[0028] The present invention relates to a device for air and surface disinfection. Hereinafter, this specification will describe the present invention according to the preferred embodiments. It is to be understood that limiting the description to the preferred embodiments of the invention is merely to facilitate discussion of the present invention and it is envisioned without departing from the scope of the appended claims.

[0029] Figure 1 illustrates a preferred embodiment of the present invention. Referring to Figure 1 to Figure 7 an entrance wing gate system comprises of a linear actuator (150), a fixed frame (110), an end frame (130), a plurality of intermediate frames (120a-n), an anchor bracket (160), and a plurality of panels (140).

[0030] The linear actuator (150) operates the wing gate. The fixed frame (110) is configured to anchor the linear actuator (150) by a first actuator pivot bracket (152a) attached to the fixed frame (110) at a first distal end of the linear actuator (150). The end frame (130) is configured to receiving the linear actuator (150) by a second actuator pivot bracket (152b) attached to the end frame (130) at a second distal end of the linear actuator (150). The plurality of intermediate frames (120a-n) are pivoted at a distal end connected to an anchor bracket (160). The plurality of panels (140), wherein each panel (140) is attached to each intermediate frame (120a-n) and the end frame (130). The anchor bracket (160) is configured to anchor the intermediate frame (120a-n) and the end frame (130) and to enable the intermediate frame (120a-n) and the end frame (130) to pivot at anchor points (162, 162a-n) on the anchor bracket (160). The intermediate frame (120a-n) includes one or more tension spring (200) configured to float the intermediate frame (120a-n) in position.

[0031] The fixed frame (110) is a free-standing structure that is anchored to the ground. Apart from the ground, the fixed frame (110) does not need to be secured to other objects and / or supports. This does not restrict the option to secure the fixed frame (110) to other objects and / or supports. For example, the fixed frame (110) can be secured to the anchor bracket (160) for additional support. The fixed frame (110) can be attached to the ground, objects and supports by bolts, welding, straps, but not limited to such.

[0032] Referring to Figure 8, the intermediate frame (120a-n) and end frame (130) pivot about a pivot pin (400) located at each anchor points (162, 162a-n).

[0033] Referring to Figure 5, the first intermediate frame (120a) preferably includes two or more tension springs (200) configured to float the first intermediate frame (120a) at a first angle (1210a) from the end frame (130).

[0034] The second intermediate frame (120b) includes two or more tension springs (200) configured to float the second intermediate frame (120b) at a second angle (1210b) from the end frame (130), wherein the second angle (1210b) is greater than the first angle (1210a).

[0035] The two or more tension springs (200) of the first intermediate frame (120a) and second intermediate frame (120b) can be substituted with a single tension spring (200) having a tension equivalent to the respective total tension of the two or more tension springs (200).

[0036] Referring to Figure 6, The third intermediate frame (120c) includes one or more tension spring (200) configured to float the third intermediate frame (120c) at a third angle (1210c) from the end frame (130), wherein the third angle (1210c) is greater than the second angle (1210b).

[0037] The tension spring (200) in the intermediate frame (120a-n) in proximity to the end frame (130) is configured to float the intermediate frame (120a-n) at an angle (1210a-n) from the end frame (130).

[0038] The tension spring (200) in an adjacent intermediate frame (120b-n) in proximity to the fixed frame (110) is configured to float at another angle (1210b-n) from the end frame (130), wherein the another angle (1210b-n) is greater than the angle (1210a-n) of the intermediate frame (120a-n) in proximity to the end frame (130).

[0039] The tension spring (200) in the intermediate frame (120a-n) in proximity to the end frame (130) is configured to have a total tension greater than the total tension of the tension spring (200) in the intermediate frame (120b-n) in proximity to the fixed frame (110). The total tension in the tension spring (200) of the first intermediate frame (120a) and second intermediate frame (120b) provides 90kg to 130kg of tension for pulling up the first intermediate frame (120a) and second intermediate frame (120b).

[0040] The total tension in the tension spring (200) of the third intermediate frame (120c), fourth intermediate frame (120d) to the n th< intermediate frame (120n) provides 40kg to 70kg of tension for pulling down the third intermediate frame (120c), fourth intermediate frame (120d) to the n th< intermediate frame (120n).

