Description

Technical Field

[0001] The utility model relates to the technical field of electric beds, in particular to a bed frame with foldable bed legs. Background Art

[0002] Electric beds, with their adjustable positions to accommodate the user's body curves or sleeping position for optimal comfort, have become a common household item in modern homes. To facilitate user convenience and save packaging space during shipping, most electric bed frames are currently designed to be foldable. However, as accessories, the bed legs are often packaged separately and shipped with the bed frame. This often takes up packaging space, wastes packaging costs, and can easily lead to missed or incorrect shipments.

[0003] To this end, existing designs hinge the bed legs directly onto the bed frame. When stowed, the legs are folded onto the frame, and when in use, the legs are unfolded, with one end resting on the ground and the other end resting against the frame. However, this current technical solution lacks a retaining structure between the bed legs and the frame, making the bed legs unstable. When supported, they are prone to tilting, while when folded, they are unstable, causing them to swing during transportation and collide with other parts of the frame.

[0004] Therefore, a bed frame with foldable bed legs that is simple in structure, easy to operate, and stable in both folded and supported states needs to be designed. Utility Model Content

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

They do not indicate or imply that the devices or elements referred to must have a specific position, be constructed, or operate in a specific position. Therefore, they should not be construed as limiting the present invention. In addition, terms such as first and second are used only to distinguish multiple components or structures having the same or similar structures and do not represent any special limitation on the arrangement order or connection relationship.

[0043] Example 1

[0044] Please refer to Figures 1 to 10 The present invention provides a bed frame 100 with foldable legs, comprising a bed frame 1 and legs 2. Specifically, the bed frame 1 includes a base frame 11. As will be appreciated, the bed frame 1 also includes a back support frame 12, a hip support frame 13, and a leg support frame 14, disposed on the base frame 11. The legs 2 are pivotally mounted on at least four corners of the base frame 11 via a base frame fixing frame 3. A first elastic buckle 4 and a second elastic buckle 5 are disposed on the base frame 11. The base frame fixing frame 3 is provided with corresponding locking holes o. As will be appreciated, the first elastic buckle 4 and the second elastic buckle 5 are fasteners that retract when pressed and return to a protruding state when released. The legs 2 can be locked with the first elastic buckle 4 in a folded, stowed position through the locking holes o, or locked with the second elastic buckle 5 in an open, supported position through the locking holes o. As will be appreciated, the folded, stowed position of the legs 2 means that the legs 2 are approximately parallel to the base frame 11, i.e., they are stowed within the interior of the base frame 11. The bed legs 2 being in the open support state means that the bed legs 2 and the base frame 11 are in an intersecting state, that is, the bed legs 2 are in a working state of contacting the ground to support the bed frame 1 .

[0045] Alternatively, see Figure 5 、 Figure 7 and Figure 9In this embodiment, the first elastic buckle 4 is arranged horizontally with the rotation center of the bed foot 2, that is, the first elastic buckle 4 and the rotation center of the bed foot 2 are at the same horizontal height. The angle between the line connecting the first elastic buckle 4 and the rotation center of the bed foot 2 and the line connecting the second elastic buckle 5 and the rotation center of the bed foot 2 is equal to 90°. The distance between the first elastic buckle 4 and the rotation center of the bed foot 2 is equal to the distance between the second elastic buckle 5 and the rotation center of the bed foot 2. In this way, the bed foot 2 can be in a folded storage state when locked with the first elastic buckle 4 through the same lock hole o, and in an open support state when locked with the second elastic buckle 5. In this embodiment, the support leg provides vertical support force for the support base 11 when in working state. Of course, in other embodiments, the support leg can also provide tilted upward support force for the support base 11 when in working state. That is, the first elastic buckle 4 and the rotation center of the bed foot 2 are arranged horizontally; and the angle between the line connecting the first elastic buckle 4 and the rotation center of the bed foot 2 and the line connecting the second elastic buckle 5 and the rotation center of the bed foot 2 is greater than 90° and less than or equal to 120°, for example, 95°, 100°, 110° or 120°, as long as it is between 90° and 120°.

[0046] To further secure the bed leg 2 in its supported position, the lock hole o is optionally collinear with the extended axis of the bed leg 2 in this embodiment. This ensures that the rotation center of the bed leg 2, the lock hole o, and the extended axis of the bed leg 2 are aligned. Because the center of force is aligned, the bed leg 2 is not subject to off-center force components, thus further securing the bed leg 2 in its supported position.

