Description

Adhesive cleaner

The present invention relates to an adhesive cleaner that captures dust adhering to a surface to be cleaned by the adhesive surface by rolling an adhesive tape roll wound with the adhesive surface facing the front side on the surface to be cleaned. For example, the present invention relates to a small and portable adhesive cleaner.

There is a portable adhesive cleaner that uses adhesive tape as one of the cleaners that removes dust adhering to clothes. For example, Patent Document 1 discloses a cleaning tool body having a support shaft that rotatably holds an adhesive tape roll wound so that the adhesive surface of the adhesive tape faces the front side, and an adhesive tape roll with respect to the cleaning tool body. The portable adhesive type cleaning tool which has a protective case attached so that the outer peripheral surface of this may be covered is described.

In this adhesive cleaning tool, a grip portion that is gripped by a hand during use is foldably connected to one end side of the support shaft. The grip portion also serves as a locking means for the protective case when folded. According to this, it can be used by removing the protective case after expanding the folded grip so as to be coaxial with the support shaft. The user can catch dust on the adhesive surface by holding the grip by hand and rolling the surface of the adhesive tape roll on the clothes.

However, the following problems remain in the adhesive cleaner described in Patent Document 1. That is, since the grip is foldable with respect to the support shaft, the outer diameter in the folded state is large. Therefore, since it becomes large and bulky as a whole, it is inconvenient to carry in a small bag.

Also, since the grip part is foldable and also serves as a locking means, the grip must first be unfolded before use, and cannot be used with a single touch.

3A and 3B, the stopper 4 includes an end plate 41 that supports one end side of the adhesive tape roll R, and a locking shaft 42 that protrudes from the center of the end plate 41. ing. The end plate 41 has a disk shape larger than the maximum outer diameter of the adhesive tape roll R, and the bottom plate (the bottom surface in FIG. 3A) is used for alignment provided at the bottom of the protective case 3. A concave portion 43 that engages with the convex portion 361 is provided.

The locking shaft 42 is a cylindrical shaft erected vertically from the center of the upper surface of the end plate 41 (upper surface in FIG. 3A), and has an outer diameter that can be inserted along the inner peripheral surface of the support shaft 21. Have. A locking groove 44 for guiding the hook claw 212 is provided on the outer peripheral surface of the locking shaft 42.

The locking groove 44 is formed substantially horizontally along the circumferential direction of the locking shaft 42 from one end of the introducing portion 44a from the upper end of the locking shaft 42 and extending vertically along the axial direction. It is formed in an L shape having a stopper 44b. The locking portion 44b is formed such that the opening width (length in the axial direction) is small on the inlet side and increases toward the back.

According to this, when the locking shaft 42 of the stopper 4 is inserted into the inner diameter of the support shaft 21, the hook claw 212 is inserted so as to enter the introduction portion 44 a of the locking groove 44, and in this example, about 90 clockwise. After the rotation, the stopper 42 is slightly pulled out in the axial direction, so that the hook claw 212 enters the locking portion 44b and is locked, and the stopper 4 is attached to the tip of the support shaft 21.

Referring again to FIG. 2, the grip portion 22 is formed integrally with the upper end of the support shaft 21, and is easily gripped by hand. It is formed in a cylindrical shape with a gradually decreasing diameter. The lid plate 221 is fitted into the upper end of the grip portion 22, but the lid plate 221 may be integrated.

The lower end (lower end in FIG. 2) side of the grip portion 22 is provided with a locking surface 23 for locking the cleaning tool body 2 and the protection case 3 when the cleaning tool body 2 is inserted into the protection case 3. ing. The locking surface 23 is formed so as to be smaller than the outer diameter of the grip portion 22.

The locking surface 23 is also formed so that the outer diameter gradually decreases from the upper end side (the connection side with the grip portion 22) toward the lower end side (the connection side with the support shaft 21). Is formed slightly smaller than the opening diameter of the protective case 3.

The outer peripheral surface of the locking surface 23 is provided with a locking convex portion 231 that enters into a concave groove 35 provided on the protective case 3 side. In this example, the locking projections 231 are formed of protruding ribs protruding outward from the outer peripheral surface of the locking surface, and in this example, three are provided at intervals of 120 °.

The number and shape of the locking projections 231 may be arbitrarily changed according to the specifications. Further, an annular rib may be provided in place of the locking convex portion 231 as long as it has a shape that enters and engages with the concave groove 35.

Next, referring to FIG. 4, the protective case 3 has a hollow cylindrical shape having an opening 31 at the top, and the outer diameter is from the upper end (the upper end in FIG. 4A) to the lower end (FIG. 4A). Then, it is formed into a conical cylinder shape that gradually increases toward the lower end.

