Description

Hinge for glass doors

The present invention relates to a hinge, and more particularly to a hinge suitable for a glass door.

As an example, a conventional hinge 1 disclosed in the Patent Publication No. M412227 of the Republic of China is mainly provided with a first connecting member 11 and a second connection fixed to a door panel (not shown). a shaft 12, a shaft 13 of the first connecting member 11 and the second connecting member 12, a bolt 14 screwed to one end of the rotating shaft 13 and the second connecting member 12, mounted on the rotating shaft 13 and the first A spring unit 16 between the connecting members 11 and driving the rotating shaft 13 to return to the original position through a slider 15 , a slider mounted on the first connecting member 11 and engaged with the sliding rod 15 to define an oil chamber 171 The sleeve 17 and an oil passage 18 for guiding hydraulic oil from the oil chamber 171 in the clockwise direction of the slider 15 and the rotating shaft 13.

Thereby, when an external force pushes the door panel to rotate by an angle, and the rotation of the rotating shaft 13 is driven by the second connecting member 12, the rotating shaft 13 of the deflection angle will press the slider 15 to be displaced downward and compress the spring unit 16, while The hydraulic oil in the oil chamber 171 dampens the displaced slider 15 to slow the rotation speed of the rotating shaft 13 together with the second connecting member 12 and the door panel. When the external force is released, the slider 15 is subjected to The elastic force of the spring unit 16 is upwardly displaced, and the rotating shaft 13 is driven to return to the original position. At the same time, the hydraulic oil between the rotating shaft 13 and the sliding block 15 also forms a damping effect, so that the rotating shaft 13 is returned to the rotating speed. The flow rate of the hydraulic oil from the oil passage 18 to the oil chamber 171 is limited to the purpose of adjusting the return speed of the second connecting member 12 and the door panel.

Due to the limited space of the oil chamber 171, in order to meet the requirement that the door opening angle is large and the large restoring force is required, the two types of elastic elements 161 and 162 are used to enhance the return of the shaft 13 The elastic force at the position. However, although the elastic members 161 and 162 can increase the elastic force at the time of returning, the impedance at the time of opening the door is also increased, so that when the user opens the door, it is necessary to apply a greater force to the door panel to push the door panel open. .

Therefore, the object of the present invention is to provide a hinge suitable for a glass door that is more suitable for use.

Therefore, the present invention is applicable to a hinge of a glass door, and includes a connecting unit, a movable unit, a rotating unit, and a resetting unit.

The rotating unit 4 includes a rotating shaft 41 and a two-axis bolt 42. The shaft 41 is pivoted along the axis X to the shaft hole 221 of the pivot seat 22, and has two end portions 411 that intersect the pair of wall groups 311 and pass through the recesses 312. Each of the axle pins 42 passes through the surrounding wall group 311 along the center line Y direction and is connected to the respective end portions 411 of the rotating shaft 41.

The rotating shaft 41 rotates between a normal position (Fig. 5) and a normal position (Fig. 6, Fig. 7) at an angle θ with the axis X as the center. The angle θ is between 0 and 90. degree.

The reset unit 5 includes a first elastic member 51, a second elastic member 52, and a third elastic member 53 which are disposed along the center line Y in the center hole 222 of the pivot base 22. The first elastic member 51 surrounds the center line Y and has a plurality of coils 511 and has a first height H1 along the center line Y direction. The second elastic member 52 surrounds the first elastic member 51 and has a plurality of coils 521 and has a second height H2 along the center line Y direction. The third elastic member 53 surrounds the second elastic member 52 and has a plurality of coils 531 and has a third height H3 along the center line Y direction. In this embodiment, the second height H2 > the third height H3 > the first height H1, and the difference between the third height H3 and the second height H2 is equivalent to the first segment L1, the first The difference between the height H2 and the first height H1 corresponds to the second segment L2, and the first height H1 corresponds to the third segment L3, whereby the number of the coils 531 in the first segment L1 is < The total number of the coil lines 531, 521 in the second section L2 < the total number of coils 531, 521, 511 in the third section L3.

It should be noted that the third height H3 of the third elastic member 53 is not limited to be smaller than the second height H2, and may be greater than the second height H2 or equal to the second height in other aspects of the embodiment. H2 is lower than the first height H1 or equal to the first height H1.

The damper unit 6 includes a sliding sleeve 61 disposed between the returning unit 5 and the rotating shaft 41 and displaceably disposed along the center line Y in the center hole 222, and a check valve group 62. The sliding sleeve 61 and the rotating shaft 41 and the pivoting seat 22 define an oil chamber 610 into and out of the fluid, and has a through hole 611 communicating with the oil chamber 610 and the central hole 222. The check valve group 62 is disposed between the sliding sleeve 61 and the resetting unit 5, and has a gasket 621 defining a valve hole 620, and a closed position relative to the valve hole 620 (see FIG. 5) and a A valve member 622 that is displaced between the open positions (Fig. 6). When the valve member 622 is in the closed position, the valve member 622 closes the valve bore 620. When the valve member 622 is in the open position, the valve member 622 is away from the valve bore 620.

Referring to FIG. 3, FIG. 4, FIG. 5 and FIG. 6, FIG. 7, when an external force pushes the glass door 7 to rotate the angle θ, the first movable member 31 drives the rotating shaft 41 to rotate from the normal position to the compressed position. At this time, the rotating shaft 41 presses the sliding sleeve 61 downward along the center line Y and compresses the reset unit 5. At the same time, the fluid in the central hole 222 will form a damping pressure on the sliding sleeve 61 due to the smaller volume, and the valve member 622 is pushed up along the center line Y to be disengaged from the spacer 621. The valve bore 620 allows fluid to enter the oil chamber 610 through the central bore 222 through the valve bore 620.

