Detailed Description
Fig. 1A is an external schematic view of a combined body of an opening and closing door structure according to an embodiment of the present invention. FIG. 2A is a schematic view of the embodiment of FIG. 1A with the open and close door structure open. Fig. 3 is a perspective view of the region a in fig. 1A. For clarity, the upright 170, the base 180, the fixing rod 190 and the door side panel fixing buckle F are omitted from fig. 2A. In addition, the external schematic view of fig. 1A means a schematic view seen from the outside of the main body toward the direction of the opening and closing door structure.
Referring to fig. 1A and fig. 2A, in the present embodiment, the door opening and closing structure 100 includes a door leaf 110, a cross bar 120, a zipper 130 and a pull rope 140. The door leaf 110 is, for example, a foldable door leaf. The crossbar 120 is connected to the lamella 110. The crossbar 120 is connected to a zipper 130. In detail, the crossbar 120 has a connection buckle 122. The connecting button 122 of the cross bar 120 is fastened with a zipper 130. A pull cord 140 is attached to the cross bar 120. The opening and closing door structure 100 is adapted to be combined with the main body 50 to shield or open a space (not shown) inside the main body 50. In the present embodiment, the main body 50 is, for example, a tent. In other embodiments, the main body 50 may be a facility requiring a door opening and closing function, such as a factory, an outdoor large facility, etc., and the present invention is not limited thereto.
In particular, in the present embodiment, the connector links 122 of the crossbar 120 are adjacent to opposite ends 124 and 126 of the crossbar 120. The connecting buckle 122 is buckled on the zipper head 132 of the zipper 130. The door leaf 110 further comprises a sleeve 112, the sleeve 112 is located at the bottom of the door leaf 110, and the cross bar 120 is sleeved in the sleeve 112. That is, the crossbar 120 is connected to the lamella 110 by the sleeve 112. The sleeve 112 is used to fix the cross bar 120 so that the cross bar 120 and the sleeve 112 do not move relative to each other. The pull cord 140 is tied to the first position P1 and the second position P2 of the sleeve 112. The first and second locations P1 and P2 are adjacent to opposite ends 1122, 1124 of the sleeve 112, respectively. That is, the draw string 140 is connected to the crossbar 120 by being tied to the sleeve 112 over which the crossbar 120 is sleeved. In addition, the distance from the first point P1 to the end 1122 of the sleeve 112 and the distance from the second point P2 to the other end 1124 of the sleeve 112 are both 300 millimeters (mm), but the invention is not limited thereto.
On the other hand, the opening and closing door structure 100 further includes a pulley block 150 and a door side plate 160. The pull cord 140 is looped around the pulley block 150 and attached to the cross bar 120. The door side pieces 160 are positioned at both sides of the door piece 110. The door piece 110 and the door side piece 160 are connected by a zipper 130. In detail, the pulley block 150 includes a plurality of fixed pulleys 152, and for example, two fixed pulleys 152, which is not limited by the invention. The fixed pulleys 152 are located on the door leaf 110, and are located on both sides above the door leaf 110, for example. In the present embodiment, the cross bar 120, the zipper 130, the pull rope 140 and the pulley block 150 are located at the outer side (i.e. the outer side of the main body 50) relative to the door leaf 110, for example, but the invention is not limited thereto.
In more detail, one embodiment of the fixed pulley 152 is, for example, a double-grooved fixed pulley. A portion of the pull cord 140 may extend downwardly through a groove (not shown) in the fixed pulley 152 surrounding the left side in fig. 1A and 2A and tied to the first point P1 of the sleeve 112. Another portion of the pull cord 140 may extend downward through a groove (not shown) in the fixed pulley 152 at the right of fig. 1A and 2A and be tied to the second P2 of the sleeve 112, and another portion of the pull cord 140 extends from the fixed pulley 152 at the right of fig. 1A and 2A to another groove (not shown) in the fixed pulley 152 at the left of fig. 1A and 2A and further to one side S1 of the opening and closing door structure 100. Therefore, the door opening and closing structure 100 of the present embodiment can be suitable for a single person to operate on the same side S1. The present invention is not limited to the embodiment of the fixed pulley 152.
Referring to fig. 1A and 2A, a user (not shown) can apply a tension T to the pull cord 140. The pulley assembly 150 is used to change the transmission direction of the tension T applied to the pulling rope 140, that is, when a user provides a downward oblique tension T to the pulling rope 140 at, for example, one side S1 of the opening and closing door structure 100, the tension T is changed in its transmission direction (for example, the direction opposite to the gravity direction G) by the pulley assembly 150, so that the pulling rope 140 adjacent to the door leaf 110 provides an upward tension T to at least a portion of the door leaf 110 and the crossbar 120.
