DETAILED DESCRIPTION

[0033] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0034] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0035] Reference Figure 1 , Figure 2 and Figure 7 As shown, this disclosure discloses an exemplary embodiment of a folding guardrail, including a first guardrail 1, a second guardrail 2, a plurality of support rods 3, and a switch assembly 4. The second guardrail 2 and the first guardrail 1 are arranged parallel to each other. One end of each support rod 3 is hinged to the first guardrail 1, and the other end is hinged to the second guardrail 2, so that the folding guardrail can switch between an unfolded state and a folded state. The distance between two adjacent support rods 3 is not less than the length of each support rod 3, so that when the folding guardrail is in the folded state, the first guardrail 1, the support rods 3, and the second guardrail 2 are engaged. The switch assembly 4 is disposed on the second guardrail 2, and the switch assembly 4 is configured to lock and release the unfolded state of the folding guardrail.

[0036] In the embodiment, the first rail 1 and the second rail 2 are arranged in parallel, and the first rail 1, the second rail 2 and the plurality of support rods 3 jointly define a protection area in the unfolded state of the folding guardrail, realizing the folding and unfolding actions of the guardrail. The two ends of each support rod 3 are respectively hinged to the first rail 1 and the second rail 2, and through this hinged mode, the folding guardrail can be flexibly converted between the unfolded state and the folded state. Meanwhile, the distance between the adjacent two support rods 3 is equal to the length of each support rod 3, or the distance between the adjacent two support rods 3 is greater than the length of each support rod 3, so as to ensure that in the folded state, the second rail 2 can be buckled with the support rod 3, and the support rod 3 is buckled with the first rail 1, so that the folded guardrail structure is not only more compact, reducing the occupied space, but also increases the stability of the guardrail in the folded state, avoiding the random shaking of the support rod 3. The switch assembly 4 can be fixed in the unfolded state of the folding guardrail through a latch or a buckle; or a spring self-locking structure can be arranged, so that in the unfolded state of the folding guardrail, the spring automatically pops into the lock hole, and the folding can be realized by pressing a specific position; or a magnetic attraction type structure can be adopted, and the magnetic force is used to attract the folding guardrail in the unfolded state, so that the support rod 3 remains upright, and the folding can be realized by applying an external force when the folding guardrail is separated; or a motor or an electromagnet can be integrated, and the locking can be controlled by remote control, a key or a sensor. In actual use, when the guardrail needs to be unfolded, the second rail 2 is pulled to unfold the support rod 3, until the support rod 3 is upright and the folding guardrail reaches the unfolded state, and the unfolded state is manually operated or automatically locked according to the specific structure of the switch assembly 4; when the guardrail needs to be folded, the switch assembly 4 is first operated to unlock, and then the second rail 2 is pushed clockwise towards the first rail 1, so that the support rod 3 is rotated and folded, and finally the two sides of the support rod 3 are respectively attached to the first rail 1 and the second rail 2, completing the folding operation.

[0037] In summary, the folding guardrail of the present disclosure designs the hinged structure of the support rod 3 and the distance between the adjacent two support rods 3, so that the folding guardrail has a lower height and occupies a smaller space in the folded state, effectively saves space, is convenient for users to get on and off the bed, enhances the stability of the overall structure, and ensures the safety in use. The switch assembly 4 can be arranged at any position on the second rail 2 according to the needs of the user, which is convenient to operate and improves the user experience.

[0038] Referring to FIGS. 1 to 4, Figure 1 and Figure 2 In an implementable manner, one end of each support rod 3 is hinged to the first rail 1 through a first base 11, and the other end is hinged to the second rail 2 through a second base 21. The first base 11 and the second base 21 are shaped, and when the folding guardrail is in the folded state, the first base 11 is buckled with the second base 21 of the adjacent support rod 3.

[0039] In the embodiment, the first base 11 can be trapezoidal, triangular, square or irregular, etc., which can be designed according to actual needs, and the second base 21 is designed to be shaped with the first base 11 to ensure that the first base 11 and the second base 21 can be tightly buckled when the folding fence is in the folded state. In the embodiment shown in the disclosure, the second railing 2 is folded along the first railing 1 clockwise as an example, the left side of the first base 11 can be designed as a closed structure, so that the folding fence can be more stable when it is in the unfolded state, and the right side of the first base 11 is an open structure for the support rod 3 to rotate around the hinge point of the first base 11, and the structure of the second base 21 corresponds to the first base 11 to meet the overall folding. This design that meets the buckling requirement not only makes the folded fence structure more compact, reduces the occupied space, but also increases the stability of the fence in the folded state, avoiding the random shaking of the support rod 3. At this time, the switch assembly 4 can adopt a magnetic attraction structure, which uses magnetic force to attract the two ends of the support rod 3 to the first base 11 and the second base 21 respectively when the folding fence is in the unfolded state, and separate by applying external force. In actual use, when the fence needs to be unfolded, the second railing 2 is pulled to unfold the support rod 3 until the support rod 3 is upright and the folding fence is in the unfolded state, and the switch assembly 4 is manually operated or automatically locked in the unfolded state according to the specific structure of the switch assembly 4; when the fence needs to be folded, first operate the switch assembly 4 to unlock, then push the second railing 2 clockwise towards the first railing 1, so that the support rod 3 rotates and folds, and finally the first base 11 is buckled with the second base 21 of the adjacent support rod 3 to complete the folding operation.

