Description

Technical Field

[0001] This utility model relates to the field of furniture, and in particular to a bed rail lifting control component and a bed rail. Background Technology

[0002] Most children's and infants' beds are equipped with bed rails that extend above the bed frame. The bed rails consist of a rail frame and a protective cover set on the rail frame. The rail frame usually includes two longitudinal guide bars and a lifting crossbar between the two longitudinal guide bars. The edge of the protective cover is fixed to the lifting crossbar to provide a protective barrier. A lifting control component is installed between the end of the lifting crossbar and each corresponding longitudinal guide bar. The lifting control component can raise the lifting crossbar to a predetermined height and maintain stability to protect the child or infant on the bed. The lifting control component can also lower the lifting crossbar to facilitate parents putting the child or infant into or taking them out of the bed.

[0003] For example, in the bed rail patent with publication number CN208540992, the switch lock includes a switch lock body, a lock cylinder, and a locking device. A slotted sleeve is connected to one side of the switch lock body, and the slotted sleeve is inserted into a crossbar. A bracket sleeve is provided on the other side, and the bracket sleeve is slidably connected to a vertical bracket. A spring is provided inside the bracket, and a ball protruding from a positioning hole is provided on the spring. A lock hole is provided at the connection between the switch lock body and the bracket sleeve. The locking device includes a switch button, which has a wedge-shaped block that drives the lock cylinder to move. When the ball is stuck in the lock hole, the crossbar remains locked. When the switch button is pressed, causing one end of the lock cylinder to pass through the lock hole, the ball is pushed out of the lock hole, and the crossbar switches to a lifting state. However, the above design has shortcomings.

[0004] The locking device in the aforementioned patent is a single locking mechanism. In actual use, children and infants may accidentally press the switch out of curiosity, causing the crossbar, which needs to be kept in a higher position, to be accidentally unlocked and switched to a free lifting state. This causes the crossbar to accidentally slide to a lower position, resulting in the bed rail losing its protective function and making it difficult to guarantee the protective and safe features of the bed rail. Summary of the Invention

[0005] This utility model provides a bed rail lifting control component and a bed rail. By arranging an unlocking component that controls the lifting or unlocking of the lifting crossbar and a safety component that controls whether the unlocking component can be unlocked smoothly at the connector, a double-safety unlocking mechanism is formed for unlocking the lifting crossbar. This prevents the lifting crossbar from falling unexpectedly due to accidental activation of the unlocking switch, thereby improving the protective and safety features of the bed rail.

[0006] The technical solution of this utility model is implemented as follows: A bed rail lifting control component includes a lifting connector and a control component. The lifting connector includes a connector head and a sliding sleeve connected to each other. The sliding sleeve has a guide groove running longitudinally through it and a locking hole extending toward the connector head. The two ends of the locking hole are respectively connected to the guide groove and the connector head. The connector head has a sliding pin corresponding to the position of the locking hole. The control component includes an unlocking component and a safety component disposed on the connector head. The unlocking component includes an unlocking switch corresponding to the position of the sliding pin and movably connected to the connector head. The safety component includes a blocking member corresponding to the position of the unlocking switch and movably connected to the connector head, and a safety switch movably connected to the connector head and corresponding to the position of the blocking member. In the initial state, the blocking component is located on the movement trajectory of the unlocking switch to block the unlocking switch from moving; when an external force is applied to the safety switch to push the blocking component, the blocking component moves and makes room for the unlocking switch to move, so that the unlocking switch can move under the action of external force and push the sliding pin to slide from the locking hole along the direction close to the guide groove.

[0007] Preferably, the unlocking switch is slidably connected to the connector head in a direction perpendicular to the axis of the sliding pin; a first driving slope is provided on one of the unlocking switch and the sliding pin, and the other of the unlocking switch and the sliding pin is pressed into contact with the first driving slope to push the sliding pin to slide.

