Detailed Description

Exemplary embodiments that embody features and advantages of the present invention will be described in detail in the following description. It is to be understood that the invention is capable of other and different embodiments and its several details are capable of modification without departing from the scope of the invention, and that the description and drawings are to be regarded as illustrative in nature and not as restrictive.

To the deficiency of the prior art, this embodiment provides a novel articulated curtain ring, and this curtain ring is convenient for people to carry out the loading and unloading of curtain ring at the eminence.

Referring to fig. 1 to 4 together, the curtain ring 100 includes an outer ring 1 and an inner support ring 2, which are separable. The outer ring 1 comprises two parts, namely a first open ring 11 and a second open ring 13 which are arc-shaped respectively; the opposite ends of the first and second

open rings

11 and 13 are hinged to each other so that the outer ring 1 can be formed into a ring structure that can be opened and closed, so that a rod 200 such as a curtain rod can be inserted into the outer ring 1, and the opposite ends can be connected to close the outer ring 1. The inner support ring 2 can be arranged in the outer ring 1 and elastically props against the outer ring 1, and finally an integral annular structure sleeved on the rod body 200 is formed. It should be noted that the directions of "inside and outside" appearing hereinafter are all based on the view direction of fig. 1.

Referring to fig. 5, the first open loop 11 has an arc structure with an opening 101. The size of the opening 101 is not smaller than the diameter of the curtain rod. The curtain rod can enter the inside of the first open loop 11 through the opening 101. The first open loop 11 is approximately C-shaped, and the central angle of the first open loop 11 is larger than 180 degrees, so that the first open loop 11 can be stably hung on the rod 200 and cannot easily fall off the rod 200.

Referring to fig. 6 to 11, the first open ring 11 has a first hinge portion 110 and a first combining portion 120 at two circumferential ends thereof, the first hinge portion 110 is hinged to the second hinge portion 130 of the second open ring 13, and the first combining portion 120 is snap-fitted to the second combining portion 140 of the second open ring 13.

The first hinge part 110 is a circumferential guide groove a111 and a transverse groove 113 which are concavely arranged on the outer circumferential wall of the first open ring 11, and the circumferential guide groove a111 and the transverse groove 113 are vertically communicated to form a T-shaped groove. The structural design of the T-shaped groove can limit the second hinge part 130 embedded therein from moving left and right, and the connection stability is increased. Specifically, the circumferential guide groove a111 extends in the circumferential direction of the first open ring 11, and both sides of the circumferential guide groove a111 have a space from both sides in the width direction of the first open ring 11. And the lateral groove 113 extends in the width direction of the first open loop 11 and communicates with both sides in the width direction of the first open loop 11. The cross section of the transverse groove 113 is arc-shaped for the second hinge portion 130 to be rotatably disposed therein. Preferably, the depth of the lateral groove 113 is greater than the depth of the circumferential guide groove a 111.

The first engaging portion 120 is a circumferential guide groove b121 and a catching groove 123 recessed in the outer circumferential wall of the first open ring 11. The circumferential guide groove b121 extends in the circumferential direction of the first open ring 11, and the catching groove 123 extends in the width direction of the first open ring 11 and communicates with both sides in the width direction of the first open ring 11. The cross section of the slot 123 is rectangular. The locking groove 123 is vertically communicated with the circumferential guide groove b121 to form a T-shaped groove.

Referring to fig. 6 to 13, the second open loop 13 is a circular arc structure. The size of the second open loop 13 is matched with the size of the opening 101 of the first open loop 11, and the second open loop 13 can correspondingly fill the opening 101 to splice to form a closed outer loop 1.