[0040] Referring to Figures 3-5 In an embodiment, the switch assembly 4 includes a slide 41 and a support arm 42, the slide 41 is arranged along the length direction of the second railing 2, and the support arm 42 includes a connecting end and a sliding end, the connecting end is hinged to one of the plurality of support rods 3, and the sliding end is arranged in the slide 41. Among them, the support arm 42 and the support rod 3 form an included angle on the side close to the second railing 2 at the connecting end, and the angle of the included angle increases when the folding fence is converted from the unfolded state to the folded state.

[0041] In the embodiment, the slide rail 41 is arranged along the length direction of the second railing 2 to provide a track for the sliding of the support arm 42, so as to ensure the directionality and stability of the movement of the support arm 42. The connecting end of the support arm 42 is hinged to one of the plurality of support poles 3, so that the support arm 42 can rotate flexibly with the movement of the support pole 3. In the folding and unfolding process of the folding railing, the sliding end of the support arm 42 slides along the slide rail 41, so as to realize the accurate control of the folding process. In the unfolded state of the folding railing, the included angle between the support arm 42 and the support pole 3 is relatively small, and the support pole 3 cooperates with the support arm 42 to maintain the stable unfolding of the folding railing. When folding is needed, with the rotation of the support pole 3, the sliding end of the support arm 42 slides to the distal end in the slide rail 41, the included angle gradually increases, and the support pole 3 is further folded until it is folded in place.

[0042] Referring to Figures 4-6 In an implementable embodiment, the switch assembly 4 further includes a pressing rod 43, the pressing rod 43 is rotationally connected to the second railing 2 through a rotating shaft 44, the pressing rod 43 has a locking position and an unlocking position in the rotating direction relative to the second railing 2, when the pressing rod 43 is located at the locking position, the pressing rod 43 can limit the sliding end; when the pressing rod 43 is located at the unlocking position, the sliding end can slide along the slide rail 41.

[0043] In the embodiment, when the pressing rod 43 is located at the locking position, the pressing rod 43 can limit the sliding end of the support arm 42, so that the sliding end cannot slide along the slide rail 41, and further the support pole 3 cannot rotate at will, and the folding railing is locked in the unfolded state, providing stable and reliable protection for the user. When the pressing rod 43 is located at the unlocking position, the sliding end of the support arm 42 is no longer limited by the pressing rod 43 and can freely slide along the slide rail 41. Therefore, when the folding railing needs to be folded, the user can smoothly push the second railing 2 to make the support pole 3 drive the support arm 42 to slide, realizing the folding operation of the railing.

[0044] In an implementable embodiment, the pressing rod 43 includes a main body 431 and a stop portion 432 arranged on the main body 431, when the folding railing is in the unfolded state and the pressing rod 43 is located at the locking position, the stop portion 432 abuts against the sliding end.

[0045] In the embodiment, the main body 431 is rotationally connected to the second railing 2 through the rotating shaft 44, providing a support and connection basis for the rotation of the pressing rod 43. When the folding railing is in the unfolded state and the pressing rod 43 is located at the locking position, the stop portion 432 abuts against the sliding end of the support arm 42, effectively preventing the sliding end of the support arm 42 from sliding along the slide rail 41, and further limiting the rotation of the support pole 3, so that the folding railing is stably maintained in the unfolded state. In the folding process of the folding railing, only the pressing rod 43 needs to be rotated to the unlocking position, the stop portion 432 is separated from the sliding end, and the sliding end can freely slide along the slide rail 41, realizing the folding operation of the railing.

[0046] In an embodiment, a torsional spring 47 is arranged at the rotating shaft 44 to drive the pressing rod 43 to return to the locking position.

