Description

Technical Field

[0001] This invention relates to the technical field of beds, and more specifically to an automatic webbing winding device and a bedside bed including the same. Background Technology

[0002] Bedside beds (such as cribs) make it convenient for caregivers to look after infants and toddlers, especially to address the issue of caregivers needing to get up frequently at night to care for their babies. Caregivers often purchase bedside beds that are the same height as adult beds, allowing them to easily monitor their babies while sleeping. To secure the bedside bed relative to the adult bed and avoid a large gap between them, webbing is usually used to secure it. However, if the user doesn't roll up the webbing, it can appear messy and untidy. Furthermore, when not in use (when the bedside bed is not being secured), the webbing cannot automatically roll up, making it inconvenient for the user to do so, and there's also the possibility that the webbing might be removed and lost.

[0003] Therefore, it is necessary to provide an automatic webbing winding device and a bedside bed including the same to overcome the shortcomings of the prior art. Summary of the Invention

[0004] In view of this, in order to solve the above problems, the present invention aims to provide an automatic webbing winding device and a bedside bed including the same.

[0005] The present invention provides an automatic webbing winding device suitable for engaging with a fixing member. The automatic webbing winding device includes: a base; a reel mounted on the base and rotatable about the center of the base; a coil spring mounted on the reel, with one end fixed to the reel and the other end fixed to the base; and a webbing mounted on the reel, with the fixed end of the webbing fixed to the reel and the free end of the webbing extending out of the automatic webbing winding device. When the free end of the webbing is pulled outward under external force, the reel rotates in the forward direction to wind the coil spring tightly. When the external force is removed, under the tension of the coil spring, the reel rotates in the reverse direction, thereby winding the webbing onto the reel.

[0006] In one embodiment, the base includes a bottom surface and sidewalls surrounding a housing. A protrusion is located at the center of the bottom surface, and a slit is provided in the sidewalls. A reel has a through-hole corresponding to the protrusion at its center. The reel is mounted within the housing and on the bottom surface, with the through-hole surrounding the protrusion. A coil spring is sleeved around the protrusion and located on the reel, with one end fixed to the protrusion and the other end fixed to the reel. The webbing is wound into a loop, with its fixed end fixed to the reel and its free end passing through the slit in the sidewall.

[0007] In one embodiment, the automatic webbing take-up device further includes a reel cover mounted on the reel and covering the webbing, the coil spring, and the reel.

[0008] In one embodiment, the automatic webbing take-up device further includes a base cover fixed to the base and covering the base. Optionally, the base cover is made of a flexible material.

[0009] In one embodiment, the reel includes a flange disposed around the perforation, and the bottom surface includes an annular protrusion disposed around the protrusion, the annular protrusion corresponding to the flange such that the flange is accommodated in the annular region formed by the annular protrusion and the protrusion.

[0010] In one embodiment, the reel further includes a plurality of protruding ribs extending from the flange.

[0011] In one embodiment, the bottom surface further includes a plurality of protruding ribs extending from the annular protrusion.

[0012] In one embodiment, the sidewall of the protrusion has a cutout for engaging one end of the coil spring.

[0013] In one embodiment, the cross-section of the cut is Y-shaped.

[0014] In one embodiment, the reel further includes two semi-annular protrusions disposed opposite each other on one side, and a lug located between the opposite ends of the two semi-annular protrusions; the semi-annular protrusions surround the flange and are located on the periphery of the flange, one end of the semi-annular protrusions narrows, and a gap is formed between the narrowed ends of the two semi-annular protrusions.

[0015] In one embodiment, the two ends of the coil spring are wound up to be fitted into the base and the reel.

[0016] In one embodiment, the automatic webbing take-up device further includes a locking member disposed at the free end of the webbing.

