Description

Technical Field

[0001] This utility model relates to the field of flip tables, and more particularly to a flip table for ships with a locking mechanism. Background Technology

[0002] Currently, to prevent the increased safety risks associated with marine furniture due to the swaying of the ship during navigation, furniture is often fixed to the wall panels or the ground. To reduce usage risks and improve space utilization, existing technology includes a sliding folding table for ships, such as Chinese Patent Application No. CN202421609041.6. This table includes a slide rail installed on the side wall of the hull, a slider slidably connected to the slide rail, a sliding frame connected to the slider, and a tabletop hinged to the bottom of the sliding frame. A magnetic latch is provided between the tabletop and the sliding frame to achieve folding and storage of the tabletop. A buffer support assembly is provided between the tabletop and the sliding frame to achieve downward flipping of the tabletop.

[0003] The existing technology, similar to the above-mentioned patent, has the following technical problems: In the existing technology, the buffer support component (guide rod and sliding block) only relies on the sliding block to reach the bottom position for limitation, but there is no locking mechanism. It cannot resist inertia or forces from bottom to top. For example, if the table is hit from below, or if the table loses weight when the hull moves downward, the table may be lifted up instantly.

[0004] Therefore, there is an urgent need for a shipboard flip table with a locking mechanism to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the problem that existing buffer support components (guide rod and sliding block) rely solely on the sliding block reaching the bottom for position limiting, but lack a locking mechanism, this utility model proposes a ship-mounted flip table with a locking mechanism. The technical solution is as follows:

[0006] A shipboard flip table with a locking mechanism includes a pair of parallel guide rails fixed to a vertical mounting surface, and a tabletop with one end hinged to the mounting surface via a hinge mechanism, allowing the tabletop to flip up and down relative to the mounting surface.

[0007] A linkage support mechanism is provided between the top surface of the tabletop and the guide rail, so that the tabletop is coplanar with or perpendicular to the mounting surface; and a fixing mechanism is provided on the mounting surface to fix the tabletop in a state of being coplanar with the mounting surface.

[0008] A first locking plate is provided on the bottom surface of the tabletop near the hinge mechanism, and a second locking plate is provided on the mounting surface. The first locking plate and the second locking plate are parallel to each other and staggered from each other, and both are perpendicular to the mounting surface and the tabletop. A pop-out piece is embedded on one side of the second locking plate, and a locking groove for cooperating with the pop-out piece is provided on one side of the first locking plate. When the tabletop is flipped to be perpendicular to the mounting surface, the pop-out piece is inserted into the locking groove to lock the tabletop. The second locking plate is also provided with a release mechanism, which can retract the pop-out piece into the second locking plate, thereby releasing the tabletop.

[0009] Furthermore, the linkage support mechanism includes a slider mounted on a guide rail, a connecting rod between the slider and the table, one end of the connecting rod being rotatably connected to the top surface of the slider, and the other end being rotatably connected to the top surface of the table. A limit block is provided on the guide rail to limit the slider, so that the table can be rotated to a state perpendicular to the mounting surface at most.

[0010] Furthermore, a damper is provided on the limiting block to buffer the slider.

[0011] Furthermore, the fixing mechanism includes a locking post vertically installed on the mounting surface. A clearance channel is provided on the tabletop corresponding to the position of the locking post. When the tabletop is flipped upward to a state parallel to the mounting surface, the locking post protrudes from the bottom surface of the tabletop through the clearance channel. The part of the locking post protruding from the bottom surface of the tabletop has a transverse locking hole, into which an external lock can be inserted to fix the tabletop.

[0012] Furthermore, the second locking plate has a movable hole. The pop-out component includes a spring pin placed in the movable hole and a spring coaxially connected to the spring pin. One end of the spring is fixedly connected to the spring pin, and the other end abuts against the inner end face of the movable hole. The opening of the movable hole is provided with an anti-disengagement baffle. The baffle has a protruding channel with a diameter smaller than the movable hole. The outer periphery of the spring pin is provided with an anti-disengagement protrusion, so that the spring pin can only partially protrude from the protruding channel. The protruding end of the spring pin is provided with a slope. When the table is flipped, the first locking plate uses the slope to press the spring pin back into the movable hole. When the table is flipped into place, the spring pin pops out under the action of the spring and inserts into the locking groove.

[0013] Furthermore, the release mechanism includes an active channel coaxially opened on the inner end face of the active hole, and the active channel extends to the outside of the second locking plate. The diameter of the active channel is smaller than the diameter of the active hole, and an active rod is coaxially inserted inside the active channel. One end of the active rod is coaxially fixedly connected to the end of the spring pin located inside the active hole, and the other end is located outside the active hole. A handle is provided at the end of the active rod located outside the second locking plate.

