Description

[Detailed description of the invention] The present invention molds the handle body and the brush body separately, and the engagement between the two is achieved by the engagement between the projection provided on the handle and the engagement hole provided on the brush body. The present invention relates to a brush configured to allow the user to engage the user with ease, and which is characterized in that the engagement is extremely secure and the occurrence of unexpected disengagement is avoided.

When it comes to bath brushes, it is desirable to have a long handle when washing the back, and when washing the lower back, etc., it is desirable to have a long handle which makes it difficult to wash, and it is also difficult to wash the tips of the hands and feet. In some cases, it is easier to wash without a handle. However, among conventional brushes, there are no brushes with such diversity, and it goes without saying that when three types of brushes are available, their management is extremely complicated.

The present invention solves the above-mentioned problems well, allows extremely diverse uses, and is constructed so as to be optimal not only as a bath brush but also as an industrial cleaning brush, and the brush body and handle are This is intended to significantly improve bonding properties.

Hereinafter, the configuration of the present invention will be explained in detail with reference to the drawings.

In the figure, reference numeral 1 denotes a brush body with a bristle-stamped body 2 fixed on the front and a short handle 1a integrally connected to the lower edge. A vertical groove 1b for fitting the handle body is vertically provided in the shape of a blind hole so as to penetrate through the shaped portion 1a. Reference numerals 3 and 4 are first and second engagement holes formed on the back of the brush body 1 near the terminal end and the beginning end of the vertical groove 1b for inserting the handle body, respectively, and these holes are used to lock the handle body 5 as described below. It is meant to be done. Furthermore, the edges of the first and second engagement holes 3 and 4 are tapered edges that become smaller in diameter as they go inward.

Reference numeral 5 denotes a handle body having an elastic engagement piece 6 formed at the tip thereof to be engaged with the first engagement hole 3 or the second engagement hole 4, and the elastic engagement piece 6 is attached to the handle body. By notching the distal end of 5 in an inverted U shape, an elastic piece 6a whose base end is connected to the handle body 1 is formed, and a protrusion 6b is formed at the distal end of the elastic piece 6a.
The shape of the protrusion 6b is such that it can be structurally engaged with the first and second engagement holes 3 and 4. Further, the protrusion 6b normally projects slightly from the outer surface of the handle 5, and the protrusion 6b is configured to be retracted into the inner surface of the handle 5 by pressing it with a finger. There is. Furthermore, a groove 6c is formed in the lower half of the periphery of the proximal end of the protruding portion 6b, so that when the handle body 5 is pulled in the pulling direction, the groove 6c The engaging holes 3 and 4 are configured so that the tapered hole edges are bitten into the engaging holes 3 and 4.

Reference numeral 7 is a through hole drilled in the lower end of the handle 5, which is used to hang the brush of the present invention on a hook rod or the like when storing it.

The present invention has the above-mentioned configuration, and normally the handle 5 is attached as shown in FIGS. 1 and 2.
The tip of the handle is inserted into the vertical groove 1b in the brush body 1.
The protrusion 6b of the elastic engagement piece 6 is stopped in the second engagement hole 4 for use.

Next, if you want to shorten the handle 5, press the protrusion 6b to separate it from the second engagement hole 4, and insert the handle 5 into the vertical groove 1b of the brush body 1. When it is fully inserted, the protrusion 6b of the elastic engagement piece 6 will lock into the first engagement hole 3 as shown in FIG. It becomes stable in a shortened state.

Furthermore, if the handle 5 is unnecessary, the protrusion 6b
If the handle body 5 is pulled while being pressed and disengaged from the first or second engagement holes 3, 4, the brush body 1 can be removed as shown in FIG.
It will also be permitted to use it alone. In this case, by grasping the short handle portion 1a connected to the brush body 1, its handling becomes extremely convenient.

Further, in the state shown in FIG. 2 or FIG. 7, if the handle 5 is strongly pulled without pressing the protrusion 6b of the handle 5, the tapered hole edge of the engagement hole 3 or 4 is bitten into the groove 6c of the protrusion 6b (see FIG. 8), so the handle body 5 is effectively prevented from coming off unexpectedly.

According to the present invention described in detail above, the length of the handle body can be adjusted in two stages, long and short, and the handle body 5 can be removed to allow use of the brush body 1 alone.
Moreover, such a change operation is very convenient as it only requires a one-touch operation of pressing the elastic engagement piece 6. Therefore, the present invention can be used not only as a bath brush but also as an industrial cleaning brush. Sexuality is extremely high quality. The number of engagement holes provided in the brush body 1 in the present invention may be adjusted in multiple stages, other than two as shown in the figure, three or more, or one in the handle. It is also possible to implement a configuration in which only the attachment and detachment of 5 is permitted.

Further, in the present invention, the engagement hole provided in the brush body 1 is provided with a tapered hole edge, and the lower half of the proximal periphery of the protruding portion 6b of the handle body 5 is provided with the tapered hole. Since the groove 6c is formed in a substantially semicircular shape so that the edge can be bited into, when a strong tensile force and warping force are applied to the handle 5, the tapered hole edge of the engagement hole is difficult to tighten. Therefore, the worry that the handle body 5 will come off inadvertently is completely eliminated, and after all, the problem of unexpected detachment of the handle body 5 when using the brush is completely eliminated.
