てあつて前記凹部４ａに嵌入している。 Reference numeral 5 denotes a hub that rotates together with an operating rod 6 that rotates by operating a knob, operating lever, etc. (not shown) from the outside, and the hub 5 includes an arm 5a.
A pin 7 is provided at the tip of the pin 7 and is fitted into the recess 4a.

２から没入させる。 To unlock this lock, operate a knob, operating lever, etc. from the outside to rotate the hub 5 in the counterclockwise direction shown in the figure via the operating rod 6, and the arm 5a will also rotate in the same direction. The pin 7 engages with the recess 4a to slide the plate 4 and therefore the bolt 3 to the right in the drawing, causing the bolt 3 to retract from the front plate 2 as shown in FIG.
ハブ５を上記と反対方向に回動することによつ
て、ボルト３を突出させて施錠を行なうことがで
きることは直ちに理解できるところであろう。 It will be readily understood that by rotating the hub 5 in the opposite direction to that described above, the bolt 3 can be projected and locked.

ハブ５の周辺適所に係止してある。 In such a locking device, the illustrated device has a deformable member 10 made of a material that expands and deforms with heat, such as a shape memory alloy such as Cu-Zn-Al or Ni-Ti, at one end of the deformable member 10. 10a is locked and fixed to the side wall portion 1'a formed on the side plate 1', and then the deformable member 10 is extended so as to surround the periphery of the hub 5 (at least over half of the outer circumference of the hub 5). The other end 10b (preferably surrounded) is locked in place around the hub 5.

ルト３が没入して解錠されることになる。 With this structure, when the indoor temperature rises to a preset temperature due to a fire, the deformable member 10 extends and deforms to envelop the hub 5, changing the state from the state shown in FIG. As shown in Figure 3, since the hub 5 is rotated, the bolt 3 is recessed and unlocked.

効果を有し、コストの面からも有利である。(3) Effects of the Invention As explained above, according to the present invention, when a fire occurs, the door lock automatically becomes unlockable due to the rise in temperature, and its structure is simple, and there are no special additional features. It is easy to modify known locks of this type without requiring any mechanism, and since the deformable member is firmly supported at both ends, it will not deform due to vibrations etc. during normal use of the door. The member does not come off from the predetermined position without your knowledge, which increases the safety of the lock, has a remarkable effect on preventing disasters, and is also advantageous in terms of cost.
