Title: Opaque electronic opening device with one opening and closing direction
Inventor: YOON EUN KI
IPC: E05B47/02
Filed: 2019-08-26
Abstract: Disclosed is an opaque electronic opening device having one opening and closing direction. Provided is an opening device based on a state in which a protrusion unit provided on a door sill always protrudes upward using a solenoid. A door has a structure in which when a door handle is turned, a current is cut off to the solenoid of the protrusion unit of the corresponding door handle, and the protrusion unit is lowered to open the door by allowing the door handle to be pulled in a direction in which the door handle is turned. Since the above-mentioned solenoid has a structure in which power is automatically cut off in an emergency such as a power outage, fire or the like and the protrusion unit is lowered, in unforeseen circumstances, it is difficult for people inside to be detained. In addition, since the protrusion unit protrudes using the solenoid, even when the protrusion unit is not lowered due to a malfunction of a power system, a user can easily step on the protrusion unit with a foot and lower the protrusion unit down.

Title: the seismic isolation function double floor adding and subtract the seismic isolation driving part
Inventor: JANG SEONG CHEOL
IPC: E04F15/024
Filed: 2019-09-02
Abstract: There are technologies for the seismic isolation of a whole double floor under development and one of them is the seismic isolation double floor technology which is currently applied partly. Up until now, the general double floor having a seismic isolation driving unit plays a key role to perform the seismic isolation function by a seismic isolation driving unit and a pillar and to sustain the load mounted. For the characteristics of the double floor, the mounted load constantly increases as the double floor is used more and more. In most cases, the expected mounted load in the design and the mounted load required for construction are changed and mostly increased. The mounted load during operation is changed to be increased from the designed load, and frequently, there is heavy equipment placed on a specific part of the double floor, so there is often such a case where the mounted load of the double floor needs to be supplemented partly. However, there is the only structure which installs a single seismic isolation driving unit on the pillar, so it is hard to flexibly deal with the increased mounted load. The present invention includes a first horizontal frame and a second horizontal frame, and inserts a seismic isolation driving unit between the two to be engaged, thereby flexibly responding to changes in the mounted load.
