Description

Description Entrance Device Having Barrier Arm Unlocking Means Field of Invention This invention relates generally to an improved gated entrance device permitting passage in one direction and specifically relates to an entrance device having barrier arm unlocking means. This invention further relates to a gated entrance device having a gate collapsing means for allowing unobstructed traversal of said gated entrance device in either direction in case of an emergency. This invention further relates to a method of traversing a gated entrance device.

Background of Invention This invention relates to the art of self-closing gates or barriers that permit passage in one direction, but not in the other direction.

For example U.S. Patent No. 5,615,520 granted to John D. McGuire provides for a one-way gate for allowing passage in one direction whose internal mechanical works are concealed within an enclosure, those mechanical works including independent means to perform three function of, first, biasing the gate to return to a closed position; second, limiting the range of motion of the gate between a closed position and a fully open stop;
and third, providing a damper to retard the motion of the gate.

Some prior art self-closing gates or barriers permit a person to gain passage through said one-way gate in a direction opposite to said one direction by displacing said gate or barrier said one direction and passing through the resulting unobstructed passageway. There is a need therefore for entrance devices which prevent the one-way gate or barrier from being "tampered" in this way. For example, WO 93/23799 provides for at least one entrance gate, and a system for controlling entrance through said entrance gates comprising, first, entrance passageway defined by posts on which gates are pivotally mounted; second, a sonar sensor means which functions to detect the presence of people and objects in the vicinity of the passageway and to deliver signals to a control means for controlling opening and closing of the gate; wherein said sonar sensor means includes at least one sonar which is mounted in or in the vicinity of the passageway.
The prior art entrance device utilizing sonar is complicated in that said entrance device requires, first, a sonar emitting device; second, an electronic unit for amplifying sonar pulses; third, a microprocessor for sampling said sonar signals; fourth, a microprogram operably associated with said microprocessor for processing said sonar signals to a further microprocessor which controls opening and closing of the gates.
Operation of said prior art entrance device utilizing sonar also requires configuration of said microprocessors to store input related to a defined external measuring area within which objects are detected by said sonar sensing means.

There is a need therefore for an entrance device of simple construction that is easy and inexpensive to produce, that can be installed without difficulty, and which is easy to operate.

Summary of the Invention In accordance with a first aspect of the invention, an entrance device is provided having at least two barrier means to permit entrance in one direction comprising, a first barrier means manually displaceable from a closed position to an open position; and second barrier means manually displaceable from a closed position to an open position when said first barrier means is being engaged to achieve said second open position;
wherein said first and second barrier means are presented by said entrance device in sequence.

In another aspect of this invention, an entrance device to permit entrance in one direction is provided, said entrance device comprising: (a) at least one partition member defining a passageway; (b) first barrier arm assembly mounted on said partition member, said first barrier arm assembly comprising, (i) a first barrier arm, and (ii) first barrier arm rotor means connected to said first barrier arm and rotatably mounted on said partition member and adapted for manual rotation of said first barrier arm between a first closed position and second open position; and (c) second barrier arm assembly mounted on said partition member and spaced apart from said first barrier arm assembly, said second barrier assembly comprising, (i) a second barrier arm; (ii) second barrier arm rotor means connected to said second barrier arm and rotatably mounted on said partition member and adapted for manual rotation of said second barrier arm between a first closed position and second open position; and (iii) sequential barrier arm rotor releasing means comprising, (A) a stopping means comprising, a stopping member presented by said partition member adjacent to said second barrier arm rotor means; and stopping arm presented by said second barrier arm rotor means and operably associated with said stopping member, wherein said stopping means prevents rotation of said second barrier arm rotor means from said closed position toward said open position; and (B) releasing means for displacing said stopping member, thereby releasing said stopping means when said first barrier arm rotor means is rotated from said closed position toward said open position, and thereby allowing rotation of said second barrier arm rotor means from said closed position toward said open position.

In a further aspect of the invention, one may additionally find a collapsing means for manually displacing said first and second barrier arms from said first closed position or second open position to achieve a third collapsed position wherein said first and second barrier arms permit unobstructed passage through said passageway.

In a still further aspect of the invention, a method of traversing an entrance device having at least a first and second manually operable barrier means mounted in sequence on at least one partition member comprising the steps of: (a) manually displacing said first barrier arm so as to allow passage past said first barrier arm; (b) said first barrier arm releasing a blocking means that prevents displacement of said second barrier arm, so as to allow passage past said second barrier arm by having displaced said first barrier arm; and (c) manually displacing said second barrier arm so as to exit said entrance device.

