  By the way, in the conventional entrance / exit blocking device for a parking space described above, since the blocking body and the raising / lowering means for raising and lowering the blocking body have to be buried in the ground, the installation work of the entrance / exit blocking device is laborious and costly. It took a long time.

  For this reason, the device for making installation work of an entrance-exit blocker easier is calculated | required.

  An object of the present invention is to provide a parking space entrance / exit blocking device and a method thereof that make installation work easier.

  An entrance / exit blocking device for a parking space according to the present invention includes an exit block that can be raised and lowered for blocking an entrance / exit of the parking space, and an elevating means for raising and lowering the block body. In the above, it is arrange | positioned above the parking surface of the said parking space.

  In the present invention, the parking space entrance / exit blocking device is disposed above the parking surface, not below the parking surface of the parking space.

  That is, in the present invention, there is no need to embed a parking space entrance / exit blocking device under the parking surface as in the prior art.

  For this reason, according to this invention, the installation operation | work of the entrance-and-exit interruption | blocking apparatus of a parking space can be performed more easily.

  In the present invention, the form and structure of the lifting means for lifting and lowering the blocking body may be arbitrary, and an example of the lifting means has a winding shaft.

  In the present invention, the type and structure of the blocking body may be arbitrary. An example of the blocking body in the case where the elevating means has the winding shaft as described above is a member to be wound that is fed and wound by the winding shaft, and disposed at the lower part of the member to be wound. It is comprised including a horizontally long member.

  Here, the laterally long member is a member that is long in the lateral direction (left and right direction that is a direction orthogonal to the ascending / descending direction), for example, a rod-shaped member (which may be hollow or solid), A shaped member (in other words, a panel shaped member) or the like may be used. Further, one horizontally long member may be arranged below the member to be wound, or a plurality of horizontally long members may be arranged in the ascending / descending direction.

  In the present invention, when the lifting / lowering means has the winding shaft as described above, it may be provided with blocking state holding means for holding the blocking state of the entrance / exit by the blocking body. Also good.

  According to the former case, the shut-off state of the entrance / exit by the shut-off body is more reliably maintained.

  In the present invention, as described above, the elevating means has a take-up shaft, and the shield is drawn out and taken up by the take-up shaft, and a lower portion of the take-up member. In this case, the form and structure of the member to be wound may be arbitrary as long as they are fed out and wound by the winding shaft.

  A first example of the member to be wound is a string-like member. In this first example, the member to be wound may be constituted by one string-like member or may be constituted by a plurality of string-like members.

  In the latter case, each of these string-like members may be arranged apart from each other in the width direction of the doorway, and each of these string-like members may be extended in the vertical direction from the winding shaft to the horizontally long member. .

  According to this, when a plurality of string-like members are wound on the take-up shaft, these string-like members are wound on the take-up shaft without overlapping with each other in the radial direction of the take-up shaft. .

  Moreover, in the latter case (in the case of being composed of a plurality of string-like members), the arrangement position of the upper end portion and the arrangement position of the lower end portion of each string-like member is the axial direction of the winding shaft. You may make it slip to.

  According to this, when a plurality of string-like members are wound around the take-up shaft, these string-like members are wound up spirally around the take-up shaft without overlapping in the radial direction of the take-up shaft. Can be.

  For this reason, when a plurality of string-like members are wound on the take-up shaft, the winding diameter of these string-like members can be made small.

  Moreover, the 2nd example of the to-be-winded member mentioned above is a sheet-like member. Here, the sheet-like member may be composed of a single sheet or a plurality of sheets.

  In the latter case, the respective sheet-like members may be arranged apart from each other in the width direction of the doorway, and the respective sheet-like members are sewn, bonded, and welded in the width direction of the doorway. Also good.

  In addition, it is preferable to form a sheet-like member with the material which has waterproofness and durability.

  The sheet-like member includes a mesh-like member.

  In the present invention, as described above, the blocking body is configured to include a member to be wound that is drawn out and wound by the winding shaft, and a horizontally long member that is disposed below the member to be wound. In the case of a thing, it is preferable that the height position of the horizontally long member in a state where the doorway is blocked by the blocking body is a height position that hinders entry of a vehicle or a person into the parking space.

  In the present invention, as described above, when the blocking state holding means for holding the blocking state of the entrance / exit by the blocking body is provided, the type and structure of the blocking state holding means may be arbitrary.

  The blocking state holding means includes, for example, a locking member connected to the horizontally long member by a connecting member, and a locked member provided on the parking surface and locked by the locking member. It may be configured to include a locking member provided on the parking surface, and a locked member that is connected to the horizontally long member by the connecting member and is locked by the locking member. Good.

  Here, in the first example of the locking member and the locked member, one of the locking member and the locked member includes a magnet, and the other includes a magnetic body that is attracted to the magnet. It is composed of. Further, in the second example of the locking member and the locked member, one of the locking member and the locked member is a hook member, and the other is a pin member or ring that can be locked by the hook member. Member.

  In the present invention, when the lifting / lowering means has the winding shaft as described above, the winding shaft rotates inside the winding shaft when the member to be wound is unwound from the winding shaft. A return spring in which the spring force is accumulated on the shaft may be arranged, and the spring force of the return spring may always be equal to or greater than the dead weight of the blocking body.

  When the spring force of the return spring is always the same as the weight of the blocking body, that is, when the spring force of the return spring and the weight of the blocking body are in an equilibrium state, the above-described blocking state holding means is not necessarily Further, it is not necessary, and the force for raising the blocking body in the state where the doorway is blocked (the force for lifting operation) can be made lighter.

  Also, when the spring force of the return spring is always greater than the dead weight of the shut-off body, the shut-off state holding means is indispensable, but the force for raising the shut-off body in the state where the doorway is shut off (the force for lifting operation) ) Is not necessary, and the blocker is raised by the spring force of the accumulated return spring.

  In the present invention, when the lifting means has the winding shaft as described above (as described above, a return spring is disposed inside the winding shaft, and the spring force of this return spring is always applied to the weight of the shut-off body. In other words, the lifting / lowering means may or may not be equipped with a speed reduction means for reducing the descending speed of the blocking body.

  According to the former case, the driver of the vehicle can take the vehicle out of the parking space with a margin after starting the lowering of the blocking body.

  In the former case, a return spring is arranged inside the take-up shaft so that the spring force is accumulated by the rotating take-up shaft when the member to be wound is drawn from the take-up shaft. The spring force of the spring may always be smaller than the dead weight of the blocking body. In this case, the non-blocking state holding means for holding the non-blocking state in which the member to be wound of the blocking body is wound around the winding shaft, and non-blocking by the non-blocking state holding means The non-blocking state holding state releasing means for releasing the holding state of the state is provided, and the non-blocking state holding state releasing unit releases the non-blocking state holding state by the non-blocking state holding state releasing unit. May start descending. That is, when the non-blocking state holding unit releases the non-blocking state holding state by the non-blocking state holding state canceling unit, the blocking body starts to descend (in other words, descending) due to its own weight.

  Note that the non-blocking state holding state releasing means may be a mechanical release of the non-blocking state holding state by the non-blocking state holding means, or an electric release. Further, the non-blocking state holding state canceling unit may manually cancel the non-blocking state holding state by the non-blocking state holding unit, or may automatically cancel it.

  In the present invention described above, a mark indicating that entry into the parking space is prohibited may or may not be attached to the entrance / exit side portion of the blocking body.

  The parking space entrance / exit blocking method according to the present invention is a parking space entrance / exit blocking method for blocking an entrance / exit of a parking space in which a blocking body and lifting means for raising and lowering the blocking body are arranged above the parking surface. And when the vehicle is stored in the parking space, the blocking body is disposed above the vehicle, and when the vehicle leaves the parking space, the blocking body is lowered while being decelerated, After the vehicle exits the doorway, the doorway is blocked by the blocking body.

  As described above, in the present invention, the blocking body and the lifting means for moving the blocking body up and down are disposed above the parking surface.

  That is, according to the present invention, there is no need to embed a blocking body and a lifting means for lifting and lowering the blocking body under the parking surface as in the prior art.

  For this reason, according to the present invention, it is possible to more easily perform the installation work of the blocking body and the lifting means for lifting and lowering the blocking body.

  Further, in the present invention, when the vehicle is stored in the parking space, the blocking body is disposed above the vehicle, and when the vehicle leaves the parking space, the blocking body is lowered while being decelerated, and the vehicle opens and closes the doorway. After exiting, the entrance / exit is blocked by the blocking body.

