  The present invention relates to an automatic gate device installed at an entrance / exit of a pay facility or an entrance / exit of a facility that needs to manage the entrance / exit, or at a ticket gate of a station or an entrance / exit of a store.

  2. Description of the Related Art Conventionally, there is known an automatic gate device in which a gate door that can be opened and closed in both the inside and outside directions (in the range of 180 degrees) from a closed position that blocks a passage is provided on a device main body frame that forms a passage. For example, in Japanese Patent Laid-Open No. 8-86170 (Patent Document 1), a rotating shaft is provided in an upright posture adjacent to a passage, and a base end of a gate door is supported on the rotating shaft, and the rotating shaft is connected to the gate. There is disclosed a gate device that is rotationally driven so that the door takes a posture of closing the passage perpendicular to the passage in a range of 180 degrees in the horizontal direction and opening the passage parallel to the passage. Similarly, in Japanese Patent Application Laid-Open No. 11-270228 (Patent Document 2) and Japanese Patent Application Laid-Open No. 9-41854 (Patent Document 3), the gate door is orthogonal to the passage from the closed position to the inside and outside of the passage. An apparatus for automatically opening and closing is disclosed. Since these conventional devices open both inward and outward, the gate door is opened in the direction in which the entrance / exiters (pedestrians) pass through the aisle, so it is possible to ensure the safety and trafficability of the entrance / exit. It will improve.

JP-A-8-86170 JP-A-11-270228 Japanese Patent Laid-Open No. 9-41854

However, all of the above-described conventional devices have a structure in which the base end portion of the gate door is directly attached to the rotation shaft, and the gate door is rotated about the rotation shaft by driving the rotation shaft. A drive mechanism such as a rotating shaft is provided in the apparatus main body frame forming the passage. The gate door is provided at a central portion of the apparatus main body frame, more specifically in a substantially intermediate portion in the inner and outer directions (depth direction) of the passage. Arranged.
Therefore, if the length corresponding to the width of the gate door is not secured for the depth of the apparatus main body frame, the gate door protrudes from the apparatus main body frame (case) as shown in FIG. In addition to impairing the above appearance, it becomes an obstacle for people in the vicinity of the gate, and if it is to be avoided, as shown in FIG. 2 of Patent Document 2 or FIG. In other words, the depth of the case) is inevitably long, the apparatus becomes larger than necessary, and the installation floor area increases.

In view of the above circumstances, the present invention, in order to eliminate the conventional problems, by ensuring a structure that can be folded and extended between the turning member attached to the rotating shaft of the gate door, An object of the present invention is to reduce the size of the apparatus and to reduce the installation floor area by making it possible to shorten the apparatus main body frame.
In addition to the above, since the gate door is folded while rotating in either the inside or outside direction when opening, it is necessary to determine the direction of the rotation side more reliably than the conventional device at the beginning of opening, It is an object of the present invention to provide an automatic gate device that secures smoothness of an opening operation by providing assist means for assisting opening movement in either one of the inside and outside.

To achieve the above object, the present invention provides an automatic gate device in which a gate door that can be automatically opened and closed from the closed position that blocks the passage to the inside and outside of the device body frame that forms the passage is provided in the device body frame. And a pair of upper and lower guide rails extending inward and outward of the passage, and a gate member is rotatably attached to a turning member extending from the turning shaft. A roller provided at the base end of the door is guided to the guide rail so that the gate door can be opened and closed while rotating with respect to the turning member by driving the rotation shaft. In the vicinity of the base end portion, there is provided assist means for pressing the base end portion at the start of the opening operation and assisting the rotation of the gate door in either the inside or outside direction (Claim 1).
That is, the automatic gate device of the present invention is a rotary slide system that rotates between the swivel member while sliding the base end portion of the gate door along the guide rail. In view of the extending structure, it is a kind of folding door system, and is characterized by providing assist means for assisting the turning force at the start of the opening operation of the gate door rotating from the closed position.

  According to the present invention, the gate door in the closed position is pressed by the assist means at the base end portion, so that even if the gate door is opened in any direction, the initial activation is guided and smoothly rotated. In the subsequent opening operation, it is folded while rotating with the pivoting member, so that the base end is guided by the guide rail and moves in the direction opposite to the opening direction of the gate door. It is arranged in a state substantially parallel to the apparatus main body frame in such a posture that the substantially intermediate portion is on the closed position line.

