Umbrella identity and configuration Establishes whether the item belongs to this model and what shelter and support configuration it has.

Shelter form and boundary

Records the physical arrangement that supports umbrella identification.

Ribbed canopy on a shaft

Record how the canopy, ribs and shaft form a deployable overhead shelter, including departures from this arrangement.

Does the canopy spread on ribs connected to a central shaft and gather towards that shaft when closed? definition
What observed feature distinguishes this item from an awning, tent, wearable rain cover or rigid shade? boundary

Intended use and support

Separates intended protection from the way the umbrella is held or mounted.

Documented shelter configuration

Record evidence for rain or shade use and identify whether the shaft is handheld or supported.

What label, instructions or other identifiable evidence establishes intended rain protection, shade use or both? provenance
Is the umbrella handheld, mounted or convertible, and which physical interface establishes that configuration? definition

Canopy coverage and performance Describes the deployed shelter envelope and the evidence for its protective performance.

Deployed shelter envelope

Records canopy geometry and its relationship to the intended shelter target.

Coverage and edge clearance

Record deployed span, canopy shape and the placement needed to cover the intended person or area.

What are the canopy spans along two identified axes when fully deployed? measurement
Where must the shaft and canopy be positioned to cover the intended target while keeping the rim clear of nearby people and objects? action

Canopy barrier condition

Separates visible canopy defects from observed or documented protective performance.

Rain and shade evidence

Record holes, seam defects and leakage observations alongside any traceable protection claims, with assessment conditions.

Where are tears, holes, detached panels or leaking seams observed, and under what inspection or use conditions? measurement
What evidence supports water-shedding or ultraviolet-protection claims for this canopy, and what remains unassessed? provenance

Frame and deployment mechanics Captures how the umbrella opens, retains its shape, closes and responds to mechanical defects.

Controls and retention

Identifies the operating sequence and the means of retaining open and closed configurations.

Deployment sequence and locking

Record applicable buttons, runner movement, catches and shaft retraction, distinguishing automatic canopy closure from complete reset.

Which controls and movements open, close and reset this umbrella according to its instructions or verified operation? action
Does the mechanism retain the fully open and intended closed configurations, or is either state unverified or unstable? measurement

Frame alignment and failure

Records defects in ribs, stretchers, joints and shaft that affect deployment or shelter shape.

Structural obstructions and inversion

Locate bent or broken members, detached attachments, jams and inversion without assuming they can be corrected by force.

Which ribs, stretchers, joints, canopy attachments or shaft sections are damaged or misaligned, and how does that affect canopy shape? measurement
If the umbrella is inverted or jammed, what supported recovery procedure applies, or should operation stop pending repair? action

Handling and use readiness Connects support, surroundings and post-use condition to practical handling and storage decisions.

Support and operating context

Assesses how the shaft is controlled and whether the intended setting permits deployment and continued use.

Supported placement and use limits

Record grip or mounting security, opening clearance and evidence for applicable use limits.

Can the user maintain a secure grip, or does the selected support demonstrably fit and retain this umbrella's shaft? measurement
Do opening clearance, observed handling stability and any documented wind restrictions support deployment or indicate closure? action

Drying, packing and return to use

Records the condition and configuration needed for carrying, storage or maintenance.

Post-use canopy and frame care

Track retained moisture, contamination, closure restraints and unresolved defects before packing or reuse.

Are the canopy folds and accessible frame areas wet, dirty or damaged, and which areas have not been inspected? measurement
What drying, cleaning or repair steps are supported for this umbrella before securing its canopy and placing it in its sleeve or storage space? action

What it is Filled

This model owns the umbrella as an individual deployable shelter object, including its canopy, supporting frame, shaft, grip or mounting interface, operating mechanism and observed readiness for use; whether dedicated parasols and fixed outdoor umbrellas share this registry entry remains unresolved.

In scope

Canopy geometry, coverage and observed ability to shed rain or provide shade
Ribs, stretchers, shaft and their assembled condition
Opening, closing, locking and telescoping behaviour where present
Handheld grip or supported mounting configuration
Wetness, damage, repair needs and readiness for storage

Out of scope

Weather systems and location-specific forecasts
The user's clothing, mobility and personal exposure
Buildings, awnings, tents and other independently modelled shelters
Separate stands, tables and ground anchors beyond their interface with the umbrella
Retail offers, purchase transactions and warranty agreements

Why it exists Filled

Enable an AI agent to recognise an umbrella, assess its sheltering and mechanical condition, and decide whether and how it can be opened, positioned, carried, maintained or stored.

Distinguishing features Filled

When deployed, a flexible canopy is spread by ribs connected to a central shaft rather than supported primarily by poles around its perimeter.
The canopy is positioned over a person or area as a local overhead shelter rather than worn as a body-covering garment.
The frame gathers the canopy towards the shaft for closure, distinguishing it from a rigid roof or permanently stretched awning.
A grip or mounting interface transfers support through the shaft; the canopy does not normally form an enclosed, occupiable shelter.
Rain protection versus shade-only use must be established from evidence about the individual item; appearance alone does not settle the umbrella-parasol boundary.

What robots and AI may and may not do Filled

Must not

Open a large umbrella in strong wind where it can lift, fly or strike people.
Leave patio umbrellas unsecured or open in storms.
Use an umbrella near overhead power lines.
Carry it at eye level in crowds.

Only with a human decision

Deciding to keep a fixed outdoor umbrella open in severe weather.

May

Open, close and store an umbrella for its user.
Report damaged frames, spokes or mounts on umbrellas it inspects.

Moral aspects Filled

Umbrellas are a small kindness; sharing them helps people in poor weather.
Wind-blown beach and patio umbrellas have caused serious injuries.

Who is affected

The user
People nearby in crowds or on beaches

Owners Filled

Steward

The person who keeps and uses it; the operator of the venue for fixed ones.

Open questions

Does vr.tr.umbrella include dedicated parasols, patio umbrellas and permanently mounted variants, or should those resolve to neighbouring registry entries?
Does an existing Vercy world model already cover this concept and therefore provide the authoritative publication?
Which evidence and assessment methods should establish rain protection or ultraviolet protection without treating marketing claims as verified performance?
How should wind-use restrictions be represented when manufacturer guidance is absent or uses conditions that cannot be compared directly?
Which mechanism-specific recovery and repair procedures can be supported by authoritative instructions, especially for inversion, spring mechanisms and telescoping shafts?
