Description

Technical Field

[0001] The invention relates to a rolling curtain system, in particular to a manual windproof rolling curtain system. The windproof rolling curtain comprises a curtain cloth which is gathered and unfolded by a winding device. Background Art

[0002] The windproof rolling curtain comprises an upper crossbeam, two side columns, a curtain and a lower edge beam. A winding mechanism is arranged on the upper crossbeam, which can retract and release the curtain. The lower edge beam is connected to the lower end of the curtain.

[0003] The windproof roller shutter system with publication number CN111810041A includes a roller shutter body, a roller shutter drive assembly, a lock beam limit assembly and a lock beam assembly. The roller shutter drive assembly drives the roller shutter body to roll up the roller shutter. The lock beam assembly includes a lower beam body and an electric lock beam component. The lower beam body is arranged at the lower end of the roller shutter body. The electric lock beam component includes an electric lock beam driver and a lock beam part. The electric lock beam driver is arranged on the lower beam body, and drives the lock beam part to lock the lock beam limit assembly.

[0004] The windproof roller shutter with authorization announcement number CN217760827U discloses a windproof roller shutter, including a cover shell, a track assembly, a roller shutter body and a traction rod, wherein two track assemblies are provided, the cover shell is located on the top of the two track assemblies, the traction rod is located between the two track assemblies and below the cover shell, the two ends of the traction rod are respectively slidably connected to the two track assemblies, a reel is rotatably installed inside the cover shell, one end of the roller shutter body is fixed to the reel, and the other end is fixed to the traction rod.

[0005] The above-mentioned windproof roller shutter system uses a motor to drive the lifting and lowering of the roller shutter body. The lifting and lowering of the roller shutter depends on external electricity. In the event of a power outage, the roller shutter cannot be raised or lowered smoothly, resulting in the inability to be used normally in the event of an unexpected power outage. The existing manual roller shutters on the market usually have the following problems with their locking structures: 1. The locking structure is not stable enough and is easily opened by mistake. When the roller shutter is pulled down and locked, it is easy for the roller shutter to accidentally loosen. 2. Some locking structures are relatively stable, but not easy to open flexibly. 3. In addition, generally, in existing roller shutter systems, the fit between the curtain and the lateral columns is not good, and gaps are easily present, which can easily cause the curtain to get stuck in the side columns. Summary of the invention

[0006] In view of the shortcomings of the existing manual roller blinds, the present invention provides a manual windproof roller blind system with a safety lock. By setting a safety lock on the operation button, the locking structure of the safety lock can be flexibly unlocked while ensuring the locking stability of the locking structure and preventing the roller blind from accidentally loosening, so that the user can quickly switch the curtain cloth locking state and unlocking state.

[0112] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are only illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0113] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0114] like Figure 1 and Figure 2 The figure shows the overall structure of the windproof roller shutter system 100. In particular, the windproof roller shutter system 100 in this embodiment is installed with a safety lock 20. The manual windproof roller shutter system 100 with a safety lock comprises two lateral columns 103, a curtain p, an upper beam 101 and a lower beam 102. The upper beam 101 is installed on the target building, the two lateral columns 103 are fixed on both sides of the upper beam 101, and the curtain p is connected to the upper beam 101 in a manner that it can be rolled up or unfolded.

[0115] Specifically, a reel 104 for winding the curtain p is provided in the upper crossbeam 101; the reel 104 is driven to rotate by an external force. The lower end of the curtain p is connected to the lower edge beam 102, and pulling the lower edge beam 102 downward will drive the curtain p to slowly unfold downward, and then cover the door opening surrounded by the upper crossbeam 101 and the lateral columns 103.

[0116] As for the connection relationship between the curtain fabric p, the lower edge beam 102 and the lateral column 103, Figure 5 , Figure 6 and Fig. 9 As shown, the lateral column 103 is fixedly connected by the upper frame a1 and the lower frame a2 by splicing and buckling to form a column body with a rectangular or quasi-rectangular cross section. The side of the column body is open so that the end of the lower edge beam 102 can pass through and be inserted into the beam track h3, so that the lower edge beam 102 can slide up and down along the beam track h3.