The assist means is not particularly limited as long as the assist means presses the base end portion of the gate door and assists rotation in either the inside or the outside, but as a specific form, the assist means Is formed of a set of two pieces arranged at intervals on the rotating shaft, and the upper and lower assist means include a pressing member that presses the base end portion of the gate door at an angle opposite to that of the gate door. It is characterized (claim 2). According to this, since the assist means is attached to the rotating shaft, the support member is not required and the arrangement space is reduced, and the two pressing members share the pressing force in the inner direction and the pressing force in the outer direction. Can function.
Preferably, the pressing member of each of the assist means is usually spaced from the base end portion of the gate, and is pressed against the base end portion of the gate door when the gate door opening operation starts. (Claim 3). Thereby, when one pressing member presses the base end portion of the gate door, it can be avoided that the other pressing member becomes a resistance.

The gate door is rotatably attached to the turning member. As a preferred form of the turning member and the gate door, the turning member has a rectangular shape when viewed from the front, and the gate door is formed of the turning member. The upper arm plate and the lower arm plate extending to the upper side and the lower side, and the upper arm plate and the lower arm plate are pivotally attached to the upper and lower parts of the free end side of the turning member by a hinge. The roller is arranged on the base end side, and a pressure receiving surface that engages with the pressing member of the assist means is formed (claim 4). According to this, the gate door is rotatably arranged on the free end side of the turning member extending from the rotating shaft, and the upper space of the upper arm plate of the gate door and the lower space of the lower arm plate, that is, the turning which is a movable member. Guide rails can be disposed outside the member and the gate door, and the distance between the upper and lower pressure receiving surfaces that engage with the pressing member can be increased.
In addition, as another form, it is also arbitrary that the revolving member is made of two members in the shape of a thin plate separated vertically, and the gate door is rotatably attached by hinges between the upper and lower revolving arm plates. .

More specifically, in relation to the assist means, the pressure receiving surfaces of the upper arm plate and the lower arm plate are formed as inclined surfaces facing inward and outward, and the pressing member of each assist means is connected to the upper arm plate and the lower arm plate. Each pressure receiving surface is abutted orthogonally (Claim 5), and more preferably, a roller is provided at the tip of each pressing member, and the roller abuts each pressure receiving surface of the upper arm plate and the lower arm plate. (Claim 6).
According to this, the assisting means can efficiently transmit the pressing force urging at the initial rotation of the gate door, with the pressing member abutting perpendicularly to the pressure receiving surface of the gate door. When the gate door rotates, the roller of the pressing member separates while rolling on the pressure receiving surface.

  The gate device has a two-door structure in which a passage is formed between two device body frames as in Patent Document 1, or one device body frame and a barrier as in Patent Document 2 or Patent Document 3. Can be applied to any single door structure that forms a passage, but preferably the former structure in which the passage width can be increased, that is, the passage by arranging two of the apparatus main body frames at intervals. The gate doors are arranged symmetrically on both device body frames, the passage is closed by the two gate doors, and at the same time, the passage is opened by automatically opening and closing both inward and outward from the closed position. (Claim 7).

According to the first aspect of the present invention, at the open position of the gate door with the passage opened, the apparatus main body frame is substantially parallel to the apparatus main body frame in a posture in which a substantially intermediate portion of the gate door is on the closed position line. If the depth length is set to a length substantially corresponding to the width of the gate door, the gate door in the open position can be accommodated without protruding from the apparatus body frame. Therefore, the apparatus main body frame can be made shorter and smaller than the conventional apparatus without deteriorating the appearance of the apparatus, and the installation floor area of the apparatus can be reduced.
Further, although the gate door is an opening type that is folded while rotating, the assisting means assists the turning force at the start of the opening operation, so that it is possible to provide an automatic gate device that ensures the smoothness of the opening operation.

  According to the second aspect of the present invention, a dedicated support member for attaching the assist means is not required, and the fit around the rotating shaft can be improved, and the two pressing members share both internal and external pressing forces. Therefore, the operation of the assist means can be ensured, and according to claim 3, when one pressing member presses the base end of the gate door, the other pressing member becomes a resistance. Since it avoids, operation | movement of an assist means can be performed more reliably.

