## Background
FIELD
The present disclosure relates to an installation tool, and in particular, to an installation tool for installing an escutcheon for a fire protection sprinkler.
BACKGROUND
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
Fire protection sprinklers are commonly mounted to ceilings of residential and commercial buildings. Such sprinklers are often housed within an opening in the ceiling in such a manner that the sprinkler head protrudes below the surface of the ceiling. A decorative escutcheon may be installed in the opening in the ceiling around the sprinkler head, improving the aesthetic qualities of the sprinkler system. In response to heat, the sprinkler trigger mechanism is activated to allow the sprinkler to discharge water below the ceiling.
Typically, a worker must stand atop a ladder or scaffolding to reach the opening in the ceiling to install the escutcheon. When installing escutcheons over multiple sprinklers, the worker must then climb down from the ladder or scaffolding, move the ladder or scaffolding below the next sprinkler, and climb back up to install the next escutcheon, repeating this process for each of the sprinklers in a given building. This process is time-consuming and costly.

An end face 58 of the base 28 is disposed at an open end of the upper cavity 50 and may be generally perpendicular to the outer surface 42.
The markings 54 may include alpha-numeric text, symbols and/or lines printed, etched, or otherwise formed on the outer surface 42. For example, the base 28 may include markings 54 indicating a flush position, a 1⁄8 inch position, a 1⁄4 inch position, a 3⁄8 inch position, and a plurality of lines corresponding to each position. Each of the lines may be spaced apart in 1⁄8 inch increments. It should be appreciated that the base 28 could include any number of markings 54 at increments of any suitable spacing.
The sleeve 30 may be generally tubular and may include an inner surface 60, an outer surface 62, an annular flange portion 64, and a bottom edge 65. The inner surface 60 may include a plurality of interior threads 66 which may threadably engage the exterior threads 52 disposed on the outer surface 42 of the base 28 such that the base 28 is received within the inner surface 60 of the sleeve 30. In this manner, the sleeve 30 is selectively threadably movable relative to the base 28 along a longitudinal axis of the installation tool 10 through a plurality of positions, including the flush position, the 1⁄8 inch position, the 1⁄4 inch position, and the 3⁄8 inch position, for example.
The annular flange portion 64 of the sleeve 30 may include a recess 68 disposed around the inner surface 60. The recess 68 may releasably receive a rim portion 70 of the escutcheon 16, as shown in FIG. 3. In this manner, the base 28 is movable relative to the sleeve 30 and the escutcheon 16. The base 28 may be positioned such that the end face 58 of the base 28 may extend into a tubular portion 72 of the escutcheon 16, as shown in FIGS. 3 and 5-8. The base 28 can also be positioned such that the end face 58 is substantially flush with the upper surface of the rim portion 70 of the escutcheon 16, as shown in FIG. 4.
The extension member 14 may be an elongated rigid pole extending along the longitudinal axis of the installation tool 10 and may include an aperture 73 extending through a diameter of the extension member 14 generally perpendicular to the longitudinal axis X. The extension member 14 may also include one or more telescoping features 75, whereby the length of the extension member 14 may be expanded and/or contracted in the longitudinal direction as illustrated by arrow A in FIG. 1, to allow use with ceilings of various heights.
The extension member 14 may be received within the lower cavity 44 of the base 28, such that the apertures 46, 73 are disposed substantially concentric to each other (FIG. 3). In this configuration, a fastener 77 may be disposed through the apertures 46, 73, retaining the extension member 14 within the lower cavity 44. The fastener 77 may be threadably engaged with one or both of the apertures 46, 73 to retain the fastener 77 therein. Additionally or alternatively, the fastener 77 may be threadably engaged with a nut (not shown), for example, or the extension member 14 may be glued, press fit, threaded to or otherwise fixed to the body portion 12. The base 28 may be permanently fixed to the extension member 14 or integrally formed therewith.
Referring now to FIGS. 6-8, the sprinkler assembly 20 may include a sprinkler head 74, a water pipe 76, and a cup 78 adapted to engage the tubular portion 72 of the escutcheon 16. The water pipe 76 delivers water to the sprinkler head 74. The sprinkler head 74 may protrude through the opening 22 of the ceiling 24. The sprinkler head 74 sprays water into a room of the building in response to heat from a fire, for example.
