[0067] While this invention has been illustrated and described with reference to specific embodiments, it should not be limited to the details shown. Rather, various modifications to these details may be made within the scope of equivalents of the claims and without departing from the invention.

[0068] The descriptions of directions such as "front," "back," "up," and "down" used in this article are for ease of understanding only. This invention is not limited to these directions, but can be adjusted according to actual circumstances.

[0069] First refer to Figures 1 to 7 The general description of the carrier 200 (e.g., a crib) and the canopy applied to the carrier 200 according to this application. As shown, the carrier 200 has a frame 210, the bottom and sides of which are covered with a drape 230. Figures 13 to 15to carry an infant. In the present embodiment, the frame 210 is in a form that can be collapsed or folded, however in other embodiments, the frame 210 can also be in a fixed form. In the present embodiment, the frame 210 is in a hexagonal shape, however in other embodiments, the frame 210 can have different shapes, such as a rectangular or circular shape.

[0070] At the upper portion of the frame 210, there are provided insertion portions 220. The insertion portions 220 can be in the form of a crease that is bent along the upper edge of the frame 210, or can be in the form of an arc, a straight line, or other shapes. In the present embodiment, the insertion portions 220 are provided at each corner of the frame 210, i.e. there are 6 insertion portions 220 evenly distributed along the upper edge of the frame 210, however in other embodiments, the insertion portions 220 can be provided in a greater or smaller number, such as 2, 4, 8 insertion portions 220.

[0071] The canopy engagement device 100 is detachably inserted on the carrier 200, more specifically, on the insertion portions 220 of the carrier 200. The canopy engagement device 100 can be inserted on any of the insertion portions 220. In the present embodiment, two canopy engagement devices 100 are symmetrically inserted on two opposite insertion portions 220.

[0072] The first canopy rod 300 and the second canopy rod 400 are respectively rotatably connected to the canopy engagement device 100, with the rotation axis X being substantially a straight line connecting the two canopy engagement devices 100. The tarpaulin 500 Figures 13 to 15 is respectively connected to the first canopy rod 300 and the second canopy rod 400. Through the canopy engagement device 100 of the present application, the first canopy rod 300 and the second canopy rod 400 are respectively rotated independently. When the first canopy rod 300 and the second canopy rod 400 are respectively rotated to the two sides so that the carrier 200 is close to a horizontal position, Figure 6 the tarpaulin 500 is fully unfolded, forming a complete sunshade. When one of the first canopy rod 300 and the second canopy rod 400 is rotated to be close to the upper portion of the carrier 200, and the other is rotated to be at an angle with the upper portion of the carrier 200, Figures 1 to 5 , Figure 7 the tarpaulin 500 is partially unfolded, forming a partial sunshade. When the first canopy rod 300 and the second canopy rod 400 are rotated to overlap with each other and close to a horizontal position (not shown), the tarpaulin 500 is completely folded, so that the sunshade is completely collapsed.

[0073] Reference will now be made to Figures 8 to 12 The canopy engagement device 100 according to the present application will be described in detail. As shown in the drawings, the canopy engagement device 100 comprises a socket 110, a first rotating seat 120, a second rotating seat 130, and a locking member 140. The canopy engagement device 100 can further comprise a resilient member 150.

[0074] The socket 110 is used to connect the ceiling engaging device 100 to the carrier 200. The socket 110 has a base end 112 and an engaging end 111. The base end 112 is used to be rotatably connected to the first and second rotating seats 120 and 130, and the engaging end 111 is engaged to the carrier 200. The engaging end 111 has a shape corresponding to that of the insertion portion 220 on the carrier 200. More specifically, the engaging end 111 can have a shape of a caliper that is sleeved outside the insertion portion 220, and a clamping portion 115 can be provided at a lower end of the engaging end 111 to protrude inwardly. When the engaging end 111 is sleeved on the insertion portion 220, the clamping portion 115 is clamped to a lower edge of the insertion portion 220, so as to fix the ceiling engaging device 100 to the carrier 200. The base end 112 has a disc shape, and a center of the disc shape defines a rotating axis X. In the present embodiment, the rotating axis X is substantially perpendicular to a connecting line of the engaging end 111 and the base end 112. That is, the connecting line of the engaging end 111 and the base end 112 extends substantially vertically, and the rotating axis X extends substantially horizontally.

