[0008]

The present invention will be described in detail below with reference to the embodiments shown in the drawings. 1 and 2, an adhesive carpet cleaner according to the present invention has opposite side plates 1 and 1'which are spaced apart by bosses 2 and 3 and 2'and 3 '(not shown). The shaft 4 is supported integrally by the boss 2 of one side plate 1 and the boss 2'of the other side plate 1'and the shaft 4 is supported by the boss 3 of one side plate 1 and the other side plate 3'of the other side plate 1 '. 5 are supported.

Since the relationship between the shaft, the boss, the supporting roller described later, and the brake unit is the same for the shafts 4 and 5,
Only described with respect to axis 4. The boss 2 of the side plate 1 and the shaft 4 are fitted by forming a groove at one end of the shaft 4 to bulge the periphery and then press-fitting the shaft 4 into the boss 2. The boss 2'and the boss 2'can be fitted to each other by slightly reducing the diameter of the shaft 4 so that the adhesive tape winding body can be easily replaced. In this case, the side plates 1 and 1 '
It can be molded from plastic as the same part.

In FIG. 1, a support roller 6 for the adhesive tape is rotatably mounted on one end of the shaft 4, and another support roller 7 is rotatably mounted on the opposite end of the shaft 4. Has been done. A long collar 8 is interposed between the two support rollers 6 and 7. An adhesive tape winding body 10a wound around a winding core 9 is attached to the support rollers 6 and 7 at both ends attached to the shaft 4, and a groove is formed on the outer peripheral surface of one of the support rollers 6 to form a ridge. Then, the core 9 can be press-fitted. As can be seen from FIG. 2, only the winding core 9 is attached to the supporting rollers 6 ', 7'of the other shaft 5 by press fitting.

Each side plate 1, 1'has two shafts 4 and 5
Pins 15 projecting to the opposite side of the boss on a centerline C that bisects the distance between the two axes in a plane orthogonal to
15 'is formed. These pins 15, 15 'are fitted with holes at the ends of the strip-shaped holders 16, 16', which extend upwards and are bent towards each other and held together by a ring 17 which is fitted with a plastic handle 18. It is constructed by inserting it into the hole. In addition, ring-shaped protrusions 19 and 19 'are provided around the pins 15 and 15' of the side plates 1 and 1 ', and the ends of the holders 16 and 16' are protruded by the spring action as shown in FIG. Parts 19, 1
If the end portions of the shafts 4 and 5 and the bosses 2'and 3'of the side plate 1'are slip-fitted, the shafts 4 and 5 are held so as not to rattle in the axial direction.

Further, as can be seen from FIG. 2, the side plates 1 and 1'include at least the lower outer peripheral surface of the adhesive tape winding body 10a and the empty core on the center line C between the shafts 4 and 5. A fulcrum S protruding downward from a tangent line connecting the lower outer peripheral surface is formed. In FIG. 2, when the handle 18 is pushed to the left, the side plates 1 and 1'rotate to the left around this fulcrum S, the empty core 9 contacts the carpet, and the adhesive tape winding body 10a moves to the carpet. Lifted from the handle 18
When is pushed to the right, the side plates 1, 1'rotate to the right, the adhesive tape winding body 10a comes into contact with the carpet, and the empty winding core 9 is lifted. Further, as shown in FIG. 2, the lower edges of the side plates 1 and 1'must be positioned so as to be slightly retracted from the outer circumference of the winding core 9 so that the empty winding core 9 can come into contact with the carpet.

Further, as is apparent from FIG. 1, the adhesive tape 10 extending from the adhesive tape winding body 10a to the outer circumference of the winding core 9 is provided with tension inside the support roller 7 in order to apply tension so as not to slacken constantly. Is provided with a brake unit 20 on the shaft 4 adjacent to the boss 2'of the side plate 1 '.

Two embodiments of the brake unit are shown in FIGS. 5, 6 and 7. In the embodiment shown in FIGS. 5 and 6, the brake unit 20 includes a brake desk 21 press-fitted into the shaft 4 and a brake pivotally attached to a pin 22 protruding in parallel to the axial direction from the brake desk 21. It comprises a shoe 23 and a spring 25 that is mounted around a pin 24 that projects inward from the tip of the brake shoe 23 and that always urges the brake shoe 23 radially outward.

In FIG. 5, when the support roller 7 rotates counterclockwise, the brake desk 21 fixed to the shaft 4 does not rotate. Therefore, the spring acting on the contact point between the brake shoe 23 and the inner peripheral surface of the support roller. In the opposite direction to the moment of force by 25, the moment of an external force that tries to rotate the brake shoe 23 against the spring 25 by the rotation of the support roller 7 acts, and as a result, the inner surface of the support roller by the brake shoe 23 acts. The acting force is reduced and therefore the friction force is reduced, and the support roller 7 receives a relatively small braking force to rotate. On the contrary, when the support roller 7 rotates in the clockwise direction, in addition to the moment of the force acting on the brake shoe 23 by the spring 25, the moment of the external force due to the clockwise rotation of the support roller 7 acts on the brake shoe 23. The force of pressing the inner peripheral surface of the support roller 7 of the shoe 23 increases, and thus the frictional force increases, and the support roller 7 receives a relatively large braking force and rotates. Therefore, in FIG. 2, when the adhesive carpet cleaner moves in the direction of the arrow B, the support roller 7 serving as the front wheel is formed.
Since the brake unit 20 receives a small braking force and the support roller 7 serving as a rear wheel receives a large braking force, a tensile force pulling the adhesive tape 10 rearward is generated and the adhesive tape is tensioned. When the adhesive carpet cleaner is moved in the direction of arrow A, the braking force is opposite to the above,
Similarly, tension that pulls the adhesive tape 10 backward is generated.

