Definitions
- the present invention is attached between a door that closes an opening of an object with an opening such as a room or a box, and a wall of an object with which the door collides when the door is closed.
- a door that closes an opening of an object with an opening such as a room or a box
- a wall of an object with which the door collides when the door is closed With regard to door latches that hold them against unintentional opening, especially when one male or female latch member is displaced relative to the other female or male latch member to be connected to it to facilitate its coupling.
- the present invention relates to an improved door latch.
- a door latch is attached to a door that closes an opening of an object with an opening such as a box and a wall of an object that the door collides with when the door is closed.
- One latch unit has a male or female latch member fixedly held in a holder, and the other latch unit is held by the holder in a freely displaceable manner. It has a female or male latch member that should be inertially coupled so as to be secured to the male or female latch member (see Patent Documents 1 to 3).
- a latch unit that holds a displaceable latch member in addition to these conventional door latches includes a groove having an opening on the front surface of the holder that holds the latch member, and the latch member includes: The base portion is inserted into the groove through the opening, and is held while being prevented from coming off so that it can be displaced in the groove.
- the latch member has a base that can be displaced left and right in the groove of the holder (see Patent Documents 1 and 2) or swinging in the groove (see Patent Document 3). ing. Note that the latch member that displaces left and right within the holder is normally urged so as to be positioned at the center of the groove by springs disposed on both sides thereof.
- the latch member that can be displaced to the left and right is a force that has a retaining piece at the base so that the groove force of the holder cannot be pulled out.
- the latch member When inserting into the groove, the latch member must be inserted while being folded, so the assembly of the latch member is troublesome, and the latch member that can swing freely has its shaft part held in the groove of the holder. The assembly was troublesome in the same way.
- latch members are all inserted through the opening in the front of the holder while bending the shaft portion of the retaining piece.
- This insertion direction is the same direction as the coupling direction of the two latch units. Therefore, if the coupling of the latch member is strong, when the door is opened, the mating latch member may come out of the holder while bending the shaft, and the function of the latch will be hindered.

- One object of the present invention is for a door in which a displaceable latch member can be easily inserted and assembled into a holder, and the latch member does not come out of the holder force unintentionally. To provide a latch.
- Another object of the present invention is to provide a door latch capable of assembling a displaceable latch member to a holder with one touch.
- the basic feature of the present invention is that the first and second latches respectively attached to the door that closes the opening of the object with the opening and the wall of the object that the door collides when the door is closed.
- One latch unit has a male or female latch member fixedly held in the holder, and the other latch unit is slidably held in the holder so that the male or female of one latch unit can be displaced.
- the other latch unit holder is connected in the direction in which the first and second latch units are joined.
- a corresponding latch member hereinafter referred to as a displacement latch member of the other latch unit.
- the base has a base inserted into the groove through the slot in the holder groove and a neck that extends through the base through the slot in the holder groove. It is providing the latch for doors characterized by these.
- the displacement latch member has elastic claws on both sides in front of the neck portion. This elastic claw is locked to the holder locking portion so that the displacement latch member is prevented from slipping in the insertion direction when the displacement latch member is inserted into a predetermined position of the groove of the holder. Is preferable.
- the base of the displacement latch member has a direction opposite to the locking direction before the displacement latch member is inserted into the groove of the holder. It is preferable to have a notch that allows the elastic pawl to engage the holder wall.
- the holder of the other latch unit having the displacement latch member includes the insertion opening that opens in a direction different from the coupling direction of the one latch unit, and the latch of the one latch unit.
- the displacement latch member has a base inserted into the groove through the slot insertion slot of the holder, and extends through the base slot and penetrates the slot of the holder groove. Since the displacement latch member has the neck portion, the displacement latch member can be assembled to the holder by simply inserting the displacement latch member into the holder groove without causing the base portion to be folded. Therefore, the latch unit can be easily assembled.
- the displacement latch member is firmly retained by the base portion being hooked on the groove wall.
- the elastic claw provided in front of the neck portion of the displacement latch member prevents the displacement latch member from coming off from the insertion direction when the displacement latch member is inserted into a predetermined position of the groove of the holder.
- the base of the displacement latch member is engaged with the wall of the holder so that the elastic pawl is held in a direction opposite to the locking direction before the displacement latch member is inserted into the groove of the holder.
- the elastic claw is restored. Because it is locked to the holder's locking part by force, the displacement latch member that does not require troublesome operations such as spreading the elastic claws by hand can be assembled to the holder with one touch, making it easy to assemble the latch unit. It can be carried out.
