FIELD OF THE INVENTION
The present invention relates generally to vehicle barrier systems and, in particular, to an illuminated gate arm with telescopic extensions that facilitates storage, shipping and installation.
BACKGROUND OF THE INVENTION
Traffic or vehicle barriers are used to provide controlled access of vehicle traffic to restricted areas, such as private “gated” communities, parking lots, parking garages, loading docks, and controlling the flow of traffic on roads, and so forth. Of primary concern is the use of a gate arm that is maintained in a horizontal position to impede vehicle passage and operatively pivoted into a vertical position to allow vehicle passage. For instance, gated communities use a gate arm to stop unauthorized access to the community. Gate arms consist of an arm made of wood or aluminum and are easily recognized during the day, as compared to at night. For distance viewing, the gate arm may include a bright color scheme and/or reflective tape. The reflective tape or bright color scheme tends to fade over time and is often covered with debris, causing limited visibility at night.
To address the limitations of visibility, gate arms include a lighting assembly attached to the gate arm. Modern lighting assemblies employ a gate arm formed from a lightweight elongated piece of aluminum material having a control system to selectively pivot the gate arm between a horizontal position and a vertical position. The aluminum material is extruded to include an inset channel for receipt of a removable LED light strip. Recognized modern extruded aluminum gate arms having an inset channel are disclosed in U.S. Pat. Nos. 8,845,125; 9,157,200; and 9,273,435.
Gate arms are extruded in different lengths. For instance, a narrow roadway entrance may use a 7 ft. long gate arm. A wider roadway may use a 17 ft. long gate arm or any length therebetween. Shipping a 7 ft. long gate arm is cost effective and manageable. Shipping a 17 ft. long gate arm requires a special carrier and is extremely expensive, with the cost of shipping typically costing more than the gate arm. The companies capable of transporting long items are more difficult to engage, as a long gate arm consumes a large floor space.
While a modern aluminum extruded gate arm is strong, it is not indestructible. Impacting the gate arm at the wrong place can result in damaging the cosmetic appearance. For this reason, the gate arm may be wrapped in shipping material. Further, if the impact is severe, the gate arm could be bent. If such a possibility exists, then the gate arm would be placed in a crate capable of protecting the gate arm.
Unique to this invention is the nesting of multiple gate arms wherein storage and shipping of the gate arms is reduced to the size of a single gate arm. The problem with the prior art, to which this invention addresses, is that the storage and shipping of gate arms over 8 ft. in length limits the carriers capable of transporting the arms, and exponentially increases the cost of storage and shipping. For instance, a 17 ft. gate arm must be properly crated to avoid damage during storage and shipping. The length is unwieldy to move and even though a long gate arm is light, it is not something a sole individual can be entrusted to carry without risking damage to the gate arm or surrounding area, or to the individual. The crating of the gate arm adds weight and bulk, wherein multiple individuals or a lift truck may be needed to move the gate arm. Further, fixed length gate arms must be sized for the opening. For instance, a roadway can easily range from 7 ft. wide to 17 ft. wide. An installer may have to cut a gate arm during installation to meet the opening. However, cutting of the gate arm can result in sharp edges or expedite corrosion. For example, an installer having a 15 ft. opening needs to either order that length or cut a longer length to size. If the gate arm is constructed from anodized aluminum, cutting of the gate arm exposes the metal. Further, the cut will need to be deburred after the cut to avoid sharp edges.
What is lacking in the art is a gate arm that is telescopic from 7 ft. to at least 15 ft., and can be transported by any shipping company.
SUMMARY OF THE INVENTION
The present invention overcomes the deficiencies of the known art and the problems that remain unsolved by providing a gate arm that can be stored and shipped in a first length, and expanded to a length as needed upon installation. In a preferred embodiment, the base gate arm is 7 ft. long having a first extension insert sufficient to add 5 ft. of length to the base gate arm, and a second telescopic insert sufficient to add another 5 ft. of length to the base gate arm, to obtain an overall length of 17 ft. The telescopic gate arm employs a controller adapted to pivot the gate arm between a horizontal position and a vertical position to control the flow of vehicle traffic. The gate arm and individual telescopic arms include inset channels for removeably receiving an array of LED lights to increase visibility and alert drivers or pedestrians to the presence of the gate arm at night.
