Description

The present invention relates to a door mounting structure and a hinge used therein.

In various types of equipment where airtightness is important, packing is used to ensure airtightness. The periphery of the packing is filled with caulking material for the purpose of fixing the packing and improving airtightness and waterproofness. For example, in the case of a glove box that has a main body with an opening and a door for opening and closing the opening, a packing (hereinafter referred to as A sealing material (referred to as a "sealing material") is provided (Patent Document 1), and a caulking material is filled around the periphery of the sealing material.

Japanese Patent Application Publication No. 2010-131713

However, there is a risk that caulking material may peel off due to aging or physical contact, and may become contaminated as impurities. Further, when using caulking material, there are disadvantages in that it takes a long time to dry, and in that it is difficult for users to replace and maintainability is low.

If caulking material is not used, a hollow gasket called Inflat Seal (registered trademark; the same applies hereinafter) may be used, but inflat seals have the disadvantage that it takes time to manufacture the parts, and they are difficult to replace by the user and are difficult to maintain. The disadvantage is that it is low.

In addition, the sealing material provided on the back side of the door does not have the strength of caulking material because it rubs against the main body when the door is opened and closed, and may break due to repeated opening and closing of the door. Ta.

The present invention was made in view of the above circumstances, and the problem to be solved is to prevent the sealing material from coming into contact with the main body when opening and closing the opening/closing door, without the drawbacks of using caulking materials or inflated seals. It is an object of the present invention to provide a door mounting structure that can avoid the risk of damage to the sealing material and a hinge used therein.

[Door mounting structure]
The door mounting structure of the present invention includes a main body, an opening/closing door, and a hinge connecting the main body and the opening/closing door. The hinge includes a first member fixed to the main body, a second member fixed to the opening/closing door, and a connector rotatably connecting the first member and the second member, The first member is provided with a pressing means, and the second member is biased away from the main body by the action of the pressing means.

[Hinge]
The hinge of the present invention includes a first member fixed to the main body, a second member fixed to the opening/closing door, and a connector rotatably connecting the first member and the second member, and the first member is provided with a pressing means, and is configured such that the second member is urged away from the main body by the action of the pressing means.

Since the door mounting structure of the present invention does not use caulking material or inflated seals, it does not have the disadvantages of using these materials. In addition, since the second member is urged away from the main body by the pressing means, the sealing material is prevented from coming into contact with the main body when the opening/closing door is opened and closed, thereby reducing the risk of damage to the sealing material. can. In the hinge of the present invention, since the second member is urged away from the main body by the pressing means, it contributes to realizing the door mounting structure.

(Embodiment)
An example of an embodiment of the door mounting structure and hinge of the present invention will be described with reference to the drawings. Here, a glove box in which the door mounting structure and hinge of the present invention are used will be taken as an example.

As an example, the glove box shown in FIGS. 1 and 2 mainly includes a main body 10 with a front opening and a work space S, and an opening/closing door 20 that opens and closes the front opening 17 of the main body 10.

The main body 10 is a box-shaped case with a work space S. The main body part 10 of this embodiment has a hexahedral shape including a front part 11 , a right side part 12 , a back part 13 , a left side part 14 , a top part 15 , and a bottom part 16 . A front opening 17 is provided at the front.

A box 18 used for measuring instruments, lighting equipment, and other purposes is provided at the top of the main body 10. The box 18 can also be provided in a part other than the upper part of the main body part 10. The box 18 may be provided as necessary, and may be omitted if unnecessary.

The main body 10 of this embodiment is supported by four legs 19. Casters 19a are provided at the lower ends of the legs 19 for moving the glove box. An H-shaped reinforcing frame 19b is provided between the four legs 19. The leg portions 19 may have a configuration in which the height can be adjusted by providing an adjuster instead of the casters 19a, or a configuration in which the leg portions 19 can be fixed with anchors.

The opening/closing door 20 is a confirmation door for observing the work space S of the main body section 10, and includes a frame section 21, a glass plate (hereinafter referred to as "front glass plate") 22, and a globe 22f. As an example, the frame portion 21 shown in FIGS. 1 and 2 is a horizontally rectangular member that includes accommodation portions 24 (FIG. 4(a)) in which the front glass plate 22 is accommodated inside the four sides of the top, bottom, left, and right. The frame portion 21 can be made of a square tube or the like.

As shown in FIG. 3(a), there are L-shaped guides 25a made of two L-shaped members at the four corners of the back side of the frame part 21, and two L-shaped guides 25a are arranged between each L-shaped guide. An I-shaped guide 25b made of an I-shaped member is provided. The four L-shaped guides 25a and the four I-shaped guides 25b are provided at intervals.

In this embodiment, the sealing material guide 25 is composed of four L-shaped guides 25a and four I-shaped guides 25b, and a rubber A sealing material 26 is attached in a ring shape.

As shown in FIGS. 3(b) and 3(c), the two members constituting each L-shaped guide 25a and each I-shaped guide 25b have tapered surfaces that oppose each other, and The spacing becomes narrower toward the free end side. By doing so, the sealing material 26 that fits between the two members becomes difficult to come off, and it is possible to prevent the sealing material 26 from accidentally falling off.

As shown in FIG. 3(b), when the sealing material 26 is fitted all the way into the sealing material guide 25, a portion of the sealing material 26 protrudes outward from the end surface of the sealing material guide 25. As shown in FIG. 3(c), the portion of the sealing material guide 25 that protrudes outward from the end surface is pressed against the front side of the main body 10 when the door 20 is closed, thereby causing the main body 10 and the door 20 is ensured.

Note that the reason why the sealing material guide 25 is not structured to extend around the entire circumference of the frame portion 21 (rectangular shape), but is made to have a discontinuous structure with a gap between the L-shaped guide 25a and the I-shaped guide 25b is because This is to prevent water used for cleaning from accumulating inside the sealing material guide 25. As in this embodiment, by configuring the sealant guide 25 with the L-shaped guide 25a and the I-shaped guide 25b that are not continuous, the water used for cleaning can be transferred to each of the L-shaped guides 25a and the I-shaped guides 25b. It is possible to prevent the liquid from flowing down from the end portions and accumulating inside the L-shaped guide 25a or the I-shaped guide 25b.
