Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a technique for correcting the installation of a door by adjusting the position in the width direction of the door in a rotary open / close door provided with a storage box such as a locker or a book shelf, or a hinge used for a window or a doorway.
[0002]
[Prior art]
When attaching a hinged door to a mounting member such as a side wall, there may be a gap or inclination in the mating surface on the opening and closing side of the other door or door frame, or the hinge part may be deformed due to long-term use. In some cases, the opening / closing side mating surface of the door may be out of order, and it is necessary to adjust the position of the door in the width direction to correct the installation.
As a mechanism for adjusting the position in the width direction of the door, for example, a mechanism shown in FIG. 6 is conventionally known.
[0003]
FIG. 6 is a partial view showing the hinge part of the opening / closing door of the storage box in a cross-sectional view. The storage box 20 rotates the door 22 through the hinge member 24 to the front end of the opening side wall of the box body 21 opened on the front side. It shows a state where it can be opened and closed.
The hinge member in the figure has a resin plate 25 and a metal plate 26 that overlaps with the resin plate 25 along the plane of the resin plate on the side in contact with the door mounting member 23, and a resin on the tip side of the metal plate 26. It is the structure which has the pin mounting hole 29 of the direction along the board surface of a hinge in the board front-end | tip 24a. Then, the base end side is fastened and fixed to the end portion of the door mounting member 23 with a mounting screw 28 via a plate-shaped adjusting member 27, and the distal end portion 24a of the hinge member 24 protruding from the door mounting member end is on the door 22 side. It connects with the other party hinge member 31 fixed to the side edge part of this by the pin 30, and the door is comprised so that rotation is possible for this connection pin as a fulcrum.
[0004]
In the door 22 in FIG. 6, the position adjustment in the width direction of the door (the left-right direction in the figure) is performed by changing the thickness of the adjustment member 27. That is, several types of adjusting members 27 having different thicknesses are prepared in advance, and the door 22 is attached to the door mounting member 23, and the clearance between the door or the door frame on the opening / closing end side of the door 22 or the degree of inclination of the door. Then, after selecting an adjustment member having a thickness that matches the correction amount obtained as a result of the measurement, the mounting screw 28 is loosened to remove the hinge member 24 once, and the selected adjustment member having an appropriate thickness is used as the hinge member. The position of the door in the width direction is adjusted by a procedure of inserting between the mounting members and retightening and fixing with the mounting screws 28. Note that the tilt adjustment in this case can be handled by individually changing the thickness of the adjustment member inserted into the hinge member above and below the door.
[0005]
[Problems to be solved by the invention]
In the above conventional method, the clearance and inclination on the door opening / closing end side are measured with the door once received, and an adjustment member having a thickness that matches the required amount of position correction in the width direction of the door is attached to each hinge according to the degree. After each selection, the hinge part of the door is removed, the adjustment member for correction is attached, and the door is attached again. This adjustment may not be completed in a single operation. Therefore, a lot of work time and cost are required for the work of product assembly and subsequent adjustment.
[0006]
The problem to be solved by the present invention is an open / close door provided with a storage box such as a locker or a book shelf or a hinge used for a window or an entrance / exit, and the other door on the open / close end side of the door by adjusting the position in the width direction of the door It is another object of the present invention to provide a hinge mechanism that makes it possible to easily correct the gap and inclination with the door frame in a short time.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, a mechanism is possible in which the position of the pin of the rotation fulcrum of the hinge mechanism can be arbitrarily adjusted inward and outward by the adjusting means with the door attached.
[0008]
For this purpose, first, the hinge member is fixed to the door mounting member by inserting the base end side in contact with the door mounting member from the notch hole formed in the front end of the door mounting member, and the distal end side is along the hinge member plane. The pin is connected to the side end of the door through a pin mounting hole formed through the door, and the door can be opened and closed with the pin as a fulcrum.
[0009]
On the other hand, at the position of the notch hole of the hinge member, a screw hole is formed so as to penetrate the screw hole so that it is substantially orthogonal to the plane of the hinge member and partially overlaps the inner and outer ends of the notch hole in the door opening / closing direction. When the attached adjustment screw is moved forward or backward, the adjustment screw end contacts the outer end or inner end of the notch hole in the door opening / closing direction and presses against it, and the front end side of the hinge member is deformed, and the door It is configured to warp inward or outward.
[0010]
Alternatively, the hinge member is formed of a resin plate and a metal plate that is integrally overlapped with the resin plate along the plane of the resin plate from the base end side fixed to the door mounting member to a position slightly closer to the tip than the notch hole. And a pin mounting hole in the direction along the plate surface is formed at the front end of the resin plate extending from the metal plate to the front end side, and the hinge member is overlapped with the inner and outer ends of the notch hole in the door opening / closing direction. A screw hole penetrating the hinge member may be formed in a direction substantially orthogonal to the plate surface.
