SIDEWALK ARCHITECTURAL FEATURES

FIELD

The present subject matter relates generally to sidewalk architectural features.

BACKGROUND

Sidewalks can be found in most cities to permit access to neighboring buildings and for purpose of allowing foot traffic. Sidewalks are generally disposed adjacent to roads and often include structures to assist in vehicle operation. These structures can include, e.g., street light posts, light posts, signage, and the like. Sidewalks may also include utility features such as fire hydrants, underground access and ventilation, outdoor seating areas, and the like. Moreover, vehicles from the adjacent road often traverse sidewalks, e.g., when entering a parking structure like a garage. Thus, sidewalks might further include sloped gradients interfacing with the neighboring road. Additionally, overhangs and awnings, building design, sidewalk dimensioning, green space, and the like can impact the layout of the sidewalk.

Sidewalk space is increasingly becoming an area of interest for commercial use. Traditionally, sidewalk space has been left unoccupied (e.g., open) unless actively being used by scaffolding when neighboring buildings were erected or worked on. Traditional structures like scaffolding and sidewalk sheds are typically used to protect people and objects on the sidewalk from falling debris while optionally permitting higher worker access, e.g., to the neighboring building. However, increasingly, sidewalk space represents an opportunity for business interactions such as branding and advertising. Accordingly, improvements to structures to be used/implemented on sidewalks are desired.

DETAILED DESCRIPTION

Reference now will be made in detail to embodiments of the present invention, one or more examples of which are illustrated in the drawings. The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any implementation described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other implementations. Moreover, each example is provided by way of explanation, rather than limitation of, the technology. In fact, it will be apparent to those skilled in the art that modifications and variations can be made in the present technology without departing from the scope or spirit of the claimed technology. For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that the present disclosure covers such modifications and variations as come within the scope of the appended claims and their equivalents.

As used herein, the terms “first”, “second”, and “third” may be used interchangeably to distinguish one component from another and are not intended to signify location or importance of the individual components. The singular forms “a,” “an,” and “the” include plural references unless the context clearly dictates otherwise. The terms “coupled,” “fixed,” “attached to,” and the like refer to both direct coupling, fixing, or attaching, as well as indirect coupling, fixing, or attaching through one or more intermediate components or features, unless otherwise specified herein. As used herein, the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having” or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, article, or apparatus that comprises a list of features is not necessarily limited only to those features but may include other features not expressly listed or inherent to such process, method, article, or apparatus. Further, unless expressly stated to the contrary, “or” refers to an inclusive- or and not to an exclusive- or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).

Approximating language, as used herein throughout the specification and claims, is applied to modify any quantitative representation that could permissibly vary without resulting in a change in the basic function to which it is related. Accordingly, a value modified by a term or terms, such as “about,” “generally,” “approximately,” and “substantially,” are not to be limited to the precise value specified. In at least some instances, the approximating language may correspond to the precision of an instrument for measuring the value, or the precision of the methods or machines for constructing or manufacturing the components or systems. For example, the approximating language may refer to being within a ±10 percent margin. When used in the context of an angle or direction, such terms include within ten degrees greater or less than the stated angle or direction. For example, “generally vertical” includes directions within ten degrees of vertical in any direction, e.g., clockwise or counter-clockwise.

Benefits, other advantages, and solutions to problems are described below with regard to specific embodiments. However, the benefits, advantages, solutions to problems, and any feature(s) that may cause any benefit, advantage, or solution to occur or become more pronounced are not to be construed as a critical, required, or essential feature of any or all the claims.

In general, sidewalk architectural features in accordance with embodiments described herein may be used at, or along, sidewalks to protect pedestrians against weather, falling debris, and the like. The sidewalk architectural features provide spatial flexibility without compromising physical strength. As such, sidewalk architectural features described herein can be used in previously unworkable areas or satisfy previously unmet spatial requirements. For example, a sidewalk architectural feature described herein may permit a pass-through span of at least sixteen feet between adjacent vertical members without exceeding a prescribed loading threshold of any one or more of the vertical members along the underlying ground. Sidewalk architectural features described in accordance with embodiments herein may further permit easy assembly and efficient transportation to and from the site of installation. The sidewalk architectural features may include one or more removable sleeves which engage with vertical members of the sidewalk architectural feature for providing removable attachment points between the vertical members and other support beams. The removable sleeves may permit easier onsite assembly through custom placement along the vertical members. The removable sleeves may also increase packing density of vertical members during transport to the site of installation.

In accordance with one or more embodiments described herein, sidewalk architectural features may not include platforms or raised surfaces suitable for pedestrian travel as typically seen in scaffolding. Instead, primary traffic of pedestrians and other sidewalk faring objects (e.g., bicycles, scooters, hand trolleys, automated vehicles, and the like) can occur along the underlying ground surface through one or more bays of the sidewalk architectural feature.

