Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gate adjustment hinge which can be moved forward, backward, leftward and rightward.

[0002]

2. Description of the Related Art As an adjustment hinge for a gate, a lower hinge having a movement adjusting function is arranged on a pillar side, and an upper hinge which is usually fixed only is arranged on a door, and a lower hinge is arranged. It is common to fit the pipe part of the upper hinge into the shaft center provided and hang the door on the pillar. At this time, if the door and pillar do not fit in the proper positions, the opening and closing of the door is hindered, or the position of the drop rod does not match, etc., keep the door suspended and use the lower hinge to move the door forward and backward. It is necessary to adjust the position. In the case of gate hinges,
It is said that the width of this position adjustment needs to be adjusted to be relatively large as compared with a door such as a normal entrance.

In order to solve such a problem, there is a gate hinge for which the position can be adjusted after the door is suspended.
000-226977, JP-A-7-317474, JP-A-8-151881, and JP-A-8-199890. In the parts common to all the mechanisms reported above, a case metal fitting having a portion where the blade portion of the arm body fits is provided, and a female screw portion is provided in the left-right direction inside the blade portion of the arm body. The left and right adjustment screws whose head positions are held from the end opposite to the shaft center side are screwed into the female threaded parts, and the left and right adjustment screws are turned to gradually move the position to adjust the position. One of the points is that it is used for the basic movement of left and right movement.

Similarly, for the adjustment in the front-back direction, a female screw portion is provided in the front-rear direction at a position near the axis of the blade portion, and the front-rear adjustment screw is screwed while holding the head position from the front of the case fitting. Most of the methods have been completed by rotating the front-rear adjustment screw to perform front-rear adjustment by swinging in the front-rear direction, with the position where the head of the left-right adjustment screw is held by the case metal fitting as the fulcrum. At the stage, fix the arm body from above and below the case fitting with the fixing screw.

Further, in order to prevent the door itself from being stolen, there has been conventionally provided a retaining means for preventing the upper hinge attached to the door side from coming off from the shaft center even if the door is lifted and then lifted. Generally, a recessed portion is provided on the upper side surface of the shaft core, a female thread portion is provided on the side surface of the pipe part of the upper hinge, and the removal prevention screw is screwed into the female thread portion from the outside to remove the tip of the removal prevention screw. In many cases, it is prevented from coming off by inserting it into the recess of the shaft core.

[0006]

However, in the above description, in order to provide the female screw portion for the left and right adjusting screws inside the blade portion of the arm body, it is necessary to make the blade portion considerably thick. Therefore, in many conventional products, the arm body is manufactured by die casting. Further, in the front-back adjustment, it is necessary to provide an extra space for the front-back movement of the arm body in the case fitting in order to swing the blade portion back-and-forth. Therefore, the case fitting becomes thicker in the thickness direction, lacks compactness, and is disadvantageous in terms of design.

Further, the adjustment hinge for the gate requires a lateral adjustment width of about 3 to 4 times, which is much larger than the adjustment hinge for the entrance, etc., and the adjustment adjustment is performed by the rotation of the adjustment screw. In this method, since the distance required for movement is pushed and pulled by the screw as it is, when the pitch of the screw thread is small, it is necessary to rotate the left and right adjustment screws many times when adjusting the maximum movement, which is inevitable. The problem is that it takes time. In addition, if the pitch of the screw threads is increased, the screw diameter is naturally increased and the thickness of the vane portion must be further increased.

In the fixing means of the arm body, there is a space for front-back adjustment between the blade portion of the arm body and the case fitting, and since the front and rear surfaces are in a floating state, the blade portion and the case fitting are in contact with each other. Many methods are used to secure the upper and lower surfaces only, but this fixing means has a small contact surface, making it difficult to obtain a strong holding force, which may cause looseness or rattling during use. There are many. Further, in the above-mentioned retaining means of the upper hinge, it is relatively difficult as a process to form a hole in the side surface of the pipe portion and to provide an internal thread portion, and when the wall thickness of the pipe portion is thin, very short removal prevention Except for using screws, the head is exposed,
There is a point that it is not preferable in terms of design.

The present invention has been made in order to solve the above problems, and has a left-right adjustment mechanism which can obtain a large adjustment range in an instant operation and can also be finely adjusted, and a front-back movement of an arm body. Is equipped with a front-rear adjustment mechanism with a smaller space, and can be firmly fixed after adjustment.
It is an object to provide an adjustment hinge for a gate, which has a thin thickness, is compact, and is excellent in design.