[0011]
Alternatively, in any of the above cases, the hinge member on the tip side from the notch hole is bent in a hook shape so as to face the outer end side of the door, and the pin in the direction along the plate surface of the hinge member at the tip of the hook portion A mounting hole may be formed, and a screw hole penetrating the hinge member in a direction substantially orthogonal to the plate surface of the hinge member may be formed so that the notch hole partially overlaps the inner and outer ends of the door opening / closing direction.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
A typical embodiment of the hinge mechanism according to the present invention is shown in FIG.
FIG. 1 is an enlarged view of a main portion on one side of a partial view in which the front opening / closing door portion of the storage box with double doors shown in FIG. In the figure, a storage box 19 has a box body 2 that opens on the front side, a door 3 that covers the opening, and a hinge mechanism 1 that connects the front end of the side wall of the box body and the side edge of the door 3. The door 3 connected by the pin 9 attached to the tip of the hinge member 5 of the mechanism 1 is shown attached to the pin 9 so that it can be rotated and opened.
[0013]
The hinge member 5 of the hinge mechanism 1 is bent in a bowl shape toward the flat base end portion 5a attached to the side surface of the box body 2 and the outside of the box body (that is, the right side in the figure on the side end side of the door). A pin-shaped member having a front end portion 5b having a shape, and a pin mounting hole 8 for mounting a pin 9 for connecting the door 3 in a direction along the plate surface is formed through the front end portion 5b. A bent portion 7a that bends inward toward the inside of the box is formed at the base of the bowl-shaped portion, while the hinge member 5 includes a member of the resin plate 6 extending from the proximal end to the distal end, and a bent portion 7a from the proximal end side. The metal plate 7 is formed so as to be slightly overlapped with the metal plate 7 along the plane of the resin plate 6.
[0014]
In FIG. 4, the detailed structure of the hinge member 5, the pin 9, and the pin support member 17 (that is, the counterpart member of the hinge member 5) fixed to the side end of the door 3 is shown in a perspective view. As shown in this figure, the hinge member 5 has a concave groove 16 having a width substantially the same as the width of the metal plate 7 in the longitudinal direction in the central portion of the resin plate 6 and projections 14 and 14 in the concave groove. The metal plate 7 is formed with through holes 15, 15 corresponding to the shape of the protrusions 14 at positions corresponding to the protrusions 14. When the metal plate 7 is mounted in the concave groove 16 of the resin plate 6, the protrusions 14 are formed in the through holes 15, the resin plate and the metal plate are integrated with each other, and a screw hole for attaching a mounting screw 13 (FIG. 1) to an appropriate position on the base end side vertical portion of the hinge member 5. 12 is formed by penetrating.
[0015]
On the other hand, in the vicinity of the bent portion 7 a of the hinge member 5, another screw hole 10 that penetrates the resin plate and the metal plate in a direction substantially orthogonal to the hinge member plane is formed so as to penetrate the screw hole 10. An adjustment screw 11 having flat surfaces 11a and 11b at the front and rear ends and a hexagon hole 11c for attaching a hexagon wrench at the rear end is screwed and attached in advance so that the front end faces outward.
[0016]
The relationship of the screw hole 10 will be described in detail in the description of the purpose of the adjusting screw 11 to be described later, but from the notch hole 4a formed at the front end of the door mounting member 4 (to be described later), the hinge member 5 is provided behind. In a state where the end is inserted and attached to the door attachment member, both ends of the adjustment screw 11 are formed at positions that partially overlap the inner and outer ends of the cutout hole 4a.
[0017]
The base end of the hinge member 5 is cut off at an angle as shown so that it can be easily inserted into the narrow notch 4a formed at the distal end of the door mounting member when it is mounted on the door mounting member 4 (described later). It is convenient to use a different shape.
[0018]
As shown in FIG. 1, the door mounting member 4 is a thin box-shaped door mounting portion formed by adhering and forming the extended end of the box member, the reinforcing member 4 </ b> A, the protective member 4 </ b> B, etc. A notch hole 4a having a flat inner and outer ends on the left and right sides is formed at the front end of the door mounting member 4.
[0019]
The hinge member 5 is inserted into the notch hole 4 a at the base end side 5 a and fixed to the reinforcing member 4 A in the door mounting member with the mounting screw 13, while the distal end portion 5 b protruding from the notch hole 4 a It connects with the other party member of the hinge adhering to a side end part, ie, pin support member 17, with pin 9. As a result, the door can be opened and closed with the pin 9 as a fulcrum.
