MODULAR RAMP WITH HANDRAILS AND LOCKING ASSEMBLY

BACKGROUND

Ramp and platforms can provide an inclined surface on which a user can travel between a lower elevation and an upper elevation, for example, for access to an entrance of a building. Ramps and platforms are becoming increasingly common, due in part to the passage of the Americans with Disabilities Act (ADA), which requires public buildings to be designed or modified to provide wheelchair access. These ramps and platforms assist those people confined to wheelchairs or who use walkers by providing a suitable pathway or ramp way to the entrances of public and private buildings, which may be at elevations above or below ground level.

DETAILED DESCRIPTION

Ramp and platform assemblies can provide an inclined access to buildings, cars, and other structures. This inclined access can assist people with accessing certain structures by providing a suitable pathway or rampway to an entrance. Ramp and platform assemblies can be particularly helpful for those who are not able to traverse stairs or a steep slope to get to an entrance. While ramp and platform assemblies can be helpful, there can be many challenges to designing a suitable ramp assembly. As one example, ramp and platform assemblies often need to be customizable, as the specific requirements and demands for a particular building site can vary greatly (e.g., due to the terrain, elevation changes, entrance location, etc., that is specific to each site). Thus, a ramp or platform assembly that is suitable for a first structure may not be suitable for separate, second structure. As another example, ramp and platform assemblies can be required to meet specific regulations (e.g., due to the Americans with Disability Act), which can further complicate the overall design of a ramp and platform assembly and can render any on-site assembly of the ramp and platform assembly challenging. Accordingly, there exists a need for ramp and platform assemblies that are modular in construction, designed to meet specific regulations, and designed to minimize the cost and assembly time of on-site installation.

The present disclosure addresses these and other issues with respect to ramp and platform assemblies. As described in further detail herein, embodiments of the present disclosure are generally directed to modular ramp and platform assemblies which can be configured to provide ramping and horizontal deck surfaces for access to a structure or other destination. These ramp and platform assemblies can include a decking for providing a pathway to a desired entrance or area of a structure. These ramp and platform assemblies can also include one or more handrail assemblies for assisting those using the ramp and platform assemblies. In some examples, the handrail assemblies can be adjustable between two (or more) angular positions, including, for example, a first angular position where the handrail assembly is collapsed for handling purposes, and a second angular position, where the handrail assembly extends outwards from the decking surface and is accessible for use. By transitioning between two (or more) angular positions, the ramp assembly can provide a more compact profile for handling, storage, and shipping (e.g., when the handrail assembly is in the first angular position) while also providing for easy installation and use (e.g., by transitioning the handrail assembly from the first angular position to the second angular position). These and other advantages of the present disclosure will be described in more detail herein.

FIG. 1A illustrates a ramp assembly 100 in accordance with one or more exemplary embodiments of the present disclosure. The ramp assembly 100 can be designed and configured to provide a suitable pathway for which a user or object can travel across. As shown in FIG. 1A, the ramp assembly 100 can include a tread assembly 102 and one or more handrail assemblies 104. The tread assembly 102 can provide a surface upon which a user or object can travel over. The handrail assemblies 104 can couple to the tread assembly 102 and can provide support and assistance to those who are using the ramp assembly 100. While the illustrated embodiment is described as a ramp assembly 100, it should be appreciated that the features described herein can also apply to a platform assembly.

Still referring to FIG. 1A, the tread assembly 102 can include a decking surface 106 and one or more curbs 108. The decking surface 106 can be formed from one or more decking components 110 which together can provide a surface for walking, transporting, or otherwise moving between a first end 112 and a second end 114 of the tread assembly 102. The curbs 108 can provide an area for the decking components 110 of the decking surface 106 to couple to. As shown in FIG. 1A, when the decking components 110 are coupled to the curbs 108, the decking components 110 extend between the two curbs 108 to define the width of the tread assembly 102. In some examples, the width of the tread assembly 102 can be defined as the distance between a first side 116 and a second side 118 (see FIG. 6E).

While the illustrated embodiment shows the curbs 108 forming a part of the tread assembly 102, it should be appreciated that the curbs 108 can form a part of a separate assembly, such as the handrail assembly 104, or may be separate from the tread assembly 102 and handrail assembly 104. In some examples, the decking surface 106 and curbs 108 can be formed from a single, integrated component. These and other arrangements of the decking surface 106 and curbs 108 are within the scope of the present disclosure.

As shown in FIG. 1A, the handrail assembly 104 can include one or more post members 122 and one or more rail members 124. The post members 122 can be any suitable structural member for supporting and framing the handrail assembly 104. The rail members 124 can be any suitable railing structure for users of the ramp assembly 100 to hold or grab for support while using the ramp assembly 100. As illustrated in FIG. 1A, the rail members 124 can couple to the post members 122 to extend at least between the post members 122, and, in some instances, extend beyond the post members 122 along the length of the tread assembly 102.

While the illustrated embodiment shows the ramp assembly 100 as including a tread assembly 102 and a handrail assembly 104, it should be appreciated that the ramp assembly 100 can include additional components or assemblies for providing a suitable pathway for which a user or object can travel across. As one non-limiting example, the ramp assembly 100 can include supporting posts, which can raise or lower the first or second ends 112, 114 of the tread assembly 102. As another non-limiting example, the ramp assembly 100 can include a series of ramp assemblies 100 that are coupled together. These and other arrangements of the ramp assembly 100 are within the scope of the present disclosure.

FIGS. 1B and 1C illustrate different views of the handrail assembly 104 coupled to the ramp assembly 100. Referring to FIGS. 1A-IC together, the handrail assembly 104 can couple to the tread assembly 102 through a bracket member 126. As will be described in more detail herein, the bracket member 126 can be a structural member that is configured to movably couple the handrail assembly 104 to the tread assembly 102 so that the handrail assembly 104 can transition between one or more positions. In the illustrated embodiment, four bracket members 126 couple to two curbs 108 of the tread assembly 102, with each bracket member 126 also coupling to a post member 122 of a handrail assembly 104. A fastener 127 can be used to couple each post member 122 to a bracket member 126 to thereby couple each handrail assembly 104 to the tread assembly 102.

