A chuck (4) for grasping a writing lead and a rotor (6) arranged to be movable together in a direction of rotation and an axial direction within a body cylinder (1) are provided. A rotational drive mechanism for the writing lead is formed such that first and second cam faces (6a) and (6b) are respectively formed at one end face and another end face of the rotor in the axial direction, and first and second fixed cam faces (13a) and (14a) are arranged on the body cylinder side to face the above-mentioned first and second cam faces respectively. Retreat operation and forward movement (cushion action) of the writing lead by writing pressure are provided with a damping effect by sticky grease (19) interposed between a stopper (16) and a torque canceller (17). As a result, a sense of uncomforting, when writing, generated in conjunction with the cushion action can be reduced.

The pencil has a lead brake (4) with a cylindrical clamping body (7) for receiving and clamping a lead and axially penetrated from a bore hole (6). A sliding body is provided for axial guidance of the lead brake into a sliding area (3) of the pencil. The sliding body is designed as a sliding ring, which encompasses the clamping body with a radial distance, and is connected with the clamping body via through holes (23) between free radial bars. A radial distanced projection is arranged at an outer side of wall segments of the sliding ring that extends between the adjacent bars.

Die Erfindung betrifft einen mechanischen Stift, insbesondere einen mechanischen Bleistift, mit einem Vorschubmechanismus für Minen, einem mit einer Spitze (1a) versehenen Schaft (1b) und einer Minenbremse (4), wobei die Minenbremse einen im wesentlichen zylindrischen, von einer Bohrung (6) axial durchsetzten, zur Aufnahme und zum Festklemmen einer Mine dienenden Klemmkörper (7) und einen gegenüber diesem radial erweiterten, zur axialen Führung der Minenbremse in einem Gleitbereich (3) des Stiftes (1) dienenden Gleitkörper aufweist. Der Gleitkörper ist als Gleitring (13) ausgestaltet, der den Klemmkörper (7) mit Radialabstand umgreift, und mit diesem über mehrere, Durchbrechungen (23) zwischen sich freilassende Radialstege (14) verbunden ist, wobei an der Außenseite von sich jeweils zwischen zwei benachbarten Stegen erstreckenden Wandsegmenten (24) des Gleitrings (13) jeweils ein radial abstehender Vorsprung (25) angeordnet ist.

Variations in the size of a stick-like object are accommodated, and abutments are urged to contact with the stick-like object with an appropriate pressure. A stick-like object feeding container is provided with: an outer sleeve 11 having a front spring shoe 11a formed on the internal circumference of the front portion of the outer sleeve; an inner sleeve 12 slidably inserted into the outer sleeve and having a rear spring shoe 12a provided on the outer circumference of the inner sleeve; a spring 13 abutting at its front and rear ends against the front spring shoe and the rear spring shoe, respectively, to bias the inner sleeve backward; a chuck 17 adapted to be capable of gripping, by its front end portion, the stick-like object inserted into the inner sleeve; and a chuck ring 18. A ring member 21 is interposed between the front end of the spring 13 and the front spring shoe 11a; elastic pieces 22 extending along the stick-like object are linked at the rear end to the ring member; abutments 23 are formed on the front end of the elastic pieces; and the elastic pieces 22 are configured to elastically urge the abutments to contact with the stick-like object. The inner sleeve or chuck having fitted thereon the ring member is provided with engaging pieces for preventing the ring member from moving forward movement.

A mechanical pencil (10), includes an external cylinder (12), a lead delivery mechanism (20) disposed in the external cylinder, the lead delivery mechanism having a lead-fastening chuck (22) which fastens a lead and moves back and forth in the external cylinder to deliver the lead (40) toward a front end of the external cylinder, a lead holder disposed before the lead delivery mechanism in the external cylinder to gently hold a lead (40), and a guide member arranged between the lead-fastening chuck and the lead holder in the external cylinder and always urged backwardly toward the lead-fastening chuck to protect a lead portion between the lead-fastening chuck and a lead holding portion of the lead holder.
摘要:
A mechanical pencil for using a lead effectively includes a tip pipe (12) for protecting a lead. The tip pipe is mounted to a front end portion of the mechanical pencil so as to be able to axially project from or retract into a tip opening of the front end portion of the mechanical pencil. The tip pipe (12) is preferably made of metal and, at least one slit (12a) (and preferably two slits) axially extending from the tip, preferably is formed on the tip pipe so as to be mutually approximately in parallel. In the case of two slits, the two slits are arranged circumferentially at less than substantially 180E intervals and approximately in parallel with an axial direction and a portion between these two slits forms an elastic piece. Because the elastic piece of the tip pipe tends to move inwardly so as to make a surface contact against the lead, the force holding the lead is increased.

A container for extending a stick-shaped material comprises a tubular body (1) and a chuck (2) formed on the tubular body inserted into a chuck ring (3). The tubular body and the chuck ring are provided with first and second deflectable projecting parts (4,5) respectively, while a head member (6) is provided with first and second retaining holes (7,8) the first deflectable projections of the tubular body engage the first retaining holes, while the second deflectable projecting parts of the chuck ring engage the second retaining holes of the head member. A resilient elastic body (9) is mounted between the end of the head member and an elastic body bearing formed on the tubular body. A stick-shaped material such as a stick-shaped eraser (10) is held in the head member and the chuck. The tubular member, the chuck ring, the stick-shaped material and the elastic body are assembled as a unit with the head member. Therefore, the number of parts is reduced and assembly and disassembly becomes relatively easy.
摘要:
A chuck for a mechanical pencil, wherein a lead holding part (62) is formed with several teeth (63) for use in holding the lead under four-point or six-point contacted condition. In this manner lead dust discharging regions are made. The extremity end (41) of the lead supplying cylinder is abutted against the rear raised surface (601) of the flange part (6a) from the rear end side of the lead chuck, forced applied from both directions when the front raised surface (602) of the flange part (6a) receive the rear end of the resilient member (12) installed between it and the sleeve (7) are utilized and each of the chuck members (61) generates a flexing phenomenon and then the chuck members may perform an instantaneous expanding operation under this flexing force.
