Description

  The present invention relates to a cleaning tool and a cleaning device, for example, a cleaning tool pulled by a carriage, and a cleaning device that is self-running or manually operated, for example.

  As conventional cleaning tools, not only hand-made brooms, mops or rags, but also various types of semi-automated manual operations such as suction cleaners, polishers and electric cleaners are used. . Recently, the development of a cleaning machine that can automatically travel is progressing, and depending on the cleaning environment, it is also possible to perform unattended cleaning.

  Here, in the business-use cleaning machine in which the scale of the cleaning target becomes large, it is necessary to have a cleaning function corresponding to the size of the cleaning target, and thus the cleaning machine itself becomes large. Therefore, in the case of a cleaning machine that acquires its own position and performs unattended cleaning while looking at the surrounding environment, it is necessary to run a position at a certain distance from the wall side in terms of safety. For this reason, it is difficult to clean corner portions such as rooms and passages.

  Therefore, a method has been proposed in which a corner portion can be cleaned by attaching a mop or the like that protrudes from the cleaning machine separately from the traveling cleaning machine or carriage. In this type, because the mop protrudes from the running part, when there is an obstacle on the mop track, the mop avoids the obstacle, or the mop escapes when it hits the obstacle Is required.

  For example, Patent Document 1 proposes a configuration that takes into account the obstacle problem described above. Specifically, the cleaning tool is connected to a traveling unit (power vehicle) via a rod-shaped member, and is in a state of protruding from the traveling unit. The cleaning tool is attached to the end of the bar-like member opposite to the traveling portion side via a rotating shaft, is rotatable, and is given a restoring force by a spring.

  As a result, when the mop hits an obstacle, the mop rotates around the rotation axis so that the obstacle can be avoided. Further, when the obstacle disappears, the mop can return to the original state by the restoring force of the spring. Therefore, even if an obstacle exists on the traveling track of the mop, it can be cleaned while avoiding it.

JP 2004-344358 A (released on December 9, 2004)

  However, in the configuration described in Patent Document 1, the length of the rod-shaped member is increased so that the mop does not come into contact with the traveling portion when the mop rotates about the rotation axis, and a sufficient distance between the mop and the traveling portion. Secured. For this reason, especially when the floor surface near the wall surface is being cleaned, there is a risk that the rod-shaped member, which is the mop attachment portion, will come into contact with the wall surface and damage the wall unless the turning radius of the traveling unit is increased. is there. On the other hand, if the turning radius of the traveling part is increased, the traveling part cannot travel near the corners of the room, so that it becomes difficult to clean the corners of the room and the passage.

  Moreover, in the mechanism of Patent Document 1, since the mop is connected to the traveling unit by a bar-like member, a universal joint for holding the mop in parallel with the floor is also necessary. For this reason, two universal joints for vertical movement and rotation are required in one mop. Furthermore, the structure which gives a restoring force to a mop as mentioned above is also required. As a result, there is a problem that the configuration is complicated.

  Accordingly, an object of the present invention is to provide a cleaning tool and a cleaning device having a simple configuration in which corners of a room or a passage can be cleaned by reducing a radius of rotation near an obstacle such as a wall.

  In order to solve the above-described problem, a cleaning tool according to one aspect of the present invention intersects with a cleaning tool main body that is pulled and moves on a floor surface, and a direction in which the cleaning tool main body is pulled. It is connected to the cleaning tool main body at two connecting portions in the direction, and includes a deformable linear member for pulling the cleaning tool main body at the two connecting portions. It is said.

  According to one embodiment of the present invention, the radius of rotation near an obstacle such as a wall can be reduced to clean a corner of a room or a passage, and a simple configuration can be achieved.

It is an explanatory view showing another example of the cleaning device shown in FIG. 1 and showing an example in which two wires are individually connected to the traveling device by two attachment portions provided on the traveling device. .

[Embodiment 1]
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a schematic diagram showing a basic configuration of a cleaning device according to an embodiment of the present invention.

  As shown in FIG. 1, the cleaning device 1 of the present embodiment includes a traveling device 20 and a mop 10. The traveling device 20 may be a self-propelled type equipped with a drive source such as a motor or an engine, or a manual type driven manually. The traveling direction of the traveling device 20 in FIG. 1 is an arrow direction (↑ direction).

