Description

Technical Field

[0001] This utility model relates to the field of living furniture technology, and in particular to an easy-to-close bed frame. Background Technology

[0002] Storage beds typically use a pneumatic strut connection design, requiring users to overcome air pressure resistance to operate them: lifting them up utilizes pneumatic support to maintain the open position, while pressing them down requires overcoming air pressure resistance to return them to their original position. However, this conventional design suffers from a significant imbalance in operating force during actual use.

[0003] When the slatted frame is activated, the user can easily lift it up by using the reaction force of their feet on the ground and their arms.

[0004] However, during the closing phase, users can only rely on their own weight to press down, which is quite difficult for users with less strength (such as the elderly, children, or women). Especially when the slat frame is at the critical position between opening and closing, a great deal of force is required to overcome the critical resistance of the pneumatic rod and successfully close the slat frame, resulting in a very poor user experience.

[0005] Therefore, existing storage beds need to be improved to address the issue of requiring significant effort to close the slatted frame.

[0006] 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

[0007] One objective of this invention is to provide an easy-closing bed frame that effectively solves the problem that existing storage beds require considerable effort to close the slatted frame.

[0008] To achieve the above objectives, this utility model provides an easy-closing bed frame, comprising:

[0009] Bed frame;

[0010] A slatted frame, located at the top of the bed frame;

[0011] A pneumatic rod, one end of which is hinged to the bed frame and the other end of which is hinged to the slatted frame;

[0012] The counterweight unit includes a counterweight assembly fixed to the frame and a counterweight connecting rod hinged to the counterweight assembly and the pneumatic rod.

[0013] The pneumatic rod has a retracted state that keeps the slatted frame closed relative to the bed frame, and an extended state that keeps the slatted frame open relative to the bed frame.

[0014] The counterweight assembly is used to generate additional downward pressure on the frame through its own gravity, thereby reducing the operating force required for the pneumatic rod to switch from the extended state to the retracted state.

[0015] Optionally, the pneumatic rod includes:

[0016] A guide sleeve, one end of which is hinged to the frame;

[0017] A telescopic rod, one end of which is hinged to the bed frame, and the other end of which is slidably inserted into the other end of the guide sleeve;

[0018] The counterweight link is hinged to the middle of the guide sleeve.

[0019] Optionally, the counterweight assembly includes:

[0020] A counterweight sleeve is fixed to the frame and has an inner cavity with an opening facing the pneumatic rod.

[0021] A counterweight, wherein the counterweight is located in the inner cavity of the sleeve;

[0022] The counterweight connector has one end that slides into the inner cavity of the sleeve, and the other end that extends outward through the opening of the inner cavity of the sleeve and is hinged to the counterweight connecting rod.

[0023] Optionally, a compression spring is provided between the counterweight and the counterweight joint.

[0024] Optionally, the counterweight connector has a connector spring positioning groove on its end face near the compression spring for the compression spring to be inserted.

[0025] Optionally, the counterweight block has a counterweight spring positioning groove on its end face near the compression spring for the compression spring to be inserted.

[0026] Optionally, the density of the counterweight is greater than the density of the slatted frame.

[0027] Optionally, the counterweight may be a cast iron block, a steel block, a lead block, or a concrete block.

[0028] Optional, also includes:

[0029] A linkage assembly, one end of which is connected to the end of the bed frame near the headboard, and the other end of which is connected to the end of the slatted frame near the headboard;

[0030] in,

[0031] When the pneumatic rod is in the extended state, the frame is tilted upward from the head of the bed to the foot of the bed, and the pneumatic rod is tilted downward from top to bottom towards the foot of the bed.

[0032] The connecting rod assembly, the pneumatic rod, and the counterweight unit are arranged sequentially from the head of the bed to the foot of the bed.

[0033] Optionally, the bed frame surrounds a storage cavity, and the storage cavity is provided with a partition that divides the storage cavity into several sub-cavities.

