Embodiments for Carrying Out the Invention

[0030] The present invention will now be described in more detail with reference to the drawings, with examples of embodiments and specific examples provided below, but the present invention is not limited to these embodiments and specific examples. Furthermore, it should be noted that the following diagrams used in the explanation are schematic, and the proportions of the dimensions may differ from those of reality. For ease of understanding, diagrams of components other than those necessary for the explanation have been omitted as appropriate.

[0031] (1) Configuration of the cleaning mechanism "First Embodiment" Figure 1 is a front view showing the opening and closing mechanism of a door equipped with the cleaning mechanism 1 according to this embodiment, Figure 2 is a perspective view showing the configuration of the cleaning mechanism 1 according to this embodiment, Figure 3(a) is a front view showing the contact between the cleaning body 3 of the cleaning mechanism 1 and the guide rail 140, (b) is a side view showing the contact between the door roller 120 and the guide rail 140, and (c) is an enlarged side view showing the contact between the guide rail 140 and the cleaning body 3. The overall configuration of cleaning mechanism 1 will be explained below with reference to the drawings.

[0032] (1.1) Door opening and closing mechanism with cleaning mechanism Figure 1 shows the opening and closing mechanism for the door 110 and the cleaning mechanism 1 for the guide rail 140, which are installed on the front side of the booth 100. As shown in Figure 1, the booth 100 is a box-shaped space with a desk (not shown), chair (not shown), lighting (not shown), etc. installed inside. Users can enter and exit the booth 100 by sliding open a door 110 that is installed on the front side of the booth 100.

[0033] The door 110 is movably suspended from a guide rail 140 via a holder 130 on which a door roller 120, which is an example of a contacting body, is rotatably supported. One of the retainers 130A is connected to the rod 151 of an actuator 150 that slides the door 110 along the guide rail 140. The other retainer 130B is connected to an automatic closing spring 160 that acts to pull the door 110 to the closed position.

[0034] The holder 130 is fitted with the cleaning mechanism 1 according to this embodiment. The cleaning mechanism 1 consists of a mounting body 2 that surrounds the top and sides of the door roller 120, and cleaning bodies 3 that are fixed to both ends of the mounting body 2 and contact the guide rail 140 from above. As shown in Figure 1, the cleaning bodies 3 are arranged to surround the door roller 120 on both sides in the direction of movement.

[0035] With the opening and closing mechanism of the door 110 equipped with the cleaning mechanism 1 configured in this way, when the actuator 150 operates and the door roller 120 is guided along the guide rail 140 and slides, the cleaning body 3 moves while in contact with the guide rail 140, removing dust accumulated on the guide rail 140 and preventing it from adhering to the door roller 120 that is guided along the guide rail 140.

[0036] (1.2) Configuration of cleaning mechanism 1 Figure 2 shows a perspective view of the cleaning mechanism 1 in a state where it is inserted at an angle into the convex curved surface 141 of the guide rail 140. The roller 120 is rotatably mounted on a support shaft 131 that is cantilevered on one side of the holder 130 (shown by a dashed line), and as shown in Figure 3(b), the concave curved surface 121 of the roller 120 fits into the convex curved surface 141 of the guide rail 140, making it difficult for the roller to derail from the guide rail 140.

[0037] Thus, because the concave curved surface 121 of the door roller 120 fits into the convex curved surface 141 of the guide rail 140 and moves, dust and other debris tend to accumulate on the convex curved surface 141 of the guide rail 140. As the door roller 120 rolls along, the accumulated dust is compressed, and there is a risk that the compressed clumps of dust will transfer to the concave curved surface 121 of the door roller 120.

[0038] Figure 11 shows a comparative example of a cleaning mechanism in which the cleaning body 30 protrudes vertically (perpendicular to) the direction of movement and is embedded in the circumferential surface of the convex curved surface 141 of the guide rail 140, with the casters 120 in between and facing each other. In this way, when the cleaning body 30, which is made of brushes, is embedded perpendicularly in the convex curved surface 141 of the guide rail 140, a gap W is generated between the brush and the circumferential surface of the convex curved surface 141 of the guide rail 140, as schematically shown in Figure 11(c), which may prevent the removal of dust and other debris accumulated on the convex curved surface 141 of the guide rail 140.