In accordance with one implementation of the present invention, there is provided a vehicle barrier system comprising: a first gate arm having a first continuous side wall forming a cavity therein, the first side wall including a first elongated inset channel having an opening formed along a longitudinal axis of the first gate arm; a second gate arm having a second continuous side wall slidably insertable into the first cavity of the first gate arm, the second continuous side wall forming a second cavity therein, the second side wall including a second elongated inset channel having an opening formed along a longitudinal axis of the second gate arm; a third gate arm having a third continuous side wall slidably insertable into the second cavity of the second gate arm, the third side wall including a second elongated inset channel having an opening formed along a longitudinal axis of the second gate arm; and a light strip removably retained within the elongated inset channel of the first, second and third gate arms such that light from the light strip is visible through the inset channel. The light strip can be cut to size as necessary wherein the length of the gate arm can be adjusted on site to a particular length.
An objective of the invention is to provide an telescopic lighted gate arm, namely a gate arm that can expand in length from 7 ft. to 17 ft., wherein an installer may customize the length to meet a particular installation limitation.
Yet another objective of the invention is to teach the use of nesting gate arms to minimize storage requirements and shipping costs, wherein a first gate arm forms a cavity for receipt of a second gate arm, and the second gate arm forms a cavity for receipt of a third gate arm.
Yet still another objective of the invention is to provide a light strip formed from a plurality of light emitting diodes, each electrically connected in parallel, encased within a protective member, for slidable insertion through slots in adjoining gate arms to provide continuity between gate arm inset channels.
Another objective is to provide an octagon gate arm having a front surface and rear surface on each side of an inset channel for receipt of a reflective tape or coating.
Yet still another objective of the invention is to employ spacing tabs to allow ease of gate arm insertion and removal from a cavity while protecting the tape or coating placed on the inset channel top surface.
Another objective of the invention is to provide an inset channel guarded by at least one terminating end to assist in retaining of a light strip.
Still another objective of the invention is to provide a collapsible gate arm assembly that can be stored in a smaller length for less wind exposure during high winds, such as hurricanes.

DETAILED DESCRIPTION OF THE INVENTION
Detailed embodiments of the instant invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, specific functional and structural details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representation basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure. The present invention is directed to a vehicle barrier system comprising an telescopic gate arm 10 for use in providing controlled access of vehicle traffic in particular designated areas including, but not limited to, parking lots, parking garages, loading docks, highways, military bases, airports, roadways, or the like. It will be understood that the barrier system 10 of the present invention may be modified slightly to provide a barrier system for use in providing controlled access of individuals or pedestrian traffic in or out of various designated areas including, but not limited to, buildings, walkways, bridges, tunnels, or other areas where controlled access to individuals is contemplated.
With reference made to FIGS. 1A-1B and 2, the telescopic gate arm 10 of the instant invention consists of a base arm 12, an extension arm 14, and an end arm 16. The telescopic gate arm 10 is deployed along a designated roadway 200 to facilitate controlled access of vehicles 210 in restricted areas, such as gated communities. Control of the telescopic gate arm 10 includes a controller 20 that allows the movement of the telescopic gate arm 10 to pivot between a guarded position as depicted in FIGS. 1A-1B, and an unguarded position as depicted in FIG. 2, thereby limiting the passage of vehicles 210 to enter or exit the private area while the gate arm 10 is in the horizontal guarded position. The controller 20 is secured to a post 22, which in turn is mounted to the ground using a cement foundation 24. For installation purposes, the height of the mounting post 22 is selected to align the telescopic gate arm 10 above the surface of the roadway 200, such that the gate arm 10 spans the width of the roadway 200 to prevent passage of vehicles when the gate arm 10 is in the horizontal guarded position.
The controller 20 is used to pivot the telescopic gate arm 10 from the horizontal guarded position to a vertical unguarded position to control traffic through a roadway. The controller 20 is well known in the art, and consists of an electrical motor coupled to a gearing system, such as a variable frequency drive, to operate the speed and torque of the motor. Alternatively, a control system may include a pneumatic system or hydraulic system including an air compressor, a hydraulic pump, fluid motors, pneumatic or hydraulic cylinders, electrical limit switches, valves, filters, couplings, regulators, and hoses or pipes, where such components are operatively coupled together to control the pivoting movement of the telescopic gate arm. In yet another embodiment, the telescopic gate arm may include a spring-balanced system, not shown, wherein a spring tension holds the security gate arm in an upright vertical position, until pushed downwardly by force. An internal spring counter balancing weight may be included to allow easy lifting and lowering of the gate arm.

A third chamfer wall 150 is angled 45 degrees from the second rear wall 142 to a second side wall 152. A fourth chamfer wall 154 is angled 45 degrees from the second side wall 152 to the first front wall 122.
