Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to lanterns installed at venues such as cherry blossom viewing or festivals.

[Conventional technology]

The frame of a conventional paper lantern is assembled from an upper frame, a lower frame, and vertical bars, and each of these members is made of wood.
The applicant previously proposed that this be formed from an extruded section of metal, particularly aluminum alloy, or synthetic resin.

[Problems to be Solved by the Invention] As mentioned above, when forming the frame of a lantern using extruded shapes, there was a problem with the means for fixing the vertical beams to the upper frame and the lower frame. As is well known, a lantern has a large upper frame and a small lower frame, and when a vertical frame is fixed to this, the vertical frame is inclined inward as it goes downward. If the upper and lower frames are the same size, the frame and the vertical bars will intersect at right angles, and one of the frames that are fixed to each other will intersect at right angles, for example, as in the case of a sash made of extruded sections. It is sufficient to provide a screw threaded section with a circular cross section and secure it by screwing a screw into the screw threaded section from the other section, but since the vertical bars are slanted as mentioned above, sections that intersect at right angles are not suitable. There was a problem that they could not be fixed together using normal fixing means.

SUMMARY OF THE INVENTION The object of this invention is to solve the above-mentioned problems.Moreover, the fixing means for the frame and the vertical beam can be firmly fixed without being unsightly exposed on the outer peripheral surface, and the structure of the fixing means can be improved. To provide a lantern that is simple and easy to assemble and operate.

[Means for solving problems]

The lantern according to the present invention has a frame formed by an upper frame, a lower frame, and vertical bars made of extruded shapes, and the upper frame and the lower frame are formed by bending the shapes into an annular shape.
A screw threaded portion with a long hole in cross section is provided on the vertical frame, and screws are screwed into the screw threaded portion from the upper surface of the upper frame and the lower surface of the lower frame to secure the frame.

To explain in more detail, the shapes constituting the upper frame and the lower frame have a belt-shaped upright outer circumferential wall with a horizontally protruding supporting wall extending over the entire longitudinal length of the outer circumferential wall. A plurality of notches are provided at intervals, and the outer circumferential wall is bent so that the supporting wall is on the inside to form an annular shape. A screw threaded portion with a long hole-shaped cross section protrudes from the inside of the main wall along the center of the frame, and the vertical bars are arranged at predetermined intervals between the supporting walls of the upper and lower frames. At the same time,
The screws are screwed into the threaded portions of both the upper and lower support walls and fixed.

〔Example〕

As shown in FIGS. 1 and 2, a lantern according to the present invention is formed by forming a frame with an upper frame 1, a lower frame 2, and a plurality of vertical bars 3, and a transparent plate 4 is fitted between each vertical bar 3. This is what I added.

Both the upper frame 1 and the lower frame 2 have the same structure, so to explain the upper frame 1, as shown in FIG. It is made of an extruded section with a protruding support wall 6, and the support wall 6 is provided with a plurality of triangular notches 7 at predetermined intervals in the longitudinal direction, with the tops reaching the outer peripheral wall 5. Semicircular small holes 8, 8 are drilled in the middle of the opposing notch end faces of each notch 7, and the outer circumferential wall 5 of this profile is bent so that the support wall 6 is on the inside.
By bending, both notch end surfaces of the notch 7 are brought into contact with each other to form an annular shape, and since the one shown in FIG. 1 is hexagonal, it corresponds to each notch 7 provided with the required number of outer peripheral walls 5. The shape is bent at each position, and the ends of the material are brought together to form a ring.The shape of the ring can be hexagonal, rectangular or octagonal, or circular. .

The means for connecting the two ends of the above-mentioned sections abutted against each other in an annular shape are as shown in FIG.
As shown in the figure, welding means 10
It is connected by . When connected in this way in an annular manner, the left and right small holes 8, 8 drilled in the notch 7 align with each other to form a circular small hole, and a screw 11 is connected to the vertical bar 3 as shown in FIG. It is intended to be inserted through the Furthermore, the support wall 6 has several through holes 1 through which a hanging string 13 can be passed and tied, or a hook (not shown) provided at the tip of the hanging string 13 can be hooked thereto.
2 is drilled.

Next, as shown in FIGS. 2 and 6, the main wall 14 of the vertical frame 3 is a strip plate, and the main wall 14 is bent depending on the shape of the upper frame 1 and the lower frame 2, that is, square or round. If it is square, it is bent into a mountain shape along the center of the width direction of the main wall 14, as shown in the figure, and if it is round, it is curved into an arc, and both sides of this main wall 14 are bent. It supports the transparent plate 4 on the main wall 14.
From the inner surface of the main wall 14 along the center of the width direction,
It has a protruding screw thread part 15 whose cross section is elongated, and is formed into a U-shape as shown in Figure 6, or an oval shape as shown in Figure 7. be. Further, this vertical beam 3 is provided with means for supporting the light-transmitting plate 4, and clamping pieces 16, 16 are provided on both sides of the inner surface of the main wall 14, respectively.

Therefore, the means for fixing the vertical beam 3 to the upper frame 1 and the lower frame 2 described above is as shown in FIGS. 1 and 2. A plurality of vertical bars 3 are fitted at equal intervals between the frames 6 and 6, but in the case of a rectangular frame, they are fitted at each corner and in such a way that the screw threaded strips 15 face the matching small holes 8, 8. The screws 11 passed through the small holes 8, 8 are vertically screwed into the screw threaded portions 15 and fixed.

In addition, as another means for connecting both ends of the sections forming the upper frame 1 and the lower frame 2, as shown in FIG. Screw-threaded strips 17, 17 with a round cross section are provided, and both ends of the support wall 6, where both ends of the upper frame 1 are butted together, are screwed together with small screws 18, 18.
It sticks to 7. In this case, the small screw 18 may be short, so it may be screwed diagonally parallel to the slope of the vertical beam 3. In addition, the round screw thread part 1
7 and 17 may be screw threaded portions 17a and 17a having an elongated cross section as shown in FIG. 9, so that the small screw 18 can be screwed in vertically. The transparent plate 4 is

〔Effect of the invention〕

The lantern according to the present invention has an annular upper frame, an outer circumferential wall that stands up on the lower frame, and a support wall that projects horizontally inward, and a vertical beam that connects the upper and lower frames is provided with a transparent plate. It is equipped with a supporting main wall and a screw threaded part with a long hole in cross section that protrudes from the inner surface of the main wall. (a) When the screw is screwed into the screw thread, the screw thread is formed into a long hole in cross section; Even if a screw is screwed vertically into an inclined vertical bar, the tip of the screw will not be exposed to the outside beyond the threaded part of the screw, and the entire length of the screw will be screwed. The threaded portion increases the area of connection of the vertical beam to the support wall, and together with this, it is possible to firmly fix the upper frame and the lower frame.

(b) Since the vertical beams are fixed to the upper frame and lower frame using screws, the assembly operation is facilitated.

(c) Also, since the screws are screwed in vertically from the top and bottom support walls of the top and bottom frames, the fixing means can be seen from the top and bottom of the lantern, but it is almost invisible from the outside. Furthermore, since the fixing means is not exposed in an unsightly slanted state, the appearance can be further improved.