It is yet another aspect to provide an entrance device having at least two barrier means to permit entrance in one direction comprising: a first barrier means manually displaceable from a closed position to an open position; and second barrier means manually displaceable from a closed position to an open position when said first barrier means is being engaged to achieve said second open position; sequential barrier releasing means for opening said first and second barrier means in sequence; and sequential barrier releasing means including releasing means for releasing at least one of said barrier arms for manual displacement from a closed position to an open position.

In the drawings, preferred embodiments of the invention are illustrated by way of example. It is expressly understood that the description and the drawings are only for the purpose of illustration and as an aid to understanding and are not intended as a definition of the limits of the invention.

Best Mode for Carrying Out The Invention In the description which follows, like parts are marked through the specification and the drawings with the same respective reference numerals. The drawings are not necessarily to scale, and in some instances proportions may have been exaggerated in order to more clearly depict certain features of the invention.

Referring to Figure 1, there is illustrated a first preferred embodiment of the entrance device 10 in which there are three pairs of barrier arms. In this first preferred embodiment of the invention, the entrance device comprises a first partition member 12 and second partition member 14. Each of said first and second partition members 12, 14 further comprises a top member 16 and pair of support posts 18 for supporting each of said top members 16. Each of said first and second partition members 12, 14 further comprise a first barrier arm 20, second barrier arm 22 and third barrier arm 24 which are mounted on said top members 16, in a manner made evident below.
Each of said top members 16 includes a casing 26 for enclosing the mechanism as shown in the drawings corresponding to each of said first, second and third barrier arms 20, 22, 24 and described in detail below.

Each of said supporting posts 18 further comprises a base 28 for fixing each of said partition members 12, 14 to the floor or ground by means of an attachment means, for example, a flange 17 associated with said supporting posts 18, which flange presents holes for receiving screws which are secured into the ground or floor.
Partition members 12, 14 are fixed to the floor or ground spaced apart from each other so as to delimit or define a passageway, as shown in Figure 1.

It should be understood that while a pair of supporting posts 18 are illustrated herein as means for supporting top member 16, this invention also contemplates alternate means for supporting top member 16, such as one support post for supporting each of said top members 16, attaching said top member 16 to a support wall extending all or substantially all the length of top member 16, or attaching said top member 16 to an existing barrier such as a wall, using an attachment means such as screws or the like.

Each of said first and second partition members 12, 14 present the same mechanical structure when casing 26 is removed, as best illustrated by Figure 2, which presents a top view of top member 16 of each of said first and second partition members 12, 14 with casing 26 removed.

Now referring to Figure 3, the various structural elements of each of said first and second partition members 12, 14 are illustrated. More specifically Figure 3 shows the complete third barrier arm assembly 36 including the rotor post reinforcing bracket 43, while the second barrier arm assembly 34 has the rotor post reinforcing bracket 43 removed, and the first rotor arm assembly 32 drawn with phantom lines to better illustrate the first rotor post 37. Top member 16 presents main base plate 30, first barrier arm assembly 32, second barrier assembly 34 and third barrier arm assembly 36.
Main base plate 30 presents first, second and third rotor posts 37, 38 and 39.
Now referring to Figure 4, the structure of said first barrier arm assembly 32 is represented, which structure is also representative of said second and third barrier arm assemblies 34, 36, and also of the arm assemblies which are part of the various embodiments of the invention described below. Figs. 4 and 7 show rotor post reinforcing bracket 43 in partial cut away view.

Said first barrier arm assembly 32 comprises said first barrier arm 20 which is connected to a rotor bottom plate 42 (see Figure 9a) spaced from a rotor top plate 48 (see Figure 7). A rotor bearing tube 44 is disposed between the rotor bottom plate 42 and rotor top plate 48 and receives and rotationally engages rotor bearing 46.
Said rotor bottom plate 42 and rotor bearing 46 are received by said rotor post 37 thereby permitting manual rotation of barrier arm 20 about said rotor post 37. The first, second and third barrier arm assemblies 32, 34 and 36 also present side covers 31, 33 and 35.

As best shown in Figure 3, each of said first, second and third barrier arm assemblies 32, 34, 36 further includes a rotor post reinforcing bracket 43 which is placed on top of barrier arm assemblies 32, 34, 36 so as to prevent them from being removed from said rotor posts 37, 38, 39 while permitting rotatable displacement of said rotor bottom plate 42 (as shown in Figure 3). Said main base plate 30 further presents main support tube 49. Main support tube 49 presents fastening holes 50a, 50b which communicate with corresponding holes presented by said rotor post reinforcing bracket 43, whereby said rotor post reinforcing bracket 43 is secured to said main support tube 49 using fastening means such as nuts and bolts, or the like. The rotor post reinforcing bracket 43 reinforces the rotor post in that it restricts deflection of the barrier arm assemblies 32, 34 and 36 when for example some one hangs from the barrier arms 20, 22 and 24.

