Description

Technical Field

[0001] The present application relates to the field of children's products, in particular to a bed guardrail. Background Art

[0002] Existing bed guardrails generally include enclosures and support legs. For easy storage, the enclosures can be folded. According to the folding direction, they can be roughly divided into two categories. One category is that the enclosure only includes crossbars and columns, and the crossbars or columns are hinged in multiple sections and can be rotated and folded, so that the enclosure can be folded and compressed in its own width direction or length direction. The other category is that the enclosure is hinged in sequence by at least three sections, such as a foldable bed fence that is easy to store with a publication number of CN 213405526 U, wherein the bed guardrail includes an enclosure mechanism and a U-shaped extension rod rotatably connected to both sides of the enclosure mechanism, and a locking mechanism is provided at the rotation connection to limit the rotation of the two. The bottom edge of the extension rod is at the same height as the bottom edge of the enclosure mechanism, and both are on the upper surface of the bed belt. If the locking mechanism at the rotation connection fails, the extension rod can rotate freely. Although the net bag set has a certain rotation restriction, there is still a large safety hazard. Summary of the invention

[0003] The present application provides a bed guardrail that is foldable and safer to use.

[0004] The present application provides a bed guardrail having an unfolded state and a folded state, comprising a fence and supporting legs, wherein the fence comprises:

[0005] At least two columns are arranged side by side, and the support foot is connected to the bottom end of a corresponding column;

[0006] A horizontal bar connected between two adjacent upright posts, wherein relative to the horizontal bar, the upright posts have a first rotation direction for switching to a folded state, and a second rotation direction for switching to an unfolded state;

[0007] The wings are connected to the columns. In the unfolded state, the crosspiece is connected between the two columns facing each other, and the wings are connected to the opposite sides of the two columns. The wings have a third rotation direction for switching to the folded state and a fourth rotation direction for switching to the unfolded state relative to the columns.

[0008] The side of the bed guardrail facing the protection area is the inner side, and the side facing away from the protection area is the outer side. When in use, the protection area has a heavy pressure object stacked on the supporting foot, and the bottom edge of the wing is blocked by the heavy pressure object to limit the movement of the wing relative to the column along the third rotation direction.

[0009] Several optional methods are also provided below, but they are not intended to be additional limitations on the above-mentioned overall solution, but are merely further supplements or preferences. Under the premise that there are no technical or logical contradictions, each optional method can be combined with the above-mentioned overall solution separately, and multiple optional methods can also be combined.

[0010] In the present application, unless otherwise specified, the positional relationship of the components involved refers to the unfolded state, and the folded state generally refers to the fully folded state. If there is an intermediate state, it will be specifically specified. When considering the actual object, the various states do not specifically refer to the current state, but should be understood as having the possibility or ability to switch to the aforementioned states.

[0011] Optionally, along the height direction of the column, the bottom surface of the supporting foot is used as a reference surface, and the bottom edge of the wing is adjacent to the reference surface.

[0012] Optionally, a side of the wing portion adjacent to the corresponding column is a connecting side, and a side away from the corresponding column is a swinging side, and the swinging side is further sunken relative to a bottom edge of the connecting side.

[0013] Optionally, the wing portion is a frame structure, and the bottom edge of the swinging side is further sunk through its own deformation.

[0014] Optionally, at the bottom edge, the connection side is slowly sunk through an arc-shaped pipeline to connect with the swing side.

[0015] Optionally, each upright post is rotationally matched with the cross bar, and relative to the cross bar, the upright post has a first rotation direction for switching to a folded state, and a second rotation direction for switching to an unfolded state;

[0016] In the unfolded state, the support legs extend in a direction away from the surface where the crossbar is located. When folded, the support legs rotate relative to the crossbar along with the upright posts where they are located. In the folded state, the support legs approach the surface where the crossbar is located.

[0017] Optionally, a first limiting mechanism is provided between the crossbar and the column, which limits the column from moving along a second rotation direction relative to the crossbar in the unfolded state;

[0018] A second limiting mechanism is provided between the column and the wing, and in the unfolded state, limits the movement of the wing relative to the column along a fourth rotation direction.

[0019] Optionally, outer sides of the column and the cross bar abut against each other, and the abutting portion thereof constitutes the first limiting mechanism. The outer sides of the wing and the column abut against each other, and the abutting portion thereof constitutes the second limiting mechanism.

[0020] Optionally, the crossbar and the column are rotatably matched via a first pivot, one of which has a convex first arc surface on the outer side of the first pivot, and the other has a matching and concave second arc surface, and an angled structure is provided on the edge of the second arc surface;

[0021] The wing and the column are rotatably matched via a second pivot, one of which has a convex third arc surface on the outer side of the second pivot, and the other has a shape-matched and concave fourth arc surface, and an angled structure is provided at the edge of the fourth arc surface.

[0022] Optionally, the surface where the supporting legs are located in the unfolded state is the supporting surface, and when folded, the supporting legs rotate within the supporting surface along with the upright posts where they are located.

[0023] The bottom edge of the wing portion of the bed guardrail of the present application is lower than the heavy object (such as a mattress) in the protection area, and the wing portion abuts against each other to limit rotation and folding, thereby eliminating the occurrence of accidental folding and improving safety in use.

[0076] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0077] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0078] In the present application, terms such as "center", "length", "width", "thickness", "top", "bottom", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "inside", "outside", "axial", and "circumferential" indicate directions or positional relationships based on the directions or positional relationships shown in certain drawings, or based on the spatial posture of the product in normal use. Of course, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the position or component referred to must have a specific direction, a specific structure and operation, and therefore cannot be understood as a limitation on the present application.

