Description

[Technical Field]

[0001] The present invention relates to a hinge. [Background technology]

[0002] The hinge has a first blade and a second blade, and connects the first blade and the second blade while restricting the second blade from moving horizontally and vertically relative to the first blade and allowing the second blade to rotate relative to the first blade.

[0003] Such hinges are used, for example, with doors and door frames. In one example of use, the first blade is attached to the door, and the second blade is attached to the door frame. Some conventional hinges press the second blade against the first blade. With such hinges, when the door is open relative to the door frame, the second blade is pressed against the first blade, so the door can be maintained in an open position relative to the door frame. Summary of the Invention [Problem to be solved by the invention]

[0004] However, conventional hinges have a problem in that the mechanism for pressing the second blade against the first blade is complicated. In other words, conventional hinges have room for improvement in simplifying the configuration while still having a mechanism for pressing the second blade against the first blade.

[0005] Therefore, the present invention has been made in view of the above circumstances, and has an object to provide a hinge that is capable of pressing the second blade against the first blade and has a simple structure. [Means for solving the problem]

[0006] In order to solve the above problems, the hinge of the present invention comprises a first blade having a first sleeve and a first body, a second blade having a second sleeve and a second body, and a fastening mechanism having a first fastening member inserted into the first sleeve and the second sleeve, respectively, and a second fastening member that can be fastened to the first fastening member, and by changing the fastening force between the first fastening member and the second fastening member in the fastening mechanism, the pressing force of the second blade against the first blade can be changed.

[0007] Furthermore, the hinge of the present invention comprises a first intervening member attached to the first blade and a second intervening member attached to the second blade, wherein the second blade rotates relative to the first blade while the first intervening member and the second intervening member are in contact with each other, and the first intervening member and the second intervening member are formed of different materials.

[0008] In addition, the hinge of the present invention has a through hole into which the first fastening member can be inserted and is provided with an elastic member that can be elastically deformed, and when the first fastening member is inserted into the through hole and the second fastening member is fastened to the first fastening member, the elastic member elastically deforms, thereby increasing the pressing force of the second blade against the first blade. [Effects of the Invention]

[0009] According to the hinge of the present invention, since it has the above-mentioned configuration, it is possible to provide a hinge that is capable of pressing the second blade against the first blade and has a simple configuration. [Brief explanation of the drawings]

The present invention is not limited to the contents described in the following embodiments. Furthermore, the components described below include those that can be easily conceived by a person skilled in the art and those that are substantially the same. Furthermore, the configurations described below can be combined as appropriate. Furthermore, various omissions, substitutions, or modifications of the configuration can be made within the scope of the gist of the present invention.

[0012] [First embodiment] First, the configuration of the hinge 1 according to the first embodiment will be described with reference to FIGS. 1 to 7. FIG. 1 is a perspective view showing the hinge 1 according to the first embodiment in use. FIG. 2 is a plan view of the hinge 1 shown in FIG. 1. FIG. 3 is a bottom view of the hinge 1 shown in FIG. 1. FIG. 4 is a cross-sectional view taken along the arrow AA in FIG. 2. FIG. 5 is a cross-sectional view showing the first internal space 2s and the second internal space 3s of the hinge 1 shown in FIG. 1. FIG. 6 is an exploded perspective view of the hinge 1 shown in FIG. 1 as seen from the other side in the vertical direction Y. FIG. 7 is an exploded perspective view of the hinge 1 shown in FIG. 1 as seen from one side in the vertical direction Y.

[0013] 1 to 7, the hinge 1 according to the first embodiment has a lateral direction X, a vertical direction Y, and a thickness direction Z. The lateral direction X, the vertical direction Y, and the thickness direction Z are perpendicular to one another. In the hinge 1 according to this embodiment, the vertical direction Y is, for example, the direction in which an axis 4y of the shaft portion 411 of the first fastening member 41 extends.

