Description

  The present invention relates to a handle-equipped wiping tool in which a handle is attached to a wiping tool so as to be detachable and rotatable.

  It is well known that a wiping tool made of sponge, scrubbing, etc. has a handle attached so that it can be easily grasped and handled.

As shown in FIG. 8, as such a wiping tool 20 with a handle, an attachment shaft 25 is provided at the tip of the handle 24 so as to protrude in both directions of the handle 24, and a plate-like pedestal 22 is attached to the wiping tool 21. In some cases, a pair of bearings 23 projecting from the plate surface of the base 22 and receiving the mounting shaft 25 are provided (see FIG. 5 of Patent Document 1 and paragraphs 0002 and 0003).
As shown in the figure, shaft holes 23 a are formed in the opposing surfaces of the pair of bearings 23 of the wiping tool 21, and the gap between the bearings 23 is smaller than the shaft length of the mounting shaft 25 of the handle 24.

The handle 24 is attached to the wiping tool 21 by pressing the mounting shaft 25 made of plastic or the like against the outer surface of the bearing 23 to bend (elastically deformed). By fitting both ends of the shaft into the shaft hole 23a.
Similarly, the handle 24 is removed from the wiping tool 21 by bending the mounting shaft 25 and extracting both end portions from the shaft hole 23a.

  Thus, since the handle 24 is detachably attached to the wiping tool 21, when the wiping tool 21 is worn out, it is only necessary to remove the handle 24 and replace only the wiping tool 21, thereby wasting resources. Don't be.

  Furthermore, since the handle 24 is rotatable with respect to the wiping tool 21 about the attachment shaft 25, the attachment angle of the handle 24 to the wiping tool 21 can be adjusted as appropriate so that it can be easily held. The burden of work is reduced.

  However, in this type of wiping tool 20 with a handle, since the attachment shaft 25 is bent and deformed as described above, a large force is required every time the handle 24 is attached and removed, which is troublesome. is there.

Further, when fitting using the bending of the shaft 25 as described above, it is necessary to increase the bending amount to increase the fitting depth.
However, on the other hand, if the shaft 25 is bent excessively, the shaft or the like may not withstand the load and may be broken.
For this reason, in the wiping tool 20 with a handle, the depth of fitting is limited to a level at which the shaft 25 does not break due to bending, that is, substantially below a certain level.
If the fitting is shallow in this way, when the wiping tool 21 with the handle 24 is used, if the load is applied to the attachment portion of the handle 24 and the shaft is deformed, the fit between the shaft and the bearing 23 is easily removed. There is a problem that the attachment strength of the handle 24 to the wiping tool 21 is not sufficient.
Utility Model Registration No. 30673322

  Therefore, the problem to be solved by the present invention is to facilitate the attachment of the handle to the wiping tool and to improve the attachment strength of the handle to the wiping tool.

  In order to solve the above-described problems, the wiping tool and a handle attached to the wiping tool are configured, and the handle has a mounting shaft projecting in both directions at a tip portion thereof. The base is provided with a pair of bearings projecting from the plate surface, and a shaft hole is formed in each of the opposing surfaces of the pair of bearings, and the shaft of the mounting shaft is formed in the shaft hole. In the wiping tool with a handle of the present invention in which the handle is attached to the wiping tool so as to be detachable and turnable by fitting both ends, the following configuration is adopted.

  That is, a retaining piece is provided on the outer surface of the mounting shaft, and an insertion groove of the mounting shaft communicating from the bearing peripheral surface to the shaft hole is formed on each of the opposing surfaces of the bearing, so that the mounting angle of the handle with respect to the wiping tool is constant. When it is within the range, the mounting shaft can be inserted into the insertion groove, and when it is outside the predetermined range, the retaining piece prevents insertion of the insertion groove of the mounting shaft.

When configured in this way, from the state where the handle and the wiping tool are separated, the angle between the handle and the wiping tool is maintained in the above-mentioned fixed range, and when the insertion shaft is inserted into the insertion groove, the shaft hole is inserted as it is, It becomes possible to fit both ends of the shaft into the shaft hole.
In this case, since it is not necessary to apply a load to the shaft and bend it, no force is required and attachment is easy.

Similarly, unlike the method of bending the mounting shaft, since there is no restriction on the depth of fitting, the depth of fitting can be increased compared to the conventional case.
As described above, since the fitting depth can be increased, even if an external force is applied to the attachment portion and the shaft is slightly deformed, the handle is not detached from the wiping tool, and the attachment strength can be improved.

In addition, after fitting both ends of the mounting shaft into the shaft hole of the bearing, if the handle is rotated around the mounting shaft and the mounting angle between the handle and the wiping tool is out of the predetermined range, the retaining piece This prevents the shaft from passing through the insertion groove.
Therefore, if the attachment angle is kept outside the above-mentioned fixed range, the handle will not come off the wiping tool during use of the wiping tool with the handle.

