Description

Technical Field

[0001] The present invention relates to a curtain structure, and more particularly to a hanging weight structure of a curtain. Background Art

[0002] Generally, windows are provided in an indoor space for ventilation and lighting, and generally curtains are also installed on the windows for purposes such as blocking sunlight, increasing privacy or beautifying the environment. Generally, curtains are made of fabric or sheet material. Since the material is soft, a hanging weight is usually installed at the bottom edge thereof, and the weight of the hanging weight keeps the curtain in a flat and hanging state. However, when the hanging weight is used for a general vertical curtain or a sheet curtain that is stretched left and right, the lower ends of the curtain sheets are not connected to each other and are in a state of swinging arbitrarily, resulting in an uneven or knotted appearance of the lower ends of such curtains, which really needs to be improved.

[0003] In view of this, based on years of experience in the manufacturing, development and design of related products, the inventor of the present invention has carefully designed and evaluated in detail for the above-mentioned objectives, and finally obtained the present invention which is truly practical. Summary of the Invention

[0005] The hanging weight structure of the above-mentioned curtain includes a hanging weight member, a connecting member, and two cover bodies. In the upper half of the hanging weight member, a combination groove is provided downward from the top. The combination groove is used for installing a curtain piece. In the lower half of the hanging weight member, a hollow channel is transversely provided through the structure. And on one side surface of the lower half of the hanging weight member, a short groove is provided only at one end. The short groove communicates with the hollow channel. And on the other side surface of the lower half of the hanging weight member, a long groove is provided through both ends. The long groove also communicates with the hollow channel. The connecting member has a long plate body with a first end and a second end. On one side surface of the long plate body, a first shaft portion is provided at the first end. On the other side surface of the long plate body, a second shaft portion is provided at the second end. At the end of the first shaft portion, a first wheel portion is formed. At the end of the second shaft portion, a second wheel portion is formed. The areas of the first and second wheel portions are both larger than those of the first shaft portion and the second shaft portion. And a first annular groove and a second annular groove are respectively formed between the first and second wheel portions and the two side surfaces of the long plate body. In the first and second annular grooves, a limiting post is respectively provided along the forming direction of the long plate body by the first and second shaft portions. The connecting member is slidably arranged in the short groove of one hanging weight member with the first shaft portion. The first wheel portion of the first shaft portion is placed in the hollow channel for limiting and positioning. And the second shaft portion is slidably arranged in the long groove of the other hanging weight member. And the second wheel portion of the second shaft portion is placed in the hollow channel of the other hanging weight member for limiting and positioning. The two cover bodies are respectively sleeved on the two end portions of the hanging weight member. And the connecting member is blocked by the two cover bodies. One of the cover bodies is provided with a limiting rod facing the hanging weight member from the end edge. And the cover body with the limiting rod is assembled on the end of the hanging weight member where no short groove is provided. And the limiting rod is slidably arranged in the long groove. Thus, several hanging weight members can be sequentially connected in series through the connecting member. By using the design of the long groove for the sliding displacement of the second shaft portion of the connecting member, the hanging weight member can be pushed out and unfolded or retracted and concentrated. To achieve the connection of several hanging weight members and prevent the situation of the lower pendulum of the curtain piece being messy and knotted.

[0006] Preferably, two convex ribs are symmetrically provided at the top ends of the two inner walls of the combination groove of the hanging weight member. A pressure strip is provided at the lower end portion of each curtain piece. The pressure strip is slidably assembled into the combination groove of the hanging weight member. And the pressure strip is blocked by the two convex ribs to prevent it from detaching and form positioning.

