Abstract

The present invention provides a vertical reel window screen that is small and durable and has excellent operability and safety while opening/closing. A vertical reel window screen uses a cover bracket 4, 3 on the upper and lower ends to transversely pull a housing box 2L, formed by winding a polyester net-like screen 1 into a bobbin 13, into the upper and lower frame rail 32a, 33a, thereby opening the screen 1. A movement stop safety mechanism of the housing box installed in the housing box 2L is used to freely slide or fasten the housing box. The rotation and driving of a handle 21 can release the locking of the rod to the frame rail and enable the housing box to slide, thereby transversely pulling the housing box to a desired position and then releasing the driving handle. The rod instantly clamps the upper and lower guide rail to simply and reliably hold the housing box to a state that will not retract to ensure opening the screen.

V. Description of the invention (l) The technical field to which the invention belongs or single open study The present invention relates to an upright roll-up window that is arranged in a double sliding window window opening and spreads horizontally. The upright roll screens of the known technology have fixed the storage box in which the gauze roll is wound around the winding shaft to the open vertical frame, and then the vertical moving frame with the vertical side of the screen fixed is slid over the open upper and lower frames. Cards are formed by freely pulling horizontally, but they have various problems described below, and there are few practical proposals. That is, it is generally used as a vertical roll screen for a kitchen door, or a horizontal roll window that is opened by pulling the gauze downward after fixing the storage box horizontal frame to the upper end of the window. '' The problem to be solved by the invention-the conventionally known upright roll screen has various problems as shown below. First, "in order to relax the laying of the screen", the winding shaft and the vertical movement frame need to be set to be pulled by the screen. The large cross-section of the bow-shaped strength, the storage and winding of the gauze reel with a large outer circumference will inevitably become a large cross-section. When it is tightly closed with the vertical moving frame, the overall appearance width is large, which not only reduces the opening width but is ugly. 'And it cannot be completely contained in a narrow space such as the estimated size of the horizontal technology aluminum window frame. That is, the cross-sections of the winding shaft and the vertical moving frame are so large that they cannot be compactly and completely accommodated in a narrow space. In addition, when the biasing force of the torsion spring is strengthened to such an extent that the gauze under external pressure will not swell out of the plane, and there will be no gap at the upper and lower ends, the vertical movement frame and the open vertical frame are released. Strong balance at the moment of engagement

440652 V. Description of the invention (2) The vertical moving frame is pulled back to collide with the storage box, making a collision noise, and there is also the risk of deformation or damage to the parts. That is, when the engagement of the vertical moving frame of the gauze opened by the biasing force against the strong biasing force of the torsion spring is released and the open vertical frame is engaged, the vertical moving frame is dangerously pulled back by the torsion spring. " In order to avoid this danger, when the biasing force of the torsion spring is reduced, because the winding shaft cannot be restricted from being reversed, the gauze is stretched out of the plane by the wind pressure, and the gauze is swollen in the center. A gap occurs at the upper and lower ends, which not only damages the insect-proof effect, but also because the gauze remaining on the winding shaft is fully opened. At the same time, the degree of adhesion of the longitudinal edges of the gauze with double-sided tape will be torn, which must be addressed. A method of setting a slit-like hole on the outer periphery of the winding shaft and fixing the gauze edge with a clamping material such as a resin hoop in the hole. The outer diameter of the winding shaft and the outer diameter of the gauze roll become larger. Disadvantages of getting bigger. In addition, the mesh gauze uses a thick vertical thread and a strong tensile strength twisted thread, and a thin horizontal thread is woven in the longitudinal line of the diagnosis. However, the vertical line and the horizontal line are reinforced in the middle part, and the elongation in the direction is small. The closer the end longitudinal line is, the closer it is to the free end, = the elongation is significant. In other words, the yarn is wound on the upper and lower ends of the gauze due to weak tensile strength, and the yarn is unthreaded. In particular, the reel gauze system has a small vertical elongation in which the strong longitudinal line is wound around the winding axis in parallel. However, as mentioned above, when the lateral elongation of the upper and lower ends becomes large, it warps and bends during use. The “rewinding” of the collection also caused a large gap between the upper and lower frames due to bendability, which not only impaired the insect-proof effect, but also loosened the tightness near the upper and lower ends than the middle part. Heat treatment cutting at the lower end of the yarn screen can not prevent the thread from coming off, and the appearance is unsightly. Wang Xian

