Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventionally, a cart used in a grocery section of a supermarket, for example, has a caster 40 as shown in FIG. However, in the use of a cart (not shown) provided with such casters 40, dust such as hair and lint falling on the floor of the sales floor may cause the side surfaces 41 a of the wheels 41 of the casters 40 and the wheel holder 42. There is a problem that the wheel is difficult to rotate because it is caught between the side inner surface 42a and the wheel axle 43 of the caster, which hinders the use of the cart.

[0003] In addition, the hair, lint and the like caught in this way are often wound around the axle 43 many times, and it is not easy to remove them. Since hundreds of such carts are provided in large stores and at least dozens in small stores, all carts provided in the store are entangled on the axle 43. There were also inconveniences that required enormous effort to remove garbage.

[0004]

Therefore, there has been a demand for a caster or a caster accessory in which dust such as hair and thread debris does not get caught between the wheel and the wheel holder.

[0005]

According to the present invention, there is provided a caster cleaning brush according to the present invention.
A cylindrical body capable of surrounding the periphery of the side surface of the caster, and a brush portion having a brush body attached to at least a part of the cylindrical body so that the bristle tip projects downward from the cylindrical body, As the casters move across the floor,
The garbage on the floor can be caught while following along with it. Thus, while moving the casters on the floor, the dust existing on the floor can be captured by the brush body.

In claim 2, the diameter of the cylindrical body is made variable so that it can be commonly used for casters having different diameters. Further, in claim 3, the diameter of the cylindrical body is made variable by forming a bellows structure which can be expanded and contracted 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 can be adjusted so as to surround the caster side surface.

According to a fourth aspect of the present invention, the axial length of the cylindrical body is made variable so that a predetermined portion in the axial direction can be covered by the cylindrical body even for casters having different diameters. did. According to a fifth aspect of the present invention, in order to make the length of the cylindrical body in the axial direction variable, the cylindrical body is constituted by two inner and outer cylindrical bodies each comprising a cylindrical main body and a guide body, and these are formed in the axial direction. It is telescopic and telescopic. This allows
By adjusting the engagement position of the cylindrical body and the guide body in the axial direction, the entire length of the cylindrical body in the axial direction can be adjusted.

[0008] In claim 6, since the tubular body is made of paper, the tubular body can be manufactured at low cost and easily. Further, according to claim 7, the brush body is attached along the entire circumference of the cylindrical body, so that more dust can be captured.

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

According to the ninth aspect of the present invention, 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.

[0011]

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 a caster, 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. FIG. 5 is a front view showing a modified example of the example shown in FIG. 4, in which irregularities are provided at the tip of the brush portion, and FIG. 7 is a caster cleaning brush of this configuration example. It is a perspective view which shows the state which was loosely fitted.

As shown in FIG. 1, a cleaning brush 1 for a caster according to a first configuration example includes a tubular body 2 surrounding the periphery of the side surface of the caster, and a brush body 7 attached to the tubular 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 joined 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 joined to the inner side surface 5b of the lid 5 at one end inner surface.

[0013] The brush portion 6 is formed as follows.
Attached to. As shown in FIG. 3, first, a brush body 7 having a predetermined number of brushes (only five brushes are drawn in the figure, but actually many dozens to hundreds) is provided at a central portion 7b in the length direction. A brush body unit 7a is formed by folding it in two and bundling the portion using a wire or the like. Next, as shown in FIG. 2, the bristle tip 7c of the brush body 7 projects downward from the cylindrical body 2 into the space 9 between the inner surface 3b of the outer cylindrical body 3 and the outer surface 4a of the inner cylindrical body 4. The plurality of brush body units 7a are accommodated. At this time, it is necessary to uniformly arrange the brush bodies 7 in the space portions 9. Finally,
The inner surface 4a of the inner cylinder 4 is moved from the outer surface 3a of the outer cylinder 3 to the vicinity of the central portion 7b of each brush body unit 7a.
b, and the tip 8a thereof is bent along the inner surface 4b of the inner cylinder 4.

As the material of the tubular body 2, paper, plastic, metal, ceramics and the like are used, but paper is preferably used from the viewpoint of easiness of molding and cost. In order to prevent breakage or denting when hitting other articles, cardboard such as cardboard having a thickness of about 1 mm is most preferable.

As the material of the brush body 7, coconut fiber fibers used in a so-called "turtle scourer", natural fibers such as bamboo, cotton, hemp and the like used in a bamboo broom,
Synthetic fibers such as rayon, acrylic, nylon, and vinylon are used.