[0075] One side of the base end 112 faces an interior of the carrier 200, hereinafter referred to as an inner side, and the other side of the base end 112 faces an exterior of the carrier 200, hereinafter referred to as an outer side.

[0076] The inner side of the base end 112 is provided with a first positioning recess 113 in the form of a sector recess centered on the rotating axis X. The first positioning recess 113 is arranged in a plurality along a circumferential direction. The first positioning recess 113 is used to accommodate and clamp the first positioning protrusion 123 on the first rotating seat 120 (as shown in Figure 10 、 Figure 11 best shown) so as to fix a relative angle between the first rotating seat 120 and the base end 112. In other embodiments, the base end 112 can be provided with the first positioning protrusion 123 instead of the first positioning recess 113, and correspondingly, the first rotating seat 120 is provided with the first positioning recess 113 instead of the first positioning protrusion 123.

[0077] A first rotation limiting portion 114 is arranged at a circumferential position of the socket 110. In the present embodiment, the first rotation limiting portion 114 is arranged in the form of a sheet extending from a circumferential edge of the socket 110 in an axial direction towards the inner side. In other embodiments, the first rotation limiting portion 114 can be arranged in the form of a rod or other appropriate shape. The first rotation limiting portion 114 is used to limit a range of relative rotation angle between the socket 110 and the first rotating seat 120, which will be described in detail below.

[0078] The first rotating seat 120, the second rotating seat 130, and the locking member 140 are stacked and connected to the base end 112 of the socket 110, and can rotate relative to the socket 110 about the same rotation axis X. Among them, the first rotating seat 120 is stacked between the base end 112 and the second rotating seat 130, and the first ceiling rod 300 and the second ceiling rod 400 are respectively inserted into the first rotating seat 120 and the second rotating seat 130 along a direction perpendicular to the rotation axis X. More specifically, in the direction of the rotation axis X, from the outside to the inside, they are the socket 110, the first rotating seat 120, the locking member 140, and the second rotating seat 130 in sequence. The rotating shaft 160 penetrates the centers of the above-mentioned components in sequence, so as to rotatably assemble them together.

[0079] The first rotating seat 120 has a first disc-shaped portion 121 and a first ceiling rod engaging portion 122. The center of the first disc-shaped portion 121 is located at the rotation axis X, and the first ceiling rod engaging portion 122 extends outward from the outer periphery of the first disc-shaped portion 121 along a direction perpendicular to the rotation axis X. One end of the first ceiling rod 300 is inserted into the first ceiling rod engaging portion 122, so that the rotation of the first disc-shaped portion 121 about the rotation axis X drives the first ceiling rod 300 to rotate about the rotation axis X. On the side (i.e., the outside) of the first disc-shaped portion 121 facing the socket 110, a first positioning protrusion 123 is provided which rises towards the socket 110. The shape and position of the first positioning protrusion 123 correspond to the position of the first positioning recess 113, which is a sector centered on the rotation axis X in this embodiment. In this embodiment, a pair of first positioning protrusions 123 symmetrical along the rotation axis X are provided, but in other embodiments, only one first positioning protrusion 123 can be provided, or more first positioning protrusions 123 can be provided. As described above, the first positioning protrusion 123 on the first rotating seat 120 and the first positioning recess 113 on the socket 110 can be exchanged with each other.

[0080] A first locking portion 124 is provided at a corresponding circumferential position of the first rotating seat 120, and the first rotation limiting portion 114 interacts with the first locking portion 124. In one embodiment, the first locking portion 124 is provided along the circumference of the first rotating seat 120, so that the first rotating seat 120 is limited to rotate relative to the socket 110 between a first angular position and a second angular position. When viewed from the side of the socket 110, if the engaging end 111 of the socket 110 is located at the 6 o'clock position of a clock face, the first angular position is approximately the 3 o'clock position, and the second angular position is approximately the 11 o'clock position.

