  Normally, the adhesive cleaner 1 is provided with a protective cover (not shown) for protecting the adhesive surface 21 of the adhesive tape roll 2 when the adhesive cleaner 1 is not used. This is an optional item, and its illustration and description are omitted.

  The pressure-sensitive adhesive tape roll 2 is formed by winding a pressure-sensitive adhesive tape having a dust-capturing pressure-sensitive adhesive surface 21 on one surface of a base material in a multiple manner along the core 22 so that the pressure-sensitive adhesive surface faces the front side. The adhesive tape roll 2 is provided with a cut (not shown) for cutting off the dirty adhesive tape almost every one circumference.

  In the present invention, the pressure-sensitive adhesive tape roll 2 only needs to be wound so that the pressure-sensitive adhesive surface faces the front side for cleaning, and the material and thickness of the pressure-sensitive adhesive, the pattern shape of the pressure-sensitive adhesive surface, or the presence or absence of cuts and the shape Etc. may be arbitrarily selected.

  In this example, the core 22 is a so-called paper tube, and the adhesive tape is wound in multiple rolls around the core 22. The core 22 may be made of a resin other than the paper tube. Further, a so-called coreless type in which only the adhesive tape is wound in a roll shape without the winding core 22 may be used.

  The cleaning tool body 3 includes a grip portion 4 that is gripped by a hand, a shaft 5 that is connected to one end of the grip portion 4 (the lower end in FIG. 1), and a shaft 5 that is coaxially rotatable to the other end side. And a support roller 6 to be connected.

  As shown in FIG. 1, the grip part 4 consists of a synthetic resin molded product, and is formed in a slightly flat rod shape so that it can be easily gripped by hand. In this embodiment, a hook hole 41 is provided on the upper end side of the grip portion 4 for suspending and storing the adhesive cleaner 1 on a hanging tool such as a hook.

  In this example, the grip portion 4 is made of a straight rod body made of a synthetic resin and having an elliptical cross section. However, the grip portion 4 may be made of metal, and the shape may be a T shape, an L shape, or the like. Further, the surface may be roughened or textured so that it can be easily held by hand, and the specific material and shape of the grip portion 4 may be arbitrarily changed according to specifications.

  As shown in FIG. 1, the shaft 5 is made of a metal rod bent or curved into a predetermined shape from one end side to the other end side. The shaft 5 includes a shaft support portion 51 that pivotally supports the support roller 6, a curved portion 52 bent from the shaft support portion 51 into a substantially U shape, and a substantially right angle from the curved portion 52 via the bent portion 53.

  Conversely, by adjusting the stem 54 to a short length, a hand such as a table or a sofa can be cleaned. In this example, the stem 54 is provided with a telescopic expansion / contraction means. However, the expansion / contraction means is not particularly limited, and may be a simple rod shape having no elasticity.

  In this embodiment, the shaft 5 is formed by bending or bending a metal rod, but may be formed by press molding or the like. The shaft 5 may be made of resin other than metal. In the present invention, the specific configuration of the shaft 5 may be arbitrary.

  Next, the support roller 6 of the first embodiment will be described with reference to FIG. The support roller 6 is made of a synthetic resin molded product, and is entirely formed in a cylindrical shape that can be inserted along the inner peripheral surface of the adhesive tape roll 2.

  The support roller 6 includes a pair of support plates 61a and 61b that are extended in parallel along the axial direction of the adhesive tape roll 2, and end plates 62a and 62b that cover end surfaces of the support plates 61a and 61b. The support plates 61a and 61b and the end plates 62a and 62b are integrally formed by injection molding.

  The support plates 61a and 61b are beam members having a T-shaped cross section extending along the axial direction of the adhesive tape roll 2, and are disposed symmetrically with the rotation axis therebetween. Reinforcing ribs 611 and 611 are provided in two portions at predetermined intervals along the axial direction in part of the support plates 61a and 61b.

  The support plates 61 a and 61 b are arranged so that the circumscribed circle in the circumferential direction is substantially the same as the inner diameter of the adhesive tape roll 2. In other words, in this example, the support plates 61 a and 61 b have a T-shaped cross section, and are arranged so that the circumscribed circle connecting the apexes of the sides is substantially the same as the inner diameter of the adhesive tape roll 2.

  In this example, the support plates 61a and 61b are both of the same shape and are formed in a T-shaped cross section. However, if the circumscribed circle is arranged to be substantially the same as the inner diameter of the adhesive tape roll 2, the number The shape may be arbitrary depending on the specification.

  The end plates 62a and 62b are made of a disc body having an outer diameter substantially the same as the inner diameter of the adhesive tape roll 2, and are attached so as to close the end portions of the support plates 61a and 61b. Of the two end plates 62a and 62b, one end plate 62a (left end in FIG. 2A) is provided with a bearing hole 621 into which the shaft support portion 51 of the shaft 5 is inserted.

  The other end plate 62b (the right end in FIG. 2A) is provided with a guide cap 63 that serves as a guide when the support roller 6 is inserted along the inner diameter of the adhesive tape roll 2. The guide cap 63 is formed in a cylindrical shape, and a tapered surface 631 is formed at the tip thereof so that the adhesive tape roll 2 can be easily inserted. In this example, the guide cap 63 is integrally formed with the end plate 62b, but may be a separate body. In the present invention, the configuration of the guide cap 63 may be arbitrary.

  A bearing portion 64 for bearing the shaft support portion 51 of the shaft 5 is provided at substantially the center in the axial direction across the support plates 61a and 61b. The bearing portion 64 is integrally formed with the support plates 61a and 61b, and a metal bearing member (not shown) is provided inside. The support roller 6 rotates about the axis of the bearing portion 64 by inserting the shaft support portion 51 coaxially along the bearing portion 64.

