Description

  The present invention relates to a temperature-sensitive movable device and a temperature-sensitive closing damper.

As an operating mechanism of a damper device, etc. that detects the ambient temperature and wants to operate when it reaches a certain temperature, a certain metallic material (fuse metal) is softened at 80 ° C., for example. The movement of the movable pin inserted into the cylinder by the spring is stopped, and the movement of the movable pin that starts moving with the force of the spring when the metal material reaches the melting temperature can be used as a start signal for a damper device, etc. Thermally movable devices are known.
The damper device installed in the fire prevention compartment of air conditioning ducts in various buildings, factories, etc. is temperature-sensitive as a mechanism to keep the damper blade spring-biased in the closing direction open in the casing arranged in the fire prevention compartment A device is used, and this temperature-sensitive movable device can supply air constantly while keeping the drive of the damper blade locked.
In addition, by positioning the temperature-sensitive part of the temperature-sensitive movable device with the fuse metal in the air-conditioning duct, in the event of a fire, the temperature-sensitive movable device is operated with the high-temperature airflow that passes through the air-conditioning duct, and the damper blade locks. Is opened and the spring-biased damper blades are rotated to automatically close the inside of the casing for flame and fire prevention.

  However, normally, in a fire, the smoke is faster than the fire, so when the temperature-sensitive movable device is activated by the high temperature airflow, the smoke is filled up everywhere. Furthermore, the majority of deaths resulting from the occurrence of fires, etc. are not pure death, but suffocation and poisoning due to inhalation of gas and smoke such as carbon monoxide. Therefore, a temperature-sensitive movable device that operates with a high-temperature air current cannot prevent damage caused by smoke or gas such as oxygen monoxide poisoning, which is the most common cause of death due to a fire.

  Therefore, a smoke sensor that detects smoke in air conditioning ducts, etc., in order to prevent the spread of smoke such as carbon monoxide, as a device that unlocks the damper blades locked in the casing, separately from the temperature-sensitive movable device The solenoid coil is energized by an electrical signal from the motor, and the movement of the solenoid's suction shaft is used as an activation signal to unlock the damper blade. When smoke is generated, the damper blade rotates to automatically close the casing. A fireproof damper has been proposed (Patent Document 1).

Japanese Patent Laid-Open No. 2001-299948

In Patent Document 1, a solenoid driven by a smoke sensor is used, and the solenoid is activated when the smoke sensor detects smoke. Then, the restraint of the torque spring is released by moving the locking pin against the compression reaction force of the spring. Thereby, the filling of smoke can be prevented by rotating the blade shaft of the damper blade and closing the air conditioning duct.
However, in addition to the conventional temperature-sensitive movable device, another smoke detection drive mechanism, that is, a mechanism that moves the locking pin against the compression reaction force of the spring to release the constraint of the torque spring and rotates the blade shaft is doing. Therefore, the said patent document 1 is equipped with two mechanisms, the mechanism by the temperature-sensitive movable apparatus for rotating a blade shaft directly, and the smoke detection drive mechanism. For this reason, the entire structure of the sensing drive mechanism becomes large, and it is necessary to provide another sensing drive mechanism in addition to the conventional temperature-sensitive movable device, and there is a problem that the cost increases due to an increase in the number of parts.

  An object of the present invention is to provide a compact temperature-sensitive movable device and a temperature-sensitive closing damper using the temperature-sensitive movable device that can be driven in association with detection of another state in addition to detecting a high temperature. There is.

Means for solving the problems and effects of the invention

In order to solve the above problems, the temperature-sensitive movable device of the present invention is:
A thermal fuse that is locked to one end of a cylindrical frame and that can move a movable pin that is housed at a predetermined temperature, and a tip projecting from the other end of the frame and a temperature at the other end A movable member held by the movable pin of the fuse and accommodated in the frame, and a spring for biasing the movable member toward the movable pin;
In the temperature-sensitive movable device in which the protrusion amount of the tip portion protruding from the other end portion of the frame body changes when the movable pin that has stopped moving due to the force of the spring of the movable member can move due to the temperature rise,
The movable member has a link mechanism interposed between the main body including the tip driven by the spring and the other end held by the movable pin of the thermal fuse,
In the link mechanism, a first link member that is rotatably coupled to the other end held by the temperature fuse and a second link member that is rotatably coupled to the main body are rotatably connected by a support shaft,
The first link member or the second link member is provided with a contact portion for maintaining the bending by the support shaft of the link mechanism in a substantially linear shape,
In the vicinity of the abutting part, a link stopper that stops the bending of the link mechanism by locking to the abutting part is arranged,
The urging force of the spring is applied to the other end held by the movable pin of the thermal fuse via a substantially linear link mechanism with the bending stopped by the link stopper,
Provided with a link stopper driving means that can release the locking between the contact portion and the link stopper by the input of an electrical signal,
When the link stopper is moved by the link stopper driving means, the engagement between the contact portion and the link stopper is released, and the first link member and the second link member are bent around the support shaft,
The biasing force of the spring is characterized in that the main body is moved by a link mechanism that bends even when the thermal fuse is inoperative, and the amount of protrusion of the tip is changed.

The temperature-sensitive movable device according to the present invention includes a cylindrical frame, a temperature fuse that allows a movable pin mounted at a predetermined temperature to move, a movable member, and a spring that biases the movable member in the direction of the movable pin. Then, the movable pin stops moving by the force of the spring that biases the movable member in the direction of the movable pin. When the movable pin becomes movable due to a temperature rise, the force of the spring stopped by the movable pin is released, and the temperature-sensitive movable device projects from the other end of the cylindrical frame. The amount of protrusion at the tip of the is changed. That is, the temperature-sensitive movable device changes the protruding amount of the movable member when the temperature fuse is activated.
Further, the movable member has a main body portion having a tip portion, a link mechanism in which the first link member and the second link member are linked by a support shaft, and the first link member and the second link member are in an open state (substantially). Place a link stopper that keeps it on a straight line. And the spring which urges the main-body part of a movable member closes the 1st link member and the 2nd link member by releasing the latching of a link stopper by a link stopper drive means (bending centering on a spindle) As a result, the main body can change the protruding amount of the tip. That is, even when the thermal fuse is not activated, the link driving means is activated, so that the link mechanism is closed and the protruding amount of the movable member is relatively changed.

