Definitions

  • This invention relates to a multiple arm turnstile wherein turnstile rotation necessary to bring one arm at a time to the operating position where said arm closes the passage guarded by the turnstile, is con­trolled by a suitably shaped cam which is keyed on the same shaft where the arms are mounted.
  • a pair of jaws cooperates with the above cam, each jaw being pivoted at one end thereof to the turn­stile frame, while the other end engages into a cam recess.
  • the jaws are connected to each other through resilient means adapted to keep said ends engaged within the cam recesses while allowing in any case the jaw to move apart from each other whereby the ends thereof can move out of the cam recesses where­upon the cam is enabled to rotate through the same angle an arm has to cover in order to get to the ope­rating position. In the latter position the jaws ends will have entered into abutment with a different pair of cam recesses.
  • the first of said operating steps to be performed is the unlocking step, which may be performed by means of a control pushbutton or by inserting a ticket, a magnetic card or the like in a reader device provided on the turnstile.
  • This operating step unlocks the turnstile locking mechanism whereby the second operat­ing step is enabled, i.e. pushing the turnstile arm all the way to the off position thereof, while the following arm comes simultaneously through to the operative position.
  • the turnstile gets ready for the next user.
  • the locking mechanism is an electro-magnetic brake.
  • the electro-magnetic brake is a locking mechanism whose action is limited, in that it cannot positively counteract a pushing action performed upon the arm which is in an operative position, even though said action is not overly rude. Accordingly, the turnstile can unlock and enable one or more people to go through even though the operation of inserting a ticket or magnetic card in a turnstile reader device has not been performed.
  • turnstile wherein the unique locking mecha­nism is adjustable according to need whereby a turn­stile may be set in such a way as to be unlocked under a limited intensity or a high intensity force, depend­ing upon the field of application of the subject device.
  • the turnstile resistance to unlocking may be varied within a range of values rang­ing from a completely loose to a completely locked turnstile condition.
  • the inventive turnstile as an access enabling device to a ski resort lift facility.
  • the turnstile resi­stance to unlocking should be limited, in that the turnstile should not become a dangerous obstacle for a user arriving at the turnstile location while wear­ing his skis, whereby he is in an unstable condition, due in some cases also to the arriving speed.
  • Another object of this invention is to provide a turnstile wherein selecting the allowable rotation direction is an extremely easy operation, owing to the provision of a unique mechanism which enables said rotation direction to be immediately set or modi­fied, without requiring any additional operation on the turnstile, such as for instance a partial or total disassembling thereof.
  • a further object of this invention is to provide a very sturdy turnstile construction, which is quiet in operation, whereby all the discomfort deriving from a noisy operation is done away with, said dis­comfort although being unessential from an operation standpoint still being considered by the users as an objectively negative factor.
  • the turnstile is shown to include a stationary support stand, shown in general at 10 and comprising a pair of support posts 12 fastened, at the lower end thereof, to base plate 13. To the upper ends of posts 12 there is fastened a substantially prism shaped box-like member 14 within which the va­rious turnstile motion control mechanisms are located.
  • figure 2 shows in general the several turnstile motion control mechanisms in the first embodiment.
  • a large plate 22 which supports the various mechanisms and is fastened in any known fashion within box-like body 14.
  • outer plate 20 which closes box-like body 14 and whose removal allows the interior of the turnstile to be reached for the routine maintenance operations which, on the other hand, owing to the original arrangement of the mechanisms of this invention are substantially nil. However, access to the mechanisms may be gained from the top as well.
  • a three lobed cam 24 substantially centrally located relative to plate 22, and comprised of a suitably contoured plate lying in a plane parallel to the plane of plate 22.
  • Cam 24 is mounted on a shaft 26 which in turn, as it will become more apparent in the following, is fastened to dome member 18 carrying arms 16.
  • Cam 24 is peripherally provided with three equal­ly spaced recesses 28 in the circumferential direction, located substantially 120° apart from each other. As it is apparent, recesses 28 are in the same number as arms 16, and the latter will be offset of the same angle.
  • said recesses have a substantially semicircular outline, and the connecting regions 30 between them and the periphery of the cam are rounded according to an arc of a circle, since the cam, per se, must enable rota­tions of the turnstile arms in both directions, just for the purpose of obtaining a two-directional type turnstile. Selection of the rotation direction is performed by means of a mechanism which is still an object of this invention, and which will be described more particularly in the following.
  • Cam 24 has associated therewith a pair of jaws 32 each having one end thereof pivoted around pivot pin 34 integral with plate 22, while the opposite end of said jaws 32 is in engagement against the periphery of cam 24.
  • a ball bearing 36 whose function is to provide for maximum reduction of friction of ends 32 against the periphery of cam 24 as the latter rotates, in order to assist the rotation of said cam.
  • Jaws 32 are connected to each other by means of a spring 38 having both ends thereof fastened to said jaws, for instance by means of a bolt 40.
