Detailed description

Features of the invention will be described in conjunction with a number of specific and alternative embodiments. However, it will be apparent to those skilled in the art that the present invention may be practiced without these specific features. Some features may not be described in order to avoid obscuring the invention. For ease of reference, the same reference numerals are used in the drawings to represent the same or similar devices.

1 shows a perspective view of a barrier 100 that includes a barrier baffle 102 in accordance with an embodiment of the present invention. The barrier 100 is built into a housing (not shown). Basically, when placed along the same horizontal axis, the two relatively positioned barriers 100 form an access gate. The access gate allows or restricts the user from entering an area or space, and thus requires any form of authorization to open the entry and exit. Systems and methods suitable for provisioning and authorizing access through the access are well known in the art and, therefore, are not described herein.

The barrier 100 includes a motor assembly 101, a barrier baffle 102, a bearing support portion 103, an adjustable rod 104, a baffle lever joint 105, a resilient member (not shown), a guide support portion 107 and a metal base. Frame 108. The motor assembly 101, the barrier baffle 102, the bearing support portion 103, the adjustable lever 104, the baffle lever joint 105, the elastic member and the guide support portion 107 in the barrier 100 are loaded in a housing (not shown) of the access gate . In an embodiment, the resilient member can be a tension spring or a force spring, such as a coil spring.

Motor assembly 101 is a motor assembly that is provided with an integrated control unit (not shown). The barrier baffle 102 is a barrier used in the access gate that pivots back and forth over the metal base frame 108, thereby causing the barrier 100 to remain in an open or closed position. To avoid guessing, when the barrier baffle 102 is retracted toward the motor assembly 101, the barrier 100 is in the open position, and when the barrier baffle 102 is pivoted outward from the motor assembly 101, the barrier 100 is in the closed position. The barrier baffle 102 is coupled to and supported by a metal rod 110 that is pivoted over the metal bottom frame 108 by a bearing support 103. The bearing support portion 103 reduces friction and reduces noise generated by the pivotal movement of the barrier shutter 102. One end of the adjustable rod 104 is coupled to a proximal end of the metal rod 110 that supports the barrier baffle 102, and the other end is coupled to the baffle lever joint 105. The length of the adjustable rod 104 can be adjusted to control the stroke length of the barrier baffle 102. The lower distal end of the metal rod 110 is pivotally coupled to the bearing support portion 103, while the upper distal end is supported by the guide support portion 107, wherein the upper distal end rotates along the guide support portion 107. The baffle lever joint 105 is generally an L-shaped connector that is coupled to the motor assembly 101 at its curved corner. The motor assembly 110 drives the baffle lever joint 105 to operatively rotate in a clockwise and counterclockwise direction about the curved corner. The other distal end of the baffle lever joint 105 is pivotally coupled to the adjustable rod 104 as described above. The other end of the baffle lever joint 105 extending outward from the curved corner serves as a stop arm that restricts rotation of the baffle lever joint 105. The adjustable rod 104, the baffle lever joint 105 and the metal rod 110 are interconnected with the metal bottom frame 108 supporting the metal rod 110 and the baffle lever joint 105 to form a four-bar linkage set, which will be described in detail below. . The guiding support 107 guides the opening or closing of the barrier shutter 102 in the barrier 100 stroke.

The barrier baffle 102 only moves back and forth between the open and closed positions of the barrier 100 in a two-way manner. The elastic member has one end connected to the metal rod 110 and the other end connected to the bottom frame 108. When the barrier baffle 102 is in the closed position on the barrier 100, the resilient element extends. However, when the motor assembly 101 loses power, it pulls the barrier baffle 102 back to drive the barrier baffle 102 rearward. Further, the barrier baffle 102 of the present invention is a wing-like baffle having an outer curved length that is curved. In the barrier 100, only a single piece of wing-like baffle is used as the barrier baffle 102.

