Definitions

  • the present invention relates to collapsible posts.
  • the invention relates to collapsible lamp posts arranged to allow the luminaire to be lowered so as to enable maintenance of the luminaire and associated components.
  • Folding lamp posts are known that incorporate a hinge at a lower or middle region of the post in order to allow an upper portion of the post to be lower towards ground.
  • GB91 1784 discloses a street lighting column having an upper portion connected to a lower portion by means of a hinge provided on an outer surface of the column.
  • the hinge is provided approximately midway along the column.
  • the upper portion is arranged to pivot about the hinge to allow access to a lantern at the top of the column by an operative standing on the ground.
  • Means are provided in the base of the column for lowering the upper portion of the column towards the ground.
  • a tension spring is provided that assists in returning the column to a normal upright configuration.
  • GB9681 13 discloses a street lighting column again having a hinge provided on an outer surface of the column, the hinge being located in a base portion of the column. The hinge is arranged to allow the column to pivot towards the ground for maintenance of a lantern at the top of the column.
  • a removable key is provided that may be moved between different columns, the key having a spring that assists in returning the column to its normal upright condition after the column has been lowered.
  • JP2000228105 discloses a collapsible street lamp pole also having a hinge provided on an outer surface of the column, the hinge being located approximately midway along a length of the column. An upper portion of the pole can thereby be lowered towards the ground to allow maintenance of a lamp at an upper end of the pole.
  • a tiltable column comprising: a first post member; a second post member; and a hinge assembly, the hinge assembly being arranged to hingedly connect the first post member and the second post member, wherein the hinge assembly is so sized and configured that no part thereof extends outside an envelope defined by outer surface portions of the first and second post members local to the hinge assembly.
  • the invention has the advantage that the hinge assembly is less exposed to the external environment of the column.
  • the hinge assembly is less prone to degradation, for example due to rain, ice, dust, and other environmental hazards.
  • the hinge assembly is also less vulnerable to unauthorised tampering and vandalism.
  • the hinge assembly is also less likely to cause injury to persons or property moving past the column, since it does not protrude beyond an envelope defined by outer surface portions of the first and second post members local to the hinge assembly.
  • the column comprises biasing means arranged to urge the second post member to the normal upright configuration.
  • This feature has the advantage that movement of the second post member by an operative between a tilted orientation and a normal upright orientation is made more easy when biasing means is provided.
  • the biasing means comprises a resilient member.
  • the resilient member is arranged to be under tension when the second post member is in a tilted orientation wherein in the tilted orientation the second post member is tilted away from the normal upright orientation.
  • This feature has the advantage that failure of the resilient member when the second post member is tilted relative to a normal upright orientation tends to result in the resilient member collapsing on itself.
  • failure of the resilient member tends to result in the resilient member becoming displaced with not inconsiderable force in a downward direction, away from the hinge assembly. This can result in damage to the column, and in particular to components of the column located below the hinge assembly. In the case of a collapsible column having a luminaire, this can result in damage to electrical service apparatus associated with the luminaire that is located below the hinge assembly.
  • the resilient member is arranged to be not subject to substantially any compression or tension forces when the second post member is in the normal upright orientation.
  • the resilient member is substantially 'at rest' when the second post member is in the normal upright orientation.
  • This feature has the advantage that deterioration of a structural integrity of the resilient member is less likely compared with the case where the resilient member is maintained under tension or compression. Stresses are only generated when the second post member is tilted from the normal upright orientation of the second post member.
  • the biasing means may comprise a counterweight arrangement.
  • the column comprises a releasable locking member, the locking member being movable between a locked configuration and a released configuration, in the locked configuration the locking member being arranged to maintain the second post member in the normal upright orientation, in the unlocked configuration the locking member being arranged to allow the second post member to tilt with respect to the first post member by means of the hinge assembly.
  • the feature of a locking member has the advantage that inadvertent tilt of the second post member with respect to the first post member may be prevented when the second post member is the normal upright orientation.
  • the locking member comprises a collar or sleeve member arranged to be movable with respect to the first and second post members.
  • a collar or sleeve arrangement allows a strong, stable locking member to be provided. That is, a locking arrangement may be provided by means of a collar or sleeve arrangement that is capable of resisting substantial tilting forces on the second post member. Preferably the collar or sleeve member is arranged to be slidable with respect to the first and second post members.
  • the collar or sleeve member is arranged to be substantially coaxial with at least one of the first and second post elements.
  • the hinge assembly comprises a first hinge element and a second hinge element, the said elements being hingedly attached, and the first hinge element being joined to the first post member and the second hinge element being joined to the second post member.
  • the resilient member is connected between the first hinge element and the second post member.
  • This feature has the advantage that the resilient member may be arranged not to protrude into a region of the collapsible column below the hinge assembly. This has the advantage that an internal volume of the collapsible column below the hinge assembly that is available for storage of ancillary equipment such as electrical service apparatus is not reduced by the presence of the resilient member.
