[0003] [Patent Document 1] JP 2008-156976 A DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0004] In the ventilation device with the above-mentioned configuration, the mold material with the screw holes fixed and the other mold material can move relative to each other in the longitudinal direction, so both ends of the fitting parts of these mold materials are crimped to prevent relative movement. However, if a strong impact is applied during the transportation of the ventilation device, the crimping will come off and the molds will be able to move relative to each other. In addition, the crimped parts are exposed, which makes the appearance poor. [Means for solving the problem]

[0005] The present invention has been made to solve the above-mentioned problems, and is a ventilation device that is incorporated into a window screen and fixed to the vertical frame of the window screen with screws, comprising: a device main body that is constructed by incorporating a plurality of moldings and has an internal ventilation passage; and a screw receiving member that is fixed to both longitudinal ends of a selected molding from the plurality of moldings and has screw holes into which screws from the vertical frame are screwed, wherein a portion of another molding from the plurality of moldings is provided as a specific part extending in the longitudinal direction, notches are formed at both longitudinal ends of the specific part, and ends of the specific part adjacent to the notches are provided as locking ends, and the screw receiving member abuts against each of the locking ends, thereby prohibiting longitudinal movement of the other molding relative to the selected molding. With this configuration, the screw receiving member fixed to the selected mold member hits the locking end of the other mold member, so that the mold members can be reliably prevented from moving relative to each other even if a strong impact is applied during transportation. Also, since there is no need to form a crimping portion between the mold members on both ends of the device body, a good appearance can be maintained.

[0006] Preferably, the notch extends until it reaches an end of the other molded member, and both ends of the specific portion are provided as the engaging ends. According to this configuration, the notch can be easily formed.

[0007] Preferably, the screw receiving members are disposed at both longitudinal ends of the ventilation passage, and the specific portions are protrusions facing the ventilation passage. According to this configuration, the notch can be easily formed.

[0008] In one embodiment, the multiple mold members include a main mold member that accounts for the majority of the device body and a secondary mold member that is placed on top of the main mold member, the main mold member is provided as the selected mold member and the secondary mold member is provided as the other mold member, the ventilation passage is formed between the main mold member and the secondary mold member, the main mold member has a substantially horizontal base wall that defines a bottom surface of the ventilation passage, the ridge is formed on an underside of the secondary mold member, and the screw receiving member has a base portion fixed to the base wall, a standing portion that stands up from the base, and an abutment portion that is provided at an upper end of the standing portion and abuts against the engaging end of the ridge.

[0009] In another aspect, the plurality of mold materials includes first, second and third mold materials, the first mold material being provided as the selected mold material and the second and third mold materials being provided as other mold materials, and the specific portions of the second and third mold materials being positioned adjacent to each other. According to this configuration, since the specific portions of the second and third mold members are disposed close to each other, it is possible to simplify the configuration of the screw receiving member that abuts against the locking ends of these specific portions.

[0010] In a more specific form of the above-mentioned aspect, the first molding is arranged on the outdoor side, the second molding is arranged at an intermediate position, and the third molding is arranged on the indoor side, the first molding is arranged above the second molding and has a partition wall facing the ventilation passage, the second molding has a substantially horizontal base wall that defines the bottom surface of the ventilation passage, and the intermediate portion of the base wall in the indoor / outdoor direction is provided as the specific portion, the third molding has a protruding portion that protrudes toward the outdoor direction along the lower surface of the base wall of the second molding, and the outdoor-side side edge portion of the protruding portion is provided as the specific portion, and the screw receiving member is arranged at both ends of the ventilation passage and has a base that is fixed to the partition wall of the first molding, a hanging portion that hangs down from the base, and an abutment portion that is formed at the lower end of the hanging portion and abuts against the engaging ends of the specific portions of the second and third moldings. Effect of the Invention

[0011] According to the present invention, it is possible to provide a ventilation device that can reliably prohibit relative movement between a plurality of mold members and has a good appearance. [Brief description of the drawings]

[0013] <Ventilation device of the first embodiment> A ventilation device according to a first embodiment of the present invention will be described below with reference to Figures 1 to 7. The ventilation device of this embodiment is an integrated upper frame type, which also serves as the upper frame of a window screen (not shown), and both ends of which are connected to the upper ends of the left and right vertical frames of the window screen. As shown in Figs. 1 and 2, the ventilation device comprises a device body 1 and a pair of screw receiving members 30 disposed at both ends of the device body 1 as main components.

