TITLE 2014203021 03 Jun2014 “ANGLE BEAD CLIP”

FIELD OF THE INVENTION

[0001] The present invention relates to an angle bead clip.

BACKGROUND

[0002] It is known to apply a surface coating of render, plaster or other material, to wall surfaces in buildings. Generally, prior to applying the plaster or the material, an angle bead of metal may be applied along external corners where two intersecting surfaces meet, in order to enable a good finish to be achieved to the comer. The angle bead also acts to strengthen and protect the comer.

[0003] A typical angle bead is an elongate strip formed from metal and expanded into a mesh. It may comprise a rounded spine and two mounting flanges extending perpendicular to each other from the opposite sides of the spine. The mounting flanges comprise a mesh to provide both a base for overlying plaster or render and apertures for fixing means.

[0004] The angle bead is typically applied to a comer by passing nails or screws through the mesh of the mounting flanges into the underlying wall material. However, a disadvantage of this arrangement in that it is time consuming to ensure that the angle bead is level before finalising its fixing to the corner.

[0005] The present invention attempts to overcome at least in part disadvantages of previous methods of fixing angle beads to a corner.

SUMMARY OF THE INVENTION

[0006] In accordance with one aspect of the present invention there is provided a clip for fixing an angle bead onto a corner of a wall, comprising a pair of arms at a substantial right angle to one another, each arm comprising at least one finger provided with a 2 plurality of outwardly facing teeth, said teeth being resiliently flexible relative to the body. 2014203021 03 Jun2014 [0007] The finger may extend from the arm at a resilient junction.

[0008] The resilient junction may dispose the finger at an angle from the arm.

[0009] The resilient junction may be provided by bending the finger back to extend in the opposite direction to that which the respective arm extends.

[0010] The finger may comprise an upper and lower portion separated by an elongated recess.

[0011] The pair of arms comprising at least one finger each, may form opposing pairs of fingers.

[0012] The clip may further comprise a means for attachment to a surface.

[0013] The means for attachment may comprise an aperture for receiving a fixing device.

[0014] The means for attachment may comprise protrusions for punching into the wall.

[0015] The resilient junction may be provided by bending the finger back to extend in the opposite direction to that which the arm extends.

[0016] The each at least one finger of the clip of the present invention may be punched, around a majority of its periphery, out from an arm.

[0017] According to one embodiment, the clip of the present invention may be made from steel. Preferably, the clip may be made from galvanised or stainless steel. 3 [0018] According to another embodiment of the present invention, the clip may be made from plastic. 2014203021 03 Jun2014 [0019] In accordance with one aspect of the present invention there is provided a method for attaching an angle bead to a wall comer comprising the use of a clip comprising body having at least one finger extending from a resilient junction, the finger provided with a plurality of outwardly facing teeth.

DESCRIPTION OF PREFERRED EMBODIMENTS

[0021 ] hi Figures 1 and 2 of the accompanying drawings there is shown an angle bead clip 10 in accordance with a first embodiment of the present invention.

[0022] The angle bead clip 10 comprises a body 12 which is formed of a single piece of sheet material. The body 12 is formed into a pair of flat arms 14 which extend away from a substantially right angled bend 16.

[0023] Each arm 14 is formed at its outer end with an integral deformed respective finger 18. The fingers 18 are produced by bending back an outer end portion of the corresponding arms 14 in a known manner, towards the obtuse side of the right angled bend 16. A resilient junction 19 is formed with the respective arm 14.

[0024] Each finger 18 is provided with an upper and lower portion separated by an elongated recess 22. The fingers 18 initially taper, narrowing toward the recess 22 in a direction away from the junction 19. Distal of the tapered regions, the upper and lower portions of the fingers 18 are of uniform width and are provided with teeth 21 arranged in respective rows. The teeth 21 are integrally formed with the respective portion of a finger 18 and extend outwardly away from the adjacent arm 14. The teeth 21 are preferably cut so as to angle away from the outer end of the corresponding finger 18 as shown in Figure 2.

[0025] The angle bead clip 10 may be fixed to a comer 24 of a wall 26 as shown in Figure 3. This may be achieved through adhesion using an adhesive on a rear surface 28 (see Figure 1) of the clip 10 remote from the fingers 18. Alternatively, the arms 14 may 5 be attached to the wall 26 by fixing means including, but not limited to, screws, nails, staples and protrusions from the arms 14. 2014203021 03 Jun2014 [0026] Essentially, each arm 14 is affixed to a respective wall 26 on opposite sides of the comer 24. Thus, the bend 16 is located co-axially at the comer 24 with the teeth 21 facing outwardly. An angle bead 30 shown in Figure 2 can be readily affixed to the clip 10 by engagement of the teeth 21 with the angle bead 30 as shown in Figure 2.

[0027] In the embodiment shown in Figures 4 to 6, like reference numerals are used to denote like parts to those found in Figures 1 to 3. In this embodiment an angle bead clip 40 comprises a body 42 which is formed of a single piece of sheet material. The body 42 is formed with a pair of flat arms 14 extending from a bend 16 substantially at right angles as in Figures 1 and 3. Further, each arm 14 is provided with fingers 18 as in Figures 1 to 3 including outwardly facing teeth 21.

[0028] However, in this case the fingers 18 are formed by being punched out from the arms 14 so that whilst the fingers 18 remain attached to the arms 14 at junctions 44 they extend outwardly from cut away apertures 46 in the arms 14. The angle bead clip 40 further comprises additional apertures 48 for receiving fixing means such as screws or nails.