  Thereby, the driver of the vehicle can take the vehicle out of the parking space with a margin after starting the lowering of the blocking body.

  The present invention can be applied to entrances and exits of parking spaces for parking various vehicles such as automobiles, motorcycles, and bicycles (including motorbikes).

  In the present invention, the parking space refers to, for example, a garage (garage) installed in a house or on a site, a public pay parking lot (a contract parking lot such as a monthly parking lot or a coin parking lot), and the like.

  Therefore, according to the present invention, it is possible to prevent another person's vehicle from being parked in the self-parking space where the vehicle has left.

  In addition, when the parking space is a public pay parking lot, the entrance / exit is not only the entrance / exit of each contractor's parking space provided in this public pay parking lot, but also this public pay parking lot. An entrance (gate) is included.

  In addition, when the parking space is provided inside the house and a passage is provided at the side of the parking space, the blocking body blocks only the entrance / exit of the parking space. It may be used, and the entrance and the passage of the parking space may be blocked.

  According to the present invention, it is possible to obtain an effect that the installation work of the entrance / exit blocking device for the parking space can be performed more easily.

  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated based on drawing. The entrance / exit blocking device according to the present embodiment (in other words, the first embodiment) is provided in the first floor portion of the small house 1 shown in FIG. 1 and is a parking space for parking the automobile 2 as a vehicle. This is for shutting off the entrance / exit 4 of the garage (in other words, the garage) 3.

  FIG. 2 shows a front view of the garage 3 in a state where the automobile 2 shown in FIG. On the back side of the side of the garage 3 facing the road (the right side in FIG. 2), an entrance 6 for entering and exiting the house 1 is provided. From 4 to the entrance 6 is a passage 7 having stairs.

  FIG. 3 is a view showing when the automobile 2 shown in FIG. 2 has left the garage 3 and the entrance 4 of the garage 3 is blocked by the blocking body 11 of the entrance blocking apparatus according to the present embodiment. It is the same figure.

  As shown in FIG. 3, the blocking body 11 according to the present embodiment for blocking the entrance / exit 4 of the garage 3 is fed out by a take-up shaft 10, which will be described later, with a specific structure in which upper ends are connected. The left and right two string-like members 12 to be wound and the horizontally long member 13 to which the lower ends of the respective string-like members 12 are coupled are configured. The two left and right string-like members 12 are arranged in the upper surface portion 13A of the horizontally long member 13 in the vicinity of both ends in the longitudinal direction of the horizontally long member 13, and therefore, the two string-like members 12 are The doorway 4 is spaced apart in the width direction.

  As shown in FIG. 2, the take-up shaft 10 that serves as an elevating means for raising and lowering the blocking body 11 is located above the opening 4 in the first floor portion of the house 1 that forms the doorway 4 of the garage 3. It arrange | positions inside the case member 9 attached to the edge 4A.

  The horizontally long member 13, which is a hollow rod-like member, has substantially the same length dimension as the width dimension that is the dimension in the width direction (left-right direction) of the garage 3. That is, the laterally long member 13 is a hollow rod-like member having a dimension that is long in the lateral direction that is the left-right direction.

  4 is a longitudinal sectional view of the entrance / exit blocking device according to the present embodiment in the state of FIG. 2, and FIG. 5 is a longitudinal sectional view of the entrance / exit blocking device according to the present embodiment in the state of FIG. 3.

  As shown in FIGS. 4 and 5, the upper ends 12 </ b> A of the left and right two string-like members 12 are connected to the winding shaft 10, and the lower ends 12 </ b> B are connected to the upper surface portion 13 </ b> A of the horizontally long member 13. It is connected. For this reason, each of these two string-like members 12 extends in the vertical direction from the take-up shaft 10 to the horizontally long member 13.

  As can be seen from FIGS. 4 and 5, the two string-like members 12 that are fed out and wound up from the winding shaft 10 are formed on the bottom surface portion 9 </ b> A of the case member 9 in which the winding shaft 10 is accommodated. It passes through the slit 9B.

  Further, a string-like member 15 to which an upper end portion 15A is coupled hangs down at the center in the longitudinal direction of the horizontally-long member 13 in the bottom surface portion 13B of the horizontally-long member 13 or substantially at the center. The lower end portion 15B is connected to the upper surface portion 14A of the disk-shaped magnet 14. For this reason, the string-like member 15 is a connecting member for connecting the magnet 14 to the horizontally long member 13.

  As described above, FIG. 3 is a diagram showing the time when the doorway 4 of the garage 3 is blocked by the blocking body 11 of the doorway blocking device according to the present embodiment. The member 13 does not land on the ground 5 which is a parking surface. That is, the height position of the horizontally long member 13 is set to a height position that prevents entry of a vehicle or a person into the garage 3 (for example, from the height position of an adult's knee as in the present embodiment shown in FIG. 3). The range up to about the height position of).

  On the ground 5, there is disposed a magnetic body 16 to which the magnet 14 is attracted when the doorway 4 of the garage 3 is blocked by the blocking body 11. The upper surface portion 16A of the magnetic body 16 is flush with or substantially flush with the ground 5. That is, the magnetic body 16 is buried in the ground with the upper surface portion 16 </ b> A exposed to the ground 5. The arrangement position of the magnetic body 16 on the ground 5 corresponds to or substantially corresponds to the position of the magnet 14 when the doorway 4 of the garage 3 is blocked by the blocking body 11.

  The area (surface area) of the upper surface portion 16A of the magnetic body 16 is larger than the area (surface area) of the bottom surface portion 14B of the magnet 14. As described above, since the magnet 14 is connected to the horizontally long member 13 via the string-like member 15, when the entrance 4 of the garage 3 is blocked by the blocking body 11, the magnet 14 is attracted to the magnetic body 16. This is because it is considered that the magnet 14 may move laterally due to wind pressure or the like, and the magnet 14 may be detached from the magnetic body 16.

  In the present embodiment, as shown in FIGS. 2 and 4, when the automobile 2 is in the garage 3, the horizontally long member 13 has a case where the upper surface portion 13 </ b> A of the horizontally long member 13 is the winding shaft 10. In contact with the bottom surface 9 </ b> A of the member 9, the member 9 is arranged above the entrance / exit 4 of the garage 3.

  FIG. 6 is a diagram showing an internal structure of the winding shaft 10 shown in FIGS. 4 and 5. In addition, in this FIG. 6, the display of the string-like member 12 drawn out and wound up from the winding shaft 10 is omitted.

  As shown in FIG. 6, the winding shaft 10 made of a hollow member is rotatable around the first and second central shafts 17 and 18 at both ends. The first central shaft 17 is coupled to one of the left and right brackets 21 and 22 attached to the ceiling member 8 that forms the upper edge 4A of the opening 4 of the house 1 and does not rotate. The first central shaft 17 is inserted into a bearing member 19 coupled to one open end of the winding shaft 10.

  Inside the winding shaft 10, a rotating member 51 coupled to the winding shaft 10 and rotating integrally with the winding shaft 10 is incorporated, and the second central shaft 18 is coupled to the rotating member 51. Therefore, the second central shaft 18 is rotatably inserted into the bearing member 20 coupled to the other bracket 22.

  In addition, a rotating member 23 coupled to the winding shaft 10 and rotating integrally with the winding shaft 10 is incorporated in the winding shaft 10, and is returned to the rotating member 23 and the first central shaft 17. Both ends of the spring 24 are connected.

  This return spring 24 housed inside the take-up shaft 10 accumulates the return spring force when the take-up shaft 10 rotates forward in order to feed the string-like member 12 downward.

  As described above, the return spring 24 in which the spring force is accumulated by the rotating winding shaft 10 when the string-like member 12 is drawn out from the winding shaft 10 is disposed inside the winding shaft 10. .

  In this embodiment, the spring force of the return spring 24 is always the weight of the blocking body 11 (the weight of the string-like member 12 fed out from the take-up shaft 10, the weight of the horizontally long member 13, and the string-like member 15). And the sum of the weights of the magnets 14) or larger than this.

  For this reason, a rotational force (reverse rotational force) in the direction of winding the string-like member 12 always acts on the winding shaft 10. That is, the winding shaft 10 is always subjected to a force for reverse rotation to wind the string-like member 12.

  Next, the operation of the doorway shut-off device according to this embodiment will be described.

  First, the operation of blocking the entrance / exit 4 of the garage 3 with the blocking body 11 will be described.

  In this embodiment, after the automobile 2 is completely removed from the garage 3, a driver of the automobile 2, a passenger, a resident of the house 1 who does not go out of the automobile 2, etc. shuts the entrance / exit 4 of the garage 3 with the blocking body 11. Work to do.

