BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, a caster of a cart used in a grocery section of a supermarket, a caster of a cart carrying an infusion device attached to a patient in a hospital, a caster of a chair used in an office, etc. The present invention relates to a cleaning brush for casters, which is attached to catch dust such as hair and lint on the floor surface and prevent the dust from getting caught on the caster shaft.

[0002]

2. Description of the Related Art Conventionally, for example, a cart used in a grocery section of a supermarket has a caster 40 as shown in FIG. However, when a cart (not shown) equipped with such casters 40 is used, dust such as hair and lint that has fallen on the floor of the sales floor is generated by the side surface 41 a of the wheels 41 of the casters 40 and the wheel holder 42. There is an inconvenience that it is sandwiched between the inner surface 42a of the side portion and entangled with the axle 43 of the caster, which makes it difficult for the caster to rotate and hinders the use of the cart.

Further, the hair, thread waste, etc. thus sandwiched are often difficult to remove because they are often wound around the axle 43 in multiple layers. Large carts have hundreds of such carts, and even small shops have at least tens of carts, so all carts in the store are entangled in the axle 43. There was also the inconvenience that it took a lot of effort to remove the dust.

[0004]

Therefore, there has been a demand for casters or caster accessories in which dust such as hair and lint is not caught between the wheel and the wheel holder.

[0005]

In order to solve the above-mentioned problems, the cleaning brush for casters according to the present invention is defined by claim 1.
In, consisting of a tubular body capable of surrounding the periphery of the side surface of the caster, and a brush portion provided with a brush body attached to at least a part of the tubular body so that the bristle tips project downward from the tubular body, When the casters move on the floor,
It catches dust on the floor while following along with it, and the diameter of the cylindrical body is variable.
To collect.

As a result, the casters are moved on the floor surface.
While moving it, catch dust on the floor with a brush body
Can be caught. Furthermore, by making the diameter of the cylindrical body variable, it is possible to commonly use casters having different diameters. Further, in claim 2 , the diameter is made variable by forming the tubular body into a bellows structure capable of expanding and contracting in the circumferential direction. Thus, by adjusting the degree of expansion and contraction of the bellows portion in the circumferential direction, the diameter of the tubular body attached to the caster side surface can be adjusted so as to surround the side surface of the caster.

According to the third aspect of the present invention , the axial length of the tubular body is made variable, so that even for casters having different diameters, a predetermined portion in the axial direction can be covered with the tubular body. did. Further, according to claim 4 , in order to make the axial length of the tubular body variable, the tubular body is composed of two inner and outer tubular bodies composed of a tubular body and a guide body, and these are axially arranged. It is a telescopic type that can be expanded and contracted. This allows
By adjusting the engagement position between the tubular body and the guide body in the axial direction, the overall length of the tubular body in the axial direction can be adjusted.

[0008] By the claim 5 the tubular body was made of paper, and a cheap and easily manufactured tubular body. Further, according to the sixth aspect , since the brush body is attached along the entire circumference of the cylindrical body, more dust can be captured.

According to the seventh aspect of the present invention , the brush body is made of coconut fiber, so that static electricity generated in the brush body can be reduced.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the accompanying drawings. First, FIGS. 1 to 7 show a first configuration example of the cleaning brush for casters according to the present invention.
1 is a perspective view of a cleaning brush for casters, FIG. 2 is a sectional view taken along line AA of FIG. 1, FIGS. 3 and 6 are front views of a brush body unit in which a plurality of brush bodies are bundled, and FIG. 5 is a cross-sectional view taken along line BB, FIG. 5 is a front view showing an example of a modification of the example shown in FIG. 4 in which the tip portion of the brush portion is provided with irregularities, and FIG. 7 is a caster cleaning brush for this configuration example It is a perspective view showing the state where it was loosely fitted in.

As shown in FIG. 1, a caster cleaning brush 1 according to the first configuration example comprises a cylindrical body 2 surrounding the side surface of the caster, and a brush body 7 attached to the cylindrical body 2. The brush unit 6 is provided. As shown in FIG.
The tubular body 2 includes an outer tubular body 3, an inner tubular body 4 and a lid 5. The outer cylindrical body 3 is bonded to the outer side surface 5a of the lid 5 at one end outer surface with an adhesive or the like, and the inner cylindrical body 4 is similarly bonded to the inner side surface 5b of the lid 5 at one end inner surface.

