Description

  The present invention relates to a door holding member and an apparatus for holding an openable / closable door in an open position.

  2. Description of the Related Art Conventionally, various types of door holding devices for holding an open door have been devised for doors attached to the inside and outside of a building.

  For example, it has been known for a long time to provide a rotatable ring for a door placed on a floor and hold the open door by hooking this ring on a hook provided on the door.

  In recent years, as shown in Patent Document 1, a door stop having a concave portion is fixed to a floor surface, and a pin that is provided on the door side and that can be expanded and contracted in the vertical direction is fitted into the concave portion to hold an open door. There are also things.

  Moreover, for example, as shown in Patent Document 2, a locking groove is provided on the upper surface of a door stop main body that can be expanded and contracted in the vertical direction using a spring, and a locking body provided on the door side is fitted into the groove. Some of them hold open doors.

  The type that hooks the door ring on the door hook needs to bend when the ring is hooked on or off the hook, especially for elderly people Absent.

  Next, the type described in Patent Document 1 in which a pin that is extendable in the vertical direction provided on the door side is fitted into a concave portion per door installed on the floor surface is provided with a pin case provided on the door side. The pin is lifted by an operation such as stepping on, and when releasing the state of holding the door, it is necessary to perform an operation such as stepping on the pin case with the foot to release the pin from the recess Therefore, it is difficult to say that the release operability is good (see Patent Document 1, paragraph 0013).

And the type which provided the latching groove in the upper surface of the door stop main body which can be extended-contracted to the up-down direction using the spring described in patent document 2, and the latching body provided in the door side fits into a groove | channel and latches In the case of releasing the state in which the door is held, the fitting state between the door-stop main body and the locking body can be released by an operation of pulling the door forward (see Patent Document 2, Paragraph 0019). ) Although it can be said that the operability has been improved, it is necessary to perform a heavy lifting release operation by grasping and pulling a predetermined part such as a door handle, etc. Then, there is room for improvement in operability.

  Then, an object of this invention is to provide the door holding | maintenance apparatus with the operativity at the time of canceling | releasing holding | maintenance of the opened door.

  The present invention is a holding member (20) having a wall surface portion (22a1) which faces the closing direction side of the door pin member (10) moving in the closing direction and disables the movement, and is opened from the state. In conjunction with the movement of the door pin member (10) that moves in the direction, the door pin member (10) and the wall surface portion (22a1) reach a position where they do not face each other, and the door pin member (10) can be moved in the closing direction. This is a holding member (20).

  According to the present invention, the wall surface portion (22a1) faces the closing direction side of the door pin member (10) to hold the door in a state in which the movement in the closing direction is impossible, while the door pin member (10) is opened in the opening direction. It is a holding member (20) which enables only movement and whose position changes in conjunction with movement of the door pin member (10) in the opening direction. When the door pin member (10) and the wall surface portion (22a1) reach a position where the door pin member (10) and the wall surface portion (22a1) do not face each other, the door pin member (10) can be moved in the closing direction. That is, in conjunction with the movement of the door pin member (10) in the opening direction, the holding member (20) moves from the position where the wall surface portion (22a1) exists on the movement track in the closing direction of the door pin member (10). By displacing, the obstacle (opposing wall surface) that prevents the door pin member (10) from moving in the closing direction does not exist on the movement track in the closing direction of the door pin member (10). Therefore, the user who wants to close the door does not bend the waist as in the prior art, operate the door pin member with the foot, or do the operation of grasping a predetermined part of the door and pulling in the closing direction, By the “pushing operation” that is a relatively easy operation, the state in which the door pin member (10) cannot be moved in the opening direction, that is, the state in which the door is kept open can be released.

  Further, the opened door is often held at a position close to the wall surface. The direction between the doors held at this position and the wall surface is a narrow path that prevents the inflowing wind from escaping, and the door surface facing the wall surface is subjected to relatively higher wind pressure than the opposite door surface. In a type of door holding device that is operated to release the holding, there is a possibility that a large wind pressure is applied in the same direction and the careless release may occur, and there is a concern that a person may be caught unexpectedly.

  As in the present invention, “holding operation”, which is a relatively easy operation, releases the holding from the state in which the door pin member (10) cannot move in the opening direction, that is, the state in which the door is kept open. If it is a thing, even if a big wind pressure is applied to the same direction, there is no possibility that inadvertent cancellation | release will arise, and it is useful.

