Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a width adjustment device for a door body used in a house or the like.

[Problems to be solved by the prior art and the invention] In general, even in today's day when buildings are standardized, this type of door body is still subject to the standards for Kanto, Kansai, Shikoku, Kyushu, etc. depending on the region. Furthermore, even in the same region, the dimensions of the pillars are 3 sun, 3 sun 5 minutes, and 4 sun.
A variety of sizes are used, such as 3-inch, 4-inch, 5-inch, etc. Therefore, even if the distance between the pillar cores is the same, the fitting dimensions between the pillar surfaces will vary. However, conventionally, when installing a door body in a place with different fitting dimensions, if the door body is made of wood, it can be shortened by cutting the standard one, but this work is troublesome and Some items, such as those made of decorative materials, cannot be cut, and some metal door bodies cannot be cut, so expensive items with special instructions must be used. figure,
However, there were drawbacks such as poor workability and lack of economy.

Therefore, a device has been proposed in which the end member of the side edge of the door body can be adjusted in left and right width, but when installing a grip ball with a latch on this device, the grip ball rod must be installed through the door body. Moreover, since it is necessary for the latch to protrude from the side edge of the door body, when the width of the side edge of the door body is adjusted and the grip position needs to be moved accordingly, the amount of protrusion of the latch will be different. ,on the other hand,
When the gripping ball position is moved, the penetrating position of the gripping ball rod changes, resulting in a problem in assembly.

[Means and effects for solving the problem] The present invention was created in view of the above-mentioned circumstances with the aim of providing a door body width adjustment device that can eliminate these drawbacks.
A fixed body fixed to one side edge of the door body and a movable body disposed outside the fixed body form an end member of the one side edge of the door body, and the movable body is connected to the movable body. A lock body formed to be movable in the left and right directions with respect to a fixed body by rotational movement of a screw body from the outside, so that the left and right width of the door body can be changed, and having a latch on the side where the left and right width can be changed. To install the lock, the lock body is integrally attached to the movable body side, and an engagement hole for the gripping ball rod is bored at the tip of the latch mounting base at a position on the inside of the door body relative to the movable body. The insertion hole drilled in the door surface plate for the ball rod to pass through is made into an elongated hole that is long in the left and right direction to accommodate the movement of the ball grip rod based on the left and right movement of the movable body. , is characterized by having a large diameter so as to hide the insertion hole in the range where the gripping ball rod moves from one end to the other end of the insertion hole.

With this configuration, the present invention makes it possible to maintain the position of the grip ball at a constant distance from the adjusted edge of the door body even when the left and right width of the door body is adjusted. It is.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawing, reference numeral 1 denotes a door body, and front and rear surface plates 2 forming the door body 1 face each other with a predetermined interval, and their edge portions 2a are directed inward. It is bent. Reference numeral 3 denotes a fixed body provided on the edge of the door end of the door body 1, and a locking groove 3a is formed near the outer end of the fixed body 3.
The end edge 2a of the surface plate is fitted into and locked into this locking groove 3a. Further, in the door body 1 of this embodiment, a member such as a honeycomb core or foamed polyurethane resin is filled as a filler material 4 between the surface plates 2, so that the door body 1 has a predetermined thickness. It is set.

Reference numeral 5 denotes a movable body disposed apart from the fixed body 3, and screw holes 5a and 3b with opposite screw threads are bored between the movable body 5 and the fixed body 3, respectively. It is set up. Reference numeral 6 denotes a screw body, and the screw body 6 has screw grooves 6a and 6b with reverse threads corresponding to the screw holes 5a and 3b described above, and is screwed into the screw holes 5a and 3b, respectively. ing. Reference numeral 7 denotes an edge material having a substantially U-shape;
The edge of the door body 1 on the door end side is covered by cover fitting, and the inner edge is covered with the movable body 5 at the farthest distance from the fixed body 3, as will be described later. It is designed to reach at least the position of the locking groove 3a of the fixed body 3, that is, the position of the end edge of the surface plate 2. The edge material 7 is integrally fixed to the movable body 5 by screwing, and the edge material 7 is provided with an insertion hole 7a corresponding to the screw body 6. and screw body 6
can be rotated by inserting a tool such as a screwdriver from the outside of the movable body 5, i.e. from the outside of the edge material 7, thereby causing the movable body 5 to rotate the screw body 6 with respect to the fixed body 3. It is designed to move relatively left and right within a range, and to adjust the left and right width of the door body 1.

