Abstract:
A high-pressure mine door assembly for use in mine shafts configured with opposing wings, which enable the door to open and close quickly. The assembly includes a major hub and a minor hub positioned at or above the cap of the door assembly and coupled together via a connecting bar. A drive mechanism is coupled to the cap and the connecting bar, which facilitates the opening and closing of the wings of the door. The door assembly is configured in a 12-6 pitch orientation, requiring only a ⅔ rotation of the wings of the door assembly to fully open the door. Such a configuration also negates the effect of air pressure on operation of the door, as regardless of the direction of the airflow, with the airflow assisting one wing in opening and the other in closing.
Abstract:
The invention relates to an arrangement for locking and ejecting a movable furniture part, comprising two unlockable ejection devices arranged on both sides of a furniture body or on the movable furniture part, and spring-loaded ejectors, wherein the unlockable ejection devices comprise a catch element mounted on a linearly displaceable carriage, the catch element engaging into a slotted guide path having the shape of a heart curve and by which the movable furniture part can be held in a closed latching position (E) via a locking element. According to the invention, this latching position (E) can be released by overpressing the movable furniture part towards the interior, wherein the linearly displaceable carriages of the two unlockable ejector devices are motionally coupled via a rotatable synchronization rod.
Abstract:
A safety cabinet includes an enclosure having a double-walled construction and a pair of doors to selectively seal the enclosure. The safety cabinet can be used to store, for example, flammable liquids, flammable waste, corrosives, pesticides, or combustible waste. The safety cabinet incorporates a sequential door-closing system that sequentially closes the doors of the safety cabinet in a predetermined order.
Abstract:
A hinge is provided that permits a user to use a computer system either as a laptop computer or a tablet computer. The hinge may comprise a hinge block and an inhibitor stopper. The hinge block may have a first hinge member and a second hinge member. The inhibitor stopper may be disposed between the first hinge member and the second hinge member. The inhibitor stopper may have a first wing and a second wing. The inhibitor stopper may be attached to the hinge block. The first and second wings may be rotatable around an axis.
Abstract:
Simultaneous displacement device for sliding doors, being a first sliding leaf (7) joined to a first cogged belt (9) established between a first set of cogged pulleys (11) and (12) which rotate freely on a first axis (13) and second axis (14) respectively, and a second sliding leaf (8) joined to a second cogged belt (10) established between a second set of cogged pulleys (15) and (16) which rotate freely on said first axis (13) and second axis (14) respectively, said device comprising clutching means (2) which enable to adopt a first position where the first cogged belt (9) and the second cogged belt (10) move independently, and a second position where the first cogged belt (9) and the second cogged belt (10) move integrally to enable the simultaneous displacement of the first sliding leaf (7) and of the second sliding leaf (8).
Abstract:
A gate operator for opening and closing an exterior gate includes an elongate hollow housing for rigid vertical mounting relative to the ground. First and second spaced-apart hinge assemblies for securing to the gate are mounted within the housing for pivoting relative to the housing. A motor is mounted within the housing and is coupled to at least one of the first and second hinge assemblies for causing the at least one of the first and second hinge assemblies to pivot between first and second positions and thus cause the gate to pivot between opened and closed positions. A method for manufacturing the gate operator and a folded gate assembly utilizing the gate operator are provided.
Abstract:
Provided is a door opening/closing device with a support member capable of positioning the door opening/closing device at a proper position of a housing and facilitating the mounting work of the door opening/closing device to the housing. The door opening/closing device with a support member has the support member 8 which is mountable on a housing 1; and a door opening/closing device which is mounted on the support member 8 and configured to move a door 2 relative to the housing 1. The support member 8 has a first positioning part 10a for positioning at a front surface of one of an upper plate 1a and a side wall 1b of the housing 1, and a second positioning part 10b which is able to be placed against the other of the upper plate 1a and the side wall 1b of the housing 1.

Abstract:
A hinge device increases an open angle of a second member relative to a first member without enlarging the hinge device. A first pulley is fixed to a first mounting member mounted on the first member. A second pulley is fixed to a second mounting member mounted on the second member. A timing belt runs between the first and second pulleys. One end of a connecting member that connects the first mounting member to the second connecting member connects rotatably to an axis part of the first mounting member, with the opposite end connected rotatably to an axis part of the second mounting member. Pins to that abut to the outside of the timing belt are provided such that the width between one side and the opposite side of the timing belt becomes smaller than the diameter of at least one of the first pulley and the second pulley.
Abstract:
An articulated device comprises a first member (4) that is provided with a first set of teeth fixedly connected thereto (20, 22). A second adjacent member (6) is provided with a second set of teeth fixedly connected thereto (24, 26). A coupling section (32, 38) is also provided on which the first set of teeth is hingeably supported around a first hinge axis (28, 34) and on which the second set of teeth is hingeably supported around a second hinge axis (30, 36) wherein the first set of teeth engages with the second set of teeth. A positioning device sets an angular position of the first and second members relative to the coupling section.
