Description

  The present invention relates to a deck brush used for cleaning a kitchen floor, a bathroom floor, a pool bottom, or the like, a mop, a floor wiper, or glass used for cleaning a building floor (flooring). The present invention relates to a cleaning tool with a handle having a structure in which a handle is attached to a cleaning head, such as a draining wiper suitable for removing water droplets adhering to a surface or water on a floor surface.

  The deck brush, which is an example of this type of handle-equipped cleaning tool, for example, as described in Patent Document 1, for example, a cleaning head in which fibers for rubbing are implanted on the lower surface of a base elongated in one direction; It consists of a handle attached to the upper surface of the base in an obliquely upward direction, and is used for cleaning the floor of a kitchen, the floor of a bathroom, the bottom of a pool, and the like.

  However, in the conventional deck brush, since the cleaning head is mounted in a direction orthogonal to the handle and the direction cannot be changed, there is no particular problem when cleaning a wide flat portion of the floor. When cleaning the inside of the narrow drainage groove on the floor while moving the cleaning head along this groove, or when cleaning the peripheral part of the drainage port or the narrow edge part, it is very There was a drawback that it was difficult to work. For this reason, the appearance of a deck brush that can change the direction of the cleaning head in at least two directions, that is, a left-right direction and a front-rear direction, is desired.

  On the other hand, some mops and flooring wipers which are other examples of the cleaning tool with a handle can freely change the direction of the cleaning head. For example, Patent Document 2 discloses a flooring wiper-type cleaning tool that can freely change the direction of the cleaning head forward and backward and left and right as described above. However, in such a conventional cleaning tool, there is no particular problem even if the pattern orientation or angle changes when the cleaning head is pressed lightly against the floor surface, but the cleaning head is to be cleaned with a certain amount of force. In the case of pressing against the part, it is difficult to use if the handle tilts freely.

There are some that fix the handle and cleaning head in the required direction with fastening means such as thumbscrews and fixing means such as bolts and nuts, but the former uses the frictional force when tightening the thumbscrews etc. In this method, since a sufficient fixing force cannot be obtained, the cleaning head may be rotated by a force applied during work. In the latter method using bolts and nuts, since a plurality of bolts and nuts must be attached and detached each time the direction of the cleaning head is changed, the operation is very troublesome.

  The problem of the present invention is that it is possible to easily change the direction of the cleaning head in accordance with the object to be cleaned, the cleaning situation, etc., and to firmly fix the cleaning head in any direction, which is superior in usability. It is to provide a cleaning tool with a handle.

In order to solve the above problems, a cleaning tool with a handle according to the present invention includes a cleaning head having an elongated shape in one direction for cleaning a portion to be cleaned, a handle attached obliquely upward to the cleaning head, An attachment mechanism for attaching a handle to the cleaning head, and the attachment mechanism includes a base side connecting portion formed on a head base of the cleaning head, and a handle side formed on a tip portion of the handle. The base-side connecting portion includes a first ridge extending in the length direction of the head base and a second ridge extending in the width direction of the head base. , is formed in a shape combined in a cross shape, the said handle-side connecting portion with respect to this, a first groove extending through the該柄side connecting portion in the lateral direction, in the longitudinal direction該柄side connecting portion a second groove extending through is formed in a shape combined in a cross shape, these first groove portion及By selectively fitting the second groove portion and the first protrusions and the second protrusions, the cleaning head, the first position and the front and rear longitudinal axis is oriented in the lateral direction of the handle The direction can be changed to a second position facing the direction, and the handle-side coupling portion is divided into a first portion and a second portion at the position of the first concave groove portion, thereby opening and closing the first concave groove portion. The tip of the handle is connected to the first part, and a lever is connected to the second part. The lever is displaced by this lever to split the first groove. By opening, the connection between the base-side connecting portion and the handle-side connecting portion can be released, and both outer side surfaces of the first and second protrusions of the base-side connecting portion are respectively A locking recess is formed, and on the other hand, the first concave portion and the second portion of the handle side connecting portion are provided with the first concave groove portion and the second concave portion. A locking convex portion that can be freely engaged with and disengaged from the locking concave portion is formed on the opposite groove edge portion of the first concave groove portion of the second concave groove portion, and further, between the lever and the tip end portion of the handle. Is characterized in that a spring for biasing the first portion and the second portion toward the closing direction is interposed .