Further, according to the present invention, the holding member (20) is moved by being biased by the spring (3), and the wall surface portion (22a1) faces the closing direction side of the door pin member (10) so that the door pin member ( In the state in which the movement in the closing direction of 10) is impossible, the other wall surface part (22d) abuts on the door pin member (10) and the movement in the urging direction is hindered and stopped, and the door pin member (10) from the above state is stopped. Is moved in the opening direction, the contact between the other wall surface portion (22d) and the door pin member (10) is released, so that the door pin member (10) and the wall surface portion (22a1) face each other in the urging direction. Preferably, the holding member (20) described above is characterized in that the door pin member (10) can be moved in the closing direction.

  Moreover, the holding member (20) of the present invention includes an climbing path portion (23) that presses and reduces the door pin member (10) that moves in the opening direction from the above state, and reduces the door pin member (10). It is preferable to use the above-described holding member (20) characterized in that the contact is released by.

Further, the present invention specifically includes a holding member (20) that is movable by being biased by a spring (3), an introduction path portion (21) through which a door pin member (10) that moves in an opening direction passes, An intermediate path portion (22) having a wall surface portion (22a1) that prevents the door pin member (10) from moving in the closing direction while the door pin member (10) that has passed through the introduction path portion (21) passes therethrough, and the intermediate path portion (22). The door pin member (10) that has passed through the door moves in the opening direction and passes, and the climbing portion (23) that reduces the door pin member (10) and the door pin member (10) that passes through the climbing passage portion (23) pass. A holding member (20) having a return path portion (25) that moves in the opening direction, and a door pin member (10) that is pressed against the wall surface portion (21a1) of the introduction path portion (21) is pressed against. After moving in the direction, the introduction path (21) When the passing door pin member (10) reaches the intermediate path portion (22) and the contact is released, the door pin member (10) moves in the biasing direction, and as the door pin member (10) moves in the biasing direction, the door pin member (10) moves to the intermediate path portion (22). The door pin member (10) abuts against the other wall surface portion (22d) of the intermediate path portion (22) and stops, so that the wall surface portion (22a1) faces the door pin member (10) in the closing direction. and becomes in a closing direction movement is impossible state of the door pin member (10), from the state when door pin member (10) passes through the ascending passage section moves the opening direction (23), door pin member (10) and the other The holding member, wherein the contact with the wall surface portion (22d) is released, moves in the urging direction and stops, and the return path portion (25) is positioned on the closing direction track of the door pin member (10). (20) is preferable.

  The present invention is a relatively easy operation without bending the waist, operating the door pin part with a foot, or holding the predetermined part of the door and pulling it in the closing direction as in the prior art. By a certain “pushing operation”, the holding can be released from a state in which the door pin member cannot be moved in the opening direction, that is, a state in which the opening of the door is held.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the drawings showing embodiments for carrying out the present invention.

  As shown in FIG. 1, the present invention provides a door side portion X having a door pin member 10 and a floor that prevents the door pin member 10 from moving in the closing direction (moving in the right direction in the plan view of FIG. 1) and keeps the door open. This is a door holding device including a side portion Y.

(Door side X)
As shown in FIGS. 1 and 2, the door side portion X provided on the door T is a portion that is connected to the door T and is provided on the surface of the door T, and the width direction of the door with respect to the connecting member 15. The holder 14 that can be moved and adjusted in position, the door pin case 13 that can be moved and adjusted in the height direction of the door relative to the holder 14, and can be expanded and contracted in the door height direction in the door pin case 13 And a door pin member 10 attached thereto.

  The connecting member 15 is fixed to the surface of the door T with a screw 15a or the like as shown in FIG.

  As shown in FIG. 2 and the like, the holder 14 includes a proximal end connecting portion 14a and a holder main body portion 14b. The base end connecting portion 14a is slidable by being externally fitted to the connecting member 15, and when being positioned at an arbitrary position, the base end connecting portion 14a is fastened and fixed by a fastening tool 14c. Specifically, it becomes slidable in such a manner that the convex portion 14d formed in the proximal end coupling portion 14a is fitted to the concave portion 15b formed in the coupling member 15.