Still referring to FIG. 1, a motor assembly 101 in accordance with an embodiment of the present invention includes an electric motor and a gear assembly that drives the baffle lever joint 105. To save space, the motor assembly 101 is oriented vertically on the metal bottom frame 108 such that the baffle lever joint 105 is driven horizontally. Therefore, the gear assembly is adapted to convert the vertical drive force to a horizontal force. The motor assembly 101 connects the barrier 100 in a reciprocating direction, that is, retracts the barrier baffle 102 inwardly when the barrier 100 is in the open position, or outwardly drives the barrier baffle 102 when the motor assembly barrier 100 is in the open position. .

The integrated control unit in the motor assembly 101 reduces the number of wires required for the barrier 100, making the barrier 100 simpler and easier to repair, and reducing the grounding area of the overall structure of the barrier 100. In addition, the integrated control unit controls the motor assembly 101 that drives the baffle lever joint 105. The integrated control unit continuously switches the phase of the current in the electric motor as the electric motor drives the baffle lever joint 105 forward and backward on a single shaft. The forward movement of the baffle lever joint 105 causes the barrier baffle 102 to outward Extending, and the rearward movement of the baffle lever joint 105 causes the barrier baffle 102 to retract inwardly.

The motor assembly 101 is adapted to angularly drive the baffle lever joint 105 through the gear assembly. The gear assembly includes a satellite gear followed by a helical gear. The satellite gear reduces the rebound of the motor assembly 101, providing better overall efficiency. The rebound is the amount of lost motion due to the gap or slack when the steering is moved and the contact relationship is established again. The bounce of the barrier 100 is created by the pivotal movement of the barrier baffle 102. The satellite gears provide greater stability in the motor assembly 101 and the load of the electric motor is evenly distributed. The helical gear used in the gear assembly can be a bevel gear. The helical gear is a pair of helical gears adapted to change a driving direction at 90° or a right angle. Therefore, the bevel gear is adapted to drive the baffle lever joint 105 at an angle.

Therefore, the configuration of the gear assembly and the electric motor is compared with the conventional DC motor for driving the horizontally placed access gates, and a more space-efficient configuration is provided. The gear assembly of the motor assembly 101 is secured to a metal frame 108 where the helical gears in the gear assembly are coupled to the baffle lever joint 105. When the barrier baffle 102 extends outwardly, the motor assembly 101 drives the baffle lever joint 105 forward on a single shaft. When the barrier baffle 102 is retracted inwardly, the motor assembly 101 is on the same single shaft, driving the baffle lever joint 105 rearwardly.

In the above embodiments, the motor assembly 101 can include any suitable electric motor to operatively drive the barrier baffle 102. The electric motor may include a direct current motor, a brushed direct current motor, a brushless alternating current motor, and the like.

When the barrier baffle 102 is in the open and closed position of the barrier 100 When turning, it moves bidirectionally, and pivots around the bearing support portion 103 on a horizontal axis. The barrier 100 must be sufficient to withstand the friction caused by constant movement due to the need to accommodate users with more flow into and out of the gate. Therefore, in an embodiment of the present invention, the bearing support portion 103 is provided to reduce the frictional force caused by the frequent movement of the barrier 100. Further, the noise caused by the movement of the barrier damper 102 (when it is moved to the open or closed position) is reduced by the bearing support portion 103.

One end of the adjustable rod 104 is erected to the metal rod 110 of the barrier baffle 102. The length of the adjustable rod 104 controls the stroke length of the barrier baffle 102, thus providing the entire stroke length of the barrier baffle 102 suitable for the barrier 100. When the two barriers 100 are placed opposite each other along the same horizontal axis, the entire stroke length of the barrier baffle 102 provides a barrier that allows or prevents passage of the user. Due to the adjustability of the entire stroke length of the barrier baffle 102, the distance between the positions of the two opposing barriers 100 is not limited.

