Abstract

ABSTRACT OF THE DISCLOSURE

A locking structure comprising a channel and a bracket.
The channel has a pair of lips defining an elongated mouth.
The bracket is L-shaped having a horizontal limb and a vertical limb extending downwardly from one end of the horizontal limb.
The bracket has a neck the lower end of which merges with said vertical limb. The neck extends obliquely upwardly from said vertical limb and has a locking formation at its free end.
The locking formation is wider than the neck and projects laterally on each side of the neck. The neck can pass through the mouth. When the bracket is so positioned with the neck passing through the mouth, the laterally projecting parts of the locking formation engage one face of each lip. The external surface of the vertical limb engages the other face of each lip.
Said one face of each lip is formed with deformable serrations which extend in the direction of elongation of the mouth.

Description

1~8l~4 !3'~

SPECIFICATION:
This invention relates to a lockïng device which provides a positive metal to metal lock.
It is common in locking de~ices using a metal to metal lock to be provided with a secondary lock in the form of a nut and bolt and the like to hold the lock in the engaged position and to reduce pro~lems caused through wear or minimum tolerance factors. I have found that these disadvantages are overcome by providing serrations on the rearward facing surfaces of the :
lips of the support member. I have further found that crushing ~during the locking action is restricted to the said serrations :
and prevents bruising of the outer visible faces of the lips of ~the support device..
According to the present inven-tion there is provided a locking structure comprising a b.racket and an ele~ent on which the bracket can be mounted, the element including a pair of laterally spaced lips which define a mouth therebetween, and the bracket having a main portion and a neck protruding from the main portion, the dimensions of the neck being such that it can :
pass through said mouth, there being a locking formation carried :
by the free end of. the neck and extending laterally~of the neck on each side thereof, the dimensions of the locking -formation, transversely of the neck, being greater than the width of said mouth and the locking formation being intended to abu-t one face ~ of each lip when the neck is in the position in which it passes through the mouth,.said main portion having a surface which, . .
when said neck is passed through said mouth and said locking formation is brought into abutting relationship with sald one face of each lip, abuts the other face of each lip, said one face of each lip being formed with longitudinally extending serrations the peaks of which are engaged by said locking formation. ~ :

In a ~urther embodiment the invention provides a locking structure which comprises an element having a web, flanges extend-ing from opposite ends of the web, a pair of laterally spaced, oppositely directed lips extending from the flanges which define a mouth therebetween with each of the lips having an inner face formed with longitudinally extending serrations and having an outer face, and a bracket having a main portion, and a neck pro~
truding from the main portion with one end coupled to the main ~.
portion and a free end remote from the main portion with the neck . -.:
being dimensioned so it may pass through the mouth. A locking formation is mounted on the free end of the neck and extends laterally from each side of the neck wi-th the dimensions of the .
locking formation in a direction transverse of the neck being greater than the width of the mouth and with the locking Eormation having an abuttiny ~ace adapted to abu-t the serrations on the ~ . :
lnn~r ~ace~ o~ the lips. Thus when the neck ls located in the mouth and the bracket is located in position relative to ~he element, a surface of the main portion is brought into abutting relationship with the outer face of the lips and the abutting ::
face of the locking formation is brought in-to abutting relation~
ship with the serrations on the inner faces of the lips.
In yet a further embodiment the invention contemplates a locking structure which comprises an element having a pair of laterally spaced, oppositely directed lips which define a mouth therebetween with the lips having inner and outer ~aces, and a bracket which has a main portion with a surface adapted to abut the outer faces of the lips, and a neck protruding from the main portion with one end coupled to the main portion and a free end remote from the main portion with the neck beiny dimension so it . 30 ma~ pass through the mouth. A locking formation is mounted on . the free end of the neck and extends laterally from each side of the neck with the dimensions of the locking formation in a direc--. tion transverse of the neck being greater than the width of the .. ~

mouth, and with the locking formation having an abutting face adapted to abut the inner faces of the lips. The thickness of the lips between the inner and outer faces is greater than the horizontal spacing between a vertical plane containin~ the surface of the main portion and a vertical plane containing the abutting ;
face of the locking formation, whereby the bracket and the element .: .
may be fixed relative to each other by entrapping the lips between the main portion surface and the locking formation abutting face.
For a better understanding of the present invention, .~
10 and to show how the same may be carried into effect, reference ~ -will now be made, by way of example, to the accompanying drawings in which:
Figure 1 is a side elevation of a bracket, Figure 2 is a top plan view of the bracket of Figure 1, Figure 3 is a rear elevation oE the bracket of Figure 1, Figure ~ is a pictorial view, to a large.r scale, o:E a channel, Figure 5 is a side elevation, partly in sectioli, showing the bracket mounted on the channel, Figure 6 is a top plan view taken in the direction of arrow VI in Figure 5, and Figure 7 illustrates the relationship be-tween the . bracket and channel when it is desired to move the bracket rela-tive to the channel.
Referring firstly to Figures 1 to 3, ~he bracket 10 illustrated includes a horizontal portion 12 on the upper surface of which rests a shelf (not shown) or other element to be support-ed by the bracket. The horizontal portion 12 protrudes from a : -vertical portion generally indicated at 14, there being a ~ .
30 strengthening web 16 in the angle between these two portions. .~
..
~: The web 16, in plan view, is wider where it joins the portion 12 than is the portion 12 itsel (see Figure 2) and extends ~.