440652 The description of the five inventions (3) On the other hand, in order to tightly roll the outer diameter of the gauze roll compactly, the winding shaft can be moved so that the gauze roll is supported on the inner wall surface of the storage box to prevent slippage. The method of deflection of the narrow diameter winding shaft, but because the gauze roll is wound tightly in the middle SI, the hardness is not m, that is, as shown above, the upper and lower ends are attached = to this i ^ net of the gauze roll As the upper and lower ends of the winding become looser and looser, the shape, when the gauze is plugged in here, please change the outer periphery into an ellipse to cause obstacles. The slit-shaped exit makes the winding rigidity of the outer ^ net roll positive and the outer diameter of the winding han is positive ρ in the brisk winding action. Because the thicker the thickness of the banknote net, the thicker the gauze roll, the larger the outer diameter. The winding structure with a small thickness is the main reason of a common screen window. ~ It also becomes a large cross-section roll and 'on the above-mentioned gauze side, right Min winding, and the solution to the occurrence of off-line, 2 degrees weak' elongation and easy to roll on the side of the net stitching or continuous continuous pull s γ The polyester hoops and yarns are thickened by adding hoops and wires. The method of making hoops is thick, but the inner diameter of the storage box must also be large, and the gauze rolls _ the outer diameter becomes thinner at the end. The middle part and the middle part become the gauze l. Because the net thickness is thicker than the end part, the winding action is lighter, and the outer diameter of the hoop and the gripper f are different. It is rare to temporarily fix the belt after the operation. The complicated = hem stitching At the same time, the use of double-sided adhesives has reduced the price, which has become the cause of rising prices. 'In itself, the manufacturing operation ^ In addition, the continuous screen of the zipper's teeth screen is generally fixed in the storage box-Qi', y '® It mainly presses horizontally into the vertical frame rail guide grooves on both sides and slides, and hooks the teeth of the gauze-side makeup chain and the guide groove ribs on the card after the upper end of the private frame 440652. The opening and closing action is not smooth due to frictional resistance. Disadvantages. Therefore, the present invention was conceived in order to solve the conventional shortcomings, and its purpose is to provide an upright roll screen, which is small for consumers, and is excellent in durability, operability and safety during opening and closing operations. Means to solve the problem In order to achieve the above purpose, 'provide a double sliding window team "' Also, don't w ^ m-long ^ opening or single window opening, and open the vertical roll yarn laid in the horizontal direction On the outer periphery of the chimney, a gauze reel formed by winding a gauze gauze bonded with a gauze hoop that fixes the side longitudinal edges in the opening longitudinal frame to be freely disassembled, and keeps it freely pulled out, and It is preferable that the flexible winding shaft which is inserted in order to freely rotate the installation of the torsion spring into two bodies is a winding shaft made of synthetic trees such as vinyl or ABS.

At this time, the hand accidentally leaves the driving handle 21, and also accompanies the driving handle 21 by the linking lever 2c to rotate in the original direction with the pressing spring holder. It was lowered, because it was fixed on the upper and lower ends of the storage box 2L, and received the levers 7 and 7b in the lower cover brackets 3 and 4 to immediately clamp the upper and lower frame rails 32 & 3 3a. The storage box 2L emergency stopped, Prevents collision with the vertical frame 34. Called "in this upright reel screen", it can receive a compact winding screen with a light and flexible resin winding shaft 1 3! The screen reel i R is hidden in a small cross section The storage box 2 can be used as a longitudinal moving rod with sufficient strength to improve the storage in a narrow space. The pressure acts on the stretched shop. ^ /, The net 1 also prevents the insect resistance from being damaged due to the gap caused by the upper and lower ends of the screen 1. The glass sliding windows 35R and 35L are fully opened for ventilation or Pull horizontally to the appropriate opening width by fixing the hole of the storage box, 2R to the position where it overlaps with the window frame 36R, 36L, and then fix it statically, or move the window frame 36R, 36L horizontally and store it Boxes 2L and 2R overlap, and the open part can be covered with insect-proof edges by using the fully-opened gauze 1.

At the same time, the ratchet wheel 1 2 engages with the claw 1 9 a of the brake plate 19, and the opening to the screen 1 is restricted due to the restriction.

