Description

Pivot hinge attached to the panel}

The present invention relates to a panel mounting pivot hinge, and more particularly, to a panel mounting pivot hinge to support the door using a horizontal support bar extending horizontally from the bottom of the fixed panel toward the lower portion of the door.

In general, the bathrooms are finished with tiles or other interior materials to partition the space by using partitions, and the partitions were installed by raising the partition to a certain height from the floor surface by using a supporter to facilitate water cleaning.

In addition, the door installed in the partition was configured to support the opening and closing using a shaft-type hinge and a bottom fixed pivot hinge configured to be supported on the upper frame and the bottom surface, respectively.

The conventional bottom fixed pivot hinge is formed with a flange portion 14 fixed to the bottom surface 12 by a screw 11, as shown in the accompanying drawings, Figures 1 to 4, the flange portion 14 A support portion 10 having a threaded portion 16 formed vertically from the center thereof, and having an inclined surface 18 formed on an upper end of the threaded portion 16;

A pivot shaft 20 having an inclined sliding surface 22 sliding in contact with an inclined ground surface 18 formed at an upper end of the support 10 and having a serration portion 24 formed at an upper end thereof. and;

A 'L' shaped clamp 40 coupled to the serration part 24 formed at the upper end of the pivot shaft 20 and fixed to the lower portion of the door 30;

A guide tube 50 screwed to the threaded portion 16 and configured to guide the pivot shaft 20 to be rotated horizontally;

The pivot shaft 20 and the threaded portion are inserted into a hole 18a formed to protrude downward from the lower end of the pivot shaft 20 and formed downwardly from the center of the inclined surface 18 of the screwed portion 16. A center pin 26 which allows the centers of the 16 to coincide with each other;

A cap 55 covering the lower portion of the flange portion 14 and the guide tube 50;

It consisted of the bolts 60 and 62 and the nut 64 which connect the said clamp 40 and the door 30. As shown in FIG.

When the conventional bottom-fixed pivot hinge is opened when the door 30 is opened, the inclined sliding formed at the lower end of the pivot shaft 20 while the clamp 40 and the pivot shaft 20 move together with the door 30 to be opened. The surface 22 slides from the inclined surface 18 formed at the upper end of the threaded portion 16, with the pivot shaft 20 being slightly raised upward along the inclined surface 18 of the threaded portion 16. When the external force was removed from the 30, the door 30 was always configured to receive a force in the closing direction.

That is, even if the door 30 is not forcibly closed, the pivot shaft 20 slides to a position where the lowest part of the inclined sliding surface 22 meets the lowest part of the inclined surface 18 due to gravity applied to the door 30. It was configured to close automatically.

1 to 4, reference numeral 34 denotes a reinforcing frame attached along the edge of the door 30, and 46 is formed on the fixing member 40 so that the serration part 24 is inserted. 58 shows a through hole, 58 shows a through hole formed in the upper end surface of the guide tube 50 so that the serration part 24 is exposed upward, and 19 is formed in the flange part 14. The fastening hole penetrating the screw 11 is shown, and 36 is a supporter for supporting the fixing panel 32.

However, since the conventional floor-mounted pivot hinge is configured in such a manner as to be fixed to the bottom surface 12 which is relatively weak to impact, the strong impact applied to the door 30 in the process of opening and closing the door 30 is flanged. The cracks are generated on the bottom surface 12 while being transmitted to the screw 11 embedded in the 14 and the bottom surface 12, and eventually the door 30 is rattled. Since it was a way to directly fix the fixed panel 32 and the door 30 had a difficulty in constantly matching the gap.

That is, the position where the pivot shaft 20 is installed is selected on the bottom surface 12, and then the flange portion 14 is installed on the bottom surface 12. At this time, if the bottom surface 12 is uneven, the fixing panel 32 ) And the gap between the door 30 was not constant.

In addition, since the cap 55 which covers the flange portion 14 and the guide tube 50 is not fixed but is simply installed on the flange portion 14, the door 30 is opened and closed. In the process, while shaking by the vibration transmitted to the cap 55 had a problem of generating noise while hitting the bottom surface 12, the flange portion 14, the guide tube 50.

In addition, the door 30 has bolts 60 and 62 and nuts 64 coupled through two through-holes 42 and 44 formed in the clamp 40 having an 'L' shape. It was configured to be fixed by but is particularly vulnerable to the force acting in the transverse direction to the door 30, and as time passes, the gap between the clamp 40 and the door 30 to make a gap generated noise or the door (30) Had a problem tilted to one side.

The present invention has been made to solve the above problems, the purpose of which can prevent the occurrence of cracks on the bottom surface by the impact generated in the process of opening and closing the door and at the same time prevent the rattling of the door. In the process of installing the door, the gap between the door and the fixed panel can be made more convenient, and the noise generated by shaking caused by the vibration generated during the opening and closing of the door can be prevented, and between the door and the pivot hinge To provide a panel mounting pivot hinge that can further strengthen the structural strength.

In order to achieve the object of the present invention, a part of the horizontal support bar is fixed in close contact with the bottom of the fixed panel and extends horizontally toward the bottom of the door, and the horizontal support bar and the fixed panel in close contact with the horizontal support bar and the fixed panel The shaft is fixed to the upper surface of the horizontal support bar and the panel fixing plate for connecting the screw hole which is inserted into the vertical hole formed in the bottom surface of the fixed panel and screwed to the screw penetrating the fixed panel is formed in the direction perpendicular to the shaft A door support plate having a cross section cam installed on one side of the horizontal support bar by a fixing means and having an inclined surface and a pivot hole formed thereon, and a pivot shaft fixed to the bottom of the door and inserted into the pivot hole; And a locator pin which is installed laterally from the pivot shaft and slides on the inclined surface.