In the present invention, the handle-side connecting portion is formed of a synthetic resin, the locking projection is formed of a metal plate, and the metal plate bent into an L shape is the end serving as the locking projection. It is desirable that the portion is embedded in the handle side connecting portion in a state where the portion protrudes into the first groove portion.

  Further, in the present invention, the first portion and the second portion of the handle side connecting portion are connected so as to be rotatable by a support shaft orthogonal to the handle, and the lever is used to connect the second portion to the support shaft. The first concave groove portion can be freely opened and closed by pivoting around.

  According to the cleaning tool with a handle of the present invention, the direction of the cleaning head can be changed between the first position facing the left-right direction of the handle and the second position facing the front-rear direction of the handle. The cleaning head can be fixed in an easy-to-use direction and cleaning can be performed. In addition, since the protrusions and the concave grooves formed in a cross shape are provided on the cleaning head side and the handle side, and they are selectively fitted to each other, the two positions can be fixed easily. With a simple mounting mechanism, a very large fixing force can be obtained. Even when working with a certain amount of force, the direction of the cleaning head does not change or the angle of the handle does not change. It is. Furthermore, since the cleaning head and the handle can be separated and fixed in a required direction only by operating the lever, the direction changing operation is very easy.

  FIGS. 1-8 shows the 1st Example of the cleaning tool with a pattern which concerns on this invention, The cleaning tool 1A of this 1st Example is comprised as a deck brush. The cleaning tool 1A includes a cleaning head 3, a handle 4 attached to the cleaning head 3 obliquely upward, and an attachment mechanism for connecting the handle 4 and the cleaning head 3 so that the direction can be changed. 5.

  The cleaning head 3 is formed by implanting a large number of synthetic resin fibers 11 on the lower surface of a substantially rectangular head base 10 elongated in one direction. As a result, a flat hair tip surface 11a having a wider area than the head base 10 is formed. However, this hair end surface 11a may be formed in a waveform. Moreover, since the fiber 11 is used for scrubbing the kitchen floor, bathroom floor or pool bottom with a large force, it has waist strength and rigid elasticity sufficient to withstand it. A hard fiber 11 is desirable. The head base 10 is made of wood or synthetic resin.

  On the other hand, the handle 4 includes a straight rod-shaped handle body 20 made of a wooden bar, a synthetic resin pipe, a metal pipe, or the like, and a synthetic resin attachment member 21 connected to the tip of the handle body 20. Thus, the mounting mechanism 5 formed on the mounting member 21 and the head base extends on the upper surface of the head base 10 so as to be inclined obliquely upward from the head base 10. It is attached.

  The cleaning head 3 is attached to the handle 4 in the front-rear direction with respect to the first position in FIG. 1 in which the longitudinal axis of the cleaning head 3 faces in the left-right direction with respect to the axis of the handle 4 and the axis of the handle 4. It can be changed to two positions, the second position of FIG. In other words, in the first position, the longitudinal axis of the cleaning head 3 and the axis of the handle 4 are located in a plane perpendicular to each other, and in the second position, the longitudinal direction of the cleaning head 3 And the axis of the handle 4 are located in the same plane. Thus, in order to make it possible to change the direction of the cleaning head, the mounting mechanism 5 has a configuration as described below.

  That is, a base side connecting portion 12 constituting a part of the mounting mechanism 5 is formed at the center of the upper surface of the head base 10 of the cleaning head 3. The first and second protrusions 13 and 14 combined in a shape direct the first protrusion 13 in the length direction of the head base 10, and the second protrusion 14 is the head base. It is formed in a state facing 10 width directions. These ridges 13 and 14 have the same length as each other, and the length is substantially the same as or slightly shorter than the width of the head base 10. And the locking recessed part 15 is formed in the position except the part which these both protrusions cross | intersect near the lower end part of both the outer surface of the said 1st protrusion part 13 and the 2nd protrusion part 14, respectively. Has been. These locking recesses 15 are formed by grooves cut on the outer surfaces of the protrusions 13 and 14. The protrusions 13 and 14 have a U-shaped cross-sectional shape with a rounded top surface, but may have a square cross-sectional shape with a flat top surface.

