Description

Technical Field

[0001] The utility model relates to the technical field of furniture, in particular to a bed foot, a bed frame and a bed. Background Art

[0002] A bed is a daily necessity that can meet people's daily sleep needs. A bed generally includes a bed frame and a mattress. The mattress is placed on the bed frame to provide people with a soft and comfortable sleeping environment. The bottom of the bed frame is generally provided with bed legs to support the bed frame. Beds can be divided into flush beds and built-in beds. It can be understood that a flush bed means that the periphery of the bed frame is flush with the periphery of the mattress in the vertical direction; while a built-in bed means that the periphery of the bed frame is provided with a surrounding edge, which can surround the mattress, thereby limiting the mattress and preventing the mattress from moving.

[0003] When it is necessary to replace the fitted sheet for the mattress, the fitted sheet should be put on the mattress to wrap the mattress, thereby protecting the mattress. However, since the surrounding edge of the built-in bed surrounds the mattress, it is extremely inconvenient to replace the fitted sheet. In order to adjust the height of the bed frame according to one's own needs, a bed foot support connector is proposed in the related art. When the bed foot support connector is used, it is necessary to pull up the height adjustment sleeve so that the height adjustment sleeve and the support rod move relative to each other, and insert the limit plug rod on the height adjustment sleeve into the limit plug hole and the plug hole on the support rod to achieve the limit fixation of the height adjustment sleeve and the support rod. If the above-mentioned bed foot support connector is applied to the built-in bed, although the height of the bed frame can be adjusted to facilitate the replacement of the fitted sheet, it is also quite difficult in actual operation, especially when operated by one person, it is difficult to lift the height adjustment sleeve, and it is even more difficult to maintain it at a certain height so that the limit plug rod on the height adjustment sleeve can be inserted and installed in the limit plug hole and the plug hole on the support rod, which is time-consuming and laborious.

DETAILED DESCRIPTION

[0032] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0033] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0034] In the description of the present utility model, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood to exclude the number itself, and "above", "below", "within" etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0035] In the description of the present utility model, unless otherwise clearly defined, words such as setting and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above words in the present utility model based on the specific content of the technical solution.

[0036] The technical solution of the present application will be further described below in conjunction with embodiments and drawings.

[0037] It can be understood that in the embodiments of the present application, the positive direction of the Z axis in the drawings is taken as the top, and the negative direction of the Z axis is taken as the bottom.

[0038] See also Figure 1 and Figure 2 The first embodiment of the present application provides a bed foot 100 that can be raised, so that the bed frame and the mattress 200 can be raised relative to the surrounding edge 300, thereby leaving the periphery of the mattress 200 vacant, making it convenient to replace the fitted sheet and saving time and effort.

[0039] The foot of the bed 100 includes a foot body 110, a support member 120, a first limiting portion 133 and a pressing portion 134. The support member 120 is connected to the foot body 110 through an elastic member 140. The first limiting portion 133 is connected to the foot body 110. The support member 120 is provided with a second limiting portion 121. The first limiting portion 133 is detachably connected to the second limiting portion 121, so that the first limiting portion 133 can be connected to the second limiting portion 121 and can also be separated from the second limiting portion 121. When the limiting portion 133 is connected to the second limiting portion 121, the support member 120 stops and compresses the elastic member 140, so that the elastic member 140 generates an elastic force. When the first limiting portion 133 is separated from the second limiting portion 121, the elastic force generated by the elastic member 140 can push the support member 120 to move upward. The pressing portion 134 is connected to the first limiting portion 133 or the second limiting portion 121. The first limiting portion 133 can be separated from the second limiting portion 121 by pressing the pressing portion 134.

[0040] It can be understood that one or more first limiting parts 133 can be provided, and one or more second limiting parts 121 can be provided. The specific positions and specific numbers of the first limiting parts 133 and the second limiting parts 121 can be set according to actual needs, and no specific restrictions are made here.

[0041] Exemplarily, two first limit portions 133 and two second limit portions 121 are provided, and the first limit portions 133 and the second limit portions 121 correspond one to one. Optionally, the two second limit portions 121 are circumferentially arranged on the support member 120, and the two second limit portions 121 are symmetrically arranged.

