Tripod-Mounted Telescoping Camera Rig with Nested Sliding Modules

PUBLIC DISCLOSURE & TECHNICAL DESCRIPTION

Title:
Tripod-Mounted Telescoping Camera Rig with Nested Sliding Boxes and Counterweights

Inventor:
Samir Eltom

Date of Disclosure:july 5 /2025







🔹 ABSTRACT:

This invention is a modular, tripod-mounted camera rig that allows extended horizontal movement of a mounted camera through a telescoping nested box system. The system comprises three open-top rectangular boxes—C inside B inside A—wherein the camera slides side-to-side across a total distance of up to 5 meters, all without requiring any ground tracks. The outer box (Box A) remains mounted on a tripod. The system includes counterweight attachment points on both ends of Box A to maintain balance during lateral extension, similar to a jib or crane.

🔹 TECHNICAL DESCRIPTION

1. Overview:

The invention enables smooth lateral motion of a camera rig across a wide range (up to 5 meters) using a nested, telescopic motion design, supported entirely from a stationary tripod or stand. Unlike conventional sliders or dollies that require floor tracks, this design uses a series of nested sliding modules mounted above ground.

2. Structure:

• Box A (Outer Box):

  • The largest and heaviest frame, approximately 1 to 1.5 meters wide.

  • Made of rigid materials (e.g., aluminum, carbon fiber).

  • Mounted on a tripod or fixed stand.

  • Internally houses Box B on internal rails or wheels.

  • Includes designated counterweight attachment points at both the left and right ends, designed to hold weights of 2.5 to 5 pounds, improving balance when the system is extended laterally.

• Box B (Middle Box):

  • Slightly smaller than Box A.

  • Mounted on wheel-based or rail-based tracks inside Box A.

  • Slides left and right within Box A.

  • Contains Box C.

• Box C (Inner Box):

  • The smallest module.

  • Holds the camera and moves inside Box B.

  • Designed with smooth gliding rails or wheels for precision control.

  • All three boxes are open at the top to accommodate camera mounting and free movement.

3. Motion and Function:

  • The camera in Box C moves horizontally within Box B.

  • Box B moves within Box A.

  • The combined sliding action provides a total camera travel distance of up to 5 meters from left end to right end.

  • Box A remains stationary on the tripod.

  • Counterweights are mounted on each side of Box A to counterbalance the extended weight and prevent tipping or instability.

4. Optional Features:

  • Locking magnets or clamps at terminal positions.

  • Collapsible versions for portability.

  • Modular extensions for different setups.

  • Motorized sliding modules for remote tracking.

  • Integrated spirit level and friction control.

🔹 CLAIMS (Suggested for Filing)

  1. A camera rig comprising three nested rectangular boxes wherein:

    • A smallest box (Box C) slides within a middle box (Box B);

    • The middle box (Box B) slides within an outer box (Box A);

    • The outer box (Box A) is mounted on a tripod or fixed stand;

    • The total lateral movement achieved by the camera exceeds four meters without using ground rails or floor-based tracks;

    • Wherein the outer box includes designated left and right attachment points for counterweights between 2.5 and 5 pounds.

  2. The rig of claim 1, wherein the motion of Boxes B and C is achieved through internal wheel-based or rail-based systems.

  3. The rig of claim 1, wherein each box is open from the top to allow unobstructed mounting and movement of the camera.

  4. The rig of claim 1, wherein the rig is modular or collapsible for ease of transport and setup.

  5. The rig of claim 1, further comprising stabilizing extensions or outriggers to prevent tipping during maximum lateral extension.

  6. The rig of claim 1, wherein the counterweight attachments comprise side arms, hooks, or sleeves to hang sandbags, adjustable weights, or tension-balanced weights.

🔹 DRAWING DESCRIPTION (Refer to Your Sketch)

  • Label A: Outer box (tripod-mounted)

  • Label B: Middle box (slides in A)

  • Label C: Inner camera box (slides in B)

  • Left/Right ends of Box A: Counterweight mounts

  • Open top: For camera installation

  • Motion: Left–right, total ~5 meters

This disclosure establishes public prior art and can be used to:

  • File a Provisional Patent Application

  • Present to manufacturers or collaborators under NDA

  • Publish online as a timestamped disclo

Foldable Dual-Hook Adjustable-Spacer Hanger with Centering Rotation

Image
  Abstract A garment hanger with two hooks spaced apart by a selectable distance (3–10 cm) to provide bilateral garment clearance. Each hook is mounted on a foldable carrier that can pivot to bring the hooks together for compact storage. The hook carriers and/or the garment-supporting member are configured to rotate about a vertical axis (≈90°) so that the garment-supporting bar or arms remain centered under the closet rod in both the spread and collapsed configurations. The invention allows a single hanger to function either as a space-creating dual-hook hanger or as a conventional single-hook hanger, without causing the garment to shift off-center when collapsed. Background Closet rod spacers and fixed dual-hook hangers exist, but they do not (a) allow adjustable spacing, (b) fold flat for shipping or storage, or (c) keep garments centered when collapsed. When traditional dual-hook hangers are modified for storage, garments hang off-center, creating imbalance and wasted s...

Dual-Hook Closet Hanger Providing Bilateral Garment Spacing

Image
  Provisional patent application draft Abstract A garment hanger having two spaced hook portions configured to engage a single closet rod at two separated locations, and a garment-supporting member suspended substantially at the midpoint between the hook portions. The geometry enforces a preset lateral spacing from adjacent hangers on both sides. Embodiments include indexed adjustable spacing , anti-rotation rod saddles , and compressible bumpers . Field Closet hardware; garment hangers; wardrobe organization. Background Closet spacing has been addressed mainly by separate spacers/dividers attached to the rod, or by dual-hook hangers for clotheslines. Add-on spacers add clutter and are easy to misplace, while clothesline hangers are not optimized for closet rods. There remains a need for a single hanger that both supports a garment and inherently preserves bilateral clearance on a standard closet rod. (See, e.g., hanger spacer devices and spacer tapes; dual-hook win...

Quarter-Curve Side Plate for Efficient Dining Space and Side Dish Serving

  Public Disclosure Title: Quarter-Curve Side Plate for Efficient Dining Space and Side Dish Serving By: Samir Eltom Date: [Insert Today’s Date] Description: This invention introduces a novel plate accessory designed to complement traditional round dinner plates. Rather than placing separate round side dishes that take up additional table space, this invention presents a quarter-circle curved plate—a side-serving plate that neatly hugs the outer curvature of a standard round plate. Key Features: Form: A curved quarter-circle shape that mirrors the arc of a round plate. Placement: Designed to be placed along the edge of any classical round dinner plate, offering a natural extension of the main dish area. Size: Approximately 5 to 10 cm in width from inner curve to outer curve and 2 to 4 cm in depth, enough to hold sauces, dips, small salads, or fries. Space Efficiency: Unlike traditional small bowls or dishes, which occupy unnecessary table area, this curved plate ...
