Description

[Technical field]

[0001] The present invention relates to a screen stopper that regulates the opening and closing of a screen that constitutes a sliding window. [Background technology]

[0002] Conventionally, there are screen door stoppers that regulate the opening and closing of a screen door that constitutes a sliding window (see, for example, Patent Document 1). Screen door stoppers are effective when they come into contact with the shoji screen that constitutes the sliding window. Such screen door stoppers can restrict the entry and exit of children and pets such as cats, and can also prevent the screen door from moving due to strong winds, etc. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3207434 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the screen door stopper described in Patent Document 1 cannot adjust the left or right position of the stopper part, and depending on the combination of window and screen door, a gap may occur between the stopper and the shoji frame, reducing the insect-proofing effect.

[0005] On the other hand, a screen door stopper that is fixed with a screw has a position adjustment mechanism using the screw, so even if a gap occurs between the screen door and the stopper, the gap can be eliminated. However, the adjustment work of turning the screw is time-consuming.

[0006] The present invention has been made in consideration of the above problems, and has an object to provide a screen door stopper that can easily ensure the insect-proofing properties of a screen door. [Means for solving the problem]

[0007] In order to achieve the above object, the present invention provides a screen stopper (e.g., screen stopper 3 described later) that regulates the opening and closing of a screen (e.g., screen 140 described later) that constitutes a sliding window (e.g., sliding window 100 described later), the screen stopper comprising a base (e.g., base 10 described later) having an axis (e.g., axis described later) that protrudes in the direction in which the screen is opened and closed, an unlocking position (e.g., unlocking position P7 described later) that allows the screen to be opened and closed around the axis, and a mechanism that regulates the opening and closing of the screen by abutting against a frame of the sliding window. This screen door stopper rotates between a locked position (for example, locked position P8 described later) and a locked position (for example, locked position P9 described later), and slides in a direction along the axis (for example, directions X1 and X2 along the axis described later) at an adjustment position between the unlocked position and the locked position, allowing adjustment of the position in the direction along the axis, and is equipped with a stopper body (for example, stopper body 32 described later) that cannot slide in the direction along the axis in either the unlocked position or the locked position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the description of the second and subsequent embodiments, the same reference numerals will be used to denote configurations, actions, and effects common to other embodiments, and the description thereof will be omitted as appropriate.

[0010] First, a sliding window 100 to which the screen stoppers 1, 2, and 3 (see Figs. 2, 9, and 11, etc.) according to each embodiment of the present invention are attached will be described with reference to Fig. 1. Fig. 1 is a view of the sliding window 100 to which the screen stoppers 1, 2, and 3 (see Figs. 2, 9, and 11, etc.) are attached, viewed from the indoor side, and shows the front-to-back relationship of the inner screen 120, the outer screen 130, and the screen 140.

[0011] The sliding window 100 shown in Fig. 1 is constructed by housing an inner screen 120, an outer screen 130, and a screen door 140 in a frame 110 provided in an opening (reference number omitted) formed in a building. Specifically, the sliding window 100 includes the frame 110, the inner screen 120, the outer screen 130, the screen door 140, a crescent lock 150, a receiving bracket 151, and the like.

[0012] The frame 110 is attached to the periphery of an opening (reference number omitted) of a building so as to form a rectangular shape.

[0013] The inner screen 120 is housed within the frame 110 so as to be positioned in front of and to the right of the outer screen 130 as viewed from the indoor side. The inner screen 120 is rectangular and approximately half the size of the frame 110, and is opened and closed by sliding it left and right within the frame 110. Specifically, the inner screen 120 includes an upper rail 121 at the upper end, a middle rail 122 in the middle, a lower rail 123 at the lower end, a vertical frame 124 at the right end as viewed from the indoor side, a joining frame 125 at the left end as viewed from the indoor side, and glass sheets 126. Detailed explanations of each part of the inner screen 120 will be omitted.

[0014] The outer screen 130 is housed within the frame 110 so as to be positioned at the rear and left side of the inner screen 120 when viewed from the indoor side. The outer screen 130 is rectangular and approximately half the size of the frame 110, and is opened and closed by sliding it left and right within the frame 110. Specifically, the outer screen 130 includes an upper rail 131 at the upper end, a middle rail 132 in the middle, a lower rail 133 at the lower end, a vertical frame 134 at the left end when viewed from the indoor side, a joining frame 135 at the right end when viewed from the indoor side, and glass plates 136. Detailed explanations of each part of the outer screen 130 will be omitted.