[0007] The efficacy compared with the prior art: The hanging weight member is respectively provided with a short groove and a long groove on the two side surfaces. And between two hanging weight members, they are respectively connected and combined by a connecting member. So that when the hanging weight members are installed at the lower end portion of the curtain piece, they can be interconnected through the connecting member at the same time. To ensure the stability of the lower pendulum of several curtain pieces. And improve the flatness when the curtain pieces are collected or unfolded. It helps to improve the light-shielding and light-adjusting effects of the curtain pieces and has an improvement in practicality. Description of the Drawings

[0042] To enable your review committee to have a further understanding and recognition of the purpose, features and effects of the present invention, the following is a detailed description in conjunction with the accompanying drawings:

[0043] First of all, please refer to Figure 1 , 2As shown in FIGS. 3, a weight structure of a curtain includes a weight member 10, a connecting member 20 and two cover bodies 30. A combined groove 11 is provided downward from the top end on the upper half of the weight member 10 for installing a curtain piece 40. A hollow channel 12 is transversely formed through the structure on the lower half of the weight member 10. Only one end of one side of the lower half of the weight member 10 is provided with a short groove 13, and the short groove 13 communicates with the hollow channel 12. A long groove 14 is formed through both ends on the other side of the lower half of the weight member 10, and the long groove 14 also communicates with the hollow channel 12. The connecting member 20 has a long plate body 21 with a first end 211 and a second end 212. A first shaft portion 22 is protruded from one side surface of the long plate body 21 at the first end 211, and a second shaft portion 23 is protruded from the other side surface of the long plate body 21 at the second end 212. A first wheel portion 221 is formed at the end of the first shaft portion 22, and a second wheel portion 231 is formed at the end of the second shaft portion 23. The areas of the first and second wheel portions 221 and 231 are larger than those of the first shaft portion 22 and the second shaft portion 23, and a first annular groove 222 and a second annular groove 232 are respectively formed between the first and second wheel portions 221 and 231 and the two side surfaces of the long plate body 21. A limiting post 223 and a limiting post 233 are respectively arranged along the forming direction of the long plate body 21 in the first and second annular grooves 222 and 232 by the first and second shaft portions 22 and 23. The two cover bodies 30 are respectively sleeved on the two end portions of the weight member 10, and the connecting member 20 is blocked by the two cover bodies 30. A limiting rod 31 is provided from the edge of one cover body 30 towards the weight member 10.

[0044] For the composition of its structure, please refer to Figure 2 、 3As shown in FIGS. 4, 5, and 6, the curtain unit is a single-piece curtain structure, having an upper rail 50 and several sliding seats 51 that slide along the upper rail 50 to actuate synchronously for unfolding and retracting. The sliding seats 51 are connected to the upper ends of several curtain sheets 40, and a weight member 10 is respectively installed at the lower ends of the several curtain sheets 40. The weight members 10 are arranged with the short grooves 13 facing the long grooves 14 and are sequentially assembled at the lower ends of the curtain sheets 40, and are combined and installed with the curtain sheets 40 through the combination grooves 11. Further, two convex ribs 111 are symmetrically provided at the tops of the two inner walls of the combination groove 11. A pressure strip 41 is provided at the lower end of each curtain sheet 40. The pressure strip 41 is slidably assembled into the combination groove 11 of the weight member 10, and is blocked by the two convex ribs 111 to prevent the pressure strip 41 from detaching to form a positioning. The connecting member 20 has its first shaft portion 22 slidably disposed in a short groove 13 of a weight member 10. The first wheel portion 221 of the first shaft portion 22 is placed into the hollow channel 12 for limiting and positioning. At the same time, the second shaft portion 23 is slidably disposed in the long groove 14 of another weight member 10, and the second wheel portion 231 of the second shaft portion 23 is placed into the hollow channel 12 of another weight member 10. Thus, a connecting member 20 is sequentially connected between the two weight members 10. Further, a cover 30 is respectively assembled at both ends of the weight member 10, and the cover 30 having the limiting rod 31 is assembled at one end of the weight member 10 that does not have the short groove 13, and the limiting rod 31 is slidably disposed in the long groove 14. Furthermore, the curtain sheet 40 and the connecting member 20 are blocked and restricted by the cover 30, and the design of the long groove 14 is used to allow the second shaft portion 23 of the connecting member 20 to slide and displace, so as to connect several weight members 10, achieving the purpose of synchronously pushing out, unfolding or retracting and concentrating the weight members 10, and further preventing the situation that the lower pendulum of the curtain sheet 40 is messy and knotted.