[0117] More specifically, the lateral column 103 is provided with a curtain side track h1, a curtain fabric channel h2 and a beam track h3 from inside to outside. The curtain side track h1 is connected with the beam track h3 through the curtain fabric channel h2.

[0118] The side of the curtain p is provided with a positioning edge p1, and the positioning edge p1 of the curtain p moves up and down along the curtain side track h1. One section of the curtain p passes through the curtain channel h2 and slides up and down in the curtain channel h2. Moreover, the curtain channel h2 has a certain width, so that a curtain p of considerable width can be placed in the curtain channel h2, thereby strengthening the track edge of the curtain channel h2 to form a constraint and limit on the curtain p inserted into the lateral column 103, avoiding unnecessary bending and folding of the curtain p in the lateral column 103, and even entanglement with the concave and convex points in the lateral column 103. Ensure the flatness and smooth operation of the curtain p in the lateral column 103.

[0119] like Figures 6 to 8 As shown, the lower ends of the two lateral uprights 103 are provided with locking holes 02. The openings of the locking holes 02 face outwards, and the openings of the two locking holes 02 face oppositely.

[0120] like Figure 7 and Figure 8 As shown, a control button 10 and two locking rods 40 controlled by the control button 10 and extending downward toward the end of the beam are provided on the lower beam 102 .

[0121] The control button 10 is operated to be in the first position, and the locking rod 40 is retracted into the end of the lower beam 102. At this time, the locking rod 40 is in an unlocked state, and the lower beam 102 can move up and down.

[0122] When the control button 10 is in the second position, the locking rod 40 extends out of the end of the lower beam 102 and is inserted into the locking hole 02; at this time, the locking rod 40 is in a locked state, and the two ends of the lower beam 102 are locked with the lateral columns 103 on both sides.

[0123] Furthermore, a safety lock 20 is disposed on the control button 10. In the first state, the safety lock 20 can keep the control button 10 in the first position to prevent the locking rod 40 from being inserted into the locking hole 02. In the second state, the safety lock 20 keeps the control button 10 in the second position to prevent the locking rod 40 from being disengaged from the locking hole 02.

[0124] What needs to be specifically explained about the safety lock 20 is that Figures 13 to 23 As shown, the safety lock 20 includes a lock body 21 and a convex button 22 located at the front side of the lock body 21 , and a lock hole v2 is opened at the front side of the lock body 21 .

[0125] The control button 10 includes a transverse body 11 , a pressing wall 12 located at an outer end of the transverse body 11 , and a locking hook v1 located at an inner end of the transverse body 11 .

[0126] The lock hook v1 on the control button 10 cooperates with the lock hole v2 on the lock body 21 to complete the unlocking of the control button 10 and the safety lock 20 .

[0127] In addition, preferably, a first spring 23 is arranged on the back side of the lock body 21. Pressing the convex button 22 will drive the lock body 21 to move to one side, thereby compressing the first spring 23. At this time, the lock hole v2 will be separated from the lock hook v1 in the front-to-back direction, that is, the lock hole v2 and the lock hook v1 are unlocked. When the external force applied to the convex button 22 is removed, the resilience of the first spring 23 will drive the lock body 21 to reset.

[0128] Preferably, the safety lock 20 further comprises a lock housing, in which the lock body 21 and the first spring 23 are installed. An opening is provided at the front side of the lock housing, and the inner end of the convex button 22 presses against the lock body 21 and the convex button 22 is exposed outward from the opening, so that the user can press the convex button 22.