[0014] 6 and 7, the hinge 1 according to this embodiment includes a first blade 2, a first intervening member 23, a second blade 3, a second intervening member 33, a fastening mechanism 4, an elastic member 6, and a washer 7. The hinge 1 according to this embodiment includes at least the first blade 2, the second blade 3, a first fastening member 41, and a second fastening member 42 as essential components. The hinge 1 according to this embodiment also includes the first intervening member 23, the second intervening member 33, the elastic member 6, and the washer 7 to perform additional functions.

[0015] The first blade 2 has, for example, one first sleeve 21 and one first body 22. The first blade 2 is formed, for example, by painting (for example, nickel plating) a metal material (for example, a zinc alloy). In the first blade 2 according to this embodiment, the first sleeve 21 and the first body 22 are integrally formed.

[0016] Each of the first sleeves 21 is disposed, for example, at one end of the first body 22 in the lateral direction X. As shown in FIG. 5, each of the first sleeves 21 is formed to have, for example, a first internal space 2s.

[0017] The first internal space 2s has, for example, a cylindrical first portion 2s1 in which a shaft portion 411 of a first fastening member 41 (described later) is disposed, and two second portions 2s2 that are disposed radially outside the first portion 2s1 and into which first engaging protrusions 232 of a first intervening member 23 (described later) are inserted. The two second portions 2s2 are disposed, for example, at both ends of the first sleeve 21 in the longitudinal direction Y.

[0018] 6 and 7 is formed in, for example, a plate shape. The first body 22 has a first through hole 2H penetrating the first body 22 in the thickness direction Z. For example, the shank of a first bolt Bo1 is inserted into the first through hole 2H, and the first body 22 is attached to the door D1 by the first bolt Bo1 (see FIG. 1). The first body 22 according to this embodiment has, for example, a plurality of (for example, two) first through holes 2H.

[0019] The second blade 3 has, for example, a pair of second sleeves 31 and one second body 32. The second blade 3 is formed, for example, by painting (for example, nickel plating) a metal material (for example, a zinc alloy). In the second blade 3 according to this embodiment, the second sleeve 31 and the second body 32 are integrally formed.

[0020] The pair of second sleeves 31 are arranged at a predetermined distance in the longitudinal direction Y. More specifically, the pair of second sleeves 31 are arranged at a predetermined distance so that the first sleeve 21, the first intervening member 23, and the second intervening member 33 can be disposed between the pair of second sleeves 31. Each of the pair of second sleeves 31 is arranged, for example, at the other end of the second main body 32 in the lateral direction X. Each of the second sleeves 31 is formed to have, for example, a second internal space 3s, as shown in FIG. 5 .

[0021] The pair of second sleeves 31 includes a second sleeve 31α disposed on one side in the longitudinal direction Y and a second sleeve 31β disposed on the other side in the longitudinal direction Y.

[0022] Of the pair of second sleeves 31, the second internal space 3s of the second sleeve 31α arranged on one side in the vertical direction Y has, for example, as shown in Figures 4 and 5, a third portion 3s11 in which the shaft portion 411 of the first fastening member 41 described later is arranged, and a fourth portion 3s12 in which the head portion 412 of the first fastening member 41, the elastic member 6, and the washer 7 are arranged.

[0023] Of the pair of second sleeves 31, the second internal space 3s of the second sleeve 31β that is positioned on the other side in the vertical direction Y has, for example, a fifth portion 3s13 in which the shaft portion 411 of the first fastening member 41 described later is positioned, and a sixth portion 3s14 in which the second fastening member 42 is positioned.

[0024] Further, an engaging recess 311 recessed from the outside to the inside in the radial direction of the second sleeve 31 is formed on the outer circumferential surface of each second sleeve 31. In the second sleeve 31 according to this embodiment, a pair of engaging recesses 311 is arranged so as to face each other in the radial direction.

[0025] Of the pair of second sleeves 31, the second sleeve 31α disposed on one side in the longitudinal direction Y has an engagement recess 311 disposed at the other end of the second sleeve 31.

[0026] Of the pair of second sleeves 31, the second sleeve 31β disposed on the other side in the longitudinal direction Y has an engagement recess 311 disposed at one end of the second sleeve 31.

