Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connection/fixing device for screen material, and relates to a connection/fixing device for screen material, and relates to a screen material that is hung in a hanging manner as a curtain, blind, tapestry, or screen through suspension means, winding means, etc. This invention relates to an improved connection/fixing tool for fixing parts and connecting them to each other.

Conventionally, this type of screen material used for partitioning or shielding is stretched in a hanging manner, so that an appropriate load is applied to the lower end.

This can be done, for example, by a pipe or a bar, and this can be fixed to the screen material by wrapping the end of the screen material around the outer periphery of the pipe, etc., and gluing or riveting it, or by providing it on the pipe, etc. and cutting the end of the screen material. In this method, a pipe or the like was inserted into the end of the screen material, which was shaped like a tube bag. However, since all of these methods integrally fix the screen material and the pipe, etc., they require a lot of work and a high level of skill when processing the ends of the screen material, and are difficult to replace because they are not easy to replace. This was extremely inconvenient for interior remodeling and other tasks. In order to solve this problem, the applicant proposed the
A device for fixing and connecting the ends of screens etc. was proposed in Publication No. 0514.

As shown in FIG. 6, a partition wall 101' running horizontally inside the pipe material having a circular cross section forms the upper and lower partitions 1.
02, and the connecting row 03 is closed in each of the compartments 102 to form a pipe-like connecting/fixing device 100 whose overall cross section is in the shape of a round Japanese character, and a band-shaped locking plate 105 portion is fixed to the Suriken material S weave. The end of the screen material S is inserted into the compartment 102, and the locking plate 105 portion is tilted between the Homare closing wall 104 of the compartment 102 and the partition wall 101, so that it is partially taut due to the suspension load. The connecting/fixing tool 100 and the screen material S are connected by forming the screen material S into a shape. In this case, connection/fixing tool 1
The connection between 00 and the screen material S is extremely strong, and it is possible to fix them and to connect the screen materials S to each other, and it is easy to attach and detach them, resulting in excellent workability. When the screen material S is inserted through the opening 103, the screen material S is largely bent at the connecting opening 103. Therefore, if the screen material S is made of a material that is difficult to bend, there is a risk that the connection/fixation odor 100 will be inconveniently tilted and the screen material S will be damaged; , it sometimes became extremely difficult to bend the connecting port 103 at a steep angle. Not only that, but if the screen material S has some strength or weakness in bending due to contact at the edge of the connection port 103, the position of the screen material S at the connection port 103 will not be constant, especially when viewed from the side. The entire structure rotated and twisted, and the design was not clean and unsightly. Therefore, the present invention has been created in view of the above-mentioned conventional drawbacks.The present invention is divided into left and right by partition walls that are inclined with respect to the suspension direction, and the partition walls are separated from the upper and lower ends of the partition walls so that the partition walls are point-symmetrical to each other. The left and right connections are connected between the ends of the free side walls with a chevron-shaped cross section that bulge outward and the upper and lower parts of the bulkheads, with each opening opening upward and downward along the suspension direction. A locking protrusion is provided protruding inside the end of the free side wall in the opening that forms the chamber, and a rigid locking plate attached to the screen material to be suspended is inserted into the connecting chamber together with the screen material, The upper and lower greens of the locking plate are brought into contact with the inner surface of the locking protrusion and the partition wall surface, and a correction ridge is lowered on the partition wall surface, and the screen extending from the locking plate side green is fixed. By placing the screen material on the corrective ridge and allowing the screen material to come out without coming into contact with both sides of the closed opening, it is possible to fix and connect the ends of the screen material. This succeeded in preventing damage, eliminating unstable set conditions that could occur due to the characteristics of the screen material itself (bending stiffness), and stabilizing the center of gravity in the hanging direction.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Reference numeral 1 shown in the figure is a partition wall that is inclined with respect to the hanging direction along the direction of the center of gravity of the screen material S to be suspended. 2 is partitioned.