Referring to fig. 2A again, when a user applies a tension T to the pulling string 140, and the tension T is greater than the weight of the cross bar 120 and at least a portion of the flap 110, the cross bar 120 is pulled by the pulling string 140 along the extending direction E of the zipper 130 and pulls apart at least a portion of the zipper 130. At least a portion of the door leaf 110 is moved by the cross bar 120 in a folding manner along the extending direction E to form an opening O, so that the outside is communicated with the inside of the main body 50. On the other hand, referring to fig. 1A again, when the tension T applied by the user is smaller than the gravity of the cross bar 120 and at least a portion of the door leaf 110, the cross bar 120 moves along the gravity direction G and closes at least a portion of the zipper 130, and the door leaf 110 is moved along the gravity direction G by the cross bar 120 to reduce the opening O (shown in fig. 1A as closing the opening O to shield the inside of the main body 50. that is, the door leaf 110 and the door side panel 160 are integrally connected by the zipper 130. in other situations, a portion of the door leaf 110 and a portion of the door side panel 160 are connected by the zipper 130 to achieve the effect of reducing the opening O). In this embodiment, the crossbar 120 may simultaneously open (or close) at least a portion of the zippers 130 on both sides of the flap 110 to form (or close) the opening O.
It should be noted that, in the embodiment, since the pulling rope 140 is respectively tied to the first position P1 and the second position P2 of the sleeve 112, when the user applies the tension T, the tension T only needs to be at least a part of the door leaf 110 and half of the gravity of the cross bar 120, so as to drive at least a part of the door leaf 110 to fold upwards to form the opening O. In other words, the door opening and closing structure 100 of the present embodiment has a labor saving effect.
In view of the above, the door opening and closing structure 100 of the present embodiment pulls up (or lowers) the cross bar 120 by the pulling rope 140, and the pulling rope 140 drives the cross bar 120 to open (or close) at least part of the zipper 130 so as to make the door leaf 110 form (or close) the opening O of the door opening and closing structure 100, compared to the prior art, the door opening and closing structure 100 of the present embodiment does not need to open the entrance of the main body 50 (e.g. a tent) in an up-and-down manner, and the operation manner of forming the opening O is simple and convenient.
Referring to fig. 1A again, in the present embodiment, the door opening and closing structure 100 further includes a plurality of positioning portions L and hooks H. The positioning portion L is, for example, a positioning ring. These positioning portions L are provided along the extending direction E of the cord 140. The positioning portion L is used to position the pull cord 140. For example, referring to fig. 1A and fig. 2A, when a user applies a tension T to the pulling rope 140 to fold at least a portion of the door leaf 110 and the cross bar 120 upwards to form the opening O, if the user thinks that the size of the opening O has reached its requirement, the user can position the pulling rope 140 in the positioning portion L (in fig. 2A, the pulling rope 140 is, for example, the positioning portion L positioned at the top), and the pulling rope 140 is suitable for being tied to the first hook H1 to achieve the function of fixing the pulling rope 140. At the same time, the size of the opening O is also defined by the above-described operation. Therefore, the opening and closing door structure 100 of the present embodiment moves smoothly and has an aesthetic shape.
Referring to fig. 1A and fig. 3, in the present embodiment, the main body 50 further includes a pillar 170 and a base 180. The door opening and closing structure 100 further includes a fixing rod 190 and a door side piece fixing buckle F. The pillar 170 is used to support the door side panel 160. The pillar 170 is disposed on the base 180. The fixing rod 190 penetrates through the base 180, and the fixing rod 190 is fixedly arranged on the door side piece 160 to prevent the door side piece 160 from swinging left and right. Therefore, the slider 132 of the slide fastener 130 does not smoothly move up and down as the door side piece 160 swings left and right. The door side piece fixing buckle F is fixedly arranged on the door side piece 160 and the fixing rod 190. The door side piece fixing fastener F is fixed to the door side piece 160 by, for example, welding. The fixing rod 190 is fixed on the base 180 in the above manner, so the door opening and closing structure 100 of the present embodiment is stable, firm and convenient to disassemble and assemble.
It should be noted that, the following embodiments follow the contents of the foregoing embodiments, descriptions of the same technical contents are omitted, reference may be made to the contents of the foregoing embodiments for the same element names, and repeated descriptions of the following embodiments are omitted.

