FIELD OF THE DISCLOSURE

The present disclosure relates to the field of furniture, and in particular to bed frames and bed legs for furniture.

BACKGROUND OF THE DISCLOSURE

Beds are very common in our daily lives and are indispensable furniture. There are two commonly used bed frames, one is foldable and the other is non-foldable. With the improvement of living standards, the demand for furniture products has also shown a diversified trend. Folding bed frames have become a mainstream in the bed frame market due to their foldable storage properties.

Due to its foldable design, the folding bed frames are less stable than non-foldable bed frames. In order to facilitate disassembly, each support connection of the folding bed frames mainly adopts a hinged structure. A structure of bed legs of the folding bed frames must enable foldable storage and provide stable support. One type of bed frame comprises a bed frame body and bed legs detachably connected to the bed frame body, and the bed legs are fastened to the bed frame body using screws or pins. This structure has stability, but the structure is inconvenient to disassemble. Accessories are easy to misplace and lose, which is not conducive to transport. Another type of bed frame comprises a bed frame body and foldable bed legs that fold relative the bed frame body. This structure has flexibility due to the folding of the foldable bed legs, but this structure is not sufficiently stable and unexpected folding of the bed legs can occur due to the bed frame body shaking, resulting in a collapse of the bed frame body. To provide additional stability to the foldable bed legs, a complex locking structure is provided at an articulated end of the foldable bed legs. Because the foldable bed legs support the bed frame body, compressional deformation of the foldable bed legs and their connecting joints occurs over time, and the locking structure will be squeezed to be unable to be unlocked, resulting in the bed legs losing their folding function.

BRIEF SUMMARY OF THE DISCLOSURE

The main technical problem to be solved by the present disclosure is to provide a folding structure for one or more bed legs of a bed frame and a bed frame, which can ensure the convenience of folding the one or more bed legs, and at the same time, can increase bed leg support stability.

In order to solve the technical problem, a first technical solution of the present disclosure is as follows.

Compared with the existing techniques, the technical solution has the following advantages.

• • 1. The present disclosure provides the one or more locking devices and the one or more connecting rods on the folding structure for the one or more bed legs. When the one or more bed legs are unfolded, a triangular supporting structure is formed by the one or more connecting rods and the supporting rod to further stabilize a support structure of the one or more bed legs. To a certain extent, when in the use, an unexpected folding state of the one or more bed legs is avoided. The one or more locking devices enable the one or more bed legs to be locked in the unfolded state to stabilize the support structure of the one or more bed legs.
  • 2. The present disclosure adopts the one or more locking devices on the frame, and the one or more locking devices are not connected to an articulated end (i.e., the articulated end is a supporting end) of the one or more bed legs. The one or more locking devices in a bed frame do not need to bear a pressure of a whole bed frame, so as to avoid the one or more locking devices being unable to be unlocked due to compression and to ensure that a folding function of the bed leg can be maintained.
  • 3. The one or more locking devices of the present disclosure have a simple structure and are easy to operate, with unfolding of the one or more bed legs and cooperation of the spring to realize automatic locking of the one or more locking devices. A stable triangular support is formed by the one or more connecting rods. When unlocking, a first one of the one or more locking devices on one side of the bed frame is operated to cooperate with the linking rod to unlock a second one of the one or more locking devices on the other side of the bed frame. The unlocking operation of the two locking devices on opposite sides can be performed at the same time, and the folding and storing is simple and convenient.

Referring to FIGS. 1-9, the present embodiment provides a folding structure for a bed leg 12 of a bed frame, and the folding structure comprises a bed frame body 1, a frame, and the bed leg 12, of which a first end of the bed leg 12 is pivotally connected to the frame. The frame comprises a supporting rod 11 pivotally connected to the bed leg 12 and sleeved with a sliding seat 2, and a connecting rod 3 is pivotally connected to the sliding seat 2 and the bed leg 12. The supporting rod 11 of the frame, the connecting rod 3, and the bed leg 12 form a triangular supporting structure, and the sliding seat 2 has a certain amount of displacement along a length direction of the supporting rod 11 of the frame.

During a folding process of the bed leg 12, the bed leg 12 is rotatable relative to the frame using an articulated end relative to the frame to be adjacent to or separated away from the frame to realize the folding process. During a rotation of the bed leg 12, the connecting rod 3 pivotally connected to the bed leg 12 generates a certain pushing force applied to the sliding seat 2 with the rotation of the bed leg 12 to realize an amount of sliding of the sliding seat 2 on the supporting rod 11 of the frame.