[0017] The present invention also provides a bedside bed, comprising a base plate and a plurality of side plates, the base plate being generally parallel to the ground, and the plurality of side plates being generally perpendicular to the ground and surrounding the base plate. The bedside bed is characterized in that at least one of the side plates has a webbing outlet and includes an automatic webbing winding device, the automatic webbing winding device comprising: a base; a reel mounted on the base and rotatable about the center of the base; a coil spring mounted on the reel, one end fixed to the reel and the other end fixed to the base; and a webbing mounted on the reel, with the fixed end of the webbing fixed to the reel, the free end of the webbing extending from the automatic webbing winding device and protruding from the webbing outlet outside the bedside bed; wherein, when the free end of the webbing is pulled outward under external force, the reel rotates in the forward direction to wind the coil spring tightly; and when the external force is removed, under the tension of the coil spring, the reel rotates in the reverse direction to wind the webbing onto the reel.

[0018] In one embodiment, the automatic webbing winding device further includes a locking member disposed at the free end of the webbing, the locking member including a first locking member and a second locking member, which fix the free end of the webbing to the bed near the bedside bed through the locking action.

[0019] In one embodiment, the base of the automatic webbing winding device is integrally formed on the side plate.

[0020] In one embodiment, the base of the automatic webbing winding device is mounted on the side plate via a connector.

[0021] The automatic webbing winding device of the present invention has one end of a coil spring secured to a base and the other end secured to a reel. When no external force is applied to the webbing, the webbing remains in an automatic winding state under the action of the coil spring. When the webbing is to be used, pulling the webbing outward causes the reel to rotate counterclockwise or clockwise, thereby winding the coil spring and storing its winding force. When the external force is removed, the tension of the coil spring causes it to rotate clockwise or counterclockwise, and the reel winds the webbing onto the reel one turn at a time, achieving the purpose of winding the webbing. Therefore, the automatic webbing winding device of the present invention can automatically wind up excess webbing when it is not in use or during use, resulting in a neater and more convenient system, and preventing the webbing from being discarded and lost after being removed.

[0035] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] According to one embodiment of the present invention, an automatic webbing winding device is provided, which is adapted to engage with a fixing member, such as a bedside table. Figures 1 to 11 As shown, the automatic webbing winding device 10 includes: a base 101, which includes a bottom surface 1011 and a side wall 1012 surrounding a housing; a protrusion 1013 is provided at the center of the bottom surface 1011, and a gap 1014 is provided in the side wall 1012; a winding reel 102, which has a through hole 1021 at its center corresponding to the protrusion 1013; the winding reel 102 is installed inside the housing and located on the bottom surface 1011, and the through hole 1021 surrounds the protrusion 1013; and a coil spring 103, which is sleeved around the protrusion 1013 and located on the winding reel 102. One end of spring 103 is fixed to the protrusion 1013, and the other end is fixed to the reel 102; and a webbing 104 is wound into a ring, with its fixed end fixed to the reel 102 and its free end 1042 passing through the gap 1014 of the sidewall; wherein, when the free end 1042 of the webbing 104 is pulled outward under the action of an external force, the reel 102 rotates in the forward direction to make the coil spring 103 tightly wound; and when the external force is removed, under the tension of the coil spring 103, the reel 102 rotates in the reverse direction to wind the webbing 104 onto the reel. In some embodiments, the forward direction may be clockwise, and the reverse direction may be counterclockwise, and vice versa.

[0037] The automatic webbing take-up device 10 may further include a reel cover 105 with a central through hole aligned with a protrusion 1013 of the base 101. This cover is mounted on the reel 102 and covers the webbing 104, the coil spring 103, and the reel 102. The automatic webbing take-up device 10 may also include a base cover 106, which is fixed to the base 101 and covers the housing of the base 101. Figure 1 , 10As shown in Figure 11, the base cover 106 has a hole in its center. Optionally, the protrusion 1013 of the base 101 also has a central through hole. The hole in the center of the base cover 106 is aligned with the central through hole of the protrusion 1013 of the base 101, and the two can be fixed together by screws or bolts. When the base 101 is integrally formed on the side plate 201 of the bedside bed 20, the central through hole of the protrusion 1013 of the base 101 is directly provided on the side plate 201. The base cover 106 can be fixed to the side plate 201 by screws or bolts, thereby covering the base 101 and its other internal components. In some embodiments, the base cover 106 may use a flexible material, such as being made of or wrapped with a flexible material, to prevent infants from being injured by collisions inside the bed.

