Abstract

PURPOSE:To omit coating operation of an adhesive agent, to facilitate joining operation and to prevent the surface of the sphere from becoming dirty owing to leakage by fixing joined edges formed at the peripheral edge parts of a couple of a hemispherical shell bodies together with a double coated adhesive tape whose top and reverse surfaces are both coated with the adhesive agent. CONSTITUTION:When both the hemispherical shell bodies 2 are joined together, the double coated adhesive tape 5 is stuck on the surface of the joined edge 2a of one shell body and water is applied on its exposed surface side; and the joined edge is fitted in the joined edge 2b of the other shell body, so that both hemispherical shell bodies are easily joined together with efficiency. Consequently, the operation for coating the joined surfaces with the adhesive agent is not necessary to facilitate the joining operation and improve its efficiency, and the surface of the sphere never becomes dirty owing to leakage of the adhesive agent. Further, both the joined edges 2a and 2b of the shell bodies 2 can be fixed with a uniform adhesive strength to over the entire periphery to stabilize the joining strength.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a spherical body applied to a terrestrial globe or the like.

Conventional Technique #4] Conventionally, when creating a sphere for a globe, adhesive is applied to the peripheral edges of a pair of hollow hemispherical shells, and both peripheral edges are polymerized and fixed. The shells for both hemispheres were joined.

[Problems to be Solved by the Invention] In the case of the above-mentioned method of joining the shells for both hemispheres, the work of applying adhesive to the periphery of the hemispherical shell is complicated, and the adhesive may not be applied too much or too little. As a result, the adhesive may leak from the joint between the shells for both hemispheres, and the joint state of the shells for both hemispheres may become unstable.

It is an object of the present invention to solve the above-mentioned problems and simplify the work of joining shells for both hemispheres, as well as to stabilize and improve the joint state of shells for both hemispheres.

[Means for Solving Problem 1] The sphere for a sphere of the present invention is a sphere for a sphere formed by joining a pair of hollow hemispherical shells, and the periphery of the shells for both hemispheres is Each part is formed! It has a structure in which the two folded joint edges are fixed by double-sided adhesive tape with adhesive applied to both the front and back surfaces, respectively.

[Function] Both joint edges formed on the peripheral edges of a pair of shells for hemispheres are overlapped and fixed via a double-sided tape coated with adhesive on both the front and back surfaces, and the shells for both hemispheres are bonded together. Join the shells.

[Effects of the Invention] Since the present invention is configured as described above, there is no need to apply adhesive to the joint edges, which simplifies and streamlines the work of joining shells for both hemispheres. This has the effect of eliminating the problem of contamination of the surface of the sphere due to leakage from the joint.

In addition, it is possible to fix both joint edges of the shell for both hemispheres with uniform adhesive force over the entire circumference, and to equalize the adhesive force of the joint of the shell for both hemispheres at d5 between each sphere, This has the effect of stabilizing the bonding strength of both hemispheres by eliminating the problem that the adhesive force between the two bonding edges fluctuates within the sphere or between the spheres.

[Example] Next, one embodiment of the present invention will be described with reference to the drawings.

A hollow sphere 1 is rotatably supported on a bow rest 8 which is attached to the upper end of the support base 7 of the globe G and is curved into an arc.

The ball rest 1 is formed by a pair of hemispherical shells 2, 2 each shaped into a hollow hemisphere shape to display the southern hemisphere and the northern hemisphere, and joined face-to-face via a joint 20 where their peripheral edges are overlapped. has been done.

A display FfI 3 formed by three-dimensionally molding a thin display layer plate made of a synthetic resin material into a hemispherical shape and displaying map figures for the southern hemisphere and the northern hemisphere is disposed on the surface layer of the shell body 2 for both hemispheres. At the same time, on the back side of this display layer 3, a transparent inner shell layer 4 formed by injection molding of a synthetic resin material is integrally laminated. A joining edge 2a formed by recessing the outer surface of this peripheral edge in a step-like manner is provided around the peripheral edge of one hemisphere shell 2, and a connecting edge 2a is formed around the peripheral edge of the other hemisphere shell 2. is a joining edge 2b formed by recessing the inner surface of this peripheral edge in a step-like manner.
is provided around the periphery, and the shells 2 for both hemispheres are joined with the joining edges 2a and 2b overlapped.

Both display layers 3 have a white coating film applied to both the front and back sides of a transparent base layer, and a printing E3a on which printing is performed on both white coating films, respectively, and a printing layer 3a coated on both sides of the front and the guest side of the printing layer 3a. The transparent protective IMs 3b and 3b are integrally laminated and formed, respectively, and a display layer 3 for the southern hemisphere and a display layer 3 for the northern hemisphere are prepared in advance.

Both joining edges 2a of the joined shells 2 for both hemispheres. A double-sided adhesive tape 5 having a tape width slightly shorter than the width of the joining edges 2a and 2b is interposed between the two hemisphere shells 2 over the entire circumference, and is coated with an adhesive on both the front and back surfaces of the tape 2b. At the joint portion 20, both joint edges 2a and 2b are superimposed and fixed via a double-sided adhesive tape 5.

Both joining edges 2 of the shell 2 for both hemispheres are bonded by the double-sided adhesive tape 5.
When fixing parts a and 2b, apply adhesive 15 to the surface of the joining edge 2a (2b) of one hemispherical shell 2, and apply water to the exposed side of the attached double-sided appetizer tape 5. While temporarily reducing the adhesive performance of one side of the adhesive 1-75, the joining edge 2b (2a) of the other hemisphere shell 2 is bonded to the joining edge 2a (2b) to which the double-sided adhesive tape 5 is attached. ) and leave it for a predetermined period of time, the water applied to the side of the double-sided adhesive tape 5 will naturally evaporate, and the adhesive performance on one side will be developed again, and both joining edges 2a and 2b will be bonded to both sides. It can be fixed by adhesive tape 5.

Next, the operation and effects of the embodiment having the above configuration will be explained.

In the wooden example, in a sphere 1 formed by joining a pair of hollow radius-shaped hemisphere shells 2, both joint edges 2a. 2b
A double-sided adhesive tape 5 having adhesive applied to both the front and rear surfaces is interposed in between to fix both the joining edges 2a and 2b.

When joining the shells 2 for both hemispheres, double-sided adhesive tape 5 is attached to the surface of the joint edge 2a of one hemisphere shell 2, and water is applied to the exposed surface side of the double-sided adhesive tape 5. By fitting this joining edge 2a into the joining edge 2b of the other hemisphere shell 2, both hemisphere shells 2 can be easily and efficiently joined.

Therefore, there is no need to apply adhesive to the joint surfaces,
This simplifies and streamlines the work of joining the shells 2 for both hemispheres, and also eliminates the problem of adhesive leaking from the joint and staining the surface of the sphere.

In addition, both the joints 1t2a and 2b of the shell 2 for both hemispheres are fixed with uniform adhesive force over the entire circumference, and the joint 20 of the shell 2 for both hemispheres in the sphere 1 and the shell 2 for both hemispheres is bonded. The force can be balanced, and the problem of the adhesive force between both joining edges 2a and 2b fluctuating within the sphere 1 or between the spheres 1 is eliminated, and the joint strength of the shell 2 for both hemispheres is stabilized. It has a potential effect.
