Sliding curtain lower rail stabilizer

The invention relates to a sliding curtain lower rail stabilizer device, in particular to a device disposed between two adjacent lower rails, comprising a sliding member movably disposed in an axial sliding slot of a front lower rail, and a The L-shaped guiding member is fixed on the front end of the rear lower rail, and the upper protruding portion of the sliding piece can be movably sleeved in the longitudinal guiding groove of one of the L-shaped guiding members to promote the use. Operational stability and synchronism, and the overall device is not exposed without affecting the appearance.

A sliding panel is a common blind. The general structure includes a rail or a rail set with a plurality of grooves, and a plurality of carrier tracks are disposed under the rail. A plurality of panels are respectively disposed under the respective slide rails, and a plurality of lower rails are respectively disposed at the lower ends of the respective curtain panels to form a vertical weight, wherein each of the slide rails is connected by a connector provided at an upper end thereof The sliding member slides in each groove of the track, so that the sliding rails and the connected curtains and the lower rail are synchronously slided under the rail to be sequentially expanded one by one to form an unfolded state, or The merges are merged one by one in order to form a collapsed state. Wherein, when each slide rail and the connected curtain panel and the lower rail are in an unfolded state, an overlapping region is disposed or formed between the adjacent two curtains, and a common general transmission sliding panel curtain is taken as an example to illustrate the curtain. The width is 50-80 cm, and the width of the overlapping area between the adjacent two curtains is 5-10 cm, so as to avoid external light directly entering the room from the gap between the adjacent two curtains. However, there is an overlap between adjacent curtains. Therefore, there is also an overlap zone between the adjacent two lower rails, and since the curtain and the lower rail are only placed under the respective slide rails, and each of the curtains is generally composed of a soft curtain of the same predetermined height, the operation is performed piece by piece. When it is unfolded to form an unfolded state or the operation is folded one by one to form a collapsed state, the adjacent two lower rails are easily swayed to collide with each other or emit noise, and even the longitudinal edges of the adjacent two curtains are easily staggered and deformed. Or create crepe, causing troubles in use.

A related solution has been developed on the market for the problem of easy turbulence between adjacent two lower rails in a sliding curtain. These prior art techniques provide a coupling mechanism between adjacent two lower rails, but the prior art The structure of the connecting mechanism is complicated, the assembly is not easy, and it must be used together with the sliding curtain of a specific design, and cannot be easily extended to the general sliding curtain, which is relatively troublesome for the manufacturing end and the used end; and the above-mentioned conventional connecting mechanism In use, at least the following disadvantages exist: one disadvantage is that the joint mechanism is assembled and protrudes outside the end of each lower rail, and can be easily seen by the appearance of the sliding curtain when in use, especially when the folded state is formed. The connection mechanism is relatively detrimental to the aesthetic appearance of the sliding curtain; further disadvantage is that the curtains are generally composed of soft curtains of the same predetermined height, but in actual production, the total height of the curtains of the curtains and the lower rails thereof Uncontrollable to the degree of precision of complete equality, that is, there is often a reasonable tolerance range (a little drop) between the heights of adjacent two lower rails, that is, between adjacent two lower rails The high-low situation occurs, causing the connection mechanism installed between the adjacent two lower rails to also be relatively skewed or twisted, which affects the use efficiency of the conventional joint mechanism; another disadvantage is that due to the conventional connection The limitation of the mechanism design is that when the reverse is sequentially and piece by piece and merged to form a collapsed state, the overlap of the side of one side of the track (ie, the side near the window) is not good, that is, the adjacent two curtains The sheet (including the slide rails and the connected curtains and the lower rails) cannot be completely overlapped, and the fascination of the slide curtains in the collapsed state is relatively impaired, and it is difficult to meet or satisfy the requirements of the consumer.

The main purpose of the present invention is to provide a sliding curtain lower rail stabilizer device which is disposed between a front lower rail and a second lower rail of a rear lower rail, and includes: a sliding member disposed under the front lower portion One of the axial sliding grooves of the rail, and an L-shaped guiding member are disposed on the front end of the rear lower rail, and a convex portion of the sliding piece can be movably sleeved on one of the L-shaped guiding members The vertical guide groove moves up and down to improve the stability and synchronization of the sliding curtain in use and operation.

