilizer 7.
16 In a still further embodiment of the fully connected 17 seismic tool assembly, shown in Figure 15, the drill stop member 18 5 is mounted within the stabilizer 7, and the bit body 4 is 19 inserted through openings in the drill stop member 5 and the stabilizer 7 whereby the drilling of a drill hole can be 21 effected. In doing so, the drill stop member 5, when in place, 22 abuts an interior portion 70 within the stabilizer 7 so as to 23 inhibit the downward movement of drill stop member 5 within the 24 stabilizer 7, thus restricting the drill bit (surrounded by the drill stop member 5) to achieving a pre-set cutting depth within 26 the drill hole 45. Of course, it will be understood that the 27 stabilizer 7, when positioned, will substantially surround the 28 drill hole 45, and, as shown in Figures 13A and 13B, a lower 29 portion 66 of the stabilizer 7 encircles and surrounds the drill hole 45, the lower portion having a greater outermost width than 31 that of the remainder of the stabilizer 7. It will of course be 1 understood that the dimensions of the stabilizer could be 2 varied, depending upon the size of the drill bit to be used. As 3 with the aforementioned embodiment of the seismic tool assembly 4 shown in Figure 12A, tilted rotational drilling of the drill stop member 5 within the stabilizer 7 is not to be effected, as 6 previously described. Rather, the drill stop member 5 within the 7 stabilizer 7 is rigid and does not have a range of tilted 8 rotation. Instead, when the seismic drilling bit is inserted, it 9 creates the drill hole 45 in a one-step process, and the circumference of the drill hole 45 at the lowermost end thereof 11 is the same circumference of the remainder of the drill hole 45.
12 As with the embodiment shown in Figures 13A, 13B and 14, 13 the stabilizer 7 further comprises an upper portion 68. However, 14 in this embodiment, the seismic assembly of the present invention further comprises locking means 40, which are 16 positioned substantially around the upper portion 68 of the 17 stabilizer 7 for selectively stabilizing the seismic drilling 18 bit and for preventing, when the locking means are engaged, 19 disassembly of the seismic drilling bit from the drill stop member 5 and the stabilizer 7. In a preferred embodiment, as 21 shown in Figure 15, the locking means 40 is a substantially 22 circular ring which at least partially encircles the upper 23 portion 68 of the stabilizer 7, the locking means 40 being 24 slidably movable to restrict disengagement of the seismic drilling bit from the stabilizer 7 and the drill stop member 5 26 mounted thereon.
27 It will be apparent to those skilled in this art that 28 various modifications and variations may be made to the 29 embodiments disclosed herein, consistent with the present 1 invention, without departing from the spirit and scope of the 2 present invention.
3 Other embodiments consistent with the present invention 4 will become apparent from consideration of the specification and the practice of the invention disclosed therein.
6 Accordingly, the specification and the embodiments are to 7 be considered exemplary only, with a true scope and spirit of 8 the invention being disclosed by the following claims.
Anchors are conventionally used in construction to attach 16 various components of a building construction to an overhead 17 ceiling or other structure. Such components to be attached can 18 relate to, for example, services that provide plumbing, 19 electrical, drainage, sprinkler system piping and drop ceilings.
From these anchors, which are usually of the wedge or drop-in 21 type variety, all of the above services and ceilings are 22 suspended or secured.
23 Conventionally, in setting anchors in concrete to suspend 24 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 26 inserted into the pre-drilled hole. However, when setting such 27 anchors in concrete it is not uncommon for such anchors to 28 weaken and loosen over time, particularly in situations where 29 cracking or chipping of the concrete around the pre-drilled hole has occurred.
1 Furthermore, studies have revealed that cracking can 2 typically occur in the concrete element, and that such cracks 3 can significantly impact the performance of anchors. Cracks can 4 originate on a concrete beam or slab in a variety of ways, such as creep, temperature settlement of the support or foundation, 6 thermal expansion and contraction stress overload, or from a 7 natural disaster such as an earthquake or flood. In such 8 situations, the situation can arise where, if one such concrete 9 anchor fails and lets go, the remaining anchors, by virtue of the weight they additionally assume in light of such failure, 11 can also similarly collapse and fail.
12 It has been found that enlarging the lowermost (interior) 13 portion of a drill hole can allow an anchor to be set more 14 securely therein. It has further been found that providing a drill hole with an enlarged lower end having a greater 16 circumference than that of the remainder of the drill hole can 17 be advantageously provided by a drill bit having an enlarged 18 cutting portion adjacent the tip, which is inserted into the 19 drill hole, whereby the enlargement of the cutting portion is configured so that it can pass through the shaft of the pre-21 drilled hole to be enlarged.
