Description

  The present invention includes various industrial products such as bedding, rugs, tatami mats, flooring, etc. in general households, shadow mask plates, light guide plates, prism sheets, polarizing plates (in the specification and claims of this application, The present invention relates to a rolling adhesive tape cleaner for removing dust, hair, lint, hair loss of pet animals, and other various foreign substances adhering to the surface.

  This type of rolling adhesive tape cleaner comprises, for example, a paper core tube and a roll-like adhesive tape wound about 90 times around, as described in JP-A-9-192070. The exposed adhesive surface of the adhesive tape is rolled onto the surface of the object to be cleaned by a handle operation, and various fine foreign matters are removed from the surface.

When a large amount of foreign matter adheres to and accumulates on the adhesive surface of the adhesive tape and the adhesive strength declines, the adhesive tape is peeled off one turn at a time along the cut line, and the exposed fresh adhesive surface. Is supposed to be used.
JP-A-9-192070

  However, when the exposed adhesive surface of the above-mentioned adhesive tape is fresh, it adheres too strongly to the surface of the object to be cleaned, so its large resistance not only makes the rolling operation light and smooth, Speaking of the adhesive strength to remove various foreign substances, it will quickly decline, and the adhesive tape must be frequently peeled off.

  In other words, the exposed fresh adhesive surface is used up at an early stage, and the adhesive force of the adhesive tape cannot be maintained on average for a long time. The convenience is inferior.

  The present invention aims to drastically solve such problems, and as a configuration for achieving the object, in claim 1, a retainer for a stretchable coil provided with a self-shrink restoring force against stretching is provided as an adhesive tape. And detachably fitted to the winding core tube or the support cap of the core tube from the side,

  By extending the free cutting tip of the coil whose base end is cut and held by the retainer, and winding it around the exposed adhesive surface of the adhesive tape in a rough spiral state at an appropriate interval pitch, The adhesive surface of the adhesive tape is narrowly restricted.

  Further, the second aspect of the present invention is characterized in that nylon, polyester, or other synthetic fiber monofilament having a constant thickness is adopted as the stretchable coil of the first aspect.

Further, in claim 3, the retainer for the stretchable coil according to claim 1 is bent in a substantially C shape from a stainless steel plate or other spring metal plate, and the both ends of the arc plate surface are separated substantially symmetrically. Bending inwardly as a letter-shaped tongue piece,
The coil separation base end portion is inserted and locked into a plurality of coil insertion holes that are distributed in at least three locations of the bending halfway portion of any one of the tongue pieces and two locations of the arc plate surface,

  Using the substantially parallel bent tips of the tongue piece as a pair of grips, the retainer's arc plate surface is bonded to the core tube of the adhesive tape or the support cap of the core tube by the expanding and restoring force obtained by contracting and deforming the diameter of the retainer It is characterized in that it is determined to be fitted in a crimped state.

  According to the above configuration of the first aspect, since the separation base end portion of the elastic coil is attached to and integrated with the wound core tube of the adhesive tape or the support cap of the core tube through the retainer, the adhesive tape cleaner As a user of the above, the free cutting tip of the coil is stretched from the retainer, wound around the exposed adhesive surface of the adhesive tape in a rough spiral state at an appropriate interval pitch, and various kinds of cleaning such as bedding and rugs If it rolls to a target object, the contact area of the said adhesive surface with respect to the surface of the cleaning target object will be narrowly limited by a coil, and the problem of the prior art mentioned at the beginning can be solved completely.

  In addition, since the coil is provided with a self-shrinking restoring force for the stretching (crimping process), when the winding state of the adhesive surface of the adhesive tape is released, the coil is pulled back to the retainer by itself. As a result of retreating from the pressure-sensitive adhesive surface, the pressure-sensitive adhesive surface of the pressure-sensitive adhesive tape whose adhesive strength has declined can be very easily peeled off by one turn, which is extremely convenient.

  In particular, if the above configuration of claim 2 is adopted, the elastic coil can be easily brazed (shape memory) and self-shrinking restoring force can be easily applied to improve durability and safety. There is an effect that can be done.

  Further, if the above configuration of claim 3 is adopted, since the retainer of the stretchable coil has a spring property capable of expanding and contracting, the diameter of the wound core tube in the adhesive tape and the diameter of the support cap are changed in size. Even if it exists, it can always be fitted or removed in a one-touch manner, and in addition, in order to form an overall substantially C-shape, the support shaft of the rolling operation handle that pivotally mounts the support cap freely. However, even if it is led out horizontally from the support cap, it is possible to fit and use the retainer of the stretchable coil without hindrance thereto, which is excellent in versatility and convenience.

