Description

  The present invention relates to a brush.

  Brushes for cleaning railway vehicles and automobiles generally have a structure in which brush fibers are planted on a brush base. For example, JP2013-79030A describes a car wash brush in which a cleaning body including a line cleaning body and a surface cleaning body is formed in a cylindrical shape and attached to a rotating shaft.

  Further, wood, vinyl chloride, and the like are known as materials constituting the brush base. For brush stands made of wood, brush fibers can be planted using a machine.

JP2013-79030A

  However, the operation of planting brush fibers on a brush base made of a material containing a synthetic resin such as vinyl chloride cannot be carried out using a machine. Therefore, conventionally, the manufacture of a brush using a brush base such as vinyl chloride has been manually performed from the formation of a mounting hole of the brush fiber to the brush base to the flocking of the brush fiber. Here, the flocking work of the brush fiber is a process in which a portion where the brush fiber is bent in a U-shape is inserted into the mounting hole, and the portion is sewn with a knitting thread such as Tegs, which requires a particular technique. For this reason, it has been difficult to manufacture a conventional brush with a simple operation.

  The present invention has been made to solve the above problems. The main object of the present invention is to provide a brush to which a plurality of cleaning bodies can be attached by a simple operation.

  The brush of the present invention includes an outer peripheral surface and a side surface intersecting the outer peripheral surface, and includes a main body portion having a groove that opens on both the outer peripheral surface and the side surface, and a brush portion attached to the groove of the main body portion. . The brush part includes a plurality of cleaning bodies and a holder for holding each end of the plurality of cleaning bodies, and the brush part is attached to the groove by inserting at least the holder into the groove.

  According to the brush of the present invention, a plurality of cleaning bodies can be attached to the main body at a time by inserting a holder for holding the plurality of cleaning bodies into the groove. Thereby, it becomes possible to attach a some washing body to a main-body part easily.

  In the brush, the brush part further includes a wire. A wire is arrange | positioned so that it may be pinched | interposed by the washing | cleaning body bent so that it might return. The holder is configured to wind a wire and a cleaning body that sandwiches the wire from the outside. Thereby, a some washing body is attached to a main-body part in the state fixed between the wire and the holder. Therefore, even when the brush is rotated at a high speed, it is possible to prevent the cleaning body receiving the centrifugal force from coming out of the main body.

  In the brush, the holder has a width larger than the width of the opening in the outer peripheral surface of the groove. As a result, it is possible to prevent the holder from coming out of the opening on the outer peripheral surface of the groove, so that even when the brush is rotated at a high speed, the cleaning body that has received centrifugal force is prevented from coming out of the main body. be able to.

  In the brush, the groove includes at least one of a groove portion extending along the axial direction of the main body portion, a groove portion extending obliquely with respect to the axial direction, and a groove portion extending orthogonal to the axial direction. . Even if it does in this way, a washing body can be arranged along the peripheral direction of a main part. Therefore, by rotating the brush at high speed with respect to the object to be cleaned, the cleaning body can be effectively brought into contact with the object to be cleaned, and the cleaning efficiency can be improved.

  The brush further includes a band wound around the outer peripheral surface of the main body so as to be positioned on the outer periphery of the holder inserted in the groove. This band can prevent the holder from coming out of the opening in the outer peripheral surface of the groove even when the brush is rotated at a high speed.

  In the brush, the main body may have a cylindrical shape. Even if it does in this way, since a holder can be inserted in a groove | channel from the end surface located in the both ends of the axial direction of a main-body part, a cleaning body can be planted by simple operation | work with respect to a main-body part.

  In the brush, the main body has two semi-cylindrical parts combined so as to have a cylindrical shape. If it does in this way, a holder can be inserted in a slot from the end face located in the both ends of the direction of an axis of a semi-cylindrical part, or the peripheral end face located in the end of the direction of the circumference of a semi-cylindrical part. Therefore, it is possible to plant the cleaning body with a simple operation on the main body.

  In the brush, the main body is made of a synthetic resin. In the brush according to the present invention, since a holder for holding a plurality of cleaning bodies is attached to the main body portion by being inserted into the groove, the plurality of cleaning bodies can be easily attached to the main body portion made of synthetic resin. Can be attached.

In the radial cross section of the main body 1, the groove 2 is provided such that the width W1 of the opening facing the outer peripheral surface S1 is narrower than the maximum width W2 at the bottom. The width W1 of the opening of the groove 2 is, for example, about 4 mm, and the maximum width W2 at the bottom of the groove 2 is, for example, about 8 mm. The dimension in the radial direction of the main body 1 of the groove 2 is, for example, about 7 mm. The shape of the groove 2 in the radial section of the main body 1 is only required to be changed from the width W1 to the width W2 in the radial direction of the main body 1. For example, a circular shape and a linear shape are combined. Shape. The thickness T2 of the main body 1 at the end on the inner peripheral surface S2 side of the groove 2 is, for example, about 3 mm.

