Definitions

  • This invention relates to a bracket, and more specifically to a bracket that is to be fastened to a support surface, with a supporting section protruding from the fixed surface for supporting a load.
  • brackets usually have a securing section used to secure the bracket to a wall or other support surface, and the supporting section extends away from the securing section.
  • Brackets are typically upright and may be a wall, with the supporting section of the bracket extending away from the wall. This can easily be achieved where substantial members are used, however, it is usually desired to provide brackets at relatively low cost, and inexpensive inherently weaker materials are often used, for example flat sheet metal.
  • the supporting section of brackets are usually braced against the securing section to adequately support the load instead of relying upon the natural rigidity of the material from which the bracket is made.
  • the bracing may be in the form of a strut extending between the securing section and the support section, or for those brackets designed for lesser loads the bracing may be in the form of a profiled, otherwise flat, metal member. Often, especially with the latter, the securing section is beneath the load so that added support is given to the load by the securing section.
  • brackets as good a structural rigidity as is possible is sought for the types of material from which the bracket is made. Where greater structural strength is required materials are varied and often members tubular in cross section may be used to make up the bracket still using relatively thin metal thicknesses.
  • brackets including those of tubular construction are designed to support loads at one position relative to the support surface and should the support surface deviate from the norm, for example by the angle being significantly different to vertical, purpose built brackets generally need to be provided. Alternatively the angle between the support surface and the securing section may need to be altered, for example by insertion of wedges. The use of such measures however is a little awkward, and requires the provision of relatively accurately formed wedges. It is desirable therefore to have a bracket that has a supporting section that can be supported from a support surface at a range of different angles relative to a securing section. The difficulty is to provide the variation in angle, whilst maintaining sufficient rigidity and strength of the supporting section of the bracket.
  • bracket of relatively simple construction, and preferably of unitary construction so that minimal working is required to construct the bracket to minimise cost. It is therefore not desirable to have moving parts joined to rigid bracket members.
  • It is an object of this invention is to provide a bracket that obviates or minimises at least one of the aforementioned problems in a simple yet effective way, or at least provides the public with a useful choice.
  • the invention could be said to reside in a bracket for fastening to a supporting surface, said bracket formed of metal tubing and said bracket comprising a supporting section and a securing section the supporting section including a first portion bearing against the supporting surface when in use, and a second portion extending away from the first portion to provide support for a load, a hinge between the supporting section and the securing section, whereby to permit hinging of the securing section in relation to the supporting section.
  • the hinge is formed by deforming the tubing so as to take on a flat cross- sectional aspect.
  • a hinge is therefore formed at an interface between the flat section and the supporting section.
  • this arrangement permits the bracket to be fixed to a support surface, and the supporting section pivoted relative to the securing section so that the first portion of the support section rests against the support surface.
  • the bracket is set up so that the support section is below the securing section the first portion bears against the support surface, to prevent the hinge from over extending and supports the load.
  • the first portion need not extend downwardly a great deal, but just sufficient to bear against the support surface.
  • Preferably all of the securing section is deformed so as to be flat. This configuration facilitates manufacture, and facilitates the securing to the support surface, because holes that might be drilled through the securing section do not need to go through two spaced apart layers and thus the bracket can be more accurately placed in position.
  • the tubing may take up a number of configurations.
  • the tubing in a preferred form is closed in cross section, and may for example, be square or rectangular, rounded, or circular in cross section.
  • the tubing may also be open in cross-section, for example it may be made of a C section material.
  • tubing is formed rounded, because this facilitates manufacture. Deforming of the tube is a great deal easier with a round tubular section.
  • the support section of the bracket may be of a number of different configurations.
  • the support section may be L-shaped, the first portion extending downwardly, and a second portion extending outwardly normal to the first portion.
  • the support section includes a U shaped hook. The second form is more convenient to manufacture, and is therefore preferred.
  • the invention might also be said to reside in a bracket of unitary tubular construction from a length of elongate material comprising a supporting section a securing section and, a hinge between the supporting section and the securing section, whereby to permit hinging of the securing section in relation to the supporting section.
