Abstract

(57) [Summary] [Purpose] To provide a non-slip device capable of recognizing the ink amount, ink color, etc. in a transparent gripping shaft. [Structure] The tubular body 1 attached to the grip portion of the transparent grip shaft 2 is made of a transparent thermoplastic elastomer. The tubular body 1 can be made of a transparent polyolefin-based synthetic resin, polypropylene resin, or polyethylene resin. The tubular body 1 forms the minimum diameter portion 3 at the intermediate portion in the length direction of the outer peripheral surface.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of an anti-slip device attached to a gripping barrel (hereinafter, these gripping barrels are referred to as a gripping shaft) such as a writing instrument barrel, a makeup brush barrel, and the like. .

[0002]

[Prior art and problems]

 As shown in FIG. 4, it has already been proposed to attach a rubber tube 1'for the purpose of preventing slippage to the grip portion of the grip shaft 2'to form a slip stopper. (For example, FIG. 1 of Japanese Utility Model Publication No. 55-11 5884 and its description, FIG. 1 of Japanese Utility Model Publication No. 61-109774 and its description, etc.)

[0003] The above-mentioned prior art has achieved some results in terms of exhibiting the anti-slip function, but both the rubber tube 1'and the grip shaft 2'are opaque, or the grip shaft 2 '. Although the rubber tube 1'is transparent, there is an inconvenience that the amount of ink in the grip shaft 2'and the ink color cannot be seen from the outside of the rubber tube 1'because the rubber tube 1'is opaque. When the amount of ink in the 'becomes small, there is a disadvantage that you have to use it while paying attention to the remaining amount of ink.

The present invention has been made by paying attention to such inconveniences and disadvantages of the prior art, and if it is attached to the grip portion of the transparent grip shaft, the ink amount, ink color, etc. in the grip shaft can be checked. The purpose is to provide a useful, non-slip device.

[0005]

[Means for solving problems]

 In order to achieve the above-mentioned object, the means made by the present invention comprises a transparent thermoplastic elastomer, a transparent polyolefin synthetic resin, a polypropylene resin, or a polyethylene resin for the tubular body attached to the grip portion of the transparent grip shaft. That is, a minimum diameter portion is formed at a longitudinally intermediate portion on the outer peripheral surface of the tubular body.

[0006]

[Action]

 Since the tube is transparent, if it is attached to the transparent grip shaft, it is possible to see through the ink amount and ink color in the grip shaft from the outside of the tube. Then, if the minimum diameter portion of the tubular body in the longitudinal direction is gripped, it becomes difficult for the finger to slide in the longitudinal direction of the tubular body.

[0007]

【Example】

 This will be described with reference to FIGS. The tubular body 1 is made of a thermoplastic elastomer, more specifically, a polyolefin-based one of the elastomers, that is, a transparent polyolefin-based synthetic resin, and more specifically, a transparent (semi-transparent) material such as polypropylene or polyethylene in the synthetic resin. It is made of synthetic resin (including transparent). The above-mentioned polyolefin-based thermoplastic elastomer constituting the tubular body 1 is improved from a conventional resinous elastomer like an elastic rubber, and exhibits elasticity and a non-slip function.

The tubular body 1 has a minimum diameter portion 3 (constriction portion) at an intermediate portion in the lengthwise direction on the outer peripheral surface, and the diameter gradually increases from the minimum diameter portion to both ends in the lengthwise direction. Then, the outer diameters of the both ends are set to the maximum equal diameter (r ₁ = r _{2 in the} figure). The minimum diameter portion 3 (minimum diameter r _{3 in the} drawing) is configured at a portion where the tubular body 1 attached to the gripping shaft 2 is most commonly gripped, and when the minimum diameter portion 3 is gripped, The fingers should be designed so that they do not slip easily toward both ends.

However, there is no necessity that the outer diameters at both ends of the tubular body 1 in the longitudinal direction must be set to r ₁ = r ₂ , and the relationship of r ₁ > r ₃ and r ₂ > r ₃ is satisfied. As long as the outer diameter satisfies the above condition, it does not matter whether the outer diameter is r ₁ > r ₂ or r ₂ > r ₁ . The tubular body 1 has an equal inner diameter over its entire length, and is fitted into the mounting groove 4 of the transparent grip shaft 2 to be mounted.

The transparent gripping shaft 2 has an annular mounting groove 4 for fitting the tubular body 1 on the outer peripheral surface of the most commonly gripped portion, so that the tubular body 1 is not displaced. It is configured to be installed. The material of the transparent gripping shaft 2 may be a known transparent synthetic resin such as a hard vinyl chloride resin or a polystyrene resin, or a transparent synthetic resin other than the resin.

When the tube body 1 is configured as described above, it becomes transparent, so that it becomes possible to check the ink amount and the ink color in the transparent grip shaft 2, and the elasticity and the anti-slip function are provided. By exerting the effect, if it is attached to the transparent gripping shaft 2, it becomes possible to grip the finger with less concern about slipping and fatigue of the finger.

[0012]

【effect】

 Since the present invention is constructed as described above, the tube body is transparent. Therefore, if the tube is attached to the transparent gripping shaft, the amount of ink in the gripping shaft, the ink color, and the like can be seen through the pipe, and especially the ink inside the transparent gripping shaft can be seen. It is convenient to use while easily checking the remaining amount.

Further, since the tubular body has the minimum diameter portion at the longitudinally intermediate portion on the outer peripheral surface, if the minimum diameter portion is gripped, it becomes difficult for the finger to slip in the longitudinal direction of the tubular body. Therefore, if the tubular body is attached to the transparent gripping shaft, the gripping shaft can be gripped with less fear of slipping, and the gripping shaft can be made easy to use.
