Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a writing instrument cap holder for a writing instrument such as a felt tip pen, which prevents a cap covering the pen tip from accidentally dropping or being lost during use or the like. It is.

[0002]

2. Description of the Related Art A writing instrument such as a felt pen is provided with a cap for covering the pen tip when not in use. However, when the cap is removed during use, there is a place where the cap is temporarily placed. When the writing instrument is used indoors, it can be left in a suitable place on a desk or the like. However, when it is used outdoors, especially at a construction site, an appropriate place is often not found. On the other hand, a writing instrument in which a cap is integrally provided with a clip is also widely known. In such a writing instrument, the cap is detached from the pen tip at the time of use, and the clip is locked to an opening edge of a pocket or the like. This can prevent the cap from being lost, but many felt pens have a structure in which the cap is not provided with a clip.

[0003]

Therefore, for example, during the inspection work of each facility at a construction site, when marking is performed on a bolt or the like using the above felt pen,
Remove the cap from the tip of the felt tip pen and store it in the pocket of work clothes, or temporarily place it in an appropriate place around it, but at the height of bridge construction etc. or at the inspection site of elevator etc. Handling such a cap is extremely dangerous because the posture becomes unstable, and
Since the attention is concentrated on the feet, there is a risk that the cap may unexpectedly fall and be lost when the cap is removed or temporarily placed.

[0004] In this case, there is no problem if the cap can be used as a writing instrument even if the cap is lost, such as a ballpoint pen or a pencil. However, in a writing instrument such as a felt pen using volatile ink, the cap may be used. If lost, the ink volatilizes in a short time and cannot be used, and there is a problem that the ink has to be discarded. In addition, when performing a marking operation using a writing instrument such as a felt-tip pen, not only the cap but also the writing instrument itself may be accidentally dropped. However, there is a problem that the temperature is reduced.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to prevent a writing instrument or its cap from dropping at hand or from being lost during use or during use. It is an object of the present invention to provide a writing instrument cap holder that can reliably prevent the writing instrument from being caught.

[Means for Solving the Problems]

In order to achieve the above object, a cap holder for a writing instrument according to the present invention is provided, as described in claim 1, by attaching one end of a string to a base end of the writing instrument and attaching the one end of the string to the writing instrument. A cap of the writing instrument is attached to an intermediate portion in the length direction, and a loop for holding the string is formed at the other end of the string.

In the above-structured cap holder for a writing implement, the invention according to claim 2 is characterized in that a short cylindrical body for attachment to a base end of the writing implement is connected to one end of the cord-like object and the cord-like article is formed in a string form. A short tube for holding a cap of a writing instrument is attached to an intermediate portion in the length direction of the object.

Further, the invention according to claim 3 is characterized in that the holding loop formed at the other end of the string-like object is formed as a finger hook loop.

[0009]

When the writing implement is not used, a cap is placed on the tip of the writing implement so that the ink does not volatilize from the pen tip. When carrying in this state, even if the cap is accidentally detached from the writing instrument due to vibration or the like, since the cap is attached to the string connecting one end to the base end of the writing instrument, it may fall. There is no risk of loss or loss, and the cap can be immediately put on the writing implement.

In use, the cap is removed from the writing instrument, and the wrist or finger is inserted and locked into the loop formed on the other end of the string. In this state, the cap is supported on the hand side via the cord-like material, and there is no danger of falling or being lost. The writing operation can be performed, and the cap is held at a position separated from the pen tip of the writing instrument by pulling the cord-like object to the wrist side, and does not disturb the writing. In addition, even if the writing instrument is accidentally released during writing, the writing instrument is held on the hand side by the string-shaped object, and thus does not fall in a hanging state.

[0011] Further, at the time of inspection of equipment or the like, or at a construction site on a scaffold, the worker wears gloves to perform the work. In this case, the string-like material is inserted into the glove insertion port. If the loop is inserted and the loop is held by the tightening force of the glove, the writing implement and the cap can be prevented from dropping and losing as described above.

[0012] The above-mentioned writing tool cap holder is used to fix one end of the cord to the base end of the writing instrument with an adhesive or tape, and to attach the cap to the cord with an adhesive or tape. Although it may be performed, as described in claim 2, a short cylinder for attaching the string and a short cylinder for holding the cap are provided at one end of the string and an intermediate portion in the length direction thereof. By constructing the structure
By attaching the short cylinder for attachment to the base end of the writing instrument and inserting the cap of the writing instrument into the short cylinder for holding the cap, it is easy to attach the string to the writing instrument and to attach the cap to the string. Not only can you do
If the string is cut or the short cylinder is damaged, replace the cap with a new cap holder and attach the mounting short cylinder to the base end of the writing instrument. The structure which can prevent loss can be made.

