DESCRIPTION OF THE INVENTION The present invention relates to an improved mounting arrangement suitable for use with an interior space dividing arrangement having a plurality of panels or other space-dividing elements rotatably mounted on a common post.

It is a primary object of the present invention to provide an improved mounting arrangement suitable for use with an interior space dividing system whereby two space-dividing elements mounted on a common post can be rotated through various angular positions or can be rotated parallel to each other for convenient storage and relocation of the space dividing system.

It is another object of the present invention to provide an improved mounting arrangement for use with an interior space dividing system whereby two space-dividing elements may be rotated through an arc in excess of 180 or can be rotated closely parallel to each other, thereby allowing for greater versatility in the interior space-dividing arrangement.

A further object of the present invention is to provide an improved mounting arrangement suitable for use with an interior space-dividing system whereby an interconnected series of space-dividing elements can be folded accordian style into a compact series of parallel members for convenient storage and relocation, or can be extended outwardly when in service as a space divider.

Yet another object of the present invention is to provide an improved mounting arrangement suitable for use with an interior space dividing system, which permits a channel member to be positioned between the supporting post and the dividing elements without screws or additional restraints of any kind, and which channel member effectively blocks any views between the supporting post and the elements.

Still another object of the present invention is to provide such an improved mounting means whereby a plurality of supporting posts can be interconnected, each post being capable of receiving as many as four space-dividing elements, allowing for a multitude of dividing arrangements, while the entire system is capable of folding compactly for storage or relocation.

Another object of the present invention is to provide such an improved mounting means suitable for use with an interior space-dividing system which permits a decorative trim to be positioned to cover the screws that secure the mounting brackets to the space-dividing elements.

Other objects and advantages of the invention will be apparent from the following detailed description taken in connection with the accompanying drawings, in which:

FIG. I is a perspective view of a space dividing system embodying the present invention with a portion of the divider opened as it might be in use and a portion of the divider closed as it would be for storage;

FIG. 2 is an enlarged plan view of two complementary offset mounting brackets on a common post, showing the brackets in a closed position;

FIG. 3 is a side elevation of one of the brackets shown in FIG. 2;

FIG. 4 is an end elevation of the bracket shown in FIG. 3;

FIG. 5 is a perspective view of an extruded snap-on trim element designed to cover a portion of one of the brackets shown in FIGS. 1-4;

FIG. 6 is an enlarged fragmentary side elevation, partially in section, of the end portion of the central supporting structure shown in FIG. 2;

FIG. 7 is a section along line 7--7 in FIG. 6; and

FIG. 8 is a section along line 8-8 in FIG. 7.

While the invention is susceptible of various modifications and alternative forms, certain specific embodiments thereof have been shown by way of example in the drawings which will be described in detail herein. It should be understood, however, that it is not intended to limit the invention to the particular forms disclosed but, on the contrary, the intention is to cover all alternatives, modifications and equivalents falling within the spirit and scope of the invention.

Turning now to the drawings and referring first to FIG. I, there is shown a typical space-dividing arrangement including a series of interconnected space-dividing elements, such as the panels 10 and 11, secured to

complementary offset brackets

20 and 30 which are rotatably mounted to the support posts 40 by

end caps

60 and 61. The space-dividing elements 10 and 11 are fitted with a decorative trim l4, l5, and 16 along the upper and lower surfaces and

channel members

12 and 13, shown most clearly in FIG. 7, extend longitudinally between the panels and the support post 40. In the particular arrangement illustrated in FIG. 1, half of the space-dividing elements are shown extended outward for use as a space divider and the other elements are shown rotated closely parallel to each other, or folded accordian style, for purposes of storage or relocation.

Although FIG. 1 illustrates a divider system having only two space-dividing elements mounted on any one post, one of the important aspects of the present invention is that as many as four elements may be mounted on each post and the system will retain its unique features, i.e., versatility while being adjustable for compact storage. More particularly, an enlarged plan view of support post 40, illustrating four elements in a closed position would be similar to FIG. 2, with two

additional offset brackets

20 and 30, forming a mirror image about center line 70. Thus a system having four elements per post, will fold as compactly as two such systems having two elements per post when folded side by side.

