Description

Technical Field

[0001] This invention relates to the field of lock technology, and more particularly to a baby carrier lock for an aircraft lavatory. Background Technology

[0002] To meet the needs of different passenger groups, aircraft lavatories are equipped with baby carriers, providing a temporary platform for infants. When not in use, the baby carrier rests against the lavatory side wall and features a foldable design, allowing it to be unfolded or folded up as needed. This device provides passengers with convenient and safe care for their infants. The baby carrier is secured to the side wall by a latch 41. When in use, the latch needs to be opened to lower the baby carrier, and after use, the baby carrier needs to be folded against the side wall and locked in place using the latch. However, opening the latch often requires both hands, which is inconvenient for passengers holding infants. Furthermore, traditional latches do not securely fasten the baby carrier, causing vibrations and noises between the baby carrier and the side wall when the aircraft encounters turbulence during flight. The continuous vibrations during turbulence can also easily damage the latch. Summary of the Invention

[0003] Purpose of the invention: This invention provides a baby carrier lock for aircraft lavatories that can be opened with one hand and prevents the baby carrier from vibrating, thereby improving ease of use and service life.

[0004] Technical solution: A baby carrier lock for an aircraft lavatory includes an opening mechanism, an inner cover, a locking mechanism, and a hook mechanism. The inner cover has a groove on one side, and the opening mechanism is located within the groove. The upper surface of the inner cover is positioned at a lock opening, and the locking mechanism is located within and movably connected to the lock opening. The groove communicates with the lock opening, and the opening mechanism and the locking mechanism are connected within the groove. The upper end of the locking mechanism is connected to the hook mechanism. A touch-activated opening mechanism drives the locking mechanism to move, causing the locking mechanism and the hook mechanism to engage or disengage.

[0005] Furthermore, the opening mechanism includes an opening handle, a handle shaft, and a torsion spring. A touch rod is provided on the upper end of the opening handle and the side that is connected to the locking mechanism. The handle shaft is horizontally positioned across the top of the groove. The torsion spring is sleeved on the handle shaft. The opening handle is rotatably connected to the inner cover plate through the handle shaft. One end of the torsion spring is fixedly connected to the inner cover plate, and the other end is fixedly connected to the opening handle. The touch rod is connected to the locking mechanism.

[0006] Furthermore, the locking mechanism includes a spring, a latch bar, a locking bar, and a locking bar pivot. The latch bar is disposed within and movably connected to the lock opening. The lower end of the latch bar is fitted with the spring, and the lower end of the spring abuts against the inner cover plate. Both the lock opening and the upper end of the latch bar are provided with connecting holes, which are located on the same side. The locking bar pivot is disposed within each of the two connecting holes. One end of the locking bar is movably connected to the lock opening via the locking bar pivot, and the other end of the locking bar is movably connected to the latch bar via the locking bar pivot.

[0007] Furthermore, the upper end of the latch bar and the opening mechanism on opposite sides is chamfered.

[0008] Furthermore, the locking mechanism includes a buckle and a shock-absorbing device. The shock-absorbing device is located at the lower end of the buckle and is fixedly connected thereto. The upper end of the buckle is connected to the locking mechanism.

[0009] Furthermore, the shock-absorbing device is a shock-absorbing pad.

[0010] Furthermore, the bracket lock also includes an outer cover plate, which is disposed on the opening mechanism side of the inner cover plate.

[0011] Beneficial effects: The advantages of this invention are that by using the opening mechanism, inner cover plate, locking mechanism and hook mechanism in combination, the opening mechanism can be pulled with one hand to open the baby carrier lock, which improves the convenience of use. Moreover, the hook mechanism provides resistance to the baby carrier after folding, making the baby carrier installation more stable, reducing noise and vibration, and extending the service life of the baby carrier lock.

[0019] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0020] A type of baby carrier lock for airplane lavatories, such as Figure 1-6 As shown, the device includes an opening mechanism 1, an inner cover plate 2, a locking mechanism 3, and a hook mechanism 4. The inner cover plate 2 has a groove 21 on one side, and the opening mechanism 1 is located within this groove 21. The opening mechanism 1 and the inner cover plate 2 are flush, making the entire baby carrier lock a single unit. The upper surface of the inner cover plate 2 has a locking opening 22, which communicates with the groove 21. The locking mechanism 3 is located within and movably connected to the locking opening 22. This movable connection means that the locking mechanism 3 can move up and down within the locking opening 22. The opening mechanism 1 and the locking mechanism 3 are connected within the groove 21. This means that the opening mechanism 1 controls the operation of the locking mechanism 3; when the opening mechanism 1 is moved, it touches the locking mechanism 3, causing the locking mechanism 3 to activate. The locking mechanism 3 moves up and down to operate. The upper end of the locking mechanism 3 is connected to the locking hook mechanism 4. It can be understood that the locking mechanism 3 completes the locking by connecting with the locking hook mechanism 4. That is, when the locking mechanism 3 extends upward, it will be locked with the locking hook mechanism 4. When the locking mechanism 3 retracts downward, it will disengage from the locking hook mechanism 4. The baby carrier lock also includes an outer cover plate 5 and an inner cover plate 2 located inside one side of the outer cover plate 5. The upper end of the locking mechanism 3 extends from the upper surface of the outer cover plate 5. The outer cover plate 5 is the carrier of the inner cover plate 2. The outer cover plate 5 is installed in the bracket first, and then the inner cover plate 2 is placed inside the outer cover plate 5, making the inner cover plate 2 easier to install and easier to replace if the inner cover plate 2 is damaged later.

