Field of the Invention This invention relates to a bent arched support assembly for use in a curved and/or tempered compartment of a glass panel, the support assembly comprising a plurality of link bodies And a control link mechanism disposed between the link bodies, the link bodies are coupled to each other by an engagement shaft that controls the arch of the support assembly to be curved in a constant curvature. [Prior Art] This type of support assembly is known from the applicant's publication EP- 1 3 8 5 795. This support set has proven to be very useful. SUMMARY OF THE INVENTION It is an object of the present invention to further improve the support assembly so that a long support assembly can be precisely bent into an arch having a constant radius of curvature by a simple and inexpensive actuator, without becoming disadvantageous. The link clearance of the factors, or even the link clearance can be used to provide a very slight intentional curvature error. This object is achieved by the feature construction presented in the first item of the appended patent application. The preferred embodiment of the invention is presented in an accessory. [Embodiment] Fig. 1 shows a support assembly 4 of a curved conveyor belt on the left side of the upright line 6 and a support assembly 5 on the left side of the tempering conveyor belt. The support assemblies 4, 5 are mechanically joined to each other at the joint 6a, whereby the support assemblies -4-200906745 4 and 5 can be disengaged from each other as desired. The joint 6a between the assemblies 4 and 5 remains stationary, whereby the upstream end of the support assembly 4 and the downstream end of the support assembly 5 can be lifted and lowered for the support assembly to achieve the desired Curvature and straight construction. The support assemblies 4 and 5 enable the conveyor belt rollers to support the curved conveyor belt and the tempering conveyor belt. The support assemblies 4 and 5 include a link body 9 disposed on both sides of the conveyor belt (i.e., at both ends of the roller), with bearings for the belt rollers. On the other hand, each link body 9 is connected to each other by the link mechanism shown in Figs. 2 and 3, and when the support assembly is bent into an arch, the link mechanism forces each link body 9 to pivot relative to each other to be equal. degree. The link mechanism incorporating each link body 9 includes three engagement arms 1, 2, 3 that couple the three link bodies to each other each time such that the link bodies are forced to pivot to each other to an extent, Thereby, the entire support assembly is bent into an arch having a constant radius of curvature. The configuration for engaging the joints of the arms 1, 2, 3 is described in more detail in the patent EP- 1 3 8 5795 (B1) and is therefore not discussed in this specification. Figure 1 shows a servo motor 10 which is operated by a clutch to operate a ball screw 10a, a ball screw that pushes and/or pivots the lever system 11. A support assembly constructed by the link body 9 is disposed on the lever system. The radius of curvature R1 of the support assembly 4 can be adjusted by the servo motor 10. The mechanism for bending the support assembly 5 of the tempering conveyor belt into a dome includes a servo motor SM1 and a ball screw 12a operated by the servo motor SM1. The ball screw 12a passes through the intermediate piece of the arm 12b to arch the bridge formed by the plurality of link bodies 9, and the entire conveyor belt is thereby carried by the support assembly 5. Each arm 12b engages the conveyor belt 5 and is a short distance from the end of the conveyor belt 5. The second servo motor SM2 operates the ball screw 17 using the 200906745 herringbone gear 16, and the respective ball screws 17 are engaged at the opposite outer ends of the support assembly 5. The operation of the servo motors S Μ 1 and S M2 is synchronized by the electric gear box, enabling the support assembly 5 to be bent into an arch having the same radius of curvature. Since the different sections of the support assembly 5 are arched using different servo motors SM1 and SM2, the inaccuracy of the curvature of the support assembly and the conveyor belt it carries can be eliminated. The gap caused by the wear of the rod is caused. In particular, the curvature of the middle portion and the end can remain the same. In the preferred embodiment now described, the first section of the arched support assembly 5 is in the intermediate portion of the support assembly and the second section is in the end portion of the support assembly. The support assembly 5 in question is preferably a support assembly of a tempering conveyor belt. The support assembly of the tempering conveyor belt is generally longer than the support assembly 4 of the curved conveyor belt. In a preferred embodiment of the invention, the support assembly 4 of the curved conveyor belt is disposed prior to the support assembly 5 of the tempering conveyor belt. The support assembly 4 of the curved conveyor belt has its own separate servo drive 10, 10a, 1 1 'for arching the support assembly 4 to a constant radius of curvature R 1 . The downstream end of the support assembly 4 remains stationary and its upstream end is lifted by the servo 10. In this example, 'the gap of the link mechanism can also be controlled' so that the support assembly 4 can always be bent into an arch shape having a desired radius of curvature.
