Description:
BACKGROUND OF THE INVENTION 
   The present invention relates to brackets and inserts for coupling a mountable device to a mounting pole. 
   Mounting brackets are typically used to affix mountable devices to mounting poles. Conventionally, when a device, such as a video display, computer terminal, video camera, scoreboard, etc., must be visible from a distance or from a certain vantage point, it is mounted to a mounting pole. This allows the device to use less floor or desk space, and also allows the device to be raised to a higher position, thus allowing for greater visibility. 
   Usually, coupling a mountable device to a mounting pole requires the use of a mounting bracket. The mounting bracket conventionally attaches to the mounting pole at one end and to the mountable device at the opposite end. See U.S. Pat. No. 6,499,704. 
   While conventional mounting brackets function as designed, in order to get and maintain a tight grip on the mounting pole, a conventional mounting bracket is physically tightened about and in direct contact with the mounting pole. This direct contact between the mounting bracket and mounting pole often leads to scratching, stripping or deformation to either the mounting pole, mounting bracket or both. In addition, mounting brackets may also cause the gouging of a channel or deep scratch on the surface of the mounting pole. These channels or deep scratches further loosen the mounting bracket and ultimately may cause the bracket and/or mounting pole to need replacement, which also increases costs. 
   Additionally, over time, an originally tight mounting bracket-mounting pole interconnection may loosen, thereby allowing the mountable device to move from its preferred position. 
   While mounting brackets are typically made for use with a range of mounting pole sizes, these sizes are necessarily limited to a range of mounting pole sizes due to the size of the mounting bracket itself. 
   Although mounting brackets are available for purchase in numerous sizes, a change from one mounting pole diameter to another generally requires the purchase of a mounting bracket of a suitable size. It is thus expensive to change the size of a mounting bracket.

   DETAILED DESCRIPTION 
   The present invention advantageously provides a mounting bracket and insert that together allow the secure coupling of a mountable device assembly to a mounting pole. 
   It also advantageously allows for the bracket to tightly grip the mounting pole without damage resulting to either the bracket or to the mounting pole. Instead, a generally less expensive insert is used between the bracket and the mounting pole to moderate the potential damage to the mounting pole or bracket, and to prevent slippage of either. 
   Additionally, due to the tight grip the bracket and insert can have on the mounting pole, the mountable device so mounted is securely in a fixed position and less likely to move due to slippage at the bracket/insert-mounting pole coupling. 
   The present invention also advantageously provides for a single bracket size to accommodate mounting poles of different diameter and geometry. When a bracket is overly large for the mounting pole in use, instead of changing brackets, the present invention allows the use of a thicker bracket insert, having a smaller inner diameter or geometry. Thus, the same size bracket may be used with a diverse assortment of sizes and shapes of mounting poles. Changing the bracket insert may be significantly less expensive than changing the bracket itself. 
     FIG. 1  illustrates a mounting bracket and insert assembly according to an embodiment of the present invention. In a preferred form, and as illustrated in  FIG. 1 , the mounting bracket and insert assembly  100  may be used to affix a mountable device (not depicted in  FIG. 1 ) to a mounting pole (also not depicted in  FIG. 1 ). In an embodiment, the mounting bracket may be formed by an aluminum extrusion process, although any material and method of production may alternatively be used. 
   Preferably, the mounting bracket comprises two unconnected sections, herein identified as bracket sections  110  and  120 . The two bracket sections  110 ,  120  preferably mate to enclose a mounting pole between them. Alternatively, a bracket using a hinge to join the two sections, thereby allowing the enclosure of a mounting pole, may be used. Additionally, more than two bracket sections may be employed in a mounting bracket to form the enclosure around a mounting pole. 
   Regardless of the number of bracket sections  110 ,  120  used, at least one of the bracket sections  110  preferably includes a mountable device support area  116  adapted to support or attach to a mountable device. This mountable device support area  116  may be an integral part of the bracket section  110 , or may be a separate unit attached with one or more fasteners (not depicted). The mountable device support area illustrated in  FIG. 1  is exemplary of an integral mountable device support area. 
   The mountable device support area  116  depicted in  FIG. 1  includes a cylindrical mounting bore  111  adapted to receive a bushing  150 . The bushing  150  may optionally receive a rod for mounting a display device.  FIG. 1  shows a bushing  150  having a cylindrical section  151  sized to be inserted into the cylindrical mounting bore  111 . A lip  152  extends beyond the diameter of the cylindrical section  151  at the upper distal portion of the bushing  150  to prevent the bushing  150  from passing completely through the cylindrical mounting bore  111  under the weight of an attached mountable device (not depicted). 