The retaining piece is formed on the end surface of the mounting shaft, the insertion groove has a bottom, and a groove that communicates in the length direction of the groove is formed on the bottom of the groove. When the mounting shaft is inserted into the insertion groove in a face-to-face state, it is preferable that the retaining shaft fits into the recess and is guided in the groove length direction so that the mounting shaft can be inserted through the insertion groove. .
In this way, if the mounting shaft is rotated from the right-facing state and the retaining piece is shifted, the retaining piece will not fit into the groove, so that the retaining shaft will function as a non-insertion groove. It will be inserted.
Therefore, switching between insertion and non-insertion of the insertion groove of the mounting shaft can be realized with a simple structure.
And since the structure is simple in this way, the wiping tool with a handle is excellent in durability and the manufacturing cost is low.
Further, since the retaining piece is formed on the end surface of the mounting shaft, unlike the case where the retaining piece is formed on the side peripheral surface of the shaft, the rotation of the mounting shaft is not hindered and the turning of the handle is smooth.

In the state where a regular polygonal column-shaped, angle-adjustable part that is elastically deformable with the attachment shaft as the center is provided at the tip of the handle, and the handle is attached to the wiping tool, the circumferential surface of this angle adjuster and the plate surface of the base are When the rotational load is applied to the handle, the angle adjusting portion is elastically deformed and rotated, and the other peripheral surface adjacent to the one peripheral surface is in contact with the plate surface of the pedestal. If the attachment angle with respect to the wiping tool can be adjusted and fixed, the attachment angle adjustment and fixation of the handle can be realized with a simple structure.
If it does in this way, it can be cheap, it can fix to the angle which is easy to grasp a handle | strain suitably, and it will become easy to clean.

  Since the handle shaft and the insertion groove of the bearing are configured as described above, the handle can be easily attached to the wiping tool, and the attachment strength is improved.

  1 includes a wiping tool 11 and a handle 14 attached to the wiping tool 11. The wiping tool 11 is operated by holding the handle 14 so that the wiping tool 11 can be used in a bathhouse. Cleaning work is done by rubbing directly against the floor surface.

  As shown in FIGS. 1 to 3, the wiping tool 11 is composed of a sponge block having a substantially trapezoidal shape in plan view, and a flat plate-like pedestal 12 similar to the wiping tool 11 and having a slightly smaller size in plan view is attached to one surface thereof. ing.

Specifically, the pedestal 12 is provided with a pair of bearings 13 that protrude from the plate surface in a substantially vertical direction and face each other.
The bearing 13 is substantially semicircular in a side view, and a shaft hole 13 a having a bottom shape similar to the bearing 13 is formed on each of the opposing surfaces (inner side surfaces) of the bearing 13.

Similarly, in each of the opposing surfaces, a bottomed insertion groove 13b extending substantially parallel to the plate surface of the pedestal 12 communicates from the arcuate circumferential surface of the bearing 13 to the upper portion of the shaft hole 13a.
Here, the insertion groove 13b is bisected in the groove width direction, and the groove bottom on the side away from the pedestal 12 is recessed to form a recess 13c.
Here, the depth of the groove including the recess 13c is substantially the same as the depth of the shaft hole 13a, and the depth of the groove excluding the recess 13c is formed shallower than the depth of the shaft hole 13a.

In addition, between the pair of bearings 13, the plate surface of the pedestal 12 swells small, and the top portion is formed flat to form a flat plate-like contact table 12 a having a square shape in plan view.
The wiping tool 11 is formed by punching a sponge sheet (foamed resin sheet) into a trapezoidal shape in plan view, and the pedestal 12 and the bearing 13 are integrally formed of plastic.

Next, as shown in FIGS. 1 to 3, the channel-shaped handle 14 is provided with a grip 14 a at the rear end thereof, and a round shaft-like mounting shaft 15 protruding in the direction of both sides of the channel is provided at the front end. It is connected continuously.
In addition, the tip end portion of the handle 14 is formed in a regular polygonal column shape having the attachment shaft 15 as an axis to form an angle adjusting portion 14b, and when the handle 14 is attached to the wiping tool 11, the angle adjusting portion. The peripheral surface of 14b substantially comes into contact with the contact table 12a of the base 12.

  The mounting shaft 15 is divided into two equal parts in the thickness direction of the handle 14, and a retaining piece 15 a protruding in a semi-cylindrical shape is provided on the end surface of the handle 14 near the channel bottom surface.

Here, the diameter of the mounting shaft 15 is substantially equal to the groove width of the insertion groove 13b, and the shaft length including the retaining piece 15a of the mounting shaft 15 is the bottom of the recess 13c of the insertion groove 13b of the opposing bearing 13. The axial length excluding the retaining piece 15a of the mounting shaft 15 is substantially equal to the distance between the groove bottoms of the insertion grooves 13b of the bearing 13 facing each other.
The handle 14 and the mounting shaft 15 are integrally formed of plastic, so that the angle adjusting portion 14b made of plastic can be elastically deformed.