[0010]

In order to achieve the above object, the present invention has the following technical means. A tube portion into which the shaft core is inserted, an arm body including a flat blade portion, and a case metal member having a U-shaped portion in a U-shape in a side view are provided. Female screws for left and right fixing screws are provided above and below the central position of the blade portion of the arm body, and a vertical protrusion and a horizontal slot are provided on the front surface of the U-shaped portion of the case fitting. Next, insert the blade part of the arm body into the U-shaped part of the case fitting so as to wrap the upper and lower ends of the blade part,
The arm body is configured to move only in the left-right direction that is parallel to the door surface with respect to the case fitting, and the left and right fixing screws are screwed into the female threads for the left and right fixing screws of the blade part through the long holes of the case fitting. Assemble both.

The state where the heads of the left and right fixing screws are located at the center position of the elongated hole of the case fitting is the reference position in the left and right direction,
In this state, the heads of the left and right fixing screws and the protrusions are arranged in a line in the vertical direction. At this time, it is preferable to attach spring washers to the left and right fixing screws. Further, the configuration opposite to the above may be adopted in which the elongated hole and the protruding portion are provided in the blade portion of the arm body and the female screw portions for the left and right fixing screws are provided in the case fitting.

Next, it is an elongated plate-like member having a groove portion having a fixed length and a width capable of simultaneously fitting the heads of the left and right fixing screws and the protrusion portion at one end, and the grip portion at the other end. Install the adjusted jig. The width of the groove portion is made slightly wider than the diameter of the head portion of the protruding portion and the left and right fixing screws, and the length thereof is set to be somewhat longer than the distance between the head portion of the left and right fixing screws and the protruding portion.

When the left and right fixing screws are loosened in the above-mentioned configuration, the groove portions of the adjusting jig are simultaneously fitted into the heads and the projecting portions of the left and right fixing screws, and the grip portion is moved in the left and right direction. Rotational motion is achieved with either one of the screw head and the protrusion as a fulcrum, and the other side is pushed and pulled by the side surface of the groove in the left-right direction. This action is a lever action depending on the ratio of the distance between the head of the left and right fixing screws and the protrusion and the distance between either one of the fulcrum and the hand grip, and the arm body is moved left and right with a very light force. be able to. Therefore, the movement distance in the left-right direction is determined by the rotation angle of the adjustment jig, and it is possible to instantly move to any position with one operation, and it is also sufficient for fine adjustment by slightly moving the adjustment jig. It will be possible to respond. After adjustment, it can be easily fixed by turning the left and right fixing screws while holding the grip part, and it can be firmly fixed by tightening the left and right fixing screws when the surface of the case fitting and the surface of the blade part are in close contact. Become.

Further, there is provided a base metal fitting having a rectangular plate-like convex rib at the upper and lower central positions and having a plurality of female screw portions for front and rear adjusting screws on both sides sandwiching the rib. Further, a collar surface and an L-bent portion which is bent at a right angle from both ends of the collar surface are provided at the upper and lower positions of the U-shaped portion of the case fitting, and a front and rear adjusting screw insertion hole is provided in the collar surface. Put the front and rear adjustment screws through the front and rear adjustment screw insertion holes from the front so that the inside of the flange of the case metal and the tip of the rib of the base metal are in contact with each other, and the upper and lower ends of the base metal are covered by the L-bent portion of the case metal. Assemble by screwing into the female thread for the front-rear adjustment screw.

A state in which the case fitting and the base fitting are parallel to each other is a reference position in the front-rear direction. By loosening or tightening the front-rear adjusting screws located on both sides of the rib,
The seesaw motion of the case fitting and the arm body with respect to the base fitting with the rib as a fulcrum can be obtained, and the front-back adjustment can be performed. Therefore, the left-right adjustment and the front-back adjustment can be independently operated, and even in fixed work, they do not interfere with each other's adjustment and can be selected and executed separately.

The total thickness is the sum of the thickness of the base metal fitting including the rib and the thickness of the U-shaped portion of the case metal fitting including the blade portion. The blade portion is manufactured by winding a plate material. It can be as thin as a normal hinge, and can be made thin and compact overall.