In accordance with the above, said first barrier arm assembly 32 permits manual displacement of said first barrier arm 20 from a first closed position to a second open position. Referring to first barrier assembly 32, as illustrated in Figure 5, barrier arm 20 is shown in said first closed position. Now referring to first barrier arm assembly 32, as illustrated in Figure 6, barrier arm 20 is shown in said second open position.
Now referring to Figure 5, one provides means for resisting or inhibiting movement of said barrier arm 20 in a direction other than said one direction (said one direction being direction "A") when said barrier arm 20 is in said closed position. In the embodiments of the present invention described herein, said means for inhibiting movement is presented by a base plate stop 52 which is presented by said main base plate 30, and further by rotor stop block 54 which is presented by rotor bottom plate 42. As best shown in Figure 5, said base plate stop 52 comes into contact with rotor stop block 54 when an attempt is made to rotate said barrier arm 20 in a direction opposite to said direction A (direction B) when said barrier arm 20 is in said first closed position.
As illustrated in Figure 7, the various embodiments of the invention described herein also provide for a biasing means 41 for said barrier arms 20, 22, 24 to be biased toward said first closed position. Said biasing means 41 prevents passage through said entrance device 10 in said direction B by ensuring that once a person has passed through said entrance device in direction A, said barrier arms 20, 22, 24 return to said closed position to obstruct passage through said entrance device 10. In the embodiments of the invention described herein, said biasing means 41 is presented by a rotor return spring 56 which is preferably operably associated with each of said barrier arm assemblies 32, 34, 36. Said rotor return spring 56 is mounted between a spring pin 58 presented by said rotor top plate 48, and spring post 60 presented by said main support tube 49.

In order to prevent said barrier arm assemblies 32, 34, 36 to return from said second open position to said first open position with great force in combination with said rotor return spring 56, and thereby possibly causing injury to person traversing said entrance device 10 soon after another person, it is desirable to associate some form of dampening means with said barrier arm assemblies 32, 34, 36. As best shown in Figure 7, in the embodiments of the invention described herein, said dampening means is presented by a dampening cylinder 62 which is also operably associated preferably with each of said barrier arm assemblies 32, 34, 36. Said dampening cylinder 62 is mounted to said main support tube 49 and operably connected with said rotor top plate 48, again as illustrated in Figure 7.
Figure 8 illustrates said entrance device 10 in operation by reference to the first embodiment of the invention disclosed herein, and shows the passage of a person between said first and second partition members 12, 14. The entrance device 10 described herein restricts passage therethrough into passage in said one direction only by means of a sequential releasing means. Said sequential releasing means presents means for permitting displacement of second barrier arm 22 only once said first barrier arm 20 has been previously displaced; and of the third barrier arm 24, in turn, only once said second barrier arm 22 has been previously displaced.

As particularized below, said sequential releasing means can either be provided mechanically or electronically.

Again in reference to Figure 7, said sequential releasing means is illustrated which more particularly operates as follows. When said first barrier arm 20 is displaced, said second barrier arm 22 is thereby mechanically released by way of said sequential releasing means, so long as said first barrier arm 20 has not yet returned to said first closed position. Similarly, manual displacement of said second barrier arm 22 in turn releases said third barrier arm 24 thereby permitting said third barrier arm 24 to be opened, but only so long as said second barrier arm 22 has not yet returned to said first closed position.

The biasing means 41 and dampening cylinder 62 may be adjusted in a manner well-known to those skilled in the art, in order to provide for return of said first and second barrier arms 20, 22 to said first closed position more slowly than it would take such person to make its way from one barrier arm to the next barrier arm so as to minimize the chance of the first and second barrier arm 20, 22 returning to the first closed position too quickly and before the next barrier arm can be manually displaced.
Moreover, the length of the arms 20, 22 and 24 tend to contact a user and then swing to the closed position once the user has passed through the appropriate position.
Now referring to Figure 9a, a preferred embodiment of a first mechanical sequential releasing means 64 is illustrated, which in this figure is operably associated with said first and second barrier arm assemblies 32, 34. Said first sequential releasing means 64 comprises a rotor release rod 66, pivot cam arm 68, pivot bushing 70, and pivot stop bar 72.

Said rotor release rod 66 is pivotally or rotatably connected to said first rotor bottom plate 42a by means of rotor release stud 74 presented by the top of said first rotor bottom plate 42a and rotor bushing 76. Connected to said rotor release rod 66 at the end of said rotor release rod 66 opposite to said rotor release stud bushing 76 is a rotor release block 78.

Said main base plate 30 further presents a pivot assembly post 80. Said pivot cam arm 68 and pivot stop bar 72 are rotatably mounted on said pivot assembly post 80 by means of said pivot bushing 70, whereby said pivot stop bar 72 can be rotated from a first blocking position in which said pivot stop bar 72 blocks said rotor stop block 54, thereby preventing rotation of said second barrier arm 22 from said first closed position to said second open position; to a second releasing position wherein said rotor stop block 54 is released thereby permitting manual displacement of said second rotor bottom plate 42b.