  As described above, the temperature-sensitive movable device of the present invention can be reliably driven by the input of an electric signal given from the outside in addition to detecting a high temperature. That is, a link mechanism is built in a movable member that is movable by the operation of a thermal fuse, and a link stopper that maintains the link mechanism in an open state is used. The main body can also be moved by driving the link stopper driving means to release the lock between the link stopper and the link mechanism. That is, the movable member can be reliably operated based on a signal other than the thermal fuse in the temperature-sensitive movable device. Therefore, it is possible to provide a compact temperature-sensitive movable device while utilizing the configuration of the thermal fuse. In addition, even if the fuse metal does not melt at a predetermined temperature due to deterioration of the fuse metal, etc., it is possible to drive the temperature-sensitive movable device by wiring so that an electrical signal output from another temperature detection device can be used. Become. Therefore, it is possible to ensure the driving reliability of the temperature-sensitive movable device.

  Moreover, the temperature movable apparatus of this invention is equipped with a link mechanism between the main-body part of the movable member movable by the action | operation of a thermal fuse, and an other end part. And the link stopper drive means which drives the said link mechanism is employ | adopted. That is, a drive unit that drives a link mechanism, which is a part of the movable member in the temperature-sensitive movable device, is provided. Therefore, since the drive portion is a link mechanism in the movable member in the temperature-sensitive movable device, even when a drive means for driving the link mechanism is provided, the drive means is not so large, and the temperature-sensitive movable device. The whole is compact (in the case of Patent Document 1, the blade drive unit that is electrically operated is large because the drive part is a blade shaft). And since a part of link mechanism of a warm feeling movable apparatus should just be moved, in order to move this link mechanism, big force is not required. Therefore, also from this viewpoint, the temperature-sensitive movable device of the present invention is compact. Therefore, since the temperature-sensitive movable device becomes compact, the temperature-sensitive movable device can be easily used for various products.

  In this case, in the temperature-sensitive movable device of the present invention, the electrical signal for driving the link stopper driving means can be an electrical signal generated when the smoke detector detects smoke. Therefore, it is possible to provide a temperature-sensitive movable device that operates by detecting smoke with respect to a conventional thermal fuse that operates only by detecting a high temperature.

And in the temperature-sensitive movable device of the present invention,
The link stopper is arranged so as to be rotatable around the rotation axis,
The link stopper driving means is composed of a solenoid that is driven by the input of an electric signal, a suction shaft that is moved by the magnetic force of the solenoid, and an engagement shaft that is provided on the suction shaft to drive the end of the link stopper.
It can be configured such that the link stopper and the contact portion are unlocked when the solenoid suction shaft is suctioned.

  The link stopper is rotatable about the rotation axis, and the end of the link stopper is engaged with the suction shaft that is movable by the magnetic force of the solenoid. Therefore, the link stopper is rotated by the solenoid driven by the input of the electrical signal. In this case, since the link stopper rotates about the rotation axis, the dynamic friction portion between the contact portion and the link stopper can be pushed to the minimum area. For this reason, the link stopper and the contact portion can be unlocked even with a minute force by the solenoid, and the temperature-sensitive movable device can be easily driven by a minute electric power.

On the other hand, the temperature-sensitive movable device of the present invention is
A contact portion is formed at the end on the support shaft side of the first link member that is rotatably coupled to the other end held by the thermal fuse,
When the movable pin can move due to a temperature rise, the first link member can move together with the other end, and the engagement between the contact portion and the link stopper can be released.

  When the contact portion is formed at the end of the second link member on the support shaft side, the first link member and the second link member are caused by the contact portion even when the engagement between the contact portion and the link stopper is released. There is a possibility that the abutment part restricts the movement of the main body part constituted by That is, when the contact portion is disposed toward the movable pin of the main body portion, the contact portion may be caught when the movable member moves, and the bent state of the link mechanism may be limited by the contact portion. . For this reason, there is a possibility that the protruding amount of the tip cannot be changed sufficiently. However, a contact portion is formed at the end on the support shaft side of the first link member that is rotatably coupled to the other end portion held by the thermal fuse, so that the contact portion is arranged toward the tip portion. Thus, when the movable member moves, the contact portion is formed in a direction opposite to the movable direction of the movable member, so that the bent state of the link mechanism is not limited. Therefore, the tip portion can move the movable pin of the thermal fuse without obstructing the movement, and the operation of the warm-sensitive movable device can be surely ensured.

Moreover, the temperature-sensitive movable device of the present invention is
Link mechanism return means for returning the first link member or the second link member at the bent position to a substantially straight line against the accumulated force of the spring,
The link mechanism return means includes at least a return lever provided with an operation part on one side and a link engagement part engaged with the bent position of the link mechanism on the other side, and a return spring for returning the return lever to the bent position of the link mechanism. And can have.

When the link stopper driving means is driven, the lock between the link stopper and the contact portion is released. And a link mechanism drives, a main-body part is moved and the protrusion amount of a front-end | tip part changes. In this case, the link mechanism can be returned to the original substantially straight state by providing the link mechanism return means. In addition, since it has at least a return lever with an operating part on one side and a link engaging part that engages the bent position of the link mechanism on the other side, the return operation can be performed with a single touch, making it easy to return It can be performed. Furthermore, by having a return spring that returns the return lever to the bent position of the link mechanism, the return lever is pulled back to the bent position of the link mechanism even when the link stopper is released from the contact portion. Therefore, the return lever does not limit the bending of the link mechanism, and it is possible to reliably drive the warm feeling movable device.
Normally, smoke is faster in the fire than smoke, so if the link stopper drive means is a smoke detector, the link stopper drive means is driven before the thermal fuse is activated. When the spread of fire due to a fire does not reach a wide area, especially in the case of a small fire, the thermal fuse does not operate, so it is not necessary to replace the thermal fuse. Therefore, it is possible to use the warm feeling movable device as it is by returning the warm feeling movable device to the original state by the link mechanism returning means.

