SUMMARY OF THE INVENTION A rotary brush 2 according to the present invention.
Has a large number of bristles 2B fixed radially to a bendable core wire 2A, and is used while rotating the core wire 2A. The rotating brush 2 has a flexible grooved wire 2C wound around a surface of a flexible core wire 2A. The grooved wire 2C is formed in a groove shape, and is fixed in the groove 23 with the hair 2B interposed therebetween. The channel-shaped wire 2C is fixed by being wound around the core wire 2A so that the bristles 2B are radial with respect to the core wire 2A. When the rotating brush 2 is used while being rotated while deforming the core wire 2A, the channel wire 2C and the core wire 2A are deformed together.

According to a second aspect of the present invention, the rotary brush is provided with a hard core portion which is hard and hardly deformed on the flexible core wire. A portion 2E is provided. Rotary brush 2 with these structures
Can be used by deforming a flexible and easily deformable portion in a state where the portion used in a straight line without deformation is less deformed or is not deformed.

Further, the rotary brush 2 according to claim 4 of the present invention.
Is used for an apparatus for cleaning the surface of the denture 4 by rotating the core wire 2A in a U-curved state.

Further, in the rotary brush 2 according to the fifth aspect of the present invention, a wire in which a wire 27 is inserted through a plastic tube 26 is used as the core wire 2A.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. However, the embodiments described below illustrate a rotating brush for embodying the technical idea of the present invention, and the present invention does not specify the rotating brush as follows.

Further, in this specification, in order to make it easy to understand the claims, the numbers corresponding to the members shown in the embodiments will be referred to as “claims” and “ In the column of “means”. However, the members described in the claims are not limited to the members of the embodiments.

The rotary brush 2 shown in FIG. 4 has a large number of bristles 2B radially fixed to a flexible core wire 2A so as to bend. The rotating brush 2 is used by rotating the core wire 2A in a curved state as shown by a chain line.

The core wire 2A does not directly fix the hair 2B. The bristle 2B is fixed to the core wire 2A via a flexible grooved wire 2C as shown in the enlarged sectional view of FIG. The groove-shaped wire 2C is formed in a groove shape, and bristles 2B are formed in the grooves 23.
Is fixed. The channel-shaped wire 2C is spirally wound around the surface of the core wire 2A so that the hair 2B is radial with respect to the core wire 2A, and fixes the hair 2B to the core wire 2A.

The groove-shaped wire 2C is required to have flexibility to bend together with the core wire 2A. Furthermore, durability that does not break even when repeatedly bent is required. To realize this, the channel wire 2C is made of nylon, polyethylene,
Molded with plastic such as polypropylene. The plastic channel is preferably molded from a thermoplastic plastic. The channel wire formed of thermoplastic plastic can be heated and welded to fix the hair. Ultrasonic heating is optimal for heating the channel wire to weld the hair. In the ultrasonic heating, as shown by arrows in FIG. 6, both sides of the groove 23 are sandwiched and vibrated by an ultrasonic horn. Instead of using ultrasonic waves, the hairs 2B can be welded by heating and sandwiching both sides of the groove 23 with a heater. Further, the bristle need not necessarily be heated and welded to the channel wire. For example, the bristles can be fixed to the channel wire with an adhesive. Since the grooved wire that fixes the hair with an adhesive does not need to be heated and melted,
It is possible to mold not only a thermoplastic plastic but also a thermosetting plastic.

The grooved wire 2C shown in FIG. 6 has a ridge 24 inside the opening of the groove 23. Channel wire 2C of this shape
Can securely hold the bristle 2B inserted into the groove 23 by the ridge 24 as shown by the chain line. In particular, when both sides of the groove 23 are sandwiched in the direction indicated by the arrow and heat-welded, there is a feature that the fused ridges 24 can enter the gaps of the bristles 2B and the bristles 2B can be more securely fixed.

Further, the groove-shaped wire 2C shown in FIG. 6 has flanges 25 protruding from both sides of the groove 23. As shown in FIG. 5, the grooved wire 2C having the flange 25 comes into contact with the core wire 2A over a wide area, and can be securely bonded and fixed. Further, the groove-shaped wire 2C having the flange 25 can be fixed to the core wire 2A at a fixed fixed pitch by being spirally wound in close contact therewith. For this reason, the hair 2B can be uniformly fixed on the surface of the core wire 2A.

The core wire 2A for fixing the channel wire 2C is made of a plastic tube 2 such as a flexible urethane tube.
It is most suitable that a metal wire 27 is inserted through 6. This core wire 2A has excellent durability. Further, the rotational torque can be efficiently transmitted in a state where the core wire 2A is bent in the U-shape. Therefore, one end or both ends can be rotated, and the whole can be integrally rotated. Further, since the surface of the wire 27 is covered with the plastic tube 26, the groove-shaped wire 2
C can be securely bonded and fixed. Also, by any chance wire 2
There is a feature that even if a part of the wire 7 is broken, it does not protrude from the surface.

The wire 27 is ideally a metal wire, but a wire in which hard plastic wires are bundled can be used in place of the metal wire. Further, a plastic rod which can be bent can be used for the core wire 2A instead of the wire 27. Since the plastic rod has a smooth surface, the grooved wire can be directly fixed to the surface without being inserted into the plastic tube.

The channel-shaped wire 2C shown in FIGS. 5 and 6 fixes the hair on the surface of the core wire in the following steps. In a state where the groove-shaped wire 2C is linearly extended, the bristles 2B are inserted into the groove 23 in a U-shaped manner. The bristle 2B pushes the U-curved portion with a thin pushing plate and inserts it into the groove 23 of the channel wire 2C. The bristles 2B are arranged on the pushing plate, and a large number of bristles 2B can be simultaneously inserted into the grooves 23 of the channel wire 2C. The push plate is pulled out, leaving the bristles 2B in the grooves 23 of the channel wire 2C.

