Hereinafter, embodiments of the present invention will be described with reference to the drawings showing examples. There are various types of door handles such as lever handles, push-pull handles, and doorknobs. As used herein, the term "handle device" means a device that plays the same role as a door handle and is additionally attached to an existing door handle or is attached in place of an existing door handle.

(1) First Embodiment FIG. 1A is an external perspective view schematically showing an example of a handle device 1 according to the first embodiment of the present invention together with a part of a door 20. The circle in FIG. 1B is a perspective view of the lever handle 23 in the state where the handle device 1 is not attached.

The door 20 opens and closes by rotating around a rotation shaft (not shown) located at the door end. The handle 23 is attached at a position of about several cm from the door side surface 21 located at the door end of the door 20 toward the door end side. In this example, the handle 23 is a lever handle. Further, a latch bolt 22 is provided on the side surface 21 of the door at a position substantially the same as that of the handle 23. The latch bolt 22 is elastically urged so as to protrude from the door side surface 21. The door frame (not shown) facing the door side surface 21 at the closed position of the door 20 is formed with a recess into which the protruding latch bolt 22 is inserted.

A case 24 is buried in the door 20. The latch release mechanism 25 (specific configuration is not shown) housed in the case 24 is connected to the lever handle 23. In the closed position of the door 20, the latch bolt 22 enters the recess of the door frame to fix the door 20, and the door 20 cannot be opened by simply pulling the lever handle 23. By rotating the lever handle 23, the latch bolt 22 is retracted into the case 24 via the latch release mechanism 25 to release the latch, and the door 20 can be opened. The door 20 opens to the side of the flat surface 22a of the latch bolt 22. Therefore, in the example of FIG. 1, the door 20 is opened by pulling the door 20 toward the front with the latch bolt 22 released.

The handle device 1 is used by being attached to the existing lever handle 23. It should be noted that a gap is provided between the attached handle device 1 and the surface of the door 20 to such an extent that the operation of the handle device 1 is not hindered. The handle device 1 has an actuating portion 4 that can be immovably fixed to the lever handle 23. The illustrated operating portion 4 has a shape that partially covers the outer surface of the lever handle 23, but this is only a shape schematically shown. Since the shape of the lever handle 23 itself is various, the specific shape of the operating portion 4 may be any shape as long as it can be fixedly fixed to the lever handle 23. Preferably, the actuating portion 4 is removable from the lever handle 23. The operating portion 4 does not have to be an integral part, and may have a structure in which the lever handle 23 is sandwiched by a plurality of divided parts, for example. Although not shown, the operating portion 4 may have a structure for fixing by using fasteners such as bolts.

The handle device 1 further has an operating unit 2 arranged vertically above the operating unit 4 by a predetermined distance. The operation unit 2 is provided to engage the elbow portion of the operator who is trying to open the door. By separating the operating unit 2 vertically upward by a predetermined distance from the operating unit 4, the operator can operate the operating unit 2 using the elbow portion without bending down.

The handle device 1 further has a force transmission unit 3 that connects the operating unit 4 and the operating unit 2. In the illustrated example, the force transmission unit 3 is composed of one long body, here a long flat plate member. The specific shape of the force transmission unit 3 is not particularly limited. The base end of the force transmission unit 3 is fixed to the actuating unit 4, and the tip end is fixed to the operation unit 2. The term "fixing" here includes both the case where the two parts are integrally molded and the case where the two members are connected by using fasteners or the like. The connection position between the force transmission unit 3 and the actuating unit 4 is, in this example, the base end of the lever portion of the lever handle 23.

2 (a) is a perspective view of the handle device 1 shown in FIG. 1 (a), (b) is a side view, and (c) is a schematic plan view. The operation unit 2 is configured so that the elbow portion of the operator can easily engage with the operation unit 2. The shape of the operation unit 2 shown in the figure is an example. The "elbow" here may be not only the "elbow" in the narrow sense, but also the elbow and its surroundings, that is, the upper region of the forearm or the lower region of the upper arm. Individual operators can use parts that are easy for them to use during operation. In order to release the latch bolt 22, the operator rotates the operation unit 2 to rotate the lever handle 23. Therefore, the operation unit 2 has at least a "rotation operation unit" with which the elbow portion of the operator engages when rotating the operation unit 2. The rotation center of the operation unit 2 coincides with the rotation center of the lever handle 23.

Further, when the operator pulls the door to open it, it is necessary to pull the door while keeping the lever handle 23 in the rotated state, that is, the latch bolt 22 in the released state. Therefore, the operation unit 2 includes at least a "pull operation unit" with which the elbow portion of the operator engages when the operation unit 2 is pulled in a direction perpendicular to the surface of the door 20. The rotation operation unit and the pull operation unit in the operation unit 2 do not need to be clearly distinguished, and there may be a portion that can be used for both rotation and pulling.