[0014] <Device body> The device body 1 of this embodiment is constructed by assembling together a main section material 10 (selected section material) and a sub section material 20 (other section material) of the same length, both made of extruded aluminum sections, with their ends aligned.

[0015] As shown in Fig. 3, the main mold 10 accounts for the majority of the device body 1, and has a screen body encasement section 4 that encases the glass screen body (not shown) of the window screen, a front wall 12 that rises from the screen body encasement section 4 and faces the inside of the room, a back wall 13 that rises from the screen body encasement section 4 and faces the outside of the room, and a filter housing section 14 formed on the inside of the front wall 12. The approximately horizontal wall that defines the screen body encasement section 4 is provided as a base wall 15 that spans between the front wall 12 and the back wall 13.

[0016] A bearing portion 16 for an operating plate, which will be described later, and a fitting portion 17 are formed at the upper end of the front wall 12. A fitting portion 18 is also formed in the rear wall 12. A number of ventilation openings 12a, 13a are formed in the front wall 12 and the rear wall 13, respectively, aligned in the longitudinal direction of the main mold material 10.

[0017] As shown in FIG. 3, the secondary mold member 20 has mating portions 21 and 22 on the indoor side and the outdoor side, respectively, and also has a mating portion 23 in the middle. The main mold member 10 and the sub mold member 20 are connected by fitting the mating portions 21, 22 of the sub mold member 20 into the mating portions 17, 18 of the main mold member 10 in the longitudinal direction, thereby constructing the device body 1 shown in Figures 1 and 2.

[0018] As shown in Figures 1 and 2, the secondary mold member 20 is disposed so as to bridge between the upper portions of the front wall 12 and the rear wall 13 of the main mold member 10. A ventilation passage 5 is formed between the base wall 15 of the main mold member 10 and the secondary mold member 20. The ventilation passage 5 is connected to the inside and outside of the room via ventilation openings 12a and 13a. The upper part of the rear wall 13 of the main mold member 10 and the sub-mold member 20 form a rail swallowing portion 6 that swallows the upper rail of the window frame.

[0019] As shown in FIG. 1, a filter 7 is removably accommodated in a filter accommodating section 14 of a main mold material 10. An upper end of an operating plate 8 is supported by a bearing section 16 of the main mold material 10 so as to be slidable in the longitudinal direction and rotatable. The operating plate 8 slides in the longitudinal direction by a sliding operation of an operating member (not shown) arranged at one longitudinal end of the device body 1, and during this sliding process, the operating plate 8 rotates due to a cam action between a cam follower 8a at the lower end of the operating plate 8 and a cam member (not shown) fixed to the device body 1, thereby opening and closing the ventilation port 12a. This structure is well known, so a detailed description will be omitted. In addition, the mechanism for opening and closing the ventilation passage 5 can adopt various well-known structures.

[0020] <Screw receiving part> The pair of screw receiving members 30 are made of short aluminum extrusions of the same shape, and are arranged at both longitudinal ends of the ventilation passage 5. As shown in Fig. 3, each screw receiving member 30 has a substantially horizontal base 31, an upright portion 32 that stands up from the middle of the base 31 in the indoor / outdoor direction, and a fitting portion 33 formed on the edge of the horizontal portion that protrudes from the upper end of the upright portion 32 to the outdoor side. The base 31 of the screw receiving member 30 has a thick boss portion 35 on the outdoor side and a connecting portion 36 on the indoor side. A tapping hole 35a having a vertical axis is formed in the boss portion 35. A screw hole 36a extending horizontally in the longitudinal direction is formed in the connecting portion 36.

