[0017] 3. Beneficial Effects

[0018] Compared with the prior art, the integrated, installation-free bed guardrail of the present invention can be used for both thick and thin mattresses, is more stable and firm than general bed guardrails on the market, and is easier to install. By folding various parts, the cloth cover can be packaged after installation in the factory. When using the bed, the customer only needs to place the pressure bar at the bottom of the bed, open the guardrail and install it on the bed body. The cloth cover can be pre-installed and can be directly unfolded and installed during assembly, which is especially convenient for some female users to use and assemble.

[0019] Specifically, the uprights and crossbars are connected by connectors to form a rectangular frame surrounding the mattress, and the crossbar installed at the bottom of the uprights is located on the top of the mattress to press and fix the mattress. Because the uprights and crossbars are vertically connected and form a rectangular frame, the guardrail has strong stability. When folding the crossbar, the button is pressed to move in the direction of the first spring. During the movement of the button, the button presses against the inclined surface of the insertion rod to squeeze the insertion rod. At this time, the insertion rod moves toward the inside of the second sleeve under the action of the inclined surface. After the insertion rod moves for a distance, the insertion rod slides out from the inside of the first sleeve. Then, the user holds the first sleeve and the second sleeve with both hands respectively, and then applies pressure to fold the crossbar. Similarly, during installation, pressure is applied to the first sleeve and the second sleeve to make the first rod part coaxial with the second rod part. After the first rod part and the second rod part are coaxial, the insertion rod is inserted into the first sleeve to be fixed.

[0020] The two adjacent cross bars at the top of the column of the present invention are fixedly connected by a first connecting piece, and the two adjacent cross bars at the bottom of the column are fixedly connected by a second connecting piece, and the connection between the ends of the two adjacent cross bars at the bottom of the column and the second connecting piece is a rotational connection, which can rotate, and the slide can be separated from the connecting sleeve by removing the block on the connecting sleeve, and then the slide can slide on the outer wall of the slide column, so that the cross bar at the top of the column can be separated from the connecting sleeve, and then the cross bar can be separated from the slide and folded, thereby further reducing the space occupied by the guardrail.

[0021] The present invention can also lock its length through the adjuster, so that the height of the guardrail can be controlled. When adjusting, the first rack and the second rack are first released by adjusting the movable block inside the second connecting member, and then the entire guardrail can be moved up and down. After the guardrail position is adjusted, the position of the movable block inside the second connecting member is restored to the original position so that the first rack and the second rack are again fixedly connected, so that the height of the guardrail can be accurately adjusted.

[0051] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0052] Embodiment 1:

[0053] like Figure 1 to Figure 14 As shown, a bed guardrail that does not require installation in this embodiment is applied to a bed with a mattress. The bed guardrail includes a support and a guardrail. The support is sandwiched between the bed and the mattress, and the guardrail is fixedly connected to the support. It is characterized in that the support is arranged at the head and tail ends of the bed, and the guardrail is foldable. When the guardrail is unfolded, it is combined with the support to form a whole surrounding the mattress.

[0054] Because the guardrail surrounds the entire mattress through the support, and the guardrail and the support are combined into a whole, the movement of the guardrail and the support relative to the mattress in any direction is restricted, so the guardrail will not move during use, and there will be no problems of misalignment or falling. In addition, the guardrail is foldable for easy installation by customers, and they only need to unfold the guardrail.

[0055] like Figure 1 and Figure 2 The guardrail includes a plurality of upright posts 1, a plurality of cross bars 2 and a connector 3; the upright posts 1 and the cross bars 2 are connected by the connector 3 and form a rectangular frame surrounding the mattress, and the support is connected to any one of the upright posts 1, the cross bars 2 and the connector 3; the cross bars 2 include a first rod portion 2a, a second rod portion 2b and a hinge 2c, the first rod portion 2a is hinged to the second rod portion 2b by the hinge 2c, and the guardrail is in an unfolded state when the first rod portion 2a and the second rod portion 2b are located on the same straight line.

[0056] During installation, the upright post 1 and the cross bar 2 are connected by the connecting piece 3 to form a rectangular frame surrounding the mattress, and the cross bar 2 installed at the bottom end of the upright post 1 is located on the top of the mattress to press and fix the mattress. Because the upright post 1 and the cross bar 2 are vertically connected to form a rectangular frame, the guardrail has strong stability.

[0057] Furthermore, in order to make the cross bar 2 foldable for storage and installation by customers, to solve this problem, as Figure 3 :

[0058] The hinged member 2c includes a first sleeve 2c1 and a second sleeve 2c2. One end of the first sleeve 2c1 is hinged to one end of the second sleeve 2c2. The first sleeve 2c1 is sleeved on one end of the first rod 2a, and the second sleeve 2c2 is sleeved on one end of the second rod 2b.