  The mop (cleaning tool main body) 10 has a shape that is long in the width direction of the traveling device 20, and is connected to the traveling device 20 by a wire (linear member) 11. That is, the mop 10 cleans the floor surface by being pulled and moved by the traveling device 20 via the wire 11. In this case, since the mop 10 is longer than the width of the traveling device 20, an area wider than the region through which the traveling device 20 passes can be cleaned. The wire 11 is deformable and can be bent. In the present embodiment, the mop 10 and the wire 11 constitute a cleaning tool. The wire 11 is not limited to a metal as a material, and includes various materials, and various shapes such as a string and a rope.

  The mop 10 has linear member attaching portions (connecting portions) 13a and 13b at positions equidistant from the longitudinal center of the mop 10 to one side and the other side in the longitudinal direction. One end of the wire 11 is fixed to the linear member mounting portion 13a, and the other end of the wire 11 is fixed to the linear member mounting portion 13b. Further, the central portion of the wire 11 is fixed to an attachment portion 12 provided at the rear end position of the traveling device 20. Therefore, the wire 11a reaching the attachment portion 12 from the linear member attachment portion 13a and the wire 11b reaching the attachment portion 12 from the linear member attachment portion 13b have the same length. The wires 11a and 11b are not limited to those using a single wire 11, and may be independent of each other.

  In the above configuration, when the traveling device 20 is moved forward, tension is applied to the wires 11a and 11b, and the mop 10 moves forward while being dragged by the traveling device 20. At that time, although a frictional force is applied to the mop 10, the center of the frictional force is near the center of the mop 10, that is, near the center of the linear member attachment portions 13a and 13b. Therefore, the mop 10 can always maintain a state in which the longitudinal direction is perpendicular to the traveling direction of the traveling device 20 (hereinafter simply referred to as a normal state).

  Next, the case where the obstacle 5 exists on the track of the mop 10 will be described. FIG. 2 is an explanatory diagram showing a state where the mop 10 collides with the obstacle 5 existing on the track of the mop 10 in the cleaning device 1 shown in FIG. 1. FIG. 3 is an explanatory diagram showing a state in which the mop 10 avoids the obstacle 5 from the state of FIG.

  As shown in FIG. 2, when the mop 10 collides with the obstacle 5 while the traveling device 20 is traveling, the mop 10 rotates with respect to the traveling device 20 so as to escape from the obstacle 5. In this case, the distance between the mounting portion 12 of the traveling device 20 and the linear member mounting portion 13a of the mop 10 is shortened on the side of the traveling device 20 where the obstacle 5 is not present (right side in FIG. 2). Therefore, the wire 11a is bent and the force for pulling the mop 10 is lost. Thereby, the mop 10 rotates counterclockwise around the linear member mounting portion 13b.

  When the mop 10 rotates in this manner, the reaction force is applied to the mop 10 and the wire 11b in the direction away from the obstacle 5, so that the mop 10 and the wire 11b move in the direction away from the obstacle 5 around the attachment portion 12 of the traveling device 20.

  When the traveling device 20 further advances from the state shown in FIG. 2, the obstacle 5 exists on the track of the mop 10, as shown in FIG. 5 is avoided. In this case, the mop 10 is subjected to a force that always tries to return to the direction orthogonal to the traveling direction of the traveling device 20 due to the frictional force with the floor surface. Therefore, the mop 10 travels so as to always press the corner of the mop 10 against the obstacle 5.

  Thereby, when the obstacle 5 (for example, a wall) exists in the track of the mop 10, the mop 10 always slides on the wall of the obstacle 5 (for example, the wall) while moving the floor surface of the wall of the obstacle 5 (for example, the wall). Can be cleaned.

  During traveling of the traveling device 20, that is, the mop 10, a force is always applied to the mop 10 to return to the normal state (the longitudinal direction is perpendicular to the traveling direction of the traveling device 20). Therefore, the mop 10 passes through the obstacle 5 and returns to the normal state when the obstacle 5 disappears.

  Here, FIG. 1 shows an example in which the two wires 11 a and 11 b are connected to the traveling device 20 by one attachment portion 12 provided in the traveling device 20. However, the two wires 11a and 11b may be individually connected to the traveling device 20 by the two attachment portions 12 provided in the traveling device 20 corresponding to the wires 11a and 11b.