[0015] The screen door 140 is housed within the frame 110 so as to be positioned at the rear of the outer screen 130 when viewed from the indoor side. This screen door 140 is rectangular and approximately half the size of the frame 110, and is opened and closed by sliding it left and right within the frame 110. Specifically, the screen door 140 includes an upper rail 141 at the upper end, a middle rail 142 in the middle, a lower rail 143 at the lower end, a vertical frame 144 at the left end when viewed from the indoor side, a vertical frame 145 at the right end when viewed from the indoor side, a screen 146, etc. A detailed explanation of each part of the screen door 140 will be omitted.

[0016] The crescent lock 150 is attached to the mating frame 125 of the inner screen 120, and locks the sliding window 100 by hooking a crescent (not shown) onto a receiving bracket 151 attached to the mating frame 135 of the outer screen 130.

[0017] [First embodiment] Next, the configuration of the screen door stopper 1 according to the first embodiment of the present invention will be described with reference to Figs. 2, 3A, 3B, 4, 5, and 6. Fig. 2 is a view of the sliding window 100 to which the screen door stopper 1 is attached, seen from the indoor side, showing the state in which the inner sash 120 is open and locked to restrict the opening and closing of the screen door 140. Fig. 3A is a perspective view of the screen door stopper 1 seen from the outdoor side, showing the state in which it is unlocked to allow the screen door 140 to be opened and closed. Fig. 3B is a perspective view of the screen door stopper 1 seen from the outdoor side, showing the state in which it is locked to restrict the opening and closing of the screen door 140. Fig. 4 is an exploded perspective view of the screen door stopper 1. Fig. 5 is an exploded top view of the screen door stopper 1. Fig. 6 is an exploded perspective view of the stopper body 12.

[0018] The screen door stopper 1 shown in Figures 2, 3A, 3B, 4, 5, and 6 is attached to the indoor side of the vertical frame 144 of the screen door 140, on the side of the vertical frame 145. When the inner screen 120 of the sliding window 100 is open and the screen door 140 is closed, this screen door stopper 1 restricts the opening and closing of the screen door 140 by locking the stopper body 12 by tilting it forward from the indoor side. Specifically, the screen door stopper 1 comprises a base 10, a fixing part 11, and a stopper body 12.

[0019] The base 10 is formed into an approximately C-shape when viewed from above, and is rotated in a direction that wraps around the rib 144a (see Figure 7A, etc.) of the vertical frame 144 of the screen door 140, and is hooked onto the vertical frame 144, so that it is positioned so as to come into contact with the vertical frame 144, and is fixed to the vertical frame 144 with a fixing part 11 and a screw S.

[0020] The base 10 has a pair of protrusions 13 on the surface facing the fixing part 11, which protrude in a direction perpendicular to the directions X1 and X2 in which the screen door 140 is opened and closed. The pair of protrusions 13 fit into a pair of holes 16 in the fixing part 11. The pair of protrusions 13 fit into the pair of holes 16, thereby strengthening the mutual engagement between the base 10 and the fixing part 11.

[0021] In addition, the base 10 has a shaft 14 that protrudes in the directions X1 and X2 in which the screen door 140 is opened and closed, and is inserted into a shaft hole 19 of the stopper body 12 to rotatably support the stopper body 12. The shaft 14 has a plurality of protrusions 15 on its circumferential surface that protrude toward the circumferential surface of the shaft hole 19 of the stopper body 12. The plurality of protrusions 15 fit into a plurality of recesses 20 that the shaft hole 19 of the stopper body 12 has on its circumferential surface. The plurality of protrusions 15 fit into any of the plurality of recesses 20 to position the rotating stopper body 12, and also allow the stopper body 12 to rotate by coming out of the plurality of recesses 20.

[0022] Fixing part 11 has groove 11a into which rib 144a (see FIG. 7A) of vertical frame 144 of screen door 140 fits. Fixing part 11 is fixed to base 10 with screw S with rib 144a (see FIG. 7A) fitted into groove 11a, thereby preventing base 10 from rotating in the direction opposite to the direction in which rib 144a (see FIG. 7A) is wound up, maintaining base 10 hooked onto vertical frame 144 of screen door 140. As a result, base 10 is fixed to vertical frame 144 of screen door 140.

