To do.

  According to the roller type dust collector of the present invention, a new adhesive paper portion can be pulled out without touching the hand, which is very hygienic. Moreover, in the roller type dust collector of the present invention, it is not necessary to tear off the used adhesive paper portion, so that the cleaning time can be shortened and the time for cleaning can be reduced. Furthermore, since the roller type dust collector of the present invention has a simple structure, the roller type dust collector can be manufactured at a low cost and is less likely to break down.

  Next, a roller type dust collector according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a perspective view of a roller type dust collector according to a preferred embodiment of the present invention. A roller-type dust collector according to a preferred embodiment of the present invention, indicated as a whole by the reference numeral 10 in FIG. The support frame 12 includes a pair of first member 14 and second member 16 that face each other, and a third member 18 that connects one ends of the first member 14 and the second member 16, and is substantially in plan view. It is shaped into a U shape. The support frame 12 is formed of an appropriate material such as a synthetic resin material or a metal material.

  Preferably, the first member 14 of the support frame 12 has a base portion 14a on the third member 18 side, and a tip portion 14b rotatably attached to the base portion 14a by a pin 14c, with the pin 14c being the center. As shown in FIG. 5B, the first member 14 can be brought into a “half-folded state” by rotating the tip portion 14b. Similarly, the second member 16 of the support frame 12 also has a base portion 16a on the third member 18 side and a tip end portion 16b rotatably attached to the base portion 16a by a pin 16c, and the pin 16c is the center. As a result, the second member 16 can be brought into a “half-folded state” by rotating the tip portion 16b.

  The roller-type dust collector 10 also includes a first shaft 20 rotatably attached to a distal end side between the first member 14 and the second member 16 of the support frame 12, and a first member 14 of the support frame 12. And a second shaft 22 rotatably mounted on the third member 18 side between the second member 16 and the second member 16.

  The first shaft 20 has a cylindrical peripheral surface portion 20a and disc-shaped end surface portions 20b and 20c at both ends. Preferably, a slit 20d is provided along the length direction of the peripheral surface portion 20a of the first shaft 20, and a notch 20e continuous with the slit 20d is also formed on one end surface portion 20b of the portion where the slit 20d is provided. (In other words, the other end surface portion 20c is not provided with a cut). As a result, as will be described in detail later, it becomes easier to attach the roll-shaped adhesive paper to the first shaft 20 and the roll-shaped adhesive paper is less likely to fall off.

  Further, projections 20b1 and 20c1 for fitting into the first member 14 of the support frame 12 and the holes 14d1 and 16d1 of the second member 16 are attached to the end surface portions 20b and 20c of the first shaft 20, respectively. The diameters of the holes 14d1 and 16d1 are formed to be slightly larger than the diameters of the protrusions 20b1 and 20c1 so that the shaft 20 can be easily rotated. Preferably, as shown in FIG. 3 (a), the first shaft is formed by housing the spring 20b2 inside one of the protrusions 20b1 so that the protrusion 20b1 can be retracted (see FIG. 3 (b)). 20 can be removably attached to the support frame 12.

  Similarly to the first shaft 20, the second shaft 22 also has a cylindrical peripheral surface portion 22a and disk-shaped end surface portions 22b and 22c at both ends. Preferably, a slit 22d is provided along the length direction of the peripheral surface portion 22a of the second shaft 22, and a notch 22e continuous with the slit 22d is also provided at one end surface portion 22b of the portion where the slit 22d is provided. (In other words, the other end surface portion 22c is not provided with a cut). Thereby, it becomes easy to mount the roll-shaped adhesive paper on the second shaft 22, and the roll-shaped adhesive paper is difficult to drop off.

  Further, projections 22b1 and 22c1 for fitting into the first member 14 of the support frame 12 and the holes 14d2 and 16d2 of the second member 16 are also attached to the end surface portions 22b and 22c of the second shaft 22, The diameter of the hole 16d2 is formed to be slightly larger than the diameter of the protrusion 22b1 so that the shaft 22 can be easily rotated (the diameter of the hole 14d2 is keyed to the hole 14d2, as will be described later). Since the protrusion 22c1 needs to be inserted, the protrusion 22c1 has a large shape. Further, similarly to the first shaft 20, preferably, the second shaft 20 is supported on the support frame 12 by accommodating a spring (not shown) inside the one protrusion 22b1 so that the protrusion 22b1 can be retracted. It can be removably attached to.

  The roller dust collector 10 also includes a tension applying device 24 for applying a constant tension to the rolled adhesive paper so that the rolled adhesive paper does not loosen during use. As shown in FIG. 4, the tension applying device 24 includes a disc 24 b accommodated in the halved cases 24 a 1 and 24 a 2. The case 24a2 is fixed to the base portion 14a of the first member 14 (see FIG. 4B). A protruding piece 24b1 is provided at the center of the disc 24b, and the protruding piece 24b1 is fitted into a hole 24a20 provided in the center of the case 24a2 so that the disc 24 rotates around the protruding piece 24b1. Yes. On the other hand, a flange 24b2 is provided on the periphery of the disk 24b, and a spiral spring 24c is disposed on the side of the disk 24b surrounded by the flange 24b2. Thus, after the spiral spring 24c is wound and tensioned in a state in which the disc 24b is fixed so as not to rotate, when the fixation of the disc 24b is released, the disc 24b is moved by the elastic force that the spiral spring 24c tends to relax. It rotates around the protruding piece 24b1. On the other hand, the protrusion 22c1 (with the key 22c2, see FIG. 2B) of the second shaft 22 is in the hole 24b3 (with the key groove 24b4) provided in the protruding piece 24b1 of the disc 24, and the key 22c2 is the key groove 24b4. Therefore, when the disk 24b rotates, the rotational force is transmitted to the second shaft 22.

