Description

Load-bearing device and its usage method Technical Field

[0001] This application relates to the technical field of children's products, specifically a carrier device that is easy to unfold and operate, and a method of using the carrier device. Background Technology

[0002] Existing children's bassinets, such as the patent document with publication number CN216220972U, disclose a new type of automatically unfolding and folding bassinet, including a front frame tube (top frame) and a bottom frame. A side rail is provided between the top frame and the bottom frame. The side rail includes a first connecting tube. The upper part of the first connecting tube is hinged to the top frame, and the lower part is hinged to a sliding member. The sliding member is slidably mounted on the bottom frame. The bottom frame is provided with a fixing groove. The sliding member is movably provided with a locking pin that cooperates with the fixing groove and an unlocking member for unlocking the locking pin. Technical issues

[0003] When operating the device by a single person, one hand needs to press down on the base frame while the other hand holds and lifts the top frame. Due to the large size of the top frame, it is difficult to lift it with one hand, and the side frames on both sides are not easy to unfold synchronously, requiring repeated adjustments, which makes the operation cumbersome. Technical solutions

[0004] This application provides a support device having an open-top accommodating space and including a support frame, the support frame comprising:

[0005] A top frame defines an opening at the top of the accommodating space;

[0006] The bottom frame, arranged vertically opposite to the top frame, provides bottom support for the accommodating space;

[0007] Two paired, foldable side frames are disposed between the top frame and the bottom frame.

[0008] A first connecting seat is used to connect the two side frames. The first connecting seat is slidably mounted on the bottom frame and has a first position and a second position on the sliding path. When the first connecting seat slides between the first position and the second position, the corresponding side frame switches between a folded state and an unfolded state, while simultaneously driving the top frame and the bottom frame to align and separate.

[0009] A driving component is used to drive the first connecting seat to slide from the first position to the second position to unfold the support frame.

[0010] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.

[0011] Optionally, the supporting device includes a locking device for locking the support frame to remain in the deployed state.

[0012] Optionally, the locking device includes a locking element and an elastic element, wherein the elastic element acts on the locking element to make it constantly tend to move towards the locked state.

[0013] Optionally, when the support frame is in an intermediate state between an unfolded state and a folded state, the locking device can lock the support frame, allowing it to unfold while preventing it from folding.

[0014] Optionally, the locking device achieves locking by restricting the movement of the drive member.

[0015] Optionally, in the locked state, the locking device allows the drive member to move in the direction of unfolding the support frame, while preventing the drive member from moving in the opposite direction.

[0016] Optionally, the locking device includes a locking element and an elastic element. The elastic element acts on the locking element, causing it to constantly tend to move towards the locked state. When the driving element moves in the direction of unfolding the support frame, it drives the locking element to release. When the driving element stops moving, the locking element locks the driving element under the action of the elastic element, preventing it from moving in the opposite direction.

[0017] Optionally, the locking device includes a lock seat, the locking member is rotatably mounted on the lock seat, a channel is formed between the locking member and the lock seat for the driving member to pass through, and the locking member and the lock seat clamp and fix the driving member.

[0018] When the driving member moves in the direction of unfolding the support frame, the locking member releases the driving member. When the driving member moves in the opposite direction, the driving member drives the locking member to further clamp the driving member with the locking seat.

[0019] Optionally, the driving component is a flexible component, which extends the support frame by pulling the first connecting seat.

[0020] Optionally, the drive element is a webbing or rope.

[0021] Optionally, the driving component has a fixed end and an operating end, and the connection relationship between the driving component and the first connecting seat adopts one of the following:

[0022] a) The fixed end and the bottom frame are fixedly connected, and the operating end bypasses the first connecting seat and is located on the same side of the first connecting seat as the fixed end;

[0023] b) The fixed end is directly fixedly connected to the first connecting seat.

[0024] Optionally, the side frame includes multiple first side stops that are inclined in the same direction, and second side stops, one end of the first side stops being connected to the first connecting seat, and the other end being hinged to the top frame;

[0025] The second side stop and the first side stop are tilted in opposite directions, and one end of the second side stop is hinged to one of the first side stops, and the other end is hinged to the bottom frame.

