Embodiments herein provide a modular gutter for use by bicycles and other conveyances. When utilized, a conveyance may be guided along the gutter either by an individual on the conveyance or adjacent to it, whether up or down the gutter. The gutter may be manufactured in various lengths and arrangements, and additionally, the components of the gutter are designed to permit multiple subunits/segments to be coupled to form longer gutters. Alternatively, the gutters may be cut to a desired length should the manufactured length be too long. Thus, the gutter may be sized for any of a variety of staircases. The gutter may be removably installed on existing staircases without the need to redesign or reconstruct the staircase.
A bicycle is described herein as an example embodiment, although a modular gutter may be used for other conveyances as well. For the purposes of describing embodiments herein, the term “conveyance” refers broadly to wheeled vehicles and other such devices, whether motorized or non-motorized, whether for carrying one or more individuals or not, such as unicycles, bicycles, tricycles, quads, skateboards, strollers, carts, etc.
FIG. 1A illustrates a modular gutter 100 in accordance with embodiments herein. Gutter 100 includes two rail segments 102 and 104 coupled together. Rail segments 102, 104 are shown with a concave or u-shaped upper surface configured to permit smooth movement of bicycle tires 103 of bike 105 along the surface. In addition, there are upper and lower endcaps 106, both of which are coupled to rail segments 102, 104. Endcaps 106 may be the same or each may be configured differently to accommodate different types or arrangements of stairs. For example, an endcap may be configured with a steeper or shallower approach angle as desired. In embodiments, endcaps 106 should provide a relatively smooth transition between stairs 110 and rail segments 102, 104. Also, in embodiments, the concave or u-shaped surface of rail segments 102, 104 may be centered or off-center along the rail segments and may be symmetrical or asymmetrical in curvature and/or wall height. An asymmetrical wall height may permit a user to lean their bicycle toward the lower wall, and still maintain sufficient wall height on both sides of the bicycle while avoiding rubbing the wheel/tire of the bike against the lower wall of the gutter.
Gutter 100 is configured with four support feet 112, although any suitable number of such feet may be used. In FIG. 1A, support feet 112 contact the run surfaces 114 of stairs 110. While in FIG. 1A there are support feet 112 for each stair, in embodiments there may not be a support foot 112 for each stair. Support feet 112 are shown with rounded lower surfaces, which provide a more universal fit to various stairs regardless of the incline angle of the staircase. In embodiments, other shapes and configurations of support feet 112 may be provided, such as having squared or angled edges.
Gutter 100 is identified as “modular” because the configuration of the elements permits 1, 2, 3, or more rail segments to be coupled together, as well as any desired or needed number of support feet to be used.
In use, a user 115 may walk up or down stairs 110 while pushing or guiding bicycle 105 along gutter 100.
FIG. 1B illustrates a partial perspective view of the modular gutter 100 of FIG. 1 in accordance with various embodiments. FIG. 1B shows rail segments 102 and 104 as well as two support feet 112. In addition, in FIG. 1B, multiple positioning supports 116 are provided. As shown, positioning supports 116 are ribbed/contoured to provide one or more points of contact with an edge of a stair. These points of contact provide a location of increased friction or resistance to secure/stabilize gutter 100 on stairs 110. In addition, positioning supports 116 provide a spacing element between support feet 112 or between a support foot 112 and an endcap 106. Spacing elements may be configured as positioning supports, or, in embodiments, spacing elements may be constructed with the primary function of spacing, with or without a positioning or other function. While one positioning support 116 is shown between support feet 112, the spacing may be adjusted by using positioning supports of different sizes and/or using more than one positioning support.
FIG. 1B also illustrates a channel 118 within rail segments 102, 104 into which support feet 112 and positioning supports 116 are inserted. In this embodiment, such elements may be slid into and along channel 118 to arrive at the desired orientation of the elements. In embodiments, the configuration (cross-sectional shape) of channel 118 corresponds to a portion of the elements inserted therein to facilitate a tight or secure fit.
FIG. 1B also illustrates an example mechanism for coupling various components together, such as endcaps 106 and rail segments 102, 104. Connecting rod 120 is shown inserted into a recess 122, which together form a post and pit style end joint. As illustrated, connecting rod 120 and recess 122 exhibit a semicircular cross-sectional shape, which prevent rotation of connecting rod 120 once inserted into recess 122. In other embodiments, other cross-sectional shapes may be utilized, such as square, round, triangular, or any other desired or suitable shape.
While in FIG. 1B a separate connecting rod is illustrated, it should be appreciated by one of skill in the art that integrated connecting rods may be used on any of the various elements described herein. For example, a rail segment may be configured with a male-type rod extending therefrom, which is configured to mate with a female recess on another component (endcap, another rail segment, etc.). In embodiments, other connecting elements, such as slidable rails, tabs, threaded couplings, etc. may be used instead of a connecting rod. In embodiments, connecting elements/means may be present at the terminal or adjoining ends of various components, although other arrangements may also be configured.
In embodiments, one or more elements may be formed from a rubber or other non-slip material. For example, the coupling of two elements formed from rubber, or coated with rubber or including a rubber seal or gasket, may inhibit separation of the elements except for as a result of the application of a sufficiently large force. In addition or alternatively, the joining of elements, such as introducing support feet 112 into channel 118 or coupling rail segment 102 to rail segment 104 as shown in FIG. 1B, may be reinforced using industrial adhesives, nails, screws, bolts, etc.