Referring to fig. 1B and fig. 2B, in the present embodiment, a switch gate structure 100a is similar to the switch gate structure 100 of fig. 1A and fig. 2A, and the main differences are: the switch door structure 100a further includes a hole Q. The crossbar 120, the zipper 130, a portion of the pull cord 140, and the pulley block 150 of the opening and closing door structure 100a are located on the inner side (i.e., inside the body 50) with respect to the lamellae 110. Another portion of the pull cord 140 extends through the aperture Q and out of the body 50 (e.g., outside a tent, the portion shown in phantom). In this way, the door opening and closing structure 100a of the present embodiment can prevent the influence of rain and low temperature (i.e., anti-freezing effect) on the pull chain 130, the cross bar 120 and the pulley block 150.

Fig. 4B is an internal schematic view of the area B in fig. 4A when the movable member is not yet docked with the crossbar. Fig. 4C is a perspective view of fig. 4B. Fig. 4D is an internal schematic view of the area B in fig. 4A when the movable member is docked with the crossbar. Fig. 4E is a perspective view of fig. 4D. Fig. 4F is a schematic perspective view illustrating a fixed rod and a cross rod connected in a door opening and closing structure according to another embodiment of the present invention. In addition, the external schematic view of fig. 4A means a schematic view viewed from the outside of the main body toward the direction of the opening and closing door structure, and the internal schematic views of fig. 4B and 4D means schematic views viewed from the inside of the main body toward the direction of the opening and closing door structure.
Referring to fig. 4A to fig. 4E, in the present embodiment, the switch gate structure 100b is similar to the switch gate structure 100 of fig. 1A and fig. 2A, and the main differences are: in this embodiment, the switch door structure 100b further includes a plurality of second hooks H2, a plurality of connecting portions C, and a plurality of movable members R, and the second hooks H2, the connecting portions C, and the movable members R are respectively located at two sides of the switch door structure 100b, and the number of the second hooks, the connecting portions C, and the movable members R is two, for example, but the invention is not limited thereto. The connecting portion C is, for example, a spiral ring, but the invention is not limited thereto. The cross bar 120b has a plurality of openings 121, and the number of the openings 121 is two, for example, but the invention is not limited thereto. These openings 121 are located on either side of the cross bar 120 b. One end CE1 of the connecting portion C is inserted through the slider 132 of the slide fastener 130. The other end CE2 of a connecting part C is inserted into one end HE1 of a second hook H2. The other end HE2 of a second hook H2 is inserted into an opening 121. That is, in the opening and closing door structure 100a of the present embodiment, the zipper 130 is connected to the crossbar 120b through the connection portion C, the second hook H2 and the opening 121.
Referring to fig. 4A, fig. 4B and fig. 4C, in the door opening and closing structure 100B of the present embodiment, when the cross bar 120B moves to the bottom of the door leaf 110 due to gravity, the door leaf 110 can be folded toward the inside of the main body 50 to a position corresponding to the fixing rod 190B. Referring to fig. 4B to fig. 4E, in the present embodiment, a movable member R has a sliding groove G. The fixing rod 190b has a first accommodating space (not shown) and a clamping portion 192. The engaging portion 192 is a screw, for example, but the invention is not limited thereto. A movable member R movably penetrates through the first accommodating space. The positioning portion 192 is disposed through the fixing rod 190b to the sliding groove G so that the movable member R can move relative to the fixing rod 190b in the extending direction of the sliding groove G. When the fixing rod 190B is not yet abutted to the cross bar 120B (fig. 4B and 4C), a user (not shown) can rotate the movable member R in the first accommodating space by an angle, so that the latching portion 192 abuts against a portion of the movable member R except the sliding groove G, and the movable member R does not move relative to the fixing rod 190B. Referring to fig. 4A, 4D and 4E again, in more detail, in the present embodiment, the cross bar 120b further has a snap Q1. The movable member R further has a second receiving space (not shown) and a snap hole Q2. When the fixing rod 190b is abutted to the cross bar 120b (fig. 4D and 4E), the cross bar 120b movably penetrates through the second accommodating space until the snap-fastener Q1 on the cross bar 120b is engaged with the snap-fastener hole Q2 of the movable member R, and the cross bar 120b and the movable member R are less likely to generate relative movement. In this way, the door opening and closing structure 100b of the present embodiment, with the above configuration, when the door sheet 110 shakes due to an external force (for example, wind force), the torsion of the zipper head 132 due to the shaking can be reduced. In detail, since the fixing rod 190b is abutted with the cross bar 120b, at least a part of the torsion to the zipper head 132 can be shared by the fixing rod 190b, so that the zipper head 132 is less prone to damage.