For fastening the bed leg 12 in an unfolded state, a locking device 4 is disposed on the supporting rod 11 of the frame, and the locking device 4 is disposed at a rear end of a sliding direction of the sliding seat 2 during an unfolding process of the bed leg 12. A location of the locking device 4 corresponds to a location of the sliding seat 2 at which the bed leg 12 is unfolded to provide support to enable the sliding seat 2 to be locked on the locking device 4 to form a locking fixation. The bed leg 12 is enabled to be maintained in the unfolded state through locking between the locking device 4 and the sliding seat 2 and supporting of the bed leg 12 and the connecting rod 3.

When the bed leg 12 is unfolded to use, the connecting rod 3 and the frame form the triangular supporting structure, further stabilizing the bed leg 12, avoiding an abnormal folding phenomenon during use, and affecting the overall use of the bed frame. Furthermore, the bed leg 12 is enabled to be locked in the unfolded state using the locking device 4 to stabilize the bed leg 12 and reduce shaking of the bed frame during use, which prevents the bed leg 12 from an unexpected folding situation due to the bed leg 12 not being reliably locked when the bed frame is shaking.

In this embodiment, the locking device 4 is disposed on the supporting rod 11 of the frame and provides support between the connecting rod 3 and the bed leg 12. The locking device 4 does not need to provide support for the bed frame while support of the bed frame is on the bed leg 12. The locking device 4 is not subject to excessive pressure during use, which can guarantee normal use of the locking device 4, avoid the locking device 4 from being stuck, and ensure that the folding structure of the bed leg 12 can be used normally.

In this embodiment, the locking device 4 comprises a U-shaped seat 41 having an opening 411, a snap portion 42 facing the sliding seat 2 and disposed on the U-shaped seat 41, and a snap member 21 disposed on the sliding seat 2. The U-shaped seat 41 is pivotally connected to the supporting rod 11 of the frame using the opening 411, and a pivoting end of the U-shaped seat 41 is a rivet. A gap between the opening 411 and the supporting rod 11 of the frame is provided. The snap portion 42 is disposed at an end of the U-shaped seat 41 facing the sliding seat 2, and a lower end surface of the snap portion 42 is flush with a lower end surface of the U-shaped seat 41. A height of the snap portion 42 is matched with the gap.

Specifically, the snap portion 42 comprises a U-shaped groove 421, and an opening of the U-shaped groove 421 faces toward the supporting rod 11 of the frame. When an end surface of the snap portion 42 abuts an end surface of the supporting rod 11 of the frame, the U-shaped groove 421 forms a locking chamber 423 for a snap locking engagement with the snap member 21 of the sliding seat 2.

Locking between the snap portion 42 and the snap member 21 of the sliding seat 2 will be described as follow. A spring 43 having elastic deformation is disposed in the gap between the U-shaped seat 41 and the supporting rod 11 of the frame, and the spring 43 and the snap portion 42 are respectively located on two opposite ends of the U-shaped seat 41. The U-shaped seat 41 can have a certain amount of rotation about the pivoting end of the U-shaped seat 41 that is used as an axle. When a first end of the U-shaped seat 41 disposed with the spring 43 is moved upward or downward, the U-shaped seat 41 can be rotated about the hinged end, a second end of the U-shaped seat 41 having the snap portion 42 is simultaneously moved downward or upward using the pivoting end as a pivot, so that the snap portion 42 is correspondingly adjacent to or separated from the supporting rod 11 of the frame to enable the locking chamber 423 to be open to form or terminate the snap locking engagement with the snap member 21 or enable the locking chamber 423 to be closed to form a position inhibition between the snap portion 42 and the snap member 21 (i.e., the snap portion 42 is locked to the snap member 21).

In this embodiment, the spring 43 is used as a locking driving member, and in an initial position, due to an elastic force of the spring 43, the second end of the U-shaped seat 41 abuts the end surface of the supporting rod 11 of the frame, so that the snap portion 42 is adjacent to the supporting rod 11 of the frame to form the locking chamber 423, which is closed. In the initial position, in order to realize automatic locking of the snap portion 42 to the sliding seat 2, the snap portion 42 comprises the U-shaped groove 421 and a guiding-in slope 422, and guiding-in slope 422 is defined by the end surface of the snap portion 42 inclining toward the U-shaped groove 421. When the bed leg 12 is unfolded, the sliding seat 2 slides toward the U-shaped seat 41, and the snap member 21 abuts the guiding-in slope 422 to be further moved along the guiding-in slope 422 to press the second end of the U-shaped seat 41 downward, so as to make the snap portion 42 rotate downward around a pivoting portion 412 (i.e., the pivoting end) to enable the snap member 21 to be snapped into the U-shaped groove 421. While the snap member 21 is snapped into the U-shaped groove 421, the elastic force of the spring 43 drives the snap portion 42 to rotate upward around the pivoting portion 412 to be reset to the initial position, and the snap member 21 in the U-shaped groove 421 and the supporting rod 11 are enabled to form a position inhibiting connection, thus completing an automatic locking.

