BLOC-O-LIFT Locking Gas Spring

Variable Adjustment Option with Elastic Locking

In its standard version, the BLOC-O-LIFT is an elastic locking gas spring that not only allows you to adjust furniture and flaps conveniently and easily, but also to position them variably, where they will be held safely.

Its preferred use is in the backrest adjustment of swivel chairs, where a slight bounce is desirable from an ergonomic point of view.

Function

The locking function is made possible by a special piston / valve system which creates a leak-proof separation between the two pressure chambers in the spring. With the valve open, BLOC-O-LIFT will provide force assist, ensuring user-friendly motion sequences due to its predefined damping characteristics. When the valve is closed, the gas spring will lock with a slight bounce in the desired position.

The standard BLOC-O-LIFT is filled with gas and should be installed with the piston rod pointing down.

Gas Spring with Rigid Locking in the Direction of Tension or Compression

BLOC-O-LIFT springs from STABILUS even hold larger loads safely and reliably in place.

Function

Unlike the purely gas-filled, elastic locking standard BLOC-O-LIFT spring, the entire stroke is filled with oil in this version, allowing rigid locking. A special separating piston separates the gas chamber from the oil chamber. Depending on the type, this will provide different locking forces in the extension direction (tensile lock) or in the compression direction (compression lock).

As an added advantage, the gas spring can be installed in any position.

Locking Gas Spring with Height Adjustment and Even Force Distribution over the Entire Stroke

The BLOC-O-LIFT-T gas spring from Stabilus is used primarily for the convenient adjustment of table heights.

Function

The very flat characteristic curve provides virtually even force assist over the entire stroke. This makes it easy to adjust the table top, regardless of its weight, without the table losing stability or strength.

This gas spring can be installed in any orientation. The lock can be released optionally by hand or foot lever allowing the table height to be adjusted fast and easily.

SOFT-O-TOUCH
Cable release

This program offers complete release systems with an attractive design. Five different ergonomic push-buttons and levers with axial or lateral Bowden cable configurations as well as two different release heads give you even more flexibility in your design and in positioning the gas spring in your application.

Further BLOC-O-LIFT release systems

In the standard version, the BLOC-O-LIFT uses a sliding valve with an release stroke of 2.5 mm. A seat valve is available for short stroke of 1 mm and very easy operation.

Indirect Bowden cable release:

A Bowden cable release is used when the release mechanism cannot be installed directly on the gas spring. This system consists of a release head, a Bowden cable with optional lengths, and the release unit.

Direct release:

For applications with direct release on the gas spring, there are release heads with diefferent lever variants.

We will gladly help you select the right system.

Application Examples

• Backrest and armrest adjustment in swivel chairs
• Table height adjustment
• Head and foot panel adjustment in treatment tables and beds

Gas Spring with Rigid Locking for Vertical Installations

A cost efficient alternative in rigid locking gas springs can be achieved if BLOC-O-LIFT from STABILUS is mounted almost vertically.

Function

Since oil cannot be compressed, gravity will ensure the usual safe holding force. Consequently, the additional piston as a separating element between gas and oil will not be necessary.

In this version, the entire working stroke of the piston is located in the oil layer, allowing the required rigid locking of the BLOC-O-LIFT in any position.

For locking in the compression direction, the BLOC-O-LIFT must be installed with the piston rod pointing up. In the rare cases where locking in the extension direction is desired, a BLOC-O-LIFT version with the piston rod pointing down should be mounted.

The Locking Gas Spring with Overload Protection

In addition to variable locking, this BLOC-O-LIFT variant from Stabilus is equipped with a so-called override function, which protects components from overload and significantly facilitates handling.

Function

In the tension override function, the gas spring will lock rigidly in the compressed state. If too high a tensile force is applied to the piston rod, an overload valve in the piston will open automatically and release the lock. The gas spring extends, thereby protecting the application from damage, e.g., from hitting the floor.

This variant is preferred in chairs and beds or treatment tables and beds. Head and foot panels can be adjusted without operating a separate actuation mechanism.

In the compression override function, the gas spring will lock in the extended state. In this version, too, an overload valve will open as soon as the load on the gas spring extends a defined limit. The lock will be released, the piston rod retracted slowly, protecting the application from overload. Proven protection that is often used in the height and tilt adjustment of desk and table tops.

Gas Spring without Locking in Extension Direction

Customized for safe and comfortable handling, mobile bedside tables for hospital and nursing home beds benefit from a gas spring with infinitely variable height adjustment – BLOC-O-LIFT OBT (Over Bed Table).

Function

It will lock rigidly in any desired position; it can be pulled out immediately without actuation if the situation so requires.

In an emergency, the table top can be moved up and away using light pressure from below. The actuation lever is only required for lowering the table.

Usually, the OBT function of Stabilus gas springs is used in vertical installations.

Combined Functionality for Special Applications

With KOMBI-LIFT, a lid can be closed from two selectable positions.

Tailgates of high vehicles (vans) are protected from slamming into the garage ceiling or door. This will also allow shorter people to limit the opening angle of the trunk, facilitating the use of their car.

Function

The KOMBI-LIFT from Stabilus combines the advantages of locking and non-locking gas springs. With a lever on the piston rod, a defined partial range of the stroke can be locked during extension.

For this purpose, the KOMBI-LIFT is equipped with a special groove in the pressure tube. When the valve is open, the lid will open across the entire opening angle to the end position.

With the valve closed, the piston rod can only move within a range that corresponds to the opening angle specified in the groove. The functional areas can be arranged in any form over the entire stroke.

The lid will close and, consequently, the gas spring will compress without actuation.