[0041] The present invention differs from conventional solutions in that the panels (140) are supported by floating intermediate frames (120a-n). The intermediate frames (120a-n) are not operated by a motor. The intermediate frames (120a-n) are floated in position by tension force of the respective tension spring (200).

[0042] The tension springs (200) reduce the load on the linear actuator (150) as the floating of the intermediate frames (120a-n) is supported by the tension springs (200).

[0043] Conventionally, each frame and / or panel of a fan styled gate is operated by a direct or indirect connection to a motor. By contrast, the present invention uses the linear actuator (150) to operate only the end frame (130).

[0044] Referring to Figure 9, the intermediate frame (120a-n) is a hollow frame having a protrusion (1220) at a side (1201) of the intermediate frame (120a-n) comprising a groove joint (1222) to receive a tongue joint (310) of an interlock tip (300), and a slot (1224) for receiving a panel (140) on the intermediate frame (120a-n). The side (1201) of the intermediate frame (120a-n) further includes an extension (1230) to support the panel (140).

[0045] Referring to Figure 10, the interlocking means include a tongue and groove configuration. The open distal end of the panel (140) has an interlock tip (300) comprising a tongue joint (310) and a bearing (330). The bearing (330) is configured to enable the interlock tip (300) to glide smoothly over the surface of an adjacent panel (140). In addition, the bearing (330) functions as a spacer to align the tongue joint (310) of the interlock tip (300) with the corresponding groove joint (1222) of the adjacent intermediate frame (120a-n) enabling a secure connection.

[0046] The interlocking means provides a safety feature. The interlock means positions a panel (140) relative to the adjacent panel (140) in proximity to the fixed frame (110).

[0047] The interlocking means prevents panels (140) from falling in an uncontrolled manner during operation by having a falling panel (140) latching on to the adjacent panel (140) in proximity to the fixed frame (110). The latched adjacent panel (140) lifts the falling panel (140) using the combined tension of the tension springs (200) of one or more interlocked intermediate frame (120a-n). Wherein, the one or more interlocked intermediate frame (120a-n) is positioned between the fixed frame (110) and the falling panel (140).

[0048] The bearing (330) is located at an end of the interlock tip (300), wherein the interlock tip (300) is located at a top distal end of each panel (140) attached to an intermediate frame (120a-n) or the end frame (130).

[0049] The bearing (330) is preferably made of a low friction material such as high density polyethylene (HDPE), polyoxymethylene, nylon, but not limited to such.

[0050] Referring to Figure 11, the linear actuator (150) is extended to close the wing gate (100). The panels (140) of the wing gate (100) interlocks with the adjacent intermediate frame (120a-n) when the wing gate (100) is in the close position.

[0051] Referring to Figure 12, The linear actuator (150) is retracted to open the wing gate (100). The plurality of intermediate frames (120a-n) and panels (140) are folded in a vertical orientation when the wing gate (100) is in the open position.

[0052] The present invention consists of features and a combination of parts hereinafter fully described and illustrated in the accompanying drawings, it being understood that various changes in the details may be made without departing from the scope of the invention or sacrificing any of the advantages of the present invention.

[0053] Throughout this specification, unless the context requires otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated step or element or integer or group of steps or elements or integers, but not the exclusion of any other step or element or integer or group of steps, elements or integers. Thus, in the context of this specification, the term "comprising" is used in an inclusive sense and thus should be understood as meaning "including principally, but not necessarily solely".

[0034] The second intermediate frame (120b) includes two or more tension springs (200) configured to float the second intermediate frame (120b) at a second angle (1210b) from the end frame (130), wherein the second angle (1210b) is greater than the first angle (1210a).

[0035] The two or more tension springs (200) of the first intermediate frame (120a) and second intermediate frame (120b) can be substituted with a single tension spring (200) having a tension equivalent to the respective total tension of the two or more tension springs (200).

[0036] Referring to Figure 6, The third intermediate frame (120c) includes one or more tension spring (200) configured to float the third intermediate frame (120c) at a third angle (1210c) from the end frame (130), wherein the third angle (1210c) is greater than the second angle (1210b).

[0037] The tension spring (200) in the intermediate frame (120a-n) in proximity to the end frame (130) is configured to float the intermediate frame (120a-n) at an angle (1210a-n) from the end frame (130).

