The door handle rotating tool according to the embodiment of the present invention will be described using door handle rotating tools 1 and 1A of Examples 1 and 2. Hereinafter, the door handle rotating tools 1 and 1A will also be simply referred to as rotating tools 1 and 1A.

Example 1
Fig. 1 is a front view showing a rotating tool 1. In the following description, the up, down, left, and right directions are defined by arrows in Fig. 1. The front is the front of the page, and the rear is the back of the page. The up, down, left, right, front, and back directions are defined for the convenience of description, and do not limit the usage posture of the rotating tool 1, etc.
FIG. 2 is a top view of the turning tool 1, and FIG. 3 is a perspective view of the turning tool 1 as viewed from diagonally above and to the left of the front.

As shown in Figs. 1 to 3, the rotating tool 1 has an outer shape that is a flat rectangular parallelepiped that is long in the left-right direction and thin in the front-rear direction, and is formed symmetrically in the left-right direction and the front-rear direction.
The rotating tool 1 is formed by resin injection molding or by a three-dimensional printer.

The rotating tool 1 has a through hole 11 and an insertion portion 12 .
The insertion portion 12 is a rectangular recess that opens in the upper surface 1a and is long in the left-right direction, and is a bottomed portion that is hollowed out downward from the upper surface 1a.
As shown in FIG. 1, the depth of the insertion portion 12 is defined as a distance La carved out downward, which is about ⅓ of the vertical width of the rotating tool 1 from the upper surface 1a.
The rotating tool 1 has a through hole 11 formed in a portion lower than ⅓ position from the upper surface 1 a.
In other words, the rotating tool 1 has a flat shape with its longitudinal direction extending in the left-right direction as shown in Fig. 3, and the insertion portion 12 is formed on the top surface 1a, which is one of the side surfaces along the longitudinal direction. The through hole 11 is formed in a lower portion on the other side surface side of the insertion portion 12, so as to penetrate in the thickness direction, which is the front-rear direction.

Inside the insertion portion 12, ribs 121, 122 extending in the up-down direction and protruding toward the opposing side surface are formed on inner sides 12b, 12c facing each other in the front-rear direction.
The ribs 121, 122 are each formed in a plurality of pairs spaced apart in the left-right direction. More specifically, the ribs 121 formed on the inner surface 12b and the ribs 122 formed on the inner surface 12c are positioned opposite each other in the left-right direction and are formed at equal pitches in the left-right direction. All of the multiple ribs 121 have the same protruding height. All of the multiple ribs 122 have the same protruding height.

The width of the insertion portion 12 in the left-right direction is defined by the distance Lb, and the distance between the tip position of the rib 121 and the tip position of the rib 122 in the front-rear direction is defined by the distance Lc. Distances Lb and Lc will be described later.

The through hole 11 is formed as a long hole with its longitudinal direction extending in the left-right direction.
In this example, the left and right end faces of the through hole 11 are cut in the vertical center portion so that the hole expands to the left and right, forming cut portions 11a and 11b, respectively.
The cut portions 11a and 11b are formed at the left and right ends of the through hole 11 and are triangular cut portions whose width narrows toward the ends. The shape of the cut portions 11a and 11b is not limited to a triangular shape and may be a semicircular shape, an elliptical shape, or the like.

The above-mentioned rotating tool 1 can be integrated with a card holder 2 as shown in FIGS.
The card holder 2 is designed to hold the card 3 inserted through an insertion slot 2a, which is used to insert and remove cards such as an ID card for personal authentication, by friction, as shown by the arrow DR2 in Fig. 4. The card holder 2 is a so-called hard type made of hard resin such as polycarbonate, and is approximately 5 mm thick when the card 3 is inserted.
By inserting the long side edge 2b or the short side edge 2c of this card holder 2 into the insertion portion 12 of the rotating device 1 as shown by arrow DR1 in Figure 4, the insertion portion 12 holds the edge 2b or edge 2c of the card holder 2, and the rotating device 1 is attached and held in the card holder 2.
The combination of the rotating tool 1 attached to the card holder 2 and the two components integrated together will be referred to as a rotating part 1T hereinafter.

The rotating tool 1 is made of resin and is elastically deformable in the direction of increasing the distance Lc. Therefore, the distance Lc of the insertion portion 12 is set to be slightly smaller than the thickness of the card holder 2. Specifically, the distance Lc is set so that the card holder 2 can be manually inserted between the ribs 121 and 122 with a strong fit, and the frictional force between the ribs 121 and 122 and the inserted card holder 2 holds the rotating tool 1 in the card holder 2 to such an extent that it does not come off unintentionally.

When the thickness of the card holder 2 is 5 mm, the distance Lc is set to, for example, about 4.7 mm.
The distance Lb is set to be longer than the length of the side that is inserted into the insertion portion 12 of the card holder 2 .
For example, when only the short side portion of the card holder 2 is inserted into the insertion portion 12, the length is made longer than the short side, and when the long side portion can be inserted, the length is made longer than the long side.
It is preferable that the distance Lb be as long as possible because this reduces the amount of deformation of the rotating tool 1 caused by the pressure of the ribs 121 and 122 when a thicker card holder 2 is inserted into the insertion portion 12 .

