[0003] [Patent Document 1] JP 2010-143671 A Summary of the Invention [Problem to be solved by the invention]

[0004] When painting a wall, it is preferable to attach the protective material as close to the wall as possible in order to prevent paint from adhering to the floor. However, in the tool disclosed in Patent Document 1, the positional relationship between the frame, the rotating body, and the pressure roller makes it difficult to attach the protective material close to the wall.

[0005] An object of one aspect of the present invention is to provide a protective material application device that can apply protective material closer to a wall surface than conventional devices. [Means for solving the problem]

[0006] In order to solve the above problems, a protective material application device according to one embodiment of the present invention comprises a holding part that holds a roll of protective material so that it can rotate around the axis of the roll, and a pressure wheel that runs while pressing the protective material pulled out from the roll towards a floor surface, and on at least one of the left and right sides in the direction of travel of the pressure wheel, the side of the holding part and the side of the pressure wheel are configured to be flush with each other.

[0007] According to the above configuration, the holding part and the pressure wheel, whose side surfaces are flush with each other, are caused to run along the wall surface, so that the protective material can be applied closer to the wall surface than in the past.

[0008] In the curing material application tool according to one aspect of the present invention, the pressure wheel may be formed of an elastic body.

[0009] According to the above configuration, the influence of unevenness on the floor surface on the running of the pressing wheel is reduced.

[0010] In addition, a protective material application device according to one embodiment of the present invention further includes a guide wheel that rotates in contact with the protective material pulled out from the roll, guiding the protective material pulled out from the roll from the roll to the pressure wheel, and on the left and right sides of the traveling direction where the side of the holding part and the side of the pressure wheel are configured to be flush with each other, the side of the guide wheel may be configured to be flush with the side of the holding part and the side of the pressure wheel.

[0011] According to the above configuration, by running the pressure wheel so that the side of the guide wheel, which is configured to be flush with the side of the holding part and the side of the pressure wheel, run along the wall surface, the curing material can be easily attached to the floor surface close to the wall surface while being guided by the guide wheel.

[0012] In addition, the protective material application device according to one embodiment of the present invention further includes a frame that maintains a constant positional relationship between the holding portion and the pressure wheel, and the frame may have a hole into which a bar held by an operator can be inserted.

[0013] According to the above configuration, the worker can attach the curing material to the floor surface while holding the bar in a standing position, which reduces the time required for the work and reduces the physical burden on the worker.

[0014] In addition, in a protective material application device according to one aspect of the present invention, the protective material has an adhesive area that is adhesive to the floor surface on either the left or right side in the traveling direction, where the side of the holding part and the side of the pressing wheel are flush with each other, and the pressing wheel may run while pressing at least a part of the adhesive area toward the floor surface.

[0015] According to the above configuration, the pressure wheel is driven to press the adhesive area against the floor surface, thereby allowing the adhesive area to adhere to the floor surface.

[0016] In addition, in a protective material application device according to one aspect of the present invention, the holding part comprises a fixed member located at one end side in the axial direction of the roll, and a movable member located at the other end side in the axial direction of the roll and movable along the axial direction of the roll, and the one end side may be either the left or right side with respect to the traveling direction, where the side of the holding part and the side of the pressure wheel are configured to be flush with each other.

[0017] According to the above-mentioned configuration, the fixing member is disposed on the side where the side surface of the holding part and the side surface of the pressing wheel are configured to be flush with each other. Since the position of the fixing member is constant regardless of the axial length of the curing material roll, the side surface of the holding part and the side surface of the pressing wheel can be made flush with each other regardless of the length.

[0018] In addition, the protective material application tool according to one aspect of the present invention may further include a cutting guide that guides a cutting tool for cutting the protective material in a direction parallel to the axial direction of the roll.

[0019] According to the above configuration, the protective material applied to the floor surface can be easily cut from the roll of protective material by moving the cutting tool along the cutting guide. Effect of the Invention

[0020] According to one aspect of the present invention, it is possible to realize a protective material application device that can apply protective material closer to a wall surface than conventional devices. [Brief description of the drawings]

[0022] [Embodiment 1] Hereinafter, one embodiment of the present invention will be described in detail.

[0023] Fig. 1 is a perspective view showing the configuration of a protective material application tool 1 according to embodiment 1. Fig. 2 is a perspective view showing the protective material application tool 1 in a state in which a roll 100 of protective material wound in a cylindrical shape is attached. The protective material application tool 1 is a tool that pulls out protective material from the roll 100 and applies it to a floor surface or the like.