When the sliding sleeve 61 is pressed by the rotating shaft 41 and displaced in the first section L1, only the second elastic member 52 is pressed, so that only the elastic force of the second elastic member 52 is overcome. The glass door 7 can be easily pushed, and as the angle θ becomes larger, when the sliding sleeve 61 is displaced to the second section L2, the third elastic member 53 and the second elastic member 52 are simultaneously pressed. At this time, it is necessary to overcome the elastic force applied by the third elastic member 53 and the second elastic member 52 to push the glass door 7 as the angle θ is closer to 90 degrees, and the sliding sleeve 61 is displaced to the In the third section L3, the third elastic element 53, the second elastic element 52 and the first elastic element 51 are simultaneously pressed. At this time, the third elastic element 53 and the second elastic element 52 need to be overcome. The elastic force applied to the first elastic member 51 can push the glass door 7.

Thereby, the user can push the glass door 7 with a small external force when the glass door 7 is initially opened, and the door opening angle (corresponding to the angle θ of the rotating shaft 41) becomes larger and larger, and is getting more and more. The large resistance prevents the glass door 7 from being too strong or pushing too fast to avoid collision with the door frame.

When the external force is released, the sliding sleeve 61 is displaced upward along the center line Y by the elastic force of the returning unit 5, and drives the rotating shaft 41 to be returned to the normal position from the compressed position, and passes the first The movable member 31 drives the glass door 7 to rotate toward the door frame. At this time, the volume in the center hole 222 is gradually enlarged due to the upward displacement of the sliding sleeve 61, and the volume of the oil chamber 610 is relatively small, so that the valve member is relatively small. The 622 is subjected to the action of the fluid in the oil chamber 610 during the upward displacement of the sliding sleeve 61, and contacts the gasket 621 to close the valve hole 620, so that the fluid is recirculated from the oil chamber 610 through a first-class circuit (not shown). To the central hole 222, thereby generating a damping pressure, delaying the rotational speed of the rotating shaft 41 together with the movable unit 3 and the glass door 7.

When the angle at which the glass door 7 is opened (corresponding to the angle θ of the rotating shaft 41) is small, and the sliding sleeve 61 is only displaced in the first section L1, the rotating shaft 41 is only subjected to the elastic action of the second elastic member 52. The force drives the glass door 7 to be displaced relative to the door frame with a small restoring force. When the glass door 7 is opened, the angle (corresponding to the angle θ of the rotating shaft 41) is large, and the sliding sleeve 61 is displaced by the second section L2. When the rotating shaft 41 is subjected to the elastic force of the third elastic member 53 and the second elastic member 52, the glass door 7 is displaced relative to the door frame with a large restoring force when the glass door 7 is opened. The angle (corresponding to the angle θ of the rotating shaft 41) approaches 90 degrees, and when the sliding sleeve 61 is displaced in the third section L3, the rotating shaft 41 receives the third elastic member 53, the second elastic member 52 and the The first elastic member 51 adds an elastic force to drive the glass door 7 to be displaced relative to the door frame with a maximum restoring force. Thereby, in accordance with the angle at which the glass door 7 is opened, the rotation of the rotating shaft 41 is driven by the partial restoring force, so that when the glass door 7 is closed, it is not affected by the opening angle or the damping effect, and when the door is opened or closed. Smoothness.

Referring to FIG. 8 , FIG. 9 and FIG. 10 , a second embodiment of the present invention is substantially the same as the first embodiment, and includes the connecting unit 2 , the movable unit 3 , the rotating unit 4 , and the returning unit 5 . And the damping unit 6, the difference is:

The center hole 222 is divided along the center line Y direction with a first section L1 adjacent to the shaft hole 221 and a second section L2 away from the shaft hole 221 and connected to the first section L1.

The reset unit 5 includes a resilient member 54 that surrounds the centerline Y. The elastic member 54 has a plurality of coils 541, 542. Each of the two adjacent coils 541 located in the first section L1 is separated by a first gap d1, and each of the two adjacent coils 542 located in the second section L2 is separated by a second gap d2, and the second gap d2 The second gap d2 is smaller than the first gap d1. Thereby, the number of the coils 542 in the second section L2 is made larger than the number of the coils 541 in the first section L1, and the elastic force generated by the coils 542 is greater than the elastic force generated by the coils 541.

When the sliding sleeve 61 is pressed by the rotating shaft 41 to be displaced in the first section L1, the coil 541 of the elastic member 54 is first pressed, whereby the small elastic force can be overcome to open the sliding sleeve 61. Glass door 7 (see Figure 3). When the sliding sleeve 61 is pressed by the rotating shaft 41 and displaced in the second section L2, the coil 541 of the elastic member 54 is pressed to generate a large elastic force with the coil 542, thereby causing the rotating shaft 41 to be subjected to The larger elastic force is restored to the normal position, and the rotation of the rotating shaft 41 can also be driven by the segmental restoring force to further improve the smoothness when opening or closing the door.

Through the above description, the advantages of the foregoing embodiments can be summarized as follows:

The novel can make the rotating shaft 41 receive different elastic forces in a limited space with different numbers of coils, thereby improving the recombination force when the door is closed, and reducing the resistance when the door is opened, so that the opening or closing of the door is more suitable for use.

However, the above is only the embodiment of the present invention.