   The bushing  150  may be used for rotationally attaching a mountable device to the mounting bracket. A mountable device can be attached to the cylindrical mounting bore  111  of the mounting bracket and insert  100  using other assemblies. Also, the mounting bore  111  does not necessarily need to be cylindrical, but may be of any shape or construction. The bushing  150  should be modified to accommodate the dimensions of the mounting bore  111 . For example, if a mounting bore  111  with a rectangular cross-section is employed, the bushing  150  may include a section  151  with a rectangular, rather than a cylindrical cross-section. In such an embodiment, the bushing  150  may include a cylindrically bored inner area to provide a swivel capability to the attached display monitor, or the swivel capability would be provided at a locus other than the bushing  150 -mounting bore  111  interface. 
   Similarly, the mountable device support area  116  of the bracket section  110  may support a mountable device using any of several alternative mechanisms. For example, the mountable device support area  116  may itself be an integral part of the frame of the mountable device. Alternatively, additional supporting structures (not depicted) may be attached to the mountable device support area  116 , either removeably or permanently, with one or more display monitors attached thereto. 
   As previously mentioned, the mounting bracket preferably comprises two sections, herein identified as sections  110  and  120 . The two bracket sections  110 ,  120  preferably mate so that their interior surfaces  112 ,  122  enclose bracket inserts  130 ,  140 , which, in turn, enclose a mounting pole between them. Alternatively, when a different number of bracket sections are employed, their interior surfaces would preferably mate to enclose bracket inserts  130 ,  140 , and a mounting pole. While the mounting pole is often cylindrical, it may be of any size or cross-sectional shape. The interior surfaces  112 ,  122  of the two bracket sections  110 ,  120  should preferably be adapted to approximate the size and cross-section of the mounting pole, also taking into account the size and shape of the bracket inserts  130 ,  140 , which are disposed therebetween. 
   The two bracket sections  110 ,  120  preferably mate to each other using socket head capscrews  128  or other fasteners that allow adjustment of the mating tightness. A tightening of the fasteners preferably decreases the distance between the bracket sections  110 ,  120 , thereby tightening the grip of the bracket on the bracket inserts  130 ,  140  and the mounting pole between the inserts  130 ,  140 . The bracket sections  110 ,  120  illustrated in  FIG. 1  include threaded holes  117  bored in flanged areas  113  of bracket section  110 , which are in alignment with countersunk holes  127  bored in corresponding flanged areas (not depicted) of bracket section  120 . Socket head capscrews  128  with head diameters greater than the countersunk holes  127  are passed through the countersunk holes  127  and the threaded holes  117 , thereby mating the two bracket sections  110 ,  120  together. 
   Of course, other means of fastening the two bracket sections  110 ,  120  together may be used. For example, the two bracket sections  110 ,  120  may be hinged together along corresponding edges  129 , with the holes and socket head capscrews or other threaded fasteners described above used only on the opposing flanged areas  113 . Alternatively, other fasteners may be employed, such as threaded bolts. These other useable fasteners include but are not limited to: wingnuts, screws, latches, nut-bolt combinations, fastening pins, and equivalents thereof. 
   Preferably, and as illustrated in  FIG. 1 , the two bracket sections  110 ,  120  mate so that their inner concave surfaces  112 ,  122  enclose bracket inserts  130 ,  140 , which, in turn, enclose a mounting pole between them. The inner concave surfaces  112 ,  122  of the bracket sections  110 ,  120  may also include one or more grooves  114  aligned in the same direction as the major axis of the mounting pole, also referred to herein as the “longitudinal axis”  101 . The one or more grooves  114  on the inner concave surfaces  112 ,  122  of the bracket sections  110 ,  120  each correspond to longitudinal rib protrusions  132 ,  142  on the exterior faces  143  of the bracket inserts  130 ,  140 . The rib protrusions  132 ,  142  are sized and positioned to allow the bracket inserts to be slid onto the inner concave surfaces  112 ,  122  of the bracket sections  110 ,  120 , thereby mating the bracket inserts  130 ,  140  to the corresponding bracket sections  110 ,  120 . 
   In a preferred embodiment, the grooves  114  on the inner concave surfaces  112 ,  122  of the bracket sections  110 ,  120  and their corresponding longitudinal rib protrusions  132 ,  142  on the exterior faces  143  of the bracket inserts  130 ,  140  have a cross-section  115  whereby the groves  114  and protrusions  132 ,  142  are narrower where they join to meet the inner concave surfaces  112 ,  122  of the bracket sections and exterior faces  143  of the bracket inserts, respectively, and wider in the more distal portions. This cross-section causes the joint between the bracket sections  110 ,  120  and bracket inserts  130 ,  140  to remain more securely in place, reducing the freedom of movement of the bracket inserts  130 ,  140  relative to the bracket sections  110 ,  120 . 
