Description
1~323~
This invention relates to modular di~play structures for use in shop displays and the like.
It has become common practice to provide parts which can be assembled into various display structures so that shops can present different displays on a regular basis. The structures are designed so that shop assistants can dismantle them and assemble them in a different arrangement~ There are a number of desirable criteria afecting the design of such structures.
Firstly, because of the type of environment, the structure should be pleasing in appearance no matter how it is assembled and should not display any obvious means of connection between the parts of the structure~ Further, sufficient different parts should be provided so that a great variety of shapes of structure can be created to satisfy different needs for 15- displaying various types of products. Of course the assembly and disassembly should require a minimum of tools and if tools are necessary, they should be of a variety commonly available.
Another important consideration is the number of parts needed for different arrangements. Obviously, if every arrangement required different parts, then the shopkeeper would have to have a large inventory of parts. By contrast, if many arrangements can be made from a limited number of parts, then the shopkeeper is in a position to change the display structure regularly with minimum storage requirement and therefore minimal initial capital outlay.
~;32~3 Most display arrangements are made from a combination of upriyhts and horizontal elements which meet one another at corner pieces. In order to accommodate panels in the form of mirrors, backg!ound walls, etc., the arrangement of elements should be such that they are based on a fixed rnodule. This can be done quite readily but it can require a large number of parts For instance if two elements are arranged in parallel with their centers spaced by modular distance, then a connectiny element will have to have a length less than the modular distance to accommodate the width of the parallel elements.
Consequently, if these elements are now spaced apart by a distance twice the module length, then the connecting piece will have to have a length which is twice the module length less the thickness of an element. Consequently, two single elements cannot be connected together to replace the connecting piece which is approximately twice the module length. This means that many pieces will be required to satisfy different display arrangements. Nevertheless, such structu~es have been accepted and are in use A further consideration is connections between the parts.
Snap fittings have been used in the past and these quite often require special tools to dismantle and are somewhat awkward because once the display structure is assembled it is difficult to find a place to start to dismantle the parts. It is therefore generally accepted that some kind of simple release B
~ ~63233 mechanism operated by conventional tools is more desirable.
According to the present invention, a framework is provided which can be assembled, using a screwdriver alone, into many configurations using a minimum of parts. To achieve this, the elements forming the framework can be connected to one another in alignment without affecting modular spacing or they can be connected at corner pieces, again without affecting the modular spacing.
Accordingly in one of its aspects the invention provides a modular framework based on a modular length "M" for use in shop displa~s. The framework includes a plurality of elongate elements having respective longitudinal axes and end openings, and corner pieces for positioning at the junctions between adjacent elementsO ~espective ones of the longitudinal axes of 15- the elongate elements meet at a point, the corner pieces having respective end portions in alignment with the adjacent elements and each of the end portions extending from the point along the corresponding one of the longitudinal axis a distance "D". Each of the portions terminates at an end opening and couplings are provided for positioning between the corner piece and the adjacent elements. The couplings have engagement portions for engaging the end openlngs of the end portions and the elongate elements and a body portion of the coupling spaces each adjacent end portion and elongate element a distance "S". The Length of each of the elongate elements sati~fies the equation ~3;~33 L ~ M(K/2 + l) - 2(D + S) where "K" is a whole number.
According to the present invention, a framework is provided which can be assembled, using a tool such as a screwdriver, into many configurations using a minimum of parts. To achieve this, the elements forming the framework can be connected to one another in alignment without affecting modular spacing or they can be connected at corner pieces, again without affecting the modular spacing.
The invention will be better understood with reference to the drawings, in which:

~63~3~
Reference is first made to Fig. 1 which illustrates an exemplary display structure 20 consisting of a base arrangement 22, uprights such as upright 24, and a top arrangement 26.
As best seen in the ~op arrangement 26, it is made up of a S series of shorter first elements 28a, 28b, etc. and one longer element 30. These element~ are interconnected by corner pieces in the form of L-shaped connectors 32a, 32b, etc.,T-shaped connector 34, and in-line connector 36. The mechanical characteristics of these connectors will be described with reference to other drawings but for the moment it is noteworthy that the elements 28a, etc. are of a length less than the modular length shown as "M" in various places on the drawing.
However, the lengths of these elements is constant regardless of theix respective positions in the structure as will be 15- explained. Similarly, a relationship exists between the combined lengths of two of these elements, 28d, 28e, and the element 30 which essentially spans two modules. The arrangement is Ruch that regardless of how the structure is built, these elements will always represent boundaries o~ square modules having a side length "M".
