Patent number: 8376258Abstract: A webbing take-up device enabling a reduction in size of an overload release mechanism and easy adjustment of an operation torque of the overload release mechanism is provided. In the overload release mechanism of this webbing take-up device, rotary force of a large diameter gear is transmitted to a small diameter gear via plural annular friction springs. The friction springs are disposed between an inner periphery face of a main body portion of the large diameter gear and a tubular portion of the small diameter gear, side by side along an axial direction of the two gears. Consequently, a radial direction enlargement of the large diameter gear and small diameter gear due to space for disposing the friction springs may be restrained. Moreover, the operation torque of the overload release mechanism may be adjusted stepwise by changing the number of the friction springs to be used, in accordance with requirements.Type: GrantFiled: October 14, 2010Date of Patent: February 19, 2013Assignee: Kabushiki Kaisha Tokai-Rika-Denki-SeisakushoInventors: Takayoshi Ando, Teruhiko Koide, Masafumi Tsujimoto

Patent number: 8292209Abstract: An operating load of an overload releasing mechanism is made to be high by a simple method. In a webbing retractor, spring claws engage with recesses of a rotor, and a gear wheel and the rotor are connected. When relative rotational force is applied between the rotor and the gear wheel, the spring claws elastically deform and engagement thereof with the recesses is released. Due thereto, connection of the rotor and the gear wheel is released, and the overload releasing mechanism is operated. Here, urging members urge the spring claws toward a side of engaging with the recesses. Due thereto, the operating load of the overload releasing mechanism can be made to be high by a simple method of merely adding the urging members.Type: GrantFiled: February 1, 2011Date of Patent: October 23, 2012Assignee: Kabushiki Kaisha Tokai-Rika-Denki-SeisakushoInventors: Takuhiro Saito, Yasunori Hattori

Patent number: 7980503Abstract: To obtain a webbing take-up device that can not only transmit to a take-up shaft only rotation from a motor by a clutch but is also simple and compact. A clutch of this webbing take-up device has a simply configuration where sliders 144 of a clutch body portion 114 are caused by frictional force to be retained in a case, whereby the sliders 144 and lock bars 154 are caused to relatively move and the lock bars 154 are caused by this relative movement to move to positions where they engage with or disengage from a ratchet 134. Consequently, the overall configuration of a clutch 100 can be made significantly compact (thinned) in comparison to a configuration that causes a pawl to move using an inertial disk that is large and has weight as in a conventional clutch. Thus, the overall configuration of a webbing take-up device 10 can be made compact.Type: GrantFiled: August 26, 2010Date of Patent: July 19, 2011Assignee: Kabushiki Kaisha Tokai-Rika-Denki-SeisakushoInventors: Takuhiro Saito, Katsuki Asagiri, Shinji Mori

Patent number: 7316368Abstract: The present invention relates to portable hose carts for handling and storage of flexible hoses, such as garden or air hoses. The cart is primarily constructed of plastic components having a centrally rotatable spool for winding of the flexible hose, an enclosure for supporting the spool, wheels at one end of the base of the enclosure, and a handle assembly for tilting the frame onto the wheels to facilitate moving the device. The handle assembly is telescoping mounted and includes a handle mounted near the top of the handle assembly. The spool is rotatable by either a direct current powered motor or a folding manual crank. Power from the electrical motor is transferred to the spool via an infinitely adjustable torque transfer assembly. When the cover is in the open position, the direct current motor is operationally locked out, and when the cover is rotated into the closed position, the direct current motor is operable.Type: GrantFiled: August 12, 2004Date of Patent: January 8, 2008Assignee: Suncast CorporationInventors: Brian Moon, Lyle A.
