Description

Technical Field

[0001] This utility model relates to the field of curtain technology, and in particular to a curtain and a curtain mounting bracket. Background Technology

[0002] When installing curtains, since there is a certain error in the inner width of the window frame, in order to better fit the inner width of the window frame and achieve a stable and effective installation, existing no-drill curtains usually have a retractable movable tensioning mechanism at one end of the top beam. The retraction and extension of the movable tensioning mechanism can well fit the width of the window frame and achieve tension and fixation.

[0003] However, the existing curtains described above have the following drawbacks during installation: Since the curtain width is usually slightly smaller than the length of the top beam, and a movable tensioning mechanism is required at one end of the top beam, when this mechanism extends and presses against the corresponding side of the window frame, the distances from the two ends of the top beam to the corresponding side of the window frame will differ. This results in asymmetrical gaps between the two sides of the curtain and the corresponding side of the window frame, leading to significant differences in light transmission. Furthermore, the gap is larger on the side with the movable tensioning mechanism, resulting in excessive light transmission. Consequently, the curtains' light-blocking effect is poor. Utility Model Content

[0004] The technical problem to be solved by this utility model embodiment is to provide a curtain mounting bracket to effectively solve the problem of asymmetrical light transmission or excessive light transmission on both sides of the curtain.

[0005] The further technical problem to be solved by this utility model embodiment is to provide a curtain that effectively solves the problem of asymmetrical light transmission on both sides of the curtain or excessive light transmission.

[0006] To solve the above-mentioned technical problems, the present utility model first provides the following technical solution: a curtain mounting bracket, comprising:

[0007] beam;

[0008] A movable tensioning mechanism assembled at one end of the crossbeam includes a pressing member that can extend and retract along the length of the crossbeam and an adjusting assembly for driving the pressing member to extend and retract. The outer end of the pressing member and the opposite end of the crossbeam respectively abut against the vertical frame edges on opposite sides of the top of the window frame to fix the crossbeam to the top of the window frame; and

[0009] A transfer rack, installed on the crossbeam, is used to fix the upper beam of the curtain to it.

[0010] Furthermore, the curtain mounting bracket also includes a cover plate assembled on the crossbeam and correspondingly covering the movable tensioning mechanism.

[0011] Furthermore, the top of the cover plate is pivotally connected to the top of the inner side of the crossbeam, and the cover plate has a length and height sufficient to completely cover the crossbeam, the movable bracing mechanism, and the upper beam.

[0012] Furthermore, the top of the inner side of the crossbeam is formed with an upward-facing groove and through-holes at both ends. The cover plate includes a main body, a connecting rib protruding from the top of the main body to one side, and a rotating shaft integrally formed on the outer edge of the connecting rib. The rotating shaft slides into the groove from one end of the groove.

[0013] Furthermore, the crossbeam is a cylindrical body with an internal cavity, the movable tensioning mechanism is assembled in the cavity and the pressing member extends from the corresponding end face of the crossbeam, the side wall of the crossbeam is provided with an adjustment hole for the adjustment tool to pass through to operate the adjustment component, and the cover plate also covers the adjustment hole accordingly.

[0014] Furthermore, the transfer rack includes:

[0015] A base fixed to the bottom wall of the crossbeam, the bottom surface of the base having two L-shaped hooks symmetrically arranged at predetermined intervals. Each L-shaped hook includes a vertical plate connected to the bottom surface of the base and a horizontal plate extending from the bottom edge of the vertical plate. The vertical plate has a snap-fit ​​hole. The horizontal plates of the two hooks extend towards each other, and the two hooks together form a hanging groove.

[0016] The bottom of the slider is fixed to the top surface of the upper beam of the curtain. The top of the slider has elastic hooks on opposite sides. The top of the slider slides into the hanging groove from the entrance at one end of the hanging groove and is supported by the horizontal plate of the two L-shaped hooks and is correspondingly engaged in the buckle hole by the elastic hooks.

[0017] Furthermore, the transfer rack also includes an elastic retainer. A baffle is formed on the bottom wall of the base at the end of the hanging groove away from the entrance / exit. The elastic retainer is placed in the hanging groove and its two opposite ends elastically press against the baffle and the slider respectively, thereby positioning the slider at the position where the elastic hook abuts against the end wall of the buckle hole away from the baffle.