[0081] The locking member 140 is inserted between the first rotating seat 120 and the second rotating seat 130, and can rotate with the first rotating seat 120 to limit the relative angle between the first rotating seat 120 and the second rotating seat 130 within a certain range. In the present embodiment, the locking member 140 is disposed in the hollow cylindrical space of the first rotating seat 120.

[0082] In the present embodiment, the inner wall of the first rotating seat 120 is provided with an outwardly protruding insertion block 125, and the outer wall of the locking member 140 is provided with an inwardly recessed insertion slot 143. Through the engagement between the insertion slot 143 and the insertion block 125, the locking member 140 is inserted into the first rotating seat 120 in a manner that does not rotate relative to the first rotating seat 120. In other embodiments, the insertion block 125 of the first rotating seat 120 and the insertion slot 143 of the locking member 140 can be interchanged, i.e., the inner wall of the first rotating seat 120 is provided with an inwardly recessed insertion slot 143, and the outer wall of the locking member 140 is provided with an outwardly protruding insertion block 125. The locking member 140 is slidably inserted into the first rotating seat 120, so that the first rotating seat 120 and the sliding block abut against the socket 110 and the second rotating seat 130, respectively.

[0083] In the present embodiment, the locking member 140 is disc-shaped, and is provided with a second positioning protrusion 142 on the side facing the second rotating seat 130 (as best shown in Figure 10 、 Figure 11 ), for insertion into the second positioning recess 133 of the second rotating seat 130, so as to fix the relative angle between the locking member 140 and the second rotating seat 130. In other embodiments, the locking member 140 can be provided with a second positioning recess 133 instead of a second positioning protrusion 142, and correspondingly, the second rotating seat 130 is provided with a second positioning protrusion 142 instead of a second positioning recess 133. The shape of the second positioning protrusion 142 is similar to that of the first positioning protrusion 123, which will not be described again here.

[0084] The second rotating seat 130 has a second disc-shaped portion 131 and a second ceiling rod engaging portion 132. The center of the second disc-shaped portion 131 is located at the rotation axis X, and the second ceiling rod engaging portion 132 extends outwardly from the outer periphery of the second disc-shaped portion 131 in a direction perpendicular to the rotation axis X. One end of the second ceiling rod 400 is inserted into the second ceiling rod engaging portion 132, so that the rotation of the second disc-shaped portion 131 around the rotation axis X drives the second ceiling rod 400 to rotate around the rotation axis X. A second positioning recess 133 is provided on the side (i.e., the inner side) of the second disc-shaped portion 131 facing the locking member 140. The shape and position of the second positioning recess 133 correspond to the second positioning protrusion 142. The shape of the second positioning recess 133 is similar to that of the first positioning recess 113, which will not be described again here.

[0085] A second locking portion 134 is provided at a circumferential position of the second rotating seat 130. The second locking portion 134 is arranged to extend from the outer circumference of the second rotating seat 130 towards the first rotating seat 120, and when the second rotating seat 130 is rotated to a certain angular position, the second locking portion 134 will abut against the first locking portion 124. The interaction between the second locking portion 134 and the first locking portion 124 of the first rotating seat 120 allows the second rotating seat 130 to be limited to rotate within a range of 0-180° relative to the first rotating seat 120.

[0086] A resilient member 150 is arranged between the first rotating seat 120 and the locking member 140. In the present embodiment, the resilient member 150 is a compression spring which biases the first rotating seat 120 and the locking member 140 away from each other along the axial direction. In other words, the resilient member 150 biases the first rotating seat 120 towards the base end 112 of the socket 110, and biases the locking member 140 towards the second rotating seat 130.

