Abstract: To make it easier to lift and move a wheelchair by keeping casters from hanging even when the wheelchair is lifted by one hand, a wheelchair includes a folding mechanism that couples a left-side support arm and a right-side support arm foldably in a left-right direction of the vehicle body. The folding mechanism includes an operation part for use in changing a state of a left-side support arm and a right-side support arm from one of a folded state or an unfolded state to another. The operation part is arranged between a rear drive wheel and a caster in a side view of the vehicle body.

Abstract: To facilitate unfolding of a wheelchair outside a vehicle by a simple one-handed operation even in a seated state on a driver's seat of the vehicle, a wheelchair includes an upper support arm and a lower support arm, each of which couples a left side frame and a right side frame and is folded in an up-down direction in a central portion thereof in a left-right direction. A tensioning member having a flexibility is coupled to the upper support arm and the lower support arm; and a grip section is attached to the tensioning member. The upper support arm and the lower support arm, when each of which is in a folded state, are urged in an unfolding direction by a predetermined tensile force input to the tensioning member.

Abstract: To improve body rigidity during unfolding of a foldable wheelchair, a wheelchair includes a support arm 40 that couples a left side frame and a right side frame and is folded in a central portion in a left-right direction; a footrest that couples a front end portion of the left side frame and a front end portion of the right side frame and is folded in a central portion in the left-right direction; and a rod that connects the central portion of the support arm in the left-right direction and the central portion of the footrest in the left-right direction.

Abstract: A folding wheelchair which prevents unexpected unfolding includes an upper support arm and a lower support arm coupling a left side frame and a right side frame foldable in an up-down direction in central portions thereof in a left-right direction. An engaged section is provided in at least one of the upper support arm and the lower support arm. An engagement section engages the engaged section to prevent relative displacement in the up-down direction of the central portions of the upper support arm and the lower support arm in the left-right direction. An operation section switches operation of the engagement section from an engagement state with the engaged section to an unengaged state.

Abstract: To facilitate attachment of a seat and suppress rattling of the attached seat, a seat frame is provided with a frame abutment section that abuts a side frame from one side in a left-right direction; an abutment member that abuts the side frame from the other side in the left-right direction; and a shaft member that supports the abutment member in a manner to allow rotation thereof about an axis extending in a body front-rear direction with respect to a body portion of the seat frame. The side frame includes a convex section that protrudes upward, the convex section pressing the abutment member from below during attachment of the seat frame and thereby causing the abutment member to rotate in a direction in which a portion of the abutment member below the axis abuts the side frame.

Abstract: It is an object to make it easy to unfold a wheelchair simply by lifting a part of the wheelchair with one hand. A wheelchair includes a folding mechanism that folds a left-side support arm and a right-side support arm. The folding mechanism includes a grip part coupled to the distal end part of the left-side support arm and the distal end part of the right-side support arm. The grip part extends in the pivoting direction of the left-side support arm and the right-side support arm at a time of switching from a folded state to an unfolded state.

Abstract: To provide a measurement apparatus capable of simplifying a test configuration and reducing cost. A measurement apparatus includes a measurement unit 2 that measures an RF signal received from a DUT 20, a signal generation unit 3 that generates and transmits a test RF signal to be transmitted to the DUT 20, and a 1-PPS signal generation unit 4 that generates a 1-PPS signal for synchronization of transmission/reception timing between the measurement unit 2, the signal generation unit 3, and the DUT 20, and outputs the generated 1-PPS signal to each of the measurement unit 2, the signal generation unit 3, and the DUT 20.

Abstract: The wheelchair includes a seating portion, body frames that support the seating portion, wheels that are rotatably supported by the body frames, an engaging portion, a left brake that brakes a left rear wheel, and a coupling portion that couples the engaging portion and the left brake to each other. The engaging portion is capable of switching between an engagement attitude for engaging a vehicle body member that forms an opening of a vehicle and a disengagement attitude for releasing the engagement with the vehicle body member. The coupling portion transmits the movement of the engaging portion to the left brake when the engaging portion makes an attitude change from the disengagement attitude to the engagement attitude. This operates the left brake when the attitude of the engaging portion switches from the disengagement attitude to the engagement attitude and brakes the left rear wheel.

Abstract: A wheelchair includes a seating portion on which a wheelchair user sits, a body frame that supports the seating portion, a pair of rear wheels and a pair of front wheels rotatably supported by the body frame, and a seat back portion capable of changing the inclination angle with respect to the seating portion. The wheelchair includes push-along handle portions as engaging portions capable of fixing the seat back portion to a side sill as a vehicle body member that forms a door opening of the vehicle when the seat back portion is tilted backward of the wheelchair.

Abstract: When a start condition determined in advance is satisfied while a vehicle is parked, a controller controls an aircraft such that the aircraft takes off from the vehicle, a photographing unit captures a position notification image including at least the vehicle and notifying a parking position of the vehicle, and the position notification image is transmitted to a mobile terminal having a display unit and carried by a user outside the vehicle.

Abstract: It is an object to improve riding comfort of a wheelchair having a folding mechanism by keeping an operation part of the folding mechanism from contacting a wheelchair user seated. A folding mechanism includes an operation part for use in changing a state of a left-side support arm and a right-side support arm from one of a folded state or an unfolded state to another. The operation part is arranged below an upper end part of a seat frame with a predetermined space therebetween.
