Embodiments for Carrying Out the Invention
[0009] Hereinafter, preferred embodiments of the fitting according to the present invention will be described in detail with reference to the accompanying drawings. In the following, for convenience, the terms "prospective direction" and "search direction" may be used. The prospective direction is the direction along the depth of the fitting as indicated by arrow A in the figure. A surface along the prospective direction may be referred to as a prospective surface. The search direction is the direction along the up and down perpendicular to the prospective direction in the case of an object extending along the horizontal direction such as the upper frame. In the case of an object extending along the vertical direction such as a vertical frame, the direction along the horizontal perpendicular to the prospective direction is referred to as the search direction. A surface along the search direction may be referred to as a search surface.
[0010] Figures 1 and 2 show a fitting according to an embodiment of the present invention. The fitting exemplified here is called a single-opening door and includes a frame body 10 and a door body (face material) 20. The frame body 10 is configured by providing an upper frame 12 between the upper end portions of the left and right vertical frames 11. The door body 20 is configured by attaching an upper frame 22, a lower frame 23, and left and right vertical frames 24 to the four circumferences of a panel 21 such as a glass plate having a rectangular shape. This door body 20 is supported by the frame body 10 by a hinge 1 provided between one vertical frame 24 of the door body 20 and one vertical frame 11 of the frame body 10, and can open and close the opening of the frame body 10 by rotating around a hinge axis along the up and down direction. Handles 25 are attached to both sides of the portion of the panel 21 that becomes the door tip. The vertical frames 11, the upper frame 12 that constitute the frame body 10, and the upper frame 22, the lower frame 23, and the vertical frames 24 that constitute the door body 20 are extruded profiles formed of a metal such as an aluminum alloy, and are configured such that the portions along the entire length in the longitudinal direction each have a substantially uniform cross-sectional shape. Hereinafter, the configuration of the vertical frame 11 of the frame body 10 and the vertical frame 24 of the door body 20 will be described in detail, and the characteristic portions of the present application will be described together. In the following, for convenience, it will be described assuming that the above-described fitting is provided at a position partitioning between room a and room b, and is configured to protrude toward the b room side when the door body 20 is opened.
[0011] The vertical frame 11 of the frame body 10 has a symmetric shape with respect to the left and right, and the frame main body portion 11a and the finding wall portion 11b are integrally formed. The frame main body portion 11a has a hollow cylindrical shape with a substantially rectangular cross-section. The finding wall portion 11b protrudes inward along the finding direction from the corner on the a room side on the inner peripheral side of the frame body 10. The protruding dimension of this finding wall portion 11b is set so that the inner peripheral edge faces the finding surface facing the a room of the vertical frame 24 when the door body 20 is closed. A seal member 11c for ensuring airtightness between the door body 20 is attached over substantially the entire length of the vertical frame 11 to the portion facing the b room at the protruding edge portion of the finding wall portion 11b. The seal member 11c has a contact piece portion 11c1 forming a single tongue shape, and can contact the door body 20 without a gap by appropriately elastically deforming the contact piece portion 11c1 when the door body 20 is closed.
[0012] On the frame body portion 11a of the vertical frame 11, a plurality of suction members 2 are provided at a plurality of locations along the longitudinal direction on the prospective surface on the inner peripheral side. The suction member 2 has a mounting plate portion 2a and a suction plate portion 2b, and is integrally formed by a magnetic material. The mounting plate portion 2a and the suction plate portion 2b are each in a flat plate shape and extend along directions orthogonal to each other. The suction plate portion 2b is attached to the prospective surface of the frame body portion 11a via the mounting plate portion 2a in a state of protruding inward along the finding direction. In the present embodiment, the suction members 2 are attached to two locations, upper and lower, of the frame body portion 11a. Each suction member 2 is provided such that when the door body 20 is closed, the suction plate portion 2b faces the finding surface facing the a chamber of the vertical frame 24 and can contact the finding surface facing the a chamber of the vertical frame 24 via the contact piece portion 11c1 of the seal member 11c.
