[ detailed description ] embodiments
The following examples are further illustrative and supplementary to the present invention and do not limit the present invention in any way.
As shown in fig. 1 to 7, the main point of the present invention is that the louver blade 10 and the connecting member connecting the louver blade 10 and the cross beam are arranged in an eccentric shape, so that the center line of the louver blade 10 and the center line of the connecting member are not located on the same straight line, and the louver blade 10 can be folded and folded more closely, thereby reducing the size of the folded louver blade, making the folded louver blade more beautiful and occupying less space.
As shown in fig. 1 and 2, the slat eccentric structure of the slat barrier according to the present invention includes a plurality of slats 10, a plurality of first connecting members 20, and a plurality of second connecting members 30. The first connector 20 is used for connecting the louver 10 to the upper barrier beam 40, and the second connector 30 is used for connecting the louver 10 to the lower barrier beam 50. As is well known, the louvres 10 are generally flat sheets having a thickness which is generally less than their height and width. When the louver 10 is installed on a barrier and is spread out flat, the two side surfaces having a large area are generally called front surfaces, the end surface connected to the first connecting member 20 is generally called a top surface, the end surface connected to the second connecting member 30 is generally called a bottom surface, and the side surfaces perpendicular to the front surfaces, the top surfaces, and the bottom surfaces, that is, the side surfaces of the louver 10 are determined by the dimensions in the height and thickness directions thereof. As shown in fig. 3, for convenience of description, the center line of the louver 10 in the thickness direction thereof is defined as a first center line 11, in other words, the first center line 11 is a straight line passing through the midpoints of the upper and lower ends of the side surface of the louver 10. The first centre line 11 is perpendicular to the upper and lower cross members 40, 50 when the slats are in flat use. Similarly, for convenience of description, the center line of the first connecting member 20 in the thickness direction thereof will be referred to as a second center line 21, the center line of the second connecting member 30 in the thickness direction thereof will be referred to as a third center line 31, and the second center line 21 and the third center line 31 are also perpendicular to the upper cross member 40 and the lower cross member 50 when the slat is used in a flat-open state. The first centre line 11, the second centre line 21 and the third centre line 31 are parallel, or substantially parallel, to each other.
As shown in fig. 3, the eccentricity in the present invention means that the second centerline 21 and the first centerline 11 do not coincide with each other, and the third centerline 31 and the first centerline 11 do not coincide with each other, so that the first and second connectors 20 and 30 are offset from the center of the slat 10 in the thickness direction thereof, and the slat 10 can be folded more closely when the slat 10 is folded.
As is well known, when the slat barrier is lifted, as shown in fig. 4, the slats 10 are folded and collected together, and in this process, the upper beam 40 is lifted to a vertical state, the slats 10 are gradually changed from an original state of one slat after another to a state of one slat after another, and are changed from a state perpendicular to the beams to a state of being inclined at a small acute angle with the beams, so that the distance between the lower beam 50 and the upper beam 40 is reduced, and the whole body is folded and collected. During this folding process, the slats 10 are normally folded from a position perpendicular to the cross member toward the direction of approaching the gate due to gravity. In order to fold the louver 10 more, in the present invention, as shown in fig. 5 and 6, the second centerline 21 and the third centerline 31 are preferably eccentrically located on different sides of the first centerline 11. More specifically, the second centerline 21 is preferably offset to one side of the first centerline 11 in the direction in which the louver 10 is folded, and the third centerline 31 is preferably offset to one side of the first centerline 11 in the direction opposite to the direction in which the louver 10 is folded, and the offset distance between the second centerline 21 and the first centerline 11 is preferably equal to the offset distance between the third centerline 31 and the first centerline 11. In the present invention, the distance of the deviation between the second center line 21 and the first center line 11 is 1-3 mm, and the distance of the deviation between the third center line 31 and the first center line 11 is 1-3 mm, and in this embodiment, it is preferable that the distances are all 2 mm. The second central line 21 and the third central line 31 are arranged to deviate from the first central line 11, so that when the louver 10 is folded and folded, the acute included angle between the louver 10 and the upper cross beam 40 and the lower cross beam 50 becomes smaller, the distance between the upper cross beam 40 and the lower cross beam 50 is also smaller, the integral folding and folding of the louver is more compact, and the occupied space is reduced. As shown in fig. 7, data research shows that, for the same-size louver banister, after the louver 10 without the eccentric structure is folded, the acute angle included angle between the louver 10 and the cross beam is 7.5 degrees, and after the eccentric structure of the present invention is used, the acute angle included angle between the folded louver 10 and the cross beam can be as small as 6 degrees. And because the included angle between the louver blade 10 and the crossbeam diminishes, the distance between the upper crossbeam 40 and the lower crossbeam 50 will also diminish, calculate according to the height of the louver blade 10 is 668mm, the louver blade banister without eccentric structure, the distance between the upper crossbeam 40 and the lower crossbeam 50 after its folding is 50.9mm, and the louver blade banister after using eccentric structure, the distance between the upper crossbeam 40 and the lower crossbeam 50 after its folding can be as little as 38.3 mm. Obviously, the shutter plate barrier using the eccentric structure is more compact after being folded, occupies less space and has more attractive appearance.