  This blocking operation is performed by the operator placing a hand on the disk-shaped magnet 14 or the string-like member 15 and pulling the magnet 14 or the string-like member 15 downward. Accordingly, the horizontally long member 13 whose upper surface portion 13A is in contact with the bottom surface portion 9A of the case member 9 is lowered. This pulling operation is performed until the magnet 14 comes into contact with and attracts the magnetic body 16, that is, until the magnet 14 contacts the ground 5. When the operator releases his / her hand from the magnet 14 or the string-like member 15 during the pulling operation, the winding shaft 10 is reversed by the spring force accumulated in the return spring 24 disposed inside the winding shaft 10. Rotate. Thereby, since the string-like member 12 is wound up by the winding shaft 10, the blocking body 11 rises and returns to the state shown in FIG. 2 and FIG.

  The force with which the magnet 14 is attracted to the magnetic body 16 is larger than the reverse rotational force of the winding shaft 10. For this reason, when the magnet 14 is attracted to the magnetic body 16 by the pulling operation described above, the state of the blocking body 11 shown in FIG. 3 is maintained (maintained). That is, the state where the doorway 4 is blocked by the blocking body 11 is maintained.

  For this reason, the magnet 14 and the magnetic body 16 constitute a blocking state holding means for holding the blocking state of the entrance / exit 4 by the blocking body 11. The magnet 14 is a locking member connected to the horizontally long member 13 by a string-like member 15, and the magnetic body 16 is provided on the ground 5 that is a parking surface, and is locked by the magnet 14. It is a member.

  In the present embodiment, the magnet 14 and the string-like member 15 are operation members for lowering the blocking body 11.

  In the present embodiment, the magnet 14 and the magnetic body 16 may be reversed. That is, a disk-like magnetic body may be connected to the horizontally long member 13 via the string-like member 15, and a magnet may be disposed on the ground 5.

  In the present embodiment, the magnet 14 may be a hook member, and the magnetic body 16 may be a pin member or a ring member that can be hooked to the hook member.

  Next, an operation for releasing the state where the doorway 4 of the garage 3 is blocked by the blocking body 11 will be described.

  This operation is performed when the automobile 2 that has been delivered from the garage 3 is re-entered into the garage 3, and the operator (as described above, the driver of the automobile 2, the passenger, or the automobile 2 does not go out). A resident of the house 1, for example, puts his hand on the magnet 14 or the string-like member 15 and pulls the magnet 14 or the string-like member 15 upward to separate the magnet 14 adsorbed on the magnetic body 16 from the magnetic body 16. That's fine. Thereafter, the operator may release the hand from the magnet 14 or the string-like member 15.

  As described above, the rotational force (reverse rotational force) in the direction of winding the string-like member 12 is constantly acting on the winding shaft 10. For this reason, after separating the magnet 14 from the magnetic body 16, the string-like member 12 is taken up by the take-up shaft 10, and thereby the horizontally long member 13 rises to the state shown in FIGS. 2 and 4. .

  Thus, in the present embodiment, the winding shaft 10 and the return spring 24 disposed inside the winding shaft 10 constitute lifting means for lifting and lowering the blocking body 11.

  In the present embodiment, as shown in FIGS. 3 and 5, the blocking body 11 is lowered while the automobile 2 is in the garage 3 as shown in FIGS. 2 and 4. Thus, the entrance / exit 4 may be blocked by the blocking body 11.

  In this embodiment described above, the entrance / exit blocking device for blocking the entrance / exit 4 of the garage 3 that is a parking space is disposed above the ground 5 that is the parking surface of the garage 3.

  For this reason, according to this embodiment, compared with the conventional entrance-exit blocker embed | buried under the ground, installation work can be performed more easily.

  In this embodiment, when the automobile 2 is in the garage 3, the entrance / exit 4 can be blocked by the blocking body 11. However, it is limited to the case where the length dimension (the dimension in the front-rear direction) of the automobile 2 is smaller than the length dimension of the garage 3. That is, it is limited to the case where the automobile 2 in the garage 3 is not protruding from the entrance 4.

  In the present embodiment, the operation of lowering the blocking body 11 is performed when the horizontally long member 13 is provided with a locked portion and has a locking portion that is locked to the locked portion and is lifted. A rod-shaped member having a length that reaches the locked portion is prepared, and the rod-shaped member having the locking portion locked to the locked portion of the laterally long member 13 is pulled down (pulled down).

  According to this embodiment, the effect that the inside of the garage 3 can be made harder to see from the outside is also obtained as compared with the first and second embodiments described above.

  In the present embodiment, the member to be wound may be constituted by a plurality of sheet-like members arranged in parallel in the width direction of the garage 3.

  FIG. 9 is a view similar to FIG. 3 showing the parking space doorway shut-off device according to the fourth embodiment.

  The blocking body 29 according to the present embodiment is configured to block the entrance / exit of the garage 3 and the entrance / exit of the passage 7 to the entrance 6 provided on the side of the garage 3.

  For this reason, the blocking body 29 has a width dimension straddling the doorway 4 of the garage 3 and the doorway of the passage 7.

  That is, as shown in FIG. 9, the horizontally long member 31 that constitutes the blocking body 29 has a length dimension (dimension in the left-right direction) straddling the entrance / exit 4 of the garage 3 and the entrance / exit of the passage 7.

  For this reason, the length dimension (dimension in the left-right direction) of a winding shaft (not shown) for feeding and winding the three string-like members 30 whose lower ends are connected to the upper surface portion 13A of the horizontally long member 31 is also the garage. 3 and a case member 28 for accommodating the take-up shaft is also provided with the entrance 4 of the garage 3 as shown in FIG. It has a length dimension straddling the entrance / exit of the passage 7. The length dimension of the slit 28 </ b> B provided in the bottom surface portion 28 </ b> A of the case member 28 also has a length dimension straddling the entrance / exit 4 of the garage 3 and the entrance / exit of the passage 7.

  The three string-like members 30 are connected to the upper surface portion 31A of the laterally long member 31 so as to be separated from each other in the width direction of the garage 3. The upper end portion of the string-like member 15 for connecting the magnet 14 to the horizontally long member 31 is connected to the portion.

  According to this embodiment, not only can the entrance of the vehicle and the person into the garage 3 be blocked by the blocking body 29 having a width across the entrance 4 of the garage 3 and the entrance of the passage 7, but also the entrance 6 It is possible to block the entry of people and vehicles (motorcycles, bicycles, etc., not cars).

  FIG. 10 is a view similar to FIG. 3 showing the doorway shut-off device according to the fifth embodiment (in other words, a modification of the above-described first embodiment). FIG. 11 is a view similar to FIG. 6 showing the internal structure of the winding shaft 10 of the doorway shut-off device shown in FIG.

  As shown in FIG. 11, a return spring 24 is disposed inside the winding shaft 10 as in the first to fourth embodiments described above.

  However, in this embodiment, the spring force of the return spring 24 is always smaller than the dead weight of the blocking body 11. That is, in the present embodiment, the spring force of the return spring 24 is always the weight of the blocking body 11 (the weight of the string-like member 12 fed out from the winding shaft 10, the weight of the laterally long member 13, and the specific structure. (The sum of the weight of the locked member 33, the weight of the string-like member 15, and the weight of the magnet 14).

  For this reason, a rotational force (positive rotational force) in the direction in which the string-like member 12 is fed out always acts on the winding shaft 10. That is, the winding shaft 10 is always subjected to a force to rotate forward in order to feed out the string-like member 12.

  As shown in FIG. 10, the above-described locked member 33 is attached to the central portion in the length direction of the horizontally long member 13 on the upper surface portion 13 </ b> A of the horizontally long member 13. A to-be-latched hole 33A is formed. Further, as shown in FIGS. 10 and 11, the upper surface of the bottom surface portion 9 </ b> A of the case member 9 (excluding the slit 9 </ b> B portion), and a position just above the locked member 33, A locking device 34 whose structure will be described later is arranged.

  FIG. 12 is a view similar to FIG. 5 showing a state in which the blocking body 11, which has been lowered as the string-like member 12 is drawn out from the winding shaft 10, blocks the entrance / exit 4. 13 shows that the upper surface portion 13A of the horizontally long member 13 of the blocking body 11 in which the string-like member 12 has been wound up by the winding shaft 10 from the state of FIG. 12 is the lower surface of the bottom surface portion 9A of the case member 9. It is a figure similar to FIG. 4 which shows the state which is contact | abutting, ie, the state by which the non-blocking state of the entrance / exit 4 is hold | maintained.

