Description

  The present invention relates to a locking mechanism for a sealing device provided with a moving partition that may be referred to as a moving wall.

  Conventionally, moving partitions are often installed in large spaces such as banquet halls and multipurpose halls in order to partition and use the spaces. And when this movement partition is moved and arranged so as to partition the space, the partition space (or partition wall body) is either upper, lower end, or one of the ends in order to airtightly block the partitioned spaces. A sealing device is provided at the part so as to be freely movable in and out of the partition panel.

  The sealing device can move freely with respect to the partition panel. When the panel is moved or stored, the sealing member is accommodated inside the panel so as not to obstruct the movement. When placed in a predetermined position, the sealing member protrudes and is brought into pressure contact with the floor surface or ceiling surface, thereby sealing (sealing) a gap generated between the panel end and the floor surface or ceiling surface. Because.

The above-described intrusion-type sealing device is already well known from Patent Documents 1 to 6 and the like, but if it is already described, it has approximately the following configuration and functions.
That is, a seal member having a length substantially equal to the front width of the partition panel is arranged so as to be able to appear and retract (or move up and down in the vertical direction), for example, at the lower end of the panel, and the seal member is folded and linked. By supporting with a support link using a spring and a spring, the seal member advances and retreats in the vertical direction so as to be immersed in the panel or advanced outside the panel.

  Here, the folding link mechanism is always urged to the folding side by an intervening tension spring, and therefore, the seal member is kept immersed inside the panel unless an external force acts on the link mechanism. However, when an external force acts on the link mechanism on the side where the link extends, the seal member is formed to advance from the inside of the panel toward the floor (or ceiling) by the extension operation of the link mechanism. The link mechanism is provided with an operating rod for extending and folding the mechanism.

The advancing position of the seal member (pressure contact state on the floor surface or ceiling surface) must be locked against the spring force of the tension spring to return the seal member into the panel. In the technology, there is no lock mechanism that has a simple structure but can perform a reliable lock-on / lock-off operation (also referred to as a lock / unlock operation).
Japanese Examined Patent Publication No. 52-43344 Japanese Patent No. 3583891 Japanese Patent No. 3046559 Japanese Patent No. 2782155 Japanese Utility Model Publication No. 60-94588 No. 7-6468

  Accordingly, an object of the present invention is to provide a locking mechanism for a locking device in a moving partition seal device, which has a simple structure and performs a reliable locking and unlocking operation.

The first configuration of the locking mechanism of the present invention, which has been made for the purpose of solving the above-described problems, includes a folding link mechanism that is connected to a seal member that protrudes and protrudes from an end of a moving partition panel, and an operating rod that is connected to the link mechanism. In the moving partition seal device in which the seal member is advanced and retracted with respect to the panel end, by providing a hole provided with a lock bar on one end side, for example, the rear end side of the operating rod. Provided in a posture inclined through the rod in the retracting direction of the rod, and the operation rod is prevented from retreating when the hole of the lock bar tilted in the posture and the operation rod meet, while the posture of the lock bar is upright Thus, the backward movement of the operating rod is allowed.
In this lock mechanism, an operation member that erects the tilting posture of the lock bar is connected to the lock bar via a lock release member, and the operation member is provided so that it can be operated from the outside of the moving partition panel. It's easy to do.

  A second configuration of the locking mechanism of the present invention that can solve the above-described problem is that, in the moving partition seal device having the same configuration as described above, a rack-like stop tooth is provided on one end side of the operating rod, for example, the tip end side. A latch member having a locking tooth that prevents the rod from moving backward when engaged with the stop tooth and allows the rod to move backward when the engagement is released; It may be characterized by being provided so as to face the surface.

  Even in the second locking mechanism of the present invention, the operation member for releasing the engagement between the latching teeth of the latch member and the rack-like stop teeth can be linked to the latch member, and the operation member can be operated from the outside of the moving partition panel. By providing in this way, this operation member can be operated from the exterior of a movement partition panel.

In the sealing device to which the second invention locking mechanism is applied, the spring provided so as to always urge the folding link mechanism to the folding side is always retracted by the spring force through the link mechanism. The rod was urged so as to face toward. Thus, the rear end side of the operating rod is held in a state exposed to the outside from the side surface of the partition panel.
Since the folding link mechanism is always held in the folding side by the action of the spring force, the seal member connected to and supported by the link mechanism is always retracted from the end of the partition panel to the inside thereof. It is held in an (immersive) state.

