Description

  The present invention relates to a door frame structure, and more particularly to a door frame vertical frame structure.

  Conventionally, the structure of the vertical frame of the door frame attached to the opening of the wall is generally configured by fixing a door stop member separate from the vertical frame main body to a part of the inner surface of the vertical frame main body in the width direction. Or, the door stop protrusion is provided integrally at the center of the inner surface of the frame body in the width direction, but the former only requires time and effort to attach another door contact member to the vertical frame body. In any case, since the portion that becomes the door contact protrudes to the center in the width direction and is narrow, there is a risk of damage if a large impact is applied to the door contact portion when the door is closed.

  Therefore, by forming a paragraph portion for positioning the end portion of the door when the door is closed by paragraphing one side portion in the width direction of the inner surface side of the vertical frame of the door, the step portion of the paragraph portion is formed. Patent Document 1 proposes door-to-door.

  That is, the conventional vertical frame shown in the above-mentioned Patent Document 1 forms a paragraph portion by dividing one side of the inner surface of the vertical frame, and one of both side surfaces of the vertical frame is exposed to one room. In addition to the first indoor exposed surface portion, the other side surface portion of the both side surface portions of the vertical frame is a second indoor exposed surface portion that is exposed to the other room.

In the conventional example shown in Patent Document 1, a step portion is formed at the end portion of the paragraph portion by forming a paragraph portion in the door frame, and the width direction of the inner surface portion of the frame body is Compared with the door projections in the center, the width of the part that becomes the door stop is wider, the strength of the door stop is strong, and the manufacturing is easy. Since the paragraph portion is formed on one side of the inner surface, the width (found width) of the first indoor exposed surface exposed in one room and the second indoor exposed surface exposed in the other side of the other side Unlike the width (finding width), the appearance of the vertical frame in one room is greatly different from the appearance of the vertical frame in the other room with the door closed, giving a steep feeling. There was a problem.
Utility Model Registration No. 3129499

  The present invention was invented in view of the above-described conventional problems, and the structure of a door frame that has the same appearance as the width of the vertical frame in one room and the width of the vertical frame in the other room. It is a problem to provide.

  In order to solve the above problems, a door frame structure according to the present invention is a door frame 5 attached to an opening 4 for entering and exiting between one room 1 and the other room 2, and the door frame. When the door 7 is closed on one side of the inner surface of the vertical frame 6 and the door 7 is closed, a paragraph portion 8 is formed in which the end of the door 7 is positioned. The side surface portion on the side is a first indoor exposed surface portion 9 exposed in one room, and one end portion in the width direction of the first indoor exposed surface portion 9 protrudes from the outer surface of the vertical frame 6 toward the opposite side to the paragraph portion 8. It is comprised by the outer surface side protrusion part 10, and the other side surface part among the both side surface parts of the vertical frame 6 is made into the 2nd indoor exposure surface part 11 exposed to the other room 2, and the width M1 and 2nd of the said 1st indoor exposure surface part 9 are 2nd. It is characterized in that the width M2 of the indoor exposed surface portion 11 is made equal.

  In this manner, by forming the paragraph portion 8 where the end portion of the door 7 is positioned when the one side portion side of the inner surface portion of the vertical frame 6 is paragraphed and the door 7 is closed, the end portion of the paragraph portion 8 is formed. The step 8a portion can be a door stop, which is stronger than a member that fixes a separate door stop member and does not require a separate door stop member. In addition, as described above, by forming one side portion side of the inner surface and forming the paragraph portion 8, the thickness of the portion where the paragraph portion 8 is formed and the portion where the paragraph portion 8 is not formed are different. One end portion in the width direction of the first indoor exposed surface portion 9 is constituted by an outer surface side protruding portion 10 that protrudes from the outer surface of the vertical frame 6 toward the opposite side to the paragraph portion 8, and the lateral width M1 of the first indoor exposed surface portion 9 and the first Since the horizontal width M2 of the two indoor exposed surface portions 11 is made equal, the widths of the vertical frames 6 seen from the one room 1 and the other room 2 are the same, and the appearance is improved.

  Since the present invention is configured as described above, one side of the inner surface of the vertical frame is formed on one side of the frame and the end of the door is positioned when the door is closed. The appearance width of the vertical frame exposed in the room is the same as the width of the vertical frame exposed in the other room, and the appearance is improved.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  The door frame 5 according to the present invention includes a left and right vertical frame 6 and an upper horizontal frame 12 that connects the upper ends of the left and right vertical frames 6 in a gate shape, and a left and right vertical frame. 6, an upper horizontal frame 12 that connects the upper ends of the left and right vertical frames 6, and a lower horizontal frame (not shown) that connects the lower ends of the left and right vertical frames 6 are formed into a rectangular frame shape. Some are composed.

  In the embodiment shown in the accompanying drawings, a door frame 5 configured by framing the left and right vertical frames 6 and the upper horizontal frame 12 connecting the upper ends of the left and right vertical frames 6 in a gate shape will be described as an example. .

  The vertical frame 6 is a first indoor exposed surface portion 9 where one side surface portion of both side surface portions is exposed to one room 1, and the other side surface portion is a second indoor exposed surface portion 11 exposed to the other room 2. .