As shown in fig. 5 and 6, in order to make the second center line 21 and the third center line 31 deviate from the first center line 11, the louver 10 may be provided in a flat plate shape, the first connecting member 20 may be provided to include a flat plate-shaped first flat plate portion 22 and a first eccentric portion 23 connected to the first flat plate portion 22, and the second connecting member 30 may be provided to include a flat plate-shaped second flat plate portion 32 and a second eccentric portion 33 connected to the second flat plate portion 32. The first flat plate 22 is used for being connected with the upper cross beam 40, the second flat plate 32 is used for being connected with the lower cross beam 50, the first eccentric portion 23 is used for being connected with the upper end of the louver 10, and the second eccentric portion 33 is used for being connected with the lower end of the louver 10. The first flat plate 22 and the first eccentric portion 23 may be integrally formed or may be separate members, which may be provided as needed; similarly, the second flat plate portion 32 and the second eccentric portion 33 may be integrally formed or may be separate members. In the present embodiment, the first flat plate portion 22 and the first eccentric portion 23 are preferably separate members, and the second flat plate portion 32 and the second eccentric portion 33 are preferably separate members that are connected together in a known manner. The second center line 21 in the present invention refers to the center line of the first flat plate portion 22 in the thickness direction thereof, and the third center line 31 refers to the center line of the second flat plate portion 32 in the thickness direction thereof.
As shown in fig. 5 and 6, the first eccentric portion 23 is used to connect the louver 10 and the first flat plate portion 22, and offsets a center line of the first flat plate portion 22 in the thickness direction from the first center line 11 of the louver 10. The first eccentric portion 23 comprises a first plug end 231 and a first connection end 232, wherein the first plug end 231 is used for being connected with the louver blade 10, and the center line of the first plug end 231 in the thickness direction is superposed with the first center line 11 of the louver blade 10; the first connection end 232 is used for connecting with the first flat plate portion 22. In order to make the center line of the first flat plate part 22 in the thickness direction, i.e., the second center line 21, deviate from the first center line 11, the center line of the first connection end 232 may be set to deviate from the center line of the first plugging end 231, or the center line of the first connection end 232 may be set to coincide with the center line of the first plugging end 231. When the center line of the first connection end 232 coincides with the center line of the first plugging end 231, the deviation of the center line of the first flat plate part 22 from the first center line 11 can be realized by setting the connection position of the first flat plate part 22 and the first plugging end 231; when the center line of the first connection end 232 deviates from the center line of the first plugging end 231, the center line of the first flat plate portion 22 may or may not coincide with the center line of the first connection end 232, and may be set as required to achieve the same purpose. In this embodiment, the center line of the first connection end 232 is preferably coincident with the center line of the first flat plate 22 and is offset from the center line of the first plugging end 231.
As shown in fig. 5 and 6, the second eccentric portion 33 is used to connect the louver blade 10 and the second flat plate portion 32, and offsets the center line of the second flat plate portion 32 in the thickness direction from the first center line 11 of the louver blade 10. The second eccentric portion 33 comprises a second inserting end 331 and a second connecting end 332, wherein the second inserting end 331 is used for connecting with the louver blade 10, and the center line of the second inserting end 331 along the thickness direction is coincident with the first center line 11 of the louver blade 10; the second connection end 322 is used for connecting with the second flat plate portion 32. In order to offset the thickness-direction center line of the second flat plate portion 32, i.e., the third center line 31 from the first center line 11, the center line of the second connecting end 332 may be offset from the center line of the second mating end 331, or the center line of the second connecting end 332 may be aligned with the center line of the second mating end 331. When the center line of the second connecting end 332 coincides with the center line of the second inserting end 331, the deviation of the center line of the second flat plate part 32 from the first center line 11 can be realized by setting the connecting position of the second flat plate part 32 and the second inserting end 331; when the center line of the second connecting end 332 deviates from the center line of the second inserting end 331, the center line of the second flat plate portion 32 may or may not coincide with the center line of the second connecting end 332, and may be set as required to achieve the same purpose. In this embodiment, the center line of the second connecting end 332 is preferably coincident with the center line of the second flat plate portion 32 and is offset from the center line of the second inserting end 331.
Therefore, the louver eccentric structure of the louver barrier gate is formed, the first central line 11 of the louver 10 in the thickness direction is set to deviate from the central lines of the first connecting piece 20 and the second connecting piece 30, so that when the louver 10 is folded and folded, the acute included angle between the louver 10 and the cross beam is reduced, the distance between the upper cross beam 40 and the lower cross beam 50 is reduced, and finally, the overall structure of the louver barrier gate when being folded is more compact, the louver barrier gate occupies less space, and the effect of improving the appearance is achieved.
