The locking arm pedestal system includes a clevis assembly pivotally attached to a plurality of pivotal arms. One of the arms is pivotally attached to a telescoping arm housed in a base, the telescoping arm setting the desired height of the clevis assembly. The base is adapted to be mounted to a vehicle console and floor. The clevis assembly includes a pivotal mounting bracket where an item can be mounted thereon at a desired angle. A pivot locking joint prevents the mounting bracket from pivoting from the desired angle. Each of the pivotal arms also includes similarly configured pivot locking joints to set the desired position of the clevis assembly with respect to the user. Fasteners clamp the locking pivot joints in place.
Description
- 1. Field of the Invention
- The present invention relates to mounting systems, more specifically, to a locking arm pedestal system for supporting items thereon in a stable and safe manner.
- 2. Description of the Related Art
- Many commercial and government vehicles, as well as some private ones, employ some sort of mounting system to support various items such as laptops. The mounting system allows for ergonomic, ready access to the item without having to juggle the same on the user's lap or to search through bags or storage in other parts of the vehicle. While convenient, these mounting systems can be a safety concern.
- For example, during everyday use of a vehicle with the typical mounting system installed, the user may experience occasional traffic related incidences such as sudden deceleration, abrupt bumps or accidents. When that occurs, extreme forces are acting upon the item mounted on the mounting system due to the momentum of the vehicle. A typical mounting system includes at least one articulating arm and mounting bracket that can be adjustably positioned by the user where the user can have easy access to the item or laptop mounted at one end of the arm. The other end is pivotally attached to a base. The adjusted positions of the mounting bracket and arm are usually set by simple screw clamps at the pivot joints. As a result, any changes in momentum of the vehicle transfers those forces to the pivot joints where, over time, the clamped engagement can potentially loosen. If the user inadvertently fails to address this potential hazard, the next incidence of momentum change may cause the item to swing about and hit the driver or the interior of the vehicle resulting in an accident. In light of the above, it would be a benefit in the art of mounting systems to provide a safer configuration that substantially reduces the chances of loosened pivots.
- Thus, a locking arm pedestal system solving the aforementioned problems is desired.
- The locking arm pedestal system includes a clevis assembly pivotally attached to a plurality of pivotal arms. One of the arms is pivotally attached to a telescoping arm housed in a base, the telescoping arm setting the desired height of the clevis assembly. The base is adapted to be mounted to a vehicle console and floor. The clevis assembly includes a pivotable mounting bracket where an item can be mounted thereon at a desired angle. A pivot locking joint prevents the mounting bracket from pivoting from the desired angle. Each of the pivotal arms also includes similarly configured pivot locking joints to set the desired position of the clevis assembly with respect to the user. Fasteners clamp the pivot locking joints in place.
- These and other features of the present invention will become readily apparent upon further review of the following specification and drawings.

FIG. 2 is an exploded view of the position setting assembly in the locking arm pedestal system according to the present invention. -
FIG. 3 is an exploded view of the clevis assembly in the locking arm pedestal system according to the present invention. -
FIG. 4 is a perspective view of the lower bracket in the clevis assembly for the locking arm pedestal system according to the present invention. - Similar reference characters denote corresponding features consistently throughout the attached drawings.
- The present invention relates to a locking arm pedestal system, generally referred to by
reference number 10 in the drawings, that locks pivot connections to prevent hazardous undesirable movement of parts. As shown inFIGS. 1 and 2 , the lockingarm pedestal system 10 includes apositioning assembly 20 mounted to a base 12. The base 12 includes abase mounting bracket 14 from which a support pole, bar orarm 16 extends. Thebase mounting bracket 14 may be a substantially flat plate with a plurality of mounting holes andslots 15 disposed thereon to facilitate mounting the lockingarm pedestal system 10 onto the floorboard of a vehicle or other foundation. Thesupport pole 16 may be a hollow, tubular member that slidably supports the extendable pole, bar orarm 24 housed therein. A plurality oflateral mount brackets 18 withcorresponding mounting holes 19 may be disposed at intervals along the length of thesupport pole 16 so as to provide lateral support for the lockingarm pedestal system 10 when installed, e.g., onto a side of a central console in a vehicle. - The
positioning assembly 20 includes an extendable or telescopingpole 24,first positioning arm 40,second positioning arm 50 and aclevis assembly 60 adjustably mounted to one end of thesecond positioning arm 50. Theextendable pole 24 sets the desired elevation or height while the first andsecond arms clevis assembly 60. - To set the height of the
positioning assembly 20, as shown byarrow 21, theextendable pole 24 may be a cylindrical tube having alocking rod 28 slidably disposed within the hollow interior with alocking slot 26 formed on a side of theextendable pole 24. Thelocking slot 26 exposes or allows access to thelocking rod 28. When the desired elevation has been reached, the user tightens thehandle 22 whereupon a corresponding end of thehandle 22 clamps thelocking rod 28 and thereby theextendable pole 24 into place. Other clamping assemblies may be employed in place of thehandle 22 such as a cam lock. - As shown in