[0129] More preferably, the control button 10 in this embodiment includes a first control button and a second control button, and the first and second control buttons are respectively distributed on both sides of the safety lock 20. Lock holes v2 are arranged at both ends of the lock body 21 of the safety lock 20 to respectively cooperate with the lock hooks v1 on the first control button and the second control button. The specific structures of the first and second control buttons are consistent, and the structures and cooperative relationship of the lock hook v1 and the lock hole v2 are also consistent.

[0130] In addition, protrusions 24 are provided on both sides of the convex button 22, and the locking hook v1 is located in the lower section area of ​​the side of the transverse body 11 and extends outward to leave a space in the upper section area of ​​the transverse body 11 to facilitate the horizontal placement of the third spring 13.

[0131] Specifically, a third spring 13 is disposed transversely between the transverse body 11 and the protrusion 24 , and two ends of the third spring 13 abut against the inner wall b1 of the upper region of the transverse body 11 and the side wall b2 of the protrusion 24 , respectively.

[0132] In addition, the structural relationship between the locking rod 40 , the slider 30 and the control button 10 includes: the locking rod 40 is connected to the control button 10 through the slider 30 , so that the control button 10 and the locking rod 40 form a linkage relationship.

[0133] Specifically, if Figures 10 to 12 As shown, a top column 15 is provided on the inner side of the lateral body 11 of the control button 10 .

[0134] The slider 30 includes a moving body 31, and a limiting member 32 is disposed on the side of the moving body 31. When the control button 10 cooperates with the slider 30, the top column 15 abuts against the limiting member 32, so that the control button 10 drives the slider 30 to move.

[0135] In addition, a positioning protrusion 33 is arranged on the bottom wall of the moving body 31 of the slider 30, and a positioning groove 03 is opened at the inner end of the locking rod 40. The positioning protrusion 33 is inserted into the positioning groove 03 to complete the connection between the locking rod 40 and the slider 30.

[0136] During actual installation, the inner end of the first locking rod 41 is connected to the first slider 3a, and the inner end of the second locking rod 42 is connected to the second slider 3b. The first slider 3a is connected to the top column 15 on the first control button, and the second slider 3b is connected to the top column 15 on the second control button.

[0137] A connecting rod 50 is connected between the first and second sliders. A second spring 53 is sleeved on the connecting rod 50. Two ends of the second spring 53 are respectively pressed against the inner ends of the first and second sliders.

[0138] When the user presses the first and second control buttons on both sides of the safety lock 20 inward, based on the abutment relationship between the top column 15 and the limiter 32, the two control buttons 10 will drive the two sliders 30 to move relatively inward, and then drive the first and second locking rods connected to the first and second sliders to move relatively away from the corresponding locking holes 02. At this time, the second spring 53 is compressed.

[0139] When the external force applied on the control button 10 is removed, the external force applied on the slider 30 is also removed. At this time, the two sliders 30 will move outwards to reset under the effect of the rebound force of the second spring 53.

[0140] Specifically, a connecting slot w is formed on the side wall of the moving body 31 of the slider 30 , and the connecting slot w includes a passing section c1 and a limiting section c2 . An annular retaining member 51 is formed at both ends of the connecting rod 50 .

[0141] When actually installing, Fig.11 As shown, the annular retaining member 51 is laterally inserted through the segment c1 and passes into the limiting segment c2. The diameter of the limiting segment c1 is smaller than the diameter of the annular retaining member 51 to prevent the annular retaining member 51 from being separated from the limiting segment c2 along the axial direction of the connecting rod 50. That is, the connecting rod 50 is inserted from the side of the connecting notch w during installation. After insertion, an axial limit is formed between the annular retaining member 51 and the inner wall of the limiting segment c1. When the slider 30 moves outward and resets, this limiting structure can effectively prevent the slider 30 from being separated from the connecting rod 50 when moving outward.