  According to the fourth aspect of the present invention, the guide rail can be provided with a margin at which the base end portion of the gate door is slid, and the distance between the upper and lower pressure receiving surfaces engaged with the pressing member can be increased. In addition, the space between the upper and lower assist means disposed on the rotation shaft can be provided with a sufficient margin within the apparatus main body frame. Further, according to the fifth and sixth aspects, the pressing force by the assisting means that is urged when the gate door is initially rotated can be efficiently transmitted, and the roller of the pressing member can be transmitted when the gate door is subsequently rotated. The gate door can be opened more smoothly, for example, while the pressure contact surface rolls apart.

  According to the seventh aspect of the present invention, it is possible to provide an automatic gate device having a small feeling as a whole while ensuring a large passage width.

The embodiment of the present invention will be described with reference to the drawings.

If a plurality of sets of automatic gate devices A are arranged as necessary, a plurality of gate passages are formed at the entrance / exit.

  The details of the automatic gate device A will be described with reference to FIGS. 4 to 9. However, since the main body frames 1 and 1 have the same configuration except that they are bilaterally symmetrical, the right main frame 1 will be described for convenience of explanation. The same members of the other body frame 1 are denoted by the same reference numerals, and detailed description thereof is omitted.

The main body frame 1 is a hollow frame having a substantially rectangular shape whose depth is about half the height, and the inner frame plate 1a facing the passage 2 has a depth direction at a portion where the gate door 10 is disposed. The storage part 3 which is recessed over the entire length is formed so that the gate door 10 which has been moved to the open position is accommodated in the storage part 3 without protruding from the main body frame 1 (see FIGS. 4 to 6).
In the main body frame 1, as shown in FIG. 4, a base member 5 configured by raising four support legs 5 a, 5 a... On a bottom plate 4 is disposed below the storage unit 3 and stored. An upper receiving member 7 configured by hanging four suspension arms 7 a, 7 a... From the beam plate 6 is disposed above the portion 3, and a front view connection between the base member 5 and the upper receiving member 7 is arranged. A shaped support base plate 8 is disposed.

Is fixed to the outer frame plate 1b of the main body frame 1 by screws.

As shown in FIGS. 5 and 6, the support base plate 8 is disposed at a substantially intermediate portion of the main body frame 1 in a plan view, and the upper plate 8 a is spaced above the storage portion 3 as shown in FIG. 4. The lower plate 8b is arranged below the storage unit 3 with a space therebetween, and the space formed between the storage unit 3 and the outer frame plate 1b extends over the upper plate 8a and the lower plate 8b. The rotating shaft 11 is arranged upright. Further, a U-shaped guide rail 12 is mounted downward on the lower surface of the upper plate 8a, and a guide groove of the rail is arranged in an opening shape on the upper portion of the storage portion 3. The rail 13 is attached upward, and its guide groove is arranged in an opening at the lower part of the storage unit 3.
Each of the guide rails 12 and 13 has a length over the entire length in the depth direction of the main body frame 1, and is opposed to the inner vertical position of the storage unit 3.

Further, the lower plate 8b of the support base plate 8 is provided with a mounting bracket 14 on the lower surface thereof, and the driving motor M and the speed reducer 15 for the rotary shaft 11 are attached to the bracket 14, and the rotary shaft is mounted on the upper plate 8a. 11 positioning mechanisms 16 are attached.
The rotating shaft 11 is rotatably supported by bearings 17a and 17b provided on the upper plate 8a and the lower plate 8b, and the motor M uses, for example, a brushless motor and is driven by a drive shaft 15a that outputs via the speed reducer 15. The lower end of the rotating shaft 11 is coupled by a coupling 18 and electrically connected to a controller CB that controls the operation of the apparatus. The controller CB is disposed at an appropriate position in the main body frame 1 such as the base member 5.