In the illustrated example, the operation unit 2 has a saddle-shaped portion connected to the upper end of a long flat plate member of the force transmission unit 3. The ridge line 2a of this saddle-shaped portion shown by a broken line draws a convex curve in a plane parallel to the plane of the door 20 in the mounted state. The convex curve is a circumference in the illustrated example, but may be an arc, an ellipse, an elliptical arc, or any convex curve as another example. A concave surface 2b having the ridge line 2a as a valley is formed. The concave surface 2b forms a rotation operation portion in the operation portion 2. The diameter of the concave surface 2b gradually increases in both directions perpendicular to the door 20 from the ridge line 2a, and the peripheral portions form wall portions 2d, respectively. Therefore, the operation unit 2 is shaped like two trumpet outlets back to back. One wall portion 2d forms a pulling operation portion in the operation portion 2.

In the illustrated example, the operation unit 2 has a symmetrical shape with respect to the surface including the ridge line 2a. As another example, the operation unit 2 may have an asymmetrical shape in which the diameter of the wall portion 2d on the side closer to the door 20 is smaller than the diameter of the wall portion 2d on the side far from the door 20.

The distance L between the pair of wall portions 2d, which is schematically shown in FIG. 2 (b), is long enough to allow the elbow portion of the assumed average operator to enter with a margin. For example, it is about 10 cm. The depth of the saddle-shaped portion is such that the elbow portion is appropriately engaged, for example, about 4 to 5 cm. However, the length is not limited to these. The recess of the operation portion 2 thus formed has a shape in which the elbow portion of the operator can easily enter, preferably at least a shape in which the elbow head can be easily pressed, and a shape in which the elbow portion can be easily separated from the operation portion 2 after the operation. But it is also. The ridge line 2a and the concave surface 2b do not have to exist over the entire circumference of the axis in the direction perpendicular to the surface of the door 20, and the angle range in which the elbow portion may hit when the operation portion 2 is rotated. It suffices to form (see the angle β in FIG. 2A).

The vertical distance H between the operating unit 4 and the operating unit 2 schematically shown in FIG. 2B is preferably 20 to 40 cm (the same applies to the following embodiments). The distance H here is the length from the height position of the handle to the midpoint position of the vertical length of the operation unit 2 (the same applies to the following embodiments). Since the height position of the normal handle is about 85 to 100 cm from the floor surface, the operation position is raised by the distance H. As a result, the operator can operate the operation unit 2 with the elbow portion while standing straight. However, since the height of the operator varies, it is not necessary to set the distance H strictly.

In the illustrated example, the upper end of the force transmission unit 3 is connected to a position closer to the door 20 at the bottom of the operation unit 2. However, the shape of the force transmitting portion 3 and the connecting position thereof can be appropriately designed according to the shape of the handle and the structure of the operating portion 4.

FIG. 3 shows an example of the operating state of the handle device 1 shown in FIGS. 1 and 2. Preferably, the operator's elbow portion 30 is placed in the rotation operation portion of the operation portion 2, that is, the recessed portion, and is rotated as shown by the arrow I. Alternatively, the operator's elbow portion 30 (particularly the elbow head) is in contact with any part of the operation portion 2 (for example, the outer peripheral edge of the wall portion 2d) without inserting the elbow portion 30 of the operator 30 into the recessed portion. If so, the rotation operation is possible by friction (the same applies to other embodiments). When the elbow portion 30 is inserted into the recessed portion, the elbow portion 30 engages with the concave surface 2b of the operation portion 2 shown in FIG.

The force applied to the operation unit 2 is transmitted to the lever handle 23 via the force transmission unit 3 and the actuating unit 4, and the lever handle 23 rotates as shown by arrow II. As a result, the latch bolt 22 is retracted and released. At that point, the door 20 is still closed. After that, when the operation unit 2 is pulled in the direction perpendicular to the surface of the door 20 as shown by the arrow III while the handle device 1 is maintained in the rotational position, the door 20 opens as shown by the arrow IV. At this time, the elbow portion preferably engages with the pull operation portion in the operation portion 2, that is, the wall portion 2d on the front side. Even if the elbow portion 30 is not completely inserted in the recessed portion, the operation portion 2 can be pulled horizontally by friction (the same applies to other embodiments).

After the door 20 is sufficiently opened, the operator separates the elbow portion 30 from the operation portion 2 and moves to the space on the opposite side of the door 20. The concave surface 2b of the operation portion 2 has a shape in which the elbow portion 30 is naturally easily separated. Therefore, the operator can perform contact, operation, and withdrawal from the operation unit 2 as a series of flows.

After that, if the door 20 closes automatically, the operator does not need to do anything. If the door 20 does not close automatically, the handle device similarly attached to the back side of the door 20 may be operated by the elbow. For example, after passing through the door 20, the elbow portion 30 may be engaged with the operating portion of the handle device on the back side by looking back and pulled in the direction in which the door 20 is closed. When the door 20 is closed, the latch bolt 22 is automatically retracted, so that it is not necessary to rotate the lever handle.

When opening the door 20 from the back side of the illustrated surface, push the door 20 to open it. In that case, the handle device on the back side of the door 20 is similarly rotated using the elbow portion to retract the latch bolt 22 to release it, and then the operation portion 2 is pushed horizontally to open the door 20. be able to.

