A fastener installation system comprising an SDS drill, an impact mechanism, an adapter, and a hammer socket. A method of installing a fastener into a receiving surface using an SDS drill. The method comprising the steps of drilling a hole in a receiving surface, hammering an anchor into the hole in the receiving surface, rotating the nut of the anchor towards a tightened position by using a socket mounted in the chuck of the SDS drill, and tightening the nut of the anchor by using a rotationally operable impact mechanism.

Description

FASTENER INSTALLATION SYSTEM AND METHOD
FIELD OF THE INVENTION
[0001] The present invention relates to SDS drills, and more particularly to installing fasteners with SDS drills.
BACKGROUND OF THE INVENTION
[0002] In construction, one of the most common operations is to install fasteners, such as threaded fasteners, into a receiving surface such as concrete, metal, wallboard, and so on. The operation of installing fasteners generally requires a hole to be drilled in the receiving surface, an anchor to be installed in the drill hole, and then the fastener be installed in place in the anchor within the drill hole.
[0003] Often, threaded fasteners must be installed into a surface of hard material, such as a concrete wall or floor. In this case, it is common to use an SDS type drill, as is well known in the industry. SDS drills are rotary hammer drills that have a chuck that concurrently provides rotational and hammering motion for a retained drill bit. The drill bits have a pair of slots therein, and are inserted into and slidably retained in a specifically designed chuck system that allows for limited longitudinal displacement of the retained drill bit, as caused by a hammer-action mechanism. This specific hammering action allows power to be directly, accurately and efficiently transferred to the drill bit.
[0004] Typically, it is undesirable to actually puncture the entire thickness or depth of the concrete walls or floors in order that they serve as a complete, or nearly complete, barrier. Therefore, the drill holes are over depth less than the thickness or depth of the concrete walls or floors. Accordingly, a nut or the like cannot be engaged onto the threaded lead end of the threaded fastener. In order to ensure that the threaded fastener is securely retained in the receiving surface, an anchor such as a wedge anchor is used.
[0005] In order to install a wedge anchor into a drill hole, it is initially manually inserted up part way into the drill hole. Subsequently, a hammer is used to carefully tap the wedge anchor into place. Unfortunately, this operation partly relies on the skill and strength of the worker, and also is fatiguing. Further, it is necessary to carry around and have immediately available a suitable hammer. Also, this operation can be quite time- consuming, especially considering that the worker must use the SDS drill and the hammer alternatingly, or in other words put down one tool and then pick up the other tool for every fastener/anchor pair that is to be installed.
[0006] It is an object of the present invention to provide a method of installing a fastener into a receiving surface.
[0007] It is an object of the present invention to provide a method of installing a fastener into a receiving surface, which receiving surface comprises a concrete wall or a concrete floor.
[0008] It is an object of the present invention to provide a method of installing a fastener into a receiving surface, which method employs an SDS drill.
[0009] It is an object of the present invention to provide a method of installing a fastener into a receiving surface, which method employs an SDS drill to drill the drill hole, employs an SDS drill to install the wedge anchor into the drill hole, and employs an SDS drill to turn the nut of the fastener to thereby advance the fastener further into the wedge anchor. [00010] It is an object of the present invention to provide a method of installing a fastener into a receiving surface, which method permits ready installation of a wedge anchor into a drill hole.
[00011] It is an object of the present invention to provide a method of installing a fastener into a receiving surface, which method does not involve the use of separate manually powered hammer.
[00012] It is an object of the present invention to provide a method of installing a fastener into a receiving surface, wherein the overall operation of drilling a hole in the receiving surface, installing and anchor into the drill hole, and turning a threaded fastener into the anchor is much less time-consuming than in the prior art.

RECTIFIED SHEET (RULE 91.1) rotationally operable impact mechanism 181 securely retained in the chuck 122 of an SDS drill 120 and invoking the rotational function of the SDS drill 120, step d) could comprise tightening the nut 113 of the anchor 114 by using a rotationally operable impact mechanism 181 driving a socket 150, step d) could comprise tightening the nut 3 of the anchor 114 by using a rotationally operable impact mechanism 181 driving a hex socket 160, and step d) could comprise tightening the nut 113 of the anchor 114 to a specified torque by using a rotationally operable impact mechanism 181.
[000112] It should be noted that the hammer socket 150 preferably hammers against the nut 113 of the wedge anchor 114.
[000113] Other variations of the above principles will be apparent to those who are knowledgeable in the field of the invention, and such variations are considered to be within the scope of the present invention. Further, other modifications and alterations may be used in the design and manufacture of the impact mechanism of the present invention without departing from the spirit and scope of the accompanying claims.
