Abstract

PURPOSE: To simplify assembly operation by a method wherein length-breadth louver members are engaged while opposing slits, the front end sections of the slits are caulked to form a grating unit, in which a top face and an underside are formed in the same surface, and the grating unit is interlinked with the runner member of a ceiling surface. CONSTITUTION: Each lateral louver member 3' arranged at pitches L while downwards directing slits 4, 5 is crossed mutually at right angles with each longitudinal louver member 3 disposed in parallel at pitches L while upwards directing the slits 4, 5. Both end sections of the lateral louver members 3' are projected alternately in length of 2L on every other member 3', both end sections of the longitudinal louver members 3 are projected alternately in length of L, and each opposed slit 4, 5 is inserted and engaged from upper and lower sections and a grating unit 2 is formed. The grating unit 2 is placed on a runner member fixed onto a ceiling surface, and the slits 5 of the lateral louver members 3' are inserted and interlinked into the upward slits of the runner member. Accordingly, an integral ceiling grating louver, in which continuously connected sections are difficult to be discriminated, can be acquired.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling grid louver for diffusing the light of ceiling lighting.

[0002]

2. Description of the Related Art In a conventional ceiling grid louver, a plurality of runner members are fixed in parallel to a hanging fitting or the like which is hung from the ceiling surface, and the louver members are vertically and horizontally attached to the runner members. Both sides (both sides) of the assembled grid unit are locked, and they are locked while sequentially connecting them in the vertical direction, and are also sequentially locked to the runner members that are horizontally adjacent to each other in order. Had formed the whole.

However, the ceiling grids connected vertically and horizontally are
Since the bar must be formed integrally as viewed from below, the connecting portions of the respective lattice units are partially projected from each other, and they are combined with each other to be integrated. Therefore, the respective louver members forming the lattice unit have been combined by changing their respective shapes and lengths or the dimensions of the slits according to their required locations. As a result, the louver
It is necessary to prepare several kinds of members with different sizes,
In addition, since the type and left and right of each louver member are checked and the louver members are engaged in that position at that position, the machining process and the assembling process become quite complicated, and the mounting work is very limited. It was not easy for anyone except some skilled workers.

[0004]

SUMMARY OF THE INVENTION The present invention is applicable to all rules.
If the bar members have the same size and only one type is prepared, a reliable assembly can be performed without looseness in any part, and the ceiling can be easily formed by anyone without discriminating the connecting part. The purpose is a grid louver.

[0005]

In order to achieve the above object, the present invention provides a louver member in which ceiling lattice louvers are combined in a vertical and horizontal lattice pattern and both side portions of the combined louver members. A plurality of slits, each of which is composed of a runner member to be held and which is orthogonal to the longitudinal direction at one side edge of the louver member and the runner member, is provided at a pitch of a grid width L at equal intervals.
The depth of the two slits at both ends of the member and the slit of the runner member is half the width of the louver member, and the depth of the other slits of the louver member is half the width of the louver member. To the louver member which is made slightly shallower, and the distance between the slits at both ends of the louver member and the both end edges is L, the slits are directed upward, and a plurality of intervals are arranged at a pitch of L in parallel. A plurality of louver members having slits facing downward and arranged at a pitch of L in parallel are orthogonal to each other, and the end portions of the louver members having downward slits are staggered by one or more. A runner mounted on the ceiling part in parallel with the ceiling part by projecting on both sides with a length of 2 L and inserting and engaging the opposing slits and caulking the slit tips to form a lattice unit with the upper and lower surfaces on the same plane. -Rule assembled in the lattice unit in the upward slit of the member- - comprising a downward slit end said projecting on either side of the member is engaged, and the configuration.

In the present invention, the rule of the upward slit is
The bar members are assembled by alternately projecting one end or a plurality of ends at a length L, or by making the slit widths at both ends of the ruler member slightly wider than other slit widths. It becomes more suitable.

[0007]

In the ceiling lattice louver according to the present invention, most of the central portion of the lattice unit is engaged with a slit that is shallower than half the width of the louver member, so that the tip of the slit is caulked. Assemble without loosening. The pitch of each slit is equal to the grid width L, and the end portions of the louver members of the downward slits are staggered with a length of 2L alternately by projecting one or a plurality of them on both sides. -Since the members are sandwiched and engaged from both sides, it is possible to form an integral square lattice in which it is difficult to distinguish the connecting portion when viewed from below.