[0027] The second body 32 shown in Fig. 1 is formed, for example, in a plate shape. The second body 32 has a second through hole 3H penetrating the second body 32 in the thickness direction Z (see Figs. 6 and 7). For example, the shank of a second bolt Bo2 is inserted into the second through hole 3H, and the second body 32 is attached to the door frame D2 by the second bolt Bo2 (see Fig. 1). The second body 32 according to this embodiment has, for example, a plurality of second through holes 3H (for example, two).

[0028] The first intervening member 23 shown in Figures 6 and 7 is formed separately from the first blade 2. The first intervening member 23 is formed, for example, by a flat first intervening member body 231 and a first engaging protrusion 232 protruding from the first intervening member body 231 in the vertical direction Y. The first intervening member body 231 has a through hole 23H in the center. The shaft 411 of the first fastening member 41 is inserted into the through hole 23H of the first intervening member 23 (see Figure 4).

[0029] The first intervening member 23 is made of, for example, a synthetic resin (for example, polyacetal resin). The first intervening member 23 is attached to the first blade 2 by inserting the first engaging protrusion 232 into the second portion 2s2 of the first sleeve 21.

[0030] The hinge 1 according to this embodiment includes a plurality of (for example, two) first intervening members 23. More specifically, of the plurality of first intervening members 23, first intervening member 23α arranged on one side in the longitudinal direction Y is arranged between first sleeve 21 of first blade 2 and second sleeve 31α arranged on one side in the longitudinal direction Y of second blade 3, and prevents contact between first sleeve 21 and second sleeve 31α.

[0031] Of the multiple first intervening members 23, the first intervening member 23β arranged on the other side of the vertical direction Y is arranged between the first sleeve 21 of the first blade 2 and the second sleeve 31β arranged on the other side of the vertical direction Y of the second blade 3, and prevents contact between the first sleeve 21 and the second sleeve 31β.

[0032] The first intervening member 23α arranged on one side in the longitudinal direction Y is attached to one end of the first sleeve 21 in the longitudinal direction Y and is in contact with the second intervening member 33α attached to the second sleeve 31α.

[0033] The first intervening member 23β arranged on the other side in the longitudinal direction Y is attached to the other end of the first sleeve 21 in the longitudinal direction Y and is in contact with the second intervening member 33β attached to the second sleeve 31β.

[0034] First intervening member 23 is made of synthetic resin, while second intervening member 33 is made of a metal material. In other words, first intervening member 23 is made of a material different from that of second intervening member 33. First intervening member 23 having this configuration has the function of suppressing noise generated when second blade 3 rotates relative to first blade 2 about axis 4y.

[0035] The second intervening member 33 is formed separately from the second blade 3. The second intervening member 33 is formed, for example, by a flat second intervening member body 331 and a second engaging protrusion 332 protruding from the second intervening member body 331 in the vertical direction Y. The second intervening member body 331 has a through hole 33H in the center. The shaft 411 of the first fastening member 41 is inserted into the through hole 33H of the second intervening member 33 (see FIG. 4).

[0036] The second intervening member 33 is formed of, for example, a metal material (stainless steel, for example). The second intervening member 33 is attached to the second blade 3 by inserting the second engaging protrusion 332 into the engaging recess 311 of the second sleeve 31.

[0037] The hinge 1 according to this embodiment includes a plurality of (for example, two) second intervening members 33. More specifically, of the plurality of second intervening members 33, second intervening member 33α arranged on one side in the longitudinal direction Y is arranged between first sleeve 21 of first blade 2 and second sleeve 31α arranged on one side in the longitudinal direction Y of second blade 3, and prevents contact between first sleeve 21 and second sleeve 31α.

[0038] Of the multiple second intervening members 33, the second intervening member 33β arranged on the other side of the vertical direction Y is arranged between the first sleeve 21 of the first blade 2 and the second sleeve 31β arranged on the other side of the vertical direction Y of the second blade 3, and prevents contact between the first sleeve 21 and the second sleeve 31β.

[0039] The second intervening member 33α disposed on one side in the longitudinal direction Y comes into contact with the first intervening member 23α attached to the second sleeve 31α disposed on one side in the longitudinal direction Y.