  • Spring 38 is provided to make both jaws 32 to converge towards each other, whereby the jaws ends abutting against cam 24 are biased against the peri­phery thereof.
  • cam 24 provides a resi­stance action in both directions; as it is apparent from figure 2, the ends of jaws 32 are engaged within cam recesses 28, whereby a cam rotation can take place only by making said ends to come out of recesses 28.
  • Jaws 32 owing to the action of spring 38, already by themselves oppose a certain degree of resistance to rotation of cam 24 for the first 60° of rotation, but, as it will become more apparent in the following, the turnstile of this invention is provided with a new and original mechanism allowing the amount of said resistance to be adjusted. This is because, as it has already been mentioned, according to the loca­tion of use of the turnstile, the desired turnstile rotation resistance may be different.
  • the subject mechanism includes a disc 43 fixedly mounted on shaft 26, and having knurled regions 42 on the periphery thereof, close to the base faces of the disc. Upon the non-knurled region there is fitted a rubber ring 44, projecting slightly relative to the circumference of disc 43.
  • the rotation direction se­lecting mechanism further includes a pair of sector­-shaped plates 46 which are provided to cooperate with disc 43, one alternate to the other.
  • sector shaped plates 46 is par­tially knurled.
  • sector shaped plates 46 are of the same height as disc 43, and said plates are knurled only at the bases thereof, for the same height of the knurled regions 42 of disc 43, whereby the two knurled regions of a plate 46 can engage against knurled portions 42 of disc 43.
  • sector shaped plates 46 are pivoted on pivot pin 50, whereby said sector plates 46, as it will be explained in the following, may come into engagement with disc 43 or be moved away therefrom.
  • the line connecting pivot pins 50 where sector plates 46 are pivoted is offset relative to shaft 26 whereby, in case a sector plate 46 is brought closer to discs 42 and comes into engagement therewith, as it is the case for left hand side plate 46 in figure 8, the allowable rotation direction is the clockwise direction, as it is shown by arrow F in figure 8.
  • said plate 46 mentioned above rotates according to the direction of arrow G around pivot pin 50, and arm 16 which is in an operative position, i.e. a position inhibiting the restrained passage, is allowed to move to an off position.
  • the rotating direction selection mechanism includes means adapted to control said motions of sector plates 46.
  • Said means comprise, for each sector plate 46, an electromagnet 52 located behind sector plate 46 relative to disc 43.
  • electromagnet 52 associated with said plate is actuated in such a way as to drive the moving member 54 thereof towards the inside of the electro­magnet core, as it is shown for left hand side plate 46, in Figures 2 and 8 against the bias of a spring 56, which, as it is shown in Figure 9, is connected at one end thereof to a pin 58 fastened to the end of electromagnet 52 moving member 54, and at the opposite end to a pin 60 fastened to support plate 22.
  • the rotation direction selecting mechanism of the turnstile of this invention is completed by a pair of pins 64 integral with plate 22, and acting as limits to the stroke of plates 46, when electromagnet 52 gets de-energized.
  • Control of the above mechanism is extremely simple, in that it will be sufficient to provide, in a suitable position, a switch adapted to actuate either one of the electromagnets 52, according to the desired direc­tion of rotation.
  • the mechanism adapted to vary the turnstile resi­stance to rotation in the permitted direction uses a hydraulic circuit, shown in Figure 5 and described in the following, which is suitably controlled to drive a hydraulic piston 64 from a first limit condition wherein its piston rod 66 is completely locked, to a second limit condition wherein its piston rod 66 can move freely.
  • piston rod 66 of hydraulic piston 64 abuts against a suitably shaped small block, shown at 68 ( Figure 7a), having a contour­ed shape on side 73 where piston rod 66 comes into engagement therewith, while at the other end the block ends in a fork 69 surrounding jaw 32 and being pivoted around pivot pin 71 of bearing 36.
  • Small block 68 is preferably metal, and it substantially provides a pivoted joint between piston rod 66 and jaw 32 upon rotation of the turnstile.
  • Hydraulic control circuit of piston 64 is shown in Figure 5, in block diagram form, while Figures 3 and 4 show detailed construction drawings thereof.
  • Said hydraulic circuit includes a one-way or check valve 70, a flow control valve 72, and eventually a pressure control valve 74, connected in parallel with each other.
  • said one-way valve 70 may be a globe check valve
  • flow control valve 72 may be a valve provided with a precision throttling orifice
  • the pressure control valve may be a directly actuated valve (by means of a spring), or else an indirectly actuated valve (by means of a suitable auxiliary valve provided for the purpose).
  • hydraulic control circuit of piston 64 includes an auxiliary piston 76, whose function is to bring piston 64 back to initial conditions, each time it has been actuated in order to enable the rota­tion of the turnstile.
  • auxiliary piston 76 includes a piston rod 78 having a spring 80 coiled therearound, said spring abutting, at one end against a face of the cylinder of piston 76, while at the opposite end it abuts against head 82 of rod 78.