The second open loop 13 has a second hinge portion 130 and a second joint portion 140 at both ends in the circumferential direction. The second hinge portion 130 is butt-hinged to the first hinge portion 110, and therefore, the second open loop 13 can rotate around the hinge point of the first hinge portion 110 and the second hinge portion 130, so that the first combining portion 120 and the second combining portion 140 are relatively opened and closed. The gap formed when the first combining portion 120 and the second combining portion 140 are opened can allow the rod body 200 to pass through, and the complete circular outer ring 1 can be sleeved on the rod body 200 when the first combining portion 120 and the second combining portion 140 are clamped and closed.

The second hinge portion 130 includes a neck portion a131 circumferentially extending from an end portion of the second open loop 13 and a pillar portion a133 oppositely protruding from both sides of a front end of the neck portion a 131. The two sides of the neck portion a131 and the two sides of the second open loop 13 in the width direction have a space therebetween. Preferably, the width of the neck portion a131 gradually decreases inward in the radial direction, that is, the neck portion a131 has an inverted trapezoidal shape in the radial direction. The width direction of the second open loop 13 is perpendicular to the direction (thickness direction) of the line connecting the inner peripheral wall and the outer peripheral wall of the second open loop 13. The neck portion a131 can be fitted into the circumferential guide groove a111, and the left and right positions of the first open ring 11 and the second open ring 13 are ensured to be matched. The columnar portion a133 has a circular cross section. The end portions of the two columnar portions a133 which are relatively distant are flush with both side end portions in the width direction of the second open ring 13, respectively. Since the lateral groove 113 has a shape that matches the arc-shaped profile of the columnar portions a133, the two columnar portions a133 are rotatably provided in the lateral groove 113 so that the second open ring 13 can rotate relative to the first open ring 11. The diameter of the pillar portion a133 is slightly larger than the opening of the lateral groove 113, and the pillar portion a133 can be pressed into the lateral groove 113 by the elastic deformation of the sidewall of the lateral groove 113, thereby preventing the pillar portion a133 from being separated from the lateral groove 113 when rotating. When the second open ring 13 is rotated outward, the neck portion a131 may be disengaged from the circumferential guide groove a 111; as the neck portion a131 is rotated inward, it gradually comes closer until it is re-fitted in the circumferential guide groove a 111.

The second combining portion 140 is snap-fit with the first combining portion 120. The second coupling portion 140 includes a neck portion b141 circumferentially extending from an end portion of the second open loop 13 and column portions b143 protruding from both sides of a front end of the neck portion b 141. The neck portion b141 is fitted in the circumferential guide groove b 121. The cross section of the columnar portion b143 is rectangular, and the two columnar portions b143 are clamped in the clamping groove 123. The cross section of the columnar portion b143 may be other polygonal shapes such as a triangle or a hexagon. In the present embodiment, the above-mentioned snap-fit structure can better limit the relative displacement of the first open ring 11 and the second open ring 13 in the left-right direction, and ensure the stable shape and the integrity of the whole ring structure. In other embodiments, the second coupling portion 140 and the first coupling portion 120 may be hinged together. When in hinged engagement, the second joint 140 and the first joint 120 are similar in structure to the first hinge 110 and the second hinge 130, respectively.

Referring back to fig. 1, the inner support ring 2 is a hollow ring structure, and is made of an elastic material. The inner support ring 2 has a notch 201, and two ends of the inner support ring 2 located at the notch 201 can be elastically separated relatively, so that the notch 201 can be enlarged to be larger than the size of the curtain rod for the curtain rod to pass through. After the first open ring 11 and the second open ring 13 form the closed outer ring 1 through clamping, the circumference of the outer ring 1 is fixed. The inner support ring 2 is arranged around the inner peripheral wall of the outer ring 1, and a closed inner ring is formed by clamping a notch 201 of the inner support ring and a limiting protrusion 103 on the outer ring 1. The closed inner ring elastically abuts against the closed outer ring 1 to form a curtain ring 100 which is stable in the radial direction and the circumferential direction.