Furthermore, the temperature-sensitive closing damper of the present invention is
A driving means for driving the damper disposed in the duct toward the closed position, and a lock portion capable of stopping the movement of the driving means for holding the damper at the open position,
The tip of the temperature-sensitive movable device is locked to the lock, and when the protrusion of the tip is reduced, the lock and the tip are unlocked, and the drive means directs the damper in the duct toward the closed position. It is made to move.

  By locking the tip of the temperature-sensitive movable device to the lock portion that holds the damper at the open circuit position, when the temperature-sensitive movable device is driven by driving a thermal fuse or driving a link stopper drive mechanism, the lock portion As a result, the driving means moves the damper in the duct toward the closed position. Therefore, it is not necessary to dispose the solenoid flanger drive mechanism separately from the thermal fuse drive mechanism as in the fireproof damper disclosed in the above-mentioned Patent Document 1, and there is no need for two installations. Can be greatly simplified. In addition, it is possible to provide a temperature-sensitive closing damper that reliably closes even with an external signal other than the thermal fuse. Therefore, it is possible to prevent the spread of fire and the filling of smoke due to fire.

  And the temperature-sensitive closing damper of this invention can be comprised so that the said thermal fuse may be located in the said duct. For this reason, when the inside of the duct reaches a predetermined temperature due to a fire, the thermal fuse is surely activated. Therefore, it is possible to reliably prevent the spread of fire due to fire. Furthermore, it is possible to prevent the smoke from being filled by the link stopper driving mechanism.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described with reference to the accompanying drawings. FIG. 1 shows a cross-sectional view of a temperature-sensitive movable device 1 of the present invention. The warm sensation movable device 1 of the present invention has a cylindrical frame 2. The frame 2 is tapered from the vicinity of the end 3 of the frame 2, and the diameter of the frame 2 decreases toward the end 3. Further, a wire 2 a having a start point and an end point at opposite points of the end 3 of the frame 2 is provided at the end 3 of the frame 2 as a temperature fuse fixing portion for fixing the temperature fuse 5. It is attached so that it can rotate on the basis of the part 3. The thermal fuse 5 is joined and fixed by a certain kind of metal material (fuse metal) by inserting the cylindrical movable pin 4 through the tapered hollow conical cylinder 5a. Therefore, when the fuse metal is melted at a predetermined temperature and a driving force is applied to the movable pin 4 provided in the thermal fuse 5 from the outside, the movable pin 4 can move. The intermediate portion of the wire 2a is formed in a hook shape so that the intermediate portion of the wire 2a formed in the hook shape is hooked on the end of the tapered hollow conical cylinder 5a of the thermal fuse 5. The thermal fuse 5 can be attached to the cylindrical frame 2. Specifically, the thermal fuse 5 is opposed to the external driving force until the hook-shaped portion of the wire 2a is hooked on the end of the tapered hollow conical cylinder 5a of the thermal fuse 5, and the thermal fuse 5 is connected to the end of the frame 2 3 is inserted into the inside of the frame 2. Then, the wire 2 a is rotated in the extending direction of the end portion 3 of the frame 2, and the hook-shaped wire 2 a is hooked on the end of the tapered hollow conical cylinder 5 a of the thermal fuse 5. As a result, the driving force applied from the outside to the movable pin 4 housed in the temperature fuse 5 is held by the hook-shaped wire 2 a, so that the temperature fuse 5 can be connected to the cylindrical shape with the driving force stored in the movable pin 4. It can be attached to the frame 2. That is, the intermediate portion of the wire 2a as the temperature fuse fixing portion is conventionally formed in a hook shape so that the temperature fuse 5 is removed from the opposite side of the end portion 3 of the cylindrical frame 2. There is no need to insert the thermal fuse 5 toward the end 3, and the thermal fuse 5 can be simply installed by only inserting the thermal fuse 5 from the end 3 of the cylindrical frame 2 and hooking the hook-shaped wire 2 a. It becomes possible to attach to the cylindrical frame 2.

The other end 3a of the cylindrical frame 2 is provided with a cap 2b that fits with a part of the cylindrical frame 2 by an elastic member such as a screw or rubber packing. Therefore, when the cap 2b is fixed by a screw, the cap 2b and the cylindrical frame 2 can be firmly fixed. When the cap 2b is fixed to a part of the cylindrical frame 2 by an elastic member such as rubber packing, the cap 2b is fixed to the cylindrical frame 2 because it is fixed by frictional force. The cap 2b can be easily attached and removed.
The cap 2b is provided with a through hole so that the distal end portion 6 of the movable member 8 inserted through the cylindrical frame 2 protrudes from the cap 2b. On the other hand, the other end portion 7 of the movable member 8 is provided with a fitting portion for fitting with the movable pin 4 of the thermal fuse 5.

The movable member 8 includes a first flange portion T1 in the vicinity of the other end portion 7. Further, in the vicinity of the main body portion 10 including the distal end portion 6, a second collar portion T <b> 2 for storing the elastic force of the spring 9 for biasing the movable member 8 toward the movable pin 4 is provided. In the movable member 8 inserted through the cylindrical frame 2, an elastic force is generated between the cap 2 b and the second collar T 2 by inserting a spring 9 between the cap 2 b and the second collar T 2. Stored. Therefore, when the cap 2 b is fixed, the spring 9 can always urge the movable member 8 toward the movable pin 4.
The movable member 8 is inserted from the other end portion 3a of the cylindrical frame 2 with the cap 2b removed to the end portion 3 with the other end portion 7 at the head, and the movable member 8 includes the first end portion 6 of the main body portion 10 including the front end portion 6. A spring 9 is inserted between the second flange T2 and the tip 6. The movable member 8 is attached by inserting the cap 2b into the main body 10 so that the tip 6 protrudes from the through hole of the cap 2b, and fixing the cap 2b to the cylindrical frame 2. On the other hand, when removing the movable member 8, the cap 2 b is removed from the cylindrical frame 2, and the movable member 8 is moved from the other end 3 a of the cylindrical frame 2 to the leading end 6 as a head. The movable member 8 is removed by being extracted from the body 2.

