[Problems to be solved by the invention]
FIG. 5 shows an attachment mechanism 110 that attaches the door 102 to the box body 101 of the storage 100 so that the door 102 can be opened and closed. The attachment mechanism 110 includes a bracket 112 attached to the main body 101, and a hinge pin 111 attached to the bracket 112 and rotatably supporting the door 102. The hinge pin 111 includes a shaft portion 113 protruding so as to be the center of rotation of the door 102, and a fixing bolt portion 115 protruding to the opposite side across the shaft portion 113 and the flange portion 114. On the other hand, the bracket 112 includes a fixing portion 119 fixed to the main body 101 and a support portion 118 protruding from the fixing portion 119 to the door side and to which the hinge pin 111 can be attached. The fixing portion 119 is formed with a mounting hole 121 used for fixing the bracket 112 to the main body 101 with a bolt 129 and a nut 128. The mounting hole 121 is used to move the fixing position of the bracket 112 in the width direction X of the door. It is a long hole or groove that is long in the X direction so that it can be adjusted. The support portion 118 is provided with a support hole 122 for inserting the bolt portion 115 of the hinge pin 111 and fixing the hinge pin 111. The support hole 122 is provided so that the position of the door 102 in the front-rear direction Y can be adjusted. The holes or grooves are long in the Y direction.
[0005]
Therefore, when adjusting the position of the door 102 with respect to the main body 101, the bracket 112 is moved in the width direction X using the elongated hole 121 in the width direction, and the position of the hinge pin 111 is adjusted in the front-rear direction using the elongated hole 122. This is done by moving in the direction Y. However, in many cases, in order to move the door 102 without rattling and to seal the main body 101, it is necessary to simultaneously adjust the width direction X and the front-back direction Y, and the position of the bracket 112 and the hinge pin 111 The position and the position must be adjusted at the same time, and the support of the door 102 becomes unstable during work, resulting in poor workability. Also, skill is required to adjust the position of the bracket 112 and the position of the hinge pin 111 at the same time.
[0006]
JP-A-6-288141 discloses that a first circular hole is formed in a base plate, the first circular plate is rotatably fitted in the first circular hole, and the first circular plate is eccentric. It is described that a second disk is fitted into a second circular hole, and an eccentric rotation support shaft is protruded from the second disk. By moving the two eccentric members, that is, the first disk and the second disk, the position of the rotation spindle can be finely adjusted in two directions, and the position of the door can be adjusted without moving the base plate. Can be finely adjusted in two directions. However, for this purpose, it is necessary to move the two parts at the same time, and the position or rotation angle of one member is influenced by the position or rotation angle of the other member. Therefore, the position of the door is finely adjusted in two directions. This is a very troublesome operation, and this method also has considerable skill, and the range of fine adjustment cannot be said to be wide.
[0007]
Therefore, an object of the present invention is to provide an attachment mechanism that can easily and stably adjust the position of a door with respect to a main body.
[0008]
[Means for Solving the Problems]
For this reason, in the present invention, a hinge pin having an axis (second axis) eccentric with respect to an axis (first axis) serving as a center of rotation, and a long hole or groove into which the second axis is inserted are provided. Provided is an attachment mechanism in combination with a provided bracket. That is, the mounting mechanism of the present invention is a mounting mechanism for opening and closing the door with respect to the main body, and has a bracket mounted on the main body, and a hinge pin that can be inserted into a groove provided in the bracket, The hinge pin includes a flange portion that prevents the groove from coming off, a first shaft protruding from the flange portion so as to be the center of rotation of the door, and a second shaft protruding from the flange portion so as to be inserted into the groove. Provided, the second axis being eccentric with respect to the first axis. The bracket can also be mounted on a door, in which case the first axis is connected to the body and is the center of rotation of the bracket.