   The bracket inserts  130 ,  140  also each have an inner concave surface  131 . The inner concave surfaces  131  are directly in contact with a mounting pole in an embodiment. Although  FIG. 1  depicts the inner concave surfaces  131  as smooth, as illustrated in  FIG. 2  the inner concave surfaces  231 ,  241  may alternatively be ribbed. They may also have any manner of surface (e.g., ribbed, rough, dotted, dimpled, etc.), which serves to protect and grip the mounting pole. 
   The bracket inserts  130 ,  140  are preferably composed of a pliable material, such as plastic or rubber, most preferably a polyvinyl chloride (“PVC”). Some embodiments may alternatively use a material with less flexibility and more rigidity, such as vinyl or cardboard. Other materials may alternatively be employed. 
     FIG. 2   a  illustrates a pair of bracket inserts  200  in accordance with an embodiment of the present invention. The bracket inserts  200  have an exterior surface  243  having one or more raised protrusions  242 . The raised protrusions  242  are preferably linear and aligned parallel to the major axis  250  of a cylinder formed by the pair of bracket inserts  200 . The raised protrusions also have a cross-sectional shape  232  that allows insertion of the bracket inserts  200  into the grooves  114  of the inner concave surfaces  112 ,  122  of the two bracket sections  110 ,  120  (visible in  FIG. 1 ). When the raised protrusions are inserted into the grooves  114  of the two bracket sections  110 ,  120 , the groove-protrusion combination preferably serves a locking function, limiting movement of the inserts  200  relative to the bracket sections  110 ,  120 . 
   Although the bracket inserts  200  depicted in  FIG. 2   a  form semi-cylindrical pairs, it should be noted that the number and shape of the bracket inserts  200  may correspond to the number and shape of the bracket sections  110 ,  120 . Thus, an embodiment using a single hinged bracket insert for a bracket using a single hinged bracket section, as well as an embodiment using more than two bracket inserts for a bracket using more than two bracket sections are envisioned. 
   The inner concave surface  231  of the bracket inserts  200  may be smooth or have three-dimensional texturing, such as the ribbing  233  illustrated in  FIG. 2   a . Texturing serves several desirable purposes. A textured inner concave surface  231  may cause less surface area of the bracket insert to actually contact or grip the mounting pole, thereby reducing the area of both exposed to potential damage. Also, extensive texturing such as that illustrated in  FIG. 2   a , when combined with use of a pliable material, such as some plastics, for the bracket inserts  200 , can allow for a longer-lasting tightening of the bracket to the mounting pole due to the anti-deforming forces generated as the bracket is tightened and the ribbing deforms under pressure. If the bracket slightly loosens over time, these anti-deforming forces operate to maintain the pressure and gripping power of the bracket on the mounting pole. “Anti-deforming forces” as used herein means the tendency of a pliable material such as some plastics or rubber to return to their original non-deformed condition once deformed by pressure. Of course, these anti-deforming forces can be eliminated if the material is overly deformed or otherwise loses its structural integrity. 
   The use of a pliable material allows a tight grip of the mounting pole by the mounting bracket-insert combination without many of the disadvantages of prior mounting brackets. For example, the insert greatly reduces the damage to the mounting pole from the mounting bracket, such as scratching or stripping either the mounting pole or the mounting bracket. Most damage likely occurs to the relatively inexpensive insert. 
     FIG. 2   b  is a top plan illustration of an insert  200 ′ according to one embodiment of the present invention. The insert  200 ′ may be formed as a single unit having two or more insert portions  251 ,  252  connected by a hinging area  245 . Each of the insert portions  251 ,  252  may have one or more raised protrusions  232 ′. The insert  200 ′ has an outer surface  243  and an inner surface  231 . In typical use, the inner surface  231  may surround a mounting pole (not depicted) by rotating (“closing”) insert portions  251 ,  252  about hinging area  245 . A hinging area  245  such as that depicted is known as a “living hinge.” This rotation brings insert portion end  254  into a closer proximity with insert portion end  255 , thereby encircling the mounting pole to a greater degree than in the un-rotated (“open”) position. The mounting bracket may then be closed over the insert so that the inner surface of the bracket contacts the outer surface  243  of the insert, and the raised protrusions  232 ′ are inserted into grooves on the bracket. 
   Although  FIG. 2   b  depicts a single-unit insert  200 ′ having two insert portions  251 ,  252 , it is possible to fashion inserts having any number of insert portions. It is also possible that an insert may be used which has only a single unit, wherein the insert ends  254 ,  255  are connected, thereby forming a closed insert ring. This closed insert ring may then be slipped over a mounting pole and tightened into position by surrounding it with the mounting bracket. 
