Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention is a set of sliding door fittings that can be utilized for a set of single or multiple sliding doors, the sliding doors being arranged along a fixed track. The present invention relates to a mounting bracket for a sliding door, which includes a sliding rolling piece and a runner, and a stopper that limits the sliding movement of the door is attached to the track. Here, the explanation will focus on a type of front-facing exterior door that closes the entire empty space (opening) from the outside, but this invention naturally applies to an inner door that closes the empty space from the inside. can also be used, in which case the various parts of the fitting can be assembled in reverse order.

[Prior Art] In existing designs of mounting brackets for sliding doors, the track on which the upper rolling piece runs consists of sections, these sections being fixed to the inner surface of the ceiling of the cavity to be closed by the door. be done. In the case of two-panel doors (sliding doors), two parallel sections are required, one for each door. In this traditional construction, the door is suspended from a section that must hold the entire weight of the door. As a result of use, the screws or devices used to attach the sections may become loosened, causing the horizontal mating sections to malfunction and malfunction, eventually causing the door to squeak or catch. Or,
Or, noise may be generated during sliding. Additionally, section and door installation can be complex. [Problem to be Solved by the Invention] It is an object of the present invention to design a mounting hardware element and a mounting hardware that facilitates the installation of a door. Another object of the invention is to devise a fitting which provides a smooth and quiet sliding action and which is free from the risk of misalignment or misalignment of the elements, thus ensuring complete and reliable functioning of the entire assembly. That's true.

The invention furthermore provides a front view of the void where the door is to be closed.
Enables doors to be installed to completely cover a room or area from floor to ceiling, thereby giving said area a good finish and appearance. Although these fittings can be used with single-panel doors, their construction and operational safety make them particularly suitable for use with sets of two or more sliding doors. [Means for Solving the Problem] In the present invention, the track on which the rolling piece and the runner run, in the case of one sliding door, consists of a single upper rail and a single lower guide, In the case of two or more sliding door panels, it consists of two upper rails, parallel and close to each other, and two lower guides, also parallel and close to each other. In both cases, the rails and guides are arranged respectively on the outer surface of the ceiling and on the bottom of the cavity to be closed. External (outer) rails and outer guides are located proximate the edges of the surface. The stop that limits the sliding movement of the door is composed of an anchor foot, a vertical plate, and an angular joint plate. The anchor foot is adjacent to the rail and guide,
It is attached to the outside surface of the ceiling and bottom. The position of the upright plate can be adjusted parallel to the rail and guide and is attached to the anchor foot. Its vertical end houses a mechanism for holding the rolling pieces and stopping the runner. The angle joint plate serves as a base for the screws that attach the plate to the anchor foot.

The upper rolling piece consists of a pulley wheel having a groove around its outer end, which is attached by bearings to the shaft, which is an integral piece parallel to and adjacent to said pulley wheel. This plate is fixed directly to the inner surface of the door closest to the cavity to be closed and is adapted to support the pulley wheel on the external rail and at a position remote from the cavity to be closed. It is attached to the door by a bridge, which spans the external rail and sets the pulley wheel on an internal guide (located away from the door). The lower runner includes an anchor base, a shell whose cross section can be attached to the guide and the anchor base, and a stop that limits the opening action. The anchor base is attached directly to the inner surface of the door closest to the cavity to be closed, so that the shell can be fitted onto the outer guide and the runner shell is attached to the inner guide (from the door). Attached to the door at a distance from the void to be closed by a bridge set above the door (located at a distance). The outer rail and guide stop are set between the sections forming the upper rail and the two lower guides, while the inner rail and guide stop are set at the ends of said rail and guide. The aforementioned anchor foot of the stopper consists of an L-shaped cross-section piece, on the top of the concave surface of which a metal angle joint plate is attached. On the outer surface of one of its legs, this piece is provided with a set of transverse teeth or a pair of teeth. The vertical (upright) plate of the stop includes a lower section, one of whose faces is provided with a set of vertical teeth or saw teeth, and an upper section with opposing notches at the vertical end includes a rolling section. A mechanism is provided to hold the pieces. The plate and anchor foot are attached by screws inserted into threaded holes in the angle joint plate, and teeth on the vertical plate engage teeth on the anchor foot. The relative position between the two pieces is adjustable by means of the teeth.