  FIG. 8 is an explanatory diagram showing an example in which two wires 11 a and 11 b are individually connected to the traveling device 20 by two attachment portions 12 provided on the traveling device 20. In the example of FIG. 8, in the traveling device 20, the mounting part 12a is provided at a position facing the linear member mounting part 13a of the mop 10, and the mounting part 12b is provided at a position facing the linear member mounting part 13b. Yes. That is, the attachment portions 12a and 12b are provided at positions facing the linear member attachment portions 13a and 13b, respectively, in the width direction at the rear end portion of the traveling device 20, and the wire 11a is provided with the attachment portion 12a and the linear member attachment portion. The wire 11b is provided between the attachment portion 12b and the linear member attachment portion 13b.

  In the configuration shown in FIG. 1, since the two wires 11 a and 11 b are attached to the attachment portion 12 at one place, the entire cleaning tool including the wires 11 a and 11 b and the mop 10 is attached to the attachment portion 12. It becomes possible to rotate around. Therefore, the mop 10 can be easily avoided from the obstacle 5 as compared with the case where the attachment portion 12 is separated (for example, in the case of FIG. 8).

  In addition, when the traveling device 20 rotates at a wall or the like, the rear portion of the traveling device 20 does not have a fixed and projecting rearward structure portion (a fixed projecting structural portion connected to the mop 10). The traveling device 20 can smoothly rotate with a small turning radius.

  As described above, in the cleaning device 1 according to the present embodiment, when the obstacle 5 does not exist on the track of the mop (cleaning tool) 10, the floor surface can be cleaned while the mop 10 is kept in a normal state. it can. On the other hand, when the obstacle 5 exists on the track of the mop 10, the mop 10 can avoid the obstacle 5 and clean the floor surface as close to the obstacle 5 as possible.

  Moreover, the traveling device 20 can be easily rotated with a small turning radius even at the wall. Furthermore, since the traveling apparatus 20 does not require a rotating shaft, it has a simple configuration.

  Next, a specific example of the cleaning device 1 shown in FIG. 1 will be described. FIG. 4 is a schematic perspective view showing a cleaning device 110 that embodies the cleaning device 1 shown in FIG. 1.

  In the cleaning device 110 illustrated in FIG. 4, the mop 110 includes a plate-shaped support plate portion 110 a that is long in the width direction of the traveling device 120, and a cleaning unit (for cleaning the floor surface) is provided under the support plate portion 110 a. (Not shown).

  The cleaning device 110 is provided with a contact prevention rod 131 at the rear end portion of the traveling device 120, and a contact prevention rod 132 at the front end portion of the mop 110. The contact prevention rod 131 of the traveling device 120 is attached to a support plate 133 fixed at the rear end position of the traveling device 120. Further, the contact prevention rod 131 is located at a lower rear portion than the rear wheels 121 on both sides of the traveling device 120, extends in the width direction of the traveling device 120, and has a length reaching the outer end portions of the rear wheels 121 on both sides. doing.

  The contact prevention rods 132 of the mop 110 are attached to support members 134 fixed to both ends of the support plate portion 110a, extend in the longitudinal direction of the support plate portion 110a, and have the same length as the support plate portion 110a. ing. Further, the front end surface of the contact prevention rod 132 in the moving direction of the mop 110 (the traveling direction of the traveling device 20) is positioned forward of the front end surface of the support plate portion 110a of the mop 110, and the upper surface of the contact prevention rod 132 is supported. It is located at a position higher than the upper surface of the plate part 110a.

  In the cleaning device 110, the mounting portion 112 of the traveling device 120 is attached to the rear end portion of the traveling device 120 via the overload prevention portion 135. The overload prevention unit 135 includes a magnet and a magnetic member (magnetic body) to which the magnet is attracted, and when a certain force is applied to the mop 110, that is, the wire 111, the magnet and the magnetic member are disconnected. It has become. A specific example of the overload prevention unit 135 is such that, for example, a magnet is attached to the tip of the attachment portion 112 and the member on the traveling device 120 side to which the magnet is attracted is made of a magnetic material.

  The wires 111a and 111b and the linear member attaching portions 113a and 113b correspond to the wires 11a and 11b and the linear member attaching portions 13a and 13b shown in FIG.

  In the above configuration, the operation of the cleaning device 110 when the mop 110 collides with the obstacle 5 and the other detailed functions of the cleaning device 110 are the same as those of the cleaning device 1 described with reference to FIGS.