[0023] Furthermore, the fixing part 11 has, on its surface facing the base 10, a pair of holes 16 into which the pair of protrusions 13 of the base 10 fits. The pair of protrusions 13 of the base 10 fits into the pair of holes 16. The pair of protrusions 13 fit into the pair of holes 16, thereby strengthening the mutual engagement between the base 10 and the fixing part 11.

[0024] Specifically, the fixing part 11 has a pair of upper and lower holding parts 17 and a connecting part 18. The pair of upper and lower holding parts 17 are each formed into a substantially L-shape in a cross section when cut in the horizontal direction, and are parts that hold the base 10. The pair of upper and lower holding parts 17 are elastically deformed in a direction in which the angle of the substantially L-shape widens when fixed to the base 10. For example, the pair of upper and lower holding parts 17 are formed into a substantially L-shape of 85 degrees, and are elastically deformed into a substantially L-shape of 90 degrees when fixed to the base 10. The connecting part 18 connects the pair of upper and lower holding parts 17 to each other. The connecting part 18 is formed integrally with the pair of upper and lower holding parts 17.

[0025] The stopper body 12 is provided on the shaft 14 of the base 10, and rotates between a first position P1 (see Figs. 3A and 8A) that allows the screen door 140 to be opened and closed, a second position P2 (see Figs. 3B and 8C) that restricts the opening and closing of the screen door 140 by hitting the outer screen 130 of the sliding window 100, and a third position P3 (see Fig. 8D) that allows the screen door 140 to be opened and closed, and is positioned at each of these positions. Note that the second position P2 (see Figs. 3B and 8C) is preferably a position rotated approximately 90 degrees from the first position P1 (see Figs. 3A and 8A), and the third position P3 (see Fig. 8D) is preferably a position rotated approximately 90 degrees from the second position P2 (see Figs. 3B and 8C).

[0026] This stopper body 12 has a shaft hole 19 into which the shaft 14 of the base 10 is inserted. The shaft hole 19 has a plurality of recesses 20 on the circumferential surface thereof into which the protrusions 15 of the shaft 14 fit. The plurality of recesses 20 fit into the plurality of protrusions 15 that the shaft 14 of the base 10 has on its circumferential surface. The plurality of recesses 20 position the rotating stopper body 12 by fitting the plurality of protrusions 15 into them, and allow the stopper body 12 to rotate by removing the plurality of protrusions 15 from them.

[0027] The stopper body 12 also has a pair of small parts 21, 22 that sandwich the shaft 14. One small part 21 has claws 21a, 21b in the directions X1, X2 along the shaft. The claw 21a is arranged in a direction substantially perpendicular to the shaft 14, and is hooked onto the other small part 22. The claw 21b is arranged in the directions X1, X2 in which the screen door 140 is opened and closed, and is hooked onto the other small part 22. This claw 21b is elastically deformed in the direction substantially perpendicular to the shaft 14, so that it can be removed from the other small part 22.

[0028] The pair of small parts 21, 22 are originally divided into two parts by a surface that is approximately parallel to the shaft hole 19 and extends from the base end side (the front right side in FIG. 6) having the shaft hole 19 to the tip end side (the rear left side in FIG. 6), and are joined together to form the shaft hole 19. The pair of small parts 21, 22 are connected to each other at least at the tip end side (the rear left side in FIG. 6) by claws 21a, 21b. In addition, the peripheral surface of the shaft hole 19 of the pair of small parts 21, 22 is pressed by the protrusion 15 of the shaft 14, and at least the base end side (the front right side in FIG. 6) is moved in a direction away from each other by elastic deformation, so that the shaft hole 19 is enlarged in diameter. Furthermore, the pair of small parts 21, 22 are moved in a direction approaching each other with the protrusion 15 of the shaft 14 fitting into the recess 20 of the shaft hole 19, so that the shaft hole 19 returns to its original diameter. In this manner, the stopper body 12 is elastically deformed and the shaft hole 19 is enlarged in diameter, so that the projection 15 of the shaft 14 can escape from the recess 20 of the shaft hole 19 .

[0029] Next, the procedure for attaching the screen door stopper 1 to the sliding window 100 will be described with reference to Figures 7A, 7B, 7C, and 7D. Figure 7A is a top view explaining the procedure for attaching the screen door stopper 1 to the sliding window 100, showing the state immediately before the base 10 is attached. Figure 7B is a top view explaining the procedure for attaching the screen door stopper 1 to the sliding window 100, showing the state in which it is hooked on the rib 144a of the vertical frame 144 of the screen door 140. Figure 7C is a top view explaining the procedure for attaching the screen door stopper 1 to the sliding window 100, showing the state immediately before the fixing part 11 is attached. Figure 7D is a top view explaining the procedure for attaching the screen door stopper 1 to the sliding window 100, showing the state immediately before fixing with the screw S.