Additionally, the other end of the adjustable lever 104 is erected to a baffle lever joint 105 that is operatively driven for the motor assembly 101. Thus, the baffle lever joint 105 drives the adjustable lever 104 to pivot about the metal bar 110 of the barrier baffle 102. Additionally, the baffle lever joint 105 can be adjusted to a self-locking mechanism to prevent the baffle lever joint 105 from moving in any other direction than pivoting about its pivot point.

The guide support portion 107 guides the stroke of the pivotal movement of the barrier damper 102. The guide support portion 107 reduces lateral vibration generated by the opening and closing movement of the barrier shutter 102. Therefore, the guide support portion 107 increases the stability of the entire movement of the barrier shutter 102 in the barrier 100. In addition, the guide support unit 107 The radial load factor of the barrier 100 is improved. The radial load factor affects the overall force due to the torque (force) transmitted by the gear assembly. The improved radial load factor can provide primary support for the barrier 100 to withstand the external forces exerted on the barrier baffle 102 (up to 100 J), but still maintain the function of the barrier 100. This modification also allows the metal rod 110 that is erected to the barrier baffle 102 to be lighter and thinner than conventional designs. Conventional designs require a heavier or more stable erection to the metal rod of the barrier baffle 102 to prevent forced entry through the access gate.

The barrier 100 in the closed position is shown in Figure 1. When the barrier baffle 102 is driven outward, the resilient element extends. The extension of the resilient element depends on the length of the adjustable rod 104 that is erected to the baffle lever joint 105. The longer the length of the adjustable rod 104, the more the barrier flap 102 can extend outwardly, so that the elastic element can be extended longer. When the motor assembly 101 drives the resilient member outwardly, the resilient member also provides a return force toward the barrier baffle 102, thus making it difficult for the barrier 100 to be forcibly separated. Furthermore, by means of the guiding support 107, the barrier flap 102 is forced to move only along the rail, further preventing the barrier flap 102 from being forcibly opened.

The resilient member is erected to the barrier barrier 102 and extends the length of the barrier 100 when it is in the closed position. When power supply or other possible emergency conditions occur, the barrier 100 ceases to operate, and thus, the resilient element returns the barrier baffle 102 to the open position of the barrier 100. In this way, the user who is allowed to enter and exit is allowed to pass through the brake quickly. When the resilient element is maintained in an extended condition (the resilient element is unable to function), the user can force the barrier baffle 102 into the housing inwardly. I have to pass through the gate.

When the user is passing through the barrier 100, if the barrier is 102 Extending outwardly, it hits the user, thereby blocking the pivotal movement of the barrier baffle 102. The integrated control unit in the motor assembly 101 monitors the time required for the barrier baffle 102 to fully extend outward or fully retract inward. The integrated control unit activates a blocking detection function when the barrier baffle 102 extends completely outward or is fully retracted in time. When the blocking detection function is turned on, the integrated control unit controls the motor assembly 101 to retract the barrier baffle 102 completely inwardly. This reduces the chance of injury to the user.

In the event that an unauthorized user forces the barrier 100 to be opened, the motor assembly 101 can also be operated to provide any opposing force that is applied to the barrier baffle 102 by an unauthorized person attempting to use the access gate. The integrated control unit in the motor assembly 101 controls the current setting of the electric motor so that the amount of power delivered by the electric motor to the barrier baffle 102 can be controlled.

The metal bottom frame 108 supports the members constituting the barrier 100, and the bottom thereof is fixed to the ground to form a stable structure of the barrier 100, and the bearing support portion 103 is mounted on the metal along the same vertical axis as the interior of the barrier shutter 102. On the bottom frame 108. At this point, the metal rod 110 of the barrier baffle 102 pivots about a bearing support 103 on a horizontal axis to position the barrier 100 in the open and closed positions. The metal bottom frame 108 extends upwardly from its bottom and supports the length of the metal rod 110 of the barrier baffle 102. The guide support portion 107 is mounted on the metal bottom frame 108 with respect to the distal end of the bearing support portion 103. One end of the adjustable rod 104 is erected to the middle of the metal rod 110 of the barrier baffle 102. The other end of the adjustable lever 104 is erected to the baffle lever joint 105, and the baffle lever joint 105 is erected to the gear assembly of the motor assembly 101. The motor assembly 101 drives the baffle lever joint 105; thus driving the adjustable lever 104, The barrier baffle 102 is pivoted in the field. The baffle lever joint 105 is specifically placed between the motor assembly 101 and the metal bottom frame 108. Further, the motor assembly 101 is mounted on the inner corner of the metal bottom frame 108 beside the bearing support portion 103.