(2) Second Embodiment FIG. 4 is an external perspective view schematically showing an example of the handle device 1A according to the second embodiment of the present invention together with a part of the door 20.

The handle device 1A is attached to the lever handle 23 as in the first embodiment. The operating unit 4 and the operating unit 2 have the same shape as that of the first embodiment, but the force transmitting unit 3 extends vertically upward from the base portion to the middle, and bends and extends toward the door tail side in the middle. There is. Therefore, the operation unit 2 is arranged in a plane parallel to the surface of the door 20 by a predetermined distance in a direction forming a predetermined angle α on the door tail side of the door 20 with respect to the vertical upper side of the operating unit 4. Has been done. The angle α is preferably 45 ° or less. This embodiment is particularly effective when a wall or the like is present next to the door frame facing the door side surface 21. This is because the distance from such a wall or the like to the operation unit 2 becomes longer, so that it becomes difficult for the fingers or the like to hit the wall or the like when operating the operation unit 2 with the elbow portion. The features of this second embodiment are also applicable to the following other embodiments.

Also in the second embodiment, the distance H in the vertical direction between the operating unit 4 and the operating unit 2 is preferably 20 to 40 cm.

(3) Third Embodiment FIG. 5 (a) is a schematic partial perspective view of an example of the handle device 1B according to the third embodiment of the present invention, and (b) and (c) are modifications of (a). It is a schematic partial perspective view of a form. This embodiment is a modification of the operation unit 2 and the force transmission unit 3 in each of the above-described embodiments. The force transmission unit 3 is one long flat plate member in this example. The operation unit 2 is connected to the upper end of the force transmission unit 3. The moving part is not shown.

In this example, the rotation operation portion in the operation portion 2 is a convex surface 2c which is a part of a cylindrical surface, and the pull operation portion is a pair of plate-shaped wall portions 2d supported by both ends of the convex surface 2c. As a result, a recessed portion is formed. This embodiment has a relatively simple shape. The convex surface 2c does not have to exist over the entire circumference of the shaft, and it is sufficient that the convex surface 2c is formed in an angle range in which the elbow portion may hit when the operation portion 2 is rotated. In the illustrated example, the convex surface 2c is formed only by the upper half of the cylindrical body. When the operation unit 2 is pulled in a direction perpendicular to the surface of the door 20, the elbow portion of the operator engages with the wall portion 2d farther from the door 20. It suffices if the wall portion 2d is also provided in a range where the elbow portion engages.

In the handle devices 1Ba and 1Bb in the modified form shown in FIGS. 5 (b) and 5 (c), the convex surface 2c of the substantially cylindrical surface of the operation unit 2 is formed in a range of about 90 ° around the axis, and a pair on both sides thereof. The wall portion 2d is inclined outward so that the distance between them increases upward. Further, on the outer peripheral edge of each wall portion 2d, a return portion 2d1 having a rounded shape and projecting outward is provided. The presence of the return portion 2d1 facilitates the operator's elbow portion to engage with the operation portion 2. The width of the force transmission unit 3 is different between FIGS. 5 (b) and 5 (c).

(4) Fourth Embodiment FIG. 6A is a partial perspective view schematically showing an example of the handle device 1C according to the fourth embodiment of the present invention, and FIG. 6B is a partial perspective view showing x of (a). -X cross-sectional view. (C) is a modified form. The moving part is not shown.

The operation unit 2 in each of the above-described embodiments has a concave surface 2b or a convex surface 2c which is a rotation operation unit, and a pair of wall portions 2d which are pull operation units. As described in each embodiment, when the operation unit 2 is pulled toward the front, the elbow portion can be engaged with the wall portion 2d on the front side and pulled. Further, when pushing the operation portion 2, the elbow portion can be engaged with any wall portion 2d and pushed (that is, the pull operation portion can also be used for pushing).

From this, in order to pull or push the operation unit 2, it is sufficient to have at least the wall portion 2d on the front side (the side far from the door). In the fourth embodiment, the operation unit 2 has only the front wall portion 2d. That is, it can be said that the operation unit 2 shown in FIG. 6A has only one of the two back-to-back trumpet outlets 2 shown in FIG. 2 divided vertically in half. It is formed by a concave surface 2b formed by gradually increasing the diameter from the peripheral edge of a circular end surface having a small diameter located in a plane parallel to the surface of the door 20 toward the direction perpendicular to the door 20, and the peripheral edge portion of the concave surface 2b. It has one wall portion 2d.

Preferably, a return portion 2d1 having a rounded shape and projecting inward is provided on the outer peripheral edge of the wall portion 2d. The presence of the return portion 2d1 facilitates engagement of the operator's elbow portion.

Note that, as shown in the handle device 1Ca in the modified form of FIG. 6C, a cylindrical surface 2c can be used instead of the concave surface 2b. In that case, it has a cylindrical surface 2c having an axis perpendicular to the door 20 and one wall portion 2d supported by the end of the cylindrical surface 2c farther from the door 20. In the illustrated example, the cylindrical surface 2c is provided over the entire circumference of the shaft, but may be provided in a predetermined angle range instead.

