Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a brush in which a brush rod made of bundled strands is removably implanted in a brush carrier.

Prior Art As a method of forming brush wires into small bundles and implanting a large number of small bundles into a brush carrier such as a base plate at multiple points in a staggered arrangement or a grid-like arrangement, for example, each bundle of brush wires is placed on a brush carrier. You can fold it in half and fix the bent part using staples, or as shown in Utility Model Publication No. 56-51783, a large number of flocking holes are penetrated through the base plate and a set of adjacent flocking holes are inserted. There is a known precedent example in which a brush wire folded in half is pulled through and press-fitted so as to straddle the hair.

Problems that the invention aims to solve: However, in the former case, each bundle of brush wires must be stapled one by one, which is a complicated process, and stapling does not allow the brush bundles to stand upright. In addition to its drawbacks, the base plate is limited to materials that can be driven by staples.

Moreover, the latter prior art requires a complicated work in which a bundle of brush wires folded in half must be threaded through an adjacent hole and straddled. Furthermore, since the bent portions of each bundle of brush wires protrude from the back surface of the base plate, it is difficult to stably install the brush wires on a flat surface.

Moreover, a brush with long bristles is required for each unit bundle, which is not only uneconomical, but also has the disadvantage that the above-mentioned implantation method tends to cause unevenness in the tips of the bristles and hair breakage.

Also, in any of the preceding examples, the upright state of each bundle,
Since the rigidity in the upright state cannot be maintained, the cleaning effect is inferior. Furthermore, it is difficult to insert and remove each small bundle of brushes from the brush carrier for replacement or repair.

Means for Solving the Problems The present invention, as a means to solve the above-mentioned problems, is to insert the brush rod from the tip of the bristles through the opening at the lower end of the insertion hole formed through the brush carrier, and to make the rod stand upright above the brush carrier. By engaging the engagement claw formed by extending the adhesive base of the brush rod into an annular shape with the annular taper or stepped portion formed at the lower opening edge of the insertion hole, the carrier can be removed downward while being prevented from being removed upward. This is what I did.

Function As mentioned above, a brush rod is formed by converging a large number of short brush wires and melting and bonding the base portions or hardening them with an adhesive. At this time, the retaining pawl is formed by extending the molten material or adhesive around the periphery. In this way, a single straight brush rod is formed which has an appropriate dispersibility at the tip and is joined and bundled at the lower end.

By inserting the above-mentioned single straight brush rod from the bristle tip side through the lower end opening of the brush insertion hole penetrating the brush carrier, the retaining claw formed by the adhesive part at the base of the brush rod can be attached to the lower end opening edge of the brush insertion hole. Engages with the annular taper or step of the tube to achieve upright implantation.

Each brush rod is implanted in such a way that it is prevented from coming out above the brush carrier by a retaining claw at the base of the rod, and can be removed below the brush carrier,
In addition, the base of the brush rod is restrained by the inner wall of the brush insertion hole to ensure the above-mentioned upright state above the carrier.

Embodiments Embodiments of the present invention will be described below with reference to FIGS. 1 to 5.

As mentioned above, the implanted brush according to the present invention consists of the brush rod 1 and the brush carrier 2.

As shown in the figure, a large number of fixed-sized short brush wires 1a shaped into a straight or wavy shape with high rigidity are bundled into a small bundle, the base of which is bonded by heat fusion, and a solid is attached to the base. A rod-shaped brush rod 1 having a root portion 1b is formed. Alternatively, instead of heating and fusing, the base portions of the small bundles of brush wires 1a are bonded together using an adhesive to form the brush rod 1. The brush rod 1 has an appropriate dispersibility at the tip, and becomes a straight brush rod that is condensed and bound by the solid root portion 1b at the lower end.

An annular retaining pawl 1c is formed by projecting the end of the solid root portion 1b into an annular shape. The annular retaining pawl 1c is formed by forming the brush wire 1a into a small bundle and applying pressure to the end face during the above-mentioned welding. Alternatively, in the case of using adhesive, a lump of adhesive is stretched out in an annular shape to form the above-mentioned retaining claw 1c.

On the other hand, as shown in FIG. 1, a rectangular or disc-shaped base plate 2a is used as the brush carrier 2, and a large number of brush insertion holes 3 are provided in the base plate 2a in a base pattern or staggered arrangement. An annular taper 3a or an annular step is formed at the lower opening edge of the hole 3.