In the case where the string is formed of a string or a string which does not have elasticity and the cap of the writing instrument is fixed to the string, the string attached to the base end of the writing instrument may be used. The length between one end and the cap mounting portion of the writing implement from this one end needs to be formed longer than the length of the writing implement. If it is attached so as to be slidable in the direction, it is only necessary to form the length of the cord-like object slightly longer than the length of the writing instrument. Then, with this configuration, when not in use, the cap is moved to the loop side of the cord and put on the pen tip of the writing implement, and when used, the cap is removed, and the cap is removed along the cord. It can be moved to one end side or the other end side. In this case, the string and the cap can be held at a position above the pen tip of the writing instrument, so that they do not hinder writing.

Further, the cord may be formed of a rubber cord capable of elastically expanding and contracting in the longitudinal direction. In this case, the cord is slid along the cap holding short cylinder. Not only can it be shortened as much as possible with the attached string, but also the cap can be firmly covered by the elastic tensile force of the string by extending the string and placing the cap on the writing instrument. And there is no danger of accidental escape.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a cap holder A of a writing instrument, and 1 is a braided or twisted yarn or a synthetic resin thread. As shown in FIG. 2, the length of the cord 1 is formed longer than the length of a felt pen B (hereinafter referred to as a writing instrument B). At the same time, the cap C of the writing implement B is attached to the middle part of the cord 1 in the longitudinal direction, and a thumb is inserted through the other end of the cord 1 so as to be locked.
Is formed by forming a holding loop 2 for holding the pressure.

The position at which the cap C of the writing implement B is attached to the cord 1 is such that the cap C is attached to the base end of the writing implement B so that the cap C can be attached to and detached from the pen tip. 1 is a portion having a dimension slightly longer than the length of the writing implement B from one end.

The manner in which the one end of the cord 1 is attached to the base end of the writing implement B and the manner in which the cap C is attached to an intermediate portion in the length direction of the cord 1 are integrated with an adhesive or an adhesive tape. Although it is possible to adopt a structure in which the writing instrument is fixedly attached or wound integrally with the thread, the cap holder of the writing instrument shown in FIG. A rubber or synthetic resin mounting short tubular body 3 made of rubber or synthetic resin to be removably fitted to the main body, and a rubber or synthetic resin made to detachably hold a cap C in an intermediate portion of the cord 1 in an inserted state. The cap holding short cylinder 4 is attached.

When the string-like object 1 is attached to the base end of the writing implement B, the short cylindrical body 3 is made of rubber and has an inner diameter slightly smaller than the outer diameter of the writing implement B to reduce its elastic force. The short cylinder 3 is formed so as to be fixed on the base end of the writing implement B by its elastic restoring force by fitting the short cylinder 3 on the base end of the writing implement B while expanding the diameter of the short cylinder 3 in opposition. In the case of synthetic resin, the inner diameter of the short cylinder 3 is formed to be equal to the outer diameter of the writing implement B, and the short cylinder is formed by the frictional force between the inner peripheral surface and the outer peripheral surface of the writing implement B. 3 may be formed so as to be held at the base end of the writing implement B.

As in the case of the short cylinder 3, the inner diameter of the holding short cylinder 4 of the cap C is made slightly smaller than the outer diameter of the cap C to make it elastically resilient. The cap C can be held by force, and if it is made of synthetic resin, it may be formed so as to be held by frictional force. However, if the cap C is formed in a truncated cone shape, The inner diameter of the opening at both ends is formed larger than the small-diameter distal end of the cap C and smaller than the large-diameter base end, which is the opening end of the cap C, and from one end opening toward the other end opening. It may be formed in a tapered frusto-conical shape.

The mounting structure of the short cylinder 3 for attachment and the short cylinder 4 for holding to the string-like object 1 is such that the short cylinder 3 The insertion support cylinders 3a and 4a each having a small diameter are integrally formed in the lengthwise direction, and the string-like object 1 is inserted through the insertion support cylinders 3a and 4a. Therefore, these short cylinders 3 and 4 are aligned in the length direction with the cord 1
It is mounted in a state where it is oriented in the length direction. The mounting short cylinder 3 to be attached to the base end of the writing implement B is formed as a bottomed short cylinder having one end open and the other end closed, and the base end surface of the writing implement B abuts against the inner bottom surface. It may be formed so as to be attached to the writing implement B so as to be in a state of being made.