  In the cleaning device 110, the contact prevention rods 131 and 132 are provided so that the rear wheel 121 of the traveling device 120 and the support plate portion 110 a of the mop 110 are not in contact with each other. Thereby, when the mop 110 moves unexpectedly or when the traveling device 120 moves backward, it is possible to prevent the traveling device 120 from stepping over the mop 110. Therefore, the traveling device 20 can move backward stably without stepping over the mop 10.

  Moreover, since the attachment part 112 to which the wire 111 is connected is attached to the traveling device 120 via the overload prevention part 135 including a magnet and a magnetic member, a force of a certain level or more is applied to the mop 110, that is, the wire 111. When added, it is disconnected from the travel device 120. Accordingly, for example, it is possible to prevent a situation in which the mop 110 contacts the structure and an excessive force is applied to the mop 110, and the mop 110, the traveling device 120, or the structure with which the mop 110 contacts is damaged.

  In addition, the overload prevention part 135 is not limited to the structure provided with the magnet and the magnetic member, You may have a connection structure where a connection is cancelled | released when a fixed force or more is applied.

  In addition, the overload prevention unit 135 measures a force applied to the mop 110, a means for sending a stop signal (a signal for instructing a stop) to the traveling device 120 when a certain force is applied to the mop 110, and The structure provided with the means to stop the traveling apparatus 120 when the said stop signal is received may be sufficient.

  Moreover, in this Embodiment, the mop is demonstrated to the example as a cleaning tool (cleaning tool main-body part). However, the cleaning tool may be another conventionally known cleaning tool such as a brush, a cleaning pad, or a suction nozzle instead of the mop. This also applies to the cleaning devices of other embodiments.

  Further, in the present embodiment, a self-propelled traveling device 20 is provided, and it is possible to clean up to the corner of a room or a passage that has conventionally been difficult to clean with the configuration including the self-propelled traveling device 20. . However, in the configuration of the present embodiment, the self-propelled traveling device 120 is not a dedicated device, and a self-propelled device, for example, a carriage, for example, a mop 110 as a cleaning tool provided with the wire 111 is provided. The attached structure may be sufficient. This also applies to the configurations of the other embodiments.

[Embodiment 2]
Another embodiment of the present invention will be described below with reference to the drawings.
FIG. 5 is a schematic diagram showing a basic configuration of a cleaning device according to another embodiment of the present invention.

  As shown in FIG. 5, the cleaning device 2 of the present embodiment includes tension springs 71 (tension springs 71a and 71b) instead of the wires 11 (wires 111) as linear members. As described above, the configuration using the tension spring 71 instead of the wire 11 (wire 111) as the linear member can be similarly applied to the cleaning device 110 shown in FIG. The other structure in the cleaning apparatus 2 is the same as that of the cleaning apparatus 1 shown in FIG. 1 and the cleaning apparatus 110 shown in FIG.

  In the above configuration, in the cleaning device 2, when the traveling device 20 travels, the mop 10 is pulled by the traveling device 20 via the tension spring 71 and moves in the traveling direction of the traveling device 20. In this case, the tension spring 71 is in an extended state.

  When the mop 10 collides with the obstacle 5 from this state, the mop 10 is connected to the traveling device 20 by the tension spring 71, and similarly to the case where the mop 10 is connected to the traveling device 20 by the wire 11, FIG. And the operation | movement shown in FIG. 3 is performed. Here, for convenience, in FIGS. 2 and 3, the cleaning device 1 shown in each drawing is replaced with the cleaning device 2.

  In this case, the mop 10 is in contact with the obstacle 5 due to the frictional force with the floor surface and the restoring force of the tension spring 71b, and always moves while sliding on the fence of the obstacle 5. Thereby, the mop 10 can always clean the floor surface of the obstacle 5 (for example, wall) while sliding the fence of the obstacle 5 (for example, the wall).

  Further, since the linear member is the tension spring 71, the tension spring 71b on the side where the obstacle 5 is present among the tension springs 71a and 71b remains in the stretched state or is further stretched. On the other hand, the tension spring 71a on the side where the obstacle 5 does not exist is in a contracted state.

  Therefore, the tension spring 71 (the tension springs 71a and 71b) is difficult to come into contact with the floor surface, and it is possible to prevent a situation where the linear member, that is, the tension spring 71 is caught by some member or a soiled floor surface.

