Description

  The present invention relates to a brush used in general cleaning and a cleaning tool including the brush.

  2. Description of the Related Art Conventionally, as a brush used for cleaning an object, for example, a foot-washing mat configured by implanting a large number of flexible hairs on a base is known (Patent Document 1).

  In such a foot washing mat, when a foot is placed on and rubbed to wash the foot, the hair touches the sole or a flexible hair enters between the toes. While the skin between the toes and the toes is stimulated with moderate strength by the hair, dirt and dirt attached to the skin can be scraped off and removed by the hair.

JP 2003-325373 A

  However, in the above conventional foot washing mat, since the hair portion is soft and flexible, dirt and dirt that can be removed relatively easily can be removed sufficiently. There is room for improvement in that it cannot sufficiently remove dirt and foreign matter that cannot be removed easily, such as hard keratin. Such a point is not limited to a foot washing mat, and is common to brushes used for general washing such as a brush for washing human fingers and body, a brush for washing cooking utensils, a brush for washing floors, tiles, and the like. .

  Then, this invention is made | formed in view of the said point, and makes it a subject to provide the cleaning tool provided with the brush which can fully remove a stain | pollution | contamination, a foreign material, etc., and this brush.

  The brush according to the present invention has been made to solve the above-described problems, and includes a base portion and a plurality of flexible bristle portions erected on the base portion, and a base end portion of the bristle portion is provided. A polishing part having polishing properties is provided at least at the tip part.

  In the brush having such a configuration, the bristle portion standing on the base portion is provided with a polishing portion having polishing properties at least at the tip portion excluding the base end portion. When the object to be cleaned is rubbed against the brush to clean the back, cooking utensils, floor, etc., or the brush is rubbed against the object to be cleaned, the hair part mainly has the base end part where the polishing part is not provided. It is possible to bend and adjust well to the shape of the object to be cleaned, the polishing part on the tip side firmly contacts the object to be cleaned, and to remove the dirt and foreign matter so as to sharpen the contact part with the polishing part. Therefore, for example, even dirt and foreign matter that cannot be easily removed, such as hard horny material on the soles of the feet and burnt dirt on cooking utensils, or dirt on the floor and tiles, can be sufficiently removed.

  In the brush according to the present invention, it is preferable that the polishing portion is a polishing layer formed by applying an abrasive to the surface of the bristle portion.

  According to such a configuration, it is possible to grind off dirt and foreign matter so as to sharpen the portion in contact with the object to be cleaned by the polishing layer, and improve the polishing performance.

  Moreover, in the brush which concerns on this invention, it is preferable that the said hair part comprises the taper shape which becomes thin toward the front-end | tip part side, and the space | interval space | interval of adjacent hair parts is 3-10 mm.

  According to this configuration, when the object to be cleaned is rubbed against the brush (or the brush against the object to be cleaned), a large number of bristles have a spacing of 3 to 10 mm, and each of them flexes mainly at the base end. Since it conforms to the shape of the object to be cleaned as a whole, the hair part evenly contacts the area that is rubbing against the brush to be cleaned, and there is a narrow part (for example, between toes or a groove of a cooking appliance) on the object to be cleaned. In some cases, a tapered tip portion (provided with a polishing portion) enters the narrow portion. Therefore, it is possible to easily and effectively grind the dirt or foreign matter to be cleaned.

  Moreover, in the brush which concerns on this invention, it is preferable that the length of the said hair part is 5-30 mm, and the space | interval space | interval of adjacent hair parts is 3-10 mm.

  According to such a configuration, when the object to be cleaned is rubbed against the brush (or the brush against the object to be cleaned), a large number of hairs have a spacing of 3 to 10 mm, and each has a length of 5 to 30 mm. Because it flexibly bends well and adapts well to the shape of the object to be cleaned, the hair evenly contacts the area that is rubbing against the brush to be cleaned, so that dirt and foreign matter etc. on the object to be cleaned can be easily and effectively scraped off. Can be polished. Furthermore, in the region where the object to be cleaned and the brush are rubbed with each other, the hairs rub against each other during the cleaning. Therefore, foaming of the detergent can be promoted when cleaning with a detergent such as soap.

  Moreover, the cleaning tool which concerns on this invention is equipped with the brush in any one of the above-mentioned, and the detergent which has antimicrobial property, It is characterized by the above-mentioned.