  Hereinafter, specific configurations of the present invention will be described in detail with reference to the drawings. FIGS. 1 to 7 show a basic embodiment of the rolling adhesive tape cleaner, and (10) is a constant width (W1) (for example, about 16cm) paper or plastic film as a base material, adhesive tape with adhesive and release agent applied to both sides of the base material, and a hard paper or plastic wrapping core tube (11) The adhesive surface (10F) forms a roll body of a constant thickness wound in an exposed state.

  In such an adhesive tape (10), the cut line (12) for peeling is processed on the entire width or only on both right and left ends, or a guide arrow (not shown) indicating the rolling direction in use, etc. May be given.

  (H) is a rolling operation handle of the above-mentioned roll-shaped adhesive tape (10), which is bent as shown in the figure from a relatively short metal rod, and its vertical upper end is a plastic grip. The cover (13) can be gripped here, while the core pipe support roller (15) of the adhesive tape (10) is freely fitted on the horizontal support shaft (14) at the remaining lower end. Attached pivotally. (16) is a retaining washer for the core tube support roller (15), and (L) is a fixed length of the support shaft (14).

  Furthermore, the core tube support roller (15) is a plastic product having a certain length and thickness substantially corresponding to the core tube (11) of the adhesive tape (10), but only the right and left ends are particularly the core. The circular support caps (17L) and (17R) that fit into the pipe (11) have a U-shaped cross section that opens outward. (D1) is the diameter of the two support caps (17L) and (17R).

  In the case of the basic embodiment, the rolling operation handle (H) is a so-called cantilever type of the core tube support roller (15), and is one end side of the core tube support roller (15) derived from the support shaft (14) (see FIG. 5) is modeled as a relatively shallow U-shaped support cap (17L). (18) is a large-diameter circular core tube retaining flange that projects from the opening edge of the support cap (17L).

  And the free other end side (right side of FIG. 5) which does not interfere with the said spindle (14) in a core pipe support roller (15) is shape | molded as a comparatively deep cross-section U-shaped support cap (17R). Here, a pair of elastic pieces (20) facing each other are branched by a notch in the aperture shrinking groove (19). (21) is a large-diameter arc-shaped core tube retaining flange protruding from the opening edge of each elastic piece (20).

  Therefore, the core tube of the adhesive tape (10) from the lateral direction to the core tube support roller (15) by pressing the pair of opposing elastic pieces (20) and contracting and deforming the diameter of the support cap (17R). (11) can be inserted and retracted so that it can be freely inserted and removed, and the roll-shaped adhesive tape (10) can be replaced with a spare product.

  However, as shown in the first modified embodiment of FIG. 8 corresponding to FIG. 5, the core tube support roller (15) having a certain length is omitted, and its independent plastic support caps (22L) (22R) are omitted. The pair of left and right are inserted and fitted to the core tube (11) of the roll-shaped adhesive tape (10) so as to be freely inserted and removed, while projecting integrally outward from the center of each support cap (22L) (22R). The horizontal spindle (23L) (23R) is also inserted into and removed from the bearing holes (25L) (25R) formed corresponding to the pair of left and right clamping pieces (24L) (24R) in the plastic rolling operation handle (H). By freely inserting, the core tube (11) of the adhesive tape (10) may be pivotally attached to the rolling operation handle (H) as a so-called dual-support type.

  (26) is wound around the pressure-sensitive adhesive surface (10F) of the roll-shaped pressure-sensitive adhesive tape (10) so that the pressure-sensitive adhesive surface (10F) is appropriately narrowly partitioned and restricted (for example, about 70 to 100 cm). An elastic coil, which is braided from a monofilament of synthetic fiber such as nylon or polyester (preferably polyethylene terephthalate having a melting point of about 260 ° C.) having a constant thickness (for example, about 0.5 to 0.9 mm) spirally ( In addition to being processed (shape memory), self-shrinking restoring force against stretching is also given by controlling the yarn forming conditions. From the rough spiral state that is artificially stretched, the contraction and restoration are carried out by itself from the spiral state that is orderly and closely adhered.

  And the separation base end part of such an elastic coil (26) is the state hold | maintained at the following retainer (R), and the support cap (17L) which makes the right-and-left both ends of the said core pipe support roller (15) ( 17R) and a pair of left and right support caps (22L) and (22R) that are independent and detachable, and the free separating tip of the elastic coil (26) is also attached by the user of the adhesive tape cleaner. The adhesive surface (10F) of the adhesive tape (10) is wound in a rough spiral state with a desired interval pitch (P).

  Furthermore, the retainer (R) of the stretchable coil (26) is a stainless steel plate having a constant width (W2) (for example, about 6 to 10 mm) or other metal plate having a spring property as shown in FIGS. Are bent in a substantially C shape, and a pair of tongue pieces (28L) (28R) are formed in a continuous inward direction, with the arcuate plate surface (27) being cut off and having both ends separated symmetrically. It is bent.