  A handle 24d for winding and tensioning the spiral spring 24a accommodated in the cases 24a1 and 24a2 is disposed outside the case 24a.

  The tension applying device 24 is provided with a tension applying release mechanism 26 for releasing the application of tension. As shown in FIG. 5, the tension applying release mechanism 26 includes a rectangular space 26 a provided in the base portion 14 a of the first member 14, and a space so as to slide in the horizontal direction in the space 26 a. 26a, a sliding member 26b arranged in 26a, a spring 26c for pressing the sliding member 26b toward the tip member 14b, and a groove provided in the base portion 14a, and one end fixed to the sliding member 26b. The other end has an arm 26d extending to the boundary between the base portion 14a and the distal end portion 14b.

  In order to operate the tension application release mechanism 26, the first member 14 and the second member 16 may be set in a “half-folded state”. That is, when the first member 14 is in the “folded state” (see FIG. 5B), the tip member 14b does not prevent the movement of the arm 26d. The arcuate opening 26b1 of the sliding member 26b is locked to the protruding piece 24b1 of the disk 24b of the tension applying mechanism 24, and the rotation of the disk 24b is prevented. On the other hand, when the first member 14 is in a straight line state (see FIG. 5A), the movement of the arm 26d is prevented by the tip member 14b against the spring force of the spring 26c, and the arc-shaped opening of the sliding member 26b. 26b1 moves away from the protruding piece 24b1, and the rotation of the disk 24 is allowed, thereby returning to the tensioned state.

  In addition, in order to make the arc-shaped opening 26b1 engage with the protruding piece 24b1, a notch is provided on the inner periphery of the arc-shaped opening 26b1 and the outer periphery of the protruding piece 24b1 so as to mesh with each other.

  The roller dust collector 10 further includes a handle 28 attached to the third member 18 of the support frame 12.

  The use of the roller dust collector 10 configured as described above will be described. The roller dust collector 10 is used when a new roll-shaped adhesive paper is attached to the first shaft 20 (see FIG. 6A, hereinafter referred to as “first case”), and when a new roll-shaped adhesive paper is used. In the case of mounting on the two shafts 22 (see FIG. 6B), it is roughly divided into two types, hereinafter referred to as “second case”.

  First, the first case will be described. First, in a state where the handle 24d of the tension applying device 24 is turned and the spiral spring 24c is substantially completely tensioned, the roll-shaped adhesive paper is attached to the first shaft 20, and the end of the roll-shaped adhesive paper is pulled out. The sheet is inserted into the slit 22d of the second shaft 22, and the roll-shaped adhesive paper is placed on the floor and advanced. Then, the dust on the floor surface adheres to the adhesive paper, and the adhesive paper to which the dust adheres is wound around the second shaft 22. At that time, in the tension applying device 24, the spiral spring 24c tries to relax, so that the disk 24b rotates. This rotation is transmitted to the second shaft 22 and tries to pull the roll-shaped adhesive paper toward the second shaft 22. Therefore, the adhesive paper between the first shaft 20 and the second shaft 22 does not loosen. When the cleaning is completed or when the cleaning is to be temporarily interrupted, the first member 14 and the second member 16 of the support frame 12 are folded. Then, as described above, the arc-shaped opening 26b1 of the sliding member 26b is locked to the protruding piece 24b1 of the disk 24b, and the rotation of the disk 24b (therefore, the second shaft 22 interlocked with the rotation of the disk 24b). Therefore, the adhesive paper is not wound around the second shaft 22. As long as some dust adheres to the adhesive paper, the adhesive strength of the adhesive paper portion can still be expected, so the floor surface can be moved forward and backward several times, and the dust adheres to the adhesive paper. It is economically advantageous to advance the first shaft 20 so that the adhesive paper portion is sent out toward the second shaft 22 when it is no longer present.

  Next, the second case will be described. First, unlike the first case, in a state where the spiral spring 24c of the tension applying device 24 is substantially completely relaxed, the roll-shaped adhesive paper is attached to the second shaft 22, and the end of the roll-shaped adhesive paper is attached. The sheet is pulled out and inserted into the slit 20d of the first shaft 20, and the roll-shaped adhesive paper is placed on the floor surface and advanced. Then, the dust on the floor surface adheres to the adhesive paper, and the adhesive paper to which the dust has adhered is wound around the first shaft 20. At that time, in the tension applying device 24, the spiral spring 24 c is wound and tensioned according to the degree of rotation of the disk 24 b (and hence the second shaft 22). The tension which tries to pull in the direction acts. When the cleaning is completed or when the cleaning is to be temporarily interrupted, the first member 14 and the second member 16 of the support frame 12 may be folded in the same manner as in the case of the first case. .

  Note that the spring force of the spiral spring 24c is that the roll-shaped adhesive paper is transferred from one shaft to the other shaft (that is, from the first shaft 20 to the second shaft 22 or from the second shaft 22 to the first shaft 20). Upon transfer, the spiral spring 24c is selected from a substantially complete tension state to a substantially complete relaxation state, or from a substantially complete relaxation state to a substantially complete tension state.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say, it is something.
