Description

Technical field

[0001] The invention is related to a curtain, in particular, a curtain lower rail noise reduction structure provided on an end cover of the lower rail that can form a buffer silencer for both ends of the lower rail. Prior technology

[0002] The curtain, which is commonly known, will be provided with a top rod, a drape and a lower rail, the upper and lower rails of the drape are respectively equipped with the top rod and the lower rail, the top rod can be fixed on the wall or other fixed position, the drape can be folded assembled on the top rod, and movably adjust the position of the drape; However, the lower rail is only fixed under the drapery, so when the drapery forms a swing when subjected to wind or when folded, the lower rail will also be driven by the drapery and sway back and forth. In order to reduce the impact sound produced by shaking, a buffer device will be provided on the lower rail, as disclosed in the case of invention Patent No. I779814.

[0003] However, because the lower rail is most easily in contact with the wall (glass) during the shaking process is at the two ends of the lower rail, that is, the position where the second-end cover is set up, so when the buffer device is set in the lower rail or the side position of the second-end cover, the buffer device is not provided at the two ends of the lower rail The cushioning effect of the Xizhi buffer device is not good, and, although the Xizhi buffer device is located on the side of the end cover, it usually uses a solid structure, resulting in easy sound when impacted, and, using injection molding combined with the end cover, its processing is also relatively cumbersome and manufacturing cost is higher. Contents of the invention

[0004] One object of the present invention is to provide a buffer disposed on the outermost side of the lower rail that can effectively reduce the sound produced in the event of a collision.

[0005] One of the purposes of the present invention is to provide a buffer space that allows the buffer piece to have a collapse deformation after impact, avoiding sound on impact.

[0006] To achieve the above purpose, the invention provides a curtain lower rail noise reduction structure comprising: A lower rail, the top of which can be connected to a curtain, has a front side and a rear side; The two end caps are disposed at both ends of the lower rail. Each end cap also has a front side and a rear side. The rear side of the two end caps and the rear side of the lower rail face the same direction. A set of connecting parts is provided on the rear side of each end cap. Two buffer components are respectively disposed on the outer side of the joint of the two end caps. The two buffer components are respectively disposed on the outer side of the joint of the two end caps. The two buffer components are respectively disposed on the outer side of the end caps. The buffer is deformed by force, so that when the buffer is deformed, it can be squeezed into the buffer space.

[0007] Preferably, the buffer zone of the two buffer components is provided with two arms at the top and bottom, the two arms are connected to the connecting part, and the length of the two arms constitutes the buffer space.

[0008] The noise reduction structure for a curtain bottom track provided by the present invention can form a good buffering effect at both ends of the bottom track through the two buffer members. When the bottom track is shaken by external force, the two ends that are most likely to collide with foreign objects can be buffered by the buffer effect of the two buffer members, which can prevent the bottom track or end cap from directly hitting foreign objects and form a good anti-collision effect, and reduce the sound generated during the impact.

[0010] Please refer to Figures 1 to 4, which are preferred embodiments of the curtain lower track noise reduction structure provided by the present invention. This is a curtain assembly 10, comprising:

[0011] A top rod 20, as shown in Figure 1, can be fixed in a predetermined position, such as the ceiling or window frame, to form a fixed position. A retracting device or a pulling device can also be installed on the top rod 20 for control.

[0012] A curtain 30, as shown in Figure 1, is a single piece with one end fixed to the top rod 20. The height of the curtain 30 can be adjusted by rolling it up or down relative to the top rod 20.

[0013] The lower rail 40, as shown in Figure 3, is a long strip-shaped rod with its top end connected to the curtain 30. The lower rail 40 has a front side 41 and a rear side 42, respectively. An opening 43 is formed at both ends of the lower rail 40, and a connecting part 431 is provided in the center of the opening 43. A screw hole 432 is formed in the center of the connecting part 431.