Then, the brush rods 1 are tightly inserted into each of the insertion holes 3 from their lower end openings, and while the bases of the brush rods are restrained by the inner walls of the insertion holes 3, the bristles are made to stand upright above the base plate 2a, forming an annular shape. The solid root portion 1b is pushed into the air space within the taper 3a and its engaging claw 1c is engaged with the annular taper 3a to prevent the brush rod from coming off in the insertion direction (toward the tip of the rod bristles). That is, the brush rod 1 is slid into the brush carrier 2 from below so that it can be inserted and removed, but cannot be inserted or removed above the brush carrier.

As a result of the above, an implanted form is formed in which the brush rods 1 stand upright so that they can be inserted and removed using the adhesive base, and each brush rod is maintained in an upright state. Moreover, each brush rod 1 has sufficient upright rigidity and does not shed bristles, forming a dot-like aggregate pattern in brush rod units.

As an embodiment of the present invention, the dot-shaped aggregate pattern of the brush rod units is used, and each brush rod 1 is colored as shown in FIG. Hole 3
The pattern P of characters, symbols, etc. is expressed by the collection of the patterns P. This pattern is, for example, the initial of a person's name.

In yet another embodiment, as shown in FIG. 3, the base plate 2a serving as a carrier on which the brush rod 1 is installed in an upright manner as described above may be shaped like a U as shown in FIG. 3A or in a frame shape as shown in FIG. 3B. The male and female engaging portions 4 are formed by fitting into the holding plate 4 of
At step a, snap it into place to make it one piece.

Furthermore, FIG. 4 shows another example in which the base plate 2a on which a large number of brush rods 1 are installed in an upright manner as described above is directly attached to the ski board 5, or a holding plate as shown in FIGS. 3A and B is used. 4 to the ski 5 and the holding plate 4
2 shows a case where the brush planting base 2a is removably attached. In this case, preferably the brush planting platform 2a is located at the rear of the ski shoe trapping seat 6, and the brush planting platform 2a is placed at the rear of the ski shoe trapping seat 6 before the skier fills the trapping seat 6 with the ski boots. The snow that has frozen on the sole of the shoe is scraped off, and the shoe can be immediately mounted on the catching seat 6.

Furthermore, in FIG. 5, instead of using the flat base 2a as a brush carrier, a cylindrical body 2b is provided with a large number of insertion holes 3 penetrating from its outer peripheral surface to its inner peripheral surface, and the brush rod 1 is inserted into each of the insertion holes 3. Each brushrod unit is planted in radial rows in the following manner.
In this case, another cylindrical body or a cylindrical body is tightly inserted into the inner peripheral surface of the cylindrical body 2b to press the solid root portion 1b of each of the brush rods to prevent the cylindrical body 2b from slipping inward.

Effects of the invention As explained above, the present invention consists of a brush rod formed by converging short brush wires and bonding their bases, and inserting the brush rod from the tip of the brush into the brush insertion hole from the lower end opening of the brush insertion hole penetrated through the brush carrier. The group of brush rods is inserted into the brush carrier in an upright manner, and is implanted in a downward direction by engaging the retaining pawl with the adhesive portion overhanging the annular taper or the stepped portion formed at the lower opening edge of the brush insertion hole. It is possible to prevent the brush rods from coming off, and it is extremely easy to install the brush rods upright on the brush carrier and to form a brush with a brush rod collection pattern.

The base of each brush rod is well prevented from coming out by the annular taper or the stepped part formed at the lower opening edge of the brush insertion hole by the retaining pawl, and the bristles are restrained by the inner wall of the brush insertion hole following the stepped part. It is possible to maintain the upright side of the plant well and plant it.
Coupled with the uprightness of the brush rod itself due to the above-mentioned configuration, it is possible to prevent excessive shedding of the tips of the bristles, maintain good upright rigidity, and improve the cleaning effect. Furthermore, each brush rod can be inserted into and removed from the brush insertion hole from below, making it easy to replace the brush rods.

In addition, a desired brush rod can be easily formed by simply converging the brush wires and hardening the base by melting or using an adhesive, and in addition, this bonded portion can be used to form the above-mentioned pull-out prevention claw to form an effective pull-out prevention means. .
