Abstract
A portable, handheld system designed for anchoring and securing ladders, pump jack scaffolding, and walkways on pitched roofs or inclined surfaces. The invention includes three platform configurations, each with a variable pitch adjustment for leveling across multiple roof angles: (1) a ladder stop platform equipped with a 360-degree stop mechanism for multi-directional ladder stabilization; (2) a pump jack platform that provides a stable base for supporting pump jack systems and scaffolding; and (3) a walkway platform configured with parallel plank attachment bars and integrated guardrails for safe foot traffic. Each platform features anchor beds for secure attachment to structural elements like roof trusses and reinforced lateral rib members for uniform load distribution, enhancing structural integrity and load-bearing capacity across the system.

DETAILED DESCRIPTION OF INVENTION
360-Degree Ladder Stop
[0062] The present, CIP embodiment removes the pump jack configuration in FIG. 1(4) and the sleeved housings FIG. 1(7), from its parent Roof PlatformSafetyPitch non-provisional application, while retaining the core conceptual framework. Modifications include the addition of a lower L bar FIG. 2(4), which functions as an auxiliary truss-mounting element, with pre-drilled teardrop wood screw holes, enhancing structural stability and attachment to the truss system.
[0063] Additionally, the assembly incorporates an outer frame featuring a bolt and pin locking system, as illustrated in FIG. 2(2) and FIG. 2(3). In FIG. 2(3), a crossbar extends across the full width of the apparatus, aligning with the tooth grooves. This bar is positioned and secured in place using the pin locking mechanism, ensuring stability and reliability.
Pump Jack Configuration
[0064] FIG. 3 illustrates the overall pump jack configuration. The present disclosure incorporates a platform configuration with reduced surface area, tailored to enhance load capacity. By optimizing load distribution and material strength, this configuration minimizes flex and maximizes stability under varying load conditions (static and dynamic).
[0065] Platforms with smaller surface areas distribute the load more effectively onto fewer points of contact with the supporting structure, such as roof trusses, allowing for greater efficiency and reliability. This design ensures that the pump jack system maintains structural integrity while accommodating the demands of different jack-pump scaffolding applications. Overall, the tailored platform's characteristics contribute to improved performance in pump jack operations.
[0066] The I-frame base assembly comprises upper and lower L bars, FIG. 5(1), which are integrated with a vertical pitch bracket housing, as shown in FIG. 3(5) and FIG. 4(1). The horizontal members form the mounting structure of the I-frame, each featuring teardrop-shaped wood screw holes, FIG. 3(8), specifically sized to allow secure fastening to standard truss spacings, accommodating typical intervals such as but not limited to, 16-inch and 24-inch.
[0067] Pitch Bracket Configuration: The pitch bracket mechanism, FIG. 3(7), is integrated into the vertical-central portion of the I-frame, FIG. 3(5), FIG. 4(2), providing multiple selectable angle settings for precise leveling of the platform FIG. 3(2).
[0068] Locking Mechanisms: The pitch bracket is secured by an upper bolt lock, as shown in FIG. 3(6), FIG. 4(3), and FIG. 5(2), which functions as a static locking mechanism to maintain the bracket's fixed position. A lower pin lock, located at the lower section, FIG. 3(7), FIG. 4(2), and FIG. 5(3), act as a pitch-specific locking system, designed to engage and retain the selected angle, thereby keeping the pitch bracket stationary during use. Together, these locking components enhance the structural integrity and adaptability of the pump jack assembly, providing a stable and adjustable base for various pitch configurations.
[0069] The platform provides a stable and level base for attaching walking planks or other walkway systems, using side-mounted wood screws and upper cleats, as shown in FIG. 4(4), to maintain stability. It also serves as a mounting point for the pump jack pole, securing it to the base as illustrated in FIGS. 6 and 7.
[0070] FIGS. 6 and 3(1) depict the square-shaped, 180-degree right-angle attachment housing used for securing the pump jack pole, which is traditionally configured to maintain the scaffolding at right angles to the facade. This arrangement suits standard construction surfaces but lacks the versatility required for architectural designs with diagonal facades that demand more flexible scaffolding alignments
[0071] FIG. 7 depicts the circular, 360-degree interchangeable pump jack pole attachment housing, designed to permit the pump jack pole to be positioned in any orientation. This novel configuration allows the scaffolding system to align parallel to diagonal architectural surfaces. Conventional scaffolding structures are typically arranged at right angles, but architectural designs with diagonal facades necessitate diagonal scaffolding alignments to maintain parallelism with the work surface.
[0072] FIG. 8 is an assembled view illustrating the pump jack configuration in its operational state.
Walking Platform and Guardrail Configuration
[0073] The current Continuation-in-Part (CIP) application, pertaining to the walking plank and guardrail configuration, omits the 360-degree ladder stop embodiment, FIG. 1(3), the pump jack embodiment, FIG. 1(4), and the sleeved housing embodiment, FIG. 1(7) from the parent non-provisional application titled Roof PlatformSafetyPitch. Nonetheless, it retains the core conceptual framework. The present disclosure introduces a base outer frame, FIG. 2(2), incorporating a bolt-cross-bar that is first aligned with the tooth groove selection and then secured using a pin locking system, FIG. 2(3). Additionally, a lower L bar embodiment, FIG. 2(4) is included, functioning as an auxiliary truss-mounting component to improve structural stability and facilitate secure attachment to the truss system.
[0074] Wood screws are used to secure the unit to the roof trusses via pre-drilled, teardrop-shaped holes, FIG. 3(8) and FIG. 5(1). A level base is established by selecting the appropriate pitch and securing it with a locking mechanism, FIG. 2(3). Walking planks or other walkway structures are affixed to the upper platform using side-positioned, wood screws and upper cleats, FIG. 4(4). Guardrails are then inserted through designated openings in the platform, FIG. 9(4) and positioned into ladder shoes located below, FIG. 9(3). Once the guardrails are lowered into place, they are attached to the ladder shoes and locked using a pin locking mechanism, FIG. 9(6).