[0034] The beneficial effects of this invention are as follows: It provides an easy-to-close bed frame. The counterweight unit is connected to the slatted frame via a counterweight linkage. When the user presses down on the bed frame, the weight of the counterweight component is converted into additional downward force, which, together with the user's applied force, counteracts the supporting force of the gas spring. This design provides a significant assist effect, making the closing action, which originally required considerable force, much easier. Especially for users with less strength, the assistance of the counterweight unit can significantly reduce the difficulty of operation, making the closing action smoother and less strenuous.

[0035] Furthermore, the counterweight linkage is designed to provide support to the counterweight assembly using a pneumatic rod when the slat frame is in the open state, thereby maintaining the open state of the slat frame and preventing it from automatically falling back and closing due to excessive gravity of the counterweight assembly when the slat frame is in the open state.

[0036] Therefore, the easy-closing bed frame provided by this utility model can effectively solve the problem that existing storage beds require a lot of effort to close the slatted frame. Attached Figure Description

For those skilled in the art to which this utility model pertains, the specific meaning of the above terms in the embodiments of this utility model can be understood according to the specific circumstances.

[0054] The easy-closing bed frame provided by this utility model cleverly utilizes gravity to assist in the closing operation of the slatted frame by adding a counterweight unit to the slatted frame, thereby effectively solving the problem of the difficulty in closing the slatted frame of existing storage beds.

[0055] See Figure 1 This utility model provides an easy-close bed frame, including a bed frame 1, a slatted frame 2, a gas spring 3, and a counterweight unit 4.

[0056] The slatted frame 2 is located at the top of the bed frame 1; one end of the gas spring 3 is hinged to the bed frame 1, and the other end is hinged to the slatted frame 2; see also Figure 2The counterweight unit 4 includes a counterweight assembly 401 fixed to the frame 2 and a counterweight connecting rod 402 hinged to the counterweight assembly 401 and the pneumatic rod 3.

[0057] The pneumatic rod 3 has a retracted state that keeps the slatted frame 2 closed relative to the bed frame 1, and an extended state that keeps the slatted frame 2 open relative to the bed frame 1.

[0058] The counterweight component 401 is used to generate additional downward pressure on the frame 2 through its own gravity, so as to reduce the operating force required for the pneumatic rod 3 to switch from the extended state to the retracted state.

[0059] The core principle of the easy-close bed frame provided in this embodiment lies in the fact that the counterweight unit 4 is connected to the slatted frame 2 via the counterweight connecting rod 402. When the user presses down on the bed frame, the weight of the counterweight component 401 is converted into additional downward force, which, together with the external force applied by the user, counteracts the supporting force of the gas spring 3. This design provides a significant assist effect, making the closing action, which originally required considerable force, much easier. Especially for users with less strength, the assistance of the counterweight unit 4 can significantly reduce the difficulty of operation, making the closing action smoother and less strenuous.

[0060] Furthermore, the counterweight linkage 402 is designed to provide support to the counterweight assembly 401 using the pneumatic rod 3 when the slat frame 2 is in the open state, thereby maintaining the open state of the slat frame 2 and preventing the slat frame 2 from automatically falling back and closing due to excessive gravity of the counterweight assembly 401 when it is in the open state.

[0061] Therefore, the easy-closing bed frame provided by this utility model can effectively solve the problem that existing storage beds require a lot of effort to close the slat frame 2.

[0062] In this embodiment, the pneumatic rod 3 includes a guide sleeve 301 and a telescopic rod 302. One end of the guide sleeve 301 is hinged to the frame 2; one end of the telescopic rod 302 is hinged to the bed frame 1, and the other end of the telescopic rod 302 is slidably inserted into the other end of the guide sleeve 301; wherein, the counterweight connecting rod 402 is hinged to the middle position of the guide sleeve 301. Hinging the counterweight connecting rod 402 to the middle of the guide sleeve 301 instead of the telescopic rod 302 avoids interference of the counterweight connecting rod 402 with the sliding movement of the telescopic rod 302, ensuring the smoothness of the telescopic movement of the pneumatic rod 3.