23 It would therefore be advantageous to have an improved 24 seismic tool assembly meant to be used for the later insertion and setting of anchors into brittle materials such as concrete, 26 stone, masonry and cementuous materials.
28 it would be further advantageous to have an improved 29 seismic tool assembly for use in a one step process for both creating a drill hole and, at the same time, enlarging a 31 lowermost end of a drill hole, wherein the lowermost end of the l drill hole can be further drilled and enlarged to have a greater 2 circumference than that of the remainder of the drill hole, 3 wherein an anchor can later be positioned and securely retained 4 within the enlarged area.
6 It would also be further advantageous to have an improved 7 seismic tool assembly meant to be used for the later insertion 8 and setting of anchors which utilizes a stabilizer having an 9 opening corresponding with the drill hole for receiving an insertion of the bit body into the drill hole, so as to aid in 11 accurately inserting the drill bit into the drill hole. It would 12 also be still further advantageous to have a stabilizer which 13 possesses a tapered interior, with an upper end of the 14 stabilizer having a narrower opening for receiving the insertion of the bit body therein and thus stabilize the bit body, and the 16 lower end of the stabilizer having a larger sized opening 17 greater than that of the upper end, so as to increase the range 18 of motion of the drilling bit and permit limited tilting 19 movement of the bit within the stabilizer during the drilling process so as to further aid in enlarging a lowermost end of the 21 drill hole to receive an anchor. To this end, the present 22 invention effectively addresses this need.
26 The present invention provides an improved seismic tool 27 assembly meant to be used for the later insertion and setting of 28 anchors for the insertion and setting of anchors into brittle 29 materials such as concrete, stone, masonry and cementuous materials.
32 The present invention also provides an improved seismic 33 tool assembly meant to be used for the later insertion and 1 setting of anchors, which can be used in a one step process for 2 both creating a drill hole and, at the same time, for enlarging 3 a lowermost end of a drill hole to have a greater circumference 4 than that of the remainder of the drill hole, whereby an anchor can be later set and positioned more securely therein.
7 The present invention also provides an improved seismic 8 tool assembly meant to be used for the later insertion and 9 setting of anchors which utilizes a stabilizer having an opening corresponding with the drill hole for receiving an insertion of 11 the bit body into the drill hole, so as to aid in accurately 12 inserting the drill bit into the drill hole.
14 The present invention also provides an improved seismic tool assembly meant to be used for the later insertion and 16 setting of anchors which utilizes a drill stop member which 17 possesses a tapered interior, with an upper end of the drill 18 stop member having a narrower opening for receiving the 19 insertion of the bit body therein and thus stabilize the bit body, and the lower end of the drill stop member having a larger 21 sized opening greater than that of the upper end, so as to 22 increase the range of motion of the drilling bit and permit 23 limited tilting movement of the bit within the drill stop member 24 during the drilling process so as to further aid in enlarging a lowermost end of the drill hole.
27 According to a first broad aspect of an embodiment of the 28 present invention, there is disclosed a seismic tool assembly 29 for effecting a drill hole and enlarging a lowermost end thereof for a later insertion and setting of anchors therein, 31 the assembly comprising a substantially cylindrical bit body 32 sized to fit into the drill hole, the bit body having a first 1 end region constructed and arranged to be operatively connected 2 to a drill and a second end region disposed generally opposite 3 said first end region, wherein a cutting portion is positioned 4 to protrude from at least one side of the second end region, the cutting portion having an operational cutting radius greater 6 than a cutting radius of the bit body; a drill stop member 7 having an opening defined therethrough corresponding with the 8 drill hole and for receiving an insertion of the bit body into 9 the drill hole; and a stabilizer for mounting within at least a portion of the drill hole and constructed and arranged for 11 having the drill stop member mounted thereon, the stabilizer 12 having a central opening corresponding with each of the openings 13 of the drill stop member and the drill hole, the stabilizer 14 restricting downward drilling movement of the bit body into the drill hole to a pre-set depth.