When the barrier baffle 102, the adjustable lever 104, and the baffle lever joint 105 are erected together on the metal base frame 108, a configuration similar to a four-bar linkage is formed. The configuration of each member will be described below in conjunction with Figures 3A-3B.

Figure 2 shows a perspective view of the barrier 100 in an open position. In the open position, the barrier baffle 102 is retracted inwardly into the housing of the barrier 100. The integrated control unit in the motor assembly 101 operatively switches the phase of the current in the electric motor to retract the barrier baffle 102 inwardly to the open position.

The location of the various components in the barrier 100 allows the entire structure including the barrier baffle 102 to be secured in the housing (not shown) when the barrier 100 is in the open position. When the resilient member (not shown) returns to its original length, the barrier flap 102 is guided inwardly along the guide support portion 107.

Fig. 3A shows the structure of the barrier 100 in Fig. 1. The structure of the barrier 100 is generally a four-bar linkage 300 that rotates the barrier baffle 102 about the bearing support 103. In the four-bar linkage 300, the motor assembly 101 upper baffle lever joint 105 is mounted as a primary lever 302 in a static position on the metal base frame 108. The other end of the adjustable lever 104 pivots on the barrier lever joint 105 as a secondary lever 303. Then, the metal rod 110 supporting the barrier baffle 102 is pivotally supported on the metal bottom frame 108 with its lower distal end and is erected to the other end of the adjustable rod 104 along the center of the metal rod 110. The metal rod 110 acts as a tertiary rod 304 of the four-bar linkage 300. The bottom frame 301 supporting the bearing support portion 103 and the baffle lever joint 105 (through the motor assembly 101 mounted thereon) form a bottom bar 301 of the four-bar linkage 300.

The bottom bar 301 includes two fixed points in the four bar linkage 300. One end of the bottom rod 301 is a bearing support portion 103, and the bearing support portion 103 is mounted on the metal bottom frame 108. The other end of the bottom rod 301 is in a static position that is erected to the primary rod 302 of the motor assembly 101.

The primary rod 302 is configured to rock a crank of the tertiary rod 304 through the secondary rod 303. Two stops 305 are erected on the metal bottom frame 108 to restrict the primary rod 302 from rotating freely about the motor shaft. In particular, the primary rod 302 is constrained to rotate over a limited stroke length. The stroke length of the primary rod 302 is determined by the length of one stroke required for the tertiary rod 304.

One end of the secondary rod 303 is erected to the primary rod 301 and the other end is erected to the tertiary rod 304. The length of the secondary rod 303 can be adjusted, which can be used to adjust the entire stroke length of the tertiary rod 304 as needed.

A spring connector 307 is provided on the tertiary rod member 304 at a position that is close to the point at which the end of the secondary rod member 303 is placed. The spring connector 307 allows one end of the elastic element as shown in FIG. 1 to be erected to the tertiary rod 304 in the barrier 100. The other end of the resilient member is erected to a corner of the primary member 302 and the primary member is erected to the other spring connector 307.

In this example, the four-bar linkage 300 is generally a crank rocker linkage where the length of the primary linkage 302 is the shortest and the tertiary rod 304 is rocked in a curved arc 309. Four rods are known in the art of skill The different lengths and connection points control the movement of the four-bar linkage 300.

3B is a schematic diagram of a four-bar linkage 300 of the barrier 100 of FIG. 3A including a bottom bar 301, a primary bar 302, a secondary bar 303, and a tertiary bar 304.

