The invention relates to a device for compensating the weight of a gate
mobile and in particular a portal of
a single panel tilting to the ceiling.
The coil springs serve in a known manner to compensate
the weight of the displaced gate panel, in such a way that
that his movements, as far as possible over the whole par-
course between closing and opening positions,
to be done with weak forces,
During the movement of the gate panel between the
the opening position and the closed position, the coil springs are only lengthened over a relatively
weak and they are strongly prestressed. If such a res-
pulling force breaks under its maximum elongation load, the sudden release of the force accumulated in the spring 1.5 causes an impact, with considerable energies,

spring. This entails a danger of significant damage.
Damage to the construction of the door may result in deformities of such a magnitude that

its support is no longer possible. On the contrary
parts supporting the frame, respectively the pan-
door can also be damaged and required.
important costs for their refurbishment.
In order to be able to coat a door panel (later) with a covering, soundproofing or insulation against heat
and / or decorative applications while keeping the possibility
In addition, with its weight balancing function, smaller additional springs were provided which, passing through the tension coil springs calibrated according to the initial weight of the door panel, were accommodated in the space at
inside the turns of the initial coil springs.
If an outer coil spring breaks, the additional internal coil spring is also overstretched
as will be shown later so that this spring
dull can no longer absorb the charges that are generated and also breaks * A result that the invention aims to obtain is a weight compensation device of a portal of the kind mentioned above, with which the dangers, respectively the possibilities of damage , caused by a spring that breaks as well as by an uncontrolled tearing of the spring from its normal position, or by a too abrupt shock to the door maneuver on the anchoring points are greatly reduced. For this purpose, the object of the invention is such a device, characterized in that at least one of the coil springs is traversed by an assembly formed of an element
ribbon form receiving an ectrémité spring and a éé16-
elongated construction, which is longitudinally longitudinally slidably guided with respect to the sliver and is secured to the other end of the drawbar spring and at least one of the elements that
are the ribbon and the building element present, in parti-
in the area surrounding the upper textremity of the coil spring, a damping zone in the form of a deformable zone in the longitudinal direction of the ribbon and / or
the building element.
By the whole which crosses the spring, and which is constituted
killed by the ribbon and the elongated building element, which is guided so as to slide along the ribbon lengthwise and whose length variation as a result of this sliding corresponds to at least the elongation of the spring
when the door panel is moved from its
up to its closed position, it is first assured that in the event of breakage of the spring, fragments of variable size depending on the break point, can not move away laterally uncontrollably since the whole who crosses them will prevent them. As a result, the danger of damage to objects within their reach, and in particular injuries, is greatly reduced.
people who are close enough.
In addition, the force of deflection as the spring that breaks
exerts on both its chassis anchors and the articula-
which supports the panel door, is diminished by the damping area or even annihilated in a
-3- In this respect, the following particularity should be noted: If, for example, the ends of the springs are
maintained in their anchorage so that they can not escape
per side or cause a spatial shift of their anchorage, the spacing between the ends of the springs, respectively anchors, could never undergo a