[0079] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0080] See also Figures 1 to 12 An embodiment of the present application provides a bed guardrail, including a fence 2 and a support leg 1. When in use, the support leg 1 can be inserted under the mattress, and the fence 2 is placed upright on the side of the bed. Multiple bed guardrails can be used in combination as needed to demarcate a safe area to prevent children from falling. The support leg 1 can also be placed directly flat on the bottom surface, and the fence 2 can be stably placed by the cooperation of multiple support legs.

[0081] The support leg 1 is generally a flat structure, which is convenient for being laid flat on the bottom surface or inserted under the mattress. In order to facilitate folding and reduce the volume after folding, the support leg 1 can be strip-shaped in overall shape, or at least have a coplanar structure so that it can be overlapped with the enclosure after folding.

[0082] The enclosure 2 can be a frame structure, a solid plate structure, or a barrier curtain set on the frame structure to play a protective role.

[0083] In the bed guardrail of this embodiment, the enclosure 2 includes:

[0084] At least two columns 21 are arranged side by side, and the support foot 1 is connected to the bottom end of a corresponding column 21;

[0085] A crosspiece 25 connected between two adjacent columns 21;

[0086] Each column 21 is rotationally matched with the crossbar 25, and the bed guardrail has an unfolded state and a folded state. In the unfolded state, the support leg 1 extends in a direction away from the surface where the crossbar 25 is located. When folded, the support leg 1 rotates with the column 21 on which it is located relative to the crossbar 25. In the folded state, the support leg 1 approaches the surface where the crossbar 25 is located.

[0087] Unless otherwise specified, the positional relationship of the components involved in this application refers to the unfolded state, and the folded state generally refers to the fully folded state. If there is an intermediate state, it will be specifically specified. When considering the actual object, the various states do not specifically refer to the current state, but should be understood as having the possibility or ability to switch to each state.

[0088] by Figure 1 Taking the middle direction as an example, the W direction is the length direction of the enclosure, the X direction is the thickness direction of the enclosure, and the H direction is the height direction of the enclosure.

[0089] In the unfolded state, the support leg 1 extends toward the direction away from the cross piece 25 in order to form a stable support. Therefore, the extension direction is not restricted to be perpendicular to the thickness direction of the enclosure. As long as there is an angle, a support surface can be determined. Of course, for stable support, it is preferred that the extension direction of the support leg 1 is the thickness direction of the enclosure.

[0090] In the folded state, the support leg 1 is close to the surface where the cross bar 25 is located, which can minimize the volume of the bed guardrail. The cross bar 25 itself can be approximated as a one-sided structure when the thickness is ignored. Considering the occupied space, a plane is preferably selected. Theoretically, it is difficult for the support leg 1 and the surface where the cross bar 25 are located to overlap. The closer they are to parallel, the smaller the volume after folding in the thickness direction of the enclosure. Therefore, in the folded state, the support leg 1 is preferably parallel to and attached to one side of the surface where the cross bar 25 is located.

[0091] The two adjacent columns 21 are regarded as opposite sides on the side facing away from the cross piece 25. Other structures can be arranged on the opposite sides to extend the length of the enclosure, so as to further increase the number of columns by using additional cross pieces, or to arrange wings 23, etc.

[0092] When in use, the surface where the supporting foot 1 is located is regarded as the supporting surface, such as the ground, or the bed surface, etc. When the bed guardrail of the present application is folded, the supporting foot 1 rotates within the supporting surface along with the column 21 where it is located. Taking the example of inserting the supporting foot under the mattress, when folding, it is not necessary to completely pull out the supporting foot 1, and it can be directly rotated.

[0093] Moreover, the supporting feet are always on the supporting surface when folding, so as to keep the enclosure standing as much as possible, making it easier to operate and saving operating space when folding.

[0094] In order to improve safety, the crossbar 25 and the column 21 are rotatably matched via the first hinged portion 253 , and the first hinged portion 253 is in a shielded state in the unfolded state.

[0095] Since the first hinged portion 253 is the rotational fit of the two components, there is generally a structural gap. In order to eliminate safety hazards and further ensure the stability of the unfolded state, the first hinged portion 253 is preferably shielded by other components in the unfolded state, and can be switched when folding is required. For example, the first hinged portion 253 is in an exposed state in the folded state.

[0096] Regarding the shielding of the hinged part, it is not required to be fully closed in the circumferential direction. Of course, as a preference, it is best to shield the hinged part in all directions to improve safety and ensure the locking of the hinged part.

[0097] In some embodiments, the shielding method of the first hinged portion 253 may be that the cross piece 25 is installed with a movable component, and the movable component shields the first hinged portion 253 in the unfolded state.

[0098] The movable part and the crosspiece 25 are slidably matched, rotatedly matched, or detachably matched to facilitate switching of states. In addition, in the unfolded state, the movable part acts on the crosspiece 25 and the column 21 to limit the rotation between the crosspiece 25 and the column 21. That is, the movable part locks the first hinged part 253 in the unfolded state.

[0099] In order to prevent the movable part from producing unexpected movement, a mutually cooperating positioning mechanism is provided between the movable part and the cross piece 25 to limit the relative movement range of the two.

[0100] The specific structure of the movable part can be tubular, etc. For example, a first connecting head 252 is installed on the column 21, and the first connecting head 252 is rotatably matched with the cross piece 25. The movable part is a sliding sleeve 221. In the unfolded state, the first connecting head 252 and the cross piece 25 are both restricted in the sliding sleeve 221 near the first hinged portion 253.

[0101] In order to facilitate the docking of the column 21 and the cross piece, a first connecting head 252 extending along the length direction of the enclosure 2 is fixed on the column 21. The first connecting head 252 and the cross piece 25 are rod-shaped near the first hinged portion 253, and preferably have the same cross-sectional dimensions, so that the sliding sleeve 221 can hold the first hinged portion 253 tightly after it is in place to achieve locking and avoid relative rotation of the first connecting head 252 and the cross piece 25.