The base arrangement 22 is built in a similar fashion to that of the top arrangement and the uprights can take a number of different forms depending upon the uses required. For the sake of a simple drawings, the upright 24 is square in cross section and typical also of uprights 38, 40. By contrast, 23~3 upriyhts 42 and 44 are cylindricalO However, as will be explained, the uprights can take a number of forms suitable for supporting shelving, etc. and also can carry different finishes to make the structure more attractive An example of this flexibility is illustrated briefly in Fig. 2 which shows the top of a panel having circular side depressions 46, 48 spaced for engagement with the uprights 42, 44 to provide a wall at this end of the structure.
Reference is next made to Fig. 3 which illustrates an L-shaped connector 32d having sides based on a width "A" to give the legs square cross-sections of side "A". The connector 32d is attached to exemplary elements 28c and 28d which preferably also have square transverse cross-sections of side "A".. It can be seen in Fig. 3 that the connector 32d includes a first portion 50 extending in alignment with element 28c and spaced from it by a c~upling 52 as will be described. Similarly, a portion 54 of the connector 32d extends in alignment with element 28d for connection to this element by a coupling 56.
The portions 50, 54 end in axial openings such as opening 58 at the end of portion 54. This opening is similar to an opening 60 in the end of element 28d which also receives the coupling 56.
The portions 50, 54 of the L-shaped connector 32 extend from a point denoted by the reference numeral 62 and indicating where ~he axes of elements 28c, 28d would meet. The portions extend from this point a distance "D" (which preferably equals B
~Zi3~33 1.5A) and the coupling 52 spaces element 28c from portion 50 by a distance "S". This spacing will be better understood with reference to coupling 56. Here it will be seen that the coupling consists esentially of a first engagement portion 64 to one side of a body portion 66 and a second engagement portion 68 at the other side of this body portion. Portion 6~ enters opening 60 and portion 68 enters opening 58 until the body portion is in engagement with the ends of the element 28d and L-shaped connector portion 54. The coupling portions 64, 68 are formed by two metal bars 70, 72 which extend through a central opening in the body portion 66 and are retained in position by the combination of a screw 74 passing through the body portion and threaded in the bar 70, and a spring 76 located in seatings on facing surfaces of the bars 70, 72 to bias the bars outwardly 15- but yet provide resilience for entering the coupling in the openings 58, 60. The arrangement is such that when the screw 74 is operated, the bars can be made to moYe away from one another because the screw pushes on the bar 72 to bias it away from the bar 70 through which it is threaded. With this arrangement the bars can be brought into locking engagement within the openings 58, 60 to retain the element 28d in fixed relationship relative to the L-shaped connector 32d.
The parts described so far with reference to Fig. 3 appear in Fig. 1 but in Fig. 3 a different upright 78 is used for the purposes of demonstrating an alternative configuration of 1~3233 upright. As seen in this figure upright 78 consists of a central tubular rnember 80 extending the complete length of the upright and faced with a pair of wood cheeks 82, 84 which serve to improve the appearance of the upright because they can be of hardwood, which is stained, or other material to yive some colour to the structure. It is also of interest that the tubular member 80 includes a series of openings 86 accessible between the cheeks 82, 84 to receive conventional shelving and other devices which lock into pairs of such openings in the upright. A coupling 88 is provided for attaching the upright 78 into the element 32d and an opening in the underside of the element is provided although it is not shown in the drawing.
The coupling 88 engages in the tubular member 80 although an alternative arrangement for this will be shown with reference to lS Fig. 5.
Reference is next made to Fig. 4 which shows a series of connectors used to assemble display structures of various types. Starting from the left, there is a connector such as that shown as 36 in Fig. l for connecting aligned pairs of elongate elements such as 28d and 28e in Fig. l. It should be noted that an opening is provided in the underside of all of these connectors so that they can also receive uprights, ; cross-bars, accessories, etc. in the manner described with reference to the upright 78 in Fig. 3. Continuing from the left in Fig. 41 the next connector shown is an L-shaped connector such as connec~or 32d described with reference to Fig. 3. Next ~' ~i3Z33 is a T-shaped connector such as connector 34 shown in Fig. 1 and then there is a cross-over connector 90 which is not used in the Fig. 1 structure but would obviously be used where four elongate elements come together at one point. Next there is a connector 9~ used wherever an end piece i6 required on an elongate element and this can also receive an uprightO To the right of this is a type of connector 94 which is effectively a combination coupling and connector because the ~pper portion (as drawn) designated by the distance "D - A/2" permits the use of elements such as 28d (Fig~ 3) both at the periphery of a framework where they meet connectors 32d, etc. and also in locations such as that shown in Fig. 5 where the connector 94 is used. Consequently, the number of different lengths of elements is kept to a minimum. Of course in the preferred embodiment where D = 1.5A, then 15_ D - A/2 = A.
