Description

[Detailed Description of the Invention] The present invention relates to a lattice structure applied to fittings such as doors and shoji screens.

As for the lattice structure in the conventional lattice structure, one or both of the vertical lattice bars and the horizontal lattice bars are provided with a notch at their intersecting position, and one or both are fitted into the notch to form an intersecting shape. For those with a connecting structure, one of the vertical lattice bars and horizontal lattice bars is used as a threading material, and the other is cut and separated into two at the intersection, and the cut end surfaces are fixed in contact with the sides of each of the above-mentioned threading materials. There was one that had a structure in which they were connected in a cross-like manner. In addition, the horizontal beam and the vertical beam are constructed using the front material for the vertical beam and the front material for the horizontal beam that have the same cross-sectional shape, and the back material for the vertical beam and the back material for the horizontal beam that have the same cross-sectional shape, and the front material for the vertical beam There is also a lattice in which a notch for fitting the front material for the horizontal beam is provided, and a notch for fitting the front material for the vertical beam and a notch for fitting the back material for the vertical beam are provided in the front material for the horizontal beam, and these members are combined. (Utility Model Publication No. 55-170316).

However, the former structure is troublesome to process because it requires notches, and the strength of the lattice beam as a whole decreases due to the notches, and when external force is applied to the lattice structure, the notches In other words, there are drawbacks such as stress concentration at the intersections, resulting in bending and deformation, and in the case of the latter structure, one of the vertical lattice bars and horizontal lattice bars is a through piece, but the other Since it is no longer a through material, the strength of the lattice structure as a whole is inferior, and there are also drawbacks such as bending and deformation due to external force. Furthermore, in the lattice described in Utility Model Application Publication No. 55-170316, the front members for the vertical bars and the front members for the horizontal bars have the same cross-sectional shape obtained by extrusion molding, but each of the front members has a shape. It is necessary to process different fitting notches, which takes time and effort, and
This lattice has a structure in which the back material for the horizontal bars is cut and separated at the intersection, rather than through the through material, and this combined with the presence of fitting notches in the front material reduces the strength of the lattice. There's a problem. Furthermore, the shape of the fitting notch for the front material for the vertical beam and the front material for the horizontal beam are different, and the dimensions of the back material for the vertical beam and the back material for the horizontal beam are also different, so these components must be used separately during assembly. However, there was a drawback that the work of assembling the lattice was complicated.

The present invention was devised in view of the above points, and an object of the present invention is to provide a lattice structure that is easy to manufacture and has high strength.

That is, the present invention constructs the lattice body 10 by assembling a plurality of vertical lattice bars 1 and horizontal lattice bars 5 having the engaging recesses 4 in a cross shape with their side surfaces 8 and 9 in contact with each other. Peripheral frames 13 are provided on the top, bottom, left and right, and vertical lattice bars 1
Vertical lattice bar portion 1 that is a non-contact portion with horizontal lattice bar 5
a and the horizontal lattice bar portion 5a which is the non-contact portion with the vertical lattice bar 1 of the horizontal lattice bar 5, each side surface 8, 9 on the contact surface side
The vertical lattice cover material 15 and the horizontal lattice cover material 16 having engaging protrusions 17 are engaged with the engaging recesses 4 of the vertical lattice bar portions 1a and the horizontal lattice bar portions 5a so as to cover the vertical lattice cover members 15 and 16, respectively. The gist is a lattice assembly structure characterized in that the vertical lattice bars 1 and the horizontal lattice bars 5 are attached together, and a peripheral frame 13 is connected and fixed to the ends of the vertical lattice bars 1 and the horizontal lattice bars 5 by means of fixing fittings 20.

