JP3016461U - Automatic locking device for double doors of furniture such as cupboards - Google Patents

Abstract

(57) [Summary] [Purpose] During the Great Hanshin Earthquake, the doors of the "Kannon opening" cupboards were opened, and the falling dishes were scattered, damaged, and many were injured. In order to prevent such an accident, an object of the present invention is to devise a locking device that locks without performing any special operation (there is a risk of forgetting that the lock is a separate operation). [Structure] The present invention is composed of the following. 1, a locking metal fitting body 2 with an inverted L portion of claim 1, a receiving metal fitting 3 for receiving and locking the locking metal fitting, a reverse L portion of claim 1, pushing the locking metal fitting to release the lock rod

Description

[Detailed description of the device]

[0001]

[The purpose of the device]

 Due to vibrations such as an earthquake, furniture doors such as cupboards of double doors open, and contents such as tableware inside pop out and are damaged, or accidents occur when stepping on the damaged items. The purpose of this invention is to prevent such accidents by devising a metal fitting that can be opened easily under normal conditions without opening due to such vibrations and automatically locks (locks) every time it is closed.

[0002]

[Industrial applications]

 The present invention relates to a lock in consideration that the hinged door of furniture such as a cupboard is not opened unexpectedly due to vibration such as an earthquake.

[0003]

[Prior art]

 Conventionally, there were metal fittings for locking (locking) hinged doors, but these require two-action operation, such as closing the door and then locking (locking) again. Locking is a hassle, and it can be useless at critical times because it is not locked or forgotten.

[0004]

[Problems to be solved by the device]

 This invention is designed to enable the door to be unlocked and opened with a simple operation by closing the door without any special operation.

[0005]

【Example】

 I attached it to the cupboard of a double door. Normally, a double cupboard cabinet with a double door also has a single-sided cabinet next to it. An embodiment will be described below with reference to the accompanying drawings. FIG. 1 is a side view showing a state in which the locking fitting of FIG. 2, the receiving fitting of FIG. 3 and the unlocking stick of FIG. 4 are attached to a closet, and the handle 5 is grasped near the center of the door 6 and the thumb is held in that state. Fig. 4 Open the door hole 4 (which can be loosely inserted without resistance) for inserting the unlocking stick in the position where it can be easily pushed with, and insert the unlocking stick through it. Fix the hinge 1 of the locking metal fitting to the position inside the door with wood screws so that the part 2 hits. Figure 3 The receiving bracket is fixed to the middle shelf 7 of the furniture with wood screws at the position where it will be locked (locked) as an extension of the locking bracket. Figure 1 shows the door closed and locked (locked), and in this state it will not open due to vibration. When opening, the handle 5 is grasped, and the thumb for pushing the unlocking stick lightly pushes the reverse L part 2 of the locking metal fitting and pushes up the locking metal fitting to unlock it, so pulling the handle 5 as it is opens the door 6. When you release your finger, the locking metal fitting falls by its own weight (position when locking), and when you press the door 6 as it is, the locking metal fitting and the sloping part of the receiving metal fitting lock the locking metal fitting over the receiving metal fitting. If the weight of the locking metal fitting is light and it is difficult to lower (locking position), insert a weight in the triangular space of the locking metal fitting or use hinge 1 as a spring-loaded hinge.

[0006] Fig. 2 shows a metal fitting such as an aluminum plate having a width of 20 mm and a thickness of about 0.8 mm which is bent by a locking metal fitting.

1. One of the hinges 1 is fixed to a main body having an inverted L portion 2 with screws or rivets. The other part of this hinge 1 attaches to the door.

[0007] Fig.3, Receiving metal fittings Fig.2 Receiving metal fittings to be the receiving parts of the locking metal fittings, which are made by bending the same material as the locking metal fittings, and have an ellipse whose position can be finely adjusted for wood screw fastening to the middle shelf Make two holes 3 in.

As shown in FIG. 4, the unlocking push rod is a push rod that pushes up and unlocks the locking metal fitting by pushing the reverse L portion 2 of the locking metal fitting shown in FIG. 1 through the hole 4 formed in the door. Nail-shaped object made of metal, plastic, or wood according to the design of the door about 5 mm.

[0009]

[Effect of device]

 Conventionally, the door of the cupboard of the double door is locked with a magnet and a catch, and it took some force to pull and open the handle. As a result, this magnet and catch are not required, the door can be opened without any resistance, and it will not open unexpectedly due to the intended vibration, etc., and the safety effect will be great. A single door has the same effect.
