Description

  The present invention relates to a foldable opera glass made of cardboard or the like.

  Opera glasses are used for sports watching and theater performances, and foldable cards such as cardboard are provided as the opera glasses. This type of opera glass is lightweight and small when folded, so it is convenient to carry and has the advantage of being obtained at a low price. It is also widely used as a gift or a promotional product.

  However, this conventional folding type opera glass has practical problems such as being difficult to see when the sunlight is too bright and the objective lens is easily damaged.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a foldable opera glass made of cardboard or the like that is more practical.

  In this device, a front surface portion provided with an objective lens, a rear surface portion provided with an eyepiece, an upper surface portion connecting the front surface portion and an upper portion of the rear surface portion, and a lower surface portion connecting a lower portion, the upper surface portion And an opera glass composed of a sheet body that is folded so that the front surface portion and the rear surface portion are close to each other by being bent at the lower surface portion, along the upper edge and the lower edge of the front surface portion, when in use And a pair of protrusions that are positioned so as to cover the objective lens when folded.

  The opera glass having the above configuration prevents the light from directly reaching the objective lens when used by the protrusions located at the upper edge and the lower edge of the front surface, thereby preventing the light even in an environment where sunlight is strong. You can see the object without Furthermore, when not in use, each of the protrusions covers and protects the objective lens to prevent damage.

  As the sheet body, cardboard, a plastic sheet or the like is preferably used.

  According to this device, it is possible to obtain an opera glass excellent in practicality in which an object is always easy to see and damage to the objective lens is prevented when folded.

  FIG. 1 is a front perspective view of the opera glass of the present invention, FIG. 2 is a rear perspective view thereof, FIG. 3 is a perspective view in the middle of the folding, and FIG. 4 is a perspective view in the folding state.

  The opera glass 1 is entirely made of thick paper, and includes a front surface portion 4 provided with a pair of objective lenses 2 and 2, a rear surface portion 8 provided with a pair of eyepieces 6 and 6, an upper surface portion 10, and a lower surface portion 12. And both side surface portions 14 and 14. A pair of projecting portions 15, 15 that project forward along the upper and lower edges of the front surface portion 4 are integrally provided. Bending portions 16 and 16 are provided at opposite positions substantially in the middle of the upper surface portion 10 and the lower surface portion 12 in the front-rear direction.

  The opera glass 1 is folded as shown in FIGS. 3 and 4 when the product is provided and when not used. The folding is performed by bending the bent portions 16 and 16 of the upper surface portion 10 and the lower surface portion 12 so that each of the bent portions 16 and 16 protrudes outward. In the folded state, the protruding portions 15 and 15 are respectively connected to the objective lenses 2 and 2. It is located so as to cover the entire front surface portion 4 provided. Each of the bent portions 16 and 16 is stretched, and the upper surface portion 10 and the lower surface portion 12 are formed into a planar shape to be used.

  The opera glass 1 prevents the light from directly reaching the objective lenses 2 and 2 when the projecting portions 15 and 15 projecting forward are used, so that the light is not disturbed even in an environment where sunlight is strong. You can see things. In addition, when the product is provided, it can be folded and flattened so that a large number of items can be stacked and packed, and the flat and compact form can be easily carried. Further, in this case, each of the protrusions 15 and 15 covers and protects the objective lenses 2 and 2 to prevent damage.

  FIG. 5 is a development view of the cardboard P constituting the opera glass 1, and the assembly configuration of the opera glass 1 will be described with reference to this figure. FIG. 5 shows the inner surface side of the cardboard P, which includes bent portions at positions A, B, C, D, E, F, and G in the longitudinal direction, and connecting holes 25 on both sides of the portion between the A and B positions. , 25 are provided on both sides of the portion between the E and F positions, and protruding connection portions 28, 28 provided with connecting ends 27, 27 are integrally provided.

  A pair of circular holes 30, 30 are formed in the portion of the cardboard P between the A and B positions, which is the front surface portion 4, and the objective lens plates 2 and 2 are positioned in the circular holes 30 and 30, respectively. 31 is attached to the inner surface of the thick paper P, and a pair of circular holes 32, 32 are formed in the portion of the thick paper which becomes the rear surface portion 8 between the E and F positions. An eyepiece plate 36 is attached to the inner surface of the cardboard P so that the eyepieces 6 and 6 are positioned on the respective parts 32. Further, hanging belt attaching holes 33 and 33 are provided on both side positions of the rear portion of the upper surface portion 10 between the positions F and G of the thick paper P, respectively.

  Assembling is performed by folding in a predetermined direction at each position of A, B, C, E, F, and bonding the inner surfaces of the front end portions with a predetermined width X and connecting them in an annular shape. 28, 28 are folded inward at the positions of H, H, I, I, and the connecting ends 27, 27 are fitted into the connecting holes 25, 25 and connected.

  As a result of the above assembly, the part between A and B of the cardboard P becomes the front face part 4, the part between J and E becomes the upper face part 10, the part between E and F becomes the rear face part 8, and the part between F and K becomes the lower face part 12, The connected projecting connecting portions 26 and 28 become the side surface portion 14, and further, the portion bonded and fixed at the predetermined width X of the front end portion becomes the lower projecting portion 15, and the portion between B and C and the portion between C and J The overlapping portion becomes the upper protruding portion 15.

  With the above configuration, as the upper surface portion 10 and the lower surface portion 12 are bent at the bent portions 16, 16, the both side surface portions 14, 14 are inside at the connecting positions of the projecting connecting portions 26, 26, 28, 28. It is bent by this, and the whole is folded by this and becomes a flat form. Moreover, when both the projecting parts 15 and 15 are continuously located flush with the upper surface part 10 and the lower surface part 12, the upper edge and the lower edge of the front surface part 4 in the assembled state are reinforced, and when receiving external force Also prevents distortion at the corners.
