Patent number: 7484351Abstract: In a deformable structure, connecting parts each of which has a base part are arranged longitudinally so that adjacent connecting parts are connected to each other. Respective first axes of the adjacent connecting parts are inclined to each other in a state that a spacer on one of the two adjacent base parts comes into contact with the other base part. When an external force is exerted on the deformable structure, the spacers restrain the deformable structure from being further curved into a radius of curvature smaller than a predetermined allowable radius of curvature. Most of the external force exerted on the deformable structure is born by the base parts and the spacers so that only a low force acts on the connecting parts. Thus the connecting parts do not break easily so that the deformable structure has a high strength.Type: GrantFiled: April 21, 2006Date of Patent: February 3, 2009Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Takashi Harada, Yuji Maeguchi, Takahiro Inada

Patent number: 7388154Abstract: A mechanism for confining a flat flexible cable of an image scanner in position is provided. The flat flexible cable is electrically connected between a circuit board and a carriage and bends differentially with the movement of the carriage relative to the circuit board under a scanning platform. The mechanism includes a confining member disposed between a first portion of the flat flexible cable and the scanning platform for isolating the flat flexible cable from the scanning platform. The confining member changes states and bends differentially with the movement of the carriage relative to the circuit board under the scanning platform, and has a bending resistance greater than that of the flat flexible cable. Accordingly, the confining member is kept at least a certain clearance from the scanning platform while confining the first portion of the flat flexible cable thereunder.Type: GrantFiled: September 15, 2006Date of Patent: June 17, 2008Assignee: Transpacific Plasma, LLCInventors: Hsi-Yu Chen, Yi-Yung Tsai, Chien-Kuo Kuan

Publication number: 20080120958Abstract: Cable protection and guide devices are susceptible to the generation of wear powders from friction between the cable and front and rear end portions of the connecting plates. The generation of wear powders and damage or disconnection of the cable is prevented and abrasion loss and impact noise due to contact between the side plate units is suppressed. Connecting plates 120 are symmetric such that the inner surface thereof includes small curvature portions, large curvature portions, and a flat surface or approximately flat surface having a radius of curvature which is larger than the large curvature portions.Type: ApplicationFiled: September 15, 2007Publication date: May 29, 2008Inventors: AKIHIKO UTAKI, SHOICHIRO KOMIYA

Publication number: 20080053057Abstract: The present invention provides a cable or the like protection and guide device which accommodates a cable or the like while allowing for examination of the cable. Smooth linear and flexional movement is achieved while not compromising the form stability of the cable accommodation space. Partial or local wear is suppressed. The device is made of a synthetic resin and accommodates a cable in a rectangular cable accommodating space. The accommodating space is surrounded by the outer circumferential wall portion, which is openable, a pair of side wall portions, and an inner circumferential wall portion. Inserting protrusion mechanisms, engagement mechanisms, slits, opening windows and flexion restricting piece portions contribute to the stability and usefulness of the device.Type: ApplicationFiled: July 26, 2007Publication date: March 6, 2008Inventors: Masaaki IKEDA, Shoichiro Komiya, Takayuki Matsuda

Patent number: 7334388Abstract: A link plate is proposed for forming at least one member of an energy guide chain, which has overlap regions with stops that limit the angular position of the energy guide chain. Each of the overlap regions has a central region which is surrounded by at least two regions in which some stop faces are formed. It is proposed that a first region has stop faces where these stop faces, in the case of an energy guide chain composed from link plates, determine a curvature region in a transition region between a lower trunk and upper trunk of the energy guide chain. The second region has stop faces which determine a prestressing in the energy guide chain. In addition to the two regions, the link plate may have a third region, which has at least one stop with at least one stop face, where the stop has a spring-elastic characteristic. Through the spring-elastic characteristic, damping of the movement during a pivoting process of the link plates is achieved.Type: GrantFiled: August 6, 2004Date of Patent: February 26, 2008Assignee: Kabelschlepp GmbHInventors: Erwin Eckl, Heiner Samen, Herbert Wehler

Patent number: 7317160Abstract: A cable or the like protection and guide device is disclosed in which inadvertent disconnection in a coupling portion of a side plate due to the repetition of flexional movements is avoided. Stress concentration is reduced in a flexion portion during restriction of flexional movements whereby excellent endurance on repeated flexion fatigue can be exhibited and in which the number of parts and the assembly operation can be reduced. Plates disposed in a right and left pair are integrally formed by a front side plate portion 111, a rear side plate portion 112, and a flexible coupling portion 113 interposed between the front side plate portion 111 and the rear side plate portion 112. The coupling portion 113 includes a thin plate-shaped central flexion allowable region 113a and base end continuous regions 113b, 113b with gradually increased plate thickness from the central flexion allowable region 113a side toward the front side plate portion 111 and rear side portion 112, respectively.Type: GrantFiled: August 4, 2006Date of Patent: January 8, 2008Assignee: Tsubakimoto Chain Co.Inventor: Akihiko Utaki