[0102] The length of the sliding sleeve 221 itself is not strictly limited, and at least the locking effect of the first hinged portion 253 is guaranteed, and it is not easy to cause a large shake.

[0103] In order to ensure the locking effect and maintain the stability of the overall structure in the unfolded state, the crossbar 25 includes at least two crossbars 251 , and the sliding sleeve 221 is slidably mounted on at least one crossbar 251 .

[0104] A preferred embodiment is that a sliding sleeve 221 is installed on each cross bar 251 , and a reinforcing column 22 is connected between two sliding sleeves 221 located opposite to each other on two cross bars 251 .

[0105] The reinforcing column 22 can improve the structural strength and can also act as a linkage during operation, that is, it can simultaneously operate the two sliding sleeves 221 to move synchronously to cover or expose the first hinged portion 253.

[0106] Since the cross bar 25 is located between the two columns 21, the two ends of the cross bar 251 are connected to the columns 21 on the corresponding sides through the first hinged parts 253, and the same cross bar 251 is equipped with two sliding sleeves 221, which are respectively used to cover the first hinged parts 253 on the corresponding sides.

[0107] Since the cross bar 251 is long, it is not limited to an integral structure. It can be connected in multiple sections and even movably connected at multiple sections to increase the freedom of shape change of the bed guardrail. The movably connected parts can be shielded, protected and locked in their own way.

[0108] The reinforcing columns 22 are arranged in parallel with the upright columns 21. Or they are arranged in an oblique manner. Preferably, in the unfolded state, all the reinforcing columns 22 are coplanar with the upright columns 21 on both sides.

[0109] The first connectors 252 are configured accordingly according to the position of the crossbar 251 . For example, the top and bottom of the column 21 are both provided with first connectors 252 , and each first connector 252 is rotatably matched with a corresponding crossbar 251 .

[0110] Combination Figures 13 to 20 In some embodiments, in order to shield the first hinged portion 253, the crossbar 25 is a telescopic structure, and shields or exposes the first hinged portion 253 during the telescopic process. In combination with the above embodiments, different crossbars, or different ends of the same crossbar, can adopt the same or different shielding methods.

[0111] When the crossbar 25 adopts a telescopic structure, it generally includes at least two parts that can move relative to each other, one of which is hinged to the column 21, and the other can cover or expose the first hinged part 253 when moving.

[0112] For example, the crossbar 25 includes a crossbar inner rod 254 and a crossbar outer rod 255 that are movably connected. The crossbar inner rod 254 is rotatably matched with the column 21 through the first hinge portion 253. The crossbar outer rod 255 covers or exposes the first hinge portion 253 when moving relative to the crossbar inner rod 254.

[0113] In order to facilitate the connection between the upright post 21 and the crossbar, a first connector 252 is installed on the upright post 21 , and the first connector 252 is rotatably matched with the crossbar inner rod 254 through the first hinged portion 253 .

[0114] The crossbar inner rod 254 and the crossbar outer rod 255 may be matched in such a way that the crossbar inner rod 254 is slidably inserted into the crossbar outer rod 255 .

[0115] A mutually cooperating positioning mechanism is provided between the inner crossbar rod 254 and the outer crossbar rod 255 to limit the relative movement stroke of the two.

[0116] Similar to the function of the sliding sleeve, in the unfolded state, the crossbar outer rod 255 locks the first hinged portion 253 .

[0117] That is, in the unfolded state, the crossbar outer rod 255 is sleeved outside the first hinged portion 253 to limit the rotation between the first connector 252 and the crossbar inner rod 254 .

[0118] Since the crossbar 25 is located between two upright posts 21 , correspondingly, crossbar inner posts 254 are respectively installed at both ends of each crossbar outer post 255 for connecting with the upright posts 21 on the corresponding side.

[0119] In order to ensure the locking effect and maintain the stability of the overall structure in the unfolded state, the crossbar 25 includes at least two crossbars 251, each of which includes an inner crossbar 254 and an outer crossbar 255, and a reinforcing column 22 is connected between the outer crossbars 255 of the two crossbars 251.

[0120] The first connector 252 is fixedly mounted on the column 21 . Specifically, for example, a connecting sleeve 212 is fixed on the column 21 , and the first connector 252 is fixed in the connecting sleeve 212 .

[0121] The crossbar 251 does not require a separate rod member, and can also be provided by the edge of a plate member to guide the sliding sleeve 221 or to accommodate the crossbar inner rod 254.

[0122] The “rod” members mentioned in each embodiment may be hollow or solid at different locations without any strict limitation as long as the strength requirements are met.

[0123] In order to further expand the bed guardrail, in some embodiments, the enclosure 2 further includes at least one wing portion 23 , and the wing portion 23 is connected to a side of the column 21 facing away from the cross bar.

[0124] In the unfolded state, the wing 23 is coplanar with the crosspiece 25, and is extended in the length direction of the enclosure. In order to further reduce the size after folding, the upright 21 and the wing 23 are rotated and matched. In the unfolded state, the wing 23 is coplanar with the crosspiece 25, and in the folded state, the wing 23 and the crosspiece 25 overlap each other. In this way, in the length direction of the enclosure, the wing 23 will not occupy the space outside the crosspiece 25 after folding.

[0125] In the various figures of the present application, the columns 21 and the wings 23 adopt a symmetrical structure in the length direction of the enclosure, so the marking and structural description take one side as an example, and the other side is the same, but in fact, there is no strict restriction on the use of a symmetrical structure.

[0126] When a symmetrical structure is adopted, there are two upright posts 21 , the cross piece 25 is located at the opposite sides of the two upright posts 21 , and there are two wing portions 23 , which are respectively connected to the opposite sides of the two upright posts 21 .

[0127] The wing 23 and the column 21 are rotatably matched via the second hinged portion 233 , and the second hinged portion 233 is in a shielded state in the unfolded state.

[0128] In the folded state, the second hinged portion 233 is in an exposed state.