As shown in FIGS. 4 and 7, the positioning mechanism 16 includes a rotating plate 21 that is integrally inserted into the upper end portion of the rotating shaft 11, and a swing rod 23 that is swingably mounted on the upper plate 8a. The cam floor 22 is in contact with the outer periphery of the rotating plate 21.
The swing rod 23 has a support shaft 24 at one end, a cam floor 22 is rotatably provided at the center, and a spring 25 is hooked at the other end so that the cam floor 22 is elastically biased toward the rotary plate 21. It is a thing. On the outer peripheral surface of the rotating plate 21, a first recess 26 a is provided at a fixed position serving as a base point of the rotating shaft 11, and a second recessed portion 26 b and a third recessed portion 26 c are formed at equal intervals on both sides thereof. Is in the base position, the cam floor 22 engages with the first recess 26a, and when the rotary shaft 11 rotates forward and backward and rotates a predetermined angle, the cam floor 22 becomes the second recess 26b or the third recess 26c. The stop position of the rotating shaft 11 is positioned by engaging.

One end of a revolving plate 30 having a rectangular shape when viewed from the front is fixed to the rotating shaft 11 and attached to the rotating shaft 11 so as to be rotatable at a predetermined angle. 31 and 32 are fixed and arranged.
The swivel plate 30 protrudes from the free end side into the storage portion 3, and the gate door 10 is rotatably attached to the swivel plate 30 via hinges 33a and 33b. Specifically, the gate door 10 has an upper arm plate 34a and a lower arm plate 34b that extend to the upper and lower sides of the swivel plate so as to sandwich the swivel plate 30, and are formed integrally or separately, and the upper arm plate is formed by the hinges 33a and 33b. 34a and the lower arm board 34b are attached to the turning board 30 so that rotation is possible.
The illustrated gate door 10 is a case where a hard core material 10a such as a thin metal plate is covered with an outer skin material 10b such as a soft resin, and the upper arm plate 34a and the lower arm plate 34b are connected and integrated. Illustrated.

The gate door 10 has a roller 35a attached to the upper surface of the base end portion of the upper arm plate 34a so as to be horizontally rotatable, and a roller 35b is also attached to the lower surface of the base end portion of the lower arm plate 34b. 35a and 35b are fitted to the guide rails 12 and 13 so as to be able to roll, respectively, and are guided. It should be noted that it is of course arbitrary to change to a component that can obtain an equivalent action, such as using a resin slider that can slide in the guide rail instead of the rollers 35a and 35b.
Further, the upper arm plate 34a and the lower arm plate 34b of the gate door 10 are formed with inclined end surfaces at their base end portions, and pressure receiving surfaces 36a that receive a temporary pressing force from the assist members 31 and 32, 36b, the pressure receiving surfaces 36a and 36b are formed so that the inclination directions are inward and outward, that is, the pressure receiving surface 36a is an inwardly inclined surface (see FIG. 5) and the pressure receiving surface 36b is an outwardly inclined surface (see FIG. 6). .

As shown in FIG. 8, the assist members 31 and 32 are urged in a forward direction by a spring force of a plunger 42 and a spring 43, which are projected and retracted by actuation (excitation or demagnetization) of a solenoid 41 in a housing 40. A rod 44 is provided side by side, and the plunger 42 and the pressing rod 44 are integrally connected by a connecting rod 45. A roller 46 is rotatably attached to the tip of the pressing rod 44.
When the assist members 31 and 32 are energized in a normal state, the plunger 42 is immersed due to the excitation of the solenoid 41, and the pressing rod 44 is held in the retracted position against the spring force of the spring 43 (see FIG. 8), when the solenoid 41 is demagnetized, the pressing rod 44 moves forward together with the plunger 42 by the spring force of the spring 43. When the solenoid 41 is energized, the pressing rod 44 moves together with the plunger 42 in the retracted position. Return to.

  The assist members 31 and 32 have substantially the same structure, and the rotating shaft 11 has the assist member 32 disposed on the front side of the hand and the assist member 31 turned upside down on the opposite surface side. At the same time, the assist members 31 and 32 are attached in opposite directions so that the attachment angles are symmetrical. Specifically, the assist member 31 is attached at an angle at which the roller 46 abuts perpendicularly to the pressure receiving surface 36a formed on the upper arm plate 34a of the gate door 10 (see FIG. 5), and the assist member 32 is attached to the roller 46. Is an angle that abuts perpendicularly to the pressure receiving surface 36b of the lower arm plate 34b (see FIG. 6). FIG. 8 shows the assist member 32.

