Publication number: 20260338359Abstract: To improve convenience. In a flashlight 10, a hanging hook 70 is connected to a flashlight body 20 so as to be rotatable (movable) between a storage position and a hooking position. In the hooking position, since side hook sections 72L and 72R protrude so as not to substantially overlap with the flashlight body 20 and a battery pack 80, the hanging hook 70 is able to be stably hooked on a single pipe P. On the other hand, in the storage position, since the side hook sections 72L and 72R are stored so as to substantially overlap with the flashlight body 20, the hanging hook 70 is able to be compactly stored. Also, a center hook section 74 is able to stabilize the relative position of the side hook sections 72L and 72R in the hooking position. Furthermore, since the center hook section 74 does not overlap with at least the battery pack 80 in the storage position, attachment and detachment of the battery pack 80 is enabled.Type: ApplicationFiled: September 20, 2023Publication date: October 29, 2026Applicant: Koki Holdings Co., Ltd.Inventors: Ryo HAYAKAWA, Shingo KOSUGI, Takeshi TANIGUCHI, Ri SEN

Publication number: 20260175347Abstract: The present invention provides a working machine with a good lighting device. In a grinder, the lighting device is provided on both left and right sides of rear end of a gear housing and above wheel guard. Specifically, a holder of the lighting device is visibly exposed from an outer periphery of the gear housing in front view. When an LED of the lighting device emits light by an operator's operation of an operating portion, emitted light illuminates a lower portion of a spindle (i.e., a grinding wheel). In other words, a housing does not block the light emitted toward the grinding wheel from the lighting device on both sides of the housing, and the light can illuminate the grinding wheel disposed around the lower portion of the spindle. Therefore, the lower portion of the spindle (i.e., the grinding wheel) can be well illuminated.Type: ApplicationFiled: May 26, 2023Publication date: June 25, 2026Applicant: Koki Holdings Co., Ltd.Inventors: Kentaro HATAKEYAMA, Shingo KOSUGI

Publication number: 20260131443Abstract: An electric working machine with the same or more prevention or suppression of the transmission of the vibration than that of a related art because of having the less components and the less man-hours for assemblies than those of the related art is achieved. A hammer drill includes a motor serving as a driving source and is equipped with a drill bit driven by a driving force that is output from the motor. The hammer drill includes a main-body housing and a handle housing forming at least a part of an outer shell, and the main-body housing and the handle housing are connected to each other through an elastic body to be relatively movable. The elastic body is formed on the main-body housing and the handle housing by a double-layer molding, and is a part of a continuous resin cover covering surfaces of the main-body housing and the handle housing.Type: ApplicationFiled: April 14, 2025Publication date: May 14, 2026Inventors: Satoshi ABE, Shingo KOSUGI

Patent number: 12405047Abstract: Provided is an electrical device. In a setting unit, a right-room temperature display unit displays a set temperature or the current temperature of a first housing room. A left-room temperature display unit displays a set temperature or the current temperature of a second housing room. A right-room temperature setting button is an operation unit for a user to switch the set temperature of the first housing room. A left-room temperature setting button is an operation unit for a user switch the set temperature of the second housing room. The set temperature difference between the first and second housing rooms is controlled to be within a prescribed value. When the set temperature of one of the first and second housing rooms is changed so that the set temperature exceeds a prescribed value, a microcomputer automatically changes the other set temperature so that the set temperature difference is within a prescribed value.Type: GrantFiled: January 28, 2022Date of Patent: September 2, 2025Assignee: Koki Holdings Co., Ltd.Inventors: Yuji Kishima, Takuya Kataoka, Kazuki Noguchi, Akihiro Kobayashi, Daisuke Nitawaki, Ibuki Kanda, Shingo Kosugi, Yoshiki Aoki

Publication number: 20240118014Abstract: Provided is an electric device made more convenient by being configured such that the temperature of a wide area in each accommodation section can be individually adjustable. In an electric device, a first refrigerant pipe is provided to a right-side member constituting a side surface of a first accommodation chamber, and a second refrigerant pipe is provided to a left-side member constituting a side surface of a second accommodation chamber. The first refrigerant pipe and the second refrigerant pipe are independent of each other. A regulating valve includes: a first regulating valve provided to the first refrigerant pipe, and a second regulating valve provided to the second refrigerant pipe.Type: ApplicationFiled: January 28, 2022Publication date: April 11, 2024Applicant: Koki Holdings Co., Ltd.Inventors: Yuji KISHIMA, Takuya KATAOKA, Kazuki NOGUCHI, Akihiro KOBAYASHI, Daisuke NITAWAKI, Ibuki KANDA, Shingo KOSUGI, Yoshiki AOKI