[0040] The second intervening member 33β disposed on the other side in the longitudinal direction Y comes into contact with the first intervening member 23β attached to the second sleeve 31β disposed on the other side in the longitudinal direction Y.

[0041] The first intervening member 23 is made of a synthetic resin, while the second intervening member 33 is made of a metal material. In other words, the second intervening member 33 is made of a material different from that of the first intervening member 23. The second intervening member 33 having this configuration has the function of suppressing noise generated when the second blade 3 rotates relative to the first blade 2 about the axis 4y.

[0042] The fastening mechanism 4 shown in FIG. 4 includes a first fastening member 41 and a second fastening member 42. The first fastening member 41 is, for example, a bolt. The first fastening member 41 includes, for example, a cylindrical shank 411 extending in the vertical direction Y, and a head 412 disposed at one end of the shank 411. A first screw 41N is formed on the outer peripheral surface of the other end of the shank 411 in the vertical direction Y according to this embodiment. Furthermore, a recess (hexagonal hole) 412H into which the tip of a tool (hexagonal wrench) can be inserted is formed at the end of the head 412 of the first fastening member 41 in the vertical direction Y.

[0043] The second fastening member 42 is, for example, a nut. The second fastening member 42 is, for example, formed in a cylindrical shape. The second fastening member 42 has an inner circumferential surface formed with a second screw 42N that screws into the first screw 41N.

[0044] The elastic member 6 is, for example, a disc spring. The elastic member 6 has a through-hole 6H in the center and is formed like a conical plate with an open bottom. The shaft 411 of the first fastening member 41 is inserted into the through-hole 6H of the elastic member 6. When an external force is applied in the vertical direction Y and the elastic member 6 is compressed and elastically deformed in the vertical direction Y, an elastic restoring force is generated in directions in which the elastic members 6 move away from each other in the vertical direction Y. The hinge 1 according to this embodiment includes a pair (i.e., two) of elastic members 6. The elastic members 6 are formed, for example, by providing a surface coating of iron oxide on a metal material (carbon steel, for example). When the first fastening member 41 and the second fastening member 42 are fastened together, the elastic member 6 elastically deforms, thereby increasing the pressing force of the second blade 3 against the first blade 2.

[0045] The washer 7 has a through hole 7H in the center and is formed in a cylindrical shape. The hinge 1 according to this embodiment includes a pair (i.e., two) of washers 7, which are arranged to sandwich the pair of elastic members 6. The shaft 411 of the first fastening member 41 is inserted into the through hole 7H of the washer 7 (see FIG. 4). The washer 7 according to this embodiment functions to reliably sandwich the pair of elastic members 6.

[0046] Next, the assembly of the hinge 1 according to this embodiment will be described with reference to Figures 6 and 7. First, the worker attaches the first intervening member 23α to one side of the first sleeve 21 in the longitudinal direction Y by engaging the first engaging protrusion 232 of one of the first intervening members 23 with the second portion 2s2 of the first sleeve 21 on one side in the longitudinal direction Y.

[0047] Next, the worker attaches the first intervening member 23β to the other side of the first sleeve 21 in the longitudinal direction Y by engaging the first engaging protrusion 232 of the other first intervening member 23 with the second part 2s2 of the first sleeve 21 on the other side of the longitudinal direction Y.

[0048] Next, the worker attaches the second intervening member 33α to the second sleeve 31α by engaging the second engaging protrusion 332 of the second intervening member 33α with the engaging recess 311 of the second sleeve 31α on one side in the vertical direction Y.

[0049] Next, the worker attaches the second intervening member 33β to the second sleeve 31β by engaging the second engaging protrusion 332 of the second intervening member 33β with the engaging recess 311 of the second sleeve 31β on the other side in the vertical direction Y.

[0050] Next, the worker places the elastic member 6 and the washer 7 in the fourth portion 3s12 of the second internal space 3s of the second sleeve 31α arranged on one side of the vertical direction Y, and places the second fastening member 42 in the sixth portion 3s14 of the second internal space 3s of the second sleeve 31 arranged on the other side of the vertical direction Y.