The assist members 31 and 32 are normally arranged (when energized) such that the roller 46 of the pressing rod 44 is spaced apart from the pressure receiving surfaces 36a and 36b of the upper arm plate 34a and the lower arm plate 34b by a small distance, When one of the solenoids 41 is demagnetized at the start of the opening operation of the gate door 10 where the rotary shaft 11 is activated, the pressing rod 44 of the assist member moves forward, and the upper arm plate 34a or the lower arm plate 34b via the roller 46. The pressure receiving surface 36a or 36b is temporarily pressed.
In addition, although the said assist members 31 and 32 illustrated the case where the press rod 44 was advanced and depressing | moving at the time of the demagnetization of the solenoid 41, it is not limited to it, For example, the plunger 42 itself of the solenoid 41 is pressed. It is optional to directly attach the roller 46 to the plunger as a rod and change the plunger 42 to advance and perform a pressing operation when the solenoid 41 is temporarily excited.

Thus, the rotary shaft 11 rotates forward or reverse at a predetermined angle under the control of the controller CB, and when the forward rotation in the arrow direction P shown in FIG. While the door 10 is rotated by the hinges 33a and 33b, the rollers 35a and 35b provided on the upper arm plates 34a and 34b are guided by the guide rails 12 and 13 and slide in the arrow direction Q.
As the operation proceeds in synchronism with the main body frames 1 and 1 on both sides, both the gate doors 10 and 10 are folded between the swivel plates 30 and 30 while being closed from the closed position (solid line position in FIG. 2). And is accommodated in the storage units 3 and 3 to open the passage 2 (see the two-dot chain line in FIG. 2). That is, the gate doors 10 and 10 have a posture in which the passage 2 is opened so as to allow entry from the outer side 2b toward the inner side 2a. When the rotary shaft 11 rotates in the direction opposite to the arrow direction P from the open position, both the gate doors 10 and 10 are returned to the closed position while being extended between the revolving plates 30 and 30.
When the gate doors 10, 10 reach the opening position on the entrance side, the cam floor 22 is fitted in the second recess 26 b of the rotating plate 21 that rotates together with each rotating shaft 11 to position the opening posture of each gate door 10. When the rotary shafts 11 are reversed, the cam floor 22 is pushed out of the second recess 26b by the rotation of the rotary plate 21, and the cam floor 22 is fitted into the first recess 26a when each gate door 10 returns to the closed position. The closing posture of each gate door 10 is again positioned (see FIG. 7).

On the other hand, when the rotating shaft 11 reverses in the arrow direction P ′ shown in FIG. 3, the revolving plate 30 is rotated in the same direction, whereby each gate door 10 is rotated by the hinges 33a and 33b and the upper arm plate 34a. , 34 b are guided by the guide rails 12, 13 and slide in the arrow direction Q ′, so that both gate doors 10, 10 are closed between the swivel plates 30, 30 while being folded. It opens from the (two-dot chain line position in FIG. 3) to the open position and is accommodated in the storage units 3 and 3 to open the passage 2 (see the solid line in FIG. 3). That is, the gate doors 10 and 10 have a posture in which the passage 2 is opened so as to allow exit from the inner side 2a to the outer side 2b. When the rotary shaft 11 rotates in the direction opposite to the arrow direction P ′ from the open position, the gate doors 10 and 10 are returned to the closed position while being extended between the swivel plates 30 and 30.
When the gate doors 10, 10 reach the exit position on the exit side, the cam floor 22 is fitted into the third recess 26 c of the rotating plate 21 that rotates together with each rotating shaft 11 to position the opening posture of each gate door 10. When the gate doors 10 are returned to the closed position due to the reversal of the rotary shafts 11, the cam floor 22 is fitted into the first recess 26a, and the closed posture of the gate doors 10 is again positioned (see FIG. 7).