[0039] In the cleaning mechanism 1 of this embodiment, the cleaning body 3 moves together with the roller 120 while being inserted at an angle into the convex curved surface 141 of the guide rail 140. Specifically, the cleaning body 3 is composed of, for example, nylon brushes with a diameter of 0.3 mm to 0.8 mm, and as shown in Figure 3(a), it is positioned facing the roller 120, with the rollers facing each other, at an angle not perpendicular to the direction of movement and embedded in the circumferential surface of the convex curved surface 141 of the guide rail 140. As a result, as schematically shown in Figure 3(c), no gap is created between the brush and the circumferential surface of the convex curved surface 141 of the guide rail 140, and the brush comes into contact with the entire circumferential surface of the convex curved surface 141 of the guide rail 140, allowing the entire area where dust accumulates to be cleaned.

[0040] In this embodiment, the cleaning body 3 is held by a mounting body 2 that surrounds the upper part of the door roller 120, as shown in Figures 2 and 3(a). That is, the door roller 120, which moves while rolling on the guide rail 140, is surrounded on both sides by the cleaning body 3 in the direction of movement, and above, where it intersects with the direction of movement, it is surrounded by the mounting body 2. This prevents dust from rising and spreading in the area where the removed door roller 120 and the guide rail 140 come into contact.

[0041] Figure 4 schematically shows the fall of dust G that is cleaned and removed as the door roller 120 and the cleaning body 3 move along the guide rail 140. Note that in Figure 4, the dust G is shown greatly enlarged compared to reality for illustrative purposes. As shown in Figure 4(b), when the door 110 opens and the door roller 120 and cleaning body 3 move to the right end 140b of the guide rail 140, most of the dust G removed by the cleaning body 3 moves to the right end 140b of the guide rail 140. Also, the dust G that accumulates between the left cleaning mechanism 1A and the right cleaning mechanism 1B in Figure 4(a) moves along the guide rail 140 while being scraped off by the cleaning body 3 of the left cleaning mechanism 1A as the door roller 120 and cleaning body 3 move.

[0042] As shown in Figure 4(c), when the door 110 closes and the door roller 120 and cleaning body 3 move to the left end 140a of the guide rail 140, most of the dust G removed by the cleaning body 3 remains at the right end 140b of the guide rail 140 (see D1 in Figures 4(b) and (c)), and the dust G that accumulates between the left cleaning mechanism 1A and the right cleaning mechanism 1B is scraped off by the left cleaning mechanism 1A and remains at the moved position (see D2 in Figures 4(b) and (c)). In addition, the dust G at the left end 140a of the guide rail 140 will remain at that position regardless of the movement of the door 110. In this way, the dust G scraped off by the movement of the door roller 120 and the cleaning mechanism 1 as the door 110 opens and closes is more likely to fall to areas where its accumulation will not cause problems.

[0043] Figure 5 shows a configuration in which a collection container 4 for collecting dust removed by the cleaning mechanism 1 is located at the left end 140b of the guide rail 140. As shown in Figure 5, a dust transport member 5 for dust falling over the range of movement of the cleaning mechanism 1 may be provided below the guide rail 140, and a container 4 may be placed at the end of the transport direction. As the transport member 5, for example, a screw made of spiral blades or a spiral coil auger can be used. As shown by the arrows in Figure 5, when dust G scraped off by the cleaning body 3 of the cleaning mechanism 1 falls, it is transported by the transport member 5 to the left end 140a of the guide rail 140 and collected in the storage container 4.

[0044] Thus, according to the cleaning mechanism 1 of this embodiment, dust accumulating on the guide rail 140 is removed by the cleaning body 3 of the cleaning mechanism 1, which moves with the opening and closing of the door 110, and it is possible to prevent dust from adhering to the door roller 120, which acts as a contact body guided by the guide rail 140.

[0045] Furthermore, the cleaning body 3 may be positioned facing each other with the roller 120 in between, in a manner that it rubs against the circumferential surface of the convex curved surface 141 of the guide rail 140 without biting into it. Dust accumulated on the guide rail 140 is captured by the cleaning body 3 through electrostatic force as it moves in contact with it in a rubbing motion, thereby reducing the resistance of the cleaning body 3.

