Description of the invention (1) The present invention relates to a foldable cover for a box-shaped appliance, wherein the wings of a plurality of linked foldable covers are guided in a U-shaped guide rail, and the balance mechanism ( counterweight) on the drive of the foldable lid to prevent the lid from opening and closing unexpectedly. The balancing mechanism consists of a single continuous rope, the free end of which is attached to the flap of the foldable lid and is guided by at least two deflectors according to the principle of a pulley. A spring is attached between the deflection member and the shaft on the inner side of the device through the main support member. German patent 91 03 919.3 shows a folding lid of the above-mentioned type. This type of cover minimizes the effort required to maintain tension when the spring is used to gradually lose tension. In addition, a driving system is provided that does not require a moving system that gradually slows down from the diaphragm to maintain the tension of the torsion spring. Inserting the end cap into the cavity of the guide tube and making a part of the area protrude from this cavity can achieve the above purpose. The tooth-shaped protruding members are evenly distributed on the protruding portions of the peripheral edge from these partial areas located on the outer peripheral edge of the guide tube. These protruding parts engage into corresponding grooves on the inner periphery of the central bore of the cog and extend beyond the axial length of the cog. The end cap is located on the rotating bearing of the shaft and is detachably connected to the cog by a mechanical moving mechanism. When the spring is stretched, by turning the end cap of the guide tube and pulling the outer spring end, the appropriate torque required for the balance weight of the folding lid can be adjusted. This foldable lid system meets its practical needs, however, since the guide rail is attached to the side wall, the width of the appliance is narrowed. It also reduces the space on the appliance height. Another known technology of the folding cover is disclosed in the German patent No. t paper size applicable to the Chinese National Standard (CNS) / Vi specification (210 x 297 mm) ''

Invention Description (2) 2 9 6 18 802. 6 Here, a stacked cover having a counterweight is disclosed, which technically has a low manufacturing cost. The counterweight is a single continuous rope, the free end of which is connected to the flap of the foldable lid, and is guided across the two deflectors according to the principle of a pulley. A compression spring is disposed between the deflectors, and receives doubled power in an elastic manner with respect to the force applied to the rope. This can be achieved by a configuration consisting of a rope, a deflector, and a pressure spring guided on the upper edge of the foldable lid. Understandably, the advantage is that the foldable lid is not rolled up, but is guided behind the back wall of the appliance. A further advantage of this system is a guide groove sunk into the wall of the appliance, which guide groove allows the appliance to have a maximum use width. However, when used with very tall or very narrow appliances, the system of folding lids presents physical limitations. Due to the restrictions on the height and width of the pulley mechanism and the spring channel, the best use of the folding lid cannot be achieved. The object of the present invention is to improve the disadvantages of the conventional description. The present invention provides an auxiliary mechanism of a folding lid system, which can cover the entire surface of a conventional box-shaped appliance in a cheap and simple manner. According to the present invention, a reed drum is installed on the free end of a shaft for receiving The rope is released, and a torsion spring is arranged between the coil drums. The free end of the torsion spring is connected to the reed drum, and the other end is fixed to the rotating shaft, and there is at least one spacer between the torsion spring and the rotating shaft. Understandably, with this configuration, almost all the height of the box-shaped appliances can be effectively used = and there is no restriction on the height and width of the box-shaped appliances. This paper is in compliance with the national standard (CNS) A4 specification ( 210 497 mm) (谙 Please read the business matters on the back before filling this page)

Description of Invention (3). By using the spacer member according to the present invention, it is possible to prevent the torsion spring from sagging under a state where no load is applied, and therefore, no noise is generated when the auxiliary mechanism is rotated. A further advantage of the present invention is that the spacer ring member according to the present invention prevents the torsion torsion spring from contacting the protection tube. This prevents noise during rotation and prevents erosion of the material on the inner wall of the protective tube. The spacer member according to the present invention must have an outer diameter smaller than the inner diameter of the torsion spring. In addition, the torsion spring is surrounded by the protective tube and the free end is connected to the coil drum 'is also an advantage of the present invention. In order to ensure easy and simple use of the folding lid, the size of the torsion spring must be designed so that the force required to operate the folding lid does not exceed 5 0 N. In this case, the torsion spring balances the weight towards the front and rear sides. A further advantage is that the auxiliary mechanism of the present invention can be simply installed and can be operated and maintained at low cost. By doing so, the user can obtain double economic benefits. In other advantages of the invention, a free end of the torsion spring is connected to the protective tube. Due to the progressive configuration of the auxiliary mechanism, when the minimum tension point of the rope is reached, it can be ensured that the rope can still be guided and supported on the coil drum. The present invention will be further explained with reference to the drawings as follows. Figure 1 shows the front view of the foldable cover, which contains the actuating mechanism. 0 Figure 2 shows the sectional view of the auxiliary mechanism.
