Abstract
A door handle, to be attached to a door, includes an outer case, an inner case integrated with the outer case, and a pressure detector configured to detect pressure applied to the inner case. The inner case includes a recess in proximity to an end portion in a longitudinal direction, and the pressure detector detects a displacement of a first inner wall surface on a center portion side of the inner case in the recess, caused by the pressure applied to the inner case.

A door handle to be attached to a door, the door handle comprising:
- an outer case;
- an inner case integrated with the outer case;
- and
- a pressure detector configured to detect pressure applied to the inner case,
- wherein the inner case includes a recess in proximity to an end portion in a longitudinal direction,
- the pressure detector detects a displacement of a first inner wall surface on a horizontal center portion side of the inner case in the recess, caused by the pressure applied to the inner case,
- the pressure detector includes both a base portion directly or indirectly fixed to the first inner wall surface and a pillar portion protruding from the base portion, and detects distortion of the base portion, caused by a load applied to the pillar portion due to the displacement of the first inner wall surface,
- the pressure detector is disposed in the inner case so as to face a holding portion provided closer to the end portion than the recess such that the pillar portion faces the holding portion side,
- the base portion is fixed to the first inner wall surface through a fixing member,
- a tip of the pillar portion is held by the holding portion, and
- the pillar portion causes distortion in the base portion upon application of a load by the holding portion to the pillar portion due to the displacement of the first inner wall surface.
A door handle to be attached to a door, the door handle comprising:
- an outer case;
- an inner case integrated with the outer case;
- and
- a pressure detector configured to detect pressure applied to the inner case,
- wherein the inner case includes a recess in proximity to an end portion in a longitudinal direction,
- the pressure detector detects a displacement of a first inner wall surface on a horizontal center portion side of the inner case in the recess, caused by the pressure applied to the inner case,
- the pressure detector includes both a base portion directly or indirectly fixed to the first inner wall surface and a pillar portion protruding from the base portion, and detects distortion of the base portion, caused by a load applied to the pillar portion due to the displacement of the first inner wall surface,
- the pressure detector is disposed in the inner case so as to face a pedestal portion provided closer to the end portion than the recess such that the pillar portion faces the pedestal portion side,
- the base portion is fixed to the first inner wall surface at the horizontal center portion side relative to the recess in a longitudinal direction of the inner case,
- a tip of the pillar portion is held by the pedestal portion, and
- the pillar portion causes distortion in the base portion by being applied a load from the pedestal portion due to the displacement of the first inner wall surface.
A door handle to be attached to a door, the door handle comprising:
- an outer case;
- an inner case integrated with the outer case;
- a pressure detector configured to detect pressure applied to the inner case;
- a contact detector configured to detect a contact position of a user's hand with respect to the inner case;
- and
- a controller including a memory and a processor coupled to the memory and configured to correct, according to a distance between the pressure detector and the contact position detected by the contact detector:
- the pressure detected by the pressure detector or
- a threshold value of a pressure detection value for determining whether to perform a predetermined operation.
