Definitions
- This invention relates to a bracket assembly, more particularly for supporting cabinets, shelves or the like, of the general kind comprising a tubular upright having in its walls a plurality of elongate slots aligned in a vertical row, and a bracket member of substantially flat construction having at one side anchoring means in the form of tongues which upon insertion into appropriately spaced apart of said slots, anchor the bracket on the upright in a substantially cantilever fashion.
- Such an assembly provides for easy vertical adjustability of the bracket with pre-determined locations.
- the tongues formed on the bracket are held in the slotted upright only by engaging the wall portions adjacent the ends of said slots, these wall portions are subjected, upon loading of the bracket, to forces which tend to bend or wear these portions when a pre-determined load on the bracket is exceeded. Consequently, unless the slotted upright is made of a robust construction, which is often undesirable from the point of view of cost and weight considerations, the admissible loading on the bracket is somewhat limited and the anchoring of the bracket in the slotted upright lacks the desired stability.
- the invention aims at providing an improved bracket assembly of the foregoing general kind both with regards to strength and stability whilst retaining a pleasing appearance of the assembly.
- the present invention consists in a bracket assembly comprising a tubular upright (as hereindefined) having a plurality of elongate slots aligned in a vertical row, and a bracket member of substantially flat construction having an anchoring portion engageable in said upright and a contiguous portion for supporting a load, said anchoring portion including at least one undercut projecting tongue which engages a slot in said upright, said tongue being of such a length that when it is fully located in said slot said undercut receives a wall portion of the upright adjacent the lower end of said slot and the free end face of the tongue abuts the inner surface of the wall of the upright opposite to that containing the slot, the end face of the bracket member extending downwardly from said undercut abutting the outer surface of the upright below the lower end of said slot.
- tubular upright used herein is intended to denote not only a single tubular member of circular or substantially rectangular cross-section but also an assembly of two or more of such members joined together along their longitudinal walls, as well as a member having a substantially S-shaped cross-section. In the latter case the slotted walls are constituted by the two outer horizontal limbs of the S-shape.
- the load applied, in use, to the bracket is to a great extent taken up by the wall of the upright against which the free end face of the tongue abuts, whilst the wall portion adjacent the lower end of the slot, which portion is engaged by the tongue undercut, serves substantially as a fulcrum for the bracket and is therefor subjected to a reduced loading in comparison to the known arrangement.
- the said contiguous portion of the bracket member for supporting a load may be in the form of an elongate substantially rectangular arm.
- the bracket assembly ullustrated in Figs. 1 to 3 comprises an upright 1 which is in the form of a steel section having an S-shape cross-section.
- the two outer horizontal limbs 2 of the S-shape are provided with a plurality of elongate slots 3 which are aligned in a vertical row.
- Each wall 4 of the upright 1 which is contiguous to the respective slotted wall 2 is unslotted as is a central common wall 5 joining the respective pairs of contiguous walls 4.
- a bracket member 6 of substantially flat elongate construction and having a thickness substantially corresponding to the width of the slots 3 is formed at one end with three projecting tongues 7 which respectively engage three adjacent slots 3 in the upright 1 and by means of which the bracket member 6 is releasably anchored in the upright 1 to project in cantilever fashion from the slotted wall 2 thereof.
- the bracket member 6 has a rectangular shape substantially along half its length 8, whereafter the bottom edge flares outwardly at 9 at an angle of 30° to the horizontal to form with the straight upper edge 10 of the bracket member 6 a widened portion which terminates in an anchoring portion 11 from the end face of which the three tongues 7 project.
- each tongue 7 is parallel to one another and extend downwardly at an angle of 30° to the horizontal upper edge 10 of the bracket member 6, that is they are parallel to the oblique edge 9 of the widened portion 11.

- the latter and the third tongue 7 are formed in a similar manner to that of the upper tongue 7 with the free end of the semi-circular recess of the lowermost tongue 7 merging with the remaining portion of the end face 17 of the anchoring portion 11, which remaining portion merges with the oblique edge 9 of the widened portion 11, preferably via a short horizontal chamfer 18.