[0063] In this embodiment, the counterweight assembly 401 includes a counterweight sleeve 4011, a counterweight block 4012, a counterweight connector 4013, and a compression spring 4014.

[0064] The counterweight sleeve 4011 is fixed to the frame 2, and the counterweight sleeve 4011 has an inner cavity with an opening facing the pneumatic rod 3; the counterweight block 4012 is located in the inner cavity of the sleeve; one end of the counterweight connector 4013 is slidably inserted into the inner cavity of the sleeve, and the other end extends outward through the opening of the inner cavity of the sleeve and is hinged to the counterweight connecting rod 402. A compression spring 4014 is located between the counterweight block 4012 and the counterweight connector 4013, and is used to drive the counterweight connector 4013 to press against the counterweight connecting rod 402, so as to provide sufficient support force for the counterweight assembly 401 when the frame 2 is opened.

[0065] The counterweight 4012 is a key component providing additional downward pressure to the frame 2. It can be made of a high-density material (with a density greater than that of the frame 2), such as cast iron, steel, lead, or concrete. The high density of the counterweight 4012 allows for maximum counterweight effect within a limited space, avoiding excessive increase in the volume of the frame 2 due to added weight. The choice of different materials such as cast iron, steel, lead, or concrete provides diverse solutions to meet the positioning requirements of different products. For example, cast iron and steel offer high durability, lead blocks are smaller, and concrete is less expensive.

[0066] The counterweight connector 4013 is designed to allow the counterweight assembly 401 to extend and retract in conjunction with the opening and closing of the frame 2. When the frame 2 is open, the counterweight connector 4013 slides outward relative to the counterweight sleeve 4011 under the drive of the compression spring 4014, so that the counterweight connecting rod 402 abuts against the pneumatic rod 3. When the frame 2 is closed, the hand pulls down on the frame 2, and the pneumatic rod 3 gradually retracts, thereby applying a pushing force to the counterweight connecting rod 402, so that the counterweight connector 4013 overcomes the elastic force of the compression spring 4014 and slides inward relative to the counterweight sleeve 4011, so as to cooperate with the smooth retraction of the pneumatic rod 3.

[0067] Optionally, the counterweight connector 4013 has a connector spring positioning groove 4013a on its end face near the compression spring 4014 for the compression spring 4014 to be inserted. The counterweight block 4012 has a counterweight spring positioning groove 4012a on its end face near the compression spring 4014 for the compression spring 4014 to be inserted.

[0068] The spring positioning groove design ensures that the counterweight connector 4013 and counterweight 4012 maintain precise alignment with the compression spring 4014, preventing off-center wear and improving system stability. The spring positioning grooves at the connector and counterweight 4012 ends not only prevent spring displacement and failure but also simplify the assembly process, making installation more convenient. The double-end fixing design further extends the spring's service life, ensuring the durability and reliability of the assist effect.

[0069] Furthermore, regarding the movement of the counterweight 4012 within the sleeve cavity, two designs are possible: non-sliding and sliding.

[0070] (1) Non-sliding design

[0071] The counterweight 4012 is always located at the bottom of the inner cavity of the sleeve and will not slide inside the inner cavity of the sleeve. For example, the counterweight 4012 is glued and fixed to the bottom of the inner cavity of the sleeve, or the weight of the counterweight 4012 is small, and under the squeezing action of the compression spring 4014, it always abuts against the bottom of the inner cavity of the sleeve in order to achieve the maximum leverage and effort-saving effect.

[0072] (2) Sliding design

[0073] The counterweight 4012 can slide within the inner cavity of the sleeve for a certain distance. Specifically, when the frame 2 is in the open state, the entire frame 2 is tilted upwards towards the foot of the bed. Therefore, the inner cavity of the sleeve is also tilted upwards towards the foot of the bed. At this time, as long as the component of gravity of the counterweight 4012 along the axis of the compression spring 4014 is sufficient to overcome the elastic force of the compression spring 4014, the counterweight 4012 can slide down appropriately along the inner cavity of the sleeve under its own gravity and squeeze the compression spring 4014, forcing the counterweight connecting rod 402 to press against the pneumatic rod 3 to prevent the pneumatic rod 3 from retracting, thereby maintaining the open state of the frame 2.