[0030] First, base 10, which is formed in a roughly C-shape when viewed from above, is positioned so that the open side of the C faces the tip of rib 144a of vertical frame 144 of screen door 140 (see FIG. 7A).

[0031] Thereafter, the base 10 is abutted against the vertical frame 144 so that the rib 144a fits into the open part of the C-shape, and then the rib 144a is rotated 90 degrees in the rolling direction (counterclockwise when viewed from above) to hook it onto the vertical frame 144 (see FIG. 7B).

[0032] Thereafter, fixing part 11, which is formed in a substantially L-shape when viewed from above, is arranged so that groove 11a formed on the inside faces the tip of rib 144a of vertical frame 144 (see FIG. 7C).

[0033] Thereafter, the fixing part 11 is brought into contact with the vertical frame 144 so that the rib 144a fits into the groove 11a, and then fixed to the base 10 with the screw S (see FIG. 7D). As a result, the base 10 is fixed to the vertical frame 144 of the screen door 140.

[0034] Next, the movement of the screen door stopper 1 will be described with reference to Figures 8A, 8B, 8C, and 8D. Figure 8A is a front view of the screen door stopper 1, showing the stopper body 12 positioned at the first position P1. Figure 8B is a front view of the screen door stopper 1, showing the stopper body 12 positioned between the first position P1 and the second position P2. Figure 8C is a front view of the screen door stopper 1, showing the stopper body 12 positioned at the second position P2. Figure 8D is a front view of the screen door stopper 1, showing the stopper body 12 positioned at the third position P3.

[0035] 8A, when stopper body 12 is in first position P1 that allows screen door 140 to be opened and closed, at least one of multiple protrusions 15 provided on the circumferential surface of shaft 14 fits into one of multiple recesses 20 provided on the circumferential surface of shaft hole 19. This positions stopper body 12 in first position P1.

[0036] As shown in Figure 8B, when stopper body 12 is rotated from first position P1 (see Figure 8A), which allows screen door 140 to be opened and closed, to second position P2 (see Figure 8C), which restricts opening and closing of screen door 140, protrusion 15 of shaft 14, which is fitted into one of multiple recesses 20 provided on the circumferential surface of shaft hole 19, escapes from recess 20 while pressing against the circumferential surface of shaft hole 19. This causes stopper body 12 to elastically deform, and shaft hole 19 to expand in diameter.

[0037] 8C, when stopper body 12 is located at second position P2 that restricts the opening and closing of screen door 140, at least one of multiple protrusions 15 provided on the circumferential surface of shaft 14 fits into one of multiple recesses 20 provided on the circumferential surface of shaft hole 19. As a result, stopper body 12 is positioned at second position P2.

[0038] 8D, when stopper body 12 is in third position P3 that allows screen door 140 to be opened and closed, at least one of multiple protrusions 15 provided on the circumferential surface of shaft 14 fits into one of multiple recesses 20 provided on the circumferential surface of shaft hole 19. This positions stopper body 12 in third position P3.

[0039] Note that, here, Figure 8B has been used to explain an example of rotating the stopper body 12 from the first position P1 (see Figure 8A) to the second position P2 (see Figure 8C); however, the same behavior is observed when rotating the stopper body 12 from one position to another, such as when rotating the stopper body 12 from the second position P2 (see Figure 8C) to the third position P3 (see Figure 8D), and therefore detailed explanations are omitted.

[0040] The above-mentioned screen door stopper 1 is a screen door stopper 1 that regulates the opening and closing of a screen door 140 that constitutes a sliding window 100, and comprises a base 10 that is arranged so as to come into contact with a vertical frame 144 of the screen door 140, a fixing part 11 that is fixed to the base 10 and thereby fixes the base 10 to the vertical frame 144, and a stopper body 12 that is provided on the base 10 and moves between a first position P1 that allows the screen door 140 to be opened and closed, and a second position P2 that regulates the opening and closing of the screen door 140 by coming into contact with the outer shoji 130 of the sliding window 100.

[0041] In addition, the base 10 is moved in a predetermined direction and hooked onto the vertical frame 144, and is positioned so as to come into contact with the vertical frame 144, and the fixing part 11 maintains the base 10 hooked onto the vertical frame 144, thereby fixing the base 10 to the vertical frame 144.