At least one of the bays can define a passthrough (passageway) in a length direction generally parallel with the sidewalk and a passthrough (passageway) in the width direction. Pedestrians and other traffic can generally pass through the bays without obstruction when using the passthroughs. In certain instances, at least one of the bays may define an elongated passthrough at least in the length direction to permit relatively wide objects (e.g., vehicles) to transverse the sidewalk through the bay. By way of non-limiting example, transverse passage may be particularly useful at locations where the adjacent building includes a feature, such as a garage entrance with two-way traffic, that makes obstruction in the transverse direction less desirable.

The sidewalk architectural feature may include electrical integration to permit use of heaters, lighting, fans, electronic displays, and other electrical devices on or within the sidewalk architectural feature. By way of non-limiting example, lighting may be included underneath a framework (roofing) structure to illuminate the underlying ground surface. In another exemplary embodiment, fans and displays may be suspended from the framework. Displays can include, for example, digital displays, analog displays, paper and/or fabric displays, billboards, and the like. Marketing signage and indicia can be coupled to the sidewalk architectural feature.

Inclusion of features like those described above can increase the effective surface area and weight of the sidewalk architectural feature. Additionally, these features (e.g., elongated passthroughs) may result in transmission of increased torque loading through the sidewalk architectural feature. Moreover, the sidewalk architectural feature (e.g., at interfaces between the vertical members and framework) may incur greater loading forces from high winds, seismic activity, impact by pedestrians, and the like. Thus, to afford desirable attributes of the sidewalk architectural feature like elongated spans without exceeding loading thresholds on the underlying ground surface, it is necessary to utilize a strengthened design. Traditional means of solving strength problems include the use of reinforcing elements or increasing the dimensions of the beams and members used in construction. However, these methods of strengthening the sidewalk architectural feature would also increase weight of the structure which might violate local regulations protecting against heavy objects being positioned on the sidewalk. Accordingly, sidewalk architectural features described herein provide advantageous opportunities to protect pedestrians and other traffic on sidewalks while simultaneously providing an aesthetically appealing, easy to assembly and transport, regulation forward design.

Referring now to the figures, FIG. 1 illustrates a perspective view of a portion of a sidewalk architectural feature 100 in accordance with an exemplary embodiment. The sidewalk architectural feature 100 may be positioned, for example, at, or adjacent to, a sidewalk. The sidewalk architectural feature 100 may extend along a length L of the sidewalk between an innermost portion and an outermost portion of the sidewalk in the width W direction. In certain instances, an innermost side of the sidewalk architectural feature 100 may be disposed proximate to a building or structure offset from an adjacent road. The outermost side of the sidewalk architectural feature 100, i.e., the portion of the sidewalk architectural feature 100 furthest from the building or structure, can be disposed above the sidewalk, above the adjacent road, above an intermediary section formed between the sidewalk and road (e.g., one or more plant beds and/or grassy areas), and the like.

In general, the sidewalk architectural feature 100 may include vertical members 102 extending vertically from the underlying ground surface (as described above, this may include the sidewalk, adjacent road structure, intermediary sections, and/or combinations thereof). In an embodiment, one of the vertical members 102 can extend vertically from a first type of underlying ground surface (e.g., the sidewalk) and another of the vertical members 102 can extend vertically from a second type of underlying ground surface (e.g., adjacent road). That is, in some instances the vertical members 102 can be simultaneously used on a plurality of different underlying surface types.

In an embodiment, the vertical members 102 can all share a common shape, a common size, or both a common shape and a common size. The vertical members 102 may be formed from a relatively rigid material. Exemplary materials include metals, alloys, rigid composites, high-strength natural fibers and woods, or combinations thereof. As described in greater detail below, the vertical members 102 can be configured to accommodate variable spatial requirements at the installation site. That is, the vertical members 102 can be configured to accommodate unique installation requirements specific to different installation locations. For example, the vertical members 102 can have adjustable heights in a height H direction, adjustable angular orientations relative to the height H direction, and the like. Moreover, attachment points (e.g., sleeves described in greater detail below) with the vertical members 102 may be variably positioned to permit an installation technician the ability to adjust beam connection locations during installation in response to unique spatial limitations at the installation site.

As described in greater detail with reference to FIGS. 8-10 and 16, at least one of the vertical members 102 can include a vertical adjustable element 148 configured to adjust a vertical height of the at least one vertical member 102. The vertical adjustment element 148 can be selectively adjusted to accommodate different underlying ground surface heights and features. For instance, the vertical member 102 may be lengthened in the height H direction using the vertical adjustment element 148 where there are low spots in the underlying ground surface. Conversely, the vertical member 102 can be shortened using the vertical adjustment element 148 where the underlying ground surface at the foot of the vertical member 102 rises. The relative height of the vertical members 102 may be set prior to installation and/or during installation.

In certain instances, at least one of the vertical members 102 can be canted relative to an absolute vertical orientation. That is, the height of at least one of the vertical members 102 can be angularly offset from an absolutely vertical orientation in the height H direction in the installed state. By way of example, the angular offset can be in a range of approximately 0.1° and 30°. In other instances, at least one of the vertical members 102 can extend vertically from the underlying ground surface. In a particular embodiment, all of the vertical members 102 can extend vertically from the underlying ground surface.

