  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 to 4 schematically illustrate a brush used for cooking, cleaning, and the like according to the first embodiment by a front view, a bottom view, a plan view, and a cross-sectional view. The brush 10 is composed of a horizontally long, substantially rectangular and thick handle portion 11 and six small brush portions 15 erected at six locations on the bottom surface of the handle portion 11. Hereinafter, with respect to one end and the other end of the brush, the left end in the figure is set to one end and the right end is set to the other end.

  The handle portion 11 is made of resin or wood, and the upper surface 11a and the bottom surface 11b are planes parallel to each other, but the inclined surface 11c is slightly inclined from the center in the longitudinal direction toward the other end at a position closer to the other end side in the bottom surface 11b. It has become. In a portion corresponding to the inclined surface 11c, the side surface 11d of the handle portion 11 is cut off and has a shape projecting in a parabolic shape. Furthermore, an outer peripheral portion 11e having a thickness direction of approximately 1/3 from the upper surface 11a of the side surface 11d is rounded in an arc shape toward the upper surface 11a so that the handle portion 11 can be easily gripped. On the bottom surface 11b on the left side of the inclined surface 11c, there are two attachment holes 12 for attaching the small brush portion 15 from the left end to the right end. They are provided at positions symmetrical in the width direction. Further, a hanging hole 13 is provided in the center of the handle portion 11 in the width direction and in the vicinity of the other end so as to penetrate in the thickness direction, and is used for hanging through a string or the like.

  The small brush part 15 is comprised by the hair | bristle bundle 16 and the resin-made hair | bristle bundle holding member 17 which supports this, as shown in FIGS. The hair bundle 16 is made of natural fiber, made of chemical fiber such as acrylic, polypropylene, PBT, nylon, or other hair material such as animal hair, and is bundled by adjusting the amount, length and mixing ratio of the hair. Alternatively, a single raw material with an adjusted amount and length of bristles is bundled in a cylindrical shape, and approximately half of the longitudinal direction is closely inserted into the entire hair bundle holding member 17. Yes.

  The hair bundle holding member 17 is a thin cylindrical body having a center hole 17a having a cylindrical shape made of resin and having both ends opened. The resin material is ABS, PP, or the like, and preferably has an antifungal property containing silver fine particles. The hair bundle holding member 17 is divided into a lower side portion, an intermediate portion, and an upper side portion that are partitioned by about 1/3 in the longitudinal direction, and the lower side portion includes a fastening portion 18 on the lower end side and a positioning portion on the inside thereof. 19 The positioning portion 19 has a disc shape and has an outer diameter larger than the inner diameter of the mounting hole 12 of the handle portion 11. The tightening portion 18 is formed in a square shape as seen from the axial direction by cutting out four portions in the circumferential direction of the positioning portion 19, and a tightening jig (not shown) is used for tightening the hair bundle holding member 17 in the mounting hole 12. ) To facilitate tightening. The intermediate portion 21 corresponds to an attachment portion, has a slightly smaller diameter than the attachment hole 12, and has a screw groove formed coaxially on the outer peripheral surface. The upper part 22 has a smaller diameter than the intermediate part 21 and has a through hole 23 at one place on the outer peripheral surface. One end side of the hair bundle 16 is inserted into the hair bundle holding member 17, the adhesive 24 is injected into the hair bundle holding member 17, and the hair bundle 16 is impregnated and cured. The part enters the through-hole 23 to form a locking part 24a. The number of through holes 23 is not limited to one and may be two or more.

  Regarding the formation of the small brush portion 15, approximately one end side of the hair bundle 16 is inserted into the whole hair bundle holding member 17, and the through hole 23 of the hair bundle holding member 17 is closed with a tape or the like from the outside to hold the hair bundle. The adhesive 24 is injected into the entire member 17 to impregnate the hair bundle 16 in the hair bundle holding member 17. Thereby, a part of the adhesive 24 that has penetrated into the hair bundle 16 also enters the through hole 23, and the adhesive 24 is hardened to form the small brush portion 15. Here, the bristle bundle 16 is firmly attached to the bristle bundle holding member 17 by the locking portion 24a in which a part of the adhesive 24 enters the through hole 23 and hardens.