[0042] In addition, the base 10 is hooked onto the vertical frame 144 by rotating the rib 144a of the vertical frame 144, which is formed in an approximately L-shape in cross section when cut horizontally, in the rolling-up direction, and the fixing part 11 prevents the base 10 from rotating in the direction opposite to the rolling-up direction, thereby maintaining the base 10 hooked onto the vertical frame 144.

[0043] In addition, the fixing part 11 is formed in an approximately L-shape when viewed in cross section when cut horizontally, and has a pressing portion 17 that presses the base 10, and when the pressing portion 17 is fixed to the base 10, it elastically deforms in a direction widening the angle of the approximately L-shape.

[0044] In addition, base 10 has projection 13 that protrudes in a direction perpendicular to directions X1, X2 in which screen door 140 is opened and closed, and fixing part 11 has hole 16 into which projection 13 fits.

[0045] In addition, the base 10 has an axis 14 protruding in the directions X1 and X2 in which the screen door 140 is opened and closed, and the stopper body 12 rotates around the axis 14 between a first position P1 and a second position P2.

[0046] In addition, the stopper body 12 has a pair of small parts 21, 22 that sandwich the shaft 14, and one small part 21 has a claw 21b that is hooked onto the other small part 22 and can be detached from the other small part 22 by being elastically deformed in a direction approximately perpendicular to the shaft 14.

[0047] In this way, the screen door stopper 1 can be attached to the vertical frame 144 of the screen door 140 without using adhesive tape or drilling screw holes, so it can be easily attached and detached. Also, since it is fixed to the vertical frame 144, the height at which it is fixed can be freely determined. For example, it can be fixed at a height that is out of reach of children. Furthermore, since the protrusion 13 of the base 10 is fitted into the hole 16 of the fixing part 11, and one small part 21 has a claw 21b that is hooked onto the other small part 22 and is elastically deformed in a direction approximately perpendicular to the axis 14 to be removed from the other small part 22, the risk of breakage or falling off can be reduced. This improves durability and allows it to be installed in places where the influence of wind is strong, such as on high floors.

[0048] The screen door stopper 1 regulates the opening and closing of a screen door 140 that constitutes a sliding window 100, and comprises a base 10 fixed to a vertical frame 144 of the screen door 140, and a stopper body 12 that is provided on the base 10 and moves between a first position P1 that allows the screen door 140 to be opened and closed, a second position P2 that abuts against the outer shoji screen 130 of the sliding window 100 to regulate the opening and closing of the screen door 140, and a third position P3 that allows the screen door 140 to be opened and closed, and is positioned at each of the first position P1, the second position P2, and the third position P3.

[0049] In addition, the base 10 has an axis 14 protruding in the directions X1 and X2 in which the screen door 140 is opened and closed, and the stopper body 12 has an axis hole 19 into which the axis 14 is inserted, and the stopper body 12 rotates around the axis 14 between a first position P1, a second position P2, and a third position P3.

[0050] In addition, the shaft 14 has a protrusion 15 on the circumferential surface of the shaft 14 that protrudes toward the circumferential surface of the shaft hole 19, and the shaft hole 19 has a plurality of recesses 20 on the circumferential surface of the shaft hole 19 into which the protrusion 15 fits, and the stopper body 12 is positioned at any of a first position P1, a second position P2, or a third position P3 when the protrusion 15 is fitted into any of the plurality of recesses 20.

[0051] Furthermore, the stopper body 12 is elastically deformed to expand the diameter of the shaft hole 19, thereby allowing the protrusion 15 to escape from the recess 20.

[0052] In addition, the stopper body 12 has an axial hole 19 portion which is divided into two by a surface that is approximately parallel to the axial hole 19 and runs from the base end side having the axial hole 19 to the tip end side, and has a pair of small parts 21, 22 that are connected to each other at least on the tip side, and the pair of small parts 21, 22 are moved in a direction away from each other at least on the base end side, thereby expanding the diameter of the axial hole 19.

[0053] In this way, the screen door stopper 1 can be used in a variety of situations. Specifically, it is equipped with a stopper body 12 that is positioned at each of a first position P1 that allows the screen door 140 to be opened and closed, a second position P2 that restricts the opening and closing of the screen door 140 by hitting the outer screen 130, and a third position P3 that allows the screen door 140 to be opened and closed, so that although it is a single product, it can be used in the same way as each of the products that are symmetrical (opposite sides).

