Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an adhesive tape cleaner that removes dirt and grime from floors and carpets using adhesive tape. This invention relates to an adhesive tape cleaner that winds a tape and has an adhesive tape supply and winding shaft built into the cylindrical body.

[Technical Background of the Invention] An adhesive tape roller, which is made by winding an adhesive tape with an adhesive on one side with the adhesive side facing outward, is rotated on the floor or carpet, and the adhesive is used to remove dirt and dust. Various types of adhesive tape cleaners that are attached to tapes have been conventionally provided.

A typical configuration of such an adhesive tape cleaner is that a core material is rotatably supported at one end, and an adhesive tape roller with adhesive tape wound multiple times is fitted onto the core material of a shaft that serves as a grip at the other end. There is a combination.

When using the adhesive tape, hold it by the hand and rotate the adhesive tape roller on the floor or carpet to remove dust, etc. If the adhesive effect deteriorates due to adhesion of M, etc., cut off one circumference of the dirty outer adhesive tape.

Trying to position new adhesive tape.

Adhesive tapes are provided with cuts and perforations in advance to make it easier to cut off dirty adhesive tapes when the adhesive strength decreases. Therefore, although it is easy to cut a dirty adhesive tape, the dirty part of the adhesive tape must be touched when cutting, which is unsanitary. In particular, as the adhesive tape approaches its end, the diameter of the adhesive tape roller becomes smaller and the circumferential area becomes smaller, so a cutting operation is often required.

Therefore, in recent years, a hollow cylindrical body is rotatably supported, and an adhesive tape supply and take-up shaft is housed in this cylindrical body, and after the adhesive tape from the supply shaft is wound around the outer periphery of the cylindrical body, the An adhesive tape cleaner wrapped around the take-up shaft is proposed.0 If the adhesive tape wrapped around the outer periphery of the cylindrical body becomes dirty, a cleaner is provided on the axial side of the cylindrical body and directly connected to the axis of the take-up shaft. The adhesive tape is rolled up by rotating the operating knob.

[Problems to be Solved by the Invention] However, the adhesive tape roller rotates while adhering to the floor, etc., although it is light, so simply supporting the two shafts rotatably will not work when cleaning the area. There is a possibility that it may be pulled out unnecessarily, so the rotation of the two shafts is locked during cleaning.

When winding, a mechanism is required to release the lock, which complicates the structure inside the cylinder.When storing a larger capacity adhesive tape, it is necessary to supply two shafts inside the cylinder and control the winding operation. To place it without disturbing it,
They must be arranged so that their axes are spaced apart in the diametrical direction of the cylinder, so that the axis of the winding shaft is located at a position offset from the axis of the cylinder on the side of the cylinder. As a result, when you try to rotate the operating knob, a force that rotates the cylindrical body is applied, so the winding Sometimes, the cylindrical body must be held firmly by hand to prevent it from rotating, and then the operating knob must be rotated, making it very inconvenient to use.

SUMMARY OF THE INVENTION An object of the present invention is to provide an adhesive tape cleaner in which an adhesive tape supply and take-up shaft is rotatably provided in a rotatable cylindrical body, in which the adhesive tape is not drawn out unnecessarily during cleaning, and the cylindrical body To provide an adhesive tape cleaner capable of winding and rewinding without touching the body.

[Means for Solving the Problems] The present invention provides an adhesive tape cleaner in which an adhesive tape is wound around the outer periphery of a rotatable cylindrical device, and an adhesive tape supply and take-up shaft is built into the cylindrical device. In this case, the cylindrical body device has first and second parts that can be opened and closed in a semi-cylindrical shape.
a hollow body, first and second sleeves extending coaxially at both axial ends of the cylindrical body device, a drive shaft coaxially and rotatably inserted into the first sleeve, and an outer side of the drive shaft. A winding knob provided at one end, a first drive gear located at the other end of the drive shaft and located within the cylindrical body device, and a first drive gear fixed to the first sleeve and elastically pressing the first winding knob outward at all times. The winding shaft is equipped with a spring material, and when the winding knob is pressed against the elastic force of the spring material at one axial end of the winding shaft,
a second drive gear meshing with the first drive gear; the supply and take-up shafts each include a ratchet gear portion;
One side of the second sleeve is provided with a meshing protrusion that elastically meshes with the ratchet gear, and the ratchet gear and the meshing protrusion are disengaged when winding up the adhesive tape. A cover device rotatably and detachably supports the first and second sleeves of the cylindrical body device and covers so as to expose at least a portion of the adhesive tape wound around the first cylindrical body device. A locking piece is formed on the side surface on the winding knob side and engages with a protrusion provided on the spring material to prevent rotation of the cylindrical body device when the winding knob is pressed. It is.

[For production] This is how the adhesive tape cleaner of this invention works.

First, the rotation of the cylindrical body device is prevented by pressing the winding knob provided at the shaft center of one axial end of the cylindrical body device so that the protrusion provided on the spring material is engaged with the locking piece of the cover device. . By then rotating the winding knob in this state, the rotation of the winding knob is transmitted from the drive shaft to the second drive gear and then to the second drive gear of the winding shaft, and the winding shaft can be rotated in the winding direction. This allows the new adhesive tape to be drawn out from the supply shaft and wound around the outer periphery of the cylindrical device at the same time as the old adhesive tape is wound onto the take-up shaft. After the new adhesive tape is wound around the outer circumference of the cylindrical body device, release the pressure on the winding knob, so that the winding knob will protrude outward due to the elastic force of the spring, and the threaded connection between the first and second drive gears will be released. is solved. In this way, the winding operation is performed by stopping the rotation of the cylindrical body device and pulling out a new adhesive tape without touching the cylindrical body device at all.゛Do it with 22.