Referring again to FIG. 1, a framework 104 may be disposed above the underlying ground surface and can be supported at least in part by at least some, such as all, of the vertical members 102. In an embodiment, the entirety of the framework 104 may be at least 3 feet above ground level in the height H direction, such as at least 4 feet above ground level, such as at least 5 feet above ground level, such as at least 6 feet above ground level, such as at least 7 feet above ground level, such as at least 8 feet above ground level, such as at least 9 feet above ground level, such as at least 10 feet above ground level, such as at least 12 feet above ground level, such as at least 14 feet above ground level, such as at least 16 feet above ground level. The framework 104 can include a structure configured to form a cover, e.g., a roof, of the sidewalk architectural feature 100. The framework 104 may be disposed at a relative elevation with respect to the underlying ground surface so as to allow pedestrians, vehicles, construction equipment, or the like generally unencumbered movement within passageways of the sidewalk architectural feature 100. In certain instances, the framework 104 may be disposed at, or adjacent to, an uppermost end of the vertical members 102. For example, the framework 104 may be coupled to at least one of the vertical members 102 at an uppermost end of the vertical member 102.

In an embodiment, the framework 104 can define a single best fit plane. In another embodiment, the framework 104 can define a plurality of best fit planes. For instance, as described below, the sidewalk architectural feature 100 can define a plurality of different bays 106. Each bay 106 can include a framework 104 having its own best fit plane. The best fit plane(s) of at least one of the frameworks 104 may be disposed at an angular orientation approximately coplanar with the length L and width W directions. That is, at least one of the framework(s) 104 may be generally horizontal. Meanwhile, the underlying ground surface can be either horizontal or angularly offset from horizontal. In another embodiment, at least one of the best fit planes of the framework 104 may be angularly offset from the length L and/or width W directions regardless of the angle of the underlying ground surface. It should be understood that the framework 104 can be angularly coplanar with the underlying ground surface or angularly offset therefrom. Angled frameworks 104 may be particularly useful at sidewalk junctions or at entrances to adjacent buildings where an increased elevation of the framework 104 is desired.

The sidewalk architectural feature 100 may define one or more bays 106. Each bay 106 can define a generally open volume within the sidewalk architectural feature 100. By way of non-limiting example, the generally open volume can permit passage (e.g., of a person, trolley, handcart, vehicle and the like) through the sidewalk architectural feature 100 in the width W direction and/or the length L direction. In certain instances, at least one of the bays 106 can be defined by a volume inscribed by a bounding perimeter formed by intersecting surfaces joined together at the vertical members 102 and framework 104. For instance, the portion of the sidewalk architectural feature 100 depicted in FIG. 1 can generally define a single bay, bounded by first, second, third, and fourth vertical members 102A, 102B, 102C, and 102D and framework 104. The bay 106 depicted in FIG. 1 is represented by a dashed box.

FIG. 2 illustrates a top view of the sidewalk architectural feature 100 in accordance with an exemplary embodiment. The bay 106 of the sidewalk architectural feature 100 illustrated in FIG. 1 is represented by dashed lines 108. As depicted in FIG. 2, bays 106 can be disposed at either/both sides of the bay 108 in the length L direction. In this regard, the length of the sidewalk architectural feature 100 can have any desirable length by adding and subtracting bays 106. Alternatively, or in addition to adding and subtracting bays 106, the relative sizes of the bays 106 can be modified to adjust span distances. That is, relative size(s) of the bays 106 can be modified, as described hereinafter, to accommodate unique sidewalk structures, shapes, and length requirements.

The framework 104 can include a plurality of members coupled together to provide support to the structure. By way of example, the members can include a first plurality of members 112 extending in the width W direction and a second plurality of members 114 extending in the length L direction. In certain embodiments, the first and second plurality of members 112 and 114 can be generally orthogonal with one another. In other embodiments, the first and second plurality of members 112 and 114 can include non-orthogonal members angularly offset from one another by non-right-angled offsets. The first and second plurality of members 112 and 114 can be connected together at one or more interfaces to form a gridwork. Additional supports 116 can be used to increase angular strength and further mitigate flexure of the sidewalk architectural feature 100, particularly during loading events such as encountered on windy days. These additional supports 116 can include, for example, angularly offset linear members, arcuate members (such as shown in FIG. 2), complex shaped members, and the like.

Referring again to FIG. 1, the bays 106 of the sidewalk architectural feature 100 can be joined together through one or more interfaces 110. The interfaces 110 can be configured to selectively receive fasteners, e.g., threaded or nonthreaded fasteners, clips, and the like, to selectively secure adjacent bays 106 together. In the illustrated embodiment, each vertical member 102 has one interface 110 for engagement with the adjoining bay 106. In other embodiments, at least one of the vertical members 102 can have a plurality of interfaces 110, such as two interfaces 110, three interfaces 110, etc. In yet other embodiments, at least one of the vertical members 102 can be free of any interfaces 110. For instance, the middle vertical member 102 (disposed between the first and second vertical members 102A and 102B) may omit an interface 110 to provide suitable flexure of the sidewalk architectural feature 100. It should be understood that the interface 110 can be omitted or modified at any other one or more of the vertical members 102 based on spatial and operational requirements.