The distance La is set so that when the card holder 2 is fully inserted into the insertion section 12, it blocks a portion of the insertion opening 2a of the card holder 2. As a result, the rotating device 1T with the rotating device 1 attached to the card holder 2 prevents the card 3 inserted into the card holder 2 from slipping out of the insertion opening 2a.

In the rotating concrete body 1T, the height of the ribs 121, 122, i.e., the distance Lc, is set so that the rotating concrete body 1 attached to and held in the card holder 2 will not come off from the card holder 2 when the card holder 2 is in normal use, and will be held to such an extent that it will come off when it is pulled out by intentionally applying force by hand.
That is, the ribs 121 and 122 function as a pressing portion 12P that presses the peripheral edge of the card holder 2 inserted into the insertion portion 12 in the thickness compression direction.
The card holder 2 is held by the rotating tool 1 by frictional force between the pressing portion 12P and the card holder 2, which corresponds to the pressing force of the pressing portion 12P.

6 is a diagram for explaining a method for opening the door 5 by using the turning mechanism 1T to turn the door handle 51 when the door 5 has an L-shaped door handle 51. The door 5 is described as being opened by pulling it towards the front, but may be opened by pushing it.
The door handle 51 has a shaft portion 51a extending on a rotation axis CL51 of the door handle 51, and an arm portion 51b extending from the tip of the shaft portion 51a in a radial direction generally perpendicular to the rotation axis CL51. The arm portion 51b is a portion that is gripped by hand when operating the door handle 51.

As shown in FIG. 6, the user holds the rotating device 1T in his/her hand 6 and passes the arm 51b of the door handle 51 through the through hole 11 of the rotating device 1 attached to the card holder 2.

Next, when the user presses down on the rotating part 1T held in the hand 6, the position of the through hole 11 is lowered and the arm 51b inserted through the through hole 11 is pressed down. This causes the door handle 51 to rotate in the clockwise direction in FIG. 6 about the rotation axis CL51 as indicated by the arrow DR3.

Since the door is unlocked when the door handle 51 is rotated to a certain extent, the user moves the rotating part 1T that he or she is holding toward the front side in FIG. 6 as indicated by an arrow DR4.
As a result, the arm portion 51b inserted into the through hole 11 enters and abuts the notch portion 11a of the through hole 11, and the door handle 51 moves toward the front side of Figure 6 together with the rotating part 1T, so that the door 5 to which the door handle 51 is attached rotates and opens.

When the door handle 51 is moved towards the front side of the paper in FIG. 6, the arm portion 51b enters and abuts against the notch portion 11a, so that the attitude and position of the rotating tool 1 relative to the arm portion 51b are stably determined.
This allows the user to grip the rotating tool 1 and move the arm portion 51b towards the user in a stable and easy manner.

In this way, by using the rotating part 1T, the door handle 51 can be rotated and moved horizontally forward to open the door 5 without touching the door handle 51. If the door 5 is a push-to-open door, the door 5 can be opened by rotating the door handle 51 and pushing it horizontally backward.

As described above, the rotating tool 1 is held in the card holder 2 by the frictional force between the pressing portion 12P and the card holder 2 when the card holder 2 is inserted into the insertion portion 12.
The card holder 2 may be formed in advance to a thickness that will be held in place by a moderate frictional force when inserted into the insertion portion 12, and may be sold as a set with the rotating device 1 as an item intended to be used in combination with the rotating device 1.
In this case, the card holder 2 and the turning tool 1 constitute a door handle turning tool set 1S.

The turning tool 1 constitutes a turning unit 1T when attached to and integrated with the card holder 2, regardless of whether the card holder 2 is formed as a turning tool set 1S. Since important cards such as ID cards are usually attached to the card holder 2 and are always carried on the person's body, by attaching and integrating the turning tool 1 with the card holder 2, there is almost no risk of forgetting to bring it with you when you need it.
Furthermore, by integrating the rotating tool 1 with the card holder 2, the rotating tool 1 does not need to be stored separately in a bag or the like. This makes the rotating tool 1 easy to handle and highly portable.

In addition, in the rotating tool 1T, the arm 51b of the door handle 51 comes into contact only with the inner surface of the through hole 11, which is difficult for fingers to touch. Therefore, the rotating tool 1 is highly hygienic.