[0008] Preferably, the blocking member is slidably connected to the connector head in a direction parallel to the axis of the sliding pin; the safety switch is slidably connected to the connector head in a direction perpendicular to the axis of the sliding pin; one of the safety switch and the blocking member is provided with a second driving inclined surface, and the other of the safety switch and the blocking member is pressed into contact with the second driving inclined surface to push the blocking member to slide.

[0009] Preferably, the safety switch includes a push-off portion that contacts the blocking member, and the push-off portion is provided with the second driving ramp. The blocking member has a clearance hole extending along the axis of the sliding pin, and the end of the clearance hole facing the opening of the push-off portion forms a contact shoulder that abuts against the second driving ramp. When an external force is applied to the safety switch and the push-off portion is inserted into the clearance hole, the second driving ramp and the contact shoulder press and push the blocking member to slide. The clearance hole design allows the safety switch to save as much space as possible occupied by the safety component while pushing the blocking member to slide.

[0010] Preferably, a first elastic element is provided between the unlocking switch and the connector. When an external force is applied to the unlocking switch to move and push against the sliding pin, the first elastic element deforms elastically. When the external force is removed, the first elastic element resets and the unlocking switch returns to its initial position.

[0011] Preferably, a second elastic element is provided between the blocking element and the connector. When an external force is applied to activate the safety switch and push against the blocking element, the second elastic element deforms elastically. When the external force is removed, the second elastic element resets and the blocking element returns to its initial position. This allows the blocking element to restrict the movement of the unlocking switch in the initial state.

[0012] Preferably, a third elastic element is provided between the safety switch and the connector. When an external force is applied to the safety switch to move and push against the blocking element, the third elastic element deforms elastically. When the external force is removed, the third elastic element resets and the safety switch returns to its initial position.

[0013] Preferably, the unlocking switch has a mating part facing the blocking member, and the blocking member is provided with a relief groove. In the initial state, the blocking member blocks the mating part, and the relief groove is misaligned with the mating part to restrict the movement of the unlocking switch. When an external force is applied to activate the safety switch and move the blocking member, the relief groove aligns with the mating part to allow the unlocking switch to move and insert into the relief groove.

[0014] Preferably, the unlocking switch has a mating portion facing the blocking member. In the initial state, the blocking member blocks the mating portion to restrict the movement of the unlocking switch. When an external force acts on the safety switch to move and the blocking member moves, the blocking member and the mating portion are offset from each other to make room for the unlocking switch to move.

[0015] A bed rail includes two longitudinal guide rods, a lifting crossbar located between the two longitudinal guide rods, and a bed rail lifting control assembly disposed between the lifting crossbar and each longitudinal guide rod; the end of the lifting crossbar facing the corresponding longitudinal guide rod is connected to a connector; a sliding sleeve slides onto the corresponding longitudinal guide rod through a guide groove; the longitudinal guide rod is provided with an elastically retractable locking pin; in the initial state, the locking pin is engaged in a locking hole and keeps the lifting crossbar locked; when an external force sequentially acts on a safety switch and an unlocking switch, the sliding pin slides along the direction close to the guide groove and pushes the locking pin out of the locking hole, so that the lifting crossbar switches to the unlocked state.

[0016] The beneficial effects of this utility model, which adopts the above technical solution, are as follows: In this invention, an unlocking switch is installed on the connector to control the sliding pin to slide and push against the locking pin to unlock the lifting bar. To prevent children from accidentally touching the unlocking switch and causing the lifting bar to unlock unexpectedly, a blocking component and a safety switch are installed on the connector. The blocking component is positioned on the movement trajectory of the unlocking switch and the sliding pin, while the safety switch can also push the blocking component to move. In the initial state, the blocking component can block the unlocking switch to restrict its movement, so even if the unlocking switch is accidentally touched at this time, the sliding pin will not move, ensuring that the lifting bar will not unlock accidentally. When unlocking is required, the safety switch must be operated first to control the blocking component to make room for the unlocking switch to move, and then the unlocking switch can be operated. Only then can the sliding pin slide and push the locking pin out of the locking hole. This double-safety control component prevents the lifting bar from accidentally falling due to accidental touch of the unlocking switch, improving the protective and safety features of the bed railing.

