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 above-described conventional problems, the present inventor bundles a plurality of eyelashes and attaches the eyelash bundle housed in a swingable coil spring to the tip of the handle for strength reinforcement. A reinforcing rod was proposed previously (Patent Document 3).

  ADVANTAGE OF THE INVENTION According to this invention, the density of the eyelash bundle can be equalize | homogenized, and the strength reinforcement | strengthening wrinkles which improved the sweepability, and the cleaning method using the same can be provided.

According to the first aspect of the present invention, when the coil spring has a triangular or quadrangular winding shape, the eyelash bundle in the coil spring is separated so as to escape to both sides in the sweeping direction at the time of cleaning, and a gap is formed in the central portion. It does not occur, and a gap is generated in front of 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 inside of the coil spring and separates to both sides in the sweeping direction. the winding shape of the spring by a triangular or quadrangular, in order to each corner portion of the triangular or quadrangular acts as a stopper to prevent the escaping direction sides asked the broom bristles sweep moving within a coil spring is there.
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 2 or 3, since the eyelashes can be spaced from each other at the tip portion of the eyelash bundle, each eyelash is point-contacted, and the floor or the like is cleaned like a sharp cutting edge. In addition to being in contact with the surface, each of the eyelashes can be swung without being restricted in movement in the entire 360-degree circumferential direction, and the dust sweeping property is further improved.

According to the fourth aspect of the present invention, during cleaning, not only simple reciprocation or rotational movement in one direction but also a sharp bow while warping in the 360 ° circumferential direction starting from the tip of the eyelash of the eyelash bundle. The close contact coil part can prevent the tip of the eyelashes of the eyelash bundle from jumping out from the side of the coil spring even with respect to the swinging movement and the irregular rotational movement. Since the eyelash bundle is elastically stretchable, it is supplementarily reinforced in a so-called two-waist state where the so-called waist of the eyelash bundle and the waist of the coil part 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 crushed state during cleaning work, and 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 fifth 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 of sweeping effect during cleaning. In addition, the sharp portion of the coil spring winding end portion generated in the coil spring manufacturing process is also covered with a soft resin, thereby preventing the surface to be cleaned from being damaged by the sharp portion. can get.

  According to the invention shown in claim 6, it is possible to prevent the tip of the eyelash of the eyelash bundle from jumping out from the side of the coil spring.

  According to the seventh aspect of the present invention, when the close contact coil portion of the spring coil is covered with the soft resin, at least one winding portion is for preventing the soft resin from being peeled off. And / or since it serves as a stopper for preventing falling off, it is possible to prevent the soft resin from being peeled off or dropped off.

  According to the eighth aspect of the present invention, since the large-sized brush that sweeps large dust and the small-sized brush that sweeps fine dust can be cleaned while assisting each other, the sweeping property is good. Become.

  According to the ninth aspect of the present invention, even when a plurality of eyelash bundles housed in the coil spring are planted side by side in a closely aligned state, a gap is generated between the heads of adjacent coil springs. Therefore, the density of the eyelash bundle does not increase or decrease, and sweeping with a uniform density becomes possible. Therefore, when a plurality of eyelash bundles are planted in a state where a plurality of cylindrical coil springs are arranged, it is possible to eliminate a gap that occurs between adjacent coil springs.

  According to the tenth aspect of the present invention, it is possible to perform a cleaning operation that can sweep up without damaging the surface to be cleaned such as a floor surface, regardless of the state of dust that is difficult to sweep up.

  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.

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

  As shown in FIG. 2, 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 portion 4C is larger than the root portion 4A, the density of the eyelash bundle 3 at the head portion 4C is smaller than the root portion 4A portion. .

  It is preferable that at least a part of the eyelash bundle 3 and the coil spring 4 that accommodates the eyelash bundle 3 is in close contact with each other, and it is particularly preferable that the root portion on the side of implantation into the base 5 is in close contact. . 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 or a quadrangular winding shape at least at the head 4C. The triangle or quadrangle is preferably a substantially regular triangle as shown in FIGS. 2, 5 and 6, but may be a substantially square 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. 6), or may be another rectangle such as a rectangle, a parallelogram, or a trapezoid.

Note that “gradually expanding” is literally not only in a state of gradually expanding as shown in FIG. 3A, but also by forming a step 4D in the middle as shown in FIG. 3C. 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 base body 5, the end of the coil spring 4 is bent upward in order 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 to prevent the coil spring 4 from slipping out by being inserted into the planting hole of the base 5 in a 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.

  Moreover, as shown in FIG. 4, it is preferable that the coil spring 4 coat | covers a close coil part which is the head 4C, and a part of coarse coil part which continues to this close coil part with a soft resin. Compared to the case where only the close contact coil portion, which is the head 4C, is covered by forming the cover portion 7 made of a soft resin including not only the close contact coil portion but also a part of the coarse coil portion continuous to the close contact coil portion. Thus, it is possible to prevent the covering portion 7 from being peeled off or dropped off when a load such as sweeping 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 portion of the coarse coil portion covered with the soft resin is preferably at least one turn continuous to the close contact coil portion, but may be one third or more of one turn, and may be about two turns. Is enough.

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