  As shown in FIG. 2, the vertical frame 6 is formed when one side of the inner surface of the frame body 6 a having a rectangular horizontal cross section constituting the main body of the vertical frame 6 is closed and the door 7 is closed. The paragraph part 8 for the edge part of this to be located is formed, and by forming the paragraph part 8, the level | step difference 8a part is a door stop. By providing the paragraph portion 8 in this manner, the thickness t1 of the portion of the frame body 6a having the rectangular horizontal section 6a where the paragraph portion 8 is provided is larger than the thickness t2 of the portion of the frame body 6a where the paragraph portion 8 is not provided. It is getting thinner. An outer surface side protruding portion 10 projects from an end portion of the outer surface portion of the frame body 6a (that is, the surface opposite to the inner surface portion on which the paragraph portion 8 is formed) toward the opposite side of the paragraph portion 8. One side surface portion of the frame body 6a and the side surface portion of the outer surface side protruding portion 10 are continuously flush with each other to form a first indoor exposed surface portion 9 that is exposed to the first room. That is, the first indoor exposed surface portion 9 is configured by a side surface portion of the frame body 6a and a side surface portion of the outer surface side protruding portion 10 that are continuous in the width direction (in other words, one end portion of the first indoor exposed surface portion 9). Is constituted by the outer surface side protruding portion 10).

  In the present invention, the lateral width M1 of the first indoor exposed surface portion 9 and the lateral width M2 of the second indoor exposed surface portion 11 are made equal.

  As shown in FIGS. 1 to 3, the door frame 5 including the vertical frame 6 having the above-described configuration is attached to the opening 4 for entering and exiting between the one room 1 and the other room 2.

  Here, the vertical frame 6 is attached as shown in FIG. 2 so as to cover the end surface portion on the opening portion 4 side of the wall 3 partitioning between the one room 1 and the other room 2, and the first indoor exposed surface portion 9. The outer surface side protruding portion 10 constituting one end portion in the width direction is attached so as to overlap the end portion on the opening 4 side of the wall surface of the wall 3 of one room 1.

  FIG. 2 shows a state in which the door 7 is closed. With the door 7 closed, the end of the door 7 is positioned in the paragraph 8 and the step 8 a at the end of the paragraph 8 is a door stop. With the door 7 closed, the horizontal width M1 of the first indoor exposed surface portion 9 and the horizontal width M2 of the second indoor exposed surface portion 11 which are portions exposed to the one room 1 and the other room 2 of the vertical frame 6 are equal. Therefore, when the door 7 is closed, the width of the vertical frame 6 when the vertical frame 6 is viewed from one room 1 and the width of the vertical frame 6 when viewed from the other room 2 are as follows. It becomes equal, there is no sense of incongruity, and the appearance is improved.

  In the embodiment of FIG. 3, the upper horizontal frame 12 is attached to the lower surface of the ceiling 13 directly or via a spacer 14. In this embodiment, the upper horizontal frame 12 is an example in which no door stop is formed.

  As shown in FIG. 4, one end portion in the width direction of the lower surface of the upper horizontal frame 12 is divided to form the upper paragraph portion 15, and when the door 7 is closed to the upper paragraph portion 15, the upper end portion of the door 7 is While being positioned, the step 15a at one end of the upper paragraph 15 may be the upper door stop where the upper end of the door 7 hits.

  In FIG. 4, the width of the exposed surface portion exposed on one room 1 side of the upper horizontal frame 12 is different from the width of the exposed surface portion exposed on the other room 2 side. Since it is attached, when it sees the opening part 4 from the one room 1 and the other room 1, it exists in the place which is not so conspicuous, Therefore Even if the width | variety of an exposed surface part differs, there is no sense of incongruity.

  In addition, as shown in FIG. 5, a narrow door projection 17 may be provided integrally with the upper horizontal frame 12 so as to protrude downward at the center in the width direction of the lower surface of the upper horizontal frame 12.

  In general, the upper horizontal frame 12 has a shorter length than the vertical frame 6 as shown in FIG. 1A. Therefore, the impact when the door 7 is closed is not applied to the vertical frame 6 side. Even if a narrow door stop protrusion 17 is provided at the center of the lower surface of the upper horizontal frame 12 in the width direction, the narrow door protrusion 17 is provided at the center of the inner surface of the vertical frame 6 in the width direction. Problems with strength, such as when projecting, are unlikely to occur.

  FIG. 6 shows another embodiment of the present invention, showing an example in which recesses 19 for fitting wall surface plates are provided on both sides of the outer surface of the vertical frame 6. The end of the wall plate 21 and the end of the wall plate 21 of the other room 2 are fitted in the recesses 19 for fitting the wall plate so that the edge line of the wall plate 21 is not exposed.

The attachment of the door frame of this invention is shown, (a) is a front view, (b) is a plane sectional view, (c) is a longitudinal sectional view. It is an expanded sectional view of the attachment part of the vertical frame same as the above. It is an expanded sectional view of the attachment part of an upper horizontal frame same as the above. It is an expanded sectional view of the part which attached the upper horizontal frame of other examples. Furthermore, it is an expanded sectional view of the part which attached the upper horizontal frame of the other example. It is an expanded sectional view which shows the attachment part of the vertical frame of the other example of this invention.