  When the operating rod in the retracted state is pushed by an external force (for example, by human force) (pushing into the inner side of the partition panel), the folding link mechanism is extended against the spring force and connected to the link mechanism. The seal member advances from the end of the partition panel toward the outside and is pressed against the floor surface (or ceiling surface) to close the gap between the panel end surface and the floor (or ceiling) almost airtightly.

  When the rod is pushed (advanced), the locking member having a latching tooth of the latch member and a locking member having a rack-like stop tooth move together with the advancing rod, so that the locking member moves forward. In the stopped position, the locking tooth meshes with the stop tooth facing the locking tooth, thereby preventing the operating rod from retreating by the spring force and being held in that position.

  In the present invention, the folding link mechanism connected to the seal member protruding and retracting from the end of the moving partition panel is advanced and retracted with respect to the panel end by moving the operating rod connected to the link mechanism forward and backward. In the moving partition sealing device thus configured, the one end side of the actuating rod, for example, the rear end side, is provided with a posture in which a lock bar is provided in the rod and is inclined in the retracting direction of the rod. Since the tilted hole of the lock bar and the actuating rod meet each other, the actuating rod is prevented from retracting, while the lock bar is kept upright to allow the actuating rod to recede. Although it is very simple, the advancing state of the seal member can be securely held in the locked / unlocked state.

Next, an embodiment of the locking mechanism of the present invention will be described with reference to the drawings.
In the accompanying drawings, FIG. 1 is a front view showing the inside of the vicinity of the lower end of the moving partition panel in which the sealing device having the second example of the locking mechanism of the present invention is housed, and FIG. 2 is taken out from the panel of FIG. 3 and FIG. 4 are enlarged front views of a portion of the locking mechanism of the present invention disposed with respect to the sealing device in FIG. 1, FIG. 3 is when locked, and FIG. FIG. 5 is a front view showing a main part of another example of the operation portion of the lock mechanism, FIGS. 6 and 7 are a first example of the lock mechanism of the present invention, and FIG. FIG. 7 is a front view, partly in section, showing the lock mechanism when unlocking.

  In this specification, first, a second example of the locking mechanism of the present invention will be described with reference to FIGS. In FIG. 1, reference numeral 1 denotes a panel having a substantially rectangular shape in front view forming a moving partition MW. The schematic structure is, for example, left and right vertical frame members 1a and 1b arranged in a frame shape on four sides, and above and below. The outer frame material 1c is stretched around the front and rear surfaces of the horizontal frame material 1d. Although such a panel 1 is not illustrated, the upper end side of the panel is suspended and supported by a traveling wheel (not shown) mounted on a rail (rail) provided on the ceiling, and is moved in a hanging door type. It is formed in the moving partition MW.

  A sealing device S for closing a gap G formed between the floor F and the lower end of the panel 1 is accommodated in the lower end of the panel 1 as illustrated in FIG. It is installed and provided. Next, the sealing device S will be described.

  1 and 2, the sealing device S is constructed such that a base frame 2 having a reverse concave shape in cross section is fixedly installed inside a horizontal frame member 1d on the lower end side of the panel 1, and the left and right ends of the base frame 2 are fixed. On the side, plate-like bearing members 3 and 4 are provided so as to cross the frame 2.

  The left and right bearing members 3 and 4 in the base frame 2 shown in FIGS. 1 and 2 extend through the shaft holes so as to be able to advance and retract. The actuating rod 5 is provided so that the left end side 5a (also referred to as the rear end side 5a of the rod 5) in FIG. 1 protrudes appropriately from the side surface of the panel 1 to the outside, and the right end side 5b of the rod 5 is provided. (Also referred to as the front end side 5b of the rod 5) is slightly cut out from the bearing member 4 and fits inside the panel 1.

  A rack-like lock member 6 having rack-like stop teeth 6a formed on the lower surface is connected to the right end side 5b (also referred to as the front end side 5b) of the rod 5 via a joint 6b. The lock member 6 includes two guide pins 6c that are horizontal in a direction orthogonal to the length direction. The two guide pins 6c are supported by two horizontal long hole guides 7a provided on the bracket 7 for the lock mechanism attached to the right end portion of the base frame 2 to ensure the horizontal movement of the lock member 6. is doing. 7b and 7c are plate-like members provided on the left and right sides of the bracket, and the member 7c on the right side of the drawing is provided with a shaft hole 7d through which an operation member 16 described later is passed.