Detailed Implementation

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0020] This utility model has multiple embodiments, and the specific implementation methods are as follows: Example 1: As Figure 1-10 As shown, this embodiment provides a bed rail lifting control component, which is typically used in the bed rail provided in this embodiment. The bed rail typically includes two longitudinal guide rods 7 and a fixed crossbar and a lifting crossbar 8 located between the two longitudinal guide rods 7. The fixed crossbar is fixed between the two longitudinal guide rods 7, and the lifting crossbar 8 is located above the fixed crossbar. A mesh screen can be installed between the lifting crossbar 8 and the fixed crossbar to provide a protective enclosure. Figure 1-3As shown, the bed rail lifting control component in this embodiment is located between the lifting crossbar 8 and the corresponding longitudinal guide rod 7. It includes a lifting connector and a control component. The lifting connector includes a connector 1 and a sliding sleeve 2 that are connected to each other. The sliding sleeve 2 has a guide groove 21 that runs through it longitudinally. The end of the lifting crossbar 8 facing the corresponding longitudinal guide rod 7 is inserted into the connector 1. The connector 1 has a sleeve portion, and the end of the lifting crossbar 8 is fitted into the sleeve portion. The sliding sleeve 2 slides and matches the corresponding longitudinal guide rod 7 through the guide groove 21. The longitudinal guide rod 7 is provided with a retractable locking pin 71. The longitudinal guide rod 7 is a hollow tubular structure with a through hole. The locking pin 71 passes through the through hole. A spring piece connected to the locking pin 71 is usually fixedly installed inside the tubular structure to provide elastic force for the locking pin 71 to extend and retract. For the specific structure, please refer to the structure of announcement number CN208540992, which will not be described in detail here.

[0021] Specifically, the sliding sleeve 2 is provided with a locking hole 15 extending toward the connector 1. The locking hole 15 is located at the connection position between the sliding sleeve 2 and the connector 1. The two ends of the locking hole 15 are respectively connected to the guide groove 21 and the connector 1, so that the locking pin 71 can be locked into the locking hole 15. The connector 1 is provided with a sliding pin 3 corresponding to the position of the locking hole 15. The sliding pin 3 can slide along the direction close to the guide groove 21 through the locking hole 3, so that the sliding pin 3 can push out the locking pin 71 locked into the locking hole 15. The control component includes an unlocking component and a safety component provided on the connector 1. The unlocking component includes an unlocking switch 4 corresponding to the position of the sliding pin 3 and movably connected to the connector 1. The safety component includes a blocking member 5 corresponding to the position of the unlocking switch 4 and movably connected to the connector 1, and a safety switch 6 movably connected to the connector 1 and corresponding to the position of the blocking member 5. like Figure 4-7 As shown, in the initial state, the locking pin 71 engages with the locking hole 15, keeping the lifting crossbar 8 locked. The blocking member 5 is located on the movement trajectory of the unlocking switch 4 to prevent the unlocking switch 4 from moving, thus preventing the sliding pin 3 from accidentally sliding and pushing the locking pin 71 out of the locking hole, which would cause the lifting crossbar 8 to unlock accidentally, thereby improving the protection and safety of the bed railing; Figure 8-9 As shown, when the external force acts on the safety switch 6 to push against the blocking member 5, the blocking member 5 moves and makes room for the unlocking switch 4 to move, so that the unlocking switch 4 can move under the action of external force and push the sliding pin 3 to slide from the locking hole 15 along the direction close to the guide groove 21 and push the locking pin 71 out of the locking hole 15, so that the lifting bar 8 switches to the unlocked state for easy up and down movement. When the lifting bar 8 moves up and down to the initial position, the locking pin 71 is locked into the locking hole 15 again and pushes the sliding pin 3 back to the reset position.