[0045] For the actual usage state of its structure, please continue to refer to Figure 1 、 4As shown in FIGS. 7 and 8, when the curtain sheet 40 of the curtain unit is restricted by the sliding seat 51 and collected on one side of the upper rail 50, the plumb weights 10 at the lower end of the curtain sheet 40 are aligned side by side, and each connecting member 20 is located at one end of the plumb weight 10, and the first end 211 of the long plate body 21 faces the cover body 30 at this end. When the user pulls the sliding seat 51 outwards along the upper rail 50 and unfolds the curtain sheet 40 in sequence, the plumb weight 10 will be pulled out synchronously under the traction of the curtain sheet 40. At this time, the connecting member 20 of the plumb weight 10 located in the short groove 13 will slide and displace along the long groove 14 of the other plumb weight 10 with the second shaft portion 23, and then displace the connecting member 20 to the other end of the other plumb weight 10. When the other curtain sheets 40 are continuously pulled out by the sliding seat 51 and unfolded, the other plumb weights 10 will also be pulled out under the traction of the other curtain sheets 40, achieving the purpose of sequentially pulling out several plumb weights 10 as the curtain sheet 40 unfolds. When the curtain sheet 40 of the curtain unit unfolds to block light, the lower hems of the curtain sheets 40 can also be connected to each other through the plumb weights 10, preventing the lower hems of the curtain sheets from being blown by the wind and getting messy and knotted, and ensuring the flatness of the unfolded curtain sheet 40 during use.

[0046] In addition, when the plumb rod 10 displaces along the long groove 14 of the other plumb rod 10 with the connecting member 20, the other plumb rod 10 further uses the limiting rod 31 of the other cover body 30 to provide abutting restriction for the connecting member 20 when the plumb rod 10 slides and displaces, thereby restricting the pulling distance of each plumb rod 10. At the same time, the overlapping area of each curtain sheet 30 when unfolded is increased by the length of the limiting rod 31, thereby improving the light shielding effect of the curtain.

[0047] On the contrary, when the curtain sheets 40 are folded and concentrated, the connecting member 20 of the plumb weight 10 located in the short groove 13 will displace and retract in the reverse direction along the long groove 14 of the other plumb weight 10 with the second shaft portion 23. When the other curtain sheets 40 are retracted in conjunction, the other plumb weights 10 will also be pulled back and concentrated under the traction of the other curtain sheets 40, so as to achieve the purpose of several plumb weights 10 being retracted and concentrated as the curtain sheets 40 are retracted.

[0048] Furthermore, please refer to Figure 8 、 9As shown, the connecting member 20 can also swing and act in the short slots 13 and long slots 14 with the first and second shaft portions 22 and 23, so that the weight member 10 can swing and lift with the first shaft portion 22 or the second shaft portion 23 as the axis and the long plate body 21 as the arm. When the lengths of the curtain pieces 40 are different and have errors, the height of the weight member 10 can be finely adjusted by using the connecting member 20, and the weight member can be firmly assembled and installed at the lower end of the curtain piece 40, improving the practicality of the installation of the weight member 10. Moreover, the limiting posts 223 and 233 of the first and second shaft portions 22 and 23 will abut against the upper and lower end faces of the short slot 13 and long slot 14 when the connecting member 20 swings, thereby restricting the swinging angle of the long plate body 21 and preventing the weight member 10 from forming a height difference due to excessive swinging of the connecting member 20 during normal use, which will affect the flatness of the curtain piece 40 and make it have stability in use.

[0049] For the structure of the above specific embodiment, the following benefits can be obtained: The weight member 10 is respectively provided with a short slot 13 and a long slot 14 on both side surfaces, and a connecting member 20 is connected between the two weight members 10. When the weight member 10 is installed at the lower end of the curtain piece 40, the weight members 10 can be interconnected through the connecting member 20 to ensure the stability of the lower pendulum of several curtain pieces 40 and improve the flatness when the curtain pieces 40 are collected or unfolded. Moreover, one of the cover bodies 30 is provided with a limiting rod 31 for the connecting member 20 to abut against and be restricted, which helps to improve the light shielding and light adjusting effects of the curtain pieces and enhance the practicality.

[0050] The above is only a preferred embodiment of the present invention, and the scope of implementation of the present invention cannot be limited thereby; that is, all equal changes and modifications made according to the scope of the patent application of the present invention should still fall within the scope covered by the patent of the present invention.
