Definitions

  • the present invention relates to anti-ligature light-fitting apparatus. More particularly, the present invention relates to anti-ligature light-fitting apparatus which prevents the attachment of means in which to hang oneself or others.
  • an anti-ligature light fitting apparatus comprising:
  • the present invention therefore relates to an anti-ligature light-fitting apparatus capable of preventing the attachment of means in which to hang oneself or others.
  • the anti-ligature light fitting apparatus may be used in a prison cell, a police holding cell or in a hospital environment, for example, dealing with patients with a mental illness.
  • the gap located between the frame and the assembly may be any suitable shape and/or size which is capable of preventing the attachment of a rope, belt, cable, shoe lace etc in which a person could hang themselves or others.
  • the gap is therefore designed to prevent the wedging, attaching, damping etc of any form of means in which hanging could occur.
  • the gap located between the frame and the assembly may be divergent towards the outer surface of the anti-ligature light fitting apparatus and is therefore too wide to attach a ligature.
  • the divergence may occur at any suitable angle such as about 20 to 90 degrees or typically about 30 to 70 degrees.
  • the widest point of the gap may therefore be proximate to, for example, a prison cell making it impossible for a prisoner to wedge, attach, clamp any form of means in which the prisoner could hang himself or others.
  • the gap may be substantially tapered such as substantially 'V'- shaped or alternatively may be substantially 'U'-shaped.
  • the gap may have a width at its widest point of about 0.5 - 2 cm.
  • the gap may also prevent dirt and dust from becoming embedded.
  • the gap may also be easily cleaned in the event that cleaning is required.
  • the anti-ligature light fitting apparatus may comprise a series of gaps which are anti-ligature.
  • gaps which are anti-ligature.
  • there may be a continuous or non-continuous anti-ligature gap around an outer perimeter formed between the frame on which the at least one light diffuser is capable of being attached and the assembly capable of attaching the frame to a ceiling or wall.
  • There may also be an anti-ligature gap extending across other panels (e.g. infill panels) used in the apparatus.
  • the anti-ligature light fitting apparatus may also comprise at least one or two light diffusing panels secured to the light diffuser frame using any suitable mechanical or adhesive means.
  • the light diffuser frame may secure the light diffusing panels in place in combination with, for example, gaskets which may be punctured with screws.
  • the assembly capable of attaching the frame to a ceiling or wall may be any suitable form of attachment or connection means such as a rail.
  • the light source used in the anti-ligature light fitting apparatus may be any suitable light emitting source such as a fluorescent tube, light bulb or lamp.
  • a method of preventing the attachment of means in which to hang oneself or others in an anti-ligature light fitting apparatus comprising:
  • the light fitting apparatus may be as defined in the first aspect.
  • the anti-ligature light fitting apparatus may be used in a prison cell, a police holding cell or in a hospital environment, for example, dealing with patients with a mental illness.
  • the present invention resides in the provision of an anti-ligature light-fitting apparatus capable of preventing the attachment of means in which to hang oneself or others.
  • Figure 6 is an upper perspective view of the light fitting apparatus 200 with infill panels 250, 252 attached.
  • the infill panels 250, 252 form a substantially planar surface with the light diffusing member 210.
  • Figure 7 is a side view of the light fitting apparatus 200.
  • the 'V'-shaped gap 236 is ringed by circle 'B' in Figure 7 and shown in expanded form in Figure 8 .