[0014] The two end caps 50, as shown in Figures 3 and 4, are assembled at both ends of the lower rail 40, i.e., outside the two openings 43. Each end cap 50 has a front side 51 and a rear side 52. The front side 51 of the end cap 50 and the front side 41 of the lower rail 40 face the same direction, so the rear side 52 of the end cap 50 and the rear side 42 of the lower rail 40 also face the same direction. The rear side 52 of the end cap 50 is a rear sidewall 521, and each of the two rear sidewalls 521 has a connecting portion 53. In this embodiment, each connecting portion 53 is a double through hole 531. A groove 522 is provided on the inner side of the rear sidewall 521, opposite to the position of the two through holes 531. Two wings 54 are provided on the two end caps 50 facing the two openings 43. The two wings 54 are positioned opposite each other outside the connecting part 431. The two end caps 50 are provided with a connecting hole 55. A screw 551 can be inserted through the connecting hole 55 and screwed into the screw hole 432, so that the two end caps 50 can be assembled and fixed on the lower rail 40. The two end caps 50 define a length L1 and a width W1 on the rear side 52.

[0015] The two buffer members 60, as shown in Figures 3 and 4, are made of a soft, deformable material and are respectively disposed at the center of the outer side of the assembly portion 53 (i.e., the rear side surface 52) of the two end caps 50, so that the two buffer members 60 protrude from the two end caps 50 and the lower rail 40. The lateral width W2 of the two buffer members 60 is approximately equal to the lateral width W1 of the two end caps 50, and the vertical length L2 of the two buffer members 60 is less than the vertical length L1 of the two end caps 50. The two buffer members 60 are respectively provided with a connecting portion 61 that is connected to the assembly portion 53. In this embodiment, the connecting portion 61 is provided with two protruding buttons 611, which are embedded in the through holes 531 of the assembly portion 53, and the ends of the protruding buttons 611 are disposed in the grooves of the rear side wall 521. Within 522, the protruding button 611 does not protrude from the rear sidewall 521; each of the two buffer members 60 is provided with a buffer zone 62, which is located on the outermost side of the two buffer members 60. Each of the two buffer zones 62 has an arm 63 at its upper and lower ends, which is connected to the connecting part 61, so that the buffer zone 62 can deform under force. The two arms 63 create a gap between the connecting part 61 and the buffer zone 62, and a hollow buffer space S is formed between the connecting part 61 and the buffer zone, so that the buffer zone 62 can be squeezed into the buffer space S when it is deformed under force; the buffer zone 62, the two arms 63 and the connecting part 61 form a rectangle, and the length of the two arms 63 is shorter than the length of the buffer zone 62.

[0016] During operation, please refer to Figures 5 to 8. When the curtain assembly 10 is not under load, the lower rail 40 will remain stationary, as shown in Figure 5, maintaining a distance from the exterior wall W. When the curtain 30 is swayed by wind or swayed due to force during the rolling process, the lower rail 40, due to its weight and its location at the bottom of the curtain 30, will sway back and forth. During this swaying, the two ends of the lower rail 40, i.e., the locations where the end caps 50 are installed, are most likely to come into contact with the exterior wall W. As shown in Figure 6, when the two ends of the lower rail 40 are about to collide with the exterior wall W, the two buffers 60 are located at the two ends. The rear side 52 of the end cap 50 protrudes from the two end caps 50. Therefore, when the end of the lower rail 40 is impacted, the two buffer members 60 will be impacted first. At this time, because the buffer member 60 is made of soft and deformable material, the buffer 62 will first bear the impact force and be squeezed and deformed into the buffer space S. The buffer 62 can withstand the impact force through deformation. Because the buffer member 60 is soft and the buffer space S is used, no sound is generated when impacted. Furthermore, because the space of the buffer space S makes the buffer 62 more protruding, the two end caps 50 or the lower rail 40 are less likely to be impacted and generate sound. In addition, as shown in Figures 7 and 8, when the lower rail 40 collides with the outer wall W with one end, the buffer member 60 will also be the position that contacts the outer wall W the fastest, and it can still produce a noise reduction effect. In addition, the rectangular buffer member 60 can also make the force uniform and can withstand deformation evenly.

[0017] The noise reduction structure for the curtain bottom track provided by the present invention has buffers that can be set at both ends of the bottom track to withstand most of the impact and form a buffer. Furthermore, the buffer is set to protrude from the end cap to generate compression deformation, thereby reducing the sound generated during the collision.

[0018] The above-described embodiments are merely illustrative of the technical means of the present invention and are not intended to limit it. Any equivalent modifications made to the present invention should be considered within the scope of protection of the present invention. The curtain bottom track noise reduction structure of the present invention is an original structure in this field and has improved practical effectiveness; therefore, this application is filed in accordance with the law.
