Oval cylindrical adhesive cleaner

Abstract

[Problem] To make and inexpensively provide an elliptic-cylindrical adhesive cleaner with a simple mechanism with which it is possible to perform cleaning in a hygienic manner by bringing up dust and dirt and without leaving an uncleaned part, and which is easy to use against a wall or in a narrow space. [Solution] Provided is a cleaning tool in which a roll-shaped adhesive sheet is attached to a holder that has an arm with a grip as a supporting shaft, the holder having a generally elliptic-cylindrical shape and being provided with elongate hole-shaped slide bearings coaxially penetrating therethrough. A roll-shaped adhesive sheet which has been crushed in an elliptic-cylindrical shape is attached to the holder, whereby, each time the sheet is rolled, a series of actions is repeated in which the supporting shaft slides along the inner peripheries of the bearings, allows the elliptic cylindrical holder to roll, and then slides again. In addition, a shaft locking hole and an engaging concave portion are provided in the front side and the rear side of the elliptic cylindrical holder, respectively. By pressing an arm side-groove portion into the engaging concave portion, the tip-end of the shaft is simultaneously loosely inserted into the shaft locking hole, and the rotation is stopped.

Description

[Technical Field]

[0001] The present invention relates to a cleaning tool that rolls a rolled adhesive sheet to adhere and clean dust and dirt, and particularly to a technique for cleaning uneven fibrous surfaces such as carpets. [Background technology]

[0002] There is a cleaning tool that has a cylindrical holder attached to an arm with a handle formed by bending a round metal bar, and a detachable cylindrical adhesive sheet attached to the holder.When the adhesive strength weakens due to dust or dirt, one sheet can be peeled off to reveal a new adhesive surface, making it reusable.

[0003] However, with conventional cylindrical adhesive cleaners, on uneven fibrous surfaces such as carpets, only the surface dust and dirt could be cleaned, leaving a dissatisfied feeling of accomplishment. Furthermore, on floor surfaces such as near walls, the cylindrical diameter of approximately 4 to 5 cm had an effect, and a gap of about that radius would be created between the floor where the adhesive surface came into contact and the wall where it ended, leaving behind areas where dust and dirt could not adhere.

[0004] To address these issues, Patent Document 1 proposes improving on these by making the rotation axis of the adhesive sheet roll eccentric or by making the cross-sectional shape oval or polygonal, allowing the roll to bounce up and down while it rolls, knocking and lifting up the dirt for cleaning, while Patent Document 2 proposes making the cross-sectional shape of the dirt removal roll polygonal or spindle-shaped, using the corners to reduce the amount of dirt left behind along walls, etc. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Utility Model Registration No. 3170444 [Patent Document 2] Utility model registration No. 3167351 Summary of the Invention [Problem to be solved by the invention]

[0006] However, when used on fibrous surfaces such as carpets, the adhesive surface would bounce around the floor when rolled, kicking up dust and leaving patches of dust behind. Also, when used on areas near walls, the dust removal roll would swing around the axis of the arm, making it difficult to apply the adhesive surface exactly where desired.

[0007] Furthermore, both proposals had the uneconomical aspect of requiring the sheet to be replaced sooner, as the angular cross-sectional shape of the rolled adhesive sheet and the eccentric shaft caused strong intermittent resistance to rotation. If the adhesive strength weakened even slightly due to dust or dirt, the sheet would stop rotating and slide along the floor.

[0008] The present invention aims to solve these problems and to provide an elliptical cylindrical adhesive cleaner with a simple mechanism that is easy to handle and enables efficient hygienic cleaning at a low cost. [Means for solving the problem]

[0009] In order to achieve the above object, claim 1 of the present invention provides a cleaning tool in which a rolled adhesive sheet is attached to a holder with a handle-equipped arm as a support shaft and rolled around, the holder has an elliptical cylindrical shape and a long-hole sliding bearing is provided coaxially with the holder, a rolled adhesive sheet that has been compressed into an elliptical cylindrical shape is attached to the holder, and each time the holder is rolled, the arm's support shaft slides on the inner circumference of the bearing, causing the elliptical cylindrical holder to rotate and slide again, repeating a series of movements.

[0010] As a result, when the shaft of the arm slides over the long-hole sliding bearing of the elliptical cylindrical holder and approaches the inner end, it begins to rotate, and at the same time the elliptical cylindrical adhesive sheet stands up, and then the impact of the forceful fall accompanied by a shift in the center of gravity and wind pressure causes air vibrations.