  As shown in FIG. 13, the locking device 34 is configured such that the upper surface portion 13 </ b> A of the horizontally long member 13 becomes the bottom surface portion 9 </ b> A of the case member 9 when the string-like member 12 of the blocking body 11 is wound around the winding shaft 10. A locking member 60 is provided to prevent the blocking body 11 from descending by being inserted and locked into the locked hole 33A of the locked member 33 when it is in contact with the lower surface of the locked member 33.

  The normal locking member 60 that is swingable up and down is inserted into the locked hole 33A by operating a stop mechanism 70 described later with a specific structure provided inside the locking device 34. The horizontal posture is stopped, and thereby the non-blocking state of the doorway 4 is maintained (maintained).

  As described above, the winding shaft 10 is always subjected to a force to rotate forward in order to feed the string-like member 12, so that the string-like member 12 of the blocking body 11 is wound around the take-up shaft 10. When it is in the state, it is necessary to prevent the winding shaft 10 from rotating forward.

  For this reason, in this embodiment, the string-like member 12 of the blocking body 11 is wound around the take-up shaft 10, and the upper surface portion 13A of the horizontally long member 13 is in contact with the lower surface of the bottom surface portion 9A of the case member 9. The non-blocking state holding means for holding the non-blocking state is provided. The non-blocking state holding unit includes the above-described locked member 33 and the locking device 34 having the locking member 60. It is configured to include.

  As shown in FIG. 10, the blocking body 11 in the state shown in FIG. 13 is lowered inside the side wall 46 of the opening 4 of the narrow house 1 that forms the doorway 4 of the garage 3. Therefore, an operation member 42, which will be described later with a specific structure for releasing the operation of the stop mechanism 70 described above, is disposed. One end of a wire 35 that is a string-like member is connected to the operation member 42, and the direction of the wire 35 is changed by two upper and lower rollers 37 and 38 disposed inside the side wall 46. It extends to the stop device 34.

  When the operation of the stop mechanism 70 is released by the pulling operation of the wire 35 by the turning operation of the operation member 42, the locking member 60 assumes a downward swinging posture by the spring force, as will be described later, and the blocking body 11. Is switched to a state where it can be lowered.

  As a result, the blocking body 11 has its own weight (the weight of the string-like member 12 fed out from the winding shaft 10, the weight of the horizontally long member 13, the weight of the locked member 33, and the string-like shape. The descent by the sum of the weight of the member 15 and the weight of the magnet 14 is started.

  That is, when the operation member 42 is operated, the non-blocking state holding of the entrance / exit 4 by the non-blocking state holding means is released, and when the string-like member 12 is drawn out from the winding shaft 10, the horizontally long member 13 is 10 is lowered to a predetermined height position shown in FIG. 10, and the entrance / exit 4 is blocked by the blocking body 11.

  As described above, in this embodiment, the spring force of the return spring 24 arranged inside the winding shaft 10 is always smaller than the dead weight of the blocking body 11. Moreover, in this embodiment, the means for stopping the forward rotation of the winding shaft 10 after the non-blocking state holding of the entrance / exit 4 by the non-blocking state holding unit is released is not provided.

  For this reason, in this embodiment, after the operation member 42 is operated to release the non-blocking state holding of the entrance / exit 4 by the non-blocking state holding means, the forward rotation of the winding shaft 10 causes the upper end 12A to move. This is continued until the entire string-like member 12 is drawn out.

  As a result, in the state shown in FIG. 12, that is, in the state where the entrance / exit 4 is blocked by the blocking body 11, the string-like member 12 excluding the upper end portion 12 </ b> A hangs down from the lowermost portion of the winding shaft 10. It becomes.

  As can be seen from FIGS. 10 and 12, in this embodiment, the feed amount of the string-like member 12 from the take-up shaft 10, in other words, the length of the string-like member 12 that is fed from the take-up shaft 10 is the entrance / exit 4. The amount of feeding so that the height position of the horizontally long member 13 of the blocking body 11 is the same as or substantially the same as the height position of the horizontally long member 13 in each of the first to fourth embodiments described above. It has become.

  In the state shown in FIGS. 10 and 12, the string-like member 12 is subjected to a downward load that is a total of at least the weight of the horizontally long member 13 and the weight of the locked member 33. A downward tension is generated in the string-like member 12, and as described above, the string-like member 12 hangs down from the lowermost part of the winding shaft 10 (in other words, a state in which the string-like member 12 extends straight in the vertical direction). Become.

  In the state shown in FIGS. 10 and 12, the magnet 14 is placed on the upper surface of the magnetic body 16 disposed on the ground 5 and is attracted to the magnetic body 16. A load corresponding to the weight of the magnet 14 is not applied to the string-like member 12.

  As shown in FIG. 11, in this embodiment, when the winding shaft 10 rotates forward to feed out the string-like member 12, a speed reducing device 32 for reducing the rotational speed of the winding shaft 10 is provided. The second central shaft 18, which is a rotating shaft of the winding shaft 10, is attached.

  In the present embodiment, the speed reduction device 32 is a rotary damper, and a plurality of blades connected to the second central shaft 18 are attached to the inside of the speed reduction device 32 via a one-way clutch (not shown). Yes.

  When the take-up shaft 10 rotates in the forward direction, each blade rotates in the viscous fluid filled in the reduction gear 32 due to the connecting action of the one-way clutch. For this reason, the winding shaft 10 rotates forward at a low speed due to the resistance force of the viscous fluid.

  On the other hand, when the take-up shaft 10 rotates reversely to raise the blocker 11, the rotation of the second central shaft 18 of the take-up shaft 10 is not transmitted to the respective blades due to the cutting action of the one-way clutch. For this reason, the winding shaft 10 rotates in reverse at a high speed.

  In the present embodiment, the speed reducer 32 is a speed reducing means for reducing the descending speed (falling speed) of the blocking body 11. In other words, in the present embodiment, the take-up shaft 10 constituting the elevating means is provided with a speed reducing device 32 that is a speed reducing means for reducing the descending speed of the blocking body 11.

  For this reason, in this embodiment, the driver of the automobile 2 himself operates the operating member 42 to start the lowering of the blocking body 11, and then the driver gets on the automobile 2 and removes the automobile 2 from the garage 3. Even if it leaves, the blocker 11 blocks the entrance / exit 4 after the automobile 2 has completely exited from the entrance / exit 4.

  That is, in this embodiment, after the driver of the automobile 2 himself operates the operation member 42 to start the lowering of the blocking body 11, the driver gets on the automobile 2 and removes the automobile 2 from the garage 3. Even if it makes it, it will not be in the state which the blocker 11 blocked the entrance / exit 4 until the motor vehicle 2 completely exited from the entrance / exit 4.

  As described above, in this embodiment, the blocking body 11 is lowered at a very slow speed (low speed) by the speed reducer 32. After starting to descend, the car 2 can be taken out from the garage 3 with a margin.

  As described above, similarly to the first to fifth embodiments, also in this embodiment, the return spring 24 is disposed inside the winding shaft 10.

  When the shield 11 is lowered by its own weight, the string-like member 12 of the shield 11 is drawn out from the take-up shaft 10. At this time, the spring force is accumulated on the return spring 24 by the rotating take-up shaft 10. The For this reason, the descent due to the dead weight of the blocking body 11 is decelerated by the amount by which the return spring 24 is accumulated. In other words, this rotational speed when the winding shaft 10 rotates forward to feed out the string-like member 12 of the blocking body 11 is also reduced by the accumulation of spring force in the return spring 24.

  Thus, in the present embodiment, the lowering speed (in other words, the normal rotational speed of the winding shaft 10) due to the dead weight of the blocking body 11 is not only decelerated by the speed reducing device 32 described above, but also the return spring 24 is spring-loaded. It is also decelerated by the accumulation of force.

  In order to release the shut-off state of the entrance / exit 4 by the shut-off body 11, the shut-off body 11 in a state of shutting off the entrance / exit 4 is lifted. A large push-up force is applied to the horizontally long member 13 to raise the blocker 11 vigorously.

  As a result, due to the pushing-up force applied to the horizontally long member 13 and the spring force accumulated in the return spring 24, the blocking member 11 causes the string-like member 12 to be wound around the winding shaft 10 as shown in FIG. Thus, the horizontally long member 13 is brought into a non-blocking state in which the horizontally long member 13 is in contact with the lower surface of the bottom surface portion 9A of the case member 9.