[0046] "Variation 1" Figure 6 is a front view showing the contact between the blade and the guide rail of the cleaning mechanism 1 according to modified example 1, and (b) is an enlarged side view showing the contact between the guide rail and the blade. The cleaning mechanism 1 according to Modification 1 is equipped with a blade 3A for scraping off attached material as a cleaning body. The blade 3A is made of urethane with a hardness of 60 to 80 degrees, and as shown in Figure 6(b), it is shaped to conform to the circumferential surface of the convex curved surface 141 of the guide rail 140, so that it can scrape off not only dust that accumulates on the convex curved surface 141 of the guide rail 140 as it moves, but also dust that is fixed to the convex curved surface 141.

[0047] "Variation 2" Figure 7 is a front view showing the contact between the foamed elastic body 3B and the guide rail 140 of the cleaning mechanism 1 according to modified example 2, and (b) is an enlarged side view showing the contact between the guide rail 140 and the foamed elastic body 3B. The cleaning mechanism 1 according to the modified example 2 includes a foamed elastic body 3B as a cleaning body for scraping off attached material. The foamed elastic body 3B is made of, for example, a urethane resin or silicone resin with an Asker C hardness of 30 to 50, and as shown in Figure 7(b), it is shaped so that its entire surface contacts the circumferential surface of the convex curved surface 141 of the guide rail 140. As it moves, it efficiently scrapes off dust that accumulates on the convex curved surface 141 of the guide rail 140, and a portion of the scraped-off dust can be retained within the foamed elastic body 3B.

[0048] "Variation 3" Figure 8 is a front view showing a nozzle 3C positioned non-contacting the guide rail 140 of the cleaning mechanism 1 according to modified example 3. The cleaning mechanism 1 according to Modification 3 includes a nozzle 3C that blows air onto the convex curved surface 141 of the guide rail 140 without contact, serving as the cleaning body. The nozzle 3C is connected to, for example, an air compressor (not shown) and is configured to discharge compressed air in conjunction with the opening and closing operation of the door 110, blowing away dust accumulated on the convex curved surface 141 of the guide rail 140. This eliminates resistance from the cleaning body.

[0049] "Second Embodiment" Figure 9 is a front view showing the door opening and closing mechanism equipped with the cleaning mechanism 1A according to this embodiment. The cleaning mechanism 1A includes a mounting body 2 that surrounds the top and sides of the door roller 120, and a cleaning body 3D that contacts the door roller 120 as a contact body that moves while straddling the guide rail 140 from above, and cleans the door roller 120. As shown in Figure 9, the cleaning body 3D is positioned to surround the door roller 120 on both sides in the direction of movement, and is configured to directly contact the concave curved surface 121 of the rolling door roller 120 to clean and remove dust adhering to the door roller 120.

[0050] The cleaning body 3D is composed of, for example, nylon brushes with a diameter of 0.1 mm to 0.5 mm, and contacts the door roller 120 in a manner that conforms to the concave curved surface 121 of the door roller 120 to remove dust adhering to the door roller 120. Furthermore, the cleaning unit 3D is held facing the roller 120, sandwiching it on both sides by the mounting unit 2 that covers the top of the roller 120. This prevents the dust removed from the roller 120 from rising and spreading.

[0051] "Variations" Figure 10 is a front view showing the arrangement of a modified cleaning mechanism 1A. The modified cleaning mechanism 1A is the left end 140 of the guide rail 140 in the direction of movement of the door roller 120. aIt is positioned to the side, and as the door 110 moves back and forth and returns to its original position to close the entrance to the booth 100, it comes into contact with the door roller 120 and cleans the concave curved surface 121 of the door roller 120.

[0052] According to the modified cleaning mechanism 1A, dust adhering to the concave curved surface 121 can always be cleaned and removed by contacting the roller 120 that starts moving and the roller 120 that moves back and forth and returns to its original position (see arrow R1 in the figure) at one end of the guide rail 140. The removed dust does not spread in the direction of movement of the guide rail 140 and is easy to collect at one end of the guide rail 140.

[0053] In the first and second embodiments, a configuration was described in which the door 110 is movably suspended from a guide rail 140 via a rotatably supported roller 120. However, if the door 110 is guided to reciprocate movement by a guide body at its lower end, a cleaning mechanism 1 may be installed to clean the guide body. Alternatively, if the door 110 is guided to reciprocate movement by the roller 120 and the guide rail at its lower end, cleaning mechanisms 1 and 1A may be installed to clean the guide rail or the roller.