  The holder main body 14b grips the door pin case 13 in such a manner that it can move in the height direction of the door. Specifically, a screw structure is formed on the cylindrical inner peripheral surface of the holder main body 14b, and a screw structure is also formed on a part of the outer peripheral surface (vertical center portion) of the cylindrical door pin case 13. As a result, the door pin case 13 can be moved in the vertical direction with respect to the holder body 14b. When the door pin case 13 is adjusted, a rotating male tool such as a wrench is inserted into the rotating female portion formed on the upper surface of the door pin case 13 and the door pin case 13 is rotated.

  Inside the cylindrical portion of the door pin case 13, there are provided a door pin member 10 biased by the spring 11 and a retaining member 12 externally fitted to the door pin member 10. When the lower surface of the door pin member 10 is pressed upward, the door pin member 10 moves or contracts upward. When the door pin member 10 is no longer pressed, the door pin member 10 returns to its original length.

  According to this door side part X, construction of a door holding device becomes very easy. That is, in the function of the door holding device, the relative positional relationship between the door pin member 10 on the door side X and the holding member 20 on the floor Y is important. It is not always easy, and there are many cases where it is necessary to redo the construction. In the case of the door side portion X of the present invention, even if it cannot be accurately constructed at an appropriate position, the door pin case 13 can be moved in the height direction of the door, or the holder 14 can be moved as shown in FIG. Since it can be adjusted by moving in the width direction of the door, it is not necessary to redo the construction.

Moreover, even if it can be constructed accurately at the beginning, due to daily use and distortion of the building structure, the relative positional relationship between the door pin member 10 of the door side X and the holding member 20 of the floor Y However, in this case as well, the door side member X of the present invention moves the door pin member 10 in the height and width directions of the door. Therefore, maintenance is easy.

  In addition, as shown in FIG. 4, considering the ease of construction when determining the relative positional relationship between the door pin member 10 and the holding member 20 of the floor side portion Y, the door pin member 10 that moves in the opening direction is first used. A concave portion 26 is formed on the upper surface of the holding member 20 as a mark for the abutting portion.

(Floor side Y)
As shown in FIGS. 5, 6, and 7, the floor side portion Y includes a base 40, a holding member 20 that is slidably attached to the base 40, a spring 3 that biases the holding member 20, and a base 40. And a cover 50 that covers from above.

(Base 40)
As shown in FIG. 7, the base 40 is an integrally molded member, and has a fixing hole 41 for inserting a fixing means such as a screw for fixing to the floor surface.

  As shown in FIG. 7, the base portion 40 functions as a rail for guiding the sliding movement so as to face and approach the inlet portion 46, which is an inclined floor inclined backward, and the front and rear end surfaces 27, 27 of the holding member 20. The stop wall surface 43 that defines the initial position that is the limit position of movement in the biasing direction by the spring 3 by facing the guide wall surfaces 42 and 42 and the left and right end surfaces 28 and 28 of the holding member 20 that slides. And a stop wall surface portion 44 that defines the limit position of the moving range in the direction opposite to the biasing direction by the spring 3 from the initial position.

  Moreover, the base 40 has the recessed part 45 which prescribes | regulates the position of the spring 3, as shown in FIG. The concave portion 45 is formed as a concave portion in an arc shape into which the spring 3 as a spring is fitted. The base 40 has a slit 47 with which a hook formed on the rear end surface side of the holding member 20 (not shown) is engaged, and guides the horizontal movement of the holding member 20 with the hook engaged with the slit 27. Is.

(Cover 50)
As shown in FIG. 7, the cover 50 covering the base portion 40 is an integrally molded product and has slits 51 along the track direction of the door pin member 10. As shown in FIGS. 5 and 6, the cover 50 covers the outline of the base 40 to which the holding member 20 and the spring 3 are attached. The cover 50 and the base portion 40 are connected in such a manner that the inner side surface of the base end wall portion 52 of the cover 50 faces the outer peripheral surface 48 of the base portion 40 and covers from the outside. Even when wax is applied to the floor surface on which the floor side portion X is installed, the cover 50 hardly attaches wax to the holding member 20, so that the wax adheres to the holding member 20 and hinders its movement. There is no fear of such a situation.

(Holding member 20)
As shown in FIG. 7 and the like, the holding member 20 prevents the door pin member 10 from moving in the closing direction and holds the door in an open state.