[0018] Furthermore, the adjustment component includes:

[0019] A box assembled at one end of the crossbeam;

[0020] A double-ended screw is assembled inside the box and fixed axially relative to the box. The two opposite ends of the double-ended screw are respectively provided with a first external thread and a second external thread with opposite helical directions, and at least one end is exposed from one side of the box as an operating end.

[0021] Two nuts that are screwed into the first and second external threads at both ends of the double-ended screw and move synchronously towards or away from each other in the axial direction under the drive of the double-ended screw;

[0022] Two push rods are symmetrically arranged with respect to the midpoint of the distance between the two nuts and perpendicular to the axis of the double-ended screw. One end of each push rod serves as a connecting end, corresponding to one of the two nuts, and moves synchronously under the drive of the two nuts. The other end of each push rod serves as a driving end, hinged to the corresponding pressing member. When the connecting end moves synchronously with the nuts, the driving end drives the pressing member to slide accordingly. Adjacent sides of the driving ends of the two push rods are also provided with first locking teeth that maintain mutual engagement when the two push rods rotate under the drive of the nuts; and

[0023] Two support rods are symmetrically arranged relative to the symmetrical face. One end of each support rod is pivotally connected to the housing via a first pivot, while the other end of the two support rods is pivotally connected to the two nuts via a second pivot. The central axes of the first and second pivots are perpendicular to the axial direction of the double-ended screw. The adjacent sides of the pivot ends of the two support rods are also provided with second locking teeth that keep them meshing with each other when the two support rods rotate around the first pivot.

[0024] Furthermore, the pressing member includes:

[0025] A pressing seat is hinged at one end to each of the two push rods. The pressing seat has a sliding groove that extends along the sliding direction of the pressing seat and has an opening at the end away from the push rod. The groove walls on opposite sides of the sliding groove are also provided with elongated limiting holes that extend parallel to the sliding groove. The groove has a guide hole on the groove end wall near the push rod.

[0026] A retractable and slidable pressing block is assembled within the slide groove and extends from the opening of the slide groove at one end. The pressing block has corresponding limiting hooks on its opposite sides, which are positioned within the limiting slots to limit the sliding stroke of the pressing block. A guide rod protrudes from the pressing block and is inserted into the guide hole.

[0027] A reset elastic element is disposed in the slide groove and its two ends respectively abut against the pressing block and the groove end wall away from the opening of the slide groove.

[0028] On the other hand, this utility model embodiment also provides a curtain, including a top beam, a curtain body with its top end connected to the top beam, and a curtain mounting bracket as described in any of the above claims, wherein the top beam is fixed to the transfer frame of the curtain mounting bracket.

[0029] After adopting the above technical solution, the present utility model embodiment has at least the following beneficial effects: by using the curtain mounting bracket provided by the present utility model embodiment to install the curtain, the movable tensioning mechanism at one end of the crossbeam can be adjusted to firmly tension and fix the crossbeam to the top of the window frame, and then the upper beam of the curtain can be fixed to the mounting bracket. Thus, the upper beam length and curtain width can be designed more appropriately according to the inner width of the window frame, which can effectively ensure that the gaps between the two ends of the upper beam and the two sides of the curtain and the corresponding vertical frame of the window frame are symmetrically distributed and relatively narrow, avoiding the problems of uneven light transmission on both sides and excessive light transmission on one side.

[0041] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the following illustrative embodiments and descriptions are only used to explain the present utility model and are not intended to limit the present utility model. Moreover, the embodiments and features in the embodiments of the present application can be combined with each other unless otherwise specified.

[0042] like Figures 1-11 As shown, an optional embodiment of this utility model provides a curtain mounting bracket 1, comprising:

[0043] 10 crossbeams;

[0044] A movable tensioning mechanism 12 is assembled at one end of the crossbeam 10. The movable tensioning mechanism 12 includes a pressing member 120 that can extend and retract along the length of the crossbeam 10, and an adjusting assembly 122 for driving the pressing member 120 to extend and retract. The outer end of the pressing member 120 and the opposite end of the crossbeam 10 respectively abut against the vertical frame 40 on opposite sides of the top of the window frame 4, thus fixing the crossbeam 10 to the top of the window frame 4; and

[0045] The transfer rack 14 is set on the crossbeam 10 and is used to fix the upper beam 3 of the curtain to it.