[0020]
The purpose of the adjusting screw 11 is that when the adjusting screw 11 is moved forward or backward, the leading end 11a or the rear end 11b of the adjusting screw comes into contact with the outer end or inner end of the door mounting member in the door opening / closing direction. It is interposed as an adjusting means for deforming the vicinity of the bent portion 7a of the hinge member 5 by the reaction force that presses and the tip of the hinge member 5 warps inward or outward.
[0021]
Next, the operation of the hinge mechanism 1 having the above-described configuration, that is, the position adjustment in the width direction of the door will be described.
FIG. 5 is a partial view showing a cross section of the door and the hinge mounting portion of the storage box 19 with a double door, and the hinge mechanism according to the present invention described on the basis of FIG. It is mounted symmetrically.
And in such a double door, in order to avoid interference between doors 3 and 3, it attaches so that the very slight clearance B may be left in the mutual mating face 18. FIG.
[0022]
However, due to manufacturing errors of storage boxes, doors or hinges, and mounting errors during assembly, the gap B may be too wide, the gap may be inclined up and down, or it may be too close and interfere. The defect must be corrected by adjusting the position in the width direction of the door.
[0023]
First, the door opening and closing end gap B is measured with the doors 3 and 3 attached to the box 2 via the hinge mechanism 1 of the present invention, and the upper and lower hinges of each door are determined from the difference between the size of the gap and the upper and lower gaps. The position of the position adjustment amount in the width direction of the door at the position of. When the door is opened and the adjustment screw 11 (see FIG. 1) of the hinge mechanism 1 is rotated based on the measurement result, the gap B can be adjusted in the following manner. In the following description, the symbols and names of the respective parts are the same as those in FIG.
[0024]
The adjustment screw 11 is rotated in the forward direction (outward of the door, diagonally to the right in FIG. 1), and the tip 11a is brought into contact with the door opening / closing direction outer end of the front end cutout hole 4a of the door mounting member 4 of the box 2. When the screw is further screwed in, the hinge member 5 is deformed at the distal end side 7a and warps inward, and accordingly the hinge member distal end 5b moves inward, so that the door 3 moves inward via the pin 9.
[0025]
On the other hand, when the adjustment screw 11 is rotated in the backward direction (inward of the door, diagonally to the left in FIG. 1), the rear end 11b is brought into contact with the inner end of the cutout hole 4a and further retracted. Since the hinge member tip 5b moves outwardly and deforms at the distal end side 7a, the door 3 moves outward via the pin 9.
[0026]
In the case of over-adjustment, when the adjustment screw 11 is reversed, the bent portion 7a is warped due to the elasticity of the hinge member 5, and the hinge member tip 5b moves to the initial state side accordingly, and the door 3 is also initialized via the pin 9. Move to the state side.
[0027]
That is, if the relative position difference between the right end of the door 3 and the right end of the door mounting member 4 formed at the front end of the box 2 is A1 (FIG. 1) at the time of assembly, the adjustment screw 11 is moved forward. When it rotates in the direction (outward, that is, in the right direction in FIG. 1), it gradually spreads to the state of A2 in FIG. 2, and conversely, it rotates in the backward direction (inward, that is, in the left direction in FIG. 1). 3 gradually narrows to the state of A3 in FIG. 3, so that the door 3 moves in the left-right direction in the figure and the gap B (FIG. 5) facing the counterpart door changes.
[0028]
When the adjustment screws 11 of the upper and lower hinge mechanisms of the left and right doors are sequentially adjusted in this manner, the door moves in the width direction, and the mounting position and inclination are either inside or outside within the movable range (adjustable range) of the adjustment screw 11. It is possible to arbitrarily adjust the direction.
[0029]
The amount of displacement of the hinge member tip 5b obtained by the turning operation of the adjusting screw 11 is slight, but the amount of movement required for adjusting the clearance and inclination of the door is about several millimeters (usually within about 5 mm). The amount of deformation of the hinge member (the amount of change in warping) may be small, and this adjustment does not affect the strength or durability of the hinge member 5.
[0030]
When the adjustment screw 11 is rotated as described above, the hinge member 5 rotates around the bent portion 7a so that the tip portion 5a swings its head, so that the pin 2 is moved from the front end of the box 2 and the front end portion of the door mounting member. The distance to the center of 9 also slightly changes, and accordingly, the distance between the inner surface of the door 3 and the front end portion of the box 2 and the door mounting member also changes.