That is, the connecting chamber 2 is formed by connecting the ends of the free side wall 3, which extends from the upper and lower ends of the partition wall 1 and has a mountain-shaped cross section and extends outward from the upper and lower ends of the partition wall 1, and the upper and lower ends of the partition wall 1 so as to be point symmetrical to each other. The space is formed with respective closures 4 that are open upwardly and downwardly along the suspension direction, and the entire structure is made of a rigid metal such as aluminum or a synthetic resin such as hard vinyl chloride resin. Basically, it is formed to have a substantially N-shaped cross section. At this time, the free side wall 3 may be formed in an arc shape in cross section (see FIGS. 1 to 3 and 5), or may be formed in a shape (see FIG. 4). According to the former, the overall shape has an appearance of a substantially circular pipe with a closing opening 4, and according to the latter, it has an appearance of an approximately rectangular pipe with a closing opening 4. In any case, the external shape of the connecting chamber 2 is such that the connecting chamber 2 has an internal shape such that when the locking plate 6 is inserted as described later, the locking plate 6 is in a tension-like locking state within the connecting chamber 2. By the way,
It can be of any shape. In addition, a locking protrusion 5 having a substantially ridge-shaped cross section is provided on the inside of the end of the free side wall 3 of the closing port 4, and is provided on the locking plate 6 inserted into the connecting chamber 2. The protrusions are deep enough to hold the green or lower green.

Then, the rigid locking plate 6 attached to the screen material S to be suspended is inserted into the connection chamber 2 together with the screen material S, and the upper and lower sides of the locking plate 6 are attached to the inner surface of the locking protrusion 5 and the partition wall 1. It is designed so that the edges are brought into contact and locked.

As shown in the figure, this is done by comparing the width of the locking plate 6 attached to the screen material S to the depth in the suspension direction of the connecting chamber 2 in the cross section, and also by comparing it to the maximum width. The locking plate 6 is formed to be large in size, and even if the locking plate 6 itself can swing slightly within the connection chamber 2, it cannot rotate freely. At the same time, the screen material S taken out from the connection chamber 2 is held in the locking plate 6 in a state along the hanging direction, and if the screen material S taken out upwards is placed under the locking plate 6, When the screen material S is moved downward, the upper edge of the screen material S is pulled out and stretched, so that the connecting/fixing device of the present invention and the screen material S are able to absorb the load. The traction action causes the upper and lower sides of the locking plate 6 to be pressed against the partition wall 1 and the inner surface of the locking protrusion 5. At this time, the fact that the inner surface of the free side wall 3 has a gently curved surface allows the upper or lower edge of the locking plate 6 to slide smoothly so as to be positioned on the inner surface of the locking protrusion 5. It greatly helps in exerting the locking action. Now, to explain the insertion of the locking plate 6 attached to the screen material S into the connection chamber 2, it may be slid into the connection chamber 2 from the end thereof, and in that case, A working space twice the length of the locking plate 6 is required.

Alternatively, a direct insertion means may be used in which the lower edge or upper edge of the locking plate 6 is aligned with the gate 4 and moved along the depth direction of the connection chamber 2. In that case, the connection according to the present invention may be used.・It is sufficient to have a work space that corresponds to the length of the fixed odor or the width of the screen material S, and unlike the above,
In order to form a guide for guiding the insertion of the slide, there is no need to perform cutting or the like on the end of the connecting chamber 2 so that the width becomes wider as it approaches the end, thereby simplifying the structure. On the other hand, when the connecting/fixing device of the present invention is installed and set in a bare nude style as shown in FIGS. 1, 2, 4, and 5, Either of the wrapping styles in which the screen material S is covered with the end portions can be selected.

In the former case, it is sufficient to attach one locking plate 6 to the end of the screen material S, and in the latter case, the end portion of the screen material S is made into a covering piece SI of a predetermined length, A pair of locking plates 6 are attached and fixed to the base of the free edge and the opposite side of the covering piece SI, and the end portion of the screen material S bent at the locking plate 6 portion is fixed. Insert the locking plate 6 into the connection chamber 2 together with the locking plate 6, hit the upper and lower sides of the locking plate 6 against the inner surface of the locking protrusion 5 and the partition wall 1, and then fold it back at the locking plate 6. It is sufficient to cover the outer surface of the free side wall 3 with the covered piece SI so that its surface faces outward, and fix it as appropriate. In addition, a correction ridge 7 is provided on one side of the partition wall.
, and the screen material S stretched from the green side of the locking plate 6
is brought into contact with the correction ridge 7 so that the screen material S can be taken out without coming into contact with both sides of the closing opening 4.

The surface of this correction ridge 7 has an arcuate surface, and as shown in FIG.
As shown in FIG. 3, when the overall cross-sectional shape of the connected/fixed odor of the present invention is similar to a round shape, a bulge is provided at approximately the center of the partition wall 1, and as shown in FIG. If the shape is a rectangle similar to a square, the partition wall 1 is raised approximately in the center, and as shown in FIG. 1 closing 4
It is moved sideways and lowered to the symmetrical site. In addition, the reference numeral J in the figure is a lotus hanging tool for suspending the screen material S from an appropriate position, and the locking projection 1 locks on the inner surface of the locking projection 5.
1, a connecting plate 12 is formed which is folded in two, and at the end of this connecting plate 12, a hooking plate 13 having a substantially C-shaped front surface is provided with gates facing oppositely to each other. It is provided with a hook F and is hooked onto the hook F or the like through an opening.