spring in normal operation. The element of
truction constituted by the ribbon and the element of construction
guided on it so that it can slide in the direction
Therefore, the longitudinal axis of the longitudinal sliding path would not be subjected to any traction force, so that the damping zone, in the form of a zone of elastic deformation, would not be subjected to any traction force. This, however, would not allow the attenuation of the forces exerted on the stops stopped. In the case of a suspension of the spring as it is supposed the Dréambule known in revendlcation 1l the spring is however
hanging in an entrance opening of the ribbon, articulated itself
even on an articulated support device of the door panel Because of this articulation and the conformation of the ribbon, this ribbon is subjected in case of rupture of the spring, & a force which shifts it in such a way by turning it
around its point of articulation and deforming the material
ribbon relative to the spring suspension of
such as at that moment the length between the point of
the spring on the ribbon and the support point on the
frame is larger than the normal lengthening of the spring.
As a result, the building element within the structure
spell is subject to a change in length that goes beyond
of the sliding course. At the end of the slide
the construction element is therefore subjected to a pulling force under which the damping zone is lengthened
with deformation of the band provided accordingly.
Since the elongation of the deformation zone
requires energy, the force that attacks the ribbon is consumed
in the same proportion. During the movement of
tape upwards, apart from the suspension of the
fate, this work of deformation / and additionally the folding -4-
of the section of ribbon which is outside the suspension
of the spring are destroying energy whose order of magnitude
can be determined with a good approximation by the conformation of the deformation zone. This prevents the breakaway spring from acting with such force on the anchor points - particularly in the hinge area of the door panel suspension - that damage can occur.
produce on the supporting parts of the article constmction
abutment and / or chassis.
The damping zone can be made in a simple manner, preferably by a corrugated profile, a more or less pronounced meandering profile, or a zig-zag profile of the ribbon or
the building element. The importance of deformations
length of the ribbon depends to a large extent on the resistance to deformation and the
spring force to capture.
In order to avoid that the parts of the construction element which are guided against each other with sliding lengthwise, namely the ribbon and the construction element, do not abut, when a normal biasing of the spring between the opening and closing positions of the door, against the inner faces of the coils of the coil springs, the longitudinal guidance is achieved with a weak clearance so that bends towards the turns of the flanges remain inside the hollow space of the spring. For this purpose, it is possible to operate in such a way that the end zones of the ribbon and of the construction element which face each other overlap and surround each other, at least partially, by folds each provided on
their ends with a weak game.
In another preferred embodiment, the element of con-
truction is fixed with the lower end of the tension coil spring on the frame of the gate and the damping zone is in the region of the strip in the attachment opening of which, respectively in one of the openings of hanging from which is hooked
the upper end, folded hook-shaped, of the res-
pulled coil.
In principle, both parts of the building element can have the form of ruan. It is equally thinkable
to make the two pieces in a bar-shaped material
However, care must be taken to ensure that the sliding guide in the longitudinal direction at low clearance is retained so as to prevent the building element from abutting against the turns of the mainspring spring. In an execution
preferential element of construction is made of
round while the other building element is a
independent part or a7p with the suspension tape.
In the case of the double-spring embodiment mentioned at the beginning, comprising an internal coil spring and an outer coil spring A surrounding it, the
according to the invention can also be applied in
passing the building element consisting of the pieces that slide against each other in the sounds of the
length & through the inner space of the inner spring.
By means of the exemplary embodiments shown in the drawings
sin, the invention will be explained in more detail. FIGS. 1 and 2 show a side view partially in section, as well as a side view turned ninety degrees with respect to the preceding one, of an embodiment of the construction element with the anchoring points on the frame and the hinged construction of the gate panel and a spring shown only in its end portions in broken lines; FIG. 3: another execution example on which the

construction are made in one piece.

ribbon-shaped, is used for hanging the end
in the form of a hook 2 of the 3-thread pull spring
As a result, a number of fastening apertures 4 are distributed over the length of the ribbon in order to be able to modify the tensile force of the traction coil spring. The support part 1 g -6- consists, in its opposite part to the spring, in a loop 5
by which it can be articulated on a pivot corresponding to
of the articulated support device of the portal panel.
This pivot of the artioulation device serving as a point of
The hollow is chosen so that during the pivoting of the gate panel it describes a path such that the elongation inflicted on the spring balances the weight of the gate panel set in motion. By its lower end 6 in the form of a hook, the traction spring Soudin 3 is hooked on
a fixed anchoring portion 7 of the frame.
The internal space of the spring, surrounded by the turns of the
spring, is crossed by an element designated in its entirety.

LATIONS. To do this, the lower end 11 of the ribbon-shaped portion 9 is bent at right angles and pierced with a hole through which the rod-shaped construction element 10 passes. The upper end of the The rod-shaped construction element is folded around the ribbon-shaped portion 9 so that it constitutes a loop 12 which surrounds the ribbon-shaped portion. Drilling in the bent section 11 of the ribbon-shaped portion 9 and the loop 12 are dimensioned such that they surround the included portion with a weak clearance. In this way we have a simple way of shaping the sliding guide in the
meaning of the length so that the construction element

parts of the building element. If, therefore, a length sliding path is chosen which is slightly greater than the length elongation in normal operation, the function of the damping zone is nevertheless ensured because the spring which breaks out escapes laterally and will not what therefore, seeks to achieve a greater length of the building element. In all cases the parts of the building element will reach the end of the
sliding course by stopping the loop against ltex-