  Further, the movable member 8 has a link mechanism 11 interposed between the main body portion 10 including the distal end portion 6 driven by the spring 9 and the other end portion 7 held by the movable pin 4 of the thermal fuse 5. Specifically, the movable member 8 rotatably couples the first lower end portion 12b of the first link member 12 constituting the link mechanism 11 above the first collar portion T1, and the second collar portion T2. A second upper end portion 13a of the second link member 13 constituting the link mechanism 11 is rotatably coupled to the lower side. Then, the second lower end portion 13 b of the second link member 13 is rotatably connected by the support shaft 14 in the vicinity of the center portion of the first link member 12. By forming the support shaft 14 in the vicinity of the center portion of the first link member 12, a first upper end portion 12 a that is an end portion of the first link member 12 is formed toward the distal end portion 6 of the movable member 8. ing.

  Here, in order to maintain the link mechanism 11 of the first link member 12 and the second link member 13 on a substantially straight line, a contact portion 15 is provided on the first upper end portion 12 a of the first link member 12. In the vicinity of the contact portion 15, a link stopper 16 is disposed that is engaged with the contact portion 15 so as to maintain the link mechanism 11 on a substantially straight line. It has the latching | locking part 16a latched to the contact part 15 of the upper end part 12a. Further, the link stopper 16 has an engagement shaft 22 at one end facing the locking portion 16a. And the rotation axis | shaft 19 which rotates the link stopper 16 rotatably between the said latching | locking part 16a and the said engagement shaft 22 is provided. The engaging portion of the link stopper driving means 17 is engaged with the engaging shaft 22, and when the link stopper driving means 17 is driven by an external electric signal, the link stopper 16 is centered on the rotating shaft 19 and the seesaw. By performing the movement, the locking portion 16a of the link stopper 16 can be unlocked from the locked contact portion 15 of the first link member 12.

The link stopper driving means 17 of the embodiment is constituted by a solenoid 20. When an electric signal is applied to the solenoid 20 from the outside, a line of magnetic force is generated, and the suction shaft 21 attracts the solenoid 20 while compressing the solenoid spring. Moving. As a result, the link stopper 16 engaged with the suction shaft 21 of the solenoid 20 by engaging the engaging portion of the suction shaft 21 with the engagement shaft 22 is counterclockwise in FIG. Energized to rotate around.
When the link stopper driving means 17 is an electric motor, the electric motor is driven by the input of an electric signal, so that a driving member by the electric motor drives the link stopper 16 via the engagement shaft 22. In particular, when the temperature-sensitive movable device 1 as a whole is increased in size, the movable member 8 of the temperature-sensitive movable device 1 is also increased in size and the link mechanism 11 is increased. It becomes possible to move the warm feeling movable apparatus 1 reliably by making it small.

  As described above, in the temperature-sensitive movable device 1 of the present invention, the temperature fuse 5 is fixed by the wire 2 a attached to the cylindrical frame 2. The movable pin 4 fixed to the hollow conical cylinder 5a of the thermal fuse 5 by the fuse metal is fitted by a fitting portion at the other end 7 of the movable member 8 to which the first link member 12 of the link mechanism 11 is coupled. As a result, the link mechanism 11 and the thermal fuse 5 are connected. The link mechanism 11 is maintained on a substantially straight line by the link stopper 16. Therefore, the spring 9 inserted between the second collar portion T2 of the main body portion 10 located above the second link member 13 of the link mechanism 11 and the cap 2b of the cylindrical frame body 2 is a cylindrical frame body. The elastic force is stored between the second cap 2b and the second flange T2. Therefore, the spring 9 always biases the movable member 8 toward the movable pin 4. That is, by fixing the temperature fuse 5, the movable member 8 is always biased toward the movable pin 4 by the spring 9 when the link mechanism 11 is maintained on a substantially straight line. And in this state, the front-end | tip part 6 of the main-body part 10 of the movable member 8 has become the predetermined protrusion amount from the cap 2b.

Hereinafter, the operation of the above-described temperature-sensitive movable device 1 of the present invention will be described. FIG. 3 is a cross-sectional view showing a state in which the temperature-sensitive movable device 1 is moved by melting when the fuse metal of the temperature fuse 5 of the temperature-sensitive movable device 1 of the present invention reaches a predetermined temperature. In the temperature-sensitive movable device 1 of the present invention, when the temperature fuse 5 fixed by the wire 2a attached to the end 3 of the cylindrical frame 2 reaches a predetermined temperature, the hollow cone of the temperature fuse 5 is used. The fuse metal which fixed the movable pin 4 inserted in the cylinder 5a melts. Therefore, the movable member 8 always biased in the direction of the movable pin 4 by the spring 9 transmits the bias of the spring 9 to the movable pin 4 of the thermal fuse 5 by using the link mechanism 11 maintained in a substantially straight line as a medium. Then, the movable pin 4 fixed to the hollow conical cylinder 5a by melting the fuse metal is inserted deeply into the hollow conical cylinder 5a. That is, the movable pin 4 slides inside the hollow conical cylinder 5 a by the bias of the spring 9, and the other end portion 7 of the movable member 8 also moves toward the other end portion 3 of the frame body 2. Therefore, the distal end portion 6 of the movable member 8 also moves toward the inside of the frame 2 using the link mechanism 11 maintained on a substantially straight line as a medium. Therefore, the warm sensation movable device 1 of the present invention reduces the protruding amount of the tip 6 by releasing the urging force of the spring 9 while maintaining the link mechanism 11 on a substantially straight line. Therefore, the warm feeling movable apparatus 1 which can move with temperature can be provided.
In the present invention, since the movable member 8 is provided with the link mechanism 11, when the movable pin 4 welded to the hollow conical cylinder 5 a of the temperature fuse 5 slides by the biasing force of the spring 9, If the first link member 12 operates to a position where the locking of the contact portion 15 and the locking portion 16a of the link stopper 16 is released, the first link member 12 and the second link member 13 are instantaneously centered on the support shaft 14. Since the end portion 6 is bent inward and moves inward of the frame 2 by the force of the spring 9, the operation by the thermal fuse 5 is ensured.