The assist action at the beginning of normal rotation or reverse rotation of the rotating shaft 11, that is, at the start of the opening operation on the entrance side or the exit side of the gate door 10, is shown in FIG. 5 in the case of the entrance side opening operation corresponding to FIG. This will be described with reference to FIG.
The start / stop of the motor M for driving the rotating shaft 11 and the demagnetization / excitation of the solenoids 41, 41 of the upper and lower assist members 31, 32 are controlled by the controller CB. For example, it starts in response to a detection signal of a reader (for example, a card reader) for checking a traffic check card, an admission ticket, etc., and activates the assist member 31 at the same time as or before the motor M is started. To.
Specifically, the solenoid 41 of the assist member 31 is demagnetized by the detection signal of the entrance reader, and the pressing rod 44 of the assist member 31 is advanced to move the roller 46 to the upper arm plate 34a of the gate door 10 as shown in FIG. The pressure receiving surface 36a is abutted against the pressure receiving surface 36a to press the pressure receiving surface 36a, thereby energizing the gate door 10 with the rotational force about the hinges 33a and 33b as a support shaft and applying the roller 35a of the upper arm plate 34a in the arrow direction Q. Rush. Thereby, the gate door 10 and the swivel plate 30 that are connected in a straight line in the closed position are easily bent by the hinges 33a and 33b, and the rotation of the gate door 10 accompanying the normal rotation of the rotary shaft 11 is subsidized. The opening direction of the gate door 10 is guided.

In the initial rotation of the rotating shaft 11, the lower assist member 32 keeps the solenoid 41 excited as shown in FIG. 6, and the roller 46 of the pressing rod 44 is separated from the pressure receiving surface 35b of the lower arm plate 34b. Therefore, there is no load on the rotational force of the gate door 10 subsidized by the assist member 31, and the assist members 31, 32 are disposed on the rotary shaft 11 and rotate integrally. They do not become an obstacle during the rotation.
Note that the timing at which the roller 46 of the pressing rod 44 and the pressure receiving surface 36a of the upper arm plate 34a abut each other does not necessarily have to be the same as the start of the motor M that rotates the rotary shaft 11, and there is a slight slow speed before and after that. Of course, the timing may be different.

  5 and 6, the case of the entrance-side opening operation corresponding to FIG. 2 has been described. However, in the case of the exit-side opening operation corresponding to FIG. 3, the rotating shaft 11 is reversed (rotation in the arrow direction P ′). When the pressure rod 44 of the assist member 32 moves forward, the roller 46 abuts against the pressure receiving surface 35b of the lower arm plate 34b and presses, and the roller 46 of the assist member 31 moves away from the pressure receiving surface 35a of the upper arm plate 34a. Since the rest is the same as the entrance side opening operation, detailed illustration and description are omitted.

Then, after the initial rotation of the rotating shaft 11 accompanied by the assist operation by the assist member 31 or 32, as described above, the entrance side opening / closing operation of FIG. 2 or the exit side opening / closing operation of FIG. 3 is performed.
4 and FIG. 7 is an upper sensor for projecting and receiving light toward the passage 2, and S2 is a lower sensor. The sensors S1 and S2 indicate whether or not a passerby exists in the passage 2. In this case, the activation of the closing operation of the opened gate doors 10 and 10 is prohibited when a passerby is detected.

In the above embodiment, the gate door 10 and the swivel plate 30 are configured such that the upper arm plate 34a and the lower arm plate 34b are formed on the gate door 10 to sandwich the swivel plate 30, but the present invention is not limited thereto. It is good to change suitably, for example, it is good as a structure shown in FIG.
In FIG. 10, a base end plate 34 ′ having a reduced height is formed integrally or separately on the gate door 10 ′, and the swivel plate is divided into an upper swivel plate 30a and a lower swivel plate 30b. Both the swivel plates 30a and 30b are arranged on the upper side and the lower side of the base end plate 34 ', and are attached rotatably by hinges 33a and 33b.
In relation to the above change, the guide rails 12 and 13 are attached and supported by a plurality of upper and lower stays 37a and 37b fixed to the support base plate 8, and the base end plate 34 'of the gate door 10' is attached to the base end plate 34 '. The pressure receiving surface 36a 'and the pressure receiving surface 36b' are formed in the upper half and the lower half so that the inclined directions are opposite to each other, and these end faces are formed on the rollers 46, 46 of the assist members 31, 32, respectively.