[0051] Next, the worker inserts the shaft portion 411 of the first fastening member 41 through the through hole 7H of the washer 7, the through hole 6H of the elastic member 6, the third portion 3s11 of the second sleeve 31, the through hole 33H of the second intervening member 33, the through hole 23H of the first intervening member 23, and the fifth portion 3s13 of the second sleeve 31.

[0052] Finally, the worker inserts a tool into the recess 412H in the head 412 of the first fastening member 41 and rotates the tool to screw together the first screw 41N of the first fastening member 41 and the second screw 42N of the second fastening member 42, thereby assembling the hinge 1. Then, in the assembled hinge 1, each of the pair of second sleeves 31 presses against the first sleeve 21.

[0053] The hinge 1 assembled in this manner comprises at least a first blade 2 and a second blade 3, and connects the first blade 2 and the second blade 3 while restricting the second blade 3 from moving relative to the first blade 2 in the horizontal direction X and the vertical direction Y, and allowing the second blade 3 to rotate relative to the first blade 2 about the axis 4y.

[0054] As described above, the hinge 1 according to this embodiment includes the first blade 2 having the first sleeve 21 and the first body 22, the second blade 3 having the second sleeve 31 and the second body 32, the first fastening member 41 inserted into the first sleeve 21 and the second sleeve 31, respectively, and the second fastening member 42 fastenable to the first fastening member 41. The fastening mechanism 4 changes the fastening force between the first fastening member 41 and the second fastening member 42, thereby changing the pressing force of the second blade 3 against the first blade 2. In other words, the hinge 1 according to this embodiment can press the pair of second sleeves 31 against the first sleeve 21 by the fastening mechanism 4. Therefore, the hinge 1 according to this embodiment restricts the door D1 from rotating even when an external force on the door D1 is removed, and can maintain the door D1 in an open state, for example. As a result, the hinge 1 according to this embodiment is capable of pressing the pair of second sleeves 31 of the second blade 3 against the first sleeve 21 of the first blade 2, and can have a simple configuration.

[0055] In the hinge 1 according to this embodiment, a recess (hexagonal hole) 412H into which the tip of a tool (hexagonal wrench) can be inserted is formed in the first fastening member 41. Therefore, the pressing force of the second blade 3 against the first blade 2 can be appropriately changed using a tool both at the manufacturing factory for the hinge 1 and at the installation site where the hinge 1 is attached to the door D1 and the door frame D2.

[0056] In the hinge 1 according to this embodiment, the first fastening member 41, the second fastening member 42, the elastic member 6, and the washer 7 are commercially available, which makes it easy to manufacture the hinge 1.

[0057] Furthermore, the hinge 1 according to this embodiment includes a first intervening member 23 attached to the first blade 2 and a second intervening member 33 attached to the second blade 3. The second blade 3 rotates relative to the first blade 2 while the first intervening member 23 and the second intervening member 33 are in contact with each other, and the first intervening member 23 and the second intervening member 33 are formed of different materials. Therefore, the hinge 1 according to this embodiment can suppress the noise generated when the second blade 3 rotates relative to the first blade 2 about the axis 4y by means of the first intervening member 23 and the second intervening member 33. On the other hand, in a hinge in which the first intervening member 23 and the second intervening member 33 are not present between the first blade 2 and the second blade 3, the noise generated when the second blade rotates relative to the first blade about the axis is louder than the noise generated by the hinge 1 according to this embodiment. Furthermore, in a hinge having a first intervening member and a second intervening member formed of the same material between the first blade 2 and the second blade 3, the sound generated when the second blade is rotated relative to the first blade around the axis is louder than the sound of the hinge 1 of this embodiment.

[0058] Furthermore, the hinge 1 according to this embodiment has a through hole 6H into which the first fastening member 41 (more specifically, the shaft 411) can be inserted, and is equipped with an elastically deformable elastic member 6. When the first fastening member 41 (more specifically, the shaft 411) is inserted into the through hole 6H and the first fastening member 41 and the second fastening member 42 are fastened together, the elastic member 6 elastically deforms, thereby increasing the pressing force of the second blade 3 against the first blade 2. Therefore, the hinge 1 according to this embodiment can reliably maintain the door D1 in an open state relative to the door frame D2 even when the force on the door D1 is removed.