[0026] Optionally, the support device includes a cloth bag connected between the top frame and the bottom frame, the cloth bag covering the side frame.

[0027] Optionally, the cloth bag limits the maximum height of the support frame when deployed.

[0028] Optionally, the support frame has a length direction and a width direction, with the two side frames arranged opposite each other along the width direction, and the driving member has a fixed end and an operating end, with the operating end extending out of the support frame from one end in the length direction.

[0029] Optionally, the carrying device includes a locking device for locking the drive member to maintain its extended state, the locking device being disposed adjacent to the operating end.

[0030] This application also provides a support device having a top-open accommodating space and including a support frame, the support frame comprising:

[0031] A top frame defines an opening at the top of the accommodating space;

[0032] The bottom frame, arranged vertically opposite to the top frame, provides bottom support for the accommodating space;

[0033] Two pairs of foldable side frames are arranged between the top frame and the bottom frame. When the side frames switch between a folded state and an unfolded state, they cause the top frame and the bottom frame to move closer together and separate in alignment.

[0034] A locking device that locks the support frame in an intermediate state between an unfolded state and a folded state, allowing it to unfold while preventing it from folding.

[0035] Optionally, the supporting device includes a drive member that drives the support frame from a folded state to an unfolded state.

[0036] Optionally, the locking device locks the support frame by restricting the movement of the drive member.

[0037] This application also provides a method of using the support device, including an unfolding process and a folding process:

[0038] The folding process includes: pressing down the top frame to bring it closer to the bottom frame, and tucking the side frame between the two;

[0039] The unfolding process includes: operating the drive component to cause the first connecting seat to slide, the side frame to unfold, and the top frame and the bottom frame to separate. Beneficial effects

[0040] In the unfolding operation of the bearing device of this application, the operating drive component drives the first connecting seat to slide, thereby causing the side frames on both sides to unfold synchronously, thereby causing the top frame and the bottom frame to separate from each other. Compared with the traditional structure, which requires the separation of the top frame and the bottom frame, the unfolding operation is more convenient. Attached Figure Description

[0062] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0063] It should be noted that when a component is said to be "connected" to another component, it can be directly connected to the other component or it can be connected to a component in between. When a component is said to be "set on" another component, it can be directly set on the other component or it may be set to a component in between.

[0064] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0065] In this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number or order of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0066] Referring to Figures 1-7, this application provides a support device 1000, shown as a child's bassinet, having an open-top accommodating space 190 and including a support frame 100, which has a folded state and an unfolded state. The support device 1000 may include, but is not limited to, the child's bassinet provided in this application, and may also be a children's bed, stroller, etc.

[0067] The supporting frame 100 includes a top frame 110, a bottom frame 120, paired side frames 140, a first connecting seat 130 connecting the two side frames 140, and a driving member 150. The top frame 110 defines an opening at the top of the accommodating space 190, allowing children or objects to enter and exit the accommodating space. The structure of the top frame 110 includes, but is not limited to, a closed annular frame, which is oblong in the figure. The bottom frame 120 provides bottom support for the accommodating space 190 and is arranged vertically opposite to the top frame 110.

[0068] The side frame 140 is a foldable structure and has a folded state and an unfolded state corresponding to the support frame 100. The side frame 140 is disposed between the top frame 110 and the bottom frame 120, and when folded, it drives the top frame 110 and the bottom frame 120 to align and move closer together. When unfolded, the side frame 140 drives the top frame 110 and the bottom frame 120 to align and move apart.

[0069] The first connecting seat 130 is used to connect the two side frames 140 and is slidably mounted on the bottom frame 120, having a first position and a second position on the sliding path. When the first connecting seat 130 slides between the two positions, the corresponding side frame switches between a folded state and an unfolded state. The driving member 150 is used to drive the first connecting seat 130 to slide from the first position to the second position to unfold the side frame 140.

[0070] For ease of description, this application uses the side frames shown in Figures 2-4 as an example: In the first embodiment, the X direction in the figures represents the length direction, and the two side frames 140 are arranged opposite each other along the width direction. Each side frame 140 includes a plurality of first side stops 141, each first side stop 141 being inclined in the same direction; for example, the top frame 110 and the bottom frame 120 have a certain angle between them. Alternatively, if the top frame 110 and the bottom frame 120 are parallel to each other in the figures, then the first side stops 141 are also parallel to each other. The first connecting seat 130 is connected to all the first side stops 141 to achieve synchronous movement of each first side stop 141, ensuring that the side frames 140 on both sides can be folded or unfolded synchronously.