[0038] The tension spring (200) in an adjacent intermediate frame (120b-n) in proximity to the fixed frame (110) is configured to float at another angle (1210b-n) from the end frame (130), wherein the another angle (1210b-n) is greater than the angle (1210a-n) of the intermediate frame (120a-n) in proximity to the end frame (130).

[0039] The tension spring (200) in the intermediate frame (120a-n) in proximity to the end frame (130) is configured to have a total tension greater than the total tension of the tension spring (200) in the intermediate frame (120b-n) in proximity to the fixed frame (110). The total tension in the tension spring (200) of the first intermediate frame (120a) and second intermediate frame (120b) provides 90kg to 130kg of tension for pulling up the first intermediate frame (120a) and second intermediate frame (120b).

[0040] The total tension in the tension spring (200) of the third intermediate frame (120c), fourth intermediate frame (120d) to the n th< intermediate frame (120n) provides 40kg to 70kg of tension for pulling down the third intermediate frame (120c), fourth intermediate frame (120d) to the n th< intermediate frame (120n).

[0041] The present invention differs from conventional solutions in that the panels (140) are supported by floating intermediate frames (120a-n). The intermediate frames (120a-n) are not operated by a motor. The intermediate frames (120a-n) are floated in position by tension force of the respective tension spring (200).

[0042] The tension springs (200) reduce the load on the linear actuator (150) as the floating of the intermediate frames (120a-n) is supported by the tension springs (200).

[0043] Conventionally, each frame and / or panel of a fan styled gate is operated by a direct or indirect connection to a motor. By contrast, the present invention uses the linear actuator (150) to operate only the end frame (130).

[0044] Referring to Figure 9, the intermediate frame (120a-n) is a hollow frame having a protrusion (1220) at a side (1201) of the intermediate frame (120a-n) comprising a groove joint (1222) to receive a tongue joint (310) of an interlock tip (300), and a slot (1224) for receiving a panel (140) on the intermediate frame (120a-n). The side (1201) of the intermediate frame (120a-n) further includes an extension (1230) to support the panel (140).

[0045] Referring to Figure 10, the interlocking means include a tongue and groove configuration. The open distal end of the panel (140) has an interlock tip (300) comprising a tongue joint (310) and a bearing (330). The bearing (330) is configured to enable the interlock tip (300) to glide smoothly over the surface of an adjacent panel (140). In addition, the bearing (330) functions as a spacer to align the tongue joint (310) of the interlock tip (300) with the corresponding groove joint (1222) of the adjacent intermediate frame (120a-n) enabling a secure connection.

[0046] The interlocking means provides a safety feature. The interlock means positions a panel (140) relative to the adjacent panel (140) in proximity to the fixed frame (110).

[0047] The interlocking means prevents panels (140) from falling in an uncontrolled manner during operation by having a falling panel (140) latching on to the adjacent panel (140) in proximity to the fixed frame (110). The latched adjacent panel (140) lifts the falling panel (140) using the combined tension of the tension springs (200) of one or more interlocked intermediate frame (120a-n). Wherein, the one or more interlocked intermediate frame (120a-n) is positioned between the fixed frame (110) and the falling panel (140).

[0048] The bearing (330) is located at an end of the interlock tip (300), wherein the interlock tip (300) is located at a top distal end of each panel (140) attached to an intermediate frame (120a-n) or the end frame (130).

[0049] The bearing (330) is preferably made of a low friction material such as high density polyethylene (HDPE), polyoxymethylene, nylon, but not limited to such.

[0050] Referring to Figure 11, the linear actuator (150) is extended to close the wing gate (100). The panels (140) of the wing gate (100) interlocks with the adjacent intermediate frame (120a-n) when the wing gate (100) is in the close position.

[0051] Referring to Figure 12, The linear actuator (150) is retracted to open the wing gate (100). The plurality of intermediate frames (120a-n) and panels (140) are folded in a vertical orientation when the wing gate (100) is in the open position.

[0052] The present invention consists of features and a combination of parts hereinafter fully described and illustrated in the accompanying drawings, it being understood that various changes in the details may be made without departing from the scope of the invention or sacrificing any of the advantages of the present invention.

[0053] Throughout this specification, unless the context requires otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated step or element or integer or group of steps or elements or integers, but not the exclusion of any other step or element or integer or group of steps, elements or integers. Thus, in the context of this specification, the term "comprising" is used in an inclusive sense and thus should be understood as meaning "including principally, but not necessarily solely".