[0021] The boss portions 35 of the pair of screw receiving members 30 are placed on both ends of the base wall 15 of the main mold material 10, and the screws 9 are passed through the insertion holes 15a of the base wall 15 from below and screwed into the tapping holes 35a of the boss portions 35, thereby fixing the pair of screw receiving members 30 to both ends of the main mold material 10 with the ends nearly flush with each other. In other words, the pair of screw receiving members 30 are fixed so that the outer ends in the longitudinal direction of the pair of screw receiving members 30 nearly coincide with both ends of the main mold material 10 in the longitudinal direction, respectively. The pair of screw receiving portions 30 are connected to both ends of the secondary mold member 20 in the longitudinal direction by fitting the fitting portions 33 of the screw receiving members 30 into the fitting portions 23 of the secondary mold member 20 .

[0022] The ventilation device 1 is placed between the upper ends of the left and right vertical frames of the window screen, and a screw (not shown) that passes through the left and right vertical frames is tapped and screwed into the screw hole 36a of the screw receiving member 30, thereby connecting the ventilation device to the upper end of the vertical frame and forming the upper frame of the window screen. Note that this screw hole may be a female screw.

[0023] <Structure that prevents relative movement of molded parts> The secondary mold member 20 can move in the longitudinal direction relative to the primary mold member 10 simply by fitting it to the primary mold member 10 and the screw receiving member 30. The ventilation device of this embodiment has a structure that prohibits the mold members 10 and 20 from moving relative to each other during the process of transporting it to the work site where it will be assembled into the window screen. This will be described in detail below.

[0024] 3 to 7, the secondary mold material 20 has a protrusion 25 (particular portion) on its lower surface facing the ventilation passage 5. After the secondary mold material 20 is extrusion-molded, both ends of the protrusion 25 are cut away by an amount corresponding to the length of the screw receiving member 30 until they reach both ends of the secondary mold material 20. This cutout is indicated by reference symbol 25a in FIG. 5. Both ends of the protrusion 25 facing the cutout 25a are provided as locking ends 25x that play a role described below.

[0025] The screw receiving members 30 have upper ends of their upright portions 32 that form contact portions 39, and are disposed in the notches 25a of the ridges 25 of the secondary mold member 20. In other words, they are disposed on an extension of the ridges 25. The inner longitudinal ends of the contact portions 39 of the pair of screw receiving members 30 come into contact with the locking ends 25a at both ends of the ridges 25, and the pair of contact portions 39 sandwich the ridges 25, thereby reliably preventing the secondary mold member 20 from moving in the longitudinal direction relative to the main mold member 10, and a device main body 1 in a stably assembled state is obtained.

[0026] In this embodiment, by cutting out both ends of the protrusion 25 formed on the secondary mold member 20, the locking ends 25x can be formed relatively easily.

[0027] <Assembly sequence> The ventilation device having the above-mentioned configuration is assembled in the following order: The main mold member 10 and the secondary mold member 20 are assembled by fitting together, and the pair of screw receiving members 30 are assembled and positioned at both ends of the secondary mold member 20 by fitting together, and then the pair of screw receiving members 30 are fixed to both ends of the base wall 15 of the main mold member 10.

[0028] <Ventilation device of the second embodiment> Next, a ventilation device according to a second embodiment of the present invention will be described with reference to Figures 8 to 12. In this embodiment, some components corresponding to those in the first embodiment are given the same reference numerals, and detailed descriptions thereof will be omitted.