FIG. 2 , thelocking rod 28 may be an elongate, round bar having threaded ends. One of the threaded ends is attached to abar wedge 34 while the other end is attached to aclamping knob 30 clamping thefirst positioning arm 40 therebetween. With this configuration, thelocking rod 28 serves two purposes. Besides helping to set the height of thepositioning assembly 20, thelocking rod 28 also permits adjustable repositioning of thefirst positioning arm 40. The lower end of theextendable pole 24 includes a beveled edge. Accordingly, thebar wedge 34 includes a mating beveled edge. When assembled with thefirst positioning arm 40, thebar wedge 34 allows reciprocating movement of thelocking rod 28 whenever theclamping knob 30 is loosened but prevents thelocking rod 28 from rotating because of the interfering beveled edges between thebar wedge 34 and theextendable pole 24, i.e., thebar wedge 34 forms a base that maintains thelocking rod 28 in a stationary position with respect to thesupport pole 16 such that repositioning of thefirst locking arm 40 may be facilitated. - Once the height has been set, the first and second positioning
arms FIG. 2 , thefirst positioning arm 40 may be an elongate, channeled plate 44 having bores at opposite ends. Thebore 43 extends through abushing 42 extending downwardly or depending from the bottom of the plate 44. Thebushing 42 is adjustably mounted over the upper end of theextendable pole 24 in the adjustable directions indicated byarrow 41 by loosening theknob 30 to allow rotated repositioning of thefirst arm 40. One of the threaded ends of thelocking rod 28 extends through thebore 43, and theclamping knob 30 firmly fixes the rotated or pivoted position of thefirst positioning arm 40. - The clamping engagement via the
knob 30 is not enough to minimize unwanted and potentially dangerous movement of thefirst positioning arm 40 whenever abrupt forces are acting thereon. To minimize this possibility, the lockingarm pedestal system 10 includes pivot locking connections or joints. The pivot locking connection between thefirst positioning arm 40 and theextendable bar 24 includes a toothed male locking member orspline 32 and a corresponding female locking member or spline within the bushing 42 (not shown but similar to the female spline 46), the female locking member having a corresponding recess with a tooth configuration matching that of themale spline 32. The mating tooth configuration between themale spline 32 and the female spline within the bushing 42 prevents any rotation of thefirst positioning arm 40 with respect to theextendable arm 24 once assembled and clamped. Thus, the adjusted rotated position of thefirst positioning arm 40 is locked. - The
second positioning arm 50 is rotatably or pivotally mounted to thefirst positioning arm 40 at the opposite end of thefirst arm 40 from thebore 43. Thesecond positioning arm 50 is similar to thefirst positioning arm 40 in that thesecond arm 50 may also be an elongate, channeledplate 54 having bores at opposite ends. Thesecond positioning arm 50 also includes a pivot locking connection between thefirst positioning arm 40 and thesecond positioning arm 50 via the recessed toothed female locking member orspline 46 and a corresponding toothed male locking member orspline 56 at the bottom of the channeledplate 54. A threaded fastener 52 extends through the bore in the male andfemale splines bushing 47 where another clampingknob 49 connects to the fastener 52 to set the rotated position between thearms arrow 51. The clampingknob 49 may be biased by aspring 48 to help prevent separation between thearms knob 49 is loosened. - The
clevis assembly 60 is rotatably attached to the other end of thesecond positioning arm 50 by fasteners such as abolt 69,nut 71 andwashers arrow 51. As shown inFIGS. 3 and 4 , theclevis assembly 60 includes anupper mounting bracket 62 pivotally attached to alower mounting bracket 90. The pivotable upper mountingbracket 62 permits the user to set the angular disposition of the item A with respect to the user as indicated byarrow 63. Theupper mounting bracket 62 may be substantially U-shaped with extensions orlegs bracket 62 includes various mountingslots 64 to mount an item A thereon, such as a laptop. The item A would typically be attached to the upper mountingbracket 62 via a separate bracket, and thevarious slots 64 accommodates mounting of a wide range of brackets. Thelower mounting bracket 90 is similarly configured as aU-shaped plate 97 having extensions orlegs central bore 91 on theplate 97 facilitates mounting of thelower bracket 90 to the end of thesecond positioning arm 50. It is noted that a locking pivot connection is not included between thelower bracket 90 and thesecond positioning arm 50 because disturbances would not cause the item A to swing. At most if the connection is loose, the item A would rotate about thefastener 69. However, this pivot connection may also include a locking pivot similar to the ones between the first andsecond arms - As with the first and
second positioning arms clevis assembly 60 also includes a pivot locking connection. In that regard, the locking pivot connection of theclevis assembly 60 includes a toothed male locking member orspline 70 on the interior of theleg 66 that seats within the toothed female locking member orspline 92 on the exterior of theleg 96. The matingmale teeth 75 and thefemale teeth 95 prevents pivoting or rotation of the upper mountingbracket 62 once the angular position has been set. - The upper and
lower brackets pivot pin 74 extending through thebores 73 in theupper bracket 62, anintermediate sleeve 78, and thebores pivot pin 74 may be threaded at one end while the other end includes a square shapedhead 76. Thehead 76 engages a correspondingly shaped bore 73 to keep thepin 74 stationary and prevent relative rotation thereof. The threaded end connects to a clampingknob 82 to set the pivoted position of theupper bracket 62. Since wear and tear as well as the weight of the object or item A creates stresses at the pivot, theclevis assembly 60 also includes atension spring 80 surrounding thesleeve 78 to ensure a tight clamping engagement between the extensions in the respective legs of the upper andlower brackets - Thus, it can be seen that the locking
arm pedestal system 10 includes enhanced safety features. The locking pivot connections ensure that the articulated elements stay in the adjusted position, especially in situations where abrupt forces are acting thereon. Moreover, thearms clevis assembly 60 are easily adjusted by loosening the corresponding clamping knobs 30, 49, 82 to allow the toothed connection to be disengaged. - It is to be understood that the locking arm pedestal assembly encompasses a variety of alternatives. For example, the pivot locking connections can include radiating teeth instead of the teeth at the edges. Various shapes and numbers of teeth may be used depending on the degree and ease of adjustments desired. Moreover, selectively engageable detents may also be viable alternatives.
- It is to be understood that the present invention is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims.
