Description

Door device easy to disassemble and assemble

Technical Field

Background

A conventional door is pivotable between an open position for opening the doorway and a closed position for closing the doorway, and in order to support the door to be pivotable, two sets of hinge devices are generally provided between the door and the doorframe. The hinge device requires a hole to be drilled at a correct position of the door and the door frame due to the screw locking, however, such a work is not easy, and there is a possibility that the door cannot be pivoted to a closed position after being installed or the operation of the door is not smooth due to incorrect positions of the drilled holes. Furthermore, doors using such hinge assemblies are inconvenient and time consuming to install or remove (e.g., to replace or repair the door).

In addition, the hinge assembly for a general door is usually exposed between the door and the door frame, and thus, the hinge assembly is easily corroded by water to cause a non-smooth operation, or the exposed hinge assembly may cause a non-smooth operation due to dust.

In addition, a commercially available folding door needs to be equipped with a rail and roller mechanism, and the rail and roller mechanism for such folding door usually adopts a design of hanging folding door, in other words, the opening of the rail is usually narrower than the rail itself, so that the roller mechanism installed in the rail cannot be directly separated from the rail from the opening, and therefore, the commercially available folding door needs to be disassembled from or installed inside the door frame, and the roller mechanism needs to be disassembled or installed in addition to the two hinge devices, so that the commercially available folding door is inconvenient to disassemble or install.

513, 515. the door-closing positioning mechanism 492 also includes a positioning member 533 movably engaged with the sliding sleeve 511, the positioning member 533 including an arcuate top surface 535.

The second portion 515 of the sliding sleeve 511 is engaged with the positioning member 533, and the positioning member 533 is located outside the base 493, and a spring 519 for biasing the sliding sleeve 511 is received between the sliding sleeve 511 and the bottom cover 531, and the shoulder 517 cooperates with the step surface 499 to prevent the positioning member 533 from being disengaged from the base 493.

The base 493 of the door-closing positioning mechanism 492 is received in the receiving chamber 297A of the pivotal plate 297, the positioning member 533 is disposed outside the pivotal plate 297, the positioning member 533 is movable relative to the pivotal plate 297 between a first position engaging with the track 237 and a second position disengaging from the track 237, and the spring 519 biases the sliding sleeve 511 to bias the positioning member 533 to the first position.

Assuming for convenience of description that the door 295 is in a closed position substantially parallel to the lateral frame mechanism 233, the pivoting plate 297 and the moving plate 333 are aligned, the closing frame 338 abuts against the closing side frame 275 (see fig. 6 and 7), and the positioning member 533 of the door closing positioning mechanism 492 is in the first position and engaged with the rail 237, in such a state that the door 295 can be maintained in the closed position even though the latch 68 is in the unlatching position. Referring to fig. 8, the positioning member 533 of the door closing positioning mechanism 492 is located at the first position to engage with the rail 237 and the latch 68 is located at the latching position such that the door 295 is positioned at the closing position to prevent the door 295 from moving from the closing position to the opening position.

When the operating button 157 is used to drive the latch 68 to move from the latching position to the unlatching position, the door 295 can be pushed to pivot from the closed position to the open position, during the process of pivoting the door 295 from the closed position to the open position, the arc-shaped top surface 535 of the positioning member 533 of the door closing positioning mechanism 492 is pressed by the rail frame 235 to move from the first position (shown in fig. 9) to the second position (shown in fig. 9A) separated from the rail 237, the pivoting plate 297 and the moving plate 333 are further pivoted relatively, and the roller 475 of the roller mechanism 439 rolls along the rail 237 of the rail frame 235 until the door 295 is moved to the open position, and an acute angle is formed between the pivoting plate 297 and the moving plate 333 when the door 295 is located at the open position.

In a situation such as a building where the door frame 231 is installed at a high opening, the positioning member 533 cannot be engaged with the rail 237 even at the first position due to a large distance between the door closing positioning mechanism 492 and the rail frame 235, in such a state, one or more tabs 294 may be selectively disposed between the second pivot mechanism 378 and the seat 277, the volume of the at least one tab 294 is slightly smaller than the engaging hole 293 of the seat 277, the number of the tabs 294 is determined according to the distance between the positioning member 533 and the rail 237, as shown in fig. 12A, in detail, the required number of the tabs 294 are received in the engaging hole 293 of the seat 277, so that the engaging section 397 of the second pivot 395 abuts against the tabs 294 to cushion the pivoting of the second pivot mechanism 378, and the entire door 295, the first pivot mechanism 337, and the door closing positioning mechanism 492 are pivoted together, And the roller mechanism 439 are all elevated together, and the positioning member 533 of the door closing positioning mechanism 492 can approach the rail frame 235, so that the positioning member 533 is fitted to the rail 237 of the rail frame 235 in the first position.

The pivot connection between the door 295 and the door frame 231 is mainly formed by the first pivot 353 and the pivot hole 253 of the lateral frame mechanism 233, so that the door 295 can be quickly detached from the door frame 231 as long as the first pivot 353 is separated from the pivot hole 253. In detail, referring to fig. 7, when the door 295 is in the closed position, the limit groove 319 of the pivoting outer frame 313 is shielded by the pivoting side frame 257 to prevent the connecting pin 373 from being touched, and therefore a tool cannot be used to move the first pivot 353 of the first pivoting mechanism 337 from the extended position to the retracted position, so that the door 295 cannot be easily detached when the door 295 is in the closed position, and the overall anti-theft effect of the door device 11 is further improved.