Embodiments of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a vertical lattice bar. The vertical lattice bar 1 is made of an extruded material of aluminum or aluminum alloy, and is configured as a hollow body. Engagement recesses 4 are formed in the first side surface 2 and the second side surface 3. 8 indicates the third side surface of the vertical lattice bar. 5 is a horizontal lattice bar made of the same material as the vertical lattice bar 1 and configured in the same shape and structure;
Similarly, engagement recesses 4 are formed on the first side surface 6 and the second side surface 7. 9 indicates the third side surface of the horizontal lattice bar.
A lattice body 10 is constructed by assembling a plurality of the vertical lattice bars 1 and horizontal lattice bars 5 in a cross shape with their third sides 8 and 9 in contact with each other. At the top, bottom, left and right of the grid body 10,
The upper frame 11, for example, a lower frame (not shown) having a shape that is vertically symmetrical or substantially symmetrical to the upper frame 11, and a left vertical frame 1.
2. For example, a surrounding frame 13 consisting of a right vertical frame (not shown) having a shape laterally symmetrical or substantially symmetrical to the left vertical frame 12 is provided. The surrounding frame 13 can be used as a picture frame or a door frame.
It may also be a fittings frame such as a shoji frame. When the surrounding frame 13 is a picture frame, fitting frames such as door frames and shoji frames are further attached to the four circumferences of the surrounding frame to form a door, shoji, etc., and the surrounding frame 13 is a door frame, a shoji frame, etc. In this case, the door, shoji, etc. will be configured as is.

Thus, a lattice assembly structure having a large number of squares is constructed, and a vertical lattice cover material and a horizontal lattice cover material are attached to the vertical grid members and horizontal grid members constituting the grid, respectively. That is, the vertical lattice bar portion 1a that is the non-contact portion of the vertical lattice bar 1 with the horizontal lattice bar 5
(The above is the grid vertical member), a vertical lattice cover material 15 is attached so as to cover the side surface 8 on the contact surface side with the horizontal lattice bars, and the part of the horizontal lattice bars 5 that is not in contact with the vertical lattice bars 1 A horizontal lattice cover material 16 is attached to the horizontal lattice bar portion 5a (the above is the grid horizontal member) so as to cover the side surface 9 on the side of the contact surface with the vertical lattice bar. Both cover materials 15 and 16 have legs, and engagement protrusions 17 are provided on the legs, and the engagement protrusions 17 are elastically pushed into the engagement recesses 4 of the vertical lattice bar portions 1a and the horizontal lattice bar portions 5a. By engaging with each other, the two are coupled and fixed.

Reference numeral 18 indicates fixing holes provided in the vertical and horizontal lattice bars, and the upper frame 1 of the surrounding frame is provided at both upper and lower ends of the vertical lattice bar 1, respectively.
1. Abut the lower frame, abut the left and right vertical frames of the surrounding frame on both left and right ends of the horizontal lattice beam 5, respectively, and insert screws, etc., through the fixing fitting insertion holes 19 provided in each frame of the surrounding frame. The fixing fittings 20 are inserted into the fixing holes 18 of the vertical and horizontal lattice bars, thereby connecting and fixing the surrounding frame to the ends of the vertical and horizontal lattice bars.

The lattice structure of the present invention is applied to fittings such as doors and entrance shoji screens.

Although the embodiment of the present invention is constructed as described above, unless it goes against the gist of the present invention, the engaging recesses, vertical lattice bars,
The specific shapes, structures, materials, and connection relationships thereof of the horizontal lattice bars, lattice bodies, surrounding frames, engaging protrusions, vertical lattice cover materials, horizontal lattice cover materials, fixing fittings, etc. can be modified in various ways.

Since the present invention does not require any notches at the intersections of the vertical lattice bars and the horizontal lattice bars, there is no need for conventional notch processing, and manufacturing is easy. In manufacturing the vertical and horizontal lattice cover materials, only a simple flat cutting process is required, so the process is much easier than the conventional notch process. Furthermore, since the present invention does not involve cutting or separating one of the vertical and horizontal lattice bars into two at the intersection, both the vertical and horizontal lattice bars can be used as threading members, and therefore the entire lattice structure Extremely strong. Since there are no notches at the intersections of the vertical and horizontal lattice bars, stress concentration will not occur at the intersections even if an external force is applied, and there is no risk of bending or deformation. Furthermore, vertical and horizontal lattice cover materials make it possible to
The strength of the horizontal lattice beams can be reinforced, and the appearance of the intersections can be designed to be as good as the conventional one. In addition, in the lattice structure of the present invention, the vertical lattice bars and the horizontal lattice bars are configured to have exactly the same shape, and the vertical lattice cover material and the horizontal lattice cover material are also configured to have the same shape. Compared to the conventional structure in which members of different shapes are used for the horizontal lattice bars, the number of types of members constituting the lattice set structure is reduced, and the assembly work of the lattice becomes easier.