[0046] By using the curtain mounting bracket 1 provided in this embodiment of the invention to install curtains, the movable tensioning mechanism 3 located at one end of the horizontal beam 1 can be adjusted to firmly and securely fix the horizontal beam 1 to the top of the window frame 4. Then, the upper beam 3 of the curtain can be fixed to the transfer frame 14. This allows for a more suitable design of the length of the upper beam 3 and the width of the curtain body 5 based on the inner width of the window frame 4. This effectively ensures that the gaps between the two ends of the upper beam 3 and the two sides of the curtain body 5 and the corresponding vertical frame 40 of the window frame 4 are symmetrically distributed and relatively narrow, avoiding uneven light transmission on both sides and excessive light transmission on one side. Moreover, the curtain mounting bracket 1 has good compatibility and can be widely used for various traditional curtains with upper beams, such as Roman blinds, honeycomb blinds, Venetian blinds, and sun and moon blinds. No other structural modifications are required to the traditional curtains; quick assembly can be completed simply by assembling the upper beam 3 of the traditional curtains onto the transfer frame 14.

[0047] In another optional embodiment of this utility model, the curtain mounting bracket 1 further includes a cover plate 16 assembled on the crossbeam 10 and correspondingly covering the movable tensioning mechanism 12. In this embodiment, by providing the cover plate 16, the movable tensioning mechanism 12 can be correspondingly covered, thereby effectively preventing light from passing through the gaps at the movable tensioning mechanism 12, which is beneficial to improving the overall light-blocking effect of the curtain.

[0048] In another optional embodiment of this utility model, such as Figures 1 to 5 As shown, the top of the cover plate 16 is pivotally connected to the top of the inner side of the crossbeam 10. The cover plate 16 has a length and height sufficient to completely cover the crossbeam 10, the movable support mechanism 12, and the upper beam 3. In this embodiment, by reasonably setting the length and height of the cover plate 16, the crossbeam 10, the movable support mechanism 12, and the upper beam 3 can be effectively covered, thereby improving the overall aesthetic appearance. In addition, the top of the cover plate 16 is pivotally connected to the crossbeam 10, which allows the cover plate 16 to be easily rotated open when needed for maintenance and adjustment of the crossbeam, the movable support mechanism 12, and the upper beam 3.

[0049] In another optional embodiment of this utility model, such as Figure 4 and Figure 5 As shown, the top of the inner side of the crossbeam 10 has an upward-facing constricted groove 100 with through-holes at both ends. The cover plate 16 includes a main body 160, a connecting rib 162 protruding from the top of the main body 160 to one side, and a pivot 164 integrally formed on the outer edge of the connecting rib 162. The pivot 164 slides into the constricted groove 100 from one end. In this embodiment, the constricted groove 100 is formed on the top of the crossbeam 10, and the cover plate 16 is pivotally connected by the pivot 164 formed on the outer edge of the connecting rib 162 on the top of the main body 160 sliding into the constricted groove 100. This allows the cover plate 16 to be rotated open (exposing the crossbeam 10 and the movable support mechanism 12) or closed (correspondingly covering the crossbeam 10 and the movable support mechanism 12) by rotating the pivot 164 in the constricted groove 100.

[0050] In another optional embodiment of this utility model, such as Figures 1 to 5As shown, the crossbeam 10 is a cylindrical body with an internal cavity. The movable tensioning mechanism 12 is assembled inside the cavity, and the pressing member 120 extends from the corresponding end face of the crossbeam 10. An adjustment hole 104 is provided on the side wall 102 of the crossbeam 10 for an adjustment tool to pass through and operate the adjustment assembly. The cover plate also covers the adjustment hole 104. In this embodiment, by designing the crossbeam 10 as a cylindrical body with a cavity, it is convenient to assemble the main body of the movable tensioning mechanism 12 inside the cavity, while only the pressing member 120 extends from the corresponding end face of the crossbeam 10. This further improves the overall integrity of the curtain mounting bracket 1 and facilitates modular manufacturing and assembly. In specific implementations, the crossbeam 10 can be made of metal tubular profiles, which offers better structural strength and lower manufacturing costs.

