DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a marking chalk holder suitable for being carried by a police officer.

[0002]

2. Description of the Related Art Police officers in charge of traffic violations usually carry marking chalks, which are used to mark vehicles that violate parking (for example, the date and time when a parking violation was found). Is done. The conventional marking choke is attached to the tip of a relatively long cylindrical holder, and is of a type installed as necessary equipment in the cabin of a police car.

[0003] A conventional marking choke holder is of a type that is inserted by being inserted into the tip of a relatively long cylindrical holder. That is, it is not a size that can be stored compactly in a pocket, so it is inconvenient to carry it at all times, so that it is taken out of the passenger compartment every time it is used, which is not convenient.

[0004] As a holder for a compact marking choke, Japanese Utility Model Laid-Open No. 57-19085 discloses a holder having a cylindrical body having a plurality of circumferentially spaced slits at its tip. The tubular body defines a slit along its length, and the slider is connected to the marking choke by a ring. Therefore, the marking chalk can be extended or retracted from the cylindrical main body by sliding the slider. The slit at the tip of the cylindrical body gives the marking chalk a radially inward elastic force so as to restrict the marking chalk to a desired position.

[0005]

Problems to be Solved by the Invention
In the technique disclosed in Japanese Patent Application Laid-Open No. 5-205, a slit which is circumferentially separated is formed at the tip of a cylindrical main body, and a marking chalk can be held at an arbitrary position by a radially inward elastic force obtained thereby. Since the holding of the marking chalk depends only on the elastic force of the cylindrical body, there is a problem that the harmony between the elastic force and the holding force is delicate and the operability is not always good. In other words, if the elasticity of the slit part is insufficient, the marking chalk slips with a slight force, and the workability at the time of marking deteriorates. When the marking chalk is consumed, the resistance when the unused portion of the marking chalk is extended is increased.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems of the prior art, and has been described in detail with reference to the accompanying drawings. It is an object of the present invention to provide a choke holder that can also hold.

[0007]

According to the first aspect of the present invention, a cylindrical main body, a marking choke inserted into the cylindrical main body, and a slidable insertion into a slit formed in the cylindrical main body. A slider to be connected, the slider is connected to the marking choke, a connecting means for moving the marking choke in the cylindrical body by the movement of the slider, and a click stop means installed between the opposing surfaces of the slit and the slider, There is provided a marking choke holder, wherein the click stop means click-stops the slider at predetermined intervals when the slider slides along the slit.

[0008] The function and effect of the first aspect of the present invention will be described. The marking choke is extended from the cylindrical main body or accommodated in the cylindrical main body by moving the slider. The click stop means click-stops the slider every time the slider is moved, and the slider and the marking choke connected thereto are restrained at that position.
Therefore, the required mark can be applied to the target such as the road surface by the marking choke, and a force in the direction of releasing the clip stop mechanism is applied when marking with the marking choke, but the click stop mechanism is used for such a normal marking. Depending on the pen pressure, the marking chalk is maintained in a restrained state, so that there is no hindrance to the marking operation. When the marking chalk is housed in the tubular main body, the clip stop mechanism can be overcome by moving the slider against the resistance force of the click stop mechanism, and the marking chalk can be housed in the main body. In the present invention, the marking chalk can be extended and stored freely by the slider, and no problem occurs in storing the marking chalk in the pocket. By providing the clip stop mechanism, the marking chalk can be moved to a desired position with a force larger than the pen pressure. Therefore, the choke does not move at the time of marking, and the feeling of use is not impaired.

According to the second aspect of the present invention, the first aspect is provided.
In the invention described in the above, the click stop means comprises an elastic strip having a recess formed at intervals along the slit, and an engaging member provided on the slider so as to extend toward the elastic strip, When the slider slides along the edge, the tip of the engaging member is engaged with one recess of the elastic strip, and sliding of the slider along the slit makes it possible to overcome this recess against the elastic force of the elastic strip. A marking chalk holder is provided.

The operation and effect of the second aspect of the present invention will be described. When the slider is slid, the engaging member at the tip of the slider is engaged (click-stopped) with each recess of the elastic strip formed in the slit. When the slider is moved by a force that overcomes the elastic force of the strip, the engagement member can get over this depression and move to the next depression. In this manner, the engagement of the engaging member provided at the tip of the slider with the recessed portion of the elastic strip allows the slider, in other words, the marking choke to be reliably restrained at that position.

According to the invention described in claim 3, according to claim 1 of the present invention,
In the invention described in (1), a choke holder is provided, in which the marking choke holder has a writing instrument shape as a whole, and a clip portion extends from the slider.