The hairs 2B are fixed by pressing both sides of the groove 23 as indicated by arrows in FIG. 6 and welding the ultrasonic wire or heating with a heater to weld the groove-shaped wire 2C.
However, when inserting the bristle 2B, the groove 23 of the
Alternatively, the bristle 2B can be bonded to the grooved wire 2C and fixed by filling the groove 23 with the adhesive after filling the bristle 2B with the adhesive.

A long channel-shaped wire 2C with a fixed hair 2B
Is wound around a straight hard wire, for example, a straight metal pipe, and formed into a spiral shape. At this time, high-temperature boiling water or a heated liquid is flowed through the metal pipe to heat the metal pipe, and then cooled water or liquid is flowed,
The channel wire 2C can be formed into a spiral shape. The spirally shaped grooved wire 2C can be simply, easily and quickly inserted into the core wire 2A in the next step.

The wire and the core wire 2A are arranged in a straight line,
The spirally wound channel-shaped wire 2C is transferred from the wire to the core wire 2A. Thereafter, both ends of the grooved wire 2C are bonded to the core wire 2A, and the grooved wire 2C is fixed to the core wire 2A. Channel wire 2C
Is not fixed to the core wire 2A but fixed to the core wire 2A by partially bonding both ends. In this state, the grooved wire rod 2C fixed to the core wire 2A can slightly move with respect to the core wire 2A when the core wire 2A is curved and rotated, so that it can be rotated without difficulty and durability can be improved. However, the entire grooved wire can also be bonded to the core wire.

The connecting pieces 11 are fixed to both ends of the core wire 2A. The connecting pieces 11 reinforce both ends of the core wire 2A. The rotating brush 2 connects the end of the core wire 2A to a cleaning device or the like. The connecting piece 11 reinforces a portion connected to the cleaning device or the like, and reliably connects the rotating brush 2 to the cleaning device.

The rotating brush 2 does not need to have the same flexibility throughout the core wire 2A. A part of the core wire 2A may be a hard part that is not easily deformed, or a rod-shaped part that is not deformed. As shown in FIGS. 7 and 8, the rotary brush 2 in which the hard portion 2D and the bar-shaped portion 2E are provided on a part of the core wire 2A is suitable for use by bending it into a slender shape in a U-shape. This is because the middle of the rotating brush 2 does not spread widely as shown by the chain line in FIG.

The rotary brush 2 used in the state shown in FIGS. 7 and 8 has a hard portion 2D and a rod-shaped portion 2E provided at both ends of a core wire 2A. The hard portion 2D uses a hard material for the wire used for the core wire 2A, or uses a thick wire to make it difficult to deform. Further, the hard part 2D is
The wire used for the core wire 2A may be hardened by hardening it with an adhesive or the like, or may be hardened by inserting a hard wire material serving as a core into the wire. A hard portion 2D can be formed by using a plastic rod that is not easily deformed for a part of the core wire 2A.

The core wire 2A can be formed into a rod-like portion 2E using a metal shaft or pipe in part. Also,
The core wire 2A may be partially cured with an adhesive or the like to form a non-curved bar-shaped portion 2E.

In the rotary brush 2 in which both ends of the core wire 2A are hard portions 2D and rod-shaped portions 2E, the center portion of the core wire 2A is more easily curved than both end portions. For this reason, as shown in FIGS. 7 and 8, the central portion is bent in a U-shape and can be used in an elongated shape. In other words, core wire 2A that is U-shaped
There is a feature that the whole can be used in an elongated shape by making the radius of curvature of the curved portion small, and reducing the deformation of the hard portion 2D and the rod-shaped portion 2E or in a state where it is not deformed. Furthermore, the rotating brush 2 having the hard portions 2D and the rod-shaped portions 2E at both ends has a feature that a strong torsion stress acts on the hard portions 2D and the rod-shaped portions 2E, and this portion can be effectively prevented from being broken. is there. This is because, when the rotary brush 2 is driven to rotate, a portion where torsional stress is likely to concentrate is reinforced.

The hard portion 2D and the rod-shaped portion 2E provided on the core wire 2A
Is designed to have an optimum hardness according to the purpose of use of the rotating brush 2. The longer the hard part 2D or the rod-shaped part 2E is, the harder this part is, the more the rotating brush 2 can be formed into an elongated shape when bent in a U-shape. Therefore, the hardness of the hardened portions at both ends of the core wire 2A is set to an optimum value so that the rotating brush 2 can be bent into an ideal shape according to the purpose of use.

The length of the hard portion 2D or the bar portion 2E at both ends of the core wire 2A or the ratio of the hard portion 2D or the bar portion 2E to the curved portion can be variously changed according to the purpose of use of the rotary brush 2. it can. Increase the length of the hard part 2D and the rod-shaped part 2E,
In other words, as the ratio of the hard portion 2D or the bar-shaped portion 2E is increased, the rotating brush 2 becomes elongated and U-shaped when it is bent in a U-shape. Conversely, when the length of the hard portion 2D or the bar-shaped portion 2E is shortened, in other words, the ratio of the hard portion 2D or the bar-shaped portion 2E is reduced, the curved portion of the rotating brush 2 that is bent in a U-shape approaches a horseshoe shape. Therefore, the length of the hard portion 2D or the rod-shaped portion 2E or the ratio of the length to the curved portion is set to an optimum value depending on the purpose of use of the rotary brush 2 so that the rotary brush 2 can be bent into an ideal shape.