[0047] In the embodiment, the torsional spring 47 is sleeved on the rotating shaft 44, one end of the torsional spring 47 abuts against the pressing rod 43, and the other end abuts against the second railing 2, so that the torsional spring 47 can generate a torsional force that continuously acts on the pressing rod 43, and the pressing rod 43 has a tendency to rotate to the locking position. When the user needs to fold the guardrail, the user manually overcomes the torsional force of the torsional spring 47 and presses the pressing rod 43 to rotate the pressing rod 43 to the unlocking position, so that the sliding end of the support arm 42 can slide along the slide 41, thereby realizing the folding operation of the guardrail. It can be understood that when the sliding end leaves the locked position, the user can release the pressing rod 43, and the torsional spring 47 will immediately act to drive the pressing rod 43 to return to the locking position. Since the sliding end has left the locked position, the sliding of the sliding end will not be affected when the pressing rod 43 returns to the locking position. In the process of converting the folded guardrail from the folded state to the unfolded state, the user does not need to press the pressing rod 43, and when the sliding end slides past the stop portion 432, an external force is applied to the stop portion 432, so that the torsional spring 47 is elastically deformed. After the sliding end slides past the stop portion 432, the torsional spring 47 drives the pressing rod 43 to return to the locking position under the restoring force, and at this time, the folded state of the folded guardrail is self-locked.

[0048] In an embodiment, a transition section 433 is formed between the side of the stop portion 432 close to the rotating shaft 44 and the main body 431.

[0049] In the embodiment, the transition section 433 can be designed as an arc shape, an inclined surface or other shapes having a smooth transition effect. When the folded guardrail is converted from the folded state to the unfolded state, the transition section 433 can guide the sliding end to smoothly pass through the stop portion 432 during the sliding of the sliding end of the support arm 42 along the slide 41. Due to the existence of the transition section 433, the sliding end will not be subjected to excessive resistance when contacting the stop portion 432, and the occurrence of the jamming phenomenon is avoided, thereby enhancing the stability of the folded guardrail as a whole and prolonging the service life. When the folded guardrail is in the unfolded state and the pressing rod 43 is in the locking position, the stop portion 432 normally functions to abut against the sliding end and lock the unfolded state of the guardrail.

[0050] In an embodiment, the number of the slides 41 is two, the number of the support arms 42 is two, and the two support arms 42 correspond to the two slides 41 one by one. The two slides 41 are oppositely arranged, and a containing space for containing the pressing rod 43 is formed between the two slides 41, and the two sliding ends are connected by the sliding member 45.

[0051] In the embodiment, the two sliding tracks 41 are oppositely arranged to make the support arms 42 more evenly stressed during sliding, ensuring the stability of the folding guardrail during unfolding and folding. The sliding ends of the two support arms 42 are connected by the sliding piece 45, enhancing the cooperation between the two support arms 42 and making them keep in synchronization during sliding, ensuring the consistent action of the folding guardrail during folding and unfolding, and improving the overall stability and reliability. The sliding piece 45 can be, but is not limited to, a rivet, a screw, or a pin shaft. During unfolding or folding of the folding guardrail, the sliding ends of the two support arms 42 are synchronously slid in the respective sliding tracks 41, driving the support rod 3 to move and realizing the conversion of the guardrail. The accommodation space for accommodating the pressing rod 43 is formed between the two sliding tracks 41. Arranging the pressing rod 43 in the accommodation space not only makes full use of the space, but also makes the structure of the switch assembly 4 more compact.

[0052] In an implementable manner, the switch assembly 4 further comprises a fixed sheet metal part 46 embedded in the second guardrail 2, and the two sliding tracks 41 are formed on the fixed sheet metal part 46. The pressing rod 43 is rotatably connected with the second guardrail 2 through the fixed sheet metal part 46.

[0053] In the embodiment, the fixed sheet metal part 46, the pressing rod 43, the support rod 3, the first guardrail 1, and the second guardrail 2 work cooperatively. When it is needed to unfold or fold the guardrail, the pressing rod 43 is pressed to rotate, thereby unlocking the sliding ends of the support arms 42 to make them slide in the sliding tracks 41, realizing the unfolding or folding action of the guardrail. Since the fixed sheet metal part 46 is embedded in the second guardrail 2 and closely combined with the second guardrail 2, the stability of the entire switch assembly 4 is greatly improved, and the internal space of the second guardrail 2 is fully utilized, making the layout of the switch assembly 4 more compact.

[0054] In an implementable manner, the switch assembly 4 is arranged at the middle or both ends of the second guardrail 2.

[0055] In the embodiment, the switch assembly 4 can be arranged at any position on the second guardrail 2. When the switch assembly 4 is arranged at the middle of the second guardrail 2, the hands of the user can naturally approach the switch assembly 4, making the operation more convenient. This arrangement mode makes the operating force evenly transmitted to each part of the folding guardrail, which is beneficial to keeping the guardrail stable during unfolding and folding. When the switch assembly 4 is arranged at both ends of the second guardrail 2, the user can conveniently operate from both sides of the folding guardrail. This mode also better utilizes the space at both ends of the folding guardrail, avoiding the problem of space occupation caused by the middle arrangement, and making the overall structure more compact.
