Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a net member tensioning device used for partitions and desktop panels.

[0002]

2. Description of the Related Art Conventionally, in order to stretch a net member such as cloth, cloth or net, a groove is provided around a rectangular annular frame body as represented by a screen door, and the net is placed on the groove. It is well known that a member is placed and then a pressing rubber (beat) is fitted into the groove from above to fix the peripheral edge portion of the net member in the groove by the pressing rubber. In addition, a method is also known in which a bag binding portion is provided in advance at the edge of the net, and the bag binding portion is pulled by a rod-like member to apply uniform tension and stretched on the frame.

[0003]

However, in the above-described method, it is quite difficult to stretch the net member uniformly, and the stitches of the stretched net member may become uneven. Further, in such a case, it is difficult to partially adjust the tension and repair the net member while the net member is still stretched, and the net member may eventually have to be re-stretched from the beginning.

In addition, when the frame member is twisted or bent to be deformed by applying tension to the net member, the net member may not be stretched in the same plane.

In order to solve the above problems, the present invention provides a net member tensioning method and a net member tensioning device capable of uniformly tensioning a net member by a simple method to make the appearance favorable. Is the main purpose.

[0006]

That is, a method for tensioning a net member according to the present invention is a method for sandwiching a net member such as cloth or cloth between a pair of superposed frames and tensioning the net member. While the overlapping frame bodies are partially tightened by a plurality of fasteners and inseparably coupled,
With one fastener removed or loosened, the net member in the vicinity of the fastener is pushed and pulled to adjust the tension.

[0007] With such a structure, the net member can be stretched by simply overlapping the frame members with the net member interposed therebetween, so that the work is extremely simple. Also, if the tension is partially uneven and uneven stitches occur, it corresponds to the uneven tension of the multiple fasteners that tighten the frame at multiple locations. It is possible to remove or loosen one of the fasteners and adjust the tension of the net member at that portion, so that it is very easy to adjust the tension of the partial net member without affecting other portions. it can.

A method of sandwiching a net member between a pair of annular frame members having a short side and a long side and tensioning the net member after applying a tension not to loosen in the direction of the short side. With the net member tensioning method in which a tension is applied in the long side direction to adjust the tension, a large tension can be applied in the long side direction, so that the bending strength of the frame is not affected. Net members with a large span can be stretched.

On the other hand, the net member tensioning device according to the present invention includes a pair of frame bodies each having a mating surface substantially orthogonal to the stacking direction, and the stacking surfaces can be stacked with the mating surfaces facing each other. A net member sandwiched only between the mating surfaces and provided in tension, wherein one frame body is provided with a convex portion projecting from the mating surface, while the other frame body is fitted to the convex portion. It is characterized in that a concave portion which is possible and is depressed from the mating surface is provided, and the concave portion and the convex portion are fitted with the net member interposed therebetween.

With such a structure, the net member can be stretched by just overlapping the frame members with the net member sandwiched therebetween, so that the frame member can be assembled by an extremely simple operation. Further, since the net member is pulled when the concave portion and the convex portion are fitted to each other, good tension can be obtained. Furthermore, since the net member is sandwiched between the mating surfaces that are substantially orthogonal to the stacking direction and are opposed to each other, position the net member in the vicinity of the middle of the thickness along the stacking direction and make it a symmetrical shape when viewed from the front and back. Easy to do. Since the front and back surfaces do not differ from each other like a screen door and the right and left hand can be symmetrical, it can be applied to, for example, a partition for partitioning a space, which is very preferable.

As a preferred embodiment for uniformly stretching the net member, the convex portion is a ridge provided along the longitudinal direction of the one frame body, and the concave portion is formed in the longitudinal direction of the other frame body. There may be a groove provided along the stacking direction. In order to position the net member in the vicinity of the middle of the thickness along the stacking direction, the back surfaces of the respective frame bodies facing each other are used as the mating surfaces, and It is desirable that the thickness dimensions along the above-mentioned overlapping direction are substantially equal to each other.

Further, in order to have a symmetrical shape when viewed from the front and back sides, it is preferable that each frame has a substantially symmetrical shape except for the concave portion and the convex portion.

Further, the net member tensioning device according to the present invention comprises a net member sandwiched between a pair of superposed frame members, and the net member is tensioned, and the frame members can be attached to or detached from each other or tightened. It is characterized in that it is partially tightened by a plurality of fasteners that can be loosened and these are inseparably connected.

