Indoor smoking hood

摘要

The present invention features an indoor smoking hood system disposed on a sash window frame. The hood comprises a first side tubular frame and a second tubular frame. The frames are joined together by adjustment locks for the attachment of variable window width. The frames are attached to the window frame via a plurality of window clamps. A hood frame is slidably and pivotably attached to the first side tubular frame and second tubular frame. A clear plastic hood provides enclosure of the hood for a smoking area. A fan plate is attached to the top of the tubular frame with a plurality of fan plate clips. An exhaust fan is installed on the fan plate to air in the hood to outdoor.

(a) sash window (200) having a first sash (210) and a second sash (220), wherein the sashes (210, 220) are able to slide down along a window frame (240) to create an opening (230); wherein the window frame (240) has a first side (242) and a second side (244); (b) a first tubular frame (110), wherein the first tubular frame (110) has a U-shape profile with a top end arm (112), a lower end arm (114) and a central arm (116), wherein the top end arm (112) and lower end arm (114) are perpendicular to the central arm (116); (c) a second tubular frame (120), wherein the second tubular frame (120) has a U-shape profile with a top end arm (122), a lower end arm (124) and a central arm (126), wherein the top end arm (122) and lower end arm (124) are perpendicular to the central arm (126); (d) a first adjustment lock (130) and a second adjustment lock (136), wherein the top end arm (112) of the first tubular frame (110) and the top end arm (122) of the second tubular frame (120) pass through an aperture (131) within the first adjustment lock (130) from opposite directions and are securely tightened by a first screw (132); wherein the lower end arm (114) of the first tubular frame (110) and the lower end arm (124) of the second tubular frame (120) pass through an aperture (137) within the second adjustment lock (136) from opposite directions and are securely tightened by a second screw (138); (e) a plurality of window clamps (140) to securely attach the tubular frames to the window frame, wherein each window clamp (140) has a U-shape profile having a first clamp arm (142), a second clamp arm (144) and a central clamp arm (146), wherein the first clamp arm (142) and second clamp arm (144) are perpendicular to the central clamp arm (146), wherein the second clamp arm (146) has an aperture (147) for a third screw (148) to screw through and securely tighten to the first side (242) or second side (244) of the window frame (240), wherein the central arm of the first tubular frame (110) or second tubular frame (120) is firmly attached within the window clamps (140) via a secure means (149); (f) a tubular hood frame (150) having a U-shape with a central hood arm (151), first side hood arm (152) and a second side hood arm (154), wherein the first side hood arm (152) and second side hood arm (154) are perpendicular to the central hood arm (151), wherein the first side hood arm (152) has a first distal end tip (156) perpendicular to the first side hood arm (152), wherein the second side hood arm (154) has a second distal end tip (158) perpendicular to the second side hood arm (154), wherein the tubular hood frame (150) is slidably and pivotably attached to the first tubular frame (110) and second tubular frame (120) via two pivot clips (190), wherein each pivot clip (190) comprises a first pivot arm (192), a second pivot arm (194) and a circular arm (196), wherein the central arm (116) of the first tubular frame (110) or the central arm (126) of the second tubular frame (120) are configured to slidably fit inside the circular arm (194), wherein the first pivot arm (192) and the second pivot arm (194) are aligned together and have a circular aperture (198), wherein the first distal end tip (156) or second distal end tip (156) is configured to pass through the circular aperture (198); wherein the tubular hood frame (150) is rotatable around the circular aperture (198); (g) a hood enclosure (160) expanding from the top end arm (112) of the first tubular frame (110) and the top end arm (122) of the second tubular frame (120) to the central hood arm (151) of the tubular hood frame (150), wherein the hood enclosure also extends from the section of central arm (116) of the first tubular frame (110) above the pivot clip (190) to the first side hood arm (152), wherein the hood enclosure also extends from the section of central arm (126) of the second tubular frame (120) above the pivot clip (190) to the second side hood arm (154); (h) a fan plate (170) having a rectangle profile with a top side (171), lower side (172), a first side (173) and a second side (174), wherein the first side (173) and second side (174) are attached to the first tubular frame (110) and second tubular frame (120) respectively by at least one fan plate clip (175), wherein each fan plate clip (175) comprises a first clip arm (176), a second clip arm (177) and an arc-shaped arm (178), wherein the central arm (116) of the first tubular frame (110) or the central arm (126) of the second tubular frame (120) are configured to snuggly fit inside arc-shaped arm (178), wherein the first side (173) or second side (174) of the fan plate is disposed between the first clip arm (176) and second clip arm (177), wherein the first side (173) or second side (174) of the fan plate the first clip arm (176) and second clip arm (177) are securely tightened together via a secure screw and nut set (179);