[0129] The principle and function of shielding and exposing the second hinged portion 233 are the same as those of the first hinged portion 253 .

[0130] For easy installation, the column 21 is installed with a second connector 231 , and is rotatably matched with the wing 23 through the second connector 231 .

[0131] The second hinged portion 233 is shielded and exposed by using the sliding sleeve 221 mentioned in the above embodiments, or the wing portion 23 is a telescopic structure, and the second hinged portion 233 is shielded during the telescopic movement.

[0132] For example, a sliding sleeve is installed on the wing 23, and the sliding sleeve covers the second hinged portion 233 in the unfolded state. And the second hinged portion 233 is locked by the sliding sleeve in the unfolded state.

[0133] For example, the wing 23 is a telescopic structure, and the second hinged portion 233 is shielded or exposed during the telescopic process.

[0134] In conjunction with the accompanying drawings, the wing 23 includes a wing inner rod 232 and a wing outer rod 234 that are movably connected. The wing inner rod 232 and the column 21 are rotationally matched through the second hinge part 233. The wing outer rod 234 covers or exposes the second hinge part 233 when moving relative to the wing inner rod 232.

[0135] A second connector 231 is installed on the column 21 , and the second connector 231 is rotatably matched with the wing inner rod 232 via a second hinged portion 233 .

[0136] The wing inner rod 232 is slidably inserted into the inner part of the wing outer rod 234. A mutually cooperating positioning mechanism is provided between the wing inner rod 232 and the wing outer rod 234 to limit the relative movement stroke of the two.

[0137] When in use, there is no strict restriction on the order in which the first hinged portion 253 and the second hinged portion 233 are exposed and covered, and they can be operated sequentially or even simultaneously according to the principle of on-site location or convenience of operation.

[0138] The wing 23 itself may also adopt a frame or plate structure to ensure strength, and preferably has a smoothly transitioned corner. For example, the wing 23 has a U-shaped outer frame, and the two ends 11 of the U-shape are hollow structures and serve as wing outer rods 234. The wing inner rods 232 are movably inserted in the hollow structure.

[0139] In order to facilitate docking with the column 21 , the top and bottom of the column 21 are both provided with second connectors 231 , and the two ends 11 of the U-shape are respectively connected to the corresponding second connectors 231 through the wing outer rods 234 .

[0140] To ensure that the wing 23 matches the crosspiece 25 in structure and appearance, the first connector 252 and the second connector 231 are aligned with each other in the height direction of the column 21 .

[0141] Preferably, a connecting sleeve 212 is fixed on the column 21 , and the first connecting head 252 and the second connecting head 231 , which are flush with each other, are an integral part and are fixed in the connecting sleeve 212 .

[0142] An integrated component is easier to process and install, and the fixing method in the connecting sleeve 212 can use pins, fasteners or snaps, etc. The connecting sleeve 212 can be a separately configured component, and its structural function can also be realized by perforating the column 21.

[0143] To ensure neatness after folding, the first connecting head 252 and the second connecting head 231 have the same length.

[0144] The U-shaped opening is placed horizontally and faces the column 21 , and the two ends of the U-shape are respectively flush with one of the cross bars 251 in height.

[0145] As can be seen in the figure, the rotation axes of the first hinged part 253 and the second hinged part 233 are parallel to each other. The rotation axis of the first hinged part 253 is L1, and the rotation axis of the second hinged part 233 is L2, and both are parallel to the height direction of the enclosure.

[0146] Correspondingly, the extension direction of the first connecting head 252 and the second connecting head 231 is L3. In the unfolded state, L3 is parallel to the length direction of the enclosure, and in the folded state, L3 is parallel to the thickness direction of the enclosure.

[0147] In the unfolded state, the support leg 1 extends in the direction of the thickness of the enclosure, and in the folded state, the support leg 1 extends in the direction of the length of the enclosure. As for the crossbar 25 and the wing 23, whether it is a sliding sleeve or a telescopic structure, a reset mechanism can be configured respectively. When the bed guardrail is reset from the folded state to the unfolded state, the reset mechanism acts on the sliding sleeve or the telescopic structure to cover the first hinged portion 253 and the second hinged portion 233 again.

[0148] In order to avoid setting up additional joints and reduce installation risks, the column 21 and the support leg 1 maintain the same angle in the unfolded state and the folded state.

[0149] The column 21 and the support leg 1 remain relatively fixed when the bed guardrail state is switched, which can improve the overall strength. As for the angle problem, since one is placed horizontally and the other is placed vertically during use, the column 21 and the support leg 1 are perpendicular to each other.

[0150] The support foot 1 is fixed to the bottom end of the column 21. Preferably, the support foot 1 is rigidly fixed to the bottom end of the column 21. The connection strength can be improved and the overturning deformation of the enclosure 2 can be reduced during use.

[0151] The interior of the column 21 is provided with a slidably mounted extension portion 211 , which can extend from the bottom end of the column 21 and adjust the height, and the support foot 1 is fixed to the bottom end of the extension portion 211 .

[0152] The column 21 further includes a locking mechanism 242 for maintaining the position of the extension portion 211 .

[0153] In the present application, since the upright column 21, the cross bar 25, and the wing portion 23 can rotate relatively, the volume is small in the folded state, and the positional relationship of each component after folding is further improved.

[0154] For example, in the folded state, the two wings 23 are overlapped on the same side of the crosspiece 25. Preferably, in the folded state, the two wings 23 are coplanar and parallel to the crosspiece 25.

[0155] The vertical line between the two columns 21 is in the length direction of the enclosure. Along the length direction of the enclosure, in the folded state, the two wings 23 and the cross bar 25 are located between the two columns 21 .

[0156] In the folded state, the two wings 23 are arranged in sequence along the length direction of the enclosure.