- bracket member 6 is formed with three projecting tongues 7 it will be appreciated that more than three such vertically aligned tongues may be provided depending solely on the particular application for which the bracket is intended.
- a "light duty" bracket of narrower width may be formed with only two or even one anchoring tongue 7.
- the bracket member 6 held in a substantially horizontal position is first aligned by the end faces 14 of the projecting tongues 7 with three adjacent slots 7 in the slotted wall 2 of the S-shaped upright 1 and is then pushed in that position against the upright 1, whereby the three projecting tongues 7 slide into the three slots 7 on the three lower end edges thereof until the recesses forming the undercuts 16 in the tongues 7 come to lie with their horizontal walls on said end edges and substantially simultaneously the free end faces 14 of the tongues 7 come to abut against the central unslotted wall 5 of the upright 1. Since the tongues 7 engage the slots 3 with a sliding fit sufficient lateral support for the tongues 7 is provided by the longitudinal walls of the slots 3.

Abstract
Description
- This invention relates to a bracket assembly, more particularly for supporting cabinets, shelves or the like, of the general kind comprising a tubular upright having in its walls a plurality of elongate slots aligned in a vertical row, and a bracket member of substantially flat construction having at one side anchoring means in the form of tongues which upon insertion into appropriately spaced apart of said slots, anchor the bracket on the upright in a substantially cantilever fashion.
- Such an assembly provides for easy vertical adjustability of the bracket with pre-determined locations. However, owing to the fact that the tongues formed on the bracket are held in the slotted upright only by engaging the wall portions adjacent the ends of said slots, these wall portions are subjected, upon loading of the bracket, to forces which tend to bend or wear these portions when a pre-determined load on the bracket is exceeded. Consequently, unless the slotted upright is made of a robust construction, which is often undesirable from the point of view of cost and weight considerations, the admissible loading on the bracket is somewhat limited and the anchoring of the bracket in the slotted upright lacks the desired stability.
- The invention aims at providing an improved bracket assembly of the foregoing general kind both with regards to strength and stability whilst retaining a pleasing appearance of the assembly.
- Accordingly, the present invention consists in a bracket assembly comprising a tubular upright (as hereindefined) having a plurality of elongate slots aligned in a vertical row, and a bracket member of substantially flat construction having an anchoring portion engageable in said upright and a contiguous portion for supporting a load, said anchoring portion including at least one undercut projecting tongue which engages a slot in said upright, said tongue being of such a length that when it is fully located in said slot said undercut receives a wall portion of the upright adjacent the lower end of said slot and the free end face of the tongue abuts the inner surface of the wall of the upright opposite to that containing the slot, the end face of the bracket member extending downwardly from said undercut abutting the outer surface of the upright below the lower end of said slot.
- The term "tubular upright" used herein is intended to denote not only a single tubular member of circular or substantially rectangular cross-section but also an assembly of two or more of such members joined together along their longitudinal walls, as well as a member having a substantially S-shaped cross-section. In the latter case the slotted walls are constituted by the two outer horizontal limbs of the S-shape.
- By virtue of the construction in accordance with the invention the load applied, in use, to the bracket, is to a great extent taken up by the wall of the upright against which the free end face of the tongue abuts, whilst the wall portion adjacent the lower end of the slot, which portion is engaged by the tongue undercut, serves substantially as a fulcrum for the bracket and is therefor subjected to a reduced loading in comparison to the known arrangement.
- The said contiguous portion of the bracket member for supporting a load may be in the form of an elongate substantially rectangular arm.
- In order that the invention may be more readily understood, reference is made to the accompanying drawings which illustrate diagrammatically and by way of example embodiments thereof, and in which:-
- Fig. 1 is a cross-section on the line A-A of Fig. 2 of one embodiment of the bracket assembly in accordance with the invention,
- Fig. 2 is a top plan view of the bracket assembly,
- Fig. 3 is a partial perspective view of the bracket member of the assembly shown in Figs. 1 and 2,
- Fig. 4 is a cross-section on the line B-B of Fig. 5 of another embodiment of the bracket assembly,
- Fig. 5 is a top plan view of the bracket assembly illustrated in Fig. 4,
- Fig. 6 is a top plan view of a further embodiment of the bracket assembly,
- Fig. 7 is an exploded perspective view of the bracket assembly of Fig. 6 with the bracket arms omitted, and
- Fig. 8 shows a modified construction of the bracket arm to provide for vertical adjustability of the load supporting part of the bracket arm relative to the anchoring part and relative to the upright.