  • the invention might be said to reside in a method of manufacturing a bracket from a single piece of elongate metal tubing comprising the steps of bending a first part of the tubing proximal to a first end into a support section shaped to support a load, and flattening a second part of the tubing proximal to a second end of the tubing to form a hinge at an interface between the flattened second part and the first part but spaced apart from the second end, a securing section defined between the hinge and the second end, whereby to permit hinging of the securing section relative to the supporting section.
  • Figure 1 is a perspective view of the illustrated embodiment
  • Figure 2 is a side plan view showing the hinging action, the bracket being supported on a tubular support and the support portion of the bracket being shown in a first position in broken outline, and in a second position in unbroken line,
  • Figure 3 is a cross sectional view showing the unitary tubular construction of the bracket
  • Figure 4 is a perspective view from the inside of a wall, showing the bracket fitted to a rail, and to sheeting, and
  • Figure 5 is a view from above showing two opposed brackets fitted to a corrugated iron sheet.
  • the illustrated embodiment is a bracket, comprising a support section (1) and a securing section (2).
  • the bracket is formed from a single piece of tubing having a circular cross- section.
  • a hinge (3) is formed in the bracket between the support section and the securing section, by flattening the tube. In the illustration the hinge is achieved by flattening the entire securing section (2) so that the hinge is provided at an internal end of the securing section.
  • the support section comprises a first portion (4), which bears against the support surface when in place, and a second portion (5) which has a generally U shaped configuration.
  • the load is placed within the U shaped, second portion of the supporting section.
  • the flattened securing section is formed so that it is generally in line with a back (30) of the supporting section, and is thus offset from the centre line. This configuration maintains the hinge in line with the back of the supporting section and that portion of the supporting section that bears against the support surface when in place.
  • the illustrated bracket is supplied generally in the configuration shown in Figure 1 ; the securing section being in line with the first portion of the supporting section.
  • the securing section may be fastened to a rail (13) the support section extends away from the rail as best seen in Figure 2.
  • the securing section has two holes (6, 7) through which fasteners, such as self tapping screws (20, 21 ) can be passed to secure the securing section to the rail.
  • the advantage of this form of the securing section over a section where the securing section is not flat is the ease with which fasteners can pass through the securing section which facilitates accurate placement of the bracket and inhibits the capacity of the bracket to work loose should the otherwise tubular securing portion deform under the strain of a load.
  • the supporting section can be moved down into position by hand, until the first portion (4) of the supporting section bears against the rail.
  • the rail therefore acts as a means to prevent over-extension of the supporting section and acts as a structural support for load on the bracket. It may be desired to supply the bracket such that the securing section is already angled relative to the support section, for example at right angles, and then the hinge (3) will permit fine adjustment of the position of the support section.
  • the bracket has a number of different uses, for example, it may be fastened directly to a wall as shown in (8) in Figure 3.
  • the bracket need not be used such that the supporting portion (5) depends downwardly from the securing portion (4), it may extend to one side, as shown in Figure 4. wherein two oppositely positioned brackets (9, 10) are each fastened to a fence (11) made of corrugated iron.
  • the advantage of the hinge being able to take on a range of angles can clearly be appreciated.
  • the tubing from which the illustrated embodiment is made is steel, with a diameter of 19mm, with a wall thickness of 1mm. It is found that this thickness of tubing leads to a bracket with sufficient strength in the bracket, and still enables the hinge to be operated manually, by a person simply bending the supporting section downwardly by hand to put it into position. It can be appreciated that the forming of the hinge does not reduce the thickness of the wall appreciably below its original 1mm thickness. Other embodiments may well include reducing the thickness of the wall.
  • tubing is cut into a length, a first end is bent into the U shape in a tube bender, which may either be a manually operated tube bender or an automatic apparatus.
  • the U shape being generally arcuate.
  • a great advantage of the U shape is that it can be relatively easily formed, from thin tubing, and at the same time is less prone to becoming deformed under load when fitted than for example a L shaped bracket.
  • the opposite end is deformed flat by a clamp, and holes (6, 7) are drilled.
  • the opposite end is flattened and holes are stamped out in one step in a press.
  • the open end (12) of the bracket may be plugged such as by a plastic plug.
  • the bracket is preferably finished in a suitable manner such as by powder coating.

Abstract

Support formé d'un tuyau métallique, comprenant une section d'appui (1) et une section d'arrêt (2), avec une charnière (3) entre les deux sections. La section d'appui (1) comprend une première partie (4) qui, en cours d'utilisation, est placée vers le bas par rapport à la section d'arrêt, de façon à s'appuyer contre la surface sur laquelle la charnière est attachée. La seconde partie (5) de la section d'appui est relevée par rapport à la première partie de façon à pouvoir soutenir une charge. Au niveau de la charnière (3), le tube est déformé de manière à lui donner un aspect plat. Grâce à cette section plate, la surface de jointure entre la section d'arrêt et la section d'appui est limitée, ce qui permet de fixer aisément le support sur des surfaces d'inclinaisons différentes.