[0009]
With the mounting mechanism of the present invention, for example, when the bracket is mounted on the main body, the position of the pivot center of the door can be adjusted by moving the first axis in the direction of the groove by moving the hinge pin along the groove of the bracket. . In addition, since the first axis moves eccentrically with respect to the second axis by rotating the hinge pin, the first axis is moved in a direction perpendicular to the direction in which the groove of the bracket extends, and the center of rotation of the door is rotated. The position can be adjusted. Therefore, the position of the door relative to the main body can be two-dimensionally adjusted only by adjusting the position and angle of the hinge pin with the bracket attached to the main body. The same applies when the bracket is attached to the door.
[0010]
Therefore, when the bracket is attached to the main body, the position of the door can be stably adjusted while the door is supported by the main body via the bracket. In addition, by using a bolt as the second shaft, if the nut is fastened to the bolt and the bracket is sandwiched between the flanges, the position and rotation angle of the hinge pin with respect to the bracket can be easily determined. Therefore, when the bolt is loosened, the position of the door can be finely adjusted while the door is supported by the main body via the bracket, and when the door is adjusted to an appropriate position, just tighten the bolt to set the pivot position of the door at that position. Can be fixed. For this reason, if the mounting mechanism of the present invention is adopted, the position adjustment between the door and the main body becomes a very simple operation, and it is not necessary to work in an unstable state of the door. The technology used is no longer necessary.
[0011]
Therefore, it is a storage having an attachment mechanism for opening and closing the door with respect to the main body, the attachment mechanism includes a bracket attached to the main body or the door, and a hinge pin that can be inserted into a groove provided in the bracket. The hinge pin is provided with a flange portion for retaining the groove, a first shaft protruding from the flange portion so as to be a center of rotation of the door or the main body, and a second shaft protruding from the flange portion so as to be inserted into the groove. In the storage where the second shaft is eccentric with respect to the first shaft, the positional relationship between the door and the main body can be easily finely adjusted, and the door can be opened and closed without play. Furthermore, when the door is closed, the door can be provided in close contact with the main body, and a sufficient heat insulating performance can be obtained.
[0012]
Whether the second shaft is at the center of the flange or the first shaft is at the center of the flange, the operation and effects of the present invention described above are not changed. However, the relationship between the first shaft and the flange portion appears on the side of the door and is a part that can be seen by the user. Therefore, the first shaft is located at the center of the flange portion, and the second shaft is eccentric from the center of the flange portion. Can be provided.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in more detail with reference to the drawings. FIG. 1 shows the appearance of a storage having a mounting mechanism according to the present invention. The storage 1 has a heat-insulating box main body 3 having an opening 2 on the front surface, and two doors 5 and 6 for opening and closing the opening 2. The main body 3 is pivotally attached to the main body 3 by an attachment mechanism 10 that connects the main body 6 to the main body 3. Therefore, by opening one or both of the doors 5 and 6 to open the opening 2, it is possible to carry in and out a stock such as rice and wine.
[0014]
The mounting mechanisms 10 are provided at two locations above and below the one door 5 or 6, and each of the mounting mechanisms 10 is provided in the front-rear direction Y and the left-right direction (width direction) ) A function for adjusting the position of X is provided. Therefore, the doors 5 and 6 are at positions where the doors 5 and 6 can be opened and closed smoothly without rattling with respect to the box main body 3, and further, when closed, close the opening 2 so that sufficient heat insulating performance can be obtained. Further, an environmental control unit 7 including any or all of a cooling device, a heating device, and a humidifying device is attached to an upper portion of the box main body 3. Environment can be maintained at desired conditions.
[0015]
FIG. 2 shows one of the mounting mechanisms 10 in an enlarged manner. Since the mounting mechanisms 10 of this example are all the same in configuration, the mounting mechanism 10 mounted on the door 6 will be described as a representative. FIG. 2A is a plan view of the mounting mechanism 10, and FIG. 2B is a cross-sectional view of the mounting mechanism 10. The mounting mechanism 10 includes a bracket 11 mounted on the upper surface 3a of the box body 3, and a hinge pin 20 that can be inserted into a groove or a long hole 13 provided in the bracket 11, and a combination of the bracket 11 and the hinge pin 20. Thereby, the position of the door 6 in the front-rear direction Y and the width direction X with respect to the box body 3 can be adjusted.