  The small brush portion 15 formed in this way is inserted from the upper end side in a state where the adhesive resin 25 is accommodated in the attachment hole 12 of the handle portion 11, so that the positioning portion 19 hits the periphery of the opening of the attachment hole 12. Until inserted. Here, the resin 25 accommodated in the mounting hole 12 and the intermediate portion of the hair bundle holding member 17 are combined with each other so that the adhesiveness is not good, so that the intermediate portion 21 having a screw groove after the resin 25 is cured is used. The hair bundle holding member 17 can be turned and removed from the mounting hole 12, and the small brush portion 15 can be easily replaced.

  According to the first embodiment, the intermediate portion 21 of the hair bundle holding member 17 to which the hair bundle 16 is fixed by the adhesive 24 is substantially screwed to the resin 25 in the attachment hole 12 of the handle portion 11. Thus, the hair bundle holding member 17 is firmly attached to the handle portion 11. As a result, in Example 1, since the tightness of the connection between the hair bundle holding member 17 and the handle portion 11 is maintained even when the brush 10 is used for a long time, the hair bundle holding member 17 from the handle portion 11 is maintained. Can be reliably prevented from falling off. In addition, according to the first embodiment, the hair bundle holding member 17 can be removed from the mounting hole 12 by rotating the hair bundle holding member 17 with respect to the resin 25 using the intermediate portion 21 having a thread groove. . Thereby, since only the small brush part 15 with damaged hair bundle can be selected and replaced easily, the expensive handle part 11 and the small brush part 15 can be effectively used, and the cost of the brush 10 is relatively reduced. Can be reduced. When the brush 10 is discarded, if the handle 11 is made of wood, which is a combustible material, the small brush 15 is non-combustible. Becomes easier.

  Further, according to the first embodiment, a part of the adhesive 24 impregnated in the hair bundle 16 is also integrally filled into the through hole 23 provided in the hair bundle holding member 17 to form the locking portion 24a. Thus, the hair bundle 16 is locked in the through hole 23 by the locking portion 24a. As a result, in Example 1, even if the adhesive force of the adhesive 24 with respect to the hair bundle holding member 17 of the small brush portion 15 decreases due to long-term use of the brush 10, the hair bundle 16 from the hair bundle holding member 17. Can be reliably prevented. Further, since the hair bundle holding member 17 is formed of a resin material having an antifungal property, generation of wrinkles of the hair bundle due to moisture can be suppressed. In the first embodiment, the resin 25 is accommodated in the mounting hole 12, and the intermediate portion 21 of the small brush portion 15 is screwed into the mounting hole 12. You may make it form a screw hole directly.

  Next, Example 2 will be described with reference to the drawings. FIG. 9 is a front view of a foaming brush that is a brush according to Example 2, FIG. 10 is a partially broken cross-sectional view of an integrated hair bundle and a hair bundle holding member, and FIG. The handle part is shown in a partially broken sectional view. The foaming brush 30 includes a columnar hair bundle 31, a hair bundle holding member 32 that holds the hair bundle 31, and a handle 51 that is attached to the hair bundle holding member 32. In the second embodiment, the top and bottom of the brush 30 are aligned with the top and bottom of FIG.

  The hair bundle 31 is a bundle of hair materials similar to the hair bundle 16 described above. As shown in FIGS. 12 and 13, the hair bundle holding member 32 is provided with a thin straight cylindrical cylindrical body 33 made of metal or resin, and an attachment member 38 attached to the lower end in the axial direction. ing. The cylindrical main body 33 has through holes 34 at two positions corresponding to the radial direction at the axially intermediate position. The number of through holes 34 may be one or three or more.

  The attachment member 38 is made of resin, and is integrally provided with a cylindrical central shaft portion 39 and connecting pieces 43 that extend in the direction perpendicular to the axis at three locations that are equally spaced in the circumferential direction of the outer peripheral surface thereof. The central shaft portion 39 has a shaft hole 39a, and has a large diameter portion 41 on the upper end side and a protruding portion 42 having a diameter smaller than that of the large diameter portion 41 on the lower end side. The screw groove is coaxially formed. The connecting piece 43 includes a narrow base rod-shaped base portion 44 having a narrow cross-section projecting slightly in the radial direction from the outer peripheral surface at a boundary position with the projecting portion 42 of the large-diameter portion 41, and an arc shape outward from the tip of the base portion 44. And a base arc 44 extending in the form of a rod-shaped arc 45 having substantially the same cross-sectional shape, and an arc-shaped engagement piece 46 that slightly protrudes outwardly along the outer peripheral edge of the arc 45. .

