Description

Technical Field

[0001] This utility model relates to curtains, and more particularly to a serpentine curtain trolley device, and a serpentine curtain using the trolley device. Background Technology

[0002] Snake blinds are a popular window covering product in recent years, becoming a new favorite in home design due to their unique wavy pleats and minimalist aesthetic. Compared to ordinary curtains, snake blinds present a smooth, regular wave shape like a snake's body when unfolded, making them more aesthetically pleasing (the spools are hidden by the curtain fabric, making them more visually appealing), and they also offer better light blocking.

[0003] Traditional serpentine blinds are typically fastened by trolleys mounted on a track and intermittently fastened to the installation straps. The blinds are then sewn onto the installation straps. However, in current technology, when the trolleys are pulled up, if it's a double-opening serpentine blind, the first trolley will touch the middle of the curtain on both sides. After the touch, the motor retracts a short distance to mark the end of its travel (if it doesn't retract, there will be noise each time it touches the middle). This results in gaps between the two parts of the serpentine blind that are in contact. Furthermore, because the trolleys are highly mobile, these gaps can easily widen, leading to insufficient light blocking and affecting the user experience. If it's a single-opening serpentine blind, the first trolley also cannot reach the position where the curtain covers the end of the track, resulting in light leakage.

[0004] To address the aforementioned issues, existing technologies include serpentine blinds such as the multi-purpose curved track trolley for an electric serpentine blind disclosed in Chinese Patent Application No. 202321290494.2, and a trolley device for a double-opening serpentine blind disclosed in Chinese Patent Application No. 202320359714.6. These devices utilize a long arm (trolley frame) on the first trolley of one side of the curtain fabric, allowing the end of the curtain fabric on that side to overlap with a portion of the curtain fabric on the other side, thereby reducing the gap between the two sides of the curtain fabric. However, this method of extending the trolley on one side results in asymmetry between the two sides of the serpentine blind, still affecting the user experience. Furthermore, if used for a single-opening blind, the extended portion of the trolley (protruding along the track extension direction) can collide with the exterior of the blind, such as a wall, affecting normal use. Utility Model Content

[0005] The first technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a serpentine curtain trolley device that improves light blocking and user experience, and ensures normal use.

[0006] The second technical problem to be solved by this utility model is to provide a serpentine curtain that uses the above-mentioned serpentine curtain trolley device.

[0007] The technical solution adopted by this utility model to solve the first technical problem mentioned above is as follows: a serpentine curtain trolley device, comprising a trolley body and a first connecting member for fixing the curtain fabric to the serpentine curtain, the trolley body having a first end and a second end opposite to each other; characterized in that:

[0008] The trolley also includes a boom disposed between a first end and a second end of the trolley body. The boom is disposed near the first end and includes a connecting part and a bending part. The connecting part is fixed to the trolley body, and the bending part bends away from the trolley body from one end of the connecting part toward the first end. The bending part gradually tilts away from the trolley body toward the second end, and the first connecting member is disposed on the bending part.

[0009] By positioning the hanging arm between the two ends of the trolley body, and closer to one of the ends, such as the first end (which is the end furthest from the hanging wheel during installation), the trolley device will not collide with the outside of the curtain. At the same time, the hanging arm has an inclined bend, and the first connector for fixing the curtain is placed on the inclined bend. This allows the end of the curtain to tilt after passing through this point, thereby making it easier to cover the area not covered by the trolley and improving the light-blocking performance.

[0010] Preferably, the boom is positioned near the bottom of the trolley body.

[0011] To maintain the shape of the serpentine curtain fabric at the portion corresponding to the trolley, according to one aspect of the present invention, the trolley further includes a second connector for fixing the serpentine curtain fabric, the second connector being disposed at a second end of the trolley body.

[0012] To maintain the shape of the serpentine curtain fabric at the portion corresponding to the trolley, according to one aspect of the present invention, the trolley further includes a second connecting member for fixing the serpentine curtain fabric. The second connecting member is detachably connected to a second end of the trolley body via an adapter. By providing the adapter, different lengths of adapters can be used to adapt to tracks of different lengths.

[0013] Preferably, the first connector is a buckle, hook, or ring.

[0014] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: a serpentine curtain, including a track, characterized in that: the track is provided with a serpentine curtain trolley device as described above, the trolley is slidably engaged with the track, the serpentine curtain also includes a curtain fabric, the end of the curtain fabric fixed on the trolley passes through and exceeds the first connecting member by the side of the bending portion away from the second end.

[0015] Preferably, the angle between the bent portion and the longitudinal direction of the track is α, and satisfies: 30°≤α≤85°

[0016] Furthermore, the trolley has two symmetrically arranged trolleys, with the first ends of the trolley bodies of the two trolleys close to each other. This allows for the adaptation of double-opening curtains. The symmetrical arrangement of the two sets of trolleys in the trolley device enables the fabric of the serpentine curtain to be symmetrically arranged on the trolley device. The first connector forms a symmetrical overlapping portion when closed, which better improves light-blocking performance and enhances the user experience.

[0017] Furthermore, each trolley corresponds to a curtain, and the portion of the curtain that extends beyond the trolley is an extension section. When the serpentine curtain is closed, the two extension sections abut against each other.