[0038] In this embodiment, the base 101 is integrally formed on the side plate 201 of the bedside bed 20, that is, the bottom surface 1011 of the base 101 is integrally formed with the side plate 201, and the side wall 1012 is also integrally formed with both. However, optionally, the base 101 can also be a separate component, that is, not integrally formed with the side plate 201, and the bottom surface 1011 and the side wall 1012 may not be integrally formed; the two can be connected by means known in the art.

[0039] In some embodiments, such as Figure 12 , 13 As shown, the automatic webbing take-up device 10 may further include a locking member 107 disposed at the free end 1042 of the webbing 104. The locking member 107 includes a first locking member 1071 and a second locking member 1072, which, through their locking action, fix the free end 1042 of the webbing 104 to the bed (not shown) near the bedside bed 20. The locking member 107 may also be other forms common in the art, as long as it can achieve the function of fixing the webbing 104 to the bed.

[0040] refer to Figure 2 , Figure 3 as well as Figure 6 The bottom surface 1011 of the base 101 includes an annular protrusion 10111 surrounding the protrusion 1013. The reel 102 includes a flange 1022 surrounding the perforation 1021, the flange 1022 being formed on both sides of the reel 102. The annular protrusion 10111 corresponds to the flange 1022 of the reel 102, such that the flange 1022 is received within the annular region formed by the annular protrusion 10111 and the protrusion 1013. Thus, by receiving the flange 1022 of the reel 102 within the annular region formed by the annular protrusion 10111 and the protrusion 1013, the position of the reel 102 can be restricted, making it more stable during rotation.

[0041] like Figure 3As shown, the reel 102 also includes multiple protruding ribs 1023 extending from the flange 1022. The height of the protruding ribs 1023 relative to the main plane of the reel 102 is the same as that of the flange 1022, meaning the protruding ribs 1023 and the flange 1022 are in the same plane. Optionally, the protruding ribs 1023 are symmetrically arranged; in this embodiment, eight symmetrically arranged protruding ribs 1023 are provided. By providing the protruding ribs 1023, the contact area between the coil spring 103 and the reel 102 is reduced, as is the friction between them, when the coil spring 103 is mounted on the reel 102.

[0042] like Figure 2 As shown, the bottom surface 1011 of the base 101 also includes multiple protruding ribs 10112 extending from the annular protrusion 10111. The protruding ribs 10112 are at the same height as the annular protrusion 10111 relative to the bottom surface 1011, meaning the annular protrusion 10111 and the protruding ribs 10112 are in the same plane. Optionally, the protruding ribs 10112 are symmetrically arranged; in this embodiment, eight symmetrically arranged protruding ribs 10112 are provided. By providing the protruding ribs 10112, the contact area between the reel 102 and the base 101 is reduced, as is the friction between them, when the reel 102 is mounted on the base 101. The sidewall of the protrusion 1013 of the base 101 has a cutout 10131 for securing one end of the coil spring 103. Figure 8 , 9 As shown, the cross-section of the cut 10131 is Y-shaped, so that when the coil spring 103 is clamped, it can be clamped in two directions. One end of the coil spring 103 can be clamped on the left side of the Y-shaped cut 10131 or on the right side of the cut 10131. Figure 9 The diagram shows the coil spring 103 positioned on the right side of the Y-shaped cut 10131. When an external force pulls on the webbing 104, the coil spring 103 will coil counterclockwise, and when the external force is removed, the tension of the coil spring 103 will tighten the webbing 104 clockwise. Conversely, if the coil spring 103 is positioned on the left side of the Y-shaped cut 10131, it will coil clockwise when an external force pulls on the webbing 104, and tighten counterclockwise when the external force is removed.