The brush portion 6 is formed by the tubular body 2 as follows.
Attached to. As shown in FIG. 3, first, a brush body 7 in which a predetermined number (only five are drawn in the drawing, but is actually several tens to hundreds) is arranged at a central portion 7b in the longitudinal direction. The brush body unit 7a is formed by folding it in two and bundling the portions with a wire or the like. Next, as shown in FIG. 2, the bristle tips 7c of the brush body 7 project downward from the tubular body 2 in the space portion 9 between the inner surface 3b of the outer tubular body 3 and the outer surface 4a of the inner tubular body 4. A plurality of brush body units 7a are accommodated as described above. At this time, it is necessary to uniformly arrange the brush body 7 in the space portion 9. Finally,
The outer surface 3a of the outer cylinder 3 to the inner surface 4 of the inner cylinder 4 are passed through in the vicinity of the central portion 7b of each brush body unit 7a.
The retaining stud 8 reaching b is hit and the tip 8a thereof is bent along the inner surface 4b of the inner cylindrical body 4.

As the material of the tubular body 2, paper, plastic, metal, ceramics, etc. are used, but paper is preferably used from the viewpoint of ease of molding, cost and the like. A cardboard such as a cardboard having a thickness of about 1 mm is most preferable so as not to be damaged or dented when hitting another article.

The material of the brush body 7 includes palm fiber such as that used in so-called "Kameko Scourer", natural fiber such as bamboo, cotton and linen such as used in bamboo broom, and
Synthetic fibers such as rayon, acrylic, nylon and vinylon are used.

In hospitals, factories and the like which use flammable solvents and gases, it is not possible to use a cart or the like in which a brush is made of a synthetic fiber which generates a large amount of static electricity in order to prevent ignition due to static electricity. Therefore, in such a place, a brush body using a natural fiber that generates a small amount of static electricity is preferably used. Further, since it requires a certain degree of rigidity to sweep the floor surface, palm fruit fibers and bamboo are preferred among the natural fibers, and palm fruit fibers are most preferred from the viewpoints of durability and processability. .

On the other hand, a brush body made of synthetic fiber such as rayon, acrylic, nylon or vinylon is preferably used for a cart used in a grocery section of a supermarket where it is not particularly necessary to prevent the generation of static electricity. Since the amount of static electricity generated by these synthetic fibers is large, not only is the brush body itself tangled to trap dust,
Dust can also be captured by the static electricity generated on the brush body. As a result, there is an advantage that the dust capturing capability is increased.

The size of the caster cleaning brush 1 may be selected so as to fit the size of the caster to which it is attached, and is not particularly limited. In general, it is preferable that the diameter of the inner cylindrical body 4 is larger than the diameter of the caster by about 1 cm, and the diameter of the outer cylindrical body 3 is about 1 cm larger than the diameter of the inner cylindrical body 4. It is preferably large. It should be noted that the casters may not be loosely fitted inside the inner cylindrical body 4 but may be fitted tightly inside this. However, in the fitted state, the frictional resistance between the wheels of the caster and the inner surface 4b of the inner cylindrical body 4 increases and the smooth movement of the caster is hindered. Therefore, the loosely fitted state is preferable.

The number of brush bodies 7 attached to the cylindrical body 2 is the unit cross-sectional area (1c) in the radial direction of the space portion 9.
About 50 to 500 pieces are suitable per m ² ) and 100
Most preferably, the number is about 200. The length of the portion of the brush body 7 protruding from the lower end of the tubular body 2 is preferably about 1 to 2 cm. When the bristle tips 7c of the brush body 7 are warped and the dust trapping ability is reduced, it is also possible to cut and remove the warped bristle tips 7c and shift the mounting position by the locking tacks 8 downward to use. The brush body 7 may be partially attached in the circumferential direction of the tubular body 2,
In order to enhance the dust trapping ability, it is preferable to mount the tubular body 2 along the entire circumference thereof.

Further, as shown in FIG. 4, the brush portions 6 may be provided such that the bristles have different thicknesses along the circumferential direction. That is, the concave portion 7d and the convex portion 7 are formed on the outer peripheral surface thereof.
e are formed alternately. Thus, the recess 7d
By alternately forming the convex portions 7e and the convex portions 7e, the dust capturing ability can be improved. Further, as shown in FIG. 5, the concave portion 7d ′ and the convex portion 7 are provided in a portion of the brush portion 6 which is in contact with the floor surface.
Even if e'is formed alternately in the circumferential direction, the dust capturing ability can be similarly improved. Although not shown in the drawing, the concave portion 7d ′ and the convex portion 7 are provided in the portion of the brush portion 6 that contacts the floor surface.
The e ′ may be formed alternately in the radial direction. Moreover, you may use together the uneven | corrugated part as shown in FIG. 4 and FIG.