When coupled to the bracket member 126, each handrail assembly 104 can be configured to transition between at least two angular positions: a first angular position where the handrail assembly 104 is stowed for case of handling (as shown in FIG. 2A), and a second angular position where the handrail assembly 104 is upright relative to the tread assembly 102 for use (as shown in FIG. 2D). FIGS. 2A-2D illustrate the handrail assemblies 104 transitioning from the first angular position to the second angular position. When the handrail assemblies 104 are in the first angular position, each handrail assembly 104 can be nested with the decking surface 106 of the tread assembly 102, as shown in FIG. 2A. In some examples, when in the first angular position, one of the handrail assemblies 104 can rest upon the decking surface 106 while another one of the handrail assemblies 104 can rest upon the other handrail assembly 104. In some examples, each handrail assembly 104 is pivoted at least 90 degrees from an upright position (e.g., from the second angular position) when the handrail assemblies 104 are in the first angular position. In various examples, the handrail assembly 104 can be in the stowed position (e.g., the handrail assembly 104 is more compact for storage and handling) when the handrail assembly 104 is in the first angular position.

In various examples, the handrail assemblies 104 can be locked in position so that the handrail assemblies 104 remain in the first angular position until released. For instance, the ramp assembly 100 can include a fastening mechanism (e.g., a latch, strap, etc.) that can be used to hold the handrail assembly 104 in the first angular position. In some cases, when the handrail assembly 104 is in the first angular position, the fastener 127 can be tightened, which can thereby fix the handrail assembly 104 in position. Additionally, or alternatively, a locking assembly (e.g., such as the locking assembly 358 as shown in FIGS. 9A and 9B) can be used to secure the handrail assemblies 104 in the first angular position.

FIGS. 2B and 2C illustrate a handrail assembly 104 transitioning from the first angular position to the second angular position. When the handrail assemblies 104 transition from the first angular position to the second angular position, each handrail assembly can be pivoted away from the decking surface 106 to an upright position relative to the decking surface 106 (e.g., the post member 122 can be substantially normal to the decking surface 106). As shown in FIG. 2B, one of the handrail assemblies 104 may be pivoted towards an upright position while the other handrail assembly 104 remains fixed in place in the first angular position. In some examples, when this first handrail assembly 104 reaches the second angular position (as shown in FIG. 2C), the remaining handrail assembly 104 may be pivoted towards an upright position.

FIG. 2D illustrates the handrail assemblies 104 in the second angular position. When the handrail assemblies 104 are in the second angular position, the handrail assemblies 104 can be accessible to a user for grasping or holding while the user uses the ramp assembly 100. As shown in FIG. 2D, each handrail assembly 104 is in an upright position relative to the decking surface 106 (e.g., a longitudinal axis of a post member 122 can be substantially normal to the decking surface 106). In some examples, the handrail assemblies 104 pivot at least 90 degrees when pivoting between the first and second angular positions.

In various examples, the ramp assembly 100 can include a fastening mechanism (e.g., a latch, strap, etc.) that can be used to hold the handrail assemblies 104 in the second position. In some cases, when the handrail assembly 104 is in the second position, the fastener 127 can be tightened, which can thereby fix the handrail assembly 104 in position. In some embodiments, a fastener 129 (as shown in FIG. 1B) can be configured to hold the handrail assembly 104 in the second angular position. For example, the fastener 129 can be a pin that is configured to couple to both the bracket 126 and the post member 122 of the handrail assembly to thereby hold the handrail assembly 104 in the second angular position. Additionally, or alternatively, a plate member 134 can be configured to the hold the handrail assembly 104 in the second angular position. For instance, as will be described in more detail herein, the plate member 134 can be coupled to the post member 122 and can be configured to form an interference fit with the bracket 126 to thereby hold the handrail assembly 104 in the second angular position. In some examples, the handrail assembly 104 can be in the operational position (e.g., the handrail assembly 104 is accessible for use) when the handrail assembly 104 is in the second angular position.

Although the illustrated embodiment shows the handrail assemblies 104 transitioning from the first angular position to the second angular positions, it should be appreciated that the handrail assemblies 104 can transition to additional (or alternative) positions besides those illustrated herein. For example, in some embodiments, the handrail assembly 104 can pivot from the second angular position to the first angular position (e.g., the handrail assembly 104 can be folded towards the decking surface 106 from an upright position). Configuring the ramp assembly 100 so that the handrail assemblies 104 can transition between the first and second (or other) angular positions can greatly improve case of installation and handling of the ramp assembly 100. In some examples, the handrail assemblies 104 can transition between the first and second angular positions without needing any tooling. Accordingly, the ramp assembly 100 can be quickly adjusted between the first and second angular positions as desired.

Besides being repositioned angularly, in some embodiments the handrail assemblies 104 can be configured to be repositioned in other manners. For example, in some embodiments, the handrail assemblies 104 can be raised and lowered relative to the decking surface 106. Accordingly, in some examples, the handrail assembly 104 can be adjusted along an axis that is substantially normal to the decking surface 106. As will be described in more detail herein, in some embodiments, the handrail assemblies 104 can be adjusted between a first position (e.g., elevated position) and a second position (e.g., lowered position) relative to the decking surface 106. Adjusting the handrail assembly 104 to the first position can create a clearance between the handrail assemblies 104 and the tread assembly 102, which can thereby allow for the handrail assembly 104 to pivot relative to the decking surface 106. Adjusting the handrail assembly 104 to the second position can secure the handrail assembly 104 in place and thereby restrict the handrail assemblies 104 from pivoting undesirably. Thus, in some instances, adjusting the handrail assembly 104 relative to the decking surface 106 can help secure the handrail assembly 104 in position (e.g., in the second angular position). Furthermore, in some examples, the handrail assemblies 104 can be adjusted both angularly (e.g., between the first and second angular positions) and vertically relative to the decking surface 106 (e.g., between the first and second elevated and lowered positions).