[0051] In another optional embodiment of this utility model, such as Figures 6 to 7 As shown, the transfer rack 14 includes:

[0052] A base 140 fixed to the bottom wall of the crossbeam 10 has two L-shaped hooks 141 symmetrically arranged at predetermined intervals on its bottom surface. Each L-shaped hook 141 includes a vertical plate 1410 connected to the bottom surface of the base 140 and a horizontal plate 1412 extending from the bottom edge of the vertical plate 1410. The vertical plate 1410 has a snap-fit ​​hole 1411. The horizontal plates 1412 of the two hooks 141 extend towards each other, and the two hooks 141 together form a hanging groove 143.

[0053] A slider 145 is fixed to the top surface of the upper beam 3 of the curtain. The top of the slider 145 has elastic hooks 146 on opposite sides. The top of the slider 145 slides into the hanging groove 143 from the inlet 1430 at one end of the hanging groove 143 and is supported by the horizontal plates 1412 of the two L-shaped hooks 141 and is correspondingly engaged in the buckle hole 1411 by the elastic hooks 146.

[0054] In this embodiment, a hanging groove 143 is formed on the bottom surface of the base 140 by two L-shaped hooks 141. A slider 145 is fixed on the top surface of the upper beam 3, and the top of the slider 145 slides into the hanging groove 143. The elastic hooks 146 formed on both sides of the top of the slider 145 are engaged with the corresponding buckle holes 1411 formed on the vertical plate 1410 of the L-shaped hooks 141, thus fixing the slider 145 to the base 140. This allows the upper beam 3 of the curtain to be assembled and fixed to the horizontal beam 10. The assembly process is simple and easy to operate. When disassembly is required, simply remove the elastic hooks 146 from the corresponding buckle holes 1411, and pull the upper beam 3 to remove the slider 145 fixed to its top surface from the hanging groove 143.

[0055] In another optional embodiment of this utility model, such as Figure 1 , Figure 6 and Figure 7 As shown, the transfer rack 14 also includes an elastic retainer 147. A baffle 148 is formed on the bottom wall of the base 140 at the end of the hanging groove 143 away from the inlet / outlet 1430. The elastic retainer 147 is placed in the hanging groove 143 and its two ends elastically press against the baffle 147 and the slider 145 respectively, thereby positioning the slider 145 at the position where the elastic hook 146 abuts against the end wall of the buckle hole 1411 away from the baffle 147. In this embodiment, an elastic retainer 147 is added inside the hanging groove 143, and a baffle 148 is formed on the base for one end of the elastic retainer 147 to abut against, while the other end of the elastic retainer 147 abuts against the slider 145. This causes the elastic hook 146 on the slider 145 to abut against the end wall of the latching hole 1411 away from the baffle 148, thereby effectively preventing the slider 145 from sliding within the hanging groove 143. Furthermore, when the upper beam 3 needs to be disassembled, the elastic hook 146 can provide auxiliary thrust when it exits the latching hole 1411, facilitating the slider 145 to slide out of the hanging groove 143. In specific implementations, the elastic retainer 147 can be constructed using elastic elements such as coil springs or elastic rubber blocks. Furthermore, to facilitate the positioning of the elastic retainer 147, a receiving groove 1450 with an opening at one end facing the baffle 148 can be formed on the slider 145. The elastic retainer 147 is inserted into the receiving groove 1450 through the opening, with one end located outside the receiving groove 1450 and abutting against the baffle 148.

[0056] In another optional embodiment of this utility model, such as Figures 8 to 11 As shown, the adjustment component 122 includes:

[0057] A box 1220 assembled at one end of the crossbeam 10;

[0058] A double-ended screw 1222 is assembled inside the housing 1220 and is fixed relative to the housing 1220 in the axial direction. The two opposite ends of the double-ended screw 1222 are respectively provided with a first external thread 1223 and a second external thread 1224 with opposite helical directions, and at least one end is exposed from one side of the housing 1220 as an operating end.

