Abstract:
A door opening and closing apparatus opens and closes a slide door by cooperating with a guide roller unit fixed to the slide door of a vehicle. The guide roller unit includes a guide member and a belt-side bracket connected to the guide member. The door opening and closing apparatus includes a support member made of resin, plural pulleys supported at the support member, and a transmission belt engaged at the plural pulleys. The support member is fixed to a body of the vehicle and includes a rail portion at which the guide member is mounted. The belt-side bracket is fixed to the transmission belt. An electric drive source moves the transmission belt for opening and closing the slide door in a state where the guide member is guided along the rail portion. The support member includes an engagement portion configured to hold the belt-side bracket.
Abstract:
A door closer or operator includes a pivoting pinion on the door closer housing for transmitting door motion, and a cam connected thereto. A connecting member extends along a spring and engages the peripheral edge of the cam. Rotation of the cam causes a change in length of the portion of the connecting member between the position tangent to the cam peripheral edge and the spring second end to expand or compress the spring, resulting in a force transmitted along a longitudinal axis of the connecting member as a result of spring deflection. The cam peripheral edge has a profile with a varying radial distance between the cam axis and the connecting member at the position tangent to the cam peripheral edge such that the radial distance is changed as the spring expands or compresses to maintain a desired constant torque about the axis of the cam and pinion.
Abstract:
Provided is a small plug door device capable of performing an opening/closing operation and a plugging operation with a door drive mechanism for causing a force in a vehicle front-rear direction to act on a door, and further applicable also to a one-panel sliding door. A slide base 12 is installed slidably in a vehicle width direction relative to a fixed base 11. A door drive mechanism 13 for moving one door 104 in a vehicle front-rear direction via a connecting portion 19 has a drive portion 13a including an electric motor 21, a drive wheel member 13b, a follower wheel member 13c, and an endless member 13d, and is installed on the slide base 12. A guide portion 15 guides a shaft portion 14 provided on the connecting portion 19 so as to move the shaft portion 14 in a vehicle width direction. In a double-speed rail 16 in which a pinion 16c is disposed between two racks (16a, 16b), one rack 16b is connected to the slide base 12, the other rack 16a is connected to the door 104 side, and the pinion 16c is connected to the connecting portion 19.
Abstract:
A method determines a position of at least one element that can be moved by a drive belt of a drive unit. A system is made of such components. A program carries out the method. In order to determine an absolute position of the movable element in a simple manner, the drive belt is expanded over a measurement interval and a force required to do so is determined via an efficiency of the drive unit. An effective length of the drive belt is determined from the measurement interval and the force and from a modulus of elasticity and a cross-section. The position is determined from the effective length.
Abstract:
A system of ejecting a sliding door of a closet, comprising a plurality of ejection assemblies and a connecting mechanism, which connects one assembly to the other. Each ejection assembly comprises a rail and a slidable member configured to slide along the rail, where the rail engages with a frame of the closet. The connecting mechanism allows synchronizing the ejection force applied upon the door at different locations of the door, by connecting the ejection assemblies through the connecting mechanism. This configuration allows ejecting and retrieving of the door outwardly and inwardly by sliding the slidable member of each assembly along the rail.
Abstract:
A hinge assembly (4) for the connection of two panels (10, 12) at their adjacent edge regions (8d) to allow said panels to rotate up to 360 degrees relative to one another, the hinge assembly comprising an elongate member (20) providing two opposing curved surfaces adjacent the edge of each panel, said member co-operating with at least one pair of intermeshed gears (24), the assembly including connector means (34) for attaching each panel to said member and a bubble seal (22) disposed between the edge of each panel and each curved surface of the member.
Abstract:
A step unit comprises: a step member which is provided on the vehicle body side so as to be adjacent to a slide door of the vehicle and has a flat plate section on which an occupant's foot is placed; and a drive device which is affixed to the step member and drives the slide door to open and close the slide door. The step member is molded using a resin material and has a accommodation portion which is provided with a bottom formed below the upper surface of the flat plate section. The drive device is affixed while at least a part thereof is accommodated within the accommodation portion.
Abstract:
A synchronized actuation system for sliding doors, of the type of those formed, in which the pulling grip (1) and the free grip (2) have flanges (12) and the belt (4) and free (2) and pulling (1) grips are joined by a connecting shoe (3). With this configuration it is possible to carry out assembly and maintenance operations vertically and therefore in situ.
Abstract:
A window regulator for a vehicle includes first, second, third, fourth belt guiding members, a loop belt member including a plurality of teeth at a first surface and installed on the belt guiding members with exhibiting an eight-shape, and a rotational member engaged with the belt member and driven by a motor. The belt member includes first and second moving portions, which are arranged in parallel with each other, and third and fourth moving portions, which are arranged to intersect each other. First and second supporting members are connected to the belt member at the first and second moving portions, respectively. First and second twisted portions are provided at the belt member at the third and fourth moving portions, respectively, by twisting the belt member for reversing first and second surfaces of the belt member. Accordingly, the teeth of the belt member contact all of the belt guiding members.