[0029] Again, in the embodiment shown in Figures 7 to 9, like reference numerals are used to denote like parts to those found in previous Figures. In this embodiment, an angle bead clip 50 comprises a body 52 which is formed of a single piece of sheet material. The body 52 is formed with a pair of flat arms 14 extending from a bend 16 substantially at right angles as in previous Figures. Further, each arm 14 is provided with fingers 18 as in Figures 1 to 3 including outwardly facing teeth 21.

[0030] In this embodiment, the fingers 18 are formed by bending back respective upper and lower portions of the corresponding arms 14 forming junctions 59. The bend is towards the obtuse side of the right angled bend 16 in a similar fashion to angle bead clip 6 10 of Figure 1. However, the portions of the arms 14 bent to produce the fingers 18 are not at the end of the arms 14 but somewhat distal to the end. A fixing tab 56 forms the distal end of each arm 14. The additional apertures 48 are located at the fixing tabs 56. 2014203021 03 Jun2014 [0031] Again, in the embodiment shown in Figures 10 to 12, like reference numerals are used to denote like parts to those found in previous Figures. In this embodiment, an angle bead clip 60 comprises a body 62 which is also formed of a single piece of sheet material. The body 62 is formed with a pair of flat arms 14 extending from a bend 16 substantially at right angles as in previous Figures. Further, each arm 14 is provided with fingers 68.

[0032] The fingers 68 of angle bead clip 60 comprise bent portions of the arms 14 at junctions 64 in a similar fashion to the fingers 18 of angle bead clip 40. However, the fingers 68 are not punched out from the arms 14 but rather are cut from the upper and lower edges of the arms 14 leaving a narrower arm 14 between the bend 16 and the junctions 64 and a complimentary shaped recess 22 between upper and lower portions of the fingers 68. The fingers 68 also comprise outwardly facing teeth 21.

[0033] The angle bead clip 60, at the end of the arms 14 distal to the bend 16, further comprises protrusions 63 extending from the rear surface 28 of the arms 14. The protrusions 63 may be provided as spikes.

[0034] In use, the angle bead clip 10, 40, 50, 60 is affixed to a comer 24 of a wall 26 where an angle bead 30 is required as shown in Figures 3, 6, 9 and 12. The angle bead clip 10, 40, 50, 60 may be affixed through adhesion using an adhesive between the rear surface 28 of the clip 10, 40, 50, 60 or the arms 14 may be attached to the wall 26 by fixing means including, but not limited to, screws and nails through the apertures 48, staples or protrusions 63 from the arms 14 punching into the wall 26.

[0035] Essentially, each arm 14 is affixed to a respective wall 26 on opposite sides of the comers 24. Thus, the bend 16 is located co-axially at the comer 24 with the teeth 21 7 facing outwardly. An angle bead 30 can be readily affixed to the clips 10, 40, 50, 60 by engagement of the teeth 21 with the mesh of the angle bead 30. 2014203021 03 Jun2014 [0036] This is achieved by pressing the bead 30 onto the teeth 21 against the resilience of the junctions 19,44, 59, 64. The engagement of clip 10,40, 50, 60 with angle bead 30 is maintained after pressure ceases to be applied so that the bead 30 is attached to the angle bead clip 10, 40, 50, 60. Thus, as the fingers 18, 68 are flexed inwardly about the junctions 19, 44, 59, 64, the teeth 21 engage with the bead 30.

[0037] The orientation of the angle bead 30 may be adjusted, to ensure that it is level, by varying the teeth 21 with which it is engaged. That is, it is normally desirable for the angle bead to be exactly vertical. As such, the teeth 21 with which the angle bead 30 is engaged may be varied. For example, if it is desired for the angle bead to be mounted closer to the wall 26, the angle bead 30 may be engaged with teeth 21 closer to the junctions 19, 44, 59, 64. For finer adjustments, variation of the engagement of the angle bead 30 with teeth 21 may be performed on one side of the corner 24 only. This provides the advantage, over traditional means of fixing an angle bead 30, of significantly reducing the time taken to fix an angle bead 30 to the comer 24 of a wall 26 and ensuring it is straight.

[0038] If it is desired, the angle bead 30 may be removed through utilisation of a known tool such as a screwdriver. The screwdriver may be inserted through an aperture of the angle bead 30. The fingers 18,68 and therefore teeth 21 of any embodiment angle bead clip 10, 40, 50, 60 may be pushed back away from the angle bead 30 by the tool so that their grip on the angle bead 30 is released. Alternatively, the clip 10,40, 50,60 may be accessed by a tool from the ends distal the comer 24 of the wall 26.

[0039] Other embodiment angle bead clips 10, 40, 50, 60 are also contemplated in accordance with the present invention. For instance, the aforementioned teeth 21 may, instead of being provided as spikes, comprise corrugations perpendicular to the length of the fingers 18 on which they are located. Additionally, while the examples herewith 8 show the use of the clips 10, 40, 50, 60 for fixing an angle bead 30 to a wall 26, other suitable uses for the clips 10, 40, 50, 60 such as fixing protective covers to a wall corner or fixing aesthetic covers to a vehicle or building comer, for example, are envisioned. Rather than the teeth 21 engaging with apertures in these other covers, the cover could be provided with corresponding engagement points on its back surface for the teeth 21 to engage with. 2014203021 03 Jun2014 [0040] Other modifications and variations as would be apparent to a skilled addressee are deemed to be within the scope of the present invention. 9