The inner support ring 2 is a ring structure made of an elastic material, i.e., the inner support ring 2 has elasticity. When the inner support ring 2 is embedded in the annular groove, the inner support ring 2 can bear radial force and cannot be compressed by inward stress due to the fact that the inner support ring can expand in the annular groove under the elastic action of the inner support ring; meanwhile, the outward expansion function of the inner ring and the inextensibility of the outer ring 1 are restricted from each other, so that the inner support ring 2 and the outer ring 1 can be closely fitted together. Moreover, the inner support ring 2 in the expanded state can outwardly abut against and support the outer ring 1, so that the outer ring 1 maintains a stable ring structure. Thus, the curtain ring 100 formed by combining the inner support ring 2 and the outer ring 1 can be firmly sleeved on the curtain rod, and even if the curtain ring 100 and the curtain connected with the curtain ring 100 are forcibly pulled downwards by people, the curtain ring 100 can still keep the whole integrity and cannot be pulled to be broken and scattered. Because the internal perisporium of inner support ring 2 and the body of rod 200 direct contact of curtain pole, this internal perisporium can have smooth circular arc transition surface, and inner support ring 2 can select for use and have lubricated function's nylon materials in order to further play lubricated noise cancelling effect to minimize the frictional force that produces in the relative slip in-process of inner support ring 2 and the body of rod 200. Therefore, people can use less strength to easily pull the curtain ring 100 sleeved on the curtain rod back and forth to close the curtain.

In the process of installing the curtain ring 100, firstly, a person can stand on the ground to correspondingly connect the first hinge part 110 of the first open ring 11 and the second hinge part 130 of the second open ring 13 to form an openable outer ring 1; the second ring 13 is turned outwards with respect to the first ring 11, so that the outer ring 1 is opened to form a gap for the rod 200 to pass through. Then, the high-place operation is carried out, people can lift the opened outer ring 1 by one hand and hang the outer ring 1 on the rod body 200 through the gap; then, the separated first combining portion 120 and the second combining portion 140 can be grasped by one hand and correspondingly clamped, and the outer ring 1 is closed to be fixedly sleeved on the rod body 200. Finally, the mounting work of the inner support ring 2 is prepared. Firstly, the notch 201 of the inner support ring 2 is enlarged until the inner support ring 2 can be sleeved on the curtain rod through the notch 201; the inner support ring 2 is embedded in the outer ring 1, and the notch 201 is aligned with the limit protrusion 103 on the clamping first open ring 11, at this time, the inner support ring 2 elastically supports against the outer ring 1, and the two are combined to form a firm and stable curtain ring 100. In the process of installing the outer ring 1, the first open ring 11 and the second open ring 13 are not easy to separate and fall off, so that smashing injury is avoided. Moreover, as partial connection operation of the curtain ring 100 can be performed on the ground in advance, the operation can be performed by one hand during high-altitude operation, the operation difficulty is reduced, and the safety is higher.

In the process of detaching the curtain ring 100, the inner support ring 2 is firstly separated from the inner part of the outer ring 1, and the notch 201 of the inner support ring 2 is torn off again, so that the inner support ring 2 is taken down from the curtain rod through the notch 201. Then, by separating the first coupling part 120 and the second coupling part 140, the opened outer ring 1 can be directly removed from the curtain rod through the gap without detaching the hinge part at the other end, thereby improving the detaching efficiency. Meanwhile, the first open ring 11 and the second open ring 13 cannot be separated and fall off, and the whole disassembly process is simple and quick.

Referring to fig. 14, in an embodiment, the inner circumferential wall of the first open ring 11 is provided with a first groove. The inner peripheral wall of the second open loop 13 is provided with a second groove, and the second groove and the first groove can be communicated to form an annular groove 401. The size of the inner support ring 2 is matched with the size of the annular groove 401 so as to be correspondingly embedded in the annular groove 401. In addition, the notch 201 of the inner support ring 2 is opposite to the limiting protrusion 103 on the first open ring 11, and two ends of the notch 201 are respectively clamped on two sides of the limiting protrusion 103 correspondingly, so as to perform a limiting function. Thus, the inner support ring 2 and the outer ring 1 are firmly combined in the radial direction and the circumferential direction, and meanwhile, the inner support ring 2 and the outer ring 1 cannot slide in the left-right direction.