[0059] Based on the embodiment, the cross bar 2 is composed of a first rod portion 2a and a second rod portion 2b, and the first rod portion 2a is installed on the first sleeve 2c1 of the hinge 2c, and the second rod portion 2b is installed on the second sleeve 2c2 of the hinge 2c. When the guardrail needs to be folded, the first rod portion 2a and the second rod portion 2b can be folded up only by the hinge 2c, so that the space occupied by the guardrail is reduced and it is easy to install. Similarly, when the guardrail needs to be installed, the first rod portion 2a and the second rod portion 2b can be coaxial only by the hinge 2c to make the guardrail stable.

[0060] Further, in order to solve the problem of how to fold and install the cross bar 2, and how to ensure the stability of the cross bar 2 after installation, in order to solve this problem, Figure 4-7 :

[0061] The hinged member 2c also includes a button 2c3, an inclined surface 2c4, a first spring 2c5, an insertion rod 2c6 and a second spring 2c7; the button 2c3 is slidably connected to the first sleeve 2c2, and the sliding direction of the button 2c3 is perpendicular to the axis of the first sleeve 2c1; the first spring 2c5 is arranged inside the first sleeve 2c1, and the axis of the first spring 2c5 is parallel to the sliding direction of the button 2c3, and the two ends of the first spring 2c5 are respectively against the first sleeve 2c1 and the button 2c3; the insertion rod 2c6 is slidably arranged on the second sleeve 2c2, and the insertion rod The sliding direction of 2c6 is parallel to the axis of the second sleeve 2c2; the second spring 2c7 is arranged inside the second sleeve 2c2, the axis of the second spring 2c7 is coaxial with the axis of the second sleeve 2c2, and the two ends of the second spring 2c7 are respectively against the insertion rod 2c6 and the second rod part 2b; the button 2c3 is provided with a slope 2c4 near the insertion rod 2c6, and the slope 2c4 is against the insertion rod 2c6. When the button 2c3 moves toward the inside of the first sleeve 2c1, the insertion rod 2c6 moves toward the inside of the second sleeve 2c2 under the action of the slope 2c4.

[0062] When folding the cross bar 2, by pressing the button 2c3, move 2c5 in the direction of the first spring. During the movement of the button 2c3, the button 2c3 presses against the inclined surface 2c4 of the insertion rod 2c6 to squeeze the insertion rod 2c6. At this time, the insertion rod 2c6 moves toward the inside of the second sleeve 2c2 under the action of the inclined surface 2c4. After the insertion rod 2c6 moves for a distance, the insertion rod 2c6 slides out from the inside of the first sleeve 2c1. Then, the user holds the first sleeve 2c1 and the second sleeve 2c2 with both hands respectively, and then applies pressure to fold the cross bar 2. Similarly, during installation, pressure is applied to the first sleeve 2c1 and the second sleeve 2c2 to make the first rod portion 2a coaxial with the second rod portion 2b. After the first rod portion 2a and the second rod portion 2b are coaxial, the insertion rod 2c6 is inserted into the first sleeve 2c1 to be fixed.

[0063] Furthermore, in order to fix two adjacent cross bars in connection, to solve this problem, Figure 8 and Fig. 9 :

[0064] Two adjacent cross bars 2 located at the top of the column 1 are connected by a first connecting member 3a, and two adjacent cross bars 2 located at the bottom of the column 1 are installed on one side of the bottom end of the column 1 through a second connecting member 3b, and a sliding column 3c is connected between the first connecting member 3a and the second connecting member 3b.

[0065] Based on the embodiment, two adjacent cross bars at the top of the column 1 are fixedly connected by a first connecting member 3a, and two adjacent cross bars at the bottom of the column 1 are fixedly connected by a second connecting member 3b, and the connection between the ends of the two adjacent cross bars 2 at the bottom of the column 1 and the second connecting member 3b is a rotatable connection, which can rotate, thereby facilitating the folding of the guardrail and reducing the space occupied by the guardrail.

[0066] like Figure 2 and Fig. 9 The first connecting member 3a includes a connecting sleeve 3a1, and a slide 3a2 that can slide on the outer wall of the slide column 3c is horizontally installed at both ends of the connecting sleeve 3a1 through a clamping block, and the inner circumference of the slide 3a2 supports the cross bar 2.