The interfaces 110 can include junctions through which the adjacent bays 106, and more particularly adjacent vertical members 102 of the adjacent bays 106 can be joined together. By way of non-limiting example, the interfaces 110 can include plates projecting from the vertical members 102 in the length L direction. Alternatively, the interfaces 110 can project at least partially in the width W direction and/or height H direction. In an embodiment, the interfaces 110 may be removable from the vertical members 102. In certain instances, removable interfaces 110 can permit higher packing density of the vertical members 102 during transportation of the sidewalk architectural feature 100 to the installation site. That is, by packing and transporting the vertical members 102 without the interfaces 110 preinstalled, it may be possible to increase packing density and more efficiently transport the components of the sidewalk architectural feature 100 to the installation site. In an embodiment, the interfaces 110 can be repositionable along the height of the vertical members 102 to accommodate, e.g., unique installation site geometries. During assembly, the installers can position the interfaces 110 at variable heights, angles, or both to accommodate unique geometries.

FIG. 3 illustrates an exemplary view of the sidewalk architectural feature 100 as seen from a front view, e.g., from the adjacent road. The aforementioned interfaces 110 between adjacent bays 106 are depicted in the engaged state whereby the adjacent bays 106 are coupled together.

In an embodiment, a gap 118 can exist between adjacent bays 106. The gap 118 can correspond with the section of the sidewalk architectural feature 100 including the interface 110. The gap 118 can be formed, for example, between vertical members 102 of adjacent bays 106. In certain instances, gaps 118 between adjacent bays 106 can all share the same relative dimensions in the length L direction. In other instances, at least two gaps 118 of the sidewalk architectural feature 100 can have different relative dimensions in the length L direction.

In certain instances, each bay 106 can be spaced apart from the adjacent bay 106 by a gap 118. In such a manner, the sidewalk architectural feature 100 can include sets (e.g., a first set S₁and a second set S₂) of vertical members 102 disposed adjacent to one another in the length L direction.

In an embodiment, at least one of the bays 106 can include a plurality of angled support members 120 extending between the vertical members 102 and the framework 104. The angled support members 120 can increase structural integrity of the at least one bay 106. The angled support members 120 can protect the sidewalk architectural feature 100 from collapsing under high-strain loading conditions, particularly (but not necessarily exclusively) in the length L direction. As depicted, in certain instances the angled support members 120 may be coupled to the interfaces 110. In an embodiment, the angled support members 120 can be directly coupled to the interfaces 110. In another embodiment, the angled support members 120 can be indirectly coupled to the interfaces 110, e.g., through a sleeve described in greater detail below. Coupling the angled support members 120 to the interface 110 may provide rotational resistance during loading conditions by anchoring adjacent vertical members 102 together. Moreover, use of adjacent angled support members 120 may effectively mitigate rotational loading forces at the interfaces 110, preventing transfer of torque to the vertical members 102.

FIGS. 19 through 21 illustrate an exemplary embodiment of the angled support member 120. The depicted angled support member 120 includes a body 192 defining a reinforcement feature 194 disposed along an upper edge of the body 192. The reinforcement feature 194 depicted in FIGS. 19 through 21 includes a single bent edge. In other embodiments, the reinforcement feature 194 can include another suitable reinforcement shape configured to provide enhanced strength characteristics to the body 192. The angled support member 120 extends between an upper end 196 and a lower end 198. The upper end 196 can be coupled to the framework 104 and the lower end 198 can be coupled to the vertical member 102 or a sleeve coupled therewith and described in greater detail below.

As depicted in FIG. 3, the bay 108 defines a first dimension, D₁, as measured in the length L direction, different from a second dimension, D₂, as measured in the length L direction, of the adjacent bays 106. By way of non-limiting example, the first dimension can be at least 14 feet, such as at least 15 feet, such as at least 16 feet, such as at least 17 feet, such as at least 18 feet, such as at least 19 feet. In an embodiment, the first dimension can be approximately 20 feet. In yet another embodiment, the first dimension may be no greater than 30 feet, such as no greater than 25 feet, such as no greater than 22.5 feet. By way of non-limiting example, the second dimension can be at least 1 foot, such as at least 5 feet, such as at least 10 feet, such as at least 12 feet. In an embodiment, the second dimension can be less than 14 feet. In a particular instance, a ratio of the first dimension to the second dimension [D₁:D₂] can be at least 1.1:1, such as at least 1.2:1, such as at least 1.3:1, such as at least 1.4:1, such as at least 1.5:1, such as at least 1.6:1, such as at least 1.7:1, such as at least 1.75:1.

