Description

Technical Field

[0001] This application relates to the field of nap beds, and more particularly to a foldable bed frame and a nap bed. Background Technology

[0002] Nap beds, also known as afternoon nap beds, are mostly foldable. Compared to traditional beds, nap beds are smaller in size and can be folded up when not in use, making them popular among office workers and often used as sleeping furniture during lunch breaks.

[0003] Existing nap beds mainly consist of a foldable bed frame and a bed surface on the frame. When unfolded, the bed surface is rectangular. However, this type of rectangular nap bed still has shortcomings in practical use. For example, when unfolded, this type of nap bed takes up a large amount of space, making it difficult to unfold and use in some small spaces, especially in places where there is little space at the head and foot. Therefore, it needs to be improved. Utility Model Content

[0004] In order to solve at least one of the technical problems mentioned in the background art, the purpose of this application is to provide a foldable bed frame and a nap bed.

[0005] To achieve the above objectives, this application provides the following technical solution.

[0006] On one hand, this application provides a foldable bed frame for installing the surface of a nap bed, the bed frame being switchable between a folded state and an unfolded state, the bed frame comprising:

[0007] Two side frames are arranged opposite each other along a first direction to support the bed surface. Each side frame includes a first support and two second supports located on either side of the first support. The first support is telescopically foldable along a second direction, which is perpendicular to the first direction. In the unfolded state: the tops of the two opposing first supports along the first direction enclose a first support area for supporting the middle region of the bed surface; the tops of the two opposing second supports along the first direction enclose a second support area for supporting the end region of the bed surface. In the same side frame, the second supports are inclined relative to the first supports at an angle A, so that the width of the second support area in the first direction gradually narrows in the second direction away from the first support. The second supports are telescopically foldable along their inclined direction relative to the first support.

[0008] A support frame is provided between the two side frames to support the two side frames in the first direction.

[0015] As an optional embodiment of this application, a first top hinge seat is fixed to the top of the first column; the first ends of the two top rods are respectively hinged to the first top hinge seat.

[0016] As an optional embodiment of this application, the upper end of the first rod is hinged to a first hinge seat, and the lower end of the first rod is hinged to a second hinge seat. The hinge axes of the first rod, the first hinge seat, and the second hinge seat are all parallel to a first direction. The second end of the first top rod is hinged to the first hinge seat around a hinge axis parallel to the first direction. The second bracket includes:

[0017] The second crossbar includes two second rods hinged at their middle portions to a second hinge point, the hinge axis of the second hinge point being perpendicular to the inclined direction; of the two second rods adjacent to the end of the first crossbar, the upper one is hinged to a first hinge seat, and the lower one is hinged to a second hinge seat; the hinge axes of the second rods to the first hinge seat and the second hinge seat are both perpendicular to the inclined direction.

[0018] The second column is provided with a second sliding sleeve that can slide relative to the second column along the axis of the second column; the second hinge point is located on the second sliding sleeve.

[0019] Two second push rods are provided, with the top of each push rod hinged to the top of the second column around a hinge axis perpendicular to the inclined direction. In the unfolded state, the two second push rods extend along the inclined direction to unfold on both sides of the top of the second column.

[0020] As an optional embodiment of this application, the support frame includes a third crossbar disposed between the two side frames; the third crossbar includes two third rods hinged together at their middle parts, and the hinge axes of the two third rods are parallel to the second direction; among the ends of the two third rods adjacent to the side frames, the one on the upper side is hinged to the first hinge seat, and the one on the lower side is hinged to the second hinge seat, wherein the hinge axes of the third rods with the first hinge seat and the second hinge seat are both parallel to the second direction.

[0021] As an optional embodiment of this application, the support frame includes two scissor links disposed between the two end sides of the side frame, which are telescopic in a vertical and a first direction; the scissor links are located at the two ends adjacent to the side frame, with the upper one hinged to a third hinge seat about a hinge axis parallel to the second direction, and the lower one hinged to a fourth hinge seat about a hinge axis parallel to the second direction; at the two ends of the two second rods away from the first support, the upper one is hinged to the third hinge seat, and the lower one is hinged to the fourth hinge seat, and the hinge axis of the second rods and the third and fourth hinge seats is perpendicular to the tilt direction.

[0022] As an optional embodiment of this application, the first column is provided with a first limiting protrusion, which is located below the first sliding sleeve to limit the downward movement of the first sliding sleeve relative to the first column; and / or the second column is provided with a second limiting protrusion, which is located below the second sliding sleeve to limit the downward movement of the second sliding sleeve relative to the second column.