  According to the cleaning tool having such a configuration, the brush can remove and polish dirt and foreign matter to be cleaned, and can promote the removal of dirt and the like by the surface-active action of the detergent. Due to the antibacterial action of the detergent, it is possible to suppress the growth of bacteria after cleaning in the polished part to be cleaned. Furthermore, since the foaming of the detergent at the time of washing | cleaning can be improved, the surface active action of a detergent can be heightened effectively and the washing | cleaning effect can be improved. Therefore, for example, even dirt and foreign matters that cannot be easily removed, such as hard keratin on the sole of the foot, burnt dirt on cooking utensils, or dirt on the floor or tiles, can be removed sufficiently.

  As described above, according to the brush according to the present invention and the cleaning tool including the brush, since at least the distal end portion of the bristle portion excluding the proximal end portion is provided with a polishing portion having polishing properties, When the object to be cleaned is rubbed against the brush to clean the object to be cleaned (or the brush is rubbed against the object to be cleaned), the bristle portion of the brush will bend and become familiar with the surface shape of the object to be cleaned. By sharpening, it is possible to sufficiently remove dirt and foreign matters.

  Hereinafter, an embodiment of a brush according to the present invention will be described with reference to the drawings.

  FIG. 1 shows a brush 1 according to this embodiment. The brush 1 is used for cleaning a human sole (such as keratin and dirt), and is used by rubbing the sole. Specifically, the brush 1 includes a base portion 2 and a plurality of flexible hair portions 3 standing on the base portion 2. The brush 1 (that is, the base 2 and the bristles 3) is a material having flexibility (or elasticity), and is a resin molded body made of a synthetic resin (for example, polyvinyl chloride resin, vinyl chloride resin, (Styrenic elastomer resin) is integrally molded.

  The base 2 according to the present embodiment is configured in a mat shape including a flat plate-like main body portion 21 with flat front and back surfaces and an edge portion 22 provided on the periphery of the main body portion 21. Here, the edge 22 is configured such that the inner end protrudes toward the 2a side and the outer end protrudes toward the 2b side. In addition, a large number of bristle portions 3 to be described later are erected on the main body surface 2a, and a number of suction cups 23 are provided on the back surface 2b of the main body for adsorbing and fixing the main body 21 to a floor, an inclined surface, a wall or the like. ing. In addition, these many suction cups 23 are spaced apart from each other so as to cover the entire surface of the back surface 2b of the main body, and in particular, the central region corresponding to the foot arch is more than the other regions corresponding to the foot tips and the heels. Are also arranged with a spacing interval so as to be dense. The base 2 is a flexible (or elastic) material, and is a resin molded body made of synthetic resin (for example, polyvinyl chloride resin, vinyl chloride resin, styrene elastomer resin).

  The bristle portion 3 according to the present embodiment has a linear bar shape, and a base end portion 31 in the longitudinal direction is fixed to the base portion 2 and is erected with respect to the base portion 2. Specifically, the bristle portion 3 has a tapered shape (tapered and substantially circular in plan view, that is, a conical shape) that gradually decreases in diameter from the proximal end portion 31 toward the distal end side 32a. As shown in FIG. 2A, 32 is configured in a front view cup shape (hereinafter referred to as a cup shape) having a flat upper surface and a substantially circular shape in plan view, and a diameter increasing toward the top. Further, the bristles 3 have a length of 20 mm, a resin hardness of 40 degrees (JIS-K6253 durometer type A (Shore A) hardness), a base end side 31a diameter of 2.8 mm, and a tip end side 32a. The diameter is 1.7 mm, and the diameter of the upper surface of the distal end portion 32 is 3.5 mm (that is, the diameter of the upper surface of the distal end portion 32 is larger than the diameter of the proximal end portion 31a). In addition, the diameter of the base end part side 31a in the hair part 3 provided in the front side X of the main-body-part surface 2a of the base 2 corresponding to a toe among many hairs 3, and the diameter of the front end part 32a Is slightly larger than each diameter in the bristle portion 3 provided on the rear side Y corresponding to the heel of the foot. For example, the diameter of the proximal end side 31a of the hair portion 3 on the front side X is 3.0 mm, and the diameter of the distal end side 32a is 1.9 mm.

