[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a handle used for a door, a bag, a case or the like of an automobile or a building, and a manufacturing method thereof.
[0002]
[Prior art]
Conventionally, many types of handles are used in automobiles, houses, and the like. Most of them are cores made of hard resin, metal, etc., coated with a thermoplastic elastomer resin, or the metal as it is or wooden. When it is coated, it is often molded with a synthetic resin or the like. Many types have been proposed that have been extensively devised for grip feel and the like.
[0003]
However, most of the conventional grips or grips are manufactured in the form of a mold over the entire circumference of the grip (see, for example, Patent Document 1). The touch of the finger is delicate, and it is easier to grip when the grip part is slightly deformed by pressing the finger and has a soft image. Metals (see, for example, Patent Document 2) are designed to prevent charging because they are charged, but they also have a hard feeling because they are metal, and have a hard and cold feel.
[0004]
In addition, wooden items can be made into a handle that has grain and is naturally oriented and visually soft, but it is actually only used in homes. Complex shapes cannot be made, and production problems also arise as the number increases. Metal and wooden objects have a poor soft feel when grasping. Recently, an antibacterial treatment has also been proposed (see, for example, Patent Document 3). This is especially used for toilet knobs.
[0005]
Recently, synthetic resin-made ones have been applied to bags and the like due to the fact that they can be formed in complex shapes and have a high degree of freedom in design, and handles that can make the grip part flexible by mold manufacture have become widespread. The synthetic resin handle is a synthetic resin made by providing a concave portion so that the entire handle main body can be easily grasped, or an elastic handle that is covered with an elastomer or the like. However, there is no handle that presses only the fingertip and is partially deformed to obtain a delicate soft feel of the fingertip, and such a handle is desired.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail. The handle of the present invention is not limited in shape. As a handle in a form that can be attached to a mating door or the like, the form will be described based on the example of the figure. FIG. 1 is an external view showing the overall structure of the handle of the present invention. FIG. 2 is a cross-sectional view taken along line XX in FIG. FIG. 3 is a cross-sectional view showing a configuration of a divided part part stage.
[0014]
This handle is used for building doors, travel cases, and the like. The handle includes a handle main body 1 (body) that is the main body of the outer shape, an elastic body 2 configured to have a soft feel at a part of the grip of the handle, that is, a fingertip contact portion, and the elastic body 2 from the inside. It is comprised from the restoring body 3 comprised so that it might press. The handle body 1 is formed by injection molding a hard resin.
[0015]
The hard resin is, for example, a polyester resin. The handle main body 1 of the embodiment has a U-shaped cross-sectional shape, and is provided with a male screw 1a for attaching to the mating member at the end. When the handle body 1 is attached to a door or the like, the male screw 1a is inserted into a hole formed in the mating door, and is clamped and fixed with a nut or the like. Handle body 1 is divided in parts formed form stage is formed form as a two handle body parts.
[0016]
As shown in FIG. 1, the handle main body 1 is divided into an inner side and an outer side, and an inner handle main body part is an inner handle main body 1b and an outer handle main body part is an outer handle main body 1c. The male screw 1a is provided on the inner handle main body 1b. The inner handle body 1b and the outer handle body 1c are integrated together to form the handle body 1. Each of the divided inner handle main body 1b and outer handle main body 1c is mold-produced and can be mass-produced.
[0017]
The mating surfaces 1d and 1e are provided with uneven portions for alignment, the mating surface 1d of the inner handle body 1b is provided with a convex portion 1f, and the mating surface 1e of the outer handle body 1c is provided with a concave portion. 1 g is provided, and when the two are combined, the uneven portion is positioned and united. In this positioning configuration, the unevenness may be reversed, or the mating surface itself may be formed in a shape that can be positioned.
[0018]
Further, when the inner handle body 1b and the outer handle body 1c are combined to form the handle body 1, the interior is in a space state. The fact that the interior is a space allows various functions to be added to the interior. Moreover, although the figure of an Example is the straight shape in the external shape of the handle main body 1, the shape which provided the unevenness | corrugation so that it might be easy to grip may be sufficient. The fingertip contact portion of one inner handle main body 1b is in a state where a hole 1h is provided. The outer handle main body 1c is provided with a partition 1i, and a part of the main body is raised in a convex shape. Each of the divided inner handle main body 1b and outer handle main body 1c is assembled with the elastic body 2 and the restoring body 3 which are the features of the present invention at the component stage before being combined.
