Description

  The present invention relates to a strength reinforcing rod and a cleaning method.

  When cleaning the floor surface, etc., garbage that has just been placed on the floor surface can be swept away.For example, in the case of waste oil impregnated on the floor surface of a factory, It is very difficult to sweep away.

  Various types of soot that can remove dust that is difficult to sweep are proposed (see Patent Documents 1 and 2, etc.).

  The technique described in Patent Document 1 has a configuration in which strip-like plates are arranged so as to be adjacent to a bundle of eyelashes, and oil that is difficult to gather only by eyelashes by pressing the plate against the floor surface. The impregnation waste can be removed.

  The technique described in Patent Document 2 makes it possible to sweep away wet dust and the like outdoors by installing a wire in the eyelashes.

  However, in the technique of Patent Document 1, in order to use the strip-shaped plate body portion, it is necessary to curve the eyelash bundle portion, and thus the deformation of the eyelash portion is unavoidable, and the eyelash portion is deformed. In this case, since the strip-shaped plate body comes into contact with the floor surface first, there is a risk that it will hinder normal dust sweeping by the eyelash portion.

  Further, in the technique of Patent Document 2, since the eyelashes and the wire are substantially the same length, the wire always comes into contact with the floor surface or the like, so that normal sweeping only by the eyelash portion cannot be performed. Therefore, there is a risk of damaging the floor surface and the like, so that it cannot be used for cleaning indoors and the like, and it is difficult to delicately sweep fine dust only by the eyelashes.

Therefore, in order to solve the conventional problems described above, the present inventor
A strength reinforcing ridge (Patent Document 3) in which a plurality of lashes are bundled and a lash bundle accommodated in a swingable coil spring is attached to the tip of the handle for strength reinforcement has been proposed.

  Then, the inventor continued further research based on the previously proposed technique. When the coil spring and the eyelash bundle swing and receive frictional resistance during cleaning, as shown in FIG. 19, the stationary state (A) Then, the eyelash bundle 3 uniformly arranged in the coil spring 4 is on both sides (up and down in the drawing) in the sweeping direction (indicated by arrows) of the eyelash bundle 3 at the time of cleaning (B) and (C). It was found that a cavity was formed in the central portion in the coil spring 4 due to separation.

  The separation of the eyelash bundle in the coil spring and the hollowing of the central portion result in a high density portion and a low density portion of the eyelash bundle housed in the coil spring. It turns out that there is still room for improvement.

Therefore, in order to solve the next problem, the present inventor
A strength reinforcing rod having a coil spring winding shape that accommodates the lashes of the strength reinforcing rod so as to be swingable, and at least a triangular shape or other polygonal shape at the head,
A strength-reinforcing ridge in which a coil spring winding shape that stores the eyelash bundle and swingably accommodates at least at the base portion is a quadrilateral or other polygonal shape, and a plurality of eyelash bundles are fixed adjacent to the heel base,
Was devised first. This idea is called prior idea (1) and (2).

Since the eyelash bundle is elastically stretchable and is supplementarily reinforced in a so-called two-waist state in which the so-called waist of the eyelash bundle and the waist of the coil portion itself are added, Since the eyelashes are soft, the damage of the eyelashes of the eyelash bundle is suppressed, and the sweeping by point contact at the sharp tip of the eyelashes, which is the most sweeping and efficient at the time of sweeping, is applied to the surface to be cleaned. This is possible in a state where the following performance is good. That is, the eyelash bundle is prevented from being in a state of being shattered at the time of cleaning work, the tip of the eyelash bundle is in a sleeping state, and the surface to be cleaned is only stroked at the abdomen instead of the tip of the eyelash bundle. It can suppress falling into a state.
Therefore, even waste dust impregnated with waste oil stuck to the floor of the factory can be swept away and removed.

  According to the sixteenth aspect of the present invention, it is possible to prevent the surface to be cleaned from being damaged during use without suppressing the effect as a wrinkle that is a sweeping effect during cleaning. Further, by covering the sharp portion of the coil spring winding end portion generated in the coil spring manufacturing process with the covering portion formed of the soft resin, it is possible to prevent the surface to be cleaned from being damaged by the sharp portion. There is also an accompanying effect.

