20090061703 | Manually Operated Propelling Device - A propelling device includes a driving unit disposed in a housing. The driving unit includes first and second bevel gears connected coaxially and respectively to upper and lower ends of a vertical driving shaft, a third bevel gear disposed on and co-rotatable with a transverse driving shaft and meshing with the first bevel gear, and a fourth bevel gear connected fixedly and coaxially to a front end of a longitudinal driving shaft and meshing with the second bevel gear. An impeller is disposed on a rear end of the longitudinal driving shaft extending outside the housing, and is co-rotatable with the longitudinal driving shaft. Two operating crank members are connected fixedly and respectively to opposite ends of the transverse driving shaft, and are co-rotatable with the transverse driving shaft. | 03-05-2009 |
20090137164 | MANUALLY OPERATED BOAT - A manually operated boat includes a propelling device including an upright driving rod extending through and rotatable relative to a floating member and having opposite upper and lower end portions that extend outwardly of the floating member, an operating member connected fixedly to the upper end portion of the driving rod, and a paddle member connected fixedly to the lower end portion of the driving rod so as to allow co-rotation of the operating member with the paddle member. The paddle member has a resilient paddle body having first and second paddle surfaces opposite to each other in a direction perpendicular to the driving rod. | 05-28-2009 |
20090165211 | Inflatable Bed - An inflatable bed includes a top sheet, a bottom sheet, an endless surrounding belt, and a plurality of pull belts. The surrounding belt cooperates with the top and bottom sheets to define an inflatable space. The surrounding belt has a bow tie shaped cross-section and includes vertically opposite upper and lower hollow portions. The upper hollow portion has a first surrounding surface confronting the inflatable space and connected to a periphery of the top sheet. The lower hollow portion has a second surrounding surface confronting the inflatable space and connected to a periphery of the bottom sheet. The pull belts are disposed in the inflatable space. Each of the pull belts has opposite top and bottom edges connected respectively to the top and bottom sheets. | 07-02-2009 |
20090183781 | OPEN STATE MAINTAINABLE VALVE DEVICE FOR AN INFLATABLE ARTICLE - A valve device includes a tubular member fitted into an inflatable article, a flexible diaphragm having a peripheral region which engages a valve seat of the tubular member through a mounting support and an intermediate surrounding region which has a portion that can be flexed to deflect a corresponding portion of the peripheral region from the valve seat, and a positioning member which is actuated to be displaced between normally-closed and deflating positions so as to bring an engaging end thereof to be proximate to or distal from the valve seat. In the deflating position, the flexed portion is vested with an increment of biasing force that is counteracted by a resisting force at an actuated end so as to keep the peripheral portion in a deflected position for maintaining the valve device in an open state. | 07-23-2009 |
20110180169 | Air pump capable of inflating and deflating an inflatable product - An air pump includes a sliding member disposed movably a housing and cooperating with the housing and a partition casing in the housing to define first and second chambers thereamong. The air pump is operable between a deflation state, where air from an inflatable product connected to an air nozzle on the housing into an air impeller chamber in the partition casing through the first chamber and an air inlet in the partition casing is driven by rotation of an air impeller to flow outside the air pump through an air outlet in the partition casing, the second chamber and an first vent unit in housing, and an inflation state, where air flowing from the outside into the air impeller chamber through a second vent unit in the sliding member, an air pipe of the sliding member and the air inlet is driven to flow into the inflatable product through the air outlet, the first chamber and the air nozzle. | 07-28-2011 |
20120031265 | INFLATABLE PAD HAVING REINFORCING BELTS - An inflatable pad includes: an inflatable pad body having a looped surrounding layer interconnecting top and bottom layers to cooperatively define an inflatable space; and a reinforcing belt unit disposed in the inflatable space in the inflatable pad body and connected between the top and bottom layers of the inflatable pad body. The reinforcing belt unit includes two coupling belts and a main reinforcing belt. Each coupling belt is attached fixedly and partially to a corresponding one of the top and bottom layers of the inflatable pad body, and has a central portion that is spaced apart from the corresponding one of the top and bottom layers of the inflatable pad body and that is connected to a corresponding one of opposite looped end portions of the main reinforcing belt. | 02-09-2012 |
20120285552 | AIR VALVE DEVICE FOR AN INFLATABLE ARTICLE - An air valve device is adapted to be fitted into an opening of an inflatable article, and includes a valve seat having a seat body that is disposed between an inflating port and a conduit, and a valve disc unit disposed in the conduit to be moved between opened and closed positions, and having a valve disc connected with a plunger, an elastomeric seal ring superimposed on a padded region of the valve disc. A rigid retaining cap is disposed to bring abase layer of the seal ring in an abutting engagement with the padded region of the valve disc so as to secure the seal ring to the valve disc while permitting a sealing marginal layer of the seal ring to be air-tightly engaged with the seat body in the closed position. | 11-15-2012 |
20130012082 | PULL BELT FOR AN INFLATABLE DEVICE - A pull belt is adapted for use in an inflatable device, and includes a main belt body having opposite first and second lengthwise end portions and formed with at least one first pleat at the first lengthwise end portion to bend the main belt body at the at least one first pleat toward the first lengthwise end portion. | 01-10-2013 |
