摘要： A mechanical pencil is disclosed in which lead feed occurs automatically upon lifting of the pencil from the paper surface or the like and in which the slider can be locked in a retreated position when the pencil is not in us. The mechanical pencil includes a tip member fitted in the front end of a shell removably, a sleeve disposed slidably in the interior of the tip member, a lead feed mechanism which is mounted in the interior of the sleeve and which permits a forward movement of a lead but inhibits a backward movement of the lead, an ejection bar mounted on the front end side of the sleeve, with the lead extending through the ejection bar, a slider disposed slidably within the tip member and having a locking engaging portion capable of engaging the tip member disengageably, the slider imparting a predetermined frictional force to the lead, and a resilient member disposed between the slider and the ejection bar, the resilient member having an urging force stronger than a lead gripping force of the lead feed mechanism under.

摘要： A lead chuck of a mechanical pencil to be assembled into a lead feeding mechanism of a rear end knock type, an automatic lead feeding type and an extremity end knock type mechanical pencil in which it is arranged within the sleeve through a resilient member in such a way as it may be advanced or retracted. A lead holding part is formed at the extremity end portions of the divided surfaces of the chuck members which are fully divided into two sections along an axial plane. The lead holding part is formed with several teeth for use in holding the lead under four-point or six-point contacted condition within axially formed grooves made at the central portions of the divided surfaces. The teeth are projected in several rows and formed at the raised surfaces of the grooves. Stepped partial circumferential projections are projected and formed at the central part of the raised parts of the front portions of the semi-circumferential flange which are projected and formed at the outer circumference at the rear ends of the chuck members. Other stepped projections are formed at both end portions of the raised rear surfaces of the opposite sides of the flange, thereby the extremity end of the lead supplying cylinder extremity end receiving element is abutted against the rear raised surface of the flange part from the rear end side of the lead chuck. Forces applied from both directions, when the front raised surface of the flange part receive the rear end of the resilient member installed between it and the sleeve, are utilized and each of the chuck members generates a flexing phenomenon and the chuck members may then perform an instantaneous expanding operation under this flexing force.

摘要： A bar extruding implement extrudes a bar, such as a lead, a lipstick or the like, gradually and is capable of automatically ejecting a marginal portion of the bar. A projection formed on a sliding member inserted in an inner tube slides along a helical groove formed in the inner circumference of a barrel to advance the sliding member when a rotational operating head is turned to turn the inner tube in one direction, whereby a bar holder holding a bar is advanced gradually toward the front end of the barrel to extrude the bar from the front end of the barrel. Upon the arrival of the bar holder at a disengaging position, the sliding member is disengaged from the bar holder and advances forward through the bar holder when the inner tube is turned further after the bar holder has arrived at the disengaging position to eject a marginal portion of the bar remaining on the bar holder.

摘要： A lead feed mechanism for a mechanical pencil, in which a lead protruded by a certain length from a lead protection pipe housed in a bottom member attached at the bottom of the pencil is fed together with the pipe, and which comprises a lead chuck which is split in plural parts along the axis of the pencil and whose bottom sections pinch the lead on its outside circumferential surface. A sleeve contains the lead chuck so as to urge the lead chuck upwards by an elastic member. The sleeve includes an engaging portion provided on the inside circumferential surface of the top portion of the sleeve and engaged with an engaging portion provided on the outside circumferential surface of a bottom bearer for a lead pipe in which a spare lead is housed. A frame is provided around the sleeve which is fitted on the bottom with a pushing member which bears by the open top of the frame an elastic member provided between the bottom bearer and the frame. A slider is fitted in a cylindrical fixed member fixed in the bottom member so that the slider can be slid by the action of an elastic member. The top of the slider is separated at a prescribed distance from the pushing member.
