Description
- The present invention relates to a barrier apparatus. More specifically the present invention relates to a portable, temporary, barrier apparatus.
- Retractable barrier apparatuses are known. These apparatuses are commonly used in airports and shopping centres for managing and directing queues. Known retractable barrier apparatuses comprise a housing supported by a base member. When in use the base member is positioned on the floor and the housing extends upwards. The apparatus further comprises a spool rotatably supported within the housing. A ribbon or belt is wound around the spool and may be dispensed from the spool, through an aperture in the housing, to provide a barrier. A biasing means is provided within the spool which biases the spool to retract ribbon into the housing. As the spool assembly and biasing means are located at the top end of the housing, the centre of gravity of the apparatus is relatively high. Consequently, the barrier is more vulnerable to being knocked over. Due to its high centre of gravity such barriers are not well suited for use outdoors where they may be exposed to high winds, for example.
- Additionally, it is common for the ribbon to twist or fold as it is rewound onto a spool. A twist or fold occurring in dispensed ribbon will prevent continuous, smooth recoiling of the dispensed ribbon. In certain cases a twist or fold in the ribbon may cause the spool to jam, thereby preventing any further recoil or dispense of ribbon.
- It is an aim of the present invention to obviate or mitigate one or more of the aforementioned disadvantages.

- An embodiment of the invention will now be described by way of example only, with reference to the accompanying drawings in which:
-
FIG. 1 a provides a frontal view of a barrier apparatus; -
FIG. 1 b provides a vertical section view taken along line A-A′ of the barrier apparatus ofFIG. 1 a; -
FIG. 2 provides a perspective view of the barrier apparatus ofFIG. 1 a and 1 b; -
FIG. 3 a provides a perspective view of a belt feed-control device for a barrier apparatus; and -
FIG. 3 b provides an exploded view of the feed-control device ofFIG. 3 a. -
FIGS. 1 a, 1 b and 2 provide frontal, vertical section, and perspective views, respectively, of abarrier apparatus 1. Thebarrier apparatus 1 comprises abase 2 and asupport frame 46 fixed to thebase 2 and extending upwardly therefrom. Aspool assembly 3 is supported upon theframe 46 and thebase 2 andframe 46 are enclosed by ahousing 15. An upper portion of theframe 46 comprises ahandle portion 25 for transporting theapparatus 1. Thesupport frame 46 is connected to, and extends from, thebase 2. Theframe 46 comprises fourleg members 61 and aring member 63. Eachleg member 61 has a first end connected to thebase 2 and a second end connected to thering member 63. Thehandle 25 is connected to thering member 63 by a plurality of connectingmembers 65 extending radially outwards from thering member 63. - The
spool assembly 3 comprises first andsecond spools 5,7. Wound around the first spool 5 is a first ribbon orbelt 13, whilst a second ribbon orbelt 14 is wound around thesecond spool 7. Thefirst belt 13 andsecond belt 14 are each provided with aconnector element 47 on their respective free ends, although only theconnector element 47 belonging tofirst belt 13 is shown inFIG. 1 b. Theconnector elements 47 of eachbelt connector elements 47 are also suitable for connecting the belts to buildings, fences or other structures. - The
apparatus 1 further comprises two biasing means in the form of first and second recoil springs 17,19, which are both located within thebase 2. Thefirst spring 17 is coiled around afirst drive shaft 21 and connected between thebase 2 and thefirst drive shaft 21 to provide a rotational biasing force to thedrive shaft 21. Thefirst spring 17 is thus connected to the first spool 5 by means of thefirst drive shaft 21. Thesecond spring 19 is coiled around thefirst drive shaft 21 and asecond drive shaft 23, and is connected between thebase 2 and thesecond drive shaft 23 to provide a rotational biasing force to thesecond drive shaft 23. Thesecond spring 19 is thus connected to thesecond spool 7 by means of thesecond drive shaft 23. Thefirst spring 17 biases the first spool 5 to rewind thefirst belt 13 onto the first spool 5. Thesecond spring 19 biases thesecond spool 7 to rewind thesecond belt 14 onto thesecond spool 7. The biasing force generated by thefirst spring 17 is transmitted to the first spool 5 by means of thefirst drive shaft 21 and the biasing force generated by thesecond spring 19 is transmitted to thesecond spool 7 by means of thesecond drive shaft 23. Thefirst drive shaft 21 has a smaller external diameter than the internal diameter of thesecond drive shaft 23, such that theshafts first drive shaft 21 extends through thesecond drive shaft 23. - The ends of each
drive shaft respective springs shaft 21 is rotatably supported by a firstupper bearing 71 housed within the first spool 5, and a firstlower bearing 73 housed within thebase 2. Thesecond drive shaft 23 is rotatably supported by a secondupper bearing 75 housed within thesecond spool 7, and a secondlower bearing 77 housed within thebase 2. - The first spool 5 is rotatably supported within a