(5) Fifth Embodiment FIG. 7A is an external perspective view schematically showing an example of the handle device 1D according to the fifth embodiment of the present invention together with a part of the door 20. (B) is a perspective view of the push-pull handle of (a) in a state where the handle device is not attached. (C) shows another handle device 1D attached to the back side of the door 20.

In the fifth embodiment, the handle device 1D is attached to the handle 23 which is a push-pull handle. In FIG. 7B, the push-pull handle 23 has a square plate shape as an example, but there are various other forms such as a vertically long rod shape. When the push-pull handle is pushed or pulled, the latch bolt 22 is retracted and released, and when the push handle is further pushed or pulled, the door 20 can be opened.

In the handle device 1D, the operation unit 2 and the force transmission unit 3 have the same shape as that of the first embodiment, but the operating unit 4 is configured to fit the shape of the push-pull handle 23. The specific configuration of the operating unit 4 can be implemented in various ways.

As shown in FIG. 7A, when the elbow portion (not shown) is engaged with the wall portion 2d in front of the operation portion 2 and pulled as shown by the arrow I, the force transmission portion 3 and the actuating portion 4 are used. The force is transmitted and the push-pull handle 23 is also pulled as shown by arrow II. As a result, the latch bolt 22 retracts, and the door 20 can be opened by pulling the wall portion 2d of the operation portion 2 in the horizontal direction as it is.

As shown in FIG. 7 (c), on the back side of the door 20, when the elbow portion (not shown) is engaged with the operation portion 2 and pushed as shown by the arrow III, the force transmission portion 3 and the actuating portion 4 are pressed. The force is transmitted through the push-pull handle 23, and the push-pull handle 23 is also pushed as shown by the arrow IV. At this time, the elbow portion may be inserted into the operation portion 2 and the wall portion 2d on the side close to the door 20 may be pushed, but instead, the outer surface of the wall portion 2d on the front side may be pushed. As a result, the latch bolt 22 is retracted and released, and the door 20 can be opened by pushing the operation unit 2 toward the door 20 in the horizontal direction as it is.

The

handle devices

1, 1A to 1D of each embodiment described with reference to FIGS. 1 to 7 above can be attached to the handles of existing doors. Further, the scope of the present invention also includes a form in which a part of the configuration of each embodiment is combined with each other.

(6) Sixth Embodiment FIG. 8 is an external perspective view schematically showing an example of the handle device 1E according to the sixth embodiment of the present invention together with a part of the door 20. In the sixth embodiment, there is no existing door handle, and the actuating portion 4 of the handle device 1E is attached to the position of the existing handle.

The latch bolt 22 protrudes from the substantially rectangular parallelepiped case 24 embedded inside the door 20. A spring (not shown) that elastically urges the latch bolt 22 is provided in the case 24. In FIG. 8, since the flat surface 22a at the tip of the latch bolt 22 is on the front side, the door 20 is a door that is pulled toward the front side to open.

Further, a latch release mechanism 25 for retracting the latch bolt 22 against the spring is provided in the case 24. The latch release mechanism 25 is directly connected to the operating portion 4 of the handle device 1E. When the operator operates the handle device 1E as shown by an arrow, the latch release mechanism 25 in the case 24 is activated, and the latch bolt 22 is retracted into the case 24 and released. The door 20 can be opened when the latch bolt 22 is released.

The handle device 1E is attached so as to protrude from the door surface at a position of about several cm on the door end side in the horizontal direction from the door side surface 21. The handle device 1E has an operating portion 4, and a mounting structure for the door surface is provided at the base end of the operating portion 4. In the illustrated example, the mounting structure of the operating portion 4 to the door 20 is the same as the mounting structure of a general lever handle. The actuating portion 4 is directly connected to the latch release mechanism 25 in the case 24 provided inside the door 20, and the latch release mechanism 25 can be directly operated. Therefore, the operating portion 4 is located at substantially the same height as the latch bolt 22.

The actuating portion 4 is rotatably attached to the door 20 around a rotation shaft C extending in a direction perpendicular to the surface of the door 20. In the example of FIG. 1, the operating portion 4 is a cylindrical body, and its axis coincides with the rotating shaft C. The specific shape of the operating portion 4 is not limited to this. The protruding length from the door surface to the tip of the operating portion 4 is set so that the operator can easily operate the handle device 1E.

The handle device 1E further has an operating unit 2 arranged vertically above the operating unit 4 by a predetermined distance. The operation unit 2 includes a portion with which the elbow portion of the operator who is trying to open the door is engaged. By separating the operating unit 2 vertically upward by a predetermined distance from the operating unit 4, the operator can operate the operating unit 2 using the elbow portion without bending down.

The handle device 1E further has a force transmission unit 3 arranged between the actuating unit 4 and the operation unit 2 and connecting them. In the illustrated example, the force transmission unit 3 is composed of one long body, here a long plate member. The specific shape of the force transmission unit 3 is not particularly limited.