The procedure of using the cap holder of the writing instrument constructed as described above will be described. The attaching short tubular body 3 attached to one end of the string-like object 1 is, as shown in FIG. The string-like object 1 is integrally attached to the writing implement B by being fitted to and fixed to the portion, and the writing implement B is attached to the holding short cylinder 4 attached to the intermediate portion in the longitudinal direction of the cord-like article 1. The cap C is inserted and held.

When the writing implement B made of a felt pen is not used, the ink storage chamber provided in the shaft of the writing implement B with the cap C over the pen tip of the writing implement B as shown in FIG. To prevent the volatile ink from volatilizing outside through the felt tip forming the pen tip.

Next, at the time of use, for example, when marking a bolt of equipment at a site where inspection of equipment and the like is performed, the cap C is removed from the tip of the writing implement B as shown in FIG. By exposing the pen tip and inserting and locking the thumb into a holding loop 2 formed on the other end side of the string-shaped object 1, the string-shaped object 1 is supported by the thumb, thereby holding the short tube. The cap C attached to the body 4 is drawn from the pen tip side of the writing implement B to the thumb side, and the marking operation is performed in this state.

At this time, since the cap C is attached to the cord-like material 1 via the holding short cylinder 4, there is no need to search for a place where the cap C is temporarily placed, and there is a risk that the cap C may fall or be lost. Instead, the marking operation can be performed immediately after the cap C is removed. Also, even if the writing implement B collides with another object and is released unexpectedly during the work, the writing implement B itself has its base end attached to the string-like object 1 and this string-like object 1 is used for holding. Since the writing tool B is supported by the operator's finger by the loop 2, the writing implement B is also reliably prevented from falling, and a situation in which the marking work or the like is interrupted does not occur, and therefore, the work efficiency can be improved.

At the time of inspection of equipment and the like, and at construction sites on scaffolds, workers wear gloves E in order to ensure safety. When using B, the other end of the string 1 is pulled by pulling the holding loop 2 of the string 1 to the wrist side and inserting it between the glove E and the wrist as shown in FIG. Gloves E
And the holding loop 2 is held by the elastic force of the glove E. Then, similarly to the above, not only the writing implement B and the cap C can be prevented from dropping or losing by the string-like object 1, but also the cap C removed from the pen tip of the writing implement B is largely drawn to the hand side. It doesn't get in the way and interfere with your work.

The holding short cylinder 4 for holding the cap C attached to the string 1 may have the insertion support cylinder 4a integrally provided on the outer peripheral surface thereof fixed to the string 1. However, when fixing, as described above, the fixing position is the string 1
The length of the cord 1 must be longer than the length of the writing tool B from one end of the writing tool B. Therefore, the length of the string-like object 1 is increased, and the short cylindrical body 4 for holding the writing tool B from the pen tip of the writing tool B is used. Since there is a possibility that the separation distance of the string-like object becomes short and the work becomes difficult, there is a possibility that the string-like object 1 may be moved as shown in FIG.
Is desirably slidable in the length direction of the cord-like object 1 in the insertion support cylinder portion 4a of the holding short cylinder 4 through which is inserted.

With this configuration, the length of the string-like object 1 may be formed slightly longer than the length of the writing implement B.
Then, after the mounting short tubular body 3 attached to one end of the string-like object 1 is fitted to and fixed to the base end of the writing implement B, the holding short tubular body attached with the cap C of the writing implement B is attached. 4 is slid to the other end of the string-shaped object 1 to cover the pen tip of the writing implement B with the cap C. When using, put cap C on writing implement B
The holding loop 2 formed at the other end of the string-like object 1 is detached from the pen tip and connected and locked to a finger or the like in the same manner as described above. 4
Is slid along the cord 1 toward the loop 2 of the cord 1 or the mounting short cylinder 3 attached to the writing implement B to be positioned near the hand.

Therefore, the cap C can be held at a position where it does not hinder the operation, and operations such as marking can be performed smoothly. The holding short cylinder 4 is held at a desired position by friction between the insertion support cylinder 4a and the string-shaped object 1. After use, the holding short cylinder 4 is slid and moved to the pen tip side of the writing implement B, and then the cap C held by the holding short cylinder 4 is put on the pen tip,
As in the above embodiment, the ink is prevented from volatilizing from the nib made of the felt tip.

Next, a string-like material having no elasticity is used as the string-like material 1. The string-like material 1 'is formed by a rubber string which can elastically expand and contract in the length direction. You may leave.
FIG. 7 shows an embodiment of the present invention, in which, similarly to the above-described embodiment, one end of the cord 1 'is made of rubber or synthetic resin which is detachably fitted to the base end of the writing implement B. And a rubber or synthetic resin cap holding short cylinder 4 for detachably holding the cap C in an inserted state is attached to an intermediate portion of the string-shaped object 1. I have. In this case, the cap holding short cylinder 4 has its insertion support cylinder 4a immovably fixed to the string-shaped object 1 '. It is a shorter position.