  On the other hand, FIG. 4 is a cross-sectional view showing a state in which the temperature-sensitive movable device 1 is moved by driving the link stopper driving means 17 of the temperature-sensitive movable device 1 of the present invention. In the temperature-sensitive movable device 1 of the present invention, the temperature-sensitive movable device 1 is moved when the link stopper 16 is driven by the input of an electric signal to the link stopper driving means 17.

  When the link stopper driving means 17 is the solenoid 20, when electricity is supplied to the solenoid 20, the suction shaft 21 is attracted by the magnetic force of the solenoid 20, and the engaging portion of the suction shaft 21 is the engagement shaft 22 of the link stopper 16. The link stopper 16 can be rotated around the rotation shaft 19. Since the locking portion 16a of the link stopper 16 moves in the direction opposite to the suction direction, the locking between the contact portion 15 of the first upper end portion 12a of the first link member 12 and the engaging portion 16a of the link stopper 16 is released. . On the other hand, the urging force urged to the second flange T2 of the main body 10 by the spring 9 is always transmitted to the second link member 13, and the first lower end 12b of the first link member 12 is connected to the thermal fuse 5. Therefore, as soon as the engagement between the contact portion 15 of the first link member 12 and the locking portion 16a of the link stopper 16 is released, the biasing force of the spring 9 causes the first link member 12 and The link mechanism 11 is bent around the support shaft 14 of the second link member 13 and the urging force of the spring 9 is released. Along with the bending of the link mechanism 11, the distal end portion 6 of the movable member 8 relatively moves toward the inside of the frame body 2, and the protruding amount of the distal end portion 6 can be reduced.

When the temperature-sensitive movable device 1 is moved by the link stopper driving means 17, the link stopper 16 needs to be locked to the contact portion 15 of the first upper end portion 12 a of the first link member 12. Therefore, since the link stopper 16 is engaged with the first link member 12, the cylindrical frame 2 has a link corresponding to the contact portion 15 of the first link member 12 maintained on a substantially straight line. It is necessary to provide a notch so that the stopper 16 and the first link member 12 can be locked.
However, in the embodiment shown in the figure, the support shaft 14 between the second link member 13 is disposed in the middle of the first link member 12, and the first link member 12 and the second link member 13 are connected to the support shaft 14. Therefore, the first upper end portion 12a of the first link member 12 is positioned outside the cylindrical frame 2, and the first link 12 includes a first link. It is only necessary to provide a notch for securing a movable track when the member 12 and the second link member 13 are bent around the support shaft 14.

  As described above, in the thermal sensation movable device 1 of the present invention, the movable member 8 is reliably secured on the basis of the existing thermal fuse 5 and the two activation signals including the signals of the artificial operation and other detection sensors. It became possible to operate. As a configuration for this, the movable member 8 is provided with a link mechanism 11, and the first link member 12 and the second link member 13 constituting the link mechanism 11 are deformed to a bent state around the support shaft 14. Thus, since the warm feeling movable device 1 is movable, it is possible to make use of the space of the existing movable member 8. Moreover, since the warm feeling movable apparatus 1 moves by releasing the latching | locking of the contact part 15 of the link mechanism 11, and the latching | locking part 16a of the link stopper 16, the movable of the link mechanism 11 enough to remove this latching is sufficient. There should be enough space to secure the area. Furthermore, since only the link mechanism 11 that is a part of the movable member 8 of the temperature-sensitive movable device 1 needs to be moved, a large-scale device is also required for the link stopper 16 and the link stopper driving means 17 that move the link mechanism 11. Not needed. Therefore, it is possible to drive even with a slight force generated by the magnetic field of the small solenoid 20, and when the solenoid 20 is used, the link stopper driving means 17 itself can be made compact. Therefore, it is possible to provide a compact temperature-sensitive movable device 1 while taking advantage of the configuration of the conventional temperature fuse 5. Even if the fuse metal does not melt at a predetermined temperature due to deterioration of the fuse metal or the like, the temperature-sensitive movable device 1 can be driven by wiring so that an electrical signal output from another temperature detection device can be used. It becomes. Therefore, it is possible to ensure the driving reliability of the temperature-sensitive movable device 1.

  On the other hand, when the temperature-sensitive movable device 1 is moved only by the link stopper driving means 17, it is different from the case where the temperature fuse 5 is moved by reaching a predetermined temperature. When the temperature fuse 5 reaches a predetermined temperature, the movable pin 4 of the temperature fuse 5 and the fuse metal that welds the hollow conical cylinder 5a are melted, so that the movable pin 4 fixed to the hollow conical cylinder 5a is spring-loaded. 9 is inserted deeply into the hollow conical cylinder 5a. That is, the welding by the fuse metal melts, and the positional relationship between the movable pin 4 and the hollow conical cylinder 5a changes relatively. Therefore, in order to move the temperature-sensitive movable device 1 again by the movable operation of the movable pin 4 of the thermal fuse 5, the thermal fuse 5 is replaced. However, when the temperature-sensitive movable device 1 is moved only by the link stopper driving means 17, that is, when the link mechanism 11 is moved, the temperature-sensitive movable device 1 is moved. If it returns by this, the warm feeling movable apparatus 1 can be used as it is again. That is, it can be used as it is without replacement of components such as the thermal fuse 5.