The cup 78 may have a generally U-shaped cross section including a downward-facing surface 80 and an outer circumferential surface 82. The outer circumferential surface 82 may include one or more ribs 84 adapted to engage one or more protuberances 86 disposed on an inner diameter of the tubular portion 72 of the escutcheon 16, thereby retaining the escutcheon 16 to the sprinkler assembly 20. It should be appreciated that the escutcheon 16 could engage the sprinkler assembly 20 by other suitable means known in the art.
The cup 78 may be disposed around the sprinkler head 74, the water pipe 76, or may be otherwise suitably fixed to the sprinkler assembly 20 proximate the opening 22 in the ceiling 24. The cup 78 is disposed substantially concentric to the opening 22. The downward-facing surface 80 of the cup 78 may be substantially flush with an interior-facing surface 88 of the ceiling 24. Alternatively, the downward-facing surface 80 of the cup 78 could located at any distance from the interior-facing surface 88 of the ceiling 24 such as, for example, 1⁄8 inch, 1⁄4 inch, or 3⁄8 inch.
Referring now to FIGS. 1 and 4-8, operation of the installation tool 10 will be described in detail. The sleeve 30 may be threadably engaged with the base 28, as described above. The operator 18 may adjust the sleeve 30 relative to the base 28 to selectively arrange the body portion 12 in one of the plurality of positions indicated by the markings 54 by aligning the bottom edge 65 of the sleeve 30 with one of the lines corresponding to the Flush position, the 1⁄8′′ position, the 1⁄4′′ position, or the 3⁄8′′ position. The operator 18 may select the position of the sleeve 30 relative to the base 28 based on the distance between the interior-facing surface 88 of the ceiling 24 and the downward-facing surface 80 of the cup 78. For example, if the interior-facing surface 88 is flush with the downward-facing surface 80, the operator 18 can move the sleeve 30 into the Flush position (FIG. 4). If the interior-facing surface 88 is disposed at a distance of 3⁄8′′ from the downward-facing surface 80, the operator 18 can move the sleeve into the 3⁄8′′ position (FIG. 5), for example.
The sleeve 30 may engage the escutcheon 16 such that the rim portion 70 is received within the recess 68 of the sleeve 30. It should be appreciated that the escutcheon 16 may be received within the sleeve 30 either before or after the operator 18 selects the appropriate position of the sleeve 30 relative to the base 28.
As shown in FIG. 1, the operator 18 may grasp the extension member 14 and raise the body portion 12 (with the escutcheon 16 releasably retained thereon) towards the sprinkler assembly 20 in the ceiling 24. The operator 18 then aligns the escutcheon 16 below the sprinkler assembly 20 along the longitudinal axis of the installation tool 10, as shown in FIG. 6. Next, an upward force F1 may be applied to the extension member 14 along the longitudinal axis thereof to remotely press the tubular portion 72 of the escutcheon 16 into engagement with the sprinkler assembly 20 (FIGS. 6 and 7). The force F1 may be sufficient to press the tubular portion 72 into engagement with the cup 78 such that the one or more protuberances 86 are engaged with the one or more ribs 84. The force F1 may be applied until the end face 58 of the base 28 contacts the downward-facing surface 80 of the cup 78, thereby placing the escutcheon 16 in an installed position (FIG. 7) such that the rim portion 70 of the escutcheon 16 is in contact with the interior-facing surface 88 of the ceiling 24 or disposed proximate thereto.
Once the escutcheon 16 is pressed into engagement with the sprinkler assembly 20, a downward force F2 may be applied to the extension member 14 along the longitudinal axis to withdraw the body portion 12 from the escutcheon 16 (FIG. 8). The escutcheon 16 remains in the installed position (FIGS. 7 and 8), as the installation tool 10 moves downward in response to the downward force F2.
The description of the present disclosure is merely exemplary in nature and, thus, variations that do not depart from the gist of the disclosure are intended to be within the scope of the disclosure. Such variations are not to be regarded as a departure from the spirit and scope of the disclosure.