[0013] The vertical frame 24 of the door body 20 has a symmetric shape on the left and right. As shown in FIGS. 2 and 3, the frame main body portion 24a, two panel holding piece portions 24b, and two cover holding piece portions 24c are integrally formed. The frame main body portion 24a forms a substantially rectangular hollow cylindrical shape composed of a first finding wall portion (contact portion) 24a1 on the a-chamber side, a second finding wall portion 24a2 on the b-chamber side, an inner peripheral prospective wall portion 24a3 on the inner peripheral side, and an outer peripheral prospective wall portion 24a4 on the outer peripheral side. In the illustrated example, a vertical frame 24 having a frame main body portion 24a with a dimension in the finding direction smaller (substantially 1 / 4) than the dimension in the prospective direction is applied. The panel holding piece portion 24b protrudes inward in the finding direction from the prospective surface on the inner peripheral side of the frame main body portion 24a and holds the panel 21 between them. The cover holding piece portion 24c protrudes outward from both side edge portions on the outer peripheral side of the frame main body portion 24a in a direction gradually approaching each other, and it is possible to detachably dispose the cover member 26 between them. The cover member 26 is, like the vertical frame 24, an extruded profile formed of a metal such as an aluminum alloy, and is formed to have substantially the same longitudinal dimension as the vertical frame 24. In the present embodiment, the main cover plate portion 26a, two outer rib portions 26b, and two inner rib portions 26c are integrally formed to constitute the cover member 26. The main cover plate portion 26a has a flat plate shape with a width substantially the same as the distance between the two cover holding piece portions 24c. The outer rib portion 26b protrudes inward from both side edge portions of the main cover plate portion 26a in a direction gradually approaching each other. The inner rib portion 26c protrudes inward from the surface on the inner peripheral side of the main cover plate portion 26a so as to be substantially parallel to each other. These outer rib portion 26b and inner rib portion 26c are formed to have dimensions that contact the prospective surface on the outer peripheral side of the frame main body portion 24a when the main cover plate portion 26a is disposed between the two cover holding piece portions 24c.
[0014] In the vertical frame 24 at the door end of the door body 20, a magnet 30 is disposed in the hollow portion 24a5 of the frame main body portion 24a. The magnet 30 has a rectangular parallelepiped shape in which the dimension along the finding direction is slightly smaller than the dimension along the finding direction of the hollow portion 24a5, and the dimension along the prospective direction is approximately 2 / 3 of the dimension along the prospective direction of the hollow portion 24a5, and is attached to a portion corresponding to the arrangement position of the suction member 2 in the longitudinal direction of the vertical frame 24.
[0015] More specifically, the magnet 30 is disposed at a position offset toward the a-chamber side in the prospective direction through a notch 24a6 provided in the frame main body portion 24a, and the side surface 30a on the a-chamber side is in contact with the first finding wall portion 24a1 of the frame main body portion 24a. The notch 24a6 opens to the outer peripheral prospective wall portion 24a4 of the frame main body portion 24a and has a rectangular shape larger than the outer shape of the magnet 30, and is formed at a position substantially in the center in the prospective direction. That is, after the magnet 30 is inserted into the hollow portion 24a5 of the frame main body portion 24a through the notch 24a6, it is disposed on the vertical frame 24 in a state of being moved to the a-chamber side. The surface on the inner peripheral side of the magnet 30 and the inner peripheral prospective wall portion 24a3 of the frame main body portion 24a are adhered by an adhesive means 31 such as a double-sided tape. A pressing member 32 provided on the cover member 26 is in contact with the outer peripheral surface of the magnet 30 through the notch 24a6 of the frame main body portion 24a. The pressing member 32 is formed of an elastic material and is interposed between the cover member 26 and the magnet 30 in an elastically compressed state.
[0016] In the vertical frame 24, a holding member 33 is provided at a portion around the magnet 30. As shown in FIGS. 3 and 4, the holding member 33 has two end surface contact restricting portions 33a that contact the upper surface 30b and the lower surface 30c of the magnet 30, and a side surface contact restricting portion 33b that connects between the ends of these two end surface contact restricting portions 33a and contacts the side surface 30d on the b-chamber side of the magnet 30. It is integrally formed of a hard resin similar to the setting block, for example, PVC (polyvinyl chloride). The end surface contact restricting portion 33a of the holding member 33 contacts the upper surface 30b and the lower surface 30c of the magnet 30 disposed in the hollow portion 24a5, thereby preventing the magnet 30 from moving in the vertical direction with respect to the vertical frame 24. The side surface contact restricting portion 33b of the holding member 33 contacts the side surface 30d on the b-chamber side of the magnet 30 disposed offset toward the a-chamber side in the hollow portion 24a5, thereby preventing the magnet 30 from moving in the separating direction with respect to the first finding wall portion 24a1 of the vertical frame 24. As is clear from the figure, the holding member 33 has an outer shape that is accommodated in the notch 24a6 of the frame main body portion 24a in a state of contacting the magnet 30, and is configured such that the dimension along the finding direction is larger than that of the magnet 30, and the portion located on the outer peripheral side is in a state of facing the inner wall surface 24a7 of the opening of the notch 24a6. Between the holding member 33 and the inner peripheral prospective wall portion 24a3 of the frame main body portion 24a, similar to the magnet 30, they are adhered by an adhesive means (not shown) such as a double-sided tape.
