Description

ANCHOR INSTALLATION TOOL

The present disclosure relates to masonry construction and, more particularly, to a tool to install anchors and nails in masonry concrete or the like.

In the past, various types of anchor installation tools have been used.

Ordinarily, a drill is used to form a hole in the concrete or masonry structure. The anchor is inserted into the bore. After that, a hammer is utilized to pound the anchor into the masonry material. While this application is satisfactory, it is time consuming and very demanding on the user. In fact, when anchors are to be inserted overhead, the user must pound upwardly with a hammer in order to sink the anchor into the structure. This is very demanding on the body of the user.

Other types of percussion tools are in the art. These tools enable a drill to be positioned into a hammer bit for drilling a bore into the concrete material. A beat piece is positioned on top of the drill in order to utilize the hammer drill to secure the anchor into the concrete or masonry material. While these tools function satisfactory for their intended purpose, designers strive to improve the art.

Accordingly, the present disclosure provides an anchor installation tool that eliminates the use of manual hammering. The present disclosure provides an anchor tool that is usable in tight spaces where the wielding of a hammer is difficult and time consuming. The present disclosure provides a simple yet effective tool to insert anchors into the concrete material. Additionally, the installation tool provides a guide to ensure proper alignment of the anchor in the bore.

In accordance with the disclosure, an anchor installation tool comprises an elongated member having a body portion, a head portion and a tail portion. The tail and body portions include openings to receive a drill bit. The head portion projects from the body portion. The head portion is coaxially with the body portion and includes a bore for receiving an anchor. The tail portion includes a first member to retain the anchor installation tool on a drill bit.

The tail portion further includes a holder to hold the body portion in the non-coaxial position. In the non-coaxial position, the body portion is substantially transverse to the axis of the drill bit. The tail portion comprises a socket with a cylindrical portion and yoke. The cylindrical portion includes an aperture to receive a ball that fits into a groove on the drill bit. A nut is positioned over the ball to maintain it in the groove. The yoke includes a pair of arms having a channel between the arms that enables the body portion to pivot through the channel. The body portion has an overall right circular cylinder design with a through channel providing the cylinder with a U-shaped cross section. The channel has a width to enable the drill bit to pass through the body portion when the body portion is moved between the coaxial and non-coaxial positions. The holder includes a U-shaped clip to receive the body portion.

In accordance with a second aspect of the disclosure, an anchor installation tool comprises an elongated body having an opening to receive a drill bit. A head is on the elongated body to receive an anchor. A socket is coupled with the elongated body. The socket includes an opening to receive the drill bit. The elongated body pivots on the socket from a first position to a second position. In the first position, the installation tool is capable of installing an anchor. In the second position, the anchor installation tool enables drilling. The socket has a cylindrical portion and yoke. The cylindrical portion includes an aperture to receive a ball that fits into a groove on the drill bit. A nut is positioned over the ball to maintain it in the groove. The yoke includes arms having a channel therebetween. The channel enables the body portion to pivot through the channel. The body has an overall right circular cylindrical design with a through channel providing the cylinder with a U-shaped cross-section.

The channel has a width to enable a drill bit to pass through the body portion when it is pivoted between positions.

In accordance with a third aspect of the disclosure, a method for setting an anchor comprises positioning the anchor installation tool onto a drill bit. The body portion is moved to a non-coaxial position. A hole is drilled into a structure. The body member is moved into a coaxial position with respect to the drill bit. An anchor is positioned into a head portion. Percussive movement is provided to the drill bit.

The anchor is driven into the structure. Additionally, a hammer drill is provided to drive the drill bit.

The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses.

Turning to the figures, an installation tool in accordance with the disclosure is illustrated and designated with the reference numeral 10. A hammer drill 12 is illustrated receiving the anchor installation tool 10. A nail-in anchor 14 is illustrated to be secured into a structure 16.

Moving to FIG. 2, the anchor installation tool 10 is illustrated. The installation tool 10 includes an elongated member 20 and an anchor guide 22. Additionally, the installation tool 10 can be combined with a drill bit 24. The drill bit 24 includes a fluted portion 26 as well as a chucking portion 28. A groove 30 is formed in the drill bit to assist in retaining the installation tool 10 onto the drill bit 24. The chucking portion 28 may include an SDS shank to be positioned into the hammer drill 12.

The elongated body 20 includes a shaft 32 and a socket member 34. The shaft 32 has an overall right cylindrical shape with a channel with an open side 36 providing the shaft 32 with an overall U-shape in cross section with two legs 38 and 40. The channel 36 has a width opposing the web that enables the drill bit 24 to be moved in and out of the channel 36. The shaft 32 includes a projecting head 42.

The head 42 projects substantially coaxially with the shaft 32. An extension member 43 projects from the head 42. The head 42 has a desired length and diameter.

Ordinarily, the head 42 is a solid portion. The opened end of the shaft 32 includes a bead 44 with an adjacent groove 45 that are received into the socket 34.

Additionally, the shaft 32 includes a pair of slots 46 and 48 on the legs 38 and 40.

Additionally, it includes a third slot 49 along the web to provide through aperture at the tail of the shaft 32. The slots 46, 48 enable the shaft 32 to be moved away from and pivot with respect to the socket 34 as will be explained herein.

The shaft 32 is generally made out of a metallic material such as steel. The junction with the extension member 43 forms a stop surface 50 at the end of the shaft 32. The stop surface 50 contacts a stop surface on the anchor guide 22 as will be explained later.