Similar to the extension arm 14, a first spacer tab 119 is positioned on the outer edge of the first front wall 120 of the end arm 16; a second spacer tab 121 is positioned on the outer edge of the second front wall 122. A third spacer tab 139 is positioned on the outer edge of the first rear wall 140, and a fourth spacer tab 141 is positioned on the outer edge of the second rear wall 142. The spacer tabs positioned along the end arm 16 are constructed and arranged to slide within the extension arm 14 so as to center the end arm 16 in relation to the inner surface of the extension arm 14. The centering of the extension arm 14 protects the outer surfaces of the arm from scratching during storage, shipping and installation. This allows the factory placement of reflective tape or paint on the first and second front walls 120, 122, and the first and second rear walls 139, 141.
Referring to FIG. 7, illustrated is an elongated inset channel 44 having an opening 48 formed by a pair of inset channel sidewalls 131, 133 integrally joined to a channel backwall 135. The inset channel walls 131, 133, including at least one terminating end 137 spaced from a sidewall 133 to form the opening 48. For ease of drawing readability, a single inset channel has been numbered, but it will be understood that all the inset channels for each arm are uniform. It is further noted that the terminating end 137 may extend from side wall 131, or extend from both channel sidewalls 131 and 133. For rigidity purposes, the backwall 147 of the end arm 16 operates for the front inset channel 124 and the rear inset channel 144.
Referring to FIGS. 8-10, depicted are the base arm 12 and extension arm 14 having inset channels 44, 82 shown along axis 157). A slot 149 is placed along the inset channel 82 of the extension arm 14; similarly, an identical slot 149 is placed along the inset channel 124 of the end arm 16. For ease of drawing description, it is noted that the slots may be placed anywhere along the length of the arm 14, 16 as well as on the rear facing inset channels. The slots allow the placement of a strip of light emitting diodes 150 to be inserted within an inset channel, wherein the LED strip 150 is cradled within the channel sidewalls of the inset channel. The terminating end of each inset channel retains the LED strip within the inset channel, thus eliminating the need for fasteners and allowing quick and easy installation or removal of the LED strip 150. The LED strip 150 is positioned within each inset channel such that light, illuminated from the light emitting diodes, passes through the opening of the inset channel.
In a preferred embodiment, the LED strip 150 is preferably enclosed within a protective enclosure or shock absorbing protective substrate. The protective substrate may comprise any of a transparent rubber, a clear hardened gel material, a clear epoxy, a clear vinyl, or a clear resin material. In one embodiment, each of the plurality of light emitting diodes 150 comprises the same color; however, each of the light emitting diodes 150 may comprise multiple sets of different colors, where a number of light emitting diodes comprise one color, and an N number of light emitting diodes comprise another color. This allows illumination of a red color when the gate arm is in a horizontal position, and a green color when the gate arm is in a vertical position. In a preferred embodiment, the light emitting diodes are coupled to a high-intensity LED flasher unit capable of outputting a luminescence at about 60 flashes per minute.
A fastener 160 is used to fix the extended length of the gate arms. The fastener 160 can be a screw or, more preferably a spring loaded detent, wherein the extension arm 14 and end arm 16 can be adjusted to a particular length. It should be noted that the fastener 160 will allow the extension arm 14 and end arm 16 to be reinserted into the base arm 12. This would protect the gate arm during high winds such as hurricanes.

The term “coupled” is defined as connected, although not necessarily directly, and not necessarily mechanically. The use of the word “a” or “an” when used in conjunction with the term “comprising” in the claims and/or the specification may mean “one,” but it is also consistent with the meaning of “one or more” or “at least one.” The term “about” means, in general, the stated value plus or minus 5%. The use of the term “or” in the claims is used to mean “and/or” unless explicitly indicated to refer to alternatives only or the alternative are mutually exclusive, although the disclosure supports a definition that refers to only alternatives and “and/or.”
The terms “comprise” (and any form of comprise, such as “comprises” and “comprising”), “have” (and any form of have, such as “has” and “having”), “include” (and any form of include, such as “includes” and “including”) and “contain” (and any form of contain, such as “contains” and “containing”) are open-ended linking verbs. As a result, a method or device that “comprises,” “has,” “includes” or “contains” one or more steps or elements, possesses those one or more elements, but is not limited to possessing only those one or more elements. Furthermore, a device or structure that is configured in a certain way is configured in at least that way, but may also be configured in ways that are not listed.
It is to be understood that while a certain form of the invention is illustrated, it is not to be limited to the specific form or arrangement herein described and shown. It will be apparent to those skilled in the art that various changes may be made without departing from the scope of the invention and the invention is not to be considered limited to what is shown and described in the specification and any drawings/figures included herein.