The present invention is constructed as described above, and when used, it can be used for partitions, panel curtains, end lids, displays, roll screens, and other uses as shown in FIGS. 1 and 2. Appropriate weight should be applied to the end of the screen material S, which is suspended via a hanging mechanism J or, for example, by a winding mechanism R having a built-in spring as shown in Fig. 3. Furthermore, as shown in FIG.
This is inserted into the connection chamber 2 together with the rigid locking plate 6 attached to the screen material S, and the locking plate 6 is held in a tensioned manner within the connection chamber 2, thereby fixing and connecting the screen material S. .

Thereafter, both ends of the connecting chamber 2 are closed with sealing lids made of rubber, synthetic resin, or other materials to prevent the locking plate 6 from sliding and coming out. Therefore, the rigid locking plate 6 attached to the end of the screen material S forms a core connecting means, and this 6 is attached to the inner surface of the locking protrusion 5 and the partition wall 1 inside the connecting chamber 2 on both the upper and lower sides. Since the screen material S is abutted and locked, it is easy to insert and lock the screen material S into the connecting chamber 2, and it is extremely easy to not only fix the end of the screen material S but also connect a large number of screen materials S. In this way, various tensioning conditions can be achieved.

In particular, the connecting chamber 2 is partitioned left and right by the partition wall 1 that is inclined with respect to the suspension direction, and has a cross-sectional mountain that bulges outward and extends from the upper and lower ends of the partition wall 1 so as to be point symmetrical to each other. It has a free side wall 3 having a shape, and a gate 4 is formed between the end of the free side wall 3 and the upper and lower ends of the partition wall 1 and is open upwardly and downwardly along the suspension direction. in,
The screen material S is taken out in a hanging direction along the partition wall 1,
Coupled with the fact that the exit part of Sekiguchi 4 is not bent, the screen material S has no scales or deviation due to its own bending stiffness, and can be connected and fixed with good appearance. It can be a state.

Therefore, damage accidents such as cracking and cutting of the screen material S that conventionally occurred due to these can be prevented, and even if the screen material S is made of a hard material, it can be used, and long-term use can be ensured. Furthermore, a correction ridge 7 is provided on one side of the partition wall, and the screen material S extended from the six locking plates is supported by the correction ridge 7, so that the screen material S opens □4.
Because it is designed so that you can go out without touching both sides,
During use, even if the screen material S has some strength or weakness in bending, it can be moved out from a certain position of the opening □4, and
It is possible to prevent rotational twisting of the entire structure when viewed from the side, and to ensure stability in use mainly from a design standpoint.

In addition, since the overall shape is a point-symmetrical structure having a partition wall 1 and a free side wall 3 with a mountain-shaped cross section bulging outward, the connecting/fixing device of the present invention when in a connected state. The center of gravity is located in the hanging direction of the screen material S,
It is always in a stable tensioned state.

Furthermore, a locking protrusion 5 protruding from the inner side of the end of the free end wall 3 at the entrance 4 prevents the locking plate 6 that is abutted against the inner surface of the 5 and locked from coming out of the connection chamber 2. It is very effective in stopping.

In addition, since the suspension load of the connecting/fixing device itself of the present invention is applied to the locking plate 6 which abuts and locks its upper and lower sides against the inner surface of the locking protrusion 5 and the partition wall 1, the connection The locking plate 6 in the chamber 2 has a tensioned shape, and this is combined with the fact that the locking plate 6 is rigid, so that the locking plate 6 is firmly engaged in the connecting chamber 2. Moreover, at this time, the locking plate 6 is locked to the inner surface of the locking protrusion 5 without the locking plate 6 itself being rotated within the connection chamber 2, and the locking plate 6 is not displaced from the abutment locking position. The connection stability is extremely high without causing any problems. Furthermore, the screen material S has a rigid attachment portion due to the attached locking plate 6, and it is easy to connect it within the connection chamber 2, as well as to remove and replace it, making it easy to handle. In addition, the connecting and fixing odor of the present invention can be mass-produced by extrusion molding using light metals such as aluminum and thermoplastic synthetic resins, so it is inexpensive and has good dimensional stability. On the other hand, it has extremely excellent effects such as being able to suspend it with an even force.
