Detailed Description

As shown in fig. 1 and 2, a hinge 10 according to a first embodiment of the present invention may be applied to a cabinet 12 (e.g., a cabinet of furniture or the like). The cabinet 12 includes a first member 14 and a second member 16, the second member 16 being capable of being opened or closed relative to the first member 14. The hinge 10 comprises a fitting 17, a hinge arm 18, a hinge cup 20, at least one elastic member 22, and a retaining seat 24, wherein the hinge arm 18 is connected between the fitting 17 and the hinge cup 20.

The fitting 17 can be mounted to the first member 14.

The hinge cup 20 can be mounted to the second member 16 with the hinge cup 20 pivotally connected relative to the hinge arm 18. The hinge cup 20 includes a chamber 26. The hinge cup 20 can also be opened (or closed) relative to the hinge arm 18 when the second member 16 is opened (or closed) relative to the first member 14.

The at least one resilient member 22 is mounted within the chamber 26 of the hinge cup 20. Here, two elastic members 22 are taken as an example. Wherein each elastic member 22 is in the form of a torsion spring, and the elastic member 22 can be used to provide a closing elastic force or closing force during the process of pivoting the hinge cup 20 from the open state to the closed state with respect to the hinge arm 18. Specifically, the elastic member 22 includes a first leg 28a, a second leg 28b, and a winding portion 30 connected between the first leg 28a and the second leg 28 b. The first leg 28a abuts against the hinge arm 18, for example, against a cam portion 32 of the hinge arm 18, and preferably, the first leg 28a abuts against the cam portion 32 of the hinge arm 18 through a protective cover 33; the second leg 28b abuts against a wall surface in the chamber 26 of the hinge cup 20. Here, the resilient member 22 is mounted to the hinge cup 20 by a pin 34 passing through the coil 30.

The holder 24 can be mounted to the at least one resilient member 22. Preferably, the retaining base 24 can be engaged against the at least one resilient member 22 by at least one engagement feature 36. Here, two latching features 36 are taken as an example, and each latching feature 36 is used to latch to the winding portion 30 of the elastic member 22. Preferably, the detent features 36 are integrally formed with the holder 24, and the detent features 36 and the holder 24 can be made of plastic or metal material. Here, the detent feature 36 and the holder 24 are made of plastic material, but the implementation is not limited thereto, and the detent feature 36 is a protrusion. Further, the retaining seat 24 may be configured to cover at least a portion of the chamber 26 of the hinge cup 20, such that dust or dirt is prevented from entering the chamber 26 of the hinge cup 20.

As shown in fig. 3, the hinge cup 20 can be in an open position relative to the hinge arm 18. Wherein the at least one elastic member 22 includes a first guiding section 38. Here, the first guiding section 38 is taken as an arc surface. Preferably, the outer contour of the winding portion 30 of the elastic member 22 has the cambered surface. On the other hand, the detent feature 36 of the holder 24 includes a second guide section 40. Here, the second guiding section 40 is taken as one of an arc surface and an inclined surface.

As shown in fig. 4 to 7, when the hinge cup 20 is in the open state relative to the hinge arm 18, a user can displace the retaining base 24 from the outside of the chamber 26 of the hinge cup 20 to a first direction D1 toward the inside of the chamber 26 of the hinge cup 20, so that the retaining base 24 can be clamped to the at least one elastic member 22. Specifically, during the process of the retaining base 24 moving toward the first direction D1, the second guiding section 40 of the latching feature 36 and the first guiding section 38 of the at least one elastic element 22 cooperate with each other to help the retaining base 24 to be latched to the at least one elastic element 22. For example, when the retaining base 24 is displaced in the first direction D1, the second guiding section 40 of the latching feature 36 contacts the first guiding section 38 of the elastic element 22 until the retaining base 24 reaches an installation position M, and the retaining base 24 can be latched to the winding portion 30 of the at least one elastic element 22 through the latching feature 36. In other words, when the holder 24 reaches the mounting position M, the latching feature 36 is forced to be close to the side of the winding portion 30 of the at least one elastic member 22.

