Patent Application
20200398606
The present invention relates to a chalk holding apparatus, and more particularly to a chalk holding apparatus that has two ends to hold chalks, and has a bulging center portion so it is easier for the user to hold.
Various types of chalk holding devices have been disclosed in the prior art. Some are designed for use in a conventional manner by grasping the device in one hand held close to the writing surface. Examples include U.S. Pat. Nos. 2,205,907; 5,048,989; 4,468,146; 2,181,202; 5,779,381; 3,603,693; 332,157; and 354,311. U.S. Pat. No. 389,517 discloses a hand-held apparatus that holds three pieces of chalk parallel to one another for drawing lines in triplicate. Other specialized chalk holding devices are disclosed for use in marking livestock as disclosed in U.S. Pat. No. 332,157.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new chalk holding device. The inventive device includes an elongate shaft having a first end and second end to secure two different chalks. Furthermore, the center portion of the elongated shaft is bulging and slightly curves away from the longitudinal axis of the elongated shaft so it is easier for the user to hold the shaft. Also, the chalk holding device includes a tightening ring at each end to secure the chalk. The user can simply untighten the tightening ring to replace the chalk can when needed.
It is an object of the present invention to provide a chalk holding apparatus to hold chalks at both ends and the user can choose which end to use when needed.
It is another object of the present invention to provide a chalk holding apparatus with a bulging center portion so it is easier for the user to hold the apparatus.
In one aspect, a chalk holding device may include an elongate shaft having a first end, a second end and a bulging center portion that slightly curves away from a longitudinal axis of the elongated shaft. It is noted that the bulging center portion is configured to provide a comfortable holding portion for the user, so it is easier for the user to hold the apparatus.
Furthermore, a plurality of slits are formed on an outer surface of the elongated shaft to increase the comfortability for the user to hold the apparatus. Preferably, the length of the elongated shaft has is about 3-10 inches. Ideally, the length the elongated shaft is about 5 inches.
The chalk holding apparatus further includes a tightening ring at each of the first end and second end. In one embodiment, the tightening ring is configured to threadedly engage with the first end and the second end to secure the chalk at each end. It is noted that it is easy for the user to replace the chalk when needed. The user can simply untighten the tightening ring, replace the chalk, and secure the new chalk with the tightening ring again.
The chalk holding apparatus may further include a holding string disposed at a center portion of the shaft. In one embodiment, the holding string forms a string ring to enable the user's hand to go through so the user can hold the apparatus while the string ring is located at the user's wrist, so the apparatus will not fall off. Furthermore, when the apparatus is secured at the user's wrist, it is easy for the user to switch from the chalk at the first end to the second end, and vice versa.
The detailed description set forth below is intended as a description of the presently exemplary device provided in accordance with aspects of the present invention and is not intended to represent the only forms in which the present invention may be prepared or utilized. It is to be understood, rather, that the same or equivalent functions and components may be accomplished by different embodiments that are also intended to be encompassed within the spirit and scope of the invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this invention belongs. Although any methods, devices and materials similar or equivalent to those described can be used in the practice or testing of the invention, the exemplary methods, devices and materials are now described.
All publications mentioned are incorporated by reference for the purpose of describing and disclosing, for example, the designs and methodologies that are described in the publications that might be used in connection with the presently described invention.

As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
As best illustrated in
Furthermore, a plurality of slits 114 are formed on an outer surface of the elongated shaft 110 to increase the comfortability for the user to hold the apparatus 100. Preferably, the length of the elongated shaft 110 has is about 3-10 inches. Ideally, the length the elongated shaft 110 is about 5 inches.
The chalk holding apparatus 100 further includes a tightening ring 120 at each of the first end 111 and second end 112. As shown in
The chalk holding apparatus may further include a holding string 130 disposed at a center portion of the shaft 110. In one embodiment, the holding string 130 forms a string ring 131 to enable the user's hand to go through so the user can hold the apparatus 100 while the string ring 131 is located at the user's wrist, so the apparatus 100 will not fall off. Furthermore, when the apparatus 100 is secured at the user's wrist, it is easy for the user to switch from the chalk at the first end 111 to the second end 112, and vice versa.
Having described the invention by the description and illustrations above, it should be understood that these are exemplary of the invention and are not to be considered as limiting. Accordingly, the invention is not to be considered as limited by the foregoing description, but includes any equivalent.
