Description

Hinge, door device and hinge spacer

The present invention relates to a hinge including a cup that can fit into a mortise on the inner surface of a door of furniture or the like.

ヒンジ Hinges are known that include a cup that can fit into a tenon on the inner surface of a door of furniture or the like (see Patent Document 1). A mounting flange and a marginal (peripheral) flange protrude from the upper edge of the cup. The mounting flange contacts the inside surface of the door adjacent the door mortise. The mounting flange has a through hole through which a fastening member such as a screw passes. The mounting flange is mounted on the inner surface of the door by a fastening member such as a screw. The marginal flange fits into a tenon on the inside surface of the door. The marginal flange has a radius corresponding to the radius of the mortise and is formed in a fan shape. For better appearance, the marginal flange covers the gap between the tub and the mortise of the cup fitted in the mortise.

よう As mentioned above, the mounting flange contacts the inside surface of the door adjacent to the door mortise. On the other hand, the marginal flange fits into the mortise of the door. Therefore, a step is formed between the lower surface of the mounting flange (surface on the door side of the mounting flange) and the lower surface of the marginal flange (surface on the door side of the marginal flange).

By the way, the door in the opening position may be further subjected to a moment in the opening direction. Simply attaching the mounting flange of the cup to the inner surface of the door with a fastening member such as a screw will result in insufficient connection strength when this moment acts. In order to secure the connection strength, the bottom of the bathtub-shaped portion of the cup is brought into contact with the bottom of the mortise of the door. By contacting the bottom of the cup with the bottom of the mortise of the door, this moment can be withstood.

U.S. Pat. No. 4,797,972

However, depending on how the hinge is attached, it may be difficult to bring the bottom of the bathtub-shaped portion of the cup into contact with the bottom of the mortise of the door. For example, in the case of a sheet metal door, it is necessary to attach a bracket for forming the mortise bottom surface to the door, which increases the number of parts. Further, even when a mortise is made in a door of a wooden door, for example, it is difficult to match the depth of the mortise of the door with the depth of the cup.

Therefore, an object of the present invention is to provide a hinge that can secure the connection strength between a cup and a door by using a marginal flange of the cup.

In order to solve the above-mentioned problem, one aspect of the present invention includes a cup that can fit into a mortise on the inner surface of a door, and has a mounting flange and a marginal flange protruding from an upper edge thereof. Wherein a step is formed between the surface of the door side and the surface of the marginal flange on the door side, wherein a spacer is detachably mounted on the surface of the mounting flange on the door side, In the flange and the spacer, a through hole through which a fastening member passes is formed, and in a state where the spacer is mounted on the mounting flange, the surface of the spacer on the door side and the surface of the marginal flange on the door side are substantially formed. Hinges that are coplanar.

Another aspect of the present invention is a hinge spacer including a cup capable of fitting into a mortise on an inner surface of a door, wherein a mounting flange and a marginal flange project from an upper edge of the cup, and A step is formed between the surface of the door on the side of the door and the surface of the marginal flange on the side of the door, and the spacer is detachably attached to the surface of the mounting flange on the side of the door, the mounting flange and the spacer A through hole through which a fastening member is passed is formed, and in a state where the spacer is mounted on the mounting flange, the surface of the spacer on the door side and the surface of the marginal flange on the door side substantially correspond to each other. Hinge spacers on the same plane.

According to the present invention, since the surface of the spacer on the door side and the surface of the marginal flange on the door side are substantially in the same plane, if the mounting flange is mounted on the inner surface of the door by the fastening member, not only the spacer, The marginal flange can contact the inner surface of the door adjacent the mortise. Therefore, the connection strength between the cup and the door can be secured using the marginal flange.

Are provided at symmetric positions of the spacer 21. The socket cover 22 is made of resin.

FIG. 5 is a cross-sectional view (a cross-sectional view taken along line VV in FIG. 1) of the mounting flange 15 and the marginal flange 16b of the cup 4. As described above, the mounting flange 15 and the

marginal flanges

16a and 16b are formed to protrude from the upper edge of the cup 4. As shown in FIG. 5B, a peripheral edge 15 b of the mounting flange 15 is bent toward the door 2 so that a concave portion 15 c is formed in the mounting flange 15. A step h is formed between a surface 15d of the mounting flange 15 on the door 2 side and a surface 16c of the marginal flange 16b on the door 2 side. The step h is, for example, 0.5 to 1.5 mm. The spacer 21 fills the step h. When the spacer 21 is mounted on the mounting flange 15, a surface 21e of the spacer 21 on the door 2 side and a surface 16c of the marginal flange 16b on the door 2 side are substantially on the same plane. The surface 21 e of the spacer 21 and the surface 16 c of the marginal flange 16 b contact the inner side surface 2 b of the door 2. The tub 11 of the cup 4 does not contact the side plate 24 of the door 2, and a gap is opened between the tub 11 and the side plate 24 of the door 2.