[0022] Furthermore, this embodiment uses the example of the unlocking switch 4 and the safety switch 6 being slidably connected to the connector body 11. The unlocking switch 4 is slidably connected to the connector 1 along a direction perpendicular to the axis of the sliding pin 3. One of the unlocking switch 4 and the sliding pin 3 has a first driving inclined surface 44, and the other of the unlocking switch 4 and the sliding pin 3 is pressed against the first driving inclined surface 44 to push the sliding pin 3 to slide. Specifically, in this embodiment, the unlocking switch 4 is a push-button switch, including an unlocking switch body 43. Part of the unlocking switch body 43 protrudes outside the connector body 1 and forms an unlocking control part 41 that is easy to press. The part not protruding from the connector body 11 has a... The sliding pin 3 has a guide groove 45 extending vertically in the sliding direction. The connector body 11 has a guide part 13 corresponding to the guide groove 45. The guide part 13 is matched and connected in the guide groove 45 to provide guidance for the sliding of the unlocking switch 4. The unlocking switch body 43 is provided with the first driving slope 44. The first driving slope 44 is aligned with the end of the sliding pin 3 facing away from the card hole 15 to push the sliding pin 3 to slide. In order to further improve the smoothness of the unlocking switch 4 pushing the sliding pin 3, the corresponding end of the sliding pin 3 in this embodiment is chamfered and also forms a first driving slope 44, so that the unlocking switch body 43 and the sliding pin 3 form a surface contact, avoiding the jamming phenomenon when pressing the unlocking control part 41.

[0023] Furthermore, such as Figure 4-7 As shown, the connector 1 in this embodiment includes a connector body 11 and a cover 12. The sleeve is fixedly connected to the connector body 11, and the control component is disposed on the connector body 11. The connector body 11 and the cover 12 are fixed by buckles or screws to form a shell-like structure, so as to provide installation space for the control component and cover most of the components of the control component inside. A mounting seat 14 is provided inside the shell-like structure. The snap hole 15 extends towards one end of the connector 1 and passes through the mounting seat 14. The outer wall of the sliding pin 3 is provided with a limiting protrusion 31 facing the inner end face of the mounting seat 14. The limiting protrusion 31 can abut against the inner end face of the mounting seat 14 when the sliding pin 3 slides outward to the maximum stroke, thus preventing it from disengaging from the connector 1.

[0024] Furthermore, in this embodiment, the safety switch 6 is also a push-button switch. The connector body 11 is provided with a guide hole 17 extending perpendicularly to the axis of the sliding pin 3. The safety switch 6 includes a safety switch body and a push-off part 63 connected to the safety switch body. The safety switch body is slidably connected in the guide hole 17, so that the safety switch 6 is slidably connected to the connector 1 in a direction perpendicular to the axis of the sliding pin 3. A limiting flange is provided on the side wall of the safety switch body, and a limiting surface 16 facing the limiting flange is provided on the connector body 11. In the initial state, the limiting surface 16 abuts against the limiting flange to prevent the safety switch 6 from disengaging from the connector body 11. The safety switch body is partially exposed and forms a safety control part 61 that is easy to press. The safety switch 6 and the unlocking switch 4 can be arranged opposite each other on the connector 1, or the safety switch 6 and the unlocking switch 4 can be arranged on two adjacent side walls of the connector 1. In this embodiment, the safety switch 6 and the unlocking switch 4 are preferably arranged opposite each other so that the operator can press the safety switch 6 and the unlocking switch 4 in sequence with one hand to complete the unlocking operation more conveniently.