(Operation of holding member 20)
First, the movement and holding function of the holding member 20 will be described based on the relationship with the door pin member 10.

When the door pin member 10 that moves in the opening direction (upward movement in FIG. 8) presses the inclined wall surface portion 21a1 of the introduction path portion 21 at the initial position shown in FIG. 8A, the holding member 20 at the initial position is spring-loaded. 3 starts to move in the direction opposite to the urging direction (the right direction in FIG. 8), which is the direction in which 3 is reduced. When the door pin member 10 that moves along the inclined wall surface portion 21a1 while pressing the inclined wall surface portion 21a1 reaches the start end of the intermediate path portion 22 where the contact with the curved wall surface portion 21a2 is released (FIG. 8B). )), The movement of the spring 3 in the urging direction is allowed, and the holding member 20 starts to return in the urging direction (the left direction in FIG. 8), which is the direction in which the spring 3 extends, As shown in FIG. 8C, the door pin member 10 is locked to the other wall surface portion 22 d of the intermediate path portion 22. In FIG. 8C, since the wall surface portion 22a1 faces the door pin member 10, the closing direction movement (downward movement in FIG. 8) is impossible, and the door is held open. Then, when releasing the holding of the door T and trying to rotate the door T in the closing direction, the door T is not rotated in the closing direction but is opened by a pushing operation which is a relatively easy operation. Rotate the door in the direction. Although the door pin member 10 is prevented from moving in the closing direction, as shown in FIG. 8D, the door pin member 10 is allowed to move in the opening direction (upward in FIG. 8). The road part on the terminal side of the road part 22 is passed. When the door pin member 10 passes through the end portion of the intermediate road portion 22, the door pin member 10 abuts against the climbing road portion 23 and gradually shrinks, and the door pin member 10 is biased in the direction opposite to the urging direction (the right side surface in FIG. 8). As shown in FIG. 8E, the holding member 20 moves in the urging direction (leftward in FIG. 8) and returns to the initial position, and the door pin member 10 It reaches the summit 24. Since the door pin member 10 located at the top portion 24 does not have an obstacle that disables movement in the closing direction on the closing direction trajectory, the door pin member 10 passes through the return path portion 25 that is the upper surface of the holding member 20 to close the door. Rotation in the direction is possible.

(Structure of holding member 20)
Next, the structure of the holding member 20 will be described.

  As shown in FIG. 7 and the like, the holding member 20 is an integrally molded product, and a passage that is open on the upper surface side is formed. This passage is a passage through which the door pin member 10 passes. The passage includes an introduction path portion 21, an intermediate path portion 22, an ascending road portion 23, and a return path portion 25 in the order in which the door pin member 10 passes.

(Introduction road section 21)
The introduction path portion 21 is a path for introducing the door pin member 10 from the outside of the holding member 10 to the inside as shown in FIG. 9 and the like. The introduction path portion 21 is connected to the intermediate path portion 22 through a straight portion and a bent portion whose direction is changed from the straight portion. Specifically, the start end side of the introduction path portion 21 intersects the track direction of the door pin member 10 (left and right direction in the plan view of FIG. 9 and the like) and an obtuse angle (left and right direction line in the plan view of FIG. 9 and the like) The road portion 21 extends in a direction that forms an angle between the wall surface 21 a 1 of the road portion 21 and the wall surface 21 a 1 of the road portion 21. It is comprised with the road part of the termination | terminus side extended in a direction.

  In detail, as shown in FIG. 9 and the like, the introduction path portion 21 has a wall surface 21 a (21 a 1, 21 a 2) that first contacts the door pin member 10 that moves in the opening direction, and a predetermined interval along the wall surface portion 21 a ( The wall surface portion 21b is opposed to each other with a width slightly larger than the diameter of the door pin member 10, and the road surface portion 21c is located between the wall surface portion 21a and the wall surface portion 21b and is an inclined surface having an upward slope. .

  The wall surface portion 21 a is a portion that first contacts the door pin member 10 that moves in the opening direction, and is connected to an inclined wall surface portion 21 a 1 that extends in a direction intersecting the track direction of the door pin member 10 and the starting end of the intermediate path portion 22. It has a curved wall surface portion 21a2. Specifically, the wall surface portion 21a has an inclined wall surface portion 21a1 that is not opposed to the trajectory direction of the door pin member 10 but is inclined in a direction that intersects the trajectory direction and forms an obtuse angle.

