The second linkage 120 is composed of two parts 121, 122, and one end of the parts 121, 122 is correspondingly pivoted (or pinned) to the support frames 112, 113, and the other end of the parts 121, 122 is pivoted (or pinned) pinned) on opposite surfaces of the first fin 142 of the first slider 140 . In addition, as mentioned above, the table 111 of this embodiment can also be replaced by a display screen or a seat.

Based on the above-mentioned component relationship, the sliding linkage mechanism as mentioned above is produced, so that when the first sliding member 140 moves closer to or away from the second sliding member 150, the table board 111 is connected to the second sliding member 150 with the supporting frames 112, 113. The pivot joint (corresponding to the pivot joint 153 ) as the center generates rotation relative to the track 130 , which is equivalent to taking the Y axis as the center axis of rotation. Table 111 is rotated relative to track 130 to switch between a folded state (as shown on the left side of Figure 1) and an unfolded state (as shown on the right side of Figure 1, Figure 2A or Figure 2B), and in the folded state, table plate 111 is parallel to track 130 ( or the wall 200), in the unfolded state, the table 111 is perpendicular to the track 130 (or the wall 200).

The latch 160 has a guide surface 161 and a buckle groove 162. When the first slider 140 moves closer to the second slider 150, the holding pin 143 stops at the buckle groove 162 after passing the guide surface 161, as shown in FIG. 2A shown. Furthermore, the guide surface 161 of this embodiment is in the shape of a "ㄑ" and has a first section C1 and a second section C2, and the first section C1 is adjacent to the buckle groove 162 and the second section C2. Here, the extending direction of the locking pin 143 and the pivoting direction of the locking member 160 relative to the second sliding member 150 are parallel to each other (both are parallel to the Y-axis). The locking member 160 also has a stop surface 163 , and the buckle groove 162 adjoins between the stop surface 163 and the guide surface 161 . The unlocking part 170 of the folding device 100 is fixed on the track 130 and adjacent to the slit 131. The latching part 160 is used to bear on the unlocking part 170 to keep a distance from the track 130, and the guiding surface 161 is seated. The moving path of the locking pin 143 will be further described later.

3A to 3E illustrate the state transition process of the foldable device from a side view. Please refer to FIG. 3A to FIG. 3E at the same time. In this embodiment, the track 130 is adapted to be arranged along the direction of gravity G, so that the first sliding member 140 can retract the table 111 through the reciprocating linear lifting action along the direction of gravity G. Fold and unfold actions. Here, the second sliding member 150 is disposed above the first sliding member 140 . Certainly, as mentioned above, the driving method of the first sliding member 140 is not limited, therefore, the user may also drive the table 111 , and the first sliding member 140 is driven to move along the track 130 due to the influence of the aforementioned component relationship.

First, as shown in Fig. 3A to Fig. 3B, since the first sliding member 140 and the second sliding member 150 are combined together by the latching structure, and the latching structure further makes the first linkage 110 maintain the relative track as shown 130 , in this state, the first slider 140 , the second slider 150 , the first linkage 110 and the second linkage 120 are considered as one and move synchronously along the track 130 . The second slider 150 is equivalent to moving from the position Z ₀ to the position Z ₁ .

Next, please refer to FIG. 3B to FIG. 3C , due to the blocking of the unlocking member 170, the second sliding member 150 moves to position _Z2 and then stops, wherein the distance d1 shown in FIG. 3B exists between the unlocking member 170 and the second sliding member 150 Therefore, the relative distance from position _Z1 to position _Z2 shown in FIG. 3C is also shown as distance d1 to represent the moving stroke of the second slider 150 (equivalent to distance d1) during the process from FIG. 3B to FIG. 3C .

It is worth noting that in the process from FIG. 3B to FIG. 3C , the first sliding member 140 has moved from position Z ₃ to position Z ₄ , and its moving distance is significantly greater than the distance d1, because the latching member 160 has moved The surface 171 of the unlocking part 170 is pushed away to release the fastening relationship with the fastening pin 143, so no matter whether the user continues to apply force to the table 111 or the motor drives the first sliding part 140 to move toward the negative Z-axis direction, Both can produce the action course of the table top 111 of the first linkage 110 rotating toward the track 130 and folding, and the folding process from FIG. 3C to the state shown in FIG. 3D and FIG. 3E is sequentially performed.

In other words, the first sliding member 140 and the second sliding member 150 actually move up and down along the direction of gravity G on the track 130 respectively. When the first sliding member 140 and the second sliding member 150 are in a combined state, the first The sliding member 140 and the second sliding member 150 descend synchronously along the gravity direction G for a first stroke and then are unlocked and separated from each other by the unlocking member 170 . The first stroke corresponds to the movement of the second slider 150 from the position Z ₀ to the position Z ₂ . After the separation, the first sliding member 140 continues a second stroke along the direction of gravity G to fold the table 111 , and the second stroke is equivalent to the first sliding member 140 traveling all the way from the position Z ₃ to the position Z ₅ .

