Abstract
Free ends of cables (6,6') of the counterweight system are attached to coiling drums (31,32), between which is a torsion spring (4). One free end is linked to one of the drums and the other free end is linked to the spindle (7) carrying the drums. Between the spindle and the torsion spring is at least one spacer member (9). Preferably the outside diameter of the spacer member is smaller than the inside diameter of the torsion spring. A protective tube (5) can be fixed over the torsion spring and the free ends of the coiling drums.
Description
Technical field
The present invention relates to a kind of rolling door that is used for box-shaped furniture dress thing mouth, wherein a plurality of mutually hinged moulding louvre blades are guided in the U-shaped profiled guide rail of side, and, the counterweight of in the rolling door drive unit, packing into, it prevents that rolling door from closing unexpectedly and opening, counterweight is a cable wire that monolithic is continuous, this cable wire free end is fixed on the moulding louvre blade and by at least two transfers by the burton principle and guides, between transfer, fix a spring, and between box-shaped furniture inwall, fix an axle by main support.
Background technology
In German utility model 9103919.3, introduced a kind of such rolling door.This rolling door drops to minimum level being used for needed the expending of tensioning spring, because along with the more and more springs of access times lose its pretightning force.A kind of drive system is provided in addition, wherein, for the tensioning torsionspring does not need to dismantle kinematic system from circle, the side wall of rolling door.This reaches like this, that is, the end plug in the catheter diameter inboard of packing into is from the protruding part of internal diameter.Protrude from the excircle that this part surpasses conduit along the equally distributed dentation of circumference.These projections are inserted in the corresponding groove that is located at the gear axial length extension of gear center hole inner periphery upper edge.End plug can be rotated to support on axle and upward and with gear detachably is connected by means of mechanical fastening system.For preloading spring,, adjust needed reseting torque at rolling door weight by the end plug of rotary guide pipe and the clip of spring outer end.
Though this rolling door system satisfies its instructions for use by the mode of generally acknowledging actually, what should point out emphatically is that the guide rail that employing is installed on sidewall has lost the span width in cabinet.
Because selected structure is causing the position loss aspect the clear height in cabinet.
In German utility model 29618802.6, introduced another kind of this type of rolling door.
Here rolling door has used counterweight, and it can be also uncomplicated technically and makes economically.This reaches like this, that is, counterweight is the continuous cable wire of monolithic, and it is with fixing the sagging of lotus state of its free end, so can not produce noise fully when compensation mechanism rotates.
Another conclusive advantage is that by using by spacing part of the present invention, the torsionspring that strand is changeed under load does not contact with protection tube.Thereby avoid making a noise when rotated and the fret wear on the protection tube inwall.Therefore, by spacing part of the present invention an external diameter littler than the internal diameter of torsionspring must be arranged.
The best protected circumference of cannon bone of torsionspring around, the protection tube big envelope is on the free end of reel.For guaranteeing that the user is convenient and unhinderedly operate Rolling door cabinet, the size of torsionspring should be designed to, and this rolling door system just should be able to move with maximum 50N power.Therefore, torsionspring can compensate produced forward and gravity backward.
Another conclusive advantage of the present invention is that this compensation mechanism that is easy to assemble is worked non-maintainingly and can be produced economically.Therefore double economic interests are provided for the user.
In another favourable application, torsionspring is hinged on the protection tube with an one free end.
Adopt the favourable structure of selected compensation mechanism, guarantee to reach when cable wire the place of minimum tension, the cable wire support slides on the reel that batches or emit cable wire.
Description of drawings
Use schematic view illustrating the present invention below, wherein:
The rolling door front elevation drawing of the motion that Fig. 1 band schematically illustrates; And
Fig. 2 compensation mechanism sectional view.
The specific embodiment
Fig. 1 represents the rolling door in the box furniture 2, wherein is shaped on the guide groove 211,221 of moulding louvre blade side in sidewall 21,22.Be provided with protection tube 5 above the moulding louvre blade, it rests on the reel 31,32 at its free end.At the visible torsionspring 4 in protection tube 5 the insides.In this favourable form of implementation, cable wire 6 is fixed on the reel 31 and is parallel to the further traverses fixed part 75 of this bar after turning to 90 ° on the cable wire support 70 that is fixed on the louvre blade bar 11 and extends, extend to cable wire support 71 always, turn to 90 ° and be fixed on the reel 32 there.In this form of implementation, fixture 75 plays the straight-through safety device of cable wire 6.The characteristics of louvre blade bar 11 are the central authorities at rolling door, and rolling door is in the position of cable tension minimum when half-open in central authorities.By the different handle type line plate of operating weight, latch fitting etc., this position can be different.In another kind of form of implementation, cable wire 6 is fixed on the reel 31, cable wire 6 ' be fixed on the reel 32.Cable wire 6 is by cable wire support 70 and cable wire 6 ' lead to the central authorities of moulding louvre blade 11 by cable wire support 71, and can merge connection at two the cable wire ends in this position at fixture 75 places.
Fig. 2 represents by by compensation mechanism sectional view of the present invention.As can be seen, axle 7 inserts in main support 90,91 and is fixed in the main support at two free end.At the visible reel 31,32 of the free end of axle 7, torsionspring 4 is arranged between reel.Torsionspring 4 is connected with reel 31 at its free end 81, and is fixed on the axle 7 by its another free end 80.
