Folding mechanism and folding mattress support frame

Abstract

The invention discloses a folding mechanism used for folding a foldable mattress supporting frame. The foldable mattress supporting frame comprises a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod, wherein the first connecting rod and the second connecting rod are connected in a butt joint mode, and the third connecting rod and the fourth connecting rod are connected in a butt joint mode. The folding mechanism comprises a pivot joint piece, a first pivot joint arm and a second pivot joint arm. The pivot joint piece is connected with the free ends of the first connecting rod and the second connecting rod in a pivot joint mode, the first connecting rod and the second connecting rod are in butt joint in a pivot joint mode through the pivot joint piece, the first pivot joint arm is further fixedly connected with the third connecting rod, the second pivot joint arm is fixedly connected with the fourth connecting rod, the upper ends of the first pivot joint arm and the second pivot joint arm are connected with the lower side of the pivot joint piece in a pivot joint mode, the third connecting rod and the fourth connecting rod are in butt joint in a pivot joint mode through pivot joint between the first pivot joint arm, the second pivot joint arm and the pivot joint piece, the pivot joint piece forms a non-linear three-point pivot joint structure, and folding can be achieved by applying force to rotate any connecting rod. The invention further discloses the foldable mattress supporting frame with the folding mechanism. After being folded, the foldable mattress supporting frame is regular in outline, small in size and convenient to package, carry and transport.

Description

technical field [0001] The invention relates to a furniture article, in particular to a foldable mattress supporting frame for supporting a mattress and a folding mechanism used for performing the folding function. Background technique [0002] In the prior art, there are usually the following two placement methods for sleeping mattresses: [0003] A method used by Asians who are relatively short in height. This method is to directly lay the mattress on the bed frame. In order to reflect the comfort, luxury and aesthetics of the bed frame, the frame of the bed frame is usually made of It is made of solid wood, and then decorated with various colors. At the same time, in order to facilitate the bearing of the mattress, a number of horizontal bars are arranged horizontally and parallel on the frame. When the mattress is smaller than the frame, the mattress can be directly carried on the horizontal bars; even When the mattress is larger than the frame, when the mattress can be...

Problems solved by technology

In order to ensure the integrity, firmness and aesthetics of the bed frame, the frame of the existing bed frame cannot be folded, because its size (usually standard: 1.8m×1.8m, 2.0m×2.0m) is too large, so Extremely inconvenient during packing, handling and transportation

[0004] Another method is used by Europeans and Americans who are relatively tall. This method has one more mattress support frame than the above method. When using it, first place the mattress support frame on the bed frame, and then lay the mattress On the mattress supporting frame, due to the mattress supporting frame, the height of the mattress can be increased, which is more suitable for use by Europeans and Americans who are relatively tall. Since the height of the legs of the bed frame has not changed, so It is also suitable for Europeans and Americans without any reinforcement design and improvement of the bed frame. Most of the existing mattress support frames cannot be folded, so there are also defects that are extremely inconvenient for packaging, handling and transportation; a small part can be folded, However, its structure is relatively complicated, and its shape is irregular and bulky after folding, which is also inconvenient for packaging, handling and transportation.