[0014] Furthermore, a limiting groove is provided along the axis of the channel opening near the outer side of the movable channel. The limiting groove extends along the channel opening into the movable channel. A limiting protrusion is provided on the movable rod body. The limiting protrusion can slide in the limiting groove. After the limiting protrusion is pulled out of the limiting groove and rotated, the channel opening of the movable channel can lock the limiting protrusion to prevent the spring pin from resetting.

[0015] Furthermore, the first locking plate has a right-angled triangle cross-section, with one right-angled side located on the tabletop and the other right-angled side abutting against the mounting surface when the tabletop is flipped to be perpendicular to the mounting surface.

[0016] The beneficial effects of this utility model are as follows: when the table is flipped to the working position (perpendicular to the mounting surface), automatic locking is achieved through the cooperation of the pop-out part and the locking groove. In addition, the first locking plate also disperses the stress received by the linkage support mechanism, which enhances the stability and load-bearing safety of the table in the swaying environment of the ship, and fundamentally avoids the risk of rebound, shaking or accidental closure that may exist when relying solely on limit blocks or dampers.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figure 1 , Figure 2 As shown, a shipboard flip table with a locking mechanism includes a pair of parallel guide rails 2, which are fixed to a vertical mounting surface 1. It also includes a tabletop 3, one end of which is hinged to the mounting surface 1 via a hinge mechanism, so that the tabletop 3 can flip up and down relative to the mounting surface 1.

[0025] like Figure 1 As shown, a linkage support mechanism is provided between the top surface of the tabletop 3 and the guide rail 2, so that the tabletop 3 is coplanar with or perpendicular to the mounting surface 1; and the mounting surface 1 is provided with a fixing mechanism, which can fix the tabletop 3 in a state coplanar with the mounting surface 1.

[0026] like Figure 2 , Figure 4 , Figure 5 As shown, a first locking plate 4 is provided on the bottom surface of the tabletop 3 near the hinge mechanism, and a second locking plate 5 is provided on the mounting surface 1. The first locking plate 4 and the second locking plate 5 are parallel to each other and staggered from each other, and are both perpendicular to the mounting surface 1 and the tabletop 3. A pop-out piece is embedded on one side of the second locking plate 5, and a locking groove 8 that matches the pop-out piece is provided on one side of the first locking plate 4. When the tabletop 3 is flipped to be perpendicular to the mounting surface 1, the pop-out piece is inserted into the locking groove 8 to lock the tabletop 3. The second locking plate 5 is also provided with a release mechanism, which can retract the pop-out piece into the second locking plate 5, thereby releasing the tabletop 3.

[0027] like Figure 1 , Figure 2 , Figure 3 As shown, preferably, the linkage support mechanism includes a slider 13 disposed on the guide rail 2, and a connecting rod 14 disposed between the slider 13 and the table 3. One end of the connecting rod 14 is rotatably connected to the top surface of the slider 13, and the other end is rotatably connected to the top surface of the table 3. A limit block 15 is disposed on the guide rail 2, and the limit block 15 limits the slider 13 so that the table 3 can be rotated to be perpendicular to the mounting surface 1 at most.

[0028] like Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, preferably, the second locking plate 5 has a movable hole 20. The pop-out component includes a spring pin 6 placed in the movable hole 20 and a spring 7 coaxially connected to the spring pin 6. One end of the spring 7 is fixedly connected to the spring pin 6, and the other end abuts against the inner end face of the movable hole 20. The opening of the movable hole 20 is provided with an anti-disengagement baffle 22. The baffle has a protruding channel 23 with a diameter smaller than that of the movable hole 20. The outer periphery of the spring pin 6 is provided with an anti-disengagement protrusion 24, so that the spring pin 6 can only partially protrude from the protruding channel 23. The protruding end of the spring pin 6 is provided with a slope 25. When the table 3 is flipped, the first locking plate 4 uses the slope 25 to press the spring pin 6 back into the movable hole 20. When the table 3 is flipped into place, the spring pin 6 pops out under the action of the spring 7 and inserts into the locking groove 8. This design achieves automatic locking. The slope 25 at the front end of the spring pin 6 allows the spring pin 6 to be smoothly compressed during the flipping of the table 3. Once aligned with the locking groove 8, the preload of the spring 7 can immediately drive the spring pin 6 to pop out and complete the automatic locking.

[0029] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, preferably, the release mechanism includes a movable channel 21 coaxially opened on the inner end face of the movable hole 20, and the movable channel 21 extends to the outside of the second locking plate 5. The diameter of the movable channel 21 is smaller than the diameter of the movable hole 20, and a movable rod 9 is coaxially inserted inside the movable channel 21. One end of the movable rod 9 is coaxially fixedly connected to the end of the spring pin 6 located inside the movable hole 20, and the other end is located outside the movable hole 20. A handle 10 is provided at the end of the movable rod 9 located outside the second locking plate 5. The release mechanism provides a convenient unlocking method. The user can overcome the spring force by pulling the handle 10 outward, retract the spring pin 6, thereby unlocking the tabletop 3 and making the operation simple and effortless.