  • the turnstile rotation resistance may be calibrat­ed as follows. First of all, flow control valve 72 is completely closed by means of a suitable electric signal, said valve being actually an electrically operated valve.
  • Pressure control valve 74 is similarly actuated although it is manually closed, since it is a mecha­nically operated valve.
  • stem 66 of piston 64 is locked, even in the case, in an attempt to rotate the turnstile, a strong force P ( Figure 5) is applied to said stem 66 by end 36 of jaw 32.
  • a strong force P Figure 5
  • the oil contained within the cylinder of piston 64 cannot flow out neither through single-acting valve 70 nor through flow control valve 74, in that said valves are closed.
  • calibrating operation may be performed either when installing the turnstile, or during operating of the same, if particular reasons require the turnstile to be adjusted for the particular use said turnstile has been assigned to.
  • Turnstile locking and unlocking may be performed, independent of the condition of valve 74 which will never be totally open during normal operation, through electrically operated valve 72 adapted to be opened or closed by means of electric pulses.
  • Electrically operated valve 72 may be set to remain locked or open in case of a power failure, and such setting may be provided in a known way.
  • the turnstile remains in the locked condition and unlocking can be performed through adjustment of valve 74, as previously mentioned.
  • valve 72 is not open or opening thereof is delayed, in any case valve 74 enables the turnstile to rotate, provided said valve is in a partially open position.
  • a single hydraulic piston 64 has been provided in association with turnstile jaws 32.
  • a pair of hydraulic piston may be provided, each one of them being associated with one of the jaws 32.
  • the turnstile according to the invention has been described and shown as having a substantially vertical plate 22 for supporting the various turnstile mechanisms, but this arrangement should not be consi­dered as a limitation, in that the same inventive concept may be applied to a turnstile wherein said plate has a different position. It had also been added that, with a non-vertically arranged plate, a slight modification of the rotation direction selected mecha­nisms was sufficient. That statement will now become apparent if reference is made in particular to Figures 8 and 9.
  • either one of sector plates 46 comes into engagement with disc 43 under the action of gravity. Assuming that the plate is substantially horizontal, it will still be possible to provide for engagement of either one of sector plates 46 with disc 43.
  • each sector 46 has a spring connecting extension 62 thereof to the body of electro-magnet 52 whereby, when the latter is energized, and moving member 54 thereof collapses within the associated core, said spring makes sector plate 46 to rotate towards disc 43 until said plate comes into engagement with the latter.
  • the spring constant of the spring mentioned above will have to be lower than the spring constant of spring 56 of this embodiment. In fact, if this is not the case, when electro-magnet 52 is energized, said spring 56 would not be able to make electro-magnet 52 moving member 54 to extend out of the core associated therewith, in order to disengage sector plate 46 away from disc 43.
  • the three-lobed cam has been replaced with a set of three ball bearings 82, only two of them being shown in the subject Figures.
  • Ball bearings 82 are positioned 120° apart from each other and, as it is apparent in particular from Figures 11, 14 and 15, they are supported on the lower side of a support disc 84 rotating mounted on shaft 26.
  • a positioning member 86 comprising an arc-shaped arm whose concave side faces towards ball bearing 82.
  • Positioning member 86 is fastened to, or integral with, rod 66 of piston 64 which, owing to the fact that piston rod 66 can move back and forth, allows the turnstile to rotate. What has been described above is shown in sequence in Figures 12 and 13 wherein substantially half of a complete rotation of arm 16 is shown, always according to the direction of arrow F. In particular, the position shown in Figure 13 is close to the intermediate position within a complete rotation corresponding to complete collapsing of piston rod 66 within its cylinder, which takes place when bearing 82 is positioned facing the median region of positioning arm 86. Owing to the presence of compen­sating piston 76, piston rod 66 can subsequently move forward whereby arm 86 is brought back to the starting position thereof.
  • flow control valve 74 is missing, in that it has been replaced by further different means, to be described in the following.
  • a single disc-engaging plate 46 is provided, whereby the subject turnstile is a single-direction turnstile.
  • the subject turnstile is a single-direction turnstile.
  • a second plate 46 is provided, a two-direction turnstile is easily obtained, similar to the first embodiment.
  • the means mentioned previously to enable a turn­stile rotation in any case, said means being used, for instance, as it was mentioned above, in a turnstile provided at a ski resort lifting facility, include in this case yielding and adjustable connecting means provided between knurled disc 43 and ball bearing 82 support disc 84, as it appears in particular from Figures 11, 14 and 15.
  • Said means include three balls 88 inserted within suitable channels 89 provided inside knurled disc 43 and positioned substantially 120° apart from each other.
  • Each one of the balls 88 is retained within a seat 90 of disc 84, under the action of a pin 94 subjected, at an enlarged cross section head 92 thereof, to the action of a spring 96 whose opposite end abuts against the inner face of a thread­ed locking ring 98 which is threaded on the upper end of a substantially cylindrical body 100 within which pin 94 can move, while projecting out of locking ring 98 through an opening of the latter.