Additional details of the handrail assembly 104 and the bracket assembly 126 will now be described. FIGS. 3A and 3B illustrate views of a handrail assembly 104. As shown in FIG. 3A, the handrail assembly 104 includes two post members 122 coupled to two rail members 124. Each post member 122 can be an elongated member extending between a first end portion 128 and a second end portion 130. In some examples, each post member 122 can include two or more portions that couple together to form the post member 122. In some embodiments, the handrail assembly 104 can form all, or a portion, of the curb 108. As shown in FIG. 3B, each post member 122 can include a first aperture 131 and a second aperture 132 formed at or near the first end portion 128. The first aperture 131 can be configured to receive the fastener 129 to thereby secure the handrail assembly 104 in the second angular position and, in some instances, in the second (e.g., lowered) position relative to the decking surface 106. The second aperture 132 can be configured to receive the fastener 127 to couple the post member 122 to the bracket member 126. The first and second apertures 131, 132 can be positioned along any desired location of the post member 122. For example, as shown in FIG. 3B, the second aperture 132 can be positioned off-centered of the longitudinal axis of the post member 122. In some cases, the second aperture 132 can define a pivot point 133 at or about the center of the second aperture 132, which can be the location about which the handrail assembly 104 pivots relative to the decking surface 106 (e.g., between the first and second angular positions).

As previously described, in some embodiments, a plate member 134 can be coupled to the post member 122 of the handrail assembly 104, with the plate member 134 being configured to form an interference fit with the bracket 126 to help secure the handrail assembly 104 in the second angular position (e.g., when the handrail assembly 104 is lowered into the second position relative to the decking surface 106). As shown in FIG. 1B, the plate member 134 can be coupled to a lower portion of the post member 122 so that at least a portion of the plate member 134 overlaps with the bracket member 126 when the handrail assembly 104 is in the second, lowered position. In some examples, the plate member 134 can be positioned on the post member 122 so that plate member 134 is substantially centered between the upper and lower ends of the bracket member 126 when the handrail assembly 104 is in the second, lowered position. These arrangements of the plate member 134 relative to the bracket member 126 can form an interference fit that prevents the handrail assembly 104 from pivoting while in the second, lowered position. For instance, when the handrail assembly 104 is in the second, lowered position, at least a portion of the plate member 134 can contact the bracket member 126 (as shown in FIG. 1C). This contact (and/or positioning) between the plate member 134 and the bracket member 126 can prevent the handrail assembly 104 from pivoting. Thus, in some examples, to pivot the handrail assembly 104 from the second angular position to the first angular position, the handrail assembly 104 may first need to be positioned in the first, raised position so that the handrail assembly 104 has sufficient clearance from the plate member 134 for pivoting.

In some arrangements, the handrail assembly 104 can form an interference fit with the curb 108 when the handrail assembly 104 is in the second, lowered position. For instance, while positioned in the second, lowered position, the handrail assembly 104 can be positioned adjacent to the curb 108 such that any attempt to pivot the handrail assembly 104 results in the handrail assembly 104 colliding with the curb 108 and thus preventing the handrail assembly 104 from pivoting between the first and second angular positions. Accordingly, in some examples, the handrail assembly 104 may need to be positioned at the first, elevated position so that the handrail assembly 104 can have an adequate amount of clearance to pivot around the ends of the curb 108.

FIGS. 4A and 4B illustrate views of the bracket member 126. As shown in FIG. 4A, the bracket member 126 can include a body having a first portion 142, a second portion 144 spaced apart from the first portion 142, and a third portion 146 coupling the first and second portions 142, 144 together. The first, second and third portions 142, 144, 146 can be configured to couple to both the tread assembly 102 and the handrail assembly 104. For example, the first, second and/or third portions 142, 144, 146 can be configured to form an interference fit with a curb 108 of the tread assembly 102. Additionally, or alternatively, the first, second and third portions 142, 144, 146 can be sized and spaced to define an opening (e.g., the space between the first, second, and third portions 142, 144, 146) that can receive a portion of the handrail assembly 104 within. Accordingly, in some examples, a post member 122 of the handrail assembly 104 can be disposed at least partially between the first, second and third portions 142, 144, 146 of the bracket member 126.

Referring to FIGS. 4A and 4B together, the first and/or second portions 142, 144 of each bracket member 126 can define a slot 136 that extends along an axis between a first end portion 138 and a second end portion 140. The slot 136 can be configured to receive the fastener 127 within to secure the post member 122 to the bracket member 126. In some embodiments, the post member 122 can be adjustable between the first and second end portions 138, 140 of the slot 136 (e.g., the post member 122 can be raised and lowered along the length of the slot 136). For example, with the fastener 127 received within both the aperture 132 and the slot 136, the post member 122 can slide along the length of the slot 136, which can thereby move the post member 122 relative to the decking surface 106 (e.g., by moving the post member 122 away from or towards the decking surface 106). In some of these examples, or otherwise, moving the post member 122 along the length of the slot 136 can also adjust the positioning of the pivot point 133. Thus, in some examples, the pivot point 133 can be adjustable along the length of the slot 136. In various embodiments, the post member 122 can be pivotable within the slot 136. For example, the fastener 127, second aperture 132, and slot 136 can be sized and configured to allow the post member 122 to pivot relative to the bracket member 126 (e.g., as previously shown with reference to FIGS. 2A-2D). In some examples, the bracket member 126 can also include an aperture 135, which can be configured to receive the fastener 129 to help secure the handrail assembly 104 in position.