To attach each brush body unit 7a to the cylindrical body 2, the brush body unit 7a folded in two as shown in FIG. 3 is not used, but a predetermined number (only 10 in the figure) as shown in FIG. The brush body 7 may be used as a brush body unit 7a ', which is formed by bundling one end side 7b' of the brush body 7 in which hundreds to several hundreds are arranged (not shown). Further, a brush body unit having three or more folds may be used, or a brush body unit 7a ′ shown in FIG. 6 and a brush body unit having two or more folds may be used in any combination.

Further, the brush unit as described above may be attached to at least one of the inner surface 3b of the outer cylindrical body 3 and the outer surface 4a of the inner cylindrical body 4 by using a mounting means such as a stapler, a wire or an adhesive. Good. Further, if the number of brush bodies is increased and the space portion 9 is filled with this at a high density, the brush bodies are less likely to be displaced, and therefore, without using attachment means such as a tack, a stapler, a wire, or an adhesive. Each brush body unit may be housed in the space portion 9.

As shown in FIG. 7, the caster cleaning brush 1 configured as described above is used as a caster 4 for a cart or the like.
By loosely fitting into 0, when the caster 40 is rotationally moved on the floor surface by pushing a cart or the like, the dust on the floor surface can be captured while following the caster cleaning brush 1 as if it were entrained by the caster 40. .

Next, FIGS. 8 to 12 show a second structural example of the cleaning brush for casters according to the present invention. 8 is a perspective view of the cleaning brush for casters, FIGS. 9 to 11 are plan views of the brush, and FIG. 12 is a partial sectional view of the brush having a lid. The caster cleaning brush of the second configuration example is characterized in that the tubular body has a bellows structure that is capable of expanding and contracting in the circumferential direction, and the diameter thereof is variable. In this configuration example, the first
Only parts different from the configuration example will be described.

As shown in FIGS. 8 to 10, the caster cleaning brush 11 according to the second configuration example has a cylindrical body 12 surrounding the periphery of the side surface of the caster and a brush body attached to the cylindrical body 12. A brush unit 16 composed of 17 is provided.

The tubular body 12 comprises an outer tubular body 13 having eight projections 13c and an inner tubular body 14 having the same number of recesses 14c arranged so as to correspond to the projections 13c. The brush body 17 has a bristle tip 17c of the brush body 17 protruding downward from a lower end of the tubular body 12 in a space portion 19 between the inner surface 13b of the outer tubular body 13 and the outer surface 14a of the inner tubular body 14. , Each of the plurality of brush body units 17a is housed.

In order to attach each brush body unit 17a to the cylindrical body 12, the brush body 17 is passed through the brush body units 17a in the vicinity of the central portion 17b, and the recess 13d of the outer surface 13a of the outer cylinder body 13 is inserted. To inner cylinder 14
The stopper stud 18 reaching the protrusion 14d on the inner surface 14b is hit and the tip 18a thereof is bent along the inner surface 14b of the inner cylindrical body 14.

The diameter of the cylindrical body 12 is reduced so that the angle of c forms an acute angle. On the other hand, when the brush 11 is used by loosely fitting it in a caster having a large diameter, as shown in FIG.
Then, the bellows portion of the inner tubular body 14 is widened in the circumferential direction, that is, the diameter of the tubular body 12 is enlarged so that the angle between the projecting portion 13c and the concave portion 14c forms an obtuse angle.

As described above, in the second configuration example, the outer cylindrical body 1
3, the diameter of the tubular body 12 is made variable by adjusting the degree of expansion and contraction in the circumferential direction of the bellows portion of the inner tubular body 14.
Only one cleaning brush for casters with different diameters 11
Have the advantage that they can be used in common. In order to expand and contract the bellows portions of the outer tubular body 13 and the inner tubular body 14 in the circumferential direction, it is preferable to use cardboard, which is thinner and more flexible than the cardboard used in the first configuration example. Further, by increasing the number of the protruding portions 13c and the concave portions 14c of the outer tubular body 13 and the inner tubular body 14, it is possible to apply to a plurality of casters having greatly different diameters.

