Description

Technical Field

[0001] This utility model relates to the field of household goods technology, and in particular to a bed that prevents pillows from falling off. Background Technology

[0002] In the fields of nursing beds or electric beds, a common design to improve the comfort and convenience of bedridden users is to divide the bed board into several relatively rotatable parts, such as a headboard and a footboard hinged to the headboard. The headboard can be raised and rotated using manual cranks, electric actuators, or motor-driven adjustment mechanisms to meet the user's needs for switching from a lying to a sitting position, facilitating activities such as eating, reading, or rehabilitation exercises.

[0003] However, such adjustable beds have a common problem in practical use: when lying flat, users usually need a pillow to support their head and neck, but when the headboard is raised and the user turns to a sitting position, the pillow often needs to be moved away. If the pillow is placed directly on the headboard surface, when the headboard is rotated upwards to an inclined angle, due to the lack of an effective fixing structure between the pillow and the board, the pillow is very likely to slide down the inclined board surface under the action of gravity. If the pillow falls to the ground, it will not only get dirty, but caregivers or the user will also need to bend down to pick it up, increasing the inconvenience and burden of care.

[0004] Therefore, existing adjustable beds need to be improved to solve the problem of pillows easily slipping off during position transitions.

[0005] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] One objective of this invention is to provide a pillow-preventing bed that can solve the problem of pillows easily slipping off during the transition of existing adjustable beds.

[0007] To achieve the above objectives, this utility model provides a pillow-prevention bed, comprising:

[0008] A bed board assembly, including a footboard and a headboard for placing pillows and hinged to the footboard;

[0009] The headboard assembly is located on the side of the headboard away from the footboard;

[0010] A flexible traction component, one end of which is connected to the headboard, and the other end of which is guided by the headboard assembly and connected to the pillow.

[0011] in,

[0012] When the headboard is rotated to tilt upwards away from the footboard, the headboard pulls the pillow toward the headboard assembly via the flexible traction member to prevent the pillow from falling downwards.

[0013] Optionally, the flexible traction element is a pull rope or an elastic band.

[0014] Optionally, the headboard includes:

[0015] The bed board body is hinged to the bed tailboard and is provided with a guide groove extending from the bed tailboard toward the headboard assembly;

[0016] A traction slider is slidably disposed in the guide groove for connecting with the flexible traction member;

[0017] A locking screw, threaded through the traction slider and abutting against the bed board body, restricts the relative sliding between the traction slider and the bed board body.

[0018] Optionally, the headboard assembly includes:

[0019] Bed screen body;

[0020] The L-shaped tube is installed in the headboard body and forms an L-shaped channel through which the flexible traction member passes.

[0021] Optionally, the headboard assembly includes:

[0022] A transverse tube, the first end of which is inserted into the headboard body, and the second end of which protrudes toward the headboard.

[0023] A longitudinal tube is located within the bed screen body, and its lower end is connected to the first end of the transverse tube.

[0024] Optionally, guide wheels are provided at the second end of the transverse pipe, the upper end of the longitudinal pipe, and the intersection of the transverse and longitudinal pipes.

[0025] Optionally, the top surface of the headboard body or the side surface of the headboard body near the headboard is provided with a through-hole for the flexible traction member to pass through.

[0026] The height of the insertion opening is higher than the height of the footboard.

[0027] Optional, also includes:

[0028] A pillow base, which is connected to the flexible traction member, is used to place and fix the pillow.

[0029] Optionally, the pillow seat is detachably connected to the pillow.

[0030] Optionally, the pillow base is magnetically connected to the pillow or attached via Velcro.

[0031] The beneficial effects of this utility model are as follows: It provides a pillow-prevention bed, and the working process is as follows:

[0032] Pillow lifting process: As the headboard rotates away from the headboard assembly and tilts upwards, the relative distance between it and the headboard assembly increases. This increases the first segment length of the flexible traction element from the headboard to the headboard assembly. Since the second segment length of the flexible traction element passing through the headboard assembly is fixed, and the total length of the flexible traction element remains essentially unchanged, the third segment length from the headboard assembly to the pillow is forced to shorten accordingly, thus generating a force that pulls the pillow towards the headboard assembly, preventing it from sliding down.