While the illustrated embodiment shows the bracket member 126 as including the slot 136, it should be appreciated that, in some embodiments, the post member 122 may include a slot in addition to (or in lieu of) the slot 136 to allow for the handrail assembly 104 to be adjustable relative to the decking surface 106. Accordingly, in some embodiments, the bracket member 126 or the post member 122 may include features that allow for the post member 122 to be movably coupled to the bracket member 126. More specifically, in some embodiments, the post member 122 and/or bracket member 126 can include features which allow for the post member 122 to slide and pivot relative to the bracket member 126. As one non-limiting example, the post member 122 may form a hinge with the bracket member 126, which allows for the post member 122 to pivot relative to the bracket member 126. As another non-limiting example, the post member 126 and/or bracket member 126 can include one or more features (e.g., bearings, a groove, etc.) that allow for the post member 122 to slide relative to the bracket member 126. These and other arrangements of the post member 122 and bracket member 126 are within the scope of the present disclosure.

In some embodiments, the ramp assembly 100 can include a securing assembly 152 which can secure the handrail assembly 104 in an upright, or operational position. FIGS. 5A and 5B illustrate a ramp assembly 100 including a securing assembly 152. As shown in FIG. 5B, the securing assembly 152 can include an attachment member 154 and a securing member 156. The attachment member 154 can couple to the bracket member 126 and can be configured to define an opening with the bracket member 126 for receiving a portion of the handrail assembly 104 (e.g., the post member 122) within. In some examples, this opening is defined as the space between the attachment member 154 and the first, second, and third portions 142, 144, 146 of the bracket member 126. The attachment member 154 can be positioned between and spaced from the ends of the bracket member 126 so that the handrail assembly 104 can be lowered and raised into and out of the opening defined by the bracket member 126 and the attachment member 154. As will be described in further detail herein, lowering the handrail assembly 104 into this opening can restrict the handrail assembly 104 from pivoting while raising the handrail assembly 104 out of the opening can allow for the handrail assembly 104 to pivot as desired. The securing member 156 may be any suitable fastening mechanism, which can couple to the handrail assembly 104 to hold the handrail assembly 104 in its lowered position (e.g., when the post member 122 is positioned within the opening). For example, the securing member 156 may be a set screw that can be configured to press against the post member 122 within the opening and thereby hold the post member 122 in its position.

To secure the handrail assembly 104 in an operational position (e.g., in the second angular position), the handrail assembly 104 can be pivoted into the second angular position and lowered (or otherwise adjusted) into the opening formed by the bracket member 126 and the attachment member 154. In this position, the handrail assembly 104 may be restricted from pivoting into the first angular position unintentionally, as a portion of the handrail assembly 104 (e.g., the post member 122) will collide with either the tread assembly 102 (e.g., the curb 108), the attachment member 154, and/or the bracket member 126 when attempting to pivot from the second angular position to the first angular position. In some of these examples, or otherwise, the securing member 156 can further secure the handrail assembly 104 in the upright position by, for instance, coupling to a portion of the handrail assembly 104 (e.g., the post member 122) while the handrail assembly 104 is positioned adjacent the attachment member 154.

While the illustrated embodiment shows the handrail assembly 104 being secured in position with the securing assembly 152, it should be appreciated that, in some embodiments, other components or assemblies may be used to secure the handrail assembly 104 in position in addition to (or in lieu of) the securing assembly 154. As one non-limiting example, the fastener 129 may be used with the securing assembly 152 to help secure the handrail assembly 104 in position. Additionally, or alternatively, a locking assembly 358 (as shown in FIGS. 8A-9B), may be used to secure the handrail assembly 104 in position. These and other arrangements of the ramp assembly 100 are within the scope of the present disclosure.

FIGS. 6A-6E illustrate various end views of the ramp assembly 100 while the handrail assembly 104 transitions from a stowed position (as shown in FIG. 6A) to an operational position (as shown in FIG. 6E). As shown in FIG. 6A, the handrail assemblies 104 are positioned in the first angular position, with a first handrail assembly 104 nested with the decking surface 106 of the tread assembly 102 and a second handrail assembly 104 folded onto the first handrail assembly 104 such that the second handrail assembly 104 rests at least partially upon the stop member 134 of the first handrail assembly 104. In the illustrated embodiment, both handrail assemblies 104 are sized such that the second end portions of the post members 122 and the rail members 124 are positioned between the first and second sides 118, 120 of the tread assembly 102. Accordingly, in some examples, the height of the handrail assembly 104 (e.g., the length between the end of the post member 122 to an end of the rail member 124) can be substantially equal to or less than the width of the tread assembly 102.

The handrail assemblies 104 may be pivoted to different degrees relative to an upright position. For example, as shown in FIG. 6A, an axis L1 of the first handrail assembly 104 can be pivoted to an angle 148, which can be more than about 90 degrees relative to the upright position (e.g., 95 degrees, 100 degrees, 105 degrees, 110 degrees, 115 degrees, etc.), while an axis L2 of the second handrail assembly 104 can be pivoted to an angle 150, which can be about 90 degrees or less relative to the upright position (e.g., 90 degrees, 85 degrees, 80 degrees, 75 degrees, etc.). In one embodiment, both handrail assemblies 104 can be pivoted beyond 90 degrees relative to the upright position. In some embodiments, only one handrail assembly 104 is pivoted beyond 90 degrees. In various embodiments, neither handrail assembly 104 is pivoted beyond 90 degrees.

FIG. 6B shows a partial end view of the handrail assembly 104 in the first angular position. As shown in FIG. 6B, the pivot point 133 of the post member 122 is positioned at the first end portion 138 of the slot 136. Positioning the pivot point 133 of the post member 122 at the first end portion 138 of the slot 136 can create sufficient clearance between the post member 122 and the tread assembly 102 (or other portions of the ramp assembly 100, such as the securing assembly 152) so that the handrail assembly 104 can pivot freely without being restricted by the curb 108. In some examples, the pivot point 133 can spaced apart from the curb 108 along a direction substantially normal to the decking surface 106 (e.g., the pivot point 133 is raised above the ends of curb 108). Additionally, or alternatively, positioning the pivot point 133 at the first end portion 138 of the slot 136 can create sufficient clearance between the plate member 134 and the bracket member 126 to allow for the handrail assembly 104 to pivot without the plate member 134 colliding with the bracket member 136.