[0054] [Second embodiment] Next, the configuration of the screen door stopper 2 according to the second embodiment of the present invention will be described with reference to Figures 9, 10A, and 10B. Figure 9 is a view of a sliding window 100 to which the screen door stopper 2 is attached, viewed from the indoor side, showing a state in which the outer screen 130 is open and locked to restrict the opening and closing of the screen door 140. Figure 10A is a perspective view of the screen door stopper 2 viewed from the outdoor side, showing a state in which it is unlocked to allow the screen door 140 to be opened and closed. Figure 10B is a perspective view of the screen door stopper 2 viewed from the outdoor side, showing a state in which it is locked to allow the screen door 140 to be opened and closed.

[0055] The screen door stopper 2 shown in Figures 9, 10A and 10B differs from the screen door stopper 1 of the first embodiment (see Figure 2, etc.) in that it is equipped with a spacer 31 and related points.

[0056] The screen door stopper 2 is attached to the indoor side of the vertical frame 145 of the screen door 140, on the side of the vertical frame 144. When the outer screen 130 of the sliding window 100 is open and the screen door 140 is closed, this screen door stopper 2 restricts the opening and closing of the screen door 140 by locking the stopper body 12 by tilting it forward from the indoor side. Specifically, the screen door stopper 2 has the same basic configuration as the screen door stopper 1 according to the first embodiment (see FIG. 2, etc.), and additionally includes a spacer 31.

[0057] The spacer 31 is provided between the base 10 and the fixing parts 11 and the stopper body 12, and maintains a distance between the base 10 and the fixing parts 11 in the stopper body 12. Like the stopper body 12, the spacer 31 rotates between a fourth position P4 that allows the screen door 140 to be opened and closed, a fifth position (not shown) that restricts the opening and closing of the screen door 140 by hitting the outer screen 130, and a sixth position (not shown) that allows the screen door 140 to be opened and closed, and is positioned at each position. Note that the fifth position P5 is a position rotated approximately 90 degrees from the fourth position P4, and the sixth position (not shown) is preferably a position rotated approximately 90 degrees from the fifth position (not shown).

[0058] The above-mentioned screen door stopper 2 is provided with spacers 31 which are provided between the base 10 and each of the fixing parts 11 and the stopper body 12, and which maintain the distance between the base 10 and each of the fixing parts 11 on the stopper body 12.

[0059] In addition, the spacer 31 moves between a fourth position P4 that allows the screen door 140 to be opened and closed, and a fifth position (not shown) that restricts the opening and closing of the screen door 140 by contacting the outer screen 130.

[0060] In this way, according to the screen door stopper 2, the spacer 31, which maintains the distance between the base 10 and the fixing part 11 in the stopper body 12, moves between a fourth position P4 that allows the screen door 140 to be opened and closed, and a fifth position (not shown) that restricts the opening and closing of the screen door 140 by hitting the outer screen 130, just like the stopper body 12, so that either the stopper body 12 or the spacer 31 can be used as a stopper depending on the distance between the vertical frames 144, 145 of the screen door 140 and the vertical frame 134 or the meeting frame 135 of the outer screen 130. This allows it to be used as the screen door stopper 2 when the outer screen 130 is open, and also as the screen door stopper 2 when the inner screen 120 is open.

[0061] [Third embodiment] Next, the configuration of the screen door stopper 3 according to the third embodiment of the present invention will be described with reference to Figs. 11, 12A, 12B, and 13. Fig. 11 is a view of a sliding window 100 to which the screen door stopper 3 is attached, viewed from the indoor side, showing a state in which the inner screen 120 is open and locked to restrict the opening and closing of the screen door 140. Fig. 12A is a perspective view of the screen door stopper 3 viewed from the outdoor side, showing a state in which it is unlocked to allow the screen door 140 to be opened and closed. Fig. 12B is a perspective view of the screen door stopper 3 viewed from the outdoor side, showing a state in which it is locked to restrict the opening and closing of the screen door 140. Fig. 13 is an exploded perspective view of the screen door stopper 3.

[0062] The screen door stopper 3 shown in Figures 11, 12A, 12B and 13 differs from the screen door stopper 1 of the first embodiment (see Figure 2, etc.) in that it has a stopper body 32 instead of the stopper body 12, and in other associated points.

