Description

  The present invention relates to a door unit with a hinge (particularly a hinge for a hinged door), and a method for mounting the door unit.

  For example, when installing a door such as a door for entering and exiting a room to a door mounting part such as a fixed frame, the mutual distance (gap) between the door and the fixed frame is within a predetermined range so that the door can be opened and closed smoothly. It is necessary to adjust to. Further, even when the door or the fixed frame is deformed or the mounting position of the door is shifted due to use, it is necessary to readjust the mutual distance between the door and the fixed frame. And in order to perform these adjustments properly, the door thickness direction (front and back of the worker facing the door front), the door width direction (same left and right) and the door height direction (also top and bottom) three directions A hinge that enables position adjustment (gap adjustment) at has been disclosed (see Patent Document 1).

Japanese Patent Laid-Open No. 10-82234

  According to such a hinge, the mutual distance (gap) between the door and the fixed frame can be adjusted within an appropriate range by adjusting the position of the door in the front-rear, left-right, and vertical directions. However, in the hinge of Patent Document 1, since the width direction (left and right) adjustment of the door is performed by turning around the axis of the hinge shaft, the front and rear direction shift occurs due to the width direction adjustment, and the front and rear direction readjustment is performed. May be required. For this reason, in order to efficiently adjust the gap, it is necessary to determine an adjustment procedure in advance so that the position adjustment in the front-rear direction is performed after the position adjustment in the width direction of the door. Further, when the door unit provided with the hinges that can be adjusted in three directions at the top and bottom of the door is attached to the door mounting portion, for example, if the hinge shaft of the upper hinge protrudes upward, There is a possibility that the upper end contacts the ceiling wall and damages the ceiling wall.

  The object of the present invention is to easily adjust the door position in three directions orthogonal to each other like the thickness direction, width direction and height direction of a door body such as a hinged door, and to the door mounting portion via a hinge shaft. It is providing the door unit with a hinge which has the safety | security at the time of attachment, and the attachment method of the door unit.

A locking portion is formed to prevent or suppress the protrusion amount from protruding from the upper surface of the attachment portion side hinge plate.

Moreover, in order to solve the said subject, the door unit with a hinge of this invention is the following.
In the hinged door unit in which the lower hinge is attached to the lower part of the door body such as a hinged door that can be opened and closed with respect to the door mounting part such as the fixed frame, and the upper hinge is attached to the upper part of the door body,
The lower hinge and the upper hinge are each an attachment-side hinge plate as an attachment-side hinge attached to a door attachment such as a fixed frame, and a door body such as a hinged door that can be opened and closed with respect to the door attachment. A hinge having a door-side hinge plate as a door-side hinge portion and a hinge shaft that couples both the hinge plates so as to be relatively rotatable in the opening / closing direction of the door body,
Of these, the lower hinge is
The door body is attached to the door-side hinge plate, and the door body is moved in the thickness direction as the first direction on a surface perpendicular to the axis of the hinge shaft in a state where the door body closes the door attachment portion, and The movement of the door body in the width direction of the door body as a second direction orthogonal to the thickness direction on the orthogonal plane and the height direction of the door body as a third direction along the axis of the hinge shaft.

Furthermore, the upper end of the shaft-shaped member is at least one of the shaft-shaped member constituting the hinge shaft and the attachment-side hinge plate engaged with the shaft-shaped member via the resilient member. A locking portion is formed to prevent or suppress the protrusion amount from protruding from the upper surface of the attachment portion side hinge plate.

  According to such a hinged door unit, the position adjustment of the door body (for example, the hinged door) in three directions orthogonal to each other (for example, the thickness direction, the width direction, and the height direction) can be independently performed and the door mounted. It is possible to carry out all at once on the inside or outside of the door body with the part (for example, a fixed frame) closed. That is, the operator does not have to change the work position between the inside and the outside of the door body (room entrance) by opening and closing the door body in the middle of the position adjustment work of the door body. Further, since the position adjustment in the three directions of the door body can be performed independently, there is no need to readjust the deviation in the thickness direction caused by the position adjustment in the width direction, for example. ) Need not be determined in advance. Therefore, the mutual interval (gap) between the door body and the door mounting portion can be adjusted efficiently in a short time. Thus, “to independently adjust the position of the three directions of the door body” means that “the position adjustment in any one direction does not cause a shift in the other direction” and “the position in the three directions. Both meanings of "regardless of order of adjustment" are included. Furthermore, since the position adjustment in these three directions of the door body is performed in a state where the door body closes the door mounting portion, the door body and the door mounting portion are properly viewed while actually confirming the mutual distance (gap). It is possible to efficiently find and adjust the gap.

