Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a temporary fixing method in a mounting operation of a pair of door mounting parts, ie, a handle assembly, a handle assembly, or a cylinder lock and thumb turn assembly, which are mounted to face both side portions of a door.
[0002]
[Prior art]
A pair of door mounting parts to be mounted opposite to both side surfaces of the door includes a female screw or a male screw, and includes a plurality of first screw rods erected on one door mounting part and a male screw or a female screw. The mounting operation of calling to each other and fixing to both side surfaces of the door by screwing with a plurality of second screw rods inserted through the screw holes of the other door mounting part has been generally used conventionally. It is well known.
[0003]
However, in the above-described mounting operation, the other door mounting component is pressed against the other surface of the door while the one door mounting component is applied to the one surface of the door, and the other is against the first screw rod on the one door mounting component side. When one operator tries to screw the second screw rod through the screw holes of the door mounting parts, the second hand is held with one hand and the second with the other hand. The screw rod must be screwed to the first screw rod, and workability is extremely poor.
[0004]
At this time, the worker had to take a very unstable posture, and sometimes the door mounting parts were dropped and damaged. In addition, when the door is thick, there is a problem that one person cannot work.
[0005]
In order to solve this problem, the applicant of the present application has already proposed a door handle set disclosed in JP-A-7-166739.
[0006]
In the method disclosed in the publication, one door mounting part is brought into contact with one surface of the door, the first screw rod is inserted into the hole of the door, and then press-fitted or screwed into the first screw rod on the ground side of the door. A rigid temporary fixing piece is attached by fitting, and the temporary fixing piece is locked in the vicinity of the hole in the other surface of the door. With this, the temporary attachment piece including the first screw rod is temporarily prevented from falling off the door. It has been stopped.
[0007]
[Problems to be solved by the invention]
According to the method, after one door mounting part is locked with the temporary fixing piece, the first screw rod is supported while supporting only the other door mounting part with the hand even if it is not held by hand. By attaching two screw rods, both attachment parts can be called on both sides of the door.
[0008]
However, until the temporary fixing piece is fitted into the first screw rod, if the hand is released from one of the door mounting parts on one side of the door, it may fall off, and the door is thick and the door mounting part is heavy and large. There are also points to be improved such that it is still difficult for one worker to perform the installation work.
[0009]
The temporary fixing method for mounting a door mounting component according to the present invention has been proposed for the purpose of simplifying the temporary locking operation of one door mounting component to the door and allowing the operator to perform the entire mounting operation alone. It was.

[0018]
Here, the door mounting parts 1 and 2 that make a pair inside and outside the room are called on both side surfaces so as to sandwich the door 10, and the mounting work of the door mounting parts 1 and 2 is completed.
[0019]
The door mounting parts 1 and 2 of the first embodiment shown in FIGS. 1 and 2 represent the handle assembly inside and outside the door, and the door mounting parts 1 and 2 of the second embodiment shown in FIGS. 3 and 4. Represents an assembly comprising a knob 14, a cylinder lock (not shown) and a thumb turn (only the base 21 is shown, and the thumb turn itself is not shown).
[0020]
Further, the door mounting parts 1 and 2 of the third embodiment shown in FIGS. 5 to 7 are similar to the second embodiment in that the knob 14, the cylinder lock (not shown) and the thumb turn (only the base 21 are shown, the thumb turn itself is not shown. The door mounting parts 1 and 2 of the fourth embodiment shown in FIGS. 8 and 9 show the handle assemblies inside and outside the door as in the first embodiment.
[0021]
Both the configuration and the installation procedure described above are well known. The main part of the present invention will be described below.
[0022]
In the first embodiment (see FIGS. 1 and 2), an annular rubber-like elastic body 4 made of an elastic polymer material is fitted in advance around a base side of at least one first screw rod 11 at a factory or the like. It is fixed.
[0023]
In this example, the cross-sectional shape of the rubber-like elastic body 4 is formed in an outwardly convex mountain shape. However, if the overall shape of the rubber-like elastic body 4 is annular, the cross-sectional system is not limited to the mountain shape. Absent.
[0024]
Further, as the means for fixing the rubber-like elastic body 4 to the first screw rod 11, the fitting means using only the elastic force of the rubber-like elastic body 4, the adhering means, or the groove provided around the screw rod 11. Arbitrary means such as a fitting means using an elastic force can be adopted.
[0025]
In the invention of the first embodiment, when one of the door mounting parts 1 is held by hand and the first screw rod 11 on the back surface is inserted into the through hole 40 provided in the door 10 itself, the through hole is accompanied with the insertion. The rubber-like elastic body 4 having an outer diameter larger than the diameter of 40 is once forcibly reduced in the through-hole 40 and elastically restored after passing, so that one of the door mounting parts 1 is released there. However, the rubber-like elastic body 4 acts as a retaining piece for the first screw rod 11 (see FIG. 2).