11 According to another aspect of the present invention, there 12 is provided a seismic tool assembly for effecting a drill hole 13 for a later insertion and setting of anchors therein, the 14 assembly comprising a substantially cylindrical bit body sized to fit into the drill hole, the bit body having a first end 16 region. constructed and arranged to be operatively connected to a 17 drill and a second end region disposed generally opposite said 18 first end region, wherein a cutting portion is positioned to 19 protrude from at least one side of the second end region, the cutting portion having an operational cutting radius greater 21 than a. cutting radius of the bit body; a drill stop member 22 having an opening defined therethrough corresponding with the 23 drill hole and for receiving an insertion of the bit body 24 therethrough; a stabilizer for mounting within at least a portion of the drill hole and having a recessed interior portion 26 which is constructed and arranged for having the drill stop 27 member mounted thereon, the stabilizer having a central opening 28 corresponding with each of the openings of the drill stop member 29 and further comprising:a bottom portion constructed and arranged to substantially surround the drill hole, the bottom portion 31 having an internally threaded opening at a lowermost surface 1 thereof; and a flange portion constructed and arranged to extend 2 into the drill hole and abut an inside portion thereof, an upper 3 end of the flange portion being threaded so as to permit 4 threaded engagement of the flange portion to the threaded internally threaded opening of the bottom portion.
6 An important advantage of the present invention is that it 7 provides an improved seismic tool assembly having a drill bit 8 which can be connected to a conventional drill, for effecting a 9 drill hole and enlarging a lowermost end thereof wherein an anchor can later be positioned and securely retained within the 11 enlarged area. Further, the present invention provides a 12 stabilizer for mounting within at least a portion of the drill 13 hole, having an opening corresponding with the drill hole, for 14 receiving an insertion of the drill bit into the drill hole, so as to aid in accurately inserting and positioning the drill bit 16 into the drill hole.
18 Another important advantage of the present invention is 19 that it provides an improved seismic tool assembly which utilizes a drill stop member which possesses a tapered interior, 21 with an upper end of the drill stop member having a narrower 22 opening for receiving the insertion of the bit body therein and 23 thus stabilize the bit body, and the lower end of the drill stop 24 member having a larger sized opening greater than that of the upper end, so as to increase the range of motion of the drilling 26 bit and permit limited tilting movement of the bit within the 27 drill stop member during the drilling process so as to further 28 aid in enlarging a lowermost end of the drill hole.

The invention will be described for the purposes of 16 illustration only in connection with certain embodiments;
17 however, it is to be understood that other objects and 18 advantages of the present invention will be made apparent by the 19 following description of the drawings according to the present invention. While a preferred embodiment is disclosed, this is 21 not intended to be limiting. Rather, the general principles set 22 forth herein are considered to be merely illustrative of the 23 scope of the present invention and it is to be further 24 understood that numerous changes may be made without straying from the scope of the present invention.
26 The present invention consists of an improved seismic tool 27 assembly designed for effecting a drill hole and enlarging a 28 lowermost end thereof to have a greater circumference than that 1 of the remainder of the drill hole whereby an anchor can be set 2 more securely therein.
3 Referring to Figure 9, there is shown a seismic tool 4 assembly for use in the later insertion and setting of anchors shown generally at 1 in accordance with a first exemplary 6 embodiment of the present invention. In a preferred embodiment, 7 as hereinafter described, the seismic tool assembly 1 is to be 8 rotatably mounted onto a drill by way of a drill spindle (not 9 shown). It will be understood that there are numerous variations as to the types of attachments to a drill or otherwise that the 11 seismic tool assembly 1 of the present invention could be 12 mounted thereon, as would be readily apparent to one skilled in 13 the art.
14 In a preferred embodiment, the seismic tool assembly 1 is for use in the later insertion and setting of anchors into 16 concrete, stone, masonry and cementuous materials (though it 17 will be understood that other variations to this are possible) 18 and comprises a seismic drilling bit 2, a stabilizer 7, and a 19 drill stop member 5, as hereinafter described.
Preferably, the seismic drilling bit 2 will be made of a 21 durable, machinable metal and is substantially cylindrical in 22 shape. The seismic drilling bit 2 is, preferably, of a one-piece 23 construction that comprises an upper end 9 and a lower end 8 24 which are integrally connected to one another.
With reference to Figure 1, it can be seen that the bit 26 body 4 of the seismic drilling bit 2 can effect the drilling of 27 a drill hole, and has a first diameter (and cutting radius) 28 sized to readily fit into a drill hole (not shown), and 29 possesses, as most conventional drill bits do, at least one 1 cutting edge and at least one groove extending in a helical 2 fashion along a length of the bit body 4 of the seismic drilling 3 bit 2. In a preferred embodiment, these extend along a 4 substantial length of the bit body 4, or, alternatively, extend along at least half a length of the bit body 4. Preferably, the 6 first diameter of the upper end 9 of the bit body 4 is less than 7 or equal to a diameter of the drill hole into which the seismic 8 drilling bit 2 of the present invention is to be inserted.