  In addition, when the rigidity of the tension spring 71 is increased, the mop 10 (the mop 110) and the traveling device 20 (the traveling device 120) do not approach each other. Therefore, in this case, the contact prevention rods 131 and 132 shown in FIG. 4 can be omitted.

  Other functions of the cleaning device 2 are the same as those of the cleaning devices 1 and 110 described above.

[Embodiment 3]
Still another embodiment of the present invention will be described below with reference to the drawings.
FIG. 6 is a schematic diagram showing a basic configuration of a cleaning device according to still another embodiment of the present invention.

  As shown in FIG. 6, the cleaning device 4 of the present embodiment includes a single wire 41 as a linear member, and the wire 41 is connected to the traveling device 20 via a pulley 45.

  Specifically, the pulley 45 is returned to its original position even when rotated by an elastic member such as a spring provided inside the pulley 45, for example. The wire 41 is attached so as not to shift its position with respect to the outer peripheral surface of the pulley 45, one end is fixed to the linear member attaching portion 13a, and the other end is fixed to the linear member attaching portion 13b.

  In the above configuration, the operation when the mop 10 collides with the obstacle 5 will be described below. Here again, for the sake of convenience, FIGS. 2 and 3 are used, and the cleaning device 1 shown in each drawing is replaced with the cleaning device 4.

  As shown in FIGS. 2 and 3, the mop 10 rotates with respect to the traveling device 20 so as to escape from the obstacle 5 when it collides with the obstacle 5. In this case, the mop 10 is in contact with the obstacle 5 due to the frictional force with the floor and the restoring force of the pulley 45, and always moves while sliding on the fence of the obstacle 5. Thereby, the mop 10 can always clean the floor surface of the obstacle 5 (for example, wall) while sliding the fence of the obstacle 5 (for example, the wall).

  When the mop 10 rotates, the side of the wire 41 that is in contact with the obstacle 5 is pulled out of the pulley 45, and the side that is not in contact with the obstacle 5 is wound around the pulley 45. Therefore, the wire 41 is not easily loosened even when the mop 10 rotates. Thereby, when the mop 10 rotates, the cleaning device 4 is less likely to cause a situation in which the wire 41 is loosened and caught on some member or the wire 41 is soiled.

  In the example shown in FIG. 6, the number of wires 41 as the linear member is one, but two wires 41 may be used and each may be fixed to the pulley 45.

  In addition, the structure of the cleaning apparatus 4 of this Embodiment is especially effective in the case of the structure provided with the traveling apparatus 20 which carries out automatic traveling. Moreover, the conventional cleaning machine can clean the corner of the room which cannot be cleaned by the conventional cleaning machine by including the cleaning tool of the present embodiment having the mop 10, the wire 41, and the pulley 45.

  Next, a specific example of the cleaning device 4 shown in FIG. 6 will be described below. FIG. 7 is a schematic perspective view showing a cleaning device 140 that embodies the cleaning device 4 shown in FIG. 4.

  In the cleaning device 110 illustrated in FIG. 7, the mop 110 has the same configuration as the mop 110 illustrated in FIG. 4 and includes a contact prevention bar 132.

  The pulley 145 is rotatably attached to a support member 146 provided at the rear end portion of the traveling device 20 by a shaft member 147. The shaft member 147 is provided with a torsion spring (not shown), and a restoring force acts on the pulley 145 by the torsion spring. The pulley 145 is provided with a wire connecting portion 148 to which the wire 141 is fixed. Further, the pulley 141 is provided with a wire 141 and a groove for preventing the displacement of the arranged wire 141.

  In the cleaning device 140, two wires 141 as linear members are provided, and one end of each of the two wires 141a and 141b is fixed to the wire connecting portion 148, and the other end thereof is a linear member attaching portion 113a, It is fixed to 113b.

  The operation of the cleaning device 140 configured as described above is as described with reference to FIG.

[Summary]
The cleaning tool according to one aspect of the present invention includes a cleaning tool main body (mop 10) that is pulled and moves on the floor surface, and two points in a direction that intersects the direction in which the cleaning tool main body is pulled. A deformable linear member that is connected to the cleaning tool main body at connecting portions (linear member attaching portions 13a and 13b) and pulls the cleaning tool main body at the two connecting portions. It is the composition which is.

  According to said structure, since the cleaning tool is provided with the linear member which can deform | transform the cleaning tool main-body part and the cleaning tool main-body part, it has become a simple structure.