[0021] The opening mechanism 1 includes an opening handle 11, a handle shaft 12, and a torsion spring 13. A contact rod 14 is provided on the upper end of the opening handle 11, on the side where it connects with the locking mechanism 3; that is, a contact rod 14 is provided on one side within the groove 21. The handle shaft 12 is horizontally positioned across the top of the groove 21, and a torsion spring 13 is fitted onto the handle shaft 12. The opening handle 11 is rotatably connected to the inner cover plate 2 via the handle shaft 12; that is, the opening handle 11 is connected to the inner cover plate 2 at the upper end of the inner cover plate 2 via the handle shaft 12. After connection, the opening handle 11 can rotate around the handle shaft 12. Moving the opening handle 11 from its lower end to its upper end... Rotating around the handle shaft 12, one end of the torsion spring 13 is fixedly connected to the inner cover plate 2, and the other end is fixedly connected to the opening handle 11. It can be understood that the function of the torsion spring 13 is to pull the opening handle 11 towards the inner cover plate 2 when the opening handle 11 is in the normal state, so that the opening handle 11 is in the closed state. When the opening handle 11 is pulled, the opening handle 11 is pulled back to reset by the pulling force of the torsion spring 13. The touch rod 14 is connected to the locking mechanism 3. It can be understood that when the opening handle 11 is pulled, the touch rod 14 will contact the locking mechanism 3 and press the locking mechanism 3 down, controlling the locking mechanism 3 to open.

[0022] The locking mechanism 3 includes a spring 31, a latch bar 32, a locking bar 33, and a locking bar pivot 34. The latch bar 32 is located inside and movably connected to the lock opening 22, meaning it can move up and down within the lock opening 22. A spring 31 is fitted onto the lower end of the latch bar 32, and the lower end of the spring 31 abuts against the inner cover plate 2. This abutting connection provides an upward force to the latch bar 32, keeping it in contact with the locking hook mechanism 4. Both the lock opening 22 and the upper end of the latch bar 32 have connecting holes 35 located on the same side. A locking bar pivot 34 is installed within each of the two connecting holes 35. One end of the locking bar 33 passes through a lock on the lock opening 22. The lever shaft 34 is movably connected to it, and the other end of the locking lever 33 is movably connected to it via the locking lever shaft 34 on the latch lever 32. The function of setting the locking lever 33 is to restrict the latch lever 32, so that the latch lever 32 moves within a certain range and prevents the latch lever 32 from being ejected by the spring 31. This restrictive setting is relatively easy to install. The upper end of the latch lever 32 opposite to the opening mechanism 1 is provided with a chamfer 36. This chamfer 36 is a guiding chamfer 36. With the help of the chamfer 36, when the latch lever 32 and the locking hook mechanism 4 are connected, the locking hook mechanism 4 can slide over the latch lever 32 and engage with and lock on the other side of the latch lever 32.

[0023] The locking mechanism 4 includes a latch 41 and a shock absorber 42. The shock absorber 42 is located at the lower end of the latch 41 and is fixedly connected to it. The shock absorber 42 is in contact with the baby carrier. The contact connection can be understood as the shock absorber 42 and the baby carrier having a mutual pressing force when the baby carrier is folded and close to the side wall panel. The shock absorber 42 secures the baby carrier. The setting of the shock absorber 42 can prevent gaps between the baby carrier after it is closed, which will cause noise from collisions. Long-term shaking can easily damage the baby carrier lock. The shock absorber 42 is a shock-absorbing pad, which reduces costs.

[0024] The method of use and principle of this invention, such as Figure 7 As shown, the outer cover plate 5 is installed on the baby carrier, and then the inner cover plate 2 is installed on the outer cover plate 5. The locking hook mechanism 4 is installed on the corresponding aircraft structure. At this time, the latch 41 and the latch bar 32 are connected. When in use, pull the opening handle 11. The rotation of the opening handle 11 causes the latch bar 32 to move downward, and the latch bar 32 and the locking hook mechanism 4 are disengaged, so the baby carrier can be lowered. After use, the baby carrier is lifted up and pressed against the locking hook mechanism 4. With the guidance of the chamfer 36 on the latch bar 32, the locking hook mechanism 4 locks the latch bar 32. At this time, the shock-absorbing pad on the locking hook mechanism 4 also exerts force on the baby carrier to make the baby carrier stable. The present invention can complete the opening and closing operation of the baby carrier with one hand, which is convenient for the user.