[0024] Compared with the prior art, the advantages of this application are:

[0025] The bed frame provided in this application, when unfolded and viewed from above, has its top divided into three areas: a first support area and two second support areas located on either side of the first support area. When the bed surface is installed on the bed frame, it forms three areas corresponding to the three support areas: a central area corresponding to the first support area, and a head area and a foot area corresponding to the two second support areas. The head area and foot area gradually narrow towards the side away from the central area, resulting in a spindle-shaped structure that is narrow at both ends and wide in the middle. Compared to a traditional rectangular bed surface, because the sides of the bed surface are narrowed, the bed surface formed by the unfolded bed frame provided in this application occupies less space when unfolded, making it more suitable for places with limited head and foot space; moreover, its shape is more unique.

[0041] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] In order to adapt to some usage spaces with limited space at the front and rear, refer to Figure 1-7 As shown, this embodiment provides a foldable bed frame (hereinafter referred to as the bed frame). This bed frame is mainly used for nap beds. Specifically, the bed frame is used to install the bed surface 3 of the nap bed.

[0043] Among them, such as Figure 1 The bed frame shown is a foldable structure, meaning it can be folded (see reference). Figure 6 (shown state) and unfolded state (refer to) Figure 1 The bed frame can be switched between the states shown. When needed, the bed frame can be switched to the unfolded state so that the bed surface 3 can be laid out for the user to lie down. When not in use, the bed frame can be switched to the folded state for easy storage.

[0044] like Figure 1 and Figure 2 As shown, the bed frame provided in this embodiment includes two side frames 1 and a support frame 2:

[0045] Among them, the two side frames 1 are arranged opposite each other along the first direction to support the bed surface 3, such as Figure 1 As shown, the first direction can be understood as the width direction of the bed frame when it is unfolded; correspondingly, in this embodiment, the direction that is horizontal and perpendicular to the first direction is denoted as the second direction, which can also be understood as the length direction of the bed frame when it is unfolded.

[0046] Since the two side frames 1 are basically the same, in this embodiment, for ease of explanation, we will take one of the side frames 1 as an example for specific explanation.

[0047] like Figure 1As shown, the side frame 1 includes a first support 11 and two second supports 12 disposed on both sides of the first support 11, that is, the two side frames 1 are disposed on both sides of the first support 11 along the second direction, and the two side frames 1 are basically symmetrically arranged; wherein, the first support 11 can be extended and folded along the second direction.

[0048] Bed frame in unfolded state:

[0049] like Figure 4 As shown, the tops of the two first supports 11 facing each other along the first direction enclose to form a first support area M1 for supporting the middle area of ​​the bed surface 3, that is, the first supports 11 of the two side frames 1 enclose to form the first support area M1.

[0050] The tops of the two opposing second supports 12 along the first direction enclose each other to form a second support area M2 for supporting the end region of the bed surface 3, that is, as shown in the figure. Figure 4 As shown, in this embodiment, there are two second support areas M2. One is located on the left side of the first support area M1 and is formed by the top of the two second supports 12 on the left side of the two side frames 1. The other is located on the right side of the first support area M1 and is formed by the top of the two second supports 12 on the right side of the two side frames 1. The two second support areas M2 correspond to the front end and the rear end of the bed surface 3, respectively.

[0051] When the nap bed using this bed frame is unfolded for use, such as Figure 7 As shown, the portion of the bed surface 3 that unfolds from the first support area M1 supports the middle area of ​​the human body, and the portions of the bed surface 3 that unfold from the two second support areas M2 support the head side area and the foot area of ​​the human body, respectively.

[0052] Among them, such as Figure 4 As shown, the width of the first support area M1 is equal in the first direction. It can also be understood that, in the top view, when the bed frame is unfolded, both first supports 11 extend along the second direction and the two first supports 11 are parallel to each other, so that the first support area M1 is basically a rectangular area in the top view.

[0053] Furthermore, in the same side frame 1, the second support 12 is inclined relative to the first support 11 at an angle A in the direction of inclination Q1. That is, the angle between the inclination direction Q1 of the second support 12 relative to the first support 11 and the first direction is the angle A. The width of the second support area M2 in the first direction gradually narrows in the second direction away from the first support 11. That is, in the top view, the second support area M2 is basically an isosceles trapezoidal area that gradually narrows away from the first support 11.

[0054] The preferred angle range for included angle A is 85° ≥ included angle A ≥ 75°, for example, 85°, 75°, 80°, etc.