In operation, as best shown in Figure 9b, when said first barrier arm 20 is manually displaced, said rotor bottom plate 42a is rotated, and thereby said rotor release rod 66 is displaced atop said main base plate 30 toward said first barrier arm assembly 32. Said displacement of said rotor release rod 66 causes said rotor release block 78 to displace said pivot cam arm 68 thereby causing pivot stop bar 72 to rotate away from said second rotor bottom plate 42b. Rotor stop block 54 is consequently released, thereby permitting said second barrier arm 22 to be manually displaced from said first closed position to said second open position.

A pivot assembly return spring 71 biases said pivot stop bar 72 toward said first blocking position. Consequently, when said first rotor bottom plate 42a returns to said first closed position by means of said rotor return spring 56 and dampening means 62, said pivot stop bar 72 again blocks said rotor stop block 54, thereby preventing rotation of said second rotor bottom plate 42b from said first closed position to said second open position.
Said third barrier arm assembly presents a second releasing means 77 identical to said first sequential releasing means 64 for releasing said third barrier arm 24 when said second barrier arm 22 is manually displaced, as best shown in Figure 9c, 9d.
Also as best shown in Figure 9a, said first barrier arm assembly 32 may also be provided with a first rotor blocking means 79 for preventing said first rotor bottom plate 42a from being rotated from said first closed position to said first open position. Said first rotor blocking means 79 is presented by a first barrier stop bar 81 which is mounted on said main base plate 30 by means of a first barrier post 82, along with first barrier bushing 84 to provide for rotatable displacement of said first barrier stop bar 81 from a first blocking position in which said first barrier stop bar 81 blocks said rotor stop block 54, thereby preventing rotation of said first barrier arm 20 from said first closed position to said second open position; to a second releasing position wherein said rotor stop block 54 is released thereby permitting manual displacement of said first rotor bottom plate 42a.
Further associated with said first barrier stop bar 81 is a rotating arm 85.
Said rotatable displacement of said first barrier stop bar 81 can be obtained by providing various means for engaging said rotating arm 85, such as a turn-key release, or solenoid combined with an access card reader or remote activation, connection to fire alarm systems, proximity sensors or similar devices.
In a second preferred embodiment of the entrance device described herein, each of said first and second partition members comprises two barrier arm assemblies 32, 34 comprising the constituent elements described above, as shown in Figure 10.

In a third preferred embodiment of the entrance device described herein, said entrance device comprises only one partition member having two barrier arm assemblies 32, 34 wherein a passageway is defined by said partition member, and an external barrier such as a wall or barrier, or handrail mounted on a wall, as shown in Figure 11.

In a fourth preferred embodiment of the entrance device described herein, said entrance device also comprises only one partition member, but said partition member presents three barrier arm assemblies, as illustrated in Figure 12.
In a fifth preferred embodiment of the entrance device described herein, said entrance device is provided with barrier arm configurations of either of said first, second, third or fourth embodiments of the invention described herein, and an electronic sequential releasing means rather than the mechanical sequential releasing means described above. Said electronic sequential releasing means consists of a solenoid operably associated with said second barrier stop bar 72, and sensing means for sensing when said first barrier arm is displaced from said first closed position to achieve said second open position, wherein said sensor is activated when said first barrier arm 20 is displaced from said first closed position to achieve said second position so as to engage said pivot stop bar 72 thereby permitting manual displacement of said second rotor bottom plate 42b, as described above. Said sensing means may be provided, for example, by a photo electric beam. Any subsequent barrier arm assemblies, if any, are similarly provided with a sensing means and solenoid.

In a modification to the fifth preferred embodiment sensing means such as a photo electric beam or the like could be placed in advance of any barrier arm 20, 22, 24 to indicate the presence of a person attempting to traverse the entrance device in the desired direction "A", whereupon the signal from the beam would activate the solenoid operably associated with the barrier arm to which the person is attempting to traverse.
In a sixth preferred embodiment of the invention described herein, said entrance device is further provided with a collapsing means for displacing said barrier arms 20, 22, 24 presented by either of said first, second, third or fourth preferred embodiments of the invention described above, from said first closed position or second open position to achieve a third collapsed position wherein said barrier arms permit unobstructed passage through said passageway. Figure 13 illustrates the collapsed position.
The entrance device could be collapsed in the event of an emergency so as to prevent unobstructed passage through the device in both directions in the event of a fire or the like.
As best shown in Figure 14, the preferred embodiment of said collapsing means is provided by a hinge means 86, displaceable locking means 88, wherein said hinge means 86 is presented by a pivot shaft 87 around which said top member 16 may be pivoted.