9 The proximal upper end 9 of the seismic drilling bit 2 is constructed and arranged to be releasably secured to a drill by 11 way of a drill spindle (not shown). In an alternative 12 embodiment, the distal lower end 8 of the seismic drilling bit 2 13 can have a tapered end (not shown) and a drill tip 11 extending 14 generally outwardly from the tapered end.
The lower end 8 of the seismic drilling bit 2 has a cutting 16 portion 10 positioned on each side of the lower end 8 of the 17 seismic drilling bit 2, the cutting portions 10 having a greater 18 outermost width than that of the bit body 4 whereby, when the 19 seismic drilling bit 2 is inserted fully into an lowermost end of the drill hole and rotated, the cutting portions 10 enlarge a 21 circumference of the drill hole at the lowermost end thereof 22 that is greater than the circumference of the remainder of the 23 shaft of the drill hole. Preferably, the cutting portions 10 24 extend outwardly from substantially around an entirety of the lower end 8 of the seismic drilling bit 2, as seen in Figure 1.
26 In an alternative embodiment (which is not shown), the lower end 27 8 of the seismic drilling bit 2 can have a cutting portion 28 positioned on only one side of the lower end 8 of the seismic 29 drilling bit 2.
1 In a still further embodiment (not shown), the bit body 4 2 of the seismic drilling bit 2 has a diameter (and cutting 3 radius) that is less than that of the drill hole, with the 4 cutting portions 10, of course, still having a greater outermost width (and cutting radius) than that of the bit body 4. In this 6 manner, with the bit body 4 of the seismic drilling bit 2 having 7 a width that is less than that of the drill hole, the initial 8 insertion of the seismic drilling bit 2 into the drill hole is 9 made easier, whereby the bit does not need to be as readily forcibly inserted.
11 With reference to Figure 2, the drill stop member 5, 12 preferably, has an opening 6 defined therethrough, and is used 13 for receiving an insertion of the seismic drilling bit 2. Figure 14 2 illustrates the upper end 30 of the drill stop member 5 having a shape which corresponds substantially to a shape of the 16 cutting portion 10 of the bit body 2 for receiving the insertion 17 of the bit body therethrough. With reference to Figure 3, it can 18 be seen that the lower end 32 of the drill stop member 5 has an 19 opening greater than that of the upper end 30, so as to permit limited tilting movement of the bit body from its vertical axis 21 within the drill stop member 5 during the drilling process to 22 further enlarge a lowermost end of the drill hole, it being 23 understood that this tilting rotational drilling of the lower 24 end of the drill hole by the drill bit 2 within the drill stop member 5 can be done through 360 degrees. This rotational 26 movement can be seen with reference to Figure 11, whereby the 27 lower end of the drill hole 45 can be seen to be funnel-shaped, 28 for receiving anchors therein.
29 Preferably, the opening in the drill stop member 5 is positioned at a substantially central location of the drill stop 1 member 5. The drill stop member 5 aids in the accurate and 2 gradual insertion of the seismic drilling bit 2 into the drill 3 hole. The drill stop member 5 further comprises a dust exit 4 opening 3 defined therein for allowing dust to be removed from the assembly during the drilling process, the dust exit opening 6 3 being positioned at substantially a middle portion of the 7 drill stop member 5. It will, of course, also be understood that 8 the stabilizer 7 could also possess such a dust exit opening.
9 The seismic tool assembly 1 further comprises, with reference to Figures 4 to 7, a stabilizer 7 for receiving, and 11 having mounted thereon, the drill stop member 5. The stabilizer 12 7 comprises a flange portion 15 constructed and arranged to 13 extend into the drill hole and abut an inside portion thereof.
14 In an alternative embodiment (not shown), the flange portion 15 of the stabilizer 7 could be tapered at a distal end thereof so 16 as to further aid in the accurate and gradual insertion of the 17 seismic drilling bit 2 into the drill hole. In a preferred 18 embodiment, and with reference to Figure 6, side portions of the 19 flange portion 15 have an elongated opening 44 defined along a length thereof, for allowing passage of the cutting portion of 21 the bit body when the bit body is inserted through the 22 stabilizer 7.