[0055] It is worth noting that, such as Figure 4 As shown, the aforementioned tilt direction Q1 is relative, not absolute; that is, it is relative to the first support 11. Here, the included angle A can be understood as the angle between the inner side of the second support 12 and the first direction in a top-down view. Based on this, the aforementioned tilt direction Q1 can be understood as the direction in a top-down view where the first direction rotates away from the first support area M1 at the included angle A. Therefore, the tilt directions Q1 of the two second supports 12 on the same side frame 1 are basically symmetrically arranged. For example, in... Figure 4 In the top view, taking the upper side frame 1 as an example, the tilt direction Q1 of the second support 12 on the left is diagonally upward to the right, and the tilt direction Q1 of the second support 12 on the right is diagonally upward to the left.

[0056] The second support 12 can be extended and folded along its own tilt direction Q1 relative to the first support 11, so as to ensure that the bed frame can be folded and stowed.

[0057] The support frame 2 is located between the two side frames 1 to support the two side frames 1 in the first direction, so that the two side frames 1 are supported by the support frame 2 after being unfolded, so that the two remain stable in the first direction.

[0058] As can be seen, the bed frame provided in this embodiment, in its unfolded state and in a top-down view, is as follows: Figure 4 As shown, the top of the bed frame is divided into three areas: a first support area M1 and two second support areas M2 located on either side of the first support area M1. When the bed surface 3 is installed on the bed frame, the bed surface 3 can form three areas corresponding to the three support areas: the middle area corresponding to the first support area M1, and the head area and foot area corresponding to the two second support areas M2, respectively. The head area and foot area gradually narrow towards the side away from the middle area, so that the entire bed surface 3 has a spindle-shaped structure that is narrow at both ends and wide in the middle. Compared with the traditional rectangular bed surface 3, because the sides of the bed surface 3 are narrowed, the bed surface 3 formed by the bed frame provided in this embodiment takes up less space when unfolded, and can be more suitable for some places with limited head and foot space; moreover, the shape is more unique.

[0059] In order to enable the first bracket 11 to extend and fold along the second direction, in some embodiments, it is combined with Figure 1 and Figure 3 As shown, the first support 11 includes a first crossbar 111, a first column 112, and two first top rods 116; wherein, the second support 12 is hinged to the end of the first crossbar 111, that is, as shown... Figure 3 As shown, the two second supports 12 in the same side frame 1 are respectively located at the left and right ends of the first cross rod 111.

[0060] The first crossbar 111 includes two first rods 111a, which are hinged together at the middle to form an X-shaped connecting rod structure. The hinge point of the two first rods 111a is called the first hinge point. The hinge axis of the first hinge point is parallel to the first direction, so that the two first rods 111a can be flipped relative to each other around the first hinge point in the second direction to achieve telescopic folding.

[0061] In the unfolded state, the first upright 112 extends basically vertically. The first upright 112 is provided with a first sliding sleeve 113 that can slide relative to the first upright 112 along the axial direction of the first upright 112. That is, the first sliding sleeve 113 slides through the first upright 112 along the axial direction of the first upright 112. The first hinge point is located on the first sliding sleeve 113, that is, the two first rods 111a are hinged to the first sliding sleeve 113. In this way, when the two first rods 111a extend or retract, they drive the first sliding sleeve 113 to slide relative to the first upright 112 along the axial direction of the first upright 112, so as to realize the folding or unfolding of the first support 11 in the second direction.

[0062] like Figure 3 As shown, the first ends of the two first push rods 116 are respectively hinged to the top of the first column 112 around an axis parallel to the first direction. For example, the top of the first column 112 is fixed with a first top hinge seat 115; the first ends of the two first push rods 116 are respectively hinged to both sides of the first top hinge seat 115.

[0063] And when the bed frame is unfolded, such as Figure 3 As shown, the two first top rods 116 extend along the second direction to unfold on both sides of the top of the column, that is, the first top rods 116 are basically in a horizontal state extending along the second direction; thus, in the unfolded state, the two first top rods 116 on one first support 11 and the two first top rods 116 on the other first support 11 together form the aforementioned first support area M1, which is equivalent to the central area of ​​the bed surface 3 being horizontally unfolded by the four first top rods 116.

[0064] Furthermore, in the vertical direction: the upper ends of the two first rods 111a are respectively hinged to first hinge seats R1, and the hinge axis of the first rod 111a and the first hinge seat R1 is parallel to the first direction; the lower ends of the two first rods 111a are respectively hinged to second hinge seats R2, and the hinge axis of the second rod 121a and the second hinge seat R2 is also parallel to the first direction.