  Referring to FIG. 4, the end 4 b located on the opposite side of the end 4 a of the cleaning body 4 is a portion that contacts a vehicle or the like that is the object to be cleaned. The material constituting the cleaning body 4 is mainly polypropylene or polypropylene, for example. For example, the length L of the cleaning body 4 in a folded state is about 400 mm to 600 mm, and the wire diameter is about 0.2 mm to 0.4 mm. The shape of the cleaning body 4 in the cross section perpendicular to the direction in which the cleaning body 4 extends may be any shape, for example, a circular shape or a polygonal shape.

  With reference to FIG. 2, the brush portion 3 may have a region RA where the cleaning body 4 is provided in a direction in which the brush portion 3 extends and a region RB where the cleaning body 4 is not provided. In this case, preferably, the region RB where the cleaning body 4 is not provided is formed so as to be sandwiched by the region RA where the cleaning body 4 is provided, and the region RB where the cleaning body 4 is not provided is cleaned. It is narrower than the region RA where the body 4 is provided. For example, in the direction in which the brush part 3 extends, the length of the region RB where the cleaning body 4 is not formed is about 10 mm. Further, a plurality of regions RB where the cleaning body 4 is not formed may be provided in the brush portion 3.

  In the state in which the brush portion 3 is configured, the holder 6 sandwiches only the cleaning body 4 on the side where the end portions of the plate-like members overlap (the side extending to the end portion 4b of the cleaning body 4). The cleaning body 4 and the wire 5 are sandwiched between the bent portion side of the member (the side including the end 4a of the cleaning body 4). Therefore, as shown in FIG. 4, the width W3 of the portion where the holder 6 holds only the cleaning body 4 is smaller than the maximum width W4 of the portion where the cleaning body 4 and the wire 5 are held. At this time, the shape of the folded portion of the holder 6 is provided so as to be fitted to the groove 2 according to the shape of the groove 2 of the main body 1. In the present embodiment, the shape of the holder 6 is, for example, a shape in which a circular shape and a linear shape are combined. Further, the width W3 (FIG. 4) of the holder 6 is approximately the same as the width W1 (FIG. 3) of the opening of the groove 2, and the width W4 (FIG. 4) of the holder 6 is the width W2 of the groove 2 (FIG. 4). It is equivalent to 3). Further, the holder 6 may be bonded to the groove 2 with an adhesive or the like.

  The brush 10 is configured by arranging the brush portions 3 as described above one by one in one groove 2 formed in the main body portion 1. The brush 10 can clean the object by bringing the cleaning body 4 into contact with the object to be cleaned in a state where the brush 10 is rotated with the central axis of the main body 1 as the rotation axis A (FIG. 1), for example. Preferably, a plurality of brushes 10 are provided so as to sandwich the object to be cleaned, and a pair of brushes 10 facing each other with the object to be cleaned are rotated in opposite directions by, for example, a motor or the like. In this way, the object to be cleaned can be effectively cleaned.

Next, an example of assembly work of the brush 10 will be described.
First, the main body 1 is prepared. Specifically, after preparing two main body parts 1 that are semi-cylindrical and made of vinyl chloride, a plurality of grooves 2 are formed in each main body part 1. For example, the groove 2 is formed by first forming an opening having a width W <b> 1 in the circumferential direction of the main body 1 along the axial direction of the main body 1 on the outer peripheral surface S <b> 1 of the main body 1. Next, a bottom portion having a maximum width W2 in the circumferential direction of the main body 1 is formed on the inner peripheral surface S2 side with respect to the opening.

  Next, a plurality of brush portions 3 are prepared. The brush unit 3 is a so-called unit brush. Next, each brush part 3 is attached to a plurality of grooves 2 provided in the main body part 1. For example, the holder 6 positioned at the end in the extending direction of the brush portion 3 with respect to the groove 2 exposed on the end surface S3 so that the end 4b of the cleaning body 4 is disposed outside the outer peripheral surface S1. Then, the brush portion 3 may be fed in the direction in which the groove 2 extends (in the present embodiment, the axial direction of the main body portion 1). In this way, the plurality of brush portions 3 can be attached to the plurality of grooves 2 of the main body portion 1. At this time, the groove 2 and the brush portion 3 may be bonded to each other with an adhesive or the like with the brush portion 3 attached to the groove 2.

  Next, the two main body portions 1 are combined to form a cylindrical brush base. Next, the band 7 is wound around the outer peripheral surface S1 of the brush base (main body 1). In this way, the brush 10 according to the present embodiment is produced.

  Next, the effect of the brush according to the present embodiment will be described in comparison with the comparative example shown in FIG. Referring to FIG. 10, a conventional car wash brush has a structure in which a plurality of holes 21 and 22 are provided in a semi-cylindrical body portion 15 and a cleaning body 40 is knitted in each of the holes 21 and 22. doing. Each of the holes 21 and 22 includes a knitting yarn hole 21 through which only the knitting yarn 50 is passed, and a cleaning body hole 22 into which a cleaning body 40 larger than the inner diameter of the knitting yarn hole 21 is inserted and fixed. It is configured. Further, the conventional brush assembly method is such that after forming the above-described two holes 21 and 22 in the main body portion 15, the cleaning body is formed in each hole 22 using the knitting yarn 50 wound around the inner peripheral surface of the main body portion 15. The brush is produced by weaving 40 and further bonding the cleaning body 40 to the hole 22 with an adhesive or the like. Therefore, the assembly of the conventional brush is performed manually by a craftsman. In particular, since the flocking work for sewing the cleaning body 40 into each hole 22 requires a technique, a brush capable of flocking by a simple work is required.

