DETAILED DESCRIPTION OF THE INVENTION

FIG. 1a is a perspective view of a fixture 100 which includes a flexible arm 103, in accordance with the invention. In this embodiment, fixture 100 includes a support structure 101 having a post 102, wherein flexible arm 103 is carried by post 102. Support structure 101 can be of many different types of support structures, but it generally supports flexible arm 103 so it is held at a desired position.

In accordance with the invention, an input device 107 is coupled with post 102 by flexible arm 103. As discussed in more detail with FIGS. 3a and 3b, flexible arm 103 is repeatably moveable between flexed and unflexed positions, so that input device 107 is moveable in response to a force being applied to it. The force can be applied to input device 107 in many different ways, such as by engaging it with a vehicle. Flexible arm 103 allows input device 107 to move when engaged by the vehicle so that it, as well as the vehicle, experience less damage.

Flexible arm 103 can be of many different types, but here it is embodied as a cover 104 that includes a flexible material. The flexible material can be of many different types, such as rubber and plastic. Another embodiment of a flexible arm is discussed in more detail below with FIG. 1b.

Input device 107 can be of many different types, but here it operates as a controller for a moveable vehicle barrier. More information regarding moveable vehicle barriers is provided with FIGS. 5a and 5b. In this embodiment, input device 107 includes a keypad 108 for inputting a security code for operating the moveable vehicle barrier. In this way, input device 107 operates as a security input device. An example of an input device having a keypad is disclosed in U.S. Pat. Nos. 4,728,954 and 5,015,829. An example of an input device having a card reader is disclosed in U.S. Pat. Nos. 4,971,505 and 4,778,324.

In this embodiment, input device 107 includes an outer cover 109 which houses control electronics operatively coupled to keypad 108. Outer cover 109 is attached to flexible arm 103 with brackets and fasteners (not shown). Outer cover 109 and flexible arm 103 are typically hermetically sealed together to restrict the flow of moisture into them. This is useful to protect the electronics and cables housed within cover 109 and flexible arm 103. It should be noted that outer cover 109 and flexible arm 103 are hermetically sealed together when flexible arm 103 is in the flexed and unflexed positions. Further, outer cover 109 and flexible arm 103 are hermetically sealed together when flexible arm 103 moves between the flexed and unflexed positions.

Input device 107 can be in communication with the moveable vehicle barrier in many different ways, such as wirelessly. In this embodiment, however, input device 107 is in wired communication with the moveable vehicle barrier through a cable 106. Cable 106 extends through a channel 105 of flexible arm 103, as well as through post 102. In this way, cable 106 extends through support structure 101. It should be noted that cable 106 generally flows one or more signals. For example, cable 106 can flow an input signal, as well as a power signal for powering input device 107. The input signal controls the operation of the moveable vehicle barrier, so the moveable vehicle barrier allows and restricts access. In this way, fixture 100 provides access control.

FIG. 1b is a partial cut-away side view of a flexible arm 113 which can replace flexible arm 103 of FIG. 1a. In accordance with the invention, flexible arm 113 includes a spring 110 connected between post 102 and input device 107. Spring 110 is repeatably moveable between flexed and unflexed positions so that input device 107 can move in response to applying a force to it. Spring 110 can be of many different types, such as those typically used in garage doors. These types of springs are often referred to as torsion springs and extension springs.

In this embodiment, flexible arm 113 includes a cover 111 which covers spring 110. Cover 111 is repeatably moveable between flexed and unflexed positions in response to spring 110 moving between flexed and unflexed positions. It should be noted that cover 111 can be the same or similar to cover 104 discussed above. It should also be noted that cable 106 (not shown) can extend inside or outside of spring 110. When cable 106 extends inside of spring 110, spring 110 protects it from being damaged. It should also be noted that flexible arms 103 and 113 are more flexible than post 102.

FIG. 2 is a perspective view of a light fixture 120 which includes flexible arm 103, in accordance with the invention. In this embodiment, light fixture 120 includes a support structure 121 having a light post 122 which carries a light 114. Light post 122 holds light 114 above flexible arm 103 so that light 114 operates as an overhead light. Light 114 can be of many different types, but here it includes a cylindrical base 114a which houses a plurality of light emitters 114b. The light emitters can be of many different types, such as incandescent lamps and light emitting diodes.

In accordance with the invention, support structure 121 includes flexible arm 103, wherein flexible arm 103 is carried by light post 122. Further, input device 107 is coupled with light post 122 by flexible arm 103. As discussed above, flexible arm 103 is repeatably moveable between flexed and unflexed positions, so that input device 107 is moveable in response to a force being applied to it. It should be noted that one or more of lights 114b can be directed at input device 107 so that light emitted by light 114 illuminates input device 107. It should also be noted that flexible arm 103 can be replaced with flexible arm 113 of FIG. 1b.