Since the operation unit 2 and the force transmission unit 3 are the same as those in each of the above-described embodiments, detailed explanations will be omitted.

(7) Seventh embodiment
FIG. 9 is an external perspective view schematically showing an example of the handle device 1F according to the seventh embodiment of the present invention together with a part of the door 20.

The handle device 1F is attached to the door surface of the door 20 by the operating unit 4 as in the sixth embodiment, and has an operation unit 2 and a force transmission unit 3. The actuating portion 4 is directly connected to the latch release mechanism 25. The difference from the sixth embodiment is that the operating unit 2 is not located vertically above the operating unit 4. In the seventh embodiment, the operation unit 2 has a predetermined distance in a plane parallel to the surface of the door 20 in a direction forming a predetermined angle α on the door tail side of the door 20 with respect to the vertical upper side of the operating unit 4. They are placed apart. The angle α is preferably 45 ° or less. In the illustrated example, the force transmission unit 3 is a flat plate member inclined with respect to the vertical direction.

In this embodiment, as shown by the arrow, when the operator operates the operation unit 2 with the elbow portion, there is an advantage that the fingers or the like are less likely to hit the wall or the like located on the door end side.

The

handle devices

1E and 1F described with reference to FIGS. 8 and 9 above can be attached to the door in place of the existing handles of the door. The shapes of the operation units 2 and the force transmission units 3 of the

handle devices

1, 1A to 1D described with reference to FIGS. 1 to 7 are also the same as those of the

handle devices

1E and 1F shown in FIGS. 8 and 9. Can be applied.

(8) Eighth Embodiment FIG. 10 is an external perspective view schematically showing an example of the handle device 1G according to the eighth embodiment of the present invention together with a part of a door. FIG. 11 is a schematic side view of the door handle device shown in FIG.

The door 20 opens toward the door surface side shown by rotating around a rotation axis (not shown) on the door tail side. A general latch bolt 22 is provided on the side surface of the door located on the door end side opposite to the rotating shaft. The latch bolt 22 is housed in a case 24 embedded inside the door 20. A spring (not shown) that elastically urges the latch bolt 22 to project is provided in the case 24. Further, a latch release mechanism 25 for retracting the latch bolt 22 against the spring is provided in the case 24. The latch release mechanism 25 is connected to the handle 23. In FIG. 10, the door 20 is fixed in the closed position by the latch bolt 22 protruding. Normally, the latch bolt 22 is retracted and released by turning the handle 23 against the spring force, and the door 20 can be opened by pulling the handle 23 as it is. In the illustrated example, the handle 23 is a doorknob. As another example, the handle 23 may be a lever handle.

A handle device 1G is preferably attached to the door 20 and the door knob 23 shown in FIG. 10 in a detachable manner. The handle device 1G has a function for rotating the door knob 23 with the elbow of the operator and a function for pulling the door 20 to open the door knob 23 without directly operating the door knob 23 with the operator's fingers. ..

The handle device 1G has an actuating portion 4 that can be immovably fixed to the door knob 23. In the illustrated example, the actuating portion 4 has a ring shape that concentrically surrounds the doorknob 23, is removable from the doorknob 23, and is fixed, for example, by an appropriate fastener (not shown). The specific shape of the actuating portion 4 may be any shape as long as it can be fixedly fixed to the doorknob 23.

The handle device 1G further has a rotation operation unit 2c. The rotation operation unit 2c is arranged diagonally upward from the operating unit 4 by a predetermined distance. The "obliquely upward" is a direction inclined by a predetermined angle toward the door tail side with respect to the vertical upper side of the operating portion 4, for example, a direction forming an angle of 45 degrees or less with the vertical upper side. The rotation operation unit 2c has a portion extending at a predetermined length in a direction perpendicular to the surface of the door 20. In the illustrated example, the rotation operation unit 4 is a columnar rod, but the shape is not limited to this. In this example, the operator presses the elbow portion from the door tail side against the rotation operation unit 2c and rotates the elbow portion toward the door tip side as indicated by an arrow. Since the rotation operation unit 2c is located higher than the doorknob 23 in the vertical direction, the operator can operate the rotation operation unit 2c using the elbow portion without bending down. The "elbow" is a range including the vicinity of the elbow.

The handle device 1G further has a force transmission unit 3 that connects the actuating unit 4 and the rotation operation unit 2c. The force transmission unit 3 is a long plate member extending linearly in the illustrated example, but the shape is not limited to this. The base end of the force transmission unit 3 is fixed to the actuating unit 4, and the upper end is fixed to the intermediate position of the rotation operation unit 2c. The connection between the actuating unit 4 and the force transmission unit 3 and the connection between the force transmission unit 3 and the rotation operation unit 2c may be performed by integrally molding the material, or by using appropriate fasteners. You may go there.