A part of the axis of one of the upper pulley wheels of each door protrudes from the free surface of the wheel and faces the notch of the vertical stopper plate, so that when the door is fully opened or closed, the pulley The protruding portion of the wheel rest axle enters a notch and is rested on the back of the pulley wheel retaining mechanism, where it is locked in place, freeing the protruding portion of the axle to initiate the sliding movement of the door. The structure is designed to reduce the pressing force required for These features, together with other features of the invention, will be explained in detail below with reference to the drawings, which show an example of an application of the invention.

Embodiment In the illustrated embodiment, two doors, designated 1 and 2, are provided. Figures 1 and 2 show the upper mechanism of the mounting bracket. This mechanism includes a rolling piece, which is composed of a bobbin ring 3 having a groove around its outer end. Each wheel is attached to the support plate 4 as described below. The two wheels 3 are attached to the inner door 2 via the plate 4.
It is fixed directly to the back of the Two further pulley wheels 3 are mounted by bridges 5 on the outer door 1, which is the door furthest from the cavity (opening) to be closed.

The wheel 3 can roll on a track consisting of two rails 6, said two rails 6 being attached to the outer surface of the ceiling 7 of the cavity to be closed. These rails have an L-shaped section and are provided with flat legs 8 with drilled holes for set screws 9. The other leg 10 of this section is thick-walled and has a round cross-sectional shape, the radius of which is approximately equal to or slightly smaller than the radius of the groove of the pulley wheel 3. Furthermore, the legs 10 are provided with channels 11 starting at the outer surface of the legs 8 in these sections 6;
A core is inserted here to strengthen the section and connect it to extend its length. An external (outside) rail 10 is arranged adjacent to the free end of the ceiling 7.

To limit the sliding movement of the doors 1 and 2, four stops 12 are provided, two between the rails 6 and another two immediately behind the back rail 6. As clearly shown in FIGS. 3 to 5, the pulley wheel 3 is attached to the support plate 4 by bearings 13. On the back of the plate 4 there is a knob or pivot 14.
are provided, and at different distances on both sides of the pot,
Two slots (15 and 16) are provided, which have different lengths and are curved around the pivot 14. To mount these wheels, the pivot 14 is inserted into a hole drilled in the door 2 or bridge 5. Next, plate 4 is attached using screws inserted into slots 15 and 16. The position and height of the plate can be adjusted by rotating it on the pivot 14 and by increasing the dimensions of the slots (15 and 16). Once the pulley wheel 3 is in the correct position, the mounting screw (Fig. 1) 1
7 is tightened and the plate 4 is attached to the door 2 and the bridge 5.
It is fixed to . One of the pulley wheels for each door (in some cases, bridge 5
or one of the pulley wheels 3 attached to one side of the door 2
One of the pulley wheels attached to the door) has a knob 18 as an extension of its axis, the knob 18 having the function of fixing the fully open and closed positions of the door.

The bridge 5 consists of a U-shaped curved plate and is attached to the inner surface of the door 1 by one of its side legs, and the plate 4 holding the pulley wheel 3 is attached to the other leg. As shown in Figure 2, pivot 1
9 extends from a leg attached to door 1 and is inserted into a hole drilled from the inner surface of said door, serving as a positioning element to facilitate the installation of the door. The mechanism shown in Figures 6 and 7 is provided at the bottom of the door. The mechanism includes two guides 20, which are arranged parallel and close to each other and are mounted on the underside of the bottom 21 of the cavity to be closed.
An external guide is placed adjacent the free end of the bottom 21.
These guides consist of an L-shaped section a, one leg, indicated at 22, being completely flat and the bottom section 21
and is attached thereto by screws 22 passing through holes drilled in said legs. The other leg 23 of the L-shaped section is provided with an enlargement through which a channel 25 is provided which terminates on the outer surface of the leg 22 and retains the strength and guide connection as used for the track 6. The free ends of the legs 23 in the longitudinal direction form a guide, on which the runners 26 slide. Two of these runners are mounted directly on the inner surface of the inner door 2, while two other runners are mounted on the outside by means of bridges 5 identical to those described with respect to the rolling elements in FIGS. 1 and 2. Door l
It can be attached to. As in the case of FIGS. 1 and 2, identically formed stops 12 are set between the guides and serve to limit the maximum open and closed positions. As shown in FIG. 7, the runner 26 includes an anchor base 27 and a shell 28 having a cross section that can be fitted into the legs 23 of the guide 20. One runner of each door includes a stop 29 that limits the opening and closing action of the door.
The base 27 is attached to the bridge 5 and the door 2 by screws (FIG. 7, 30), while the shell 28 is attached to the base 27.
It is slid to the upper position. The screw 30 also has the function of fixing a lower stop 29 consisting of a right-angled strip.