[0071] Furthermore, the side frame 140 also includes a second side stop 142, one end of which is hinged to the first side stop 141 and the other end is hinged to the bottom frame 120. The second side stop 142 and the first side stop 141 are inclined in opposite directions, which improves the structural stability of the support frame 100 in the unfolded state.

[0072] In actual operation, when the support frame 100 is in the folded state, the operating drive unit 150 drives the first connecting seat 130 to move along the first direction, and the upper part of the first side stop 141 moves upward to drive the top frame 110 away from the bottom frame 120 until the support frame 100 is in the unfolded state; when folding, the top frame 110 is pressed down, causing the first connecting seat 130 to slide along the second direction until the support frame 100 is in the folded state. Compared with the prior art, the unfolding operation is more convenient.

[0073] The support device 1000 also includes a fabric pocket 200 connected between the top frame 110 and the bottom frame 120. The fabric pocket 200 is a flexible structure that can adapt to the unfolding and folding of the support frame. It mainly serves as a lining to provide a comfortable riding environment for the user. To improve the external aesthetics, the fabric pocket can wrap around the side frames or the entire support frame. In the unfolded state, the fabric pocket 200 is taut, pulling the top frame 110 and the bottom frame 120 so that the support frame 100 unfolds to its maximum height, indirectly restricting the first connecting seat 130 from continuing to move in the pulling direction.

[0074] The first connecting seat 130 can be a crossbar, a frame composed of multiple rods, or a component slidably fitted onto the bottom frame. For example, as shown in Figure 6, in one embodiment, the first connecting seat 130 is a frame structure, including two crossbars 131 corresponding to a pair of first side stops 141, and at least one vertical rod 132 connecting the two crossbars 131. The two ends of the crossbars 131 are slidably engaged with the bottom frame 120, while the two side frames 140 and the first connecting seat 130 are hinged. For example, a pair of first side stops 141 symmetrically arranged in the two side frames 140 are hinged to one of the crossbars 131, and another pair of first side stops 141 are hinged to the other crossbar 131. Another example is that the first connecting seat 130 includes a sliding member that slidably engages with the bottom frame 120 and a transverse member connecting the two sliding members. The first side stops 141 on the same side are hinged to the sliding member.

[0075] Furthermore, the support device 1000 also includes a locking device 160 for locking the support frame 100 to keep it in the unfolded state. The locking device can be set between the first connecting seat 130 and the bottom frame 120, that is, locking the first connecting seat 130.

[0076] In some embodiments, the locking device 160 achieves locking by restricting the movement of the driving member 150. It is important to emphasize that the locking device 160 acts on the driving member 150. In some embodiments, the driving member is a flexible component. The driving member 150 pulls the first connecting seat 130 to unfold the support frame 100. The driving member 150 is strip-shaped, wire-shaped, or a combination of both, such as nylon webbing or steel wire, or a combination of both. When the bearing device of this application unfolds, the locking device 160 acts on the corresponding position of the driving member 150 to keep the support frame 100 in the unfolded state at all times, preventing folding due to incomplete locking and thus avoiding safety accidents.

[0077] The driving component 150 has a fixed end 151 and an operating end 152. The operating end 152 is exposed outside the support frame 100, specifically extending beyond the length of the support frame 100. During the pulling and unfolding operation, the length of the operating end 152 exposed outside the support frame 100 increases. The connection relationship between the driving component 150 and the first connecting seat 130 adopts at least one of the following:

[0078] a) The fixed end 151 is fixedly connected to the bottom frame 120, and the operating end 152 bypasses the first connecting seat 130 and is located on the same side of the first connecting seat 130 as the fixed end 151 (e.g., Figure 2). Preferably, the operating end 152 bypasses one of the crossbars 131, and the outer contour of the contact part between the crossbar 131 and the driving member 150 is circular, such as a round rod, to facilitate the movement of the driving member 150.

[0079] b) The fixed end 151 is fixedly connected to the first connecting seat 130 (e.g., Figure 5).

