Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a width-adjustable door device that can be applied to various doors such as wardrobe doors, furniture doors, doors, and sliding doors.

<Conventional technology> In general, doors such as wardrobes and furniture that are installed as furniture, entrance doors, sliding doors, etc. The size is affected by the difference in the dimensions of the pillars, and considering the differences in the thickness of the pillars and the twisting of the pillars themselves, we manufacture a large number of standard doors (stock).
It has become difficult to keep it that way.

〈Problem that the invention aims to solve〉 In other words, in the past, many of these types of doors were so-called custom-made products, which were dimensioned according to the installation location (on-site) and were manufactured and processed on a case-by-case basis, just like the manufacture and installation of fittings. It is troublesome and has flaws that make it expensive.

In view of the above-mentioned circumstances, this invention has been developed using multiple door bodies (2
A door device for mounting furniture, etc., which solves the above problem by dividing the door body into 3 pieces, and making each divided door body into a tongue-and-groove shape, and adjusting the width of the entire door by adjusting the threading degree of the horizontally inserted tightening bolt. The purpose is to provide the following.

<Means for solving the problem> A split door body consisting of two or three pieces having an appropriate length is formed, and a width adjustment groove is provided on the end surface of the mating part of the split door body on one side, and An insertion tube for passing through a tightening bolt that reaches the end of the width adjustment groove is provided in the split door body, and the end of the width adjustment joint door that will become another split door body is fitted into the width adjustment groove, and this width adjustment joint is fitted. Thread the threaded end of the tightening bolt that passes through the insertion tube of the split door body into the receiving screw tube inserted horizontally into the door section, and adjust the width by changing the fitting amount of the width adjustment joint door section by the degree of screw insertion. A reinforcing collar member is attached to the edge of the width adjustment groove.

<Function> Due to the above configuration, multiple sheets (2 to 3 sheets)
In the split door body, the split door body with the width adjustment groove part is connected to the split door body with the width adjustment joint part in a tongue-and-groove shape, and the tightening bolt that can pass through one of the split door bodies is connected to the opposite split door body. The fitting width of both split door bodies can be adjusted according to the degree of screw insertion, and the width of the door can be adjusted when the door is connected and assembled. In this case, when the split door main body is configured with three pieces, the split door main body at the intermediate position becomes the width adjustment joint door part itself, and width adjustment grooves may be formed at the ends of the split door main bodies disposed on both sides.

<Example> Hereinafter, the present invention will be explained based on the drawings of the example.

Figures 1 to 3 show an example in which three divided door bodies are used, 1 and 2 are divided door bodies with appropriate lengths arranged on both sides, and the divided door bodies 1 and 2 are opposite to each other. Width adjustment grooves 4 having a predetermined depth are formed on the side end faces over the entire longitudinal direction, and the split door main body 3 disposed at an intermediate position slides into the groove width a of the width adjustment groove 4. The width adjustment joint door part 5 has a single plate structure with a plate thickness b that allows dynamic fitting. Reference numeral 6 denotes a tightening bolt that penetrates horizontally at three locations at the top, bottom, and center of the left and right split door bodies 1 and 2, and the bolt head 6a of the tightening bolt 6 is drilled into the end face of the split door bodies 1 and 2. The fixing nut 10 protrudes from a loose hole 9 of a mounting seat 8 to be fixed to the recess 7 . Reference numeral 11 denotes an insertion tube for passing through a tightening bolt, which is embedded in the split door bodies 1 and 2. Reference numeral 12 denotes a receiving screw tube inserted laterally into the upper, lower, and center positions of the split door main body 3, which serves as an intermediate door member. , 2 side, the threaded portion 6b of the tightening bolt 6 is screwed in to form an assembly-type door device 13 in which the divided door bodies 1, 2, and 3 are made into a single plate.

Next, I will explain this effect. First, when installing this prefabricated door device 13, measure the frontage or stile width of the pillar A in advance, and set the door width corresponding to the dimension.

That is, in the divided door bodies 1, 2, 3, which are configured as a three-piece assembly, - or + grooves are pre-carved in the bolt heads 6a of the tightening bolts 6 facing the outer end surfaces of the divided door bodies 1, 2 on both sides. If you hold a tightening tool such as a screwdriver (not shown) and rotate it appropriately, the split door body will become the intermediate width adjustment joint door portion 5 into which the threaded portion 6b of the tightening bolt 6 is screwed. 3, the middle split door main body 3 on the side of the receiving screw 12 is substantially pushed in or retreated, and the width of the entire door device 13 is adjusted. The tightening bolt 6 can be fixed by turning the fixing nut 10 of the bolt head 6a protruding from the mounting seat 8 after a predetermined turning operation, and pressing the bolt head 6a against the mounting seat 8. Of course, this width adjustment operation is performed little by little for each tightening bolt 6 in the upper, lower, and center positions. If necessary, an appropriate collar member 14 may be attached to the periphery of the width adjustment groove 4 to provide a reinforcing structure for the width adjustment joint door 5 (see FIG. 4).

In this way, the door device 13 which has become the predetermined width l,
It can be attached by holding a known mounting fitting 15 such as a hinge.

Figures 6, 7, and 8 show other embodiments in which a split door body is divided into two parts. In this case, a width adjustment groove 4 similar to that described above is formed on the end face of one split door body 1, and the other split door body 2 facing
A width adjusting joint door part 5 is integrally protruded from the end face of the split door body 2, and a tightening bolt 6 is passed through the upper, lower, and center positions of one split door body 2, and the threaded part 6b of the tightening bolt 6 is inserted into the opposite side. It is screwed into the receiving screw tube 12 buried in the split door main body 1. Reference numeral 11 indicates an insertion tube for passing through a tightening bolt similar to the above.

At this time, the width adjustment operation of the door device 13 is performed in the same manner as described above, by appropriately turning the bolt head 6a of the tightening bolt 6 facing the end of the split door main body 2, and inserting the screw portion 6b at the tip into the receiving screw of the opposing split door main body 1. By changing the degree of screw insertion into the tube 12, the amount of fitting of the width adjusting joint door portion 5 changes, and the door width is adjusted by drawing the divided door bodies 1 and 2 together or pulling them apart.

<Effects of the invention> As mentioned above, the width-adjustable door device of the present invention divides the door itself into two or three parts, and each divided door body is provided with a tightening bolt that is inserted horizontally and a corresponding receiving screw. By adopting a width sliding structure with a pipe, the door width can be easily and reliably adjusted by simply turning the tightening bolt facing the end of one split door body. , the door will be adapted to different widths. Moreover,
In this case, the width adjustment is performed using a plurality of tightening bolts arranged at the top, bottom, center, etc., so that it is also possible to make partial fine width adjustments such as by twisting the pillar. In addition, because of the fitting and assembly structure of the split door body, for example, in the case of a 3-piece split type, it is possible to change the structure, color, etc. of the split door body, which is the width adjustment joint door part used in the center, so you can easily change the color. You can have fun with it, and the center part can be made with different structures such as a louver or a glass plate, making it a door that suits the age of diversifying hobbies, making it ideal for furniture doors, doors, sliding doors, etc. Of course, the length of the door can be adjusted by cutting it to a predetermined size as appropriate. Further, since the door of the present invention has a simple structure, it can be adjusted with just one screwdriver, and has practical effects such as easy on-site work.