In addition, the locking member 160 of this embodiment is freely pivoted to the second fin portion 152 along the Y axis and keeps a distance from the second base portion 151 (or the track 130 ). In order to ensure that when the first sliding member 140 moves, the locking pin 143 on the first fin 142 can smoothly drive the latching member 160, so as to prevent the latching member 160 from deviating from the movement path of the locking pin 143 due to the influence of the center of gravity. Therefore, in this embodiment, the unlocking member 170 is provided on the track 130 so that the latching member 160 can bear against the unlocking member 170 and keep a distance from the track 130 (or the second base 151 ), which is also equivalent to using the unlocking member 170 And the guiding surface 161 of the locking member 160 is maintained on the moving path of the locking pin 143 . In the above supporting situation, the locking member 160 is supported against the unlocking member 170 when the buckling pin 143 is located in the buckling groove 162 or away from the guiding surface 161 . Once the buckling pin 143 is in contact with the guiding surface 161 , the above problem can be ignored, that is, the latching component 160 is driven away from the unlocking component 170 by the buckling pin 143 at this time.

In another not-shown embodiment, a spring may also be connected between the latch 160 and the second sliding member 150 to provide the latch 160 to maintain the aforementioned position (let the latch 160 face the first sliding member 140 movement path) required pre-force.

Because the moving path of the first sliding member 140 (and its locking pin 143 ) is consistent with the direction of gravity G, the guiding surface 161 needs to be as close to the direction of gravity G as possible to perform its guiding function.

Conversely, when the user executes the steps in reverse, that is, from FIG. 3E to FIG. 3A , the foldable device 100 can be unfolded again, and the latch structure combines the first sliding member 140 and the second sliding member 150 together. together, it enables the first slider 140 , the second sliding part 150 , the first linking part 110 and the second linking part 120 are integrated and move along the track 130 synchronously. During the above-mentioned unfolding process, the second sliding member 150 has friction force 1 relative to the track 130, and the first linkage 110 and the second slider 150 have friction force 2 at the pivot joint, and the first linkage 110 and the second linkage There is a friction force three at the pivot joint of the component 120, and a friction force four exists at the pivot joint between the second linkage 120 and the first sliding member 140, wherein the friction force two, friction force three and friction force four are all less than the friction force one, according to The foldable device 100 first unfolds the table 111 as shown in FIG. 3B , and then moves synchronously along the track 130 . In another non-illustrated embodiment, there is a convex structure between the track 130 and the second sliding member 150, which can be arranged on the track 130 or the second sliding member 150, so as to achieve the above-mentioned friction relationship, so as to ensure The second sliding member 150 does not move during the unfolding process of the table board 111 .

Fig. 4 is a schematic diagram of some components of a folding device according to another embodiment of the present invention. Please refer to FIG. 4 . Unlike the previous embodiments, the foldable device of this embodiment includes two rails 130, 230, and the first sliding member 140 is slidably disposed on the rail 130, and the second sliding member 250 is movable. ground on track 230. Here, the rails 130 , 230 are two linear rails parallel to each other, so that the moving paths of the first sliding member 140 and the second sliding member 250 are also linear paths parallel to each other. Moreover, the second slider 250 includes a second base 251, a second fin 152, a pivoting portion 153, an extension 252 and a sleeve 253. Compared with the previous embodiment, the second base 251 is movably worn. Located inside the rail 130, the extension 252 extends from the second fin 152 toward another rail (rail 230), and is sleeved on the rail 230 with a sleeve 253. The other structures are still the same as the previous embodiment, so they are omitted. No longer.

To sum up, in the above-mentioned embodiment of the new creation, the folding device passes through the sliding linkage mechanism composed of the track, the second sliding part, the first sliding part, the first linking part and the second linking part, When the track is erected (consistent with the direction of gravity), the components can be folded and unfolded through the lifting action of the mechanism. In other words, the second sliding member and the first sliding member are slid along paths parallel to each other so as to move closer or farther away from each other, so that the effect of rotating the components to be folded or unfolded can be achieved in this simple motion mode. Furthermore, the track of the folding device is a linear track, so the relative motion between the second sliding member and the first sliding member is a linear motion, and this simple movement mode can smoothly cause other changes to the table of the first linking member. The effect of folding or unfolding helps to simplify the components and their movement patterns, avoiding inconvenience to users due to complicated operations.

Furthermore, the foldable device also includes a latch structure. In one embodiment, it is composed of a latch and a holding pin. successfully maintained in the unfolded state. When the first sliding part and the second sliding part are combined with each other due to the locking structure, the first sliding part, the second sliding part, the first linking part and the second linking part can be regarded as one, and then move along the track synchronously. When the first sliding part and the second sliding part are separated from each other due to the locking structure, the state of folding or unfolding the table board can be achieved by moving the first sliding part and the second sliding part closer or farther away.

In addition, an unlocking piece is provided on the track, so that when the latching piece passes the surface of the unlocking piece, it is pushed away from the buckle pin to complete the unlocking, and at the same time, the unlocking piece can further stop the second sliding piece, so that the first sliding piece Continue and move away from the second slider. Furthermore, tie When the guide surface of the lock piece is not in contact with the buckle pin, the folding device still provides an unlocking piece arranged on the track, so that the latch piece can rest on the unlocking piece so that the guide surface of the latch piece can be maintained at On the moving path of the buckle pin, it is ensured that the locking or unlocking function of the bolt lock can be executed smoothly.
