1. Benefits Of Floor Springs

  • Floor springs are virtually invisible

Floor springs are the perfect product for glass doors as they are virtually invisible unless you really take a close look. They blend seamlessly into the floor without spoiling the attractiveness of the look of its surface. They also provide a clean and attractive finish that doesn’t ruin the line of the door or detract from its design. Of course, they can also be installed on wooden, stainless steel and aluminium doors too. That is why they are suitable for both indoor and outdoor use.

Because of their extremely shallow installation height, floor springs are suitable for any kind of floor. Their cover plates can be made in a variety of styles to mix with existing door furniture. Choose from stainless steel, bronze, antique brass, or follow your own bespoke style in anything from modern to vintage.

  • Floor springs are incredibly able to adapt to many functions.

They also can be used on both single and double-action doors. They are pretty much the only option when it comes to oversized doors, as conventional closers can’t cope with the sheer weight of floor-to-ceiling doors. Heavy doors can hurt people in areas prone to high winds, so having floor springs in place controls the opening and closing of the door. This helps to prevent the doors from shutting forcely and loudly.

You can adjust them to close at the speed and the force that you choose. But, they can also be provided with an electromagnetic hold-open function. This makes them usually useful for high traffic areas. You can connect the springs to your fire warning, meaning they will automatically close the door in case of a fire. This is just one of the reasons why they’re such popular options for smoke protection and fireproof doors.

2. Choosing The Right Floor Springs

Because there is such a wide range of product when it comes to floor springs, it’s important to consider a few factors before buying a unit.

  • Door width and height – as above-mentioned, floor springs are suitable for glass doors but are the perfect choice for any heavy or oversized (floor to ceiling) doors.

  • Door location – Floor springs are ideal for those internal doors, such as those found in hospitals and commercial kitchens, that need to swing both ways. Certain external doors need to close automatically or be kept opening, depending on the circumstances. So chose the right floor springs for this purpose. Emergency fire doors need to be kept closed in case of a fire, so make sure you choose the right non-hold open floor spring units.

  • Traffic volume – In locations where traffic volume is medium or heavy, overhead door closers are commonly used as they are extremely durable. They are available in choices for exterior and interior doors and are actually amongst the most popular door closers available today. Floor springs work well for very heavy traffic doors as they are much more durable than overhead closers.

3. The Technical Stuff – How Floor Springs Actually Work

Floor springs work using what we call a CAM action mechanism. When the door is opened, in spite of in which direction, the bottom arm, which is fixed to the door, rotates the CAM spindle. This, in turn, rotates the CAM itself. The CAM is linked to the piston and, when it’s rotated, pulls the piston head. When this happens, the compression springs and oil become flatten by pressure. A compressed spring stores energy. In this situation, the oil flows to the other side of the piston head.

If the door is opened to an 90° angle, the CAM engages the arrester pin, which then keeps the door open until it is disengaged by applying force to the door.

If the door isn’t opened to an angle of 90° , the compressed spring pushes the piston head which then closes the door.