  When the horizontally long member 13 of the blocking body 11 is lifted and raised, the spring force accumulated in the return spring 24 is used to rotate (reversely rotate) the winding shaft 10 for winding the string-like member 12 of the blocking body 11. Since the spring force is used as an auxiliary force, the horizontally long member 13 can be lifted lightly.

  As will be described later, the locking member 60 of the locking device 34 has upper and lower bifurcated portions, and the upper piece of the bifurcated portion of the locking member 60 that has been in a downward swinging posture. Is pushed up on the upper surface of the locked member 33 arranged on the upper surface portion 13A of the horizontally long member 13 of the blocking body 11, and the lower portion of the bifurcated portion of the locking member 60 thus returned to the horizontal posture. One part is inserted and locked in the locked hole 33 </ b> A of the locked member 33. Since the stop mechanism 70 at this time is returned to the original state at the same time when the locking member 60 returns to the horizontal posture, the state of the blocking body 11 is that the string-like member 12 is the winding shaft as described above. 10, the non-blocking state in which the horizontally long member 13 is in contact with the lower surface of the bottom surface portion 9A of the case member 9 is maintained.

  Next, a specific structure of the locking device 34 constituting non-blocking state holding means for holding the blocking body 11 in a non-blocking state will be described.

  As described above, in FIG. 12, the release of the operation of the stop mechanism 70 provided in the locking device 34 causes the locking member 60 to swing downward by a spring force, as will be described later. It is the longitudinal cross-sectional view of the entrance-and-exit blocker which concerns on this embodiment similar to FIG. 5 which shows the state which the interruption | blocking body 11 lowered | hung by the dead weight has interrupted the entrance / exit 4. FIG. Further, FIG. 13 shows that the upper piece 61A of the bifurcated portion 61 of the locking member 60 that has been in the downward swinging posture in FIG. The lower piece 61B of the locking member 60 pushed up on the upper surface of the disposed locked member 33 and thus returned to the horizontal posture is inserted and locked into the locked hole 33A of the locked member 33. It shows the state when

  FIG. 14 is an enlarged view of the locking device 34 in FIG. 12, from an opening 34 </ b> B formed on the side surface of the metal case 34 </ b> A of the locking device 34 facing the string-like member 12 of the blocking body 11. This shows a state when the locking member 60 having the upper piece portion 61A and the lower piece portion 61B exposed to the blocking body 11 side is in a downward swinging posture. 15 is an enlarged view of the locking device 34 in FIG. 13, and the locking member 60 exposed from the opening formed in the case 34A of the locking device 34 maintains the horizontal posture. It shows the state when

  16 is a cross-sectional view taken along the line S16-S16 in FIG. 15, and shows a state where the locking member 60 is maintained in a horizontal posture by the operation of the stop mechanism 70. FIG. FIG. 17 is a cross-sectional view taken along line S17-S17 in FIG. 15, and shows a state when the locking member 60 is maintained in the horizontal posture by the operation of the stop mechanism 70, as in FIG.

In both cases, the locking member 60 maintains the horizontal posture by the operation of the stop mechanism 70. It is a figure which shows the state at the time of doing.

  As shown in FIG. 16, the locking device 34 is configured such that when the string-like member 12 of the blocking body 11 is in a non-blocking state in which the string-like member 12 is wound around the winding shaft 10, By inserting and locking in the locking hole 33A, the locking member 60 for maintaining the non-blocking state, the stop mechanism 70 for maintaining the locking member 60 in a horizontal posture, and the operation of the stop mechanism 70 are released. A stop mechanism release mechanism 100 is provided.

  As shown in FIG. 16, the locking member 60 is arranged in the locking device 34 at a substantially central portion in the length direction (left-right direction) of the locking device 34 that is the width direction (left-right direction) of the garage 3. As shown in FIG. 16, two brackets 76 and 77 are juxtaposed on both sides of the locking member 60 so as to sandwich the locking member 60. A swinging center shaft 64 (see FIGS. 16 and 19) is installed between the two brackets 76 and 77 so that the locking member 60 can swing up and down.

  As shown in FIG. 19, the locking member 60 is formed with a bifurcated portion 61 composed of an upper piece portion 61 </ b> A and a lower piece portion 61 </ b> B, and the direction opposite to the protruding direction of the bifurcated portion 61 in the locking member 60. This part is a rear extension 62 that extends away from the blocking body 11.

  The rearwardly extending portion 62 has a downward obliquely extending side 62 </ b> A that extends obliquely downward so as to move away from the blocking body 11 and away from the blocking body 11 in a state where the locking member 60 maintains a horizontal posture. The horizontal side 62B that extends horizontally and the rear end side 62C that extends obliquely downward so as to approach the blocking body 11 are formed. Therefore, the rearwardly extending portion 62 is defined as the projecting direction of the bifurcated portion 61. The shape extends so as to taper in the opposite direction.

  In addition, a columnar pin 63 that protrudes in the thickness direction of the locking member 60 made of a plate material is provided in the rearward extension 62 of the locking member 60. On the other hand, the bracket 76 disposed on the same side as the pin 63 is formed with a pin guide hole 76A having a shape curved in an oblique vertical direction.

  The locking member 60 is swingable about the swing center shaft 64 provided between the two brackets 76 and 77, and the lock member 60 is centered on the swing center shaft 64. And the pin 63 moves in the pin guide hole 76A.

  As shown in FIG. 19, the stop mechanism 70 is disposed on both sides of a roller 72 that is rotatable around a rotation shaft 72A for locking the locking member 60, and the rotation of the roller 72. It comprises an arm member 71 and a roller support member 73 for rotatably supporting the shaft 72A, and a spring 74 for pulling the arm member 71 to the blocking body 11 side.

  As shown in FIG. 19, the arm member 71 has a shape obtained by rotating a substantially square shape approximately 90 degrees clockwise in a state where the locking member 60 maintains a horizontal posture. From an upper obliquely extending portion 71A extending obliquely upward so as to be away from the lower portion, and a downward extending portion 71B having an inclined surface 71C extending obliquely downwardly so as to be away from the blocking body 11 and extending straight in the vertical direction It has become.

  A circular non-through hole 71E is formed on the surface of the arm member 71 on the bracket 76 side, and the tip end portion of the rotating shaft 72A of the roller 72 is inserted and fixed in the non-through hole 71E. A circular non-through hole 73A is formed on the surface of the roller support member 73 on the bracket 77 side, and the distal end portion of the rotating shaft 72A of the roller 72 is inserted into and fixed to the non-through hole 73A. That is, the arm member 71 supports the rotating shaft 72A of the roller 72 from the surface on the bracket 76 side, while the roller support member 73 supports the rotating shaft 72A of the roller 72 from the surface on the bracket 77 side. . Therefore, the roller 72 is rotatable about the rotation shaft 72A while being sandwiched between the arm member 71 and the roller support member 73.

  A through hole 71 </ b> F is formed in the upper part of the arm member 71, and similarly, a through hole 73 </ b> B is formed in the upper part of the roller support member 73. A cylindrical swinging central shaft 71G that is installed between the bracket 76 and the bracket 77 is inserted into the two through holes 71F and 73B. Therefore, the arm member 71 and the roller support member 73 are swingable about the swing center shaft 71G while sandwiching the roller 72.

  Further, as shown in FIG. 19, both ends of the inclined surface 71 </ b> C of the downwardly extending portion 71 </ b> B of the arm member 71 are bowl-shaped, and are disposed on the opposite side of the arm member 71 with a bracket 77 therebetween. A spring locking portion 71 </ b> D for locking one end of the spring 74 is provided so as to extend to a horizontally long and substantially rectangular opening 77 </ b> A formed on the lower left side of the bracket 77. The spring locking portion 71D is formed with a circular through hole 71H (see FIGS. 17 and 18) penetrating in the swinging direction of the arm member 71 for locking one end of the spring 74. .

  On the other hand, a spring locking member 75 made of a fastening tool such as a screw for locking the other end of the spring 74 is fixed to the surface of the bracket 77 opposite to the arm member 71 side. Therefore, a spring force in the direction of the spring locking member 75 acts on the arm member 71 that is swingable about the swing center shaft 71G.

  As shown in FIG. 20, an unlocking spring 86 for releasing the state where the locking member 60 maintains the horizontal posture is provided on the surface of the bracket 76 opposite to the locking member 60. . The locking release spring 86 is a torsion spring, and the spring center portion 86A is fixed to the bracket 76 by a coupling member 87 made of a fixing tool such as a screw.