first spool housing 9 and thesecond spool 7 is rotatably supported within asecond spool housing 11. First, or upper,spool housing 9 has a central bore adapted to receive the upper end of thefirst drive shaft 21. Second, or lower,spool housing 11 also has a central bore which is adapted to receive the upper ends of both the first andsecond drive shafts drive shaft spool 5,7 may have teeth adapted to engage the splines on theshafts spool housing spools 5,7 extend into the bores to engage the splines on therespective shafts drive shafts respective spools 5,7. During assembly, thesecond housing 11 would be placed over thedrive shafts second spool 7 engage with the splines of the second,outer shaft 23, before thefirst housing 9 was then placed atop thesecond housing 11 with the teeth of the first spool 5 engaging the splines of thefirst shaft 21. The first andsecond spool housings receiver 49 suitable for receiving an optional belt feed-control device if control of the rate at which thebelts spools 5,7 is desired. - The
base 2 may comprise additional ballast such as, for example, aweight 27 in order to keep the centre of gravity of theapparatus 1 as low as possible. Theapparatus 1 may further comprise aretractable chassis 29 which can move in the vertical direction relative to thebase 2. Thechassis 29 has a first pair of wheels 33 (only one of the pair is visible) and a second pair of wheels 31 (only one of the pair is visible). The first pair ofwheels 33 may be fixed whilst the second pair ofwheels 31 may be mounted so as to be rotatable about the vertical. Theretractable chassis 29 forms part of aretractor assembly 39, which is operable to deploy and retract both pairs ofwheels base 2. - The
retractor assembly 39 further comprises alower lift tube 41 and anupper lift tube 42. Thelower lift tube 41 has a first end connected to theretractable chassis 29 and a second end having acam follower 44. Theupper lift tube 42 has a first end connected to an upper portion of theframe 46 and a second end having anothercam follower 44. A retractorassembly operating lever 45 has a handle at one end and a double-endedcam 43 at the opposite end. The handle is moveable between a first, upper position and a second, lower position. Moving the handle between its first and second positions pivots thelever 45, thereby effecting rotation of the double-endedcam 43. If the handle is moved into the first position (as shown inFIG. 1 b), thecam 43 rotates and a first end of thecam 43 engages thecam follower 44 of thelower lift tube 41 and thus pushes thefollower 44,lower lift tube 41 and thechassis 29 attached thereto downwards relative to thebase 2. Simultaneously, the other end of the double-endedcam 43 will co-operate with thecam follower 44 of theupper lift tube 42 to lift theupper lift tube 42, theframe 46 andbase 2 upwards relative to thechassis 29. The simultaneous movement of the upper andlower lift tubes - Moving the retractor handle to its second, lower position will rotate the double-ended
cam 43 so that one end of the double-endedcam 43 releases theupper cam follower 44, thereby allowing theframe 46 andbase 2 to move downwards relative to thechassis 29 under gravity. Thebase 2 will be lowered over thewheels wheels base 2. - A
suspension system 51 may be provided between theretractable chassis 29 and thebase 2. Thesuspension system 51 will dampen the relative motion between thechassis 29 andbase 2, especially during retraction of thechassis 29 andwheels base 2 and also act as a guide means to ensure the smooth transition between the deployed and retracted positions. Arod member 53 extends through a substantiallyvertical guide passage 55 within thebase 2 and has a lower end fixed to thebase 2 and anupper end 58 received in atower member 57 provided on theretractable chassis 29. A biasingmember 54 surrounds therod 53 and is located between thebase 2 andchassis 29. When the retractor handle is moved to the second position to retract thewheels frame 46 andbase 2 drop under gravity relative to thechassis 29. The biasingmember 54 will compress, damping the downward movement of thebase 2 relative to thechassis 29. As the biasingmember 54 is under compression in the second, retracted position, it biases thebase 2 andchassis 29 away from one another towards the first, deployed position. - As seen best in
FIG. 2 , thehousing 15 has arecess 91 defined therein to accommodate the handle of theretractor lever 45 when it is in the second position. In this way, the handle is not protruding from the housing when the apparatus is in position with its wheels retracted.FIG. 2 also illustrates that thehandle 25 may extend about the circumference of thespool housings apparatus 1 to be easily maneuvered from any angle. - In operation, the belts are deployed from their
respective spools 5,7 by pulling the free ends of the belts from openings in therespective spool housings spools 5,7 rotate and in turn rotate theirrespective drive shafts base 2. When the belts are to be retracted, their free ends or connectors are released and the recoil springs 17,19 apply a rotational force to thespools 5,7 via therespective drive shafts spools 5,7. The free ends or connectors are sized so that they cannot enter thespool housings housing - Referring now to
FIGS. 3 a and 3 b, an optional belt feed-control device 101 is shown which is suitable for attaching to thereceivers 49 on the first andsecond spool housings apparatus 1.FIG. 3 b provides an exploded view of the feed-control device 101 ofFIG. 3 a. When connected to areceiver 49 on aspool housing control device 101 is operable to control the rate at which a ribbon or belt is unwound from, and rewound onto, thespools 5,7 within thehousings - The feed-