  When the door pin member 10 moving in the opening direction presses the inclined wall surface portion 21a1 of the wall surface portion 21a at the initial position shown in FIG. 9, the holding member 20 existing at the initial position is in the direction in which the spring 3 contracts as shown in FIG. The movement is started (downward in the plan view of FIG. 10 and the like). Then, when the door pin member 10 moving along the inclined wall surface portion 21a1 while pressing the inclined wall surface portion 21a1 reaches the start end of the intermediate path portion 22 where the contact with the curved wall surface portion 21a2 is released, FIG. As shown, the holding member 20 starts to return in the direction in which the spring 3 extends once (towards the upward direction in the plan view of FIG. 11 and the like) once the movement in the direction in which the spring 3 extends is allowed.

(Intermediate road part 22)
When the holding member 20 starts the return movement, the door pin member 10 passes through the intermediate path portion 22. The intermediate path portion 22 includes a straight portion, an L-shaped bent portion that changes direction from the straight portion, and a bent portion. It connects to the climbing road part 23 through the straight line part connected to. Specifically, the start end side of the intermediate path portion 22 intersects with the track direction of the door pin member 10 and has an acute angle (between the horizontal line in the plan view of FIG. 11 and the like and the wall surface portion 22b3 of the intermediate path portion 22). The middle of the intermediate path portion 22 is bent in the track direction from a direction orthogonal to the track direction of the door pin member 10. The end of the intermediate path 22 is a path extending in the track direction of the door pin member 10.

In detail, the intermediate path portion 22 is formed relatively lower than the road surface portion 21c of the introduction path portion 21 and is connected via a step, a wall surface portion 22b (22b1, 22b2, 22b3), a wall surface and the wall portion 22c connected through a part 22b and the bending point C3, partially opposite wall surface portion component 22a (22A1 and 22A2) on the wall portion 22b, the other wall portion connected through the bending point C4 and the wall surface portion 22a 22d.

  The wall surface portion 22b (22b1, 22b2, 22b3) goes straight in the track direction of the door pin member 10 through the straight wall portion 22b1 extending in the track direction of the door pin member 10 (left and right in the plan view of FIG. 11 and the like) and the bending point C1. A straight wall portion 22b2 extending in a direction (vertical direction in the plan view of FIG. 11), an acute angle intersecting the orbit direction (horizontal line in the plan view of FIG. 11 and the like, and a wall surface portion 22b3 of the intermediate path portion 22) And an inclined wall surface portion 22b3 that inclines to form an angle formed between the two surfaces.

Wall portion component 22a (22A1 and 22A2) is formed between the right and left direction line in the plan view of such an obtuse angle (FIG. 11 intersects the track direction of the door pin member 10, the wall portion 22a2 of the intermediate passage portion 22 An inclined wall surface portion 22a2 that is inclined to form an angle in the traveling direction), and a wall surface portion that is connected to the inclined wall surface portion 22a2 via a bending point C5 and extends in a direction orthogonal to the track direction of the door pin member 10. 22a1. The wall surface portion 22a1 faces the opening direction moving side surface (the left side surface in the plan view of FIG. 11 and the like) of the door pin member 10 locked to another wall surface portion 22d described later, and disables the door pin member 10 from moving in the opening direction. . Even if the door pin member 10 to be moved in the closing direction presses the wall surface portion 22a1, the holding member 20 itself cannot move in the left-right direction in the plan view between the guide wall surface portions 42 of the base 40. 20 does not move.

The other wall surface portion 22d is a wall surface extending in a direction (left-right direction in FIG. 11) orthogonal to the direction in which the spring 3 extends (upward in the plan view of FIG. 11 and the like), and is continuous with the wall surface portion 22a1. In particular, an L-shaped wall surface is formed. The door pin member 10 that passes through the intermediate path portion 22 abuts and engages with a biasing opposite direction surface (a lower side surface in the drawing) to stop the movement of the holding member 20 in the biasing direction.

Thus, door pin member 10 passing through the introducing passage 21, the intermediate passage portion 22 is guided along the inclined surface portion 22b3 as well as locking the other wall surface portion 22 d, for facing the wall portion minutes 22a1 Therefore, the door cannot be moved in the closing direction, and the door is kept open.