FIG. 1 is a transverse cross-sectional view of a warm sensation movable device 1 of the present invention provided with a link mechanism return means 23. FIG. 2 is a top sectional view of FIG. Hereinafter, the link mechanism return means 23 will be described with reference to the accompanying drawings. The link mechanism return means 23 includes at least a return lever 25 provided with an operating portion 24 on one side and a link engaging portion 25a that engages with the bent position of the link mechanism 11 on the other side, and the return lever 25 as a link mechanism. 11 and a return spring 26 that is pulled back to the bent position.
The temperature-sensitive movable device 1 of the present invention provided with the link mechanism return means 23 is engaged with the link mechanism 11 when the link mechanism 11 is bent at the link engaging portion 25a that is engaged with the bent position of the link mechanism 11. To do. For this reason, the link mechanism return means 23 can return the link mechanism 11 by pulling the return lever 25 provided with the link mechanism 11 against the elastic force of the return spring 26.

More specifically, the link mechanism return means 23 has a return lever 25 provided with a link engaging portion 25a that engages with the bent position of the link mechanism 11. The return lever 25 engages with the place where the first link member 12 is located when the temperature-sensitive movable device 1 is moved by the link stopper driving means 17 and the link mechanism 11 is bent around the support shaft 14. A columnar or cylindrical shaft-shaped link engaging portion 25a, a return spring 26 for returning the return lever 25 to the bent position of the link mechanism 11 by being linked to the link engaging portion 25a, and the return spring 26 extended. When the link engaging portion 25a is connected to the link engaging portion 25a in the direction opposite to the direction in which the link engaging portion 25a is urged by the return spring 26, the opposite side where the connecting mechanism 25b is connected to the link engaging portion 25a. And an operation portion 24 for performing a return operation of the return lever 25 having the linear member 25c connected to the head.
The connecting mechanism 25b has a starting point and an ending point connected to the link engaging part 25a by a linear member, and the cylindrical frame 2 is inserted into one end of a plane formed by the connecting mechanism 25b and the link engaging part 25a. is doing. Since the cylindrical frame 2 is inserted into one end of the plane, the cylindrical frame 2 can be relatively moved to the other end of the plane by moving the return lever 25. It becomes.
The linear member 25c includes a hook portion f at the connecting portion between the connecting mechanism 25b and the linear member 25c. On the other hand, a hook projection ft connected to the hook part f is provided in a part of the connection mechanism 25b. For this reason, the hook portion f of the linear member 25c is connected to the hook protrusion ft of the connecting mechanism 25b, thereby being firmly connected. Even if the connecting mechanism 25b is pulled by the linear member 25c, the linear member 25c There is no fear that the connection with the connection mechanism 25b is released.
In FIG. 1, the return spring 26 is omitted.

  On the other hand, the first link member 12 of the link mechanism 11 has a columnar or cylindrical shaft-shaped link engagement portion 25 a of the link mechanism return means 23 engaged with the first upper end portion 12 a of the first link member 12. In addition, the first upper end portion 12a of the first link member 12 is provided with an engaged portion H that fits with the shaft shape of the link engaging portion 25a.

On the other hand, the operation of the movable member 8 is an operation of moving the protruding amount of the front end portion 6 of the main body portion 10 protruding from the cap 2b from a predetermined position determined by the thermal fuse 5 to a predetermined retracted position. In order to specify the amount of protrusion of the retracted position of the distal end portion 6 of the main body portion 10, the cylindrical frame 2 is provided with a protrusion t, and the second flange portion T 2 of the main body portion 10 is abutted against the protrusion t. By contacting, the movement of the main body portion 10 of the movable member 8 movable by the spring 9 is stopped.
Accordingly, the position of the movable member 8 after the operation is fixed, and the position of the temperature fuse 5 in the non-operating state is also determined. Therefore, the link mechanism 11 is moved by the link stopper driving means 17 and the support shaft 14 is centered. The positions of the first link member 12 and the second link member 13 that are bent in the direction are always constant.
For this reason, the standby position of the link engagement portion 25a of the link mechanism return means 23 can be set to a predetermined position, and the locus of the link engagement portion 25a that pulls back the first link member 12 of the link mechanism 11 is always constant. Thus, when the link mechanism 11 is bent, the link engaging portion 25a is always engaged with the engaged portion H of the first link member 12.
A guide G is formed in the case having the link mechanism return means 23 in order to create a trajectory of the link engaging portion 25a that is pulled back. When the operating portion 24 is pulled against the return spring 26, the guide G moves along the guide G. The link engaging part 25a to be moved moves to a position where the link stopper 16 and the contact part 15 are engaged with each other while engaging the engaged part H provided on the first upper end part 12a of the first link member 12. Thereafter, when the pulling of the operation portion 24 is stopped, the link engaging portion 25a is returned to the standby position by the return spring 26. The protrusion t may be provided on the inner side surface of the cylindrical frame 2 or may be formed by folding back at least a part of the side surface of the cylindrical frame 2 into the frame 2. By forming at least a part of the side surface in a folded manner inside the frame body 2, it is possible to reduce the manufacturing process and the manufacturing cost. In addition, it becomes possible to prevent that the movable member 8 falls out from the edge part 3 of the cylindrical frame 2 by the said 2nd collar part T2 being hold | maintained by the projection part t.

  Next, the operation of the link mechanism return means 23 will be described. FIG. 4 is a cross-sectional view before the link mechanism 11 is returned by the link mechanism return means 23. FIG. 5 is a top sectional view of FIG. FIG. 6 is a cross-sectional view showing a state where the link mechanism 11 is returned by the link mechanism return means 23. Specifically, when the temperature-sensitive movable device 1 is moved by the link stopper driving means 17, the first link member 12 draws a fixed path by moving the link mechanism 11, and the first link member The engaged portion H at the first upper end portion 12a engages with the link engaging portion 25a. More specifically, as shown in FIG. 5, in the upper cross-sectional view, the engaged portion H of the first link member 12 is linked by the first link member 12 and the second link member 13 spreading. Engages with part 25a. In this state, the link engaging portion 25 a is maintained at the bent position of the first link member 12 by the return spring 26.

