Abstract: The present invention provides writing instruments having a mechanism for extending and retracting a writing tip and advancing a lead by rotational operation. The writing instrument is comprised of a front tubular member (1); a front inner tubular member (2) disposed within the front tubular member (1); a refill (3) inserted into the front inner tubular member (2); and a driver (10) mounted in the front tubular member (1) and the front inner tubular member (2). The driver (10) is allowed to rotate but not be axial displaced relative to the front tubular member (1) and the front inner tubular member (2). A rear tubular member (5) is detachably connected to the driver (10) so as not to allow rotation relative to the driver (10). A rear inner tubular member (4) is inserted in the driver (10). The rear inner tubular member (4) and the driver (10) interengage with each other by engagement between at least one axial groove (11) and corresponding projections (12).

Abstract: A rotary-cam ball-point pen having an outer sleeve, a rotary-cam mechanism comprised of a cam body provided on the inside of the outer sleeve, a rotary-cam engaging the cam body, and a cam bar engaging the rotary-cam, and a refill. The rear portion of the refill is loaded backward by an elastic body inserted into the rotary-cam. The cam bar has a structure with flexibility in which the cam bar can be distorted inward by applying a radial force. Since the cam bar is inserted into the outer sleeve from the rear side of the outer sleeve, it is possible to form a clip of an integral part of the cam bar, or a decoration having dimensions larger than the outside diameter, or a knocking cap.

The decoration body is rotatably connected to a handle assembly for a writing core through a decoration core extending in the axis of and within the fixed element.

Abstract: A writing instrument includes a reservoir, a barrel in which the reservoir is received for a longitudinal displacement between a retracted position and a writing position, a push button for actuating the reservoir, and a shift device for moving the reservoir between the positions in which the reservoir is latchable with spring biasing. The shift device has a controlling curved portion arranged fixedly in the barrel and a movable actuating device, the actuating device including the push button and at least one elastically deflectable shift rod arranged to latch with the insert and unlatch from the latter so that latching and unlatching movements of the shift rod are associated with different planes.

Abstract: A cosmetic applicator such as a lipbrush is provided with an actuator which includes a tab part locating in and extending outwardly of a slot formed in an applicator barrel. By the sliding of the tab between opposite extreme ends of the slot, a lipbrush element is retracted or extended from within the barrel.

Abstract: A writing tool such as a ball pen or the like including an openable decorative article at a shaft end comprises a shaft member serving as a casing for the writing tool, a core vertically displaceably received in the shaft member, an actuation member connected to the core, a movable member adapted to move when the core is downwardly displaced at the time of practical use of the writing tool, and a support member for supporting the decorative article. The actuation member includes a fixing piece and an actuation piece protruded outside of the shaft member. When an user displaces the actuation piece in the downward direction with his finger for practical use of the writing tool, an assembly of the movable member and the support member is displaced in the same direction, whereby the decorative article is expanded via a flange integrated with the support member as if petals of a flower are opened. At this time, a butterfly-shaped accessory fixedly mounted on the central part of the support member appears.

Abstract: A fingertip-receiving pen includes a short hollow penholder for receiving a finger and a writing element coupled with a compression spring and attached to a socket within the penholder. The socket includes a unitary resilient hook member which can be forced to be seated in a hole extending through the side wall of the penholder so that the writing element can be firmly positioned when it is pushed by a finger to protrude beyond the front through-hole of the penholder. As soon as the resilient hook member is pressed to disengage the penholder from within the hole, the writing element is immediately pushed by the compression spring to completely move back inside the penholder so that the pen conveniently can be carried by oneself.

Abstract: A special container for storing and dispensing nail polish includes a brush applicator unit that is movably mounted on the cap unit of the container. The brush unit is moved by depressing a button on the cap, and a stop means is included in one embodiment to hold the brush in the retracted and in the extended positions.