[0016]
The bracket 11 is a flat member extending from the upper surface 3 a of the box body 3 to the door 6, and includes a fixing portion 19 attached to the box body 3 and a support portion 18 extending from the fixing portion 19 and supporting the door 6. ing. The fixing portion 19 is provided with four screw holes 14 for fixing the bracket 11 on the upper surface 3 a of the box main body 3, and the bracket 11 can be fixed to the main body 3 by bolts 129 and nuts 128. The support portion 18 is provided with a rectangular elongated hole or groove 13 extending long in the front-rear direction Y of the door 6.
[0017]
FIGS. 3A and 3B show the configuration of the hinge pin 20 in a front view and a plan view. The hinge pin 20 of the present example includes a disk-shaped flange portion 25 for preventing the bracket 11 from coming off the groove 13, and two shafts 21 and 22 protruding downward and upward from the flange portion 25. A shaft (first shaft) 21 protruding downward, that is, on the side of the door 6, becomes a center of rotation when the door 6 is opened and closed by being inserted into the upper surface 6a of the door 6. A shaft (second shaft) 22 protruding on the opposite side to the first shaft 21 fixes the position of the hinge pin 20 by being inserted into the groove 13 of the bracket 11, and the position of the pivot center of the door 6 with respect to the main body 3, that is, Then, the position of the door 6 with respect to the main body 3 is fixed. These axes 21 and 22 are mutually eccentric, as indicated by centerlines A and B. In the hinge pin 20 of the present example, the first shaft 21 is arranged at the center of the flange 25, and the second shaft 22 is arranged at a position eccentric to the outside from the center of the flange 25.
[0018]
The second shaft 22 is a bolt having a thread formed on the outer periphery. The second shaft 22 is passed through the groove 13 of the bracket 11, and the nut 29 is tightened from the side opposite to the flange 25, so that a desired position of the groove 13 is obtained. In addition, the hinge pin 20 can be fixed at a desired angle. The second shaft 22 is provided with a hexagonal hole 28 at the tip end surface thereof so that the position of the second shaft 22 in the front-rear direction Y and the angle of the hinge pin 20 do not move during the work of tightening the nut 29. By inserting a tool into the hexagonal hole 28, the position and angle of the hinge pin 20 can be maintained.
[0019]
FIG. 4 shows how the position of the door 6 with respect to the box body 3 is adjusted, with the bolt 129, the nut 128, and the nut 29 omitted. FIG. 4A illustrates a state when the hinge pin 20 is rotated, and FIG. 4B illustrates a state when the position of the hinge pin 20 is moved in the front-rear direction Y. As shown in FIG. 4A, when the hinge pin 20 is rotated, the second shaft 22 is eccentric with respect to the first shaft 21 which is the center of rotation of the door 6, and the second shaft 22 is The pivot center of the door 6 can be moved in a direction orthogonal to the groove 13 of the bracket 11, that is, in the present embodiment, in the width direction X of the door 6.
[0020]
On the other hand, as shown in FIG. 4B, the position of the second shaft 22 of the hinge pin 20 can slide in the front-rear direction Y along the groove 13. Therefore, the position of the door 6 can be moved in the front-rear direction Y with respect to the box body 3. For this reason, the nut 29 is loosened so that the hinge pin 20 moves with respect to the bracket 11 while the bracket 11 is fixed to the box body 3 with respect to the position of the door 6 in the front-rear direction Y and the width direction X with respect to the box body 3. Just can be adjusted. Therefore, the door 6 can be moved in the front-rear Y direction and the left-right X direction for fine adjustment. However, the door 6 is basically still supported by the main body 3 by the bracket 11, and the position is adjusted. The door 6 does not rattle up and down, and the bracket 11 does not tilt and the hinge pin 20 comes off, so that the door 6 does not come off the main body 3. For this reason, by using the mounting mechanism 10 of the present example, the door 6 is supported in a state where the door 6 can smoothly turn with respect to the main body 3 even while the position of the door 6 is being adjusted, and the position of the door 6 can be safely changed. Can be fine-tuned. Further, since the position can be finely adjusted while turning the door 6, the position of the door 6 can be easily and accurately adjusted.