In an embodiment, the bay 108 may correspond with an elongated bay configured for wide passthrough in the width W direction. For example, certain sidewalk locations may be disposed between the adjacent road and one or more garage entrances. These sidewalk locations may require unobstructed access to the garage entrance(s) sufficient to accommodate passage of at least one vehicle therethrough. At such locations, use of bays 106 having small dimensions in the length L direction may not be suitable. Additionally, use of angled support members 120 may restrict passage through the sidewalk architectural feature 100 in the width W direction. Accordingly, the elongated bay 108 may be used to accommodate these passthrough requirements. Similarly, building entrances and display windows may warrant use of elongated passthroughs to increase physical and/or visual access to the building. In an embodiment, at least 25% of the first dimension, D₁, of the bay 108 can be unobstructed for passthrough in the width W direction along the entire height of the bay 108, such as at least 30%, such as at least 40%, such as at least 50%, such as at least 60%, such as at least 70%, such as at least 75%, such as at least 80%, such as at least 85%, such as at least 90%, such as at least 95%, such as at least 99%. In a particular embodiment, substantially all of the first dimension, D₁, of the bay 108 can be unobstructed for passthrough in the width W direction.

FIG. 4 illustrates a side elevation view of the sidewalk architectural feature 100 in accordance with an embodiment. More particularly, a single bay 106 is shown from the side view. As depicted, the bay 106 can include a plurality of angled support members 120 extending between vertical members 102 and the framework 104. In an embodiment, the angled support members 120 can extend in the length L, width W, and height H directions. With respect to the width W direction, as depicted in FIG. 4, at least one of the angled support members 120 can define an angular offset, a, as measured with respect to a vertical axis in the height H direction, in a range of 1° and 89°, such as in a range of 30° and 60°. In a particular embodiment, the angular offset, a, can be approximately 45°. In a particular embodiment, the angular offset, a, can be approximately the same in the width W and length L directions. In another embodiment, the angular offset, a, can be different in the width W and length L directions.

In certain instances, force transmitted through at least some of the angled support members 120 can cancel each other out. For instance, first and second angled support members 120A and 120B can generally transmit the same, or similar, loading forces as compared to one another, between the framework 104 and shared vertical member 102. These loading forces, F₁and F₂, can be transmitted through the first and second angled support members 120A and 120B, respectively, and interact at a shared vertical member 102 (the middle depicted vertical member 102). Lateral components of the forces F₁and F₂may cancel, or generally cancel, each other out, resulting in transmission of only, or substantially only, vertical force in the height H direction to the shared vertical member 102.

Sidewalk architectural features 100 in accordance with one or more embodiments described herein can be configured to accommodate high loading forces, such as those encountered during high wind events, seismic activity, and the like without buckling or failing. By way of example, loading forces F_L, as depicted in FIG. 3, may bias the sidewalk architectural feature 100 in the length L direction. Particularly at elongated spans, such as at bay 108 where there are no angled support members 120, these loading forces F_Lmay stress the sidewalk architectural feature 100, causing wear and fatigue which may lead to premature failure. To compensate for these loading forces F_Land prevent premature failure, the sidewalk architectural feature 100 may include one or more flexible interfaces. These flexible interfaces can be formed, for example, between vertical members 102 and the framework 104, between different portions of the framework 104, and/or between different portions of the vertical members 102.

FIG. 5 depicts a flexible interface 122 in accordance with an exemplary embodiment. In particular, FIG. 5 illustrates an enlarged view of a portion of the sidewalk architectural feature 100 as shown in Box A of FIG. 3. It should be understood that the exemplary embodiment depicted in FIG. 5 may be modified and components thereof can be rearranged while employing the principles of operation described herein for accommodating loading forces F_Lshown in FIG. 3.

FIG. 5 depicts vertical members 102 of adjacent bays 106 (FIG. 3) coupled to the framework 104 through interfaces 124 described in greater detail hereinafter. As shown in FIG. 5, the interfaces 124 can be coupled to the vertical members 102 using a plurality of fasteners 126. By way of example, the fasteners 126 can include threaded fasteners, non-threaded fasteners, clips, pins, and the like. The fasteners 126 may be configured to mitigate relative movement between each of the vertical members 102 and a respective interface 124. Alternatively, the fasteners 126 may be replaced with welds, adhesives, and the like. In an embodiment, the interfaces 124 may be coupled to the framework 104 through a plurality of fasteners 128. The fasteners 128 may be the same or different as compared to fasteners 126. In a particular embodiment, the fasteners 128 include at least one of threaded fasteners, non-threaded fasteners, clips, pins, and the like.

