Aseismatic support platform
The present invention relates to an aseismatic support unit, and more particularly to an aseismatic support unit capable of being easily and fitly in-situ assembled to become an aseismatic system. The aseismatic support unit is mounted between a base and a loaded article, comprising a lower support member, an upper support member and a plurality of aseismatic units mounted therebetween. Each of the aseismatic units includes a lower carry member having an upward carry surface, an upper carry member having a downward carry surface and a support roller mounted therebetween. When an earthquake happens, shakes are transmitted from the base. Then, the aseismatic support unit of the present invention diminishes the extent of the shakes of the load article placed over the upper support member and thus prevent the loaded article from overturn and damage as a result of the earthquake.

2. Description of Related Art
Earthquake disasters occur frequently around the world, causing tremendous personal injuries and death as well as serious loss of property that cannot be recovered. Nowadays, the industrial and commercial communities rely heavily on exchange of a great deal of data to perform various industrial and commercial activities either by computer networks or common telecommunication exchanges. In addition, the infrastructure system for supplying water, electricity, gas and transportation to meet the basic needs for the society functions also relies heavily on data by means of the computer networks or the common telecommunication exchanges to maintain their operations. Thus, an earthquake causes not only inconveniences to our lives as a result of damages to civil constructions such as buildings and bridges, but also abruptly ceases the activities of the whole society as a result of damages to the computer networks or the common telecommunication exchanges. Hence, developments of various aseismatic systems have gradually attracted the attention of responsible personnel. Industry has kept investing enormous amounts of capital and human resources in research in the hope of reducing damage to equipment, facilities etc, such as computer network servers, telecommunication exchanges, buildings or bridges necessary for maintaining the basic operations of the society and so minimize the influences of the earthquake disasters on our lives.
Aseismatic systems currently available from the market are formed independently of the equipment such as the aforesaid computer network server or the telecommunication exchange to be protected, instead of being integral with the equipment being protected. Hence, the aseismatic systems are generally assembled on the construction site where the equipment to be protected is mounted, for example, the telecommunication exchange room or the computer room. However, any of these places (e.g., the computer room) is limited in space due to being full of other machines (servers). Thus, difficulty of in-situ installation of the aseismatic system increases, and also, time for such installation is prolonged. Furthermore, because the aseismatic systems currently available are excessively large, the in-situ installation will generally have drawbacks in the normal operation of the equipment to be protected; for example, the equipment needs to be powered off for wire reconnections. Therefore, the clients will worry about these drawbacks and hesitate to install the aseismatic system. Consequently, the main target of the researches for the aseismatic systems in the industry is to reduce the size of the presently existing aseismatic systems and simplify the process for installing the aseismatic system.
A construction unit 10 for forming a conventional aseismatic system is shown in
When the conventional aseismatic system 17 and the equipment being protected by the system 17 shake as a result of an earthquake, the equipment (computer network server or telecommunication exchange) to be protected and the two construction units 10 of the aseismatic system 17 will swing back and forth due to the inertial actions. At the same time, the support roller 16 of the construction unit 10 rolls back and forth between the downward carry surface 141 and the upward carry surface 151 to gradually retard the swing of the equipment (computer network server or telecommunication exchange) being protected. However, as mentioned in the above, because both the downward carry surface 141 V-shaped in section, facing downward, and the upward carry surface 151 V-shaped in section, as provided in the construction unit 10 are irregular, the support roller 16 keeps hitting against the irregular downward carry surface 141 V-shaped in section, facing downward, or the irregular upward carry surface 151 V-shaped in section when the support roller 16 rolls back and forth between the downward carry surface 141 and the upward carry surface 151, resulting in an obstructed rolling of the support roller 16 between the downward carry surface 141 and the upward carry surface 151. In addition, the strokes will bring about very noisy sound, and also, chances of overturning the equipment being protected increase.
Moreover, the construction unit 10 of the conventional aseismatic system 17 relies merely on the flanges 142 disposed on the edges of the downward carry surface 141 and the flanges 152 disposed on the edges of the upward carry surface 151 to define the rolling range of the support roller 16. Thus, when the support roller 16 rolls rapidly (when a major earthquake happens), the support roller 16 of the conventional aseismatic system 17 is very likely to roll out of the predetermined rolling range and finally rests on somewhere between the flanges 142 and 152 in an inclined manner. Then, the aseismatic system 17 will not operate normally and the equipment mounted above and supposedly being protected by the aseismatic system 17 will overturn.
In addition, as stated in the above, the conventional aseismatic system 17 is composed of two construction units 10 and the links 18 by welding in the factory in advance. Thus, the assembled conventional aseismatic system 17 will be noticeably oversized and heavy to a certain extent. As a result, the conventional aseismatic system 17 has difficulties in transportation thereof and complex installing procedures so that the time for the installation will be prolonged. Furthermore, because the peripheries of the conventional aseismatic system 17 are all welded, the wires for connecting the equipment to be protected to external devices must be pulled out for proceeding with the installation of the aseismatic system 17 and reconnected for resuming the power after the installation of the conventional aseismatic system 17 is completed. Therefore, services such as computer network services will be interrupted due to the installation of the conventional aseismatic system 17, causing an inconvenience to the clients and the public.
Accordingly, there is a dire need for the industry to have an aseismatic system which can be easily and fitly in-situ assembled for equipment to be protected without discontinuing the operation of the equipment.
SUMMARY OF THE INVENTIONAn object of the present invention is to provide an aseismatic support unit so as to be easily and fitly in-situ assembled for an equipment to be protected without discontinuing the operation of the equipment.
Another object of the present invention is to provide an aseismatic support unit so as to reduce the possibility of toppling over equipment to be protected and increase the quakeproof function of the aseismatic system.
To attain the aforesaid object, an aseismatic support unit according to the present invention is mounted between a base and a loaded article, comprising a lower support member, an upper support member and a plurality of aseismatic units mounted between the lower support member and the upper support member.