[0065] Furthermore, the second end of the first push rod 116 (i.e. the end of the first push rod 116 away from the first top hinge seat 115) is hinged to the first hinge seat R1 on the same side, and the hinge axis of the two is parallel to the first direction.

[0066] In order to enable the second bracket 12 to extend and fold along its tilt direction Q1 relative to the first bracket 11, in some embodiments, it is combined with Figure 1 and Figure 3 As shown, the second support 12 includes a second cross rod 121, a second column 122, and two second top rods 126.

[0067] The second crossbar 121 includes two second bars 121a, which are hinged at the middle to form an X-shaped linkage structure, such as Figure 4 As shown, the hinge point of the two second rods 121a is denoted as the second hinge point. The hinge axis of the second hinge point (for distinction, this hinge axis is denoted as the first axis L1) is perpendicular to the tilt direction Q1. Here, the tilt direction Q1 refers to the tilt direction of the second support 12 and the first support 11, including the second cross rod 121. At this time, the tilt angle A between the second support 12 and the first support 11 can also be understood as, for example... Figure 4 As shown, in a top-down view, the angle between the second rod 121a and the first direction.

[0068] like Figure 1 and Figure 3 As shown, among the ends of the two second rods 121a adjacent to the first cross rod 111, the one located on the upper side is hinged to the first hinge seat R1, and the hinge axis of the second rod 121a hinged to the first hinge seat R1 is denoted as the second axis L2, which is perpendicular to the inclination direction Q1 of the second support 12 relative to the first support 11; the one located on the lower side is hinged to the second hinge seat R2, and the hinge axis of the second rod 12a hinged to the second hinge seat R2 is denoted as the third axis L3, which is perpendicular to the inclination direction Q1 of the second support 12 relative to the first support 11.

[0069] The second column 122 extends basically vertically. The second column 122 is provided with a second sliding sleeve 123 that can slide relative to the second column 122 along the axis of the second column 122. The second sliding sleeve 123 is sleeved on the second column 122. The second hinge point is located on the second sliding sleeve 123, that is, the two second rods 121a are hinged to the second sliding sleeve 123.

[0070] Two second push rods 126 are provided, with their tops hinged to the top of the second column 122 around a hinge axis perpendicular to the inclined direction Q1. For example, the top of the second column 122 is fixed with a second top hinge seat 125, and the first ends of the two second push rods 126 are respectively hinged to both sides of the second top hinge seat 125. The hinge axis between the second push rods 126 and the second top hinge seat 125 is denoted as the fourth axis L4. Figure 4 As shown, in a top view, the fourth axis L4 is perpendicular to the tilt direction Q1 of the second bracket 12 relative to the first bracket 11.

[0071] Of the two second push rods 126, the second end of one of them (i.e., the end furthest from the second top hinge seat 125) is hinged to the first hinge seat R1 around the fifth axis L5, wherein... Figure 4 As shown, the fifth axis L5 is perpendicular to the inclined direction Q1, and the second end of the other axis is hinged to the support frame 2 around the sixth axis L6, as shown. Figure 4 As shown, the sixth axis L6 is perpendicular to the tilt direction Q1. This allows the second support to extend and fold along the tilt direction Q1.

[0072] When the bed frame is unfolded, as follows: Figure 3 and Figure 4 As shown, the two second top rods 126 extend along the inclined direction Q1 to unfold on both sides of the top of the second column 122, that is, the second top rods 126 are basically in a horizontal state extending along the inclined direction Q1; thus, in the unfolded state, the two second top rods 126 on one of the second supports 12 and the two second top rods 126 on the other second support 12 opposite to it in the first direction together form the aforementioned second support area M2, which is equivalent to the middle area of ​​the bed surface 3 being horizontally unfolded by the four second top rods 126 to form an isosceles trapezoidal structure.

[0073] In addition, in order to limit the lower position of the first sliding sleeve 113, in some embodiments, such as Figure 1 and Figure 3 As shown, the first column 112 is provided with a first limiting protrusion 114. The first limiting protrusion 114 is located below the first sliding sleeve 113 and is used to restrict the first sliding sleeve 113 from moving downward relative to the first column 112. That is, when the bed frame is unfolded, the first sliding sleeve 113 is blocked by the first limiting protrusion 114 and cannot continue to move downward relative to the first column 112. Similarly, in order to limit the second sliding sleeve 123 downward, the second column 122 is provided with a second limiting protrusion 124. The second limiting protrusion 124 is located below the second sliding sleeve 123 and is used to restrict the second sliding sleeve 123 from moving downward relative to the second column 122. That is, when the bed frame is unfolded, the second sliding sleeve 123 is blocked by the second limiting protrusion 124 and cannot continue to move downward relative to the second column 122.