The framework 104 may be coupled to the vertical members 102 through the flexible interface 122. In such a manner, the framework 104 can flex relative to the vertical members 102. The flexible interface 122 depicted in FIG. 5 includes a single connection axis 130 extending in the width W direction (into the page). That is, the framework 104, or a portion of the framework 104 extending between opposite ends of the bay 108 in the length L direction, and underlying structure to which the framework 104 can be coupled together through a single axis 130 at either end of the bay 106. Referring to FIG. 6, which depicts a cross-sectional view as seen along Line B-B in FIG. 5, the axis 130 may extend in the width W direction and include a plurality of connection points 132. The axis 130 may be disposed between the vertical members 102 and at least a portion 134 of the framework 104. The portion 134 of the framework 104 (which in certain instances can include the entire framework 104) can flex relative to the vertical members 102 in rotational directions indicated by dashed arrows T (FIG. 5). That is, for example, the portion 134 of the framework 104 can rotate relative to the vertical members 102 about the axis 130. In such a manner, loading forces F_Lon the portion 134 of the framework 104 can be transmitted to the vertical members 102 without undesirably torqueing the vertical members 102. In particular, the immediately adjacent vertical members 102 (i.e., those vertical members 102 closest to the flexible interface 122) may experience reduced torque loading conditions when the portion 134 is acted upon by the loading force F_L.

In an embodiment, a plurality of connection points (e.g., fasteners 132) can be disposed along the length of the axis 130. In another embodiment, the axis 130 can include a continuous connection interface formed along the length, or portions of the length, of the axis 130. For instance, the continuous connection interface can include a hinged interface whereby a hinge extends along at least a portion of the axis 130. In yet other embodiments, the axis 130 can include a single connection point, e.g., a single fastener 132.

Referring still to FIG. 6, in accordance with certain embodiments, the framework 104 may include an upper portion 134 and a lower portion 136. The lower portion 136 can be disposed on a first side of the flexible interface 122 and the upper portion 134 can be disposed on a second side of the flexible interface 122. That is, for example, the lower portion 136 can be fixedly (e.g., rigidly) coupled to the vertical members 102 while the upper portion 134 can be flexibly coupled to the vertical members 102 through the flexible interface 122. In the illustrated embodiment, each vertical member 102 is coupled to the upper portion 134 of the framework 104 through a respective flexible interface 122. The flexible interfaces 122 can have the same or different relative geometries, fastening types, strengths, and the like as compared to one another. In such a manner, flexure of the sidewalk architectural feature 100 can be adapted to accommodate various needs, e.g., in view of spatial and loading requirements at a particular installation site.

In an embodiment, the upper and lower portions 134 and 136 can have different constructions as compared to one another. For instance, referring again to FIG. 1, the upper portion 134 can include both the first and second plurality of support members 112 and 114 (FIG. 2). The lower portion 136 can have a different construction as compared to the upper portion 134. For instance, as depicted in FIG. 1, the lower portion 136 can include only one of the first plurality of support members 112 at each end of the bay 106 in the length L direction and none of the second plurality of support members 114. Yet other arrangements and configurations are possible within the scope of the disclosure.

Referring still to FIG. 1, the sidewalk architectural feature 100 can further include a rail 178. The rail 178 can be coupled with the framework 104 and/or vertical members 102. In a particular embodiment, the rail 178 is coupled to at least one of the upper and lower portions 134 and 136 of the framework 104. Referring to FIG. 6, the rail 178 can be coupled to both the upper and lower portions 134 and 136. In an embodiment, the rail 178 can be configured to provide torsional resistance at the interface 122, providing resistance against flexure of the sidewalk architectural feature 100 during occurrence of loading forces F_L.

As depicted in FIG. 6, the angled support members 120 can be coupled to the framework 104 through the lower portion 136. More particularly, the angled support members 120 can be coupled to the lower portion 136 of the framework 104 at one or more interfaces 138. The angled support members 120 can be coupled to the framework 104 through the interfaces 138 using, e.g., fasteners, clips, pins, and the like.

FIG. 7 illustrates an enlarged view of the flexible interface 122 as seen in Box C of FIG. 6. In the particular embodiment illustrated in FIG. 7, the axis 130 is formed between a flange of an I-beam of the upper portion 134 of the framework 104 and an upper flange 140 of the lower portion 136 of the framework 104. In other non-illustrated embodiments, the flexible interface 122 can be formed between different portions or members of the upper and lower portions 134 and 136 of the framework 104 or other parts of the sidewalk architectural feature 100. For instance, the flexible interface 122 can be formed between the interfaces 124 and the framework 104, between the interfaces 124 and the vertical members 102, or within any one or more of the interfaces 124 and vertical members 102.

In an embodiment, the flexible interface 122 is configured to permit flexure of the sidewalk architectural feature 100 in a single axis, e.g., along the length L direction. In another embodiment, the flexible interface 122 can be configured to permit flexure of the sidewalk architectural feature 100 in two or more axis. For example, the flexible interface 122 can permit the upper portion 134 of the framework 104 to flex in the length L direction and the height H direction. Directional flexibility can be controlled, for example, by selecting an appropriate axis 130 orientation. For example, orienting the axis 130 parallel with the width W direction can mitigate flexure in the width W direction. Conversely, orienting the axis 130 offset from two of the length L, width W, and height H directions can permit flexure in two axis. Yet further, orienting the axis 130 offset from all three of the length L, width W, and height H directions can permit flexure in all three axis.

