What is in a floor spring?
A floor spring, also known as a floor closer or floor hinge, is a mechanical device used to control the closing and opening of doors, particularly heavy or large doors. It is typically installed within the floor beneath the door and is designed to provide a controlled and smooth movement, enabling the door to close automatically after it's been opened and to remain closed when not in use. Floor springs come in various designs and sizes to accommodate different door weights and sizes. They are commonly used in high-traffic areas such as office buildings, airports, hotels, and shopping centers to ensure that doors close securely and efficiently, providing convenience and safety for building occupants.
Here is the tables shows the main components of a floor spring:
①Chassis: The outer casing body that contains the internal components of the floor spring. It is usually installed with the cement box within the floor, making it largely hidden from view.
②Spring Mechanism: The spring mechanism provides the necessary force to close the door. It consists of a spring or a combination of springs that store energy when the door is opened and release it to close the door when it's let go. Our spring made of high-quality spring steel, the optimal production process is selected, heat treated and hardened to ensure the closing force and improve the service life of the product.
③Control Valve: A control valve allows for adjusting the closing and latching speed of the door. By controlling the flow of hydraulic fluid, users can set the desired speed and force with which the door closes. This ensures that the door closes smoothly without slamming.
④Hydraulic Oil: Most modern floor springs use hydraulic fluid to control the door's movement. The fluid flows through the control valve and regulates the speed and force of the door's closing motion. Our hydraulic oil is selected from Germany's "FUCHS" company, whether it is low temperature or high temperature, it can guarantee normal operation and greatly improve the service life of the floor hinge.
⑤Bearing: The use of power metallurgy oilimpregnated bearings or needle bearing greatly reduces the friction between the gear shaft and the shaft, which improves the efficiency of the floor hinge and makes it easoer to open the door.
⑥Cover Plate: A cover plate is often included to conceal the floor spring mechanism and create a more aesthetically pleasing appearance.
⑦Adjustment Screws: These screws are used to fine-tune the closing and latching speed, as well as the force required to open the door. By adjusting these screws, the floor spring's behavior can be customized to suit the specific requirements of the door and the building.
How to install a floor spring?
Installing a floor spring can be a complex process and requires careful attention to detail to ensure proper functionality and safety. It's recommended to have experience with door hardware installation or to consult a professional if you're not familiar with the process. Below is a general outline of the steps involved in installing a floor spring:
Tools and Materials You'll Need:
①Floor spring unit
②Mounting hardware (provided with the floor spring)
③Hydraulic fluid (if required)
④Power drill and appropriate drill bits
⑧Pencil or marker
⑨Wrenches and other basic hand tools
⑩Cover plate (if included)
1.Prepare the Door:
Measure the door's dimensions and weight to select an appropriate floor spring model.Determine the desired location for the floor spring on the door's bottom edge. This is typically around the center of the door's width.If the door has notches or holes for the floor spring's pivot, make sure they align with the chosen location.
2.Prepare the Floor:
Measure and mark the intended installation spot on the floor. Ensure that it's aligned with the door's pivot point. Check the manufacturer's instructions for recommended installation clearances and dimensions.
3.Install Mounting Hardware:
Using the provided mounting hardware, mark the locations for the anchor points on the floor and drill holes as needed. Ensure the holes are clean and free of debris.Insert the anchor sleeves into the holes and secure them using the appropriate fasteners.
4.Install the Floor Spring:
Carefully place the floor spring into the anchor sleeves on the floor. Make sure it's level and aligned with the door's pivot point. Secure the floor spring unit to the anchor sleeves using the provided screws or bolts. Tighten them securely but avoid over-tightening, which could affect the spring's operation.
5.Adjustment and Testing:
Depending on the floor spring model, there might be adjustment screws for controlling closing and latching speeds. Consult the manufacturer's instructions for details on how to adjust these settings.If the floor spring requires hydraulic fluid, follow the manufacturer's guidelines for filling it to the recommended level.
6.Test the Door:
Open and close the door several times to ensure smooth and controlled movement. Verify that the door closes securely and latches properly.
7. Install Cover Plate (if applicable):
If your floor spring comes with a cover plate, follow the manufacturer's instructions to attach it over the spring mechanism for a more polished appearance.
Double-check all the screws, bolts, and connections to ensure everything is securely fastened.Confirm that the door opens and closes smoothly without any issues.
Remember that specific installation steps can vary depending on the manufacturer and model of the floor spring. It's crucial to consult the installation instructions provided by the manufacturer to ensure accurate and safe installation. If you're unsure or uncomfortable with any step of the installation process, it's advisable to seek professional assistance to ensure that the floor spring is installed correctly and functions as intended Subscribing to our JUSTOR ground springs can have supporting pre-sales and after-sales facilities And with video professional guidance 24 hours at your service.
How to adjust the control zones in a floor spring?
Adjusting the control zones in a floor spring involves modifying the closing and latching speeds of the door, as well as other potential settings. The process may vary depending on the manufacturer and model of the floor spring. Here's a general guide on how to adjust the control zones in a floor spring:
Note: Always consult the manufacturer's installation and adjustment manual for your specific floor spring model, as the terminology and procedures can differ.
Tools You'll Need:
①Screwdrivers (flathead and Phillips)
②Allen wrenches (if applicable)
③Measuring tape (for precise adjustments)
④Protective eyewear and gloves (recommended)
⑤Adjustment template (provided with some floor springs)
Adjusting the Control Zones:
1.Closing Speed Adjustment:
Locate the closing speed adjustment valve, screw, or knob on the floor spring. This might be labeled or marked. Using the appropriate tool (screwdriver or Allen wrench), make adjustments by turning the screw or knob. Generally, turning it clockwise decrease the closing speed, and counterclockwise increase it. Test the door after each adjustment to ensure it closes smoothly and securely.
2.Latching Speed Adjustment:
Similar to the closing speed adjustment, locate the latching speed adjustment valve, screw, or knob. Use the tool to turn the screw or knob clockwise to increase the latching speed, and counterclockwise to decrease it.Test the door to confirm that it latches properly and securely.
3.Optional: Hold Open Adjustment (if applicable):
Some floor springs have a hold-open feature that keeps the door open at a specific angle. If your floor spring has this feature, locate the hold-open adjustment and follow the manufacturer's instructions to adjust it.
4.Test and Fine-Tune:
After making adjustments, thoroughly test the door to make sure it behaves as intended. Adjustments might need to be fine-tuned to achieve the desired performance.
