Definitions

  • the snow on top of the roof could begin to melt.
  • the interior of the roof to be warmer than the exterior of the roof, it is also possible for the snow in direct contact with the pitched roof to melt before the snow actually within the snow body melts. In situations such as this, it is possible for the snow to slip and indeed avalanche down the roof and off on to the ground below. Obviously, the snow in itself is quite heavy and can cause serious harm to anyone underneath such snowfall. The harm to an unfortunate person under the falling snow is greatly increased when the snow on the roof has melted and refrozen several times, and is thus much more like ice than snow.
  • the roof is particularly large, the snow sliding down the pitched roof and off to the ground is hindered, and indeed in many cases stopped.
  • Other designs which instead of providing a fence at the bottom of the roof can also provide a series of stoppers over the full area of the roof, thus generally holding the snow in position on the pitched surface.
  • the single snow fence design suffers from certain drawbacks when applied to larger roofs.
  • a roof avalanche would perhaps begin with the snow towards to the apex of the roof slipping and pushing down on the snow towards the edge of the roof.
  • the shifting snow can in fact present a very large force on the snow fence, which could lead to failure of the snow fence.
  • the attachment of the snow fence to the pitched roof requires extremely large bolts or screws to be used to attach the fence to underlying wooden joists making up the roof.
  • each snow stopper is only responsible for holding back a certain amount of snow, as a snow stopper further up the roof will be responsible for part of the snow present on the roof.
  • Current designs for such snow stoppers are typically quite small, and once again do not necessarily address the problems of snow at the upper side of the snow drifts from slipping over lower portions of snow and off the roof.
  • the present disclosure is directed to an improved design for a snow stopper wherein the snow stopper is able to resist a large force from slipping snow whilst also providing multiple units over the surface of the roof to avoid build up of large avalanches leading to failure of the devices.
  • the present invention provides a snow stopper in accordance with independent ciaim 1. Further preferred embodiments are given in the dependent claims.
  • the present disclosure relates to a snow stopper which is intended to integrate with a roof, preferably a pitched rood, in order to hold any snowfall on the roof in position and avoid roof avalanches.
  • the snow stopper may be constructed from a wire portion which is intended to provide the interaction with the snow on the surface of the roof to avoid the snow from slipping, as well as a base portion which holds the snow stopper on the roof.
  • the attachment to the roof is preferably a removable attachment, however it is aiso possible to attach the snow stopper permanently to sections of the roof.
  • the base portion is preferably provided by means of an elongate strip of sheet material, wherein the sheet material is a rigid solid material possibly a plastic or metal, which is able to resist large forces acting upon it without breaking, as well as the variations in temperature on a roof.
  • the elongate strip extends in a first direction and a fixing post extending away from the plane of the elongate strip is provided at a first end of this elongate strip.
  • the fixing post may be part of the materia! making up the elongate strip which has been bent out of the plane of the elongate strip to perform the fixing post.
  • the base portion with a strengthening strip which extends along one side of the elongate strip, for at least a part of the length of the elongate strip. This acts to stop the bending of the elongate strip with excessive force from the snow,
  • the strengthening strip can also be formed as a section of the material making up the elongate strip which is bent out of the plane of the MEISSNER BOLTE M/CNI-011-PC
  • the strengthening strip and fixing post are integrally formed by bending a section of the elongate strip up out of the plane of the elongate strip to form the L cross section base portion,
  • the wire portion is attached in a permanent or removable manner to the fixing post, such that the wire will be appropriately positioned to face the snow on the roof and thus act as the snow stopper.
  • the wire portion is made up of a bent piece of wire which forms an effective surface area for facing the snow.
  • the elongate strip can itself have an approximately L-shaped shape wherein the short side may be bent up to form the fixing post, Preferably, the bend of the short side to form the fixing post is of approximately 90° to ensure that the fixing post extends perpendicularly out from the surface of the roof.
  • the strengthening strip may then extend from a second end of the elongate strip, opposite to the first end which comprises the fixing post, and tapers outward into the fixing post, such that the strengthening strip and fixing post are an integral piece of the stopper.
  • the tapering of the strengthening strip may be linear or curved up to the fixing post,
  • the strip may be bent to form a hook portion, or the like, such that this can fit behind a roof tile of the roof and hold the snow stopper on the roof,
  • the hook portion will be underneath a second roof tile which lies on top and overlaps the first roof tile, and thus the hook portion will be generally structured and shaped such that it does not interfere with the laying of the roof tiles.
  • the strengthening strip will begin at such a point so that it also does not interfere with the roof tile lying above and on top of the first roof tile to which the snow stopper is hooked or engaged.
  • the hook holds the snow stopper in place without the need of a bolt, screw or the like.
  • a fixing means is provided to attach the wire portion to the snow stopper.
  • a preferred method of attaching the wire portion to the base via the fixing post is to provide a series of slots in the fixing post which run approximately parallel with the plane of the elongate strip. The parallel slots through the fixing post allows MEISSNE BOLTE M/CNI-011-PC
  • the slots are provided in threes such that two bands lying vertically next to each other can be formed, wherein one band can be bent on one side of the fixing post, and the other band can be bent to extend from the other side of the fixing post. In this manner, several bands and channels can be provided for appropriately fixing the wire portion to the base portion.

  • the wire portion it is preferable for the wire portion to be bent such that the two ends are adjacent to each other and the wire portions next to the two ends extend for a certain distance approximately parallel with each other. In this way, the two parallel ends of the wire portion lie next to each other and could be used to interface with the slots or bands as described above on the fixing portion of the base portion.

  • the snow stopping section is an area in which the wire is bent and forms an effective surface for facing the snow and holding this to the roof.
  • the outer portions of the wire section making up the snow stopping section will be connected to the base portion only by means of the two ends of the wire which lie parallel with each other.
  • the outer portions of the snow stopping section can flex and move relative to the fixing section of the wire. This means that small vibrations of the roof with respect to the snow can be absorbed by bending and flexing of the wire portion, thus reducing the Shockwaves transmitted via the snow stopper from the roof to the snow.
  • the wire of the wire section is bent into a symmetrical pattern lying either side of the fixing portion.
  • the snow being held by the wire portion will exert an equal force of the wire either side of the fixing to the base portion, thus reducing the torque on the device.
  • the wire forming the wire portion of the snow stopper is bent in such a way that a portion of the wire generally forms an outer peripheral section or frame.