According to the third aspect of the present invention, the marking chalk holder is formed in a writing instrument shape, and a clip portion is extended from a slider so that the marking chalk is housed in a cylindrical container. It can be easily stored in a portable device such as a police officer in charge of a traffic violation.

[0013] According to the invention described in claim 4, according to claim 1 of the present invention.
In the invention described in (1), a connecting means for connecting the slider and the marking choke is a needle-shaped member, and a marking chalk holder is provided.

The operation and effect of the fourth aspect of the present invention will be described. The connection between the slider and the marking choke can be easily performed simply by pushing the needle-shaped member into the marking choke and inserting it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS With reference to FIGS. 1, 2 and 3, the marking choke holder of the present invention comprises a cylindrical body 10 made of plastic. Both ends of the cylindrical main body 10 are open, one end 10A is inclined, a marking chalk is protruded and retracted, and a cap 11 is screwed to the other end 10B. The marking chalk 12 is chalk, crayon, or the like, and is inserted into the internal cavity of the tubular main body 10.

A slit 14 penetrating in the radial direction in the longitudinal direction of the cylindrical body is formed. The slit 14 is a slit portion 14-1 penetrating vertically and a side surface opened laterally to the slit portion 14-1. Opening 14-2. The slider 16 is disposed so as to be slidable in the longitudinal direction along the slit 14. The slider 16 includes an operation unit 16-1 and an operation unit 16-1.
A guide portion 16-2 projecting vertically downward from the guide portion, and a retaining portion 16-3 extending horizontally on both sides of the guide portion 16-2. The guide portion 16-2 of the slider 16 is fitted into the slit portion 14-1, so that the slider 16 can slide in the longitudinal direction (arrows f1 and f2). The retaining portion 16-3 of the slider 16 has a slit 1
The slider 16 extends to the side opening 14-2 of the slider 4, thereby holding the slider 16 so as not to fall out of the slit 14.

According to the present invention, there is provided the click stop mechanism for restraining and stopping the slider at the spaced position when the slider slides in the longitudinal direction. Describing the click stop mechanism, an elastic strip 18 is accommodated in one side opening 14-2 (left side in FIG. 2) of the slit 14, and is fixed by an appropriate means. One of the sliders 16 facing the elastic strip 18 (left side in FIG. 2)
The stopper ball 20 is accommodated in the retaining portion 16-3 so that it can rotate freely as much as possible. The elastic strip 18 is formed of a metal elastic strip, and has a plurality of depressions 18-1 having a substantially semicircular cross section at intervals in the longitudinal direction, as shown in FIG. . The elastic strip has an elastic connecting portion 18-2 between the adjacent depressions 18-1. The stopper ball 20 holds the slider 16 at that position by engaging with one recess 18-1 when the slider 16 slides along the slit 14. When an axial force is applied to the slider 16 in a state where the stopper ball 20 is engaged with one of the recesses 18-1, the ball 20 is released from the recess 18-1 and the ball 20 is resiliently connected to the elastic connecting portion 18. -2 is pressed outward, moves while elastically deforming, and is engaged with the next recess 18-1. With such a click stop mechanism, the slider 16 is elastically held at predetermined intervals while sliding in the longitudinal direction.

In FIG. 1, a fastening needle 24 is implanted on the lower surface of the slider 16, and the fastening needle 24 is pierced by the marking choke 12 so that the slider 16 is connected to the marking choke. 16

The slider 16 has a clip 17 at the tip. The holder for marking choke of the present invention is in the form of a writing instrument as a whole. Police can always be carried with them, and responding to breaching vehicles can be done very quickly. The clip 17 may be of a vertical rotation type if necessary.

When the holder for marking choke of the present invention is used, by pressing the slider 16 with a finger, the stopper ball 20 escapes from one of the recesses 18-1 containing the slider ball, and the slider 16 is elastically moved by the stopper ball 20. Sliding while elastically deforming the dynamic connection portion 18-2 (arrow f1 or f
(2 directions), and is engaged with the next recess 18-1 and held at this position. By continuing such a click stop type movement, the tip of the marking choke 12 can be made to protrude from the tip of the cylindrical main body 10 by a required amount as shown by the broken line in FIG. The force (= elastic force of the elastic strip 18) when the stopper ball 20 is released from the state in which the recess 18-1 is accommodated is a desired writing pressure applied to the marking chalk in the state in which the stopper ball 20 accommodates the recess 18-1. When the marking chalk 12 is moved backward or backward by sliding the slider 16 back and forth, the stopper ball 20 is not moved.
A large force is not applied to cause the marking chalk 12 to escape from the depression 18-1, that is, the operability when the marking choke 12 is extended and retracted is not significantly impaired.