A further object of the present invention is to provide a sliding curtain lower rail stabilizer device, wherein the lower rail stabilizer includes a sliding member and an L-shaped guiding member hidden in opposite side wall surfaces of the adjacent two lower rails. Therefore, it does not protrude outside the front end or the rear end of the adjacent two lower rails, so that the function of the sliding curtain curtain is improved without affecting the aesthetic appearance thereof.

However, it is not limited to slide in the groove 11 of the rail 10 so that the slide rails 20 and their correspondingly connected curtains 30 and the lower rails 40 (40a, 40b, 40c, 40d) are synchronized in the rail 10 Parallel sliding underneath, and then sequentially unfolded toward a deployment direction (as indicated by arrow A in Figure 1-3) to form an unfolded state (as shown in Figure 1-3), or reverse (ie, toward a collapse direction) , as shown by the arrow B in FIG. 4, sequentially and collectively merge and overlap to form a collapsed state (as shown in FIG. 4-5); in addition, each of the slide rails 20 of the embodiment and the pair thereof When the joined panel 30 and the lower rail 40 (40a, 40b, 40c, 40d) are folded on one side of the rail 10 (such as the left side in FIG. 4) to form a folded state, a completely overlapping state, that is, a phase can be formed. Between the two adjacent curtains (including the respective slide rails 20 and the curtains 30 and the lower rails 40 connected thereto), the lower rails 40a, 40b, 40c, 40d as shown in FIG. 4 may completely overlap.

The lower rail stabilizer 2 of the present invention is disposed between the adjacent two lower rails 40 of the sliding curtain 1, and is illustrated by way of example, but not limited to FIG. 1, 2, and 4, and the lower rail stabilizer 2 is established. The position is included between the adjacent two lower rails 40a, 40b, or between the adjacent two lower rails 40b, 40c, or between the adjacent two lower rails 40c, 40d; the following two adjacent rails 40a, 40b are taken as an example. Illustrated, but not limited, in terms of the direction of deployment (as indicated by arrow A in Figures 1-3), since the lower rail 40a is located before the lower rail 40b, the lower rail 40a is defined as a front lower rail 40a, and The front lower rail 40a and the lower rail 40b are defined as a rear lower rail 40b; that is, in the case of the adjacent two lower rails 40b, 40c, the lower rail 40b is defined as a front lower rail 40b, and the lower rail 40c. It is defined as a rear lower rail 40c, and so on.

Referring to Figures 3, 5, 6, and 7, the lower rail stabilizer 2 mainly includes a sliding member 50 and an L-shaped guiding member 60. The sliding member 50 is slidably disposed on the front lower rail 40a. An opening faces the axial sliding groove 41 of the rear lower rail 40b, so that the sliding member 50 is slid back and forth between the front end 411 and the rear end 412 of the axial sliding groove 41, for example, in FIG. 4-5. In the collapsed state shown, the slider 50 slides and stops at the front end 411 of the axial chute 41, while in the unfolded state shown in Figures 2-3, the slider 50 slides to a stop. The axial chute 41 is at a rear end 412. In addition, the slider 50 is provided with a protrusion 51 protruding toward the rear lower rail 40b.

The L-shaped guide member 60 includes a first side portion 61 and a second side portion 62 perpendicular to the first side portion 61. The first side portion 61 is fixed to the rear lower rail 40b. The front end 411 is disposed such that the second side portion 62 extends toward the rear end 412 of the rear lower rail 40b and faces the front lower rail 40a; further, a longitudinal guide groove 63 is disposed on the second side portion 62; The protruding portion 51 of the sliding member 50 of the front lower rail 40a is movably sleeved in the longitudinal guiding groove 63 of the L-shaped guiding member 60 provided in the rear lower rail 40b, that is, the protruding portion 51 after the sleeve is completed. It is necessary to move up and down in the longitudinal guide groove 63.