In the preferred embodiment of said collapsing means described herein, said hinge means 86 is presented by each of said support posts 18, however said hinge means 86 could be easily adapted to be presented by a single support post or alternate means for supporting top member 16 such as a support wall by fixing said hinge means 86 to the top of such a support wall using a flange and screws, for example.

As illustrated in Figure 15, said top member 16 and support posts 18 present said displaceable locking means 88 by providing a collapsing ramp 92 secured to post 18.
The collapsing ramp 92 communicates with bottom opening 95 of said main base plate 30. Said collapsing ramp 92 comprises a ramp edge 94 and locking notch 96.
Said top member 16 provides a break away roller 98 which is biased to engage said locking notch 96 and thereby hold said hinge means 86 in place.

Now referring to Figure 16a, the structure providing said displaceable locking means 88 comprises a roller frame 97a and 97b corresponding to each of said collapsing ramps 92 presented by said entrance device 10, depending on the means used to support said top member 16, as provided above. As best shown in Figure 15, said roller frame 97a and 97b each define an opening 99 for receiving a shaft about which break away roller 98 rotates within said roller frame 97a and 97b.

Again referring to Figure 16a, each of said roller frames 97a and 97b are interconnected by means of a pair of rods 100, 102. Top member 16 is also provided with a collapsing means release handle 104 which is connected to the adjacent roller frame 97a and 97b for engaging said rods 100, 102 to consequently displace said roller frames 97, using for example a hinged handle in combination with a clevis 101 for displacing said rods 100, 102.
Top member 16 also provides two spring mechanisms 1.06 opposite to said collapsing means release handle 104 corresponding to each of said pair of rods 100, 102.
Said spring mechanisms 106 present means for biasing said roller frames 97, and consequently said break away rollers 98, toward said breakaway ramp 92.

Referring to Figs. 15 and 14a, said barrier arms obstruct traversal through said passageway as said break away roller 98 engage said locking notch 96, thereby preventing said top member 16 from being pivoted to achieve said collapsed position.

As best shown in Figure 16b, in operation, when said collapsing means release handle 104 is engaged, said rods 100, 102 cause said roller frames 97a and 97b to be displaced, thereby removing said break away rollers 98 from said locking notches 96, thereby permitting top member 16 from being pivoted about hinge means 86 to achieved said collapsed position. The roller frames 97a and 97b generally move in unison with one another to remove the break away rollers 98 from the locking notches 96.
However, the frames 97a and 97b can move independently of one another since rod 102 is welded to frame 97b but traverses through frame 97a (frame 97a has two holes permitting rod 102 to move freely of frame 97a). In other words, by pulling handle 104 then 97b is moved by rod 100 while frame 97a is moved by rod 100; but a self adjustment means (i.e. locking nuts 103) are provided to allow adjustment so that both frame 97a and 97b move appropriately in unison.

In order to return top member 16 to said first position wherein said barrier arms 20, 22, 24 obstruct traversal through said passageway, said top member 16 is pivoted in direction C, as shown in Figure 17. As said break away rollers 98 are biased toward said collapsing ramp 92, said break away rollers 98 travel up ramp edge 94 to locate said locking notches 96 when said top member 16 has been pivoted in direction C so as to permit communication between said locking notches 96 and break away rollers 98, thereby locking said top member 16 in place, as described above.

Other means can be provided to permit the barrier arm to swing out of operable position in the event of an emergency. For example, the barrier arms 20, 22 and 24 may be releasably secured to the upper and lower rotor plates 48 and 42 for rotation as described. In the event of an emergency the handle 104 could be pulled so as to release the arms 20, 22 and 24 for free pivotal movement with respect to the plates 42 and 48.
In other words, the arms 20, 22 and 24 could freely horizontally swing in either direction A or B by manually pushing same. In this case, the handle 104 would release a pin so as to disengage the arms 20, 22 and 24 from plates 42 and 48.

An advantage of the present invention over turnstile-type entrance devices is that the entrance device disclosed herein can be negotiated by persons using a wheelchair, in which case said barrier arms are generally displaced by the shoulders of a person of average height, or by a person pushing a shopping cart or stroller. Separate entrances are required in these circumstances where an ordinary turnstile-type entrance is used.
Furthermore, the device may also be used in airports where individuals usually hold luggage in their arms. By utilizing the device herein there would be no need to lift the luggage over the device but rather to just walk through with the luggage dangling from the arms.

While the preferred embodiments of the invention described herein refer to use of barrier arms as means of obstructing passage through said passageway, it should also be understood that alternate means for obstructing passage through said entrance devices could be used such as a series of U-shaped gate assemblies, paddles or the like.