The housing which mounts the shell 28 on the base 27 forms flexible tabs 31, each oriented on either side and whose ends have the shape of a half-shaped arrow, as shown in FIG. When the base 27 and shell 28 are fitted together, they function as a stopper that prevents relative sliding between them. Each stop 12, as shown in FIGS. 1 and 6, consists of an anchor foot 32 which is adjacent to the track 6 and the guide 20 by means of a vertical plate 33 whose position can be adjusted to the ceiling 7 and It includes an anchor leg portion 33 that is directly attached to the outer surface of the bottom portion 21, and a connecting angle member 32a. The anchor foot 32 is constructed from an L-shaped section with legs having different lengths, as shown in FIGS. 9-11. The long leg portion 35 is provided with a hole 36 for a screw,
These screws are for attaching the legs 35 to the ceiling and the outer surface of the bottom. The other leg, designated 27, is
Two horizontal slots 39 and vertical saw teeth 3 on its outer surface
Equipped with 8. On one side of the vertical plate 33 is provided a set of serrations 40 that can engage the serrations 38 of the anchor leg 32, as shown in FIGS. 12-14. This plate further comprises two holes 41 for screws fixing itself to the anchor foot. The connecting angle 32a fits onto the concave surface of the anchor foot 32 and is provided with a threaded hole for a screw, which is inserted into the hole 39 of the anchor foot 32 and the hole 4 of the plate 33.
1 to attach these three pieces. The position of the plate 33 relative to the anchor foot 32 can be adjusted by means of a slot 39 in the anchor foot. The plates are fixedly fastened to each other by tightening the screws attaching them to the foot because of the interlocking teeth (38 and 40) on the foot and plate. As shown in FIG. 12, the plate 33 is provided with two notches 43 running from its vertical ends, which notches are defined along the top by elastically deformable pins 45; It has a diagonal bend, thereby forming an angled elbow 46, the convex side of which faces the notch 43 and is partially closed to form a mechanism for holding the upper boob wheel. The end portion 47 of the pin 45 terminates in an upward direction.

In FIG. 1, when the door (l and 2) reaches the limit of its opening and closing action, the knob 18 on the pulley wheel 3 enters the notch 43 in the counterstop 12 and is held there by the angled elbow 46. Ru. At the same time, the stopper 2
9 hits the opposite end of the plate 33, and this condition also occurs in the fully open position. The door is thus locked in its fully open or closed position. To free the door, only a small pressure is applied to the door so that the protruding part 18 of the upper wheel axle jumps over the angled elbow 46 partially closing the notch 43. is sufficient. With the arrangement described here, the doors 1 and 2 can be slid back and forth very easily by means of the upper rolling piece and the lower runner and guide. The weight of the door is held on the ceiling 7 of the void. The fully open and closed positions are completely limited by the stop 12. Since the height of the plate 4 holding the wheels 3 is adjustable, further parts can be installed together with the doors 1 and 2 very easily. Further, as shown in FIG. 7, a pair of slots (48 and 49) are provided at the upper and lower ends of the outer side of the runner shell 28, and these slots are defined by a difference in height between the wall portions 50 that define the slots. They have different depths. This means that the mouths of both channels and the ends of the walls that define them are located from the longitudinal mean plane of the runner and therefore from the shaft of the mounting screw 30.
This means that they are placed at different distances. With this construction, possible errors during installation can be accommodated by setting the runner shell 28 in the illustrated position or vice versa. As indicated at the beginning of this description, although the description of this fitting is specific to a single type of door, it can also be used for interior doors. In this case, single or multiple rails 6
is set on the lower piece on the floor, the weight of the door is held by the rolling piece 3 attached to the lower piece, and the guide 20 is attached facing the track corresponding to the upper piece to keep the weight of the door. It cooperates with a runner 26 which is attached to the upper inner piece using a base 27. Having thus fully described the nature of the invention and its embodiments, it will be obvious that various modifications may be made to the details within the scope of the basic principles of the invention.
