Abstract
A bracing system for a wall hung sink mountable to a wall by fasteners. The bracing system comprises at least one bracket mountable to the wall and a brace member extendable between the bracket and the underside of the sink. The brace member has a first end engagable with the sink and a second end removably retained in the bracket by an adjustable support to accommodate sinks of different dimensions. The bracing system is usable in conjunction with conventional sink hanging brackets that support only the rear edge of the sink making the sinks prone to sagging from the wall particularly if force is applied to the front edge of the sink.
Description
BRACE FOR WALL HUNG SINKS
FIELD OF THE INVENTION
This invention relates to a brace for reliably supporting wall hung sinks.
BACKGROUND OF THE INVENTION
Wall hung sinks that are supported on a centrally located wall bracket at the rear of the sink are common in public restrooms as they are relatively inexpensive and easy to install. Because sinks mounted in this manner are supported primarily at their rear edge immediately adjacent the wall, they are prone to sagging or even breaking away from the wall if a force is applied to the front edge of the sink. To some extent, the drain pipe extending between the sink and the wall provides some additional support for the weight of the sink, but the pipe is not designed for bearing a load. Modern drain pipes manufactured from plastic are particularly unsuited to bearing any loads.
Prior art sink mounting arrangements have relied on upstanding posts extending between the floor and the front edge of the sink to better support the sink. The posts represent additional cost and tend to render the sink inaccessible to wheelchairs by blocking the space below the sink.
Applicant is aware of the following patents directed to wall mounted brackets for sinks or other bathroom fixtures:
United States Patent No. 953,924 to Reynolds United States Patent No. 1,006,361 to Daly United States Patent No. 1,253,924 to Barnett United States Patent No. 1,722,614 to Watrous United States Patent No. 1,740,553 to Schmiedeknecht United States Patent No. 2,583,922 to Zummach United States Patent No. 2,766,461 to Zinkil et al.
United States Patent No. 3,012,250 to Morris United States Patent No. 3,428,968 to Ory, Jr. et al United States Patent No. 3,440,670 to Van Hoof These patents disclose brackets intended to reliably attach a fixture, such as a sink, to the wall. Any of the designs for sinks that use bracing arms extending from the wall to the sink rely on fixed arms for strength. Depending on the size and/or design of the sink, a fixed bracing arm may not adequately support the front edge of the sink.
SUMMARY OF THE INVENTION
Applicant has developed a bracing system for wall mounted sinks that employs adjustable brace members or arms extending from the wall to the underside of the sink to reliably support all manner of sinks. The length and wall anchoring location of the brace members are adjustable to permit the brace members to extend to the front edge of the sink for proper support. In particular, many sinks are formed with cavities at the front edge to receive a bracing support, and the design of the bracing system of the present invention is intended to ensure that the brace member extends from the wall to be securely received in the cavities no matter the dimensions of the sink being supported.
Accordingly, the present invention provides a bracing system for a wall hung sink mountable to a wall by fasteners, the bracing system comprising:
at least one bracket mountable to the wall;

BRIEF DESCRIPTION OF THE DRAWINGS
Aspects of the present invention are illustrated, merely by way of example, in the accompanying drawings in which:
Figure 1 is an exploded perspective view showing the components of the bracing system of the present invention;
Figure 2 is a side elevation view of the bracing system of the present invention in place supporting a sink;
Figure 3 is a detail plan view of the outer portion of the wall mounted bracket member used with the bracing system of the present invention;
Figure 4 is a detail side view of the outer portion of the wall mounted bracket member of Figure 3;
Figure 5 is a detail view of the inner portion or backing plate of the bracket member; and Figure 6 is a detail view of the end of the brace member for insertion into a pre-formed cavity at the front edge of a sink.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to Figure 1, there is shown an exploded view of a conventional sink 2 mountable to a wall using a conventional wall hanging bracket 6.that engages the rear edge 8 of the sink. To ensure that sink 2 is reliably mounted to wall 4, a bracing system according to a preferred embodiment of the present invention is used to provide additional support for the weight of the sink.
The bracing system comprises at least one bracket 10 mountable to wall 4 by conventional screw fasteners 12.
In the illustrated embodiment, a pair of brackets 10 are used, one at each side of sink 2. A brace member 20 is associated with each bracket 10 and extends between the bracket and the underside of the sink 2. Each brace member 20 has a first end 22 engagable with the sink and a second end 24 removably retained in bracket 10 by an adjustable support 30.