  And the hinge provided with the 3rd adjustment mechanism is used as a lower hinge, Therefore The position adjustment of 3 directions orthogonal to each other can be performed with an easy attitude | position. Further, by using a hinge having a follow-up movement mechanism instead of the third adjustment mechanism as the upper hinge, the cost of the upper hinge, and thus the cost of the entire door unit can be reduced.

  Further, at least one of the shaft-like member constituting the hinge shaft of the upper hinge and the attachment-side hinge plate engaged with the shaft-like member, the upper end of the shaft-like member is the upper surface of the attachment-side hinge plate A locking portion is formed for preventing the protrusion from the protrusion or suppressing the protrusion amount. As a result, the hinge shaft of the upper hinge does not protrude significantly above the hinge plate on the mounting part side, so when the door unit is attached to the door mounting part, the upper end of the hinge shaft contacts the ceiling wall and the ceiling wall or hinge shaft Safety can be ensured without damage.

  Such a hinged door unit has an upper hinge and a lower hinge hinge shaft (specifically, in a state where the shaft member of the upper hinge protrudes and maintains downward against the elastic force of the elastic member. The hinge shafts of the upper hinge and the lower hinge can be attached to the door-side hinge plate of the door attachment portion (in a form that penetrates the overlapped portion of the first engagement portion and the second engagement portion). Therefore, the attachment work of the hinged door unit to the door attachment portion can be performed easily and safely.

  Further, the shaft-like member and / or the attachment-part-side hinge plate is configured to protrude and maintain the shaft-like member downward against the elastic force of the elastic member during the attachment work to the door attachment portion. It is desirable to arrange a temporary fixing member. After attaching the door unit to the door mounting part via the hinge shaft, the temporary fixing member is removed from the shaft-shaped member and the mounting part side hinge plate. And can be carried out efficiently in a short time. As the temporary fixing member, a synthetic resin-made annular clip (retaining ring), a paper-made cylindrical stopper, a metal-made axial or cylindrical penetrating member, or the like can be used.

  In addition, the locking portion is a polymer material receiving member that receives the upper end of the shaft-shaped member by closing a through-hole formed in the mounting portion-side hinge plate so that the shaft-shaped member can penetrate. Can be configured. By blocking the through hole of the attachment-side hinge plate with a receiving member made of a polymer material, direct contact between the shaft-like member and the attachment-side hinge plate is avoided, and wear of these parts, which are usually made of metal, is avoided. And noise can be prevented. The polymer material includes plastic (synthetic resin) and elastomer (synthetic rubber).

  At that time, the receiving member has a recess into which the tip of the shaft-shaped member can be inserted, and is covered with a cap shape (cylindrical shape) inside the through hole, and a small hole for venting air is formed on the top wall portion forming the recess. When it has, the front-end | tip of a shaft-shaped member can be received reliably by the inner surface (lower surface) of a top wall part. When the shaft-shaped member is inserted into the receiving member, the air in the receiving member (recessed portion) compressed by the piston action is discharged from the small hole formed in the top wall portion. Will not be removed from the receiving member due to insufficient insertion.

  More specifically, the receiving member has a recess into which the tip of the shaft-like member can be inserted, while the shaft-like member is formed with a mark for indicating or reading the insertion depth of the receiving member into the recess. May be. If the shaft-shaped member is inserted into the recess of the receiving member with this mark as a clue during the mounting operation of the door unit to the door mounting portion, the shaft-shaped member will not come off the receiving member due to insufficient insertion. In addition, as such a mark, a stepped shaft or a tapered shaft can be used for the shaft-shaped member, or a groove, a mark, a scale, or the like can be formed on the whole or a part of the outer peripheral surface of the shaft-shaped member.