Although not shown, as another example, instead of attaching the actuating portion 4 to the handle 23, the existing handle 23 is removed from the case 24, and the actuating portion 4 having an appropriate shape is directly connected to the latch release mechanism 25 in the case 24. It is also possible (see the actuating portion 4 shown in FIG. 16 described later).

Although not shown, as another example, the rotation operation unit 2c may be arranged vertically above the handle 23, not diagonally above, at a distance of a predetermined distance.

Further, a pull operation unit 2d is provided at an end portion of the rotation operation unit 2c farther from the door 20. The pull operation unit 2d is supported by the rotation operation unit 2c. The pulling operation unit 2d has a wide surface facing at least the surface of the door 20. In the illustrated example, the pull operation portion 2d has a disk shape, and the end portion of the rotation operation portion 2c is connected to the center thereof. In the illustrated example, in order to reduce the weight of the pulling operation portion 2d, a plurality of circular notches are formed penetrating the pulling operation portion 2d. The pull operation unit 2d is a portion where the elbow portion is pressed against the door 20 when the operator pulls the door 20 to open it. Therefore, the distance between the pull operation portion 2d and the door 20 is set so that the elbow portion of the operator can be sufficiently inserted. The shape of the pull operation unit 2d and the connection point with the rotation operation unit 2c are not limited to the illustrated example.

Further, a locking portion 6 is provided at the end of the rotation operation portion 2c closer to the door 20. In the illustrated example, the locking portion 6 is a rectangular flat plate having a wide surface parallel to the surface of the door 20 and a predetermined thickness. The end portion of the rotation operation portion 2c is connected to the central portion of the surface of the locking portion 6 opposite to the door. The surface of the locking portion 6 facing the door side and the surface of the door 20 are substantially in contact with each other or have a slight gap.

Further, the holding portion 7 linked with the locking portion 6 is fixed at a predetermined position on the surface of the door 20. When the rotation operation portion 2c is rotated by the elbow portion of the operator, the locking portion 6 rotates together with the rotation operation portion 2c as shown by an arrow and moves so as to substantially slide on the surface of the door 20. .. At the position where the rotation operation portion 2c is rotated by a predetermined angle, the locking portion 6 is received in the cavity formed in the holding portion 7. By receiving the locking portion 6, the holding portion 7 serves to prevent the locking portion 6 from moving in the direction perpendicular to the surface of the door 20.

In this example, since the handle 23 is a doorknob, it is preferable to rotate the rotation operation unit 2c toward the door end side. This is because the doorknob can usually be unlatched by turning it in either the door end side (clockwise here) or the door end side (counterclockwise here). In this example, by attaching the holding portion 7 to the door end side of the locking portion 6, the holding portion 7 is a stopper of the rotation operating portion 2c when the rotation operating portion 2c is rotated to the door end side. It can also play a role. As a result, it is possible to prevent the locking portion 6 (and thus the pulling operation portion 2d) from protruding from the door end side when the rotation operation portion 2c is rotated.

Although not shown, as another example, it is also possible to attach the holding portion 7 to the door tail side of the locking portion 6 and rotate the rotation operation unit 2c toward the door tail side. Although not shown, as yet another example, since the doorknob 23 can rotate in any direction, it is possible to mount the holding portion 7 at two locations, the door end side and the door tail side of the locking portion 6. Is.

When the operator rotates the rotation operation unit 2c using the elbow portion, the door knob 23 rotates via the force transmission unit 3 and the actuating unit 4, and the latch bolt 22 retracts and is released. At this time, the elbow portion of the operator is in a position where a force can be immediately applied to the pulling operation portion 2d. Therefore, the operator can continue to open the door 20 by pulling the pulling operation portion 2d using the elbow portion. At this time, the force applied to the pull operation unit 2d is mainly transmitted from the rotation operation unit 2c to the holding unit 7 via the locking unit 6, and is transmitted from the holding unit 7 to the door 20 to pull the door 20. Since the direction of transmission of this force is perpendicular to the surface of the door 20, the force can be stably transmitted without loss. In this way, the locking portion 6 and the holding portion 7 play a role of assisting the door opening operation.

If the locking portion 6 and the holding portion 7 do not exist, the force applied to the pulling operation portion 2d is transmitted to the door knob 23 via the force transmitting portion 3 extending parallel to the surface of the door 20, and the door knob 23 Will be transmitted to the door 20. In that case, since a shearing force acts on the force transmission unit 3, the force transmission unit 3 may be distorted. This is particularly remarkable in the heavy door 20, and the force transmitting portion 3 and the connecting portion thereof require sufficient strength. In the present invention, by providing the locking portion 6 and the holding portion 7, the load on the force transmitting portion 3 can be greatly reduced. As a result, the handle device 1G can be made lighter and smaller.

FIG. 12A is an enlarged front view schematically showing the locking portion 6 and the holding portion 7 shown in FIG. 10 at the rotation position of the locking portion 6. In FIG. 12A, the position of the locking portion 6 shown in FIG. 10 is indicated by a chain line. 12 (b) is a schematic cross-sectional view of (a) in the A direction.