According to the invention described in claim 17, when the winding shape of the head of the coil spring is a square or other polygon, the eyelash bundle in the coil spring is separated so as to escape to both sides in the sweeping direction during cleaning. There is no air gap in the central portion, and the air gap is in the forward direction in the sweeping direction. This is because when the coil spring is cylindrical, the eyelash bundle escapes outward along the round inner wall formed by the inner side of the coil spring, so that it separates on both sides in the sweeping direction. By making the winding shape of the spring a quadrilateral or other polygon, each corner of the quadrilateral or other polygon serves as a stopper to prevent each eyelash moving within the coil spring from escaping to both sides of the sweeping direction. This is because it works.
Therefore, the density of the eyelash bundle stored in the coil spring does not increase or decrease, and sweeping with a uniform density becomes possible.

  According to the invention shown in claim 18, it is possible to obtain a cocoon having a shape in which a plurality of eyelash bundles are arranged in parallel in the horizontal direction (the shape of a tatami mat).

  According to the nineteenth aspect of the present invention, the variation of the eyelash bundle can be suppressed.

  The upper cuff 10A, the lower cuff 10B, and the cuff coupling portion 10C have strength and shape that can maintain a stable state when the user performs an operation during cleaning while inserting the forearm and holding the grip portion 9. Specifically, for example, it is preferable that the structure is formed of a synthetic resin material such as ABS or a metal material such as aluminum or stainless steel and the surface is covered with a cushioning material serving as a buffer material. Further, the forearm support portion 10 may have flexibility as long as it is formed with a strength and a shape capable of maintaining a stable state as described above. By having flexibility, it not only protects the user's arm from impacts such as the reaction from the floor surface that occurs when sweeping during cleaning, but also reduces fatigue, as well as repetitive sweeping motion by pendulum motion Sometimes momentum can be added.

  In this embodiment, the attachment means 10D for attaching the forearm support portion 10 to the handle 6 may be attached with a tape-like member or a band-like member as shown in FIG. 2, or attached using a fixing member such as a bolt. It may be. Further, the forearm support portion 10 is preferably detachably attached to the handle 6, but may be configured integrally with the handle 6.

  The forearm support portion 10 has a configuration in which the upper cuff 10A and the lower cuff 10B, which are two annular bodies in the present embodiment, are coupled by the cuff coupling portion 10C, but the present invention is not limited to this, and the number of annular bodies is One may be sufficient and three or more may be sufficient. Moreover, if it is the structure which can insert a user's forearm, it will not be limited to a cyclic | annular body, For example, you may be comprised by the cylindrical body as shown in FIG. In addition, when the forearm support part 10 is comprised with a cylindrical body, it is preferable to provide several through-holes, such as a punching hole, or to form in mesh shape from a lightweight point and a breathable point.

  In the present embodiment, the grip portion 9 provided on the handle 6 is preferably provided with a grip member made of rubber material, sponge material, resin material or the like so that the user can easily grip it. However, the grip portion 9 indicates a portion that is simply gripped by the user during cleaning, and a mode in which a grip member as shown is not provided is also included in the present invention.

  The eyelash bundle 3 is configured to become the eyelash bundle 3 by inserting about 20 to 60 eyelashes 2 in a bundle, and approximately 30 eyelashes 2 into a planting hole formed in the eyelash substrate 5.

  The material of the eyelashes 2 of the eyelashes 1 is the same as that of publicly known eyelash materials. In addition to natural materials such as bamboo branches, scallops, palms, ferns, straws, and hagi, synthetic resins, brass, stainless steel, copper You may use materials, such as metals, such as.

  In addition, the eyelashes 2 can be used not only having the same material and the same diameter but also combining two or more types of different materials and different diameters.

  A known coil spring 4 made of metal, synthetic resin, or the like is used as the swingable coil spring 4 that is a cylindrical body that houses the eyelash bundle 3. When it is made of metal, it may be coated with a synthetic resin.

  As shown in FIG. 4, the tip of the eyelash bundle 3 protrudes from the lower end (head) of the coil spring 4, and the extent of such protrusion is that of the eyelash bundle 3 with respect to the length L of the eyelash bundle 3. For example, when the length L of the eyelash bundle 3 is 5 to 30 cm, l is preferably 1 to 10 cm.

  At least at the head 4C of the coil spring 4, the eyelash bundle 3 is housed in a non-dense state, that is, housed in the coil spring 4 so that the eyelash bundle 3 can swing. As will be described later, by configuring the diameter of the coil spring 4 so that the head 4C is larger than the root 4A, the density of the eyelash bundle 3 at the head 4C is smaller than the root 4A. .