[0063] The screen door stopper 3 is attached to the indoor side of the vertical frame 144 of the screen door 140, on the side of the vertical frame 145. When the outer screen 130 of the sliding window 100 is open and the screen door 140 is closed, this screen door stopper 3 restricts the opening and closing of the screen door 140 by locking the stopper body 32 by tilting it forward from the indoor side. Specifically, the screen door stopper 3 has a similar basic configuration to the screen door stopper 1 according to the first embodiment (see FIG. 2, etc.), and includes the stopper body 32 instead of the stopper body 12 (see FIG. 2, etc.).

[0064] Base 10 has, in place of shaft 14 (see FIG. 4, etc.), shaft 23 that protrudes in directions X1, X2 in which screen door 140 is opened and closed, and that rotatably supports stopper body 32 by being inserted into shaft hole 25 of stopper body 32. Shaft 23 has grooves 24 on its circumferential surface into which protrusions 26 that shaft hole 25 of stopper body 32 has on its circumferential surface fit.

[0065] The groove 24 is a path into which the projection 26, which the shaft hole 25 of the stopper body 32 has on its circumferential surface, fits and along which the projection 26 slides. Specifically, the groove 24 has a first groove 24a and a plurality of second grooves 24b. The first groove 24a extends in the directions X1 and X2 along the shaft 23, and allows the stopper body 32 in the adjustment position P9 (see Figs. 14C and 15C) to slide in the directions X1 and X2 along the shaft 23. The second grooves 24b extend so as to intersect the first groove 24a at a substantially right angle and to be spaced apart from each other in the direction along the first groove 24a, and allow the stopper body 32 to rotate between the unlocked position P7 (see Figs. 14A and 15A) and the locked position P8 (see Figs. 14B and 15B). Each of the second grooves 24b has a shape in which the portions intersecting with the first grooves 24a become wider toward the first grooves 24a.

[0066] The stopper body 32 has an axis hole 25 into which the axis 23 of the base 10 is inserted, and rotates around the axis 23 between an unlocked position (first position) P7 (see Figures 14A and 15A), which allows the screen door 140 to be opened and closed, and a locked position (second position) P8 (see Figures 14B and 15B), which restricts the opening and closing of the screen door 140 by contacting the outer screen 130 of the sliding window 100. The stopper body 32 can be adjusted in the direction along the axis 23 by sliding in the directions X1 and X2 along the axis 23 at an adjustment position P9 (see Figs. 14C and 15C) between the unlocked position P7 (see Figs. 14A and 15A) and the locked position P8 (see Figs. 14B and 15B), and cannot be slid in the directions X1 and X2 along the axis 23 at each of the unlocked position P7 (see Figs. 14A and 15A) and the locked position P8 (see Figs. 14B and 15B). The locked position P8 (see Figs. 14B and 15B) is a position rotated approximately 90 degrees from the unlocked position P7 (see Figs. 14A and 15A), and the adjusted position P9 (see Figs. 14C and 15C) is preferably an intermediate position between the respective positions.

[0067] The shaft hole 25 has a protrusion 26 on the circumferential surface of the shaft 23 of the base 10. The protrusion 26 fits into a groove 24 on the circumferential surface of the shaft 23 of the base 10 and slides in the groove 24. The protrusion 26 has a shape in which the portions facing both ends of the second groove 24b are tapered. For example, the protrusion 26 is rhombic.

[0068] Next, the movement of the screen door stopper 3 will be described with reference to Figures 14A, 14B, 14C, 15A, 15B, and 15C. Figure 14A is an external perspective view of the screen door stopper 3, showing the state in which the stopper body 32 is positioned at the unlocked position P7. Figure 14B is an external perspective view of the screen door stopper 3, showing the state in which the stopper body 32 is positioned at the locked position P8. Figure 14C is an external perspective view of the screen door stopper 3, showing the state in which the stopper body 32 is positioned at the adjusted position P9. Figure 15A is a schematic diagram of the screen door stopper viewed from the shaft hole side, showing the state in which the stopper body 32 is positioned at the unlocked position P7. Figure 15B is a schematic diagram of the screen door stopper viewed from the shaft hole side, showing the state in which the stopper body 32 is positioned at the locked position P8. FIG. 15C is a schematic diagram of the screen door stopper viewed from the shaft hole side, showing the state in which the stopper body 32 is located at the adjustment position P9.

[0069] 14A and 15A, when the stopper body 32 is located at the unlocked position P7 that allows the screen door 140 to be opened or closed, the protrusion 26 of the shaft hole 25 of the stopper body 32 fits into the second groove 24b, and the stopper body 32 is positioned at the unlocked position P7. At this time, the stopper body 32 cannot slide in the directions X1 and X2 along the shaft 23.