23 The stabilizer 7 further comprises an upper portion 34 24 integrally connected to the flange portion 15, the upper portion 34 having, with reference to Figure 7, a recessed upper surface 26 36 for receiving the drill stop member 5 mounted thereon. With 27 further reference to Figure 4, it can be seen that the central 28 opening 38 on the stabilizer 7 has a shape which corresponds 29 substantially to a shape of the cutting portion 10 of the bit 1 body for receiving, and allowing therethrough, the insertion of 2 the seismic drilling bit 2.
3 Preferably, the stabilizer 7 has the central opening 38 4 which corresponds with each of the openings of the drill stop member 5 and the drill hole, it being understood that the drill 6 stop member 5 restricts downward drilling movement of the 7 seismic drilling bit 2 into the drill hole to a pre-set depth, 8 through virtue of the bit body 4 of the seismic drilling bit 2 9 only being able to be pushed downwardly within the drill stop member 5 (mounted on the stabilizer 7) to a certain point, at 11 which it comes into contact with the drill stop member 5, thus 12 restricting its downward movement.
13 The seismic assembly of the present invention further 14 comprises locking means 40, which are positioned substantially around the flange portion 15 of the stabilizer 7 for selectively 16 stabilizing the seismic drilling bit 2 and for preventing 17 disassembly of the seismic drilling bit 2 from the drill stop 18 member 5 and the stabilizer 7. In a preferred embodiment, the 19 locking means 40 is a substantially circular ring which at least partially encircles an outside of the flange portion 15, the 21 locking means 40 being slidably movable to restrict 22 disengagement of the seismic drilling bit 2 from the stabilizer 23 7 and the drill stop member 5 mounted thereon. Figure 4 24 illustrates the locking means 40 in a substantially open position to receive an insertion of the bit body 2 therethrough, 26 and Figure 5 illustrates the locking means 40 in a substantially 27 closed position, having been slightly rotated so as to cover the 28 elongated opening 44 in the side portions of the flange portion 29 15, and thus restrict the disengagement of the bit body 2 from the interconnected drill stop member 5 and stabilizer 7. The 1 interconnection of the stabilizer 7 to the drill stop member 5 2 can be plainly seen in Figure 8.
3 In operation, and as seen in Figure 10, the drill stop 4 member 5 is mounted upon the stabilizer 7, and the seismic drilling bit 2 is inserted through the openings in the drill 6 stop member 5 and the stabilizer 7. Of course, seismic drilling 7 bit 2 is to be rotatably mounted onto a drill (not shown), and 8 the assembly is positioned over a surface where a drill hole is 9 to be made. Once the seismic drilling bit 2 is sunk to a pre-set depth and rotated, rotational drilling (and tilted rotational 11 drilling as previously described) by the seismic drilling bit 2 12 can then be effected in creating an enlarged area of the 13 lowermost end of a drill hole.
14 Of course, by virtue of the cutting portions 10 having an outermost width (and operational cutting radius) that is 16 slightly greater than that of the bit body 4, these cutting 17 portions 10, when the seismic drilling bit 2 is rotated, enlarge 18 a circumference of the drill hole at the lowermost end (in 19 creating the enlarged area) that is greater than that of the remainder of the drill hole. In this manner, once the enlarged 21 area has been created, and the seismic drilling bit 2 removed 22 from the drill hole, the anchor (not shown) can be inserted, 23 and, when the anchors have been flanged outwardly by 24 conventional means within the drill hole, the flange portions of the anchor can rest within the enlarged area, thus securely 26 retaining the anchor in place.
27 In a still further embodiment (not shown) the bit body 4 of 28 the seismic drilling bit 2 can be tapered, to have a narrower 29 circumference than that of the lowermost end of the bit body. In this manner, the tapered drill bit allows for less physical 1 contact with the drill stop member 5 and increases the range of 2 motion of the seismic drilling bit 2 in permitting limited 3 tilting movement of the bit to enlarge a lowermost end of the 4 drill hole 45. It will also be understood that the seismic drilling bit 2 can come in several set depths, or the drill stop 6 member 5 itself could be adjustable through a locking screw.
7 In a still further embodiment (not shown), the drill stop 8 member 5 is integrally mounted upon the stabilizer 7, and the 9 seismic drilling bit 2 is inserted through the openings in the drill stop member 5 and the stabilizer 7. In this manner, the 11 drill stop member 5 is permanently connected and un-detachably 12 mounted upon the stabilizer 7, and the seismic drilling bit 2 is 13 permanently inserted through the openings of the drill stop 14 member 5 and the stabilizer 7 so as to be of a permanently connected one-piece construction.