  Near the left and right ends of the actuating rod 5, links 8a and 9a having a downward slope in FIGS. 1 and 2 are pivotally connected to the rod 5 at their respective upper ends (also referred to as pivot points P1). The seal member base 10 disposed on the upper surface side of the seal member 11 is pivotally connected (also referred to as a pivot point P2) to the lower ends of the links 8a and 9a. The links 8a and 9a are provided in an inclined parallel posture.

  At the midpoint of each of the links 8a and 9a, the lower ends of the links 8b and 9b, which are approximately half the length of the links 8a and 9a with the inclination (posture) crossing the links 8a and 9a, respectively, pivot. The upper ends of the links 8b and 9b are pivoted P4 (also referred to as pivot point P4) to the stationary base frame 2 while being connected (also referred to as pivot point P3). The tension springs 8c and 9c are stretched between the pivot points P2 and P4 of the link, respectively, and a tensile force is always provided between the pivot points P2 and P4. Yes. These members 8a to 8c and 9a to 9c form folding link mechanisms 8 and 9 that act so as to always lift the seal member base 10 upward.

  Thus, when the operating rod 5 protruding from the right end surface of the panel 1 is pushed to the right in FIGS. 1 and 2, the rod 5 is moved to the right with the pivot point P1 of the links 8a and 9a. Move to. When the pivot point P1 of the links 8a and 9a moves to the right, the links 8a and 9a are restrained at the pivot point P3 by the non-moving links 8b and 9b. The posture is deformed. When the links 8a and 9a rise (stand on the vertical side), the clearance between the pivot points P2 and P4 expands (extends) against the spring force of the springs 8c and 9c. This enlarged deformation moves the seal member base 10 downward.

  Even if the seal member base 10 is displaced (moved) downward in this way, the tensile force of the springs 8c and 9c is always acting between the pivot points P2 and P4 in the link mechanisms 8 and 9. When the pushing force of the rod 5 is released, that is, when the hand is released, the link mechanisms 8 and 9 return to the original folded posture.

  Therefore, in the present invention, the actuating rod 5 is pushed to the right in the figure to deform the link mechanisms 8 and 9 (the gap between the pivot points P2 and P4 is widened), and the seal member base 10 is moved downward to adhere to the floor F. In order to maintain (or maintain) this state, a lock mechanism L connected to the rod 5 is provided. Next, the lock mechanism L will be described with reference to FIGS.

  The lock mechanism L of the present invention uses the lock member 6 having the rack-like stop teeth 6a described above, and locks the lock member 6 that has advanced to the right in the figure simultaneously by the pushing movement of the operating rod 5. The position is held (set to a locked state), and the locked state can be released by an external operation.

  A latch member 12 having a locking tooth 12a that engages with or disengages from a rack-like stop tooth 6a is provided on the bracket 7 that supports the locking member 6 so that it can be moved forward and backward by the pin 6c. It is attached to a rocking lever 13 that is coaxial with 12 and is rotatably provided by a shaft 13a. Here, three locking teeth 12a of the latch member 12 are provided on the rotation circumference of the member, but how many stop teeth 12a are provided is arbitrary.

  Two stopper projections 12b and 12c that act as stoppers for restricting the rotation angle of the latch member 12 are provided on the rotation circumference of the latch member 12 on the substantially opposite side of the locking tooth 12a with an appropriate angular separation.

  In addition, the latch member 12 is provided with a spring 14 that continuously pulls the latch member 12 counterclockwise, and when the latch member 12 is angularly rotated clockwise, the latch member 12 is returned to the restoring position by the spring force. It is supposed to be. 12d is a spring receiver provided on the rotation circumference of the abutting latch member 12, 14a is a spring receiver provided on the wall of the bracket 7, and the spring 14 is stretched between the spring receivers 12d and 14a and is attached to the latch member 12. The counterclockwise force is constantly applied. The tensile force of the spring 14 also reaches the swing lever 13 that is coaxial with the latch member 12.

  On the other hand, on the wall of the bracket 7 positioned between the two stopper protrusions 12b and 12c, a stopper pin 15 is provided which abuts against the rotating stopper protrusion 12b or 12c and restricts the rotation of the latch member 12 up to that position. It is installed.

A tip end side of an operation rod 16 as an operation member provided by being inserted through a hole of a right plate member 7 c provided on the bracket 7 is connected to the swing lever 13 via a pivot shaft 17. The pivot shaft 17 has a guide hole 13b formed by a vertically long slot provided below the actuating lever 13, and a second guide hole formed by a horizontally long slot provided in the wall of the bracket 7 in a direction crossing the guide hole 13b. 7d is pivotally supported so that it can slide in both holes.
The rear end 16a (right side of the figure) of the operation rod 16 protrudes outside the bracket 7 of the lock mechanism L and is slightly exposed from the right side surface (the vertical frame member 1b side) of the partition panel 1 (see FIG. 1).