  In a state where the locking member 60 maintains the horizontal posture, the lower end portion 86C of the both ends of the locking release spring 86 is screwed by the pin 63 of the locking member 60 that moves in the pin guide hole 76A. It is latched by a spring latching member 88 made of a fastening tool such as. On the other hand, since the upper end portion 86B is pushed down from above by the pin 63 of the locking member 60, the locking force release spring 86 accumulates a spring force obliquely upward.

  As shown in FIG. 16, the locking release lever 82 for releasing the state in which the locking member 60 maintains the horizontal posture includes a quarter-circle portion 82A having a substantially quarter-circular shape, and a substantially semi-circular shape.

In the right end portion of the connecting member 83, a substantially square opening 83A having a larger area than the projection 82E of the quarter circle portion 82A of the locking release lever 82 is formed.

  As shown in FIG. 16, since the protrusion 82E of the quarter-circle portion 82A of the locking release lever 82 is inserted through the opening 83A of the coupling member 83, the coupling member and the quarter-circle portion 82A of the locking release lever 82 are connected. 83 is connected to the opening 83A.

  As shown in FIG. 20, a lever member 91 and a lever member 91 are urged downwardly above a lock release spring 86 for releasing the state in which the lock member 60 maintains the horizontal posture. A spring 92 is arranged for this purpose.

  As shown in FIGS. 17 and 20, the lever member 91 has a substantially U-shaped shape that opens upward, and can swing around a swing center shaft 91 </ b> A installed on the bracket 94. It has become. The center portion 92A of the spring 92 is locked to the swinging center shaft 91A, the upper end portion 92B is locked to the upper portion 94A of the bracket 94, and the lower end portion 92C is the upper surface of the bottom portion 91B of the lever member 91. It is locked to.

  As shown in FIG. 20, in a state in which the locking member 60 maintains the horizontal posture, the lever member 91 is in a downward swinging posture due to the spring force of the spring 92. Therefore, the lever member 91 The tip of the bottom surface of the bottom 91B of the 91 is in contact with the pin 63 of the locking member 60, and the pin 63 is pressed down.

  As shown in FIG. 17, in the stop mechanism release mechanism 100 for releasing the stop mechanism 70, the operation member 42 is installed on the left side wall 46 (see FIG. 10) that forms the opening 4 as in this embodiment. If the first operating lever 101 for operating the stop mechanism releasing mechanism 100 and the operating member 42 are installed on the right side wall 49 (see FIG. 10) forming the opening 4, the stop mechanism is released. A second operating lever 102 for operating the mechanism 100, and a first arm member 103 and a second arm member for transmitting the mechanical movement of any one of these two operating levers to the locking release lever 82 104.

  As shown in FIG. 17, the right end portion of the first operating lever 101 is coupled to the lower portion 103A of the first arm member 103 with a fastening device such as a screw, and is in the direction of arrow A shown in FIG. S direction) and the arrow B direction. Further, a substantially circular through hole 101A is formed at the left end portion of the first operation lever 101, and a wire 35 which is a string-like member having one end coupled to the operation member 42 is formed in the through hole 101A. The other end is locked.

  Further, the left end portion of the second operation lever 102 is coupled to the upper portion 103B of the first arm member 103 with a fastening tool such as a screw, and is slidable in the directions of arrows C and D shown in FIG. Yes. Although a substantially circular through hole 102A is formed at the right end of the second operation lever 102, in this embodiment, the operation member 42 is installed on the left side wall 46 on the garage 3 side. The wire is not locked in the through hole 102A.

  As shown in FIG. 16, one end of the connecting shaft 106 is fixed to a substantially central portion of the first arm member 103 by welding or the like, and the other end of the connecting shaft 106 is fixed to the upper portion of the second arm member 104 by welding or the like. For this reason, the first arm member 103 and the second arm member 104 are coupled to each other via a columnar connecting shaft 106.

  A bracket 105 having a substantially U-shaped cross section is provided between the first arm member 103 and the second arm member 104. The bracket 105 includes a rectangular horizontal extending portion 105A coupled to the case 34A with a fastening member such as a screw, and two rising portions 105B rising vertically upward from both ends of the horizontal extending portion 105A. 105C.

  A circular through hole 105D shown in FIG. 17 is formed in the upper portion of the rising portion 105B arranged on the first arm member 103 side. Similarly to this, the circular through hole 105D is arranged on the second arm member 104 side. A circular through-hole 105E shown in FIG. 17 is formed in the upper portion of the rising portion 105C, and these two through-holes 105D and 105E are formed at the same height.

  A connecting shaft 106 that connects the first arm member 103 and the second arm member 104 is rotatably inserted into the two through holes 105D and 105E, and is horizontally installed on the bracket 105. It is in a state.

  For this reason, the first arm member 103 and the second arm member 104 connected to the connecting shaft 106 are swingable about the connecting shaft 106 in the directions of arrows E and F shown in FIG. When the first arm member 103 swings about the connecting shaft 106, the second arm member 104 swings in the same direction as the swing direction of the first arm member 103 in conjunction with this. .

  As shown in FIGS. 17 and 18, when one end is coupled to the operation member 42, and the wire 35 serving as a coupling means for coupling the operation member 42 and the locking device 34 is pulled, the wire 35 When the first operation lever 101 whose other end is locked to the through hole 101A is pulled in the direction of arrow S, the first arm member 103 is moved in the direction of arrow U shown in FIG. While swinging, the second arm member 104 also swings in the direction of arrow U about the connecting shaft 106.

  Next, an operation until the locking member 60 that is maintained in the horizontal posture by the operation of the stop mechanism 70 becomes a downward swinging posture by the operation of the stop mechanism release mechanism 100 will be described.

  As shown in FIG. 19, in a state where the locking member 60 is maintained in the horizontal posture by the operation of the stop mechanism 70, the roller 72 sandwiched between the arm member 71 and the roller support member 73 is engaged with the locking member 60. The rear extension 62 is mounted so as to ride on the tip of the downward slant extension 62A.

  At this time, as shown in FIG. 20, the pin 63 of the locking member 60 pushes down the upper end portion 86 </ b> B of the locking release spring 86 from above. The spring force that pushes upward is accumulated.

  As shown in FIG. 17, the wire 35 having one end coupled to the operation member 42 and the other end locked to the through hole 101 </ b> A is pulled, thereby being connected to the upper portion 103 </ b> B of the first arm member 103. 1 The operation lever 101 slides in the direction of arrow S (the direction of arrow A in FIG. 16). As a result, the first arm member 103 swings in the direction of arrow U about the connecting shaft 106 as shown in FIG. At this time, the second operating lever 102 connected to the lower portion of the first arm member 103 slides in the direction of arrow T (the direction of arrow C in FIG. 16).

  On the other hand, the second arm member 104 connected to the first arm member 103 via the connecting shaft 106 installed on the bracket 105 also has an arrow U around the connecting shaft 106 in the same manner as the first arm member 103. It swings in the direction (arrow E direction in FIG. 16).

  At this time, the spring 107 whose one end is locked to the through hole 104A and the other end is locked to the locking member 108 extends in the direction of the arrow Q as shown in FIG. The spring force in the R direction is accumulated.

  As shown in FIG. 18, when the second arm member 104 continues to swing in the direction of the arrow U (the direction of the arrow E in FIG. 16), the corner portion of the upper end of the second arm member 104 becomes the locking release lever. It will contact | abut so that the quarter circle part 82A of 82 may be extruded. Accordingly, as shown in FIG. 16, the latch release lever 82 starts to swing around the swing center shaft 82D, and the quarter circle portion 82A of the lock release lever 82 swings in the direction of arrow G. The semicircular portion 82B swings in the direction of arrow J, and the protruding portion 82C swings in the direction of arrow K. That is, as shown in FIG. 19, the protrusion 82C of the locking release lever 82 that is in contact with the downwardly extending portion 71B of the arm member 71 slides (swings) in the direction of arrow a.

  FIG. 21 shows a state immediately after the operation of the stop mechanism 70 maintaining the locking member 60 in the horizontal posture is released from the state of FIG. 19 and the locking member 60 changes to the downward swinging posture. It is shown. Similarly, FIG. 22 shows a state immediately after the operation of the stop mechanism 70 maintaining the locking member 60 in the horizontal posture is released from the state of FIG. 20 and the locking member 60 changes to the downward swinging posture. This indicates the state.

