Abstract
A collapsible A-frame (100) for use in a road barrier assembly (300) has an upper support means (152) adapted to support a barrier member (200) of the barrier assembly, and has first and second legs (110, 120) pivotally connected to a lower end of the upper support means. There is a cross member (130) pivotally connected to the first leg (110), and the second leg (120) can secure a free end (220) of the cross member (130) thereto by an interengagable male and female type joint assembly (210, 320). This occurs when the A-frame (100) assumes an expanded portion after the first and second legs (110, 120) have been pivoted apart and the cross member (130) has been pivoted away from the first leg (110).
Description
- The present invention relates to a collapsible A-frame for use in a road barrier assembly.
- Known road barrier assemblies come in many different forms and sizes. A common form comprises a pair of A-frames that support a barrier member, typically an elongated beam. These A-frames have a fixed structure that, when stored after use, take up a large volume and so may increase transportation and storage costs. Their fixed structure also imposes burdens on workers who have to unload, convey and locate the A-frames on a work site.
- It is an object of the present invention to overcome, or at least substantially ameliorate, the aforementioned disadvantages of the prior art.
- According to one aspect of the invention there is provided a collapsible A-frame for use in a road barrier assembly, comprising an upper support means adapted to support a barrier member of the barrier assembly, first and second legs pivotally connected to a lower end of the upper support means, and a cross member pivotally connected to the first leg, the second leg including means for securing a free end of the cross member thereto when, in assuming an expanded position of the A-frame, the first and second legs have been pivoted apart and the cross member has been pivoted away from the first leg.
- Preferably, the upper support means includes an aperture through which the barrier member can be located, the aperture being defined by at least two vertical support members separated by at least a bottom horizontal support member.
- It is preferred that the free end of the cross member is, when the A-frame is in the expanded position, secured to the second leg by an interengagable male and female type joint assembly.
- In a preferred form, the free end of the cross member has a groove which is engagable to a projection on the second leg, such that in use the application of downward force on the cross member causes the groove to engage the projection.
- Preferably, the projection comprises a cross-sectional T shaped male portion connected to the second leg, and there is a stop portion at a lower end of the projection, the groove at the free end of the cross member comprising a cross-sectional T-shaped female portion so as to engage the male portion of the projection, such that in use the male portion of the projection is inserted into the female portion of the cross member and wherein the stop portion prevents further insertion.
- It is preferred that the first and second legs are, when the A-frame is in a collapsed position, secured together by an interengagable ball and socket type joint assembly.
- In a preferred form, the first leg has a socket means which is engagable to a ball means on the second leg when, in assuming the collapsed position of the A-frame, the cross member has been pivoted between the first and second legs and the first and second legs have been brought together.
- Preferably, the ball means is located below the projection on the second leg.

FIG. 1 depicts twoA-frames 100 assembled in conjunction withbarrier 200 to formroad barrier 300. Each A-frame 100 has been constructed so as to be lightweight, compact and collapsible. Each A-frame 100 possesses afirst pivoting leg 110 and asecond pivoting leg 120. Thefirst pivoting leg 110 has attached to it a pivotingcross member 130 which pivots atpoint 135 and has a free end that is engaged by a projection 210 (shown in detail inFIGS. 10 to 12 ) and by astop 150. Each set oflegs type joint assembly 140 for maintaining the legs in a collapsed position as depicted inFIG. 2 . Each A-frame, In addition to first andsecond legs pivot points legs vertical support members horizontal support members aperture 158, through whichbarrier member 200 is inserted and seated. In addition, certain other types of barriers and/or other instruments, such as warning lights, can be attached to the top of the A-frame through ahole 160. -
FIGS. 2 , 3, 4, 5, and 6 all show the same embodiment of the invention in its varying stages of assembly from a collapsed position to an expanded position.FIG. 2 depicts the A-frame in its most collapsed and secured form. In this form, thelegs joint assembly 140 which, in this particular embodiment of the invention, comprises a ball means and a socket means that, when interengaged, form a secure, yet reversible, connection. In other embodiments of the invention,horizontal support members cross member 130 andsecond leg 120. -
FIG. 3 depicts a first stage in assembling the A-frame for use. In this stage,legs pivot points legs feet legs FIG. 3 . -
FIG. 4 depicts thecross member 130 being pivoted atpoint 135 in a downwardly direction. Again, thepivot point 135 can be made such that it ceases to pivot at a predetermined angle. -
FIG. 5 depicts the almost finally assembled A-frame. In particular, it depicts the free end ofcross member 130 in dose association with a cross sectional T shaped male portion ofprojection 210 and stop 150. With the downward application of force oncross member 130, the male portion ofprojection 210 becomes inserted into a cross sectional T shaped groove 320 (shown in detail inFIGS. 7 to 9 ) at thefree end 220 of thecross member 130, and the free end becomes seated onstop 150. - Such a configuration, where the
cross member 130 is seated onstop 150, is depicted inFIG. 6 . In this configuration, the cross member is horizontal so as to increase the stability and strength of the A-frame. -
FIGS. 7 to 12 depict various features of thefree end 220 of thecross member 130 and of the Tshaped projection 210. - As shown in
FIG. 7 , thefree end 220 ofcross member 130 is cut at an angle such that, when the cross member is horizontal, thesplit face 310 touching thesecond leg 120 is parallel with theleg 120, thus leaving little or no gap betweencross member 130 andsecond leg 120. The T shapedgroove 320 extends throughout the thickness ofcross member 130 as depicted inFIGS. 8 and 9 . - T shaped
groove 320 is adapted to receive within it the Tshaped projection 210 of thesecond leg 120. The Tshaped projection 210 is connected toleg 120 along the base of the T, thereby forming theprojection 210 as depicted inFIGS. 10 , 11 and 12. Directly below the Tshaped projection 210 is thestop 150. Stop 150 prevents the Tshaped projection 210 from passing completely through the Tshaped groove 320. It thereby causes the engaged cross member and leg assembly to be static atstop 150. - In order that the A-frame be easy to handle, it is preferable to include means for keeping the
legs cross member 130 together whilst the A-frame is in its collapsed state. For that purpose, ajoint assembly 140 is utilised. Thejoint assembly 140 is shown separated inFIG. 1 and is shown engaged inFIG. 2 . In the present embodiment, the joint assembly comprises a ball means and a socket means which engage each other with sufficient force to hold the legs and cross member together such that they can be handled as if they were a long, thin article. - The present embodiment described herein utilises injection moulded plastic pieces for assembly into the collapsible A-frame. Further, rather than utilise solid lengths of injection moulded plastic, the lengths of plastic feature a zig-
zag backbone 330 withpanelling FIG. 13 . This results in extremely lightweight yet strong lengths of plastic pieces. - Numerous modifications and alterations may be devised by those skilled in the art without departing from the spirit and scope of the present invention. Thus while the present invention has been shown in the drawings and described above with particularity and detail, it will be apparent to those of ordinary skill in the art that numerous modifications, including but not limited to, size, materials, shape, form, function and manner of operation, assembly and use, may be made without departing from the scope or ambit of the invention.