As shown in fig. 8, when the hinge cup 20 is in the open position relative to the hinge arm 18, the user can apply a force in a second direction D2 (opposite to the first direction D1) to release the retaining base 24 from the winding portion 30 of the at least one resilient member 22. For example, the user can apply a force in the second direction D2 to pull the holder 24, so that the holder 24 is released from the mounting position M; alternatively, in a preferred embodiment, a bottom wall 48 of the hinge cup 20 has an opening 44, and the opening 44 is communicated with the chamber 26 of the hinge cup 20, according to this configuration, a user can apply a force toward the second direction D2 to the retaining base 24 through the opening 44, so that the latching feature 36 of the retaining base 24 can be unlatched from the winding portion 30 of the at least one resilient member 22, in other words, the retaining base 24 can be moved away from the mounting position M (this part can be sequentially matched with fig. 6, 4 and 3).

As shown in fig. 9, the hinge of the second embodiment of the present invention is substantially different from the first embodiment in that: the holder 24 comprises a passage 200, wherein the hinge further comprises a damper 202 movably mounted in the passage 200 of the holder 24, and the damper 202 is located in correspondence with the hinge arm 18. Further, the damper 202 includes a cylinder 204 and a piston rod 206. The interior of the cylinder 204 includes a buffering medium, which is a technical category that can be understood by a person skilled in the art, and therefore, for the sake of brevity, will not be described herein again. Alternatively, the piston rod 206 can extend relative to the cylinder 204, in this embodiment, the piston rod 206 is directed toward a wall of the hinge cup 20, such as the rear end wall 52.

The damper 202 is used to provide a cushioning effect. For example, when the hinge cup 20 pivots from the open state to the closed state relative to the hinge arm 18, each elastic member 22 can provide a closing elastic force, and the hinge arm 18 pushes against the cylinder 204 of the damper 202, so that the piston rod 206 of the damper 202 can push against the rear end wall 52 of the hinge cup 20, and the piston rod 206 and the cylinder 204 can contract relatively to generate a damping effect. In other words, when the hinge is applied to the cabinet 12, the second member 16 has a damping effect with respect to a stroke (e.g., a final stroke) of the first member 14 from the opening to the closing.

As shown in fig. 10, a hinge according to a third embodiment of the present invention. The third embodiment differs from the second embodiment described above substantially in that: the hinge further includes an adjustment member 300 movably mounted to the holder 24.

Further, the holder 24 can be engaged to the winding portion 30 of the at least one elastic member 22 via the engaging feature 36, and the damper 202 can be movably mounted in the channel 200 of the holder 24.

The hinge cup 20, on the other hand, includes a pair of side walls 46, a bottom wall 48, a front end wall 50 and a rear end wall 52. Preferably, the pair of sidewalls 46 has a pair of first connection holes 54 corresponding to each other and a pair of second connection holes 56 corresponding to each other (fig. 10 shows only one first connection hole 54 and one second connection hole 56 due to the view angle). The bottom wall 48 is extended between the pair of sidewalls 46. The front end wall 50 is extendedly connected to the front ends of the pair of side walls 46. The rear end wall 52 is extendedly connected to the rear ends of the pair of side walls 46. The pair of sidewalls 46, the bottom wall 48, the front end wall 50, and the rear end wall 52 collectively define the chamber 26. The bottom wall 48 in the compartment 26 includes a pair of ears 58 (only one ear 58 is shown in fig. 10 due to the perspective), and each ear 58 corresponds to the second connecting hole 56 of each side wall 46. Further, the hinge cup 20 is pivotally connected to the hinge arm 18. For example, a shaft 62 is passed through the first coupling hole 54 to pivotally couple the hinge cup 20 to the hinge arm 18.

Each elastic member 22 is installed between the sidewall 46 of the hinge cup 20 and the ear 58, and each elastic member 22 is correspondingly inserted through the second connecting hole 56 of the sidewall 46, the winding portion 30 of the elastic member 22, and the ear 58 by the pin 34, so that each elastic member 22 can be positioned in the chamber 26.

As best seen in fig. 10 and 11, the holder 24 preferably includes an upper portion 66, a lower portion 68 positioned opposite the upper portion 66, and a body portion 70 connected between the upper portion 66 and the lower portion 68. The upper portion 66 has a first mark 72a, a second mark 72b, and a third mark 72c (as shown in fig. 10) on its surface, and the upper portion 66 has a first abutting portion 74a, a second abutting portion 74b, and a third abutting portion 74c (as shown in fig. 11) on its periphery facing the rear end wall 52 of the hinge cup 20. Preferably, the first mark 72a, the second mark 72b, and the third mark 72c are feature marks of a character, a number, or a figure. Based on these signatures, the operator can recognize and learn the stroke of the cushioning effect provided by the damper 202. The periphery of the lower portion 68 has a lip section 76; the body portion 70 has the passage 200.