[0080] When the support frame 100 is in an intermediate state between an unfolded state and a folded state, the locking device 160 allows the drive member 150 to move in the pulling direction (corresponding to the first connecting seat moving in a first direction), while preventing the drive member 150 from moving in the opposite direction (i.e., the retraction direction described below) (corresponding to the first connecting seat moving in a second direction). The locking device 160 has:

[0081] In the locked state, the drive component 150 is allowed to move in the pulling direction in one direction, that is, the drive component 150 is restricted from moving in the retracting direction;

[0082] In the unlocked state, the drive unit 150 is allowed to move in both directions.

[0083] The locking device 160 has a reverse-locking function. That is, when the support frame is in an intermediate state between folded and unfolded, the locking device 160 only allows the support frame to unfold and prevents it from folding, thus improving the safety of the load-bearing device. Because the locking device does not provide a warning, the operator cannot determine whether the locking was successful. If the locking is unsuccessful, the load-bearing device may fold during use. Furthermore, when the support frame is unfolded, the fabric pocket becomes taut, increasing the difficulty of locking, especially for operators with weaker strength. Adding the reverse-locking function eliminates the need to consider whether the drive component 150 has moved into position.

[0084] In some embodiments, as shown in Figures 7-9, the locking device 160 includes a lock base 161, a locking member 162, and an elastic member 165 acting on the locking member 162. A channel 163 is formed between the locking member 162 and the lock base 161 for the drive member 150 to pass through. In the locked state, the locking device 160 clamps the drive member 150 between the locking member 162 and the lock base 161, and in this state, the locking member 162 can only rotate in one direction. Specifically, the locking member 162 is rotatably mounted on the lock base 161, and an elastic member 165 (e.g., a torsion spring shown by the dashed lines in Figures 8 and 9) is provided between them. The locking member 162 has locking teeth 164, which cooperate with the lock base 161 to provide clamping force.

[0085] The locking member 162 rotates relative to the locking seat 161 and has an unlocking direction (indicated by the arrow in Figure 9) and a locking direction. As shown in Figure 9, when the operating end 152 of the driving member 150 moves in the pulling direction, a force is applied to the locking member 162 to rotate in the unlocking direction, thereby reducing or even eliminating the clamping force of the locking member 162 and the locking seat 161 on the driving member 150. As shown in Figure 8, when the operating end 152 of the driving member 150 moves in the retraction direction, a force is applied to the locking member to rotate in the locking direction, gradually increasing the clamping force of the locking member 162 and the locking seat 161 on the driving member 150, similar to self-locking. This structure realizes the aforementioned unidirectional movement of the driving member 150, allowing the locking device 160 to act at any position of the driving member 150, ensuring that the support frame is in the unfolded state, thus ignoring the influence of errors caused by processing and assembly. Before folding the load-bearing device, the locking member 162 is manually pressed to unlock it, and then pressure is applied to the top frame 110 to perform the folding operation.

[0086] The locking device 160 is located on the edge of the bottom frame 120, for example, on one side in the X direction as shown in the figure. In one embodiment, the locking member 162 is restricted from further rotation in the locking direction when locked. This restriction can be achieved by providing a limiting part on the lock seat 161 that abuts against the locking member 162. The limiting part could be a boss on the lock seat 161. In one embodiment, a connecting structure for fixing the driving member 150 is provided between the driving member 150 and the cloth pocket 200. The connecting mechanism could be a Velcro closure between the driving member 150 and the cloth pocket 200 to prevent the portion of the driving member 150 exposed outside the cloth pocket 200 from swinging freely.

[0087] In the second embodiment, as shown in FIG10, the side frame 140 includes a first sliding member 133 slidably disposed on the top frame 110, and a third side stop 143. The third side stop 143 is hinged to the first side stop 141 at or near the middle of its middle portion, with one end hinged to the first sliding member 133 and the other end hinged to the bottom frame 120. The inclination directions of the third side stop 143 and the first side stop 141 are opposite. The first sliding member 133 may be a pin connected to the third side stop 143. The corresponding top frame 110 has a groove for the pin to slide. The driving member 150 and the locking device refer to the aforementioned embodiment.