[0011] In claim 2, the support shaft of the elliptical cylindrical holder is a cantilever arm with a handle, and an axis stop hole is provided at the front of the elliptical cylindrical holder and a hooking recess is provided at the rear.By pushing the arm side groove into the hooking recess, the tip of the shaft is loosely inserted into the axis stop hole in tandem, stopping the rotation.

[0012] This restricts the movement of the elliptical cylindrical holder in front of and behind the axis of the cantilever arm, and it is further held by the side of the arm that is bent at a right angle from the axis, meaning that the three vertices of a right triangle are supported, preventing rotation.

[0013] In claim 3, the support shaft of the elliptical cylindrical holder is a double-supported arm with a handle, and a curved section is formed just before the arms branch off from the handle side, and an arm clip is placed at that position to bridge the gap.As the arm clip slides back and forth, the grip section on the arm side clamps and releases the locking claws on both ends of the elliptical cylindrical holder in tandem, allowing rotation control to be performed at hand.

[0014] This allows you to stop and restart rotation with one hand by sliding the arm clip back and forth with your thumb while holding the handle. [Effects of the Invention]

[0015] The oval cylindrical adhesive cleaner of the present invention has the following effects.

[0016] The present invention comprises an elliptical cylindrical holder with an elliptical cylindrical adhesive sheet attached to it, and by using a long-hole sliding bearing for the bearing, it is possible to produce a rotation with varying speed while maintaining a nearly constant distance between the axis and the floor surface when rolled, so that the sheet does not bounce with violent up and down movements and does not leave spots of dust or dirt behind.

[0017] This varying speed of rotation causes the oval cylindrical adhesive sheet to fall forcefully, lifting out dirt, dust, and loose hair, which is then immediately covered with the wide, gently curved surface of the adhesive sheet, and then slowly sticks it back down without missing anything.This modulated movement allows for hygienic cleaning while efficiently preventing dust from flying up, making it especially effective as a measure against house dust in homes with pets.

[0018] In addition, when cleaning corners near walls or stairs, the elliptical cylindrical adhesive sheet can be easily handled by stopping its rotation by pointing the sharply curved surface in the direction of the handle, and even in narrow spaces, the sticky surface can be pressed against the sheet as desired with the swinging motion stopped, allowing the dust and dirt to adhere and be collected.

[0020] The present invention has two different arm shapes depending on the method of supporting the elliptical cylindrical holder so that it can rotate and slide, and these will be described with reference to the drawings of the embodiments. [Example]

[0021] FIG. 1 is a perspective view showing the rotational state of the first embodiment of the present invention. A cantilever arm 1 formed by bending a round metal bar extending from a handle portion 1a has its shaft portion 1b loosely inserted into an elliptical cylindrical holder body 9 and is subjected to the pulling force of a coil spring 5 at the rear, and the shaft tip portion 1c is rotatably retained by a retaining ring 3 at the position of a long-hole-shaped plain bearing plate 9a at the front.

[0022] The elliptical cylindrical holder main body 9 is basically made by molding resin, and consists of two long-hole-shaped sliding bearing plates 9a arranged side by side at the front and back, and two reinforcing side plates 9e that connect them together to form a single unit.Furthermore, an axis stop hole plate 9d is provided at the front to prevent rotation, and a locking recess 9c is provided at the rear, and a locking claw portion 9b is protruded at the front end to prevent the elliptical cylindrical adhesive sheet 10 from falling off.

[0023] 2 shows the AA cross section and the rotational trajectory showing the movement of the present invention when it is rolled, and the opposing support wing parts 9f of the elliptical cylindrical holder main body 9 are attached to support the elliptical cylindrical adhesive sheet 10 from the inside using the flexibility and repulsive force of the resin. The elliptical cylindrical adhesive sheet 10 is made by first flattening the cylindrical roll-shaped adhesive sheet and then fitting the part that is about to return to its original shape onto the outside, and the restoring force and the repulsive force of the support wing parts 9f balance each other to hold the sheet in place, absorbing any gaps or distortions that occur during the deformation process and enabling it to be attached without any rattle.

[0024] The dotted lines also represent the rolling of the elliptical cylindrical adhesive sheet 10 when the arm shaft 1b is moved at equal intervals. The shaft 1b moves back and forth within the rotational sliding range of the inner circumference of the long-hole sliding bearing plate 9a, and moves as shown by the shaft movement trajectory 11 while maintaining an almost constant distance to the carpet floor surface 12, so it does not bounce on the floor surface.

