DETAILED DESCRIPTION

[0031] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0032] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0033] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0034] See also Figures 1 to 6In an embodiment of the utility model, a bed guardrail structure is installed on a bed frame 1, and the bed frame 1 is a hollow structure. The bed guardrail structure includes a guardrail body that penetrates the bed frame 1, and the guardrail body can slide in a vertical direction relative to the bed frame 1; a locking member is arranged on one side of the bed frame 1, and is used to fix the position of the guardrail body after the guardrail body moves to the end of the stroke relative to the bed frame 1. When the locking member is triggered to unlock, the guardrail body automatically moves downward under the action of gravity.

[0035] In this embodiment, by effectively combining the guardrail body with the bed frame 1, the stability of the guardrail body relative to the bed frame 1 can be effectively improved, eliminating the disadvantage of poor stability caused by the existing hinged storage. At the same time, the position of the guardrail body relative to the bed frame 1 can be fixed by the provided locking piece, and the guardrail body can be unlocked for storage when not in use, which is highly practical.

[0036] Furthermore, the guardrail body includes a plurality of vertical bars 3 and a horizontal bar 2 fixed to one end of the vertical bars 3, the vertical bars 3 are formed with limiting holes 302 adapted to the locking members, the bed frame 1 is formed with through grooves 101 for the vertical bars 3 to pass through, the vertical bars 3 are integrated with the bed frame 1, and the stability of the guardrail body can be effectively improved. Preferably, the vertical bars 3 are arranged in a rectangular structure, and the through grooves 101 are arranged in a rectangular structure, so as to ensure that the vertical bars 3 will not shake relative to the bed frame 1.

[0037] Preferably, an arcuate portion 301 is formed at one end of the vertical rail 3 away from the horizontal rail 2. When the vertical rail 3 moves downward to reach the storage state, the horizontal rail 2 fits onto the bed frame 1. The arcuate portion 301 makes the bottom of the vertical rail 3 tilt toward the inside of the bed bottom, thereby eliminating the space restriction on the footsteps of a person standing on the bed pan to a certain extent, and eliminating the situation where a person is tripped by the vertical rail 3 when walking.

[0038] In this embodiment, a gap is formed between two adjacent vertical rails 3. Even when the guardrail body is not in use, the user can place daily necessities toward the bottom of the bed through the gap to prevent interference caused by the guardrail body.

[0039] Furthermore, the locking member includes a movable frame 4 sliding on the bed frame 1, and a limiting unit adapted to the limiting hole 302 is installed on the side of the movable frame 4 facing the bed frame 1; an elastic reset member is arranged at one end of the movable frame 4 and connected to the bed frame 1; and a pin unit is arranged at the other end of the movable frame 4 and used to limit the movable frame 4.

[0040] In the locked state (that is, when the guardrail body is in use), one end of the movable frame 4 abuts against the latch unit, and the limiting unit is then inserted into the limiting hole 302 to fix the guardrail body, and the elastic reset member reserves elastic potential energy.

[0041] For an exemplary embodiment, please refer to Figure 3 and Figure 4 The limiting unit includes an embedded receiving plate 8 which is slidably mounted on the inner side of the bed frame 1 and fixed to the movable frame 4, and a limiting pin 9 which is engaged with the limiting hole 302 is fixed on the side of the embedded receiving plate 8 away from the movable frame 4, wherein the movable frame 4 and the embedded receiving plate 8 are fixed by a connecting frame, and a strip through groove 102 is formed on the bed frame 1, and the connecting frame passes through the strip through groove 102, so that the movable frame 4 and the embedded receiving plate 8 are respectively fitted with the inner and outer sides of the bed frame 1, and can slide relative to the bed frame 1, and the set limiting pin 9 is continuously stuck in the limiting hole 302 during the use of the guardrail body, so that the guardrail body will not slide relative to the bed frame 1, and preferably, the limiting hole 302 is arranged in a rectangular structure, and the limiting pin 9 is arranged in a rectangular parallelepiped structure.

[0042] For an exemplary embodiment, please refer to Figure 3 , Figure 5 and Figure 6 The elastic reset member includes a first fixing member 5 fixed to the bed frame 1, and a first embedded groove 501 is formed on the first fixing member 5; it also includes a movable column 12 fixed to the movable frame 4, the movable column 12 passes through the first fixing member 5 and extends into the first embedded groove 501, and a spring 11 is sleeved on the movable column 12 located in the first embedded groove 501, and the two ends of the spring 11 are respectively abutted against the inner wall of the first embedded groove 501 and the end of the movable column 12. Preferably, an extension disk is formed at the end of the movable column 12, and the spring 11 abuts against the extension disk.

[0043] In this embodiment, when the guardrail body is in use, since the movable frame 4 is in contact with the latch unit, a certain distance is created between the movable frame 4 and the first fixing member 5. That is to say, when the movable frame 4 moves toward the latch unit, the movable column 12 and the extension disk installed thereon are driven to move as a whole. At this time, the extension disk exerts an extrusion effect on the spring 11, so that the spring 11 reserves elastic potential energy, so as to drive the movable frame 4 to reset as a whole when the latch unit is out of the latching state.

[0044] For an exemplary embodiment, please refer to Figure 3 , Figure 5 and Figure 6The pin unit includes a second fixing member 6 fixed to the bed frame 1, the second fixing member 6 is formed with a second embedded groove 601, a clamping plate 10 fixed to the movable frame 4, the clamping plate 10 is formed with a clamping hole 1001, and also includes a pin 7 passing through the second fixing member 6. When the clamping plate 10 is inserted into the second embedded groove 601, the pin 7 can be clamped into the clamping hole 1001 to limit the movable frame 4, and at this time, the guardrail body is fixed relative to the bed frame 1.

[0045] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