  The arc portion 45 is gradually expanded radially outward with respect to the large-diameter portion 41, and extends between the tip and the base 44 until the central angle is approximately 90 °, and the tip is in an unconstrained state. Is arranged in. The engagement piece 46 is a thin piece slightly protruding from the end of the arc portion 45 on the protruding portion 42 side. Further, the connecting piece 43 has flexibility and elasticity. Therefore, the arc portion 45 can be bent until it contacts the next base portion 44 in the axial direction and is restored to its original shape by the elastic reaction force. It is possible to return. As a result, the diameter of the imaginary circle connecting the tips of the connecting pieces 43 with the central shaft portion 39 as the center is bent to the maximum value until the arc portion 45 does not bend and until the arc portion 45 comes into contact with the base portion 44. Changes can be made between the minimum values.

  As shown in FIGS. 12 and 13, the attachment member 38 is engaged with one end of the cylindrical body 33 by adjusting the degree of bending of the connecting piece 43 in a state where the protruding portion 42 protrudes downward and outward. The pieces 46 are temporarily attached by overlapping the cylindrical main body 33. Further, for the cylindrical main body 33A whose diameter is about 20% smaller than that of the cylindrical main body 33, as shown in FIGS. 14 and 15, the connecting piece 43 is appropriately bent in the direction of the base 44 to reduce the diameter. Thus, it is possible to overlap the cylindrical main body 33A.

  As shown in FIG. 10, the hair bundle 31 is inserted into a portion of about one third of the length from the upper side in the hair bundle holding member 32, and the hair bundle holding member 32. It has a conical shape that is slightly constricted radially outward with respect to the shaft center from the root to the tip, and the tip surface is slightly convex outward in the axial direction. It has become. An adhesive 35 is injected into the hair bundle holding member 32, and a part of the adhesive 35 impregnated in the hair bundle 31 also enters the through hole 34 to form a locking portion 36 that is cured. As a result, the hair bundle 31 integrally joined by the adhesive 35 is locked to the through hole 34 by the locking portion 36 that has entered the through hole 34, and as a result, the hair bundle 31 becomes the hair bundle holding member. It will be in the state attached firmly to 32. About injection | pouring of the adhesive agent 35 to the hair | bristle bundle holding member 32, like Example 1, the through-hole 34 of the hair | bristle bundle holding member 32 is plugged with a tape etc. from the outside, and the adhesive agent 35 is put in the hair | bristle bundle holding member 32. This is done by injection. Furthermore, the attachment member 38 is fixed to the cylindrical main body 33 as the hair bundle holding member 32 by injecting the adhesive 37 and attaching the attachment member 38 to the cylindrical main body 33 to which the hair bundle 31 is attached. It is formed.

  As shown in FIG. 11, the handle 51 has a wooden columnar shape, and an upper end 53a and a lower end 54a thereof are flat surfaces perpendicular to the longitudinal direction, and an intermediate portion in the axial direction is a shaft over the entire circumference. It is a dent 52 that is recessed in a curved shape toward the center. The upper end side in the axial direction across the recess 52 of the handle portion 51 is a substantially cylindrical mounting portion 53 having a short length, and the lower end side in the axial direction extends radially outward from the vicinity of the lower end in the axial direction. A bulging portion 54 swells in a mountain shape, and has a substantially gourd shape as a whole. The outer diameter of the swollen portion 54 is slightly larger than the outer diameter of the hair bundle 31. Thereby, it has a shape that can be easily grasped by hand by grasping the swollen portion 54 of the handle portion 51 with a hand and applying a fingertip to the recessed portion 52. The attachment portion 53 is provided with a circular attachment hole 55 that is recessed from the upper end surface 53a. The mounting hole 55 has an inner diameter that is equal to the outer diameter of the hair bundle holding member 32 and has a depth that is substantially half the axial length of the hair bundle holding member 32. A screw hole 56 having a screw groove is formed. The hair bundle holding member 32 to which the hair bundle 31 is fixed is inserted into the attachment hole 55 of the handle 51, and the protrusion 42 is screwed into the attachment hole 55. It is fixed and the foaming brush 30 is obtained.