[0070] 14B and 15B, when the stopper body 32 is located at the locked position P8 that restricts the opening and closing of the screen door 140, the protrusion 26 of the shaft hole 25 of the stopper body 32 fits into the second groove 24b, and the stopper body 32 is positioned at the locked position P8. At this time, the stopper body 32 cannot slide in the directions X1 and X2 along the shaft 23.

[0071] 14C and 15C, when the stopper body 12 is located at the adjustment position P9, the protrusion 26 of the shaft hole 25 of the stopper body 32 is fitted into the first groove 24a and is slidable in the directions X1 and X2 along the axis 23. In other words, the stopper body 32 is slidable in the directions X1 and X2 along the axis 23, and the position of the stopper body 32 in the directions X1 and X2 along the axis 23 is adjustable.

[0072] The above-mentioned screen door stopper 3 is a screen door stopper 3 that regulates the opening and closing of the screen door 140 that constitutes the sliding window 100, and is fixed to the vertical frame 144 of the screen door 140, and is equipped with a base 10 having an axis 23 that protrudes in the directions X1, X2 in which the screen door 140 is opened and closed, and a stopper body 32 that rotates around the axis 23 between an unlocked position P7 that allows the screen door 140 to be opened and closed, and a locked position P8 that regulates the opening and closing of the screen door 140 by abutting against the outer screen 130 of the sliding window 100, and that slides in the directions X1, X2 along the axis 23 at an adjustment position P9 between the unlocked position P7 and the locked position P8, allowing position adjustment in the directions X1, X2 along the axis 23, and that is unable to slide in the directions X1, X2 along the axis 23 in either the unlocked position P7 or the locked position P8.

[0073] In addition, the shaft hole 25 has a protrusion 26 on its circumferential surface that protrudes toward the circumferential surface of the shaft 23, and the shaft 23 has a groove 24 on its circumferential surface into which the protrusion 26 fits. The groove 24 has a first groove 24a extending in the directions X1 and X2 along the shaft 23 and enabling the stopper body 32 at the adjustment position P9 to slide in the directions X1 and X2 along the shaft 23, and a plurality of second grooves 24b extending so as to intersect the first groove 24a at approximately a right angle and to be spaced apart from each other in the direction along the first groove 24a, enabling the stopper body 32 to rotate between the unlocked position P7 and the locked position P8.

[0074] Moreover, the projection 26 has a shape in which the portions facing both ends of the second groove 24b are tapered.

[0075] Further, the second groove 24b has a shape in which the portion intersecting with the first groove 24a becomes wider toward the first groove 24a.

[0076] In this way, with the screen door stopper 3, the position of the stopper body 32 can be adjusted by sliding the stopper body 32 at the adjustment position P9 in the directions X1 and X2 in which the screen door 140 is opened and closed. This eliminates any gaps that may occur between the screen door stopper 3 and the outer door 130, preventing the screen door 140 from moving. As a result, the insect-proofing properties of the screen door 140 can be easily ensured. In addition, the protrusion 26, which is provided around the shaft hole 25 of the stopper body 32 and convex toward the periphery of the shaft 23 of the base 10, has a tapered shape.Furthermore, among the grooves 24, which are provided around the shaft 23 of the base 10 and into which the protrusion 26 fits, the portion of the multiple second grooves 24b that intersect with the first groove 24a at approximately right angles has a shape that widens toward the first groove 24a.As a result, the protrusion 26 can easily enter the second groove 24b from the first groove 24a, and the stopper body 32 can be easily rotated.

[0077] According to the screen door stopper of the present invention, the position of the stopper body can be adjusted by sliding the stopper body in the adjustment position in the direction in which the screen door is opened or closed. This can eliminate the gap between the screen door stopper and the shoji screen, and prevent the screen door from moving. As a result, the insect-proofing of the screen door can be easily ensured. In addition, the protrusion that is provided around one of the axis of the base and the axis hole of the stopper body and that is convex toward the other periphery has a tapered shape, and further, among the grooves that are provided around the other of the axis of the base and the axis hole of the stopper body and into which the protrusion fits, the part that intersects with the first groove in the multiple second grooves that intersect with the first groove at approximately a right angle has a shape that becomes wider toward the first groove, so that the protrusion can easily enter the second groove from the first groove, and the stopper body can be easily rotated.