[0024] The protective material in this specification is a strip-shaped substrate having an adhesive region at one end in the width direction that is adhesive to a floor surface. The material of the substrate is not particularly limited, and may be, for example, patron paper or poly film. The adhesive region may be, for example, a region of an adhesive tape that is affixed to the substrate so that a portion of the tape in the width direction protrudes from the substrate. As shown in Figs. 1 and 2, the protective material application tool 1 includes a holding part 10 and a pressure wheel 20.

[0025] The holding unit 10 holds the curing material roll 100 so as to be rotatable around the axis of the roll 100. The holding unit 10 includes a first holding member 11 (fixed member) and a second holding member 12 (movable member). The first holding member 11 is located at one end side in the axial direction of the roll 100. The second holding member 12 is located at the other end side in the axial direction of the roll 100. In other words, the first holding member 11 and the second holding member 12 are located on opposite sides, that is, on the left and right sides in the running direction of the pressing wheel 20. For example, the first holding member 11 may be located on the left side in the running direction of the pressing wheel 20, and the second holding member 12 may be located on the right side in the running direction of the pressing wheel 20.

[0026] The first holding member 11 has a plate-shaped substrate 11a substantially parallel to an end face on one end side in the axial direction of the roll 100, and a contact member 11b provided on the surface of the substrate 11a facing the roll 100 and abutting against the roll 100. The second holding member 12 has a plate-shaped substrate 12a substantially parallel to an end face on the other end side in the axial direction of the roll 100, and a contact member 12b provided on the surface of the substrate 12a facing the roll 100 and abutting against the roll 100.

[0027] The holding unit 10 further includes a rail member 13 parallel to the axial direction of the roll 100. In Fig. 1, the holding unit 10 includes two rail members 13. However, the holding unit 10 may include one rail member 13 or three or more rail members 13.

[0028] The first holding member 11 is fixed to one end of a rail member 13. The second holding member 12 is movable along the rail member 13. The holding unit 10 further includes a biasing member (not shown) that biases the second holding member 12 in a direction along the rail member 13 toward the first holding member 11.

[0029] 3 is a diagram showing a state in which the second holding member 12 has been moved to the vicinity of the other end of the rail member 13. The second holding member 12 is provided with a knob 14 that enables an operator using the curing material application tool 1 to manually move the second holding member 12 toward the other end of the rail member 13. The operator holds the knob 14 and applies a force to the second holding member 12 in the opposite direction to the biasing force of the biasing member, thereby widening the gap between the first holding member 11 and the second holding member 12, as shown in FIG.

[0030] When the holding unit 10 holds the roll 100, the roll 100 is disposed between the first holding member 11 and the second holding member 12 with the distance between the first holding member 11 and the second holding member 12 widened. Then, the second holding member 12 is brought into contact with the roll 100, whereby the roll 100 is sandwiched between the first holding member 11 and the second holding member 12 by the biasing force of the biasing member.

[0031] The roll 100 has a cylindrical or columnar core material (not shown) along the axis. When the roll 100 is sandwiched between the first holding member 11 and the second holding member 12, the contact members 11b and 12b abut against the core material. The contact member 11b is rotatable around the axis of the roll 100 relative to the substrate 11a, and the contact member 12b is rotatable around the axis of the roll 100 relative to the substrate 12a. Therefore, when the roll 100 is sandwiched between the first holding member 11 and the second holding member 12, it is rotatable around the axis of the roll 100 together with the contact members 11b and 12b. However, the structure of the holding unit 10 is not limited to the above example as long as it can hold the roll 100 rotatably around the axis.

[0032] The holding unit 10 can hold the roll 100 of a length such that the position of the second holding member 12 is located at any position up to the other end of the rail member 13. For example, if the distance between the abutment members 11b, 12b is 500 mm when the second holding member 12 is located at the other end of the rail member 13, the holding unit 10 can hold the roll 100 of any length within the range of 500 mm or less in the axial direction.

[0033] The pressing wheel 20 travels while pressing the curing material pulled out from the roll 100 towards the floor surface. As the pressing wheel 20 travels, the curing material is attached to the floor surface, and at the same time, friction between the pressing wheel 20 and the curing material causes the curing material to be further pulled out from the roll 100. The width of the pressing wheel 20 is not particularly limited as long as it is possible to attach the curing material to the floor surface and further pull the curing material out from the roll 100, but may be within a range of, for example, 10 mm or more and 50 mm or less.

[0034] The pressing wheel 20 includes a first wheel 21 and a second wheel 22. The first wheel 21 and the second wheel 22 are located on opposite sides of the pressing wheel 20 in the traveling direction. For example, the first wheel 21 is located on the left side in the traveling direction, and the second wheel 22 is located on the right side in the traveling direction. The pressing wheel 20 may further include wheels other than the first wheel 21 and the second wheel 22.