In both of the embodiments described above (i.e., single-axis flexure and multi-axis flexure), flexure of the sidewalk architectural feature 100 can generally be prohibited in one or more axis, e.g., in the width W direction. Limiting flexure in one or more axis may be particularly important where the sidewalk architectural feature 100 is constrained by spatial limitations of the installation site. For instance, where the sidewalk architectural feature 100 is being installed in a tight fit with a neighboring building (e.g., abutting the building or immediately adjacent thereto), flexure in the width direction (toward and away from the building) may be undesirable. Similarly, when accommodating traffic light posts, light posts, power line posts, trees, and the like it may be desirable to limit flexure to prevent the sidewalk architectural feature 100 from contacting (e.g., rubbing or impacting) said feature.

Engineered flexure of the sidewalk architecture feature 100 as described above may reduce fatigue by spreading loading forces F_Lover a greater number of components. That is, for example, by permitting the framework 104, or a portion thereof, to flex (particularly over elongated spans), the loading force F_Lcan be better distributed along the vertical members 102 and even between the neighboring bays 106. Inflexible interfaced spans (particularly for elongated spans) undergoing loading forces F_Lmay cause excessive loading conditions at one or more of the vertical members 102. These excessive loading conditions can wear the interfaces or components of the sidewalk architecture feature 100 at a faster rate, leading to more costly maintenance and/or higher cost materials. Additionally, many cities have point loading threshold requirements that cannot be exceeded. These point loading threshold requirements often define a maximum amount of force that can be imparted on the underlying ground surface by a structure. This can be defined, for example, by maximum average loading thresholds per area or individual contact maximums. That is, by way of example, certain locations may require point loading thresholds of no greater than 2000 pounds per square foot (PSI) of any part of a structure contacting the underlying ground surface, such as no greater than 1900 PSF, such as no greater than 1700 PSF, such as no greater than 1500 PSF, such as no greater than 1300 PSF, such as no greater than 1200 PSF, such as no greater than 1100 PSF, such as no greater than 1000 PSF, such as no greater than 900 PSF, such as no greater than 800 PSF, such as no greater than 700 PSF, such as no greater than 600 PSF, such as no greater than 500 PSF, such as no greater than 400 PSF, such as no greater than 300 PSF, such as no greater than 250 PSF, such as no greater than 225 PSF. Under normal operating conditions, non-flexible interfaced structures may satisfy such point loading threshold. However, when loading forces F_Lare introduced, these inflexible structures may cause individual ground contact areas to exceed the point loading threshold. Conversely, sidewalk architectural features 100 in accordance with embodiments described herein may remain under the point loading thresholds at all ground contact points (e.g., at the vertical members 102) as a result of their flexibly interfaced construction.

FIG. 8 illustrates a perspective view of a vertical member 102 in accordance with an exemplary embodiment of the present disclosure. The vertical member 102 generally includes an elongated member 142 configured to extend in the height H direction when in use. The elongated member 142 can be hollow along at least a portion thereof, such as along the entire length of the elongated member 142. The elongated member 142 can extend between an uppermost end 144 and a lowermost end 146. The vertical adjustment element 148 can be coupled to the elongated member 142, e.g., at the lowermost end 146. In a particular embodiment, the vertical adjustment element 148, or a portion thereof, can be disposed within the elongated member 142. An additional view of the vertical adjustment element 148 is shown in FIG. 16. The vertical adjustment element 148 can be selectively deployed at a plurality of vertical positions with respect to the elongated member 142 so as to effectively change a height of the uppermost end 144 of the elongated member 142 when in use. In certain instances, the vertical adjustment element 148 is infinitely adjustable within a predefined range of adjustment. That is, the vertical adjustment element 148 can be selectively disposed at any relative position between an uppermost position and a lowermost position with respect to the elongated member 142. In this regard, the installing technician can set the effective length of the vertical member 102 without relying on preset stop positions. In other instances, the vertical adjustment element 148 can be adjustable using a plurality of preset stop positions. For example, referring to FIG. 9, the elongated member 142 can define a plurality of stop positions, e.g., holes 150, which can receive a through-connector (e.g., a pin, a tine, a fastener, or the like) that can engage with the vertical adjustment element 148 to pin the elongated member 142 and vertical adjustment element 148 together. The holes 150 can be spaced apart in the height H direction. The holes 150 can be spaced apart by equal or varying distances. In certain instances, a lowermost hole 150A can be spaced apart from an uppermost hole 150B by at least 6 inches, such as by at least 12 inches, such as by at least 18 inches, such as by at least 24 inches, such as by at least 30 inches. In an embodiment, the holes 150 can extend along at least 1% of the height of the elongated member 142, such as along at least 5%, such as along at least 10%, such as along at least 25%, such as along at least 50%. In a more particular embodiment, the holes 150 can extend along at least 75% of the elongated member 142, such as along at least 90%, such as along at least 95%, such as along at least 99%. The relative height of the holes 150 with respect to the elongated member 142 may be determined largely in view of the height of the elongated member 142. Shorter elongated members 142 may require a greater distance of variable displacement relative to the vertical adjustment element 148 whereas longer elongated members 142 may require shorter distance of variable displacement.