  In this state, when the operation portion 24 of the return lever 25 is pulled, the link engaging portion 25a is opposed to the elastic force of the return spring 26 using the coupling mechanism 25b as a medium and is directed along the guide G toward the other end of the guide G. Move. Therefore, the first link member 12 engaged by the link engaging portion 25a also moves along the guide G to the position before the movable member 8 is movable. That is, the first link member 12 can be returned to the state before the link stopper driving means 17 is driven. As the first link member 12 returns, the second link member 13 also returns to the state before the link stopper driving means 17 is driven around the support shaft 14. Therefore, it is possible to return the link mechanism 11 to a substantially linear state.

On the other hand, the link stopper 16 unlocks the contact portion 15 of the first link member 12 when an electric signal is input to the link stopper driving means 17, and the link mechanism 11 moves to the operating position. In this case, when an electric signal is no longer input to the link stopper driving means 17, no magnetic field is generated in the solenoid 20 constituting the link stopper driving means 17. Thus, when the solenoid 20 is not energized, the suction shaft 21 is always urged in the protruding direction from the solenoid 20 by the solenoid spring. Further, since the link stopper 16 engaged with the suction shaft 21 is rotatable by the rotation shaft 19, the locking portion 16 a of the link stopper 16 is biased toward the link mechanism 11. Therefore, when the link stopper 16 is disengaged from the contact portion 15 of the first link member 12, the engaging portion 16 a of the link stopper 16 is returned to the position where it is engaged with the link mechanism 11.
Therefore, as described above, the first link member 12 of the link mechanism 11 is merely returned to a substantially linear position by pulling the link engaging portion 25a in the direction opposite to the return spring 26 against the elastic force of the return spring 26. Thus, the contact portion 15 of the first link member 12 and the locking portion 16a of the link stopper 16 are locked. That is, the link stopper 16 is urged clockwise, and the first link member 12 having the contact portion 15 that has been locked with the link stopper 16 also moves clockwise, whereby the first link member 12 is moved. Counters the clockwise biasing force of the link stopper 16 and returns to a position on a substantially straight line. Therefore, naturally, the contact portion 15 of the link stopper 16 and the first link member 12 can be locked again. At this time, by forming the corner of the first upper end portion 12a of the first link member 12 in an arc shape, the frictional resistance between the first link member 12 and the link stopper 16 in the return operation of the link mechanism 11 is reduced. Therefore, the return operation is performed smoothly.

  When the link mechanism 11 is returned by the link mechanism return means 23, when the return operation is completed, the link engagement portion 25a is pulled back by the return spring 26, and accordingly, the return lever 25 is also pulled back using the coupling mechanism 25b as a medium. It is. For this reason, the link engaging part 25a is returned to the bending position of the first upper end part 12a of the first link member 12. Therefore, the link engaging portion 25a is always returned to the bent position of the first upper end portion 12a of the first link member 12 by the return spring 26, whereby the temperature fuse 5 and the link stopper driving means 17 of the temperature sensitive movable device 1 are moved. Even in the case of operation, the link engaging portion 25a does not block the movement of the warm feeling movable device 1. That is, since the link mechanism return means 23 is always maintained at the bent position of the first link member 12 by the return spring 26, there is no need to return the return lever 25 to its original state. It will return to the state of. Therefore, it is possible to provide the temperature-sensitive movable device 1 that can be reliably moved again as long as the return operation is performed. Therefore, it is possible to provide the warm sensation movable device 1 that can be easily restored.

FIG. 7 shows a transverse cross-sectional view when the above-described temperature-sensitive movable device 1 of the present invention is used for the temperature-sensitive closing damper 28. The temperature-sensitive closing damper 28 is a damper 28a attached to a duct 27. A blade shaft 28b for driving the damper 28a, a drive means 29 for driving the blade shaft 28b to which the damper 28a is attached toward the closed position of the duct closing damper 28, and a drive means 29 at a position where the duct 27 is opened. And a lock portion 30 that holds the damper 28a against the driving force.
The temperature-sensitive movable device 1 of the present invention is attached to the duct 27 so that the temperature fuse 5 is located in the duct 27, and the tip portion 6 of the main body 10 of the temperature-sensitive movable device 1 is connected to the lock portion 30 of the driving means 29. When the link mechanism 11 or the thermal fuse 5 of the temperature-sensitive movable device 1 is actuated, the protruding amount of the tip portion 6 is reduced and the lock portion 30 is opened. For this reason, since the blade shaft 28b rotates by the action of the driving means 29, the damper 28a can close the duct 27.

More specifically, the duct closing damper 28 has drive means 29 for driving a rectangular damper 28 a disposed in the rectangular duct 27 toward the closed position of the duct closing damper 28. The drive means 29 includes a drive spring B for rotating the blade shaft 28b and a drive lever L for winding up the drive spring B, and one end of the drive lever L has a grip portion A for operating the drive means 29. And the lock part 30 which the front-end | tip part 6 of the main-body part 10 of the warm feeling movable apparatus 1 latches is arrange | positioned at the other end of this holding part A. As shown in FIG.
The drive spring B is attached between a fixed portion of the drive means 29 to the duct 27 and the drive lever L. Therefore, when the damper 28a is held in the open position by rotating the drive lever L against the spring force of the drive spring B and engaging the distal end portion 6 of the main body portion 10 of the warm sensation movable device 1 and the lock portion 30, Elastic force is stored in the drive spring B. Therefore, when the temperature-sensitive movable device 1 moves, the distal end portion 6 disengages from the lock portion 30 and releases the elastic force of the drive spring B, so that the drive lever L rotates together with the blade shaft 28b. The damper 28a is driven toward the closed position.