[0030] like Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, preferably, the movable channel 21 has a limiting groove 12 along its axis near the outer opening. The limiting groove 12 extends into the movable channel 21. A limiting protrusion 11 is provided on the body of the movable rod 9. The limiting protrusion 11 can slide in the limiting groove 12. After pulling the limiting protrusion 11 out of the limiting groove 12, the handle 10 is rotated to make the limiting protrusion 11 rotate away from the axis of the limiting groove 12. Then, the handle 10 is released, and the opening of the movable channel 21 can lock the limiting protrusion 11, preventing the spring pin 6 from resetting. When the movable rod 9 is pulled out to unlock, the limiting protrusion 11 is locked in the opening by rotation, which can prevent the spring pin 6 from accidentally resetting under the action of the spring 7. If the spring pin 6 needs to be reset, the handle 10 is rotated to align the limiting protrusion with the limiting groove 12, and then the handle 10 is released to complete the reset. This allows users to freely operate the tabletop 3 to flip after unlocking without having to continuously pull on the handle 10, improving both ease of operation and safety.

[0031] like Figure 1 , Figure 3 As shown, preferably, the linkage support mechanism includes a slider 13 mounted on the guide rail 2. A connecting rod 14 is provided between the slider 13 and the tabletop 3. One end of the connecting rod 14 is rotatably connected to the top surface of the slider 13, and the other end is rotatably connected to the top surface of the tabletop 3. A limit block 15 is provided on the guide rail 2 to limit the slider 13, allowing the tabletop 3 to rotate to a position perpendicular to the mounting surface 1. Preferably, a damper 16 is provided on the limit block 15 to buffer the slider 13. The linkage support mechanism converts the rotation motion of the tabletop 3 into the linear motion of the slider 13, ensuring the smoothness and controllability of the tabletop 3's trajectory during rotation. The limit block 15 provides mechanical limitation, working in conjunction with the subsequent locking mechanism to ensure that the tabletop 3 can accurately and stably remain in the horizontal working position.

[0032] like Figure 1 , Figure 2 As shown, preferably, the fixing mechanism includes a locking post 17 vertically mounted on the mounting surface 1. A clearance channel 18 is provided on the tabletop 3 corresponding to the locking post 17. When the tabletop 3 is flipped upwards to a state parallel to the mounting surface 1, the locking post 17 protrudes from the bottom surface of the tabletop 3 through the clearance channel 18. A transverse locking hole 19 is provided on the portion of the locking post 17 protruding from the bottom surface of the tabletop 3, allowing an external lock to be inserted into the locking hole 19 to fix the tabletop 3. The fixing mechanism is specifically designed for fixing the tabletop 3 in its vertically retracted state. When the tabletop 3 is retracted, it is completely locked, preventing accidental opening during ship turbulence and enhancing safety and reliability in the retracted state.

[0033] like Figure 3As shown, preferably, the first locking plate 4 has a right-angled triangle cross-section, with one right-angled side located on the tabletop 3, and the other right-angled side abutting against the mounting surface 1 when the tabletop 3 is flipped to be perpendicular to the mounting surface 1. This shape design is not only used for installation and locking, but also provides an additional support surface when the tabletop 3 is flipped to the horizontal position. Its right-angled side is in close contact with the mounting surface 1, which can effectively share and bear the vertical load on the tabletop 3. Working in conjunction with the locking mechanism, it greatly enhances the structural strength and stability of the tabletop 3 in the working state.

[0034] The method of using this utility model is as follows:

[0035] 1. Unfolding the table: When it is necessary to unfold the table 3, first unlock the lock on the locking pin 17 (an ordinary padlock will do), then flip the table 3 downwards after unlocking it. The linkage support mechanism guides its smooth movement, and the limit block 15 and damper 16 buffer and limit its final position.

[0036] 2. Locking: When the tabletop 3 is flipped to the horizontal working state, the spring pin 6 of the locking mechanism will automatically spring into the locking groove 8 of the first locking plate 4 under the action of the spring 7, and complete the automatic locking. At the same time, the right-angle structure of the first locking plate 4 provides additional support to ensure that the tabletop 3 can bear the load stably.

[0037] 3. Folding up the table: After use, pull and rotate the handle 10 again to keep the limit protrusion 11 locked in the channel opening and in the unlocked state. The table 3 can then be flipped up to the vertical position. At this time, the locking pin 17 protrudes from the clearance channel 18 and can be fixed by inserting an external lock into the lock hole 19 to prevent the table 3 from being accidentally opened due to the ship's turbulence.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
