Abstract

The present invention is to allow a hinge connected to the center of a suction plate to be smoothly moved. Compared to an existing hinge that only can be moved in one direction, a ring is added to the hinge so that the hinge can rotate around the axis of the suction plate and thus can be moved in all directions on a spherical surface. Also, more various objects can be connected to a connection portion of the hinge to use and the objects can be more conveniently used.

Description

Spherical surface movement hinge connected to suction plate {SPHERICAL SURFACE MOVING HINGE CONNECTED WITH SUCTIONCUP}

The present invention relates to a structure of a hinge coupled to an adsorption plate, and is a technology for changing the structure of the hinge so that the movement of the hinge is smooth and useful.

The present invention relates to a hinge connected to the adsorption plate, and according to the use of the adsorption plate (patent 10-1112657) that has high adsorption power and can be attached to various materials, it can be attached if it is not very rough, such as wood or tiles beyond glass. There are many places. So, you can use pens, toothpaste, and cosmetic container lids on the screw connected to the central hinge of the suction plate. However, in order for the inserted object to be used smoothly, the inserted ring must be free to move.

An object of the present invention is to provide a smooth hinge structure when the suction plate and various articles are combined as described above.

In order to use the suction plate connection hinge smoothly, the structure must be able to combine various items, and when the combined items are pulled, the container can be easily separated from the support such as a wall or desk, but the suction plate itself must not fall. . You also need to be able to pull or insert items from various angles. In addition, it must be possible to move the position by removing the suction plate.

When using the hinge part on the side hole of the suction plate, as in Patent 10-1005585 (Holder that can be selectively accommodated) or Patent (10-0913060 Fig. 1), there are many inconvenient points to use because it does not rotate freely.

In addition, (Patent 10-0913060 Fig. 5, 180) In a hinge structure that is retracted upwards like a toothpaste hanger, it is difficult to insert the coil spring, and there is a case where it is pierced at the end, and it is difficult to match the elastic force of the spring (Fig. 6).

Depending on the use of the above items, the position of the connection screw of the hinge must be underneath the connection screw (referred to as 180 degrees) before connecting the lid, and the container should be hung naturally when the lid is engaged (angle 90 degrees). ), when the container is removed, the lid must face the front (angle 0 degrees).

This is because it is easy to insert.

On the other hand, since pens are used on a desk, they have a different angle depending on the location of the person writing. Therefore, it must be kept in the pulled position at any angle so that it can be easily inserted when reinserted.

In addition, when a smartphone or a mirror is combined with the suction plate hinge and used at a desk, it is difficult to maintain the angle of the article because it is inclined because it weighs more than pens.

In this case, discontinuous hinge movement with strong frictional force is required.

In order to solve the above problems, a pipe-shaped ring that can be rotated by being inserted into the center of the suction plate was introduced.

The suction plate as shown in Fig. 1 is fitted with a hinge composed of a ring, so that even if the container is inserted or pulled at any angle, it supports the force in the center direction, so that it is stably inserted and removed from the lid.

When you pull the container out of the lid and put it back on the lid, it is convenient to keep the position when it is pulled. To do this, the hinge should not be tilted by the weight of the lid. In order to keep the hinge in place, a friction member (rubber, silicone, etc.) 124 for increasing friction was added to the side of the hinge to prevent the lid from flowing down from the pulled position.

In addition, if the ring material inserted into the central column groove of the suction plate is cut with a double rubber material and an air hose molded with a fiber structure in the middle, it can have tough toughness and strong friction. When the above material is used, it is not damaged by the pulling force of the hinge rotation shaft, and it has an appropriate frictional force so that movement does not occur due to the self-weight of the hinge.

The method of giving a friction member (Fig. 1, 124) having frictional force on the side surface allows continuous angular movement.

The structure capable of simultaneously performing the frictional role and the ring role (FIG. 4) as described above enables the same function to be performed by the uneven hole elastic member like the injected ring (FIG. 2,200) using a plastic injection product.

When the projections and convexities 201 are formed on the upper and lower frames as shown in (Fig. 2) on the injection product, the angled hinge shaft 221 rotates and stops at the concave portion, and a strong force is required to go beyond the convex portion. It is done with.

Therefore, movement occurs intermittently.

In addition, in a smooth hole without irregularities, when the hinge shaft is forcibly inserted, it plays the same role as (Fig. 1) by the action of frictional force.

If the location where the toothpaste is inserted like a lid is constant like a wall, the movement of the hinge needs to be simple. To do this, by inserting the coil spring 421 between the hinges (Fig. 4, 421), if the end of the hinge is in the shape of a rectangle and the long side, that is, the width of the spring is spread out, it will return to its original position until it is erected at 90 degrees. The elastic force to turn is generated, and it is always placed on the wall. That is, the 3-position 0 degree, 90 degree, 180 degree, Roman hinge is placed.

Plastics with a thin thickness (less than 1mm) such as toothpaste lids or glue lids tend to be easily loosened from the connecting screw by repeated use. This is because the width of the plastic caught on the connecting screw is narrow. In order to prevent such loosening, if the protrusion is formed in the clockwise direction (Fig. 3, 324), the right screw direction slides and locks well, but the reverse direction is caught by the edge of the end, so that it cannot be released during the opening and closing process, and strongly reverse rotation is given. , It is released only when a force exceeding the holding force is applied.

In (Fig. 3), injection was performed to play the same role as the spring in (Fig. 4), so that the movement occurs by 90 degrees by the movement of the angled hinge between the rectangular holes.

(Fig. 4) plays the same role as (Fig. 3), but since there is no ring, there is no rotation, and only vertical movement occurs.