  • collapsible column has a luminaire at the top of the second post member
  • space within the column below the hinge assembly is typically used to site electrical apparatus that is arranged to supply electric power to the luminaire. This space is not reduced by the presence of a resilient member arranged according to some embodiments of the invention.
  • At least one of the lower hinge assembly and the second hinge assembly is arranged to be joined to a respective post member by means of at least one selected from amongst an adhesive, a mechanical fixing element, a compression or interference fit, or any other suitable fixing means.
  • This feature has the advantage that assembly of the collapsible post may be conveniently performed at the site of installation of the post. This is because a requirement to perform a complex machining operation on a post member and requiring workshop equipment is avoided, according to some embodiments of the invention.
  • At least one of the first and second hinge elements is arranged to be formed integrally with the first or second post members, respectively.
  • This feature has the advantage that fixing means are not required.
  • An amount of tension in the spring member may be adjusted by means of an extender member.
  • the extender member comprises a screw member, the post being arranged whereby an amount by which the spring member is extended when the second post member is in the tilted orientation may be adjusted by rotation of the screw member.
  • Access to the screw member may require that the locking member be moved to an unlocked condition before the screw member can be adjusted.
  • a method of making a collapsible column comprising the steps of: providing a column having first and second post members; providing a hinge assembly comprising first and second hinge elements hingedly joined together; attaching the first hinge element to the first post member and attaching the second hinge element to the second post member, wherein the hinge assembly is so sized and configured that no part thereof extends outside an envelope defined by outer surface portions of the first and second post members local to the hinge assembly.
  • a modified column comprising the division of the column into first and second post members and a hinge assembly inserted between the first and second post members and joining the first and second post members together, the hinge assembly being so sized and configured that no part thereof extends outside an envelope defined by outer surface portions of the first and second post members local to the hinge assembly.
  • a tiltable column comprising: a first post member; a second post member; a hinge assembly, the hinge assembly being arranged to hingedly connect the first post member and the second post member; and a releasable locking member, the locking member being movable between a locked configuration and a released configuration, in the locked configuration the locking member being arranged to maintain the second post member in a normal upright configuration, in the unlocked configuration the locking member being arranged to allow the second post member to tilt with respect to the first post member by means of the hinge assembly, wherein the locking member comprises a collar or sleeve arranged to be movable with respect to the first and second post members.
  • a column according to some embodiments of the invention is more resistant to inadvertent folding of the second post member with respect to the first post member due to tampering, vandalism or impact with an object such as a motor vehicle.
  • a method of making a collapsible column comprising the steps of: providing a column; dividing the column to form a first post member and a second post member; connecting the first post member to the second post member by means of a hinge assembly; and providing the column with a releasable locking member, the locking member being movable between a locked configuration and a released configuration, in the locked configuration the locking member being arranged to maintain the second post member in a normal upright configuration, in the unlocked configuration the locking member being arranged to allow the second post member to tilt with respect to the first post member by means of the hinge assembly, the locking member comprising a collar or sleeve arranged to be movable with respect to the first and second post members.
  • a converted column the conversion being that the street column has been divided into a first post member and a second post member, the second post member being hingedly connected to the first post member by means of a hinge assembly, the column further comprising a releasable locking member, the locking member being movable between a locked configuration and a released configuration, in the locked configuration the locking member being arranged to maintain the second post member in a normal upright configuration, in the unlocked configuration the locking member being arranged to allow the second post member to tilt with respect to the first post member by means of the hinge assembly, and whereby the locking member comprises a collar or sleeve arranged to be movable with respect to the first and second post members.
  • a column in combination with a jig, the jig being configured to support a second post member when the column has been divided into a first post member and a second post member, the jig being configured to raise the second post member thereby to allow a hinge assembly to be fitted, the hinge assembly being so sized and configured that no part thereof extends outside an envelope defined by outer surface portions of the first and second post members local to the hinge assembly.
  • a tiltable column comprising first and second post members, the hinge assembly comprising a first hinge element including a first joining region configured to be connected at a first end of the first column portion and a first hinge formation arranged distally with respect to the joining portion, and a second hinge element including a second joining region configured to be connected at an end of the second column portion and a second hinge formation arranged distally with respect to the joining region and to cooperate with the first hinge formation to form a hinge, the hinge assembly being so sized and configured that no part thereof extends outside an envelope defined by outer surface portions of the first and second post members local to the hinge assembly.
  • Embodiments of the present invention have the advantage that the hinge assembly may be positioned with respect to the column at a location independently of the location of an electrical access panel. According to some prior art columns, access to electrical equipment in a lower portion of the column is provided by tilting of the column to expose the electrical equipment.
  • the hinge assembly may be provided at substantially any location along a length of the column, independently of the location of an electrical access panel. Access to the electrical components behind an access panel is therefore independent of the orientation of the upper post member with respect to the lower post member, in some embodiments of the invention.