It will be seen by a comparison of the connectors shown in Fig. 4 and with reference to the dimension "D" shown on each of the connectors, that there i~ a consistency in dimensioning corresponding to the dimensions "D" designated on the portions 50, 54 of the L-shaped connector 32d shown in Fig~ 3. This is because, as described with reference to Fig. 3, the portions of the connectors extending in alignment with the elongate elements have a length "D" extending from a point of intersection of the center lines of the elementsO Of course in ~he first connector 34 shown in FigO 4 there is no intersection but it will be _ 9 _ ~2~23~
understood that this is equivalent because if this connector is divided into two, the resulting lengths will be equal to "D".
Put another way, where the center line~ of the elongate elements meet the center line of the upright, this forms a point from which the measurement can also be made. Similarly, the measurement "D" can be made on the connector 92 between these axes.
Reference is again made to FigO 5 which illustrates some typical parts in more detail than shown in previous drawings.
Firstly, a special connector 94 (similar to that shown in Fig.
4) will be described in use to attach an element 96 at right angles to another element 98~ The connector 94 consists of a central spacer 100 in the form of a block having a square cross~section of side "A", and two engagement portions 102, 104 15- extending through the block 100 and adjacent collars 106, 108.
These collars have an axial length equal to "S" and the total length of the block and one of these collars is equal to "D ~ A/2" (and in the preferred embodiment "A"). The connector 94 also includes a pair of long bars 110, 112 forming the engagement portions 102, 104 and arranged in similar fashion to the bar 70, 72 described with reference to Fig. 3. Two screws 114 and 116 are used to separate the bars for engagement in a blind opening 118 in the element 98 and a similar blind opening 120 in the end of element 96. After assembly, because the combined length of the collar 106 and spacer 100 is equal to 3~33 "D - A/2", the effect is similar to using for instance a T-shaped connector between a pair of aligned elements because a portion of the T-shaped connector would be equivalent to using connector 9~ plus a coupling such as coupling 56 described with reference to Fig. 3. Consequently the connector 94 makes it possible to attach elements 96 to positions between the ends of other elements such as element 98.
~ he position of blind opening 118 in element 98 is such that it is midway between a pair of similar blind openings spaced the modular distance "M" apart on the underface of the element as drawn. In general, blind openings are provided at modular distances apart on two of the faces with two of the openings staggered as shown for element 98 and also for element 96. However, the distance from the last opening to the end of 15- the element has to be defined in relation to the parameters "D"
and "S" as will be described. This distance is referred to as "E" in Fig~ 5.
It will be evident that modular distances have to be measured from the centers of the elements and this is why in Fig. 3 the distance "D" is measured from the confluence of the axes of the elements meeting at this connectorO The distance from point 62 in Fig. 3 to the first opening in the element 28d would be equal to M/2 and is consequently shortened by the amount D + S. Consequently, from the last opening in the element 28d, the distance E (Fig. 5) is equal to M/2 D S.
1~ti323~
As a result, for a general element, the length is given by the equation:
L = M(K/2 + 1) - 2~D + S) where K is a whole number.
For the pre~erred case where D = 1.5A, this equation becomes:
L = M(K/2 ~1) - 2(1.5A + S) or alternatively, L = M(K/2 + 1) - (3A ~ 2S) Fig. 5 also shows the connection of an upright 122 to the 15- underside of element 98 using a coupling 124 built into the upright 122. As mentioned earlier, this is an alternative to the upright 78 shown in Fig. 3 because the central tube used in the upright in effect forms collar 126 and the screw is located in this part to operate the coupling.
Fig. S also shows one of the attachments which could be used in the structure. A light fitting 128 has a custom made base 130 having the same form of coupling 132 described previously and engagable in opening 134 of the element 96.
