Screen guide frame structure and screen device

Abstract

The screen guide frame structure and screen device mainly comprise a passage (33) provided in the screen guide frame structure, which not only serves to slide one end of a wind-shielding hook (45) into itself when the screen (4) is stored or deployed, but also allows the other end of the wind-shielding hook (45) to be hooked onto the mesh (44) of the screen (4), eliminating the risk of the screen device being blown away from the guide frame (3) when hit by strong winds.

Description

[Technical Field]

[0001] The present invention relates to a screen device, and more particularly to a screen guide frame and a screen device using the screen guide frame. [Background technology]

[0002] Currently, many buildings install screens to prevent mosquitoes and other insects from entering indoors. Hidden screens have become more widely used in recent years because they are easy to store and do not block the view of openings in the building.

[0003] For example, as shown in FIG. 1, the structure of a conventional hidden screen (9) mainly includes a screen (91) and two frame members (92), in which the screen (91) moves between the two frame members (92) for storage and deployment, and the frame members (92) have a storage groove (921) and a guide block (922) at one end of the frame member (92). When the screen (91) is stored, the guide block (922) guides the guide frame (923) to be stored in the storage groove (921) of the frame member (92), as shown by the broken line in FIG. 1. When the screen (91) is deployed, the guide frame (923) moves through the guide block (922). The screen (91) is pulled to the outside of the frame member (92) and is placed so as to lie on the lower end of the screen (91), thereby blocking insects such as mosquitoes from outside from entering the room through the lower end of the screen (91). However, since there is no structure to secure the screen (91) to the guide frame (923), when a strong wind acts on the screen (91), the lower end of the screen (91) is likely to be blown away outside the guide frame (923), creating a gap between the screen (91) and the guide frame (923), allowing external insects such as mosquitoes and dust to enter the room through the gap. As a result, the effectiveness of the conventional concealed screen (9) in blocking insects such as mosquitoes from outside from entering the room is greatly reduced. Summary of the Invention

[0004] The technical means adopted by the present invention is a screen guide frame structure, which has a plurality of pivotable movable members, which are pivotally connected to each other like skewers to form a guide frame, and at least one extension part extends from each pivotable movable member, and the tip of the extension part abuts against another one of the pivotable movable members.

[0005] This is a type of screen guide frame structure, which has a plurality of pivotally movable members that are pivotally connected to each other like skewers to form a guide frame, and at least one elastic pressing device is provided between two adjacent pivotally movable members on the guide frame.

[0006] It is a type of screen guide frame structure, which has a plurality of pivotally movable members, which are pivotally connected to each other like skewers to form a guide frame, and a guide wire fixing member is pivotally mounted on one end of the guide frame, and the guide wire fixing member is provided with at least one screw hole and an engaging protrusion member, and a through hole is provided in the engaging protrusion member at a position opposite the screw hole, and the screw fixing member passes through the through hole of the engaging protrusion member and is then screwed into the screw hole of the guide wire fixing member to be fixed.

[0007] The beneficial effects of the present invention are that the main purpose of the present invention is to provide a screen guide frame structure, which mainly forms a passage in the guide frame that allows one end of the wind-blocking hook to slide in and out when the screen is stored or deployed, and the other end of the wind-blocking hook is caught on the screen mesh, so that the screen will not be blown out of the guide frame when hit by strong winds.

DETAILED DESCRIPTION OF THE INVENTION

[0009] Figures 3 to 5 show a first relatively preferred embodiment of the screen device of the present invention, which comprises a first side frame (1), a second side frame (2), at least one guide frame (3), and a screen (4), wherein the first side frame (1) is adapted to be fixed to an outer frame (8), which can be either the outer frame of a door or window or the outer frame of a screen door, and which can be either a rectangular, lower opening frame, or right opening frame, and as shown in Figure 4, a first guide block (11) is provided at at least one end of the first side frame (1). The second side frame (2) can slide in the outer frame (8), and as shown in FIG. 5, the second side frame (2) is provided with a receiving groove (21), and at least one end of the second side frame (2) is provided with a second guide block (22) communicating with the receiving groove (21). The second guide block (22) is provided with a curved sliding passage (221), and the curved sliding passage (221) has two outlets (222) and (223), one of which (222) is connected to the guide frame ( One of the exits (3) is used for entering the second guide block (22) from the outside, and the other exit (223) is used for the guide frame (3) to enter the receiving groove (21) of the second side frame (2). The guide frame (3) has at least ends (31) and (32), and as shown in FIG. 3, one end (31) of the guide frame (3) forms a connection with the first guide block (11), and the other end (32) of the guide frame (3) enters the receiving groove (21) of the second side frame (2) through the curved slide passage (221) of the second guide block (22).The opposite sides of the screen (4) are fixed to the first side frame (1) and the second side frame (2), respectively. The screen (4) is any one of a cloth-like material, a net-like material, a thin film-like material, a connecting plate-like material, or a material formed by combining at least two of these. The screen (4) is foldable or flat, and the foldable screen (4) can be shrunk after being folded. The screen (4) is formed with at least one mesh (44) passing through it, one end of which is fixed to the first side frame (1) and the other end of which extends into the receiving groove (21) of the second side frame (2) and is then fixed to the end (32) of the guide frame (3), and a plurality of wind-blocking hooks (45) are hooked onto the mesh (44).