Next, an operation example of the lock mechanism L of the present invention configured as described above will be described.
When the moving partition MV (the panel 1) travels to the right in the drawing and the panel 1 comes into contact with the dead end wall or the rear end surface of the immediately preceding panel, the rear end side 5a (left end side 5a) of the actuating rod 5 Is pushed by the rear end face of the wall or the preceding panel, the operating rod 5 moves to the right in the figure.

  The right movement of the actuating rod 5 simultaneously deforms the links 8a and 9a of the folding link mechanisms 8 and 9 to stand up, and the base 10 connected to the link mechanisms 8 and 9 by the standing operation of the links 8a and 9a. The seal member 11 attached to the floor F is extruded to the floor F side and pressed against the floor F. As a result, the gap G existing between the lower surfaces of the panel 1 is filled with the seal member 11.

  The right movement of the actuating rod that lowers the seal member 11 causes the lock member 6 with rack-like stop teeth 6a connected to the tip 5b of the rod 5 to simultaneously move right. In the latch member 12 having the locking teeth 12a meshing with the stop teeth 6a of the lock member 6, the three teeth 12a are slightly offset to the right with respect to the movement direction (right movement) of the lock member 6. The right movement of the lock member 6 is, for example, an operation in which the latch member 12 returns to the original state by the spring force of the spring 14 when the latch member 12 rotates clockwise by a pitch of one tooth (ratchet operation). ) Is allowed.

  However, when the lock member 6 reaches the right moving end (the end where the actuating rod 5 is pushed) and stops, the side where the links 8a and 9a are tilted from the standing side by the tensile force of the springs 8c and 9c of the link mechanisms 8 and 9. Therefore, the actuating rod 5 is urged to the left side, and the urging force is also transmitted to the lock member 6 connected to the rod 5.

  When the tensile force of the springs 8c, 9c of the link mechanisms 8, 9 is transmitted to the lock member 6 and tries to move the member 6 to the left, the latch is engaged with the stop teeth 6a of the lock member 6 by the locking teeth 12a. The member 12 tries to rotate counterclockwise, but the rotation is blocked by the action of the stopper projection 12b and the stopper pin 15 provided on the latch member 12, and is connected to the lock member 6 and the member 6. The operating rod 5 that is present cannot move to the left. That is, the actuating rod 5 is locked on, and the seal member 11 can be pushed out and kept in pressure contact with the floor F. This lock-on state is not released by external vibration or the like because the latch member 12 is always urged counterclockwise by the spring 14 via the swing lever 13.

  The lock member 6 in the locked state is unlocked and the lock member 6 is moved to the left, that is, the lock is released and the operating rod 5 is moved to the left (this also raises the seal member 11). To this end, the operating rod 16 is pushed leftward on the rear end 16a of the panel 1 so that the swing lever 13 swings (rotates angularly) clockwise.

  When the oscillating lever 13 oscillates (angular rotation), the latch member 12 coaxial with the lever 13 rotates angularly in the clockwise direction, and the stop teeth 12a and the locking teeth 6a of the lock member 6 mesh with each other. Therefore, the lock member 6 and the operating rod 5 are in an operation free state.

  When the operating rod 5 becomes operation free, the link mechanism is folded by the spring force of the springs 8c and 9c of the link mechanisms 8 and 9, so that the seal member 11 connected to the links 8a and 9a via the base 10 is used. Will return to the original position.

In the locking mechanism L of the present invention described above, the locked state is released by the pushing operation of the operating rod 16, but in the present invention, the configuration of the operating unit shown in FIG. 5 can be adopted.
In the previous embodiment, the rear end portion 16a of the operation rod 16 projected from the surface of the right end 1b of the panel 1 is pushed into the panel inside by hand. The configuration shown in FIG. That is, in the configuration of FIG. 5, the rear end portion 16 a of the operation rod 16 is provided with a length accommodated in the panel 1, and the rear end portion 16 a is moved by the operation of the operation pedal 18. I moved it to the left. In FIG. 5, 18a is a mounting shaft with a return spring of the pedal 18, 18b is a rod pressing surface of the pedal 18, and 18c is a tread surface of the pedal. With this configuration, when the tread surface 18c is stepped down with a foot, the rod pressing surface 18b pushes the end of the operating rod 16 to move the rod to the left, so that the same effect as the previous example can be obtained.