Next, in order to solve the above problems, the present invention is a method of attaching a hinged door unit to a door attachment portion such as a fixed frame,
With the shaft member of the upper hinge protruding and maintained downward against the elastic force of the resilient member, via the hinge shafts of the upper and lower hinges (specifically, the upper and lower hinges) The hinge shaft of the hinge is attached to the door-side hinge plate of the door attachment portion (in a form in which the hinge shaft penetrates the overlapped portion of the first engagement portion and the second engagement portion).

  In this way, by attaching the hinged door unit to the door mounting portion with the shaft member of the upper hinge protruding and maintained downward against the elastic force of the elastic member, as described above, the hinge The attachment work of the door unit can be facilitated, and the attachment work can be performed efficiently and safely in a short time.

Thereby, based on opening / closing of the hinged door 2 with respect to the fixed frame 5, the door side hinge plate 7 and the sleeve 42 rotate integrally with the front / rear slider 11 and the left / right slider 21 around the axis O <b> 3 of the hinge shaft 8.

  The frame-side holding shaft 41 and the sleeve 42 are arranged in such a manner as to penetrate through overlapping portions of the front and rear sliders 11 and the left and right sliders 21, that is, through holes 11a and 21a. In addition, since the configurations of the front / rear adjustment mechanism 10, the left / right adjustment mechanism 20, and the storage case 50 are the same as those of the lower hinge 3, description thereof is omitted.

  As shown in FIG. 6, a plastic receiving member 106c (locking portion) is fitted into the frame-side hinge plate 106 so as to close the through hole 106a in the height direction O3. The receiving member 106 c prevents (contacts) the upper end of the frame-side holding shaft 41 so as not to protrude greatly from the upper surface of the frame-side hinge plate 106.

  Specifically, the receiving member 106 c is formed in a cap shape so as to open downward, and has a recess 106 e into which the tip (upper end) of the frame-side holding shaft 41 can be inserted. Further, a locking flange 106f is integrally formed at the opening peripheral edge of the receiving member 106c on the lower end side, and an insertion portion formed on the outer peripheral edge on the upper end side is slightly larger in diameter than the inner diameter of the through hole 106a. 106 g is integrally formed. The insertion portion 106g is elastically deformed and reduced in diameter when inserted into the through hole 106a, and is elastically restored to the diameter before deformation after the insertion, thereby preventing the through hole 106a from coming off. In addition, a small hole 106h for venting air is formed in the top wall portion constituting the bottom of the recess 106e of the receiving member 106c.

  As shown in FIG. 6, in this embodiment, the bottom surface of the recess 106 e of the receiving member 106 c is positioned slightly above the top surface of the frame side hinge plate 106. As a result, the upper end of the frame-side holding shaft 41 is protected by the plastic receiving member 106c, and the follow-up stroke of the frame-side holding shaft 41 can be increased, so that the mounting operation can be performed easily. In addition, when attaching so that the recessed part 106e of the receiving member 106c may not protrude upwards rather than the frame side hinge plate 106, it becomes difficult for the frame side holding shaft 41 etc. to contact a ceiling wall.

  As shown in FIG. 7, the large-diameter portion 41a of the frame-side holding shaft 41 indicates how deeply the upper end (tip) of the large-diameter portion 41a is inserted into the recess 106e of the receiving member 106c (or A mark 41e is formed for easy reading. The mark 41e shown in FIG. 7 includes a stepped portion that is intermittently reduced in diameter or an inclined portion that is continuously reduced in diameter (for example, in a tapered shape) above the large-diameter portion 41a.

  The frame side holding shaft 41 has a female screw portion 41c formed on the end surface (lower end surface) of the main body portion 41b opposite to the side on which the large diameter portion 41a is formed. The knob 45 (operation tool) is fixed to the frame-side holding shaft 41 by the fixing screw 44 (mounting tool) being screwed with the female screw portion 41 c. Therefore, normally, the hinged door 2 is held on the frame side hinge plate 106 side (upper side) by the elastic force of the compression coil spring 43. When the knob 45 is pulled downward against the elastic force of the compression coil spring 43 and the large-diameter portion 41a of the frame-side holding shaft 41 is extracted from the recess 106e of the receiving member 106d of the frame-side hinge plate 106, the hinged door 2 can be removed from the fixed frame 5.