The purpose of the suction plate is to support or fix objects. If you use it for the purpose, it will reduce a lot of hassle. Using something with a lid comes with the inconvenience of always using both hands. For example, in the case of the lid of the toothpaste that is most frequently encountered and the sign pen used in public places, it is possible to prevent the inconvenience of opening and closing the lid of the pen in the process of waiting for many people. In addition, it is a must-have item if it is unavoidable to use one hand. In order to relieve the user's discomfort as described above, the structure of the hinge has been improved to make the use of a pen or container more convenient.

In addition, items that must be maintained at a certain angle, such as looking at a smartphone placed on a desk, a hand mirror, or a portable hand fan, are useful for keeping a certain angle.

(Fig. 1) shows a hinge with friction that is mainly used for pen holders. The suction plate 110 and the rotary connection ring 100 are shown in a separated state. The upper side of the ring insertion part 112 integrally molded with the suction plate 110 has an arrowhead-shaped detachment bump 116, and the inner side is the suction plate 110 having a separation prevention pin insertion part 114 formed therein, and is rotated. It has a flexible material into which the ring 100 can be inserted, and the bending hinge 120 is fitted into the holes 112 on both sides of the rotation connection ring 100. The bending hinge 120 has a connecting screw 122, and the soft cover 126 is inserted into the central part of the connecting screw 122 so that the contents of the container do not leak out when the container lid is coupled, and When there is no container, it acts as a protective cap to prevent injuries in contact.

The bending hinge 120 may rotate around the hinge insertion hole 102 back and forth. However, if there is too much friction, the bending hinge 120 cannot maintain its position. In order to prevent this, the friction member 124 is inserted into the ends of the bent hinges 120 on both sides and zoomed to maintain the initial state of being placed.

(Fig. 2) is a structure in which the structure of the rotating link 100 described in Fig. 1 is made simpler by using an extruded product and the strength of friction is increased.

In the structure of (Fig. 1), when an article that cannot support the bending hinge 120 only with the friction member 124 is combined, the friction is made stronger and a structure that holds the position.

The uneven hole elastic ring 200 is an undercut method used in an injection mold, and has elasticity by applying a method of forming holes only with upper and lower cores without sliding pins entering from the side to form holes.

The upper elastic ring 202 and the lower elastic ring 204 are formed by the upper and lower cores to form the hole irregularities 201, and the bent hinge end 221 is inserted into the hole so that the hinge end is not thick but wide When placed vertically, the upper elastic ring 202 and the lower elastic ring 204 have a strong frictional force while being sandwiched between the irregularities of the upper elastic ring 202 and the lower elastic ring 204, and the hinge end rotates so that the left and right elastic walls ( 203) has a frictional force.

(Fig. 3) is a hole irregularities 201 of (Fig. 2) made in the shape of a right-angled square, and is intended to be used when the position where the lid is placed like a toothpaste lid is always constant.

The square hole elastic ring 300 is a plastic injection product in which the ring upper part 302 and the ring lower part 304 are injected up and down to have elasticity, and the flat hinge 320 is sandwiched between them, and the hinge end 326 This rotation generates a pressing force between the upper ring portion 302 and the lower ring portion 304, and the width direction of the hinge end is erected at 90 degrees, so that it tries to return to its original position until no sliding occurs.

When the container lid 440 connected to the connection screw 322 is pulled, the angle is approximately 45 degrees, and the lid is opened and rotated to a position of 0 degrees, that is, upwards of the adsorption plate. At this time, the hook 541 of the lid is placed in a visible state.

When the container is inserted into the lid again, the hinge ring 320 is erected at 90 degrees between the upper ring 302 and the lower ring 304 by the weight of the container.

Since the thickness of the toothpaste lid is thinner and wider than that of pens, it tends to be easily loosened from the connection screw 322. So to prevent this

The one-way protrusion 324 is formed around the connecting screw 322 of the flat hinge 320 to prevent loosening.

(Fig. 4) is an example of the application of Fig. 3, and a tension spring 421 is used instead of an elastic ring.

By being fitted to the end of the flat hinge 420, the elastic ring 300 serves as a substitute.

(Fig. 5) is an exploded perspective view of Fig. 4, in which a hinge connection hole 512 and a separation prevention hole 514 are formed in the suction plate 510, and the tension spring 521 is inserted into the suction plate 510. Right, while inserting the end of the flat hinge 520 between the tension springs 521, at the same time, it is inserted into the hinge connection hole 512. In addition, by inserting the separation prevention pin 530, the flat hinge 520 is prevented from slipping out.

(Fig. 6) is a conventional technique to create a restoring force of the flat hinge 620 to the torsion spring 624. In this case, when the elastic force of the torsion spring is strong, as the contents of the container are used, the container is lifted at some point and has a shape that does not naturally hang on the wall. Another problem may occur when the torsion spring 624 is stabbed at the end.

(Fig. 7) shows a structure that is difficult to use while pulling in various directions because the hinge connection hole 712 formed in the suction plate 710 is fixed as a conventional pen holder, so that the bending hinge 720 moves only before and after. I had.

(Figure 8) shows an example of implementing a hinge structure of various shapes, it can be used by making a variety of hinges, such as a bar circle 810, a bar square 820, a plate circle 830, and the like.

(Fig. 9) has the same function as (Fig. 1), but the assembly method is different. When the insert bolt 912 is attached to the suction plate 910, the bending hinge 920 is

It is inserted into the rotational connection ring 900, and the rotational connection ring 900 prevents separation by inserting the ring insertion nut 930 into the insert bolt 912 and serves as a rotating central axis.

The use has been described based on the above drawings.