Also, the preferred embodiments of the invention described herein, provide for each of said partition member to have two or three barrier arms. However, it is also possible to provide for four, five or more barrier arms if need be.

Also, in order to achieve the benefits of the invention, said barrier arms should be spaced apart along said partition members at a distance that is sufficient to make it difficult for a person seeking entrance through said entrance device in said direction B
by displacing the first barrier arm, and then subsequent barrier arms sequentially to gain passage through said last pair of barrier arms.

Said top member can be further provided with a detecting means operably associated with at least one of said barrier arms for sensing when said barrier arms are displaced from said first closed position to said second open position, and providing signals to a microprocessor for generating data related to the traffic passing through said entrance device, or to a security monitor or camera or other device which monitors traffic activity. As shown in Figure 18, said detecting means may be provided, for example, by an ordinary solenoid switch 110, having a solenoid connection arm 112. Said solenoid switch 110 is operably associated with said rotor bottom plate 42. Said solenoid switch comprises a spring means (not shown) which biases said solenoid connection arm toward said rotor bottom plate 42. Said solenoid switch is easily adjusted to provide an electronic signal when said rotor bottom plate 42 is rotated, as described above, thereby engaging said solenoid connection arm 112. A counting means can then be operably associated with said detecting means for tracking traffic flowing through said entrance device.

It will be understood from the above description, that if a person attempts to traverse the preferred embodiments of said entrance device presenting said mechanical sequential releasing means and it takes more time than was anticipated for such person to traverse said embodiment of the entrance device when adjusting said biasing means and dampening cylinder, then it is possible that such person may be trapped between two sets of barrier means, if the previous barrier means has returned to said first closed position before the next barrier means is manually displaced. While it would be relatively simple to displace the previous barrier means to release the next barrier means, some persons traversing said entrance device may not realize this fact, or perhaps may not be able to do so due to physical impediment, for example. To address this eventuality, said entrance device may be easily equipped with an alarm means comprising, for example, a timer in combination with a solenoid switch which provide an alarm signal if a person has traversed, for example, said first barrier means, and a certain period of time has elapsed and said second barrier means has not yet been manually displaced.
Said alarm signal could result in a siren being sounded, for example, either in the immediate vicinity of said entrance device or at an administrative office, for example.

The working components of said entrance device are readily available and can be assembled in a manner well-known to those skilled in the art. Said main base plate 30, support posts and casing 26 may be fashioned from sheet metal, but may also comprise some other rigid material such as a rigid plastic polymer or wood.
Further Alternate Embodiments Further alternate embodiments of the invention are illustrated in Figures 19 -inclusive.

Like parts are marked through the specification and the drawings with the same respective reference numerals. Accordingly, Figures 19 and 20 are similar to those shown in Figure 1 and 13 and illustrate an entrance device 10 having first partition member 12 and second partition member 14, each of which comprises a top member 16, a pair of support posts 18 for supporting each of the top member 16 and first barrier arm 20, second barrier arm 22, and third barrier arm 24.

Figure 20 illustrates the entrance device 10 in a collapsed position and is different from that shown in Figure 13 in that the casing 26 is substantially located between the pair of support posts 18 in both of the positions shown in Figures 19 and 20 while Figure 13 shows that the casing 26 protrudes into the passageway in the collapsed position. In other words the clearance or distance between the partition members 12 and 14 in the collapsed position shown in Figure 20 is greater than that shown in Figure 13.
The entrance device 10 illustrated in Figures 19 - 28 inclusive operates in a fashion as described above except as described below.

More specifically, Figure 21 illustrates a cross-sectional view of one of the support posts 18 which has an outer post frame 219 and inner post frame 220 which are each comprised of stainless steel plate or the like. The top member 16 presents at each end thereof an end plate 214 fixedly secured to the top member 16 by means of welding or the like. At least one of the end plates 214 has secured thereto a top member pivot assembly 216 which permits rotation of the top member 16 relative the support post 18.
The top member pivot assembly 216 includes a threaded pin or shaft welded to the inner post frame 220 and a sleeve or bushing 221 welded to the end plate 214 as illustrated.
A locking nut 223 secures the parts together for relative rotation. As shown in Figure 21 the thickness of inner post frame 220 is greater than outer post frame 219, although this does not need to be the case provided that the frame 220 exhibits sufficient strength characteristics.

Figure 21 also illustrates the position of the top member 16 for normal operation in a non-collapsed mode or position through the use of a top member locking pin 212.
Locking pin 212 is displaceable within the locking pin bushing 213. Locking pin bushing 213 is secured to the inner post frame 220 by means of welding or the like.
The locking pin 212 securely fixes the post and top member 16 together when locking pin 212 is received by locking pin tapered hole 215.