On the other hand, 9 is a lock body, and the lock body 9 is attached to the door body by screwing a latch mounting base 10 provided with a latch 9a to the movable body 5.
The latch mounting base 10 has an engagement hole 1 through which the gripping ball rod 11a is inserted.
0a is drilled. In addition, the surface plate 2 is provided with an insertion hole 2a through which the ball gripping rod 11a is inserted. It is a long hole extending from left to right. Moreover, the gripping ball mounting base 11b has an insertion hole 2a in a range where the ball gripping rod 11a moves from one end of the insertion hole 2a to the other end.
The diameter of the insertion hole 2a is large so that it can be hidden from view, so that the insertion hole 2a cannot be visually seen from the outside.

In the embodiment of the present invention configured as described above, when installing the door body 1, if the installation dimensions do not match the left and right dimensions of the door body 1, use a tool such as a screwdriver to drill into the edge material 7. insertion hole 7
When the screw body 6 is rotated by inserting it from a, since the screw body 6 is screwed into the movable body 5 and the fixed body 3 in a reverse thread relationship, the movable body 5 will not move relative to the fixed body 3. This allows the door body 1 to be relatively easily and reliably adjusted to an appropriate size suitable for the installation location. Therefore, it is sufficient to attach this thing to the opening.

In this way, in the case of the present invention, even if the door body is made of a steel plate and the side edges cannot be cut, the left and right dimensions of the door body 1 can be adjusted by the threaded body 6. It can be easily and accurately adjusted on-site according to the installation location by only the extremely simple rotation operation of the . Therefore, instead of having to manufacture the door body 1 one by one for each site, it is possible to set and manufacture several door bodies 1 in advance using appropriate sizes as standards, and then use these as standards to create any desired door body 1. The mounting dimensions can be freely adjusted, which greatly simplifies product management and enables mass production, resulting in significant cost reductions. Furthermore, even when the left and right dimensions are adjusted, the left and right edges of the door body 1 are always covered with the edge material 7 and the fixed body 3, movable body 5, etc. are never exposed, so before and after adjustment. There is absolutely no change in appearance or functionality.

Moreover, when the left and right width of the door body 1 is adjusted, the gripping rod 11 is attached to the adjusted side.
a moves through a horizontally long insertion hole 2a drilled in the surface plate 2 based on the horizontal movement of the movable body 5.
Even if the left and right width of the door body is adjusted, it can always be kept at a constant distance from the adjusted edge, and there is no problem that the position of the grip ball 11 will shift due to adjusting the width of the door body. . Moreover, the insertion hole 2a
Although it has a long hole to accommodate the movement of the ball-gripping rod 11a, it is hidden by the ball-gripping mounting pedestal 11b, so the ball-gripping mounting pedestal 11b
can be effectively used as a blinding member for the insertion hole 2a, and even without using a separate blinding member, the appearance will not be impaired in any way and ease of assembly can be improved.

It should be noted that the present invention is of course not limited to the above-mentioned embodiments, and may be adjustable on both the left and right sides. Furthermore, the movable body is not limited to the one in which the movable body is screwed with a reverse screw as in the above embodiment. For example, as shown in FIG. material 13, and both edge materials 12 and 13 constitute the edge body of the door body,
The screw body 14 is configured to be able to rotate freely around the axis with respect to the movable edge material, but is restricted from moving in the axial direction, and is configured to be screwed into the fixed edge material 13, and is configured to be screwed into the fixed edge material 13. 1 bullet between 12 and 13
5, the movable edge member 12 will automatically move in the left and right direction by the rotation of the screw body 14.
This also allows the left and right width of the door body to be adjusted, and it is also possible to use something like this.

[Operation and Effect] In short, the present invention is constructed as described above, so if the left and right width of the door differs from the installation dimension, the screw body can simply be rotated from the outside of the movable body. The left and right width of the door body can be reliably changed with an extremely simple operation.
Therefore, it is possible to easily change the dimensions of a standard door body in a non-standard part on-site, without having to manufacture a non-standard door body each time or cutting the side edges on-site to match the installation dimensions as in the past. At the very least, it can be installed, which not only significantly improves work efficiency and enables mass production, but also simplifies product management and reduces costs.

Moreover, in this case, when the left and right width of the door body is changed, the gripping ball rod of the lock body that is attached to the movable body on that side has a long insertion hole drilled in the left and right direction on the surface of the door body. Therefore, even if the left and right width of the door body is adjusted, the position of the grip ball can always be kept at a constant distance from the adjusted edge, and the grip ball can be moved at a constant distance from the adjusted edge. There is no problem of the position shifting due to adjusting the width of the door body. Moreover, even though the insertion hole is a long hole to accommodate the movement of the ball rod, it is hidden by the ball mounting base.
The gripping ball mounting base can be effectively used as a blinding member for the insertion hole, and even without using a separate blinding member, the appearance is not impaired in any way, and the ease of assembly can be improved.