  (29), (30), and (31) are a part of the tongue piece (28R) of one of them (the right side in FIG. 6), and two parts of the arc plate surface (27) that is biased to the same one. It is a plurality of coil insertion holes formed in a distributed manner in at least three places, and the separation base end of the elastic coil (26) is connected to the coil insertion hole (29) of the tongue piece (28R). In this state, it is possible to pass through and lock into the coil insertion holes (30) and (31) of the circular arc plate surface (27) sequentially. Thus, there is no risk of the elastic coil (26) dropping off accidentally.

  In addition, the retainer (R) of the stretchable coil (26) is a C having a diameter (D2) that is somewhat larger than the diameter (D1) of the support caps (17L) (17R) (22L) (22R) in advance. It is bent in the shape of a letter, and it is applied to the tongue pieces (28L) and (28R) as if they were a pair of handles. When the diameter (D2) of the retainer (R) is shrunk and deformed by the fingertip with the fingertip in the direction indicated by the arrow in FIG. 10, the retainer (R) is moved to the support cap (17L) (17R) ( 22L) (22R) can be fitted to the inside from the lateral direction, and when the handle is released, the arcuate plate surface (27) of the retainer (R) is expanded and restored by the expansion restoring force. (17R) 22L) (and is able to crimp integral to the inner peripheral surface of 22R).

  In that case, the diameter (D2) of the retainer (R) is preliminarily made slightly larger than the diameter (D3) of the wound core tube (11) in the roll-shaped adhesive tape (10), so that its stretchability is achieved. The retainer (R) of the coil (26) can be fitted and used in the same crimped state inside the core tube (11) as shown in the second modified embodiment of FIGS. There is no risk. That is, since the retainer (R) has a spring property that allows the diameter (D2) to expand and contract, the diameter (D1) (D3) of the support cap (17L) (17R) (22L) (22R) or the core tube (11). ) Is versatile enough to handle changes in size.

  In any case, when the adhesive tape cleaner is used, the user is fitted in a crimped state inside the support cap (17L) (17R) (22L) (22R) or the core tube (11). From the retainer (R), the free cut end of the stretchable coil (26) is stretched to the exposed adhesive surface (10F) of the roll adhesive tape (10) as shown in FIGS. What is necessary is just to roll on the surface of various cleaning objects (M), such as a bed and a carpet, for example, by winding in the rough spiral state with the space | interval pitch (P) to perform.

  If it does so, the said elastic coil (26) adhesive-integrated to the adhesive surface (10F) of the adhesive tape (10) in the temporarily fixed state will be the adhesive surface (10F) with respect to the surface of the cleaning target (M). In other words, the contact area is narrowly restricted, and as a result, it is possible to prevent the possibility that the fresh adhesive surface (10F) will stick out too much and be used up at an early stage. There is a convenience that can be done smoothly with little.

  Further, when the winding state of the stretchable coil (26) around the adhesive surface (10F) is released, the stretchable coil (26) is pulled back to the retainer (R) as shown in FIG. As a result of opening the pressure-sensitive adhesive surface (10F) infinitely in a tightly wound spiral state with a small diameter, the pressure-sensitive adhesive tape (10) whose adhesive strength has been reduced can be peeled off very easily in one round. By repeating such operations, the service life of the adhesive tape (10) can be extended.

  In the basic embodiment shown in FIGS. 1 to 7 and the first modified embodiment shown in FIG. 8, the grip cover (13) of the rolling operation handle (H) is gripped and rolled along the surfaces of various cleaning objects (M). A roll-shaped adhesive tape wound around the core tube (11) without using the rolling operation handle (H) as shown in the second modified embodiment of FIGS. It goes without saying that the above-mentioned effects can be achieved in the same manner even when a rolling operation to various cleaning objects (M) is performed while directly gripping only (10).

  Further, FIGS. 15 and 16 show a third modified embodiment corresponding to the above basic embodiment. In this embodiment, the rolling operation handle (H) gripped by the user is a long straight metal rod, and the lower end portion thereof is cut off. And a cut-off upper end portion of a short metal rod bent out of the horizontal pivot (14) are connected and integrated by a flexible joint (32).

  Since the flexible joint (32) comprises a coil spring of a metal wire closely wound in a spindle shape, if the rolling operation handle (H) is pressed down strongly, the flexible joint (32) can be freely bent and deformed. In combination with the fact that the rolling operation handle (H) is long (for example, about 80 cm) and the roll-shaped adhesive tape (10) is narrow (for example, about 8 cm), it is suggested from the use state of FIG. As shown, for example, even toward the narrow lower space of the furniture (F), various foreign substances are reliably removed from the surface of the cleaning object (M) while the roll-like adhesive tape (10) is rolled and inserted deeply. It can be removed and is very convenient.

  In addition, since the other structure in 1st-3rd modification embodiment is substantially the same as the said basic embodiment, only the corresponding code | symbol with FIGS. 1-7 is entered in the FIGS. The detailed explanation is omitted.