Next, the brake unit 3 of the second embodiment
0 will be described with reference to FIG. This brake unit 30
Is a brake desk 31, a rib 32 extending integrally with the brake desk 31 in the radial direction, and a length of approximately one round along the outer circumference of the rib 32 independently from the tip of the rib 32 and separated from the brake desk 31. The brake band 33 extends along the length, and a spring 34 mounted between the free end 33 a of the brake band 33 and the rib 32. In this embodiment, the spring 34 generates a force to spread the band 33 in the circumferential direction, the outer peripheral surface of the band 33 is pressed against the inner peripheral surface of the support roller 7, and a braking force acts. In FIG. 7, when the support roller 7 rotates counterclockwise,
Since the external force generated by the rotation of the support roller 7 acts in the direction opposite to the circumferential force generated by the spring 34, the frictional force between the band 33 and the support roller 7 decreases. When the support roller 7 rotates counterclockwise, the band 33 generated by the spring 34 is rotated.
In addition to the force for expanding, the frictional force between the band 33 and the inner peripheral surface of the support roller causes an external force for rotating and expanding the band 33 in the clockwise direction, so that the braking force on the support roller 7 is large. Become.

It is preferable that the support roller, the side plate, the brake desk, the brake shoe, the brake band, and the like are made of plastic because they are lightweight. Moreover, it is preferable that the shaft, the holder, the spring and the like are made of a metal material. As the adhesive tape, known adhesive tapes and adhesive processed papers that are commercially available for adhesive carpet cleaners can be used.

The operation of the adhesive carpet cleaner thus constructed will be described. First, in FIG. 1, the holder 1
6, 16 'are pulled outwards from each other to disengage them from the pins 15, 15' of the side plates 1, 1 ', and then the side plate 1'is pulled outward and removed from the shafts 4, 5. For example, one axis 4
The adhesive tape winding body 10a wound around the winding core 9 is mounted on the upper supporting rollers 6 and 7, and only the empty winding core 9 is mounted on the supporting rollers 6'and 7'on the other shaft 5. . then,
Again, the bosses 2'and 3'of the side plate 1'are fitted on the shafts 4 and 5, respectively.

Adhesive tape winding body 1 having an adhesive surface on the outside
The adhesive tape 10 is pulled out from 0a and extended to the lower side of the winding core 9 on the support rollers 6'and 7'as indicated by the two-dot chain line in FIG. Then, when the winding core 9 is rotated counterclockwise, the adhesive tape 10
2 is bent as shown by the alternate long and short dash line in FIG. 2, and finally the adhesive tape 10 having the adhesive surface on top is wound around the winding core 9 for one round. From this state, when the handle 18 is gripped and pushed in the direction A, the side plates 1 and 1'rotate counterclockwise in FIG. 2 around the fulcrum S to rotate the cores 9 on the supporting rollers 6'and 7 '. The upper adhesive tape 10 is pressed against the carpet, and the adhesive tape winding body 10a on the opposite side is lifted away from the carpet. When the handle 18 is pushed further, the core 9 on the side of the support rollers 6 ', 7'which are the front wheels is rotated, and the adhesive tape 10 fed from the adhesive tape winding body 10a is further wound around the core 9. The adhesive tape winding body 10b is formed. During this forward movement in the direction A, dust and hair adhere to the adhesive tape 10 on the front wheel side. During this forward stroke, the braking force of the brake 20 on the front wheel side becomes relatively small, and the braking force of the brake unit 20 on the rear wheel side becomes relatively large, so that tension from the front wheel side to the rear wheel side is generated and the adhesive tape The slack is prevented.

When the handle 18 is pushed in the B direction, the side plate 1,
1'rotates clockwise around the fulcrum S to press the adhesive tape winding body 10a on the supporting rollers 6, 7 side against the carpet, and the adhesive tape on the supporting rollers 6 ', 7'on the opposite side. The wound body 10b is lifted. When the tape is retracted in the B direction as it is, the adhesive tape 10 is rewound on the adhesive tape winding body 10a, and the adhesive tape 10 is unwound from the opposite side adhesive tape winding body 10b. This B
2, the braking force is reduced on the side of the support rollers 6 and 7 while the braking force is increased on the side of the support rollers 6'and 7 '. Tension is generated in the rearward direction to prevent the adhesive tape from sagging.

In this way, when the dust and hair on the carpet adhere to the same area of the adhesive tape 10 to such an extent that the adhesive strength of the adhesive tape is lost by reciprocating the adhesive tape 10 for a certain distance, the forward movement in the direction A ends. At this time, if it is lifted as it is, it is lowered onto the carpet, and the reciprocating movement is started again starting from the previous step, it is possible to remove the dust and the like on the carpet at the part of the new adhesive tape 10 which is not dusty yet.

[0022]

As described above, according to the present invention,
The side plate is rotated around the fulcrum S during the reciprocating movement of the adhesive carpet cleaner to remove dust on the carpet while automatically switching the adhesive tape winding body that is pressed against the carpet by alternately switching the used adhesive tape. Since it is possible to automatically wind up from one adhesive tape winding body to the other adhesive tape winding body or core, the work can be interrupted as in the past and the dust of used one round can be manually removed. This eliminates the need to tear off the attached adhesive tape and is extremely efficient. In addition, since the brake unit is provided in the support roller, tension is applied to the adhesive tape toward the rear wheel side toward the adhesive tape winding body during the reciprocating motion, so that the adhesive tape may be strained, and thus slack may occur. Without, the used adhesive tape can be wound up cleanly on the core.
