Description

[Detailed description of the invention] The present invention relates to a hinge device with adjustable spacing, which is attached to two butterfly plates that are provided so that the hinge can be freely opened and closed, and in which the mutual spacing between mounting members can be expanded and contracted. .

Traditionally, there have been three picture frames that can be folded together to hold bromides, photographs, paintings, etc. on a desk, and so-called three-sided mirrors.
Other plate-shaped bodies are foldably connected as shown in Fig. 1, by completely folding the plate-shaped bodies at both ends inwardly.
Folding into so-called three layers (as shown in Figure 2)
Due to the thickness of the folded plates, the plates must be connected from the beginning with an interval greater than the thickness of the plates, and the three plates must be connected closely together. As shown in FIG. 1, it has been impossible to connect these to be foldable and fold them into three layers from both sides.

The present invention solves these problems and connects three plate-shaped bodies closely to each other so that they can be folded freely, and has an interval that allows them to be folded inward from both sides into three layers. The object is to provide an adjustable hinge device.

The present invention will be explained based on the drawings. In FIGS. 1 to 3, 1 is a hinge.

The hinge 1 engages and communicates shaft stop tubes 3 provided alternately on the longitudinal side edges of two rectangular butterfly plates 2, and a support shaft 4 is inserted into the shaft stop tubes 3. This is a known hinge in which two butterfly plates 2 are pivoted to open and close freely.

Reference numeral 5 denotes a slide hole, which is bored in the width direction of the butterfly plate body 2 of the hinge 1, which is the short direction.

The slide hole 5 is bored outward in a direction perpendicular or obliquely to the width direction of the butterfly plate body 2, that is, to the pivoting direction.

Reference numeral 6 denotes a locking pin, and the locking pin 6 can be a nail, a wood screw, or any other suitable member.
In order to attach the locking pin 6 to the mounting member 7 via the locking pin 6, the head of the locking pin 6 needs to have a diameter larger than at least the width of the slide hole 5.

To use the hinge according to the present invention, the locking pin 6 and the slide hole 5 of the butterfly plate body 2 of the hinge 1 are slidably penetrated to form a part of the frame body of the plate-like body 8 such as a picture frame. Loosely insert and lock into the mounting member 7 to install.

In this case, among the hinges used to connect the three plate-like bodies 8,
As shown in FIG. 1, the hinge of the present invention is used for one of the left and right plate bodies 8, and a conventionally known hinge is used for the other hinge.
Three plate-like bodies 8 are closely connected to each other.

In order to fold the three plate-like bodies 8 foldably connected into a triple stack, that is, into the state shown in FIG. 8, and then the plate-like bodies 8 connected by the hinge according to the present invention were pulled outward to open the distance between the connected plate-like bodies 8, and then folded in half. It is superimposed above the plate-like body 8 and folded into three layers.

As shown in FIG. 3, slide holes 5 are formed obliquely and parallel to both ends of the butterfly plate body 2 in the width direction, so that the mounting members 7 connected by the hinge 1 of the present invention can be easily attached. When opening the gap, the locking pin 6 inserted into the slide hole 5 will not slide and the gap will not open unless it is pulled outward to a certain extent, as shown in Figure 1. When the three panels are connected and opened in the state shown in the figure, there is no risk of the gap becoming widened by a small amount of force, such as when a slight vibration occurs or when the panels are lifted by hand.

FIG. 4 shows yet another embodiment of the present invention, in which the slide hole 5 is formed in an abbreviated shape, and is bored at symmetrical positions in the direction of both ends of the butterfly plate body 2 to support the slide hole 5. The axis 4 direction is formed parallel to the support shaft 4.

In this way, the slide holes 5 are formed in an abbreviated shape and are bored at symmetrical positions in the direction of both ends of the butterfly plate body 2, and the direction of the support shaft 4 is parallel to the support shaft 4. From, hinge 1
When the distance between the mounting members 7 connected to each other does not need to be increased, that is, when maintaining the distance shown in FIG. If it is inserted and locked in the bent position, there is no fear that the gap will become wider even when it is pulled or lifted.

FIG. 6 shows still another embodiment of the present invention, in which the locking pin 6 is a wood screw 9, and the wood screw 9 is attached to a mounting member 7.
It is provided so that it can be screwed into.