Each of the bottom bars 301 is represented by a circle to indicate a fixed point of the bottom bar 301. A first fixed point 308 of the bottom bar 301 is the bearing support portion 103 and a second fixed point 310 is in the static position of the baffle lever joint 105. The bottom bar 301 is the only one of the four bar linkages 300 that is maintained in its static position and that does not rotate in any direction.

The primary rod 302 has the shortest length in the four-bar linkage 300. As shown in FIG. 3A, the baffle lever joint 105 is erected to the motor assembly 101, and the adjustable lever 104. One end of the primary rod 302 is erected to the second fixed point 310 of the bottom rod 301, and the other end of the primary rod 302 is erected to one end of the secondary rod 303. The primary rod 302 rotates along a same curved axis following a small curved arc 306. The rotation of the primary rod 302 around the second fixed point 310 is limited by the stop 305.

The secondary rod 303 is an adjustable rod 104 as shown in Fig. 3A. The other end of the secondary rod 303 is erected to one end of the tertiary rod 304. The other end of the tertiary rod 304 is pivotally connected to the first fixed point 308 of the bottom rod 301.

When the barrier 100 is in the open position, the barrier baffle 102 is retracted into the barrier 100. When the barrier 100 is moved to its closed position in its open position, the barrier baffle 102 extends outwardly. Point A represents the point at which the secondary rod 303 and the tertiary rod 304 are erected when the barrier 100 is in the open position. Point B represents that the secondary rod 303 and the tertiary rod 304 are erected when the barrier 100 is in the closed position. Point.

When the barrier 100 is moved from its open position to its closed position, the primary lever 302 simultaneously shakes the tertiary rod 304 through the secondary rod 303. The tertiary rod 304, or more specifically, the barrier baffle 102, moves from point A to point B along the curved arc 309.

4 is a perspective view of a barrier 400 including a retractable barrier 401 in a closed position in accordance with another embodiment of the present invention. The barrier 400 includes a telescoping baffle 401, a motor assembly 402, a guiding support portion 403, a bearing support portion 404, a telescoping baffle lever joint 405, a lever member 406, and a resilient member (not shown). And a metal bottom frame 407. The difference between the barrier 400 in FIG. 4 and the barrier 100 in FIG. 1 is the type of the baffle lever joint (the baffle lever joint 105 and the telescopic baffle lever joint 405), the barrier (the barrier baffle 102 and the telescopic baffle) The type of 401) and the configuration of the integrated control unit in the motor assembly. The guide support portion 403, the bearing support portion 404, and other members of the elastic member are substantially identical. The resilient element also extends as the telescoping flap 401 extends outwardly.

The retractable baffle 401 in the barrier 400 differs from the barrier baffle 102 in the barrier 100 in that the barrier 400 includes a retractable baffle 401 having a housing 408 and an inner core baffle 409. This configuration of the telescoping baffle 401 allows for a wider gap (compared to the barrier 100) between the corresponding barriers 400. This configuration of the telescoping baffle 401 also allows for protection of a wider area such that a wider item passes between two corresponding barriers or an authorized person can pass through the access. The retractable baffle 401 extends outwardly when the barrier 400 is in its closed position and retracts inwardly when the barrier 400 is in its open position.

In another embodiment, the telescoping flap 401 can include a plurality of inner core baffles 409.

The outer casing 408 and the inner core baffle 409 of the retractable baffle 401 are supported by respective lever arms 410. The respective lever arms 410 pivot independently on the bearing support 404, i.e., pivot at the same pivot point. The distal end of the lever arm 410 for supporting the outer casing 408 is further movably supported by the guiding support portion 403, wherein the upper distal end is operatively moved along the guiding support portion 403. The guide support portion 403 is provided with a guide rail to allow the lever arm 410 to rotate about the pivot point and move along the guide rail. The telescoping flap 401 retracts inwardly or outwardly on the same single shaft. When the telescoping flap 401 is retracted inwardly, the inner core baffle 409 is simultaneously retracted within the outer casing 408.