The damper 202 is movably mounted in the channel 200 of the holder 24, and when the damper 202 is mounted in the channel 200 of the holder 24 and the hinge cup 20 is closed relative to the hinge arm 18, the damper 202 is pushed and displaced by the hinge arm 18.

As best seen in fig. 10, 11 and 12, the adjustment member 300 is positioned between the upper portion 66 and the lower portion 68 (lip 76) of the holder 24. The adjustment assembly 300 includes an upper bracket 302, a lower bracket 304, and a side plate 306. The lower rack 304 is positioned relative to the upper rack 302; the side plate 306 is coupled between the upper bracket 302 and the lower bracket 304, and the side plate 306 has a surface 308. The adjusting member 300 can be movably supported against the holder 24 by one of the upper bracket 302 and the lower bracket 304.

Furthermore, the upper bracket 302 of the adjusting member 300 has a tip portion 310, an operation portion 312 and a locking portion 314. When the adjusting element 300 is adjusted to move relative to the holder 24, the engaging portion 314 can be selectively located at the first engaging portion 74a, the second engaging portion 74b, or the third engaging portion 74c of the holder 24, so that the engaging portion 314 can be slightly engaged with the first engaging portion 74a, the second engaging portion 74b, or the third engaging portion 74 c; and the tip portion 310 is selectively directed to the first mark 72a, the second mark 72b, or the third mark 72c of the holder 24 for the operator to recognize the adjusted position of the adjuster 300; in addition, the operation portion 312 facilitates the operator to pull the adjusting member 300, so that the adjusting member 300 can move and displace relative to the holder 24.

As shown in fig. 12 and 13, the side plate 306 of the adjusting member 300 has a first contact portion 316, a second contact portion 318, and a third contact portion 320, and the first, second, and

third contact portions

316, 318, and 320 have a first distance X1, a second distance X2, and a third distance X3 respectively corresponding to the surface 308 of the side plate 306. Wherein the first distance X1 is greater than the second distance X2; the second distance X2 is greater than the third distance X3.

As shown in fig. 11 and 14, when the operator operates the adjusting member 300 via the operating portion 312 to movably displace the adjusting member 300 to a first position relative to the retaining base 24, the latching portion 314 is able to be correspondingly latched to the first abutting portion 74a (as shown in fig. 12), the tip portion 310 of the adjusting member 300 is correspondingly indicated by the first indication 72a, and the piston rod 206 of the damper 202 is correspondingly indicated by the first contact portion 316. In this state, a first empty section S1 is formed between the damper 202 and the hinge arm 18.

As shown in fig. 11 and 15, when the operator operates the adjusting element 300 via the operating portion 312 to movably displace the adjusting element 300 to a second position relative to the retaining base 24, the latching portion 314 is able to correspondingly latch against the second abutting portion 74b, the tip portion 310 of the adjusting element 300 is correspondingly indicated by the second indication 72b, and the piston rod 206 of the damper 202 is correspondingly indicated by the second contact portion 318. In this state, a second empty section S2 is formed between the damper 202 and the hinge arm 18.

As shown in fig. 11 and 16, when the operator operates the adjusting element 300 via the operating portion 312 to movably displace the adjusting element 300 to a third position relative to the holder 24, the latching portion 314 is able to correspondingly latch against the third abutting portion 74c, the tip portion 310 of the adjusting element 300 is correspondingly indicated by the third indication 72c, and the piston rod 206 of the damper 202 is correspondingly indicated by the third contact portion 320. In this state, a third empty section S3 is formed between the damper 202 and the hinge arm 18.

Fig. 17, 18 and 19 show the operation of the damper 202 according to the third embodiment of the present invention to provide the first damping action to the hinge.

When the operator adjusts the adjusting member 300 to the first position and the hinge cup 20 is in an open state (as shown in fig. 17) relative to the hinge arm 18, since the hinge arm 18 is pivoted to the hinge cup 20 via the shaft member 62, the hinge cup 20 can be operated from the open state to pivot relative to the hinge arm 18 to a closed state, and during the closing process, the elastic member 22 can provide a closing elastic force during the closing end stroke, and the first leg 28a of the elastic member 22 abuts against the cam portion 32 of the hinge arm 18 via the protective sleeve 33, so that the first leg 28a of the elastic member 22 or the cam portion 32 of the hinge arm 18 can be protected.