[0025] Furthermore, one of the safety switch 6 and the blocking member 5 is provided with a second driving ramp 64, and the other of the safety switch 6 and the blocking member 5 is in pressing contact with the second driving ramp 64 to push the blocking member 5 to slide; in this embodiment, the second driving ramp 64 is provided on the safety switch 6 for explanation, specifically, The safety switch 6 includes a push part 63 that contacts the blocking member 5, and the push part 63 is provided with the second driving inclined surface 64; the connector body 11 is provided with a guide channel 18 parallel to the axis of the sliding pin 3, and the blocking member 5 is matched and connected in the guide channel 18 so that the blocking member 5 is slidably connected to the connector 1 in a direction parallel to the axis of the sliding pin 3 to block the unlocking switch 5. Theoretically, the blocking member 5 should also have a protruding mating structure to contact the second driving inclined surface 64. However, a protruding mating structure would inevitably occupy more space, which is not conducive to a compact structure. Therefore, in this embodiment, the blocking member 5 is provided with a clearance hole 54 extending along the axial direction of the sliding pin 3. The clearance hole 54 can be a recessed deep hole or a through hole. In this embodiment, only the structure of the clearance hole 54 as a through hole is shown. The end of the clearance hole 54 facing the push part 63 forms a contact shoulder 55 that abuts against the second driving inclined surface 64. When the external force acts on the safety switch 6 and the push part 63 is inserted into the clearance hole 54, the second driving inclined surface 64 and the contact shoulder 55 press and push the blocking member 5 to slide. By providing a clearance hole 54 that allows the push part 63 to be inserted, the requirement for the blocking member 5 to contact and cooperate with the second driving inclined surface 64 is met, and the space occupied by the push part 63 is reduced.

[0026] Furthermore, in this embodiment, the contact shoulder 55 can be a prismatic structure or a planar structure. Specifically, the prismatic structure can contact the second driving slope 64 on the pushing part 63. However, in order to improve the smoothness of pressing the safety switch 6, in this embodiment, the contact shoulder 55 can also be chamfered and a second driving slope 64 can be formed so that the blocking member 5 can form a surface contact with the pushing part 63, thus avoiding jamming when pressing the safety switch 6.

[0027] Furthermore, to facilitate the reset of the unlocking switch 4 and the safety switch 6, a first elastic element 46 is provided between the unlocking switch 4 and the connector 1. When an external force is applied to the unlocking switch 4 to move and push against the sliding pin 3, the first elastic element 46 elastically deforms. When the external force is removed, the first elastic element 46 resets and the unlocking switch 4 returns to its initial position. In this embodiment, the first elastic element 46 is preferably a compression spring, but it can also be replaced with a tension spring or a spring sheet as needed. The unlocking switch 4 or the connector body 11 is provided with a locking post 52 that engages with the end of the compression spring to prevent the compression spring, which is the first elastic element 46, from undergoing large-angle bending deformation when subjected to force.

[0028] Furthermore, a second elastic element 53 is provided between the blocking member 5 and the connector 1. When an external force acts on the safety switch 6 to move and push against the blocking member 5, the second elastic element 53 elastically deforms. When the external force is removed, the second elastic element 53 resets and the blocking member 5 returns to its initial position. In this embodiment, the second elastic element 53 is preferably a compression spring, but it can also be replaced with a tension spring or a spring sheet as needed. The blocking member 5 or the connector body 11 is provided with a locking post 52 that engages with the end of the compression spring to prevent the compression spring, which is the second elastic element 53, from undergoing large-angle bending deformation when subjected to force.

[0029] Furthermore, a third elastic element 65 is provided between the safety switch 6 and the connector 1. When an external force acts on the safety switch 6 to move and push against the blocking member 5, the third elastic element 65 elastically deforms. When the external force is removed, the third elastic element 65 resets and the safety switch 6 returns to its initial position. In this embodiment, the third elastic element 65 is preferably a compression spring, but it can also be replaced with a tension spring or a spring sheet as needed. To further save space, a recessed receiving groove 62 can be provided on the safety switch 6, and the corresponding end of the compression spring can be placed in the receiving groove 62. The safety switch body or the connector body 11 is provided with a locking post 52 that engages with the end of the compression spring to prevent the compression spring, which is the third elastic element 65, from undergoing large-angle bending deformation when subjected to force.