- Referring to the drawings, the bracket assembly ullustrated in Figs. 1 to 3 comprises an upright 1 which is in the form of a steel section having an S-shape cross-section. The two outer
horizontal limbs 2 of the S-shape are provided with a plurality of elongate slots 3 which are aligned in a vertical row. Each wall 4 of the upright 1 which is contiguous to the respectiveslotted wall 2 is unslotted as is a centralcommon wall 5 joining the respective pairs of contiguous walls 4. - A
bracket member 6 of substantially flat elongate construction and having a thickness substantially corresponding to the width of the slots 3 is formed at one end with three projectingtongues 7 which respectively engage three adjacent slots 3 in the upright 1 and by means of which thebracket member 6 is releasably anchored in the upright 1 to project in cantilever fashion from theslotted wall 2 thereof. Starting from its free end thebracket member 6 has a rectangular shape substantially along half itslength 8, whereafter the bottom edge flares outwardly at 9 at an angle of 30° to the horizontal to form with the straightupper edge 10 of the bracket member 6 a widened portion which terminates in ananchoring portion 11 from the end face of which the threetongues 7 project. The upper andlower edges 12;13 of eachtongue 7 are parallel to one another and extend downwardly at an angle of 30° to the horizontalupper edge 10 of thebracket member 6, that is they are parallel to theoblique edge 9 of the widenedportion 11. Thefree end face 14 of eachtongue 7 is vertical with thebottom corner 15 slightly chamfered horizontally to provide a lead-in surface facilitating insertion of thetongue 7 into the slot 3. - Each
tongue 7 is provided in itslower edge 13, at the juncture with the adjacent end face of theanchoring portion 11, with anundercut 16 which is in the form of a rectangular recess the width of which corresponds substantially to the thickness of theslotted wall 2 of the upright 1 and which receives the edge portion of the lower end of the respective slot 3 engaged by thetongue 7. For ease in manufacture, theundercut 16 in thetongue 7 is enlarged by a semi-circular recess 16'' formed in theadjacent end face 17 of theanchoring portion 11, the radius of said semi-circular recess being slightly smaller than the width of the recess in thetongue 7. The free end of the semi-circular recess merges with theend face 17 of theanchoring portion 11 which end face extends downwardly a distance substantially corresponding to the spacing between two adjacent slots 3 in the upright 1 and then merges with the upperoblique edge 12 of the adjacentlower tongue 7. The latter and thethird tongue 7 are formed in a similar manner to that of theupper tongue 7 with the free end of the semi-circular recess of thelowermost tongue 7 merging with the remaining portion of theend face 17 of theanchoring portion 11, which remaining portion merges with theoblique edge 9 of the widenedportion 11, preferably via a shorthorizontal chamfer 18. - Whilst in the embodiment described the
bracket member 6 is formed with three projectingtongues 7 it will be appreciated that more than three such vertically aligned tongues may be provided depending solely on the particular application for which the bracket is intended. Alternatively, a "light duty" bracket of narrower width may be formed with only two or even one anchoringtongue 7. - On assembly the
bracket member 6 held in a substantially horizontal position is first aligned by the end faces 14 of the projectingtongues 7 with threeadjacent slots 7 in theslotted wall 2 of the S-shaped upright 1 and is then pushed in that position against the upright 1, whereby the three projectingtongues 7 slide into the threeslots 7 on the three lower end edges thereof until the recesses forming theundercuts 16 in thetongues 7 come to lie with their horizontal walls on said end edges and substantially simultaneously the free end faces 14 of thetongues 7 come to abut against the centralunslotted wall 5 of the upright 1. Since thetongues 7 engage the slots 3 with a sliding fit sufficient lateral support for thetongues 7 is provided by the longitudinal walls of the slots 3. When a load is applied to theelongate portion 8 of thebracket 6, only a very slight pivotal movement of thebracket 6 is sufficient firmly to brace thebracket member 6 against thecentral wall 5 by way of the end faces 14 of the tongues. - The slotted upright 1 which in the described embodiment has an S-shaped cross-section is, in use, preferably covered on its two unslotted sides by cladding