[0088] In the third embodiment, as shown in FIG11, the side frame 140 includes a second connecting seat 134 slidably disposed on the bottom frame 120 and a fourth side stop 144. The upper part of the fourth side stop 144 is hinged to the top frame 110, and the lower part is hinged to the second connecting seat 134. The fourth side stop 144 and the first side stop 141 are arranged on both sides and have opposite inclination directions. The structure of the second connecting seat 134 is the same as that of the first connecting seat 130. Furthermore, the upper parts of the fourth side stop 144 and the first side stop 141 are hinged at the same location. The structure of the second connecting seat 134 is the same as that of the first connecting seat 130, and the connection method of the driving member 150 is, for example, that the fixed end 151 is connected to the crossbar of the second connecting seat 134, and the operating end 152 bypasses the crossbar of the first connecting seat 130.

[0089] In the fourth embodiment, as shown in Figures 12 and 13, the side frame 140 comprises multiple pairs of scissor bars connected in series, with each scissor bar pivotally connected and / or slidingly engaged. Specifically, the side frame 140 is formed by two pairs of scissor bars connected in series, each pair of scissor bars consisting of two intersecting and pivotally connected connecting rods. The side frame 140 includes a first side stop 141, a fifth side stop 145, a sixth side stop 146, and a seventh side stop 147. The first side stop 141 has a first connecting seat 130 (obscured in the figure), and the fifth side stop 145 has a second sliding member 135, which is slidably mounted on the top frame 110. The second sliding member 135 can be a pin connected to the fifth side stop 145, and the corresponding top frame 110 has a groove for the pin to slide. The top of the sixth side stop 146 is hinged to the top frame 110, and the bottom of the seventh side stop 147 is hinged to the bottom frame 120.

[0090] The first side stop 141 and the fifth side stop 145 are a pair of scissor bars, and the sixth side stop 146 and the seventh side stop 147 are also a pair of scissor bars. The two pairs of scissor bars are symmetrically arranged relative to the dividing line 101. The ends of the two pairs of scissor bars are pivotally connected to each other, and this pivot point is the first pivot point 310. The pivot point of the pair of scissor bars is the second pivot point 320. Each side stop has a center point, and the pivot point of each side stop is offset to one side of the center point. This can also be understood as the line 102 connecting the center points of a pair of side stops, with all pivot points located between the two connecting lines 102. The pivot point (second pivot point 320) divides the side stop into two segments of unequal length, with the shorter segment located closer to the middle of the bearing device 1000 and the longer segment located further away from the middle of the bearing device 1000. The driving member 150 and the locking device refer to the aforementioned embodiment.

[0091] This application also provides a method of using a support device, wherein the support device adopts the support device 1000 provided in this application. The method of use includes an unfolding process and a folding process, wherein the folding process includes: pressing down the top frame 110 to bring it closer to the bottom frame 120, folding the side frame 140 and storing it between the two, and providing support to the bottom frame 120 before pressing down, for example, placing the support device 1000 on a table for folding.

[0092] The unfolding process includes: operating the driving component to slide the first connecting seat 130, unfolding the side frame 140, and simultaneously separating the top frame 110 and the bottom frame 120. When operating the driving component, pressure is applied to the bottom frame 120; for example, one hand presses against the bottom frame 120 while the other hand operates the driving component. Since the driving component is flexible, it can be quickly pulled to unfold the supporting frame 100. The cloth bag 200, in the unfolded state, indirectly restricts the flexible component from moving further in the pulling direction. The locking device 160 constantly restricts the flexible component from moving backward, making the unfolding operation more convenient and allowing for a one-step unfolding. When folding, one hand first unlocks the locking device 160 while simultaneously applying pressure to the bottom frame 120 to prevent it from moving freely, while the other hand presses down on the top frame 110.

[0093] The support device of this application, during the unfolding operation, pulls the drive component 150 to pull the first connecting seat 130 to slide, which drives the first side stop bar 141 to move to unfold the side frame, thereby driving the top frame 110 away from the bottom frame 120. Finally, when the support frame 100 is in the unfolded state, the locking device acts on the corresponding position of the flexible component to keep the support frame in the unfolded state, avoiding folding due to incomplete locking and causing safety accidents.

[0094] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