[0017] In the fitting configured as described above, when the door body 20 in the open state shown in Fig. 2(b) is moved in the closing direction, as shown in Fig. 2(a), it stops at a position where the finding surface facing the a chamber of the vertical frame 24 abuts against the suction member 2 via the seal member 11c. In this state, the suction member 2 is attracted by the magnet 30 disposed on the vertical frame 24, and due to the magnetic force of the magnet 30, the tip portion of the door body 20 and the suction member 2 provided on the vertical frame 11 are in a proximate state. In other words, the door body 20 is maintained in a closed state. If the door body 20 is moved in the opening direction from this state, the suction state of the suction member 2 by the magnet 30 is released, and as shown in Fig. 2(b) again, the door body 20 can be opened. During these operations, the magnet 30 disposed on the vertical frame 24 is not only adhered to the frame main body portion 24a by the adhesion means 31, but also the vertical movement with respect to the vertical frame 24 and the movement in the direction away from the first finding wall portion 24a1 are blocked by the contact of the holding member 33. Therefore, even when a force is applied to move the magnet 30 with respect to the vertical frame 24 as the door body 20 is opened and closed, it is possible to resist this by contacting the holding member 33, and there is no risk of causing a situation such as the magnet 30 being displaced or falling off from the vertical frame 24. Moreover, since the holding member 33 is provided in the hollow portion 24a5 of the vertical frame 24, there is no risk of affecting the appearance quality of the fitting.
[0018] In addition, in the above-described embodiment, since the end surface contact restricting portion 33a and the side surface contact restricting portion 33b are integrally formed as the holding member 33, it is possible to prevent the complication of the manufacturing work by suppressing the situation where the number of handling parts increases. However, the present invention is not necessarily limited to this, and as in the modification example 1 shown in Fig. 5, the holding member 133a that contacts the upper surface 30b and the lower surface 30c of the magnet 30 and the holding member 133b that contacts the side surface 30d of the magnet 30 may be separate. In this case, it is possible to configure the holding member 133a and the holding member 133b with the same member, and the sharing of parts can be achieved. Note that the same reference numerals are given to the same configurations as those in the embodiment in this modification example 1.
[0019] Further, in the above-described embodiments and Modification 1, the holding member 33 sized to be accommodated inside the opening of the notch 24a6 formed in the vertical frame 24 is applied. However, as in Modification 2 shown in FIGS. 6 and 7, the holding member 233b that abuts on the side surface 30d on the b-chamber side of the magnet 30 may have a portion extending to a position covered by the outer peripheral prospective wall portion 24a4. In this case, if the holding member 233b is configured to abut on the second finding wall portion 24a2, the situation where the magnet 30 moves in a direction away from the first finding wall portion 24a1 can be more reliably prevented. Further, as shown in the drawing, if a holding member 233a having the same shape as the holding member 233b is applied as the holding member that abuts on the upper surface 30b and the lower surface 30c of the magnet 30, the sharing of parts can be achieved. Note that, also in this Modification 2, the same reference numerals are given to the same configurations as those in the embodiment.
[0020] In the above-described embodiments, Modification 1, and Modification 2, the door body 20 having the vertical frame 24 as the facing material is exemplified. However, if the part that becomes the door tip has a hollow part, it is not necessarily required that the facing material has the vertical frame 24. Further, when providing the magnet 30 for the hollow part, in the above-described embodiment, it is configured to pass through the notch 24a6 provided on the prospective surface of the facing material, which is advantageous in terms of workability. However, it is not necessarily required to pass through the notch. For example, it is also possible to dispose the magnet in the hollow part from the end face of the vertical frame 24. Furthermore, although the facing material supported by the hinge 1 so as to be openable and closable with respect to the frame body 10 is exemplified, it can also be applied to those that are opened and closed by moving in the extending direction of the upper frame 12 with respect to the frame body 10. In this case, the magnet may be disposed in the hollow part of the facing material so as to be close to the prospective surface that becomes the door tip of the facing material. In the above-described embodiment of the fitting in which the facing material is supported by the hinge 1 with respect to the frame body 10, the hinge 1 is provided between the vertical frame 11 on the right side and the vertical frame 24 as viewed from the b-room side. However, it may be configured to provide the hinge between the left vertical frame 11 and the vertical frame 24. In this case, in the above-described embodiments, Modification 1, and Modification 2, the magnet 30 may be offset in the reverse direction in the vertical frame 24 that becomes the door tip, and the holding members 33, 133a, 133b, 233a, 233b can be applied as they are.