[0087] In this way, under the bias of the resilient member 150, the first positioning protrusion 123 of the first rotating seat 120 tends to be locked in the first positioning recess 113 of the base end 112. When the user forcibly pulls the first rotating seat 120, the first rotating seat 120 slightly moves away from the base end 112 against the bias of the resilient member 150, so that the first positioning protrusion 123 is disengaged from the first positioning recess 113. An inclined chamfer can be provided at the side edge of the first positioning protrusion 123, so as to convert the rotating force for pulling the first rotating seat 120 into an axial force, so that the first rotating seat 120 moves away from the base end 112 of the socket 110. With the relative rotation between the first rotating seat 120 and the base end 112, the first positioning protrusion 123 is aligned with a certain first positioning recess 113, at which time the first rotating seat 120 moves towards the socket 110 under the bias of the resilient member 150, and the first positioning protrusion 123 is engaged into the corresponding first positioning recess 113, thereby fixing the relative rotational position of the first rotating seat 120 and the socket 110. In this way, under the bias of the resilient member 150, the first positioning protrusion 123 of the first rotating seat 120 and the first positioning recess 113 of the socket 110 complete the positioning- relative rotation-repositioning process.

[0088] Similarly, under the bias of the resilient member 150, the second positioning protrusion 142 of the locking member 140 and the second positioning recess 133 of the second rotating seat 130 can also complete a similar positioning- relative rotation-repositioning process.

[0089] Therefore, according to the ceiling engaging device 100 of the present application, a relatively simple structure is provided, and the independent rotation and positioning of the first ceiling rod 300 and the second ceiling rod 400 are achieved by using as few components as possible.

[0090] Reference will now be made to Figures 13 to 16The following will describe how the canopy engagement device 100 according to the present application is used with the canopy 500.

[0091] As shown, the two ends of the canopy 500 are fixed to the first canopy rod 300 and the second canopy rod 400, respectively. One or more intermediate support rods 600 can also be provided at the middle of the canopy 500 to maintain the shape of the canopy 500. The intermediate support rods 600 are also arranged to rotate around the rotation axis X.

[0092] When the relative angle between the first canopy rod 300 and the second canopy rod 400 is 180°, the canopy 500 is fully unfolded, as shown in Figure 13 When the relative angle between the first canopy rod 300 and the second canopy rod 400 is other angles between 0-180°, for example, 120°, the canopy 500 is partially unfolded, as shown in Figure 14 and Figure 15 To stably maintain the canopy 500 in the partially unfolded position, the canopy 500 is provided with a folding fixation device for fixing the first canopy rod 300 or the second canopy rod 400 to the intermediate support rod 600, or for fixing one intermediate support rod 600 to another intermediate support rod 600.

[0093] For example, the folding fixation device can be a zipper 511, as shown in Figure 14 Specifically, two adjacent intermediate support rods 600 can be provided with matching zippers 511. When the canopy 500 is partially unfolded, the two intermediate support rods 600 overlap each other, at which time the zippers 511 of the two intermediate support rods 600 can be engaged, thereby fixing the canopy 500 in the partially unfolded state.

[0094] For another example, the folding fixation device can be a button 512 and a fixing ring 513, as shown in Figures 15 to 16 Specifically, the first canopy rod 300 (or the second canopy rod 400, the intermediate support rod 600) is provided with a cloth strip and a button 512 on the cloth strip, and the intermediate support rod 600 adjacent thereto is provided with a fixing ring 513. When the canopy 500 is partially unfolded, the cloth strip passes through the fixing ring 513, and the button 512 buckles the cloth strip, thereby fixing the canopy 500 in the partially unfolded state.

[0095] In summary, the present application discloses a canopy engagement device that can detachably engage a canopy to a carrier, for example, a baby bed. Moreover, the canopy engagement device allows the rotation and positioning of the two canopy rods independently of each other, thereby supporting the full unfolding and partial unfolding of the canopy.

[0096] While the preferred embodiments have been shown and described herein, it is understood that these embodiments are merely examples. Many variations, changes and substitutions will now occur to those skilled in the art without departing from the spirit of the application. It is therefore intended that the appended claims cover all such variations as fall within the spirit and scope of the application.
