Definitions

  • the present invention relates to an improved riot shield and, in particular, to a riot shield which can be used in combination with a plurality of other riot shields to form a strong, secure and effective defensive wall between riot control officers and rioters.
  • An officer equipped with a riot shield can protect himself from attack, and to a certain extent he can protect brother officers behind him not equipped with riot shields.
  • an officer is always vulnerable to attack from the side or from behind. Accordingly, officers are trained to work as a group in a riot situation and to use their riot shields to secure a tactical advantage over the rioters.
  • Those officers in the first few ranks of a company are equipped with riot shields which they use to form a defensive wall between themselves and the rioters.
  • Those officers not equipped with riot shields shelter behind the officers holding up the defensive wall and follow the wall into the rioters to impose control and restore peace on the situation.
  • the wall affords complete protection as the officers move into the rioters and allow them to adopt various tactical formations such as wedges, pincer movements, etc.
  • An example, of one such tactical move facilitated by the use of riot shields to form a defensive wall is that of a snatch to take trouble makers and ringleaders out of the riot.
  • a snatch squad of officers shelters behind the defensive wall and when an opportunity presents itself a section of the defensive wall is opened to allow the snatch squad through. Once the snatch is completed the officers can return through the opening with their prisoner and the opening is then closed to prevent other demonstrators from following the snatch squad through.
  • a riot shield consists of a polycarbonate sheet having two handles secured to the back of it which enable an officer to carry the riot shield on his left arm, whilst leaving his right arm free.
  • Polycarbonate material is lightweight, yet tough and very shock resistant. It is also fire resistant. In addition, it can be transparent. All of these features make it suited to use as a riot shield - it affords good protection against attack, either directly or by missiles and projectiles, whilst being easily carried, and allows an officer to see the situation faced through it.
  • polycarbonate shields can be brittle and prone to cracking after extended use.
  • polycarbonate shields break, they break into shards and in a riot control situation this can be highly dangerous for both the officers and rioters. Consequently, there is a need to replace polycarbonate riot shields to prevent breaking after deterioration through extended use.
  • polycarbonate riot shields are typically required to be around 4mm thick and this can make them heavy.
  • EP0255761 describes a polycarbonate riot shield which is capable of interlocking with an adjacent riot shield to provide greater strength than other prior art shields. These shields may be linked together by interlocking channels formed in the shields. Although these shields are superior to non-locking or flat riot shields, formation of channels in the shields during manufacture may cause stress in those areas.
  • Polycarbonate is prone to cracking at points of stress.
  • the areas around the channels in the shield described in EP0255761 are subjected to further stress in use, as adjacent shields interlock mechanically in those areas when a wall of shields is formed. Further, stress is unavoidably induced in the polycarbonate material when the channels are formed during manufacture.
  • It is an object of the present invention to provide a riot shield comprising a planar shield member and at least one handle secured to the back of the shield member wherein the shield member is formed from a plastics material that is capable of deforming plastically upon impact.
  • the plastics material comprises a mixture of polycarbonate and silicone.
  • the shield member is formed from Lexan® 9030 FA XR.
  • the riot shield can be releasably secured to another riot shield on each side to form a strong secure and effective defensive wall.
  • a riot shield comprising a planar shield member and at least one handle secured to the back of the shield member, wherein integral linking means is provided on each of two opposing sides of the shield member, whereby the shield member can be releasably interlinked with the linking means of a second riot shield.
  • each linking means comprises an open channel section integrally formed in a side of the shield member, which channel section opens towards the back of the shield member, and locking means which lies in or over the open channel section and is adapted in use to lock the open channel section of a second riot shield in the said open channel section.
  • two or more riot shields are secured together by slipping the channel section of one riot shield into the channel section of the other riot shield and locking it there with the locking means.
  • the channel sections of adjacent shields are connected together from the rear of the shields and as such it is relatively easy for officers to engage and to disengage their riot shields, although it is virtually impossible for the rioters pressing on the front of the riot shields to separate them by breaking the locking means.
  • the shield member is comprised of a sheet of Lexan® 9030 FA XR.
  • the channel sections are pressed into two opposing sides of a sheet of Lexan® 9030 FA XR. It will be appreciated that other materials, such as mild steel, fibreglass, etc. may be used, provided they are suitably tough and shock resistant.
  • the shield member is not crucial, but generally it must be tall enough to afford protection from the top of a user's head to his knees and wide enough to extend beyond his shoulders on each side.
  • the shield will be rectangular in shape with the open channel shaped sections extending the length of each longest side.
  • a reinforcing plate may be secured to the back of it and this too can be formed of of Lexan® 9030 FA XR or another suitable material such as polycarbonate.
  • the reinforcing plate also gives the riot shield increased strength and resistance to projectiles and missiles.
  • the reinforcing plate is secured to the shield member by the same fastening means used to secure the handles in position.
  • the width of the reinforcing plate is such that each of two of its edges extend part way over the open channel section. In this way the edges of the reinforcing plate provide a tang against which the leading edge of the channel section of a second riot shield can brace and be locked. To assist the locking action of the edge of the reinforcing plate it may be bent over to provide a hook behind and against which the leading edge of the channel section of the second riot shield can be located.
  • the channel section is of substantially semi-circular cross-section, however other cross-sections can be envisaged, such as square, triangular and composite.
  • the shield member is formed from a plastics material which when fractured does not break into shards.
  • the shield member is resistant to attack by solvents.