[0059] Two nuts 1225 that are screwed to the first external thread 1223 and the second external thread 1224 at both ends of the double-ended screw 1220 and move synchronously towards or away from each other in the axial direction under the drive of the double-ended screw 1222;

[0060] Two push rods 1226 are symmetrically arranged relative to a plane M that passes through the midpoint of the distance between the two nuts 1225 and is perpendicular to the axis of the double-ended screw 1222. One end of each push rod 1226 serves as a connecting end 1226a, which is connected to the two nuts 1225 in a one-to-one transmission manner and moves synchronously under the drive of the two nuts 1225. The other end of each push rod 1226 serves as a driving end 1226b, which is hinged to the pressing member 120. When the connecting end 1226a moves synchronously with the nuts 1225, the driving end 1226b drives the pressing member 120 to slide accordingly. The adjacent sides of the driving ends 1226b of the two push rods 1226 are also provided with first retaining teeth 1226c that keep them meshing when the two push rods 1226 rotate under the drive of the nuts 1225.

[0061] Two support rods 1228 are symmetrically arranged with respect to the plane of symmetry M. One end of each support rod 1228 serves as a pivot end 1228a, which is pivotally connected to the housing 1220 via a first pivot 130. The other end of the two support rods 1228 serves as a support end 1228b, which is pivotally connected to the two nuts 1225 one-to-one via a second pivot 132. The central axes of the first pivot 130 and the second pivot 132 are both perpendicular to the axial direction of the double-ended screw 1222. The adjacent sides of the pivot ends 1228a of the two support rods 1228 are also provided with second retaining teeth 1228c that keep them meshing with each other when the two support rods 1228 rotate around the first pivot 130.

[0062] This embodiment provides a specific structural configuration of the adjustment component 122, which drives two nuts 1225 to move synchronously towards or away from each other via a double-ended screw, thereby driving two push rods 1226 to move synchronously accordingly. The pressing member 120 connected to the driving end 1226b of the push rod 1226 will slide accordingly and extend and retract relative to the crossbeam 10. Furthermore, two support rods 1228 are further provided, one end of which serves as a support end 1228b and is pivotally connected to the two nuts 1225 one-to-one, so that they can rotate accordingly when the nuts 1225 slide. The first locking teeth 1229 provided at the pivot ends of the two support rods 1228 mesh with each other, which helps to maintain the stability of the internal transmission of the entire movable tensioning mechanism 12 and ensures that the extension and retraction of the pressing member 120 is smooth and stable. In a specific implementation, the box body 1220 can be composed of a main box body 1220a and a box cover 1220b, with an exposed through hole 1220c formed on the side wall of the main box body 1220a; the connecting end 1226a of the push rod 1226 can be directly pivotally connected to the nut 1225, or it can be connected to the nut 1225 through a connecting rod 1227, that is: one end of the connecting rod 1227 is pivotally connected to the nut 1225 (which can be achieved by means of the second pivot 132) and the other end is pivotally connected to the connecting end 1226a of the push rod 1226 through the third pivot 134. Furthermore, multiple guide grooves 1220d are respectively provided on the inner top and bottom walls of the box body 1220. Corresponding guide posts 1226d, 1228d, and 1227d are provided on the top and bottom surfaces of the middle sections of the push rod 1226, support rod 1228, and connecting rod 1227. The guide posts 1226d, 1228d, and 1227d are respectively placed within their respective guide grooves 1220d, and serve to limit and guide the movement of the push rod 1226, support rod 1228, and connecting rod 1227, allowing the movable tensioning mechanism 12 to operate more smoothly. It is understood that movable tensioning mechanisms 12 are already quite common in various no-drill curtain products. This application can also use other existing movable tensioning mechanisms 12 to achieve the function of tightening and fixing the crossbeam 10 to the top of the window frame 4.

[0063] In another optional embodiment of this utility model, such as Figures 9 to 11 As shown, the pressing member 120 includes:

[0064] A pressing seat 1200 is hinged at one end to each of the two push rods 1226. The pressing seat 1200 has a sliding groove 1201 that extends along the sliding direction of the pressing seat 1200 and has an opening at the end away from the push rod 1226. The groove walls on opposite sides of the sliding groove 1201 are also provided with a limiting slot 1203 that extends parallel to the sliding groove 1201 and is elongated. The sliding groove 1201 has a guide hole 1205 on the groove end wall 1201a near the push rod 1226.