Figures 3 to 5 provide detail views of wall mountable bracket 10. The bracket is formed from two parts. There is an outer portion 10', preferably comprising a strip of mild steel formed with a central U
shaped bend 14 separating flat co-planar ends 15 and 16 that receive fasteners 12. There is also an inner portion 10" comprising a flat strip of mild steel adapted to be mounted adjacent wall 4 beneath outer portion 10'. The ends of inner portion 10" and outer portion 10' have alignable openings 17 and 18 drilled therethrough so that assembled bracket 10 can be secured to wall 4 by screw fasteners 12. Preferably, bracket 10 will be positioned adjacent studs underlying wall 4 to _ 5 _ ensure that the bracket is securely attached. Openings 18 are slotted to permit some adjustment of the position of assembled bracket 10 on wall 4.
Central U shaped bend 14 of outer portion 10' is formed with elongate slot 19 to receive second end 24 of brace member 20. Elongate slot 19 houses adjustable support 30 that supports second end 24 of brace member 20. In a preferred embodiment, adjustable support 30 comprises a locking member 31 in the form of a nut and bolt combination 34. As best shown in Figure 4, the shaft 35 of bolt 36 extends through slot 19. The bolt head 38 is selected so that it is too large to fit through slot 19. Nut 37 is tightened onto shaft 35 from the opposite side of portion 10' to clamp the combination in place against the sides of slot 19 between nut 37 and bolt head 38.
Locking member 31 is tightened into place at a desired location within slot 19 to support second end 24 of brace member 20 as it extends through slot 19 to abut inner portion 10" . Essentially, locking member 31 blocks slot 19 at a desired location to support end 24 of brace member 20 against downward vertical movement within the slot. The sides of slot 19 prevent lateral movement of end 24. In addition, end 24 engaging against inner portion 10" of bracket 10 braces the end against horizontal movement and prevents the end from puncturing wall 4.
Moving locking member 31 involves loosening nut 37 on bolt shaft 35 and sliding the locking member within the slot to a desired location. As best shown in Figure 4, nut 37 is accessible from the side of bracket 10 so that a first wrench can hold nut 37 still while a second tool is used to rotate bolt head 38 to loosen or tighten the nut on the shaft.
Brace member 20 is preferably a rod of generally cylindrical cross-section. A rod of 3/8 inch diameter mild steel has been found to be suitable. As best shown in Figure 6, first end 22 of brace member 20 is preferably bent into a generally S-shaped portion 26 for insertion into a pre-formed cavity 40 at the underside of the front edge of the sink. Such cavities are routinely formed in sinks to accept bracing members. End 22 is preferably covered by a resilient cap 23 which serves as a cushion to protect the ceramic material of sink 2 from contact with the metal end of brace member 20. S-shaped portion 26 is formed with flanges 27 to retain a resilient washer 28. Cap 23 also assists in maintaining washer 28 in place. Washer 28 is preferably slightly oversized for fitting within opening 40, and is distorted on insertion to fractionally lock end 22 within cavity 40.
As best shown in Figure 2, installation of the bracing system of the present invention involves supporting sink 2 initially on a conventional central rear wall bracket 6. Bracket members 10 are then attached to the wall directly below the sink at each side of the side. Each bracket member 10 is mounted to the wall using upper and lower threaded fasteners 12 such as self-tapping screws or bolts. The upper threaded fastener 12 is preferably common to both the sink and the bracket member and extends through a conventional mounting hole in the sink and the aligned slot opening 18 of bracket member 10. A brace member 20 is then inserted by end 22 into a cavity 40 at one side of the sink. The brace member is cut to length using a hack saw or other suitable tool to create end 24 that is insertable into slot 19 of bracket member 10 to engage inner portion 10"
of the bracket. If desired, end 24 can be bent into a rounded end to abut portion 10" . End 24 extends into _ 7 _ slot 19 above adjustable support 30 which is positioned initially at the bottom of slot 19. Adjustable support 30 is then slid upwardly in slot 19 to engage and support end 24 against vertical movement within the slot by locking the support in place. In the illustrated embodiment, this involves tightening nut 37 on bolt shaft 35 to clamp the adjustable support in place in slot 19.
The process is repeated for the other side of the sink.
Although the present invention has been described in some detail by way of example for purposes of clarity and understanding, it will be apparent that certain changes and modifications may be practised within the scope of the appended claims.
The bracing system of the present invention is preferably used in conjunction with conventional sink hanging brackets to ensure that the sink is reliably supported and able to withstand a significant force applied to the front edge of the sink.

The bracing system comprises at least one bracket 10 mountable to wall 4 by conventional screw fasteners 12.