over approximately half the length of the portion 12. The portion ~ .
14 is also wider than the portion 12 and is equal in width to the ~.
maximum width of the web 16. ... .:
A supporting block 18 protrudes rearwardly from the .
rear face of the portion 14. The block 18, in both height and width, is smaller than the rear face 20 and is positioned towards .
the top of this face.
A neck 22 of round cross section protrudes upwardly and rearwardly from the block 18, the diameter of the neck being .~ :
. 10 equal to the width of the block. The longitudinal axis x of the neck (Figure 1) is not at right angles to the upper surface .
of the portion 12 but lies at an angle of approximately 45 :
degrees with respect to it. ::
A locking formation 24 is provided at the upper end o~ the neck 22. ~he width of this formation (see Figure 2) is c3reater than the diameter of the neck and is sl.iqllt:ly :Less than the width of the face 20. The formation 24 includes an integral cross bar 26 and supporting gusset 28, the gusset strengthening the cross bar to prevent fracturing thereof in use. The gusset is, in the illustrated embodiment, shown as being approximately semi-circular in plan view.
Turning now to Figure 4, the channel illustrated is . of constant cross-sectional shape and indef.inite lengtll. Th.is channel comprises a web 30 and two flanges 32, the web and flanges being at right angles to one another. Lips 3~, parallel to the web 30, extend towards one another from the free edges : :
-~ of the flanges 32. The lips 34 together define a mouth 36 and each is formed, on the surface thereof which faces the web 30, : .
with longitudinally extending serrations 38. The serrations are of triangular cross-section thereby to provide readily deformable pointed peaks. Symmetrical serrations as illustrated .:~

are preferred but saw-tooth serrations can be used provided they -4- :

~3 . :.
~ : . .. . ' ~L~889L~

have the required deformahle peak~.
To mount the bracket on the channel, the formation 24 is entered into the cavity bounded by the web, flanges and lips of the channel. This can be achieved in two ways. Firstly, with the outer end of the bracket tilted upwardly as shown in Figure 7, the formation 24 can be entered into the channel from one end thereof. While the width of the formation 24 exceeds the dimen-sion of the mouth 36 between the lips 34, the diameter of the neck is less than this dimension. Thus, while the bracket is tilted to maintain the formation 24 away from the serra-tions 38, the bracket can be shifted freely with respect to the channel.
Secondly, the bracket may be turned onto its side and presented to the vertically extending channel with the axis oE -the neck horlzon-tal, i.e. with the bracket at right arl~les ~o thc position shown in r~'igure 7. The gusse~ 2~ :initially ellters ~he mouth 36 and then, by pivoting -the bracket abou-t a vertical axis extending in the direction of elongation of the mouth 36, the entire formation 24 can be swung into the channel with the neck 32 passing through the mouth 36. The bracket is then rotated about ZO a horizontal axis intersecting said vertical axis and passing centrally through the mouth 36 and web 30 until it reaches the positlon oE Figure 7 whereafter its outer end can be lowered to the position in Figure 5.
When the bracket is in the position shown in Figure 5, the peaks of the serrations are deformed by pressure exerted - ~-thereon by the formation 24 so as positively to lock the bracket to the channel. As the force on the outer end of the bracket increases, the peaks are deformed still further due to the increase in the moment thrusting the formation 24 against the . . .;: .

~ -5-8~
peaks. To ensure that the peaks are deformed, the thickness of each lip 34 measured from the peaks of its serrations to the outer face thereof is greater than the horizontal spacing between a vertical plane containing the surface 20 and a vertical plane containing -the face of the cross bar 26 remote from the gusset 28.
The channel may be fixed to a wall or may form an upright of a furniture unit. In both cases it mounts one or more brackets 10 on which shelves or other elements are supported.
In another embodiment, the channel forms part of a free standing pole having a central core with flanges radiating therefrom.
Oppositely directed lips are provided at the outer, free end of each flange thereby to provide a circumferen~;al array of mouths in which bracket~ can be entered. In yet another embodiment, the channel can be do~lbLe-sided so as to support a bracket pro-truding in opposite directions thererom.
The ability to use various shape5 of channel stems from the fact that only the lips are involved in the locking action.
Thus provided suitable serrated lips are incorporated, -the remainder of the channel can have any shape tha-t is required.