In the retaining means of the upper hinge, a retaining screw is provided, a female thread portion having a constant depth is provided on the upper surface of the shaft core fixed to the lower hinge, and an upper portion of the pipe portion of the upper hinge is provided. Provide a stepped hole. The diameter of the upper part of the stepped hole is set to be larger than the diameter of the head of the slip-out prevention screw, and the diameter of the lower part is set to such a size that the male screw portion of the slip-out prevention screw can barely be inserted. Insert the pipe part of the upper hinge attached to the door into the shaft core of the lower hinge attached to the pillar of the gate, and in the state where the door is suspended, pass through the stepped hole and attach the pull-out prevention screw to the top of the shaft core. Fully screw into the female thread. In this state, the head of the slip-out prevention screw is arranged at the intermediate position in the depth direction of the upper diameter part of the stepped hole, so even if the slip-out prevention screw is completely tightened, it does not affect the opening and closing of the door. Without
Moreover, when the upper hinge is lifted together with the door, the stepped surface of the stepped hole comes into contact with and engages with the collar portion of the slip-out preventing screw, so that the slip-out preventing action is obtained.

With the above-mentioned structure, the left and right directions can be instantly adjusted largely and finely by one operation, and the arm body can be firmly fixed to the case fitting. It prevents misalignment and rattling, and can perform left-right adjustment, front-rear adjustment, and fixing work without interfering with each other.The overall thickness is thin, compact, and has excellent designability. It is possible to provide the adjustment hinge for the gate that the user has.

The lower hinge 34 including the movement adjusting mechanism is shown in FIGS.
As shown in FIG. 3, an arm body 1 including a shaft core 4, a tube portion 2 into which the shaft core 4 is inserted, and a flat blade portion 3,
A case fitting 5 having a U-shaped portion 6 having a U-shape in a side view is provided, and female screw portions 11 for left and right fixing screws are provided at two upper and lower central positions of the blade portion 3 of the arm body 1, and A vertical protruding portion 8 is provided on the front surface 9 of the V-shaped portion, and horizontal elongated holes 7 are provided at two vertical positions of the protruding portion 8. Further, a collar surface 21 having a plurality of front and rear adjusting screw insertion holes 19 is provided at both upper and lower ends of the U-shaped portion 6 and is parallel to the U-shaped portion front surface 9, and pin insertion holes 24 are further provided at both ends of the collar surface 21. The L-bent portion 22 having a right angle is provided.

The inner dimension of the U-shaped portion 6 of the case fitting 5 in the vertical direction is set to be slightly larger than the outer dimension of the blade portion 3 of the arm body 1 in the vertical direction. Is inserted into the U-shaped portion 6, the left and right fixing screws 10 are screwed from the direction of the front surface 9 of the U-shaped portion through the elongated hole 7 into the female screw portions 11 for the left and right fixing screws of the blade portion 3, and both are assembled. As shown in FIG. 1, left and right fixing screws 10 at two upper and lower positions
Is the reference position in the left-right direction, and in this state, the head of the left-right fixing screw 10 and the protrusion 8
Is configured so that it becomes a straight line in the vertical direction.

Next, as shown in FIG. 4, the head portion of the left and right fixing screws 10 is vertically elongated and has a width slightly larger than the diameters of the left and right fixing screws 10 and the protruding portion 8 at one end. It has a groove portion 14 which is longer than the distance at which the projection portion 8 and the projection portion 8 can be fitted at the same time, and the grip portion 1 is provided at the other end.
An adjustment jig 13 having 5 is provided.

FIG. 5 shows a state where the arm body 1 is adjusted to the reference position and right and left. FIG. 5 (a) shows the reference position, and when adjusting, either the left or right fixing screw 10
The groove portion 14 of the adjusting jig 13 is fitted into the head portion and the protruding portion 8 at the same time. When the left and right fixing screws 10 are loosened from this state and the grip 15 of the adjusting jig 13 is moved in the left and right direction, the adjusting jig 13 makes a rotational movement with the protruding portion 8 as a fulcrum, and The operation of pushing the side surface of the head with the side surface of the groove portion 14 is obtained. The left and right fixing screws 10 are screwed into the left and right fixing screw female thread portions 11 of the blade portion 3,
Since the blade portion 3 is restricted by the U-shaped portion 6 of the case fitting 5 to be movable only in the left-right direction, the arm body 1 is moved in the left-right direction as shown in FIGS. 5 (b) and 5 (c). It becomes possible. 5B shows a state in which the adjustment is made to the maximum in the left direction and FIG. 5C in the right direction, and the adjustment width can be arbitrarily set by changing the distance of the long hole 7.