In some examples, the pivot point 133 can be adjusted between a first position, where the handrail assembly 104 is free to pivot as desired (e.g., between the first and second angular positions), and a second position, where the handrail assembly 104 is substantially restricted from pivoting (e.g., is secured in position). FIG. 6C illustrates the handrail assembly 104 with the pivot point 133 in the first position. As shown in FIG. 6C, the post member 122 can be positioned within the slot 136 so that the first end portion 128 of the post member 122 is vertically spaced apart from the end of curb 108 (or other portion of the tread assembly 102) along a direction that is substantially normal to the decking surface 106. When in the first position, the post member 122 may be able to pivot at least 90 degrees relative to the upright position (e.g., to the first position, as shown in FIGS. 6A and 6B). In some embodiments, the post member 122 can be configured to pivot relative to the decking surface 106 when the post member 122 is spaced apart from the decking surface 106.

FIGS. 6D and 6E illustrates the handrail assembly 104 with the pivot point 133 in the second position. As shown in FIG. 6D, the post member 122 is positioned within the slot 136 such that the pivot point 133 is at the second end portion 140 of the slot 136. Positioning the post member 122 in this manner can create a fit between the tread assembly 102 and the handrail assembly 104 that restricts any (or most) pivoting between the tread assembly 102 and the handrail assembly 104. In some of these examples, or otherwise, the pivot point 133 is positioned between the ends of the curb 108 along a direction substantially normal to the decking surface 106. Positioning the pivot point 133 in this manner can create an overlap between the handrail assembly 104 and the tread assembly 102 (e.g., there is no clearance between the two assemblies along a direction substantially normal to the decking surface 106), which can prevent or restrict the handrail assembly 104 from pivoting, as the post member 122 will collide with the curb 108 or other portion of the tread assembly 102 when attempting to pivot the handrail assembly 104. Additionally, in some examples, positioning the pivot point 133 in this manner can also create an interference fit between the plate member 134 and the bracket member 126 (e.g., a portion of the plate member 134 and bracket member 126 contact one another). Accordingly, positioning the post members 122 so that the post members 122 overlap with at least a portion of the tread assembly 102 (e.g., as shown in FIGS. 6D and 6E), can restrict the handrail assembly 104 from pivoting into the first angular position undesirably and thereby can allow for the handrail assemblies 104 to remain substantially normal to the decking surface 106 of the tread assembly 102 throughout use (e.g., the handrail assembly 104 can remain in the second angular position).

In some examples, the securing assembly 152 (as shown in FIGS. 5A and 5B) can also be used to secure the handrail assembly 104 in the operational position. As one non-limiting example, positioning the pivot point 133 at the second end portion 140 of the slot 136 can result in a portion of the handrail assembly 104 (e.g., the post member 122) being positioned within the opening defined by attachment member 154 and the bracket member 126. In this position, the post member 122 can collide with the attachment member 154 (or other portion of the ramp assembly 100, such as the bracket member 126) when attempting to pivot into the first angular position. Accordingly, in some examples, the attachment member 154 can restrict the handrail assembly 104 from pivoting from the second angular position to the first angular position. Furthermore, in some examples, the securing member 156 can be used to prevent or restrict the pivot point 133 from being adjusted unintentionally. For instance, when the pivot point 133 is positioned at the second end portion 140 of the slot 136, the securing member 156 can be coupled to a portion of the handrail assembly 104 (e.g., the post member 122), which can further limit any movement of the pivot point 133 and thereby hold the pivot point 133 in position. Additionally, as previously described, other components and assemblies, such as the fastener 129 and the locking assembly 358 (as shown in FIGS. 8A-9B), can be used to secure the pivot point 133 in position.

FIG. 7 is a flow diagram illustrating an example method 200 of forming a ramp assembly. The method 200 can be used with any of the ramp assemblies described herein, including the ramp assembly 100.

At step 201, the method 200 begins with positioning a ramp assembly (e.g., the ramp assembly 100) between a first surface and a second surface. In some embodiments, the ramp assembly can include a tread assembly (e.g., the tread assembly 102) and one or more handrail assemblies (e.g., the handrail assemblies 104). In some examples, the tread assembly can include a decking surface (e.g., the decking surface 106) that is coupled to one or more curbs (e.g., the curbs 108) which are disposed at either side (e.g., the first and second sides 118, 120) of the decking surface. The handrail assemblies can each include one or more post members (e.g., the post members 122) which are coupled to one or more rail members (e.g., the rail members 124). In some embodiments, the handrail assemblies can couple to the tread assembly through one or more bracket members (e.g., the bracket members 126). In some of these embodiments, or otherwise, the bracket members can pivotably couple the handrail assemblies to the tread assembly, which can allow for the handrail assemblies to transition between two or more angular positions relative to the tread assembly.

To position the ramp assembly between the first and second surfaces, the user can position a first end of the ramp assembly at the first surface and a second end of the ramp assembly at the second surface. In some examples, either the first or second surfaces can be a ground surface, a structural surface (e.g., an entry to a stairwell, an entrance to a building, a portion a vehicle etc.), a separate ramp assembly, or a combination thereof.

At step 202, the method 200 can optionally include pivoting the handrail assembly from a first angular position to a second angular position. In some embodiments, the ramp assembly can be stowed with one or more of the handrail assemblies in a first angular position (e.g., as shown in FIGS. 2A, 6A, etc.). Positioning the handrail assemblies in the first angular position can be beneficial for users who handle the ramp assembly, as the ramp assembly can be less cumbersome to maneuver. In order for the handrail assembly to be accessible for the user during use of the ramp assembly, each handrail must transition from the first angular position to at least an upright, or second angular position (e.g., as shown in FIGS. 2D, 6E, etc.). Accordingly, in some examples, the user can manually move the desired handrail assembly by pivoting the handrail assembly upwards to the second angular position. In some embodiments, the user can pivot each handrail assembly until the handrail assembly is substantially normal to the decking surface of the tread assembly. In some examples, the handrail assembly may be locked in the first angular position with a locking assembly (e.g., the locking assembly 358). Accordingly, in some of these examples, or otherwise, the handrail assembly may need to be unlocked from the locking assembly before being capable of pivoting to the second angular position.

