The following description, in conjunction with the accompanying drawings and preferred embodiments, is set forth as below to illustrate the present invention in detail. It is to be noted that spatial descriptions, such as “up,” “down,” “front,” “back,” “left,” “right,” “top,” “bottom,” “inside,” “outside” and so forth, are indicated with respect to the orientation shown in the figures unless otherwise specified. It should be understood that the spatial descriptions used herein are for purposes of illustration only, and that practical implementations of the structures described herein can be spatially arranged in any orientation or manner, provided that the merits of embodiments of this disclosure are not deviated by such arrangement.

Embodiment 1

As shown in FIG. 1, the present embodiment is a metal bedstead, which comprises a central strut 1, a plurality of bed slats 7, four corner legs 6, and front, back, left, and right rails 2, 3, 4, 5. The front, back, left, and right rails 2, 3, 4, 5 form a rectangular frame of the bedstead. The four corner legs 6 are located at the four corners of the rectangular frame. As shown in FIG. 6, each two adjacent rails and a corner leg 6 are in detachable connection through screws. As reflected in FIG. 6, the two corner legs 6 connected to the front rail 2 are provided with headboard connecting holes 601. There are three headboard connecting holes 601 arranged along the height of each of the corner legs 6, so as to enable height adjustment of the headboard and meet different user needs.

Two ends of the central strut 1 are in detachable connection with the front and back rails 2, 3, respectively, through second connectors 12. The bed slats 7 are arranged along and orthogonal to the central strut 1. Each of the bed slats 7 has one end in detachable fixation with the central strut 1 through a first connector 13, and has the other end in detachable fixation with the left rail 4 or the right rail 5 through a first connector 13.

As shown in FIG. 2 through FIG. 5, in the present embodiment, the central strut 1 and the rails are each composed of a bracket 8 that is of a U-like shape and rotating arms 9. There are two rotating arms 9, each of which is in rotatable connection with one end of the longitudinally extending lateral wall of the bracket 8 through a pivot pin. To assemble the bedstead, the rotating arms 9 are unfolded to from a long rod. When the bedstead is disassembled for transportation, the two rotating arms 9 are drawn close to each other so as to be compact and minimize the package volume. For enhancing the support strength of the metal bedstead, in the present embodiment, an intermediate leg 10 is fixed to the bracket 8 from below. In addition, the bracket 8 is formed with gaps 802 at two ends of its bottom wall. Provision of the gaps 802 allows the rotating arms 9 to be rotated for 90° toward the intermediate leg 10, so that the two rotating arms 9 can be both drawn toward the intermediate leg 10, thereby minimizing the package volume, facilitating transportation, and making the assembling/disassembling easy to consumers.

In order to further enhance the stability of the metal bedstead, as shown in FIG. 1, in the present embodiment, reinforcing braces 11 are provided between the intermediate legs 10 of the front and back rails 2, 3 and the rotating arms 9 of the central strut 1. The two ends of the reinforcing braces 11 are in detachable fixation and connection with the intermediate legs 10 of the rails and the rotating arms 9, respectively, through screws. Further, reinforcing braces 11 are provided between the intermediate legs 10 of the left and right rails 4, 5 and the bed slats 7. The two ends of the reinforcing braces 11 are in detachable fixation and connection with the intermediate legs 10 of the rails and the bed slats 7, respectively, through screws.

Referring to FIG. 2 through FIG. 5, the second connector 12 is of a reversed-L shape. The short leg of the second connector 12 is configured to press against the two rotating arms 9 to limit rotation of the rotating arms 9. The long leg of the second connector 12 has its front side for pressing against the lateral side of the bracket 8, and has its end in detachable connection with the intermediate leg 10 through screws. The long leg of the second connector 12 has its back side welded to the end of the bed slat 7 or the central strut 1. To further enhance connection strength between the second connector 12 and the central strut 1 or the rails, the short leg of the second connector 12 is formed with a waist hole 1201, and the bottom wall of the bracket 8 is formed with a threaded hole 801, while the two adjacent ends of the rotating arms 9 are each formed with a semicircular hole 901. As such, a screw 1202 can pass through the waist hole 1201 on the short leg of the second connector 12 and the circular hole formed by the two semicircular holes 901, and be screwed into the threaded hole 801 on the bottom wall of the bracket 8, thereby fixing the short leg of the second connector 12 to the bottom wall of the bracket 8, so that the short leg of the second connector 12 presses downward against the two rotating arms 9.

Referring to FIG. 7 through FIG. 9, the first connector 13 comprises a main part 1301 and an auxiliary part 1302. The main part 1301 is of a π-like shape, and is welded to the left rail 4 and/or the right rail 5 and/or the central strut 1, so that it works with the left rail 4 and/or the right rail 5 and/or the central strut 1 to form a socket therebetween. The auxiliary part 1302 has one end provided with an insert for being inserted into the socket, and has the other end welded to the end of the bed slat 7. The cooperation of the two parts of the first connector 13 enables insertion-and-withdrawal connection. Even if the bedstead uses many bed slats 7, consumers can perform assembly/disassembly rapidly and conveniently. Additionally, by properly designing the dimensions, firm and durable connection can be achieved and noise can be reduced. As compared to the prior-art products, the novel connection means of the present invention provides consumers with superior user experience.

Embodiment 2

The present embodiment is similar to Embodiment 1, except that the first connector 13 is shaped differently. As shown in FIG. 10 through FIG. 15, in the present embodiment, the first connector 13 similarly has a main part 1301 and an auxiliary part 1302. The main part 1301 is a socket directly formed on the left rail 4 and/or the right rail 5 and/or the central strut 1 through machining. The auxiliary part 1302 is an insert of a reversed-L shape. The insert has one end welded to the end of the bed slat 7, and has the other end for being inserted into the socket, thereby achieving insertion-and-withdrawal connection. To facilitate connection, as shown in FIG. 13 and FIG. 14, the socket of the main part 1301 on the rail is made by cutting the top and the lateral of the rail continuously so that the bed slat 7 can be easily inserted from above. The socket on the main part 1301 of the central strut 1 is made by cutting only the lateral of the central strut 1. During assembly, one end of the bed slat 7 is first inserted into the socket on the central strut 1, and then the other end is inserted into the socket on the rail.

Use of the first connectors 13 of Embodiment 2 allows consumers to perform the assembling/disassembling process conveniently and rapidly and makes the assembled product have attractive appearance while ensuring firm and durable connection.

The present invention has been described with reference to the preferred embodiments and it is understood that the embodiments are not intended to limit the scope of the present invention. Moreover, as the contents disclosed herein should be readily understood and can be implemented by a person skilled in the art, all equivalent changes or modifications which do not depart from the concept of the present invention should be encompassed by the appended claims.