One end of a lever member 406 is coupled to the outer casing 408 lever arm 410 and the other end is coupled to the telescoping baffle lever joint 405. The other lever member 406 has one end connected to the lever arm 410 of the inner core baffle 409 at a close distance to the bearing support portion 404 and the other end to the telescopic baffle lever joint 405. The length of the lever member 406 of the lever arm 410 coupled to the inner core baffle 409 is longer than the lever member 406 of the lever arm 410 coupled to the outer casing 408. This allows the inner core baffle 409 to be driven outward at a faster rate or retracted inward. Since the inner core baffle 409 moves at a faster speed than the outer casing 408, the inner core baffle 409 will simultaneously extend outwardly or inwardly with the outer casing 408.

The telescoping baffle lever joint 405 is generally an L-shaped connector that is coupled to the motor assembly 402 at a curved corner thereof. The distal end of the telescoping baffle lever joint 405 is pivotally coupled to the two lever bars 406, as described above. Since The other end of the telescoping baffle lever joint 405 that extends outwardly from the curved corner serves as a stop arm that limits the rotation of the telescoping baffle lever joint 405.

Similar to the baffle lever joint 105 shown in FIG. 1, the motor assembly 402 drives the telescoping baffle lever joint 405 to operatively follow the curved corner in a clockwise, counterclockwise direction. Rotate. Since the lever lever member 406 is commonly pivotally coupled to the distal end of the telescoping shutter lever joint 405, the telescoping shutter lever joint 405 simultaneously drives the lever lever member 406 on a single shaft and cannot be moved in other manners or directions. Since the retractable flap 401 is prevented from pivoting in other directions than when the telescoping baffle lever joint 405 is being driven, the safety features of the barrier 400 can be further improved.

Motor assembly 402 in accordance with another embodiment of the present invention includes an integrated control unit. Motor assembly 402 includes an electric motor and a gear assembly that angularly drives telescoping baffle lever joint 405.

The integrated control unit of the motor assembly 402 is different from the integrated control unit of the motor assembly 101 shown in FIG. 1 because of the greater force required to drive the telescoping baffle lever joint 405. The reason for the greater force is that the inner core baffle 409 of the retractable baffle 401 must be driven outward at a faster rate than the outer casing 408. The integrated control unit in the motor assembly 402 controls the force required to drive the telescoping baffle lever joint 405.

The gear assembly of motor assembly 402 includes a satellite gear and a helical gear. The configuration and description of the gear assembly is similar to the gear assembly of the motor assembly 101 of FIG. Similarly, the telescoping baffle lever joint 405 is erected to the gear assembly.

Similar to Fig. 1, the metal bottom frame 407 supports the member including the barrier 400, and the bottom of the metal bottom frame 407 is fixed to the ground to provide a stable foundation for the barrier 400. The bearing support portion 404 is mounted on the metal bottom frame 407.

The guide support portion 403 is mounted in the middle of the upper end of the metal base frame 407 with respect to one of the distal ends of the bearing support portion 404 to force the lever arm 410 of the support housing 408 to move along the guide rail. The bearing support portion 404 is mounted on one of the corners of the bottom of the metal bottom frame 407. A lever member 406 is coupled to the middle of the lever arm 410 of the housing 408. At a close distance from the bearing support 404, another lever member 406 is coupled to the lever arm 410 of the inner core baffle 409. The telescoping baffle lever joint 405 is erected to the gear assembly of the motor assembly 402. Unlike the motor assembly 101 in the barrier 100 of Figure 1, the motor assembly 402 is erected to the intermediate portion of the metal bottom frame 407, on the bottom and having a distal length therewith.

When the telescoping flapper 401, the telescoping baffle lever joint 405 and the lever lever member 406 are collectively mounted on the metal bottom frame 407 to form a configuration similar to that of a four-bar linkage. The configuration of each member will be described below in conjunction with Figures 6A-6C.