[0035] The pressure wheel 20 is made of an elastic material. An example of the elastic material is sponge-like natural rubber. Another example of the elastic material may be urethane sponge, silicone rubber, or a laminate of two or more of these materials. As a result, even if there are irregularities on the floor surface, the pressure wheel 20 deforms, thereby reducing the effect of the irregularities on the running of the pressure wheel 20.

[0036] Such a pressing wheel 20 may wear out with the use of the curing material application tool 1. For this reason, the pressing wheel 20 has a structure that allows it to be replaced as necessary. For example, the pressing wheel 20 may be press-fitted into a wheel (not shown).

[0037] Fig. 4 is an enlarged front view of the vicinity of the first holding member 11 and the first wheel 21. In the curing material application tool 1, the side of the holding part 10 and the side of the pressing wheel 20 are flush with each other on at least one of the left and right sides relative to the traveling direction of the pressing wheel 20. In Fig. 4, the plane where the side of the holding part 10 and the side of the pressing wheel 20 are flush with each other is shown as plane F perpendicular to the paper. By running the pressing wheel 20 so that the holding part 10 and the pressing wheel 20, whose side surfaces are flush with each other, follow the wall surface, the worker can apply the curing material closer to the wall surface than before.

[0038] In particular, as shown in FIG. 4, on the left side in the running direction of the pressing wheel 20, the side of the first holding member 11 and the side of the first wheel 21 are configured to be flush with each other on the plane F. In other words, the side on which the first holding member 11 is arranged in the axial direction of the roll 100 is the side on which the side of the holding part 10 and the side of the pressing wheel 20 are configured to be flush with each other. As described above, the first holding member 11 is fixed to one end of the rail member 13. That is, the position of the first holding member 11 is constant regardless of the axial length of the roll 100. Therefore, by arranging the first holding member 11 on the side on which the side of the holding part 10 and the side of the pressing wheel 20 are configured to be flush with each other, the side of the holding part 10 and the side of the pressing wheel 20 can be made flush with each other regardless of the axial length of the roll 100.

[0039] For example, the worker may run the pressing wheel 20 in a state where the holding part 10 and the pressing wheel 20, which are configured with their side surfaces flush with each other, are in contact with the wall surface. In this case, the distance between the end of the curing material and the wall surface is approximately equal to the thickness of the substrate 11a of the first holding member 11 in the axial direction of the roll 100.

[0040] The protective material has an adhesive region that is adhesive to a floor surface at one end side in the axial direction of the roll 100. When using the protective material application device 1, the roll 100 is attached so that one end side is located on the side of the first holding member 11 and the first wheel 21. In other words, the roll 100 is attached so that the adhesive region is located on the side where the side surface of the holding part 10 and the side surface of the pressing wheel 20 are configured to be flush with each other.

[0041] The pressure wheel 20 runs while pressing at least a part of the adhesive area against the floor surface. In this way, by running the pressure wheel 20, the adhesive area can be pressed against the floor surface and adhered thereto.

[0042] In particular, the pressing wheel 20 whose side surface is configured to be flush with the side surface of the holding unit 10 runs while pressing the adhesive region toward the floor surface. For example, when the side surface of the first wheel 21 is flush with the side surface of the first holding member 11, the first wheel 21 may run while pressing the adhesive region toward the floor surface. In this case, by running the pressing wheel 20 with the sides of the holding unit 10 and the pressing wheel 20 that are flush with each other in contact with the wall surface, the adhesive region can be attached to the floor surface near the wall surface.

[0043] The curing material application tool 1 further includes a frame 30. The frame 30 maintains a constant positional relationship between the holding part 10 and the pressing wheel 20. There are no particular limitations on the material of the frame 30 as long as it has the rigidity to maintain the above-mentioned positional relationship.

[0044] The frame 30 has a hole 31 into which a bar 200 held by an operator can be inserted. As shown in Fig. 1, the bar 200 is attached to the curing material application tool 1 by inserting it into the hole 31. Specifically, a thread groove is formed on the end of the bar 200. The hole 31 is a screw hole into which the thread groove on the end of the bar 200 can be screwed.

[0045] The bar 200 may have a length that allows an upright worker to grasp the bar 200 when the protective material application tool 1 is positioned on the floor surface. When such a bar 200 is attached to the protective material application tool 1, the worker can grasp the bar 200 while standing to apply the protective material to the floor surface using the protective material application tool 1. Therefore, for example, the time required to apply the protective material to the floor surface is reduced, and the physical strain on the worker's knees, hips, etc. is reduced, compared to when the worker applies the protective material to the floor surface with his / her hands and knees on the floor surface.