  On the other hand, the attachment member 21 at the tip of the handle 4 cooperates with a cylindrical connection portion 22 for inserting and connecting the tip of the handle body 20 and the base side connecting portion 12 of the cleaning head 3. Thus, a handle-side connecting portion 23 constituting the mounting mechanism 5 is formed. The handle-side connecting portion 23 has a slightly horizontally long rectangular block shape, and its horizontal length, that is, the length along the left-right direction of the handle 4, is longer than the vertical length, ie, the length along the front-rear direction of the handle 4. Is also formed long. Then, on the lower surface of the handle-side connecting portion 23, first and second groove-shaped concave grooves 24 and 25 combined in a cross shape are formed so that the first concave groove portion 24 is orthogonal to the axis of the handle 4 The second concave groove portion 25 is formed in the extending direction of the handle 4, that is, in the front-rear direction of the handle. Accordingly, the length of the first groove portion 24 is the same as or slightly shorter than the length of the protrusions 14 and 15, and the length of the second groove portion 25 is shorter than that.

  Further, the handle-side connecting portion 23 is divided into a first portion 23a on the proximal end side and a second portion 23b on the distal end side at the center position of the groove bottom of the first concave groove portion 24, and the first portion 23a among them. Is connected to a connecting portion 22 which is a tip portion of the handle 4, and a lever 28 extending along the handle 4 is connected to the other second portion 23 b. The lever 28 is inclined with respect to the handle 4 in a direction in which a tip end portion is gradually separated from the handle 4. Then, both the parts 23a and 23b are connected so as to be openable and closable by a support shaft 29 at positions of bearing parts 28a and 22a formed on the lever 28 and the connecting part 22, respectively, as shown in FIG. By grasping the lever 28 and rotating it toward the connecting portion 22, the second portion 23b can be separated from the first portion 23a and the first concave groove portion 24 can be split into two. ing. Further, as can be seen from FIG. 5, a spring 30 is provided around the support shaft 29 at the position of the bearing portions 22a, 28a, and both ends of the spring 30 abut against the lever 28 and the connecting portion 22. The first portion 23a and the second portion 23b are in contact with each other via the lever 28, that is, the contact portions 23c and 23c are in contact with each other so that the first concave groove portion 24 is properly connected. It is urged toward the direction of keeping the groove shape.

  The left and right groove edge portions of the first groove portion 24 are stretched laterally toward the inside of the groove, except for the crossing portion with the second groove portion 25 (the portion where the second groove portion 25 crosses). Locking projections 26a and 26b are formed. These locking projections 26a and 26b are formed at positions where the first portion 23a and the second portion 23b face each other, and the first concave groove portion 24 and the first protrusion 13 or the second portion. When the protrusion 14 is fitted, the locking protrusions 26a and 26b engage with the locking recesses 15 and 15 of the protrusion, and the first groove 24 and the first protrusion 13 are engaged. Alternatively, the second protrusion 14 is fixed in a fitted state. As shown in FIG. 4, the engagement of the locking projections 26a and 26b and the locking recesses 15 and 15 is achieved by separating the second portion 23b from the first portion 23a by the lever 28, as shown in FIG. It can be canceled by splitting.

  The locking projections 26a and 26b are formed by end portions of the metal plates 27a and 27b having high strength. When the mounting member 21 is formed of synthetic resin, the metal plates 27a and 26b are bent into an L shape. 27b is formed by embedding it in the resin in a state where the end portions to be the locking convex portions 26a and 26b protrude into the first concave groove portion 24. In addition, although the same latching convex part may be provided also in the groove edge part of the said 2nd concave groove part 25, in changing the direction of the cleaning head 3 so that it may mention later, the pattern side connection part 23 and When attaching and detaching the base-side connecting portion 12, it is necessary to devise so that the locking convex portion of the second concave groove portion 25 does not get in the way.

  When the cleaning tool 1A having the above-described structure is used to clean a relatively wide surface portion such as a portion to be cleaned, such as a kitchen floor, a bathroom floor, or a pool bottom, as shown in FIG. It attaches to the 1st position orthogonal to 4 and cleans in that state. At this time, the handle 4 and the cleaning head 3 are the first groove portion 24 and the second groove portion 25 of the handle-side connecting portion 23 and the first protrusion portion 13 and the second protrusion portion of the base-side connecting portion 12. 14 and the locking projections 26a and 26b of the first concave groove 24 are locked to the locking recesses 15 and 15 on both outer side surfaces of the first protrusion 13, thereby cleaning the cleaning head. It is in a state of being fixed very firmly both in the direction in which the direction 3 changes and in the direction in which the inclination angle of the handle 4 changes. For this reason, even if the cleaning head 3 is pressed against the portion to be cleaned with a very strong force, for example, a force many times that of a mop, the inclination angle of the handle 4 changes or the direction of the cleaning head 3 changes. There is no such thing.