control device 101 comprises a first finger or guide 102 and a second finger or guide 112. Thefirst finger 102 andsecond finger 112 are arranged relative to one another so as to define achannel 110 between them. Thechannel 110 is of a width suitable for receiving a ribbon or belt. Thefirst finger 102 is pivotally mounted about a first pivot axis on afirst pivot pin 104. Afirst portion 106 of thefirst finger 102 extends in a first direction away from thefirst pivot pin 104 and asecond portion 108 of thefirst finger 106 extends in a second, opposite, direction away from thefirst pivot pin 104. Thesecond finger 112 is pivotally mounted on a second pivot axis on asecond pivot pin 114 such that afirst portion 116 of thesecond finger 112 extends in a first direction away from thesecond pivot pin 114 and asecond portion 118 of thesecond finger 112 extends in a second, opposite, direction away from thesecond pivot pin 114. The first and second pivot axes are substantially parallel with one another. - The
first portions finger channel 110. The inner guide surface of one or bothfingers inspection aperture 170 so that the belt is visible and accessible through thefirst finger 102. The guide surfaces 150 a,150 b may be planar or alternatively, as is the case in the illustrated embodiment, they may undulate in the direction of their respective free ends 132,134 such that thechannel 110 is non-planar. Thesecond portions finger co-operable corrugations 120. In other words, the convex and concave sections which form thecorrugations 120 of thefirst finger 102 are the opposite of those sections of thesecond finger 112. Thecorrugations 120 in thesecond portions finger channel 110 and slow the rate at which the belt is dispensed from, or rewound onto, aspool 5,7. - The
first finger 102 further comprises alip member 122 which extends outwardly across thechannel 110 in a generally perpendicular direction relative to theguide surface 150 a of thefirst finger 102. Thelip member 122 has anaperture 160 which in use receives thesecond pivot pin 114, wherein thelip member 122 supports thesecond finger 112 and thesecond finger 112 may pivot a small amount relative to thefirst finger 102. Thefingers small gap 130 is defined between the upper surface of thelip member 122 and the lower surface of thesecond finger 112. Thelip member 122 prevents a belt dropping out of thechannel 110. - The feed-
control device 101 further comprises anattachment assembly 136. Theattachment assembly 136 enables the feed-control device 101 to be removeably attached to a barrier apparatus. Theattachment assembly 136 comprises ananchor member 141 and abase member 138. The first andsecond fingers base member 138 by way of the pivot pins 104,114. Theanchor member 141 is fixed to thereceiver 49 of the barrier apparatus, and thebase member 138 is then secured to theanchor member 141 by a suitable fixing means, such as by screw fixtures or by a snap fit between the base andanchor members anchor member 141 has fourapertures 1441,144 b defined therein (two of which are shown inFIGS. 3 a and 3 b). - Four
complimentary apertures FIGS. 3 a and 3 b), are defined in thebase member 138. - In assembling the
device 101 the first finger is fixed to thebase member 138 by way of thefirst pivot pin 104. Theanchor member 141 is fixed to thereceiver 49 around an opening in one of thespool housings base member 138 is then fixed to theanchor member 141, or else it can be fixed to theanchor member 141 in advance of attachment to the apparatus. A belt from one of thespools 5,7 is then pulled out of the opening in itsrespective housing attachment assembly 136. Whilst the belt is held against the retraction force of its respective biasing spring thesecond finger 112 is pivotably fixed to theattachment assembly 136 andfirst finger 102 by thesecond pivot pin 114, with the guide surfaces 150 a,150 b of thefingers channel 110 and the belt located in thechannel 110. Theconnector element 47 on the end of the belt is wider than thechannel 110 and so prevents the belt from retracting all the way into the spool housing if it is released. The feed-control device 101 is now able to control both the rate at which the belt is dispensed from aspool 5,7 and the rate at which the belt is rewound onto aspool 5,7. - To dispense the belt a user pulls on the
connector 47 to unwind the belt from one of thespools 5,7. As the belt is deployed it moves through thechannel 110. The user may pull the belt at an angle relative to a general plane of thechannel 110. As a result the belt within thechannel 110 will be forced against aninner guide surface second finger first portion finger first portion other finger first portions second portions channel 110 in the region of thecorrugations 120. As thesecond portions finger corrugations 120 frictionally engage or ‘pinch’ the belt within thechannel 110. Frictional engagement or ‘pinching’ of the belt by thecorrugations 120 will slow the rate at which the belt is deployed from thespool 5,7. Once dispensed the belt is secured to another barrier apparatus, or other secure structure, to form a temporary barrier. - When the barrier is to be moved, or is no longer required, the belt is recoiled onto the spool. To recoil a belt onto a spool the user will first release the secured belt from the other barrier apparatus or other secure structure. Usually, once released, the user releases their hold on the belt and allows the belt to rewind automatically under the influence of the
