Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a handle used for doors, bags, cases, and the like of automobiles, buildings, and the like, and a method of manufacturing the same.
[0002]
[Prior art]
Conventionally, many types of handles have been used in automobiles, houses, and the like. Most of them are made of a core body such as a hard resin or a metal covered with a thermoplastic elastomer resin, or a metal as it is, or a wood or the like. When it is coated, it is often formed of a synthetic resin or the like. Many types have been proposed that have been devised in a wide variety of ways such as grip feel.
[0003]
However, most of the conventional handles or grips have a form in which the entire grip portion is manufactured around the entire periphery of the handle (for example, see Patent Document 1). The feeling of the finger is delicate, and it is easier to grasp when the grip portion is slightly deformed by pressing of the finger, and has a soft image. Metallic ones (for example, see Patent Document 2) prevent charging by charging, but also have a hard feeling due to the metal, and have a hard and cold feeling.
[0004]
A wooden handle can be used as a handle which has a grain and is natural-oriented and has a soft feeling visually, but is actually used only in a house or the like. A complex shape cannot be obtained, and when the number increases, production problems arise. Metal and wooden objects have a poor soft feel when gripping. Recently, antibacterial treatments have been proposed (for example, see Patent Document 3). This is especially used for toilet knobs.
[0005]
Recently, synthetic resin products are applied to bags and the like because of their ability to produce complicated shapes and a large degree of design freedom. This synthetic resin handle is made of synthetic resin by providing a concave portion so that the entire handle body can be easily grasped, or a handle having elasticity by covering the surface with an elastomer or the like. However, there is no handle that presses only the fingertip and partially deforms the fingertip to give a delicate soft feel to the fingertip, and such a handle is desired.

[0013]
BEST MODE FOR CARRYING OUT 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 that can be attached to a mating door or the like, the form will be described based on an example in the drawing. FIG. 1 is an external view showing the entire configuration of the handle of the present invention. FIG. 2 is a cross-sectional view taken along line XX of FIG. FIG. 3 is a cross-sectional view showing a configuration of a divided handle at a component stage.
[0014]
This handle is used for a door of a building, a travel case, and the like. The handle is composed of a handle body 1 (body) serving as a main body of the outer shape, an elastic body 2 configured to have a soft touch at a part of the grip portion of the handle, that is, a fingertip contact section, and the elastic body 2 from the inside. And a restoring body 3 configured to be pressed. 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 section, and is provided with an external thread 1a at an end for attaching to a mating member. When the handle main body 1 is attached to a door or the like, the male screw 1a is inserted into a hole formed in a mating door, and is held and fixed by a nut or the like. The handle main body 1 is divided at the part molding stage and molded as two handle main body parts.
[0016]
The handle main body 1 is divided into an inner side and an outer side as shown in FIG. 1, and the inner handle main body part is an inner handle main body 1b, and the outer handle main body part is an outer handle main body 1c. The external thread 1a is provided on the inner handle 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 manufactured in a mold and can be mass-produced.
[0017]
Each of the mating surfaces 1d and 1e is provided with an uneven portion for alignment, a mating surface 1d of the inner handle body 1b is provided with a convex portion 1f, and a mating surface 1e of the outer handle body 1c is formed with a concave portion. 1g is provided, and when both are combined, the concave and convex portions are positioned and united. In this positioning configuration, the unevenness may be reversed, and the positioning configuration may be formed in a shape that can position the mating surface itself.
[0018]
When the inner handle body 1b and the outer handle body 1c are combined to form the handle body 1, the inside is in a spatial state. When the inside is a space, various functions can be added to the inside. In addition, although the figure of the embodiment is straight in the outer shape of the handle body 1, it may be a shape having irregularities so as to be easy to grasp. The fingertip contact portion of one inner handle main body 1b is in a state where a hole 1h is provided. A partition 1i is provided inside the outer handle main body 1c, 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 restoration body 3 which is a feature of the present invention, at a component stage before being combined.