In hospitals and factories that use flammable solvents and gases, carts and the like using brushes made of synthetic fibers that generate a large amount of static electricity cannot be used 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. Also, since a certain degree of rigidity is required to sweep the floor, coconut fiber and bamboo are preferable among natural fibers, and coconut fiber is most preferable from the viewpoint of durability, workability, and the like. .

On the other hand, for carts used in food stores in supermarkets where it is not particularly necessary to prevent the generation of static electricity, brushes made of synthetic fibers such as rayon, acrylic, nylon and vinylon are preferably used. Since the amount of static electricity generated by these synthetic fibers is large, not only can the brush body itself capture dust as if entangled,
Dust can also be captured by static electricity generated in the brush body. As a result, there is an advantage that the dust capturing ability is increased.

The dimensions of the caster cleaning brush 1 may be selected so as to match the size of the caster to which the cleaning brush 1 is attached, and is not particularly limited. Normally, the diameter of the inner cylinder 4 is preferably such that a caster can be loosely fitted therein, that is, preferably about 1 cm larger than the diameter of the caster. The diameter of the outer cylinder 3 is about 1 cm larger than the diameter of the inner cylinder 4. Larger is preferred. The casters may not be loosely fitted in the inside of the inner cylindrical body 4 but may be fit in the inside of the inner cylindrical body 4 exactly. However, in the fitted state, the frictional resistance between the wheels of the casters and the inner surface 4b of the inner cylindrical body 4 increases, which hinders the smooth movement of the casters. Therefore, the loosely fitted state is preferable.

The number of the brush bodies 7 attached to the cylindrical body 2 depends on the radial unit sectional area (1c) of the space 9.
About 50 to 500 pieces per m ² ) are suitable, and 100
The most preferable 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 capturing ability is reduced, the warped bristle tips 7c can be cut and removed, and the mounting position of the set tack 8 can be shifted downward for use. The brush body 7 may be partially attached in the circumferential direction of the tubular body 2,
In order to enhance the dust capturing ability, it is preferable to attach along the entire circumference of the cylindrical body 2.

Further, as shown in FIG. 4, the brush portions 6 may be provided so that the thickness of the bristles alternates along the circumferential direction. That is, the concave portions 7d and the convex portions 7
e are alternately formed. Thus, the recess 7d
By alternately forming the projections 7e and the projections 7e, the ability to catch dust can be improved. Further, as shown in FIG. 5, a concave portion 7d 'and a convex
Even if e ′ is alternately formed in the circumferential direction, the ability to catch dust can be similarly improved. Although not shown in the figure, a concave portion 7 d ′ and a convex portion 7
e 'may be formed alternately in the radial direction. Further, the uneven portions as shown in FIGS. 4 and 5 may be used together.

In order to attach each brush body unit 7a to the cylindrical body 2, instead of the brush body unit 7a folded in two as shown in FIG. 3, a predetermined number (only ten brush units in FIG. A brush unit 7a ', which is not illustrated but is actually a hundred to several hundred brushes, and which is bundled with one end 7b' using a wire or the like, may be used as the brush unit 7a '. Further, a brush body unit having three or more folds may be used, or the 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 above-mentioned brush body unit may be mounted on 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 mounting means such as a stapler, wire, adhesive or the like. Good. Also, if the number of brushes is increased and the space portion 9 is densely filled with the brushes, the brushes are less likely to be displaced, and therefore, without using attachment means such as a tack, a stapler, a wire, an adhesive, etc. Each brush body unit may be accommodated in the space portion 9.

As shown in FIG. 7, the cleaning brush 1 for a caster constructed as described above is mounted on a caster 4 such as a cart.
When the caster 40 is rotated by rotating the caster 40 on the floor by pushing a cart or the like by loosely fitting to the floor 0, the cleaning brush 1 for a caster can catch dust on the floor while following the caster 40 so as to follow the caster 40. .

Next, a second example of the construction of the cleaning brush for casters according to the present invention is shown in FIGS. 8 is a perspective view of a cleaning brush for casters, FIGS. 9 to 11 are plan views of the brush, and FIG. 12 is a partial cross-sectional view of the brush having a lid. The cleaning brush for casters of the second configuration example is characterized in that the cylindrical body has a bellows structure that can expand and contract in the circumferential direction, and the diameter thereof is variable. Note that, in this configuration example, the first
Only parts different from the configuration example will be described.

As shown in FIGS. 8 to 10, the cleaning brush 11 for a caster 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. The brush unit 16 includes a brush unit 16.

The cylindrical body 12 comprises an outer cylindrical body 13 having eight projections 13c and an inner cylindrical body 14 having the same number of concave portions 14c arranged corresponding to the projections 13c. The brush body 17 is formed such that a bristle tip 17c of the brush body 17 projects downward from the lower end of the tubular body 12 into a space 19 between the inner surface 13b of the outer tubular body 13 and the outer surface 14a of the inner tubular body 14. Are accommodated in each of the plurality of brush body units 17a.

