Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a lens storage case, and particularly to a storage case that can be cleaned, transported, etc. while being stored during the manufacturing process.

(Prior art) Conventionally, during the manufacturing process, cleaning of a single lens,
For transportation and storage, single lenses are usually held in a method suitable for the purpose for each process.When cleaning with a washing machine, a single lens is held by its outer periphery; A method of maintaining the polished surface is adopted.

(Problem that this invention attempts to solve) ``Polishing'' is necessary to protect the polished surface of a single lens.
Ideally, only the outer periphery of a single lens should be retained once the process is completed, but the outer diameter of a single lens varies depending on the type, and even for the same single lens, the outer diameter may change before and after centering. Because of this, the conventional method of holding the outer periphery of a single lens requires a dedicated case for each lens.

Therefore, it is expensive and difficult to manage, so in most cases, a cleaning basket is used only for cleaning, and for other processes, a rectangular box (commonly known as a ``dish'') is lined with malt plane and tissue paper. A method is used in which single lenses are arranged with their polished surfaces facing up and down.

A single lens is cleaned many times from the time polishing is completed to the time it is assembled, so each time the lens must be transferred from the cleaning basket to the dish, which requires a large number of steps and is extremely troublesome. be.

This invention was developed in view of the above-mentioned circumstances, and allows single lenses with different outer diameters to be stably held at their outer peripheries without any adjustment, and cleaning, transportation, storage, etc. can all be performed within the same case. The objective is to obtain a lens storage case that is designed as such.

(Means for Solving the Problem) The lens storage case of this invention includes a locking member provided along the front and rear walls of the case and having a V-groove that abuts the peripheral edge of the lens to be placed, and and a U-shaped member rotatably supported around an axis parallel to the wall, and each of the U-shaped members is provided with a V-groove at its distal end, and the two U-shaped members are provided with a V-groove at a predetermined distance apart from the lens. By coming into contact with the peripheral part, U
It is characterized in that the lens periphery is supported at three separate locations on the circumference by the two V-grooves of the shaped member and the V-groove of the locking member.

(Example) The present invention will be specifically described below with reference to the drawings.

In the embodiment shown in FIGS. 1 to 4, the storage case 1 has side walls 3, 3, front and rear walls 2, 2 extending to approximately half the height of the side walls, and an intermediate wall 4, and the bottom and top surfaces are All will be released. Front and rear walls 2
A locking portion 5 is horizontally protruded above the locking portion 5, and a plurality of V grooves 5a for holding the single lens L are formed at the tip of the locking portion 5. The storage case 1 is integrally molded from a synthetic resin with strong solvent resistance.

A shaft 6 is installed between the side walls 3, 3, and a U-shaped member 7 made of a synthetic resin with strong solvent resistance is supported on the shaft 6. As shown in FIG. 4, the U-shaped member 7 consists of a rising part 7a and a bottom part 7c, and a V-groove 7b is formed at the tip of the rising part 7a, and a fitting part 7d with a cut groove 7e is formed at the lower part of the bottom part 7c. Form integrally. The V groove 7b holds the lower part of the single lens L at two points. When the cut groove 7e of the fitting portion 7d is fitted onto the shaft 6, the fitting portion 7d is rotatably supported by the shaft 6 due to its elastic force.

A crank-shaped presser lever 8 is rotatably installed on the side wall 3, and the upper part of the single lens L is held by the presser lever 8. The locking spring 9 has a hook-shaped portion 9a at its tip that locks on the presser lever 8, a loop portion 9b at its intermediate portion to provide spring properties, and a loop portion 9b that locks on the intermediate wall 4 to serve as a pivot for rotation. Each has a root portion 9c.

A plurality of notches 10a are provided in the intermediate wall 4, one end of which communicates with the elongated hole 10b.
The root portion 9c of the locking spring 9 is locked in place. This locking position can be changed by selecting the notch portion 10a, and the height of the hook-shaped portion 9 can be adjusted as desired.

The outer periphery of the single lens L is held at three points: the V groove 5a of the locking part 5 and the two V grooves 7b of the U-shaped member 7, and then pressed from above with the presser lever 8, and the locking spring 9 is The hook-shaped portion 9a is locked to the presser lever 8. As a result, the single lens L is held vertically and firmly.

FIG. 5 is a diagram showing the state of contact with the outer periphery when holding single lenses with different outer diameters. When holding a single lens L' shown by a dotted line and having a larger diameter than the single lens L shown by a solid line, The U-shaped member 7 rotates around the O point, that is, the axis 6, from the solid line position to the dotted line position 7', and holds the outer periphery of the large-diameter single lens L'.

In this way, even if the outer diameter of the single lens L changes, the U-shaped member 7 follows it and rotates around the shaft 6, so the single lens L can be adjusted without adjusting the V groove 5a of the locking part 5. It is stably held by two V grooves 7a of the U-shaped member 7.

In order to stack the storage cases 1 with good stability, the side wall 3 is formed with a convex portion 3a at the top and a concave portion 3c at the bottom. Furthermore, a protrusion 3b protruding outward is formed on the side wall 3c,
The protrusion 3b serves as a hook when the storage case 1 is placed in a washing machine (not shown).

Another embodiment shown in FIGS. 6 to 8 has similar components indicated by the same reference numerals as the previous embodiment, but in addition the shaft 6 has a variable position mechanism.

The side wall 3 is provided with connected square holes 10 in which the corners of a plurality of rectangular holes 10a are overlapped with each other.

The shaft 6 has a bearing member 11 fitted into a rectangular hole 10a.
It is installed on the side wall 3 via.

As shown in FIG. 8, the bearing member 11 has a flange portion 11a and a rectangular boss portion 11b, an eccentric shaft hole 11c penetrating both of these portions, and a rectangular boss portion 1.
Diagonal grooves 11d are formed in each of the grooves 1b. Further, the bearing member 11 is made of a synthetic resin with elasticity and strong solvent resistance.

The C-shaped short spacer 12 fits into the end of the shaft 6 to maintain the distance between the bearing member 11 and the U-shaped member 7.
A long C-shaped spacer 13 is fitted into the center of the shaft 6 to maintain a predetermined distance between the U-shaped members 7 in the center. These spacers are all made of elastic, solvent-resistant synthetic resin.

In the above configuration, a required number of U-shaped members 7 and bearing members 11 are fitted on both sides of the shaft 6, respectively. Place this in the storage case 1, and
1 is fitted into a predetermined rectangular hole 10a from the inside of the side wall 3. The assembly is then completed by inserting the short spacer 12 between the bearing member 11 and the U-shaped member 7, and the long spacer 13 between the U-shaped members 7, 7 in the center of the shaft 6, respectively.

Since the shaft hole 11c formed in the bearing member 11 is eccentric, by rotating and fitting the bearing member 11 into one rectangular hole 10a, it is possible to select four positions of the shaft 6 supported by the shaft hole 11c. It is. Therefore, when four rectangular holes 10a are formed as in this embodiment, the positions can be adjusted in 16 locations.

When the shaft 6 has a variable position mechanism as described above, it is possible to precisely support single lenses having different outer diameters, further increasing the versatility of the same storage case.

(Effects of the invention) With the above configuration, the U-shaped member rotates around the axis to follow changes in the outer diameter of the single lens, so that the single lens can be Regardless of the situation, it is stably held without any adjustment by the V-groove in the locking part and the V-groove at the tip of the U-shaped member. Moreover, since stable holding is achieved only by the outer periphery without touching the polished surface, cleaning, transportation, storage, etc. can be carried out in the same case, which has a remarkable practical effect.