   In another embodiment, as depicted in the top plan illustration of  FIG. 2   c , two mounting bracket sections  261 ,  262  and a pair of inserts  264 ,  265  are shown in assembled relationship about a mounting pole  263 . A mounting pole  263  having a generally square cross section is surrounded by a pair of inserts  264 ,  265 , which, when joined, form an inner region sized and shaped to surround the mounting pole  263 . The outer surface region of the assembled inserts  264 ,  265  are sized and shaped to fit the generally round cross-sectioned inner region formed by the joined bracket sections  261 ,  262 . The bracket sections  261 ,  262  also include grooves  268  into which protrusions  269  from the pair of inserts  264 ,  265  are sized and shaped to fit. The two mounting bracket sections  261 ,  262  may be fastened using fasteners  270 .  FIG. 2   c  depicts an embodiment using inserts  264 ,  265  to couple two mounting bracket sections  261 ,  262  having a generally circular inner cross section when joined with a mounting pole  263  having a generally square cross section. 
     FIG. 2   d  is a top plan illustration of another embodiment in which two mounting bracket sections  281 ,  282  having a generally square inner cross section when joined, such as by fasteners  290 , are coupled to a mounting pole  283  having a generally circular cross section. A pair of inserts  284 ,  285 , which in assembled relation, form a generally circular inner cross section sized and shaped to surround the mounting pole  283 , and having a generally square outer cross section sized and shaped to fit within the inner area of the joined mounting bracket sections  281 ,  282 , is depicted. This embodiment preferably includes grooves  288  on the inner area of the mounting bracket sections  282 ,  282 , and protrusions  289  from the inserts  284 ,  285  sized and shaped to fit the grooves  288 . 
   Although embodiments of square and round cross sectional mounting poles and mounting bracket/insert assemblies are depicted in  FIGS. 2   c  and  2   d , it is understood that any combination of mounting bracket, insert, mounting pole cross sectional geometry may be used. 
   An embodiment of the present invention includes a kit containing a plurality of bracket inserts. The kit preferably includes bracket inserts to accommodate a variety of different sized or shaped mounting poles. For example, each kit may include a collection of bracket inserts designed to fit a predetermined bracket size and shape and a variety of mounting pole sizes. In this example, the outer surfaces  243  of the bracket inserts included in the kit could be of the same dimensions so that all the inserts will accommodate one size of mounting bracket, while the thickness of the bracket inserts and their inner surfaces  231 ,  241  are sized to provide coupling of different sizes or shapes of mounting poles. 
   In another embodiment of the present invention, a kit containing a plurality of bracket inserts and at least one bracket for use with the bracket inserts is provided. 
     FIG. 3  illustrates an embodiment of the mounting bracket and insert in use for holding a mountable device. A mountable device  301  is attached to a mountable device arm  302  by a tilter assembly  198  at one end, while the other end of the mountable device arm  303  is then inserted into a bushing  150 . As described above, the mountable device swivel adapter is seated in bracket section  304 , which is fastened to bracket section  305 . Bracket inserts  306 , only slightly visible in this view, lay between the bracket sections  304 ,  305  and the mounting pole  307 . A mountable device arm  302  and tilter assembly  198  are known from U.S. Pat. Nos. 6,505,988 and 6,409,134. 
   Although the mounting pole  307  is depicted as oriented vertically, a horizontal or diagonal mounting pole  307  may be used in the alternative. If a horizontal or diagonal mounting pole is used, bracket section  304  may be adapted to usably connect with the mountable device arm  303 . This could entail, for example, use of a bracket section  304  having a twist between the interior surface  112  area of the bracket section  304  and the bushing  150 -mounting bore  111  interface area of the bracket section, or by other means. 
     FIG. 4  illustrates a top-down view of a mounting bracket and insert in use for mounting a mountable device to a mounting pole in accordance with an embodiment of the present invention. Again, the mountable device  401  is coupled to a mountable device arm  402  at one end of the mountable device arm  402 , while the other end  403  of the mountable device arm  402  is then inserted into a bushing  150 . As described above, the bushing  150  is seated in bracket section  404 , which is fastened to bracket section  405 . Bracket inserts  406  are visible in profile and lay between the bracket sections  404 ,  405  and the mounting pole  407 . 
   It will be understood that the above-described arrangements of apparatus and the method thereof are merely illustrative of applications of the principles of this invention and many other embodiments and modifications may be made without departing from the spirit and scope of the invention as defined in the claims.
