Description

[Technical Field]

[0001] The present invention relates to a mechanism for simultaneously expanding and contracting the width of ladder-like structures. Summary of the Invention [Problem to be solved by the invention]

[0002] Create a mechanism that allows multiple items, such as a shelf for Tupperware, to expand and contract simultaneously.

[0003] The invention utilizes the connecting points in the center of a magic hand-shaped component with a structure in which many diamonds are arranged and the entire component is uniformly stretchable, bridging multiple components.

[0004] This allows the entire structure of a multi-tiered shelf, an egg slicer, or a tool for marking at equal intervals to be easily and simultaneously extended and retracted.

[0005] The axis parts of the connecting points lined up in the center of the magic hand-shaped component, which is made up of many connected diamonds, are bridged to create a ladder-like structure.

[0006] The bridges can be adjusted to every other bridge, etc.

[0007] For flat objects such as egg slicers, two magic hand-shaped components are connected, and for three-dimensional products such as shelves, a bridge is further connected to create a box shape.

[0008] A tool for simply marking dots at equal intervals can be achieved with a single magic hand-shaped component.

[0009] The rows on both ends are connected in a way that allows them to be fixed in position (by moving overlapping pipes and fastening them with screws, etc.). There is a structure that looks like a radio antenna, with a large difference in expansion and contraction.

[0010] To stabilize it, it can be made with strong materials with high precision, made into a shape that can be used at around a medium degree of stretch, and the number of magic hand-shaped parts can be increased.

[0011] It is also possible to use a rack and pinion structure with multiple components of different lengths and diameters stacked on top of each other (a multi-stage cone shape with racks of various lengths and diameters). This requires space for the remaining racks, but is thought to provide greater stability. [Industrial Applicability]

[0012] It can be widely used as an extension mechanism for ladder-like arrangements.

[0013] It can be applied to shelves and equipment that lifts stacked containers at equal intervals.

[0014] Possible applications for this technology in cutting equipment include egg slicers (the same principle can be used for soft foods such as kneaded foods), noodle makers, devices for cutting squid, bread slicers, etc.

[0015] It can be applied to tools such as rulers lined up in parallel, or tools that mark at equal intervals.

[0016] For xylophones and metallophones (described below), the spacing between the drums is wider and the sticks are larger, making them easier for beginners to play.

[0017] It can also be applied to items for which width has not been discussed much (both for adults and children), such as stringed instruments, xylophones, metallophones, keyboards, colored pencil holders (which can be set up at any interval when in use), and other tool holders.

[0018] This rule can be applied to blinds in the form of bamboo screens, although they cannot be rolled up.

[0019] Other possible uses include the following: Hair combs, brushes, comb-type agitators, -Flying object trap Drainage channel debris filters - Bookends (CDs, etc.) · Hangers · Clothes racks (drying, display), noodle drying, dried gourd, etc. Draining board, grilling board (length and width if not woven) · Line drawing connected Lawn spikes, a tool for opening leather stitches - Thin tool holder (for wrenches, etc., thin tools have a large effect on the difference between storage and use) Rice planter · Mannou (Make it strong) ·rake ·Senbako A bamboo screen used as a washing board Sieve (length and width if not woven) Row of bicycle parking spaces Yagi antenna Used like a rake, but arranged parallel and with adjustable spacing Tree chimes, sleigh bells Guiro-based instruments (flat, but also irregularly shaped instruments) A series of metal rods used to remove mud from shoes Heat exchanger (fins) ·louver Abacus

[0020] Furthermore, it can be used for the following purposes: Brush (stretch small circles to change density) Mont Blanc-type, small diameter sauce squeezer (connected to the nozzle with a flexible tube) A row of firework launch tubes · A lineup of wind chimes, carp streamers, lanterns, candles, decorations, etc. -Lighting, illumination, lasers, etc. -Fountain row (water supplied by flexible tubes) Simple building frameworks such as lodge-type tents, greenhouses, and agricultural tunnels A simple structure frame shaped like a carport or fart-shaped sunshade - Sword stand (the density in the fixed direction is the midpoint of the range of density in the movable direction) Insect cage (opening on fixed surface) Test tube rack (adjustable spacing) A ring-shaped device for holding canned drinks upright (height adjustable) Umbrella stand (widen the gap to prioritize drying) A cylindrical object with a series of clips for bundling and organizing wires - Items with a series of hooks (such as bags hung in alphabetical order) Cylindrical lantern that expands and contracts evenly Playground equipment such as monkey bars (make them sturdy) A portable athletic structure made of logs - Play equipment that involves crossing upright cylindrical logs (even if placed on all the zigzag joints) Shiitake mushroom cultivation beds (adjust humidity by spacing, open when harvesting, etc.) - Rows of planters or pots (which can be separated as they grow) An accordion with a long, straight, and uniformly stretchable accordion part

[0021] Furthermore, the following uses are also conceivable: Rows of dolls, rows of statues Rows of red cones Arrangement and storage of handbell-type instruments Snare drum resonator wire spacing Traps and fishing nets Arbitrary arrangement of pedestals for exhibits, etc. Shooting gallery prizes, etc. Lace curtains - Numerous staplers and hole punches - A letter holder with multiple tiers -An extendable comb with a different color every 5-10 pieces that can be used for counting (such as a plate) Electrostatic mop (stretches and shrinks small units to change density) - Dividers for placing coins in groups of about 5 in the coin grooves to make counting and removal easier Test tube or roll-type brushes (can be stretched and contracted in small increments to change density) Lace curtain shower (water supply via soft tube) - Magnets, suction cups, pins for attaching to the wall, etc. - A luggage rack or shelf that can be extended to any length. A basket whose width can be adjusted depending on the amount of contents (for shopping, etc.) Wire mesh panel with adjustable width depending on the size and amount of items to be hung S-shaped hooks lined up side by side · Able to attach evenly spaced type and expand / contract -Date stamp system with adjustable allocation intervals

[0022] Furthermore, the following is also possible: Cultivator (the tines should not be tilted) Shredder (it seems worth changing depending on the size of the paper and card, etc.) - A device with scissors attached that can be used like a shredder Razor-type cutter with an outer blade and multiple inner blades A rolling massager with many rollers Louvered wall gap - Items that can be used for distribution on long tables, etc. (Mechanisms that clamp all items together are used for drying clothes, etc.) Items that can be transported and distributed by suction from above (vacuum is done with a soft tube)

Claims

1. A mechanism that allows the width of a ladder-like structure to be changed all at once.

2. Multiple shelves or lifting equipment that can change widths in one go.

3. A tool for drawing or marking lines at equal intervals, the width of which can be changed all at once.