Figure 5 shows a perspective view of the barrier 400 of Figure 4, including a retractable baffle 401 in an open position. The outer casing 408 and the inner core baffle 409 are retracted inwardly by the motor assembly 402. The position of each member in the barrier 400 allows the entire structure including the retractable shutter 401 to be fixed in a housing (not shown).

Fig. 6A shows the structure of the barrier 400 of Fig. 4. Barrier 400 The structure is generally a four-bar linkage 600 for controlling the outer casing 408 and the inner core baffle 409 under a telescoping action. Figure 6B is a diagrammatic view of the four bar linkage when the barrier 400 is in its open position. Figure 6C is a diagrammatic view of the four-bar linkage when the barrier 400 is in its closed position.

The four-bar linkage 600 includes a bottom rod 601, a primary rod 602, a casing secondary rod 603, an inner core baffle secondary rod 604, a casing tertiary rod 605, and an inner core Body baffle tertiary rod 606.

The telescoping baffle lever joint 405 acts as a primary rod 602 for the four-bar linkage 600. The lever members 406 connected to the corresponding outer casing 408 and the inner core baffle 409 serve as the outer casing secondary rod member 603 and the inner core baffle secondary rod member 604, respectively. The lever arm 410 of the outer casing 408 acts as the outer casing tertiary rod 605, while the lever arm 410 of the inner core baffle 409 acts as the inner core baffle tertiary rod 606. The bottom bar 601 includes two fixed points, and the outer casing three-stage bar 605 and the inner core baffle three-stage bar 606 pivot about a first fixed point 612 of the bottom bar 601. The primary rod 602 rotates about a second fixed point 613 of the bottom rod 601.

The primary rod 602 is configured to simultaneously swing the outer shell tertiary rod 605 and the inner core baffle tertiary rod member 606 through the outer casing secondary rod member 603 and the inner core baffle secondary rod member 604, respectively. . A stop 607 is mounted on the metal bottom frame 407 to restrict the primary rod 602 from rotating freely about the gear assembly of the motor assembly 402. In particular, the primary rod 602 is limited to rotate over a limited stroke length. The stroke length of the primary lever 602 is preset in accordance with the length of one stroke required for a retractable shutter 401.

One side of the primary rod 602 also has a spring connector 609 attached to its end. Spring connector 609 allows for elastic components in barrier 400 One end is attached to it. The other end of the resilient member can be coupled to another spring connector 609 that is mounted on the bottom of the metal bottom frame 407.

One end of the outer casing secondary member 603 and one end of the inner core baffle secondary rod member 604 are erected to the longer side of the primary rod member 602. The primary rod 602 is sandwiched between the outer casing secondary rod 603 and the inner core baffle secondary rod 604. The other end of the outer casing secondary rod 603 is erected to the middle of the outer casing tertiary rod 605. The other end of the inner core baffle secondary rod 604 is coupled to the wider end of the inner core baffle tertiary rod 606 proximate the bearing support 404.

The outer casing tertiary rod 605 supports the outer casing 408 of the telescoping baffle 401. One end (wider end) pivots about the bearing support 404. The other end of the outer casing tertiary rod 605 is coupled to the guide support 403, and when the four-bar linkage 600 is operable, the outer casing tertiary rod 605 moves along the guide support 403, thus when the barrier 400 is opened or closed In position, the outer casing 408 of the retractable flapper 401 is guided to move in both directions.

Similarly, the inner core baffle tertiary bar 606 supports the inner core baffle 409 of the telescoping baffle 401 with its wider end pivoted about the bearing support 404. The inner core baffle tertiary rod 606 has the same pivot point as the outer casing tertiary rod 605.

The inner core baffle secondary rod 604 is erected to the inner core baffle tertiary rod 606 at a distance from the bearing support 404. The length of the bearing support portion 404 is longer than the outer casing member 603 because the speed required for the inner core baffle 409 of the retractable baffle 401 to retract inwardly or outwardly must be based on the retractable The stroke length of the plate 401 is differentially moved. The speed of the retractable flap 401 is preferably higher than the outer shell of the retractable flap 401 The speed required for 408 is fast. This allows the inner core baffle 409 and the outer casing 408 to be retracted and extended simultaneously and serves as a barrier for the barrier 400.