[0029] <Device body> As shown in Figures 8 and 9, the main body 1A of the ventilation device of this embodiment is composed of three mold members, that is, an intermediate mold member 50 (second mold member; other mold member), an outdoor side mold member 60 (first mold member; selected mold member) arranged on the outdoor side of the intermediate mold member 50, and an indoor side mold member 70 (third mold member; other mold member) arranged on the indoor side of the intermediate mold member 50. The intermediate mold member 50 and the outdoor side mold member 60 are made of aluminum extrusion mold member and have the same length, while the indoor side mold member 70 is made of resin extrusion mold member and is shorter than the mold members 50, 60.

[0030] The intermediate form material 50 has a substantially horizontal base wall 51, a hanging portion 52 hanging down from the outside edge of the base wall 51, and an upright wall 53 standing up from the inside edge of the base wall 51. A ventilation opening 53a is formed in the upright wall 53. A bearing portion 54 for supporting an operating plate (not shown) and a fitting portion 55 are formed at the upper end of the upright wall 53. Furthermore, fitting portions 56, 57 are formed at the outside edge and inside edge of the base wall 51, respectively.

[0031] The exterior mold member 60 has a rear wall 61 and a partition wall 62 with a generally U-shaped cross section that extends from the vertical middle of the rear wall 61 toward the interior of the room. A ventilation opening 61a is formed in the lower part of the rear wall 61. The upper part of the rear wall 61 and the partition wall 62 form a rail swallowing section 6. Fitting sections 65, 66 are formed at the upper end of the partition wall 62 and the lower end of the rear wall 61.

[0032] The fitting portions 65, 66 of the outdoor-side mold member 60 are fitted into the fitting portions 55, 56 of the intermediate mold member 50, thereby connecting the two mold members 50, 60. A ventilation passage 5 is formed between the base wall 51 of the intermediate mold member 50 and the partition wall 62 of the outdoor-side mold member 60.

[0033] The indoor side mold member 70 has a front wall 71, a hanging portion 72 hanging down from the lower end of the front wall 71, and a filter housing portion 73 formed on the indoor side of the front wall 71. A ventilation opening 71a is formed in the front wall 71. Fitting portions 74, 75 are formed at the upper and lower ends of the front wall 73.

[0034] The two mold members 50, 70 are connected by fitting the fitting parts 74, 75 of the indoor side mold member 70 into the upper end part of the standing wall 53 of the intermediate mold member 50 and the fitting part 57, respectively. The base wall 51 and the hanging part 52 of the intermediate mold member 50 and the hanging part 72 of the indoor side mold member 70 form the shoji body swallowing part 4.

[0035] <Screw receiving part> The pair of screw receiving members 80 are disposed at both ends of the ventilation passage 5, and are made of extruded aluminum members of the same shape as shown in Figures 8 and 10, and have a base 81, a hanging portion 82 hanging down from the base 81, and a connecting portion 84 formed at the lower end of the hanging portion 82. The screws 9 pass through boss portions 81a formed on the outside of the base 81 and are screwed into the partition wall 62 of the exterior molded member 60, whereby the pair of screw receiving members 80 are fixed to the exterior molded member 60 with both ends flush with each other.

[0036] A screw hole 84a is formed in the connecting portion 84 of the screw receiving member 80. As in the first embodiment, by tapping and screwing a screw (not shown) that passes through the left and right vertical frames into the screw hole 84a of the screw receiving member 80, the ventilation device is connected to the upper end of the vertical frame, forming the upper frame of the window screen.

[0037] <Structure that prevents relative movement of molded parts> The three mold members 50, 60, 70 are capable of relative movement in the longitudinal direction when connected by fitting alone. The ventilation device of this embodiment also has a structure that prohibits relative movement of the three mold members 50, 60, 70. This will be described in detail below.

[0038] 9 and 10, in the base wall 51 of the intermediate mold material 50, a middle portion 51m in the indoor / outdoor direction is provided as a specific portion that plays a role described below. This middle portion 51m has a step, which makes the indoor side of the base wall 51 higher than the outdoor side. At both longitudinal ends of this middle portion 51m, a notch 51a having the same length as the screw receiving member 80 is formed, extending to both ends of the intermediate mold material 50. Both ends of the middle portion 51m facing the notch 51a are provided as locking ends 51x that play a role described below.