When the bed leg 12 is unfolded to be used as a support, a force given to the sliding seat 2 by the bed leg 12 through the connecting rod 3 is along the length direction of the supporting rod 11, and the U-shaped groove 421 is buckled to the snap member 21, which inhibits the sliding seat 2 from sliding along the length direction of the supporting rod 11, thus realizing locking of the bed leg 12 to be in the unfolded state. When the bed leg 12 is locked, the first end of the U-shaped seat 41 is driven by a downward elastic force of the spring 43 to enable the snap portion 42 to be consistently tilted upward to cooperate with the supporting rod 11 to enable the snap member 21 to be maintained in the U-shaped groove 421, thus realizing a long-term locked state. When the bed leg 12 needs to be folded, it is only necessary to press down the first end of the U-shaped seat 41 that is disposed with the spring 43, and the first end of the U-shaped seat 41 is pressed upward to be adjacent to the supporting rod 11. At this time, the second end of the U-shaped seat 41 that defines the snap portion 42 is rotated downward and separated away from the supporting rod 11, the snap member 21 is released from the position inhibiting connection, and the sliding seat 2 can slide away from the U-shaped seat 41, so that folding and storage of the bed leg 12 can be realized.

In this embodiment, the sliding seat 2 comprises a U-shaped sliding groove 22, and the U-shaped sliding groove 22 is sleeved on the supporting rod 11 using a connecting member to realize assembly of the sliding seat 2. The connecting member is a first rivet, and the connecting member is the snap member 21. When in an assembly process, two sides of the U-shaped sliding groove 22 are respectively sleeved on an outer side of the supporting rod 11, and the first rivet passes through the two sides of the U-shaped sliding groove 22. A portion of the first rivet located in a spaced opening of the U-shaped sliding groove 22 is placed on a bottom end surface of the supporting rod 11 in a sliding connection, and the sliding seat 2 is enabled to slide on the supporting rod 11.

The U-shaped seat 41 is connected to the supporting rod 11 through the opening 411 by a second rivet, the opening 411 is U-shaped, and the second rivet for the U-shaped seat 41 penetrates through the supporting rod 11 to realize fixation of the U-shaped seat 41 to a fixed position of the supporting rod 11. The second end of the U-shaped seat 41 disposed with the snap portion 42 comprises a diameter-reduced section 44 connected to the snap portion 42. A minimum width of the diameter-reduced section 44 is matched with a width of the supporting rod 11, and the snap portion 42 is matched with the minimum width, so that when the sliding seat 2 slides to perform the position inhibiting connection with the U-shaped seat 41, a width of the snap portion 42 is matched with a width of the U-shaped sliding groove 22 of the sliding seat 2, and the snap portion 42 can be locked to the first rivet in the U-shaped sliding groove 22.

The folding structure for the bed leg 12 in this embodiment is mainly applied to a bed frame, and two of the bed legs 12 are respectively disposed on two sides of frame, especially being respectively disposed on two sides of a short side frame of the frame to form a four-legged support structure. The bed legs 12 are disposed on an end of a long side frame of the frame adjacent to the short side frame. The bed legs 12 are unfolded to be locked through the folding structure provided in this embodiment, which is convenient and safe.

When performing unlocking and folding of the two of the bed legs 12, the present embodiment adopts a linking rod 5 between two of the locking devices 4 respectively disposed on the two sides of the short side frame of the frame and correspond to the two of the bed legs 12, so as to realize a synchronized unlocking operation of the two of the locking devices 4 through the linking rod 5.

Specifically, a rod used as the linking rod 5 is fixedly connected between two of the U-shaped seats 41 on the two sides of the short side frame. In this embodiment, two ends of the rod are fixedly connected to the pivoting portions 412 of the two of the U-shaped seats 41. When one of the two of the U-shaped seats 41 is rotated around a corresponding one of the pivoting portions 412, a rotation of an end surface of the corresponding one of the pivoting portions 412 drives the rod fixedly connected thereon to rotate around an axis of the rod, thereby driving a rotation of the other one of the two of the U-shaped seats 41 to realize a linkage unlocking operation.

At the same time, the rod is configured to support ribs 13 defining a support surface of the bed frame body 1 to further stabilize stiffness of the ribs 13 in a state of use. When the snap portion 42 rotates to a locked state, the linking rod 5 supports the ribs 13 defining the support surface of the bed frame body 1 to further stabilize the ribs 13, to reduce a risk of local fracture of the ribs 13, and to increase a safety performance of the bed frame in a process of use.

The aforementioned embodiments are merely some embodiments of the present disclosure, and the scope of the disclosure is not limited thereto. Thus, it is intended that the present disclosure cover any modifications and variations of the presently presented embodiments provided they are made without departing from the appended claims and the specification of the present disclosure.