Example 2
FIG. 7 is a perspective view showing a rotating tool 1A of the second embodiment.
In the rotating tool 1A, the insertion portion 12 remains as an insertion portion 12A having the same shape as the rotating tool 1, and the length of the through hole 11 in the left-right direction is shortened to form a through hole 11A. In the example shown in Fig. 7, the through hole 11A has a shape in which the right end of the through hole 11 is positioned approximately in the center in the left-right direction, and has an outer shape in which approximately the right half of the portion forming the insertion portion 12A protrudes to the right as a protrusion 13A.
The through hole 11A has cut portions 11Aa and 11Ab similar to the cut portions 11a and 11b of the through hole 11.
In other words, the rotating tool 1A has a flat shape with the left-right direction as shown in Fig. 7 as its longitudinal direction, and the insertion portion 12A is formed on the top surface 1Aa, which is one of the side surfaces along the longitudinal direction. The through hole 11A is formed in a lower portion on the other side surface side of the insertion portion 12A so as to penetrate in the thickness direction, which is the front-rear direction.
Furthermore, the rotating tool 11A is formed so that the through hole 11A is shorter in the longitudinal direction than the insertion portion 12A, and the width in the short direction (the up-down direction in Figure 7) of the portion where the through hole 11A is not formed is narrower than the width in the short direction of the portion where the through hole 11A is formed.

Figure 8 is a front view showing the state in which the card holder 2 is inserted and attached to the insertion portion 12A of the turning tool 1A. Hereinafter, the turning tool 1A is attached to the card holder 2 and integrated with it is referred to as the turning tool 1AT.

FIG. 9 is a diagram for explaining a method for opening the door 5 by rotating the door handle 51 using the rotating mechanism 1AT when the door 5 is provided with an L-shaped door handle 51. In FIG.
As shown in FIG. 9, the turning unit 1AT is grasped by the hand 6, and the arm portion 51b of the door handle 51 is passed through the through hole 11A of the turning unit 1A attached to the card holder 2.
Since the rotating part 1AT has a protrusion 13A, in the right-side portion, the width Db corresponding to the vertical direction between the upper end of the card holder 2 and the lower end of the protrusion 13A is smaller than the similar width Da of the rotating part 1T (see Figure 6).
Therefore, for people with small hands, the rotating part 1AT is often easier to grip than the rotating part 1T.

The rotating part 1AT can rotate the door handle 51 as indicated by the arrow DR3 and move it forward as indicated by the arrow DR4 without touching it, similar to the rotating part 1T. If the door 5 is a door that is opened by pushing it, the rotating part 1AT can rotate the door handle 51 as indicated by the arrow DR3 and move it backward in the opposite direction to the arrow DR4 without touching it, similar to the rotating part 1T.
That is, the turning tool 1A is attached to the card holder 2 to form an integrated turning mechanism 1AT, and the door 5 can be opened by turning the door handle 51 without touching it with one's hand.

The embodiment described above is not limited to the above configuration, and may be modified without departing from the spirit of the present invention.

Although an example has been shown in which the rotating tool 1, 1A is attached to the long side of the card holder 2, in the case of a card holder 2 in which a strap is passed through the short side and used in a vertical position, the rotating tool 1, 1A may be attached to the short side opposite the side through which the strap is passed.
Of course, the rotating device 1, 1A may be capable of being attached to either the short side portion or the long side portion of the card holder 2, regardless of whether the card holder is in a vertical or horizontal orientation.

The rotating tool 1, 1A only needs to be formed so that it can be attached to a common card holder 2 used by a specific organization, etc. If the organization has a small number of people, a small number of units can be produced using a 3D printer, and if the organization has a large number of people, a mold can be made and production can be carried out using injection molding, etc., so there is no limit to the production method.

In order to allow as many unspecified door handles as possible to be inserted, the through holes 11, 11A should have a width (vertical distance in Figs. 1 and 7) of 30 mm or more and a length (horizontal distance in Figs. 1 and 7) of 50 mm or more. In addition, by making the width of the through holes 11, 11A 10 mm or more and the length 30 mm or more, they can accommodate many common door handles.

The pressing portion 12P of the insertion portion 12 may be formed, instead of the ribs 121, 122, by pressing pieces 12e, 12f having flexibility in the thickness direction of the rotating tool 1, which is the front-rear direction, as shown in FIG.
FIG. 10 is a cross-sectional view taken along line S10-S10 in FIG.
In this case, the card holder 2 is inserted into the insertion section 12 with a strong fit so that the pressing pieces 12e and 12f are deformed in the thickness direction. The card holder 2 inserted into the insertion section 12 is held in place by the frictional force caused by the elastic repulsive force generated by the deformation, as the pressing pieces 12e and 12f are deformed forward and backward, respectively. Therefore, the range of thicknesses of the card holder 2 that can hold the rotating tool 1 is wide, making it highly versatile. It can be attached and held well not only in hard type card holders, but also in soft type card holders made of polyvinyl chloride resin or the like.

The structure with the pressing pieces 12e and 12f can be similarly applied to the rotating tool 1A. Also, in the rotating tool 1 and 1A, only one of the pressing pieces 12e and 12f may be formed.

The structure in which edge 2b or 2c of card holder 2 is held in insertion section 12 is not limited to the above-mentioned frictional force caused by pressing. It may be held by the attractive force between a magnet provided on edge 2b or edge 2c and a magnet provided on the insertion section 12 side. It may also be a so-called snap-fit concave-convex engagement structure.