[0039] The indoor-side mold member 70 has a protruding portion 78 that protrudes horizontally from the lower end of the front wall 71 toward the outdoor side. This protruding portion 78 is disposed along the underside of the indoor-side portion of the base wall 51 of the intermediate mold member 50. An outdoor-side side edge portion 78e of this protruding portion 78 is provided as a specific portion that plays a role described below. At both longitudinal ends of this side edge portion 78e, a notch 78a that is shorter than the screw receiving member 80 is formed and extends to both ends of the indoor-side mold member 70. Both ends of the side edge portion 78e that face the notch 78a are provided as locking ends 78x that play a role described below. When the intermediate mold member 50 and the indoor side mold member 70 are positioned and connected, the engaging end 51x of the intermediate mold member 50 and the engaging end 78x of the indoor side mold member 70 are aligned in the longitudinal direction.

[0040] The connecting portions 84 of the screw receiving members 80 fit into the notches 51a formed in the middle portion 51m of the base wall 51 of the intermediate form material 50, and serve as a contact portion for the intermediate form material 50. That is, the longitudinal inner ends of the connecting portions 84 of the pair of screw receiving members 80 abut against the engagement ends 51x on both ends of the middle portion 51m, thereby preventing the intermediate form material 50 from moving longitudinally relative to the exterior form material 60.

[0041] The screw receiving member 80 has a protruding portion 85 that protrudes horizontally from the connecting portion 84 toward the indoor side. This protruding portion 85 is along the lower surface of the base wall 51 of the intermediate mold member 50, is at the same height as the protruding portion 78 of the indoor-side mold member 70, and serves as an abutment portion for the indoor-side mold member 70. That is, this protruding portion 85 enters the notch 78a in the side edge portion 78e of the protruding portion 78 of the indoor-side mold member 70, and the longitudinal inner ends of the protruding portions 85 of the pair of screw receiving members 80 abut against the locking ends 78x with the side edge portion 78e of the protruding portion 78m in between, thereby preventing the indoor-side mold member 70 from moving in the longitudinal direction relative to the outdoor-side mold member 60.

[0042] <Assembly procedure for ventilation system> The assembly sequence for the ventilation system having the above-mentioned configuration is as follows: After the three mold members 50, 60, 70 are connected by fitting, a pair of screw receiving members 80 are positioned relative to the mold members 50, 70 (with the connecting portion 84 and the protruding portion 85 inserted into the notches 51a, 78a of the mold members 50, 70), and the base portions 81 of the screw receiving members 80 are fixed to the partition wall 62 of the exterior mold member 60 with screws 9. Note that work holes 59 for screwing in the screws 9 are formed at both exterior ends of the base wall 51 of the intermediate mold member 50 (see FIG. 10).

[0043] The present invention is not limited to the above-described embodiment, and various other embodiments can be adopted. The materials of the multiple molded members of the ventilation device are not limited to those in the above-described embodiment, and various materials can be used. The notches formed at both ends of the particular portion of the mold member do not have to extend to both ends of the mold member. The contact portion of the screw receiving member may be formed shorter than the other portions. The contact portion of the first mold member may serve as both the contact portion that comes into contact with the locking end of the second mold member and the contact portion that comes into contact with the locking end of the third mold member. The multiple mold members and the screw receiving members do not need to be aligned. The ventilation device may be equipped with caps that close both ends of the ventilation passage. In this case, the screw that passes through the vertical frame of the window screen passes through the cap and is screwed into the screw hole of the screw receiving member.

[0044] The ventilation device of the present invention can also be applied to a separate upper frame type. In this case, a door frame swallowing part is formed on the lower side of the device body, and a fitting part that fits into the upper frame of the window door is formed on the upper side.