The holding portion 7 has a substantially U-shaped outer shell when viewed from the front. The pair of

leg portions

71a and 71b in the U-shape are curved and extend along a circle which is a rotation locus of the locking portion 6, respectively. A notch 72 is formed between the

legs

71a and 71b. The notch 72 is open on the side facing the locking portion 6. One ends of the

legs

71a and 71b are connected to each other by a base portion 73. A cavity 74 capable of receiving the locking portion 6 is formed between the

legs

71a and 71b and the surface of the door 20. The cavity 74 is open on the side facing the locking portion 6 and at the notch 72.

When the rotation operation unit 2c is pushed by the operator's elbow portion and rotates, the locking portion 6 also rotates to reach the holding portion 7, enters the cavity 74, and further rotates. The cavity 74 has a gap such that the locking portion 6 can move smoothly. The rotation operation unit 2c projects from the notch portion 72 and rotates along the notch portion 72. Finally, the rotation operation portion 2c and the locking portion 6 hit the base portion 73 and stop. When the locking portion 6 is received by the cavity 74, it is prevented from moving in the direction perpendicular to the surface of the door 20 by the

legs

71a and 71b. As long as the locking portion 6 has a holding function, the specific shape of the holding portion 7 is not limited to the illustrated example.

The holding portion 7 is firmly fixed on the surface of the door 20 by the

screws

76a and 76b passed through the holes of the fixing

protrusions

75a and 75b provided on both sides of the outer shell and the

screws

76c and 76d passed through the base 73. .. The method of attaching the holding portion 7 to the door 20 is not limited to the illustrated example.

(9) Ninth Embodiment FIG. 13 is an external perspective view schematically showing a handle device 1H according to a ninth embodiment of the present invention together with a part of a door. FIG. 14 is a schematic front view of the door handle device shown in FIG.

In this example, by turning the handle 23, which is the shape of the lever handle, the latch bolt 22 is retracted and released, and the door 20 can be pulled to open it. In the case of the lever handle, the rotation direction of the handle 23 shown in the figure is counterclockwise as shown by an arrow. However, the lever handle is an example of the handle 23, and the handle 23 may be the doorknob shown in the eighth embodiment.

In the handle device 1H of the ninth embodiment, the operating portion 4 is immovably fixed to the lever base of the lever handle 20. Preferably, the actuating portion 4 is detachably attached. In the illustrated example, the rotation operation unit 2f is arranged diagonally above the operating unit 4, that is, in a direction forming a predetermined angle from vertically above to the door tail side, at a distance of a predetermined distance. Further, in the illustrated example, the portion of the force transmitting portion 3 close to the operating portion 4 extends in the vertical direction, bends toward the door end at the intermediate point, is inclined, and extends to the rotation operation portion 2f. .. As a result, the distance between the rotation operation portion 2f and the door end of the door 20 becomes large, so that when the rotation operation portion 2f is operated by the elbow portion, the fingers are less likely to hit the wall or the like. However, as another example, the rotation operation unit 2f may be arranged vertically above the operating unit 4, and the force transmission unit 3 may extend vertically above.

The rotation operation unit 2f includes a portion extending with a predetermined length in a direction perpendicular to the surface of the door 20. In the illustrated example, the rotation operation unit 2f has a rectangular flat plate shape, but is not limited to this shape. When the operator intends to rotate the lever handle 20, the operator presses the elbow portion against the rotation operation portion 2f.

In the ninth embodiment, the pull operation unit 2d is not connected to the rotation operation unit 2f and is separated. The front view of FIG. 14 shows an example of the relative positional relationship between the rotation operation unit 2f and the pull operation unit 2d. In this example, the pulling operation unit 2d is completely separated from the rotation operation unit 2f at the position before rotation.

As shown in FIG. 13, the pull operation portion 2d is fixed to the door 20 via the connecting portion 8. The connecting portion 8 includes a portion extending in a direction perpendicular to the surface of the door 20. In the illustrated example, the connecting portion 8 is a columnar rod body. One end of the connecting portion 8 is firmly fixed on the surface of the door 20 by an appropriate fixture 9. The other end of the connecting portion 8 supports the pulling operation portion 2d. The shape of the pulling operation unit 2d is the same as that of the eighth embodiment, and has a wide surface facing at least the surface of the door 20. The pull operation unit 2d is a portion that presses the elbow portion of the operator when the operator pulls the door 20 to open it. Therefore, the distance between the pulling operation portion 2d and the door 20 is set so that the elbow portion of the operator can be sufficiently inserted. In the illustrated example, the connecting portion 8 is connected to the center of the pulling operation portion 2d, but the shape of the pulling operation portion 2d and the connecting position with the connecting portion 8 are not limited to this.

