Abstract
A seismic drilling bit designed for insertion for use in enlarging an upper end of a pre-drilled hole for receiving and securely retaining an anchor therein. The bit is rotatably mounted onto a drill or can be mounted onto a mounting assembly which in turn is rotatably mounted to the drill. The bit also has a pivot ring which permits limited tilting movement of the bit body during a drilling process to enlarge the lowermost end of the drill hole. In this manner, an anchor can be inserted within the pre-drilled hole, and, when the anchor has been flanged outwardly by conventional means within the hole, the flange portions of the anchor will rest within the enlarged area, thus securely retaining the anchor in place.
Description
t t SEISMIC DRILLING BIT WITH PIVOT RING FOR USE IN ANCHOR
INSERTION
The present invention relates to a seismic drilling bit meant to be used for the insertion and setting of anchors, such as drop-in and wedge type anchors, and, more particularly, the present invention relates to a seismic drilling bit with a pivot ring for the insertion and setting of anchors into brittle materials such as concrete, stone, masonry and cementuous materials.
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.
a f 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 upper (interior) part of the pre-drilled hole can allow for the use of anchors in a more secure manner. It has further been found that providing a pre-drilled hole with an enlarged upper end can be advantageously provided by a drill bit having an enlarged cutting portion adjacent the tip, which is inserted into the pre-drilled hole, whereby the enlargement of the cutting portion is configured so that it can pass through the shaft of the pre-drilled hole to the upper end to be enlarged.
It would therefore be advantageous to have an improved seismic drilling bit meant for use in a pre-drilled hole for the 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 drilling bit 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 an anchor can later be positioned and securely retained within the enlarged area.
It would also be further advantageous to have an improved seismic drilling bit meant to be used for the later insertion and setting of anchors which utilizes a pivot ring for coming into contact with a surface being drilled and thus restricting downward movement of the seismic drill bit within the drill hole, the pivot ring having an outermost diameter greater than that of the drill hole and a remainder of the drill bit, whereby the pivot ring permits tilting movement of the bit body during a drilling process to enlarge the lowermost end of the drill hole.
To this end, the present invention effectively addresses this need.
SUMMARYOFTHEINVENTION
The present invention provides an improved seismic drilling bit meant for use in a pre-drilled hole for the insertion and setting of anchors into brittle materials such as concrete, stone, masonry and cementuous materials.
The present invention also provides an improved seismic drilling bit for use in enlarging an upper end of a pre-drilled hole, wherein an uppermost end of the pre-drilled hole can be further drilled to have a greater circumference than that of the remainder of the pre-drilled hole, whereby an anchor can be set more securely therein.
The present invention also provides an improved seismic drilling bit having a pivot ring for coming into contact with a surface being drilled and thus restricting downward movement of A
the seismic drill bit within the drill hole, the pivot ring having an outermost diameter greater than that of the drill hole and a remainder of the drill bit, whereby the pivot ring permits limited tilting movement of the bit body during a drilling process to enlarge the lowermost end of the drill hole.
According to a first broad aspect of an embodiment of the present invention, there is disclosed a seismic drill bit for effecting a drill hole and enlarging a lowermost end thereof for a later insertion and setting of anchors therein, the bit comprising a substantially cylindrical bit body sized to fit into the drill hole, the bit body having a first end region constructed and arranged to be operatively connected to a drill and a second end region disposed generally opposite said first end region, wherein a quad cutting portion is positioned to protrude from the second end region, the quad cutting portion having an operational cutting radius greater than a cutting radius of the bit body; and a pivot ring for coming into contact with a surface being drilled and thus restricting downward movement of the seismic drill bit within the drill hole, the pivot ring having an outermost diameter greater than that of the drill hole and a remainder of the drill bit, whereby the pivot ring permits limited tilting movement of the bit body during a drilling process to enlarge the lowermost end of the drill hole.
An important advantage of the present invention is that it provides an improved seismic drilling bit which can be connected to a conventional drill, meant for use in a pre-drilled hole for the insertion and setting of anchors into brittle materials such as concrete, stone, masonry and cementuous materials.
Another important advantage of the present invention is that it provides an improved seismic drilling bit having a pivot ring for coming into contact with a surface being drilled and thus restricting downward movement of the seismic drill bit within the drill hole, the pivot ring having an outermost diameter greater than that of the drill hole and a remainder of the drill bit, whereby the pivot ring permits limited tilting movement of the bit body during a drilling process to enlarge the lowermost end of the drill hole.