[0157] The two wings 23 are arranged in sequence along the length direction of the enclosure and are adjacent to each other. As can be seen in the figure, the U-shaped bottom is basically close to each other.

[0158] Correspondingly, in the length direction of the enclosure 2 , the length of the crosspiece 25 is equal to the sum of the lengths of the two wing portions 23 .

[0159] In the folded state, the two wings 23 are overlapped on the same side of the cross piece 25 along the thickness direction of the enclosure, and the first connector 252 and the second connector 231 both extend along the thickness direction of the enclosure.

[0160] In the folded state, along the thickness direction of the enclosure, the upright post 21 is located between the cross piece 25 and the wing portion 23 .

[0161] In the folded state, along the thickness direction of the enclosure, the support foot 1 is between the cross piece 25 and the wing 23 .

[0162] One end of the support leg 1 is a root 12 connected to the column 21, and the other end is an end 11. In the folded state, the ends 11 of the two support legs 1 are adjacent to, against or overlap each other.

[0163] refer to Figures 21 to 34 As shown, in some embodiments, a bed guardrail is provided, including a fence and a support leg, wherein the fence includes:

[0164] At least two columns are arranged side by side, and the supporting feet are connected to the bottom end of a corresponding column;

[0165] A horizontal bar connected between two adjacent columns;

[0166] Each column and the crossbar are rotated together, and the bed guardrail has an unfolded state and a folded state. In the unfolded state, the support legs extend in the direction away from the crossbar, and in the folded state, the support legs rotate with the columns they are on relative to the crossbar, and in the folded state, the support legs approach the crossbar.

[0167] Relative to the cross bar 25, the column 21 has a first rotation direction 41 for switching to a folded state, and a second rotation direction 42 for switching to an unfolded state; a first limiting mechanism 256 is provided between the cross bar 25 and the column 21, which limits the movement of the column 21 relative to the cross bar 25 along the second rotation direction 42 in the unfolded state.

[0168] The unfolding and folding characteristics of the bed guardrail are similar to those of the above embodiments. In this embodiment, improvements and limitations are mainly made on the connection and limiting method between the crossbar 25 and the column 21.

[0169] Relative to the cross bar 25, the column 21 has a relative first rotation direction 41 and a second rotation direction 42. In the unfolded state, if the column 21 can be folded in the opposite direction (i.e., move along the second rotation direction 42), the extension direction of the supporting foot will change, which is not conducive to the stable standing of the fence as a whole, posing a safety hazard. Therefore, a first limiting mechanism is provided.

[0170] As for the first limiting mechanism itself, it acts between the column and the crossbar, and can be a separate component or a part of the column and / or the crossbar.

[0171] In order to further expand the protection area and make the enclosure flexible in shape, refer to Fig. 27 , Fig.28 Fig.34 As shown, in some embodiments, a bed guardrail is provided, including a fence and a support leg, wherein the fence includes:

[0172] At least two columns are arranged side by side, and the supporting feet are connected to the bottom end of a corresponding column;

[0173] A horizontal bar connected between two adjacent columns;

[0174] The wings are connected to the columns. In the unfolded state, the crossbar is connected between the two columns facing each other, and the wings are connected to the opposite sides of the two columns.

[0175] The bed guardrail has an unfolded state and a folded state. In the unfolded state, the support legs extend in a direction away from the surface where the crossbar is located. In the folded state, the support legs rotate with the uprights where they are located relative to the crossbar. In the folded state, the support legs approach the surface where the crossbar is located.

[0176] Each upright post 21 is rotatably matched with the crossbar 25 and the wing 23 through corresponding hinged parts to switch the state of the bed guardrail.

[0177] Ignoring the width of the column, the fence in the figure can be regarded as three parts that can be relatively folded, namely the cross bar and the two wings. These three parts can be in a coplanar state (expanded state) or folded into an L shape or U shape. The extension direction of the supporting legs can be changed accordingly as needed to obtain a stable standing posture.

[0178] In a preferred embodiment, relative to the column 21, the wing 23 has a third rotation direction 43 for switching to the folded state, and a fourth rotation direction 44 for switching to the unfolded state; a second limiting mechanism 235 is provided between the column 21 and the wing 23, which limits the movement of the wing 23 relative to the column 21 along the fourth rotation direction 44 in the unfolded state. The second limiting mechanism can be the same as the first limiting mechanism in principle and structural features, or they can be independent of each other.

[0179] refer to Figures 21 to 34 As shown, in some embodiments, a bed guardrail is provided, including a fence and a support leg, wherein the fence includes:

[0180] At least two columns are arranged side by side, and the supporting feet are connected to the bottom end of a corresponding column;

[0181] A horizontal bar connected between two adjacent columns;

[0182] Each column and the crossbar rotate together, and the bed guardrail has an unfolded state ( Fig.21 and Fig. 22 shown) and folded state ( Fig.32 and Fig.33 As shown), in the unfolded state, the support legs extend in the direction away from the surface where the crossbar is located, and when folded, the support legs rotate with the uprights where they are located relative to the crossbar, and in the folded state, the support legs approach the surface where the crossbar is located;

[0183] Each column, crossbar and corresponding wing part are respectively rotated and matched through corresponding hinged parts to switch the state of the bed guardrail. In the unfolded state, each column, crossbar and corresponding wing part abut against each other at the hinged parts to limit the reverse folding of each other.

[0184] Folding in opposite directions to each other, combined with the foregoing, can be understood as limiting the movement of the column 21 relative to the cross piece 25 along the second rotation direction 42 in the unfolded state; limiting the movement of the wing 23 relative to the column 21 along the fourth rotation direction 44.

[0185] Along the height direction of the column 21, the bottom surface of the support foot 1 is used as a reference surface, and the bottom edge of the wing is adjacent to the reference surface. The bottom edge of the wing is at the same height as the reference surface, or slightly higher than the reference surface.

