Detailed ways

Preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and understand the present invention, not to limit the present invention.

Embodiment 1 A length-adjustable bed frame

This embodiment adopts the detachable connection mode between the adjustment mechanism and the bed frame 1, so that the adjustment mechanism is fixed at different positions of the bed frame 1 to initially adjust the use length of the bed frame 1, and then combined with the fixed plate 3 and the connecting plate 2 in the adjustment mechanism. The position of the bedstead 1 is changed to further extend the use length of the bedstead 1 , and the use length of the bedstead 1 can be further extended by using the sleeve 5 to extend the length. The use length of the bed frame 1 referred to in this application means that after the adjustment mechanism is provided on the bed frame 1, the adjustment mechanism extends the originally fixed length of the bed frame 1, that is, the length that the bed frame 1 and the adjustment mechanism can be used by the user.

As shown in Figures 1 to 7, this embodiment includes a bed frame 1 and an adjustment mechanism.

1. Bed frame 1

The bed frame 1 is a frame of a bed extending longitudinally and laterally, and the bed frame 1 is used for placing a mattress. In the present embodiment, the bedstead 1 is a rectangular frame, and the length of the bedstead 1 is greater than the width of the bedstead 1 . The bed frame 1 has four bed corners, the head of the bed frame 1 is a headboard area, and a headboard can be installed in the headboard area;

An adjustment mechanism is detachably connected to the bed frame 1, and the adjustment mechanism is located at each corner of the bed frame 1 at the head and/or end of the bed. That is to say, the position of the adjustment mechanism has the following three options: the adjustment mechanism is set on the two bed corners at the head of the bed, and the adjustment mechanism is not set on the two bed corners at the end of the bed, refer to Figure 1 and Figure 2; Adjustment mechanisms are set on the two corners of the bed, but no adjustment mechanism is set on the two corners of the head of the bed, refer to Figure 3 and Figure 4; adjustment mechanisms are set on all the corners of the head and end of the bed, refer to Figure 5 with Figure 6.

2. Regulating mechanism

The adjustment mechanism includes a fixed plate 3 , a connecting plate 2 , a connecting piece and a sleeve 5 .

(1) Connecting plate 2 and fixing plate 3

The adjustment mechanism includes a connecting plate 2 and a fixed plate 3 that are integrally fixed and connected. Both the connecting plate 2 and the fixing plate 3 are in the shape of a square plate. The angle formed between the connecting plate 2 and the fixing plate 3 is α, which satisfies α∈(0 ,180°), that is to say, the angle formed between the connecting plate 2 and the fixing plate 3 is any one of an acute angle, a right angle or an obtuse angle. In order to make the connection more stable, preferably, the angle between the connecting plate 2 and the fixing plate 3 is a right angle.

The connecting plate 2 is provided with a connecting piece detachably connected with the bed frame 1 so that the connecting plate 2 is fixed on the bed frame 1 . The fixing plate 3 is fixed with a connecting nail 6 extending to the outside of the bed frame 1 along the width direction of the bed frame 1, and is clamped in the clamping groove on the headboard or the footboard by the connecting nail 6, so that the headboard or the footboard The board is fixed on the bed frame 1, and the clamping form of the connecting nail 6 and the headboard or the tailboard belongs to the prior art.

Regarding the connection position of the connecting plate 2 and the fixing plate 3 relative to the bed frame 1, there are the following options:

(1) In the projection of the horizontal plane, auxiliary lines are added so that the fixed plate 3 and the connecting plate 2 are connected end to end by a straight line to form a closed figure, and the formed closed figure intersects with the projection of the bed frame 1.

The projection on the horizontal plane referred to here refers to the top view of the bed frame 1 and the adjustment mechanism. In other words, it is the projection of the bed frame 1 and the adjustment mechanism on the horizontal ground. Figures 2 to 6 are the bed frame 1 and the adjustment mechanism on the horizontal plane. projection view.

Since the fixed plate 3 and the connecting plate 2 are plate-shaped with two ends connected, the projection of the two on the horizontal plane is "L" shape (when the angle between the fixed plate 3 and the connecting plate 2 is a right angle) or "∠" shape (fixed When the angle between the plate 3 and the connecting plate 2 is an acute angle) or the open figure of "factory" shape (when the angle between the fixed plate 3 and the connecting plate 2 is an obtuse angle). An auxiliary line is added in the formed horizontal plane projection, so that the fixed plate 3 and the connecting plate 2 are connected head to tail by a straight line to form a right triangle, an acute triangle or an obtuse triangle, and the formed triangle is a closed figure. Referring to Fig. 3 and Fig. 6, the connecting plate 2 and the fixing plate 3 are projected into an "L" shape, and the dotted lines added in the figure are auxiliary lines, finally forming a right triangle.

The condition that needs to be met is: after adding the auxiliary line in the projection of the horizontal plane, the closed figure formed by the fixed plate 3 and the connecting plate 2 intersects with the projection of the bed frame 1 . In other words, the bed frame 1 is placed in the angle formed by the fixing plate 3 and the connecting plate 2 . In this embodiment, when the angle between the connecting plate 2 and the fixed plate 3 is a right angle, the connecting plate 2 extends along the length direction of the bed frame 1, the fixed plate 3 extends along the width direction of the bed frame 1, and the connecting plate 2 and the fixed plate 3 They are respectively in contact with the two sides of the corner of the bed, and the connecting plate 2 and the fixing plate 3 are covered outside the corner of the bed.

(2) In the projection to the vertical plane where the length direction of the bed frame 1 is located, the projected area of the fixing plate 3 intersects with the extension line where the length of the bed frame 1 is located.

The bedstead 1 in this embodiment is a cuboid frame, and the vertical plane where the lengthwise direction of the bedstead 1 is referred to here is equivalent to the side where the lengthwise direction is located on the bedstead 1 . Regardless of whether the angle between the fixed plate 3 and the connecting plate 2 is an acute angle, a right angle or an obtuse angle, in the projection of the fixed plate 3 on the vertical plane where the length direction of the bed frame 1 is located, the projection of the fixed plate 3 is a square, while the projection of the fixed plate 3 The area intersects with the extension line where the length of the bed frame 1 is located.

It should be noted that the length of the bed frame 1 referred to in the present application is not the use length after the length of the bed frame 1 is adjusted by using the adjustment mechanism, but the original fixed length of the bed frame 1 or the bed frame 1 itself. Word. Shown with reference to Fig. 7, dotted line among the figure represents the extension line of bedstead 1 length. In this embodiment, when the angle between the connecting plate 2 and the fixing plate 3 is a right angle, the projected area of the fixing plate 3 intersects the extension line of the length of the bed frame 1 .

(2) Connectors, sleeves 5

In order to be easy to connect and disassemble, bolts 4 and nuts are selected for the connectors connecting the bed frame 1 and the connecting plate 2. And for further prolonging the length of bed frame 1 after using adjustment mechanism, sleeve 5 is set between connecting plate 2 and bed frame 1, and sleeve 5 extends along the length direction of bed frame 1, and sleeve 5 is sleeved on bolt. 4 outside, make bolt 4 to be fixedly connected with the nut on the bed frame 1 by screw thread again. Reference may be made to the sleeve 5 provided in FIGS. 3 to 5 .

The method for adjusting the use length of the bedstead 1 using this embodiment can refer to the description in Embodiment 2.