The lock portion 30 disposed at the other end of the drive lever L is positioned at an end of a lock lever 30a made of a plate material having an elastic force that is in close contact with the drive spring B side of the drive lever L. The lock lever 30a is driven. In a state where it is pressed against the drive lever L by the spring B, the drive lever L is movable together with the drive lever L.
When the lock portion 30 of the drive lever L is locked to the tip portion 6 of the warm sensation movable device 1 using the warm sensation movable device 1, the drive lever L is rotated and the damper 28 is rotated. Move from the closed position to the open position. And the lock part 30 installed in the other end part of the drive lever L is made to contact | abut with the front-end | tip part 6 of the warm feeling movable apparatus 1. FIG. The lock portion 30 is located at the side end located at the end of the lock lever 30a, and the lock contact portion 30b inclined toward the apex of the tip portion 6 is formed at the side end opposite to the lock portion 30. Is formed. For this reason, when the drive lever L is rotated by the gripping portion A, the lock lever 30a made of a plate material is curved as the lock contact portion 30b comes into contact with the tip portion 6 and the inclined surface climbs the tip portion 6. When the lock contact portion 30 b exceeds the tip portion 6, the curved lock lever 30 a is restored, and the tip portion 6 can be locked to the lock portion 30. Since this operation is performed simultaneously with the rotation of the blade shaft 28b, the damper 28a moves from the closed position to the open position, and the drive spring B is wound up to store the elastic force. Therefore, the temperature-sensitive closing damper 28 can be easily held at the open position by simply mounting the temperature-sensitive movable device 1 and rotating the drive lever L.

  In this way, by using the temperature-sensitive movable device 1 as the temperature-sensitive closing damper 28, the drive lever L is locked to the distal end portion 6 of the temperature-sensitive movable device 1 by the lock unit 30, thereby moving the temperature-sensitive movable device 1. When the member 8 is moved and the protruding amount of the tip portion 6 is reduced, the locking with the lock portion 30 is released. Therefore, the drive means 29 which drives the damper 28 arrange | positioned in the duct 27 toward a closed circuit position drives. Further, in this damper 28, the entire temperature fuse 5 is positioned in the duct 27, so that it is possible to reliably detect the high temperature in the fire. Therefore, when the temperature fuse 5 reaches a predetermined temperature, the temperature-sensitive movable device 1 moves, so that the protruding amount of the distal end portion 6 of the movable member 8 is reduced, and the locking with the lock portion 30 is prevented. Come off. Thereby, the drive means 29 which drives the damper 28 arrange | positioned in the duct 27 toward a closed circuit position drives. Therefore, installation and maintenance inspection can be greatly simplified. In addition, it is possible to provide a temperature-sensitive closing damper 28 that can be reliably closed even by a drive mechanism other than the thermal fuse 5. For this reason, it is possible to prevent the spread of fire and smoke.

  When the warm sensation movable device 1 of the present invention is used for the large damper 28 of the large duct, the driving force of the link stopper 16 is increased by using an electric motor for the link stopper driving means 17. Therefore, even when the link mechanism 11 of the warm feeling movable device 1 is enlarged, the warm feeling movable device 1 can be reliably moved. Accordingly, the large damper disposed in the large duct can be reliably operated by the sensing device such as temperature and smoke.

  In addition, when the temperature-sensitive movable device 1 is mounted on the temperature-sensitive closing damper 28, the temperature-sensitive movable device 1 is mounted on the cap 2 b of the cylindrical frame 2 by using a screw groove as a screw. The duct 27 can be screw-fitted. In this case, the temperature-sensitive movable device 1 can be firmly fixed to the duct 27 by being screwed into the duct 27. However, there is a possibility that the link stopper 16 and the contact portion 15 cannot be locked due to the positional relationship between the link stopper 16 and the contact portion 15 being shifted due to the tightening of the screw. Accordingly, the cylindrical frame 2 is fixed to the cap 2b by screw fitting, while the duct 27 and the temperature-sensitive movable device 1 are fitted to each other by non-screw type friction such as rubber packing. By using this, it is possible to provide the temperature-sensitive movable device 1 in which the link stopper 16 and the contact portion 15 can be easily positioned. That is, a screw groove is provided on the through hole side of the cap 2b, and the cap frame 2b is fitted to the cylindrical frame 2 by the screw groove. An elastic member that fits between the cap 2b of the temperature-sensitive movable device 1 to which the cylindrical frame 2 and the cap 2b are fixed and the cylindrical frame 2 by non-screw type friction such as rubber packing. By using this, it becomes possible to easily fit the temperature-sensitive movable device 1 to the temperature-sensitive closing damper 28. Therefore, it is possible to provide the warm sensation movable device 1 that is easy to mount and the positioning between the link stopper 16 and the contact portion 15 is easy.

  In addition, as an input of an electric signal which is a driving source of the link stopper driving means 17, an input of an electric signal generated when the smoke detector 18 detects smoke can be used. By using the electrical signal generated when smoke detector 18 detects smoke, if smoke is faster than fire, the smoke is detected immediately. It becomes possible to do. In addition, when an electrical signal generated when a chemical substance is detected by a chemical substance detector is used, it becomes possible to quickly detect a chemical substance harmful to a human body generated by a fire or the like. On the other hand, an electrical signal generated when the temperature sensor senses a predetermined temperature can be used. By using the temperature sensor, even if the temperature fuse 5 does not operate even when the temperature reaches a predetermined temperature due to deterioration of the fuse metal of the temperature fuse 5, the temperature sensor is activated, and the temperature-sensitive movable device 1 is moved. The warm feeling movable device 1 can be moved reliably. Accordingly, it is possible to provide a temperature-sensitive movable device 1 driven by an electric signal, and sense other than the temperature by using a sensor such as a smoke sensor or a chemical substance sensor for the input of the electric signal. Thus, it is possible to provide the temperature-sensitive movable device 1 that is movable. Therefore, it is possible to provide the temperature-sensitive closing damper 28 using the temperature-sensitive movable device 1 that can be driven in association with detection of another state in addition to detecting high temperature.
