Description

[Detailed description of the device]

[0001]

[Industrial applications]

 In this invention, after the door frame and the vane are individually attached to the door, the door can be lifted and suspended, or after the door is rotatably attached to the door frame, the axial cylinder portion on the door side is attached. The present invention relates to a so-called slip-on type hinge that can be pulled out from the shaft pin to remove the door.

[0002]

[Prior art]

 In this type of hinge, conventionally, a door frame and a pair of blade plates fixed to the door, a shaft cylinder portion integrally formed on the blade plate by means of a curling process, and the like can be inserted into and removed from both shaft cylinder portions. A structure having a shaft pin to be inserted is known.

Generally, a plurality of hinges are attached at intervals in the up-down direction of the door, and it is a usage pattern in which a shaft pin is held in a shaft cylinder portion on the door frame side, but the door is lifted and suspended. In this case, it is difficult to fit a plurality of shaft pins that are located on substantially the same vertical line so that the shaft cylinders on the door side correspond to each other, and especially when there are three or more hinges, the work becomes extremely difficult. .

Therefore, the length of the pin is shortened stepwise in the upward direction to avoid simultaneous contact of each shaft cylinder portion on the door side with each shaft pin, and a shallow fitting to the shaft pin at the lower end is performed. After the positioning is performed, the method of fitting them one after another is taken.

[0005]

[Problems to be solved by the device]

 By the way, in the case of the method in which the lengths of the shaft pins are stepwisely differently fitted as described above, the difficulty of simultaneous fitting with a plurality of shaft pins can be avoided, but positioning is performed with respect to the lower end shaft pin. After that, alignment accuracy is required for the remaining multiple axis pins that are located on substantially the same vertical line, so there is still some difficulty in working, and the entire weight of the door must be supported until the fitting is completed. I could not avoid the trouble.

In view of the above, the present invention provides positioning for a plurality of remaining shaft pins located on substantially the same vertical line in a state in which the door-side shaft tubular portion corresponding to any one of the shaft pins is completely fitted. Its purpose is to provide a hinge that can be individually handled, thus facilitating installation work and reducing labor.

[0007]

[Means for Solving the Problems]

 This invention was devised to achieve the above-mentioned object, and its characteristic is that the shaft cylinder part of the vane plate on the door frame side is formed so that the shaft pin can be housed in a substantially buried state, and the shaft cylinder part is In the configuration, a spring member for protruding the shaft pin to the use position is provided, and a locking mechanism capable of arbitrarily locking the shaft pin in a substantially buried position against the spring force is provided.

Further, according to this invention, in the locking mechanism, a screw hole formed in the shaft pin in a substantially radial direction, a lever screwed into the screw hole, and a shaft tubular portion on the door frame side are provided. And a guide hole having a shape capable of guiding the lever in the vertical direction and having a shape capable of guiding the lever in the horizontal direction at a substantially buried position.

[0009]

[Action]

 According to this invention, the shaft pin is pushed in against the spring force prior to the door mounting work, and is locked at the substantially buried position by the locking mechanism. Since the shaft pin is substantially buried, any one of the protruding shaft pins can completely fit the shaft cylinder portion on the door side, thereby temporarily supporting the door at a predetermined mounting position. When the locking of the locking mechanism is released in this state, the shaft pin projects due to the urging force of the spring member and advances into the corresponding shaft cylinder portion.

【Example】

 1 to 6 show an embodiment of the present invention. As shown in FIG. 3, the door 4 is rotatably attached to the door frame 2 with three hinges 6, 8, and 10. The hinges 6 and 8 are hinges according to an embodiment of the present invention, and the lowermost hinge 10 is a conventional slip-on type hinge having a vertical adjustment function.

The hinges 6 and 8 have blade plates 12 and 14 fixed to the door frame 2 and the door 4, respectively, and a shaft tube portion integrally formed with the blade plates 12 and 14 by means such as curling. 16, 18; a shaft pin 20 which is removably inserted between the shaft tubular portions 16 and 18; and a coil spring 22 as a spring member provided below the shaft tubular portion 16 on the door frame 2 side. , And a locking mechanism 24 for locking the shaft pin 20 in a substantially buried position.

A collar member 26 having a slit 26a is slidably provided between the shaft tubular portions 16 and 18 so as to be slidable in an up and down direction to cover a gap between the shaft tubular portions 16 and 18. A star 28 is press-fitted into the upper end of the shaft cylinder portion 18 on the door 4 side. The blade plate 12 is fixed to the door frame 2 with a wood screw 30 through a countersink hole 12a, and the blade plate 14 is fixed to the door 4 with a wood screw 30 through a countersink hole 14a. A bottom surface 16a for receiving the coil spring 22 is formed at the lower end of the shaft tube portion 16, and a spring accommodating hole 20a is formed at the lower end portion of the shaft pin 20.