Page 21 44 06 5 2 V. Description of the invention (19) '-Rotation in direction, wind pressure in the out-of-plane direction, etc., acts on the stretched gauze 1, which can also prevent the gauze roll from rotating and expanding the gauze. , Has the effect of preventing the drum from bowing, and the gauze edge off the upper frame for 3 2 a to produce a gap. In addition, the glass pull / 35R, which was moved on the frame rail 33a while the gauze 1 was laid open, accidentally traversed the upper cover bracket 4 and the lower cover bracket 3, and the upper and lower cover brackets 4, 3 should also function as a stopper, traverse slightly to absorb the impact, and the storage box 2 and the winding shaft 13 are shifted in the pull-back direction. The ratchet 12 is also used to restrict the screen i in the opening direction. The rotation of the rotating winding shaft 13 in the winding direction is not restricted. The biasing force of the torsion spring 14 is used to roll back the loosened gauze 1, so that the gauze is continuously tightly laid 1 °. 8 is the second embodiment of the present invention and its modification. Firstly, in the second embodiment of the present invention shown in FIG. 7, the opening 43 is formed from the opening upper frame 43, and the opening dimensions of the compression springs 45 a and 45 b inserted are made to expand and contract freely. The open frame formed by elastically suspending the flat strip 44a is inserted into the shaft π to which the torsion force is installed. The net yarn = 13 is preferably made of light and flexible synthetic resin such as vinyl chloride or ABS. The hinged shafts are held in the lid brackets 28a, 28b provided above and below the freely rotating storage box 2L. In 8a, the roller 39 is pivotally held on the upper roller bracket 40a in order to contact and roll with the flat bar 28a. The lower frame bracket 28b is pivotally held on the window frame roller 5 rolling on the open lower frame 42. The spring force of the two compression springs 45a and 45b of the hanging flat bar 44 & and the compression spring 4 5 a disposed on the center side of the opening width is set to be weaker than that of the compression spring 45b disposed on the opening end side. . ,, ’

Page 22 440652 V. Description of the invention (20) '' ~ Because it is made of the upright reel screen in the second embodiment of the present invention, the fixation of the storage box 2L is accidentally released, and the winding shaft 13 is inserted in the inserting one! The torsion spring 14 of the inner shaft 17 is also used to hold the flat spring 4 4 a of the compression spring 4 4 ′ under the spring force to hold the roller 39 and the roller 39 in the upper cover bracket 28 a. The window frame roller 5 in the cover 1 exerts a braking effect using friction force. = The spring force of the compression spring 45a provided on the center side of the opening width is set to be greater than that of the compression spring 45a provided with the opening: The collection news is pulled back to the side of the vertical frame 31, the clamping force in the vertical direction is increased, and the pull-back acceleration of the storage box gift is suppressed to decelerate or emergency stop ... You can use the opening spring to hang the compression spring 45a of the flat bar 44a, Adjust the elasticity of 45b. Select the emergency stop or deceleration. The storage box is soft-connected or pulled back to the vertical frame of 3 ft., Especially. Push the emergency stop storage box 2L to the predetermined position by hand; prevent impact pull. In addition, the compression spring & 5 a of the flat bar 4 4 a is held by the frame 4 3 on the opening. The elastic load of 45b is doubled to the window frame roller 5, due to the load of the storage box 2l, and the gauze ^ drum 1R, the load becomes larger than the roller 39, but by making the outer diameter of the window frame roller 5 outside the wheel than the roller 39 The outer peripheral diameter is large, and the rolling friction force of the window frame roller 5 and roller 39 can be set to be approximately the same, and the storage box can be pulled back by the distributed load of the gauze 1 and the like. FIG. 8 shows a shark example of an upright roll screen in Embodiment 2 of the present invention. Specifically, the upper frame 43 is fixed to a length of 5 to 10 cm in the vicinity of the vertical frame 31 on the fixed side of the screen. The flat strip 44 is partially cut into an opening frame formed by reducing the size of the opening slightly, and is inserted into the inner 440652. Fifth of the invention's description (21), the shaft 17 of the torsion spring I 4 is installed. The net-shaped gauze 1 is wound and held to form a winding shaft 13 which is pulled out from the bobbin. The upper and lower ends of the storage box 2L are fixed to be freely rotated. The upper and lower ends are fixedly arranged in the lower cover brackets 28a and 28b. The bracket 2 8b is kept rolling on the lower opening frame 42 and supports the storage box 2L as a freely moving window The frame roller 5 is provided with a roller 39 'which is pivotally held by the roller bracket 40b in the upper cover bracket 28a. The roller 39 is pivotally held on the roller bracket 40a to roll on the upper frame 43 and the flat bar 44. A link lever 2c is connected to the upper end of the roller bracket 40b in the lower cover bracket 2 8b to these roller brackets 40a and 40b, and a fixed link is connected to the roller bracket 40b in the lower cover bracket 2 8b. 2c The front end is connected with the roller bracket 40a in the upper cover bracket 28a to form an integrated freely retractable buffer spring 41. A modified example of the upright roll screen of the second embodiment of the present invention has the above structure. The biasing force of the torsion spring internally connected to the winding shaft 13 is pulled back to the storage box 2L as the storage gauze 1 is wound, and the upper and lower rollers 3 9 compress the buffer spring 41 between the openings narrowed by the flat bar 44 When guided, the braking effect of the rolling friction of the upper and lower rollers 39 in the storage box 2L is used to cause an emergency stop or deceleration, and a soft connection that does not collide with the vertical frame 31.