Further, since the depth of the upward slit of the runner member and the downward slit of both ends of the louver member engaging with the runner member are both half the width of the louver member, they are integrated without caulking. If the slit width is slightly wider than the other slit widths, it is easy to engage and disengage.

EXAMPLE An example of the present invention will now be described with reference to the drawings, but the present invention is not limited to this example. 1 and 2 are perspective views showing an assembled state of an embodiment of the present invention.

The ceiling grid louver is a ceiling lighting (not shown)
The runner member 1 fixed below the ceiling surface in parallel with a hanging metal fitting (not shown) suspended from the ceiling surface, and the lattice unit 2 engaged from above the runner member 1 for illumination light. It acts to diffuse downward. The lattice unit 2 is composed of a vertical louver member 3 and a horizontal louver member 3 ', both louver members 3, 3'are all the same size, and the runner member 1 has a width and Make the thickness the same.

Each of the louver members 3, 3'is provided with a plurality of slits 4 orthogonal to the longitudinal direction on one side edge thereof at a pitch of a lattice width L, and the depth h thereof is the louver member. Is slightly shallower than half the width of the louver member 3 and is slightly wider than the thickness of the louver member 3. The depths H of the slits 5 and 5 at both ends of both louver members 3 and 3 and the plurality of slits 5 arranged on the runner member 1 at a pitch of L have a depth H. Of the slit 4 and is slightly wider than the width of the slit 4. The louver members 3, 3 '
The distance between both ends of the slits 5 and 5 is L.

To assemble the lattice unit 2, as shown in FIG. 1, the slits 4 and 5 are formed on each of the vertical louver members 3 in which the slits 4 and 5 are arranged in an upward direction and are spaced in parallel at an L pitch.
And the horizontal louver members 3'arranged downward in parallel at an L pitch in parallel with each other, and the lateral louver members 3'alternatively alternate with each other at a length of 2L. Of the vertical louver member 3 and the opposite end portions of the vertical louver member 3 are alternately protruded by the length L, and the slits 4 and 4 face each other.
5 is inserted from above and below and engaged.

Further, vertical and horizontal louvers engaged in a grid pattern.
When the members 3 and 3'are pressed from above and below so that they are flush with each other, the slits 4 with depths h and h and h and H are
5 is in a state where its tip is crushed and "crimped",
The lattice unit 2 is formed. Here, the louver member 3,
Although the slits 5 and 5 having the depth H at the both ends of 3'cannot be "crimped", most of the central portion of the lattice unit 2 is in the "crimped" state, so that the lattice unit 2 can be securely fixed. It is fixed.

The lattice unit 2 assembled in this way
Is placed on the runner members 1, 1 fixed in parallel to a hanging metal fitting (not shown) suspended from the ceiling surface so that both sides of the runner members 1, 1 are hooked up.
In addition, the downwardly extending slits 5 at the ends of every other lateral louver member 3 ′ are alternately inserted and engaged. Here, since the slits 5 and 5 are engaged with each other at depths H and H and have a wide width, there is no "caulking" and the engagement and disengagement is easy.

Next, the grid unit 2 attached is engaged with the runner members 1 and 1 at both side portions of a new grid unit 2 vertically adjacent to each other, and the runner members 1 and 1 are sequentially connected in the vertical direction. Here, the end portions of the respective vertical louver members 3 of the respective lattice units 2 protruding by the length L are staggered alternately in the horizontal direction of the mating ruler.
Since it comes into contact with the bar member 3 ', the connecting portion becomes an integral lattice which is difficult to distinguish when viewed from below.

Further, the runner members 1, 1 which are laterally connected
In the meantime, another lattice unit 2 is attached in sequence as described above, but here, the horizontal loops on both sides of the lattice unit 2 are attached.
The end portion of the bar member 3 protruding by a dimension of 2L has a dimension L up to the runner member 1, and from there, the other vertical louver.
Since the size up to the member 3 is L, the louver member 1 is alternately sandwiched and alternately abutted against the other vertical louver member 3 for mating, so that the connecting portion is discriminated from the bottom. It becomes an integrated lattice that is difficult to do.

[0017]

According to the present invention, the present invention can be applied to all rules.
The bar members can be made the same size, and the engagement is firmly fixed by crimping the central part, so if only one type of louver member is prepared, it can be applied to any part. Assemble without loosening is possible. In addition, since the louver members have the same dimensions, the connecting portions of the adjacent lattice units are alternately combined at the same pitch including the runner members. It becomes an integrated ceiling grid louver that is difficult to do.