In the example shown in FIGS. 9 and 10, the wheel portion of the caster is caught in the bellows recess 14c, which causes a problem that the wheel cannot rotate smoothly. In order to prevent such trouble, as shown in FIG. 11, a cylindrical cylinder 10 may be provided inside the inner cylinder 14 and the wheels of the casters may be housed in this cylinder. The tube 10 is also provided with an overlapping portion at the end in the circumferential direction so that the diameter can be varied, and this portion is fastened with a locking tack 10a.

In this configuration example, since the diameters of the outer cylinder 13 and the inner cylinder 14 are variable, the outer cylinder 13 and the inner cylinder 1
When the lid for hanging 4 is provided, it is not possible to provide the planar lid as used in the configuration example 1. When a lid is required, for example, as shown in FIG. 12, a capsular lid 15 made of paper and expandable and contractible in the radial direction is provided to change the diameters of the outer tubular body 13 and the inner tubular body 14. Correspondingly, it is necessary to use a material whose radial length can be changed.

Next, FIGS. 13 and 14 show a third structural example of the caster cleaning brush according to the present invention. FIG. 13 is a cross-sectional view of the cleaning brush for casters, and FIG. 14 is a perspective view showing a tubular guide body.

[0048]

The cleaning brush for casters according to the present invention is characterized in that, in claim 1, a tubular body which can surround a side surface of the caster and at least a part of the tubular body has a bristle tip downward from the tubular body. It consists of a brush portion provided with a brush body attached so as to project, and when the caster moves on the floor surface, it catches the dust on the floor surface while following along so as to be accompanied by it. The diameter of the cylindrical body is variable
It was

With this, while the casters are moved on the floor surface, dust existing on the floor surface can be captured by the brush body. For example, hair and yarn falling on the floor surface in a grocery section of a supermarket or the like. It is possible to prevent dust such as dust from being caught between the side surface of the wheel of the caster and the inner surface of the side portion of the wheel holder and being entangled in the axle, and as a result, do not impair the cleanliness necessary for the grocery section, and It is possible to prevent the hindrance of the rotation of the caster due to such pinching and entanglement of hair and thread waste. Further, there is an advantage that a great deal of labor for removing dust trapped on the axle of the caster is unnecessary.

In the grocery section of a supermarket, the floor is regularly cleaned by a cleaner, but the floor is also cleaned when the customer pushes the cart to move the floor. There is also an advantage that it is always kept clean.

Further, by making the diameter of the cylindrical body variable, it is possible to use only one cleaning brush for casters in common for casters having different diameters, so that a variety of casters having different diameters can be prepared. There is no need to do it.

According to the second aspect , the diameter of the tubular body is made variable by providing the tubular body with a bellows structure capable of expanding and contracting in the circumferential direction. The degree of expansion and contraction of the bellows portion in the circumferential direction can be easily adjusted only by adopting a simple structure called a bellows structure for the tubular body. As a result, the diameter of the cylindrical body attached to the caster can be easily adjusted so that the side surface of the caster can be surrounded.

According to the third aspect of the present invention , the axial length of the tubular body is made variable so that a predetermined axial portion of the casters having different diameters can be covered with the tubular body.

[0054] In claim 4, the axial length of the cylindrical body to be variable, in the axial direction together constituting a inner and outer two cylindrical body comprising a cylindrical body from the cylindrical body and a guide body It is a telescopic type that can be expanded and contracted. Adopting a simple nesting type engagement method for the tubular body, the axial overlap length of the tubular body and the guide body can be adjusted simply by adjusting the axial engagement position between the tubular body and the guide body. As a result, the overall length of the tubular body in the axial direction can be easily adjusted.

According to the fifth aspect of the invention , paper is used as the material of the tubular body, so that the tubular body can be manufactured inexpensively and easily. Further, according to the sixth aspect , since the brush body is attached along the entire circumference of the tubular body, the area of the brush portion in the radial direction can be increased, and thus more dust can be captured.

According to the seventh aspect of the present invention , the brush body is made of coconut fruit fibers that generate a small amount of static electricity, so that the static electricity generated on the brush body during the movement of the cart can be reduced.
For example, in hospitals and factories that use flammable solvents and gases, it is preferably used to prevent ignition due to static electricity.

In the eighth aspect , since the brush body is made of synthetic fiber, dust can be captured not only by the brush body itself but also by static electricity generated in the brush body, so that the dust capturing ability can be increased. It will be possible.