[0019]
The elastic body 2 is attached to the hole 1h described above on the inner handle 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 will not come off under normal use conditions. The elastic body 2 is a urethane-based, amide-based, polyester-based, olefin-based, or styrene-based thermoplastic elastomer. The attachment of the elastic body 2 may be carried out by molding a preformed shape of the hole 1h into the hole 1h of the inner handle body 1b and fixing it with an adhesive or by heat fusion.
[0020]
In the case of heat fusion, firm fixation is required, but it is necessary to select a hard resin that forms the handle body 1 and the above-mentioned elastomer that is well fused. If the elastic body 2 and the inner handle main body 1b have good adhesion, the elastic body 2 may be simply fitted into the hole 1h. The hardness of the elastomer as the elastic body 2 is 20 to 80 (JIS A DURO hardness). Further, the thickness of the elastomer at the portion of the fingertip contact portion where the elastic deformation occurs is 0.5 to 8 mm, preferably 0.5 to 2 mm.
[0021]
Inside the outer handle body 1c attached to the inner handle body 1b, a convex portion of the partition 1i is provided so as to form a peripheral edge. The restoration body 3 is attached inside the partition 1i that forms the periphery. The restoration body 3 is for pushing the pressed elastic body 2 back to the original position. The restoration 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 body 1b and the outer handle body 1c are combined.
[0022]
When the elastic body 2 is pressed by a fingertip and retracted into the handle main body 1 by elastic deformation, the restoration body 3 is also pressed and compressed in an expanded state. When the fingertip is released and the gripping state of the handle is released, the elastic body 2 returns to its 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 forcibly extended outward, and it is effective to restore the elastic body 2. The restoration body 3 may be a foam body resin such as a polyurethane-based, polypropylene-based, polyethylene-based, or polystyrene-based cushion body, or may be an air pillow. desirable. Further, a coil spring may be incorporated. This restored body 3 is fitted as it is inside the above-mentioned peripheral partition 1i or attached with an adhesive.
[0024]
In this way, the inner handle main body 1b and the outer handle main body 1c to which the elastic body 2 and the restoration body 3 are attached are assembled at the component stage. Each of the mating surfaces 1d and 1e is provided with a convex portion 1f and a concave portion 1g for positioning, and is bonded by ultrasonic welding after positioning. The positioning uneven portion is not limited, and may be reversed. Further, the shape of the mating surface may be a specific shape that allows position alignment. This handle is not expensive, and if a trouble occurs, it may be replaced by another handle. Therefore, after the uniting, the handle is not disassembled and repaired.
[0025]
Although the present invention has been described on the assumption that it is most effective to divide into two, even if the handle body is integral from the beginning, after inserting and restoring the restoration body from the hole before attaching the elastic body, The same function as described above is possible by attaching and fixing the elastic body in this hole, but it has the disadvantage that the molding method is complicated and the manufacturing has too many restrictions and the reliability is poor. The division is easier to manufacture and the configuration for multi-functionality is easier. Further, since the handle main body is formed into a two-part molded product, a complicated shape can be manufactured at low cost, and excellent handle manufacture can be achieved in terms of design. Also, molded products can be mass-produced.
[0026]
As described above, the handle of the present invention emphasizes the feeling of grasping the fingertip, but it is possible to add a function as described above to the inside of the handle body by utilizing this feature. For example, if a sensor is attached between the restoration body 2 and the outer handle main body 1c, it is possible to extract a signal generated by gripping the handle to the outside. For example, in the case of a door at the entrance of a building, it is possible to confirm a visitor or to detect a person at a position distant from crime prevention.
[0027]
Further, in the case of a door having an opening / closing lock, it is necessary to devise a design. However, if a hook is provided inside the handle, for example, by making a screw into a tubular shape via a lever or the like so that it can be connected to the door, the elastic body 2 By pressing, a door that can be unlocked and unlocked by the handle can also be provided. The partial elastic deformation of the handle is effective not only in the soft touch but also in the function development in this way.
[0028]
【The invention's effect】
ADVANTAGE OF THE INVENTION According to this invention, it is the structure which a fingertip presses an elastic body when gripping a handle, and it became the handle which can obtain soft feeling. In addition, since the handle body is a molded product having a divided configuration, a complicated design configuration can be manufactured, and high productivity is achieved. Further, more functions can be provided inside the handle.