The locking mechanism 24 in this example has a screw hole 20b formed in a substantially radial direction near the center of the shaft pin 20, a lever 32 screwed into the screw hole 20b, and a shaft tubular portion 16. The guide hole 34 is formed. The lever 32 is composed of a screw portion 32a and an operating portion 32b projecting outward of the shaft cylinder portion 16. The guide hole 34 includes a vertical hole 34a for guiding the lever 32 in the vertical direction, and a vertical hole 34a. It is composed of a horizontal hole 34b, which is connected to the vertical hole 34a and serves as a locking hole for guiding the lever 32 in a substantially horizontal direction at a substantially buried position of the shaft pin 20. The lateral hole 34b is slightly inclined to ensure the locking.

As shown in FIG. 4, the hinge 10 has blade plates 36 and 38 fixed to the door frame 2 and the door 4, respectively, and a shaft tubular portion 40 integrally formed with the blade plates 36 and 38, respectively. 42, a shaft pin 44 that is removably inserted between the shaft tubular portions 40, 42, and a vertical adjustment screw 46 that is screwed to the lower end of the shaft tubular portion 40 on the door frame 2 side. There is. Reference numeral 48 indicates a collar member, and reference numeral 50 indicates a star. Reference numerals 36a and 38a indicate countersink holes, and 44a indicates a flange portion for pushing up the door 4.

Next, the operation of using the hinges 6 and 8 will be described. As shown in FIG. 5, prior to the work of attaching the door 4, the lever 32 of the locking mechanism 24 is pulled down against the spring force of the coil spring 22, and the operating portion 32b is engaged with the lateral hole 34b of the guide hole 34. . As a result, the shaft pin 20 is held in a substantially buried position where it does not hinder the shaft cylinder portion 18 on the door 4 side at all.

As shown in FIG. 6, the door 4 is lifted in this state, and the hinge 10 with the shaft pin 44 protruding to the use position is completely fitted. That is, the door 4 is positioned at a predetermined mounting position where all the hinges 6, 8, 10 are fitted to the door frame 2. In this state, when the lever 32 of the locking mechanism 24 of each hinge 6 and 8 is removed from the lateral hole 34b, the shaft pin 20 projects by the urging force of the coil spring 22 and advances into the shaft tube portion 18 as shown in FIG. . When the lever 32 comes into contact with the upper end of the guide hole 34, the use position of the shaft pin 20 is automatically obtained, and then the lever 32 is removed from the shaft pin 20.

As a result, the hinges 6 and 8 are used, and the door 4 is rotatably supported with respect to the door frame 2. Even if the shaft pin 20 does not enter the shaft cylinder portion 18 smoothly, the shaft pin 20 urged by slightly shifting the door 4 automatically enters, so that the work is extremely easy. The fitting operation of the shaft pin 20 does not have to be performed at the hinges 6 and 8 at the same time, and can be performed completely separately. Therefore, even if there are a large number of shaft pins 20 arranged on substantially the same vertical line, they can be easily attached without worrying about the alignment.

Further, since most of the weight of the door 4 is supported by the door frame 2 when the hinge 10 is completely fitted, the work of fitting the hinges 6 and 8 requires the weight of the door 4. Can be performed with almost no influence of. Therefore, the labor of mounting the door 4 can be significantly reduced. In addition, although the example of attaching the lowermost part with the conventional slide type hinge 10 is shown, it goes without saying that all may be the same as the hinges 6 and 8. In this case, not only the lowermost one but any one hinge can be defined as the first positioning hinge for fitting.

Next, FIG. 7 shows another example, in which the locking mechanism 52 has a so-called ball lock structure.

The locking mechanism 52 includes a through hole 20 c formed in the shaft pin 20 in a substantially radial direction, a ball 56 urged by a spring member 54 to be housed in the through hole 20 c, and a spring member 54. The holding member 58 includes a holding member 58, an engaging circumferential groove 16b formed on the inner surface of the shaft tube portion 16, and an unlocking hole 16c formed in communication with the engaging circumferential groove 16b. In addition, the shaft pin 20 is formed with a detent edge 20d for engaging with the vertical clearance of the shaft tube portion 16 generated by the curling process, so that the ball 56 and the unlocking hole 16c can be positioned. It has become.

According to this example, the ball 56 is automatically engaged with the engagement peripheral groove 16b by merely pushing in the shaft pin 20, and the locked state is obtained. When the thin rod member 60 is inserted into the unlocking hole 16d and the ball 56 is pushed while the shaft pin 20 is locked in the substantially buried position, the engagement between the ball 56 and the engaging circumferential groove 16b is detected. The uncoupling is released, and the shaft pin 20 projects by the biasing force of the coil spring 22. In this example, the only component of the locking mechanism 52 that can be seen from the outside is the small-diameter locking release hole 16c, so that the appearance of the hinges 6 and 8 can be minimized as compared with the above example. There are advantages. The engaging circumferential groove 16b is formed prior to the curling process. Instead of the engaging circumferential groove 16b, a mere partial engaging recess may be formed.

In each of the above examples, each constituent element is shown as a particular shape or member, but the present invention is not limited to this, and may be appropriately applied within a range satisfying the locking / unlocking function of the shaft pin 20. It is possible.