biased spool 5,7. Without the user holding the belt it may whip from side-to-side as it approaches and enters thechannel 110 in thefeed control device 101. As the belt passes through thedevice 101 it may be forced against theinner surfaces first portions second fingers fingers first portions fingers first portions second portions channel 110 in the region of thecorrugations 120 and thus selectively slowing the recoil of the belt onto its spool. As thesecond portions finger channel 110. Frictional engagement or ‘pinching’ of the belt by thefingers spool 5,7. - The
feed control device 101 not only slows the deployment and recoil of the belt but also prevents the belt from being rewound onto thespool 5,7 in a twisted, or folded, state. Thefingers channel 110 between thefingers - Although the preferred embodiment of the apparatus employs a ribbon or belt for forming the barrier, it will be understood that the apparatus may instead employ one of the following as the barrier: a chain, rope, band, tape or netting.
- It will be understood from the foregoing description that the rotational members and associated chassis and actuation mechanism are preferred, but not essential, components of the invention. Furthermore, although the description discloses rotational members in the form of wheels, it will be understood that other rotational members may be used. For example the rotational members may be rollers or castors. As with the wheels of the preferred embodiment, the rollers or castors may be fixed to roll in one direction, or may be mounted so as to be able to rotate about the vertical such that the roller or castor will automatically swivel, aligning itself to the direction in which it is moving.
- The biasing spring which biases the chassis and base away from one another may do so whilst located between the upper and lower lift tubes of the retractor assembly instead of directly between the base and chassis as in the preferred embodiment.
- Although the description discloses a barrier apparatus having first and second spools, it will be understood that the barrier apparatus may have any number of spools and associated belts. For example, third and fourth spools and belts may be provided. Alternatively, a single spool having a single belt may be provided.
- Although the description discloses that the first and second spools are located in stacked spool housings which are positioned on top of the main housing, it will be understood that any number of spools may be provided and that the spools may be positioned any height. For example a first spool may be provided on top of the housing, a second spool may be positioned at a point which is approximately half the height of the housing, and a third spool may be positioned at a point which is proximate to a base end of the housing.
- Although preferably one biasing means is provided per spool, it will be understood that any number of biasing means may be provided per spool. For example, the first and second spools may be non-rotatably connected and a single biasing means may be shared by a first and second spool such that the single biasing means biases both the first and second spools to rewind their respective ribbons onto the spools as one.
- Although preferably a first drive shaft connects a first spool to a first biasing means and a second drive shaft connects a second spool to a second biasing means, it will be understood that any number of drive shafts may be provided. For example, a single drive shaft may connect both the first spool and the second spool to the a single biasing means, or three drive shafts may be provided wherein each of the three drive shafts connects a respective spool to a respective biasing means. Each of these drive shafts may be arranged coaxially.
- Although the biasing member biasing each spool is preferably a recoil spring, it will be understood that alternative biasing means may be used such as, for example, a torsion spring. As an alternative to the biasing means the barrier apparatus may be provided with one or more motors that are operable to drive the drive shaft(s) and spool(s).
- Although preferably a retractor assembly operable to retract the one or more wheels, it will be understood that alternative means of anchoring the barrier apparatus in a position may be used. For example, one or more brake members that are operable to contact the one or more wheels to prevent rotation of the wheels may be provided. Alternatively, two or more extendible leg members that may be extended from the base structure to prevent barrier apparatus from being wheeled. Preferably, at least four retractable leg members would be provided.
- The belt feed-control device may be used with the barrier apparatus described, or may also be used with other temporary belt/ribbon barriers as well.
- Instead of a dedicated weight, the optional ballast in the base may be provided by filling the base with water or sand, for example.
- These and other modifications and improvements may be made without departing from the scope of the invention as defined in the appended claims.
