Definitions
- the present invention relates to a device intended to compensate for the mass of an object driven in a vertical, upward or descending.
- the type of device according to the invention is intended to compensate, during the opening and closing, doors with vertical lift, such as for example doors garage.
- the doors are balanced, or compensated, by different devices, such as counterweights for example.
- These devices employ for example a torsion spring associated with a drum on which the door actuation cable is wound.
- the axial displacement of the nut compresses the spring, thus creating a return torque on the screw and therefore on the motor shaft, torque to balance the door.
- this balancing torque increases in the closing phase and decreases in the phase opening.
- this type of device cannot balance doors whose mass does not vary little or no during lifting, such as overhead or stacking doors sections.
- devices are also known to compensate for the mass of an object during a vertical up or down movement due to rotation a shaft having two threads in opposite directions and comprising a spring capable of be compressed or decompressed between two movable stops in translation during rotation of the shaft, each stop consisting of a nut immobilized in rotation.
- the present invention provides a device capable of balancing the doors with vertical lift whose mass does not vary or very little during the opening and closing, providing a constant compensation effort with a minimum of parts.
- the device for compensating for the mass of an object during a upward or downward vertical movement due to the rotation of a shaft having two threads comprising a spring capable of being compressed or decompressed between two movable stops in translation during the rotation of the shaft, each stop consisting of a nut immobilized in rotation is characterized in that the threads made on the shaft have a pitch different for each of the two nuts and have the same meaning.
- the spring is engaged on the shaft.
- the device according to the invention is associated with means actuators that include a drum.
- the motor means are provided for actuating the shaft rotation.
- the device according to the invention is applied to the lifting door with constant or very little variable mass:
- the horizontal direction is defined by the ground S, the vertical direction being substantially perpendicular to the direction horizontal.
- Figure 1 shows, in schematic side view, a first type of vertical lift door on which the device according to the invention, more particularly called tilting door.
- the assembly consists of two vertical rails 1, of known type and located in the ground S (only the vertical rail 1a being visible in FIG. 1).
- Each vertical rail 1 is associated with a horizontal rail 2, arranged at the free end of it, opposite the ground S.
- a apron 3 slides in the rails 1, 2 to take different positions 3a, 3b, 3c between a closed position where the deck 3 is parallel to the rails vertical 1 and an open position where the deck 3 is parallel to the rails horizontal 2.
- the opening of the overhead door is done by the rise of the apron 3 in the direction and direction of the arrow f1, the closing being effected by means of the lowering of the deck 3 in the direction and direction of the arrow f2.
- Figure 2 is a schematic side view of a second type of door to which the device according to the invention can be applied.
- This type of door comprises a flexible articulated apron 4 or rigid mounted in a known manner on a pair of vertical rails 1 fixed on the ground S serving as guide means.
- the articulated apron 4 of classical architecture, comprises sections 4a connected together by pivot links 4b.
- Actuating means allow opening the door by driving the hinged apron 4 upwards (direction of arrow f1).
- the different sections 4a fold in accordion on top of each other.
- Closing is carried out by lowering (direction of arrow f2) the sections 4a of the articulated deck 4.
- FIG 3 is a perspective view of the swing door 3 Figure 1, showing the layout of the device 5 according to the invention.
- the device according to the invention 5 is arranged at the level of the upper part a vertical rail (rail 1b in the exemplary embodiment of FIG. 3), substantially at the junction of rails 1b and 2b.
- a second device 5 can be arranged symmetrically at the junction of rails 1a and 2a.
- Actuating means 6, consisting for example of a strap 7 or a cable winding on a drum 8 or any other similar means, are connected, at one end, to the device 5, and at the other end, to the base apron 3.
- actuating means 6 can either be coupled to a motor, either operate manually.
- Figure 4 shows, in schematic side view, the detail of the device 5 applied to a particular embodiment where the means actuation 6 include a strap 7 adapted to be wound on a drum 8 when the door is opened.
- the device 5 comprises a shaft 9, of substantially horizontal axis X, coupled in a known manner at one of its ends to the drum 8, and to the other end either to motor means or to support means such as a bearing, both known and not shown.
- the shaft 9 has, on a first part, a first thread 10 on which is screwed a first nut 11, of generally known shape and having a bearing face 11a, perpendicular to the shaft 9 and turned towards the drum 8.
- the shaft 9 has, on a second part, a second thread 12 onto which is screwed a second nut 13, of generally known shape and having a bearing face 13a, also perpendicular to the shaft 9 and arranged opposite the bearing face 11a of the nut 11.
- the first thread 10, on which the first nut 11 is screwed is made at the end opposite to that where the drum 8 is located, while the second thread 12, on which the second nut 13 is screwed, is adjacent drum 8.
- the nuts 11, 13 are immobilized in rotation by all types of process known but are free in translation, and during the rotation of the shaft 9, the nuts 11, 13 move in translation relative to said shaft 9.
- Threads 10 and 12 are the same direction but not different, the pitch of the second thread 12 being weaker than that of the first thread 10.
- the spring 14 is therefore in abutment against the bearing faces 11a and 13a nuts 11 and 13.
- the compression of the spring 14 induces a torque on the shaft 9, by through the nuts 11, 13 against which the spring 14 is in support.
- this induced torque increases (compression of spring 14) or decreases (decompression of spring 14) and thus, either facilitates or thwarts said rotation.
- the spring 14 is generally compressed or decompressed according to the direction of movement of the nuts 11, 13, and therefore according to the direction of rotation of the shaft 9.
- the first nut 11 compresses the spring 14, while the second nut 13 tends to slightly decompress it in order to limit the amplitude of the variation in induced torque on the shaft 9.
- the first nut 11 decompresses the spring 14, while the second nut 13 tends to slightly compress it, always in order to limit the amplitude of the variation of the torque induced on the shaft 9.
- the rotation of the shaft 9 causes the unwinding of the strap 7 of the drum 8 (position shown in solid lines).
- the first nut 11 tends to compress the spring 14 against the face 13a of the second nut 13.
- the difference in travel of the nuts 11 and 13 generally causes a compression of the spring 14, which thus stores energy capable to be returned to tree 9 during the opening phase.
- the nut 13 by slightly decompressing the spring 14, decreases the amplitude of the variation of the torque on the shaft 9 during compression of spring 14.
- the rotation of the shaft 9 causes the winding of the strap 7 around the drum 8 (to reach the position shown in broken lines).
- the nuts both move in the direction of arrow f4.
- the first nut 11, moving, causes the decompression of the spring 14, slightly compressed by the second nut 13.
- the opening of the door is thereby facilitated. If this opening is performed manually, the effort required to lift the deck 3 is less important.
- the aid provided by the device 5 reduces the engine power.
- the device 5 is adjustable, and this on several levels.
- the intrinsic characteristics of the elastic element directly influence the compression and therefore the amount of energy transmitted to the tree 9.
- the device is therefore adaptable to all types of door with vertical lift, of constant or little varying mass, regardless of the mass of the apron.