The operation by the rotation of the adjusting jig 13 is a lever action depending on the ratio of the distance between the protrusion 8 serving as a fulcrum and the heads of the left and right fixing screws 10 and the distance between the protrusion 8 and the grip portion 15. Therefore, it is possible to move the arm body 1 with a very light force. Further, by moving the handgrip portion 15 at once, it is possible to instantaneously move it to the maximum adjustment position, and by slightly moving the adjustment jig 13, fine adjustment can be sufficiently performed. Left and right fixing screw 10
By arranging the two in the upper and lower parts, it becomes possible to adjust by the protruding portion 8 located at the center and the heads of the left and right fixing screws 10 of both the upper and lower parts. When the operating position is high, the handgrip part 15 of the handgrip part 15 faces upward as shown in FIG. 5 (c).
A more comfortable adjustment operation can be obtained by making the point downward.

Further, the adjustment hinge for the gate needs to have a larger adjustment width than the adjustment hinge for the entrance door and the like, and in order to make it easy to see the moving distance at that time, FIG.
As shown in (c), it is advisable to set a scale in the horizontal direction on the edge of the elongated hole 7 with the state of FIG. 5 (a) as the reference position. The moving distance can be sufficiently judged by reading the center position of the head of the left and right fixing screws 10 on the side not covered by the adjustment jig 13, and this is particularly effective for fine adjustment.

The case fitting 5 and the blade portion 3 of the arm body 1
In fixing the above, the inner surface of the U-shaped portion 6 of the case fitting 5 and the flat blade portion 3 are brought into close contact with each other and completely tightened with the left and right fixing screws 10, and the left and right fixing screws 10 are provided at the upper and lower positions. Is advantageous in that the arm body 1 can be more firmly fixed to the case fitting 5, and the holding force can be further increased by incorporating the spring washers 12 in the left and right fixing screws 10.

FIG. 6 is a front view showing a state in which the gate adjustment hinges of the first embodiment are mounted at two positions above and below the gate. From this state, the left and right fixing screws 10
It is conceivable that if the door is loosened significantly, the momentary force acts in the direction of the arrow in FIG. 6 due to the weight of the door 35, and the door 35 suddenly moves to the maximum adjustable position and tilts. Therefore, at the time of adjustment, be sure to insert the adjustment jig 13 and hold the adjustment jig 13 by hand to fix the left and right fixing screws 1
It is necessary to loosen or tighten 0.

Therefore, the left and right fixing screws 10 are not completely loosened at the time of left and right adjustment, but are loosened to such an extent that the hanging of the door 35 due to its own weight can be stopped by the frictional force of the spring washer 12 incorporated in the left and right fixing screws 10 described above. Good. Further, if the length of the grip portion 15 is appropriately set according to the weight of the door 35 and the movement adjustment operation by the adjustment jig 13 is made possible with a light force, the hand is released from the adjustment jig 13 during the adjustment. However, the door 35 will be held at that position, and the adjustment operation will be easier.

Next, as shown in FIGS. 1 to 3, there are rectangular plate-shaped ribs 17 having a convex shape in the vertical direction of the central position, and a plurality of female screw portions 20 for front and rear adjusting screws on both sides sandwiching the rib 17. The base metal fitting 16 provided with is provided. Base metal fittings 16
The upper and lower ends of the case metal fitting 5 are covered with the L-bent portions 22, and the front and rear adjusting screws 18 are provided on the collar surface 21 with the inner surfaces of the upper and lower brim surfaces 21 of the case metal fitting 5 being in contact with the tips of the ribs 17 of the base metal fitting 16. Through the front-rear adjusting screw insertion hole 19, it is screwed to the front-rear adjusting screw female thread portion 20 of the base fitting 16.