[0033] Pillow Settling Process: When the headboard rotates downwards to be flush with the footboard, the relative distance between it and the headboard assembly decreases. This shortens the first segment of the flexible traction component. Under the weight of the pillow itself, the third segment of the flexible traction component adaptively increases in length, and the pillow subsequently settles back onto the headboard surface.

[0034] Therefore, the anti-pillow-fall bed provided by this utility model can solve the problem of pillows easily slipping off during the transition of existing adjustable beds. Attached Figure Description

[0052] This invention provides a pillow-preventing bed that solves the problem of pillows easily slipping off during the transition of existing adjustable beds.

[0053] See Figure 1 and Figure 2 The anti-pillow-fall-off bedding provided in this embodiment includes:

[0054] The bed board assembly 1 includes a footboard 101 and a headboard 102 for placing a pillow 100 and hinged to the footboard 101;

[0055] The headboard assembly 2 is located on the side of the headboard 102 away from the footboard 101;

[0056] The flexible traction component 3 has one end connected to the headboard 102 and the other end connected to the pillow 100 after being guided by the headboard assembly 2.

[0057] in,

[0058] When the headboard 102 is rotated to tilt upwards away from the footboard 101, the headboard 102 pulls the pillow 100 toward the headboard assembly 2 via the flexible traction member 3 to prevent the pillow 100 from falling downwards.

[0059] It should be noted that the drive mechanism for rotating the headboard 102 can be a manual crank or an electric push rod, etc., and this embodiment does not limit it.

[0060] The core function of the anti-pillow-fall bed is that the rotation of the headboard 102 causes a dynamic redistribution of the length of different sections in the total path of the flexible traction component 3. The flexible traction rope is divided into three sections: the first section 301 runs from the headboard 102 to the headboard assembly 2, the second section 302 is located in the headboard assembly 2, and the third section 303 runs from the headboard assembly 2 to the pillow 100.

[0061] Pillow 100 lifting process: When the headboard 102 rotates away from the headboard assembly 2 and tilts upwards, the relative distance between it and the headboard assembly 2 increases. This increases the length of the first segment 301 of the flexible traction member 3 from the headboard 102 to the headboard assembly 2. Since the length of the second segment 302 of the flexible traction member 3 passing through the headboard assembly 2 is fixed, and the total length of the flexible traction member 3 remains essentially unchanged, the length of the third segment 303 from the headboard assembly 2 to the pillow 100 is forced to shorten accordingly, thereby generating a force that pulls the pillow 100 towards the headboard assembly 2, preventing it from sliding down.

[0062] The pillow 100 falling back down process: When the headboard 102 rotates downwards to be flush with the footboard 101, the relative distance between it and the headboard assembly 2 decreases. This shortens the length of the first segment 301 of the flexible traction member 3. Under the action of the pillow 100's own weight, the length of the third segment 303 of the flexible traction member 3 adaptively increases, and the pillow 100 falls back onto the surface of the headboard 102.

[0063] Therefore, the anti-pillow-fall bed provided by this utility model can solve the problem that the pillow 100 is easy to slip off during the state transition of existing adjustable beds.

[0064] In this embodiment, the flexible traction element 3 is a pull rope or an elastic band. When a pull rope is used, it acts as a non-stretchable flexible traction element 3, strictly adhering to the aforementioned length distribution principle. When an elastic band is used, the principle is the same, but the elasticity allows for a slight elastic contraction of the third segment 303 during the descent, making the movement gentler.

[0065] Optionally, the headboard 102 includes:

[0066] The bed board body 1021 is hinged to the bed tailboard 101 and is provided with a guide groove extending from the bed tailboard 101 toward the headboard assembly 2.

[0067] The traction slider 1022 is slidably disposed in the guide groove and is used to connect with the flexible traction member 3.

[0068] A locking screw 1023 is threaded through the traction slider 1022 and abuts against the bed board body 1021 to restrict the relative sliding between the traction slider 1022 and the bed board body 1021.

