FIELD OF THE DISCLOSURE

The present disclosure relates to the field of furniture, in particular to a bed frame and its supporting structure.

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. Notably, a structure of middle support legs of the folding bed frames must enable foldable storage and provide stable support. The conventional middle support legs are generally connected to a middle folding structure of the folding bed frames. As a relatively concentrated support point of the folding bed frames, and due to the stability of the folding bed frames, automatic folding occurs easily at the middle support legs, especially in the middle folding structure. The automatic folding is often accompanied by damage to the middle support legs, which break under heavy pressure, thereby directly affecting the service life of the folding bed frames.

Referring to FIGS. 1 to 9, this embodiment provides a reinforcing structure for supporting a middle folding position of a bed frame. The reinforcing structure is mainly disposed on a supporting leg 2 on the middle folding position of the bed frame, and the reinforcing structure comprises an oblique supporting structure and a locking structure. The specific structure will be described as follows.

The bed frame comprises a bed frame body 1, two frames 11, and the supporting leg 2 connected to the middle folding position of the bed frame body 1. The two frames 11 of the bed frame are divided into a left frame 11a and a right frame 11b respectively disposed on two sides of the middle folding position of the bed frame body 1 in a left-and-right direction, and the left frame 11a and the right frame 11b are pivotally connected to a connecting piece 12. The connecting piece 12 comprises two hinge positions respectively connected to the left frame 11a and the right frame 11b. One of the left frame 11a or the right frame 11b can be rotated around the connecting piece 12 and folded relative to the other one of the left frame 11a or the right frame 11b, and the supporting leg 2 is fixedly connected to a middle position of the connecting piece 12. The two frames 11 are configured to be folded to drive the connecting piece 12 to rotate, so as to achieve a folding function of the supporting leg 2.

The reinforcing structure comprises a sliding sleeve 3 having the locking structure and one or more connecting rods 4 to define the oblique supporting structure for the two frames 11. The sliding sleeve 3 is slidably sleeved on the supporting leg 2. The sliding sleeve 3 is operatively coupled to a respective one of the two frames 11 through the one or more connecting rods 4. Two ends of the one or more connecting rods 4 are respectively and pivotally connected to the sliding sleeve 3 and the respective one of the two frames 11. The supporting leg 2 is configured to be in an unfolded state or a folded state relative to the respective one of the two frames 11 to enable the sliding sleeve 3 to move up and down along the supporting leg 2 in a length direction of the supporting leg 2. When in an unfolding process of the respective one of the two frames 11, the sliding sleeve 3 slides to enable the locking structure to be locked, the bed frame body 1 is in a fully unfolded state, and the supporting leg 2 is locked and maintained in the unfolded state. In the unfolded state, the respective one of the two frames 11, the one or more connecting rods 4, and the supporting leg 2 form a triangular supporting structure.

In this embodiment, the one or more connecting rods 4 are two connecting rods 4, the two connecting rods 4 are respectively and pivotally connected to the left frame 11a and the right frame 11b, and the two connecting rods 4 are riveted to the sliding sleeve 3. When the sliding sleeve 3 is in a locked state, the two frames 11, the two connecting rods 4, and the supporting leg 2 form a triangle supporting structure. The two connecting rods 4 are used as the oblique supporting structure and cooperate with the locking structure to enhance stability of a middle support of the bed frame, preventing the supporting leg 2 from automatically folding when one side of a bed board is pressed downward and the other side of the bed board tilts up. Using the two of the connecting rods 4 as the oblique supporting structure can increase supporting strength of a middle part of the bed frame body 1 and avoid collapse of the middle folding position of the bed frame due to insufficient support when the middle folding position of the bed frame is pressed.

In this embodiment, the locking structure comprises a locking core 21 disposed on the supporting leg 2, a locking hole 31 disposed on the sliding sleeve 3, and an unlocking button 32 disposed on the sliding sleeve 3 and configured to correspond to the locking hole 31. The locking core 21 has a certain amount of deformation to enable the locking core 21 to be locked or unlocked from the locking hole 31, and the sliding sleeve 3 slides to correspond to the locking hole 31 when in the unfolding process to enable the locking core 21 to be locked to the locking hole 31 to define a locking connection. The locking core 21 is retracted by the unlocking button 32 so as to be separated from the locking hole 31 to define an unlocking connection.

Specifically, the locking core 21 is a spring piece, which is V-shaped or U-shaped, having an elastic spherical head 22. After the sliding sleeve 3 slides to correspond to the locking hole 31 through one or more of the supporting legs 2 in the unfolded state, the elastic spherical head 22 pops up to block the locking hole 31 of the sliding sleeve 3 to form a locking fit to lock the sliding sleeve 3. The elastic spherical head 22 is pressed by pressing the unlocking button 32 to enable the elastic spherical head 22 to leave the locking hole 31 to achieve unlocking to enable the sliding sleeve 3 to slide, so as to achieve the folding and the unfolding of the supporting leg 2. At the same time, the bed frame body 1 can be stabilized in the unfolded state, and the support stability of the supporting leg 2 can be ensured when the supporting leg 2 is not unlocked.

This embodiment also provides the bed frame comprising the above-mentioned reinforcing structure, and the bed frame comprises the reinforcing structures respectively disposed on two of the supporting legs 2 located on two sides of the middle folding position of the bed frame body 1 in a front-and-rear direction. The two of the supporting legs 2 located on the two sides of the middle folding position of the bed frame are connected together through a lateral rod 5 serving as a stable connection structure for the two of the supporting legs 2, so that the two of the supporting legs 2 can be folded synchronously and the support stability of the two of the supporting legs 2 can be improved.

Specifically, the sliding sleeve 3 comprises a position-providing groove 33 for receiving the lateral rod 5. The position-providing groove 33 is a U-shaped groove. An opening of the U-shaped groove faces the lateral rod 5. When the bed frame body 1 is unfolded and the sliding sleeve 3 slides in place, the U-shaped groove receives the lateral rod 5 so as to enable the lateral rod 5 not to shake in the left-and-right direction and increase connection stability. At the same time, the sliding sleeve 3 is locked.

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.