It shouldbe appreciated that more than four brackets may be mounted on any one supporting post if desired. The only physical limitation on the number of brackets used is determined by the segment of arc encompassed by the bracket along the circumference of the post. In the illustrated embodiment, for example, eight brackets each encompassing a 45 arc could be fitted around the supporting post. To form a suitable arrangement it would be preferred to utilize either all left hand brackets or all right hand brackets. In this way the space-dividing elements will all be uniformly spaced at an angle of 45 with respect to each other. It should be understood, however, that when more than four space-dividing elements are positioned around a single post that the resulting divider can no longer be folded" compactly, since the elements cannot all be rotated parallel to each other. It is preferred, therefore, to mount no more than four space-dividing elements on any one support post.

FIG. 2 is a detailed plan view showing one pair of the

complementary offset brackets

20 and 30, illustrated in use. in FIG. 1, in a close parallel position about a common post 40. More particularly, there is a right hand offset bracket 30 and an identical mirror image or left hand ofiset bracket 20. As can be seen most clearly in FIG. 3, each of the

brackets

20 and 30 is generally in the shape of an offset T (as viewed in side elevation) with the long legs 20a and 30a of the T having a pair of

counter sunk holes

22, 23 and 32, 33, respectively, formed therein for fastening the brackets to apair of panels 10 and 11. More particularly, the longer leg 20a of the bracket 20, for example, is placed against the top or bottom edge of the panel and secured thereto by a pair of screws 24, 25 (FIG. 6) inserted through the holes 22, 23 and threaded into the panel material. As can be seen most clearly in FIGS. 3 and 4, the long legs 20a and 30a are also recessed and a pair of

grooves

26 and 27 are formed longitudinally along the bottom surface therein for receiving a decorative trim 50, shown in FIG. 5, for concealing the screws 24, 25 which fasten the bracket to the panel.

In accordance .with one aspect of the invention, the short legs 20b and 30b of the

brackets

20 and 30 are set off at an angle to the long legs 20a and 30a so that the horizontal axis of each space-dividing element is offset with respect to the vertical axis of the support post 40. As will be explained in greater detail below, this feature enables the space-dividing elements and 11 to be rotated closely parallel to each other.

Typically, space-dividing elements are mounted in radial fashion-about the support posts, much like the spokes of a wheel. Panel elements thus mounted are ideally suited for use in a space-dividing arrangement; the full length of the panels can be utilized since they extend directly away from the support posts; the panels can be easily rotated about their axis at the center of the support post; and the angles at which it is .desired to fix the panels in relation to each other can be easily calculated and measured on the basis of a 360 circle. For example, three panels may be symmetrically positioned along a support post at equivalent angles of 120, or at angles of 60, 150 and 150, or at any other preferred combination of 360.

Having a common axis, however, prevents the panel elements from being rotated parallel to each other. This effect is amplified by the fact that the panel elements have dimension. For example, if the width of each bracket projected onto the circumference of the support post consumes a 45 arc, the panels when rotated toward each other will touch when there is a minimum angle between them of 45. While this effect is not particularly significant when the space divider is in use, it makes relocation of the dividing system clumsy and difficult and practically, the divider must be disassembled for storage.

The angle between the short ofiset legs b and 30b and the long legs-20a and 30a offsets the panel elements 10 and 11 with respect to the axis of the support post 40, i.e., the horizontal axes of the space-dividing elements will not intersect at a common position alongthe axis of the support post. Rather the point of intersection between the horizontal axes of any two panels 10 and 11 will change as the panels are rotated with respect to each other and will disappear when the angle between the panels is 0, i.e., when the elements become parallel. It is preferred to design the offset angle in such a way that the panels are parallel to each other when the mounting

brackets

20 and 30 touch along the circumference of the post 40. This allows the panels to occupy theleast amount of space when closed for storage. The offset angle, therefore, must be correlated to exactly offset the minimum angle that would remain if radial brackets were used (see discussion above). In the illustrated embodiment, shown most clearly in FIG. 2, the

offsetbrackets

20 and 30 consume a total are of 90 along the circumference of the post 40. The minimum angle between radial brackets, therefore, would be 45; accordingly, each bracket is off set at an angle of 22.5 to its radial position. The offset angle is illustrated by the angle 0:, shown in FIG. 2. This offset has the effect of bending" the long legs 20a and 30a parallel when the brackets are in a closed position.