[0018] Compared with the prior art, the advantages of this utility model are as follows: By setting the hanging arm between the two ends of the trolley body and close to one of the ends, such as the first end (which is the end away from the hanging wheel during installation), the trolley device will not collide with the outside of the curtain. At the same time, the hanging arm has an inclined bend, and the first connector for fixing the curtain is set on the inclined bend, which allows the end of the curtain to tilt after passing through this point, thereby making it easier to cover the area not covered by the trolley and improving the light blocking performance. By symmetrically arranging the two sets of trolleys of the trolley device, each trolley is equipped with a first connector and a second connector, so that the curtain of the serpentine curtain can be symmetrically arranged on the trolley device. The first connector forms a symmetrical overlapping part when closed, which can better improve the light blocking performance and enhance the user experience. Attached Figure Description

In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0027] See Figures 1-6 A serpentine curtain includes a track 1, a pulley assembly, and a curtain fabric 3. The pulley assembly comprises two symmetrical combinations extending along the length of the track 1. Each combination includes a pulley 21 and a roller 22. There is one pulley 21 and one or more rollers 22. The rollers 22 of the two sets are respectively located on the side of the pulley 21 away from the other set. Each pulley slides in conjunction with the track 1. The pulley assembly with the above structure is used for double-opening curtains. When used for single-opening curtains, only one combination of pulley 21 and roller 22 is required.

[0028] The trolley 21 includes a trolley body 211, a boom 212 mounted on the trolley body 211, a first connecting member 213, and a second connecting member 214. The roller 22 includes a roller body 221 and a third connecting member 222 mounted on the roller body 221. The structures of the first connecting member 213, the second connecting member 214, and the third connecting member 222 can be the same or different, as long as they can be fixed to the curtain 3. Optional connecting members can be such as latches, hooks, or rings, similar to existing technologies.

[0029] The trolley body 211 has a first end 2111 and a second end 2112 opposite to each other along the length of the track. The first end 2111 is the end away from the pulley 212 and also the end close to the other trolley 21, while the second end 2112 is the end close to the pulley 212 and also the end away from the other trolley 21. The boom 212 is fixed to the trolley body 211, preferably fixed to the front of the trolley body 211, i.e., the side facing the indoor user in the installed state, and is located near the first end 2111. Optionally, the boom 212 is located near the bottom of the trolley body 211, such as flush with the bottom of the trolley body 211. A first connector 213 is located on the boom 212, and a second connector 214 is located on the trolley body 211, so that the first connector 213 is close to the other set of trolleys 21, while the second connector 214 is located on the side of the trolley body 211 away from the other set of trolleys 21. The third connector 222 is located at the bottom of the hanging wheel body 221. The fixing method between each connector and the curtain 3 is the same as the prior art, that is, the back of the curtain 3 (the side facing the outside in the installed state) is provided with a mounting strap that passes through each connector and is fixed.

[0030] In this embodiment, the boom 212 is set separately from the trolley body 211. Alternatively, the boom 212 can also be part of the trolley body 211.

[0031] The second connector 214 can be directly disposed at the second end 2112 of the trolley body 211, or it can be detachably connected to the second end 2112 of the trolley body 211 via an adapter 215. Thus, the length of the adapter 215 can be selected according to the length of the track 1, thereby adapting the trolley device to the track 1.

[0032] There are two curtains 3, each corresponding to a set of trolley devices. The curtains 3 are fixed to the trolley devices via a first connector 213, a second connector 214, and a third connector 222. The curtains 3 have protrusions forming curved sections 31 between adjacent first connectors 213, between adjacent first connectors 213 and second connectors 214, between second connectors 214 and third connectors 222, and between adjacent third connectors 222. The protrusion directions of adjacent curved sections 31 are opposite; that is, if one curved section 31 protrudes towards the indoor user, then the two adjacent curved sections 31 protrude towards the outdoor direction. Preferably, the cross-section of the curved section 31 is arc-shaped, and the curtain 3 as a whole forms a wave shape.

[0033] The boom 212 includes a connecting portion 2121 and a bending portion 2122, which are preferably integrally formed. The connecting portion 2121 can be fitted and fixed to the trolley body 211, such as by locking with screws. The bending portion 2122 bends away from the front of the trolley body 211 (i.e., towards the indoor user) from the end of the connecting portion 2121 toward the other set of trolleys 21, and the bending portions 2122 of the two trolleys 21 gradually move away from each other from the end near the front of the trolley body 211 toward the side away from the front of the trolley body 211. The first connecting member 213 of the trolley 21 is provided on the bending portion 2122. The boom 212 does not extend beyond the first end 2111 of the trolley body 211, so that it will not collide with the outside of the curtain when used for a single-opening curtain.

[0034] The angle between the bend 2122 and the length direction of the track 1 is α, and optionally, 30°≤α≤85°, so as to better tighten the curtain 3.

[0035] The end of the curtain 3 furthest from the trolley 21 terminates at the third connector 222 of the hanging wheel 22 furthest from the trolley 21. The end of the curtain 3 fixed to the trolley 21 passes through and exceeds the first connector 213 from the side of the second end 2112 of the bend 2122 furthest from the trolley body 211. This extended portion is the extension 32. Due to the bend 2122 on the hanging arm 212, the curtain 3 bends after passing the first connector 213. The extended sections 32 formed by the bend will approach and abut each other when the serpentine curtain is closed, which can block light and make both sides symmetrical and beautiful.
