EASY OPEN DOOR – Patented
What is EASY OPEN DOOR – Patented?
Basic Definition
EASY OPEN DOOR – Patented is a patented, specialized door mechanism designed for shipping and storage containers, which fundamentally redesigns the standard door opening system with emphasis on user comfort and increased accessibility. Instead of the traditional system with multiple locking bars, it uses a simplified, ergonomic design that dramatically reduces the physical effort and time required for opening the container. This innovation is primarily intended for the secondary market — that is, where containers are used for storage, commercial or residential purposes, and where easy access is more important than the requirements for repeated maritime transport.
Patent Protection – Meaning of the “Patented” Designation
The inclusion of the word “Patented” is key. It means that EASY OPEN DOOR is a protected solution (for example, by utility model, design patent or patent). This status guarantees users consistent quality, a tested system and operational reliability. The patent typically protects a unique combination of these elements:
- one, reinforced locking bar (instead of four),
- extended lever with ergonomic grip,
- integrated lubrication points on hinges (so-called zerk-fittings),
- specially designed security lock.
Patent protection simultaneously distinguishes EASY OPEN DOOR from common, uncertified modifications.
Mechanical Details and Key Elements
One Locking Bar
| Feature | Description |
|---|---|
| Number of bars | 1 (instead of 2 or 4) |
| Material | High-strength steel, reinforced profile |
| Location | Right door (first to open) |
| Security | Same security level as multi-point system due to reinforcement and special lock |
- Reinforced construction: This single bar is significantly stronger than standard bars, ensuring high resistance to forced entry and meeting safety requirements.
- Simplified operation: Only one mechanism needs to be operated, which simplifies the entire procedure.
Extended, Ergonomic Handle
| Feature | Advantage |
|---|---|
| Handle length | Longer than standard doors |
| Grip material | Rubber with anti-slip finish |
| Mechanical advantage | Larger lever means less force needed to turn |
- Higher lever: The length of the handle provides the user with considerable mechanical advantage – less force is needed to unlock the lock due to the physical principle of leverage.
- Anti-slip ergonomics: The handle surface is made of softened, anti-slip material, which you will appreciate especially in rain, frost or when working in gloves.
Integrated Lubrication Fittings (Zerk Fittings)
- Maintenance without disassembly: Each door hinge is equipped with a lubrication fitting, into which lubricant can be applied directly with a standard grease gun.
- Long-term durability: Regular lubrication prevents hinge seizing (a common problem with standard doors), which is essential for maintaining easy opening over the years.
Security Lock and Cam Keeper
- Special security mechanism: At the bottom of the bar is a robust cam and keeper, which ensure firm and secure door closure.
- Water and dust tightness: Maintaining the tightness of container doors is key – quality cam and keeper help maintain the environment inside the container without water or dust ingress.
The Problem EASY OPEN DOOR Solves: Standard vs. EASY OPEN Doors
Why Are Standard Container Doors Problematic?
Standard doors on ISO containers were designed primarily for extreme durability and safety during maritime transport. Their construction consists of several (usually four) strong vertical locking bars, strong rubber seals and heavy hinges.
- Operation: To open, you need to release (turn) two to four bars, which often resist due to sealing or neglected maintenance.
- Physical demands: Handling heavy doors and stiff mechanics requires strength and technique. For elderly people, women, or people with disabilities, it is often nearly impossible.
- Time consumption: An experienced worker opens standard doors in 30–60 seconds, less experienced workers take even longer.
Direct Comparison: EASY OPEN DOOR vs. Standard Doors
| Parameter | Standard Doors | EASY OPEN DOOR – Patented |
|---|---|---|
| Number of locking bars | 2 on each door (4 total) | 1 reinforced on right door |
| Operation | 2–4 short steel handles | 1 extended handle with rubber |
| Required force | High, often with both hands | Low, with one hand |
| Average opening time | 30–60 s | 5–10 s |
| Maintenance | Manual, often neglected | Integrated lubrication points |
| Primary use | Maritime transport, long-term storage | Storage, rental, projects with frequent access |
| Accessibility | Physically demanding | Accessible to general public |
| Security | High (multi-point locking) | High (reinforced mechanism) |
Benefits for the Secondary Market
The EASY OPEN DOOR system is designed primarily for the secondary market — that is, for container storage, rentals, modular construction, where frequent access is a key requirement. It increases user comfort, saves time and health, and makes the container an attractive choice for a wide range of customers.
Applications and Uses of the EASY OPEN DOOR System
Commercial and Retail Storage
- Quick access: Employees can easily and quickly retrieve goods or materials, which increases operational efficiency.
- Security: After closing, the container remains as secure as the standard version.
Construction Sites and Industrial Applications
- Time savings: On a construction site, time is money — quick opening means less downtime.
- Simple operation: Workers can open doors even with full hands or in work gloves.
Residential and Personal Use
- Accessibility for everyone: Even children, seniors or less physically fit users can operate it without problems.
- Garden sheds, workshops, hobby use: The container becomes a full-fledged extension of the home thanks to easy access.
Container Rental and Sales

Innovation and the Future of Container Accessibility
EASY OPEN DOOR is part of a broader trend of “humanizing” containers — that is, adapting them to be suitable not only for transport, but also for everyday use. Other innovations include:
| Innovation | Description | Advantages/Disadvantages |
|---|---|---|
| Roll-up doors | Similar to garage doors, quick access | Speed, simplicity / lower security and tightness |
| Personnel (man) doors | Built-in doors for pedestrians on the side of the container | Comfort, frequent entry / need to keep main doors for large items |
| Side-opening | Double-leaf doors along the entire length of the container | Access by equipment (forklift), handling of long goods / higher purchase price, more complex construction |
| Electronic and smart locks | Keypad, chips, remote control | Comfort, access logging / higher price, need for power supply |
Expected development will lead to further expansion of smart and ergonomic solutions that will make containers accessible to non-technical users.