Abstract: A feed mechanism for a writing device comprising a writing medium carrier which is displaceable in a housing in a front and rear position by means of a press button. Connected with the press button is a rotatable switching element which comprises a circulating switching cam in which a carrier element engages. A spring is arranged between the carrier element and a locking element, and the locking element comprises a spring arm with a supporting surface which engages in an opposed surface at the housing.

Abstract: In a writing instrument with a pressure mechanism for the movement of a writing element (4, 5, 6, 11, 12, 13) against spring pressure from a retracted position of rest into an advanced writing position, in which retention by means of a retention element (18, 19, 20) takes place, the retention element (18, 19, 20) has a cup section (18) open towards the rear. In this cup section is a ball (23) of magnetizable material which is axially freely movable back and forth in the cup section. Adjacent to the opening of the cup section (18) is a permanent magnet (16), the front face of which forms a concave contact surface (17), disposed coaxially to the writing element (4, 5, 6, 11, 12, 13) for the placement of the ball (23).

Abstract: A ball-point pen is disclosed, having a push button which can be displaced to a limited extent in longitudinal direction of the ball-point pen housing so as to extend the cartridge which is urged by spring in the inward direction, and having a detent means for locking the inwardly-pushed position of the push button. In order to obtain a simple structural form as well as a mechanism which operates trouble-free, it is proposed that the push button be developed as a slide plate and have on its wide side a tongue cut therefrom which extends resiliently transversely out of the wide side and bears the detent tooth of the detent means.

Abstract: A retractable mechanism for a writing element especially the expendable refill of a ball-point writing pen, is disclosed. A manually depressible plunger (4) advances a latch member (7) biased to retract the plunger (4). The latch member (7) has a pair of latch arms (11,12) one of which in an advanced or retracted position thereof engage a latch means (5,6). Depression of the plunger (4) releases the engaged latch arm (11 or 12) from its latch means (5,6). The resultant of the force on the plunger (4) and bias on the writing element (1) then laterally aligns the other latch arm (12 or 11) with its latch means (6 or 5). On release of the plunger (4), the bias on the writing element (1) brings a co-operating notch (16) and pivot edge (15) of the aligned latch arm (11,12) and latch means (5,6) into register for pivot action therebetween.

Abstract: The present disclosure provides an integrant drive member for converting oscillating to reciprocating motion in a hand-held implement of the type having an elongate housing with an axially oscillable cap and a longitudinally reciprocal unit. The drive member comprises a pair of coaxial sleeve sections connected by a pair of links. One sleeve section is oscillable conjointly with the cap and the other is reciprocal conjointly with the unit. The links are pivoted at points defined by thin flexible webs formed at generally diametrically opposed positions on contiguous surfaces of the sleeve sections. Upon conjoint oscillation of the cap and the one sleeve section, the links swivel on the webs around the pivot points between folded and erect positions and reciprocate the other sleeve section and unit conjointly between retracted and extended positions.

Abstract: A writing instrument having a plurality of writing medium assemblies which can be separated into a plurality of writing instruments each having at least one writing medium assembly. The writing instrument may include writing medium assemblies which are all retractable, all fixed or both retractable and fixed. Regardless of whether the writing instrument has a single or plurality of retractable writing medium assemblies, only one positioning device is required to position the writing medium assemblies in writing position.

Abstract: A writing appliance with a retractable stylus actuated into operating position by a reciprocable member against the bias of a spring. The stylus is latched in operating position by a slender elongated flexible member under tension, the flexible member being attached at the outer end with reciprocable member and having at the inner end a cam follower for interaction with a cam surface and a recess on a projection on the inner wall of the shell of the appliance, the flexible member remaining laterally deflected while latched. Upon subsequent reciprocation of the operating member, shaped surfaces on the cam follower and projection guide the inner end of the flexible member around the projection under the stored resilience of the flexible member and the bias of the spring. A guiding arrangement to insure interaction between the cam follower and the projection includes a key on the flexible member which snaps into a slot in the wall of the shell when the stylus is inserted into the shell.