[0065] A retractable and slidable pressing block 1206 is assembled within the slide groove 1201 and extends out of the opening of the slide groove 1201 at one end. On opposite sides of the pressing block 1206, limiting hooks 1207 are respectively formed, corresponding to the limiting slots 1203 and limiting the sliding stroke of the pressing block 1206. A guide rod 1208 protrudes from the pressing block 1206 and is correspondingly inserted into the guide hole 1205; and

[0066] The reset elastic element 1209 is disposed in the slide groove 1201 and its two ends respectively abut against the pressing block 1206 and the groove end wall 1201a of the slide groove 1201 away from the opening.

[0067] This embodiment provides a specific structure for the pressing member 120, which is hinged at one end of the pressing seat 1200 to the push rod 1226 of the adjusting component 122, and can slide accordingly under the action of the push rod 1226. This allows the pressing block 1206, which is slidably assembled on the pressing seat 1200, to also slide along with the pressing seat 1200. The reset elastic member 1209 can provide sufficient elastic thrust, so that the pressing block 1206 is tightly pressed against the vertical frame 40 of the window frame 4, achieving stable support and fixation.

[0068] On the other hand, this utility model embodiment also provides a curtain, including a top beam 3, a curtain body 5 connected to the top of the top beam 3, and a curtain mounting bracket 1 as described in any of the above embodiments, wherein the top beam 3 is fixed to the transfer frame 14 of the curtain mounting bracket 1.

[0069] This embodiment uses the curtain mounting bracket 1 described in any of the above embodiments to assemble the curtain into the window frame 4. It allows for a more suitable design of the upper beam 3 length and curtain width 5 based on the inner width of the window frame 4. This effectively ensures that the gaps between the two ends of the upper beam 3 and the two sides of the curtain 5 and the corresponding vertical frame 40 of the window frame 4 are symmetrically distributed and relatively narrow, avoiding uneven light transmission on both sides and excessive light transmission on one side. The curtain provided in this embodiment can be any type of curtain with an upper beam, such as Roman blinds, honeycomb blinds, Venetian blinds, or sun and moon blinds.

A baffle is formed on the bottom wall of the base at the end of the hanging groove away from the entrance / exit. The elastic retainer is placed in the hanging groove and its two opposite ends elastically press against the baffle and the slider respectively, thereby positioning the slider at the position where the elastic hook abuts against the end of the buckle hole away from the baffle.

8. The curtain mounting bracket as described in claim 1, characterized in that, The adjustment component includes: A box assembled at one end of the crossbeam; A double-ended screw is assembled inside the box and fixed axially relative to the box. The two opposite ends of the double-ended screw are respectively provided with a first external thread and a second external thread with opposite helical directions, and at least one end is exposed from one side of the box as an operating end. Two nuts that are screwed into the first and second external threads at both ends of the double-ended screw and move synchronously towards or away from each other in the axial direction under the drive of the double-ended screw; Two push rods are symmetrically arranged with respect to the midpoint of the distance between the two nuts and perpendicular to the axis of the double-ended screw. One end of each push rod serves as a connecting end, corresponding to one of the two nuts, and moves synchronously under the drive of the two nuts. The other end of each push rod serves as a driving end, hinged to the corresponding pressing member. When the connecting end moves synchronously with the nuts, the driving end drives the pressing member to slide accordingly. Adjacent sides of the driving ends of the two push rods are also provided with first locking teeth that maintain mutual engagement when the two push rods rotate under the drive of the nuts; and Two support rods are symmetrically arranged relative to the symmetrical face. One end of each support rod is pivotally connected to the housing via a first pivot, while the other end of the two support rods is pivotally connected to the two nuts via a second pivot. The central axes of the first and second pivots are perpendicular to the axial direction of the double-ended screw. The adjacent sides of the pivot ends of the two support rods are also provided with second locking teeth that keep them meshing with each other when the two support rods rotate around the first pivot.