[0025] This movement has a rational characteristic, and the rolling speed of the elliptical cylindrical adhesive sheet 10, which is accompanied by a shift in the center of gravity, is fast in the rotational range from upright to tipping over, and slow in the subsequent sliding range, as shown by the concentration of the dotted lines that indicate the trajectory of the shaft portion 1b when it moves at equal intervals.

[0026] Incidentally, the long-hole bearing of the elliptical cylindrical holder body 9 is a hole in the shape of two semicircles connected by a straight line, and is opened arbitrarily on the long axis if the cross section of the holder is roughly elliptical. If this bearing hole is made elliptical in shape similar to the cross section of the elliptical cylindrical adhesive sheet 10, there will be no up and down movement and the rolling will be even smoother, but the impact force will also be softer and the knocking effect will be halved.

[0027] Figure 3 is a front view showing the rotational state of the first embodiment of the present invention, in which the arm side groove portion 1d moves away from the latch recess 9c protruding from the rear of the elliptical cylindrical holder main body 9, and the shaft tip 1c with the retaining ring 3 attached is pulled back by the repulsive force of the coil spring 5 interposed between the retaining ring 3 at the rear of the shaft and the elongated hole-shaped plain bearing plate 9a, and is latched in a rotatable state to the front elongated hole-shaped plain bearing plate 9a.

[0028] FIG. 4 is a B-B cross-sectional view showing the rotation-stopped state in the first embodiment of the present invention, in which the arm side groove 1d is inserted into the retaining recess 9c protruding from the rear of the elliptical cylindrical holder main body 9, and in conjunction with this, the arm shaft tip 1c is loosely inserted into the front shaft stop hole plate 9d, and rotation is stopped by three-point support including the coil spring 5 at the rear of the shaft. [Example]

[0029] Figure 5 is a perspective view showing the rotation-stopped state in the second embodiment of the present invention. The double-supported arm 2, formed by bending a metal round bar, passes through a pair of handle portions 2a from its rear end bent into a U shape, passes through a curved portion 2d bridged by an arm clip 6, and then branches out to the left and right. One of the arms acts as a support axis and passes through the elliptical cylindrical holder body 9, and is joined by the joining end 2c coming from the other end at the connecting pipe 7 at its tip, where it is inserted loosely.

[0030] The elliptical cylindrical holder body 9 is basically made by molding resin, and consists of two long-hole-shaped sliding bearing plates 9a arranged side by side in front and behind, and two reinforcing side plates 9e that connect them together to form a single unit.Furthermore, locking claw portions 9b protrude from both ends to stop rotation and prevent the elliptical cylindrical adhesive sheet 10 from falling off.

[0031] In addition, the arm clip 6 is positioned on the curved portion 2d of the double-supported arm 2, and the arms, which are biased in the direction of separation by the elastic range of the metal, are in a state where they are drawn closest to each other.In conjunction with this, a pair of arm-side grip portions 8, which have an anti-slip function, clamp the locking claw portions 9b on both ends of the elliptical cylindrical holder main body 9 from both sides, stopping the rotation.

[0032] 6 is a perspective view of the second embodiment of the present invention when replacing the elliptical cylindrical adhesive sheet 10. By twisting and removing the arm clip 6, the double-supported arms 2 are released from their bias and spread apart, and at the same time, the joint end 2c falls out of the connecting pipe 7 and is released, allowing the elliptical cylindrical adhesive sheet 10 to be pulled out of the elliptical cylindrical holder body 9 and replaced. The diagonal reinforcing ribs of the reinforcing side plate 9e are designed to reduce snagging during replacement, making it easier to attach and remove.

[0033] Figure 7 is a B-B cross-sectional view showing the rotational state in the second embodiment of the present invention, in which the arm clip 6 moves from the curved portion 2d toward the pair of handle portions 2a, weakening the force pulling the arms together, and the joint end portion 2c loosely inserted into the connecting pipe 7 comes out about halfway, and in conjunction with this, the arm side grip portion 8 moves away from the locking claw portion 9b of the elliptical cylindrical holder main body 9, making it rotatable.

[0034] Figure 8 is a B-B cross-sectional view showing the rotation-stopped state in the second embodiment of the present invention, in which the arm clip 6 moves onto the curved portion 2d just before the branch, drawing the arms together, and the joint end portion 2c loosely inserted into the connecting pipe 7 penetrates all the way in, and in conjunction with this, the arm side grip portion 8 clamps the locking claw portion 9b of the elliptical cylindrical holder main body 9 from both sides, stopping the rotation.