When the door 295 is in the open position shown in fig. 13 and 13A, the retaining slot 319 and the connecting pin 373 are exposed (not hidden by the pivotal side frame 257), and thus can be detachably engaged with the pushing hole 375 by using a tool, and further, the tool can be used to push the first pivot 353 from the extended position (shown in fig. 11) engaged with the pivot hole 253 to the retracted position (shown in fig. 14) disengaged from the pivot hole 253, and further, the door 295 can be tilted along the track 237 (shown in fig. 15 and 16) to cause the roller 475 of the roller mechanism 439 and the positioning member 533 of the closed-door positioning mechanism 492 to disengage from the track 237, and finally, the door 295 can be lifted to separate the engaging section 397 of the second pivot 395 of the second pivot 378 from the engaging hole 293 of the seat 277, so that the door can be quickly separated from the door frame 231.

On the other hand, to pivot the separated door 295 to the door frame 231, the pivoting plate 297 and the moving plate 333 are pivoted at an acute angle and a tool is used to move the first pivot 353 to the retracted position, further tilt the door 295 and engage the engaging end 397 of the second pivot 395 of the second pivoting mechanism 378 with the engaging hole 293 of the seat 277, then the door 295 is centered until the first pivot 353 of the first pivoting mechanism 337 is aligned with the pivot hole 253 of the track frame 235 and the roller 475 is received in the track 237 of the track frame 235, further the positioning member 533 is engaged with the track 237, and finally the first pivot 353 is released, the spring 377 biases the first pivot 353 to return to the extended position and the pivoting section 355 is engaged with the pivot hole 253 of the track frame 235, and the door 295 is pivoted inside the door frame 231 and is pivotable between the open position and the closed position (as shown in fig. 6 and 13).

The first pivot 353 of the first pivot mechanism 337 capable of moving between the extended and retracted positions is detachably pivotally connected to the pivot hole 253 of the transverse frame mechanism 233 in cooperation with the second pivot mechanism 378 and the seat 277, so as to achieve the effect of easily and rapidly detaching or installing the door 295.

The position of the limiting slot 319 of the pivoting frame 313 of the door 295 is located on the end surface between two side surfaces of the pivoting frame 313 (preferably at the center of the end surface 313B), so that when the door 295 is located at the closed position, the limiting slot 319 is shielded by the pivoting side frame 257, and only when the door 295 is located at the open position, the door can be exposed, and further, the door 295 can be detached from the door frame 231 by using a tool to link the first pivot 353, thereby providing the advantages of good detachment of the door 295 but also good anti-theft effect, and the good detachment of the door 295 facilitates the maintenance, repair or replacement of the door 295.

In addition, since the stopper groove 319 is located on one end surface 313B between two side surfaces 313A of the pivot frame 313 and is close to the first end 315, it is possible to allow the door apparatus 11 to be installed as a left-hand door or a right-hand door without replacing the pivot frame 313, which can reduce the cost of stocked parts for a manufacturer and the manufacturing cost.

The door closing positioning mechanism 492 provides a mechanism for positioning the door 295 in the closed position even when the latch 68 is in the unlatched position when the door 295 is in the closed position, thereby improving the usability and convenience of the door apparatus 11.

The second pivot mechanism 378 supports the weight of the door 295 with the bearing piece 413 by the second pivot 395 abutting against the bearing piece 413, so as to reduce the possibility of damage to the second pivot mechanism 378.

Furthermore, the second pivot 395 of the second pivot mechanism 378 is located between the bearing piece 413 and the receiving portion 291 of the bearing seat 277, and the bearing piece 413 is accommodated in the accommodating space 391 of the shaft sleeve 379, so that substances such as water or dust which may cause the bearing piece 413 to operate unsmoothly are not easy to reach the position of the bearing piece 413 from the accommodating space 391 of the shaft sleeve 379 upward beyond the second pivot 395, thereby increasing the durability of the bearing piece 413.

The roller mechanism 439 is provided with two collars 491 made of soft material to help the roller 475 roll in the track 237, so that the rolling noise can be reduced and the roller 475 can roll more smoothly.

The tab 294 may be added between the second pivot mechanism 378 and the seat 277 according to the situation of the installation site, so as to quickly fine-adjust the height of the door 295, further resulting in that the positioning member 533 of the door closing positioning mechanism 492 is located at the correct position, and the positioning member 533 can be engaged with the track 237 in the state that the door 295 is located at the closed position, so that the tab 294 is beneficial to quick installation and adjustment of the door 295.

Having thus described the basic teachings of the present invention, many extensions and variations will be apparent to those of ordinary skill in the art. For example, the door 295 may be in the form of a single piece without a folding function, in which case the door 295 may not include the roller mechanism 439 and the door closing positioning mechanism 492. Alternatively, the engaging section 397 of the second pivot 395 of the second pivot mechanism 378 and the engaging hole 293 of the seat 277 can be circular, which does not adversely affect the operation of the second pivot mechanism 378. In addition, the roller 475 may include only one groove 473 and one collar 491.

As the invention disclosed in the specification may be embodied in other specific forms without departing from the spirit or general characteristics thereof, and some of these specific forms have been indicated, the embodiments disclosed in the specification should be considered as illustrative and not restrictive. The scope of the invention is indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are intended to be embraced therein.