  In the locking mechanism L of the present invention described above, the latch member 12 provided coaxially with the rocking lever 13 is provided with a ratchet gear (or a ratchet wheel) (here, only clockwise rotation is permitted and counterclockwise). In the direction of rotation, the gear teeth function as locking teeth). When the ratchet gear (or the claw wheel) is provided coaxially or coaxially with the swing lever 13, the stopper pin 15 and the stopper protrusions 12b and 12c are not required. The spring 14 may be used as a return spring for the swing lever 13. Further, although the lock mechanism L in the above example is provided near the front end side 5b of the operating rod 5, the lock mechanism L of the present invention can be disposed in the vicinity of the rear end side 5a of the operating rod 5.

  In the lock mechanism L of the second example of the present invention described with reference to FIGS. 1 to 5, the actuating rod 5 is moved (advanced) to the right in FIGS. The components of the lock mechanism L including the lock member 6 are arranged at the end of the advance side (the right end side in the figure). However, in the present invention, the operating rod 5 is moved leftward to lower the seal member 11. The lock mechanism can be connected to the seal device S including the actuating rod 5 and the link mechanisms 8 and 9 having a structure. This point will be described with reference to FIGS. 6 and 7, the same reference numerals are used for the same members and parts as those in FIGS.

  6 and 7 show a lock mechanism L2 of the seal device S of the type in which the actuating rod 5 is pushed to the left in the figure outside the right end surface of the panel 1 in order to lower the seal member 11. In the vicinity of the right end portion 5 (in the vicinity of the right end side 5b in FIGS. 6 and 7), the lock mechanism L2 of the first example of the present invention having a configuration different from the above example (see FIGS. 3 to 5) is disposed. An example is shown. In the sealing device S to which the lock mechanism L2 of FIGS. 6 and 7 is applied, the right end side 5b of the actuating rod 5 is exposed to the outside from the right end surface of the panel 1, so that the seal member 11 is lowered during sealing. When the panel 1 reaches the moving end (left direction in FIG. 1) and stops, the right end portion 5b of the actuating rod 5 is moved to the left in the drawing at the front end surface of the next panel 1 that has moved. It is done by pushing in.

  The locking mechanisms L and L2 of the present invention both move the operating rod 5 to the right or left so as to push the sealing member 11 against the floor (ceiling surface) so as to push it into the panel. In order to hold the seal member 11 pressed against the floor surface F by the action of the lock mechanism in its position by the action of the lock mechanism and to return the seal member 11 to the original state, it is common in that the lock mechanism is unlocked. ing. In the type in which the actuating rod 5 moves to the left in the figure at the time of sealing, the link mechanisms 9 and 10 interposed between the actuating rod 5 and the seal member base 10 are arranged in directions symmetrical to those in FIGS. become.

  The locking mechanism L2 of the first example according to the present invention illustrated in FIGS. 6 and 7 is also provided in association with the distal end side 5b of the actuating rod 5 located near the right end in the panel 1 of FIG. Yes. However, in FIGS. 6 and 7, the advancement direction of the operating rod 5 at the time of sealing is leftward.

  6 and 7, 21 is extrapolated to the front side (right side of FIGS. 6 and 7) of the bearing member 4 of the operating rod 5, and the tip (left side in the figure) is received by the bearing member 4. The coil spring 22 is in contact with or coupled to the right end of the spring 21 and is loosely fitted into the actuating rod 5 in the upper hole 22a formed larger than the outer diameter of this part (lock part) of the actuating rod 5. In this lock bar, the lock bar 22 with a hole is connected to an unlocking member 24 provided in a case 23 of a lock mechanism L2 described below. Here, the release member 24 has a substantially U-shaped cross section with a width that allows the lower end side of the lock bar 22 to be loosely inserted, and two pins 24a and 24b that cross the U-shaped groove are installed near both ends. Yes.

  The case 23 is formed in a substantially mouth-shaped cylindrical shape (the top and the ground are open) that is horizontally long in plan view, and is attached to the standing wall of the base frame 2 in the vicinity of the lock bar 22, and the lock bar 22 is attached to the case 23 It is positioned to be housed inside 23.

  The lock bar 22 accommodated in the case 23 is between the pins 24a and 24b provided in the release member 24 supported in a manner sandwiched between the two guide pins 25a and 25b provided inside the case 23, And between the pins 25a and 24b, here, the middle part on the front side abuts on the pin 25a, and the lower part of the bar 22 is positioned near the pin 24b and connected to the release member 24. Has been.

