Description

  The present invention relates to a holding tool that moves a roller along an inclined surface and can hold an object to be clamped by a pinching action that occurs between the rollers.

A rolling element such as a roller or a ball is provided so as to roll along an inclined surface provided in the main body, and the object to be clamped is held by inserting the object to be clamped between the rolling elements. There is a known clamping tool (see, for example, Patent Document 1). This type of clamping device can be held in the case of a relatively light object to be sandwiched, such as paper or sheet-like material. If the object to be clamped is lost and the object to be clamped falls off, or the load on the object to be clamped is heavy or the surface of the material is slippery, it cannot be securely held, and the object may slip easily. It was. In particular, shampoo packs, rinse packs, detergent packs, and other pouches for refills are made of resin film and have weight, so even if you try to fold the bottom of the pouch and hang it upside down, it will fall. Easy to hold and difficult to hold.

  The problem to be solved by the present invention is that, in the holding device using rolling elements such as rollers and balls as described above, it is possible to securely hold a material to be sandwiched that is heavy and slippery like a pouch such as a refill shampoo liquid pack. It is an object of the present invention to provide a clamping device that is not likely to fall off even when shaken, and that can be easily removed when removed.

  According to the present invention, a main body having an insertion port and having an inclined surface formed on the inner surface thereof, and being accommodated in the main body so as to be able to make rolling contact with the inclined surface facing the insertion port, is guided by the inclined surface and inserted. It comprises a roller having a locking surface so as to clamp the object to be clamped when it moves inward of the mouth, and the roller is composed of a pair of rollers facing each other in the axial direction, There is provided a clamping tool provided with a slide switch for moving one of the roller groups inward, and the above-mentioned problems are solved.

  Further, according to the present invention, a protrusion and a groove extending in the circumferential direction of the roller are formed on the locking surface of the roller group of the clamping tool, and the roller group is the above of one roller group of the opposing roller group. The said clamping tool combined with the state which the protrusion of the other roller group enters in a groove | channel is provided, and the said subject is solved.

  The present invention is configured as described above, and has a main body having an insertion port and an inclined surface formed on the inner surface thereof, and is accommodated in the main body so as to face the insertion port so as to be able to make rolling contact with the inclined surface. Provided with a roller having a locking surface so as to clamp the object to be clamped when guided and moved inward of the insertion port, and a plurality of the rollers are arranged in the axial direction and configured by a pair of rollers facing each other Therefore, even if the object to be sandwiched inserted between the roller groups from the insertion port is swung left and right, the plurality of rollers constituting the roller group move individually while sandwiching the object to be sandwiched to disperse the sandwiching action. Therefore, if the roller group is combined so that the protrusion formed on the peripheral surface of the roller enters the groove of the opposing roller without the disappearance of the sandwiching action, the sandwiching action is even stronger. Refill shampoo solution Tsu be those prone heavy sliding as in the pouch click or the like can be reliably held. In addition, since the slide switch is provided so as to move either one of the roller groups pressed in the inlet direction of the insertion port by the spring, if the slide switch is operated, the holding action may be lost. It is possible to take out the object to be sandwiched easily.

1 to 6 show an embodiment of the present invention, in which a main body 1 has an inclined surface 2 provided in an opposed state inside, and an inlet 4 that opens slightly downward in the figure. An insertion port 3 whose side surface opens in a slit shape is formed, and the inclined surface 2 is inclined so that the facing interval on the inlet 4 side located below the inserting port is narrow and the facing interval on the inward side is wide. ing. In addition, the inlet 4 of the insertion port is formed so that the central portion is slightly wider when viewed from the bottom (see FIG. 6), so that the object 5 to be sandwiched such as a pouch can be easily inserted. A retaining hole 6 is formed above the main body 1, and a cover 8 is provided on one of the side surfaces so as to cover the inner space 7. The void 7 is provided with a roller 9 facing the insertion port 3 and capable of rolling contact with the inclined surface 2 and being guided by the inclined surface 2 to move inward of the insertion port. A locking surface is formed on the outer surface so as to sandwich the object 5 to be sandwiched. In the embodiment shown in the figure, the inclined surface 2 is formed in a flat shape, but it may be formed in a curved shape, or a rotation blocking member such as an uneven line is formed on the surface so that the object to be clamped drops off. The rotation of the roller may be limited.