Referring to fig. 15, in another embodiment, the outer peripheral wall of the inner support ring 2 is recessed with a ring-shaped groove 401. The inner peripheral wall of the first open ring 11 is provided with a first arc-shaped protrusion in a protruding manner, the inner peripheral wall of the second open ring 13 is provided with a second arc-shaped protrusion in a protruding manner, and the second protrusion and the first protrusion can be spliced to form a complete annular protrusion 403 and are embedded in the annular groove 401 together.

The first open ring 11 and the second open ring 13 are each an integrally formed structure made of a plastic or metal material. The purpose of this is that the first open loop 11 and the second open loop 13 are both strong and rigid enough not to shrink, so that the circumference of the outer ring 1 formed by the first open loop 11 and the second open loop 13 is a fixed value. The enough strength of the curtain ring cannot be easily deformed, so that the outer ring 1 can be ensured to have corresponding bearing performance, the outer ring 1 can be ensured to be still kept complete when being subjected to outward pulling force, and especially can resist deformation when being pulled by people forcefully, so that the normal use of the curtain ring 100 is ensured, and the service life of the curtain ring 100 is prolonged.

Referring to fig. 16 and 17 in conjunction with fig. 1. The curtain ring 100 further includes a hanger 3 for hanging a curtain. The hanger 3 is provided on the outer peripheral wall of the first open ring 11.

With the help of the hanging parts 3, the curtain ring 100 can also be applied to places where rod pieces are already installed, such as a clothes hook in a wardrobe, a bath cloth hook in a bathroom and the like, and has wide application range.

The hanger 3 is an annular structure with a shape similar to the outer ring 1 and a slightly smaller size. The hanger 3 includes a large ring 31 integrally formed on the outer peripheral wall of the first open ring 11, a small ring 33 correspondingly connected to the large ring 31, and an inner ring 35. The large ring 31 has an opening for the small ring 33 to be inserted into the large ring 31. Wherein the specific structure of the large ring 31 can be similar to the first open ring 11, the structure of the small ring 33 can be similar to the second open ring 13, and the structure of the inner ring 35 can be similar to the inner support ring 2. The large ring 31 and the small ring 33 are spliced to form a complete annular structure in a connecting mode of clamping or hinging and the like; the inner ring 35 is disposed around the ring structure to form a solid integral structure. Thus, the hanger 3 and the outer ring 1 are integrated into a double ring, and a wider application range is possible.

To sum up, the utility model provides a curtain ring 100 has following advantage and positive effect at least:

the curtain ring 100 includes an outer ring 1 and an inner support ring 2 wound around the inner circumferential wall of the outer ring 1. Wherein the outer ring 1 comprises a first open ring 11 and a second open ring 13 which are hinged, the first open ring 11 forms a hinged fit with a second hinge 130 of the second open ring 13 through a first hinge 110, so that the second open ring 13 can rotate around the hinge point, and the first combining part 120 and the second combining part 140 can be opened and closed relatively. In the rotating process, a gap formed when the first combining part 120 and the second combining part 140 are relatively separated can be penetrated by the rod body 200; then, the second ring 13 rotates in the opposite direction, the opening 101 is matched with the second ring 13 by compressing the first ring 11, the first combining portion 120 and the second combining portion 140 are closed, and finally, the complete ring-shaped outer ring 1 is fixed on the rod body 200. The inner support ring 2 is clamped with the limiting protrusion 103 of the inner circumferential wall of the outer ring 1 through the notch 201 to ensure that the connection of the first open ring 11 and the second open ring 13 is stable enough and cannot be separated.