[0021] Also, in the above-described embodiments, Modification 1, and Modification 2, the holding members 33, 133a, 233a are all brought into contact with the upper surface 30b of the magnet 30. For this reason, not only can the displacement and dropout of the magnet 30 accompanying the opening and closing of the facing material be more reliably prevented, but even if the posture is reversed upside down or a force is applied when transporting the facing material, there is no possibility of causing a situation where the magnet 30 moves upward. However, in the present invention, it is sufficient to provide at least a holding member that contacts the lower surface 30c and the side surface 30d of the magnet 30. Further, although a member facing the inner wall surface 24a7 of the notch 24a6 is applied as the holding member, it is not necessarily required to face the inner wall surface 24a7 of the notch 24a6 as long as it can contact the magnet 30.
[0022] As described above, the fitting according to the present invention includes a facing material that can be opened and closed with respect to a frame body, and due to the magnetic force of a magnet provided inside the door tip of the facing material, when the facing material is closed, the door tip portion of the facing material and a suction member provided on the frame body are maintained in a state of being close to each other. The facing material is provided with a hollow portion at a portion that becomes the door tip, and the magnet abuts against a contact portion that is close to the suction member in the hollow portion when the facing material is in a closed state. A holding member that prevents the magnet from moving downward with respect to the facing material and moving away from the contact portion by abutting against the magnet is attached to a portion around the magnet in the hollow portion of the facing material. According to this invention, since the magnet is disposed in the hollow portion of the facing material and the holding member attached to the hollow portion of the facing material is brought into contact with the magnet, it is possible to prevent relative movement of the magnet with respect to the facing material without affecting the appearance quality.
[0023] Further, the present invention is characterized in that, in the fitting described above, the holding member prevents the magnet from moving upward with respect to the facing material by abutting against the magnet. According to this invention, since the upward movement of the magnet with respect to the door body is prevented, for example, even when the posture is reversed upside down or an external force is applied when transporting the door body, there is no possibility of causing a situation where the magnet moves upward.
[0024] Further, the present invention is characterized in that, in the fitting described above, the facing material includes a vertical frame having a hollow portion at a portion that becomes the door tip, and due to the magnetic force of a magnet provided in the hollow portion of the vertical frame when closed, it is brought close to the suction member through one finding surface of the vertical frame. The vertical frame is provided with a notch that allows the magnet to be accommodated in the hollow portion on a prospective surface on the outer peripheral side, and the holding member is attached to the vertical frame in a state of being interposed between the inner wall surface of the notch and the peripheral surface of the magnet. According to the present invention, the operation of providing a magnet with respect to the hollow portion is facilitated. Further, since the holding member is interposed between the peripheral surface of the magnet and the inner wall surface of the notch, a situation where the position of the holding member is displaced with respect to the vertical frame is prevented, and the relative movement of the magnet with respect to the vertical frame can be more reliably blocked.
[0025] Further, the present invention is characterized in that, in the fitting described above, a cover member is provided on the vertical frame so as to cover the notch, and a pressing member for pressing the magnet against the inner surface of the hollow portion of the vertical frame is provided on the inner surface of the cover member facing the notch. According to the present invention, a situation where the magnet moves in a direction away from the inner surface of the hollow portion of the vertical frame by the pressing member is prevented.
[0026] Further, the present invention is characterized in that, in the fitting described above, the magnet has a lower surface and side surfaces, the holding member abuts against the lower surface and side surfaces of the magnet to prevent downward movement of the magnet and movement in a direction away from the contact portion, and portions that abut against the lower surface and side surfaces of the magnet are integrally formed. According to the present invention, since the holding member that abuts against the lower surface and side surfaces of the magnet is integrally formed, an increase in the number of handling parts can be suppressed.
[0027] Further, the present invention is characterized in that, in the fitting described above, the magnet has a lower surface and side surfaces, the holding member abuts against the lower surface and side surfaces of the magnet to prevent downward movement of the magnet and movement in a direction away from the contact portion, and portions that abut against the lower surface and side surfaces of the magnet are formed separately from each other. According to the present invention, since the holding members that abut against the lower surface and side surfaces of the magnet are separate bodies, there are advantages such as being able to be commonly applied to magnets having different dimensions.
