DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to the figures, particularly figures Ia to Ic; there is shown a support device 10'for supporting an article (such as, for example, a picture frame, not shown) on a structure, for example a wall 12. The support device 10 has an elongate body 14 having a support head portion 16 located at one end thereof.
The support head portion 16 includes a head 18 and a shoulder flange 20 which are separated by a neck 22. .
As will be described, the head 18 and /or neck 22 are arranged to engage the article while the shoulder flange 20 has a surface 20a for engaging a corresponding surface of the structure.
The elongate body 14 has an elongate shank portion 24 for anchoring the support device at a target site on the structure. The elongate shank portion is, in this example, screw threaded with a proximal end 24a adjacent the shoulder flange 20 and a distal end 24b, and the shank portion.24 decreases in cross-section from the proximal end to the distal end 24b.
Preferably, the elongate shank portion 24 has a helical thread 26 extending along its surface. The thread 26 has two surfaces 26a, 26b extending along its length which converge toward one another to form an edge 26c. The height of the thread, which is measured from a point on the edge to.
an adjacent point on the surface of the shank, diminishes progressively from an end of the thread adjacent to the support head portion to an end of the thread adjacent to the tip of the shank. Other thread configurations may be used as desired.
Figures 5 through 14 are views of still other support devices;
Figures 15 and 16, are perspective views of further support devices with an engaging recess in each head of the device;
Figures 17 and 18 are plan views of heads of further support devices;
Figures 19a, 19b, 19c and 19d, are perspective and sectional views of another support device receiving an indicia of a pre-determined design theme is in the form of an insignia insert cap thereon; and Figures 20 and 21 are fragmentary perspective and plan views of a mold and a blank therefrom.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to the figures, particularly figures Ia to Ic; there is shown a support device 10'for supporting an article (such as, for example, a picture frame, not shown) on a structure, for example a wall 12. The support device 10 has an elongate body 14 having a support head portion 16 located at one end thereof.
The support head portion 16 includes a head 18 and a shoulder flange 20 which are separated by a neck 22. .
As will be described, the head 18 and /or neck 22 are arranged to engage the article while the shoulder flange 20 has a surface 20a for engaging a corresponding surface of the structure.
The elongate body 14 has an elongate shank portion 24 for anchoring the support device at a target site on the structure. The elongate shank portion is, in this example, screw threaded with a proximal end 24a adjacent the shoulder flange 20 and a distal end 24b, and the shank portion.24 decreases in cross-section from the proximal end to the distal end 24b.
Preferably, the elongate shank portion 24 has a helical thread 26 extending along its surface. The thread 26 has two surfaces 26a, 26b extending along its length which converge toward one another to form an edge 26c. The height of the thread, which is measured from a point on the edge to.
an adjacent point on the surface of the shank, diminishes progressively from an end of the thread adjacent to the support head portion to an end of the thread adjacent to the tip of the shank. Other thread configurations may be used as desired.
4 Of course, the elongate shank portion 24 may be of other configurations, as desired. Desirably, the elongate shank portion 24 is adapted for insertion into the target site of the structure 12, which may include wood, plastic, and paper, cardboard, concrete, brick, steel or a combination of those materials. The support device 10 is also desirably made of a material with sufficient strength to support the weight bearing load of at least one kilogram in weight, though other weights may also be suitable, as desired. A most preferred form of material for the support device 10 is metal, such as alloys of aluminum, copper, steel magnesium, and zinc.
The support head 16, in this case, has a polygonal shape in three dimensions.
The support head 16 the support head is provided with a curved outer upper surface 16a to form a "button head" and is further provided with one or more than one recess for receiving a torque tool, such as a screw driver, a knife or the like (not shown), for installing the support device 10 at the target site on the structure 12. In this case, the recess 28 for engagement of the installation tool 36 may be slotted as shown but may be of other shapes.
For instance, the recess may be in the form of a cruciform, star, rectangular or square shape or a combination thereof as shown in figures 15 through to 18.
The support head may have a slotted upper surface 1 6a when viewed in cross section (as shown in figure Ia), but may also be flat if desired. The upper surface 16a may also be curved with relatively wide or relatively narrow undulations, the latter in a corrugated form (not shown).
Still further, the upper surface 16a may be patterned, textured (as shown in selected ones of figures 5 and 9 through to 15) or otherwise provided with indicia of a predetermined design theme, to present a clean esthetically pleasing outer surface to be complementary with the decor of the vicinity of the structure.
Referring to figures 2a to 2g, another support device 30 has a neck 32 provided. with a transverse passage 34 extending therethrough for engaging an installation tool 36. As with the above mentioned torque tool, the installation tool 36 may be arranged to be hand held.
As seen in figure 2d, 2e, 2f, and 2g, the support device 30 may also be conveniently used with a support accessory 38 which also functions as the installation tool 36. The support accessory 38 is engageable with a support head portion 40 and is arranged to support an article at a location proximal or distal to the support head portion 40. In this case, the support accessory 38 includes an anchor formation having a looped.
portion 42 for engaging the neck 32 and a hooked support formation 44 spaced from the anchor formation 42 and including a support surface 44a. The support accessory 38, in this example, can be described as a support hook.
Referring to figures 3a and 3b, the support device 10 has a flat support head portion without a transverse passage through the neck, which is otherwise apparent in the support device 30 of figures 4a, 4b and 5.
The support head 16, in this case, has a polygonal shape in three dimensions.
The support head 16 the support head is provided with a curved outer upper surface 16a to form a "button head" and is further provided with one or more than one recess for receiving a torque tool, such as a screw driver, a knife or the like (not shown), for installing the support device 10 at the target site on the structure 12. In this case, the recess 28 for engagement of the installation tool 36 may be slotted as shown but may be of other shapes.
For instance, the recess may be in the form of a cruciform, star, rectangular or square shape or a combination thereof as shown in figures 15 through to 18.
The support head may have a slotted upper surface 1 6a when viewed in cross section (as shown in figure Ia), but may also be flat if desired. The upper surface 16a may also be curved with relatively wide or relatively narrow undulations, the latter in a corrugated form (not shown).
Still further, the upper surface 16a may be patterned, textured (as shown in selected ones of figures 5 and 9 through to 15) or otherwise provided with indicia of a predetermined design theme, to present a clean esthetically pleasing outer surface to be complementary with the decor of the vicinity of the structure.
Referring to figures 2a to 2g, another support device 30 has a neck 32 provided. with a transverse passage 34 extending therethrough for engaging an installation tool 36. As with the above mentioned torque tool, the installation tool 36 may be arranged to be hand held.
As seen in figure 2d, 2e, 2f, and 2g, the support device 30 may also be conveniently used with a support accessory 38 which also functions as the installation tool 36. The support accessory 38 is engageable with a support head portion 40 and is arranged to support an article at a location proximal or distal to the support head portion 40. In this case, the support accessory 38 includes an anchor formation having a looped.