[0067] Based on the embodiment, before the cross bar 2 needs to be folded, the slide 3a2 can be separated from the connecting sleeve 3a1 by removing the block on the connecting sleeve 3a1, and then the slide 3a2 can slide on the outer wall of the sliding column 3c, so that the cross bar 2 at the top of the column 1 can be separated from the connecting sleeve 3a1, and then the cross bar 2 can be separated from the slide 3a2 and the cross bar 2 can be folded, further reducing the space occupied by the guardrail.

[0068] Further, in order to fix the mattress, to solve this problem, Figure 3 :

[0069] The column 1 is installed with a connecting plate 4 through a second connecting member 3 b, and the connecting plate 4 is L-shaped. A horizontally arranged bed bottom pressure rod 5 is installed on the opposite side of the two connecting plates 4 .

[0070] Based on the embodiment, before the guardrail needs to be installed, the bed bottom pressure rod 5 is first placed and then the mattress is placed on top of the bed bottom pressure rod 5. Then, the unfolded guardrail is pressed and fixed to the bed bottom pressure rod 5 through the connecting plate 4. Then, the cross bar 2 at the bottom of the guardrail is pressed against the top of the mattress. The mattress is fixed by the cross bar 2 and the bed bottom pressure rod 5. The setting of the connecting plate 4 can prevent the bed bottom pressure rod 5 from moving, thereby improving the overall fixing firmness.

[0071] like Figure 3 and Fig.10 The outer wall of the bed bottom pressure rod 5 is connected with a fixer 6 by a buckle, and the fixer 6 includes a semi-arc clamping plate 6a1 buckled on the bed bottom pressure rod 5 and a first connecting plate 6a2 connected to one side of the semi-arc clamping plate 6a1, and the extended side of the first connecting plate 6a2 is fixedly connected with the second connecting plate 6a3, and the first connecting plate 6a2 and the second connecting plate 6a3 are connected in an arc shape.

[0072] Based on the embodiment, when placing the mattress, observe that one side of the mattress is in close contact with the fixing device 6, so that the mattress will not be misplaced or fall off after installation.

[0073] Embodiment 2:

[0074] Compared with Example 1, Figure 11 to Figure 13 As shown, in this embodiment, the connecting plate 4 and the column 1 are movably connected, and an adjuster 7 for adjusting the height of the column 1 is provided between the connecting plate 4 and the second connecting member 3b. The adjuster 7 includes an active clamping block 7a movably connected to the inner side of the second connecting member 3b. A first rack 7b is installed on the side of the connecting plate 4 facing the active clamping block 7a. The first rack 7b extends along the length direction of the connecting plate 4. A second rack 7c is connected to the side of the active clamping block 7a facing the connecting plate 4. The active clamping block 7a is in a clamping state when the second rack 7c abuts against the first rack 7b.

[0075] Based on the embodiment, the connecting plate 4 and the column 1 are combined into a retractable telescopic column, and then its length is locked by the adjuster 7, so that the height of the guardrail can be controlled. When adjusting, first adjust the active block 7a on the inner side of the second connecting member 3b to release the engagement between the first rack 7b and the second rack 7c, and then the entire guardrail can be moved up and down. After the guardrail position adjustment is completed, the position of the active block 7a on the inner side of the second connecting member 3b is restored to the position so that the first rack 7b and the second rack 7c are engaged and fixed again, so that the height of the guardrail can be accurately adjusted.

[0076] The outer circumference of the two columns near the fixer 6 also includes a horizontally arranged crossbar 2. In this embodiment, a group of crossbars 2 are arranged on the top of the columns 1 and connected to the top of the outer circumference of the two columns 1, making the guardrail more stable and not easy to be damaged.

[0077] Embodiment 3:

[0078] Compared with Example 1, Figures 15 to 21 As shown, the hinge 2c also has a second embodiment, the hinge 2c includes a third sleeve 2d1 and a fourth sleeve 2d4 whose ends are hinged to each other, the third sleeve 2d1 is sleeved on one end of the first rod portion 2a, and the fourth sleeve 2d4 is sleeved on one end of the second rod portion 2b; the third sleeve 2d1 is provided with an outwardly extending plug 2d2 at one end away from the first rod portion 2a, the fourth sleeve 2d4 is provided with an opening 2d5 for the plug 2d2 to be inserted, a spring pin 2d3 is embeddedly installed inside the plug 2d2, the actuator of the spring pin 2d3 extends out of the outside of the plug 2d2, the fourth sleeve 2d4 is provided with an opening 2d6 for the actuator of the spring pin 2d3 to be inserted, when the third sleeve 2d1 and the fourth sleeve 2d4 are located on the same straight line, the plug 2d2 is inserted into the opening 2d5, and the spring pin 2d3 is inserted into the opening 2d6.

[0079] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