  Further, a plurality of bristles 3 are erected apart from each other over the entire surface 2a of the main body 2 of the base 2, and the spacing between adjacent bristles 3 (the front and rear (XY) direction of the base 2 is orthogonal to that). (Separation interval in the left-right direction) is 6 mm. The bristle 3 is a flexible (or elastic) material, and is a resin molded body made of a synthetic resin (for example, polyvinyl chloride resin, vinyl chloride resin, styrene elastomer resin).

  Further, the bristle portion 3 is configured by providing a polishing portion 33 having a polishing property at least at the distal end portion 32 except the base end portion 31 in the longitudinal direction. Specifically, the polishing portion 33 is provided at least at the distal end portion 32 in the region closer to the distal end than the proximal end portion 31 of the bristles 3. In the present embodiment, the polishing portion 33 is provided from the distal end portion 32 of the bristle portion 3 to the central portion in the longitudinal direction, and specifically, extends from the distal end portion 32 to a length of about 5 mm along the longitudinal direction. Is provided. In addition, the grinding | polishing part 33 of the bristle part 3 is simplified and shown using hatching in FIG. 2 (a), (b), and illustration is abbreviate | omitted in another figure.

  The polishing unit 33 according to the present embodiment includes a polishing layer formed by applying an abrasive to the surface of the bristle portion 3. The abrasive is made of, for example, one or more of silicon carbide, tourmaline, alumina, and glass, and preferably made of alumina. The particle size of the abrasive is 1-100 μm, preferably 3-60 μm.

  Here, the shaping | molding of the brush 1 which concerns on this embodiment is demonstrated. The brush 1 having the above-described configuration injects a molten resin (synthetic resin) into a predetermined mold through an injection port (corresponding to the molten resin injection port mark R in FIG. 1A) by injection molding (injection molding). The entire structure is integrally formed except for the polishing portion 33. A thin film-like polishing layer is applied to the surface of the bristle portion 3 by applying an abrasive to the tip end side 32a of the bristle portion 3 of the molded resin body in this way via a urethane or acrylic adhesive. A polishing portion is formed. Here, the coating is performed by spraying a coating material in which the blending ratio of the adhesive and the abrasive is 3: 7 on the tip end side 32a of the hair 3 by spraying or the like, or a container in which the coating material is put. The tip part side 32a of the bristle part 3 is soaked.

  The brush 1 according to the present embodiment having the above-described configuration is used by adhering and fixing the back surface 2b of the main body part to a floor or the like to rub the sole, and rubbing the sole against the surface 2a of the main body part. . If it demonstrates in detail, the brush 1 will adsorb | suck the suction cup 23 of the main-body part back surface 2b to a floor etc., and will fix the brush 1. FIG. Then, the toes are placed on the bristles 3 on the front side X having a relatively large diameter with respect to the bristles 3 on the surface 2a of the main body, and the heels of the feet are put on the bristles 3 on the back side Y. Then, the foot is moved back and forth and the sole is rubbed against the hair 3. When the sole is rubbed, the entire hair portion 3 mainly bends at the base end portion 31 where the polishing portion 33 is not provided as shown in FIG. 2B, for example. The brush 1 can be used with both feet or with only one of the right foot or the left foot.

  In addition, the brush 1 according to the present embodiment is used alone for cleaning the soles as described above. In addition, the cleaning tool together with the antibacterial detergent (that is, the cleaning tool according to the present embodiment is a brush) 1 and a detergent having antibacterial properties). The detergent is, for example, soap or synthetic detergent, and in this embodiment, the soap has antibacterial properties. When the soap is used, the soap is wet with water against the tip side 32a of the bristles 3 of the main body surface 2a in a state where the brush 1 is adsorbed and fixed to the floor or the like by the suction cup 23 on the main body back surface 2b. Rub. When the soap is rubbed, the soap rubs against the polishing part 33 and foams, and the foam adheres to the brush 1 (base part 2 and hair part 3). Then, with the soap bubbles adhering to the brush 1 (base 2 and hair 3), the foot is placed on the brush 1 and the sole is rubbed against the hair 3.