[0142] Preferably, if Fig.17 and Fig.18 As shown, the lock hook v1 includes a first inclined surface s1, and a limiting wall is provided at the front end of the lock hole v2, and the limiting wall includes a second inclined surface s2. When the lock hook v1 moves inward, the first and second inclined surfaces cooperate with each other, so that the lock hook v1 can be more easily and smoothly inserted into the lock hole v2. More preferably, the first and second inclined surfaces are smooth inclined surfaces with matching slopes.

[0143] When the lock hook v1 is inserted into the lock hole v2, the lock hook v1 is pressed against the inner wall of the limiting wall, thereby limiting the lock hook from escaping laterally outward.

[0144] In the first state, if Fig.13 , Fig.15 and Fig.16 As shown, the control button 10 is pressed inward to squeeze the third spring 13, and the first and second inclined surfaces cooperate to guide the lock hook v1 to be inserted into the lock hole v2, and the locking rod 40 retracts into the end of the lower edge beam 102, and the lower edge beam 102 can move up and down along the beam track h3.

[0145] In the second state, if Fig.19 , Fig. 20 and Fig.21 , Fig. 22 As shown, the convex button 22 is pressed inward to push the lock body 21 inward to disengage the lock hole v2 from the lock hook v1. At this time, the control button 10 moves outward under the rebound force of the third spring 13, and the locking rod 40 extends out of the end of the lower edge beam 102 and is inserted into the locking hole 02.

[0146] Compared with the prior art, the advantages of the present invention are that a control button 10, a safety lock 20 and a locking rod 40 are arranged on the lower edge beam 102 of the windproof roller shutter system 100, and the locking rod 40 is horizontally distributed in the lower edge beam 102 so as to be movable inward and outward. When the control button 10 is operated, when the control button 10 is in the first position, the locking rod 40 is retracted into the end of the lower edge beam 102, and the lower edge beam 102 is in an unlocked state and can be moved up and down; and the safety lock 20 keeps the control button 10 in the first position to prevent the locking rod 40 from accidentally inserting into the locking hole 02; when the control button 10 is in the second position, the locking rod 40 extends out of the end of the lower edge beam 102 and is inserted into the locking hole 02, so that the roller shutter system is in a locked state; at this time, the safety lock 20 keeps the control button 10 in the second position to prevent the locking rod 40 from being separated from the locking hole 02, thereby ensuring the stability of the locked state. The above technical means can effectively make the rolling shutter system switch the locked or unlocked state of the roller shutter more flexible and free without relying on external power.

[0147] Furthermore, the safety lock 20 includes a lock body 21 and a convex button 22 located at the front side of the lock body, and a lock hole is opened at the front side of the lock body 21; the control button 10 includes a transverse body 11, a pressing wall 12 located at the outer end of the transverse body 11, and a lock hook v1 located at the inner end of the transverse body 11. The lock hook v1 cooperates with the lock hole v2 to complete the locking of the control button 10 and the safety lock 20; the convex button 22 is pressed to make the lock hole v2 away from the lock hook v1 to complete the unlocking.

[0148] The locking structure between the safety lock 20 and the control button 10 is simple and ingenious, and the control cooperation relationship is flexible and direct, so that the unlocking or locking state switching operation of the locking structure is faster and easier, and the maintenance of the two states is also more stable, especially avoiding accidental unlocking in the locked state.

[0149] In addition, the locking rod 40 is connected to the control button 10 through the slider 30, so that the control button 10 and the locking rod 40 form an effective linkage relationship, and ensure that the reciprocating movement of the locking rod 40 and the reciprocating movement of the control button 10 are independent and do not interfere with each other. Specifically, the reset of the two sliders 30 is directly controlled by the second spring 53; and the reset of the control button 10 is directly controlled by the third spring 13, that is, the reset of the control button 10 is constrained so as not to affect the reset of the slider 30.

[0150] In addition, it should be noted that in this embodiment, the pressing wall 12 of the control button 10 is an inwardly concave arc wall, and the curvature of the arc can better match the curvature of a human finger, thereby allowing the control button 10 to be pressed more comfortably and effectively.