[0186] The bottom edge of the wing is adjacent to the reference surface and can still effectively shield the protection area when the height of the fence top changes. In addition, objects inside the protection area can also be used to indirectly limit the movement of the wing 23 along the third rotation direction 43 to maintain the effective area of ​​the protection area.

[0187] For example, for an object (a mattress) having a certain thickness, the bottom edge of the wing 23 is lower than the upper surface of the mattress, so that the side wall of the mattress abuts against the wing 23 to limit the movement of the wing 23 along the third rotation direction 43 .

[0188] When the bottom edge of the wing portion 23 is higher than the reference surface, the height difference with the reference surface is less than 20 mm, so as to adapt to the mattress with a minimum thickness of 50 mm on the market.

[0189] The connection relationship between the wing 23 and the column 21 is that the side of the wing 23 adjacent to the corresponding column 21 is the connecting side 236, and the side away from the corresponding column 21 is the swinging side 237, and the swinging side 237 is further sunken relative to the bottom edge of the connecting side 236 to approach the reference surface.

[0190] In some embodiments, the support foot can be raised and lowered relative to the column, the support foot 1 itself has a certain thickness, or other components are arranged between the support foot 1 and the bottom edge of the column 1, so that there is a certain height difference between the bottom edge of the column 1 and the reference surface, and the connecting side 236 is arranged adjacent to the column 1. Therefore, the bottom edges of the connecting side 236 and the column 1 are at the same height, or the bottom edge of the connecting side 236 is higher, and the bottom edge of the connecting side 236 is always higher than the reference surface, and then the swing side 237 can only be further sunk relative to the bottom edge of the connecting side 236 to approach the reference surface, which should be understood as the state when the support foot and the column are retracted to the extreme position.

[0191] The wing 23 deforms itself to further sink the bottom edge of the swing side 237 and generate a certain height difference with the bottom edge of the connection side 236. At the bottom edge, the connection side 236 slowly sinks through the arc-shaped pipeline to connect with the swing side 237, thereby enhancing the connection strength between the connection side 236 and the swing side 237. The preferred height difference range is 30 mm to 57 mm, ensuring the contact area between the swing side 237 and the object in the protection zone.

[0192] The side of the bed guardrail facing the protection area is the inner side, and the side facing away from the protection area is the outer side. When in use, the protection area has a heavy pressure object 3 stacked on the supporting foot 1, and the bottom edge of the wing 23 is blocked by the heavy pressure object 3 to limit the movement of the wing 23 relative to the column 21 along the third rotation direction 43.

[0193] The side of the bed guardrail facing the protection area is the inner side, and the side facing away from the protection area is the outer side. In the unfolded state, the outer sides of the column 21 and the cross bar 25 abut against each other, and the abutting part of the two constitutes the first limiting mechanism 256.

[0194] The side of the bed guardrail facing the protection area is the inner side, and the side facing away from the protection area is the outer side. In the unfolded state, the outer sides of the wing 23 and the column 21 abut against each other, and the abutting part of the two constitutes a second limiting mechanism 235.

[0195] In order to enhance the strength between the abutting parts and reduce the stress damage between the abutting parts, the abutting surfaces of the two abutting parts are arc surfaces with complementary shapes. For example:

[0196] refer to Fig.34 and Fig.35 As shown, in the unfolded state, the first arc surface 258 fits with the second arc surface 259 , and when the column 21 rotates along the first rotation direction 41 , the two arc surfaces separate from each other.

[0197] In the unfolded state, the third arc surface 239 fits with the fourth arc surface 240 , and when the wing portion 23 rotates along the third rotation direction, the two arc surfaces separate from each other.

[0198] The crosspiece 25 and the column 21 are rotatably matched via a first pivot 257, one of which has a convex first arc surface 258 on the outside of the first pivot 257, and the other has a matching and concave second arc surface 259, and the edge of the second arc surface 259 has a cut-off structure 241 to prevent the tip from being exposed and causing safety hazards.

[0199] The wing 23 and the column 21 are rotatably matched via a second pivot 238 , one of which has a convex third arc surface 239 on the outer side of the second pivot 238 , and the other has a matching and concave fourth arc surface 240 , with a cut-angle structure 241 on the edge of the fourth arc surface 240 .

[0200] See also Figure 36 to Figure 41 In one embodiment, the crossbar 25 includes a first frame structure, which is hollow inside and roughly rectangular. In one embodiment, the first frame structure includes two crossbars 251 connected to the column 21, which are an upper crossbar and a lower crossbar parallel to each other, and the two crossbars 251 are respectively connected to the upper part and the lower part of the column.

[0201] Part of the inner edge of the first frame structure is in close contact with the side of the mattress, or the mattress relies on its own elasticity to extend under the first frame structure and contact its bottom edge. The first support plate 271 is made of aluminum alloy or other hard materials such as hard plastic, which reinforces the structural strength of the first frame structure and prevents the caregiver from leaning on it and deforming it. In addition, the first support plate 271 is in the protection area. Combined with the aforementioned assembly method of the first frame structure and the mattress, the bottom edge of the first support plate 271 can effectively press against the top of the mattress by relying on its own thickness, covering the assembly gap between the bed guardrail and the mattress, and eliminating the safety hazard of children pinching their hands and heads.

[0202] At the same time, in order to prevent children from being injured by collision with the first support plate 271 made of rigid material, a first protective pad 272 is installed against the inner side of the first support plate 271. The first protective pad 272 can be made of other flexible materials such as sponge or silicone, which can provide a buffer for children and improve safety in use. The first protective pad 272 is arranged against the first support plate 271 to reduce the deformation of the first protective pad 272. Compared with the traditional net bag structure, the rebound force is correspondingly reduced to prevent children from being injured, thereby further improving safety in use.