  As described above, when the downwardly extending portion 71B of the arm member 71 is pushed out to the protruding portion 82C of the locking release lever 82, as shown in FIG. Swing in the direction (arrow M direction in FIG. 16) is started. At the same time, the roller 72 placed so as to ride on the tip of the downwardly inclined portion 62A of the locking member 60 rotates in the direction of the arrow d and separates from the downwardly inclined portion 62A of the locking member 60. To go.

  For this reason, as shown in FIG. 22, the upper end 86B of the unlocking spring 86 is repelled in the direction of the arrow i by the spring force accumulated in the unlocking spring 86, so that the upper end 86B is pushed down from above. The pin 63 of the locking member 60 is pushed up and moves in the direction of the arrow e in the pin guide hole 76A of the bracket 76. As a result, the locking member 60 starts swinging in the arrow g direction around the swing center shaft 64.

  When the locking member 60 swings in the direction of the arrow g, the lower piece 61B of the bifurcated portion 61 that has been inserted and locked into the locked hole 33A of the locked member 33 is detached from the locked hole 33A. To do. As a result, as shown in FIG. 21, the locked member 33 is lowered in the direction of the arrow h, and the blocking body 11 that has been in the non-blocking state starts to drop due to its own weight.

  In the present embodiment, the operation of the operation member 42 for pulling the wire 35 may be stopped after confirming that the blocking body 11 has started to descend due to its own weight. That is, the operation of the operation member 42 for pulling the wire 35 is performed until the blocking body 11 starts to descend due to its own weight.

  As described above, since the spring force of the spring 107 in the direction of the arrow R is accumulated in the second arm member 104, as shown in FIG. By stopping the pulling operation of the wire 35 locked in the hole 101A, the first arm member 103 swings by being pulled in the direction of arrow F by the spring force of the accumulated spring 107 and returns to the original position. Return. At the same time, the second arm member 104 swings in conjunction with the first arm member 103 and returns to the original position. Accordingly, the first operating lever 101 slides in the direction of arrow B and the second operating lever 102 slides in the direction of arrow D, so that each returns to its original position.

  Further, as shown in FIG. 19, the protruding portion 82 </ b> C of the unlocking lever 82 that has pushed the downward extending portion 71 </ b> B of the arm member 71 by sliding (swinging) in the direction of the arrow a also causes the wire 35 to be connected. When the operation of the operation member 42 for towing is stopped, the original position shown in FIGS. 19 and 21 is restored (this mechanism will be described later).

  As shown in FIG. 21, when the arm member 71 swings in the arrow b direction, the spring 74 locked in the through hole 71H (see FIG. 17) of the spring locking portion 71D is moved in the arrow c direction. Elongate. For this reason, in the state in which the horizontal posture of the locking member 60 is released, the spring 74 accumulates a spring force in a direction opposite to the arrow c direction. That is, while the locking member 60 is in the downward swinging posture, the spring 74 accumulates a spring force in a direction opposite to the arrow c direction.

  Next, the state in which the horizontal posture is maintained is released by the operation of the stop mechanism release mechanism 100, and the locking member 60 that has been in the downward swinging posture is moved again, and the stop mechanism 70 is operated again by the raised blocking body 11. The operation until the locking member 60 is again in a state of maintaining the horizontal posture will be described.

  FIG. 23 shows the horizontally long member 13 of the blocking body 11 in which the upper piece 61A of the bifurcated portion 61 of the locking member 60 that has been in the downward swinging posture from the state shown in FIG. The state just before being pushed up by the upper surface of the to-be-latched member 33 arrange | positioned at 13 A of upper surface parts is shown. Similarly, in FIG. 24, the upper piece 61 </ b> A of the bifurcated portion 61 of the locking member 60 that has been in the downward swinging posture from the state of FIG. The state immediately before being pushed up on the upper surface of the locked member 33 disposed on the upper surface portion 13A of the horizontally long member 13 is shown.

  When the upper portion of the locked member 33 comes into contact with the upper piece 61A of the bifurcated portion 61, the locking member 60 starts swinging in the arrow m direction around the swing center shaft 64. At this time, the pin 63 of the locking member 60 moves in the direction of the arrow o in the pin guide hole 76A.

  On the other hand, the roller 72 of the arm member 71 that has been in contact with the rear end side 62C of the rearward extending portion 62 of the locking member 60 rotates in the direction of the arrow q, and the spring 74 in which the spring force in the direction of the arrow r is accumulated. Since the spring locking portion 71D of the arm member 71 is pulled in the direction of the arrow r, the arm member 71 starts swinging in the direction of the arrow p (the direction of the arrow N in FIG. 16) about the swing center axis 71G. .

  As the locking member 60 swings in the arrow m direction, the lower piece 61B of the bifurcated portion 61 of the locking member 60 is inserted into the locked hole 33A of the locked member 33.

  On the other hand, as the swinging of the arm member 71 in the direction of the arrow p proceeds, the roller 72 of the arm member 71 rotates in the direction of the arrow q while rotating downward in the downwardly extending portion 62A of the locking member 60. It will be placed so that it rides on the tip.

  The locking member 60 that has been swinging in the direction of the arrow m is in a horizontal posture, and at the same time, the downwardly extending portion 71B of the arm member 71 that has been pulled by the spring 74 and swinging in the direction of the arrow p. However, since it abuts against the protrusion 82C of the locking release lever 82, the swing of the arm member 71 in the direction of the arrow p is stopped, and the rotation of the roller 72 of the arm member 71 in the direction of the arrow q is also stopped.

  At the same time that the locking member 60 is in the horizontal posture, the roller 72 of the arm member 71 is completely on the tip of the lower obliquely extending portion 62A of the rearward extending portion 62 of the locking member 60, that is, the locking The arm member 71 swings so as to be in a state of being completely locked to the downward inclined extending portion 62A of the rearward extending portion 62 of the member 60. For this reason, the subsequent locking members 60 maintain the horizontal posture as shown in FIG.

  As a result, the lifted blocking body 11 is such that the string-like member 12 of the blocking body 11 is wound around the winding shaft 10 and the upper surface portion 13A of the horizontally long member 13 comes into contact with the lower surface of the bottom surface portion 9A of the case member 9. The state, that is, the non-blocking state shown in FIG. 13 is maintained (maintained).

  As shown in FIG. 24, on the opposite side of the bracket 76 in FIG. 23, the pin 63 moving in the direction of the arrow o pushes down the upper end portion 86B of the locking release spring 86 in the direction of the arrow s. The release spring 86 accumulates a spring force in a direction opposite to the arrow s direction, that is, a spring force in a direction of pushing the pin 63 obliquely upward. Further, the lever member 91 has a lower end portion 92C of the spring 92 that is moved by the spring force in the arrow u direction accumulated in the spring 92 as the pin 63 of the locking member 60 moves in the arrow o direction. The upper surface of the bottom portion 91B is pushed down.

  25 is an enlarged cross-sectional view of the operation member 42 shown in FIG. 10, and FIG. 26 is a state when the operation member 42 is operated to release the stop mechanism 70 from the state of FIG. That is, the state when the wire 35 is being pulled is shown.

  The operation member 42 is housed in a recess 47 provided in the left side wall 46 that forms the left peripheral edge of the entrance 4, and the opening of the recess 47 is normally a shaft that is vertically installed in the recess 47. It is closed by a lid member (cover member) 39 that is rotatable (openable and closable) around the member 40.

  The operation member 42 is rotatable about a shaft member 43 installed horizontally in the recess 47, and as described above, one end of the operation member 42 is connected to the first operation lever 101 of the locking device 34. The other end of 35 is connected to the operation member 42.

  The recess 47 is provided with a guide roller 38 (see also FIG. 10) for guiding the other end of the wire 35 connected to the operation member 42 in the vertical direction (in other words, changing the direction). ing. The guide roller 38 around which the wire 35 is wound is rotatable around a shaft member 44 installed horizontally in the recess 47.

  10, the wire 35 whose direction is changed in the vertical direction by the guide roller 38 in the recess 47 is a vertical hole space 45 formed from the upper surface of the recess 47 in the side wall 46 (see FIG. 25). After passing through the guide roller 37 disposed near the uppermost portion of the vertical hole space 45 and rotatable about a shaft member (not shown), the direction is changed in the horizontal direction, and then the locking device 34 is turned. The first operating lever 101 is connected.

  In order to release the stop mechanism 70 of the locking device 34, first, the knob member 41, which is a handle member provided on the front surface of the lid member 39 that normally closes the recess 47, is picked, and the lid member 39 is moved forward. Open to.