DETAILEDDESCRIPTIONOFTHEINVENTION
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 drilling bit designed for insertion and use in enlarging an upper end of a pre-drilled hole for receiving and securely retaining an anchor therein. The drilling bit which can be rotatably mounted onto a conventional drill, or, alternatively, onto an elongated mounting assembly, which in turn is rotatably mounted to a conventional drill.
Referring to Figure 1, there is shown a seismic drilling bit shown generally at 1 in accordance with a first exemplary embodiment of the present invention, for use in the later insertion and setting of anchors into concrete, stone, masonry and cementuous materials. In a preferred embodiment, the proximal upper end 5 of the seismic drilling bit 1 is , constructed and arranged to be releasably secured to a drill by way of a drill spindle (not shown). In this manner, the bit itself, without any other necessary parts, can be easily attached to a drill to effect the drilling of a drill hole and enlarging a lowermost end thereof, whereby an anchor can be set more securely therein.
Preferably, the seismic drilling bit 1 will be made of a durable, machinable metal and is substantially cylindrical in shape. The seismic drilling bit 1 is, preferably, of a one-piece construction that comprises an upper end 5 and a lower end 9 which are integrally connected to one another. The drilling bit 1 can also have a fluted body or a non-fluted body.
With reference to Figures 1, 2 and 3 it can be seen that the bit body 11 of the seismic drilling bit 1 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 11 of the seismic drilling bit 1. In a preferred embodiment, these extend along a substantial length of the bit body 11, or, alternatively, extend along at least half a length of the bit body 11.
The lower end 9 of the seismic drilling bit 1 has a quad cutting portion 13 positioned at the lowermost end of the seismic drilling bit 1, as seen in Figures 1, 2 and 3, the quad cutting portion 13 having a greater outermost width than that of the bit body 11 whereby, when the seismic drilling bit 1 is inserted fully into a lowermost end 43 of the drill hole 45 and , rotated during the drilling process (as shown in Figure 3), so as to effect a conical shape in the drill hole 45, the quad cutting portion 13 enlarge a circumference of the drill hole 45 at the lowermost end 43 thereof that is greater than the circumference of the remainder of the shaft of the drill hole 45.
With reference to Figures 1, 2 and 3, the seismic drilling bit 1 further comprises a pivot ring 14. As shown in Figures 2 and 3, when the drilling bit is used to effect a drilling hole 45 and is inserted further into the hole 45, the seismic drilling bit 1 (see Figure 2) can only be pushed downwardly to a certain point, at which the pivot ring 14 comes into contact with the surface being drilled, thus restricting further downward movement of the seismic drilling bit 1. Once the seismic drilling bit 1 is positioned into the hole 45, the seismic drilling bit 1 and pivot ring 14 can operably be rotated (by the user rotating the drill during the drilling process), as shown in Figure 3, to provide for wider rotation of the seismic drilling bit 1 inside the hole 45 with a view to enlarging a lowermost end 43 of the drill hole 45 to receive an anchor.
In operation, the seismic drilling bit 1 is to be rotatably mounted and connected onto a drill (not shown) by way of spindle 5, and the assembly is positioned over a surface where a drill hole is to be made. Once the seismic drilling bit 1 is sunk to a pre-set depth and rotated, rotational drilling (and tilted rotational drilling as previously described) by the seismic drilling bit 1 can then be effected in creating an enlarged area of the lowermost end of a drill hole. By virtue of pivot ring 14 the seismic drilling bit 1 (see Figures 2 and 3) can only be pushed downwardly to a certain point, at which the pivot ring 14 comes into contact with the surface being drilled, thus restricting further downward movement of the seismic drilling bit 1. Once the seismic drilling bit 1 is fully positioned into the hole 45, the seismic drilling bit 1 and pivot ring 14 can then operably be rotated (by the user rotating the drill during the drilling process), the pivot ring controlling the amount of rotational tilting during the drilling process, as shown in Figure 3, and providing for a greater range of rotation of the seismic drilling bit 1 inside the hole 45 with a view to enlarging a lowermost end 43 of the drill hole 45.
Of course, by virtue of the quad cutting portion 13 having a greater outermost width (and operational cutting radius) than that of the bit body 11, the quad cutting portion 13, when the seismic drilling bit 1 is rotated, enlarges a circumference of the drill hole 45 at the lowermost end 43 (in creating the enlarged area). In this manner, once the enlarged area has been created, and the seismic drilling bit 1 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.
