み型ラツチ装置に関するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an embedded latch device whose main portion is embedded in the door panel of a walk-in refrigerator, cabinet, or the like.

らの施錠を割愛せざるを得なかつた。(Problem to be solved by the invention) However, in such an embedded sliding latch device, in order to attach a lock for locking the latch body to the case, it is difficult to install a lock mounting body protruding from the front side of the latch body. When the latch body slides in the unlocking direction, the lock mounting portion collides with the front member of the case, making the sliding movement impossible. Therefore, with built-in latch devices, as long as the latch body is located on the back side of the door panel, removable locks such as padlocks and code locks cannot be used, and external locking must be omitted. I didn't get it.

出没自在に設けたものである。(Means for Solving the Problems) The embedded latch device of the present invention will be explained below using the reference numerals in the attached drawings. It consists of a latch body 4 which is housed in a door panel 3 and slides along the door panel 1, and a lock attachment body 5 mounted on the latch body 4, and the front end of the latch body 4 is fixed to a frame. It is provided so as to be freely retractable from the latch body 4 at a portion that is exposed on the front surface of the case 2 when engaged with the receiving portion 8 on the body 7 side.

よつて、扉パネル１に締付け固定される。(Embodiment) In the illustrated embodiment, the entire latch device is constructed such that the front plate 9 of the case 2 is brought into contact with the door panel 1 from the front side of the door panel 1, and the rear body 3 of the case 2 is brought into contact with the door panel 1 from the front side of the door panel 1. By screwing the nut 11 into the stud bolt 10 that abuts against the door panel 1 from the back side, is fixed to the front side plate 9, and is inserted through the mounting hole of the door panel 1 and the mounting hole 40 of the back side main body 3. Then, it is tightened and fixed to the door panel 1.

に保持される。 The cylindrical lock mounting body 5 fitted into the cylindrical guide wall 19 is slidably biased in the projecting direction by a compression coil spring 13 inserted between the cylindrical guide wall 19 and the bottom wall. The cylindrical guide wall 19 is provided with a circumferential groove 20 having an opening angle of about 90 degrees at its end, and an axial groove 21 perpendicular to one end of the circumferential groove 20 on its side surface. When the locking projection 16 of the lock mount 5 engages the circumferential groove 20, the lock mount 5 is held in the retracted position.