[0043] like Figure 3As shown, the reel 102 also includes two opposing semi-annular protrusions 1024 on one side, and a lug 1025 located between the opposing ends of the two semi-annular protrusions 1024. The semi-annular protrusions 1024 surround the flange 1022 and are located on the periphery of the flange 1022. One end of the semi-annular protrusions 1024 narrows, forming a gap 1026 between the narrowed ends of the two semi-annular protrusions 1024. The gap 1026 is used to engage one end of the coil spring 103. The lug 1025 is used to secure the fixing end 1041 of the webbing 104. The narrowing of one end of the semi-annular protrusions 1024 prevents the end of the coil spring 103, engaged in the gap 1026, from hooking onto the webbing 104. Figure 6 , 8 As shown in Figure 9, the webbing 104 is wound into a ring and fitted around the semi-circular protrusion 1024. The fixed end 1041 of the webbing 104 is fixed to the lug 1025, and the free end 1042 of the webbing 104 extends out from the gap 1014 of the side wall 1012.

[0044] like Figure 4 An embodiment of the coil spring 103 is shown, wherein the two ends of the coil spring 103 are respectively coiled up to be engaged in the cut 10131 of the base 101 and the gap 1026 of the reel 102, so that one end is fixed to the base 101, and the other end can be wound with the rotation of the reel 102 according to the applied external force, or move in the opposite direction under the tension of the coil spring 103 when the external force is removed.

[0045] The automatic webbing winding device 10 provided by this invention has a coil spring 103, one end of which is engaged in the cut 10131 of the base 101, and the other end of which is engaged in the gap 1026 of the winding reel 102. When no external force is applied to pull the webbing 104 outward, the webbing 104 is always in an automatic winding state under the action of the coil spring 103. When the webbing 104 is to be used, pulling the webbing 104 outward will cause the winding reel 102 to rotate in the forward direction, thereby winding the coil spring 103 and storing the winding force of the coil spring 103. When the external force is removed, under the tension of the coil spring 103, the coil spring 103 is driven to rotate in the reverse direction, and the winding reel 102 winds the webbing 104 onto the reel 102 one turn at a time, achieving the purpose of winding the webbing 104. The automatic webbing winding device 10 of the present invention can automatically wind up excess webbing 104 when it is not in use or during use, making it neater and more convenient, and also preventing the webbing 104 from being discarded and lost after being removed. In some embodiments, the forward direction can be clockwise, while the reverse direction can be counterclockwise, and vice versa.

[0046] like Figure 12As shown, a bedside bed 20 including the aforementioned automatic webbing winding device 10 is disclosed. The bedside bed 20 includes a base plate 202 and multiple side plates 201. The base plate 202 is generally parallel to the ground, and the multiple side plates 201 are generally perpendicular to the ground and surround the base plate 202. A webbing outlet 2011 is provided on each side plate 201. The automatic webbing winding device 10 is installed on the inner side of the side plate 201, and the free end 1042 of the webbing 104 passes through the webbing outlet 2011. In this embodiment, one automatic webbing winding device 10 is provided on each of the two side plates 201. The automatic webbing winding device 10 can be fixed to the inner side of the side plate 201 by a connection method generally used in the art, such as by screw connection or other methods. Optionally, the base of the automatic webbing winding device 10 can be integrally formed on the side plate 201, such as... Figure 5-7 As shown in Figures 10 and 11, the automatic webbing take-up device 10 also includes a locking member 107 disposed at the free end 1042 of the webbing 104. The locking member 107 includes a first locking member 1071 and a second locking member 1072, which, through their locking action, secure the free end of the webbing to a fixed point (not shown) near the bedside bed 20, such as the bed where the caregiver sleeps.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