The top member 16 may be moved to the collapsed position shown in Figure 20 by placing one's hands or fingers into the release handle opening 202 and pulling up on the bottom of the release handle 200 so as to cause the release handle 200 to rotate about the release handle pin and bushing assembly 204. Such action places pressure on the bottom of a release pivot arm 206 causing the arm 206 to rotate about release pivot arm shaft 208 in a counter-clockwise direction when viewed in Figure 21. Such action generates retracting pressure on release pivot pin 210 so as to withdraw the top member locking pin 212 from the locking pin tapered hole 215 thereby allowing the top unit 16 to rotate about pin 217 and collapse to the position shown in Figure 20.

The release pivot arm 206 is biased to automatically relock the entrance unit pin to the operating position shown in Figure 19. This occurs when the collapsed arms are lifted up into the operating position, because of the tension from released pivot arm return spring 218 acting on release pivot arm 206 which causes the locking pin 212 to move back into tapered hole 215.

The support posts 18 illustrated in Figure 21 may include an alarm activation switch 222. The alarm activation switch 222 closes a low-voltage circuit when depressed by release pivot arm 206 so as to activate the alarm 224. Once the alarm 224 is activated an audible noise is emitted to signal staff or management that the emergency feature of the unit has been engaged.

Alternatively, the emergency release mechanism described above can be made inoperable through the use of a release mechanism lock out 226. The release mechanism lock out 226 shown in Figure 21 may consist of a cabinet style key activated lock which is adapted to be turned or rotated by a key to a locked position so as to move a locking plate into the travel path of the top locking pin 212 as illustrated by the phantom lines so as to prevent the locking pin 212 from being removed from the locking pin tapered hole 215.

Figures 22 - 26, inclusive, illustrate means or structure to minimize the possibility that a person may be trapped between two sets of barrier means as referred to earlier.
In other words, the device now has a mechanical means to allow a person to pass through a barrier arm provided that the preceding arm has been displaced.

A retaining spring 213 manufactured from spring steel can be utilized so as to set a barrier arm in a"released mode" as a result of movement or displacement of a preceding barrier arm. Such spring 230 would normally only appear on the second barrier arm assembly 34 and if installed, barrier arm assembly 36, except where the first barrier arm assembly 32 has an installed solenoid used in conjunction with a remote release feature such as a card reader or the like, in which event the retaining spring 230 would also be applicable to the first barrier assembly 32.

More specifically the retaining spring 230 has at one end thereof a flat securing face 232 which is adapted to be secured to main base plate 30 by means of securing screws 240. The other end of the retaining spring 230 includes a suspended end which is sprung to operate with upward pressure or biasing force as a result of forces provided by spring tension area 234. Suspended end 246 includes an opening ramp face 236, spring top surface 244 and closing ramp face 238 along with retaining edge 242.
The retaining spring 230 illustrates one type of spring that can be utilized but should not be limited thereto as counter balanced type of device or spring loaded form plate or various other configurations can be utilized within the scope of this invention.

Figure 23 illustrates a typical second or third barrier arm assembly 34 or 36 with the retaining spring 230.
The second or third barrier arms 22 or 24 have been drawn with hidden or phantom lines to assist in establishing the spatial relationship between the rotor bottom plate 42b or 42c along with second and third barrier arms 22 or 24. The rotor stop block 54 is secured by means of welding or other fastening means to the rotor bottom plate 42.
However, rotor stop block 54 is shown in solid lines to assist in the understanding to be described herein. Figure 23 shows a barrier arm assembly in the normal "at rest"
position.

The retaining spring 230 is secured to the rotor bottom plate 42b or 42c by means of securing screws 240 as shown. For simplicity the base plate stop 52 has not been shown in the figures, although the base plate stop 52 is utilized as previously described.

The suspended end 246 of retaining spring 230 is applying upward pressure on pivot stop bar 72 as shown in Figure 23. More specifically, Figure 23 shows that there is contact between the bottom of pivot stop bar 72 and the spring top surface 244 in the normal "at rest" position such as shown in Figures 19 and 23.

Figure 24 illustrates a disengaged pivot stop bar 72 position where the rotor release rod 66 has been activated by movement of a previous barrier arm whereby rotor release rod 66 has drawn rotor release block 78 from its rest position as shown in Figure 23 and caused the pivot cam arm 68 to be displaced and thereby disengage the pivot stop bar 72. The rotor bottom plate 42 has not yet moved from its initial position shown in Figure 23 since no contact has yet been made with barrier arm 22/24.

