A striking tool restricting movement of an intermediate member toward a striker reliably prevents no-load strokes. A hammer drill includes a cylindrical tool holder holding a tip tool, a motor, a piston that reciprocate with rotation from the motor, a striker that reciprocate in cooperation with the piston, an intermediate member reciprocably accommodated in the tool holder between the striker and the tip tool and in contact with a rear end of the tip tool at a normal strike to indirectly transmit a strike from the striker to the tip tool, and at least two ring members that move in a front-rear direction accommodated in the tool holder at a front of the intermediate member between the tool holder and the intermediate member. At least one ring member is made of metal.

A hydraulic, pneumatic, gasoline, diesel, or electric tool may include a spindle that is adapted for rotational movement. A swing arm may be coupled to the spindle such that rotational motion of the spindle is transferred to the swing arm. The swing arm makes contact with a piston such that the rotational motion causes the piston to move along a linear path. The piston may interact with an energy storage medium when the swing arm moves the piston in the first direction, causing energy to be stored in the energy storage medium. As the swing arm continues to rotate, the swing arm may lose contact with the piston, thus allowing the energy storage medium to urge the piston in a second direction opposite the first direction to strike an anvil. The swing arm may be a multiple roller swing arm. The energy storage medium may be a compound spring assembly.

A power tool, in particular a rotary hammer or combination hammer, containing a percussion-mechanism apparatus for generating percussion pulses on a tool, having a basic body for receiving a rear end of the tool, at least one first and second locking element, each arranged lying in radial openings of the basic body in a reversible manner in a locking position or release position, wherein, in the locking position, the rear end of the tool is held in the basic body and, in the release position, the rear end of the tool can be removed from the basic body, a locking ring for holding the at least first and second locking elements in the locking position, and a press-on element for guiding the at least first and second locking elements in a first axial direction and a second axial direction. The press-on element consists at least partially of an elastic material.

To reduce size increase, a power tool includes a motor, an output shaft located frontward from the motor, rotatable by the motor, and having an insertion hole extending rearward from a front end of the output shaft, a bearing supporting the output shaft in a rotatable manner, a locking member supported by the output shaft and movable to a locking position for locking a tip tool placed in the insertion hole and to an unlocking position for unlocking the tip tool, a bit sleeve surrounding the output shaft, and movable to a movement-restricting position for restricting radially outward movement of the locking member and to a movement-permitting position for permitting radially outward movement of the locking member, and an operable member operable to move the bit sleeve and at least partly overlapping the bearing in an axial direction.

A percussion device including a shank adaptor, a machine housing that contains a percussion piston that is arranged to carry out a reciprocating movement caused by the pressure from a hydraulic fluid and to strike the shank adaptor when the percussion device is in use. An elastic element is arranged radially outwards from the percussion piston to dampen the recoil from the shank adaptor. The machine housing has an inner surface that faces the percussion piston. The elastic element has an inner surface that faces the percussion piston and an outer surface that faces the inner surface of the machine housing. At least a part of the outer surface of the elastic element directly faces the inner surface of the machine housing.

[PROBLEM TO BE SOLVED] To provide an emergency escape method for a vehicle and an emergency escape device therefor, capable of escaping from the vehicle reliably and safely when, for example, the vehicle employing a laminated glass is submerged or when, for example, occupants of the vehicle are trapped within the vehicle because of a traffic accident, or the like by selecting various escape methods that can be taken in an emergency and realize a rational escape method.

[SOLUTION MEANS] It is an emergency escape method for a vehicle having a laminated glass 40 as a vehicle glass.

Piecing the laminated glass 40 at a predetermined area, cutting or crashing thereof, and fusing or shaking thereof.

After performing one or more of those emergency operations, pushing outward the laminated glass 40 by pressing the same at a position apart from the operating position.

Forming an escaping space 48 between the operating position and an attaching part of the laminated glass 40.

Occupants can escape through the escaping space 48.

A striking cap that may include a distal end configured to strike a foreign object. The striking cap may also include a proximal end opposite the distal end. The proximal end may include a protruding ring, where the protruding ring forms a cavity. The cavity may be configured to enable the striking cap to be attached to a striking implement. The proximal medial edge of the protruding ring may include a beveled surface.

An impact tool includes a motor, a driving mechanism, a tool body, an elastically-connected part elastically connected to the tool body to be movable at least in a front-rear direction relative to the tool body, a detecting mechanism configured to detect pressing of a tool accessory against a workpiece, and a control part configured to control driving of the motor based on a detection result of the detecting mechanism. The detecting mechanism includes a movable member that is provided in one of the tool body and the elastically-connected part and configured to be moved by relative movement of the other of the tool body and the elastically-connected part in the front-rear direction, and a detector that is provided in the one of the tool body and the elastically-connected part and configured to detect rearward pressing of the tool accessory by detecting movement of the movable member.