[0074] When the user closes the slat frame 2, the slat frame 2 drives the counterweight sleeve 4011 to gradually return to a horizontal position. The gravitational component of the counterweight block 4012 along the axis of the compression spring 4014 gradually decreases. Under the elastic force of the compression spring 4014, the counterweight block 4012 gradually moves towards the bottom of the sleeve cavity. At this time, the counterweight block can gradually provide a larger gravitational component, making it easier for the user to press down the slat frame 2. Finally, it is pushed by the compression spring 4014 to abut against the bottom of the sleeve cavity, thereby avoiding the abnormal noise problem caused by the random shaking of the counterweight block 4012.

[0075] Optionally, the easy-close bed frame also includes a linkage assembly 5 to ensure the determinacy of the movement path during the opening and closing of the frame 2.

[0076] One end of the linkage assembly 5 is connected to the bed frame 1, and the other end is connected to the slatted frame 2. Further, the linkage assembly 5 can be a pure linkage structure or a pneumatic linkage structure. A pure linkage structure enhances the rigidity of the system, preventing lateral swaying of the slatted frame 2 during opening and closing, thus improving stability; while the pneumatic linkage can assist in sharing the supporting force, forming a graded assistance system with the pneumatic rod 3, which is particularly suitable for large-size bed frames, making opening and closing operations more effortless and smooth. This flexible design can adapt to the needs of different users, improving the product's applicability and practicality. This embodiment does not limit the number or composition of the linkage assembly 5.

[0077] In this configuration, when the pneumatic rod 3 is in the extended state, the frame 2 is tilted upwards from the head of the bed towards the foot of the bed, and the pneumatic rod 3 tilts downwards towards the foot of the bed. The connecting rod assembly 5, the pneumatic rod 3, and the counterweight unit 4 are arranged sequentially from the head of the bed towards the foot of the bed. This structural design facilitates convenient opening and closing of the frame at the foot of the bed and provides a good counterweight and labor-saving effect. Specifically, when the frame 2 is open, it is tilted with the head of the bed lower and the foot of the bed higher, and the pneumatic rod 3 tilts downwards towards the foot of the bed. This layout allows:

[0078] ① The direction of gravity of counterweight 4012 partially coincides with the direction of movement of the closed frame 2, and the gravity component directly assists in pressing down;

[0079] ② The supporting force of the pneumatic rod 3 is balanced with the tension of the counterweight connecting rod 402 to prevent the counterweight from pressing back into the frame 2 too early, while ensuring maximum assistance when closed.

[0080] In this embodiment, the bed frame 1 surrounds and forms a storage cavity 101, and the storage cavity 101 is provided with a divider 102 that divides the storage cavity 101 into several sub-cavities. Dividing the storage cavity 101 into several sub-cavities not only facilitates classified storage and improves space utilization, but also acts as a reinforcing rib to enhance the overall structural strength of the bed frame 1. In addition, the sub-cavity design can prevent the stored items from colliding and making noise during movement, optimizing the user experience, while making the storage more organized and improving the practicality and functionality of the product.

[0081] In summary, the easy-close bed frame provided in this embodiment has the following advantages:

[0082] ① By adding a counterweight unit 4, gravity assists in pressing down, effectively reducing the operating force required to close the slat frame 2, thus solving the problem of the difficulty in closing traditional storage beds.

[0083] ② The counterweight connecting rod 402 is hinged to the middle of the guide sleeve 301 of the pneumatic rod 3 to avoid interfering with the movement of the telescopic rod 302 and to ensure the smooth operation of the pneumatic rod 3.

[0084] ③ The counterweight joint 4013 and the compression spring 4014 are linked, so that the counterweight component 401 adapts to the opening and closing of the frame 2, and balances the support and assist functions.

[0085] 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.