Another feature of the elements such as element 96 is noteworthy. Because the openings are provided in two sides and 12~i3;~33 staggered by half a module length, it is possible to rotate the element to connect in different directions. It will be evident that the invention provides an infinite number of permutations of framework consistent with the basic requirement of dimensional relationships previously described. All such structures are within the scope of the invention as claimed.
Also the structure can be readily attached to a wall, etc. by drilling through from the bottom of a blind hole to provide for a screw which, after assembly, is hidden in the blind hole.
This invention relates to modular di~play structures for use in shop displays and the like.

This is because, as described with reference to Fig. 3, the portions of the connectors extending in alignment with the elongate elements have a length "D" extending from a point of intersection of the center lines of the elementsO Of course in ~he first connector 34 shown in FigO 4 there is no intersection but it will be _ 9 _ ~2~23~
understood that this is equivalent because if this connector is divided into two, the resulting lengths will be equal to "D".
Put another way, where the center line~ of the elongate elements meet the center line of the upright, this forms a point from which the measurement can also be made. Similarly, the measurement "D" can be made on the connector 92 between these axes.
Reference is again made to FigO 5 which illustrates some typical parts in more detail than shown in previous drawings.
Firstly, a special connector 94 (similar to that shown in Fig.
4) will be described in use to attach an element 96 at right angles to another element 98~ The connector 94 consists of a central spacer 100 in the form of a block having a square cross~section of side "A", and two engagement portions 102, 104 15- extending through the block 100 and adjacent collars 106, 108.
These collars have an axial length equal to "S" and the total length of the block and one of these collars is equal to "D ~ A/2" (and in the preferred embodiment "A"). The connector 94 also includes a pair of long bars 110, 112 forming the engagement portions 102, 104 and arranged in similar fashion to the bar 70, 72 described with reference to Fig. 3. Two screws 114 and 116 are used to separate the bars for engagement in a blind opening 118 in the element 98 and a similar blind opening 120 in the end of element 96. After assembly, because the combined length of the collar 106 and spacer 100 is equal to 3~33 "D - A/2", the effect is similar to using for instance a T-shaped connector between a pair of aligned elements because a portion of the T-shaped connector would be equivalent to using connector 9~ plus a coupling such as coupling 56 described with reference to Fig. 3. Consequently the connector 94 makes it possible to attach elements 96 to positions between the ends of other elements such as element 98.
~ he position of blind opening 118 in element 98 is such that it is midway between a pair of similar blind openings spaced the modular distance "M" apart on the underface of the element as drawn. In general, blind openings are provided at modular distances apart on two of the faces with two of the openings staggered as shown for element 98 and also for element 96. However, the distance from the last opening to the end of 15- the element has to be defined in relation to the parameters "D"
and "S" as will be described. This distance is referred to as "E" in Fig~ 5.
It will be evident that modular distances have to be measured from the centers of the elements and this is why in Fig. 3 the distance "D" is measured from the confluence of the axes of the elements meeting at this connectorO The distance from point 62 in Fig. 3 to the first opening in the element 28d would be equal to M/2 and is consequently shortened by the amount D + S. Consequently, from the last opening in the element 28d, the distance E (Fig. 5) is equal to M/2 D S.
1~ti323~
As a result, for a general element, the length is given by the equation:
L = M(K/2 + 1) - 2~D + S) where K is a whole number.
For the pre~erred case where D = 1.5A, this equation becomes:
L = M(K/2 ~1) - 2(1.5A + S) or alternatively, L = M(K/2 + 1) - (3A ~ 2S) Fig. 5 also shows the connection of an upright 122 to the 15- underside of element 98 using a coupling 124 built into the upright 122. As mentioned earlier, this is an alternative to the upright 78 shown in Fig. 3 because the central tube used in the upright in effect forms collar 126 and the screw is located in this part to operate the coupling.
Fig. S also shows one of the attachments which could be used in the structure. A light fitting 128 has a custom made base 130 having the same form of coupling 132 described previously and engagable in opening 134 of the element 96.
Another feature of the elements such as element 96 is noteworthy. Because the openings are provided in two sides and 12~i3;~33 staggered by half a module length, it is possible to rotate the element to connect in different directions. It will be evident that the invention provides an infinite number of permutations of framework consistent with the basic requirement of dimensional relationships previously described. All such structures are within the scope of the invention as claimed.
Also the structure can be readily attached to a wall, etc. by drilling through from the bottom of a blind hole to provide for a screw which, after assembly, is hidden in the blind hole.