When attaching the handle 14 to the wiping tool 11, as shown in FIGS. 2 and 4, the channel bottom surface side of the handle 14 and the pedestal 12 of the wiping tool 11 are opposed to each other, and the handle 14 and the pedestal 12 are substantially parallel to each other. The mounting shaft 15 of the handle 14 is inserted into the insertion groove 13b of the wiping tool 11.
Then, since the retaining piece 15a on the shaft end face is in a state of facing the concave strip 13c of the insertion groove 13b having a complementary shape, the retaining strip 15a is fitted into the concave strip 13c and guided in the length direction of the groove. Then, the attachment shaft 15 is inserted through the insertion groove 13b to the shaft hole 13a.
And the handle | steering-wheel 14 is attached to the wiping tool 11 by the both ends of the attachment shaft 15 getting stuck in the shaft hole 13a.

Since the handle 14 is attached to the wiping tool 11 without bending the attachment shaft 15 in this way, no force is required and no labor is required.
Further, since the attachment shaft 15 is fitted into the shaft hole 13a through the insertion groove 13b, the depth of fitting can be increased as much as possible, and the attachment strength of the handle 14 to the wiping tool 11 can be improved.

When using the wiping tool 10 with a handle, it is preferable to rotate the handle 14 with respect to the wiping tool 11 by a certain angle from this state, with the attachment shaft 15 as the center, as shown in FIGS.
Then, since the above-described retaining piece 15a is deviated from the state of facing the concave strip 13c, the retaining piece 15a is caught and cannot be passed even if the attachment shaft 15 is passed through the insertion groove 13b.
In this way, the retaining piece 15a serves as a retaining member, so that the handle 14 does not come off the wiping tool 11.

Here, as described above, when the handle 14 is rotated by a certain angle, as shown in FIGS. 3 and 4, the circumferential surface of the angle adjuster 14 b at the tip of the handle 14 and the contact table 12 a of the base 12 are separated. From the abutted state, the angle adjusting portion 14b is elastically deformed by a rotational load, so that a transition is made from the adjacent other peripheral surface to the abutting table 12a in sequence.
Since the attachment angle of the handle 14 is fixed in a state where the peripheral surface of the angle adjusting unit 14b is in contact with the contact table 12a, the attachment angle can be fixed in each of the above states.
In this manner, the fixed attachment angle can be changed by the rotation of the handle 14.
For this reason, the handle attachment angle can be arbitrarily adjusted and fixed with such a simple structure.

  In this embodiment, the retaining piece 15a is a semi-cylindrical convex portion provided on one end face of the mounting shaft 15, but the shape, position, number, etc. of the retaining pieces 15a are not limited thereto.

For example, as shown in FIG. 5, the retaining piece 15a may be a ridge that passes through the center line of the mounting shaft end face.
In this case, as shown in the figure, when the concave strip 13c is provided at the center in the width direction of the insertion groove 13b, the handle 14 and the pedestal 12 are parallel, and the mounting shaft 15 is inserted into the insertion groove 13b, the concave strip 13c. The protrusions 15a that are parallel to the protrusions 15a are guided in the recesses 13c.
Further, when the handle 14 is rotated after the attachment, the retaining piece 15a is displaced from a position parallel to the concave strip 13c to prevent the retaining piece 15a from coming off.

Further, as shown in FIG. 6, the retaining piece 15 a may be a hemispherical convex portion provided in an eccentric state on the end surface of the mounting shaft 15.
As shown in the figure, when the handle 14 and the pedestal 12 are parallel, the hemispherical retaining piece 15a is guided by being caught in the recess 13c.
Further, when the handle 14 is rotated after the attachment, the retaining piece 15a is displaced from the position facing the concave strip 13c and becomes the retaining member.
Further, in this case, a plurality of retaining pieces 15 a may be arranged in parallel on a straight line passing through the axis of the attachment shaft 15.
At that time, in a state where the parallel direction of the retaining pieces 15a and the extending direction of the recess 13c of the insertion groove 13b coincide with each other, the mounting shaft 15 can be inserted through the insertion groove 13b, and is shifted from the directly-facing position. It will prevent slipping.
Such a retaining piece 15a may have a cylindrical shape, a prismatic shape, or the like.

Alternatively, as shown in FIG. 7, the position where the retaining piece 15 a is provided is not limited to the end surface of the attachment shaft 15, and may be provided on the side peripheral surface of the attachment shaft 15, for example.
In this case, it is not necessary to provide the recess 13c in the insertion groove 13b, and the insertion groove 15b can be inserted by inserting the attachment shaft 15 with the retaining piece 15a facing the insertion groove 13b.
Further, when the mounting shaft is rotated as shown in the figure from this state, the retaining piece 15a is prevented from coming off and insertion is prevented.

  Note that the retaining pieces 15a may not be provided on the attachment shafts 15 on both sides protruding from the tip of the handle 14 on both sides, and may be provided only on the attachment shaft 15 on one side.

In the embodiment, the entire pedestal 12 and the handle 14 are made of plastic, but the material is not limited to this, and may be made of metal, wood, or the like.
However, when a hard material is used as a whole, only the angle adjusting portion 14b may be formed of another material that can be elastically deformed.
In the embodiment, the wiping tool 11 is made of sponge. However, the wiping tool 11 is not limited to this, and may be a scrubbing cloth, a nonwoven fabric, or the like.