FIG. 7 is a top view showing the front-back adjustment.
(a) shows a reference position state in the front-rear direction in which the base metal 16 and the collar surface 21 of the case metal 5 are parallel to each other. From this state of FIG. 7 (a), by loosening or tightening the front and rear adjustment screws 18 located on both sides of the rib 17,
The seesaw motion of the case fitting 5 and the arm body 1 with respect to the base fitting 16 with the rib 17 as a fulcrum can be obtained, as shown in FIG.
Also, as shown in FIG. 7C, it is possible to adjust the shaft core 4 back and forth. Further, with the L-shaped bent portion 22 covering the base metal fitting 16, the pin 23 is inserted into the pin insertion hole 24 at the central position of the L-shaped bent portion 22, and the thick portion of the rib 17 is connected to the inner surface of the collar surface 21 of the case metal fitting 5 and the pin 23. By sandwiching between the case metal fitting 5 and the base metal fitting 16 even if the front and rear adjusting screw 18 is extremely loosened, the case metal fitting 5 and the base metal fitting 16 can be prevented from coming off, and a smoother front and rear adjusting operation can be obtained.

The arm main body 1 is not in direct contact with the base metal fitting 16, and the left and right adjustments and fixings are made only by the case metal fitting 5 and the arm main body 1, and the front and rear adjustments and fixings are made only by the base metal fitting 16 and the case metal fitting 5. Can be carried out in
It is possible to select and perform the left-right adjustment, front-rear adjustment, and fixing work without interfering with each other.

As shown in FIG. 3, the overall thickness of the lower hinge 34 having the adjusting mechanism in the first embodiment is the thickness of the base metal fitting 16 including the rib 17 and the thickness of the case metal fitting 5 including the blade portion 3. This is the total thickness of the U-shaped portion 6. Further, as shown in FIG. 7, the front-rear adjustment is a seesaw motion with the rib 17 positioned at the center of the base metal member 16 in the width direction as a fulcrum, so that a small space is required and the height of the rib 17 can be relatively low. The blade portion 3 may have a plate thickness of a hinge for winding a normal plate material, and can be made extremely thin and compact as a whole.

Contrary to the first embodiment, a configuration in which the elongated hole 7 and the protruding portion 8 are provided on the blade portion 3 of the arm body 1 and the female screw portions 11 for left and right fixing screws are provided on the case fitting 5 is shown as a second embodiment. 8 shows. Replace the U-shaped part 6 with the plate-shaped case fitting 5
Is formed by a bent portion in the right angle direction, and the flange surface 21 is flush with the surface of the case fitting 5. In the second embodiment, when the adjustment jig 13 is fitted and the handgrip portion 15 is rotated, the fulcrum is the head of the left and right fixing screws 10, and the side surface of the protruding portion 8 provided on the blade portion 3 is grooved. Since it is pushed by the side surface of 14, the left and right adjustment of the arm body 1 becomes possible in the same manner. For the front-back adjustment, the same configuration as that of the first embodiment can be incorporated, the overall thickness is further thin and compact, and the position of the shaft core 4 is located farther from the surface of the column 36 than in the first embodiment. Points are mentioned as a feature.

In both the first and second embodiments, the pillar 36 is used.
The base metal fitting 16 and the back plate 26 arranged inside the pillar 36 are sandwiched between the base metal fitting 16 and the base metal fitting 16 and fixed with a mounting screw. It is advisable to provide holes at the portions where the tips of the front-rear adjusting screw 18 and the left and right fixing screws 10 project to the columns 36 so as to allow them to escape.
After the adjustment is completed, if the decorative cover 25 is attached to the entire case fitting 5 of the lower hinge 34, the design can be further improved.

The lower hinge 34 attached to the pillar 36 is only for left and right adjustment, and a similar adjustment mechanism is attached to the upper hinge 33 attached to the door 35 as a third embodiment, which is shown in FIG. As shown in FIGS. 2 and 9, when the door 35 is closed, the blade hinges 3 are positioned at right angles to each other, and the upper hinge 33 mounted on the thickness surface of the door 35 is adjusted in the same manner. When the mechanism is provided, the movement direction by the adjustment of the upper hinge 33 becomes the front-back direction, that is, the front-back adjustment can be performed as it is. The adjustment width of the front-to-back adjustment may be relatively smaller than that of the left-to-right adjustment, so that the case metal fitting 5 that constitutes the upper hinge 33 is formed.
Also, the lateral dimension of the long hole 7 may be small,
It is considered that the adjusting mechanism portion can be sufficiently stored in the thickness direction surface of the door 35. The overall thickness can be made thinner because the thickness of the base metal fitting 16 and the space for the seesaw movement can be eliminated, and it is also advantageous when attached to the upper hinge 33, and is more compact and excellent in design. Can be configured. However, in the third embodiment, the front-rear adjustment is performed on the thickness direction surface of the door 35, and therefore it is necessary to operate the door 35 with the door 35 opened at 90 ° during the adjustment.