In this way, since the locking pin 6 is a wood screw 9 and the wood screw 9 is provided so as to be screwable into the mounting member 7, the hinge 1
This has the effect that it can be easily attached to the attachment member 7.

FIG. 5 shows still another embodiment of the present invention, in which the mounting member 7 is made of synthetic resin or metal, a nut 10 is fixed or embedded in the mounting member 7, and the locking pin 6 is attached to the bolt 1.
1, the bolt 11 is provided so as to be screwable into the nut 10.

In this way, when the mounting member 7 is made of synthetic resin or metal, the nut 10 is fixed or buried in the mounting member 7, and the locking pin 6 is used as the bolt 11, and the bolt 11 is attached to the nut 10.
Since the hinge 1 can be screwed onto the mounting member 7, the hinge 1 can be easily mounted on the mounting member 7 even if the mounting member 7 is made of synthetic resin or metal.

FIG. 7 shows another embodiment of the present invention, in which the mounting member 7 is composed of a mounting member main body 7a and a metal fixing plate 12 fixed to the mounting member main body 7a, and the fixing plate 12 has a mounting pin. 6 is provided in a protruding manner, and the mounting pin 6 is inserted through the slide hole 5, bent and slidably locked.

In this way, the mounting member 7 is composed of the mounting member main body 7a and the metal fixing plate 12 fixed to the mounting member main body 7a. Since the hinge is formed by inserting the mounting pin 6 through the slide hole 5, bending it, and slidably locking it, the mounting pin 6 protruding from the fixed plate 12 is inserted into the slide hole 5, bent, and locked. 1
Since it is possible to attach the hinge 1 to the mounting member body 7a, it is extremely easy to attach the hinge, and since there is no need to insert the mounting pin 6 into the mounting member 7, there is no risk of damaging the mounting member main body 7a, and the hinge 1 can be directly connected to the mounting member main body 7a. Because it does not make sliding contact with 7a,
This has the effect that there is no risk of damaging it.

8 and 10 further show another embodiment of the present invention, in which the mounting member 7 consists of a mounting member main body 7a and a fixing plate 12 fixed to the mounting member main body 7a.
The locking pin 6 is provided with a screw hole 13 in the direction of both ends thereof, and the screw screw 13 is provided so as to be screwable into the screw hole 14 of the fixing plate 12.

With this configuration, the butterfly plate body 2 of the hinge 1 and the mounting member main body 7a of the mounting member 7 do not come into direct sliding contact, so there is no risk of damage. It has the advantage that it can be easily installed by simply screwing it into 14.

FIG. 9 shows another embodiment of the present invention, in which the mounting member 7
A slide hole 5 is bored in the mounting plate 15 fixed to the hinge 1, a locking pin 6 is provided protruding from the butterfly plate body 2 of the hinge 1, and the locking pin 6 is inserted into the slide hole 5 to bend and slide. It is movably locked.

This has the effect that there is no need to drill a slide hole in the hinge.

Since the present invention is constructed as described above, the distance between the mounting members 7 attached to the two freely openable and closable butterfly plates 2 of the hinge 1 can be expanded and contracted as desired. Even when three pieces are connected, there is an effect that they can be folded inward and folded into three pieces at will.

Since the hinge 1 is attached to the mounting member 7 by passing the locking pin 6 through the slide hole 5 bored in the butterfly plate body 2, the interval between the mounting members 7 attached to the hinge 1 can be adjusted using the mounting member 7. The advantage is that this can be easily done by pulling the two outwards or by pressing them inwardly together.

Furthermore, this invention allows the interval between folded picture frames to be adjusted according to the wall thickness of the folded picture frame, allowing the three picture frames to be folded perfectly into three layers as if they were one. There is.

In addition, since the slide holes are formed obliquely and parallel to both ends, if you want to open the gap between the connected picture frames, you have to pull them outward with some force to open the gap, so three frames are connected. The advantage of this type of picture frame is that there is no fear that the distance between the frames will open up due to slight vibrations or when the frame is lifted by hand.

Since the structure is simple, it is easy to handle and can be provided at low cost.
