Description

[Detailed Description of the Invention] (Field of Application of the Invention) This invention relates to an alligator-shaped hinge that is particularly suitable for use in attaching a lid made of soft glass to a cabinet or the like so as to be openable and closable.

(Background Art) Hitherto, a hinge commonly known as an alligator-shaped hinge, as shown in Utility Model Publication No. 52-32405, has been used to open and close a glass lid covering the top surface of a turntable of an audio device such as a record player. is used. This alligator-shaped hinge has a support member with a structure in which an upper jaw member and a lower jaw member are opposed to each other at a fixed interval attached to a mounting member that is attached to the cabinet side, and is rotatably attached via a hinge pin. It has a structure in which the lid body is held between the lower jaw member and the supporting member is shaped like a crocodile's mouth, so it is called an alligator-mouth type hinge.

By the way, tempered glass is generally used for the lid, but since it is expensive, a cheaper soft glass may be used instead. Normally, two alligator-shaped hinges are installed at different positions on the left and right sides of the lid, but in the conventional alligator-shaped hinge described above, the part of the support member that clamps the lid swings in the horizontal and vertical directions. Therefore, if you attach a soft glass lid whose surface is not flat, slightly wavy or warped to the supporting member of this alligator-shaped hinge, the attachment position may not match. There was a high risk that excessive force would be applied to the lid and it would break.

(Technical Problem) In order to achieve the above-mentioned purpose, this invention has a mounting member attached to the cabinet side.
A support member configured to sandwich a glass lid between an upper jaw member and a lower jaw member is rotatably attached via a hinge pin, wherein the support member is attached to either the upper jaw member or the lower jaw member. Consisting of a rotating part, one of which is pivoted to the hinge pin, and a lid holding plate attached to the rotating part via a support pin so as to be swingable in a direction perpendicular to the mounting surface of the lid. At the same time, the other one can be similarly pivoted in a direction perpendicular to the mounting surface of the lid through a tightening screw to the rotating part, and the lid can be tightened between the one and the other. It is installed.

(Function) By configuring as described above, when attaching the soft glass lid to the support member, even if the lid is warped or wavy, the lid constituting the support member can be moved in that direction. The clamping plate and the members of the upper jaw member and the lower jaw member attached to the rotating part via the tightening screws respectively swing.

(Embodiment) An embodiment of this invention will be described below in detail based on the drawings.For example, the upper rear end of the cabinet 1 of a record player, etc., has a substantially convex planar section and also serves as a spring case. The mounting member 2 fixes the mounting parts 2a, 2a. At the upper end portions of both side plates 2b, 2b of this mounting member 2, a pivoting portion 31b, which will be described later, of a support member 3 having an alligator-mouth shape is rotatably attached by a hinge pin 4. This support member 3 has a sliding member 5 housed in the mounting member 2.
is pivoted by a pin 9 at a position different from the hinge pin 4, and between this sliding member 5 and a catch seat 7 attached to the bottom plate 2c of the mounting member 2 by an adjustment screw 6, A compression coil spring 8 is elastically installed.

The support member 3 is composed of an upper jaw member 31 and a lower jaw member 32 which is placed opposite to each other at a constant interval. ,
It consists of a lid holding plate 31e which is swingably attached to the tip of the rotating part 31a by means of a support pin 33. The lower jaw member 32 has an insertion portion 3 inserted between both side plates 31b, 31b of the upper jaw member 31.
2a, and a projecting piece 3 provided at the end of this insertion portion 32a.
2b, and the upper edge of this protruding piece 32b has a curved part 3
2c is formed, and this curved portion 32c is in contact with the back surface of the top plate 31c of the upper jaw member 31.
Further, a tightening screw 10 whose head 10a is engaged with an elongated countersink hole 31d provided in a top plate 31c of the rotating portion 31a
The tip of the lower jaw member 32 is screwed into a screw hole 32d provided in the insertion portion 32a of the lower jaw member 32, thereby allowing the lower jaw member 32 to swing in a direction perpendicular to the mounting surface of the lid body 11. .

In addition, the insertion part 32a of the lower jaw member 32 may be made into a straight line shape and curved, or it may be configured to swing by providing a convex line and making it contact with a hinge pin.

Therefore, the two alligator-shaped hinge mounting members 2 constructed as described above are attached in parallel to the rear upper end of the cabinet 1, and then the cover body 1 made of soft glass is attached.
1 is inserted between the lid clamping parts 34 of each support member 3 and each fixing screw 32e and tightening screw 10 are tightened. It is held between the lid holding part 34 consisting of And at that time,
Even if the lid 11 is warped or bent, the lid holding part 34 can swing in a direction perpendicular to the mounting surface of the lid 11, so that the lid 11 can be bent.
This prevents as much force as possible from being applied to the material, and prevents it from breaking.

On the other hand, since the rotating portion 31a and the lid holding plate 31e are connected to each other by the support pin 33, no trouble occurs in the opening and closing operation of the lid 11.
It opens and closes by the same mechanism as known hinges using compression coil springs. Therefore, detailed explanation thereof will be omitted.

FIG. 6 shows another embodiment, and according to the drawing, a lid is held by a support pin 15 at one end of a rotating part 14a of a support member 13 connected to a mounting member 12 by a hinge pin 12a. The plate 14b is pivoted to the mounting surface of the lid 11 so as to be swingable in the vertical direction. The upper jaw member 16 is placed opposite to the upper part of the lower jaw member 14 configured in this manner at a constant interval, and is swingably attached to the rotating portion 14a of the lower jaw member 14 by a tightening screw 17. A lid clamping portion 18 is formed between the upper jaw member 16 configured in this way and the lid clamping plate 14b. A lid body 19 made of soft glass is clamped by the lid clamping portion 18 .

Even if carried out in this way, the lid clamping part 1 consisting of the lid clamping plate 14a which clamps the lid body 19 and the upper jaw member 16
8 is movable in a direction perpendicular to the mounting surface of the lid 11, so that the same effects as in the previous embodiment can be achieved.

Note that the fixing screw 32e may be attached to the upper jaw member 31 as shown in the embodiment of FIG. Alternatively, the tightening screw may be provided by drilling a hole in the lid between the upper jaw member and the lower jaw member.

Next, the mounting member that also serves as the spring case is
For example, as disclosed in Utility Model Publication No. 52-52804, if the upper jaw member has a structure that swings, a structure that is fixed to another cabinet may be used instead. Needless to say, packing may be interposed on one or the other of the lower jaw members as shown in FIG. 6.

(Effects) As explained in detail above, this invention connects the support member to a rotating part formed by pivoting either the upper jaw member or the lower jaw member to a hinge pin, and this rotating part via the support pin. The lid clamping plate is attached to the mounting surface of the lid so that it can swing in a direction perpendicular to the mounting surface of the lid. The lid is constructed so that it can swing in a vertical direction against the glass and can be tightened between the lid and the other, so that the soft glass that is easily broken can warp or wave on the lid. Even if the lid clamping plate constituting the supporting member and the member attached to the rotating part through the tightening screw of the upper jaw member and the lower jaw member are bent or warped, Since the lids oscillate and follow each other, and do not go against them, the lid body does not break and is safe. Furthermore, this has the effect of improving yields and lowering manufacturing costs. It is something.