  An end cap 65 that supports the other end side of the adhesive tape roll 2 is provided on the end plate 62a on the shaft support end side (left end in FIG. 2) into which the shaft 5 is inserted. The end cap 65 has a cylindrical shape integrally formed with the end plate 62a, and a locking claw 651 for receiving one end (terminal side) of the adhesive tape roll 2 is provided at the end thereof. The locking claw 651 is a stopper for preventing the inserted adhesive tape roll 2 from passing through the support roller 6 and coming out to the shaft support portion 65 side.

  The end cap 65 is provided with elastic pieces 66 and 66 for locking the adhesive tape roll 2 to the support roller 6. The elastic pieces 66 and 66 are elastically deformable tongue pieces formed by two slit grooves 661 and 661 formed along the axial direction of the end cap 65. In the free end (FIG. 2A), The left end is formed so as to protrude along the axial direction of the support roller 6.

  The elastic pieces 66, 66 are formed in an arc shape because the outer periphery is inserted along the inner diameter of the adhesive tape roll 2, and the inner peripheral surface of the adhesive tape roll 2 is pressed against the outer peripheral surface of the elastic pieces 66, 66. A locking projection 662 for stopping is provided.

  The locking convex portion 662 is a convex portion having a semicircular cross-section projecting outward from the outer peripheral surface of the elastic piece 66 in the radial direction, and the top portion thereof is located outside the inner diameter of the adhesive tape roll 2. It is formed as follows.

  According to this, as shown in FIG. 3, when the adhesive tape roll 2 is inserted from the free end side (right end side in FIG. 3) of the support roller 6, the tip of the adhesive tape roll 2 is engaged with the end cap 65. It catches on the pawl 651 and stops.

  At that time, the locking projection 662 of the elastic piece 66 is pushed down in the inner diameter direction by the winding core 22, and the locking projection 662 presses the winding core 22 by the elastic restoring force. Thereby, the friction coefficient between the adhesive tape roll 2 and the support roller 6 is increased, and the adhesive tape roll 2 is prevented from falling off to the free end side.

  In removing the adhesive tape roll 2 (the core 22 when used) from the support roller 6, as shown in FIG. 4, for example, the elastic pieces 66, 66 are pinched with the thumb and index finger, and the elastic pieces are left as they are. 66 and 66 are pushed in the inner diameter direction.

  As a result, the locking projection 662 is pushed further inward than the inner diameter of the core 22, so that the locking by the locking projection 662 is released. With the lock released, the adhesive tape 2 can be extracted from the support roller 6 with one touch by pulling out the adhesive tape 2 with one hand or by turning the free end of the support roller 6 downward.

  In this example, the elastic pieces 66 and 66 are provided at two places. However, in order to fix the adhesive tape roll 2 to the support roller 6, it is sufficient that at least one place is provided. Instead of the locking projection 662, the thickness of the elastic piece 66 may be formed so as to gradually increase in the inner diameter direction of the pressure-sensitive adhesive tape roll 2 from the base end side toward the free end side.

  As one of the methods for further ensuring the coupling between the adhesive tape roll 2 and the support roller 6, as shown in FIG. 5A, an opening 221 is provided in a part of the core 22, and the opening 221 is provided. The locking convex portion 662 may be made to match.

  According to this, the retaining protrusion 662 enters the opening 221, thereby further improving the effect of preventing the adhesive tape roll 2 from coming off. In this example, the opening 221 is a through-hole, but may be a recess as long as the locking projection 662 can enter. Further, it may be an annular groove formed along the inner peripheral surface of the winding core 22.

  Further, when used for a long time, the elastic pieces 66 and 66 may fall. Therefore, as shown in FIG. 6, reinforcing ribs 663 and 663 may be provided on the inner diameter side of the elastic pieces 66 and 66 in order to prevent the elastic pieces 66 and 66 from sagging.

  According to this, since the rigidity of the elastic pieces 66, 66 is maintained by the reinforcing ribs 663, 663, it is possible to prevent sag due to creep deformation even when the elastic pieces 66, 66 are deformed over a long period of time. it can. In addition, it is preferable that the reinforcing ribs 663 and 663 are formed so that the height gradually decreases from the base end side toward the distal end side so that the reinforcing ribs 663 and 663 can be easily deformed by a finger. Such an embodiment is also included in the present invention.

  As another method for preventing the elastic pieces 66 and 66 from sagging, a spring member for always pressing the elastic pieces 66 and 66 toward the outer peripheral direction may be used. As shown in FIG. 7, the spring member 7 a is a plate spring member formed by bending a metal plate into a C shape, and is disposed along the inner peripheral surface of the end cap 65.

  According to this, the elastic pieces 66, 66 can always be pressed toward the outer peripheral direction by the elastic restoring force of the spring member 7a, and sag can be prevented. As a modification of this spring member, as shown in FIG. 8, a spring member 7b obtained by bending a metal plate into a U shape may be used.

  In this case, by disposing both end portions bent in a U-shape along the inner side of the elastic pieces 66, 66, the elastic pieces 66, 66 can always be pressed toward the outer peripheral direction, and sag is suppressed. be able to. Such an embodiment is also included in the present invention.

  As yet another aspect, as shown in FIG. 9, operation pieces 67 and 67 made of other elastic pieces may be provided so as to surround the elastic pieces 66 and 66. According to this, the elastic pieces 66 and 66 can be pushed in simultaneously by pushing the operation pieces 67 and 67 inward, and even if the rigidity of the elastic pieces 66 and 66 is increased, the elastic piece 66 can be easily obtained. 66 can be deformed.