At this time, 'by adjusting and biasing the torsion spring in the winding shaft 13 and the biasing force of the spring 4 and the rebound strength of the buffer spring 41, you can choose the speed of the storage box or decelerate; The storage box 2L which is stopped on the way may be in close contact with the vertical frame 31, and has the effect of preventing the storage box from colliding with the vertical frame 31 due to the rapid return of the storage box. In addition, the roller bracket 40b may be removed from the structure, and the upper roller bracket 40a is supported by the bottom support of the upper cover bracket 28a and the upper roller bracket 40a.

Page 24 44 06 5 2 V. Description of the invention (22) The lower end of the buffer spring 41 of the body presses the window frame roller 5 and the upper roller 39 into the reduced opening size. Fig. 9 is a third embodiment of the present invention, and is a cross-sectional view of an upright roll screen installed on the indoor side of a kitchen door opening or a single window. First, the 'collection box 2' is drawn horizontally among the four frame groups arranged in the door opening 26, and the gauze 1 is laid on the entire opening. Here, the storage box 2 carries the cover brackets 28a, 28b, which are fixedly arranged on the upper and lower ends of the storage box 2 to guide the card to form a free horizontal pull. The guide groove 34a is fitted into the longitudinal frame 31, and the storage box 2 is pulled horizontally. The engaging device (not shown in the figure) is used to fix the longitudinal frame to be freely disassembled and the gauze 1 is laid. However, when "external pressure on the out-of-plane direction is applied to the gauze 1 so far", the gauze 1 is pulled out of the plane, and the winding shaft 丨 3 is turned in the direction of opening the gauze 1 ", and it is wound. The gauze is also fully opened, and the gauze 1 is greatly swollen in the central part. The lower end of the gauze is detached from the upper and lower frames to cause a gap, which not only damages the insect-proof effect, but also tears the end of the gauze. The double-sided tape of the winding shaft i 3 has the disadvantage that the end of the gauze is detached from the winding shaft i 3, and 2 'as shown in Fig. 10' is the same as the structure of the ratchet 12, the shaft 17, and the winding shaft ^ described above. At the ratchet wheel 12 protruding toward the upper end of the winding shaft 3, the brake plate 27 meshing with the free repulsion is slidably received inside the lid bracket 28a hidden in the upper end of the storage box 2 and the storage box 2 is pulled horizontally and oppositely. The vertical frame 31 is engaged and fixed, and at the same time, the winding shaft 13 is restricted from being reversed. That is, a brake plate 27 is provided in parallel with the cover bracket 28a at the upper end of the storage box 2. The brake plate 2γ is always pushed by the pushing spring 29, and the pawl is separated from the ratchet 12, and the ratchet 12 becomes self-propelled and brakes. Flange head 27b of plate 27