[0026]
Therefore, even if the first screw rod 11 is pushed slightly in the direction of arrow A due to the screwing of the second screw rod 3, it will never come out due to the presence of the rubber-like elastic body 4 in contact with the inward surface 10a of the door 10. In addition, one of the door mounting parts 1 is surely temporarily fixed to the door 10 without dropping off.
[0027]
In the second embodiment (see FIG. 3 and FIG. 4), the fixing position of the rubber-like elastic body 4 with respect to the first screw rod 11 is around the front end side, and the first screw rod 11 is connected to the through hole 40 of the door 10. In addition, the abutting portion where the rubber-like elastic body 4 acts as a retaining piece when inserted into the hollow support column 30 is not the constituent material of the door 10 but the outward face 20a of the accessory provision 20 of the lock box or other door 10. This is different from the first embodiment. Other structures and operations conform to the first embodiment.
[0028]
In the third embodiment (see FIGS. 5 to 7), the annular rubber-like elastic body 4a is fixed in advance to the inner wall on the front side of at least one hollow column 30 in the lock box 20 fixed in the door. is there. In this example, the cross-sectional shape of the annular rubber-like elastic body 4 is formed in an inwardly convex mountain shape, but the cross-sectional shape is not limited to the illustrated example.
[0029]
As a means for fixing the rubber-like elastic body 4a to the hollow support column 30, any means such as an adhesion means or a fitting means (in this case, a flange portion is provided integrally with the rubber-like elastic body and fitted into the mouth of the hollow support column 30) is adopted. Can do.
[0030]
In the invention of the third embodiment, as shown in FIG. 5 to FIG. 7, the hollow support 30 of the lock box 20 is held through the through hole 40 of the door 10 by holding one door mounting part 1 by hand. Push in with a little stronger force.
[0031]
In the insertion of the first screw rod 11, the annular rubber-like elastic body 4 a having an inner diameter smaller than the outer diameter of the first screw rod 11 generates a slip between the first screw rod 11 and the radial direction. (See FIG. 7).
[0032]
In the state shown in FIG. 7 in which the first screw rod 11 is completely inserted, the first screw rod 11 generates a frictional force with the rubber-like elastic body 4a. Even if the eaves 11 are pushed a little in the direction of arrow A, the escape is prevented.
[0033]
In the invention of the fourth embodiment, as shown in FIGS. 8 and 9, there is provided a cylindrical rubber-like elastic body 4b made of an elastic polymer material around the base side of at least one first screw rod 11. It is fitted and fixed in advance at a factory.
[0034]
The outer diameter of the cylindrical rubber-like elastic body 4b is set to be slightly larger than the diameter of the through hole 40 of the door 10.
[0035]
In the fourth embodiment, as shown in FIG. 9, the rubber elastic body 4 b at the base of the first screw rod 11 is held slightly in the through hole 40 of the door 10 by holding one door mounting part 1 by hand. Fit with force.
[0036]
Then, the rubber-like elastic body 4b is fitted into the through-hole 40 of the door in a state where the elastic elastic body 4b is slightly elastically deformed in the radial direction.
[0037]
In the state of FIG. 9 in which the first screw rod 11 is completely inserted, a frictional force is generated between the rubber-like elastic body 4b fixed to the first screw rod 11 and the inner peripheral edge of the through hole 40 of the door, and accordingly Even if the first screw rod 11 is pushed a little in the direction of the arrow A due to the screwing of the second screw rod 3, the withdrawal is prevented.
[0038]
In short, the one door mounting part 1 is surely temporarily fixed to the door 10 via the lock box 20 fixed thereto without dropping off.
[0039]
【The invention's effect】
As described above, according to the temporary fixing method for mounting a door mounting component according to the present invention, a pair of door mounting components that should be mounted to face both side portions of the door are called with a screw rod to the door. In the process of attaching, one of the door attachment parts is temporarily fixed to one side of the door. The annular rubber-like elastic body exhibiting a temporary fixing action is previously attached to the first screw rod or the hollow column of the lock box at a factory or the like. Since it is fixed, there is an advantage that the temporary fixing operation can be automatically performed only by pressing the first screw rod erected on one of the door mounting parts slightly stronger from one surface of the door.
[0040]
Therefore, unlike the conventional example in which the temporary fixing piece is mounted on the site, it is possible to improve the workability by reducing complicated work on the site, and even a single operator can remove one door mounting part from the door. There is an effect that the fall damage can be surely eliminated in the whole process of installation.