[0042] In some embodiments, the bed foot 100 further includes a metal spring 130, which is connected to the bed foot body 110. Figures 3 to 5 The metal spring piece 130 has two side surfaces 1311 arranged opposite to each other, two first limiting portions 133 are respectively arranged on the two side surfaces 1311 of the metal spring piece 130, and a pressing portion 134 is arranged in the middle of the metal spring piece. By pressing the pressing portion 134, the two side surfaces 1311 of the metal spring piece 130 can be deformed toward the opposite side (see Figure 5 ), so that each first limiting portion 133 can be separated from the corresponding second limiting portion 121. That is, the pressing portion 134 in this embodiment is connected to the first limiting portion 133 through the metal spring 130.

[0043] For example, see Figure 3 and Figure 4The metal spring 130 is symmetrically arranged, and includes two symmetrically arranged curved portions 131 and an arc-shaped portion 132. The two ends of the arc-shaped portion 132 are respectively connected to the two curved portions 131. The arc-shaped portion 132 is concavely arranged, and the two curved portions 131 are both convexly arranged. The two side surfaces 1311 are respectively arranged at one end of the two curved portions 131 away from the arc-shaped portion 132. Optionally, the pressing portion 134 is arranged in the middle of the arc-shaped portion 132.

[0044] Of course, in other embodiments, the metal spring 130 may also be configured into other shapes as long as it can achieve the above functions, and no specific limitation is made here.

[0045] In some embodiments, the first limiting portion 133 is a limiting pin, and the second limiting portion 121 is a limiting hole. The limiting pin is connected to the foot body 110, and the limiting hole is set on the support member 120. The limiting pin can be inserted into the limiting hole, and the limiting pin can also be separated from the limiting hole. When the limiting pin is embedded in the limiting hole, the support member 120 stops and compresses the elastic member 140, so that the elastic member 140 generates an elastic force; when the limiting pin is separated from the limiting hole, the elastic force generated by the elastic member 140 pushes the support member 120 to move upward.

[0046] Exemplarily, two limiting pins are respectively arranged on two side surfaces 1311 of the metal spring sheet 130, and two limiting holes are symmetrically arranged at the upper end of the support member 120, so that the support member 120 can be evenly stressed. Figure 6 When the support member 120 is in the initial state, the two limit pins are respectively inserted into the two limit holes to limit the support member 120. If the support member 120 needs to be raised, only one pressing portion 134 is needed, and the arc portion 132 in the middle of the metal spring sheet 130 is subjected to the squeezing force, causing the bent portions 131 on both sides of the metal spring sheet 130 to deform outwards, that is, the two side surfaces 1311 of the metal spring sheet 130 will deform toward the opposite side (see Figure 5 ), so that each limit pin in each limit hole can be pulled out, thereby losing the limit stop on the support member 120. At this time, the elastic force generated by the elastic member 140 can push the support member 120 to move upward (see Figure 7 ), easy to operate, time-saving and labor-saving. If it is necessary to restore the initial state of the bed foot 100, press the support member 120 downward until the limiting holes on the support member 120 are aligned with the limiting pins on the two side surfaces 1311 of the metal spring sheet 130, and the two bent portions 131 of the metal spring sheet 130 will rebound, and the limiting pins will be inserted into the limiting holes on the support member 120. It can be understood that the metal spring sheet 130 can allow a certain range of deformation, and can automatically restore to its original state after deformation, so that the metal spring sheet 130 can generate a rebound force.

[0047] Of course, in other embodiments, the first limiting part and the second limiting part can also be set as other detachable connection structures, which are not specifically limited here. For example, the first limiting part can be a limiting hole, the second limiting part can be a limiting pin, the second limiting part (limiting pin) is connected to the support member 120 through a spring, the pressing part is arranged at the end of the second limiting part (limiting pin) away from the support member 120 (that is, the pressing part is connected to the second limiting part), and the first limiting part (limiting hole) is arranged on the foot body 110 and is opposite to the second limiting part (limiting pin). When the support member 120 is in the initial state, the spring is in the natural state, the second limiting part (limiting pin) is inserted into the first limiting part (limiting hole), and the support member 120 can be limited and stopped, and the pressing part extends from the first limiting part (limiting hole) to the foot body 110 for the user to press. If the support member 120 needs to be raised, the pressing part is pressed, the spring is compressed, the second limiting part (limiting pin) and the pressing part are pressed into the foot body 110, and the second limiting part (limiting pin) is separated from the first limiting part (limiting hole), thereby losing the limiting stop of the support member 120. At this time, the elastic force generated by the elastic member 140 can push the support member 120 to move upward. If the bed foot 100 needs to be restored to its original state, the support member 120 is pressed downward until the second limiting part (limiting pin) on the support member 120 is aligned with the first limiting part (limiting hole) on the foot body 110, and the second limiting part (limiting pin) will rebound into the first limiting part (limiting hole).