Next, a means for preventing the upper hinge 33 from coming off is shown in FIG.
It shows in 0. The shaft core 4 is fixed to the lower hinge 34, and the upper surface 30 of the shaft core is provided with a female screw portion 31 for a slip-out preventing screw having a constant depth. Further, a stepped hole 27 is provided at the upper end of the tube portion 2 of the upper hinge 33. In the hinge formed by winding the plate material, it is preferable to provide the step star with a stepped hole 27 and fix the star to the upper end of the tube portion 2. Regarding the shape of the stepped hole 27, the upper part has a diameter larger than the head diameter of the slip-out prevention screw 28, and the lower part has a diameter such that the male screw part of the slip-out prevention screw 28 can barely be inserted. The depth of the diametrical part is set to be much deeper than the height of the head of the slip prevention screw.

Lower hinge 3 attached to the gate pillar 36
4, the tube portion 2 of the upper hinge 33 attached to the door 35 is inserted into the shaft core 4, and the withdrawal prevention screw 28 is passed through the stepped hole 27 while the door 35 is suspended, and the shaft core upper surface 30 is prevented from coming off. It is completely screwed into the internal thread portion 31 for the screw. In this state, by setting the head of the slip-out prevention screw 28 to be located at the intermediate position in the depth direction of the upper diameter portion of the stepped hole 27, the slip-out prevention screw 28 does not come into contact with the upper hinge 33 at all. Therefore, opening / closing of the door 35 is not affected.

When the door 35 is lifted from the state shown in FIG. 10,
The upper hinges 33 come out of the shaft core 4 and try to come off, but when the stepped surface 29 of the stepped hole 27 comes into contact with the collar portion of the coming-out prevention screw 28, they are locked with each other and the coming-out prevention is performed. Since the screw 28 is completely screwed into the shaft core 4, the upper hinge 3
3 can be prevented from coming off, and the door 35 will not come off. Further, since it is possible that the stepped hole 27 of the upper hinge 33 remains as a recess and rainwater or the like enters, the removal prevention screw 2
After inserting 8, the stepped hole 27 may be covered with a resin cap 32 or the like. It is considered that the above-mentioned configuration is possible only by processing the stepped hole 27 of the star and the processing of the female screw portion 31 for the slip-out preventing screw on the upper surface 30 of the shaft, and the manufacturing is easy and can be implemented at low cost.

As described above, the arm body can be adjusted in the left-right direction by a simple operation of moving the grip portion of the adjustment jig, and the adjustment width can be arbitrarily set by changing the distance of the long hole. You can Further, since the operation of rotating the adjusting jig acts as a lever, it is possible to move the arm main body with a very light force. Furthermore, by moving the grip part at once, it is possible to instantaneously move to the maximum adjustment position, and by slightly moving the adjustment jig, fine adjustment can be sufficiently performed. It is possible to easily judge the moving distance by grading the edge of the long hole in the left-right direction and reading the center position of the head of the left and right fixing screws with the graduation, which is particularly effective for fine adjustment.

Since the inner surface of the U-shaped portion of the case metal fitting and the flat blade portion of the arm body are brought into close contact with each other and completely tightened by the two right and left fixing screws, a strong washer can be obtained, and a spring washer is attached to the left and right fixing screws. When incorporated, the holding power is further enhanced. Also, by incorporating a spring washer, it is possible to stop the drooping due to the weight of the door with the frictional force of the spring washer without completely loosening the left and right fixing screws during adjustment.
In addition, it is possible to make adjustments by the adjustment jig by setting the length of the grip part appropriately, and it is easier to hold it at that position even if you release your hand from the adjustment jig. It is possible to obtain various adjustment operations.

By providing the base metal fittings, the front and rear adjustments can be made by the seesaw movement of the case metal fittings and the arm main body with respect to the base metal fittings with the rib as a fulcrum, only by loosening or tightening the front and rear adjusting screws. Since the front-rear adjustment and each fixed operation do not interfere with each other's adjustment, all the operations can be separately selected and performed.

The total thickness is the sum of the thickness of the base metal fitting including the ribs and the thickness of the U-shaped portion of the case metal fitting including the blade portion of the arm body, and the blade portion is as thick as a normal hinge. It is good, it can be made thin and compact as a whole, and it has excellent design.