[0010] As shown in Figures 6 to 9, the guide frame (3) has a plurality of pivotally movable members (30), and the guide frame (3) is formed by these pivotally movable members (30) pivoting to one another like skewers, and these pivotally movable members (30) are provided with moving grooves (311), and these moving grooves (311) form passages (33) that communicate with one another in the guide frame (3), and each of these pivotally movable members (30) is provided with at least one extension portion (312) on the side facing the passage (33). In this embodiment, extensions (312) are provided on both sides of the pivotally movable member (30) facing the moving groove (311), and the tips of the two extensions (312) abut against another pivotally movable member (30). As a result, when each pivotally movable member (30) pivots and bends, the extensions (312) fit closely together, eliminating gaps between each pivotally movable member (30). This also prevents the mesh (44) extending into the storage groove (21) of the second side frame (2) from being pinched between the pivotally movable members (30), which would hinder the deployment or storage of the screen (4). A recessed chamber (313) is provided on at least one side of the moving groove (311) of the pivotally movable member (30). In this embodiment, it is most preferable that the recessed chambers (313) are provided on two opposing sides of the moving groove (311). The width between the two recessed chambers (313) is wider than the passage (33). Therefore, when the wind-blocking hook (45) is accommodated in the passage (33), the relatively large bottom base (451) of the wind-blocking hook (45) slides and moves within the two recessed chambers (313). As a result, when the screen (4) is acted upon by wind force, the end of the screen (4) close to the guide frame (3) is not likely to be blown away outside the guide frame (3) because the mesh (44) and the bottom base (451) of the wind-blocking hook (45) are accommodated in the recessed chamber (313) of the guide frame (3).In addition, a rail (34) is provided on the path along which the guide frame (3) slides, and at least one protruding rail (341) is provided on this rail (34), and hook grooves (342) are provided on both sides of this protruding rail (341). Furthermore, the guide frame (3) slides on the protruding rail (341) of this rail (34), and the pivotally movable members (30) of the guide frame (3) are provided with engagement tabs (314) that protrude from the sides facing the hook grooves (342) of the rail (34). As the guide frame (3) slides along the rail (34), the engagement tabs (414) of the pivotally movable members (30) of the guide frame (3) can be fitted exactly into the hook grooves (342) of the rail (34), and there is no risk of the guide frame (3) detaching from the rail (34) when sliding along the rail (34) or being pulled into the second side frame (2). As shown in FIG. 6, the second side frame (2) also slides on the rail (34), and at least one roller (212) is provided on the second guide block (22) of the second side frame (2) at a location facing the rail (34). The roller (212) allows the second side frame (2) to slide on the rail (34) more smoothly, thereby saving force.

[0011] As shown in Figures 7 and 8, each pivotally movable member (30) further has at least one side wall portion (301) and a bridge connection portion (302). In this embodiment, the pivotally movable member (30) has two side wall portions (301) and a bridge connection portion (302) provided between the two side wall portions (301). The side wall portion (301) has at least a first portion (303) and a second portion (304). A first recess (305) is provided on one side of the second portion (303), and a second recess (306) is provided on the other side of the second portion (304), and the second recess (306) is used for pivoting the first portion (303) adjacent to the pivotally movable member (30) onto it, and the first recess (305) is used for pivoting the second portion (304) of another pivotally movable member (30). In this embodiment, a pivot shaft 307 is provided in the first recess 305, and a pivot hole 308 is provided in the second recess 306. The pivot shaft 307 and the pivot hole 308 are pivotally connected to the pivot holes 308 and the pivot shafts 307 of the adjacent pivotally movable members 30 in the front and rear, respectively, to form a single elongated guide frame 3. The pivot hole 308 can also be provided in the first recess 305 (not shown), and the pivot shaft 307 can also be provided in the second recess 306. However, in providing these additional shafts, the pivotally movable members 30 can also be pivotally connected to each other like a skewer to form a single guide frame 3, achieving the same effect. In addition, the bottom peripheral edge of the side wall portion (301) is formed in an arc shape, and due to this design, when the guide frame (3) curves and advances through the second guide block (22), the arc-shaped bottom peripheral edge of the side wall portion (301) can fit into the curved sliding path (221), which increases the smoothness of the guide frame (3) curving and advancing through the second guide block (22) and also reduces the noise when the guide frame (3) slides on the second guide block (22).