In some embodiments, step 202 can be performed before step 201. For instance, a user may pivot the handrail assemblies into the second angular position prior to positioning the ramp assembly between a first and second surface.

At step 203, the method can optionally include adjusting the pivot point of the handrail assembly (e.g., the pivot point 133) from a first position to a second position. In some examples, after the handrail assembly has been rotated into an upright angular position relative to the decking surface, the pivot point of the handrail assembly can be adjusted relative to decking surface. In some cases, the pivot point can be moved between a first position, where the handrail assembly is free to pivot relative between the first and second angular positions, and a second position, where the handrail assembly is substantially restricted from pivoting between the first and second angular positions. In various examples, the pivot point can be lowered (e.g., by lowering the handrail assembly relative to the decking surface) or raised (e.g., by raise the handrail assembly relative to the decking surface). In some embodiments, positioning the pivot point at the second position can secure the handrail assembly in the second angular position and restrict the handrail assembly from pivoting to the first angular position. Additionally, or alternatively, a securing assembly (e.g., the securing assembly 152) may be utilized to secure the handrail assembly in the first and second positions. In other examples, a fastener (e.g., a fastener 129) and a locking assembly (e.g., a locking assembly 358 as shown in FIGS. 8-9B) may be able to secure the handrail assembly in position after the pivot point has been lowered to the desired location. For instance, first, second, and third locking members (e.g., the first, second and third locking members 360, 362, 364) can couple to the handrail assembly to secure the handrail assembly in position. In some examples, raising the pivot point to the first position can allow for the handrail assembly to freely pivot between the first and second angular positions.

In some examples, the pivot point of the handrail assembly can be adjusted through use of a slot (e.g., the slot 136). For instance, a slot can be formed in the bracket member, which can be used to couple to the handrail assembly. The slot can be configured so that the handrail assembly can be vertically adjusted along the length of the slot, which can thereby reposition the pivot point of the handrail assembly.

In some embodiments, steps 202 and 203 can be combined into a single step. For example, the method 200 can include the step moving the handrail assemblies from a stowed position (e.g., where the handrail assembly is in the first angular position and the pivot point is in the first position) to an operational position (e.g., where the handrail assembly is in the second angular position and the pivot point is in the second position).

At step 204, the method 200 can optionally include stowing the ramp assembly. To stow the ramp assembly, a user can remove the ramp assembly from the first and second surfaces and place the ramp assembly in the desired location for storage. In some examples, the user can transition each handrail assembly from the second angular position to the first angular position prior to stowing the ramp assembly. To transition each handrail assembly from the second angular position to the first angular position, the user can first adjust the pivot point of the handrail assembly so that the handrail assembly may be free to pivot (e.g., by raising the pivot point of the handrail assembly such that there is clearance between the end of the handrail assembly and the curb or other portion of the tread assembly). In some instances, the handrail assembly may need to be uncoupled from a locking assembly before the handrail assembly can be capable of both adjusting the pivot point and pivoting the handrail assembly. In some cases, once there is clearance between the handrail assembly and the tread assembly, the user can pivot the handrail assembly so that the handrail assembly is folded towards the tread assembly. In some examples, the handrail assembly can be pivoted 90 degrees or more relative to the upright position. In various examples, the handrail assembly can be pivoted until a portion of the handrail assembly rests against the decking surface or other portion of the tread assembly. In some embodiments, a second handrail assembly can be pivoted towards the decking surface after a first handrail assembly has been pivoted towards the decking surface. In some of these embodiments, or otherwise, the second handrail assembly can be pivoted until it rests against the first handrail assembly. Transitioning the handrail from the second angular position to the first angular position can render the ramp assembly easier to maneuver and, thus, easier to stow.

In some instances, it may be desirable to fix one or more portions of the ramp and platform assemblies in position. For example, particular regulations (the Americans with Disability Act, building codes, etc.) may require that the handrails for the ramp and platform assemblies be fixed in position so that the handrails remain accessible and secure during use. In some instances, fixing the handrails can include securing the handrails in position so that the handrails remain stable during use (e.g., when grasped by a user) and thus do not wobble, jostle, or otherwise move undesirably in use. Fixing the handrails (or other portions) of the ramp and platform assembly in this manner may prevent or greatly limit this undesirable movement, which in turn can help limit and prevent injuries or other accidents that may otherwise occur due to handrails moving unexpectedly when grasped.

In some situations, permanently fixing the handrails (or other portions) of the ramp and platform assembly can prevent the handrails from moving undesirably. However, while permanently fixing the handrails in position (e.g., through welding the handrails to the ramp and/or platform) can reliably secure the handrail in position, these permanent methods can often nullify the benefits of having a ramp and platform assembly that can easily transition between stowed and operational positions as desired (e.g., the handrails may no longer be capable of pivoting as shown in FIGS. 2A-2D). Accordingly, there exists the need for a ramp and platform assembly that can be reliably secured in position while still allowing for portions of the ramp and platform assembly to transition between stowed and operational positions.

The present disclosure can address these and other issues with respect to ramp and platform assemblies. As described in further detail herein, embodiments of the present disclosure can be directed to modular ramp and platform assemblies which include a locking assembly. In some examples, the locking assembly can be configured to secure portions of the modular ramp and platform in position to meet the standards set forth in a regulation, to limit any unwanted jostling or wobbling, or for some other purpose. In some instances, the locking assembly can be adjustable so that the locking assembly can lock a portion of the modular ramp and platform in position when desired and can be unlocked so as to allow for the modular ramp and platform assembly to be adjusted when desired. Additionally, in some examples, the locking assembly can be configured to lock the handrails of the modular ramp and platform assembly at different locations within the assembly and in different manners, which can greatly limit any undesirable movement (e.g., jostling, wobbling, etc.) of the handrails during use. These and other advantages of the present disclosure will be described in more detail herein.

