Patent Document

BACKGROUND OF THE INVENTION 
     1) Field of the Invention 
     The invention herein relates to tape rule accessories, specifically a tape rule marking implement in which a support member is additionally mounted on the ruler blade output opening at the front end of a tape rule and a marking implement is installed on the corner at one side of its anterior extremity, thereby providing for convenient marking when measurements are taken as well as higher practical value. 
     2) Description of the Prior Art 
     When a conventional tape rule is used for taking measurements, the ruler blade of the tape rule is pulled out. If the user wants to indicate a certain measured position on the ground, wall, or other object surface, one hand typically maintains the tape rule in place, while other hand marks the appropriate point, resulting in inconvenient tape rule measuring. To enable more convenient tape rule utilization, the applicant of the invention herein conducted extensive research and development based on years of experience gained while engaged in the relevant industries, which following repeated testing and refinement culminated in the completion of the tape rule marking implement of the invention herein. 
     SUMMARY OF THE INVENTION 
     The primary objective of the invention herein is to provide a tape rule marking implement in which a support member is additionally mounted on the ruler blade output opening at the front end of a tape rule and a marking implement is installed on the corner at one side of its anterior extremity, thereby providing for convenient marking when measurements are taken, added tape rule application flexibility, and higher practical value. 
     To enable the examination committee a further understanding of the structural features, content, and advantages of the invention herein, the brief description of the drawings below are followed by the detailed description of the invention.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to FIG. 1, FIG. 2, FIG. 3, and FIG. 4, the tape rule marking implement of the invention herein is comprised of a tape rule  1 , a support member  2 , a marking implement  3 , and a carrier bracket  4 , wherein the tape rule  1  has a threaded hole  11  in one side at the lower edge of the front end and an extendible measuring ruler blade  12  disposed in the front end; the said support member  2  is of one-piece plastic construction and has an axial hole  21  formed horizontally through the upper edge of the posterior extremity, a marking implement holding recess  22  formed transversely through the center, an arcuate slot  23  formed along the bottom edge, and a cylinder-shaped marking implement locating mount  24  on the corner at one side of the anterior extremity, the said marking implement locating mount  24  having a containment passage  25  formed vertically through the center and, furthermore, a plurality of horizontal slots  26  formed along the circumferential center of the locating mount  24 , and the said support member  2  has a plurality of bumper cushions  27  attached to the lower edge of the anterior extremity. The marking implement of the  3  of the invention herein consists of a top cover  31  and a bottom seat  32 ; the said bottom seat  32  is of a cylindrical shape and has a containment passage  33  and a marking medium  34  is fitted into the underside of the said containment passage  33  and, furthermore, ink  35  is filled into the bottom seat  32  containment passage  33  such that the marking medium  34  absorbs the ink  35 ; additionally, the said marking medium  34  protrudes out slightly from the bottom seat  32 . A bearing shaft  41  is horizontally disposed at the upper edge of the carrier bracket  4  and, furthermore, the carrier bracket  4  has an elongated hole  42  formed in one side of the rear end that accommodates a mounting screw  44  inserted through a fixing button  43  that is fastened to the threaded hole  11  in one side of the lower edge at the front end of the tape rule  1 . The said marking implement  3  is inserted into the locating mount  24  containment passage  25  on the corner at one side of the anterior extremity of the marking implement  3 , the arcuate slot  23  formed along the bottom edge of the said support member  2  is slipped over the tape rule  1  ruler blade  12 , and the axial hole  21  formed horizontally through the upper edge at the posterior extremity of the support member  2  and the bearing shaft  41  horizontally disposed at the upper edge of the carrier bracket  4  are sleeved together, following which the mounting screw  45  and the bearing shaft  41  are fastened in place, enabling the assembly of the entire tape rule marking implement structure. 
     The marking implement support member  2  and carrier bracket  4  of the invention herein provide for assembly to the tape rule  1  by means of the threaded hole  11  in the lower edge at the front end of the tape rule  1 ; during the taking of measurements, when the user pulls out the ruler blade  12  to measure length and wants to designate a position, it is only necessary to press the marking implement to leave an indicatory spot; since the support member  2  is of one-piece plastic construction and, furthermore, has a cylinder-shaped marking implement locating mount  24  on the corner at the anterior extremity as well as a plurality of horizontal slots  26  formed along the circumferential center of the locating mount  24 , when the user applies downward force to press the marking implement, the said marking implement moves downward such that the marking medium  34  at the underside delivers a dot. When the user releases the marking implement, the marking implement automatically returns to its original position, resulting in enhanced user measuring and marking convenience as well as higher product practical value. 
     In summation of the foregoing section, since the spatial arrangement of the invention herein is original, capable of greater utility, and possesses exceptionally practical value and, furthermore, an identical or similar product has not been observed on the market, the present invention is submitted to the examination committee for review and the granting of the commensurate patent rights.