By selecting a particular hole 150 to receive the through-connector, the installation technician can set the effective height of each vertical member 102 in view of underlying ground structure and geometry. This may be performed on site, in advance, or in combination (e.g., initially set in advance and fine-tuned on site). The maximum range of adjustability, AMAX, can be defined in view of the holes 150 (FIG. 16).

Referring again to FIG. 8, the vertical adjustment element 148 can include a foot 152 configured to contact the underlying ground surface. The foot 152 can include, for instance, a platform configured to distribute loading forces to the underlying ground surface. In certain embodiments, the foot 152 can include one or more fasteners or receiving areas 154 configured to receive a fastening element configured to couple the foot 152 to the underlying ground surface or an intermediary member (e.g., a wooden support block, a concrete pier, a rubber dampener, and the like).

In an embodiment, the vertical member 102 can be further configured to receive a sleeve 156 having an interface 158 (FIGS. 10 through 12) for coupling elements, e.g., angled support members 120, rails, advertising, signage, displays, and the like, to the vertical member 102. The sleeve 156 can be removable from the elongated member 142. In this regard, the elongated members 142 can be transported to the installation site without unnecessary structures which might reduce packing density and increase transportation costs.

The sleeve 156 can generally include an annular body 160 defining an inner surface having a cross-sectional shape configured to seat along the elongated member 142. In certain instances, the annular body 160 can include a split body design such as illustrated in FIGS. 12 and 13. Split body design can allow the installation technician to quickly attach the sleeve 156 to the elongated member 142 without having to slide the sleeve 156 over one of the ends 144 or 146 which may already include an enlarged attachment. Moreover, the split body design can permit the installation tech to install the sleeve 156 with the vertical member 102 already coupled to the framework 104. In this regard, the order of operations for assembling the sidewalk architectural feature 100 can be performed with greater variability. That is, the sleeve 156 does not need to be installed before connecting the vertical member 102 to the framework 104.

The split body can be connected together to form the sleeve 156 through one or more interfaces 162. The interfaces 162 can include aligned receiving areas 164 which can be configured to receive a connecting element 166 (FIG. 11) that can selectively couple the interfaces 162 together. FIG. 11 is a cross-sectional view of the sleeve 156 as seen along Line C-C in FIG. 9. FIG. 11 illustrates a view of the split body design with two portions coupled together at the interfaces 162 by connecting elements 166. Further depicted is an optional inner sleeve 168 that can be disposed between the sleeve 156 and the elongated member 142. The inner sleeve 168 may include a material configured to enhance an interaction between the sleeve 156 and the elongated member 142. For instance, by way of non-limiting example, the inner sleeve 168 may increase frictional resistance between the sleeve 156 and the elongated member 142 so as to mitigate slipping therebetween. Alternatively, the inner sleeve 168 may decrease frictional resistance to permit the installation technician to more easily assembly and position the inner sleeve 168 along the elongated member 142. The inner sleeve 168 may prevent corrosion or pitting of the sleeve 156 and/or elongated member 142 or serve another similar purpose. The inner sleeve 168 may be split bodied or include a non-split annular body.

FIGS. 14 and 15 illustrate an exemplary view of the interface 124 described above with respect to FIG. 5. The interface 124 can be coupled at, or adjacent to, the uppermost end 144 of the elongated member 142. The interface 124 can generally include a connection portion 170 configured to be engaged with the elongated member 142 and a connection portion 172 configured to be engaged with the framework 104. The embodiment illustrated in FIG. 14 includes two connection portions 172A and 172B configured to be engaged with the framework 104. The embodiment illustrated in FIG. 15 includes a single connection portion 172 configured to be engaged with the framework 104. In certain instances, the embodiments illustrated in FIGS. 14 and 15 may be used simultaneously at different portions of the sidewalk architectural feature 100. For instance, the embodiment depicted in FIG. 14 may be used where the first and second plurality of members 112 and 114 (FIG. 2) are joined together while the embodiment depicted in FIG. 15 may be used where intersecting (orthogonal) members are not present. The connection portion 170 depicted in FIGS. 14 and 15 includes a receiving area 174 defining a bore into which the uppermost end 144 of the elongated member 142 can be received. Connecting elements (not shown) can be installed within receiving areas 176 to selectively couple the vertical members 102 to the interface 124.

FIGS. 17 and 18 depict a double-flanged beam 180 in accordance with an embodiment. The beam 180 includes an elongated member 182 extending between opposite longitudinal ends 184 and 186. Flanges 188 and 190 can extend from one or more central components 192. At least one of the flanges 188 and 190 can include a reinforcement feature, such as a geometrically bent end 192. The reinforcement feature can increase strength to weight of the bam 180, permitting higher resistance to loading forces F_Land decreasing the overall weight of the sidewalk architectural feature 100.

As used herein, the term “sidewalk architectural feature” refers to a system (e.g., an assembly) that can be disposed on an underlying ground surface including a sidewalk. In certain instances, the sidewalk architectural feature can be used on other types of underlying ground surfaces.