  As shown in FIG. 7 (A), the roller is composed of a pair of roller groups 10, 11 in which a plurality of rollers 9a, 9b and 9c, 9d are arranged in the axial direction in the axial direction. The roller groups 10 and 11 face each other. In addition, a protrusion 12 and a groove 13 extending in the circumferential direction are formed on the locking surface of the roller 9. In the embodiment shown in the figure, the protrusion 12 has a substantially mountain-shaped unevenness, but the cross-section is An inclined mountain-shaped protrusion that inclines in one direction like a check wheel may be provided, or a pin-like locking member may be formed on the protrusion. As shown in FIG. 7B, the roller groups 10 and 11 in which the rollers are arranged side by side are combined in a state in which the protrusion 12 enters the groove 13 when facing each other in the opposite state. Stored.

  The roller 9 is made of brass, but can also be made of stainless steel or other suitable metal material, or made of ceramics, hard plastic material, etc., and has a non-slip action on the surface of soft plastic material or the like. A surface layer having an integral anti-slip function may be formed by coating with a material or by multicolor molding or insert molding.

  A spring 14 that presses the roller groups 10 and 11 in the direction of the inlet 4 of the insertion port 3 is provided in the main body 1. As the spring, an appropriate spring can be used. However, in the embodiment shown in FIG. 3, a coil spring in which a spring material is wound and leg pieces 16 are protruded in a C shape at both ends of the wound portion 15. Is used. Then, a receiving piece 17 having a substantially U-shaped section having a length in contact with the rollers is formed along the upper surfaces of the plurality of rollers 9a, 9b and 9c, 9d constituting the roller group 10, 11. Each of the rollers is pressed through 17. Although the main body can be used in any manner by using the spring, the spring can be omitted if the main body is used in a vertical state. In the figure, the spring 14 is held in place by pressing the wound portion 15 with a spring presser 27 formed on the inner surface of the cover 8.

  The main body 1 is provided with a slide switch 18 for moving one of the roller groups 10 and 11 inward. The slide switch can be formed in an appropriate structure, but in the embodiment shown in the figure, it is formed in a substantially U-shaped cross section, and the side plates 19 and 20 on both sides are formed on the inner surface of the opening 21 provided in the lower part of the main body. It is incorporated in the main body 1 so that it can move up and down along. A push-up plate 22 having an inclined upper surface is formed on the upper side plate 19, and the push-up plate 22 faces the lower surface of the roller group 10. A part of the outer side plate 20 is exposed from an arc-shaped recess 23 formed on the front surface of the main body 1 so that it can be easily operated.

  Thus, in order to use the above-mentioned clamping tool, the main body may be attached to a wall such as a bathroom or a washroom, a board such as a paper clip, or any other appropriate place. For example, when hooking the retaining hole 6 on the hook member 24 provided on the wall surface as shown in FIG. 1 or using in a bathroom, for example, the suction cup 25 is fixed to the wall as shown in FIG. A hook 26 is hooked on the hook hole 6 of the main body 1, and a pouch 5 such as a refill shampoo liquid pack is turned upside down so that the bottom of the pouch is folded flat and inserted through the inlet 4 of the insertion port 3. The pouch can be securely held by the locking surfaces between the groups 10 and 11, and the pouch spout (not shown) can be suspended downward. When the required amount of shampoo liquid is taken out and used, even if the pouch is greatly shaken, the roller groups 10 and 11 constituted by the plurality of rollers 9a, 9b and 9c, 9d as described above are individually nipping. Therefore, the pinching action does not disappear as a whole and the pouch does not fall. Further, this clamping action is further ensured by the protrusion 12 and the groove 13 formed on the locking surface.

  When the contents become empty as a result of the use as described above, when the slide switch 18 is pushed in, one of the roller groups 10 is moved inward by the push-up plate 22 of the slide switch, and the clamping action is extinguished. The pouch that has been emptied can be taken out.

  As a usage mode, the above-described embodiment has been described with respect to a holding tool when a pouch such as a shampoo liquid pack is hung upside down. However, it is apparent that the holding tool of the present invention can hold other various types.
