The invention relates to pipe sleeves, and more particularly to pipe sleeves used on floating docks.
Floating docks are used to moor boats and other water craft, and are advantageous for use where the water level may change because the dock surface will always stay above the water level. Typically the floating dock includes a number of floats coupled to the underside of the dock.
The dock is commonly anchored to the bottom of the waterway using a plurality of posts or pipes that are driven into or otherwise secured to the lake bottom or river bed (e.g., via augers on the bottom of the pipes). The pipes are commonly coupled to the dock using pipe sleeves that form a free-floating fit with the pipe. This enables the dock to rise and fall with the changing water level.
The present invention provides an improved pipe sleeve arrangement suitable for use on floating docks. Unlike prior art one-piece pipe sleeves that require burdensome manipulation of the long pipes and their auger attachments during installation and removal of the dock, the two-piece construction of the present pipe sleeve allows easier movement and storage of the dock because the pipes can be taken off and secured to the dock very easily. Furthermore, the two-piece pipe sleeve of the present invention does not include any welds, making the manufacture of the pipe sleeve less expensive. In addition, the pipe sleeve of the invention has a low-profile design, and much of the mounting hardware is hidden from view when assembled.
More specifically, the present invention provides a pipe sleeve assembly having a base plate and a sleeve portion. The base plate includes a base portion defining a longitudinal axis and configured for receiving a pipe. The base plate further includes a first flange extending from the base portion in a first direction generally normal to the longitudinal axis and lying in a first plane. The first flange includes an aperture for receiving a first fastener configured to secure the base plate to a mounting surface. The base plate also includes a second flange extending from the base portion in the first direction, spaced from the first flange in a second direction generally parallel to the longitudinal axis, and lying in a second plane spaced from the first plane. The sleeve portion includes a body portion configured for receiving the pipe, and a third flange extending from the body portion in the first direction. The third flange overlies at least a portion of the second flange and includes an aperture. A fastener stud extends from the second flange and is received in the aperture in the third flange to secure the sleeve portion to the base plate.
In one aspect of the invention, the fastener stud is part of a second fastener extending through an aperture in the second flange. The second fastener includes a head having a head height, and the first and second planes are spaced apart by a distance substantially equal to the head height of the second fastener.
In another aspect of the invention, the third flange also overlies at least a portion of the first flange and at least a portion of the first fastener. The first fastener includes a head having a head height, and the third flange is spaced from the first flange by a distance substantially equal to the head height of the first fastener.
The invention also provides a floating dock assembly including a frame, at least one float coupled to the frame, a sleeve assembly coupled to a mounting surface of the frame, and a support member slidably received in the sleeve assembly such that the support member can move relative to the sleeve assembly. The sleeve assembly includes a base plate having a base portion defining a longitudinal axis and receiving the support member. The base plate further includes a first flange extending from the base portion in a first direction generally normal to the longitudinal axis and abutting the mounting surface. The first flange includes an aperture for receiving a first fastener securing the base plate to the mounting surface. The base plate also includes a second flange extending from the base portion in the first direction, spaced from the first flange in a second direction generally parallel to the longitudinal axis, and spaced from the mounting surface. The sleeve assembly further includes a removable sleeve portion having a body portion receiving the support member, and a third flange extending from the body portion in the first direction. The third flange overlies at least a portion of the second flange. A second fastener is coupled with the second and third flanges to secure the sleeve portion to the base plate.
Other features and advantages of the invention will become apparent to those skilled in the art upon review of the following detailed description, claims, and drawings.
Before one embodiment of the invention is explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or being carried out in various ways. Also, it is understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of “including”, “having” and “comprising” and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items.
As seen in
The pipe sleeve assemblies 38 retain the pipes 46 while providing a free-floating fit that enables the pipe sleeve assemblies 38, and therefore the entire dock section 18, to move vertically relative to the pipes 46 to accommodate variations in the water level. It should be understood that the illustrated pipes 46 and auger portions 50 represent only one way of anchoring a floating dock, and that the pipe sleeve assemblies 38 could be used to slidably retain other support members that may be secured to the river bed or lake bottom in different manners.
The base plate 54 further includes one or more mounting flanges 74 that extend from the base portion 62. In the illustrated embodiment, there are four mounting flanges 74. Two of the mounting flanges 74 extend from the base portion 62 in a first direction D1 generally normal to the longitudinal axis 70, and two of the mounting flanges 74 extend from the base portion 62 in a second direction D2 generally normal to the longitudinal axis 70 and substantially opposite to the first direction D1.