  Thereafter, a hand is inserted into the upper part of the recess 47 and the upper part of the operation member 42 is pressed by the entire palm. Then, as shown in FIG. 26, by pulling the operation member 42 pressed by the entire palm to the front side, the operation member 42 rotates downward on the doorway 4 side (arrow w direction) with the shaft member 43 as the center. Start. As a result, the wire 35 guided by the guide roller 38 in the recess 47 is also pulled in the directions of the arrows x and y.

  As described above, one end of the wire 35 is locked in the through hole 101A of the first operating lever 101 of the stop mechanism releasing mechanism 100 of the locking device 34, and therefore the first operating lever 101 is shown in FIG. As described above, the first arm member 103 and the second arm member 104 are swung in the arrow U direction as shown in FIG. The corner portion of the upper end portion of the second arm member 104 that has swung in the direction of the arrow U abuts on the quarter circle portion 82 </ b> A of the locking release lever 82.

  Thereby, as shown in FIG. 16, the lock release lever 82 starts to swing around the swing center shaft 82D, and the protrusion 82C of the lock release lever 82 moves to the arrow as shown in FIG. It slides in the a direction and comes into contact with the downwardly extending portion 71B of the arm member 71. For this reason, the stop mechanism 70 is cancelled | released and, as a result, the interruption | blocking body 11 currently hold | maintained in the non-blocking state starts the fall by own weight.

  As described above, in this embodiment, the locking member 33, the locking member 60, and the locking device 34 having the stop mechanism 70 have the string-like member 12 of the blocking body 11 wound around the winding shaft 10. The non-blocking state holding means for holding in the non-blocking state that is set is configured.

  In the present embodiment, the operation member 42, the wire 35, the first and second operation levers 101 and 102, and the stop mechanism release mechanism 100 release the non-blocking state holding state by the non-blocking state holding unit. Therefore, the non-blocking state holding state canceling means is configured.

  In this embodiment, the non-blocking state holding state releasing unit releases the non-blocking state holding state by the non-blocking state holding unit, so that the blocking body 11 starts to descend due to its own weight.

  FIG. 27 is a view similar to FIG. 3 showing the doorway shut-off device according to the sixth embodiment (in other words, a modification of the above-described fifth embodiment).

  In the fifth embodiment described above, the operation of the stop mechanism 70 of the locking device 34 is released by operating the operation member 42. That is, in the fifth embodiment, the operation of the stop mechanism 70 of the locking device 34 is mechanically released. That is, in the fifth embodiment, the stop mechanism release mechanism 100 shown in FIGS. 16 to 18 is a stop mechanism manual release mechanism that manually releases the operation of the stop mechanism 70.

  As shown in FIG. 16, the locking device 34 is also provided with a stop mechanism automatic release mechanism 80 that automatically releases the operation of the stop mechanism 70 by an electrical signal.

  That is, in this embodiment, the operation of the stop mechanism 70 of the locking device 34 is electrically released by the stop mechanism automatic release mechanism 80.

  As shown in FIG. 16, the stop mechanism automatic release mechanism 80 includes a solenoid 81, a lock release lever 82 for releasing the lock state of the lock member 60 maintaining the horizontal posture, the solenoid 81, It comprises a connecting member 83 for connecting the locking release lever 82 and a locking release spring 86 for biasing the release of the state in which the locking member 60 maintains the horizontal posture.

  As shown in FIG. 27, a push button type operation button 50 is arranged on the side wall 46, and this operation button 50 is connected to the solenoid 81 via a lead wire 81E.

  As shown in FIG. 16, the solenoid 81 is provided inside a coil 81 </ b> A that is excited by an electric signal (DC24V) supplied through the lead wire 81 </ b> E when the operation button 50 is operated, A slidable plunger 81C having a tapered tip and a stopper 81B having a substantially tapered recess so that the tip of the plunger 81C is inserted.

  Since the coil 81A of the solenoid 81 supplied with 24V DC through the lead wire 81E is excited by the operation of the operation button 50, the plunger 81C that is separated from the stopper 81B inside the solenoid 81 is attracted to the stopper 81B, and the arrow O Slide in the direction. Thereby, the front-end | tip part of plunger 81C is inserted in the hollow part of the stopper 81B.

  At this time, the connecting member 83 connected to the plunger 81C also slides in the direction of the arrow O at the same time, and the locking release lever 82 formed with the protrusion 82E protruding from the opening 83A of the connecting member 83 is also connected. When pulled by the member 83, the lock release lever 82 swings about the swing center shaft 82D. Therefore, among the latch release levers 82, the quarter-circle portion 82A swings in the direction of arrow G, the semi-circle portion 82B swings in the direction of arrow J, and the protrusion 82C swings in the direction of arrow K.

  That is, the locking release lever 82 connected to the plunger 81C via the connecting member 83 starts swinging around the swing center shaft 82D of the semicircular portion 82B, and the protruding portion 82C of the locking release lever 82 19 slides in the direction of arrow a as shown in FIG. 19 and contacts the downwardly extending portion 71B of the arm member 71.

  As described above, in this embodiment, when the operation button 50 is operated, the locking release lever 82 performs the same operation as the operation of the first operation lever 101 in the fifth embodiment described above. .

  Thereby, the operation of the stop mechanism 70 is released, and as a result, the blocking body 11 starts to descend due to its own weight.

  As shown in FIGS. 16 and 17, a spring 81 </ b> D is attached to a portion of the outer periphery of the plunger 81 </ b> C of the solenoid 81 that is exposed from the case of the solenoid 81. The left end of the spring 81D is in contact with the case of the solenoid 81, and the right end is in contact with the left end of the connecting member 83. As shown in FIG. 16, when the plunger 81C slides in the direction of arrow O, the spring force in the direction of arrow P is accumulated in the spring 81D (see also FIG. 18).

  As shown in FIG. 20, a micro switch 93 is disposed below the lever member 91, and while the locking member 60 maintains the horizontal posture, the micro switch 93 faces downward due to the spring force of the spring 92. The state in which the lower surface of the bottom portion 91B of the lever member 91 in the swinging posture is in contact with the distal end portion 93C of the actuator 93A of the micro switch 93 is maintained. That is, the tip 93C of the actuator 93A of the micro switch 93 is pushed down to the lower surface of the bottom 91B of the lever member 91 by the spring force of the spring 92 and maintains the horizontal posture (in other words, the micro switch 93 is inoperative). State).

  As shown in FIG. 22, when the operation of the stop mechanism 70 is released, the lower surface of the bottom 91B of the lever member 91 is pushed up in the arrow j direction by the pin 63 of the locking member 60 pushed up in the arrow e direction. The tip 93C of the actuator 93A of the micro switch 93 is separated from the lower surface of the bottom 91B of the lever member 91 that has been in contact. At this time, the lower end 92C of the spring 92 is also pushed up in the arrow k direction.

  For this reason, the micro switch 93 is activated, and the micro switch 93 cuts off the DC 24V supplied to the solenoid 81. As a result, the coil 81A of the solenoid 81 is in a non-excited state. As a result, as shown in FIG. 18, the plunger 81C, whose tip is inserted into the recess of the stopper 81B, slides in the direction of arrow P shown in FIG. 16 due to the spring force of the accumulated spring 81D, and returns to its original position. At the same time, the locking release lever 82 connected to the plunger 81C via the connecting member 83 also returns to the original position.

  In the present embodiment, the state in which the horizontal posture is maintained is released by the stop mechanism automatic release mechanism 80, and the locking member 60 that has been in the downward swinging posture is moved to the stop mechanism 70 by the raised blocking body 11. Since the operation until the locking member 60 is maintained in the horizontal posture again is the same as in the fifth embodiment described above, description thereof is omitted.

  When the stop mechanism 70 is actuated by the raised blocking body 11, the pin 63 moving in the direction of the arrow o on the opposite side of the bracket 76 in FIG. The upper end portion 86B is pushed down in the direction of the arrow s, and the spring force in the direction opposite to the direction of the arrow s, that is, the spring force in the direction of pushing the pin 63 obliquely upward is accumulated in the unlocking spring 86. . Further, the lever member 91 has a lower end portion 92C of the spring 92 that is moved by the spring force in the arrow u direction accumulated in the spring 92 as the pin 63 of the locking member 60 moves in the arrow o direction. The upper surface of the bottom portion 91B is pushed down. As a result, as shown in FIG. 20 described above, the tip 93C of the actuator 93A of the micro switch 93 is pushed down to the lower surface of the bottom 91B of the lever member 91 that has swung in the direction of the arrow t, and the horizontal posture is maintained. (In other words, the microswitch 93 is inoperative).
