A damper is provided which can more reliably prevent malfunction and breakdown and which enables efficiently performing repair and inspection operations. This damper, provided with a casing linked to a first object and a rotating part linked to a second object rotatably attached to the first object, damps rotation in either the direction closing or the direction opening the second object, and is provided with a sensor which detects prescribed change in the external environment in the damper or around the damper, and a control unit which externally communicates, over a communication network, information relating to the change in the external environment detected by the sensor, wherein the sensor is configured from at least one of: a rotation sensor for detecting the number of revolutions of the rotating part; a sound sensor for detecting sound during rotations of the rotating part; a temperature sensor for detecting temperature; and a torque sensor for detecting torque on the basis of friction during rotation of the rotating part.

This is the U.S. national stage of application No. PCT/JP2018/034812, filed on Sep. 20, 2018. Priority under 35 U.S.C. § 119(a) and 35 U.S.C. § 365(b) is claimed from Japanese Application No. 2017-184237, filed Sep. 25, 2017, the disclosure of which is also incorporated herein by reference.
The present invention relates to a damper that damps rotation of a second object rotatably attached to a first object in either a closing direction or an opening direction, and a damper monitoring method.
There has been known a technique concerning a damper that includes a casing linked to a first object, and a rotational part linked to a second object rotatably attached to the first object, the damper damping the rotation of the second object in either a closing direction or an opening direction (c.f. Patent Literature 1).
FIG. 1 is a right side view showing a box member provided with a damper according to an embodiment of the present invention.
FIG. 2 is a block diagram showing the damper.
FIG. 3 is a perspective view showing the damper.
Next, a damper according to an embodiment of the present invention will be described with reference to FIGS. 1 to 7.
The damper damps the rotation of a second object rotatably attached to a first object in either a closing direction or an opening direction.
Specific examples of the use in which the damper is provided include: a use for damping the rotation in the closing direction of an original pressing plate rotatably attached to the body of a multi-function machine which includes an original reader; a use for damping the rotation in the closing direction of a hatch (lid) configured to exchange a toner cartridge rotatably attached to the body of a printer; a use for damping the rotation in the closing direction of a screen part rotatably attached to the body of a laptop computer or a mobile phone; a use for openably linking a hood rotatably attached to the body of a car; a use for damping the rotation in the closing direction of a toilet seat rotatably attached to a toilet; a use for damping the rotation in the closing direction of a lid rotatably attached to a pot of a rice cooker; and a use for damping the rotation in the closing direction of a window or a door rotatably attached to an opening that communicates with the inside of a furnace or a workroom.