  As described above, according to the brush 1 according to the present embodiment, the bristles 3 standing on the base 2 are provided with the polishing portion 33 having polishing properties at least at the tip 32 excluding the base end 31. Therefore, when the sole is rubbed against the brush 1 or the brush 1 is rubbed against the sole in order to clean the sole, the bristle portion 3 has a base end portion 31 where the polishing portion 33 is not provided. As a result, the entire body bends and conforms well to the shape of the sole, and the polishing part 33 on the tip end side 32a firmly contacts the sole, and the polishing part 33 scrapes off dirt and foreign matter so as to sharpen the contact part. Can be polished. Therefore, even if there is a hard keratin on the sole, it can be sufficiently removed. Furthermore, since the brush 1 is a resin molded body, it can be used in a sanitary manner due to water repellency, because the surface of the brush 1 after cleaning is less likely to be contaminated.

  Further, since the polishing portion 33 is a polishing layer formed by applying an abrasive to the surface of the bristle portion 3, so as to sharpen the portion in contact with the sole by the polishing layer, keratin, dirt, etc. Can be scraped off and polished, so that the polishing property can be improved.

  Moreover, since the grinding | polishing part 33 consists of microparticles | fine-particles of an alumina with a particle size of 3-60 micrometers, for example, when grinding a sole, a feeling of touch is good and can polish a sole gently and smoothly.

  Further, the bristle portion 3 has a tapered shape that becomes narrower toward the tip end side 32a, and the spacing between adjacent bristle portions 3 is densely provided at 6 mm. When the brush 1 is rubbed against the sole, a large number of hairs 3 have a spacing of 6 mm, and each of them is mainly bent at the base end portion 31 and conforms to the shape of the sole as a whole. The bristle portion 3 uniformly contacts the area rubbing against the brush 1, and the tapered tip 32 (the polishing portion 33 is provided) enters the narrow part of the sole (for example, between the toes). . Therefore, it is possible to easily and effectively grind off the dirt on the soles and foreign matters.

  Further, since the tip portion 32 of the bristle portion 3 has a cup shape, the abrasive applied in accordance with the shape of the tip portion side 32 a is held by the tip portion 32. That is, the bristles 3 are formed with a polishing material holding portion that holds the polishing material constituting the polishing portion 33 (polishing layer) against the bristles 3, so that the polishing material is held by the bristles 3. The peeling from the bristles 3 is suppressed (prevented), and the durability of the abrasive can be improved. Moreover, since the cup-shaped upper surface periphery in the front-end | tip part 32 is formed sharply, the polishability by the grinding | polishing part 33 can be improved.

  Moreover, since the length of the hair part 3 is 20 mm and the spacing distance between the adjacent hair parts 3 is 6 mm, when the sole is rubbed against the brush 1 (or the brush 1 on the sole), many The bristles 3 have a spacing of 6 mm, each having a length of 20 mm, flexing flexibly and adapting well to the shape of the sole, so that the bristles are in the region of rubbing with the brush 1 on the sole As a result of the contact of 3 evenly, dirt and foreign matter on the sole can be scraped off and polished easily and effectively. Furthermore, in the region where the sole and the brush 1 rub against each other, the hairs 3 rub against each other during cleaning. Therefore, when washing is performed using a detergent such as soap, foaming of the detergent can be promoted. it can.

  Further, the bristles 3 have a tapered shape that becomes thinner toward the distal end side 32a, the diameter of the proximal end side 31a is 2.8 mm (3.0 mm), and the diameter of the distal end side 32a is 1.7 mm (1.9 mm). Therefore, when the sole is rubbed against the brush 1 (or the brush 1 is rubbed against the sole), each of the hairs 3 flexes mainly the base end portion 31 as a whole, and a large number of the hairs 3 as a whole. Familiar with the surface shape of the sole, and the polishing part 33 on the tip side 32a of each bristle part 3 is firmly in contact with the surface of the sole. As a result, it easily and effectively removes dirt and foreign matter from the sole and polishes it. can do.

  Moreover, since the hair part 3 is a resin molding and the resin hardness is 40 degree | times, the flexibility (or elasticity) of the hair part 3 can be improved, and a hair part is wash | cleaned at the time of a sole wash | cleaning. When the sole is rubbed against the hair 3, the hair 3 can be flexed extremely flexibly.

  Moreover, the diameter of the base end part side 31a in the hair part 3 provided in the front side X of the main-body-part surface 2a of the base 2 corresponding to a toe among many hairs 3, and the diameter of the front-end | tip part side 32a Are slightly larger than the diameters of the bristles 3 provided on the back side Y corresponding to the toes of the foot, so that the bristles 3 on the front side X enter the gaps between the toes moderately. When contacting and rubbing the sole against the brush 1, dirt and keratin between the toes can be easily and effectively scraped and polished.