[0203] In one embodiment, the wing 23 includes a second frame structure, and a second support plate 273 made of a rigid material and a second protective pad 274 made of a flexible material are installed on the inner side of the second frame structure. The arrangement and material properties between the second support plate 273 and the second protective pad 274 are similar to the arrangement and corresponding material properties between the first support plate 271 and the first protective pad 272, which strengthens the structural strength of the wing 23 and obtains more effective safety protection, so that the inner side of the bed guardrail is safely protected and the structure is strengthened. When the bed guardrail is folded, the two support plates and the two protective pads are located between the crossbar 25 and the wing 23, and do not need to be disassembled, which is convenient for packaging and transportation and user use.

[0204] In one embodiment, the bed guardrail includes a first cloth bag 275 covering the first support plate 271 and the first protective pad 272 to combine the two, and a second cloth bag 276 covering the second support plate 273 and the second protective pad 274 to combine the two, eliminating the need for gluing or binding, and is easy to install, disassemble and clean.

[0205] In one embodiment, the enclosure 2 is provided with an elastic cloth cover 264 covering the enclosure 2 and the first cloth pocket 275 and the second cloth pocket 276, covering all the above-mentioned components except the supporting leg 1, and the appearance is more concise.

[0206] In one embodiment, the first support plate 271 is inclined relative to the plane where the first frame structure is located, and / or the second support plate 273 is inclined relative to the plane where the second frame is located. The inclined arrangement is such that the two support plates gradually move away from the corresponding plane from top to bottom.

[0207] The edge of the two crossbars 251 facing the protection zone is the plane where the first frame structure is located, and is defined as the first vertical plane, which is perpendicular to the reference plane. The first support plate 271 itself has a certain thickness, and the plate surface facing the protection zone is parallel or inclined relative to the first vertical plane.

[0208] The first support plate 271 is fixedly arranged on the side of the crosspiece 25 facing the protection zone. When arranged in parallel, one side of the first support plate 271 can be close to the first vertical surface and extend into the protection zone by virtue of its own thickness. Alternatively, it can be arranged at a certain distance from the first vertical surface. When arranged in an inclined manner, the bottom edge of the first support plate 271 is spaced a certain distance from the first vertical surface and extends into the protection zone. In the above arrangement, the bottom edge of the first support plate 271 presses against the mattress in the protection zone to cover the assembly gap between the crosspiece 25 and the mattress, thereby reducing safety hazards.

[0209] Similarly, the edge of each wing 23 facing the protection zone is the plane where the second frame structure is located. The second support plate 273 itself has a certain thickness. The plate surface parallel to or inclined relative to the second vertical surface is the plate surface facing the protection zone.

[0210] The second support plate 273 is fixedly arranged on the side of the wing 23 facing the protection zone. When arranged in parallel, one side of the second support plate 273 can be close to the second vertical surface and extend into the protection zone by virtue of its own thickness. Alternatively, it can be arranged at a certain distance from the second vertical surface. When arranged at an angle, the bottom edge of the second support plate 273 is spaced a certain distance from the second vertical surface and extends into the protection zone. In the above arrangement, the bottom edge of the second support plate 273 presses against the mattress in the protection zone to cover the assembly gap between the wing 23 and the mattress, thereby reducing safety hazards.

[0211] The bottom edge of the second support plate 273 is close to or has the same height as the bottom edge of the connecting side 236 , so that the mattress can press against the swinging side 237 that is sunken relative to the connecting side 236 .

[0212] The second support plate 273 is arranged in the same manner as the first support plate 271, for example, in parallel or inclined arrangement, and the plate surface facing the protection area is flush, which makes the appearance more beautiful. Preferably, the two vertical surfaces are in the same plane to facilitate the arrangement of the two support plates.

[0213] Among them, the first frame structure is provided with a first mounting seat 261 for raising the bottom of the first support plate 271, and the second frame structure is provided with a second mounting seat 262 for raising the bottom of the second support plate 273. The first support plate 271 is fixedly connected to the first mounting seat 261, and the first mounting seat 261 and the crossbar 25 can be detachably connected and fixed by welding or bolting. If the first support plate 271 is tilted, a plurality of first mounting seats 261 are only arranged horizontally along the lower part of the crossbar 25 corresponding to the lower crossbar 251, and the lower part of the first support plate 271 is connected and fixed with the first mounting seat 261 by bolts, and the upper part is fixedly connected with the upper crossbar 251. The protruding height of the first mounting seat 261 determines the inclination angle and the extension length of the first support plate 271, which is convenient for measuring and manufacturing. Of course, first mounting seats 261 with different protruding heights can also be arranged on the upper and lower parts of the crossbar 251.

[0214] The upper and lower parts of the crosspiece 25 are provided with the same first mounting seat 261 , and the first supporting plates 271 are provided in parallel.

[0215] Similarly, if the second support plate 273 is tilted, the second mounting seat 262 is only provided at the lower part of the wing 23, corresponding to the connection side 236 and the swing side 237 at the same height as the connection side 236. The lower part of the second support plate 273 is connected and fixed to the second mounting seat 262 by bolts, and the upper part is directly fixed to the wing 23. The raised height of the second mounting seat 262 determines the inclination angle and the extension length of the second support plate 273. Of course, the second mounting seats 262 with different raised heights can also be provided at the upper and lower parts of the wing 23.

[0216] The upper and lower parts of the wing 23 are provided with the same second mounting seat 262 , and the second supporting plates 273 are provided in parallel.

[0217] The two vertical surfaces are the same plane, the first mounting seat 261 and the second mounting seat 262 have the same specifications and are arranged in the same manner, so that the arrangement of the two support plates is consistent.

[0218] In one embodiment, the bottom edges of the first support plate 271 and the second support plate 273 extend at least 10 mm inwardly of the bed guardrail, plus the thickness of the second support plate of at least 5 mm, for a total of 15 mm to effectively shield the assembly gap and maintain the protection zone space.