Page 25 440652 V. Description of the invention (23) The guide holes 28c of the cover bracket 28a protrude freely, and the storage box 2—lifts the cover bracket 28a horizontally, and presses against the vertical frame 31, the brake plate 27 The flange head 27b collided with the plate spring 30 fixed to the longitudinal frame 31, and dipped into the guide hole 28c while compressing and urging the spring 29. At the same time, the claw 27a of the brake plate 27 and the ratchet 12 feed, so as to prevent the winding shaft 13 from reversing. The gauze 1 which is once pulled out from the winding shaft 13 can be kept tightly laid without loosening. In addition, the travel error of the cover bracket 28a and the stroke required for the engagement of the brake plate 27 and the ratchet 12 is absorbed by the spring force of the plate spring 30. The upper end of the storage phase 2 tilts the brake plate slightly slower than the lower portion 2 7 The claws 2 7 a also mesh with the ratchet wheel 12 positively. The out-of-plane load acts on the open mesh 1 and also restricts the winding shaft 1 3 and the ratchet wheel 1 2 from turning in reverse, in addition to preventing the screen 1 from becoming large. In addition to bulging, it also has the effect of preventing the longitudinal edges of the gauze 1 from being torn from the winding shaft 丨 3. 11 is an external view of a mesh gauze 1 made of, for example, synthetic resin such as polyacetate, used in Examples 1, 2, and 3 of the present invention. The vertical edge is reinforced by a polyacetate box 38. That is, as shown above, as the mesh gauze is closer to the end longitudinal line and closer to the free end, the longitudinal line and the transverse line lose complementary strength, and the lateral elongation becomes larger. However, in order to prevent the lateral elongation, use acrylic Force or polyurethane-based coating agent will harden the thread 'Untwisting in use, the edge of the $ $ inspection ^ ^ into a single line and presents an unsightly appearance, easy to warp into sex' Under the life song = around the collection in In addition to causing obstacles to the brisk winding movement, the winding shaft 1 3 is susceptible to gaps at the side of the open gauze, which impairs the insect-proof effect, and the mA factor is the main cause of the flare phenomenon.

440652 V. Description of the invention (24) '. Therefore, the extremely thin polyester hoop (thickness of 0.03 ~ 〇. 〇4_) with a mirror finish after aluminum evaporation on both sides of the gauze will have a width of 5 ～ 2〇_After pasting the two sides of the self-knitting net 1, the polyester meshes on both sides were bonded together with the mesh holes of the gauze to strengthen the side of the gauze, but the net thickness was thicker than the middle part. The outer peripheral diameter of the two ends of the yarn bobbin 1R is larger than that of the middle portion. In addition to causing obstacles to the turning movement of the round box in the storage box 2, the internal diameter of the storage box must also be formed into a large size. However, the thickness of the gauze 1 is determined by the outer diameter of the longitudinal line that is thicker than the horizontal line. Generally, the vertical line is a twisted aggregate of ultra-fine polyester threads, which ranges from 55 to 77 denier (the unit of the thickness of the thread). 2, a diameter of 〇3 ~ 〇 4_ a little round 2 wearing face. Therefore, after sticking the gathering hoop 38 from both sides of the gauze, the high-pressure press on the peripheral edge presses the longitudinal line into a flat shape and pastes it, and the thickness is formed into 102 = ~ 0.29mm. The adhesion force of the double-sided polymerization box is used. Consolidate the surroundings of the vertical line, and prevent the vertical line from reverting to a m β i circular line shape. Set the mesh thickness of the reinforced mesh side 2 to the same thickness as the middle part. You can roll it around the winding shaft 13 ^: = 1R is finished into a uniform outer circle # as a whole, which can be conveyed into a smooth winding movement in the storage box 2. Netting = if the shop's gauze net 1 withstands wind pressure and strengthens the tensile strength of the yarn: =: warped into a bow and kept close to the vertical wall of the upper and lower frames, which has the effect of maintaining insect resistance. = Outside: The two sides of the 38 are vapor-deposited for mirror finishing. In addition: stop the increase of the density of the polyacetate texture surface and completely block the ventilation. 胶 The glue of the hoop 38 is in contact with air and moisture to deteriorate. 2; warm fox & radiant heat and solar infrared and ultraviolet radiation

V. Explanation of the invention (25) The effect of the deterioration of the glue The effect of the invention is as shown above. The screen of the present invention can be opened and closed by straight-hand rotation while the screen is opened and closed. The opening and closing of the screens is particularly comprehensive or the durability of the screens is high, and the impact of the rolling and rolling of the upper and lower rollers is used to improve the safety or the unnecessary opening of the screens, so that the insect screen can be used as a hoop to strengthen the edges of the screens In addition to preventing the gauze from falling off at the edges of the gauze, the gauze is the fruit. The vertical roll screen is operated by the side of the drive handle except for the rotation operation of the drive handle, and it is fixed. It also prevents the screen from the impact when it is pulled back, which improves the safety and the insect resistance. The durability of the back window itself, or the improvement of the prevention of its use, is also excellent. In addition to the use of polyester tortuosity, it has a long lasting effect.
