A seat cover is attachable to a seat section of a vehicle seat including a frame and an original cover, in the state of covering the original cover. The original cover is attached in the state where a hook-like original cover engaging tool including a pair of portions facing each other is hooked on an engageable portion of the frame. The seat cover includes a cover main body for covering the seat section, and a cover attaching tool provided along an end of the cover main body. The cover attaching tool includes a pair of cover seat portions facing each other and is hook-like. The cover attaching tool is allowed to be hooked on the original cover engaging tool hooked on the engageable portion.

A bordering edge of cover members and a bordering edge of cover members of a sitting portion cover of a seat cover are folded back in a longitudinal direction along raised portions of a sitting portion, creased, and attached to the rest of the members while being smoothly curved in conformance to the raised portions, thus to form a three-dimensional curved shape conforming to a top surface of the sitting portion. A bordering edge of cover members and a bordering edge of cover members of a backrest cover are folded back in a longitudinal direction along raised portions of a backrest portion, creased, and attached to the rest of the members while being smoothly curved in conformance to the raised portions, thus to form a three-dimensional curved shape conforming to a front surface of the backrest.

An air controller for an air pump capable of simply regulating the air delivery rate of the air pump. In an air pump including an electromagnetic driving mechanism 11, 13, 14, a magnet 17 carried on the tip of an arm 16, and a diaphragm 18 connected to the intermediate portion of the arm, the magnet being reciprocated by an electromagnetic action exerted between the electromagnetic driving mechanism and the magnet, the intake and discharge action being effected by the expansion and contraction of the diaphragm, the improvement lies in that the electromagnetic driving mechanism is mounted on a housing in such a manner that it is capable of advancing and retreating with respect to the magnet, whereby the advancement and retreat of the electromagnetic driving mechanism will cause the distance between the core 13 and magnet 17 and hence the reciprocating rate of the magnet to change, thus accomplishing the change of the air delivery rate.

Air controller for air pump

An aquarium air pump includes an electromagnetic motor-operated pump unit positioned in the housing of the pump and including two vibrating arms energized by the motor and each carrying a pump diaphragm forming with a closure member of the pump unit casing a pump chamber. Each vibrating arm is positioned on the casing to be pivoted to an operative position to close the respective closure member and a non-operative position in which the arm can be removed from the casing and interchanged. The pump housing includes a bottom part and a top part connectable to each other and sealed in the connected position by a peripheral seal. Cushioning cups support the pump unit in the pump housing to absorb vibrations.

Aquarium air pump

A vent valve of an air pump typically utilized in an aquarium apparatus. The vent valve includes a wall member with a vent hole in the wall member. A valve body having a flap member closes onto the vent hole. The closure action of the flap member is regulated so that the flap is twisted under the force of air flowing through the vent hole in a direction toward the flap member and returns to a closed position against the wall member with a rolling sidewise fold-down motion when an air flow lessens. In this manner, there is a reduction in the flapping noise of the valve.

An aquarium heater including a housing and a tube depending therefrom. An electric heating element is disposed in the bottom portion of the tube and a thermostatic control chassis is disposed in the upper portion of the tube. The control chassis includes two opposing housing sections matingly engaged in a nesting relationship to form a cylindrical housing unit which snugly fits into the tube and supports a bimetallic thermostatic switch together with associated circuitry and lead wires such that the thermostatic circuit elements are maintained securely positioned within the tube. The housing includes a gasket situated between a lip of the tube and the bottom wall of the housing, and a locking ring which clamps the rim of the tube in place. The tube is thereby held securely to the housing independently of the control chassis. A vertically slidable actuator arm engages a circular cam surface in the housing, where the cam surface converts rotary motion of a knob into vertical motion to thereby move the actuating arm. The lower end of the actuating arm engages and positions an adjustable contact member of the thermostatic switch to thereby maintain the temperature level of the heater as close as possible to a desired value.

Aquarium heater

A holding clamp for suspending an aquarium heater from the top of an aquarium frame. The clamp includes a bracket having a universal throat which can accommodate different sized frames. The clamp comprises an L-shaped bracket with a retaining member slidably associated with each of the legs of the bracket. Each retaining member defines an adjustable throat size with the opposing leg of the bracket. A locking device is situated on the clamp for securing the clamp to the frame with the retaining members positioned to accommodate the particular frame size. A holder connected to the bracket supports the aquarium heater from the frame and permits the aquarium heater to be suspended into the water.

A valve element for a small sized air pump. The valve element has legs, each of which are tightly secured within holes of valve-beds of a valve casing. A longitudinal hole is formed within each of the legs. The hole of the leg is opened at one end and closed at the other such that the hole terminates at a level horizontal to the lower surface of the valve-beds when the valve element is assembled.

Valve element for an air pump

An improved valve mechanism for a small sized air pump, having valve elements each of which is secured in a housing of a valve casing. The valve element has a semi-circular portion and a tongue. The semi-circular portion is trapezoidal and snuggly and firmly positioned within the housing.

Valve mechanism for an air pump

A vent valve of an air pump for charging air into a fish bowl which comprises a separator wall having an insertion vent hole, a valve body made of a silicone rubber and consisting of a disc-shaped tongue section having a semi-circular portion of a small diameter for closing said insertion vent hole and an annular disc-shaped fixed section of a large diameter connected to the base portion of said tongue section.