  Next, the operation when releasing the holding of the door and trying to rotate the door in the closing direction will be described. Instead of rotating the door in the closing direction (impossible to rotate), the door is rotated in the opening direction by a push operation which is a relatively easy operation. The door pin member 10 is prevented from moving in the closing direction (left direction in the figure) at the position shown in FIG. 11, but is allowed to move in the opening direction (right direction in the figure). In accordance with the above operation, the door pin member 10 passes through the end portion of the intermediate passage portion 22.

(Climbing section 23, climbing section 24)
As shown in FIG. 12, the door pin member 10 reaches the ascending road part 23 when passing through the road part on the terminal side of the intermediate path part 22. The ascending road portion 23 is composed of an inclined surface with an upward slope formed between the intermediate road portion 22 and the ascending portion 24. The door pin member 10 that moves in the opening direction and passes through the climbing path portion 23 is gradually pressed against the inclined surface, whereby the spring 11 is contracted, and the door pin member 10 is also moved or contracted upward accordingly. As the door pin member 10 is moved or contracted, the contact between the urging opposite direction surface of the door pin member 10 (the lower surface in the plan view of FIG. 12 and the like) and the climbing path portion 23 is released. 3 moves in the extending direction and returns to the initial position, and the door pin member 10 reaches the crest 24.

  The crest portion 24 is a portion that is recessed slightly lower than the upper surface of the holding member 20, but does not hinder the movement of the door pin member 10 in the closing direction.

  As shown in FIG. 12, the door pin member 10 located at the top portion 24 at the initial position after returning does not have an obstacle that prevents the movement in the closing direction on the closing direction trajectory, and the holding member 20 is on the closing direction track. Since the return path part 25 which is an upper surface is located, the door can be turned in the closing direction.

  With such a holding member 20, the wall portion 22 a 1 faces the closing direction side of the door pin member 10 to hold the door in a state in which the movement in the closing direction is impossible, while the door pin member 10 is moved in the opening direction. Since the holding member 20 changes its position in conjunction with the movement of the door pin member 10 in the opening direction, the door pin member 10 and the wall surface portion 22a1 reach a position where they do not face each other. Thus, the door pin member 10 can be moved in the closing direction. That is, the holding member 20 moves from the position where the wall surface portion 22a1 exists on the movement track in the closing direction of the door pin member 10 to the position where it does not exist in conjunction with the movement of the door pin member 10 in the opening direction. It is possible to make a state in which there are no obstacles that obstruct the movement in the closing direction on the movement trajectory in the closing direction. Therefore, the user who wants to close the door does not bend the waist like the prior art, operate the door pin part with his foot, or do the operation of grasping a predetermined part of the door and pulling in the closing direction, By the “pushing operation” that is a relatively easy operation, the holding can be released from the state in which the door pin member 10 cannot move in the opening direction, that is, the state in which the opening of the door is held.

  In many cases, the opened door is held close to the wall surface, but it is difficult for the wind flowing between the door and the wall surface to escape, and the door surface facing the wall surface is more relative to the opposite door surface. However, a door holding device that operates in the pulling direction to release the holding may cause an inadvertent release, and there is a concern that a person may be caught unexpectedly. If the door pin member 10 cannot be moved in the opening direction by the “pushing operation”, which is a relatively easy operation as in the present invention, that is, if the door is released from being held open, Concerns are alleviated.

(Other embodiments)
FIG. 13 shows another embodiment, which is different only in that a spring S is provided in the passage of the holding member 20. As shown in FIG. 13, the spring S is attached to the terminal end side of the intermediate path portion 22 of the holding member 20. When the spring S abuts against the door pin member 10 passing through the intermediate passage portion 22 and is displaced in the direction opposite to the biasing to allow passage of the door pin member 20, the spring S passes a certain distance while applying a resistance force. Later, a pressing force is applied to the door pin member 10 in the urging direction of the spring S (the right direction in the figure) so that the door pin member 10 can easily move in the direction of the ascending road portion 23 and the ascending portion 24.

  In the other embodiments, the spring S that is separate from the holding member 20 is used, but instead of the spring S, the holding member 20 itself is provided with a portion having a spring action and is integrally molded. It is also possible to do.
