Sliding transponder shield box
A shield box is provided for a toll transponder. The shield box may selectively shield thee toll transponder. The shield box may include a case that is securable to a vehicle windshield. At least a portion of the case may include a shielding material. The shield box may further include a tray configured to slide into and out of the case. The tray may support the toll transponder outside of the case and push the transponder toward a vehicle windshield to cause the toll transponder to make contact or be proximate with the vehicle windshield.
1 . An apparatus for retaining and selectively shielding a transponder, the apparatus comprising:
a case securable to a vehicle windshield, at least a portion of the case comprising a shielding material; and
a tray slidably coupled to the case and configured to couple to a transponder, wherein
the tray is configured to slide between a first position and a second position relative to the case,
the tray is configured to enclose the transponder within the case when the tray is in the first position, and
the tray is extended out of the case in a first direction, and is configured to extend the transponder in a second direction perpendicular to the first direction when the tray is in the second position, the second direction being toward the vehicle windshield.
2 . The apparatus of claim 1 , wherein the tray comprises:
a receptacle configured to slidably engage with the case;
a platform configured to couple to the transponder, the platform configured to engage with the receptacle; and
one or more biasing elements between the receptacle and the platform that provide a force to bias the platform away from the receptacle.
3 . The apparatus of claim 2 , wherein the platform and the receptacle engage via a snap joint, the snap joint comprising a hook on the platform and a slot on the receptacle, the slot sized and shaped to allow the hook to slide up to an end of the slot.
4 . The apparatus of claim 2 , wherein the platform comprises a ramp that engages with an edge of the case to provide a compression force when the tray is moved from the second position to the first position.
5 . The apparatus of claim 4 , wherein the ramp comprises a set of ridges that provide contact surfaces with the edge of the case.
6 . The apparatus of claim 2 , wherein the platform includes a recess sized and shaped to receive the transponder.
7 . The apparatus of claim 1 , wherein when in the second position, the tray supports the transponder outside of the case and pushes the transponder toward the vehicle windshield to cause the transponder to make contact with the vehicle windshield.
8 . The apparatus of claim 1 , wherein the case further comprises two interior protrusions, and
the tray comprises a detent that selectively engages with the two interior protrusions to provide a first click point when the tray slides into the first position and a second click point when the tray slides into the second position.
9 . An apparatus for retaining and selectively shielding a transponder, the apparatus comprising:
a case securable to a vehicle windshield, at least a portion of the case comprising a shielding material; and
a tray comprising:
a receptacle configured to slidably engage with the case;
a platform configured to couple to the transponder and to engage with the receptacle; and
one or more biasing elements between the receptacle and the platform that provide a force to bias the platform away from the receptacle.
10 . The apparatus of claim 9 , wherein the tray is configured to slide between a first position and a second position relative to the case,
when in the first position, the platform is within the case, and
when in the second position, the tray is extended out of the case in a first direction, and the platform is biased to extend in a second direction perpendicular to the first direction.
11 . The apparatus of claim 10 , wherein when in the second position, the tray supports the transponder outside of the case and pushes the transponder toward the vehicle windshield to cause the transponder to make contact with the vehicle windshield.
12 . The apparatus of claim 10 , wherein the platform comprises a ramp that engages with an edge of the case to provide a compression force when the tray is moved from the second position to the first position.
13 . The apparatus of claim 12 , wherein the ramp comprises a set of ridges that provide contact surfaces with the edge of the case.
14 . The apparatus of claim 10 , wherein the case further comprises two interior protrusions, and
the tray comprises a detent that selectively engages with the two interior protrusions to provide a first click point when the tray slides into the first position and a second click point when the tray slides into the second position.
15 . The apparatus of claim 9 , wherein the platform and the receptacle engage via a snap joint, the snap joint comprising a hook on the platform and a slot on the receptacle, the slot sized and shaped to allow the hook to slide up to an end of the slot.
16 . The apparatus of claim 9 , wherein the platform includes a recess sized and shaped to receive the transponder.
17 . A shield box apparatus comprising:
a housing securable to a vehicle windshield, the housing comprising a front panel and a back panel coupled together to form an enclosure with an opening along one side; and
a tray configured to slide in and out of the opening of the housing and couple to a transponder,
wherein the tray is configured to extend toward the vehicle windshield when the tray is slid out of the opening of the housing and collapse when the tray is slid into the opening, wherein the tray comprises:
a receptacle configured to slidably engage with the housing;
a platform configured to couple to the transponder and to engage with the receptacle; and
one or more biasing elements between the receptacle and the platform, wherein the one or more biasing elements expand the tray by extending the platform away from the receptacle and toward the vehicle windshield when secured to the vehicle windshield.
18 . A shield box apparatus comprising:
a housing securable to a vehicle windshield, the housing comprising a front panel and a back panel coupled together to form an enclosure with an opening along one side; and
a tray configured to slide in and out of the opening of the housing and couple to a transponder,
wherein the tray is configured to extend toward the vehicle windshield when the tray is slid out of the opening of the housing and collapse when the tray is slid into the opening, wherein the tray comprises:
a receptacle configured to slidably engage with the housing;
a platform configured to couple to the transponder, the platform configured to engage with the receptacle; and
one or more springs between the receptacle and the platform that provide a force to bias the platform away from the receptacle.
19 . The shield box apparatus of claim 18 , wherein the platform comprises a ramp that engages with an edge of the opening of the housing to provide a compression force when the tray is slid into the opening of the housing.