The inner peripheral surface 32 of the protective case 3 is formed so that the inner diameter thereof gradually increases from the upper end to the lower end, like the outer diameter. In this example, an insertion surface 34 that receives the above-described locking surface 23 is formed for a predetermined length from the opening 31 of the protective case 3.

The insertion surface 34 has an axial length substantially the same as the axial length of the locking surface 23, and the inner diameter is substantially the same as the outer diameter of the locking surface 23. The insertion surface 34 is provided with a concave groove 35 in which the above-described locking projection 231 is locked. In this example, the concave groove 35 is an annular groove that is recessed by one step along the inner diameter of the insertion surface 34. The position and shape of the concave groove 35 may be arbitrarily selected according to the specification.

The inner peripheral surface 32 is provided with a rib 33 for preventing the adhesive surface from sticking to the inner peripheral surface 32 when the adhesive tape roll R is inserted in an inclined state with respect to the axis. ing.

The ribs 33 are formed along the axial direction from the lower end to the bottom of the insertion surface 34 on the inner peripheral surface of the protective case 3, and in this example, 12 ribs are provided radially at predetermined intervals. The shape and number of the ribs 33 are arbitrary.

Referring also to FIG. 5, a bottom cover 36 is attached to the bottom of the protective case 3. The bottom lid 36 is a lid that can be fitted along the bottom opening of the protective case 3, and is inserted along the inner peripheral surface 32 of the protective case 3. The shape and mounting manner of the bottom lid 36 may be arbitrary.

A convex portion 361 for receiving a concave portion 43 provided on the bottom portion of the stopper 4 of the cleaning tool main body 2 is provided on the upper surface of the bottom lid 36 (the upper surface in FIG. 5B). In this example, the convex portion 361 is formed by arranging two convex ribs formed in a semicircular shape in a cross shape, and when the convex portion 361 enters the concave portion 43, the support shaft 21 and the protective case are arranged. The center axis lines of 3 coincide with each other.

Next, an example of a procedure for using the adhesive cleaner 1 will be described with reference to FIGS. 6 to 8 together. First, when attaching the adhesive tape roll R to the cleaning tool body 2, the tip of the support shaft 21 of the cleaning tool body 2 is inserted until it abuts along the inner diameter of the adhesive tape roll R.

Next, the stopper 4 is attached to the tip of the support shaft 21. Thereby, the adhesive tape roll R is rotatably held on the support shaft 21. When using the cleaning tool main body 2, the protective seal provided on the outer periphery of the adhesive tape roll R is peeled off, and then the adhesive surface exposed on the surface (both not shown) is rolled on the clothing, etc. Adhering dust can be captured by the adhesive surface.

After use, as shown in FIG. 7, the support shaft 21 is inserted from the tip (stopper 4 side) into the opening 31 of the protective case 3. In the present invention, the outer diameter of the stopper 4 is the maximum outer diameter of the adhesive tape roll R. The stopper 4 comes into contact with the periphery of the opening 31 before the adhesive surface adheres to the periphery of the opening 31 even when the cleaning tool body 2 is inserted into the opening 31 in a tilted state. Thus, the adhesive tape roll R can be prevented from touching the opening 31.

Furthermore, even if the cleaning tool body 2 is tilted when it is inserted all the way into, the rib 33 touches the outer periphery of the stopper 4 so that the adhesive surface touches the periphery of the opening 31 and becomes dirty or the adhesive surface peels off. Can be prevented.

Further, when the cleaning tool main body 2 is pushed to the bottom of the protective case 3, the concave portion 43 of the stopper 4 is guided to the convex portion 361 provided on the bottom cover 36 of the protective case 3 and the insertion surface 23 of the cleaning tool main body 2 is inserted. And the locking surface 34 of the protective case 3 are engaged with each other.

According to this, the support tape 21 is supported at two points on the distal end side (stopper 4 side) and the proximal end side (grip portion 22 side), so that the adhesive tape roll R is along the central axis of the protective case 3. Therefore, the adhesive surface can be reliably prevented from sticking to the inner peripheral surface of the protective case 3. In particular, it is possible to prevent the adhesive tape roll R from rattling in the protective case 3 while being carried around.

In this example, the protective case 3 is formed in a conical shape in conformity with the inner diameter so as to be stable when stationary. However, the protective case 3 has a cylindrical shape on the inner and outer peripheral surfaces. Alternatively, it is sufficient that at least the inner peripheral surface can accommodate the adhesive tape roll R, and the outer shape may be a square or the like.