The anchor guide 22 has a sleeve-shaped body 52. The sleeve 52 includes an internal bore 54 that extends through the sleeve shaped body 52. The bore 54 includes a first portion 56, a reduced diameter portion 57, a second portion 58 and end portion 60. The first portion 56 is sized to fit over the shaft 32 of the elongated member 20. The reduced diameter portion 57 is sized to fit over the extension 43 projecting member 45. A stop 62 is formed at the transition between the two bore portions 56, 57. The stop 62 provides a surface that abuts against the surface 50 to stop further movement of the guide anchor 22 as it slides along shaft 32.

The second bore portion 58 is on the other side of the reduced diameter portion 57. The second portion 58 received an annular magnet 63 and spacer 65. The magnet assists in retaining the anchor in the tool 10. The magnet 63 is the sole retention member when a duplex or double head nail is used as the anchor. The spacer 65 positions the magnets 63 adjacent the reduced diameter portion 57. A C-clip 67, positioned in groove 69, holds the spacer 65 and magnet in the second bore portion 58.

An anchor receiving member 64 is at the end of the second bore portion 58 beyond groove 69. The receiving member 64 is an enlarged bore that receives the head of the anchor 14. With the nail portion of the anchor extending into the bore 58 adjacent the magnet 63, and its head captured in the receiving member 64 the anchor 14 is held in the anchor guide 22 so that it may be inserted into a bore in a concrete structure as seen in FIG. 6A.

The retention mechanism 70 includes a groove 72 a retaining clip 74 and a stop surface 76 on the anchor guide 22. The groove 72 is formed into the outer surface of the shaft 34. The groove 72 is circumferentially spaced about the extension member 43. A retention clip 74, generally a hog ring clip, is positioned onto the shaft 34, The retention clip 74 extends radially outwardly above the shaft 34 from the groove 72. Thus, the retaining clip 74 acts as a stop when the guide member 22 is slid forward on the extension 43 and the shaft 34. The stop surface 76 is formed at the junction of the first bore portion 56 and the end portion 60. The end portion 60 has a diameter slightly smaller than the first bore portion 56.

A chamfer 80 is formed at the end of the guide member 22. The chamfer 80 enables the guide member 22 to slide over top of the C-clip 74, compressing it radially inward to move over the C-clip 74 to retain the guide 22 on the shaft 34.

Thus, after an anchor is set into the concrete structure, the guide 22 is pulled forward, toward extension 43, on the shaft 34 until the stop surface 76 contacts the retention clip 74.

A socket 34 includes a body 90 having projecting yoke 92 and a cylindrical portion 94. The yoke 92 includes two arms 96 and 98 that each includes a pin 100 that is received in the slots 46, 48 of the shaft 32. The body 90 includes a circular recess 102 with a hog clip 104 to receive the bead 44 and capture the groove 45 to maintain the shaft inside of the body 90 of the socket 34.

Cylindrical portion 94 includes an aperture 106 to receive a ball 108. The ball 108 is positioned into the drill bit groove 30. A nut 114 includes an angled bore 118 to enable it to slide over the ball 108 to force it into and maintain the ball in the groove 30. Additionally, the cylindrical portion 94 includes an internal bore 110 that aligns the groove 30 on the drill bit 24 with the ball 108. A C-clip 116 secures onto the cylindrical portion 94 to maintain the nut 114 on the cylindrical portion 94.

A U-shaped holder or clip 120 is secured onto the socket 34. The clip 120 receives the shaft 32 when it is in a second or drill mode position as seen in FIG. 5.

As seen in FIG. 5, the clip 120 snaps around the shaft 32 to hold it in position when drilling a bore.

In use, the drill bit 24 is in inserted into the installation tool 10. The drill bit 24 is inserted into the installation tool 10 until the ball 108 is received in the groove. At that time, the nut 114 is pushed over the ball 108 to retain the installation 10 onto the drill bit 24. In a hammer mode, the shaft 32 is coaxial with the axis of the drill bit 24.

When drilling is to occur, the shaft 32 with the slots 46,48 sliding on the pins 100 and slot 49 receiving the drill bit 24. It is enabled to pivot into a non-coaxial position as seen in Fig. 5. In fact, the holder 120 holds the shaft substantially transverse to the drill bit axis as illustrated in FIG. 5.

A method of using the anchor installation tool 10 is as follows. The anchor installation tool 10 is secured onto the drill bit 24 by pushing the nut 114 over the ball 108 locking it in the groove 30. The shaft 32 is pulled away from the socket 34 and is positioned into a non-coaxial position with respect to the drill bit 24. A hole or bore is drilled into the concrete structure 16 to a desired depth as illustrated in FIG. 6a. The shaft 32 is pivoted back into a coaxial position and pushed downward into the socket 34. Additionally, the glide member 22 is extended so that the stop surface 66 engages the retention clip 64. A nail end type anchor 14 is positioned with a nail portion in the second bore portion adjacent the magnet and ahead of the insert in the receiving portion of the guide as seen in FIG. 6b. The anchor 14 is inserted into the concrete hole or bore as illustrated in FIG. 6b. At that time, the hammer drill is activated to percussively pound the nail end anchor into the structure. As this occurs, the nail is pounded into the concrete to spread the insert as illustrated in FIG. 6c. After the nail has been set, the anchor installation tool is removed from the nail and the drive guide 22 is positioned back over the head 38 of the elongated member ready for its next use.

Fig. 7 is a second embodiment of the anchor installation tool. The tool is the same as that previously described except the drive guide 22' is stationarily fixed to the shaft head 42. The drive guide 22' has a through bore 130. A first bore portion 132 is sized to friction fit onto the head 42 as seen in Fig. 7. A second reduced diameter bore portion 134 receives an annular plug 136 and magnet 138. A third bore portion 140 at the front of the installation tool relieves the nail in anchor. The magnet 138 holds the nail in anchor as it is hammered into the hole in the concrete structure.

The description of the invention is merely exemplary in nature and, thus, variations that do not depart from the gist of the invention are intended to be within the scope of the invention. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