[0019]
The elastic body 2 is attached to the hole 1h described above on the inner handle main body 1b. In this attachment, a concave portion provided in advance in the elastic body 2 is fitted into the edge of the hole. After installation, it has a structure that cannot be removed under normal use. The elastic body 2 is a urethane, amide, polyester, olefin, or styrene thermoplastic elastomer. The elastic body 2 may be attached by fitting it in the shape of the hole 1h in advance into the hole 1h of the inner handle main body 1b and fixing it with an adhesive or by heat sealing.
[0020]
In the case of heat fusion, it is firmly fixed. However, it is necessary to select a material that fuses the hard resin constituting the handle body 1 and the above-mentioned elastomer well. If the close contact between the elastic body 2 and the inner handle main body 1b is good, the elastic body 2 may be simply fitted into the hole 1h. The hardness of the elastomer which is the elastic body 2 is 20 to 80 (JIS A DURO hardness). Moreover, the thickness of the elastomer of the part which elastically deforms the fingertip contact portion is 0.5 to 8 mm, preferably 0.5 to 2 mm.
[0021]
On the inner side of the outer handle main body 1c attached to face the inner handle main body 1b, a convex portion of the partition 1i is provided with a peripheral edge. A restoring body 3 is attached to the inside of the partition 1i that forms the periphery. The restoring body 3 is for pushing the pressed elastic body 2 back to the original position. The restoring body 3 is attached so as to face the elastic body 2 described above, and is in contact with the elastic body 2 when the inner handle main body 1b and the outer handle main body 1c are combined.
[0022]
When the elastic body 2 is pressed by the fingertip and retracted into the handle body 1 by elastic deformation, the restoring body 3 is also pressed and compressed in a swelled state. When the fingertip is released and the gripping state of the handle is released, the elastic body 2 returns to the original state, but the restoring body 3 also elastically deforms in cooperation and presses the elastic body 2 to restore the original position.
[0023]
In particular, when the elastic body 2 is thin, the elastic body 2 is forced to protrude outward, and it is effective to restore it. The restoration body 3 may be, for example, a polyurethane resin, a polypropylene resin, a polyethylene resin, a polystyrene resin or the like as a cushion body, may be an air pillow, and has a high resilience. desirable. A coil spring may be incorporated. The restoring body 3 is fitted as it is inside the partition 1i forming the peripheral edge or attached with an adhesive.
[0024]
Thus, the inner handle main body 1b and the outer handle main body 1c to which the elastic body 2 and the restoring body 3 are attached are combined at the component stage. Each alignment surface 1d, 1e is provided with a convex portion 1f and a concave portion 1g for alignment, and is bonded by ultrasonic welding after alignment. The alignment uneven part is not limited and may be reversed. The shape of the mating surface may be a specific shape that can be aligned. This handle is not expensive and can be replaced with another handle when trouble occurs. Therefore, the handle is not disassembled and repaired after it is combined.
[0025]
Although the present invention has been described on the premise that it is most effective to divide into two, even if the handle body is integral from the beginning, after the restoration body is inserted and fixed from the hole before attaching the elastic body, Although the structure having the same function as described above is possible by attaching and fixing the elastic body in this hole, there are disadvantages that the molding method is complicated and there are too many manufacturing constraints and the reliability is poor. The division is easier to manufacture, and the configuration of multiple functions is easier. Furthermore, by making the handle body into a two-part molded product, a complicated shape can be manufactured at low cost, and an excellent handle can be manufactured in terms of design. The molded product can be mass-produced.
[0026]
As described above, the handle of the present invention emphasizes the grip feeling of the fingertip, but it is possible to add the function to the inside of the handle body as described above by utilizing this feature. For example, if a sensor is attached between the restoring body 2 and the outer handle main body 1c, it is possible to take out a signal obtained by grasping the handle to the outside. For example, in the case of a door at the entrance of a building, it is possible to detect at a position away from the visitor's confirmation or crime prevention.
[0027]
In addition, the door with an open / close lock requires a design ingenuity. However, if the hook is formed in a cylindrical shape through a lever or the like so that it can be connected to the door, the elastic body 2 is provided. The door can be opened and closed by pressing the door. Making the handle partly elastically deformable is also effective in terms of developing the function in this way in addition to the soft touch.
[0028]
【The invention's effect】
According to the present invention, the fingertip is configured to press the elastic body when the handle is gripped, and the handle has a soft feel. In addition, since the handle body is a molded product having a divided structure, it is possible to manufacture a complicated design structure and to achieve high productivity. Furthermore, it became the structure which can provide many functions inside a handle.