It can be seen that as the brackets are rotated relative to each other the radial portion of the bracket will subtend an angle from 45 to 315 while the space-dividing elements will subtendan angle from 0 (parallel) to 270. However, once the absolute value of the angle exceeds 180 it is easily recognized that the relative angle between the space-dividing ele ments will decrease. The effective range of angles between space-dividing elements mounted on radial brackets is, therefore, restricted to the range between 45 and 180, or 135, while the effective range of angles between space-dividing elements mounted on the offset brackets is unrestricted, i.e., the elements may be located at any desired position between 0 and 180. This imparts added versatility in the number of interior space-dividing arrangements possible and permits the space-dividing elements to be rotated close together for convenient storage and easy relocation. It should be appreciated that two or more elements of a room divider may be folded close together even while in use which permits even greater flexibility of use. For example, a room divider as illustrated in FIG. 1 can be shortened" by merely collapsing one end of the divider as shown. This feature eliminates the need to disassemble the room divider for temporary use at a shortened length.

To secure the

channel members

12 and 13 to the elements 10 and l 1, the long legs 20a and 30a of the

brackets

20 and 30 are positioned on the panels 10 and 11 so that the short cylindrical legs 20c and 30c register with the hollow interiors of

vertical channel members

12 and 13. More particularly, as seen most clearly in FIG. 7,

channel members

12 and 13 are generally in the shape of hollow right triangular prisms with longitudinal flanges forming a groove that overlaps and extends the full vertical length of the panels 10 and 11. The short

cylindrical legs

20c and 300 of the

brackets

20 and 30 fit snugly into the inner triangular circumferencesof the

channel members

12 and 13, and in coordination with the flanges of the channel members, hold the channel members securely to the panels 10 and 11 without the use of screws or additional restraints of any kind. This particular arrangement causes the common post 40 to fit closely tangential along a longitudinal line on the inner exterior surface of said

channel members

12 and 13. In keeping with one aspect of the present invention, this effectively blocks the view between the common post 40 and the vertical edges of the panels 10 and 11. More particularly, even the point of contact between said common post and said channel members is effectively hidden from view by the outer exterior surface of said channel members and by the curvature of said common post.

To pivotally mount the

brackets

20 and 30 on the central supporting post 40, a pair of

end caps

60 and 61 are fitted over either end of the post to receive the short offset legs 20b and 30b of the offset-T shaped brackets. As shown most clearly in FIG. 6, each of the end caps 60 and 61 includes a first annular section 60b adapted to slide into the post 40, and a second annular section 60a adapted to slide over the post 40. The inner portion of annular section 60a forms an annular channel 63 which receives the upwardly extending legs of the offset

brackets

20 and 30 which are complementally formed with respect to the post 40 so that the

brackets

20 and 30 may swivel around the post 40 within the annular channel 63. The end caps 60 and 61 are held stationary on the post by a single set screw 62 which does not interfere with the movement of the offset

brackets

20 and 30 around the annular channel 63.

The illustrated embodiment shown in FIGS. 1, 6 and 8 utilizing

end caps

60 and 61, is intended only as an illustration of one means of securing the offset brackets to the support posts, for example for use in a folding" space divider as illustrated in FIG. 1. In this connection it should be appreciated that the offset brackets may be used in conjunction with the space-dividing arrangement described in U.S. Pat. No. 3,559,352. In such case the offset brackets may be mounted to the support posts to permit adjustment of the brackets along the vertical axis and to accommodate space'dividing elements of varying dimensions.