In addition, as shown in FIG. 5B, the edge 1 a of the main body 1 hits the marginal flange 16 b of the cup 4 at the closed position of the door 2. A gap g opens between the inner surface 2b of the door 2 and the edge 1a of the main body 1. The frame 24 a of the side plate 24 of the door 2 (see also FIG. 2) protrudes from the inner side surface 2 b of the door 2 toward the main body 1. This prevents the gap g from opening between the main body 1 and the door 2 when the door 2 is closed.

FIG. 6 shows the contact area between the inner surface 2b of the door 2 and the spacer 21 and the

marginal flanges

16a and 16b. S1 represents the contact area between the inner surface 2b of the door 2 and the spacer 21, S2 represents the contact area between the inner surface 2b of the door 2 and the marginal flange 16a, and S3 represents the inner surface 2b of the door 2 and the marginal flange 16b. Represents the contact area. When a moment in the opening direction is further applied to the door 2 in the open position, a moment M shown in FIG. 6 is applied to the cup 4 around the fastening member 17 (see FIG. 1). According to this embodiment, not only the spacer 21 but also the

marginal flanges

16a and 16b contact the inner side surface 2b of the door 2, so that the cup 4 can withstand this moment M, and the connection between the cup 4 and the door 2 Strength can be ensured.

According to the hinge of the present embodiment, the following effects are further obtained. Since the peripheral edge 21b of the spacer 21 is detachably fitted to the outside of the peripheral edge 15b of the mounting flange 15, the spacer 21 can be mounted on the mounting flange 15 so as not to easily fall off. Therefore, the work of attaching the cup 4 to the door 2 becomes easy.

(4) Since the engaging portion 21d that engages with the socket cover 22 is formed on the spacer 21, it is not necessary to form an engaging portion on the cup 4, and the cup 4 is easily manufactured.

FIG. 7 shows an example in which the hinge 10 of the present embodiment is attached to a wooden door 32. FIG. 7A shows a state where the cup 4 is attached to the door 32, and FIG. 7B shows a state where the cup 4 is removed from the door 32. The door 32 has a circular mortise 32a. The depth of the mortise 32a matches the depth of the bathtub-like portion 11 of the cup 4. When attaching the cup 4 to such a door 32, the spacer 21 is removed from the attachment flange 15 of the cup 4. Then, the mounting flange 15 is directly mounted on the inner surface 32 b of the door 32 by the fastening member 17. The

marginal flanges

16a and 16b fit into the mortise 32a of the door 32 and cover the gap between the tub-like portion 11 of the cup 4 and the mortise 32a. The upper surfaces of the

marginal flanges

16a and 16b are substantially flush with the inner side surface 32b of the door 32. In this example, since the bottom of the bathtub-shaped portion 11 of the cup 4 can be brought into contact with the bottom surface 32c of the mortise hole 32a of the door 32, the connection strength between the cup 4 and the door 32 can be ensured.

FIG. 8 shows an example in which the hinge 10 of the present embodiment is attached to another wooden door 42. FIG. 8A shows a state where the cup 4 is attached to the door 42, and FIG. 8B shows a state where the cup 4 is removed from the door 42. The door 42 has a rectangular mortise 42a. The depth of the mortise hole 42 a can be made to match the depth of the bathtub-like portion 11 of the cup 4, or can be greater than the depth of the bathtub-like portion 11. When the cup 4 is attached to such a door 42, the spacer 21 is attached to the attachment flange 15 of the cup 4 as in the case of the cup 4 shown in FIG. Then, a step between the mounting flange 15 and the

marginal flanges

16a, 16b is filled with the spacer 21, and the spacer 21 and the

marginal flanges

16a, 16b are brought into contact with the inner side surface 42b of the door 42. Thereby, the connection strength between the cup 4 and the door 42 can be secured. If the bottom of the tub 11 of the cup 4 is brought into contact with the bottom surface 42c of the mortise 42a of the door 42, the connection strength between the cup 4 and the door 42 can be further improved.
