Description

The present invention relates to a door lock device for a door lock equipment of uchikake expression that can be locked and unlocked operation from the inside of the door is attached by flipping up toes of the foot without touching the hand.

Following the SARS virus and MERS virus that occurred from 2002 to 2015, the infection spread route of the new coronavirus that occurred in 2020 is "three dense" closed spaces (closed spaces with poor ventilation). Splash infection, which is transmitted by dense places (many people are crowded) and close scenes (conversations and vocalizations are performed within reach when reaching each other), drifts in the indoor air with aerosols for about 3 hours. Infection spreads due to aerosol infection, which continues to have infectious power, or contact infection, which is transmitted by contact with an unspecified number of people such as hanging leather of trains and buses, door knobs, switches of elevators and electrical equipment. Has been confirmed.

Infection prevention measures mentioned above include avoiding crowds and short-distance conversations in daily life, singing loudly in a room where many people gather, and exhaling in close contact. Avoid words and actions, wash your hands frequently with soap and alcohol disinfectant, wear a mask to avoid self-infection, and cough etiquette to prevent droplets from infecting others. It is said that preventing infections and diligently ventilating the room are important factors to improve the effectiveness of infection prevention measures.

However, the ratio of those whose infection route is unknown to the number of newly positive infections found by PCR tests, etc. accounts for 40 to 50%, and the actual situation is that the infection route is not yet known, and antibody vaccines are currently available. Due to the fact that it has not been developed, the new coronavirus is now pandemicly spreading.

The applicant has found that the causes of infection in the above-mentioned persons whose infection route is unknown include public facilities, large-scale commercial facilities, public transportation, schools, hospitals, restaurants, large-scale leisure facilities, etc., which may come into contact with an unspecified number of people. Focusing on the possibility of direct infection that comes into contact with the doorknob and lock device of a lavatory booth in a highway parking facility, etc., these factors should be resolved. A virus that makes it easy to open and close the door and lock it without touching it. It proposes an infection prevention device.

Products that have already been developed to solve the above problems include key holder type "non-contact door openers" and "foot-operated foot pedals" (Non-Patent Document 1), and L-shaped flanges are attached to doors. "Knob hook # 1" (Non-Patent Document 2) and "No-touch knob" (Non-Patent Document 3) for turning a doorknob with a foot are provided.

However, although any of the above products can open and close the door without using hands, it is not possible to open and close the door and lock the door at the same time without using hands.

On the other hand, it is possible to prevent misplacement of small items, lock and unlock the lock, and attach it to the lock so that it does not interfere with the emergency unlock operation. Document 4) has been proposed and has become a known technique.

However, the proposal of such a "forgotten item prevention device for locks" is that the tray is a small item in a lock for locks that is attached to a lock attached to a door or a support and a tray for preventing forgotten items is attached. It is provided with a mounting part on which the lock can be placed, and is attached to the rotating part of the lock so that it can rotate sideways as the lock rotates, and is on the opposite side of the door or support to which the lock is mounted. The receiver is attached to the door, and the receiver is attached to a place that can support the tip side of the sideways tray mounting part. It is a proposal that the door can be opened and closed without using, but the lock device itself cannot be locked without using hands.

The applicant has identified the possibility of direct infection by contacting the doorknob and lock device of a lavatory booth such as a large facility where an unspecified number of people may come into contact as a cause of infection in a person whose infection route is unknown. interest, and to solve these factors, the door opening and closing device for the door lock equipment of uchikake expression that can be locked and unlocked operation from the inside of the door by flipping up toes are attached the legs without touching the hand It has been developed and leads to the proposal of the "door opening / closing device" in the present invention.