16 In a still further embodiment of the fully connected 17 seismic tool assembly, shown in Figure 12B, the drill stop 18 member 5 is mounted upon the stabilizer 7, and the bit body 2 is 19 inserted through the openings in the drill stop member 5 and the stabilizer 7 whereby the drilling of a drill hole can be 21 effected. Of course, it will be understood that the stabilizer 22 7, when positioned within the drill hole, helps to maintain the 23 integrity of the drill hole by virtue of flange portion 15 (as 24 shown in Figure 9), which is constructed and arranged to extend into the drill hole 45 and abut an inside portion thereof.
26 As shown in Figure 12B, the stabilizer 7 further comprises 27 an upper portion 34. This upper portion 34, as can be seen in 28 Figure 8, has an outermost width that is greater than that of 29 the flange portion 15. This upper portion 34 receives the drill stop member 5 mounted thereon, as similarly shown in Figure 8.
1 In this embodiment, the drill stop member 5 possesses a 2 lower portion 56, a recessed middle portion 58 and an upper 3 portion 60, all of which are, in an exemplary embodiment, 4 integrally connected together, though of course variations to this are possible, as these could potentially be interconnected.
6 As can be seen in Figure 12B, the lower portion 56 and the upper 7 portion 60 have an outermost width that is substantially equal, 8 while each of the lower portion 56 and the upper portion 60 have 9 an outermost width that is greater than that of the recessed middle portion 58.
11 In a further embodiment, the upper portion 34 of the 12 stabilizer 7 will have holding screws 54 connected thereto, 13 which are positioned at opposed sides of the upper portion 34 14 approximately at a same height as the recessed middle portion 58 of the drill stop member 5. These holding screws 54 can either 16 be turned and adjustably moved towards the recessed middle 17 portion 58 of the drill stop member 5 (so as to maintain the 18 connection of the drill stop member 5 to the stabilizer 7 during 19 a drilling process), or adjustably movable away from the recessed middle portion of the drill stop member so as to permit 21 disengagement of the drill stop member from the stabilizer.
22 Of course, as with the aforementioned embodiment of the 23 seismic tool assembly shown in Figure 1, the lower end 8 of the 24 bit body 4 has a cutting portion 10 positioned on each side of the lower end 8 of the bit body 4, the cutting portions 10 26 having a greater outermost width than that of the bit body 4.
27 When the seismic drilling bit is inserted, it creates the drill 28 hole 45 in a one-step process, and it will also be understood 29 that, in a still further embodiment, rotational drilling (and tilted rotational drilling as previously described) by the 1 seismic drilling bit 2 can also be effected in creating an 2 enlarged area of the lowermost end of a drill hole 45, creating 3 a funnel, conical shape in the drill hole 45. In a further 4 embodiment, the bit body 4 can possess a narrower circumference towards a lowermost end of the bit than that of the uppermost 6 end of the bit body. In this manner, the drill bit allows for 7 less physical contact with, particularly, the flange portion 15 8 of the stabilizer 7 and increases the range of motion of the 9 seismic drilling bit 2, when tilted, to provide a greater range of tilting movement of the bit in enlarging a lowermost end of 11 the drill hole 45.
12 A still further embodiment of the fully connected seismic 13 tool assembly is shown in Figure 12A. In a similar manner to the 14 embodiment shown in Figure 15, the drill stop member 5 is mounted within the stabilizer 7, and the bit body 4 is inserted 16 through openings in the drill stop member 5 and the stabilizer 7 17 whereby the drilling of a drill hole can be effected. In doing 18 so, the drill stop member 5, when in place, abuts an interior 19 portion 70 within the stabilizer 7 so as to inhibit the downward movement of drill stop member 5 within the stabilizer 7, thus 21 restricting the drill bit 4 (surrounded by the drill stop member 22 5) to achieving a pre-set cutting depth within the drill hole 23 45. Of course, it will be understood that the stabilizer 7, when 24 positioned, will substantially surround the drill hole 45, and, as shown in Figure 12A, a lower portion of the stabilizer 7 26 encircles and surrounds the drill hole 45, the lower portion 27 having a greater outermost width than that of the remainder of 28 the stabilizer 7. It will of course be understood that the 29 dimensions of the stabilizer 7 could be varied, depending upon the size of the drill bit to be used. Unlike the embodiment 31 shown in Figure 12B, however, tilted rotational drilling of the 1 drill stop member 5 within the stabilizer 7, as shown in Figure 2 12A, is not to be effected. Rather, the drill stop member 5 3 within the stabilizer 7 is rigid and does not have a range of 4 tilted rotation. Instead, when the seismic drilling bit is inserted, it creates the drill hole 45 in a one-step process, 6 and the circumference of the drill hole 45 at the lowermost end 7 thereof is the same circumference of the remainder of the drill 8 hole. Of course, it will also be understood that, in a still 9 further embodiment, rotational drilling (and tilted rotational drilling as previously described) by the seismic drilling bit 11 can also be effected in creating an enlarged area of the 12 lowermost end of a drill hole, in that the drill stop member 5 13 within the stabilizer 7 is not rigidly retained, so that when 14 the seismic drilling bit is inserted fully into a lowermost end of the drill hole 45 and rotated, the cutting portions 10 16 enlarge a circumference of the drill hole 45 at the lowermost 17 end thereof that is greater than the circumference of the 18 remainder of the shaft of the drill hole 45.