FIG. 15 is a front view showing a state when the operator rotates the rotation operation unit 2f counterclockwise as shown by an arrow. As a result, the lever handle 20 rotates via the force transmission unit 3 and the actuating unit 4, and the latch bolt 22 retracts and is released. In this rotation position, the rotation operation unit 2f is located between the pull operation unit 2d and the surface of the door 20. That is, in the rotation position, the elbow portion of the operator reaches the position of the pull operation portion 2d that hits the wide surface facing the door 20. The relative positions of the rotation operation unit 2f and the pull operation unit 2d are appropriately designed to realize this state. In the illustrated example, the rotation operation unit 2f and the connection unit 8 are not in contact with each other at the rotation position, but as another example, at the rotation position, the rotation operation unit 2f hits the connection unit 8 and stops. You may.

The operator can continue to open the door 20 by pulling the operation unit 2d with the elbow part. At this time, the force applied to the pulling operation portion 2d is transmitted to the door 20 via the connecting portion 8 and the fixture 9. Since the transmission direction of this force is the direction perpendicular to the door 20, a sufficient force can be stably transmitted. This effect is the same as that of the eighth embodiment.

Although not shown, as another example, when the handle 23 in the ninth embodiment is a doorknob, the pull operation portion 2d, the connecting portion 8 and the fixture 9 are attached to the door 20 on the door end side of the rotation operation portion 2f. It may be mounted on the surface and the rotation operation unit 2f may be rotated clockwise.

Although not shown, as yet another example, in the ninth embodiment, instead of attaching the actuating portion 4 to the handle 23, the handle 23 is removed, and the actuating portion 4 having an appropriate shape is attached to the latch release mechanism 25 inside the door 20. It may be directly connected to (see the actuating portion 4 shown in FIG. 16 described later).

(10) Tenth Embodiment FIG. 16 is an external perspective view schematically showing an example of the handle device 1J according to the tenth embodiment of the present invention together with a part of a door. FIG. 17 is a schematic front view of the door handle device shown in FIG.

The handle device 1J has an actuating portion 4 having an appropriate shape. The actuating portion 4 is directly connected to the latch release mechanism 25 in the case 24 embedded inside the door 20. In this example, the shaft of the actuating portion 4, which is a cylindrical body, is located on the extension of the rotation shaft in the latch release mechanism. Here, the actuating portion 4 itself plays the same role as a normal handle. In the present embodiment, the handle originally provided on the door 20 is removed, or the door 20 is a new door to which the handle is not attached. Although not shown, as another example, the actuating portion 4 can be immovably fixed to an existing doorknob or lever handle as shown in FIGS. 10 and 13.

In the illustrated example, the rotation operation unit 2f is arranged diagonally above the operating unit 4, that is, in a direction forming a predetermined angle from vertically above to the door tail side, at a distance of a predetermined distance. Further, in the illustrated example, the portion of the force transmitting portion 3 close to the operating portion 4 extends in the vertical direction, bends toward the door end at the intermediate point, is inclined, and extends to the rotation operation portion 2f. .. As a result, the distance between the rotation operation portion 2f and the door end of the door 20 becomes large, so that when the rotation operation portion 2f is operated by the elbow portion, the fingers are less likely to hit the wall or the like. However, as another example, the rotation operation unit 2f may be arranged vertically above the operating unit 4, and the force transmission unit 3 may extend vertically above.

The rotation operation unit 2f includes a portion extending with a predetermined length in a direction perpendicular to the surface of the door 20. In the illustrated example, the rotation operation unit 2f has a shape obtained by dividing a cylindrical member in half along an axis. The concave portion of this semi-cylindrical body faces in the direction of rotation of the rotation operation unit 2f. That is, the rotation operation unit 2f has a shape provided with a recess that opens toward the front in the rotation direction.

Also in the tenth embodiment, as in the ninth embodiment, the pull operation unit 2d is not connected to the rotation operation unit 2f and is separated. The configuration of the pulling operation portion 2d, the connecting portion 8, and the fixture 9 is the same as that of the ninth embodiment. The connecting portion 8 is a columnar rod body.

FIG. 18 is a front view showing a state when the operator rotates the rotation operation unit 2f counterclockwise. In FIG. 18, a part of the pulling operation unit 2d is cut out for the sake of clarity.

By the rotation of the rotation operation unit 2f, the latch release mechanism 25 is operated via the force transmission unit 3 and the actuating unit 4, and the latch bolt 22 is retracted and released. At this rotation position, the cylindrical rod body of the connecting portion 8 enters the recess of the semi-cylindrical body of the rotation operation portion 2f and engages with each other. As described above, the connecting portion 8 has a shape capable of entering the recess of the rotating operating portion 2f when the rotating operating portion rotates. As a result, the rotation operation unit 2f hits the connecting unit 8 and stops.

The operator can continue to open the door 20 by pulling the operation unit 2d with the elbow part. At this time, the force applied to the pulling operation portion 2d is transmitted to the door 20 via the connecting portion 8 and the fixture 9. Since the transmission direction of this force is the direction perpendicular to the door 20, a sufficient force can be stably transmitted. This effect is the same as that of the ninth embodiment.

Although the present invention has been described above with reference to the drawings showing some embodiments of the present invention, the present invention also includes embodiments in which the characteristic configurations of the respective embodiments are combined. Further, as long as it is in line with the gist of the present invention, a wider variety of modified forms are possible.
