Each lateral plate has a semicircular frame. The hood has two arc plates, and two arc frames each communicating with the corresponding semicircular frame. The safety door has two oblong windows, two handles, a plurality of rollers disposed on two sides of the safety door, and a plurality of rolling bearings disposed on two sides of the safety door. The rollers and the rolling bearings move along the corresponding arc plate and the corresponding semicircular frame.
Abstract: A movable blind fastened to the interior of an automobile comprises a cradle in the bottom and a bracket in each end of the cradle, with each bracket having a recess. Two engagement members each have a projection fitted into the recess and a double trough. Two plate members each have two pairs of opposite protuberances, a stop between the pairs of protuberances, and a shaft, with the protuberances and the stop being fastened to the double trough. Two pivot members each have slots disposed around a central bore and an enclosed box portion having transverse grooves disposed circumferentially. Two abutment members each have a central hole with the shaft inserted to fit in the central bore of pivot member and with the ridges engaged with the transverse grooves of the box portion. A blind cloth is fastened between a cross bar on the top and the cradle. The cross bar has a central activation member.
Abstract: An umbrella frame has a hollow shaft, an upper runner disposed on the hollow shaft, a lower runner receiving the hollow shaft, a winding device inserted through the hollow shaft, a pulley disposed on the hollow shaft, and a thread connected to the pulley and the winding device. A plurality of ribs are connected to the upper runner. A plurality of stretchers are connected to the lower runner and the ribs. A handle engages with the winding device.
Abstract: A vibration sensor device includes a hollow casing having a plurality of protrusions extending from an inner periphery of the casing. A ball is received in the casing and located in contact with at least three of the protrusions. The ball freely rolls when the casing senses vibration and the ball contacts different protrusions when it rolls so as to activate a cooperated warning device.
Abstract: An adjustable retaining device for a bass drum has a positioning plate securely engaged with the base, a first clamping plate pivotally connected with the position plate and a second clamping plate selectively engaged with and movable relative to the first clamping plate. A torque device engaged with the second clamping plate and having at least two rods securely extending out. The at least two rods slidably extend through the second clamping plate to allow the second plate to move with respect to the first clamping plate so as that a position of the second clamping plate is changeable with respect to the first clamping plate.
Abstract: An internet watch in accordance with the present invention further comprises a beat hand 4 to indicate internet time and a beat dial 5 mounted on the circumferential outside of the watch having an hour hand 1, a minute hand 2, and a second hand 3, thereby the internet watch can indicate internet time in addition to Standard time on the basis of GMT. The beat dial 5 is marked with 1000 beats with a day being divided into 1000 equal parts in internet time. The best dial 5 is assembled to be rotatable so that the internet time can be adjusted when the user travels in a region where a different standard time is applied. The beat hand 4 which rotates once a day and the beat dial 5 on which 1000 beats are marked facilitate to get internet time easily without conversion to the standard time based on GMT, which is variable according to the longitude.
Abstract: A ratcheting tool includes a handle and a head with a compartment. A drive member includes a first end, a second end, and a gear wheel formed between the first end and the second end. The gear wheel is rotatably mounted in the compartment and includes a toothed outer periphery. A pawl is mounted in the compartment and includes a toothed side facing the gear wheel teeth. A reversing plate is mounted to the first end of the drive member and pivotable about the rotational axis of the gear wheel between a first position and a second position. The reversing plate comprises a retainer block operably connected to a recess in an upper end of the pawl for moving the pawl between a first ratcheting position and a second ratcheting position.
Abstract: A chair comprises an arm mechanism and a back mechanism each having an adjustment screw for releasably securing a sleeve and a shroud to a J-bar so that a height of either arm or back mechanism can be adjusted relative to the j-bar. Also, a protruded enlargement is formed at a top end of the upright backrest support.
Abstract: An apparatus mounted on a valve for indicating a pressure of tire comprising a pressure indicator formed of transparent plastic and including a base having a scale, base consisting of an inner hollow cylinder sleeved on valve and an outer hollow cylinder with tops of cylinders open, a spring put on inner hollow cylinder, a seal put on inner hollow cylinder being urged by spring for eliminating a potential air flow through an inner or outer periphery of seal, and a cap having a downward peg engaged with valve, cap being releasably secured to a top of base. In indicating pressure of tire, air is flowed from within tire to push down seal through valve and pressure indicator so that a top of seal is aligned with one of marks of scale. Further, pressure indicator is disengaged from valve prior to inflating tire.