Further, since the string-shaped object 1 'is elongated, its length does not necessarily have to be longer than the writing implement B, and may be as long as or shorter than the writing implement B.
Furthermore, since the diameter of the holding loop 2 formed at the other end of the string-shaped material 1 'can be increased, if it is formed large enough to be fixed to a finger or the like by the contracting force of the loop 2, Good.

In the cap holder of the writing instrument thus constructed, the cap C is attached by fixing the short tubular body 3 for attachment to the base end of the writing instrument B and extending the cord 1 '. The holding short cylinder 4 inserted is attached to the writing implement B.
Then, the cap C is put on the pen tip. In this state, the cap C is pulled toward the base end of the writing instrument B by the elastic restoring force of the string-shaped object 1 ', and the inner peripheral surface thereof is strongly adhered to the distal end of the writing instrument B, and the cap C The airtightness of the inside is maintained, the volatilization of the ink can be reliably prevented, and the pen does not accidentally fall out of the tip of the writing implement B, and the pen tip is always covered when not in use.

In use, as shown in FIG. 8, the cap C is removed from the pen tip while the cord 1 'is extended, and the holding loop 2 formed at the other end of the cord 1' is similar to the above. To a finger or the like. At this time, when the cap C is detached from the pen tip and released, the string-like object 1 'contracts and the holding short cylinder 4 of the cap C is moved to the base end side of the writing instrument B, that is, the mounting short cylinder 3 side And is automatically separated upward from the pen tip side and held at a position where it does not interfere with writing.

[0033]

As described above, according to the cap for a writing instrument according to the first aspect of the present invention, one end of the string is attached to the base end of the writing instrument and the length of the string is measured in the longitudinal direction. The cap of the writing implement is attached to the middle part, and a loop for holding the cord is formed at the other end of the cord, so that the cap accidentally comes off when the writing implement is carried. However, since it is held by the string, there is no danger of dropping or losing, and in use, the cap is removed and the holding member formed on the other end of the string is used. By inserting and locking the loop for a finger or the like, the writing instrument and its cap can be in a state of being supported by the user's hand side via a cord-like material,
There is no need to find a place where the cap is temporarily placed, and the writing instrument and the cap can be used with the cap prevented from falling. Therefore, in a writing instrument using a volatile ink such as a felt pen, it is possible to solve the problem that the cap cannot be used due to loss of the cap and must be discarded.

Further, when the loop for holding the string is attached to the user's hand, the cap of the writing instrument attached to the string is pulled and held at a position separated from the pen tip of the writing instrument. Can be kept in place and will not interfere with writing. Further, even if the writing implement is accidentally released during writing, the writing implement is also held on the hand side by the string-like material, so that the writing implement can be reliably prevented from falling.

According to the second aspect of the present invention, the short tubular body for attachment to the base end of the writing instrument is connected to one end of the string-like object, and a middle portion in the length direction of the string-like object. Since the short cylinder for holding the cap of the writing implement is attached to the part, it is easy to fit the short cylinder for mounting on the base end of the writing implement and insert the cap of the writing implement on the short cylinder for holding the cap easily. Not only can the strap be attached to the writing instrument and the cap can be attached to the strap, but if the strap is cut or the short cylinder is damaged, replace it with a new cap holder. By attaching the mounting short cylinder to the base end of the writing instrument, it is possible to provide a structure capable of preventing the cap from being dropped or lost again.

In addition, if the short cylinder for holding the cap is attached to the string-like object so as to be slidable in the length direction,
When not in use, the cap can be moved to the loop side of the cord and put it over the pen tip of the writing implement, and the cord can be extended along the writing implement so that it is easy to handle Further, after use, the cap can be removed and then moved along the string to one end or the other end of the string, so that the cap does not interfere with the writing operation. It can be held in a position where it is not necessary.

Further, the string-like material may be formed from a rubber string which can elastically expand and contract in the length direction. In this case,
Not only can the string be shortened in the same manner as the string in which the cap-holding short cylinder is slidably movable, but also by extending the string and covering the writing instrument with the cap. The cap can be firmly covered with the writing instrument by the elastic pulling force of the cord-like material, so that the airtightness in the cap can be maintained and the volatilization of the ink can be reliably prevented, and at the same time, the writing instrument can be accidentally cut from the tip. The pen tip can be always kept covered when not in use, without slipping out.