  Further, as shown in FIG. 9B, the frame side holding shaft 41 is made to resist the elastic force of the compression coil spring 43 when the frame side holding shaft 41 is attached to the door unit 1 fixed frame 5. In order to protrude and maintain downward, the temporary fixing member 9 is interposed between the top wall portion 50a of the storage case 50 and the knob 45. A fitting notch portion 9a for fitting the frame side holding shaft 41 is formed on the distal end side of the temporary fixing member 9, and a ring is formed on the proximal end side which is integrally formed continuously with the fitting notch portion 9a. A shaped grip 9b is formed.

  Then, in the state where the knob 45 is pulled downward, the fitting notch 9a of the temporary fixing member 9 is pushed in so as to be fitted to the frame side holding shaft 41, thereby mounting the upper end (tip) of the frame side holding shaft 41. ) Is immersed in the storage case 50, and the frame side holding shaft 41 can be protruded and maintained downward.

A method of assembling the upper hinge 4 having the above configuration will be described.
(1) Storage case 50 assembly process Since it is the same as the storage case 50 assembly process of the lower hinge 3, description is abbreviate | omitted.

(2) Storage Case 50 Setting Step The storage case 50 is placed and fixed on the support piece 7b of the door side hinge plate 7. The main body portion 42b of the sleeve 42 is inserted into the through hole 7d of the support piece 7b along the height direction O3, and the flange portion 42c is seated on the door side hinge plate 7 on the upper surface of the support piece 7b. The handle 45 is fixed to the main body 41b of the frame-side holding shaft 41 protruding from the storage case 50 with a square hole washer 53 and a washer 54 positioned on the top surface of the top wall 50a. To do. As a result, the frame-side holding shaft 41 and the sleeve 42 can be rotated together with the door-side hinge plate 7 (the hinged door 2), and the frame-side holding shaft 41 is in the height direction with respect to the storage case 50 and the sleeve 42. It can move along O3.

Next, a method for attaching the door unit 1 to the fixed frame 5 will be described.
(1) Preparatory process In the lower hinge 3, while fixing one frame side hinge plate 6 to the fixed frame 5, the other door side hinge plate 7 is fixed to the lip 2b below the hinged door 2 (see FIG. 1). . Similarly, in the upper hinge 4, one frame side hinge plate 106 is fixed to the fixed frame 5, and the other door side hinge plate 7 is fixed to the top 2a of the hinged door 2 (see FIG. 1). In the state where the knob 45 of the upper hinge 4 is pulled downward, the fitting notch 9a of the temporary fixing member 9 is pushed in and attached so as to be fitted to the frame side holding shaft 41.

(2) Attaching step Then, the frame-side fixed shaft 31 fixed to the frame-side hinge plate 6 of the lower hinge 3 is inserted into the sleeve 32 held by the door-side hinge plate 7, and the tip of the frame-side fixed shaft 31 is inserted. 31a and the contact surface 33c of the pivot bearing 33 are brought into contact with each other, and the lower hinge 3 is held by the frame side hinge plate 6. Subsequently, the upper hinge 4 in a state in which the upper end (tip) of the frame side holding shaft 41 is immersed in the storage case 50 by the temporary fixing member 9 and the frame side holding shaft 41 protrudes downward is attached to the frame side holding shaft 41. It moves so that the center positions of the large diameter portion 41a and the locking portion 106c of the frame side hinge plate 106 are aligned. At this time, the upper end (tip) of the frame side holding shaft 41 can move without contacting the fixed frame 5. After that, by removing the temporary fixing member 9 from the frame side holding shaft 41, the frame side holding shaft 41 is inserted into the recess 106e of the locking portion 106a of the frame side hinge plate 106 by the elastic force of the compression coil spring 43, The upper hinge 4 is held by the door side hinge plate 7. As a result, the door unit 1 is attached to the fixed frame 5 and can be opened and closed.

Next, a method for adjusting the position of the door unit 1 with respect to the fixed frame 5 (a method for adjusting the gap) will be described with reference to FIGS. 1, 2, and 4.
(1) Thickness direction O1 adjustment process (front-rear gap S1 adjustment process)
The hinged door 2 is maintained in a state of closing the fixed frame 5. The hinged door 2 is moved in the thickness direction O1 by the front / rear adjustment mechanism 10 provided on the lower hinge 3 and the upper hinge 4 to adjust the position. Thereby, the front-rear gap S1 (see FIG. 1B) between the hinged door 2 and the fixed frame 5 is adjusted.