  Further, the cleaning tool main body is pulled at two points via a deformable linear member when it collides with an obstacle (for example, a wall) during traveling (moving) for cleaning the floor surface. Therefore, it can rotate to escape from the obstacle. In addition, since the cleaning tool main body part is subjected to a force to return to the direction orthogonal to the traveling direction by the frictional force with the floor surface, the cleaning tool main body part always keeps the corner of the cleaning tool main body part against the obstacle. Drive as if pressing the part.

  Thereby, when an obstacle (for example, wall) exists in the track of the cleaning tool main body, the cleaning tool main body can always clean the floor surface of the obstacle heel while sliding on the obstacle heel. Therefore, the corner of the room or the passage can be cleaned by reducing the radius of rotation in the vicinity of an obstacle such as a wall, and a simple configuration can be achieved.

  Moreover, the cleaning tool which concerns on 1 aspect of this invention WHEREIN: The said linear member consists of two linear members, The one end part of the 1st linear member of these two linear members is the said, It is good also as a structure connected with the 1st connection part of two connection parts, and the one end part of a 2nd linear member connected with the 2nd connection part.

  According to said structure, the cleaning tool main-body part can deform | transform 1st and 2nd linear shape when it collides with an obstruction (for example, wall) during driving | running | working (moving) for the cleaning of a floor surface. Since it is pulled at two points through the member, it can rotate so as to escape from the obstacle. In addition, since the cleaning tool main body part is subjected to a force to return to the direction orthogonal to the traveling direction by the frictional force with the floor surface, the cleaning tool main body part always keeps the corner of the cleaning tool main body part against the obstacle. Drive as if pressing the part.

  Thereby, when an obstacle (for example, wall) exists in the track of the cleaning tool main body, the cleaning tool main body can always clean the floor surface of the obstacle heel while sliding on the obstacle heel.

  Moreover, the cleaning tool which concerns on 1 aspect of this invention WHEREIN: The said linear member consists of two tension springs, and the one end part of the 1st tension spring of these two tension springs is said 2 points | pieces. It is good also as a structure connected with the 1st connection part of the connection parts, and the one end part of the 2nd tension spring connected with the 2nd connection part.

  According to said structure, when a cleaning tool main-body part collides with an obstruction (for example, wall), since the cleaning tool main-body part is pulled by two points via two tension springs, Due to the frictional force and the restoring force of the tension spring, it is in contact with the obstacle and always moves while sliding over the obstacle. Thereby, the cleaning tool main-body part can clean the floor surface of the wall of an obstruction (for example, wall), always sliding the wall of an obstruction (for example, wall).

  In addition, of the two tension springs, the tension spring on the side where no obstacle is present is in a contracted state. Therefore, the tension spring is difficult to come into contact with the floor surface, and it is possible to prevent the linear member, that is, the tension spring, from being caught by some member or from being contaminated by dust on the floor surface.

  Moreover, the cleaning tool which concerns on 1 aspect of this invention is equipped with the pulley to which the restoring force is provided so that it may return to an original position when it rotates, The said linear member is the opposite side to the said connection part. It is good also as a structure by which the part is being fixed to the said pulley.

  According to said structure, when a cleaning tool main-body part collides with an obstruction (for example, wall), since it is pulled by two points via the linear member and the pulley which has restoring force, Due to the frictional force and the restoring force of the pulley, it touches the obstacle and always moves while sliding on the obstacle cage. Thereby, the cleaning tool main-body part can clean the floor surface of the wall of an obstruction (for example, wall), always sliding the wall of an obstruction (for example, wall).

  Further, when the cleaning tool main body is rotated, the linear member is drawn from the pulley on the side in contact with the obstacle, and conversely, the side not in contact with the obstacle is wound on the pulley. Therefore, the linear member is not easily loosened even when the cleaning tool main body rotates. Thereby, when a cleaning tool main-body part rotates, it is difficult to produce the situation where a linear member loosens and is caught in a certain member, or the linear member gets dirty.

  A cleaning device according to an aspect of the present invention is a travel device that pulls the cleaning tool by traveling by a driving source or by manual travel, to which any of the above cleaning tools and the linear member are connected. It is the structure equipped with.

  Thereby, when an obstacle (for example, wall) exists in the track of the cleaning tool main body, the cleaning tool main body can always clean the floor surface of the obstacle heel while sliding on the obstacle heel.
