Detachable Chair-Integrated Shield System For Schools and Workplace By RF Safe

This design integrates a detachable ballistic shield seamlessly into the back of a high-back office or classroom chair. From all angles, the chair appears like a standard chair, with only a discreet horizontal handle visible on the rear surface. The shield is secured inside the chair by a locking mechanism, which must be pressed to disengage.

Once unlocked, the shield can be withdrawn vertically through an opening at the top of the chair back, similar to bread rising from a toaster. The handle serves dual purposes: in normal use, it functions as a convenient grip to move the chair, and in emergency use, it allows the shield to be quickly pulled free.

The shield can be used in two defensive modes:

  1. Stationary Cover – The shield remains in place within the chair, allowing the user to crouch or hide behind the chair for immediate protection.

  2. Mobile Protection – By releasing the lock and pulling the handle upward, the shield can be removed and carried, giving the user portable cover while navigating to a secure exit, locking or unlocking doors, or guiding others to safety.

This system provides an invisible layer of security without altering the familiar appearance of a classroom or office environment, while ensuring teachers or staff can quickly deploy protective measures when necessary.

ABSTRACT

A chair with a high backrest conceals a thin protective shield within a vertical cavity of the backrest. The chair appears conventional from all angles with the exception of a discrete rear handle coupled to the shield and a single top exit opening. A locking mechanism retains the shield in a stowed position for normal chair use. Upon actuation of a release, the shield is withdrawn vertically through the top opening, analogous to bread rising from a toaster, by grasping the rear handle. Guide structures within the cavity constrain shield motion, align a crossbar handle via narrow vertical slots, and stabilize the shield so the chair itself can serve as stationary cover. The system provides immediate stationary protection and rapid transition to mobile protection for securing entry points or evacuating occupants.

FIELD OF THE INVENTION

The invention relates to personal protective equipment integrated into furniture, and more particularly to a detachable ballistic or impact‑resistant shield stowed within a chair back and deployable through a top exit slot.

BACKGROUND

Classrooms and offices commonly include high‑back chairs that offer no integrated means of immediate protection. Stand‑alone shields take space, draw attention, and are often not within arm’s reach when needed. There is a need for a non‑obtrusive, always‑present protective device that looks like ordinary furniture yet can be deployed in seconds, and that also allows either stationary cover or mobile cover while navigating to secure or exit an area.

SUMMARY

The invention provides a chair‑integrated shield comprising:

  1. A chair with a high backrest defining an internal cavity accessible only through a top exit opening.

  2. A thin protective shield sized to slide within the cavity in a stowed configuration.

  3. A rear crossbar handle coupled to the shield and exposed through two narrow rear alignment slots, allowing the handle to be grasped while the shield is stowed.

  4. At least one locking mechanism (e.g., spring latch, push‑button, keyed or electronic release) that retains the shield until deliberately actuated.

  5. Guide rails/tracks and bottom and/or lateral stops within the cavity that guide and stabilize the shield during insertion, stowage, and extraction.

From any side the chair appears standard, with the only visible elements being the rear handle and subtle slot outlines. When the release is actuated, the user grasps the handle and withdraws the shield upward through the top opening. The chair may itself be used as a stationary barrier with the shield stowed; alternatively the shield is removed to provide mobile protection while moving to lock/unlock doors or scout an evacuation route.

Optional features include a viewport (ballistic window), integrated task/inspection light, camera, strap or forearm brace, detent indexing, sensor‑triggered tamper indicator, and retrofit brackets for existing chairs.

REFERENCE NUMERALS

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Overall Configuration

Referring to FIGS. 1–4, chair 10 includes a backrest 16 enclosing an internal cavity 20 opening only at its top exit opening 22. The cavity is sized and shaped to receive shield 26. In the stowed position, the shield is fully concealed within backrest 16 such that the chair appears conventional 360° about its perimeter. The only visible elements are (i) the rear crossbar handle 28, which is exposed through two narrow alignment slots 24a/24b, and (ii) the subtle outline of top opening 22.

Shield and Guide System

Shield 26 is a thin, generally planar panel with a thickness appropriate to the desired protection level. The panel may be flat or slightly concave to mate with the interior of the chair back. Guide rails 30 and liner 46 constrain the shield to linear travel, minimize rattle, and distribute loads into the chair frame. A bottom stop 36 prevents over‑insertion; a top lip/hood 58 visually conceals the opening and provides a grasp clearance when the shield is partly elevated.

The crossbar handle 28 resides within a handle recess 42 in the shield. In the stowed configuration, handle 28 projects through alignment slots 24a/24b, permitting the user to grasp the handle while also preventing lateral twisting of the shield. This dual‑slot interaction resists torque and stabilizes the shield during both stationary and mobile use.

Locking/Release

A spring‑biased latch 32 engages a catch 34 on the shield. To deploy, the user actuates latch 32 (push, pull, or squeeze), disengaging the catch. With the other hand (or same hand), the user grips handle 28 and slides shield 26 upward through the top opening 22. Optional detent 48 offers tactile indexing at stowed and semi‑deployed positions. Latch 32 may be manual, keyed, coded, or electronically controlled; optional sensor 56 and indicator 60 can signal deployment or tampering.

Modes of Use

  1. Stationary Cover: With the shield stowed, the chair can be positioned between the user and a threat; the shield’s mass and rigidity, constrained by guides 30 and slots 24a/24b, provide immediate cover without extraction.

  2. Mobile Cover: When movement is needed, the user releases latch 32 and withdraws the shield completely for handheld use (FIG. 5), optionally employing strap/brace 52.