[0069] Loosening the locking screw 1023 allows adjustment of the position of the traction slider 1022, thereby adjusting the lifting height of the pillow 100. By adjusting the position of the traction slider 1022 in the guide groove, the relative distance between the fixed point of the flexible traction member 3 on the headboard 102 and the hinge axis is changed. This essentially pre-adjusts the initial value of the length of the first segment 301 of the flexible traction member 3, thus precisely controlling the change in the length of the third segment 303 when the headboard 102 rotates by the same angle, thereby adjusting the final lifting height of the pillow 100. This provides adjustable height for the pillow 100 to meet individual needs.

[0070] In this embodiment, the headboard assembly 2 includes:

[0071] Bed screen body 201;

[0072] L-shaped tube 202 is installed in the headboard body 201 and forms an L-shaped channel through which the flexible traction member 3 passes.

[0073] Furthermore, the headboard assembly 2 includes:

[0074] A transverse tube 2021, the first end of which is inserted into the headboard body 201, and the second end protruding toward the headboard 102;

[0075] The longitudinal tube 2022 is located inside the headboard body 201, and its lower end is connected to the first end of the transverse tube 2021.

[0076] Guide wheels 203 are provided at the second end of the transverse pipe 2021, the upper end of the longitudinal pipe 2022, and the intersection of the transverse pipe 2021 and the longitudinal pipe 2022.

[0077] The core function of the headboard assembly 2 is to form a low-friction, fixed-path guide mechanism. It ensures that the flexible traction element 3 slides smoothly inside and strictly limits the length of its second segment 302 within a constant channel, which is the basis for the reliable operation of the entire "three-segment length" model.

[0078] Furthermore, the top surface of the headboard body 201 or the side surface of the headboard body 201 near the headboard 102 is provided with a through-hole 2011 for the flexible traction member 3 to pass through; the position height of the through-hole 2011 is higher than the position height of the footboard 101, thereby ensuring that the flexible traction member 3 has a downward pulling angle when the headboard 102 is tilted, thus optimizing the lifting trajectory of the pillow 100.

[0079] In this embodiment, the anti-pillow-fall bedding also includes a pillow base 4, which is connected to the flexible traction member 3 and is used to hold and fix the pillow 100. Optionally, the pillow base 4 and the pillow 100 are detachably connected. For example, the pillow base 4 is magnetically connected to the pillow 100 or is attached by Velcro.

[0080] The pillow base 4 acts as a connector, smoothly transmitting the control effect of the flexible traction member 3 on the length of the third segment 303 to the pillow 100. Detachable connections (such as magnetic or Velcro) facilitate the removal, placement, and cleaning of the pillow 100 without affecting the flexible traction member 3 and the pillow base 4 themselves.

[0081] Of course, in some other embodiments, the pillow base 4 can be omitted, and the flexible traction member 3 can be directly fixed to the pillow 100 by knotting or fastening.

[0082] The anti-pillow-fall-off bed provided in this embodiment has the following advantages:

[0083] ① By connecting one end of the flexible traction member 3 to the rotatable headboard 102 and then guiding it through the headboard assembly 2 to the pillow 100, the length of each segment of the flexible traction member 3 is dynamically distributed by lifting and rotating the headboard 102, thus automatically preventing the pillow 100 from slipping during the state transition process.

[0084] ② By setting the bed board body 1021 with the guide groove, the sliding traction slider 1022 and the locking screw 1023, the lifting height of the pillow 100 in the tilted state can be flexibly adjusted to meet the personalized needs of different users.

[0085] ③ By setting a guide channel consisting of an L-shaped tube 202, a transverse tube 2021, and a longitudinal tube 2022 in the bed headboard assembly 2, and optionally equipping it with a guide wheel 203, a smooth and low-wear travel path is provided for the flexible traction component 3, which improves the system reliability and extends its service life.

[0086] ④ By setting up a pillow seat 4 connected to the flexible traction component 3, and configuring a detachable connection (such as magnetic or Velcro) between the pillow seat 4 and the pillow 100, the pillow 100 is stably and flatly supported, and the pillow 100 is conveniently put away and cleaned, thus improving the ease of use.

[0087] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