panels 19 of sheet metal which are suitably attached, for example by adhesive bonding to the outer surfaces of the twounslotted walls 2 contiguous with thecentral wall 5. Thesecladding panels 19 are advantageously provided along their longitudinal edges with either inwardly or outwardly directedflanges 20 which in the attached condition of thepanels 19 come close to the longitudinal edges of the slots 3 in the upright 1 and thus laterally bound the adjacent load-supportingportion 8 of thebracket member 6 providing adatum line 21 on the one side of which only theplane part 8 of the bracket member G is visible and on the other side of which substantially only thecladding 19 is visible. Such arrangement enhances the pleasing appearance of the bracket assembly by substantially masking the slotted upright together with the portion of the bracket member engaging the slots in said upright. Thebracket member 6 and thecladding panels 19 may conveniently be chromium plated or provided with coloured enamel coating. - In the embodiment of Figs. 4 and 5 the bracket assembly comprises a tubular upright 1' having a substantially rectangular cross-section. In a wall 2', which for convenience sake will be referred to hereinafter as "the front wall", are provided a plurality of elongate slots 3' which are aligned in a vertical row. The opposite wall, i.e. the rear wall 4', is provided with a continuous longitudinal indentation 5' having a flat bottom the width of which substantially corresponds to that of the slots 3'. As a result of the indentation 5' a
longitudinal bead 5" is formed on the outer surface of the rear wall 4'. The rear wall indentation and the slots 3' have a common centre line, i.e. they face one another in parallel relationship. - A bracket member 6' of substantially flat elongate construction and having a thickness substantially corresponding to the width of the slots 3' is formed at one end with threeprojecting tongues 7' which respectively engage three adjacent slots 3' in the upright 1' and by means of which the bracket member 6' is releasably anchored in the upright 1' to project in cantilever fashion from the slotted wall 2' thereof. Starting from its free end the bracket member 6' has a rectangular shape substantially along half its length 8', whereafter the bottom edge flares outwardly at 9' at an angle of 30° to the horizontal to form with the straight upper edge 10' of the bracket member 6' a widened portion which terminates in an anchoring portion 11' from the end face of which the three tongues 7' project. The upper and lower edges 12';13' of each tongue 7' are parallel to one another and extend downwardly at an angle of 30° to the horizontal upper edge 10' of the bracket member 6', that is they are parallel to the oblique edge 9' of the widened portion 11'. The free end face 14' of each tongue 7' is vertical with the bottom corner 15' slightly chamfered at an angle to the horizontal to provide a lead-in surface facilitating insertion of the tongue 7' into the slot 3'.
- Each tongue 7' is provided in its lower edge 13', at the juncture with the adjacent end face of the anchcring portion 11', with an undercut 16' which is in the form of a rectangular recess the width of which corresponds substantially to the thickness of the slotted wall 2' of the upright 1' and which receives the edge portion of the lower end of the respective slot 3' engaged by the tongue 7' is enlarged by a trapezoidal 16" recess formed in the adjacent end face 17' of the
anchoring portion 11, the width of said trapezoidal recess being slightly smaller than the width of the recess in thetongue 7. The free end of the trapezoidal recess merges with the end face 17' of the anchcring portion 11' which end face extends downwardly a distance substantially corresponding to the spacing between two adjacent slots 3' in the upright 1' and then merges with the upper oblique edge 12' of the adjacent lower tongue 7'. The latter and the third tongue 7' are formed in a similar manner to that of the upper tongue 7' with the free end of the trapezoidal recess of the lowermost tongue 7' merging with the remaining portion of the end face 17' of the anchoring portion 11', which remaining portion merges with the oblique edge 9' of the widened portion 11', preferably via a short horizontal chamfer 18'. - Whilst in the embodiment described the bracket member 6' is formed with three projecting tongues 7' it will be appreciated that more than three such vertically aligned tongues may be provided depending solely on the particular application for which the bracket is intended. Alternatively, a "light duty" bracket of narrower width may be formed with only two or even one anchoring tongue 7'.