SUMMARY

Detachable Shield Chair — Top‑Exit Slot Design
A high‑back chair hides a thin protective shield inside the backrest. From all sides it looks like a normal chair. A small rear handle—part of the shield—sticks out through two vertical slots. Press a release button, grab the handle, and the shield slides straight up out of the top (think bread rising in a toaster). Use the chair as immediate stationary cover, or pull the shield free for mobile protection while securing doors or guiding people to safety. Optional viewport

The Chair That Turns Into a Shield: A Simple, Powerful Layer of Protection for Classrooms, Banks, and Public Venues

Elevator pitch (2 sentences):
This is a high‑back chair that looks completely ordinary—until you press a small release button. Then, a thin, ballistic‑rated shield slides straight up out of the top (like bread rising from a toaster), giving instant cover you can use while stationary or carry as you move to secure doors and lead people to safety.

Why a Chair?

When seconds matter, protection needs to be where people already are—not in a closet, not down the hall, and not locked behind a case. A teacher, teller, or speaker on a stage is almost always near a chair. That makes the chair the perfect, non‑intimidating place to hide a lifesaving tool that’s instantly accessible and easy to understand.

Key insight: if you can grab the back of the chair, you can grab the shield.

What It Is (in plain English)

Important note: “ballistic” performance depends on materials and construction. Production units should be tested and labeled to recognized standards (e.g., NIJ levels). No device guarantees safety; this chair adds a practical layer of protection that’s always at hand.

Why Schools Want It

1) Immediate, intuitive protection

In real incidents, people reach for what’s nearest. The teacher’s chair is already within arm’s reach. There’s no learning curve: press, pull, cover.

2) Doesn’t change classroom culture

There’s no wall‑mounted gear to draw attention. The classroom still looks and feels like a classroom, which helps teachers, parents, and students feel normal day‑to‑day.

3) Two modes—one device

4) Fits incident command

The shield supports lockdown, evade, and evacuate steps without asking educators to master new equipment.

5) Scales quietly

Districts can pilot a few classrooms, learn, and expand—no construction needed.

Why Banks, City Offices, and Stages Want It

How It Works (the simple steps)

  1. Stationary Cover Mode

    • Stay low, roll or pivot the chair to keep it between you and the threat.

    • Use the chair’s mass plus the shield inside the back for immediate protection while you secure doors or contact help.

  2. Mobile Cover Mode

    • Press the release button on the chair back.

    • Grab the rear handle (it’s always visible).

    • Slide the shield straight up through the top opening.

    • Hold the shield in front of you as you move: to lock/unlock an entry, lead students, or check a hallway.

    • Optional features (viewport, light, strap) improve visibility and control.

  3. Re‑stow

    • When safe, slide the shield back into the top opening; it indexes and locks with a click.

Realistic Scenarios

Classroom Lockdown (Door Closed)

Classroom Evacuation (Directed by Admin)

Bank Branch Incident

City Council Meeting or University Lecture

Reception Desk with Glass Partition

Design Features That Matter

Material note: Production shields should be built and labeled to a clear protection level (e.g., NIJ IIIA, etc.). Actual materials may include composite laminates (e.g., aramid/UHMWPE), metals, or hybrid stacks with anti‑spall layers. Always verify with certified testing; marketing must never over‑promise.

How to Use It in School Safety Plans

  1. Placement: Position the teacher’s chair within a single step of the primary teaching position and within sight of the door.

  2. Training (10-minute module):

    • Recognize the chair and release button.

    • Practice Stationary Cover positioning and Mobile deployment.

    • Rehearse two movements: to the door, and to the safer corner/secondary room.

  3. Drills: Add “chair‑shield step” to existing lockdown and evacuation drills.

  4. Student briefing: Age‑appropriate explanation—“This chair has extra safety built in; your job is to follow the teacher’s directions.”

  5. Maintenance: Monthly quick check (see checklist below) and annual inspection.

INSTANT COVER

  1. Roll or pivot the chair between you and the threat.

  2. Stay low; direct students to move to their safe area.

GO MOBILE
3) Press the release button.
4) Pull the rear handle straight up to remove the shield.
5) Keep the shield between you and the threat while you lock the door, move to a safer room, or lead evacuation.

AFTER
6) Re‑insert from the top until it clicks.
7) Report use to administration for inspection/replacement if required.

Maintenance & Inspection Checklist

Addressing Common Questions from School Boards & Safety Committees

Will students notice it?
No more than a normal chair. The only visible differences are a small rear handle and subtle slots.

What about misuse?
A child‑resistant, two‑action release can be specified. The shield is also retained by the rail system; casual tampering won’t deploy it.

How heavy is it?
Depends on rating and size. Designs target a comfortable one‑hand lift for most adults; optional forearm strap spreads load.

Does it block egress?
No. It occupies the same footprint as a chair already present. Rolling the chair should never block doors; this is covered in training.

Liability and standards?
Products should carry clear protective ratings and usage guidance and be incorporated into the district’s written emergency plan and drills.

Cost vs. benefit?
Compared to adding dedicated ballistic partitions, the chair‑shield leverages furniture you already buy, offers dual use (chair + protection), and can be deployed in under 2 seconds after brief training.

Procurement & Rollout Playbook

  1. Pilot 3–5 rooms across grade levels; involve the SRO/safety officer.

  2. Collect feedback on chair height, handle feel, and deployment speed.

  3. Set a standard (e.g., “every classroom has one” or “teacher & aide chairs equipped”).

  4. Train staff and include in drill scripts.

  5. Communicate with families: “This looks like a normal chair. It gives staff a tool to keep children safe without changing the classroom environment.”

Variants for Other Environments

Human Factors & Training Notes

Technical Overview (for RFPs and purchasing)

Again: protective performance depends on chosen materials and construction; specify required rating and demand certified test results.

Why This Fills a Needed Niche—Today