[0012] As shown in Figures 6 and 8, at least one elastic pushing device (5) is provided between the first recessed portion (305) of the side wall portion (301) of the guide frame (3) and the second portion (304) of another pivotally movable member (30) that pivots against it, and this elastic pushing device (5) has at least one elastic member (51), and this elastic member (51) has a root portion (511) and a free end (512), of which the root portion (511) is provided on the side wall portion (301) and the free end (512) abuts against the second portion (304) of the other pivotally movable member (30). When the guide frame (3) changes from a bent state to an elongated state, the arrangement of this elastic member (51) can reduce the damping force and noise caused by the contact and impact of these pivotally movable members (30).

[0013] 6 and 10, the guide wire fixing member (6) and the mesh adjusting member (7) are pivotally mounted in this order on the end (32) of the guide frame (3) inserted into the receiving groove (21) of the second side frame (2). The guide wire fixing member (6) is provided with at least one screw hole (61) and an engaging protrusion member (62). The engaging protrusion member (62) is provided with a through hole (621) opening toward the screw hole (61). A screw fixing member (63), such as a screw, is connected to one end of the guide wire (64) and then inserted into the engaging protrusion member ( The engaging protrusion member (62) passes through the through hole (621) of the guide wire fixing member (6) and is then screwed into the screw hole (61) of the guide wire fixing member (6) to fix the engaging protrusion member (62) and one end of the guide wire (64) to the guide wire fixing member (6). When the screen (4) is unfolded, the engaging protrusion member (62) can engage with the outside of the outlet (223) of the curved slide passage (221) of the second guide block (22), thereby eliminating the risk that the end (32) of the guide frame (3) will be pulled out of the two guide blocks (22). Based on the above, one end of the guide wire (64) is fixed to the guide wire fixing member (6), and the other end of this guide wire (64) passes through an opening at one end of the storage groove (21) of the second side frame (2) and is then fixed to the outer frame (8); therefore, due to the arrangement of this guide wire (64), when the second side frame (2) pulls the screen (4) to unfold or retract, the guide frame (3) can provide the most preferable linear operation. In addition, in this embodiment, the engaging protrusion member (62) can be detached from the guide wire fixing member (6). Therefore, when removing or maintaining the guide frame (3), the engaging protrusion member (62) must first be removed, and then the guide frame (3) can be pulled away from the second guide block (22). Then, both sides of the screen (4) can be removed from the first side frame (1) and the second side frame (2), respectively, to complete the disassembly of this embodiment. Therefore, the design in which the engaging protrusion member (62) can be detached from the guide wire fixing member (6) brings many advantages to this embodiment, such as convenient disassembly, maintenance, or part replacement.

[0014] As shown in Figure 11, the mesh adjustment member (7) has a through hole (71), and a rotating shaft (72) is further provided inside this through hole (71). A plurality of tooth-like protrusions (721) are provided in an annular shape on this rotating shaft (72). In addition, elastic stopper portions (722) are provided from the inner wall of this through hole (71) toward between these tooth-like protrusions (721). Therefore, the other end of the mesh (44) enters the passage (33) of the guide frame (3) again from the bend in the second guide block (22) and is connected to the rotating shaft (72) again. If the tension of the mesh (44) is inappropriate, the tension of the mesh (44) can be adjusted by turning this rotating shaft (72).

[0015] Figure 12 shows a second relatively preferred embodiment of the present invention, which differs from the first relatively preferred embodiment in that a first guide block (11) is provided at each end of the first side frame (1), and these two first guide blocks (11) are each connected to the end (31) of the guide frame (3), and second guide blocks (22) are provided at both ends of the second side frame (2), and the end (32) of these two guide frames (3) can simultaneously advance from the second guide blocks (22) at both ends of the second side frame (2) into the storage groove (21) of the second side frame (2), and both ends of the guide wire (64) are respectively connected to the guide wire fixing members (6) of these two guide frames (3).

[0016] As shown in Figures 13 and 14, the third embodiment of the present invention differs from the first and second relatively preferred embodiments in that this embodiment has two second side frames 2, four guide frames 3, and a screen 4. Each of the two second side frames 2 has a second guide block 22 at each end. The ends 32 of the four guide frames 3 extend from the four second guide blocks 22 into the receiving grooves 21 of the two second side frames 2. A connecting member 35 is provided between the ends 31 of the two guide frames 3 on the same side. At least one support rod 351 is provided between the two connecting members 35. Therefore, due to the above structural design, this embodiment can be used for a wider screen 4. The support rod 351 can provide the wider screen 4 with stronger wind resistance.

[0017] However, the above drawings and descriptions are merely relatively preferred embodiments of the present invention and do not limit the scope of protection of the present invention. Any changes or modifications with the same effect made by a person skilled in the art based on the features of the present invention should be considered as not departing from the scope of the design of the present invention.