- The bracket assembly of Figs. 4 and 5 is assembled in a manner similar to that already described with reference to the embodiment of Figs. 1 to 3. The indentation 5' formed in the rear wall 4' of the upright 1' constitutes, in the assembled condition, a locating means for the free end face 14' of each tongue 7' to prevent lateral movement of the bracket member 6' relative to the upright 1' and thus provide increased rigidity when the bracket assembly is in use.
- The embodiment of Figs. 6 and 7 utilizes two uprights 1', used in the embodiment of Figs. 4 and 5, to form a substantially box-section upright 1" in which the uprights 1' are joined together so as to contact one another along their longitudinal walls 4' provided with the indentations 5'. The two uprights 1' are held together in the juxtaposed position by means of two
identical spring clips 22 which engage the pair of uprights 1' from two opposite sides so as substantially to embrace them, and leaving only a comparativelynarrow gap 23 substantially corresponding to the width of the slots 3' which gap is defined by outwardly flaringlugs 24, two of which are formed at each end of the twoclips 22. Similar to the embodiment of Figs. 1 to 3, the composite upright 1" is, in use, covered on its two unslotted sides by cladding panels 19' of sheet metal which are provided along their longitudinal edges with inwardly directed flanges 20' which are engaged by thelugs 24 of theclips 22 to retain the panels 19' in position. In the assembled condition theflanges 20 come close to the longitudinal edges of the slots 3' in the upright 1" and thus laterally bound the adjacent load-supporting portion 8' of the bracket member 6' and provide thedatum line 21. The bracket members 6' are constructed and mounted in the upright 1" in a manner similar to that as already described with reference to Figs. 4 and 5. - In the embodiment of Fig. 8 the bracket member is made of two
main parts load supporting portion 25 of the bracket member relative to theanchoring portion 26 and the upright (not shown) and which portions are securable together in an adjusted position. For this purpose the widenedportion 11" of the bracket member is modified by having a plane end face (i.e. without projecting tongues) which has acurved portion 27 at its lower end and which merges with theoblique edge 9" of the widenedportion 11". Aplate member 26 having the shape of a substantially isosceles triangle is pivotally secured adjacent the apex of the triangle to the widenedportion 11" to lie in a first position (solid lines) flat thereon with one equal side of thetriangular plate 26 flush with the adjacentoblique edge 9" of the widenedportion 11". The base of thetriangular plate 26 has three projecting congues 7' described with reference to Figs. 4 and 5. - The
plate member 26 has, starting from the apex, three tappedholes Hole 28 serves as fulcrum for a locatinghole 31 or 32 provided in thepart 25.Holes 29 and 30 serve as locating holes for sixholes 34 arranged in anarcuate slot 33. Twoscrews 35;36 secure the twomain parts 25;26 of the bracket member together. In the position shown in solid lines (part 25 horizontal), the locatinghole 31 of thepart 25 is in register with the tappedhole 28 of thepart 26 and one of the holes (upper end hole) 34 in theslot 33 is in register with the tapped hole 30 of thepart 26. In the position shown by chain- dotted lines (part 25 inclined downwardly) thefulcrum 28;31 remains the same but afourth hole 34 from the top is in register with the locating hole 30 ofpart 26. In the upwardly inclined position of part 25 (broken lines) the locating hole 32 ofpart 25 is in register with the tappedhole 28 and one hole 34 (second from top) is in register with the tappedhole 29 ofpart 26. - Instead of the tapped holes and locating holes the two cooperating
main parts 25;26 of the bracket member may be provided with detent means (not shown) for securing an adjusted position of the bracket arm. In order that thepart 25 lies in one plane with the tongues 7' of thepart 26 the latter is suitably cranked along a line adjacent the recesses 16' in thepart 26.