The rotating cylindrical body device 3 inserted into the cover device 4 in this manner has the adhesive tape 2 wound around its surface with the adhesive side facing outward, so the adhesive tape 2 is rotated onto the floor or carpet. to attract dirt and dust. When the adhesive tape 2 comes into contact with the floor etc., peeling resistance may occur and the adhesive tape 2 may be pulled out from the supply shaft 43 and the take-up shaft 49, but these shafts 43 and 49 are connected to their ratchet gears. The portions 66 and 76 form a mating protrusion 86.
88, it will not spin idly and the adhesive tape 2 will not be drawn out unnecessarily.

When the adhesiveness of the adhesive tape 2 is reduced due to adhesion of dust, etc., the winding knob 81 is pressed against the elastic force of the stopper 82 toward the side surface 101 of the cover main body 100. As a result, the locking protrusion 83 of the stopper 82 engages with the locking protrusion 107 provided on the side surface 101. Since the stopper 82 is fixed to the sleeve 78, rotation of the hollow bodies 11 and 12 is restricted. At the same time, the second drive gear 77 attached to the tip of the drive shaft 79 of the winding knob 81 also moves to the fifth gear.
It is pushed into the interior as shown by the horizontal arrow in the figure, and at this time, its outer peripheral edge engages with the push-down locking piece 85 of the ratchet spring 84, pushing the ratchet spring 84 downward in FIG. As a result, the ratchet gear portion 76 of the supply shaft 43 is disengaged from the meshing protrusion 86 . On the other hand, as the second drive gear 77 moves forward, this gear 77 meshes with the first drive gear portion 67 of the winding shaft 49 . In this state, when the winding knob is rotated clockwise as shown in FIG. 2, the rotation is transmitted from the second drive shaft to the first drive shaft 67, and the winding shaft 49 is rotated counterclockwise as shown in FIG. Rotate clockwise to wind up the adhesive tape 2. The ratchet gear part 76 of the winding shaft 49 is formed so as to go over the meshing protrusion 88 when rotating counterclockwise and Q, so that the rotation is not blocked. After positioning a new adhesive tape 2 on the outer peripheral surface of the rotating cylindrical device 3 in this way, it can be used again (1°) Meanwhile, the supply shaft 43 rotatably supported by the two hollow bodies 11 and 12 And the winding shaft 49 has a bearing notch 44
．． 45.51.52 are always elastically pressed in one direction by the spring protrusions 46.53 and 54 provided near the shaft holding protrusions 55.56 of the hollow body 12 or 11.
Since it is also supported by the angle 57, the shafts 43 and 49 can be rotated without wobbling, and the adhesive tape 2 can be prevented from meandering. In this case, the bearing cylindrical portion 65.69°75 of the presser projection 55.56.57
By forming the distal end in contact with the bearings on the same circumferential surface as the circumferential surface of the cylindrical bearing portion, it can be held more reliably. Further, when winding up the adhesive tape 2, the meshing between the ratchet gear portion 76 of the supply shaft 43 and the meshing protrusion 86 is released;
The supply shaft 43 is in a free state, but since the adhesive member 94 of the tape presser 91 elastically presses the adhesive tape 2, the supply shaft 43 rotates idly due to the winding operation, causing the adhesive tape 2 to sag. I won't let you.

When the adhesive tape 2 on the supply shaft 43 is used up, open the rotating cover member 111 fully and release the locking lever member 124.
129 to remove the rotating cylinder device 3 from the cover device 4. Next, the knob 22
．． 26 to open the hollow body 11.12.

Remove the supply shaft 43 and the take-up shaft 49 from the hollow body 11.12,
A supply shaft 43 around which a new adhesive tape 2 is wound and a take-up shaft 49 around which the tip of the adhesive tape 2 is wound are inserted.

Gear bushings 62) 7 of the supply shaft 43 and take-up shaft 49
3 and bushings 63.74 are removably fitted to the sleeve 61.72, so spare adhesive tape 2.
It is also possible to sell the product wound around the sleeve 72 of the supply shaft 43, and use the gear bushes 62, 73 and 63, 74 that were originally attached. In addition, since the adhesive surface of the adhesive tape 2 is in contact with the sleeve 61 of the take-up shaft 49, it can be tightly wound. It can be used as a 49 sleeve.

By doing so, the spare adhesive tape can be sold in a state wound around the sleeve 72 of the supply shaft 43, and since the gear bushing and bushing can be omitted, it can be provided at low cost.

By constructing the inner walls 41, 42, 47, 48 from synthetic resin, the spring protrusions 46, 53, 54 and the open spring member 60 can be integrally formed by cutting a part of these inner walls.

[Effects of the Invention] As described above, the adhesive tape cleaner of the present invention includes a cylindrical device rotatably supported by a cover device, and a repressible winding knob provided in the axial center of one end in the axial direction of the cylindrical device. ,
A first drive gear is provided on the shaft of a winding knob located within the cylindrical body device, and is meshed with a second drive gear of a winding shaft located within the cylindrical body device. The adhesive tape is wound up by rotating it while pressing it. Since the rotation of the cylindrical device is locked when the winding knob is pressed inward, the adhesive tape can be wound up without having to touch the cylindrical device, which is sanitary. In addition, the inside of the cylindrical device also includes a winding shaft equipped with a ratchet gear part and a drive gear part to prevent slipping, a supply shaft equipped with a ratchet gear part to prevent slipping, and a main shaft fixed to the shaft of the winding knob. Since it has a simple configuration with only a driving gear, it can be lightweight and provided at low cost.