[0074] In order to enable the support frame 2 to extend and fold along the first direction, in some embodiments, the support frame 2 includes a third crossbar 21 disposed between the two side frames 1.

[0075] like Figure 2 As shown, the third intersecting rod 21 includes two third rods 21a hinged together at their middle parts, as... Figure 4 As shown, the hinge axis L7 of the two third rods 21a is parallel to the second direction; in some embodiments, such as Figure 4As shown, two third crossbars 21 are provided, one of which is located between the two first hinge seats R1 on the left and the other is located between the two first hinge seats R1 on the right.

[0076] Taking one of the third crossbars, 21, as an example: Figure 2 As shown, among the ends of the two third rods 21a adjacent to the side frame 1, the one on the upper side is hinged to the first hinge seat R1, and its hinge axis is parallel to the second direction; the one on the lower side is hinged to the second hinge seat R2, and its hinge axis is also parallel to the second direction; it can also be understood that the upper two ends of the third cross rod 21 are respectively hinged to the two first hinge seats R1, and the lower two ends are respectively hinged to the two second hinge seats R2.

[0077] In this embodiment, the aforementioned included angle A can also be understood as, for example Figure 4 As shown, in the top view, the angle between the third cross bar 21 and the second support 12, or in the top view, the angle between the third bar 21a and the second bar 121a; the corresponding tilt direction Q1 of the second support 12 relative to the first support 11 can also be understood as the extension direction of the second bar 121a in the top view.

[0078] In addition, in order to provide support for both ends of the two side frames 1 in the first direction, the support frame 2 also includes two scissor links 22 that are telescopic in the vertical and first direction and located between the ends of the two side frames 1.

[0079] like Figure 2 As shown, the scissor link 22 is located at both ends of the adjacent side frame 1. The upper one is hinged to a third hinge seat R3 around a hinge axis parallel to the second direction, and the lower one is hinged to a fourth hinge seat R4 around a hinge axis parallel to the second direction. At both ends of the two second rods 121a on the side away from the first support 11, the upper one is hinged to the third hinge seat R3, and the lower one is hinged to the fourth hinge seat R4. The hinge axes of the second rod 121a and the third hinge seat R3, as well as the hinge axis of the second rod 121a and the fourth hinge seat R4, are all perpendicular to the tilt direction Q1.

[0080] As a specific implementation method, such as Figure 2 As shown, the scissor link 22 includes one or more cross rods that are hinged together vertically. For example, in this embodiment, the scissor link 22 includes two fourth cross rods 221. Each fourth cross rod 221 includes two fourth rods 221a that are hinged together in the middle. The lower ends of the upper fourth cross rod 221 are respectively hinged to the upper ends of the lower fourth cross rod 221. In the scissor link 22, the hinge axis of each hinge point is parallel to the second direction.

[0081] The upper ends of the fourth cross rod 221 located on the upper side are hinged to the two third hinge seats R3 respectively, and the lower ends of the fourth cross rod 221 located on the lower side are hinged to the two fourth hinge seats R4 respectively.

[0082] By using the support frame 2 and the side frames 1 as described above, the bed frame can have a spindle-shaped structure that is wider in the middle and narrower at both ends when unfolded; and when folded, as... Figure 5 As shown, this allows the entire side frame 1 to be extended and folded in the second direction, and the support frame 2 to be extended and folded in the first direction, so that the entire bed frame ultimately presents a bundle-like folded state, as shown. Figure 6 As shown in the image.

[0083] Example 2

[0084] Combination Figure 1-7 As shown, this embodiment further provides a nap bed based on embodiment 1, including the bed frame provided in embodiment 1 and a bed surface 3 installed on the bed frame. The bed surface 3 is a flexible structure; for example, the bed surface 3 can be made of flexible materials such as textile fabric. The bed surface 3 can be connected to the top of the two side frames 1.

[0085] The nap bed provided in this embodiment, when unfolded, has a bed surface 3 that is rectangular in the middle and gradually narrows at both ends in a spindle shape. This not only meets the user's normal lying needs but also reduces the space occupied by the head and tail of the nap bed, thus making it more suitable for places with limited head and tail space.