19 In a still further embodiment of the fully connected seismic tool assembly, shown in Figures 13A and 14, the drill 21 stop member 5 is mounted within the stabilizer 7, and the bit 22 body 4 is inserted through openings in the drill stop member 5 23 and the stabilizer 7 whereby the drilling of a drill hole can be 24 effected. In doing so, the drill stop member 5, when in place, abuts an interior portion 70 within the stabilizer 7 so as to 26 inhibit the downward movement of drill stop member 5 within the 27 stabilizer 7, thus restricting the drill bit (surrounded by the 28 drill stop member 5) to achieving a pre-set cutting depth within 29 the drill hole 45. Of course, it will be understood that the stabilizer 7, when positioned, will substantially surround the 31 drill hole 45, and, as shown in Figure 13A, a lower portion 66 1 of the stabilizer 7 encircles and surrounds the drill hole 45, 2 the lower portion having a greater outermost width than that of 3 the remainder of the stabilizer 7. It will of course be 4 understood that the dimensions of the stabilizer could be varied, depending upon the size of the drill bit to be used.
6 Of course, as with the aforementioned embodiment of the 7 seismic tool assembly shown in Figure 12A, tilted rotational 8 drilling of the drill stop member 5 within the stabilizer 7 is 9 not to be effected. Rather, the drill stop member 5 within the stabilizer 7 is rigid and does not have a range of tilted 11 rotation. Instead, when the seismic drilling bit is inserted, it 12 creates the drill hole 45 in a one-step process, and the 13 circumference of the drill hole 45 at the lowermost end thereof 14 is the same circumference of the remainder of the drill hole 45.
In an alternative embodiment of the fully connected seismic 16 tool assembly, shown in Figure 13B, the drill stop member 5 is 17 mounted upon the stabilizer 7, and the bit body 2 is inserted 18 through the openings in the drill stop member 5 and the 19 stabilizer 7 whereby the drilling of a drill hole can be effected. In this embodiment, the stabilizer 7 possesses flange 21 portion 15 (similar to the embodiment shown in Figure 9), which 22 is constructed and arranged to extend into the drill hole 45 and 23 abut an inside portion thereof. In this embodiment, the lower 24 portion 66 of the stabilizer 7 possesses threads on an interior surface thereof which can be matingly engaged with similar 26 threads contained towards an uppermost end of flange portion 15.
27 When disengagement of the lower portion 66 of the stabilizer 7 28 and flange portion 15 is desired, the threaded portions of each 29 can be untightened so as to permit disengagement of the flange portion 15 from the stabilizer 7. In this manner, a user can l utilize the tilted rotational drilling of the drill stop member 2 5 within the stabilizer 7, as shown in Figure 13B, or, simply 3 remove the flange portion 15 with a view to utilizing non-4 rotational drilling of the drill stop member 5 within the stabilizer 7, as shown in Figure 13A, whereby the drill stop 6 member 5 within the stabilizer 7 is rigid and does not have a 7 range of tilted rotation. It will be understood that flange 8 portion 15 will serve to limit somewhat the extent to which 9 rotational drilling can be effected, and thus protect the walls of the drill hole 45, as the bit 2 will contact the flange 11 portion 15 if the range of rotation is too great.
12 Of course, as with the aforementioned embodiment of the 13 seismic tool assembly shown in Figure 12B, when the seismic 14 drilling bit is inserted, it creates the drill hole 45 in a one-step process, and it will also be understood that, in a still 16 further embodiment, rotational drilling (and tilted rotational 17 drilling as previously described) by the seismic drilling bit 18 body 4 can also be effected in creating an enlarged area of the 19 lowermost end of a drill hole 45, creating a funnel, conical shape in the drill hole 45. In a further embodiment, the bit 21 body 4 can possess a narrower circumference towards a lowermost 22 end of the bit than that of the uppermost end of the bit body.
