A molten gold writing apparatus that includes a barrel extending from a top end to an open bottom end. A heating element is positioned within the barrel and includes a rechargeable battery. A cartridge includes a refillable chamber configured to hold a solid gold refill and dimensioned to fit within the heating element. The heating element melts the gold refill and allows it to flow to a tip end of the cartridge. A grip is configured to selectively engage the bottom end of the barrel to cover all but the tip end of the cartridge.

Convertible writing instrument assemblies are provided, including an outer barrel having a tapered nosecone with an aperture for a writing instrument tip and a grip portion, and an aperture for receiving an eraser or a push button therethrough, wherein the writing instrument assembly provides selective access to a volume defined by the outer barrel, and wherein the outer barrel and the volume are collectively configured to operably and interchangeably receive a mechanical pencil insert having the eraser and a retractable pen insert having the push button. Mechanical pencils and pens utilizing the convertible writing instrument assemblies are also provided, along with kits for providing such mechanical pencils and pens.

A pen for cosmetic, writing, drawing, sketching and/or marking purposes includes an inner part and an outer part, wherein at least a portion of the inner part is accommodated in the outer part and is fastened therein. A fastening device between the inner part and the outer part serves to fasten the inner part to the outer part, wherein the fastening device is elastically deformable and is deformed in the installed state against its elastic restoring force. The fastening device is supported between the inner part and the outer part by the elastic restoring force to fasten the inner part to the outer part.

A writing implement includes: a barrel; a writing body supported by the barrel so as to be relatively movable with respect to the barrel in an axial direction thereof, whereby the writing body is projected from and retracted into a front end of the barrel; a rotation member disposed in the barrel so as to be relatively rotatable with respect to the barrel about an axis thereof, the rotation member being provided with a groove or a slit that helically extends about the axis; and a pressing unit having a moving unit that moves in the groove or the slit, the pressing unit being relatively movable with respect to the barrel in the axial direction, while its relative rotation about the axis being restricted; wherein the pressing unit can be pressed forward with respect to the barrel.

An improved double-locking clicker mechanism is generally disclosed. The clicker mechanism includes a housing, plunger, and lock button. The lock button interacts with the housing such that it is capable of locking the plunger in two positions: a retracted mode and an extended mode. The clicker mechanism can couple with other elements to form a functional structure, such as forming part of a writing tool. With such a structure, the writing tool can be locked in writing and non-writing modes, providing improved safety for users thereof.

The adaptation of a pocket-size pen for use by a person is provided. The pen includes a cap with internally configured male threads, and a body. The body includes a barrel with externally configured and spaced apart first set of female threads, and second set of female threads. The barrel is hollow inside with a top opening for receiving a full-sized standard ink source. The male threads of the cap engage the second set of female threads of the pen body for closing a writing tip and reducing the length of the pen for storage in the pocket of a user. The male threads of the cap engage the first set of female threads of the body for transforming the pen into an extended-length pen similar in length to a conventional pen and revealing the writing tip for comfortable writing using the pen.

A writing instrument includes a body, a nosecone, and an adaptor each being of generally hollow tubular shape. The body, the nosecone, and the adaptor each have a first end and a second end. The first end of the adaptor is configured to slidably couple to the nosecone second end. The second end of the adaptor is coupled to the first end of the body. The writing instrument includes a writing element with a mounting end and a writing end where the mounting end is removably coupled to the second end of the body. The writing instrument includes a locking mechanism configured to selectively lock the nosecone in a storage position or a writing position. In the storage position, the nosecone extends and covers the writing end. In the writing position, the nosecone retracts and the writing end of the writing element extends beyond the nosecone.

A writing implement includes: a barrel; a writing body supported by the barrel so as to be relatively movable with respect to the barrel in an axial direction thereof, whereby the writing body is projected from and retracted into a front end of the barrel; a rotation member disposed in the barrel so as to be relatively rotatable with respect to the barrel about an axis thereof, the rotation member being provided with a groove or a slit that helically extends about the axis; and a pressing unit having a moving unit that moves in the groove or the slit, the pressing unit being relatively movable with respect to the barrel in the axial direction, while its relative rotation about the axis being restricted; wherein the pressing unit can be pressed forward with respect to the barrel.

Disclosed is a pen for writing, referred to as a palm pen herein because the body of the pen fits into the palm of a human hand. The palm pen can include a spherically shaped body, and an ink delivery system. The ink delivery system can include a tip having an end connected to the body and an opposite end comprising a nib, an ink conduit having an end coupled to the nib within the tip and an opposite end extending inside the body, and a first ink cartridge fluidly coupled with the opposite end of the ink conduit and contained within the body. The ink delivery system can additionally include a cartridge holder having an active cartridge slot for the first ink cartridge and cartridge storage slots for storage of additional ink cartridges.

A compact writing instrument includes a barrel and a cap. A majority of a length of the barrel and a writing element carried thereby may be received by the cap when the barrel and the cap are placed in a stored position, providing a compact stored arrangement. The cap may be secured to the barrel in a writing arrangement that extends a length of the writing instrument significantly; for example, to a conventional writing instrument length. Engagement features of the cap and barrel may include steep threads that enable the cap to be assembled with and disassembled from the barrel with one rotation (360°) or less. A clip on the cap may include a closed end that defines a receptacle, with the closed end and receptacle extending beyond a corresponding end of the cap. In addition, the closed end and receptacle may extend partially over the corresponding end of the cap.