[0048] However, with this structural arrangement, if both the first limiting portion (limiting hole) and the second limiting portion (limiting pin) are provided as one, the support member 120 is susceptible to uneven force and the spring is also susceptible to damage; if both the first limiting portion (limiting hole) and the second limiting portion (limiting pin) are provided as multiple portions, multiple pressing portions need to be pressed simultaneously, which is inconvenient to operate.

[0049] The following is an example of "the first limiting portion 133 is a limiting pin, the second limiting portion 121 is a limiting hole, the two limiting pins are respectively arranged on the two side surfaces 1311 of the metal spring sheet 130, and the two limiting holes are circumferentially symmetrically arranged at the upper end of the support member 120".

[0050] In some embodiments, a first limiting groove 1122 and a first through hole 160 are provided on the foot body 110, the first through hole 160 is connected to the first limiting groove 1122, the metal spring 130 is provided in the first limiting groove 1122, the first limiting groove 1122 can limit the metal spring 130, and the pressing portion 134 can extend out of the foot body 110 through the first through hole 160 to facilitate the user to press the pressing portion 134.

[0051] In some embodiments, see Figure 1 and Figure 2The foot body 110 includes a cylinder 112 and a cover 111, the cover 111 is connected to the upper end of the cylinder 112, the cylinder 112 is hollow, the support member 120 is movably arranged in the cylinder 112, and the cover 111 is provided with a second through hole 1111 for the support member 120 to pass through. Optionally, the cover 111 is connected to the upper end of the cylinder 112 by screws 150.

[0052] Alternatively, see Figure 8 The first limiting groove 1122 is arranged at the upper end of the cylinder 112 and at the outer periphery of the support member 120. When the cover 111 covers the upper end of the cylinder 112, the first limiting groove 1122 can be covered to further limit the metal spring 130, and a first through hole 160 can be formed to allow the pressing portion 134 to extend out of the foot body 110. It can be understood that the first through hole 160 can also play a role in radially limiting the pressing portion 134, but does not affect the axial pressing of the pressing portion 134.

[0053] In some embodiments, a limiting block 11221 is disposed on the side wall of the first limiting groove 1122 , and the limiting block 11221 is used to abut against the opposite sides of the two side surfaces of the metal spring 130 after the first limiting portion 133 is separated from the second limiting portion 121 .

[0054] For example, two limiting blocks 11221 are circumferentially arranged on the side wall of the first limiting groove 1122, and each limiting block 11221 is located on the back side of each limiting pin (see Figure 4 ), the two limit blocks 11221 can respectively press against the two bent portions 131 of the metal spring 130 after the first limit portion 133 is separated from the second limit portion 121, thereby preventing the two bent portions 131 of the metal spring 130 from being excessively deformed, and at the same time protecting the metal spring 130, it is also beneficial for the limit pin to be inserted into the limit hole again.

[0055] It is understandable that the specific number and specific location of the limit blocks 11221 can be set according to actual needs and are not specifically limited here.

[0056] Alternatively, see Figure 8 Two symmetrical second limiting grooves 1123 are also provided at the upper end of the cylinder 112, which are used to place two limiting pins respectively, so as to prevent the limiting pins from deviating when leaving the limiting holes, and facilitate the limiting pins to be inserted into the limiting holes again.

[0057] In some embodiments, the foot body 110 is provided with a slide groove 1121 along its length direction, see Fig. 9 The cylinder 112 is provided with a slide groove 1121 along its length direction, see Figure 2A third limiting portion 122 is provided on the support member 120, and the third limiting portion 122 extends into the slide groove 1121 and can move along the length direction of the slide groove 1121. The slide groove 1121 has an upper side wall, and the upper side wall is used to resist the third limiting portion 122, so that the support rod can be limited when the support rod moves upward to prevent the support rod from escaping from the cylinder 112.

[0058] Optionally, the third limiting portion 122 may be a limiting shaft. Of course, the third limiting portion 122 may also be a limiting block or other limiting structures with limiting functions, which are not specifically limited here.

[0059] Optionally, a limiting structure such as a limiting block may be provided on the upper side wall of the slide groove 1121 to resist the third limiting portion 122 , and no specific limitation is made here.

[0060] It is understandable that when the upper side wall of the slide groove 1121 abuts against the third limit portion 122, the support member 120 reaches the maximum rising height, and the elastic member 140 is still in a compressed state and maintains a certain elastic force to support the bed frame body and the mattress 200. At this time, the bed frame body and the mattress 200 can be raised relative to the surrounding edge 300, thereby making the outer periphery of the mattress 200 vacant, which is convenient for replacing the fitted sheet. In other words, the maximum rising height of the support member 120 needs to meet the condition that the bottom of the mattress 200 is higher than the top of the surrounding edge 300, so as to replace the fitted sheet on the mattress 200.