[0031]
The amount of change in this distance is very small, but in the unlikely event that the door and the front end of the box interfere with each other, the resin plate on the hinge member tip side is bent into a bowl shape as shown in the figure. If it exists, the curvature of a bowl-shaped part will change a little in an opening direction easily, it will follow the amount of interference of the door 3 inner surface and the box 2 front end surface by the effect | action, and it will be possible to close a door comfortably.
[0032]
Since the screw hole 10 of the hinge member 5 is formed near the tip of the bent portion 7a and penetrating the metal plate tip and the resin plate, the front end of the box body 2 is inclined outwardly as shown in the figure. A notched hole 4a is formed in the front end slope of the expanding slope shape. By doing in this way, since the adjustment screw 11 is directed in the direction of the front end slope member in contact with the adjustment screw 11, the thrust of the adjustment screw can be increased in structural strength, and the hinge member can be moved when the adjustment screw is advanced and retracted. There exists an advantage which deform | transforms easily in the bending part 7a.
[0033]
The hinge mechanism of the present invention can have various shapes and forms, and is not limited to the above description and the drawings of the embodiments. Further, the hinge mechanism of the present invention can be implemented not only for the double door shown in FIG. 5, but also for a single door, although not shown.
[0034]
In the above description, the reason why the metal plate 7 is integrally attached along the base plane of the resin plate 6 of the hinge member 5 is that the hinge member is increased in rigidity, and the screw hole 12 for the attachment screw 13 or the adjustment screw 11 is used. This is to make the strength suitable for forming the screw hole 10. For example, as a method of integrating the metal plate and the resin plate of the hinge member 5, although not shown in the drawing, both of the above are used. Appropriate methods such as bonding or molding inside the resin plate and integral forming are effective.
[0035]
Further, in the illustrated case, the hinge member 5 has a bent portion 7a that bends inward (that is, the door opening / closing end side) toward the proximal end in the vicinity of the notch hole 4a of the door mounting member, and a distal end side thereof. Although it has a shape having a hook-like portion bent in a hook shape toward the outside, it may be a straight shape not provided with a bent portion or a hook-like portion.
[0036]
If the metal plate 7 of the hinge member 5 is made of an elastic material such as steel or spring steel, it is easy to adjust the warp angle of the tip 7a with the adjusting screw 11, and even if over-adjusted, the screw is loosened. The warp can be returned by the elasticity of the resin plate and the metal plate.
[0037]
When a synthetic resin material having sufficient strength, toughness, and durability is used for the resin plate 6 of the hinge member 5, although not shown in the drawing, the metal plate is placed on the proximal end side and the distal end side at the bent portion 7a. A structure in which the structure is divided into two and the angle of the warp of the tip is adjusted only by the elasticity of the resin plate 6 may be adopted.
[0038]
The resin plate 6 may be made of a material rich in mechanical strength and elasticity, but has excellent fatigue resistance, toughness, wear resistance, and is self-lubricating so that the pin support portion can be smoothly rotated even without oiling. It is preferable to use an excellent material.
A commonly known synthetic resin having these properties is known as POM (polyacetal), and this synthetic resin material may be used, but is not limited thereto.
[0039]
On the other hand, the hinge member is not formed of a composite material such as a resin plate and a metal plate as in the above embodiment, but is not illustrated, but only a thin metal plate, only a synthetic resin plate, or other appropriate material is used as a single material. In addition, a plurality of appropriate materials may be integrally stacked.
[0040]
When the hinge member is formed of only a thin metal plate or a resin plate, if necessary, a metal nut is attached to the position of the screw hole of the adjustment screw 11 or the mounting screw 13 by an appropriate means such as welding, molding, or press fitting. The strength of the hole can be increased.
[0041]
The screw hole of the adjusting screw 11 is not shown in the figure, but a hinge member whose outer shape is a spherical or cylindrical member that is formed by penetrating the screw hole can be changed to the left and right like a known universal joint. It is convenient that the hinge member can be more easily deformed when mounted on.
[0042]
【The invention's effect】
The hinge mechanism of the open / close door of the present invention can adjust the position and inclination of the door only by adjusting the screwing amount of the adjusting screw after the door is attached to the box. The work process of attaching the adjustment member to the hinge and attaching the door again becomes unnecessary, and not only can the position of the door be adjusted very easily and in a short time, but also the installation of the door due to the installation conditions and long-term use Even if it goes crazy, it can be easily corrected by the same work. Further, in the hinge mechanism of the opening / closing door of the present invention, it is not necessary to prepare a large number of adjustment members having different thicknesses as in the prior art, and there is no need for extra costs for the production and management of the adjustment members. The adjustment work time can be shortened and the cost can be greatly reduced.