[0046] In the curing material application tool 1, the first holding member 11 may be located on the right side in the traveling direction of the pressing wheel 20, and the second holding member 12 may be located on the left side in the traveling direction of the pressing wheel 20, as opposed to the above example. Also, the first wheel 21 may be located on the right side in the traveling direction of the pressing wheel 20, and the second wheel 22 may be located on the left side in the traveling direction of the pressing wheel 20. In this case, the side surface of the first holding member 11 and the side surface of the first wheel 21 are configured to be flush with each other on the right side in the traveling direction of the pressing wheel 20.

[0047] [Embodiment 2] Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals are given to members having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0048] Fig. 5 is a diagram showing a protective material application tool 2 according to embodiment 2. In Fig. 5, reference numeral 501 is a perspective view showing the configuration of the protective material application tool 2. Reference numeral 501 shows only the outline of the protective material 110 pulled out from the roll 100 held by the holding part 10. As shown by reference numeral 501, the protective material application tool 2 further includes a guide wheel 40 in addition to the respective components included in the protective material application tool 1.

[0049] The guide wheel 40 guides the curing material 110, which is pulled out from the roll 100, from the roll 100 to the pressing wheel 20. The guide wheel 40 contacts the region of the curing material 110 between the roll 100 and the pressing wheel 20. The guide wheel 40 rotates due to friction with the curing material 110.

[0050] The guide wheel 40 is subjected to pressure resulting from the tension of the protective material 110 between the roll 100 and the pressure wheel 20. There are no particular limitations on the material of the guide wheel 40 as long as it has enough rigidity to not deform under the pressure of the protective material 110 and generates a frictional force between the guide wheel 40 and the protective material 110 to rotate the guide wheel 40. The material of the guide wheel 40 may be, for example, polyacetal (POM) such as Duracon, or MC (monomer cast) nylon.

[0051] The guide wheels 40 include a first guide wheel 41 and a second guide wheel 42. In the axial direction of the roll 100 held by the holding unit 10, the position of the first guide wheel 41 is aligned with the position of the first wheel 21, and the position of the second guide wheel 42 is aligned with the position of the second wheel 22. The guide wheels 40 may further include guide wheels other than the first guide wheel 41 and the second guide wheel 42.

[0052] In FIG. 5, reference numeral 502 denotes an enlarged front view of the vicinity of the first holding member 11, the first wheel 21, and the first guide wheel 41. On the left and right sides of the traveling direction of the pressing wheel 20, where the side of the holding part 10 and the side of the pressing wheel 20 are flush with each other, the side of the guide wheel 40 is flush with the side of the holding part 10 and the side of the pressing wheel 20. For example, as shown in FIG. 5, on the left side in the traveling direction of the pressing wheel 20, the side of the first guide wheel 41 is flush with the side of the first holding member 11 and the side of the first wheel 21 in a plane F perpendicular to the paper surface of FIG. 5. This makes it possible to easily apply the protective material 110 to a floor surface close to a wall surface while guiding the protective material 110 by the guide wheel 40.

[0053] [Embodiment 3] Fig. 6 is a diagram showing a protective material application tool 3 according to a third embodiment. In Fig. 6, reference numeral 601 is a perspective view showing the configuration of the protective material application tool 3. Reference numeral 602 is a perspective view showing a method of cutting the protective material using the cutting tool 300. However, in Fig. 6, the roll 100 and the protective material 110 are omitted. As shown in Fig. 6, the protective material application tool 3 further includes a cutting guide 50 in addition to the respective components included in the protective material application tool 1.

[0054] The work of applying a protective material to a floor surface includes a process of cutting the protective material applied to the floor surface from the roll 100 by a cutting tool 300. An example of the cutting tool 300 is a utility knife.

[0055] The cutting guide 50 guides the cutting tool 300 in parallel to the axial direction of the roll 100. For example, the cutting guide 50 is located between the holder 10 and the pressing wheel 20, and has a guide surface 51 parallel to the axial direction of the roll 100. Specifically, the cutting guide 50 is attached to the rail member 13 of the curing material application tool 3 that is closest to the pressing wheel 20. There are no particular limitations on the material of the cutting guide 50 as long as it has the rigidity to guide the cutting tool 300. According to the curing material application tool 3, the curing material applied to the floor surface can be easily cut from the roll 100 by moving the cutting tool 300 along the guide surface 51 as shown by the reference numeral 602.

[0056] 6, as described above, the curing material application tool 3 further includes a cutting guide 50 in addition to the components included in the curing material application tool 1. However, the curing material application tool 3 may further include a cutting guide 50 in addition to the components included in the curing material application tool 2. In other words, the curing material application tool 3 may include both the cutting guide 50 and the guide wheel 40.

[0057] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention. [Explanation of symbols]
