20090308561 | METHOD FOR MANUFACTURING HOSE COUPLINGS - A method for manufacturing hose couplings is composed of three steps as follows. The first step involves jointing and fixing a top casting-cavity insert and a bottom casting-cavity insert within a mold base of a casting machine. The second step is injecting a high-temperature molten metal into both the casting-cavity inserts, so that the molten metal can fill up the casting-cavity inserts. The third step is cooling the casting-cavity inserts by using a cooling liquid, so that the cooled and solidified metal can be released from the casting-cavity inserts to form a hose coupling. By using the method, various types of top casting-cavity inserts and bottom casting-cavity inserts may be adapted as desired and, therefore, various types of hose couplings may be manufactured as desired. | 12-17-2009 |
20100132096 | STRUCTURE FOR SAFETY HELMET - A structure for a safety helmet comprising an extendable/retractable visor. The visor is connected on each side by a connective part to a slotted moveable seat having a saw-tooth shaped position-limiting slot engaging a protrusion to control the position of the visor. The moveable seat is connected to a connective portion having a shaft with one or more protrusions engaging a connective hole with one or more indentations on the moveable seat. A seating unit having one or more engagement elements for affixation to the helmet is connected via a slot to a protrusion on the inside of a push seat. The protrusion has a threaded hole which engages the connective hole of the connective portion and is fastened thereto, e.g. by a screw. Upon assembly and fixation to the helmet, the visor may be extended or retracted by pushing on the push seat. | 06-03-2010 |
20100132097 | STRUCTURE FOR SAFETY HELMET - The safety helmet structure comprises a main body, an outer visor, an inner visor assembly including an inner visor and two moveable seats, a connective portion, a seating unit and a push seat. A connective part is disposed on both sides of the inner visor. The two moveable seats are connected with the connective parts through slots. A position-limiting slot is provided on the outer side of the moveable seat. A hole is provided on the rear part of the moveable seat. The moveable seat may be connected with the helmet through the hole. The moveable seat is connected with the connective portion through the connective hole. The inner visor may be retracted into the helmet or extended out by merely pushing the push seat. | 06-03-2010 |
20120043753 | TUBULAR CONNECTION STRUCTURE - A tubular connection structure comprises: a tubular connection body, having a tubular room, each of the two sides of which has an open slot, the two sides of the open slot being respectively extended to form two pivotal bases, the bottom of the tubular connection body being extended to form a fastening base; a clasp lever, being pivotally connected to the two pivotal bases of the tubular connection body, the one end being a pressing portion, the other end being a stirring portion that has a stirring lever accommodating base; a stirring lever, being accommodated in the stirring lever accommodating base, the top of the stirring lever being a stop convex portion that is to fasten the fastening base; a reset component, the one end of the reset component being urged to the stirring lever, the other end being urged to the clasp lever, so that a flexible resistant force is between the stirring lever and the clasp lever; and a fixing member, which makes the pivotal connection of the clasp lever and the two pivotal bases and the pivotal connection of the stirring lever and the stirring lever accommodating base. | 02-23-2012 |

20120260407 | NOSE-SHIELDING DEVICE FOR HELMET - A nose-shielding device comprises: a nose-shielding body, which has a nose-shielding surface and a positioning surface that are about perpendicular to each other, a nose-shielding portion being located around the central of the nose-shielding surface and protruded upward, a nose-shielding room being formed accordingly inside the nose-shielding portion, a nose-touching portion being formed at the bottom surface of the nose-shielding portion, an adjusting room being formed between the nose-touching portion and the bottom surface of the nose-shielding portion. | 10-18-2012 |
20130174313 | NOSE-SHIELDING DEVICE FOR HELMET - An improved nose-shielding device comprises: a nose-shielding body, which has a nose-shielding surface and a positioning surface that are about perpendicular to each other, a nose-shielding portion is located around the central of the nose-shielding surface and protruded upward, a nose-shielding room is formed accordingly inside the nose-shielding portion, a nose-touching portion is formed at the bottom surface of the nose-shielding portion, an adjusting room is formed between the nose-touching portion and the bottom surface of the nose-shielding portion, and the improved nose-shielding device is characterized in that: the nose-shielding portion has a flexible folded member that integrates with a portion, corresponding to the bridge of an operator nose, of the nose-shielding portion, and is adjustable for the folding degree of the folded member according to the figure of the bridge of the operator nose, thus the nose-shielding body more fits the operator nose. | 07-11-2013 |
20130229812 | ELECTRICAL ENERGY SUPPLY INDICATOR FOR A HELMET - An electrical energy supply indicator for a helmet is disclosed to employ a casing having a storage chamber for housing an electrical resistor, a light-emitting diode (LED), a cover plate, a female terminal socket; wherewith the storage chamber has a compartment plate, the female terminal socket has an article locking member, a pin receiving member having four trapezoidal faces, an anode and a cathode for connecting with the resistor and LED. The locking member is immobilized between the compartment plate and an interior surface, the receiving member passes through the receiving channel to connect externally with a male terminal pin. The LED operates to determine if attached electrical circuit is powered. A slant-faced extrusion block is on the underside of the cover plate to superimpose onto the locking member such that the locking member can be more secured inside the casing, thereby preventing undesirable movement of the female terminal socket. | 09-05-2013 |
20130338558 | ANKLE PROTECTING DEVICE - An ankle protecting device comprises: a wrapping sheath having a lower-leg sheath, a foot sheath and a loincloth that are integrated with thereof, the loincloth constricts the wrapping sheath on a sole, an ankle and a lower leg and is adjustable for tightness thereof; an internal supporting plate and an outer supporting plate fastened on the left and right sides of the wrapping sheath respectively, the shapes of the internal supporting plate and the outer supporting plate are symmetrical to each other, the internal supporting plate and the outer supporting plate | 12-19-2013 |