In other embodiments, there may be an internal locking fit between the components (support feet 112, positioning supports 116) and channel 118 to prevent the rail from sliding once in place. In one embodiment, locking pins (bolts, etc.) may be inserted from the sides of the rails through corresponding holes in the interior components (support feet 112, positioning supports 116) to position the components in a desired location/configuration.
FIG. 1C illustrates a partial exploded view of gutter 100. The manner in which the various components may be coupled together can be seen in this illustration. For example, the alignment and corresponding shape of the top rail of support foot 112 with channel 118 can be seen.
FIG. 1D provides an expanded view of a support foot 112 in accordance with embodiments. Support foot 112 has a rounded, lower contact surface 124 and an integrated top rail 126 designed to correspond to the shape of channel 118. The particular shape prevents support foot 112 from rotating within channel 118 and limits movement of support foot 112 to movement along the primary, longitudinal axis of channel 118.
Similar to support foot 112, FIG. 1E shows positioning support 116 with an integrated top rail 128 designed to correspond to the shape of channel 118 and control movement as discussed above. Additionally, positioning support 116 has a lower friction surface 130 designed to contact a stair edge and aid in securing gutter 100 in position on stairs 110.
FIGS. 1F and 1G illustrate rear and front views of an endcap 106 in accordance with embodiments herein. Endcap 106 provides a ramp that may be constructed with a variety of slopes and configurations as desired. In a particular embodiment, such as represented in FIG. 1A, endcap 106 provides a fairly shallow approach angle based on its location at the lower portion of stairs 110. Endcap 106 is shown with ramp 132 to effect this approach angle. In embodiments, endcap 106 may be configured with other approach angles. Additionally, endcap 106 shows recesses 122 that permit the coupling via connecting rods 120 to rail segment 102. Endcap 106 is also shown with an integrated rail 134 designed to correspond to the shape of channel 118 to further secure endcap 106 to rail segment 102.
FIG. 2A illustrates an alternative embodiment of a modular gutter 200. Gutter 200 has a rail segment 202, support feet 212, a connecting rod 220, and recesses 222. Such features are the same or substantially similar to those presented in FIGS. 1A-1G. However, FIG. 2A illustrates an alternative positioning support 216 (see also FIG. 2B). Positioning support 216 has an integrated top rail 228 designed to correspond to the shape of channel 218. Positioning support 216 has a claw-style base having two flanges 230 each configured to contact a stair edge. As shown, positioning support 216 has a ribbed/contoured interior 238 configured to further secure positioning support 216 on a stair edge. The angle made between the two flanges of the claw-style base is provided for illustrative purposes, and the angle may be adjusted as desired. In an embodiment, the base may be provided with an integrated adjustment mechanism, such as a flexible joint that permits the flanges of the base to flex/splay in response to the application of force.
FIG. 3 illustrates an alternative embodiment of a modular gutter 300. Gutter 300 is shown with rail segments 302 and 304, support feet 312, and positioning supports 316. These features provide the same or similar functionality to those described above. In FIG. 3, connecting rod 320 is configured to fit inside a large recess 322 that defines the interior of rail segment 302 or rail segment 304. In addition, rail segments 302 and 304 are provided with an integrated lower rail track 318. Support feet 312 and positioning supports 316 are configured with claw-style upper portions that are configured to fit around and to slide along integrated rail track 318. Similar to the embodiments of FIGS. 1A-1G and FIGS. 2A-2B, support feet 312, positioning supports 316, and rail track 318 are designed to have corresponding shapes to permit slidable engagement with controlled movement so that the components may be at least partially secured in place when the components are coupled together. Endcap 306 illustrates an alternate embodiment that provides a steeper approach angle and a flexible ramp 336 that may permit adjustment of the ramp angle to fit to a variety of configurations and inclines of stairs.
In embodiments, one or more elements may be formed out of recycled crumb rubber or another weather-resistant material offering a balance between flexibility and rigidity sufficient to prevent parts from cracking under stress or becoming too slippery when wet. Gutters may also be formed from one or more other materials such as steel, concrete, plastic, etc.
During installation, gutters may be placed onto or constructed on a staircase. Adhesives, nails, bolts, screws, or other such securing mechanisms may be used to secure the gutter to the staircase, although such features may be omitted. Gutters in accordance with embodiments herein can be removable, impermanent, and retrofittable, and can be configured to fit to any size staircase due to the modular aspects of the design.
In embodiments, a gutter may be contoured, such as having a u-shaped upper surface (the primary contact surface for the conveyance), or, alternatively a gutter may have a flat surface whether or not it is bound by raised edges/sides or not.
In an embodiment, a system may be constructed with more than one gutter, whether separate or coupled together side-by-side or manufactured as a single unit.
Although certain embodiments have been illustrated and described herein, it will be appreciated by those of ordinary skill in the art that a wide variety of alternate and/or equivalent embodiments or implementations calculated to achieve the same purposes may be substituted for the embodiments shown and described without departing from the scope. Those with skill in the art will readily appreciate that embodiments may be implemented in a very wide variety of ways. This application is intended to cover any adaptations or variations of the embodiments discussed herein. Therefore, it is manifestly intended that embodiments be limited only by the claims and the equivalents thereof.