  The unlocking member 24 arranged inside the case 23 in a state sandwiched between the guide pins 25a and 25b has an upper end portion (pin 24a side) with an intermediate portion near the side end portion of the case 23 and a shaft 26a. The upper end of the supported unlocking bead member 26 is connected by being pivotally connected by the pin 24a.

  The lock bar 22 constantly receives the force that the back side of the hole 22a is pushed toward the right end side 5b of the actuating rod 5 by the spring 21, while the lower side of the hole 22a of the bar 22 (intermediate part of the lock bar 22) Since the front surface of the bar 22 is supported by the guide pins 25a, it is held in the inclined posture shown in FIG.

  Due to the tilted posture of the lock bar 22, the operating rod 5 is freely movable (pushable) to the left in FIG. 6, but to the right in FIG. Because it is in a state of hitting, it is impossible to move, that is, locked state.

  In order to release this locked state, the pedal member 26 protruding from the right side surface of the case 23 is stepped down, and the upper half side of the pedal member 26 is angularly rotated counterclockwise about the shaft 26a (FIG. 7). reference).

  When the upper half side of the pedal member 26 is angularly rotated in the counterclockwise direction, the upper end side of the release member 24 connected by the pin 24a is pulled up to the upper right of the case 23 according to the angular rotation.

  When the release member 24 is pulled up as described above, the lower back side of the lock bar 22 is pushed rightward in FIG. 7 by the pin 24b of the member 24. When the pushing force acts on the back surface of the lock bar 22, the middle portion of the front surface side of the bar 22 is in contact with the guide pin 25a, so that the upper half side of the bar 22 resists the spring force of the spring 21. Then, it is angularly rotated counterclockwise around the pin 25a.

  When the upper half side of the lock bar 22 is rotated counterclockwise around the pin 25a, the inclined posture of the bar 22 (see FIG. 6) changes to the standing (or upright) posture of FIG. The actuating rod 5 is in a state where it can freely move through the hole 22a of the lock bar 22. That is, the lock is released.

  When the force of stepping on the pedal member 26 is released, the lock bar 22, the release member 24, and the pedal member 26 are returned to their original positions (see FIG. 6) by the spring force of the spring 21.

  As described above, the lock mechanism L2 of the first example of the present invention shown in FIGS. 6 and 7 pushes the operating rod 5 by the action of the lock bar 22 (moves leftward in FIGS. 6 and 7). The operation of causing the seal member 11 to advance) is free, but when the rod 5 that is pushed in returns to its original position by the spring force of the springs 8c and 9c provided in the seal device S, the tilted posture of the lock bar 22 Thus, the return operation of the rod 5 is locked by the hole 22a of the lock bar 22, so that the operating rod 5 is locked at the position where it is pushed to the left and held there.

  To release the locked state, as described above, the pedal member 26 is depressed to change the posture of the lock bar 22 from the inclined posture (FIG. 6) to the vertical posture (FIG. 7). The above-described lock mechanism L2 of the present invention is provided in the vicinity of the distal end side 5b of the operating rod 5, but in the present invention, the lock mechanism L2 may be provided in the vicinity of the rear end side 5a of the operating rod 5.

  The above-described lock mechanism L2 of the present invention is achieved by pushing the right end portion of the actuating rod 5 to the left by the front end surface of the next panel 1 where the lowering of the seal member 11 of the seal device S moves. That is, since the seal member 11 is lowered in the panel 1 that has been moved and stopped, the seal member 11 is completely at the floor surface F as compared with the type in which the panel 1 reaches the end of movement while the seal member 11 is lowered. There is no movement while rubbing. As a result, premature wear of the seal member 11 can be prevented.

  The present invention is as described above, and the folding rod mechanism connected to the seal member protruding and retracting from the end of the moving partition panel is moved forward and backward so that the seal member is moved forward and backward. In the sealing device for the moving partition which is advanced and retracted with respect to the panel end, the one end side of the operating rod, for example, the rear end side, and a hole provided in the lock bar is passed through the rod and tilted in the retracting direction of the rod. It is provided in a posture, and the operation rod is prevented from retreating when the hole of the lock bar inclined in the posture and the operation rod meet each other, while the posture of the lock bar is kept upright to allow the operation rod to retreat. Since the lock mechanism of the sealing device is constructed in this way, it can be easily manufactured because of its extremely simple structure, and therefore it can be moved at low cost. It is possible to provide a locking mechanism of the sealing device in the partition.
