Description

[Detailed description of the invention] The present invention relates to a seed cover including an expandable outer frame 10 and an outer frame 1.
0, the rear end of the outer frame 10 is folded back to the inner circumference of the outer frame 10 and is bent at the folded tip of a bent piece 13. This is a sleeping cover in which the peripheral end of the end plate 4 is held between a detachment prevention piece 12 and a frame piece 11 extending to the front end of the inner periphery of an outer frame 10.

With conventional saliva covers, the size was determined from the beginning, so they could only be attached to seeds of a predetermined size.

However, since seeds are made from processed wood, each one is slightly different in size even if they are the same size. There are disadvantages in that a gap is created or the insert cover cannot be attached, and furthermore, if the seed size is different, a different size insert cover must be prepared.

Therefore, various methods have been considered in which the outer frame of the insert cover can be adjusted to expand or contract, but if the outer frame of the insert cover can be adjusted to expand or contract in this way, the end plate will need to be constructed separately from the outer frame. There is.

There was a risk that the mirror panel would come off the outer frame during construction.

The present invention was devised in view of the above points, and its purpose is to allow the installation of various sizes of inserts without the risk of creating gaps, etc. The object of the present invention is to provide an insertion cover that does not have the risk of coming off.

The present invention will be explained in detail below with reference to Examples.

The outer frame 10 is formed by combining four corner frames 3 into a square frame shape.

The corner frame 3 is bent into an L shape by the insertion piece 1 and the inserted piece 2, and the tip of the insertion piece 1 is a sliding part 5 with a narrowed diameter. A frame piece 11 has a bent shape around the periphery.

Furthermore, the rear end of the corner frame 3 is bent back toward the inner surface of the corner frame 3, and a detachment prevention piece 12 is attached to the tip of this bent piece 13.
It is formed by bending inward of the corner frame 3.

In order to attach the sleeping cover A constructed as described above to the tip of the insert 8, first arrange the four corner frames 3 to form a rectangle as shown in FIG. The slide portion 5 of the insertion piece 1 of the other corner frame 3 is inserted into the inner periphery of the insertion piece 2 of one corner frame 3 in a shallow or deep manner.

By adjusting the insertion depth of the slide portion 5 into the inserted piece 2, the vertical and horizontal width dimensions of the outer frame 10 can be adjusted.

When assembling the corner frames 3, insert the peripheral end of the end plate 4 between the frame piece 11 and the detachment prevention piece 12 of each corner frame 3, and combine the four corner frames 3 to form the outer frame 10. When formed, the mirror plate 4 is held between the frame piece 11 and the detachment prevention piece 12 and held within the outer frame 10.

In this way, the upper and lower widths of the outer frame 10 are adapted to the size of the insert 8, and the seed cover A is attached to the tip of the seed 8 as shown in FIG.

As mentioned above, each member for configuring the seed cover A is formed of a metal plate such as a copper plate, or a synthetic resin-coated metal plate with a synthetic resin coated on the entire outer surface of a metal plate with a thickness of about 0.4 mm. The surface of a copper plate or copper plated plate is colored with sulfur, and then a scratch pattern is applied to give it an oxidized copper-like appearance, and then this is coated with a transparent synthetic resin baking paint such as alkyd, melamine, or polyester. It is something that is formed from something that has been made.

As mentioned above, the size of the outer frame of the seed cover of the present invention can be adjusted, so it can be adjusted and installed to match the size of the tip of the seed. Since the peripheral edge of the mirror plate is sandwiched between the extended frame piece and the detachment prevention piece provided on the inner periphery of the outer frame, the outer frame can be expanded and contracted so that the mirror plate can be separated from the outer frame. Although it is necessary to configure this structure, the mirror plate is held between the frame piece and the detachment prevention piece, and the mirror plate is held within the outer frame.
There is no risk of the mirror panel coming off the outer frame during construction.

In addition, the detachment prevention piece that suppresses the mirror plate is provided at the folded end of the bent piece that folds the rear end of the outer frame to the inner circumference of the outer frame, so welding etc. is required to form the detachment prevention piece on the inner circumference of the outer frame. It does not need to be used and can be done by bending, making it easy to manufacture.