  On the other hand, the brush according to the present embodiment is provided with a groove 2 that is open on both the outer peripheral surface S1 and the end surfaces S3 and S4 of the main body 1, and the brush 2 extends from the end surface S3 or S4 to the groove 2. By inserting the holder 6 of the part 3, the brush 10 to which the brush part 3 is attached can be easily produced. That is, the brush portion 3 can be attached to the main body portion 1 (the washing body 4 can be planted) without performing a manual knitting operation.

  Furthermore, the brush part 3 is comprised by crimping | bonding with the wire 5 with the holder 6 in the state in which the washing body 4 was arranged with respect to the wire 5. FIG. That is, the cleaning body 4 is arranged so as to sandwich the wire 5, and the cleaning body 4 is sandwiched together with the wire 5 by the holder 6. Therefore, even when the brush 10 rotates at high speed, the wire 5 and the holder 6 can prevent the cleaning body 4 from receiving the centrifugal force and coming out of the holder 6.

  Furthermore, the holder 6 has a width W4 that is larger than the width W1 of the opening in the outer peripheral surface S1 of the groove 2. Specifically, the width W3 of the portion holding only the cleaning body 4 in the holder 6 is set to be approximately the same as the width W1 of the opening of the groove 2, but in the holder 6, the cleaning body 4 and the wire 5 is larger than the width W3. Therefore, for example, when the brush 10 is rotated at a high speed, the brush portion 3 can be prevented from coming out from the main body portion 1 to the outer peripheral side.

  In the present embodiment, the brush base is configured in a cylindrical shape by combining two semi-cylindrical body portions 1, but is not limited thereto. Referring to FIG. 6, for example, the brush base may be divided into a plurality of stages in the axial direction. In this case, the brush base is composed of a semi-cylindrical body portion 1 that is twice the number of steps. At this time, the brush base may be configured such that several kinds of main body portions 1 having different axial lengths are stacked in the axial direction. For example, when the brush 10 having an axial length of 2.5 m is configured, ten semi-cylindrical body portions 1 having an axial length of 500 mm may be prepared. In addition, for example, three types of semi-cylindrical main body portions 1 each having an axial length of 800 mm, 1200 mm, and 500 mm are prepared, and the main body portions 1 having the same axial length are combined to form a cylindrical shape. Then, three kinds of main body portions 1 may be laminated in the axial direction. Furthermore, the structure of the groove | channel 2 and the brush part 3 in three types of main-body parts 1 may differ at this time. If it does in this way, the suitable brush 10 according to the shape etc. of a to-be-cleaned body can be comprised. Further, the main body 1 may be cylindrical. In this case, the brush 10 can be assembled by feeding the brush part 3 into the groove 2 exposed on the end faces S3, S4. In addition, when a to-be-cleaned body is large and the brush 10 is enlarged, it is preferable that the brush stand of the brush 10 is comprised by the several main-body part 1 from viewpoints of assemblability. If it does in this way, after attaching the brush part 3 with respect to each main-body part 1, the large-sized brush 10 can be obtained easily by assembling the several main-body part 1 to which the brush part 3 was attached. .

  Moreover, in the brush which concerns on this Embodiment, although the bottom part of the groove | channel 2 has circular shape, it is not restricted to this. Referring to FIG. 7, for example, the bottom of groove 2 may have a square shape having a bottom side, and width W <b> 2 may be provided as the length of the bottom side. Even if it does in this way, it can prevent that the holder 6 slips out from the opening part of the groove | channel 2 to the outer peripheral side of the main-body part 1 by providing the holder 6 so that fitting to the groove | channel 2 is possible.

  Further, in the brush according to the present embodiment, the groove 2 is provided so as to extend along the axial direction of the main body 1, but is not limited thereto. Referring to FIG. 8, for example, the main body 1 may be provided so as to be inclined with respect to the axial direction. Even in this case, the brush portion 3 can be easily inserted into the groove 2 from the peripheral end surface S5 located at the end in the circumferential direction of the main body 1 provided in the end surfaces S3, S4 or the semicylindrical shape. . In addition, referring to FIG. 9, it may be provided so as to intersect perpendicularly to the axial direction of main body 1. Even if it does in this way, if the main-body part 1 is provided in semi-cylindrical shape, the brush part 3 can be easily inserted in the groove | channel 2 from the peripheral end surface S5 located in the edge part of the circumferential direction of the main-body part 1. FIG. Can do.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is shown not by the above-described embodiment but by the claims of utility model registration, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims of utility model registration.