[0021]
When the position of the door 6 is moved with respect to the main body 3, the hinge pin 20 moves in the groove 13 of the bracket 11 in the front-rear direction Y, and the hinge pin 20 rotates accordingly. That is, if the position adjustment of the door 6 is simply in the front-rear direction Y, the hinge pin 20 only slides in the groove 13, but when the movement in the width direction X is included, the hinge pin 20 moves the second shaft 22. It rotates to the center and slides the groove 13. However, such movement of the hinge pin 20 is automatically performed by rotating and / or sliding the hinge pin 20 with respect to the bracket 11 in conjunction with or following the movement of the door 6 when adjusting the position of the door 6. It is performed, and there is no need to be aware of the moving distance of the groove 13 of the hinge pin 20 or the rotation angle of the hinge pin 20. Then, when the position of the door 6 is in a desired state with respect to the main body 3, the position of the door 6 can be fixed by tightening the nut 29 at the position and angle of the hinge pin 20 at that time. Therefore, in the mounting mechanism 10 of the present embodiment, the position adjustment of each mounting mechanism 10 only needs to operate the nut 29 that fixes the hinge pin 20 to the bracket 11, and no effort is required. As described above, the mounting mechanism 10 of the present embodiment is performed by a simple process (operation) in which the nut 29 is loosened, the position with respect to the main body 3 is adjusted by holding the door 6, and the nut 29 is tightened when a desired state is obtained. The work of adjusting the position of the door 6 is extremely easy, and no skilled technique is required.
[0022]
Although the position adjustment of the door 6 has been described, the position of the door 5 can be adjusted by the same operation. Further, in this example, the mounting mechanism in which the bracket 11 is fixed to the side of the main body is described. However, the bracket may be fixed to the door and rotatably mounted to the main body with a hinge pin. Further, in the hinge pin 20, the second shaft 22 for attaching the hinge pin 20 to the bracket 11 is arranged at the center of the flange 25, and the first shaft 21 may be positioned eccentrically with respect to the center of the flange 25. It is possible to secure the area of the flange portion 25 facing the nut 29 when sandwiching the nut 29 and the flange portion 25 with the bracket 11, which is a preferable arrangement for reducing the size of the flange portion 25. However, the first shaft 21 protrudes toward the door side and is a member that is easily visible to the user. A design in which the first shaft 21 is not at the center of the flange portion 25 tends to give an unstable feeling, and the component is defective. It may be seen as. In addition, since the door 6 turns around the first shaft 21, it is easy to ensure a uniform contact area with the door 6. Therefore, in the present example, the first shaft 21 is arranged at the center of the flange portion 25 so that the flange portion 25 has a size enough to secure an area facing the nut 29.
[0023]
Further, in the above, the present invention has been described by taking the storage as an example, but the present invention is not limited to the storage, and various types of mounting mechanisms for attaching the door or the door to the main body so as to be openable and closable, for example, the entrance of a house, etc. Applicable to location mounting mechanism.
[0024]
【The invention's effect】
As described above, in the present invention, the bracket for connecting the main body and the door is provided with a groove, and the hinge pin inserted into the groove and pivotally supporting the door is provided with two eccentric shafts. With this mounting mechanism, the hinge pin rotates and moves along the groove, so that the position of the main body and the door can be adjusted in each direction only by the movement of the hinge pin. Therefore, the position can be adjusted only by loosening the fixation of the hinge pin to the bracket and moving the door, and the operation of adjusting the position of the main body and the door can be performed very easily and safely.