In order to attach each brush body unit 17a to the tubular body 12, the recess 13d of the outer surface 13a of the outer tubular body 13 is passed through the vicinity of the central portion 17b of each brush body unit 17a in which the brush bodies 17 are bundled. From the inner cylinder 14
A stud 18 reaching the projection 14d of the inner surface 14b is hit, and the tip 18a is bent along the inner surface 14b of the inner cylindrical body 14.

Cleaning brush 11 for casters of second configuration example
9 is loosely fitted on a small-diameter caster.
As shown in the figure, the bellows portions of the outer tubular body 13 and the inner tubular body 14 are contracted in the circumferential direction,
The diameter of the cylindrical body 12 is reduced so that the angle c becomes an acute angle. On the other hand, when the brush 11 is used by being loosely fitted on a caster having a large diameter, as shown in FIG.
Then, the bellows portion of the inner cylindrical body 14 is expanded in the circumferential direction, that is, the diameter of the cylindrical body 12 is enlarged so that the angle between the protrusion 13c and the concave portion 14c forms an obtuse angle.

As described above, in the second configuration example, the outer cylinder 1
The diameter of the tubular body 12 is made variable by adjusting the degree of expansion and contraction of the bellows portion of the inner tubular body 3 and 3 in the circumferential direction,
Only one cleaning brush 11 for casters with different diameters
There is an advantage that can be used in common. In order to expand and contract the bellows portions of the outer cylindrical body 13 and the inner cylindrical body 14 in the circumferential direction, it is preferable to use cardboard or the like which is thinner and thicker than the thick paper used in the first configuration example. In addition, by increasing the number of protrusions 13c and recesses 14c of the outer cylindrical body 13 and the inner cylindrical body 14, the present invention can be applied to a plurality of casters having greatly different diameters.

In the examples shown in FIGS. 9 and 10, since the wheels of the casters are caught in the concave portions 14c of the bellows, there is a problem that the wheels cannot rotate smoothly. In order to prevent such an obstacle, as shown in FIG. 11, a cylindrical tube 10 may be provided inside the inner tube 14, and the wheels of the casters may be accommodated in this tube. An overlapping portion is provided at the end in the circumferential direction so that the diameter of the tube 10 is also variable, and this portion is fastened with a rivet 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
In the case of providing a cover over which the cover 4 extends, a planar cover as used in the configuration example 1 cannot be provided. When a lid is required, for example, a paper-made and radially-expandable semi-cylindrical lid 15 is provided as shown in FIG. It is necessary to use a material whose length in the radial direction can be changed correspondingly.

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

According to the first aspect of the present invention, there is provided a cleaning brush for a caster according to the first aspect, wherein a tubular body capable of surrounding the periphery of the side surface of the caster, and a bristle tip of at least a part of the tubular body are formed downward from the tubular body. It consists of a brush part with a brush body attached so as to protrude, so that when the caster moves on the floor, it can catch dirt on the floor while following it so that it is taken along by it did.

Thus, while moving the casters on the floor, the dust existing on the floor can be captured by the brush body. For example, hair and thread falling on the floor such as a grocery store in a supermarket can be obtained. Debris such as debris can be prevented from being caught between the side surfaces of the wheels of the casters and the inner surface of the side portions of the wheel holder and entangled in the axle, so that the cleanliness required for the grocery store is not impaired. In addition, it is possible to prevent the rotation of the caster from being hindered by the pinching and entanglement of such hair and lint. In addition, there is an advantage that a great deal of effort is required to remove dusts caught on the axles of the casters.

It is telescopic and telescopic. A simple nesting type engagement method is adopted for the cylindrical body, and the axial overlapping length between the cylindrical body and the guide body can be reduced only by adjusting the axial engagement position between the cylindrical body and the guide body. As a result, the entire length of the cylindrical body in the axial direction can be easily adjusted.

In the sixth aspect, paper is used as the material of the cylindrical body, so that the cylindrical body can be manufactured at low cost and easily. In the seventh aspect, the brush body is attached along the entire circumference of the cylindrical body, so that the area of the brush portion in the radial direction can be increased, so that more dust can be captured.

In the eighth aspect, the brush body is made of coconut fiber which generates a small amount of static electricity, so that the static electricity generated in the brush body during movement of the cart can be reduced.
For example, in a hospital or a factory using a flammable solvent or gas, it is suitably used to prevent ignition due to static electricity.

According to the ninth aspect, since the brush body is made of synthetic fiber, the dust can be captured not only by the brush body itself but also by the static electricity generated in the brush body. It becomes possible.