During the process of closing the hinge cup 20 to the adjacent end stroke relative to the hinge arm 18 (as shown in fig. 18), the hinge arm 18 pushes the damper 202 according to the first empty segment S1, so that the piston rod 206 is pressed against the first contact portion 316 of the adjustment member 300. In detail, when the hinge cup 20 is closed to a first predetermined angle θ 1 with respect to the hinge arm 18, the hinge arm 18 will push against the cylinder 204 of the damper 202, so that the cylinder 204 of the damper 202 can displace in the channel 200 of the retaining seat 24, so that the piston rod 206 contracts with respect to the cylinder 204 and generates a first damping action F1 through a damping medium 207 inside the cylinder 204 of the damper 202 until the hinge cup 20 is in a closed state with respect to the hinge arm 18 (as in the state of fig. 19). The buffering medium 207 may include a piston 210 and an auxiliary elastic member 212, and preferably, the buffering medium 207 further includes a buffering medium fluid. In practice, the damping medium of the damper 202 can be designed according to the requirement, but is not limited thereto.

Fig. 20 shows the action of the damper 202 of the third embodiment of the present invention to provide the second damping action to the hinge.

Similarly, when the operator adjusts the adjustment member 300 to the second position, during the closing of the hinge cup 20 to the hinge arm 18 to the near end stroke, the hinge arm 18 pushes the damper 202 according to the second empty segment S2, so that the piston rod 206 bears against the second contact portion 318 of the adjustment member 300. In detail, when the hinge cup 20 is closed to a second predetermined angle θ 2 relative to the hinge arm 18, the hinge arm 18 will push against the cylinder 204 of the damper 202, so that the cylinder 204 of the damper 202 can be displaced in the channel 200 of the retaining seat, so that the piston rod 206 contracts relative to the cylinder 204 to generate a second damping action F2 until the hinge cup 20 is in a closed state relative to the hinge arm 18.

Fig. 21 is a schematic diagram showing the action of the damper 202 according to the third embodiment of the present invention, which can provide the third damping effect to the hinge.

Similarly, when the operator adjusts the adjustment member 300 to the third position, during the closing of the hinge cup 20 to the hinge arm 18 to the near end stroke, the hinge arm 18 pushes the damper 202 according to the third empty segment S3, so that the piston rod 206 bears against the third contact portion 320 of the adjustment member 300. In detail, when the hinge cup 20 is closed to a third predetermined angle θ 3 with respect to the hinge arm 18, the hinge arm 18 will push against the cylinder 204 of the damper 202, so that the cylinder 204 of the damper 202 can be displaced in the channel 200 of the retaining seat 24, so that the piston rod 206 contracts with respect to the cylinder 204 to generate a third damping action F3 until the hinge cup 20 is in a closed state with respect to the hinge arm 18.

Therefore, according to the position of the adjusting member 300 relative to the retaining seat 24 being adjusted, during the process of closing the hinge cup 20 to the adjacent end stroke relative to the hinge arm 18, the hinge arm 18 pushes against the damper 202 according to the adjustment, so that the damper 202 can generate the required predetermined damping effect, thereby satisfying the damping requirement when the second member 16 of the cabinet 12 is closed relative to the first member 14, and accordingly achieving the protection and silencing effects.

From the above description, it can be seen that the enhanced efficacy and advantages of the present invention are:

a. the retaining seat 24 is engaged with at least one elastic member 22 to prevent dust or dirt from entering into the chamber 26 of the hinge cup 20.

b. A damper 202 may be movably mounted in the passage 200 of the holder 24 to provide a cushioning function to the hinge for cushioning the second member 16 (or hinge cup 20) from opening to closing relative to the first member 14 (or hinge arm 18).

c. The damping stroke of the damper 202 can be adjusted by the adjuster 300.

Although the present invention has been described with reference to the present specific embodiments, it will be recognized by those skilled in the art that the above embodiments are illustrative only, and various equivalent changes and modifications may be made without departing from the spirit of the present invention, and therefore, it is intended to cover in the appended claims all such changes and modifications as fall within the true spirit of the invention.