The four-bar linkage 600 is similar to the four-bar linkage 300 of Figure 3, but includes two configurations of crank-rocker linkages. The first crank-rocker type linkage set includes a bottom rod 601, a primary rod member 602, a casing secondary rod member 603, and a casing tertiary rod member 605. The second crank-rocker type link set includes a bottom rod 601, a primary rod member 602, an inner core baffle secondary rod member 604, and an inner core baffle tertiary rod member 606. Similarly, the length of the primary member 602 is the shortest, and the outer casing third member 605 and the inner core baffle tertiary member 606 are rocked at a curved curvature 610. It is known in the art to vary the length and connection points of different configurations of the rods to control the movement of the four-bar linkage 600.

Referring to FIG. 6B, each end of the bottom rod 601 is marked with a circle to show the first fixed point 612 and the second fixed point 613 of the bottom rod 601. The bottom bar 601 is the only one of the four-bar linkages 600 that is maintained in its rest position and pivots in any direction.

The length of the primary rod 602 is the shortest among the four rod sets 600. One side of the primary rod 602 is erected at one point A with one end of the outer casing secondary rod 603 and the inner core baffle secondary rod 604. A spring connector 609 on the primary lever 602 allows one end of the resilient member 411 to be coupled. The other end of the elastic member 411 is connectable to another spring connector that is erected to the metal bottom frame 407. The primary rod 602 rotates along a same axis along a small curved curvature 611.

The other end of the outer casing rod 603 is erected at point B to the outer casing tertiary rod 605 (actually the erection to the outer casing 408 supporting the 6A diagram) One end of the telescopic baffle lever joint 405) at the center of the lever arm 410. The other end of the inner core baffle secondary rod 604 is erected at point C to the inner core baffle tertiary rod 606 (which is actually a lever arm that is erected to the inner core baffle 409 supporting Figure 6A) Telescopic baffle lever joint 405 of 410. The outline of the inner core baffle secondary rod 604 is longer than the outer casing secondary rod 603.

The other end of the outer casing tertiary rod 605 and the inner core baffle tertiary rod 606 is erected to one end of the bottom rod 601 (more specifically, the bearing support portion 404). The length of the outline of the inner core baffle tertiary rod 606 is shorter than the length of the outer casing tertiary rod 605.

The outline of the inner core baffle secondary rod 604 is longer because the inner core baffle 409 is retracted inwardly or outwardly at a faster rate than the outer casing 408 requires. In addition, the inner core baffle secondary rod member 604 is erected to have a close distance from the bearing support portion 404 and, therefore, is shorter in length of the outline of the inner core baffle tertiary rod member 606.

Point A rotates along a small curved arc 611 as the barrier 400 moves from its open position to its closed position, or from its closed position to its open position. Similarly, point B and point C are simultaneously rotated by curved curvature 610.

Referring to Figure 6C, the retractable baffle 401 extends outwardly when the barrier 400 is in its closed position. The primary rod member 601 passes through the outer casing secondary rod member 603 and the inner core baffle secondary rod member 604 to simultaneously drive the outer casing tertiary rod member 605 and the inner core baffle tertiary rod member 606. Point A is rotated along a small curved curvature 611 to a point D. Point B and point C follow curved curvature 610 to point E and point F, respectively. Similarly, the first fixed point 612 and the second fixed point 613 of the bottom bar 601 are maintained at the same rest position as shown in FIG. 6B.

A four-bar linkage set for illustration is disclosed in the above embodiment. According to the invention, the four-bar linkage can be replaced by any mechanical linkage or multi-bar linkage system. Through the mechanical linkage or multi-bar linkage system, the stroke, speed and acceleration of the baffles can be easily controlled, altered, and improved by a slight modification of the multi-rod linkage or mechanical linkage.