With such a structure, the net member can be stretched by simply overlapping the frame members with the net member sandwiched therebetween, so that the work is extremely simple. Also, if the tension is partially uneven and uneven stitches occur, it corresponds to the uneven tension of the multiple fasteners that tighten the frame at multiple locations. Since the tension of the net member at that part can be adjusted by removing or loosening one of the fasteners, the tension of the partial net member can be adjusted very easily without affecting other parts.

As a concrete example of the fastener, one made of an elastic body is used.
An example is one in which the frame bodies that have been overlapped are sandwiched from the outside and tightened.

The member 4 is provided with fasteners 41 and 42 for connecting the frame bodies 31 and 32 to each other, and an outer frame body 5 that covers the outer sides of the frame bodies 31 and 32.

Each part will be described in detail below with reference to FIGS.

Each of the frame bodies 31 and 32 is made of resin such that the outline shapes thereof as viewed from the stacking direction L are substantially the same and the thickness dimensions along the stacking direction are substantially the same. On the back surface of each of the frames 31 and 32, a mating surface 31a which is orthogonal to the stacking direction and faces each other when stacked,
32a are formed respectively. On one frame 31,
The frame 31, protruding from the mating surfaces 31a, 32a,
A protrusion 6 is provided which is a convex portion that circulates along the extending direction of 32. In the other frame 31, 32, a groove 7 that can be fitted to the protrusion 6 is recessed from the mating surfaces 31a, 32a so as to circulate along the extending direction of the frame 31, 32. . Further, slits 33 cut in the face plate direction are also opened on the outer peripheral surfaces of the respective frame bodies 31, 32 so as to circulate, so that the respective frame bodies 31, 32 can be slightly elastically deformed in the thickness direction. Configured.

The net member 4 is made of a flexible cloth, net or the like, and the mating surface 3 of each of the frame bodies 31 and 32.
It is sandwiched between 1a and 32a and also sandwiched between the ridge 6 and the groove 7. The peripheral edge is set so as to slightly extend outward from the outer edge of each of the frames 31 and 32.

The fasteners 41 and 42 are the frame body 3 which is superposed.
Two types are provided: a side fastener 41 for sandwiching and fixing the side portions of 1, 32 from the outside, and a corner fastener 42 for also sandwiching and fixing the corner portions of the frame bodies 31, 32 from the outside. ing.

The side fastener 41 is made of a leaf spring material and is elastically deformable, and includes a central plate 411 and a pair of side plates 412 that are bent from both edges of the central plate 411 so as to be orthogonal to each other. Is formed into a channel shape.
The width dimension of the central plate 411 is approximately the same as the frame body 31,
The thickness is set to be substantially equal to the thickness dimension of the outer edge portion of the frame 32, and is attached to the frame bodies 31 and 32 from the outside so that the frame bodies 31 and 32 are sandwiched between the inner surfaces of the side plates 412. At this time, as shown in FIG. 5, the net member 4 protruding outward from the outer edges of the frame bodies 31 and 32 is also rolled in at the same time so as to be sandwiched between the outer surfaces of the frame bodies 31 and 32. Further, one side plate 412 is provided with an engagement protrusion 413 formed by being curved inwardly so as to be easily attached and detached, and is provided on the surface of one of the frame bodies 31 and 32. It is adapted to engage with the engaging recess 3b. However, the side portion fasteners 41 are attached to a plurality of positions so as to be separated from each other on each side of the frame bodies 31 and 32 that are overlapped. In this embodiment, the mounting position is not limited, and the mounting position can be any position.

The corner fastener 42 is in the form of a channel that opens inwardly, and is used to fasten the corners of the frame bodies 31 and 32 that are L-shaped in a side view and overlap each other.

The outer frame body 5 is an extruded product made of resin or aluminum material which is attached so as to cover the peripheral portions of the frame bodies 31 and 32 superposed by the fasteners 41 and 42 from the outside. In the embodiment, the inner peripheral groove 51 is provided to cover at least the fasteners 41 and 42 to the extent that they cannot be seen.

The method of assembling the panel P having the above-mentioned structure is described below.
A detailed description will be given below together with the explanation of the method for tensioning the net member 4.

First, as shown in FIGS. 2 and 3, the frame body 31 and the frame body 32 are overlapped with each other so that the peripheral edge portion of the net member 4 is sandwiched between the mating surfaces 31a and 32a, and the ridge 6 is formed. The groove 7 is fitted. And the fasteners 41, 4
2 is sequentially inserted into the frame bodies 31 and 32 that are intermittently overlapped from the outside, and the frame bodies 31 and 32 are inseparably coupled to each other.

In this way, the peripheral portion of the net member 4 is held by the frame members 31 and 32, and the net member 4 is stretched.