FIGS. 8A-9B illustrate an alternate embodiment of a ramp assembly 300. The ramp assembly 300 can be in many respects similar or identical to the ramp assembly 100 as shown in FIGS. 1A-6E. Accordingly, like numerals for the ramp assembly 100 are used to describe like numerals for the ramp assembly 300 except in 300 series. For example, the ramp assembly 300 can include a tread assembly 302 and a handrail assembly 304, which, in some embodiments, can be similar or identical to the tread assembly 102 and the handrail assembly 104, respectively, of the ramp assembly 100. Other numerical features of the ramp assembly 300 can be similar or identical to its counterpart of the ramp assembly 100 unless described to the contrary herein.

As shown in FIGS. 8A-9B, the ramp assembly 300 can include a tread assembly 302 and a handrail assembly 304. The tread assembly 302 can provide a surface upon which a user or object can travel over. The handrail assemblies 304 can couple to the tread assembly 302 and can provide support and assistance to those who are using the ramp assembly 300. The handrail assembly 304 can include one or more post members 322 and one or more rail members 324 and can couple to the tread assembly 302 through one or more bracket members 326. Similar to the bracket member 126, the bracket member 326 can be a structural member that is configured to movably couple the handrail assembly 304 to the tread assembly 302 so that the handrail assembly 304 can transition between one or more positions relative to the tread assembly 302. A fastener 327 can be used to couple each post member 322 to a bracket member 326 to thereby couple each handrail assembly 304 to the tread assembly 302.

While the illustrated embodiment shows the ramp assembly 300 as including a single handrail assembly 304, it should be appreciated that the ramp assembly 300 can include two or more handrail assemblies 304. Furthermore, in some examples, the ramp assembly 300 can include additional components or assemblies for providing a suitable pathway for which a user or object can travel across. As one non-limiting example, the ramp assembly 300 can include a series of ramp assemblies 300 that are coupled together to form an elongated pathway. These and other arrangements of the ramp assembly 300 are within the scope of the present disclosure.

As with the handrail assembly 104, the handrail assembly 304 can transition between two or more angular positions, including a first angular position (as shown in FIG. 9A) and a second angular position (as shown in FIG. 8A). The handrail assembly 304 can also be adjusted vertically relative to the decking surface 306 through raising or lowering the post members 322 within the slots 336 of the bracket members 326. This adjustability allows for the ramp assembly 300 to transition between a first stowed position, where the ramp assembly 300 can be easier to handle, and a second operational position, where the handrail assemblies 304 can be accessible for use.

As illustrated in FIGS. 8A-9B, the ramp assembly 300 can also include a locking assembly 358. The locking assembly 358 can be configured to lock the handrail assembly 304 in one, or both, of the stowed and operational positions. Additionally, in some examples, the locking assembly 358 can be configured to limit any jostling or other undesirable movement of the handrail assembly 304 while the handrail assembly 304 is in the stowed or operational positions. While the locking assembly 358 can secure the handrail assembly 304 in one, or both, of the stowed and operational positions, the locking assembly 358 can be unlocked from the handrail assembly 304 to allow the handrail assembly 304 to transition between the stowed and operational positions. Accordingly, the locking assembly 358 can help ensure that the ramp assembly 300 meets particular regulations while also limiting any undesirable movement and maintaining the benefit of its adjustability.

FIGS. 8A-8C show the locking assembly 358 secured to the handrail assembly 304 while the handrail assembly 304 is in its operational position. As shown in FIGS. 8A-8C, the locking assembly 358 can include a first locking member 360, a second locking member 362, and a third locking member 364. Each of the first, second, and third locking members 360, 362, 364 can couple to post member 322 of the handrail assembly 304 to lock the handrail assembly 304 in position. In the illustrated embodiment, the first, second, and third locking members 360, 362, 364 are each a type of fastener that can couple the handrail assembly 304 to the bracket member 326 and/or tread assembly 302 to thereby secure the handrail assembly 304 in position. However, in other embodiments, the first, second, and third locking members 360, 362, 364 can be any member that is suitable for securing the handrail assembly 304 in position. In some embodiments, the bracket member 326 can be configured to receive each of the first, second, and third locking members 360, 362, 364. For example, as shown in FIG. 8B, the bracket member 326 can include a coupling member 357, which can include one or more apertures for receiving the first and second locking members 360, 362. Furthermore, in some examples, the bracket member 326 can include an additional aperture that extends through the first and second portions 342, 344 of the bracket member 326 and is configured to receive the third locking member 364 within.

In some embodiments, the each of the first, second, and third locking members 360, 362, 364 couple to the handrail assembly in a different manner, orientation, and location from one another. For example, as shown in FIG. 8B, the first locking member 360 can be a set screw that can be received within an aperture formed in the coupling member 357 and which, when tightened, can press upon the outer surface of the post member 322 to form a friction fit with the post member 322 and the bracket member 326 at a first point 366. As shown in FIGS. 8B and 8C, the second locking member 362 can be a nut and bolt which can extend from the curb 308 of the tread assembly 302, through an aperture formed in the post member 322, and through a separate aperture formed in the coupling member 357 so that the handrail assembly 304 can be secured to the tread assembly 302 and the bracket member 326 at a second point 368. As shown in FIGS. 8B and 8C, the third locking member 364 can be a U-pin, which can extend through an aperture of the bracket member 326 and the post member 322 so that the handrail assembly 304 can be secured to the bracket member 326 at a third point 370. In some examples, the third locking member 364 can be oriented perpendicular to the first and/or second locking member 360, 362. This arrangement of the locking assembly 358 can both secure the handrail assembly 304 in position and can also limit any unwanted movement of the handrail assembly 304 during operation. For example, the locking assembly 356 can secure the handrail assembly 304 in its operational position by preventing the handrail assembly 304 from moving undesirably (e.g., pivoting movement, vertical movement, sliding movement, etc.). Additionally, the locking assembly 358 can limit small (or large) movement of the handrail assembly 304 (e.g., jostling, wobbling, etc.) that could result from a user grasping the handrail assembly 304 during use. Accordingly, in some examples, the positioning and orientation of the first, second, and third locking members 360, 362, 364 can work together to limit the movement of the handrail assembly 304 along several different directions (e.g., along the X-axis, Y-axis, Z-axis, etc.). Thus, utilizing a locking assembly 358 with multiple locking members as described herein can greatly improve the stability of the handrail assembly 304.

