Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an object having a handle. For example, the present invention relates to an object having a handle that can be used for an armrest or the like having a handle on the indoor side of an automobile door.

[0002]

2. Description of the Related Art Pullers are formed on doors such as sliding doors and sliding doors, drawers such as closets and desks, and the like.
The handle is opened and closed by putting a fingertip on the handle and pulling the handle.

[0003] In automobiles, pullers are also used. That is, when closing the door from inside the car,
This puller is used. The puller on the door of the car is mounted on an armrest protruding inside the car. Specifically, a recessed space is opened on the upper surface of the armrest, and this space is used as an operation space for a fingertip.

Usually, such a pull is formed by a door trim pull member. Specifically, the puller is formed of an armrest having an original opening, and a door trim puller member inserted into the original opening of the armrest and forming an operation space. Here, the door trim puller member that partitions the operation space of the puller is shown in FIGS. 8 and 9. Here, FIG. 9 shows A-
The cross section along line A is shown. Door trim puller member 61
As can be seen from FIG. 9 showing the cross section, the wall surface defining the operation space was formed so as to extend substantially vertically.

This door trim puller member has a problem that when used as a puller, the fingertip inserted into the operation space slides and it is difficult to handle. further,
As shown in FIG.
1 and the outer mold 75 are used to mold the resin, so that the side wall surface is inclined so as to increase the cross-sectional area from the bottom surface toward the opening side in order to remove the inner mold. I was Due to the inclination of the side surface, when used as a pull handle, it becomes more difficult to handle.

Another example of a door trim puller member used for a puller formed on an armrest is shown in FIGS. 11 and 12, for example. The door trim puller member 62 is formed in an undercut shape so that the side wall surface 65 with which the fingertip contacts is widened on the bottom side. Here, FIG. 12 shows a cross section taken along line BB of FIG. 11 so that the undercut shape of the side wall surface 65 of the door trim puller member 62 can be seen. Since the side wall surface 65 is formed in an undercut shape, the puller using the door trim puller member is more likely to be touched by a fingertip, thereby improving usability.

However, even in the door trim puller member 62 having the undercut, the depth of the undercut cannot be said to be sufficient. That is, there is a limit to the depth of the undercut due to a manufacturing problem.

The door trim puller member is manufactured by molding a resin using a molding die including an inner die and an outer die 75. The inner trim portion 72 for forming the undercut portion is horizontally formed. After moving in the vertical direction, the inner mold portion 72 was pulled out of the door trim puller member through the opening. FIG. 13 shows a diagram when the inner mold portion is extracted.

That is, the above-mentioned limit of the depth of the undercut is caused by the movement of the inner mold portion 72. That is, the size of the opening of the operation space of the door trim puller member 62 is limited, and if the amount of undercut is increased, the inner mold portion 72 cannot pass through the opening, and as a result, the inner mold portion is It could not be pulled out of the pull member. Also, when extracting the inner mold part,
Since the slide in the horizontal direction is required, there is a problem that the manufacturing cost is increased.

[0010]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide an object having a puller having an undercut portion having a sufficient depth.

[0011]

Means for Solving the Problems In order to solve the above-mentioned problems, the present inventors have repeatedly studied an object having a pull, and found that an object having an undercut portion of the operation space and an opening of the operation space. It has been found that an object having a portion and having a portion corresponding to the undercut portion is missing, and an object having a pull to solve the above problem can be provided by attaching the box to the object.

That is, the object having the pull of the present invention is:
An object having an opening into which a fingertip except for the thumb is inserted and a puller that defines an operation space that is undercut with respect to the opening that comes into contact with the fingertip in a state where the inserted fingertip is bent inward. A faceplate member having a large original opening, a first handle portion adjacent to the original opening and defining at least a part of an undercut portion of the operation space, and a face plate member constituting at least a part of an object; and an opening having an opening And a box bottom part, which is formed integrally with the opening and has a side bottom part having a missing part without an undercut part, inserted into the original opening, and attached to the face plate member, I do.

In the object having the pull of the present invention, the depth of the undercut can be freely designed by forming at least a part of the undercut portion on the face plate member forming a part of the object. Further, since it is not necessary to form an undercut in the box portion, it is possible to suppress an increase in cost required for manufacturing the box portion.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION An object having a puller according to the present invention has an undercut with respect to an opening into which a fingertip except a thumb is inserted and an opening which abuts against the fingertip with the inserted fingertip bent inward. Is an object that partitions the operation space. That is, since the object having the puller of the present invention has an operation space that is undercut with respect to the opening, when the puller is pulled, it is easy to grasp with the fingertip, and the fingertip slips. It is held down, making it easier for the object to be started by the puller.

The object having the pull of the present invention has a face plate member and a box portion.

The face plate member has an original opening which is larger than the opening, and a first pulling portion which is adjacent to the original opening and defines at least a part of an undercut portion of the operation space, and constitutes at least a part of the object. It is a member that does.

The original opening is formed larger than the opening. That is, in the object having the handle of the present invention, the box portion inserted into the original opening forms an opening of the operation space, and thus the original opening is formed larger than the opening so that the box portion can be inserted. In addition, since the original opening is formed to be larger than the opening, the formation of the first pull portion becomes easy. That is, by forming the original opening large, a space for moving the mold when forming the first pull portion is obtained.

Further, the original opening need not be located on the same plane. That is, the original opening only needs to be formed so that the opening of the operation space can be formed when the box body is mounted on the face plate member, and is formed so as not to hinder the insertion of the box body forming the opening. It should just be done.