The panel fixing plate 82 which is in close contact with the front surface of the 80 and the fixed panel 70 and connects the horizontal support bar 80 and the fixed panel 70, and is fixed to the upper surface of the horizontal support bar 80 The shaft 90 is inserted into the vertical hole 74 formed in the bottom surface of the fixing panel 70 and the screw hole 92 screwed with the screw 84 penetrating the fixing panel 70 is formed in the direction perpendicular to the shaft. And a cross-section cam 110 installed on one side of the horizontal support bar 80 by the fixing means 100 and having an inclined surface 112 and a pivot hole 114 formed thereon, and the door 72. And a door support plate 120 having a pivot shaft 122 inserted into the pivot hole 114 and the pivot shaft 122. Is provided with emitter transverse was composed of the locate pin 124 to slide from the inclined surface 112.

The locate groove 116 to which the locate pin 124 is formed is formed at the lowest portion of the inclined surface 112 of the end face cam 110 so as to more accurately position the door 72 when the door 72 is closed. .

In addition, the locator groove 116 may be formed in, for example, a hemispherical shape, but is not necessarily limited to such a shape or shape, and may also be configured as a 'V' shaped groove or a square shape.

Annular grooves 94 and 96 for injecting the adhesive 130 to the outer circumference of the shaft 90 are further formed to form the shaft 90 in the vertical hole 74 formed in the fixing panel 70. When the adhesive 130 is injected into the annular grooves 94 and 96 before insertion into the annular grooves 94 and 96, the hardening is hardened and configured to increase the bonding force.

The fixing means 100 forms a threaded portion 102 at the lower side of the end face cam 110, and the horizontal support bar 80 has an otoscope hole having a jaw that is caught by the end face cam 110 from the upper side to the lower side. Formed (86) was configured to be fixed by screwing to the threaded portion 102 through the nut 88 in the lower side of the horizontal support bar (80).

The horizontal support bar 80 is configured to be in a stepped shape with the middle facing downward so that the portion supporting the door 72 is lower than the portion attached to the fixing panel 70.

The side of the horizontal support bar 80 is formed with a screw hole (89a) (89b) for fixing the panel fixing plate 82, a vertical through hole (89c) for fixing the shaft 90 in the center Formed.

A plurality of fastening holes 128 are formed in the door support plate 120.

In the drawings, reference numerals 150, 152, 154, and 156 denote screws.

Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.

5 to 9, when the door 72 is opened, the door support plate 120, the pivot shaft 122, and the locate pin 124 move simultaneously with the door 72 to support the door 72. It is rotated while being horizontally guided by the diameter hole 86 of the end face cam 110 fixed to the bar 80.

At this time, as the locate pin 124 slides upward on the inclined surface 112 formed at the upper end of the end face cam 110, the door 72 is slightly lifted upward.

Then, when the external force is removed from the door 72, the locate pin 124 rides on the inclined surface 112 toward the lowest point of the inclined surface 112 by the force acting by the own weight of the door 72. The door 72 automatically closes as it slides.

When the locate pin 124 reaches the locate groove 116 formed on the inclined surface 112, the locate pin 124 is caught by the locate groove 116 and maintains the closed state of the door 72. 72 can be accurately determined the closed position.

Meanwhile, when the door 72 is opened and closed, the horizontal support bar 80 supporting the end face cam 110 is fixed to the bottom of the fixed panel 70 and the fixed panel 70 is supported on the bottom surface. Will be able to guide the door 72 in a fixed state.

In addition, the force acting in the process of opening and closing the door 72 is fixed vertically to the horizontal support bar 80, the shaft 90 and the horizontal support bar 80 is inserted into the inside of the fixed panel 70 and It is firmly held by the panel fixing plate 82 which connects the fixed panel 70.

Furthermore, since the door support plate 120 moving together with the door 72 is installed on the bottom surface of the door 72, the door support plate 120 can be firmly supported even in the force acting in the lateral direction.

When the closed position of the door 72 is shifted, when the position of the door 72 is corrected while loosening the nut 88 fixing the end face cam 110, together with the door 72 to be corrected. In addition to the door support plate 120, the locate pin 124 is moved along, and the position is corrected while the pivot shaft 122 is also moved by the locate pin 124.

When the nut 88 that has been loosened is then tightened again, the pivot shaft 122 is fixed and not moved, and stops at the corrected position when the door 72 is closed.

That is, since the locate pin 124 is caught in the locate groove 116 formed in the pivot shaft 122, the pivot shaft 122 moves along the locate pin 124 when calibrating. When the shaft 122 is rotated and the angle is changed, the position of the locate groove 116 is also changed, and thus the position at which the door 72 is stopped is changed.

The present invention as described above has a structure in which the lower part of the door is indirectly supported by the fixing panel instead of being directly supported on the bottom surface, so that vibrations or shocks generated during the opening and closing of the door directly on the floor surface. Since it is not transmitted, it is possible to prevent cracks that may occur on the bottom surface, and to prevent the rattling of the door that may occur due to this phenomenon. In addition, the gap between the door and the fixing panel can be more conveniently made, and the use of the cap as in the past can be eliminated, thereby preventing the noise generated during the opening and closing of the door. The door and pivot hinge or fixed by the shaft, panel fixing plate, door support plate Because it is configured to be able to further enhance the structural strength between the board and the pivot hinge, there is an effect that it is possible to extend the life.