As mentioned above, when the door opening and closing structure 100b of the present embodiment lowers the cross bar 120b through the pulling rope 140 so that the door leaf 110 closes the opening O, the movable member R is adapted to be pulled out from the first accommodating space of the fixing rod 190b and butt against the cross bar 120 b. In this way, the door opening and closing structure 100b of the present embodiment, with the above configuration, when the door sheet 110 shakes due to an external force (for example, wind force), the torsion of the zipper head 132 due to the shaking can be reduced. In detail, since the fixing rod 190b is abutted with the cross bar 120b, at least a part of the torsion to the zipper head 132 can be shared by the fixing rod 190b, so that the zipper head 132 is less prone to damage.
Referring to fig. 4F, the fixing rod 190c of fig. 4F is substantially the same as the fixing rods 190 and 190b of the door opening and closing structure, and the main differences are: in this embodiment, one end of the fixing rod 190c further has a Y-shaped opening Y, and the opening direction of the Y-shaped opening Y is upward. When the cross bar 120b moves to the bottom of the door 110 in the gravity direction G by gravity, a part of the cross bar 120b (the end of the cross bar 120 b) may be disposed in the Y-shaped opening Y, and when the cross bar 120b is pulled upward by an external force, the cross bar 120b is less likely to be separated from the Y-shaped opening Y and swing back and forth, and the above-mentioned arrangement may also reduce the torsion of the slider 132, so the slider 132 is less likely to be damaged.
Fig. 5 is an internal schematic view of a switch door structure according to another embodiment of the present invention. Further, the internal schematic view of fig. 5 means a schematic view seen from the inside of the main body toward the opening and closing door structure.
Referring to fig. 5, the switch door structure 100c of the present embodiment is substantially similar to the switch door structure 100b of fig. 4A, and the main differences are: the switch door structure 100c also includes a hole Q. The crossbar 120, the zipper 130, a portion of the pull cord 140, and the pulley block 150 of the opening and closing door structure 100c are located on the inner side (i.e., inside the body 50) with respect to the lamellae 110. Another portion of the pull cord 140 extends through the aperture Q and out of the body 50 (e.g., outside a tent, the portion shown in phantom). In this way, the door opening and closing structure 100c of the present embodiment can prevent the influence of rain and low temperature (i.e., anti-freezing effect) on the pull chain 130, the cross bar 120 and the pulley block 150.
Fig. 6A is an external schematic view of a combination body of a door opening and closing structure according to another embodiment of the present invention. Fig. 6B is a schematic view illustrating a disassembly process of the detachable zipper of fig. 6A.
Referring to fig. 6A, the switch door structure 100d of the present embodiment is substantially similar to the switch door structure 100 of fig. 1A, and the main differences are: the door opening and closing structure 100d further includes an adhesive portion AP, which is implemented in a manner of a tape. The zipper is in the form of a removable zipper 130'. The adhesive portions AP are located at both sides of the detachable zipper 130'. Referring to fig. 6B, the detachable zipper 130 'is connected to the door side piece 160 through the adhesive portion AP, and in more detail, the detachable zipper 130' is adhered and fixed to the door side piece 160 through the adhesive portion AP. When the detachable zipper 130 'is damaged by an external factor (e.g., wind), the user may open the adhesive part AP to replace the damaged detachable zipper 130'.
Fig. 7A is an external schematic view of a combined body of a door opening and closing structure according to another embodiment of the present invention. Fig. 7B is a schematic view illustrating a disassembly process of the detachable zipper of fig. 7A.
Referring to fig. 7A, the switch door structure 100e of the present embodiment is substantially similar to the switch door structure 100d of fig. 6A, and the main differences are: the opening and closing door structure 100e further includes a sub-zipper SZ. The sub-zippers SZ are positioned at both sides of the detachable zipper 130'. Referring to fig. 7B, the detachable zipper 130' is connected to the door side panel 160 via a sub-zipper SZ. When the detachable zipper 130 'is damaged by an external factor (e.g., wind), the user may pull down the sub-zippers SZ located at both sides thereof to replace the damaged detachable zipper 130'. It is worth mentioning that, since the thickness of the sub-zipper SZ of the opening and closing door structure 100e is thinner than that of the adhesive portion AP of the opening and closing door structure 100d, when the cross bar 120 is moved upward by the tension T, the flap 110 can be pulled up relatively smoothly.
In summary, the door opening and closing structure of the embodiment of the invention pulls up (or down) the cross bar through the pulling rope, and the pulling rope drives the cross bar to pull open (or close) at least part of the zipper so as to enable the door leaf to form (or close) the opening of the door opening and closing structure.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