[0061] Of course, the above scheme can also be equivalently replaced as follows: the support member 120 is provided with a slide groove along its length direction, and a limiting shaft is provided on the cylinder 112, the limiting shaft extends into the slide groove, the slide groove has a lower side wall, and the limiting shaft is used to resist the lower side wall of the slide groove, so that the support member 120 can be limited when the support member 120 moves upward to prevent the support member 120 from escaping from the cylinder 112.

[0062] In some embodiments, see Figure 2 The support member 120 is a cylindrical support rod. Of course, the support member 120 can also be a support column of other shapes or other structures with a supporting function, which is not specifically limited here.

[0063] In some embodiments, see Figure 2 The foot body 110 further includes a base 113, which is also connected to the bottom end of the cylinder 112 by screws 150. Figure 2 The base 113 is provided with a protrusion 1131 for connecting with the elastic member 140 .

[0064] In some embodiments, the elastic member 140 is a spring, one end of the spring is connected to the foot body 110, and the other end of the spring is connected to the support member 120. Figure 2 and Figure 7 One end of the spring away from the support member 120 is sleeved on the protrusion 1131 of the base 113 .

[0065] Other structures and operations of the bed foot 100 according to the first embodiment of the utility model are known to those skilled in the art and will not be described in detail here.

[0066] The second embodiment of the present invention provides a bed frame, which includes the bed legs 100 of the first embodiment of the present invention, and also includes a bed frame body (not shown in the drawings), the bed legs 100 are arranged at the bottom of the bed frame body, and the upper end of the support member 120 is connected to the bed frame body.

[0067] Optionally, the bed frame is a slat frame. The slat frame can be a double-row slat frame, or other multi-row or single-row slat frames. Of course, the bed frame can also be a bed frame of other structures, which is not specifically limited here.

[0068] Optionally, four bed legs 100 are provided, and the four bed legs 100 are respectively arranged at the bottom of the four corners of the bed frame body, and the upper end of the support member 120 of each bed leg 100 is connected to the bed frame body.

[0069] Other structures and operations of the bed frame according to the embodiment of the second aspect of the utility model are known to ordinary technicians in the field and will not be described in detail here.

[0070] See also Fig.10 and Fig.11 The third aspect of the present invention provides a bed, which includes the bed frame of the second aspect of the present invention.

[0071] Furthermore, the bed also includes a mattress 200 and a surrounding edge 300 . The mattress 200 is arranged on a bed frame body. The surrounding edge 300 surrounds the mattress 200 and the bed frame body. The bed frame body can move up and down relative to the surrounding edge 300 .

[0072] Exemplarily, the bed further includes a bedside 400 , both ends of the surrounding edge 300 are connected to the bedside 400 , and two supporting legs 310 are spaced apart at the bottom of the surrounding edge 300 away from the bedside 400 .

[0073] When the bed in the third embodiment of the present invention needs to be replaced with a fitted sheet, the pressing portion 134 can be pressed, and the arc portion 132 in the middle of the metal spring sheet 130 is subjected to a squeezing force, causing the bent portions 131 on both sides of the metal spring sheet 130 to deform outwards, that is, the two side surfaces 1311 of the metal spring sheet 130 are deformed toward opposite sides (see Figure 5), so that each limiting pin in each limiting hole can be pulled out, thereby losing the limiting stop on the support member 120. At this time, the elastic force generated by the elastic member 140 can push the support member 120 to move upward to the maximum rising height (the maximum rising height of the support member 120 must meet the condition that the bottom of the mattress 200 is higher than the top of the surrounding edge 300). At this time, the elastic member 140 is still in a compressed state and maintains a certain elastic force to support the bed frame body and the mattress 200. At this time, the bed frame body and the mattress 200 can be raised relative to the surrounding edge 300, thereby leaving the periphery of the mattress 200 empty (see Fig.11 ), making it easy to change the fitted sheet.

[0074] After replacing the fitted sheet, it is necessary to restore the bed foot 100 to its original state. The support member 120 can be pressed downward until the limiting holes on the support member 120 are aligned with the limiting pins on the two side surfaces 1311 of the metal spring sheet 130. The two bent portions 131 of the metal spring sheet 130 will rebound, and the limiting pins will be inserted into the limiting holes on the support member 120.