  • a solvent to which it may be resistant is petrol.
  • the shield member is less than 3mm thick.
  • the shield member is between 2mm and 3mm thick.
  • the shield member is 2.5mm thick.
  • the shield member is formed from a plastics material that is capable of deforming plastically upon impact, is resistant to solvents and when fractured does not break into shards.
  • a riot shield comprising a rectangular shield member 1, a reinforcing plate 2 and two handles 3 and 4.
  • the shield member 1 is formed from a sheet of Lexan® 9030 FA XR as marketed by GE Plastics.
  • Lexan® 9030 FA XR as marketed by GE Plastics is a material that has been used in the food packaging and chocolate mould industry. It is a plastics compound comprising a mixture of polycarbonate and silicone.
  • Lexan® 9030 FA XR is slightly softer than polycarbonate and therefore the shield is less brittle. It also deforms when struck with a heavy object, which helps to absorb energy better than polycarbonate. Typically, upon receipt of a blow from, for example a brick or hammer, a shield made from Lexan® 9030 FA XR would deform plastically, whereas with a polycarbonate shield the object would either bounce off the shield or the shield would fail.
  • Shields formed from Lexan® 9030 FA XR are resistant to shatter and if such a shield were to fail it would tend to fail by tearing rather than shattering. In a shield formed from Lexan® 9030 FA XR cracks are less prone to develop from notches or abrasions than in polycarbonate shields. Furthermore, shields of Lexan® 9030 FA XR are more resistant to fuel or solvent contamination.
  • Lexan® 9030 FA XR is easier to mould in manufacture than polycarbonate. Lexan® 9030 FA XR can be transparent which makes it ideally suited to use in a riot shield where the user must be able to see beyond the riot shield without giving up the protection it affords.
  • the shield is 2.5mm thick.
  • the height and width of the shield member 1 are not crucial, but generally the shield member should be tall enough to extend from above the user's head to his knees and be wide enough to extend beyond his shoulders on each side.
  • a channel section 5, 6 of essentially semi-circular cross-section is formed on each side of the shield member 1 between the top and the bottom.
  • the open side of each channel section 5, 6 faces towards the back of the shield member 1.
  • the reinforcing plate 2 is also comprised of a sheet of the lightweight, tough, shock resistant material Lexan® 9030 FA XR. It is secured to the back of the shield member 1 by means of the same fasteners (not shown) used to secure the handles 3, 4 to the shield member 1. In fact, the reinforcing plate 2 is sandwiched between the shield member 1 and the handles 3, 4. The reinforcing plate 2 gives additional strength and rigidity to the shield member 1 about its centre and reduces torsional twisting of the shield member 1 which tends to make it difficult to hold steady.
  • the width of the reinforcing plate 2 is such that it extends part-way over the top of each channel section 5, 6 on each side of the shield member 1.
  • the handles 3 and 4 secured to the back of the shield member 1 are spaced apart so that a user can pass his forearm through one and grip the other with his hand. This allows the user to carry the riot shield easily and comfortably, whilst leaving the other arm free.
  • Figs. 2 and 3 there is shown a pair of riot shields 7 and 8 connected together along their adjacent edges.
  • the channel section 9 of riot shield 7 is engaged in the channel section 10 of riot shield 8.
  • the leading edge of channel section 9 abuts against the back of the reinforcing plate 11 of riot shield 8. If one or other of the two riot shields 7 and 8 is moved back relative to the other then the channel sections 9 and 10 will disengage from each other and the riot shields 7 and 8 will separate.
  • channel section 9 will remain in tight abutment with the back of the reinforcing plate 11, locking the channel section 9 within channel section 10 and preventing the riot shields 7 and 8 from separating except through the use of sheer brute force.
  • the riot shields embodying the present invention can also be interlocked along the top of a defensive wall comprised of riot shields.
  • the top edge of a riot shield can be locked between the channel section and the edge of the reinforcing plate of a riot shield positioned above and at right angles to it.
  • This arrangement does not provide as strong an interlock as the interlocking channel sections described hereinabove. However, it does allow the height of the defensive wall to be increased and a roof to be extended back over the officers from the defensive wall.
  • FIGs. 4(a) to 4(d) there are shown a number of alternative arrangements for interlocking adjacent riot shields together.
  • Fig. 4(a) the single locking means provided by the edge of the reinforcing plate is replaced by two spaced locking means 12, 13. These act in the same way as the edge of the reinforcing plate, but can be provided where a reinforcing plate is not present. It is envisaged that the locking means would be provided by cross members on which the handles are mounted.
  • the locking means is formed by moulding the inside edge of the channel section 14 to extend into the channel section itself.
  • a riot shield in which the locking means comprises two clips 15 located within the channel section 16.
  • the clips engage in slots 17 in the channel section of another riot shield to secure the two together. It is possible to vary the number of clips and slots, but generally speaking this arrangement is not preferred because of the expense involved in fixing the clips and forming the slots. Also it is not an especially strong arrangement.
  • Fig. 4(d) shows a locking mechanism comprising a plate 18 secured adjacent the channel section 19 of the riot shield.
  • the plate 18 may form an extension of the backing plate, if one is provided, but this is not crucial.
  • the free edge of the plate 18 is bent at an angle to the main body of the plate 18 to form a hook which projects into the channel section. When two channel sections are engaged together the leading edge of the inside channel section slips behind the hook which thus prevents it from moving laterally out of the outer channel section.