23 In this manner, the drill bit allows for less physical contact 24 with, particularly, the flange portion 15 of the stabilizer 7 and increases the range of motion of the seismic drilling bit, 26 when tilted, to provide a greater range of tilting movement of 27 the bit in enlarging a lowermost end of the drill hole 45.
28 As shown in Figures 13A, 13B and 14, the stabilizer 7 29 further comprises an upper portion 68. This upper portion 68, as can be seen in Figure 14, has an outermost width that is greater 1 than that of the interior portion 70, and posesses threads 72 2 towards an uppermost end thereof. With reference to Figure 14, 3 cap portion 74, which also possesses threads on an interior 4 surface thereof (not shown) can be matingly engaged with the threads of upper portion 68 so as to secure the upper portion 68 6 to the cap portion 74, thus securing the drilling assembly 7 together, in an exemplary embodiment, though of course 8 variations to this are possible. The cap portion will, in an 9 exemplary embodiment, have an opening defined therethrough (not shown) for receiving an insertion of the bit body therethrough, 11 which corresponds with the central opening of the stabilizer 7.
12 When disengagement of the upper portion 68 and cap portion 74 is 13 desired, the threaded portions of each can be untightened so as 14 to permit disengagement of the drill stop member 5 from the stabilizer 7.
16 In a still further embodiment of the fully connected 17 seismic tool assembly, shown in Figure 15, the drill stop member 18 5 is mounted within the stabilizer 7, and the bit body 4 is 19 inserted through openings in the drill stop member 5 and the stabilizer 7 whereby the drilling of a drill hole can be 21 effected. In doing so, the drill stop member 5, when in place, 22 abuts an interior portion 70 within the stabilizer 7 so as to 23 inhibit the downward movement of drill stop member 5 within the 24 stabilizer 7, thus restricting the drill bit (surrounded by the drill stop member 5) to achieving a pre-set cutting depth within 26 the drill hole 45. Of course, it will be understood that the 27 stabilizer 7, when positioned, will substantially surround the 28 drill hole 45, and, as shown in Figures 13A and 13B, a lower 29 portion 66 of the stabilizer 7 encircles and surrounds the drill hole 45, the lower portion having a greater outermost width than 31 that of the remainder of the stabilizer 7. It will of course be 1 understood that the dimensions of the stabilizer could be 2 varied, depending upon the size of the drill bit to be used. As 3 with the aforementioned embodiment of the seismic tool assembly 4 shown in Figure 12A, tilted rotational drilling of the drill stop member 5 within the stabilizer 7 is not to be effected, as 6 previously described. Rather, the drill stop member 5 within the 7 stabilizer 7 is rigid and does not have a range of tilted 8 rotation. Instead, when the seismic drilling bit is inserted, it 9 creates the drill hole 45 in a one-step process, and the circumference of the drill hole 45 at the lowermost end thereof 11 is the same circumference of the remainder of the drill hole 45.
12 As with the embodiment shown in Figures 13A, 13B and 14, 13 the stabilizer 7 further comprises an upper portion 68. However, 14 in this embodiment, the seismic assembly of the present invention further comprises locking means 40, which are 16 positioned substantially around the upper portion 68 of the 17 stabilizer 7 for selectively stabilizing the seismic drilling 18 bit and for preventing, when the locking means are engaged, 19 disassembly of the seismic drilling bit from the drill stop member 5 and the stabilizer 7. In a preferred embodiment, as 21 shown in Figure 15, the locking means 40 is a substantially 22 circular ring which at least partially encircles the upper 23 portion 68 of the stabilizer 7, the locking means 40 being 24 slidably movable to restrict disengagement of the seismic drilling bit from the stabilizer 7 and the drill stop member 5 26 mounted thereon.
27 It will be apparent to those skilled in this art that 28 various modifications and variations may be made to the 29 embodiments disclosed herein, consistent with the present 1 invention, without departing from the spirit and scope of the 2 present invention.
3 Other embodiments consistent with the present invention 4 will become apparent from consideration of the specification and the practice of the invention disclosed therein.
6 Accordingly, the specification and the embodiments are to 7 be considered exemplary only, with a true scope and spirit of 8 the invention being disclosed by the following claims.