  It is preferable that at least a part of the eyelash bundle 3 and the coil spring 4 that houses the eyelash bundle 3 are in close contact with each other, and in particular, the root portion on the side of implantation into the eyelash substrate 5 is in close contact. preferable. Although influenced by the flexibility of the coil spring 4, the flexibility and suppleness of the eyelashes 2 as the eyelashes can be changed by the degree of close contact with the eyelash bundle 3. That is, when comparing the coil springs 4 having the same hardness and flexibility, it is harder to be more closely attached to the eyelash bundle 3 to be housed.

  The coil spring 4 has a triangular shape such as a triangle at least at the head 4C. The triangle and other polygons are preferably substantially regular triangles as shown in FIGS. 4, 7 and 8, but may be substantially squares as shown in FIG. Further, it may be another triangle such as an isosceles triangle or a right triangle (for example, the shape of the head 4C of the coil spring 4 at the left and right ends in FIG. 8), or may be another rectangle such as a rectangle, a parallelogram, or a trapezoid. However, other polygons such as a pentagon may be used. The triangular and other polygonal coil springs 4 can be formed by using a publicly known forming machine which is a forming machine for deformed coils or the like. The portion excluding the head 4C may have the same winding shape as that of the head 4C, that is, a triangle or other polygons, or other shapes, that is, a circle or an ellipse, May be triangular or other polygons of different shapes.

The present invention also includes a configuration that expands automatically.

  For example, when the diameter of the root portion 4A is 2.5 mm, the diameter of the tip portion 4B is preferably about 3.5 mm.

  When the eyelash bundle 3 and the coil spring 4 containing the eyelash bundle 3 are implanted in the eyelash substrate 5, the end of the coil spring 4 is bent upward to prevent the eyelash 2 from falling off the eyelash bundle 3. It is preferable that the upper end of the coil spring 4 serves as a stopper for preventing the slipping in the planting hole by being inserted into the planting hole of the rod base 5 in a state where the coil spring 4 is in the state.

  In this embodiment, the coil spring 4 is a close coil portion in which the head portion 4C is in close contact with the adjacent coil portion, and the other portion is a coarse coil portion in which the adjacent coil portion is separated. However, a part or all of the part other than the head 4C may be a contact coil part.

  The close contact coil portion of the head 4C of the coil spring 4 is preferably in close contact with 2 to 7 turns, and more preferably with close contact with 3 to 5 turns. Further, when the portion other than the head 4C is a coarse coil portion, the coarse coil portion is preferably composed of at least one turn.

The covering portion 7 includes not only the close contact coil portion but also a part of the coarse coil portion continuous to the close contact coil portion, so that the sweeping is performed as compared with the case where only the close contact coil portion that is the head 4C is covered. It is possible to prevent the covering portion 7 from being peeled off or dropped off when a load such as shifting is applied. That is, by covering up to a part of the coarse coil portion continuous to the close-contact coil portion, the covered portion of the coarse coil portion serves as a stopper for preventing the covering portion 7 from peeling off or from falling off.

  The part of the portion covered with the covering portion 7 of the coarse coil portion is preferably at least one turn continuous to the contact coil portion, but may be one third or more of one turn, and about two turns. If it is enough.

  The portion covered with the covering portion 7 is not limited to the close contact coil portion that is the head portion 4C shown in FIG. 6 and a part of the coarse coil portion that continues to the close contact coil portion, but only the close contact coil portion that is the head portion 4C. It may be all of the contact coil portion and the coarse coil portion.

  The covering portion 7 may be wound or knitted with a filament yarn made of a soft resin fiber around the wire of the coil portion, or may be immersed in a molten soft resin solution.

  The coil portion of the wire material can be covered with multifilaments such as spiral winding in which right-handed and left-handed overlap, right-handed or left-handed spiral winding, and braided knitting. The filament yarn may be a single type of filament yarn applied to the wire of the coil portion, or may be applied in combination with another type of filament yarn. In combination with other types, when the applied mode is the above-described overlapping spiral winding, one is right-handed and the other is left-handed. In the case of braided knitting, braided knitting with two types of filament yarns may be used. .

  In the case of coating with a soft resin resin fiber, it may be fixed with an adhesive such as a nylon adhesive. Examples of the adhesive include a solution in which about 15% of methoxymethyleneated nylon is dissolved in methanol. The adhesive can be applied by appropriate means such as dipping and coating. Generally, after the wire material of the coil portion coated with the multifilament is immersed in the solution, it is dried and cured at about 130 to 150 ° C.