[0030] Furthermore, in this embodiment, the unlocking switch 4 has a mating portion 42 facing the blocking member 5. The mating portion 42 is integrally formed and protrudes from the unlocking switch body 43. The blocking member 5 is provided with a relief groove 51. The relief groove 51 can be a recessed groove or a through groove. In this embodiment, only the relief groove 51 is shown as a through groove. In the initial state, the blocking member 5 blocks the mating portion 42, and the relief groove 51 is misaligned with the mating portion 42, which is equivalent to hindering the movement of the unlocking switch 4 and restricting the movement of the unlocking switch 4. When an external force acts on the safety switch 6 to move and the blocking member 5 moves, the relief groove 51 and the mating portion 42 are engaged. The safety switch 42 is aligned to allow the unlocking switch 4 to move and insert into the clearance slot 51. This design further enhances the protective effect of the bed rail. Specifically, in actual use, the operator needs to press the safety switch 6 into place and ensure that the clearance slot 51 is fully aligned with the mating part 42 in order for the blocking part 5 to make room for movement. If the pressing force is too small, the clearance slot 51 and the mating part 42 will still be misaligned. Therefore, even if a child accidentally presses the safety switch 6 and the unlocking switch 4, it will be difficult to unlock the lifting bar 8 due to insufficient pressing force, thus indirectly improving the safety of the bed rail.

[0031] Furthermore, the clearance groove 51 divides the blocking member 5 into an outer part facing the slide sleeve 2 and an inner part facing away from the slide sleeve 2. The connector body 11 is provided with a stop part 19 corresponding to the inner part. In the initial state, the stop part 19 abuts against the inner part of the blocking member 5 to prevent it from disengaging from the second elastic member 53, while keeping the blocking member 5 in the corresponding position and blocking the mating part 42, thus hindering the movement of the unlocking switch 4.

[0032] Example 2: As Figure 11 As shown, the difference between this embodiment and the above embodiment is that the blocking member 5 does not have a relief groove 51. Specifically, in the initial state, the blocking member 5 blocks the mating part 42 to restrict the movement of the unlocking switch 4. When an external force acts on the safety switch 6 to move and the blocking member 5 moves, the blocking member 5 and the mating part 42 are offset from each other, so that the blocking member 5 is completely moved out of the movement trajectory of the unlocking switch 4, so as to make room for the unlocking switch 4 to move. When the external force is removed, the blocking member 5 can be reset to the initial position and block the mating part 42 under the action of the second elastic member 53. This design eliminates the design of the relief groove 51, and can achieve the same effect as the above embodiment.

[0033] Furthermore, in this embodiment, the clearance hole 54 of the blocking member 5 can be retained, or a protruding mating structure can be provided on the blocking member 5 so that the contact shoulder 55 or the mating structure contacts the second driving inclined surface 64 on the safety switch body. At the same time, in order to stop the blocking member 5, the length of the second driving inclined surface 64 can be designed to be relatively long so that when the blocking member 5 is reset to the initial state, the second driving inclined surface 64 is in contact with the contact shoulder 55 or the protruding mating structure, restricting the blocking member 5 from disengaging from the second elastic member 53, so as to achieve the same effect as in the above embodiment.

[0034] Example 3: As Figure 12 As shown, this embodiment differs from the previous embodiment in that the unlocking switch 4 and the safety switch 6 are push-pull switches. Both the unlocking switch 4 and the safety switch 6 are slidably mounted on the connector body 11 in a direction parallel to the axis of the sliding pin 3. The first elastic element 46 is laterally mounted between the unlocking switch 4 and the connector body 11, and the third elastic element 65 is also laterally mounted between the safety switch 6 and the connector body 11, providing a reset force for the unlocking switch 4 and the safety switch 6. The blocking element 5 slides in a vertical direction perpendicular to the axis of the sliding pin 3. Connected to the connector body 11, the second elastic element 53 is also vertically arranged between the blocking element 5 and the connector body 11. In the initial state, the blocking element 5 is on the horizontal sliding track of the unlocking switch 4 to prevent it from pushing against the sliding pin 3. When the external force pushes the safety switch 6 to slide horizontally, the second driving inclined surface 64 on the safety switch 6 squeezes the blocking element 5, forcing the blocking element 5 to slide and exit the horizontal movement track of the unlocking switch 4. At this time, sliding the unlocking switch 4 can push the sliding pin 3 to slide and push out the locking pin 71 in the locking hole 15, thus completing the unlocking of the lifting crossbar 8.

[0035] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