In the illustrated embodiment, a pair of brackets 10 are used, one at each side of sink 2. A brace member 20 is associated with each bracket 10 and extends between the bracket and the underside of the sink 2. Each brace member 20 has a first end 22 engagable with the sink and a second end 24 removably retained in bracket 10 by an adjustable support 30.
Figures 3 to 5 provide detail views of wall mountable bracket 10. The bracket is formed from two parts. There is an outer portion 10', preferably comprising a strip of mild steel formed with a central U
shaped bend 14 separating flat co-planar ends 15 and 16 that receive fasteners 12. There is also an inner portion 10" comprising a flat strip of mild steel adapted to be mounted adjacent wall 4 beneath outer portion 10'.

Preferably, bracket 10 will be positioned adjacent studs underlying wall 4 to _ 5 _ ensure that the bracket is securely attached. Openings 18 are slotted to permit some adjustment of the position of assembled bracket 10 on wall 4.
Central U shaped bend 14 of outer portion 10' is formed with elongate slot 19 to receive second end 24 of brace member 20. Elongate slot 19 houses adjustable support 30 that supports second end 24 of brace member 20. In a preferred embodiment, adjustable support 30 comprises a locking member 31 in the form of a nut and bolt combination 34. As best shown in Figure 4, the shaft 35 of bolt 36 extends through slot 19. The bolt head 38 is selected so that it is too large to fit through slot 19. Nut 37 is tightened onto shaft 35 from the opposite side of portion 10' to clamp the combination in place against the sides of slot 19 between nut 37 and bolt head 38.
Locking member 31 is tightened into place at a desired location within slot 19 to support second end 24 of brace member 20 as it extends through slot 19 to abut inner portion 10" . Essentially, locking member 31 blocks slot 19 at a desired location to support end 24 of brace member 20 against downward vertical movement within the slot. The sides of slot 19 prevent lateral movement of end 24. In addition, end 24 engaging against inner portion 10" of bracket 10 braces the end against horizontal movement and prevents the end from puncturing wall 4.
Moving locking member 31 involves loosening nut 37 on bolt shaft 35 and sliding the locking member within the slot to a desired location. As best shown in Figure 4, nut 37 is accessible from the side of bracket 10 so that a first wrench can hold nut 37 still while a second tool is used to rotate bolt head 38 to loosen or tighten the nut on the shaft.
Brace member 20 is preferably a rod of generally cylindrical cross-section. A rod of 3/8 inch diameter mild steel has been found to be suitable. As best shown in Figure 6, first end 22 of brace member 20 is preferably bent into a generally S-shaped portion 26 for insertion into a pre-formed cavity 40 at the underside of the front edge of the sink. Such cavities are routinely formed in sinks to accept bracing members. End 22 is preferably covered by a resilient cap 23 which serves as a cushion to protect the ceramic material of sink 2 from contact with the metal end of brace member 20. S-shaped portion 26 is formed with flanges 27 to retain a resilient washer 28. Cap 23 also assists in maintaining washer 28 in place. Washer 28 is preferably slightly oversized for fitting within opening 40, and is distorted on insertion to fractionally lock end 22 within cavity 40.
As best shown in Figure 2, installation of the bracing system of the present invention involves supporting sink 2 initially on a conventional central rear wall bracket 6. Bracket members 10 are then attached to the wall directly below the sink at each side of the side. Each bracket member 10 is mounted to the wall using upper and lower threaded fasteners 12 such as self-tapping screws or bolts. The upper threaded fastener 12 is preferably common to both the sink and the bracket member and extends through a conventional mounting hole in the sink and the aligned slot opening 18 of bracket member 10. A brace member 20 is then inserted by end 22 into a cavity 40 at one side of the sink. The brace member is cut to length using a hack saw or other suitable tool to create end 24 that is insertable into slot 19 of bracket member 10 to engage inner portion 10"
of the bracket. If desired, end 24 can be bent into a rounded end to abut portion 10" . End 24 extends into _ 7 _ slot 19 above adjustable support 30 which is positioned initially at the bottom of slot 19. Adjustable support 30 is then slid upwardly in slot 19 to engage and support end 24 against vertical movement within the slot by locking the support in place. In the illustrated embodiment, this involves tightening nut 37 on bolt shaft 35 to clamp the adjustable support in place in slot 19.
The process is repeated for the other side of the sink.
Although the present invention has been described in some detail by way of example for purposes of clarity and understanding, it will be apparent that certain changes and modifications may be practised within the scope of the appended claims.