  According to the second embodiment, the attachment member 38, which is a separate member, is attached to the cylindrical main body 33 and adhered by the adhesive 37 injected into the inside thereof, so that one end side of the hair bundle holding member 32 is attached outward. It is possible to easily provide the protruding portion 42 having a thread groove protruding on the surface. On the other hand, since the screw hole is provided in the attachment hole 55 of the handle 51, the hair bundle holding member 32 is firmly attached to the handle 51 by screwing the protruding portion 42 into the attachment hole 55. As a result, in Example 2 as well, even when the brush 30 is used for a long time, the tightness of the connection between the hair bundle holding member 32 and the handle portion 51 is maintained, and thus the hair bundle holding member 32 from the handle portion 51 is maintained. Can be reliably prevented from falling off. Further, when the hair bundle 31 is worn out, the hair bundle holding member 32 can be easily removed from the handle portion 51, and the hair bundle holding member 32 of a new hair bundle 31 can be easily attached to the handle portion 51. Since it can do, the expensive handle | pattern part 51 can be used continuously. Further, when the brush 30 is discarded, since the handle 51 is made of wood that is a combustible material, and the hair bundle 31 and the hair bundle holding member 32 are non-combustible, the hair bundle holding member 32 is removed from the handle 51. This makes it easy to separate garbage.

  Further, since the connecting piece 43 is made of a resin material having flexibility and elasticity, it can be deformed in the radial direction. Therefore, even if the inner diameter of the cylindrical main body 33 is different, the connecting piece 43 can be mounted by being deformed in the radial direction, and is attached to the end of the cylindrical main body 33 by the outer engaging piece 46. By attaching the attachment member 38 to the lower end of the cylindrical main body 33 and adhering it with the adhesive 37 injected into the inside, a protruding portion 42 having a thread groove protruding outward on one end side of the hair bundle holding member 32. Can be easily provided. As a result, in the second embodiment, since the single mounting member 38 can cope with various cylindrical main bodies having different inner diameters, the manufacturing cost and the management cost of the mounting member 38 can be greatly reduced.

  Next, a modification of the second embodiment will be described with reference to the drawings. FIGS. 16 and 17 show a hair bundle holding member of a foaming brush which is a brush according to a modification, in a bottom view and a partially broken front view. In the modification, the attachment member 63 attached to the cylindrical main body 62 of the hair bundle holding member 61 is different from that of the second embodiment. The mounting member 63 is made of resin, and has a cylindrical central shaft portion 64, three rod-shaped connecting pieces 67 extending radially outward at three circumferentially equidistant positions on the outer peripheral surface, and a connecting member 63 An annular portion 68 that integrally connects the distal ends of the pieces 67 is provided integrally. The central shaft portion 64 is the same as the central shaft portion 39, has a shaft hole 64a, and has a large diameter portion 65 on the upper end side and a protruding portion 66 having a smaller diameter than the large diameter portion 65 on the lower end side. A thread groove is coaxially formed on the outer peripheral surface of the protrusion 66. The connecting piece 67 extends radially outward at a boundary position between the large-diameter portion 65 and the protruding portion 66. The annular portion 68 is provided with an arcuate thin engagement piece 69 that slightly protrudes outward along the outer peripheral edge of the protruding portion 66 side end. Thus, unlike the mounting member 38, the mounting member 63 has a constant outer diameter of the annular portion 68. The attachment member 63 is mounted by inserting an annular portion 68 into the lower end of the cylindrical main body 62 and applying an engagement piece 69, and is fixed to the cylindrical main body 62 by an adhesive injected into the cylindrical main body 62.

  In the modified example, unlike the second embodiment, there is a restriction that the outer diameter of the mounting member 63 is constant. By attaching to the cylindrical member 62 having a predetermined inner diameter according to this, one end of the cylindrical member 62 is provided. The protrusion 66 can be easily provided on the side. Therefore, also in the modified example, as in the second embodiment, the hair bundle holding member 61 can be attached to the handle 51 so as not to be detached and easily removable, and the same effect as in the second embodiment is obtained. In addition, the brushes shown in the above embodiments are merely examples, and various modifications can be made without departing from the spirit of the present invention.

  The brush according to the present invention is provided with a screw groove on the outer peripheral surface of the attachment portion of the hair bundle holding member, or a protrusion having a screw groove on the attachment member, and a screw groove in the attachment hole of the handle portion. The hair bundle holding member to which the bundle is fixed by an adhesive is screwed into the attachment hole of the handle, and the hair bundle holding member is firmly attached to the handle. As a result, the present invention maintains the tightness of the connection between the hair bundle holding member and the handle even with long-term use of the brush, and thus can reliably prevent the hair bundle holding member from falling off the handle. Further, the hair bundle holding member is useful because it can be easily detached from the handle.
