Description

  The present invention relates to a release mechanism with an emergency escape function in a locking device with a cam. More specifically, for example, when another worker locks without noticing that an operator is in a storage room or the like. An operator confined indoors can operate the release mechanism with an emergency escape function attached to the locking device with a cam by himself to unlock it without using any tools. Further, the present invention relates to a release mechanism with an emergency escape function in a locking device with a cam.

  A locking device with a cam may be used for locking and unlocking a storeroom or a large refrigerator. When locking a locking device with a cam, for example, a colleague may lock without knowing that there is another worker indoors, or the door may be locked for some reason and the worker may be locked indoors. is there. In such an emergency, when there is no contact means such as a telephone requesting rescue, the trapped worker may suffer from dyspnea, frostbite, etc. or panic. The worst is happening.

  Many proposals have been made to prevent such misidentified locking accidents or for emergency release devices. For example, “Release mechanism with internal emergency escape function of door structure” in Patent Document 1 (see page 1, FIG. 1), “Emergency release device for slide door” in Patent Document 2 (see page 1, FIG. 1), Patent document 3 (refer to page 1, page 1) "Cold device door lock device", Patent document 4 (refer to page 1, page 1) "door device", patent document 5 (page 1, page 1) 1) “a door latch handle latching device”, and “a door lock handle device” of Patent Document 6 (see FIG. 1 on page 1).

  FIG. 1 shows a use state of a release mechanism with an emergency escape function (hereinafter referred to as a locking device with a cam LC) in a locking device with a cam according to the present invention. D is a door, DF is a door frame, R is a receiving member, and N is a door knob. FIG. 2 shows an exploded view of members constituting the cam-equipped locking device LC. S is a cylinder lock, and a cam plate 10 is attached to the outer cylinder tip S1. Normally, if the key K is inserted into the key hole S2 of the cylinder lock S and rotated, the cam plate 10 rotates 90 °. Then, locking and unlocking are performed. A pulling means 50 is attached to the indoor side of the cam plate 10. The emergency release function-equipped release mechanism 100 includes the cam plate 10, the sliding body 20, the cam plate mounting plate 30, the elastic member 40, and the traction means 50 as main components. The cam plate 10 is provided with a through hole 11 for mounting the seat plate W and the fixing bolt B at one end, and the cylinder 12 and the outdoor side of the cylinder 12 on the longitudinal center line on the indoor side of the through hole 11. A guide pin 13 is erected in the vicinity. The front portion 21 of the sliding body 20 is inserted into the cylindrical body 12, and the rear portion 22 protrudes outside through the opening 12 a of the cylindrical body 12 and is fitted so as to be movable back and forth within the cylindrical body 12. ing. The cam plate mounting plate 30 is provided with a square hole 31 communicating with the through hole 11 of the cam plate 10 at the base end portion, and a distal end portion 21 a of the sliding body 20 for locking and unlocking above the arcuate outer peripheral edge 32. A fitting hole 33 through which the guide enters and exits is provided, and an arcuate guide groove 34 is formed inside the fitting hole 33 to engage the guide pin 13 and slide it up and down. The elastic member 40 is mounted in the cylindrical body 12 and biases the sliding body 20 toward the cam plate mounting plate 30. For example, a coil spring is suitable. 21b is a flange which locks the end of the elastic member 40. The pulling means 50 is attached to the projecting portion 23 of the sliding body 20 and is used to pull out the distal end portion 21a of the sliding body 20 from the fitting hole 33 of the cam plate mounting plate 30 to the indoor side. A ring is preferred. The distal end portion 21a of the sliding body 20 has a diameter and length that fits into the fitting hole 33 of the cam plate mounting plate 30, and the sliding body 20 has a plan in which a flange 21b is provided in the vicinity of the distal end portion 21a. Can be a jar.

  Next, with reference to FIGS. 2-5, the assembly operation | work of the locking device LC with a cam is demonstrated. First, the elastic member 40 (coil spring) and the sliding body 20 (plunger) are inserted into the cylinder 12 from the opening 12b provided on the outdoor side of the cam plate 10, and the rear part 22 is opened to the opening 12a of the cylinder 12. And a traction means 50 (metal ring) is attached to the projecting portion 23, and the front end portion 21 a of the front portion 21 is fitted into the fitting hole 33 and the guide pin 13 is guided into the guide groove 34. Engage with. Next, the seat plate W is fitted into the through-hole 11 to communicate with the square hole 31 and fixed integrally with the cylinder lock S by the fixing bolt B, and the assembly operation of the cam-equipped locking device LC is completed.

  FIG. 3 shows a state viewed from the indoor side when the locking device with cam LC is locked. The cam plate 10 is in a horizontal state with the fixing bolt B as a base point. At this time, the tip 21a of the sliding body 20 (plunger) is fitted so as to be pressed against the fitting hole 33 by the biasing force of the elastic member 40 (coil spring), and the guide pin 13 is the uppermost part of the guide groove 34. 34a is engaged and locked.

FIG. 4 shows a state seen from the outdoor side when the locking device with cam LC is unlocked. In an emergency, that is, when the door D is locked for some reason despite the presence of a person indoors, if the person confined inside pulls the pulling means 50 (metal ring) toward the near side, the sliding body The distal end portion 21a of 20 (plunger) is released from the fitting hole 33 against the urging force of the elastic member 40 (coil spring) and is unlocked by moving the cam plate 10 in the release direction.
As described above, the present invention has a simple structure with a small number of parts, and a person confined indoors for some reason can escape to the outdoors with a simple, self-operated operation without being panicked. Became possible.

  As described above, the cam-equipped locking device LC according to the present invention has been described based on the embodiment thereof, but the present invention is not limited to the configuration described in the above-described embodiment, and does not depart from the spirit thereof.