  Further, when cleaning the narrow groove of the drainage groove provided on the floor, or when cleaning the peripheral portion of the drainage port, the narrow edge portion, etc., the cleaning head 3 is illustrated from the first position. 7 is changed to the second position along the extending direction of the handle 4 and cleaning is performed in that state. The attachment position at this time is changed as follows.

  That is, as shown in FIG. 4, the lever 28 is firmly grasped and rotated toward the connecting portion 22 against the biasing force of the spring 30, and the second portion 23b of the handle side connecting portion 23 is moved to the first portion 23a. The first concave groove portion 24 is split open by separating the first convex groove portion 24, and the locking convex portions 26 a and 26 b are detached from the locking concave portions 15 and 15 on both sides of the first protruding strip portion 13, thereby Separate from the base-side connecting portion 12. Then, the direction of the cleaning head 3 is changed by 90 degrees toward the second position shown in FIG. 7, and the first portion 23a is applied to one side surface of the second protrusion 14, and the locking protrusion 26a is disposed. Engage with one of the locking recesses 15 and release the lever 28 in this state. Then, the second portion 23b is displaced to the first portion 23a side by the urging force of the spring 30 and comes into contact with the side surface on the opposite side of the second protrusion 14, and the locking projection 26b is locked to the locking recess 15. Therefore, the first concave groove portion 24 is closed in a groove shape and is fitted and locked to the second protrusion 14. Further, the second groove portion 25 is fitted to the first protrusion 13. As a result, the handle 4 and the cleaning head 3 are firmly fixed to the second position.

  Therefore, even if the cleaning head 3 is pressed against the object to be cleaned with a strong force, the inclination angle of the handle 4 and the direction of the cleaning head 3 do not change. Moreover, since the lever 28 can be directly gripped by hand and the direction of the cleaning head 3 can be changed, there is no need to use a tool such as a wrench as in the case of fixing with bolts and nuts. It can be done easily and quickly.

  FIGS. 9-16 shows 2nd Example of this invention, and the cleaning tool 1B with a pattern of this 2nd Example is the water which has collected or adhered to to-be-cleaned parts, such as a floor surface and glass. It is the example comprised as a draining wiper which scrapes and removes. Therefore, in this cleaning tool 1B, the form of the cleaning head 3 is different from the cleaning tool 1A of the first embodiment, and the configuration of the attachment mechanism 5 is also partially different in relation thereto. In the following, the different parts will be mainly described.

  The cleaning head 3 of the cleaning tool 1B is configured by attaching a plate-like spatula member 11 made of an elastic material to a head base 10 that is narrow and long and narrow. The head base 10 is formed of synthetic resin so as to have an inverted U-shaped cross section, and the width W thereof is smaller than the height H. The spatula member 11 is made of an elastic material such as a sponge body (synthetic resin foam), a synthetic resin plate, or a rubber plate, and has a height D larger than a width (thickness) T and is higher than the height D. Is formed in a horizontally long rectangular shape having a large length L, and its upper end is fitted into the U-shaped groove 10a of the head base 10 and fixed to the head base 10 with a plurality of screws 17, and the spatula member 11 The lower end of the head extends downward from the head base 10. The spatula member 11 is formed to be slightly longer than the head base 10, and when it is attached to the head base 10, both end portions thereof protrude sideways from the head base 10. Yes.

  Here, the cleaning tool 1B is a relatively large draining wiper that drains a kitchen floor, a bathroom floor, or the bottom of a pool by applying a certain amount of force with both hands. In some cases, it is desirable that the spatula member 11 is formed of a relatively rigid material having a certain thickness as shown in the figure, and is handled with one hand for removing water droplets such as glass. In the case of a small-sized water draining wiper, it is desirable that the spatula member 11 is made of a flexible material and has a thin tip portion and a flexible structure.