The displacement of the pivot cam arm 68 causes the pivot stop bar 72 to rotate away from the rotor stop block 54 a sufficient distance to allow the spring top surface 244 to move upwards thereby permitting retaining edge 242 to move upwards and alongside or against the pivot stop bar 72. This action assists in minimizing the possibility of an individual being accidentally trapped between two sets of barrier means.
Figure 25 illustrates the return of rotor release block 78 to its original "at rest"
position when the previous barrier arm returns to a closed position. Figure 25 also illustrates that the second or third barrier arm 22, 24 continues to be at rest since it has not yet been contacted by an individual. However, the pivot stop bar 72 is held in a displaced position by retaining edge 242; accordingly pivot cam arm 68 does not return to its initial rest position against rotor release block 78. This minimizes the possibility of a person being trapped between two sets of barrier means. More specifically, the activation or displacement of the prior barrier arm has caused the pivot stop bar 72 to be positioned in an unlocking or open position and the retaining spring 230 is holding pivot stop bar 72 in such position by means of the retaining edge 242.
It should also be noted that the barrier arm 22 or 24 in both Figure 24 and 25 has not yet been moved and accordingly the rotor stop block 54 has also not yet been moved.
However, the spring top surface 244 has moved upwards in both Figures 24 and 25 and accordingly the distance between the edge 53 of rotor stop block 54 and edge 243 of spring top surface 244 appears to be and is different in Figures 23 than that shown in Figures 24 and 25.

Figure 26 illustrates the access control device when a barrier arm such as barrier arm 22 or 24 is displaced from its rest position. As the user moves barrier arm 22 or 24, rotor bottom plate 42 begins to rotate in a clockwise direction when viewed in Figure 26 so as to rotate and bring the rotor stop block 54 into contact with opening ramp face 236 of the retaining spring 230. As the rotor stop block 54 continues to rotate, the suspended end 246 of the retaining spring is depressed to the extent that retaining edge 242 drops below the pivot stop bar 72 thereby allowing pivot stop bar 72 to come into contact with the end of rotor stop block 54 because of the biasing force generated by spring 73. The bottom of rotor stop 54 is slightly lower than the bottom of the pivot stop bar 72 so that the rotor stop block 54 may push down on the spring top surface 244.

As the barrier arm 24 or 24 continues to be displaced or rotated in a clockwise fashion, the rotor stop block 54 continues to rotate so as to travel across the spring top surface 244, and then down the closing ramp face 238 of the retaining spring.
As this occurs, pivot stop block 72 moves to its normal at rest position as shown in Figure 23.

More specifically as barrier arm 22 or 24 returns back to its normal rest position, rotor stop block 54 travels across suspended end 246 of retaining spring 230 in a counter-clockwise direction. As the rotor stop block 54 travels across suspended end 246 of retaining spring 230, it applies pressure on the various faces and the suspended end 246 is displaced downward and allows the rotor stop block 54 to return to its original rest position as shown in Figure 23.

As the barrier arm 22 or 24 moves to its closing position, rotor stop block 54 passes by and displaces pivot stop bar 72 when it is returning to its rest position. The displacement of pivot stop block 72 is not sufficient to allow the suspended end 246 to rise up and allow the retaining edge 242 to again hold pivot stop bar 72 in a preset condition. Spring 73 biases the pivot stop bar 72 towards rotor stop block 54.

Figure 27 illustrates a further alternate embodiment of the access control device 10. In the embodiment illustrated in Figure 27 a protruding rail 250 having a generally U-shaped configuration is used in place of the guide rail 19 shown in Figure 12. The collapsible rail 250 is secured to the top member 252 such that when moving the access control device shown in Figure 27 to the collapsed position of Figure 28 the clearance between the partition members is sufficient to meet code requirements such as handicap code requirements or fire exits requirements. Under normal circumstances the three barrier arms on one partition shown in Figure 27 is sufficient to allow passage of pedestrians, wheelchairs, strollers and in some cases shopping carts, without the need to collapse rail 250.
The collapsible rail partition 254 operates in the same manner as the standard barrier arm partitions with respect to the collapsing means shown in Figures 19, 20 and 21. Top member 252 is free to rotate in the manner similar to that shown Figure 21 by engaging collapsible rail handle 256 as previously described. However, the other methods of achieving the rotational displacement of the collapsible rail may be utilized by a multitude of means for releasing the top member 252 in a rotational fashion about pin 217.

One advantage of utilizing a collapsible rail partition as shown in Figure 27 relates to its simplicity of manufacture thereby being less expensive to produce than any regular barrier arm configurations shown in the previous drawings. However, all of the features of the regular barrier arm system as described herein will accommodate the passage of most patrons.
Various embodiments of the invention have now been described in detail. Since changes in and/or additions to the above-described best mode may be made without departing from the nature, spirit or scope of the invention, the invention is not to be limited to said details. Specifically, suggested components assembled in suggested mechanical relationships have been described herein to obtain the benefits of the invention, however, it should be understood that various different components and alternate modes of assembly may be used to achieve the benefits of the same invention without diverging from the invention disclosed herein.