[0059] [Second embodiment] Next, the configuration of the hinge 1A according to the first embodiment will be described with reference to FIGS. 8 to 11. FIG. 8 is a cross-sectional view of the hinge 1A according to the second embodiment, and is a cross-sectional view similar to FIG. 4. FIG. 9 is a cross-sectional view similar to FIG. 5, showing the first internal space 2sA and the second internal space 3s of the hinge 1A shown in FIG. 8. FIG. 10 is an exploded perspective view of the hinge 1A shown in FIG. 8, viewed from the other side in the vertical direction Y. FIG. 11 is an exploded perspective view of the hinge 1A shown in FIG. 8, viewed from one side in the vertical direction Y. Note that in the configuration of the hinge 1A according to the second embodiment, components similar to those of the hinge 1 according to the first embodiment are designated by the same reference numerals, and description thereof will be omitted.

[0060] As shown in FIG. 8, the hinge 1A of this embodiment includes a first blade 2A, a second blade 3, a fastening mechanism 4, a first intervening member 23A, an elastic member 6, a washer 7, and a second intervening member 33.

[0061] The first blade 2A and the first intervening member 23A according to this embodiment are integrally formed from, for example, a synthetic resin (for example, polyacetal resin).

[0062] The first blade 2A has, for example, one first sleeve 21A and one first body 22.

[0063] As shown in FIG. 9, the first sleeve 21A according to this embodiment is formed to have, for example, a cylindrical first internal space 2sA.

[0064] As shown in FIGS. 8 and 9, the first internal space 2sA according to this embodiment is formed, for example, only by the first portion 2s1 in which the shank 411 of the first fastening member 41 is disposed.

[0065] The first intervening member 23A according to this embodiment is formed only by a first intervening member main body 231 in the shape of a flat plate.

[0066] According to hinge 1A of this embodiment, first blade 2A and first intervening member 23A are integrally formed, eliminating the need to attach first intervening member 23A to first blade 2A. Therefore, hinge 1A of this embodiment can be easily manufactured by reducing the number of manufacturing steps.

[0067] In the hinge 1A according to this embodiment, the first fastening member 41, the second fastening member 42, the elastic member 6, and the washer 7 are commercially available, which makes it easy to manufacture the hinge 1A.

[0068] In the above-described embodiment, the hinges 1 and 1A are used on the door D1 and the door frame D2. However, the use of the hinges 1 and 1A according to the present embodiment is not limited thereto. For example, the hinges 1 and 1A according to the present embodiment can be used in a notebook PC including a personal computer main body with a keyboard and a display device. When used in a notebook PC, the first blades 2 and 2A are attached to the personal computer main body, and the second blade 3 is attached to the display device. In such a notebook PC, the fastening mechanism 4 can press the pair of second sleeves 31 against the first sleeves 21 and 21A. Therefore, even if the user manually changes the angle of the display device relative to the personal computer main body and then releases the display device, gravity prevents the display device from rotating, allowing the display device to remain open relative to the personal computer main body. As a result, the hinges 1 and 1A according to the present embodiment can press the second sleeve 31 of the second blade 3 against the first sleeves 21 and 21A of the first blades 2 and 2A, while maintaining a simple configuration. The hinges 1 and 1A according to this embodiment can also be used in other devices, for example.

[0069] The hinges 1 and 1A according to the above-described embodiments have been described as including the first blades 2 and 2A, the second blades 3, the fastening mechanism 4, the first intervening member 23, the elastic member 6, the washer 7, and the second intervening member 33. However, the hinges 1 and 1A according to the present embodiment are not limited to this. For example, the hinges 1 and 1A according to the above-described embodiments may not include the first intervening member 23, the second intervening member 33, the elastic member 6, and the washer 7 if there is no need to perform additional functions.

[0070] Although the present invention has been described above with reference to specific embodiments, the present invention is not limited to the above embodiments.