  Further, since the suction cup 23 is provided on the back surface 2 b of the main body portion of the brush 1, the brush 1 can be adsorbed and fixed to the floor or the like, and the sole can be easily rubbed against the brush 1.

  The many suction cups 23 are arranged so as to be separated from each other so as to cover the entire surface of the back surface 2b of the main body, and in particular, the central region corresponding to the foot arch is more than the other regions corresponding to the foottips and the heels. Since they are arranged so as to be densely spaced, for example, even when the sole is rubbed against the brush 1, the central portion of the brush 1 in the front-rear direction is adsorbed and fixed without shaking. The foot 1 can be held and rubbed against the brush 1 smoothly.

  Moreover, since the edge part 22 is provided in the peripheral part in the main-body-part surface 2a of the base 2, when using detergent, water, etc. at the time of washing | cleaning of a sole, these can be stored in the main-body part surface 2a. It can promote the foaming of the detergent.

  In addition, since the cleaning tool is configured to include the brush 1 and antibacterial soap (detergent), the brush 1 can be used to scrape off dirt on the soles of the feet and foreign matter, and polish the soap. It is possible to promote the removal of dirt and the like by the surface active action of the soap, and the antibacterial action of the soap suppresses the growth of bacteria (for example, ringworm that causes athlete's foot) after washing in the polished part of the sole. be able to. Furthermore, since the foaming of the detergent at the time of washing | cleaning can be improved, the surface active effect | action of soap can be heightened effectively and the washing | cleaning effect can be improved. Accordingly, even the hard keratin on the sole can be removed sufficiently, and even after the removal, bacterial growth on the sole can be suppressed and a clean feeling can be maintained.

  In addition, the brush 1 of this invention is not limited to the said embodiment, Of course, a various change can be added in the range which does not deviate from the summary of this invention.

  In the present embodiment, the brush 1 has been described as having a mat shape so as to clean the soles. However, the present invention is not limited thereto, and the brush is used for a cleaning tool to clean, for example, a cooking tool or a floor. In addition, it may be configured in a scrubbing shape, a sponge shape or a deck brush shape like a so-called turtle scourer. Here, for example, a sponge-like brush is coated with an abrasive on the other surface facing the one surface (base) of a substantially cubic synthetic sponge, and a plurality of cuts (for example, eyelets) are provided on the other surface. The deck brush has a rod-like handle, a flat plate-like base provided at one end of the handle, and a substantially rectangular base in plan view. And a bristle portion having flexibility, and at least a distal end portion of the bristle portion excluding a base end portion is provided with an abrasive portion having abrasiveness. With such a brush for a cleaning tool, even dirt and foreign matter that cannot be easily removed such as burnt dirt on cooking utensils or dirt on floors and tiles can be removed sufficiently.

  In addition, the brush 1 can be used (configured) for cleaning and stimulating body parts such as elbows and knees, for example, in the cosmetic field. For example, it is provided with a rod-like base portion and a plurality of flexible bristle portions standing on one surface in the longitudinal direction of the base portion, and at least the distal end portion of the bristle portion except for the base end portion is polished. A polishing portion having a property is provided. With such a brush, in addition to a cleaning effect, a beauty and skin beautifying effect can be brought about.

  Moreover, in this embodiment, although the hair part 3 demonstrated the case where it was comprised with the resin molding which consists of synthetic resins, it is not restricted to this, A hair part is the raw material which has flexibility (or elasticity). In addition, it is preferable to be composed of animal hair or natural fibers (for example, palm tree fibers).

  Moreover, in this embodiment, although the hair part 3 demonstrated the case where it comprised and comprised the taper shape which becomes thin as the front-end | tip part side 32a, it is not restricted to this, A hair part is made so that a diameter may become constant. It can also be configured.

  Moreover, in this embodiment, although the hair part 3 demonstrated the case where the diameter of the base end part side 31a is 2.8 mm, the diameter of the front end part side 32a is 1.7 mm, and length is 20 mm, Not limited to this, the hair has a proximal end diameter in the range of 1.8 to 4.1 mm, a distal end side diameter in the range of 0.7 to 3.0 mm, and a length in the range of 5 to 30 mm. It is possible to configure.

