A connecting structure of a bed frame is disclosed. The bed frame includes a frame and bed legs connected under the frame. The frame includes two lateral rods and two longitudinal rods connected to the lateral rods. Respective two sides of the lateral rods or the longitudinal rods are provided with mounting troughs for insertion of respective two end portions of the longitudinal rods or the lateral rods. An outer side surface of each of the mounting troughs is provided with at least one mounting hole. The lateral rods and the longitudinal rods are perpendicularly connected to each other through the mounting troughs. The structure of the bed frame is simple, and the installation is convenient.

A reversible bed frame with a horizontal and an inclined position is disclosed herein. Its angular disposition is transformed from horizontal to inclined by turning it upside down. The bed frame preferably comprises multiple load-bearing elements (140) that are connected to and between two side rails (110) thus providing a top surface (150) and a bottom surface (210) of rectangular shape, with both surfaces able to withstand a load. Elevating members (120, 130) provide elevation for both surfaces. In accordance with one embodiment, the elevating members are of varying height so that the top surface is horizontal when facing upwards and the bottom surface is inclined when facing upwards. In accordance with another embodiment, different measurements and positioning of the load-bearing elements provide a horizontal top surface and an inclined bottom surface.

A bed frame convenient for changing bed sheets includes a base, a rotation module for accommodating a mattress located above the base, a sliding module located between the rotation module and the base, a sliding device located between the sliding module and the base, wherein the sliding module is able to slide along a length of the base through the sliding device, and a rotation device located between the sliding module and the rotation module, wherein the rotation module is able to rotate around a central axis of the sliding module. Through the cooperation of the sliding device and the rotation device, a staff is able to change the bed sheet only by standing in one position, which greatly saves energy and time of the staff. After changing the bed sheet every time, the mattress is rotated exactly 180 degrees, which is able to extend the life of the mattress.

An apparatus for upholstering a truss allows an operator to staple a fabric web to the truss, rotate the truss, further staple the semi-finished truss and cut the fabric web. The truss is fully upholstered after the end surfaces of the truss are wrapped up in fabric and the fabric stapled in place. The apparatus may accommodate different size trusses. A web of fabric is pulled around at least one roller in the apparatus by rotation of two vise mechanisms on opposite sides of the truss.

An adjustable bed frame includes first and second bed frame units. The first bed frame unit includes a first longitudinal rod, a second longitudinal rod, a first transverse rod, and a first vertical rod. The first longitudinal rod, the second longitudinal rod, and the first transverse rod are all pivotally attached to the first vertical rod. A locating hole passes through a side of the first transverse rod. The second bed frame unit includes a third longitudinal rod, a fourth longitudinal rod, a second transverse rod, and a second vertical rod. The third longitudinal rod, the fourth longitudinal rod, and the fourth transverse rod are all pivotally attached to the second vertical rod. A locating pin is disposed on a side of the second transverse rod. In an assembled state, the second transverse rod fits inside the first transverse rod, and the locating pin protrudes out through the locating hole.

A locking arrangement for assembly of a bed frame is provided. The locking arrangement comprises a first rail member comprising at least two first projecting interlocking holes and a second rail member comprising at least two sets of second projecting interlocking holes. The locking arrangement further comprises a set of pins such that, in assembled form of the bed frame, the first rail member and the second rail member are disposed in abutment with each other such that each of the at least two first projecting interlocking holes are received within one set of the at least two sets of second projecting interlocking holes to form a provisional locking structure, and each pin of the set of pins is engaged with one of the formed provisional locking structure by passing through the corresponding first projecting interlocking holes and second projecting interlocking holes thereof, to secure the first rail member and the second rail member.

A lower side bed frame of a double-layer iron frame bed comprises two transverse rods, two longitudinal rods, and four columns. An upper end of a lower column comprises a joint section formed by reducing a diameter. An upper column is sleeved on the joint section. An end surface of each of the two transverse rods is connected with a locking piece, and the locking piece abuts outer sides of the upper column and the lower column. An upper bolt enables the locking piece, the upper column, and the joint section to be locked together. A lower bolt enables the locking piece and the lower column to be locked together. Two supporting feet are located below a middle position of the two transverse rods. A connecting rod is connected between the two supporting feet and pulls the two supporting feet in a longitudinal direction.

Disclosed is an ultra-thin electric bed, including a front bed body and a rear bed body; the front bed body includes a front bed board; the rear bed body includes a rear bed board; a first spoke is disposed on a back of the front bed body, and a second spoke is disposed on a back of the rear bed body; two front longitudinal braces disposed are hinged to the first spoke, and a front cross brace is connected between the front longitudinal braces; two rear longitudinal braces disposed are hinged to the second spoke, and a rear cross brace is connected between the rear longitudinal braces; the two front longitudinal braces are disposed between the two rear longitudinal braces; and when the front bed body and the rear bed body are closed, the front cross brace is disposed between the rear cross brace and the rear crosspiece.

A back adjustable electrical bed frame comprises a head panel, a back panel, a buttocks panel, a thigh panel, a shank panel, a back pusher motor and a leg pusher motor. The leg pusher motor drives the buttocks panel through a scissor support assembly. The shank panel, parallel to the base, moves back and forth. The back panel has a back panel pivot at a quarter to a half of its lower part. The back panel is fixed to the base by a column having one end fixed to the base and the other end connected to the back panel pivot. The back pusher motor has a front end pivot connected with the back panel and a rear end pivot fixedly connected with the base. The front end pivot, the rear end pivot and the back panel pivot form a triangle to position an angle of the back panel.