The first pull portion is a member adjacent to the original opening and defining at least a part of an undercut portion of the operation space. That is, the first pull portion is a member that partitions at least a part of the undercut portion of the operation space formed when the box body portion is mounted on the face plate member. Here, at least a part of the undercut portion of the operation space defined by the first pulling portion indicates a portion including a part of the side bottom surface defining the bulging portion of the operation space.

The face plate member is a member constituting at least a part of the object. For this reason, the movement of the face plate member forming a part of the object is facilitated by the first puller part constituting at least a part of the undercut part of the operation space. That is, since the object itself moved by the puller receives the force from the fingertip directly by the first puller portion, the loss of the force is less likely to occur.

The box body is composed of an opening having an opening and a side bottom formed integrally with the opening and having a defective portion having no undercut portion, and is inserted into the original opening and attached to the face plate member. Member.

The opening forms an opening of the operation space. That is, the opening forms an opening into which the fingertip of the puller is inserted. This opening is formed smaller than the original opening. Here, the shape of the opening is not particularly limited, and may be not only a square shape but also a circular shape.

The side bottom portion is a member formed integrally with the opening and having a defective portion without an undercut portion. That is, the lack of the portion where the side bottom is undercut indicates that the box portion having the side bottom has no undercut. This eliminates the need for complicated processing required when forming an undercut portion in the box body.

Here, the shape of the side bottom other than the defective portion is not particularly limited as long as the shape is other than the undercut shape. As the shape of the measurement unit, for example, a square shape in which a portion corresponding to a missing portion is missing can be given.

The box body is inserted into the original opening and mounted on the face plate member. At this time, the box body is mounted such that the missing portion is covered by the first pull portion of the face plate member. An operation space having an undercut is formed by attaching the box body to the face plate member.

In the object having the pull of the present invention, the face plate member forms an undercut portion of the operation space of the pull,
It is not necessary to form an undercut portion in the box portion. As a result, there is no need to perform complicated processing when forming the box body portion, and the cost required for manufacturing can be suppressed.

The box body preferably has a surface portion including an opening and constituting a part of the surface of the face plate member. That is, since the original opening formed in the face plate member is formed larger than the opening of the box body portion, when the box body portion is attached to the face plate member, the gap between the opening of the original opening and the opening of the box body portion becomes larger. Gaps occur Therefore, since the surface portion covers the gap, the appearance of the object of the present invention is improved, and at the time of operation of the object, the finger does not fall outside the operation space, and the safety at the time of operation is also improved.

Preferably, the surface portion has a fold that covers the first pull portion of the face plate member and forms the outer surface of the object. By having the folds, the object having the pull of the present invention can grasp the box body by sandwiching the folds and the first pull with the fingertip and the palm, thereby improving the operability of the pull. I do. In addition, by having the folds, it is possible to take a sufficient space for moving the mold when forming the shape of the undercut portion of the first pull portion of the face plate member.

The face plate member preferably has a holding portion for holding a part of the outer peripheral surface of the side bottom surface of the box body portion in contact therewith. With the holding portion, when the box body is mounted on the face plate member, the box body is held without displacement. Also,
When the box body is mounted, the box body is guided so as to be arranged at a predetermined position.

It is preferable that the object having the pull of the present invention has fixing means for fixing the box body to the face plate member. That is, by having the fixing means, the box body is fixed to the face plate member, and the force applied to the box body when used as a pull is transmitted to the face plate member and the object without loss. As the fixing means, any means can be used as long as it can fix the box body portion and the face plate member, and examples thereof include means such as bonding and screwing.

In the object having the pull of the present invention, it is preferable that the face plate member and the box body are formed of resin. Here, the type of the resin forming the box is not particularly limited, and a normal resin can be used. Examples of this resin include resins such as ABS resin and PP resin.

When the face plate member and the box portion are formed of resin, a usual resin molding method can be used. Examples of the molding method include injection molding and reaction injection molding.

[0033] The box portion includes a mold portion for forming a missing portion,
It is preferable to mold using a mold having an opening and a mold portion for molding the inner peripheral surface. In other words, the box body can be easily formed by forming the mold with the mold for molding the opening of the inner mold and the mold for molding the missing part. At this time, it is preferable that the two mold portions are relatively moved in the directions facing each other and are extracted from the box body portion. This makes it possible to suppress the increase in the manufacturing cost without complicating the movement of the mold portion when extracting the mold portion from the box body portion after molding the box body portion.

In the object having the pull of the present invention, the depth of the undercut can be freely designed by forming at least a part of the undercut portion on the face plate member forming a part of the object. Further, since it is not necessary to form an undercut in the box portion, it is possible to suppress an increase in cost required for manufacturing the box portion.

The object having the pull of the present invention is useful for using the space defined by the undercut shape as the operation space of the pull, and is particularly used as the pull installed on the armrest of the door of the automobile. Is preferred.
Specifically, an armrest protruding inwardly of the vehicle is formed by a puller including an armrest portion protruding inside the door of the automobile and a box body mounted on the armrest portion. The original opening and the first pull portion are formed in the armrest portion, the opening portion and the side bottom portion are formed in the box body portion, and the operation space to be undercut is defined by inserting the box body portion into the armrest portion. A puller can be formed. Further, at this time, the first pull portion that partitions a part of the undercut portion is formed in a state where the first pull portion is located in a protruding tip direction of the armrest portion.