(2) Width direction O2 adjustment process (left-right clearance S2 adjustment process)
The left and right adjustment mechanisms 20 provided on the lower hinge 3 and the upper hinge 4 respectively move the hinged door 2 in the width direction O2 to adjust the position. Thereby, the left-right clearance S2 (see FIG. 1A) between the hinged door 2 and the fixed frame 5 is adjusted.

(3) Height direction O3 adjustment process (upper and lower gap S3 adjustment process)
By the vertical adjustment mechanism 30 provided in the lower hinge 3, the hinged door 2 is moved in the height direction O3 to adjust the position. At this time, the vertical movement mechanism 40 provided on the upper hinge 4 follows the movement of the hinged door 2 in the height direction O3. Thereby, the vertical gap S3 (see FIG. 1A) between the hinged door 2 and the fixed frame 5 is adjusted.

  In this way, the operator can perform the above three adjustment steps independently and collectively in the inside of the hinged door 2 regardless of the order. Accordingly, the mutual distance between the hinged door 2 and the fixed frame 5 can be finely adjusted efficiently in a short time while directly viewing the gaps S1, S2, S3. Of course, since the above three steps can be carried out simultaneously, in this case, the work efficiency can be further improved.

  At that time, since the adjusting screws 12, 22, 33a are concentrated at the left side wall 50b and the top wall 50a of the storage case 50, the position adjustment (gap adjustment) of the hinged door 2 can be performed more efficiently. The

  FIG. 10 shows a modification of the frame side holding shaft 41. In FIG. 10A, a groove-shaped mark 41e is formed at a position where the step portion of the frame side holding shaft 41 is formed. Further, in FIG. 10B, a linear mark is affixed, or a scale or the like is formed on the whole or a part in the circumferential direction to form the mark 41e. The mark 41e may be formed at a position where the upper end (tip) of the frame-side holding shaft 41 is located in the recess 106e and hidden from the outside when the frame-side holding shaft 41 is inserted into the recess 106e. Thereby, it can confirm reliably that the large diameter part 41a of the frame side holding | maintenance shaft 41 is inserted in the recessed part 106e of the receiving member 106c only by the presence or absence of the mark 41e at the time of visual observation (refer FIG. 6).

  FIG. 11 shows a modification of the temporary fixing member 9. In FIG. 11A, a through hole 9 c is formed in the frame side holding shaft 41, and a shaft-like pin 9 d is inserted into the through hole 9 c to constitute the temporary fixing member 9. 11 (b) forms a temporary fixing member 9 by forming a slit 9f in a cylindrical body 9e and winding it around the frame side holding shaft 41 via the slit 9f. As a result, the upper end (tip) of the frame side holding shaft 41 is immersed in the storage case 50, and the frame side holding shaft 41 protrudes downward. The temporary fixing member 9 can be formed of a material such as synthetic resin, paper, or metal.

  In the above embodiment, only the case where the axis O3 of the hinge shaft 8 is positioned in the vertical direction (vertical direction) has been described. However, the present invention relates to a hinge or door unit in which the axis O3 is disposed in another direction (for example, the horizontal direction). Also applies. Further, the position adjustment (gap adjustment) of the hinged door 2 in the three directions may be performed from the outside of the hinged door 2 (room entrance) while the hinged door 2 closes the fixed frame 5. Further, hinges 3 and 4 may be provided on the left side of the hinged door 2.

  By the way, as shown in FIGS. 3 and 5, the shape of the through hole 7d of the door side hinge plate 7, the outer shape of the remaining portion 32b2 of the sleeve 32, and the outer shape of the remaining portion 42b2 of the sleeve 42 are all (pseudo). Although formed in a quadrangular shape, these may be other (pseudo) polygonal shapes, (pseudo) elliptical shapes, or the like. That is, these shapes allow the sleeves 32 and 42 to move relative to the sliders 11 and 21 (through holes 11a and 21a) in the width direction O2 and the thickness direction O1, respectively, when the position of the hinged door 2 is adjusted, and It is sufficient that the sleeves 32 and 42 can be rotated integrally with the sliders 11 and 21 (through holes 11a and 21a) when the hinged door 2 is opened and closed.