As best illustrated in
The base plate 54 further includes one or more assembly flanges 90 that extend from the base portion 62. In the illustrated embodiment, there are two assembly flanges 90. One of the assembly flanges 90 extends from the base portion 62 in the first direction D1 and is intermediate the two mounting flanges 74 extending in the first direction D1. The other assembly flange 90 extends from the base portion 62 in the second direction D2 and is intermediate the two mounting flanges 74 extending in the second direction D2. In other words, in the illustrated embodiment each assembly flange 90 is spaced in a direction generally parallel to the longitudinal axis 70 from the corresponding two mounting flanges 74 on the same side of the base portion 62.
As best illustrated in
As illustrated in
The illustrated base plate 54 is formed from a single stamped piece of steel, aluminum, or other suitable material. The thickness of the base plate 54 is substantially uniform at all locations on the base plate 54, including the flanges 74, 90, and the base portion 62. No welding is required to create the base plate 54. Spaced transition portions 106 extend between the base portion 62 and the respective flanges 74, 90 and define contact areas for contacting the sleeve portion 58. As illustrated in
The sleeve portion 58 includes a body portion 110 configured for receiving the pipe 46. As illustrated, the body portion 110 includes a plurality of ribs 112 that strengthen the body portion 110. The specific configuration and number of ribs 112 can vary as desired.
The sleeve portion 58 further includes one or more sleeve flanges 114 that extend from the body portion 110. In the illustrated embodiment, there are two sleeve flanges 114. One of the sleeve flanges 114 extends from the body portion 110 in the first direction D1 and the other sleeve flange 114 extends from the body portion 110 in the second direction D2. The sleeve flanges 114 overlie respective assembly flanges 90 and each sleeve flange 114 includes an aperture 118 for receiving the respective stud portion 102 of the assembly fasteners 98. Locking nuts 122 or other suitable mechanisms are fastened on the stud portions 102 to secure the sleeve portion 58 to the base plate 54.
The sleeve portion 58 includes transition portions 126 between the body portion 110 and each sleeve flange 114. The transition portions 126 contact the respective transition portions 106 of the base plate 54 when the sleeve portion 58 is assembled to the base plate 54. The illustrated transition portions 126 extend substantially the entire length of the body portion 110. As best illustrated in
In the illustrated embodiment, the sleeve flanges 114 are sized to also overlie at least a portion of the mounting flanges 74 on the corresponding side of the pipe sleeve assembly 38. When assembled, each sleeve flange 114 is spaced from the respective mounting flanges 74 by a distance D3 that is substantially equal to or just slightly larger than a head height Hm (see
The illustrated sleeve portion 58 is also formed from a single stamped piece of steel, aluminum, or other suitable material. The thickness of the sleeve portion 58 is substantially uniform at all locations on the sleeve portion 58 with the possible exception of the ribs 112. No welding is required to create the sleeve portion 58. When the sleeve portion 58 is assembled to the base plate 54, the overall distance the pipe sleeve assembly 38 extends from the mounting surface 42 is less than about 2.5 inches, and as illustrated is about 2.43 inches. This relatively small overall dimension also contributes to the generally low-profile design of the pipe sleeve assembly 38.
While the illustrated pipe sleeve assembly 38 has an overall height in the direction of the longitudinal axis 70 of about five inches, the height can vary as desired. For example, the pipe sleeve assembly 38 could be extended to include another set of oppositely-extending assembly flanges 90 and/or another set of oppositely-extending mounting flanges 74 arranged in a manner similar to the illustrated assembly flanges 90 or mounting flanges 74. The sleeve flanges 114 could also be lengthened as desired to accommodate the additional assembly flanges 90 and/or mounting flanges 74. Changing the overall height of the pipe sleeve assembly 38 will vary the ability of the pipe 46 to move within the pipe sleeve assembly 38. Increasing the height of the pipe sleeve assembly will constrain the relative movement to a more vertical direction (as illustrated in
The design of the pipe sleeve assembly 38 facilitates assembly, installation, and removal of the floating dock 10. First, the base plate 54 is positioned on the mounting surface 42 with the assembly fasteners 98 extending through the apertures 94 in the assembly flanges 90. The mounting fasteners 82 are then secured as described above to secure the base plate 54 to the frame 22. Once the base plate 54 is secured to the mounting surface 42, the heads 104 of the assembly fasteners 98 are constrained between the mounting surface 42 and the assembly flanges 90 so that the fasteners 98 cannot fall out of the base plate 54.
The installer, can then position the pipe 46 (with the auger portion 50 already attached to the pipe 46) against the base portion 62 and couple the sleeve portion 58 to the base plate 54 as described above. To remove the pipe 46 from the pipe sleeve assembly 38, the installer needs only remove the sleeve portion 58 from the base plate 54. No cumbersome vertical-direction manipulation of the pipe 46 is required. Additionally, the auger portion 50 need not be repeatedly removed from and installed on the pipe 46.