While the illustrated embodiment shows the locking assembly 358 as including a first, second, and third locking members 360, 362, 364, it should be appreciated that the locking assembly 358 can include fewer or additional locking members. As one non-limiting example, the locking assembly 358 may include a fourth locking member, such as a strap, that can be used to help secure the handrail assembly 304 in addition to the first, second, and third locking member 360, 362, 364. As another non-limiting example, the locking assembly 358 can include a fastener (such as a fastener 129 as shown in FIG. 1B) which can be positioned in an aperture 335 to couple the post member 322 to the bracket member 326. These and other arrangements of the locking assembly 358 are within the scope of the present disclosure.

In some embodiments, the locking assembly 358 can be configured to secure the handrail assembly 304 when the handrail assembly is in the stowed position, as shown in FIGS. 9A and 9B, for example. As illustrated in FIGS. 9A and 9B, the second and third locking members 362, 364 of the locking assembly 358 are coupled to the handrail assembly 304 to secure the handrail assembly 304 in the stowed position. When coupled to the handrail assembly 304 in its stowed position, the locking assembly 358 can both prevent the handrail assembly 304 from transitioning to its operational position (e.g., by preventing the handrail assembly 304 from pivoting) and can also tightly secure the handrail assembly 304 against the decking surface 306 (or other handrail assembly 304) so as to prevent any undesirable movement (e.g., jostling).

To accommodate the stowed position of the handrail assembly 304, the locking assembly 358 can be adjusted relative to the operational position. For example, the second locking member 362 can be repositioned to extend from the underside of the decking surface 306 and through the post member 322 to secure the handrail assembly 304 to the tread assembly 302. Additionally, or alternatively, the third locking member 364 can be repositioned to a separate aperture formed on the bracket member 326 so that the third locking member 364 can reliably align with the through hole formed in the post member 322 and the bracket member 326 and thus secure the handrail assembly 304 to the bracket member 326.

While the illustrated embodiment shows the locking assembly 358 as including the second and third locking members 362, 364 for use in the stowed position, it should be appreciated that the locking assembly 358 can include fewer or additional locking members to help secure the locking assembly 358 in the stowed position. Additionally, in some embodiments, the ramp assembly 300 may be further modified to accommodate the first, second, and/or third locking members 360, 362, 364. As one non-limiting example, the bracket member 326 may include an arc-shaped slot for receiving the third locking member 364, which can make repositioning the third locking member 364 between the stowed and operational positions easier. These and other arrangements of the locking assembly 358 are within the scope of the present disclosure.

In operation, a user can adjust the locking assembly 358 as desired to transition the handrail assembly 304 from its stowed position to its operational position and vice versa. For example, if the handrail assembly 304 is locked in the stowed position (as shown in FIGS. 9A and 9B), a user can first uncouple the second and third locking members 362, 364, which can allow for the handrail assembly 304 to pivot as desired. The user can then pivot the handrail assembly 304 to an upright position and lower the handrail assembly 304 within the bracket member 326 relative to the decking surface 306 of the tread assembly 302. Once the handrail assembly 304 is in the upright position, the user can couple each of the first, second, and third locking members 360, 362, 364 to the handrail assembly 304 so that the handrail assembly 304 is secured at each of the first, second, and third points 366, 368, 370. As previously described, this arrangement can lock the handrail assembly 304 in position and provide a stable handrail assembly 304 for use. To return the handrail assembly 304 to its stowed position, the user can uncouple each of the first, second and third locking members 360, 362, 364 from the handrail assembly 304, reposition the handrail assembly 304 to its stowed position (e.g., raise the pivot point 333 above the curb 308 and pivot the handrail assembly 304 towards the decking surface 306). If desired, the user can then couple the second and third locking members 362, 364 to the handrail assembly 304 so that the handrail assembly 304 is secured in the stowed position.

While illustrative embodiments have been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the disclosure. While the concepts of the present disclosure are susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and are described herein in detail. It should be understood, however, that there is no intent to limit the concepts of the present disclosure to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives consistent with the present disclosure and the appended claims.

References in the specification to “one embodiment,” “an embodiment,” “an illustrative embodiment,” etc., indicate that the embodiment described may include a particular feature, structure, or characteristic, but every embodiment may or may not necessarily include that particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to affect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described. Additionally, it should be appreciated that items included in a list in the form of “at least one A, B, and C” can mean (A); (B); (C); (A and B); (B and C); (A and C); or (A, B, and C). Similarly, items listed in the form of “at least one of A, B, or C” can mean (A); (B); (C); (A and B); (B and C); (A and C); or (A, B, and C). Where appropriate, relative terms, such as “about,” “substantially,” and “approximately,” can be understood to incorporate standard tolerances.

Language such as “top”, “bottom”, “vertical”, “horizontal”, and “lateral” in the present disclosure is meant to provide orientation for the reader with reference to the drawings and is not intended to be the required orientation of the components or to impart orientation limitations into the claims.

In the drawings, some structural or method features may be shown in specific arrangements and/or orderings.