  As in the case of the first embodiment, the base side connecting portion 12 formed at the center of the upper surface of the head base 10 in the cleaning head 3 has a first and second two combined in a cross shape. The two ridges 13, 14 are formed with the first ridge 13 directed in the length direction of the head base 10 and the second ridge 14 directed in the width direction of the head base 10. Yes. However, the lengths of the protrusions 13 and 14 are not the same as each other, the second protrusion 14 is formed shorter than the first protrusion 13, and the length of the protrusions 13 and 14 is the same as that of the head base 10. It is almost the same as the width W or slightly longer than that. The reason for forming the second ridge 14 short in this way is that if the length of the second ridge 14 is too long, both ends of the second ridge 14 protrude greatly on both sides in the width direction of the head base 10, and during draining cleaning. This is because it tends to interfere with the work due to contact with the wall, etc. For this reason, it is formed as short as possible within a range in which the connection strength with the handle 4 can be secured. One first protrusion 13 is not particularly limited in length, and is formed to a required length within a range in which sufficient connection strength can be secured.

  And the locking recessed part 15 is located in the position except the part which these two protrusion parts 13 and 14 cross | intersect near the lower end part of both the outer surface of the said 1st protrusion part 13 and the 2nd protrusion part 14. Each is formed. Among these, the locking recesses 15, 15 of the first protrusion 13 are formed by grooves cut on both side surfaces of the first protrusion 13, and the locking recesses 15, 15 of the second protrusion 14 are formed. Is formed by a step portion formed at the lower end portion of the second protrusion 14. However, the locking recesses 15 of the second protrusion 14 can also be formed by grooves provided on the side surfaces thereof.

  The protrusions 13 and 14 may have a substantially U-shaped cross-sectional shape with a rounded top surface or may have a square cross-sectional shape with a flat top surface. Further, these protrusions 13 and 14 may be hollow or solid.

  In the figure, 18 is a reinforcing rib formed on the upper surface of the head base 10, extending from both sides of the first protrusion 13 and extending toward both ends of the head base 10, and gradually. It disappears on the way as the height decreases. The rib 18 prevents the central portion of the head base 10 from being deformed when the working force from the handle 4 acts on the central portion of the elongated head base 10 at the time of draining cleaning. It is.

  On the other hand, as in the case of the first embodiment, the handle side connecting portion 23 formed on the attachment member 21 at the tip of the handle 4 has a slightly horizontally long rectangular block shape as a whole, and its lateral length ( The length along the left and right direction of the handle 4) is longer than the length in the vertical direction (the length along the front and rear direction of the handle 4), and two groove-shaped first concave grooves 24 combined in a cross shape on the lower surface thereof; The second groove portion 25 is formed with the first groove portion 24 directed in the left-right direction of the handle 4 and the second groove portion 25 directed in the front-rear direction of the handle 4. Therefore, the length of the first groove portion 24 is longer than the length of the second groove portion 25, and the relationship between the length of the groove portions 24, 25 and the protrusion portions 13, 14 is the first groove portion. 24 is slightly shorter than the first protrusion 13 but slightly longer than the second protrusion 14, and the second recessed groove 25 is formed slightly shorter than the second protrusion 14.

  The handle-side connecting portion 23 is divided into a first portion 23 a and a second portion 23 b, and the first concave groove portion is obtained by rotating the second portion 23 b around the support shaft 29 by operating the lever 28. 24 can be split into two, and the first portion 23a and the second portion 23b are biased by the spring 30 in a direction to close each other. Same as example. However, the locking projections 26a and 26b formed on the first portion 23a and the second portion 23b are formed integrally with the first portion 23a and the second portion 23b with synthetic resin. However, this is different from the case of the first embodiment formed by using a metal plate. However, the locking projections 26a and 26b can be formed of a metal material as in the first embodiment.

  In addition, about the structure other than the structure mentioned above of the said 2nd Example and operation in changing the direction of the cleaning head 3 to a 1st position and a 2nd position, it is substantially the same as 1st Example. Therefore, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  Moreover, the cleaning tool with a handle of the present invention is not limited to the above-described deck brush or draining wiper, but a mop having a rag or yarn bundle attached to the head base, or a thin wiping sheet on the head base. Needless to say, a flooring wiper or the like that is used by attaching is also included in the category.
