Abstract

PURPOSE: To prevent the generation of noise at the time of opening a door by installing a pair of pressing pieces to a latch main body mounted energetically to a door rail with a spring in the projecting direction, and press-bonding the piece with a guide wall of a latch case so as to eliminate the shaking of the door. CONSTITUTION: A pair of pressing pieces 34a are installed to a sliding part 34 of a head 31 energized in the projecting direction with a spring 13 installed to a latch main body 12 which holds a folding door of a bathroom or the like and is contact-bonded with a guide wall 23 of a latch case 11. When the latch main body 12 is assembled in the latch case 11, the pressing pieces 34a are adapted to act so as to bury the clearance with the guide wall 23 of the latch case 11, thereby preventing the latch main body 12 from being shaky. In the case when the door is closed, the head 31 is pushed to a locking rail or the like installed to a door frame on a skeleton side against the force of a spring 13 and pushed down and locked therewith. This construction makes it possible to prevent a jarring noise from being generated when the door is closed.

2. Description of the Related Art Conventionally, as a latch for this type of door, the one disclosed in Japanese Utility Model Laid-Open No. 61-197170 is known. The latch is attached to the door body of the folding door, and is configured to be hooked / unhooked on a rail formed on the frame body of the folding door as the door body is opened and closed. The latch is composed of a latch case having a protruding / retracting opening formed on the end surface on the frame body side, a latch body housed in the latch case so that the head part protrudes / retracts from the protruding / retracting opening, and a coil spring that biases the latch main body in the protruding direction. ,It is configured. A rubber ring for shock absorption is attached to the stepped portion between the head portion and the body portion on the latch body, and when the latch is engaged / disengaged,
When the head part moves from the retracted state to the protruded state by the coil spring, the rubber ring hits the retaining part of the latch case to absorb the impact and suppress the generation of unpleasant sound from the latch. .

However, the unpleasant sound that is generated when the latch is engaged and disengaged is not generated by the head portion projecting and the body portion hitting the retaining portion of the latch case, but caught by the rail. The tilted latch body
When it comes off the rail, it hits the guide wall that connects to the opening / closing opening. That is, not the vertical movement of the latch body but the movement in the front-back direction with respect to the tilting direction of the latch body is a main source of unpleasant sound. In this type of latch, a clearance is provided between the guide wall of the latch case and the head portion due to manufacturing problems and sliding problems of the latch, and rattling between members based on this clearance is provided. Is considered to be the cause of the unpleasant sound. Therefore, even if the rubber ring is used, it is not possible to sufficiently suppress the generation of annoying and unpleasant sound.

The head portion 31 has a substantially mountain-shaped cross section,
The upper half of the upper surface is formed as a flat inclined surface on the hanging side, and the latter half of the detached side is formed as a curved inclined surface. This ensures that the rail 8 is locked,
And it can be hung and removed smoothly. The left and right side portions of the butting portion 32 are provided with retaining portions 24 a, 24 of the latch case 11.
The protrusion portions 32a and 32a are in contact with a. The protrusion portions 32a are formed obliquely to the left and right with respect to the retaining portion 24a. As a result, the abutting portion 32 that is urged by the spring 13 and hits the retaining portion 24a,
The component forces of the springs 13 act on each other inwardly, and the position of the head portion 31 is regulated at the center of the retractable opening 22 in the left-right direction. That is, the head portion 31 and the retractable opening 22 are arranged in the left-right direction.
There is a necessary clearance between and when assembling,
Due to the component force of the spring 13, the protruding head portion 31 is held without rattling with respect to the projecting / retracting opening 22. As a result, generation of sound due to rattling between the head portion 31 and the retractable opening 22 is suppressed.

The shaft portion 33 extends downward from the lower end surface of the head portion 31, and the tip portion is inserted into the guide hole 25 of the latch case 11. The base end portion of the shaft portion 33 is formed in a circular cross section and the tip end portion is formed in a semicircular cross section.
Is formed obliquely from the base end portion to the tip end portion in a direction parallel to the surface direction of the window portion 24 of the latch body 1 of the latch case 1.
The shaft portion 33 of the latch main body 12 can be inserted into the guide hole 25 from an obliquely upper side when it is assembled into the accommodation portion from the first window portion 24. In addition, a slit 35 extending in the longitudinal direction is formed in the shaft portion 33 so that bending of the shaft portion 33 itself can be permitted to some extent.

As described above, since the tip of the shaft portion 33 is formed in a semicircular cross section and the shaft portion 33 has flexibility, the shaft portion 33 can be easily inserted into the guide hole 25. Further, the slit 35 of the shaft portion 33 allows bending of the shaft portion 33 itself and smoothly guides the head portion 31 to move in and out while tilting. Further, by doing so, the clearance between the shaft portion 33 and the guide hole 25 can be eliminated, and the generation of sound due to rattling between the both can be suppressed. Further, the shaft portion 33 is slightly eccentric in the middle portion, and the spring 13 wound around the shaft portion 33 is restricted in lateral movement at the base end portion, the middle portion and the tip end portion of the shaft portion 33 to prevent rattling. It is installed. This allows
Generation of sound due to rattling between the shaft portion 33 and the spring 13 can be suppressed.

As described above, according to this embodiment, it is possible to prevent the rattling between the guide wall 23 and the projecting / retracting opening 22 and the head portion 31 while maintaining the necessary clearance therebetween. Therefore, both the sound generated directly and the sound generated indirectly due to the impact generated when the latch 10 is engaged / disengaged can be suppressed. Furthermore, by preventing rattling between the guide hole 25 and the shaft portion 33 and between the shaft portion 33 and the spring 13, it is possible to further suppress the sound generated. Therefore, it is possible to effectively prevent an unpleasant latching sound generated when the folding door 1 is opened and closed without impairing the assembling property.