In use, when each of the slide rails 20 and the attached curtain 30 and the lower rail 40 (integrally integrated) are sequentially deployed one by one to be converted and expanded by the collapsed state (as shown in FIGS. 4 and 5). When the state is as shown in FIG. 2 and FIG. 3, the sliding member 50 provided on the front lower rail 40a is slid by the axial direction. The front end 411 of the slot 41 is slidably moved to the position of the rear end 412, and is retained in the longitudinal guide groove 63 of the L-shaped guide member 60 provided by the rear lower rail 40b by the protrusion 51 of the slider 50. Between the front lower rail 40a and the rear lower rail 40b, that is, between the adjacent two lower rails 40 (40a, 40b), the connecting state is maintained, and the sliding member 50 and the L-shaped guiding member 60 are hidden. In the space between the adjacent front lower rail 40a and the rear lower rail 40b, that is, hidden between the opposite side wall surfaces of the adjacent two lower rails 40, to avoid protruding outside the front ends of the lower rails 40, The advantage of not damaging or detracting from the aesthetic appearance of the sliding curtain 1 is achieved.

In use, when the slide rails 20 and the connected curtains 30 and the lower rails 40 are integrally combined into one piece, they are sequentially folded one by one to be converted into an unfolded state (as shown in FIGS. 2 and 3). In the assembled state (as shown in FIGS. 4 and 5), the sliding member 50 provided on the front lower rail 40a is slidably moved from the rear end 412 of the axial sliding slot 41 to the front end 411 position, and is driven by the sliding member 50. The protrusion 51 is sleeved in the longitudinal guide groove 63 of the L-shaped guide 60 provided in the rear lower rail 40b, so that the front lower rail 40a and the rear lower rail 40b, that is, the adjacent two lower rails 40 The connecting state is maintained between (40a, 40b), and the sliding member 50 and the L-shaped guiding member 60 are hidden in the space between the adjacent front lower rail 40a and the rear lower rail 40b, that is, hidden. Between the opposite side wall faces of the adjacent two lower rails 40, the protrusions are prevented from being protruded outside the front ends of the lower rails 40, and the advantage of not damaging or detracting from the aesthetic appearance of the sliding sheet curtain 1 is achieved.

In addition, when the adjacent lower lower rail 40 is at a different height from the lower lower rail 40a and the rear lower rail 40b, there is often a reasonable tolerance between the front lower rail 40a and the rear lower rail 40b. The range (fall) exists because the protrusion 51 of the slider 50 provided in the front lower rail 40a can freely move up and down in the longitudinal guide groove 63 of the L-shaped guide 60 provided in the rear lower rail 40b, thereby Automatically compensating and adjusting the difference between the front lower rail 40a and the rear lower rail 40b, that is, even if a drop occurs between the adjacent lower rails 40, the slider 50 of the present invention and the L-shaped guide 60 are Compensation and adjustment functions are automatically generated to overcome the problems caused by the drop between adjacent lower rails 40.

Referring to Figures 3, 5, 6, and 7, the slider 50 has an axial length for the slider 50 to be at the front end 411 and the rear end 412 of the axial chute 41 of the front lower rail 40a. The sliding portion 51 is slidably disposed at the front end of the axial length of the slider 50, which is directed toward the unfolding direction (as indicated by an arrow A in FIGS. 1-3). In addition, when each of the slide rails 20 and the attached slats 30 and the lower rails 40 (integrally integrated) are sequentially unfolded one by one to form an unfolded state, a width is formed between the adjacent two slats 30. The overlap region, wherein the slider 50 has an axial length that can be used to match the width of the overlap region.

Referring to Figures 6 and 7, the lower rail 40 (40a, 40b, 40c, 40d) of the present invention can be formed by an aluminum extrusion process and then cut into an aluminum extruded frame to make the lower rail 40 (40a). The axial section 41 and the C-shaped groove 413 are formed in the forming section of the 40b, 40c, 40d); the first side 61 of the L-shaped guiding member 60 can be locked by a locking member 80 such as a screw. In the C-shaped groove 413 of the cross section of the rear lower rail 40b, the second side portion 62 is separated from the side wall surface of the rear lower rail 40b by a distance 414 (as shown in FIGS. 3, 5, 8). The segment distance 414 is that the protrusion 51 of the slider 50 provided on the front lower rail 40a is freely movable up and down in the longitudinal guide groove 63 when being disposed in the longitudinal guide groove 63 of the L-shaped guide member 60. (As shown in Figures 3 and 5). In addition, when the L-shaped guide 60 is fixed on one end (front end) of the lower rail 40, other fixing members 70 can be utilized at the other end (rear end) of the lower rail 40 (as shown in FIGS. Fixed) to optimize the cross section of the other end (rear end) and to prevent the slider 50 from being disengaged from the rear end 412 of the axial chute 41.
