ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a frame that is placed at an opening portion in a partition provided in houses and the like, and particularly relates to an adjustable frame material capable of adjusting the spacing between a frame and a building frame and further adjusting a width of the frame.
2. Description of the Related Art
In constructing houses and the like, when a door or a window is desirably disposed in a partition of an outside wall or an divider wall, a frame is initially located at an opening portion provided in the partition. The frame should be placed with great accuracy for installation so that a door or a window which is later installed within the frame can be smoothly opened and closed. In order to do so, the frame adjustment is carried out.
FIG. 7
illustrates the state of a conventional adjusting construction work for installing a frame. In
FIG. 7
, reference numeral
21
shows an opening portion formed in a partition
22
. The opening portion
21
is formed in a rectangular manner to extend vertically upwards from a floor
24
with a pillar of the partition
22
or a building frame
23
in an divider member. A frame
25
is located inside the opening portion
21
, a spacing is formed between an outer periphery of the frame
25
and an inner periphery of the building frame
23
, and packing members
26
are close-fitted into plural portions of the spacing. Accordingly, the frame
25
can be fixedly bonded to the building frame
23
.
The fixedly bonded frame
25
may be adjusted with accuracy for installation by the packing members
26
. For the packing members
26
are used thinned wooden pieces such as construction remaining, veneer plate pieces or wedge-shaped wooden pieces. One or more pieces of the packing members
26
is, portion by portion, inserted to and removed from plural portions of the spacing between the frame
25
and the building frame
23
that extends right and left vertical upwards and is formed at the upper lateral side therebetween. This work is repeated manually to realize a fine adjustment such as some millimeter adjustment. When accuracy for installing the frame
25
is realized, the packing members
26
are affixed by adhesive or screwed to finish the adjustment. As a result, the frame
25
has been fixedly bonded to the building frame
23
.
A method of executing a conventional frame adjustment having the foregoing arrangement has disadvantages as below. That is, in order to obtain great accuracy for installation, such a fine adjustment as inserting the packing members into and removing the packing members from plural portions of the spacing requires a skill as well as a long time-consuming manual work. Also, once the adjustment is finished, the thus bonded packing members cannot be readily removed. Accordingly, the readjustment cannot be made for inaccuracy for installation that occurs after the adjustment or for frame deformations.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the prior art, an object of the present invention is therefore to provide a frame that is placed at an opening portion in a partition provided in houses and the like, and specifically an adjustable frame material capable of readjustment with a simple and short-time work but no requirement of a skill.
Another object of the present invention is directed to a width adjustable frame material for making it possible to adjust the width of the frame material so as to be adaptable for the wall thickness (thickness of the building frame) of the opening portion that the frame is to be installed.
Conventionally, as a frame material used for houses and the like should be adapted for walls having different levels of the wall thickness at different building site, so-called ready-made or existing frames are in common used that have certain predetermined widths corresponding to various levels of the wall thickness.
Also, recently, as indicated in
FIG. 12
, a frame material that is called an adjustable frame was invented and has been widely employed for adjustment in which a frame material body
1
is provided with an adjusting groove
3
at an either side or the both sides thereof. The end portions of casing members
2
are taken in and out at the groove
3
corresponding to the wall thickness W, so that the width of the frame can be adjusted. Accordingly, a single type of the frame material may be adaptable for a certain range of the wall thickness W. When these frame materials are used for a door, the frame materials with a door stopper
4
attached thereto may be employed. In
FIG. 12
, reference numeral
34
denotes a pillar (or a building frame) and reference numeral
35
wall members.
However, the conventional frame materials as described above include the following disadvantages.
(1) Various types of frame materials are required:
Since only one ready-made frame having a certain width must be used for a corresponding level of the wall thickness, various types of frame materials matching with each of the different levels of the wall thickness are required.
(2) Removing is not possible:
Both the ready-made frame and the adjustable frame are firmly secured to a pillar or the like by using nails or an adhesive, it would not facilitate removing an unnecessary door frame during modification construction, etc. If such a door frame is forcibly removed, the door frame is subjected to breakage, incapable of being reused.
(3) A protruding door stopper is nuisance:
In both cases of the ready-made frame or the adjustable frame, since the door stopper
4
that impacts on a door when the door is closed is commonly affixed inside the door frame in an independent manner, the door stopper
4
is caused to project from the door frame, the protruding door stopper being made nuisance in the design. The door stopper
4
may also be broken because the stopper prevents one product to be delivered from passing through the frame.
(4) The large number of members to be installed at construction places are necessary and accuracy for installation is required:
The adjustable frame having an adjusting portion at the both sides thereof is so arranged that the casing members
2
are taken in and out at the adjusting groove
3
, and various types of the casing members
2
are prepared. Therefore, the adjustable frame may be adapted for considerble levels of the wall thickness W. However, there are at least four members, that is, a frame material body
1
, two casing members
2
and a door stopper
4
, necessary for installation. In addition, the frame material body
1
must be properly mounted at the center portion of the wall thickness W. If any delocation therefrom occurs, the range capable of being adapted for the wall thickness W would be brought narrower, and further in view of the appearance, either one of the ends of the casing members
2
is protruded from the either side of the frame material body, resulting in inconvenience for the construction work.
(5) Possible defects occur:
The ready-made frame is firmly secured by utilizing both nails and adhesive at the time of fixing. The position of hammering nails in the adjustable frame is adjusted by taking the casing members
2
in and out at the casing members
2
from the adjusting groove
3
. Then, such ways are adopted in common that the nails are hammered into an installed groove
5
for the door stopper
4
in the frame material body
1
, or nails are hammered in angular directions with respect to the adjusting grooves
3
, or otherwise from the back surface in an angular manner. On the other hand, in the ready-made frame, such ways are generally used that the nails are hammered from the back surface in an angular manner or otherwise finishing nails are driven from a hidden portion on a decorative surface. For any of the aforementioned ways, however, since a hammer or an automatic nailer is used for hammering nails, there is a fear that the decorative surface is subjected to defects.
(6) Possible delocation occurs at constructing time