[0219] In some embodiments, the two support plates are provided with countersunk holes corresponding to the mounting seats on the side facing the protection area (not shown in the assembled state), and elastic plugging caps 263 are provided for sealing the countersunk holes to reduce safety hazards.

[0220] An embodiment of the present application further provides a bed guardrail, comprising a fence 2 and a support leg 1, wherein the fence 2 comprises:

[0221] Two columns 21 are arranged side by side, and the support foot 1 is connected to the bottom end of a corresponding column 21;

[0222] A crosspiece 25 connected between the opposite sides of the two uprights 21;

[0223] A wing portion 23 connected between opposite sides of the two uprights 21;

[0224] The bed guardrail has an unfolded state and a folded state. Each upright column and the crossbar 25 and the wing 23 are rotated and matched through corresponding hinged parts to switch the state of the bed guardrail. In the unfolded state, each hinged part is covered, and in the folded state, each hinged part is exposed.

[0225] In the unfolded state, each hinged part is locked, and in the folded state, each hinged part is unlocked.

[0226] The specific structure of the enclosure 2 and the supporting leg 1, as well as the shielding, exposure, locking, etc. of the hinged parts can be combined with the above embodiments.

[0227] In combination with different folding states of the bed guardrail, an embodiment of the present application further provides a U-shaped bed guardrail, including a fence 2 and a support leg 1, wherein the fence 2 includes:

[0228] Two columns 21 are arranged side by side, and the support foot 1 is connected to the bottom end of a corresponding column 21;

[0229] A crosspiece 25 connected between the opposite sides of the two uprights 21;

[0230] A wing portion 23 connected between opposite sides of the two uprights 21;

[0231] Each column 21 is rotatably matched with the crossbar 25 and the wing 23. The bed guardrail has a working state and a folded state. In the working state, each wing 23 and the crossbar 25 form a U-shape, and the two columns 21 serve as two turning points at the bottom of the U-shape. Each support leg 1 extends from the corresponding turning point to the inside of the U-shape. In the folded state, the support leg 1 rotates with the column 21 where it is located relative to the crossbar 25, and is stacked on one side of the crossbar 25 together with each wing 23. During the folding process, the bed guardrail of the present application also has a state in which a single wing 23 is half-folded and forms an L-shape with the crossbar 25.

[0232] Of course, in order to keep the wing 23 and the crosspiece 25 in a U shape, a corresponding locking structure may be provided between the two.

[0233] The U-shaped state can be seen in Fig.17 ,as well as Figure 23 to Figure 26 As shown, the wings 23 and the crossbar 25 form a U-shape when viewed from the height direction of the enclosure, and the two support legs 1 point to the inside of the U-shape in the support surface, with an angle of about 30 to 60 degrees with the crossbar.

[0234] A locking mechanism 242 is disposed between each column 21 and the crossbar 25 and the wing 23 to maintain the unfolded state.

[0235] The specific structure of the enclosure 2 and the supporting leg 1, as well as the shielding and exposure of the hinged portion can be combined with the relevant details of the bed guardrails in the above embodiments. Of course, the aforementioned bed guardrail can also form a U-shaped bed guardrail in a semi-folded state.

[0236] The U-shape may be understood to include similar C-shape, semicircle, etc. The turning point does not require a sudden change in the extension path, and the focus is on the position of the column 21.

[0237] The wing of the bed guardrail of the present application is partially sunken, so that the heavy pressure in the protection area can abut against the sunken part, limiting the folding and rotation of the wing, keeping the bed guardrail in a straight unfolded state, eliminating the accident of accidental folding, and improving the safety of use. It is also possible to abandon the locking mechanism at the bottom of the rotational matching part, and only rely on the locking mechanism at the top and the heavy pressure to limit the bottom to maintain the unfolded state, saving costs.

[0238] The present application also provides a folding method for a bed guardrail, the bed guardrail includes a fence 2 and support legs 1, the fence 2 includes a plurality of sections hinged in sequence in its length direction, each support leg 1 is fixed to a corresponding section thereof, in the unfolded state, the sections of the fence are coplanar, the support legs extend in a direction away from the surface of the fence, and when stacked, adjacent sections rotate relative to each other, so that the sections of the fence 2 are stacked and all the support legs 1 are parallel to each other, approaching the surface of one of the sections of the fence.

[0239] In combination with the above, the multiple sections are a crossbar 25, a column 21 hinged on both sides of the crossbar 25, and a wing 23 hinged on the back side of the two columns 21. In the unfolded state, regardless of the thickness of each section, the crossbar 25, the column 21 and the wing 23 are in the same plane, and a corresponding locking mechanism for limiting rotation is provided at the hinged joint to maintain the unfolded state. After the locking mechanism is released, the two columns 21 can be folded and rotated first, so that the column 21 and the wing 23 are at a 90-degree angle with the crossbar 25, and the enclosure 2 is in a U-shaped state. The two wings 23 are folded and rotated at 90 degrees, so that the wing 23 is close to the crossbar 25 and finally parallel to the crossbar 25, and the whole is a rectangular parallelepiped, which is convenient for storage.

[0240] The folding sequence may also be to fold the rotating wing 23 first and then fold the rotating column 21 .

[0241] The support legs 1 are fixedly arranged at the bottom of the column 21 , rotate along with the column 21 and are finally parallel to the cross piece 25 , and the two support legs 1 can be close to each other or overlap each other.

[0242] The bed guardrail of the present application is divided into three parts: a horizontal bar, a column and a wing. The support foot is connected to the bottom of the column. When folding, the support foot is parallel to the horizontal bar by rotating the column, and then the folding wing is rotated, and finally the whole is folded into a rectangular shape. The rotation and folding direction is consistent, and there is no need to operate the folding support foot or remove the support foot, which is convenient for folding. The support foot is fixedly connected to the lower part of the column, and the connection structure has higher strength.

[0243] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0244] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