[0047] Alternatively, see Figures 4 to 7 In this embodiment, the base frame 11 is formed by connecting a square longitudinal tube 111 and a square transverse tube 112. Specifically, the plurality of square longitudinal tubes 111 and square transverse tubes 112 can be connected together by welding or fasteners. At least the square transverse tubes 112 at the head and foot of the bed are vertically and side by side near the corners with a first mounting seat 113 and a second mounting seat 114. The foot fixing frame 3 is rotatably mounted on the first mounting seat 113, the first elastic buckle 4 is mounted on the second mounting seat 114, and the second elastic buckle 5 is mounted on the square transverse tube 112.

[0048] Alternatively, see Figure 7 and Figure 10In this embodiment, the second mounting seat 114 is a square tube seat, and the first elastic buckle 4 and the second elastic buckle 5 are both V-shaped spring buckles. The V-shaped spring buckle includes a head 41 and a V-shaped spring piece 42; the head 41 extends through the tube wall and can extend or retract; the V-shaped spring piece 42 is connected to the head 41, and its ends can correspondingly abut the inner walls of the tube. Thus, when the first elastic buckle 4 is configured on the second mounting seat 114, the ends of the V-shaped spring piece 42 of the V-shaped spring buckle correspondingly abut the inner walls of the second mounting seat 114, and the head 41 of the V-shaped spring buckle extends through the tube wall of the second mounting seat 114. Thus, when the head 41 of the first elastic buckle 4 is pressed, it retracts and compresses the V-shaped spring piece 42. When the bed foot 2 needs to be stored, the bed foot fixing frame 3 is rotated so that the lock hole o is aligned with the first elastic buckle 4. The V-shaped spring piece 42 of the first elastic buckle 4 is reset and pushes the head 41 to lock the lock hole o. The movement process and principle of the second elastic buckle 5 are the same as those of the first elastic buckle 4 and will not be described in detail here.

[0049] Alternatively, see Figure 7 In this embodiment, the bed foot bracket 3 is an L-shaped angle bracket. The vertical plate 31 of the bed foot bracket 3 is rotatably mounted on the first mounting base 113 via a hinge bolt shaft 6 and a locking nut 7. The bed foot 2 is supported by a suction cup detachably mounted on the horizontal plate 32 of the bed foot bracket 3. Optionally, the locking nut 7 is a self-locking nut that cooperates with the hinge bolt shaft 6.

[0050] Alternatively, see Figure 7 In this embodiment, a lubricating washer 8 is further disposed between the hinge bolt shaft 6 and the first mounting seat 113 and the foot fixing frame 3, and / or between the foot fixing frame 3 and the locking nut 7. Optionally, the lubricating washer 8 is made of nylon. This prevents direct frictional contact between the foot fixing frame 3 and the first mounting frame 113, and / or between the foot fixing frame 3 and the locking nut 7, during rotation and folding, which could damage the metal finish of the foot fixing frame 3 and / or the first mounting frame 113.

[0051] In order to reduce the packaging space of the bed frame 100 with foldable bed legs for easy transportation, optionally, please refer to Figure 2 and Figure 4 In this embodiment, the base frame 11 includes a first bed frame 15 and a second bed frame 16, which are rotatably connected. Optionally, the first bed frame 15 and the second bed frame 16 are rotatably connected via bolts. The first bed frame 15 and / or the second bed frame 16 are foldably provided with footrests 2 near the center of the bed frame 1 via footrest brackets 3, first elastic buckles 4, and second elastic buckles 5. This allows the addition of footrests 2 near the center of the bed frame 1 to distribute pressure around the four corners.

[0052] Example 2

[0053] This embodiment is essentially the same as the first embodiment, differing only in the assembly position of the bed legs 2, namely, near the head and foot of the bed, where the bed legs 2 are mounted on square longitudinal tubes 111. Specifically, in this embodiment, the base frame 11 is formed by connecting a square longitudinal tube 111 and a square transverse tube 112. A first mounting seat 113 and a second mounting seat 114 are vertically and juxtaposedly arranged on the square longitudinal tube 111, at least near the head and foot of the bed. The bed leg fixing frame 3 is rotatably mounted on the first mounting seat 113, the first elastic buckle 4 is mounted on the second mounting seat 114, and the second elastic buckle 5 is mounted on the square longitudinal tube 111.