On the other hand, with respect to the part where the slack is partially generated or the stitches are not uniform, the adjustment is performed as follows.

First, the fasteners 41, 4 corresponding to that portion
Remove 2. Then, in the vicinity of the frame 31,
Since the connection between the 32 is loosened, the protruding net member 4 is pulled or pushed in to adjust the tension of the portion. Then, after the adjustment is completed, the fastener 41,
Install 42.

Finally, as shown in FIG. 4, the outer frame body 5 is fitted over the entire periphery of the frame bodies 31 and 32, and the assembly of the panel P is completed. Although FIG. 5 is a partial cross-sectional view of the panel P after assembly, as shown in the figure, the peripheral edge of the net member 4 does not protrude outside the outer frame body 5. For this purpose, the protruding portion may be cut off before the outer frame body 5 is covered, or the size of the net member may be set in advance.

Therefore, according to this embodiment, the frame 3
Since the net member 4 can be stretched simply by overlapping the first and the second members 32 with the net member 4 interposed therebetween, the work is extremely simple. In addition, when the tension is partially uneven and uneven stitches are generated, the tension of the plurality of fasteners 41 and 42 that fastens the frame bodies 31 and 32 at a plurality of locations is reduced. Since one fastener 41, 42 corresponding to the non-uniform portion can be removed to adjust the tension of the net member 4 at that portion, the partial net can be very easily performed without affecting other portions. The tension of the member 4 can be adjusted.

Further, in this embodiment, each frame 31, 32 is
Has a substantially symmetrical shape except for the protrusion 6, the groove 7, and the engaging concave portion 3b, and the net member 4 is located at the center in the thickness direction and has a symmetrical shape on the front and back sides of the panel P. Will be things.

The present invention is not limited to the above embodiment.

For example, when the fasteners 41 and 42 are sequentially attached, the fasteners 41 and 42 may be attached while adjusting the tension in the attaching portion. Further, the fasteners 41, 42 may be capable of adjusting the tension by pushing and pulling the net member 4 even in the attached state, and may have a fastening force enough to maintain the state if an external force is not applied. If this is the case, panel P
The tension can be easily adjusted even when the is attached to the table that is the support body.

More preferably, the net member 4 is sandwiched between the frame members 31 and 32 in a state in which a tension is applied to the direction of the short side so as not to loosen, and at least the long side portions of the frame members 31 and 32 are fastened together. After tightening with 41 and 42, it is preferable that the tension is adjusted by adjusting only the tension in the long side direction from the short side portion, and the short side portion is fastened with the fasteners 41 and 42. This is because when the tension in the short side direction is adjusted, there is a possibility that unexpected deformation occurs in the long side portions of the frame bodies 31 and 32. Also, in actual assembly, there is a problem in adjusting only the tension in the long side direction. This is because the net member 4 can be stretched uniformly.

Further, the fastener may have a structure in which the frame bodies are fastened together by using screws, such as a clamp. Further, if it is possible to loosen in this way, the partial tension adjustment can be performed only by loosening the fastener without removing the fastener as in the above-described embodiment.

The ridges and grooves do not have to be wound, and may be discontinuous, such as dots, as long as the net member can be stretched uniformly.

The frame body is not limited to the rectangular ring shape, and may have a different shape with curved sides. Further, it is desirable that this is a closed annular shape, but in some cases, the present invention can be applied even if it has a shape that is partially closed and not closed.

Of course, this net member adjusting device can be applied not only to the panel but also to a member for tensioning the net member on the frame without loosening, such as a partition or a curtain plate, to achieve the same effect. Needless to say.

Others The present invention is not limited to the above illustrated examples,
It goes without saying that various modifications can be made without departing from the spirit of the invention.

[0042]

As described above in detail, according to the present invention, the net member can be stretched by simply overlapping the frame members with the net member sandwiched therebetween, so that the work is extremely simple. Also, if the tension is partially uneven and uneven stitches occur, it corresponds to the uneven tension of the multiple fasteners that tighten the frame at multiple locations. It is possible to remove or loosen one of the fasteners and adjust the tension of the net member at that portion, so that it is very easy to adjust the tension of the partial net member without affecting other portions. it can.

In addition, a method of sandwiching a net member between a pair of annular frames having a short side and a long side and tensioning the net member after applying a tension that does not loosen in the direction of the short side. With the net member tensioning method in which tension is applied in the long side direction to adjust the tension, it is possible to suppress deformation of the frame body when tensioning the net member and easily tension the net member flush. it can.