In this embodiment, cable 106 (FIG. 1a) extends through flexible arm 103 and light post 122. Further, a light cable (not shown) is connected to light 114 and extends through light post 122, wherein the light cable provides a power signal to light emitters 114b.

In this embodiment, light post 122 extends upwardly from a curb 115 and curb 115 extends along a driveway (not shown). The moveable vehicle barrier in communication with input device 107 allows and restricts the movement of a vehicle along the driveway. The operator of the vehicle positions the vehicle so that he or she can access input device 107 by providing an input to keypad 108. If the vehicle is moved too close to curb 115, the vehicle can hit it and damage curb 115 and the vehicle. For example, a tire of the vehicle can engage curb 115 and leave unsightly scuff marks on it. Further, when the tire contacts the curb, it can scratch and dent the tire rim.

FIGS. 3a and 3b are side and top views, respectively, of flexible arm 103 and curb 115. The side view of FIG. 3a is the view looking in a direction 119 of FIG. 2. In this embodiment, flexible arm 103 extends over curb 115 so that input device 107 is held over a driveway 116 by a distance D. In accordance with the invention, distance D is chosen so that input device 107 can be engaged by the vehicle without the vehicle engaging curb 115. In some embodiments, distance D is chosen so that input device 107 is not held over curb 115. Distance D can be determined in many different ways. In this embodiment, distance D is the distance that a vehicle on driveway 116 can be from curb 115 without engaging input device 107 when flexible arm 103 is unflexed.

In accordance with the invention, input device 107 is moveable, as indicated by a direction arrow 117 (FIG. 3a), in response to a force F₁ being applied to it. In this example, force F₁ is directed in a direction perpendicular to and away from driveway 116. In other examples, force F₁ can be applied perpendicular to and towards driveway 116. A distance D_flex1 is zero when flexible arm 103 is in the unflexed position. Distance D_flex1 is non-zero when flexible arm 103 is in the flexed position. Flexible arm 103 flexes, and input device 107 moves distance D_flex1, in response to force F₁ being applied to device 107. Flexible arm 103 does not flex, and distance D_flex1 is driven to zero, when force F₁ is not applied to device 107. In this way, input device 107 can be moved towards and away from driveway 116 in a repeatable manner by flexing and unflexing flexible arm 103.

In accordance with the invention, input device 107 is moveable, as indicated by a direction arrow 118 (FIG. 3b), in response to a force F₂ being applied to it. In this example, force F₂ is directed in a direction parallel to driveway 116. A distance D_flex2 is zero when flexible arm 103 is in the unflexed position. Distance D_flex2 is non-zero when flexible arm 103 is in the flexed position. Flexible arm 103 flexes, and input device 107 moves a distance D_flex2, in response to force F₂ being applied to device 107. Flexible arm 103 does not flex, and distance D_flex2 is driven to zero, when force F₂ is not applied to input device 107. In this way, input device 107 can be moved parallel to driveway 116 in a repeatable manner by flexing and unflexing flexible arm 103.

It should be noted that, in some situations, forces F₁ and F₂ can both be applied to input device 107, such as when it is engaged by the hood of a vehicle. In these situations, flexible arm 103 is flexed in response to forces F₁ and F₂, and input device 107 is moved in response, so that distances D_flex1 and D_flex2 are both non-zero.

FIGS. 4a and 4b are top views of fixture 100 positioned proximate to curb 115, wherein flexible arm 103 is in unflexed and flexed positions, respectively. In accordance with the invention, flexible arm 103 is repeatably moveable between flexed and unflexed positions in response to engaging and disengaging, respectively, a vehicle 123. It should be noted that, in FIGS. 4a and 4b, light fixture 100 can be replaced with fixture 120 of FIG. 2.

Input device 107 engages vehicle 123 when vehicle 123 moves proximate to fixture 100 and curb 115 at a distance less than distance D (FIGS. 3a and 3b). When vehicle 123 engages input device 107, it applies a force to it, as discussed in more detail with FIGS. 3a and 3b. In response to the applied force, input device 107 moves in the direction shown by direction arrow 117 and/or 118 and flexible arm 103 flexes, as shown in FIG. 4b. Flexible arm 103 flexes so that there is a reduced likelihood of input device 107 and vehicle 123 being damaged when they are engaged together.

Input device 107 disengages vehicle 123 when vehicle 123 moves away from fixture 100 by a distance greater than distance D. When vehicle 123 is disengaged from input device 107, it does not apply a force to it, and distances D_flex1 and D_flex2 are driven to zero (FIG. 4a).