  Moreover, in this embodiment, the diameter and front-end | tip of the base end part 31a in the hair part 3 provided in the front side X of the main-body-part surface 2a of the base 2 corresponding to a toe among many hair parts 3 are provided. Although the case where the diameter of the part side 32a is slightly larger than each diameter in the hair part 3 provided on the back side Y corresponding to the heel of the foot has been described, the present invention is not limited thereto. It is preferable that the portion is configured in the same manner as each diameter of the hair portion on the rear side, and it is possible to change the portion according to the surface shape of the object to be cleaned.

  Moreover, in this embodiment, although the hair part 3 demonstrated the case where the space | interval of adjacent hair parts 3 was comprised with 6 mm, it is not restricted to this, A hair part is the space | interval of adjacent hair parts. It is possible to configure the gap in the range of 3 to 10 mm.

  Moreover, in this embodiment, although the bristle part 3 demonstrated the case where it comprised integrally with the base 2, not only this but the bristle was shape | molded separately from the base and the base end part side was formed. It may be configured to be attached to the base.

  Moreover, in this embodiment, although the hair part 3 demonstrated the case where all length was provided with many 20 mm, not only this but the hair part corresponds to the shape of the sole, For example, it is configured to be longer in the order of the center side of the base body surface corresponding to the foot arch, the front side corresponding to the toes, and the rear side corresponding to the foot heel (that is, the center side is the longest, the next It is also preferable that the front side is made longer. Alternatively, the base portion 2 may be configured such that the main body portion surface 2a corresponds to the shape of the soles of the feet, for example, a convex bulge portion corresponding to the foot arch is provided on the center side.

  Moreover, in this embodiment, although the abrasives holding | maintenance part (front-end | tip part 32) of the hair part 3 demonstrated the case where it became a front view cup shape with a flat upper surface, it is not restricted to this, Abrasive material holding | maintenance of a hair part The portion (tip portion) can adopt an uneven shape that holds the abrasive constituting the polishing portion (polishing layer) against the hair portion. For example, it is preferable that the front end portion side of the bristles is configured to have a concave front view cup shape in which the center portion of the upper surface is recessed with respect to the periphery of the upper surface.

  In addition, it is preferable that the distal end side of the bristle has a convex shape in which a protrusion is provided on the outer side in the longitudinal direction. In this case, for example, a cross-shaped groove (cut) is provided on the distal end side of the bristle portion along the longitudinal direction of the bristle portion from the upper surface of the distal end portion, and four protrusions a are formed on the distal end side. Shape (see FIG. 3 (a)), top surface convex shape (see FIG. 3 (b)), which has four substantially circular projections b that taper toward the tip, adjacent to the top surface of the tip, and substantially spherical Can be configured to have a spherical shape (see FIG. 3C) in which one protrusion c is provided on the top surface of the tip.

  Moreover, it is preferable that the front end portion side of the bristle portion is configured with an uneven shape on the side peripheral surface. In this case, the distal end side of the bristle portion has, for example, a shape in which a ridge-shaped uneven portion is provided on the side circumferential surface along the longitudinal direction from the distal end portion of the bristle portion, and is long from the distal end portion of the bristle portion. A vertical hexagonal rib shape (see FIG. 4 (a)) in plan view having six straight convex portions d along the direction, which are spaced substantially evenly in the circumferential direction, from the tip of the hair portion along the longitudinal direction. It is possible to form a substantially hexagonal longitudinal groove shape (see FIG. 4B) in a plan view having six straight concave (groove) portions e that are substantially equally spaced in the circumferential direction.

  Alternatively, the front end portion side of the bristle has a shape in which a convex portion or a concave portion having a substantially circular shape in plan view is provided on the side peripheral surface, and the convex portion f having a substantially circular shape in plan view is straight along the longitudinal direction. The side surface convex shape (refer FIG.4 (c)) by which the convex part f group provided in 2-3 is provided in this shape, and is provided in the linear direction at substantially equal spacing (refer FIG.4 (c)), planar view Two or three substantially circular concave portions g are provided linearly along the longitudinal direction, and four concave portions g provided in the linear shape are arranged in the circumferential direction so as to be spaced substantially evenly from each other.
