JP 2005-336983 A JP 2007-285117 A

  There are various types of door body moving devices that can automatically move the door body that can be freely opened and closed with respect to the door frame from the half-open state to the closed state or the fully open state. Things exist.

  For example, it is assumed that the apparatus main body having a pivoting arm is provided on a door frame or door frame, and temporary fixing means that can engage the tip of the arm is provided on the door frame or door frame. The apparatus which concerns on patent document 1 and 2 which concerns is mentioned. However, these devices have the following problems.

  The thing of patent document 1 is a thing in which the spring was prepared to the damper, and it serves as both a biasing means and a buffering means. Therefore, there is a problem that the structure becomes relatively complicated. And since it serves as both the biasing means and the buffering means, the point to which the biasing force is applied in the arm coincides with the point for buffering. Therefore, there is a problem that a flexible design cannot be performed.

  The thing of patent document 2 is set as the structure which can arrange | position an apparatus main body to a door body in the vertical direction. The difference from the one described in Patent Document 1 is that the urging means and the buffering means are separated.

  Moreover, the structure described as an Example of patent document 2 pinches | interposes a buffer means from the both sides of an arm. Moreover, since the buffer means is structured to rotate inside the apparatus main body according to the rotation of the arm, there is still room for improvement in terms of downsizing of the apparatus. For example, the door provided on the door frame When it is going to embed in a contact member, there exists a problem that a part of buffer means protrudes from a door contact member in the structure as it is, and cannot be used.

  In view of the above problems, an object of the present invention is to provide a compact door moving device that has a relatively simple configuration and is easy to be incorporated into a door frame.

  In order to solve the above-mentioned problems, the present invention provides that the apparatus main body 2a having the rotating arm 21 is provided in the door body 11 or the door frame 12, and the temporary fixing means 25 to which the arm 21 can be engaged is a door. The door 11 that is provided on the frame 12 or the door body 11 and is arranged so as to be openable and closable with respect to the door frame 12 is automatically operated from the half-open state to the closed state or the fully open state. In the door body moving device that is movable, the device body 2a includes a standby position W corresponding to a half-open state before the automatic movement operation of the door body 11 is started, and a closed state of the door body 11. Alternatively, within the range between the stop position S corresponding to the fully open state, the arm 21 is rotatable about the rotation shaft 21a, and the arm 21 is rotated from the standby position W to the stop position S. , With arm 21 And a buffer means 24 for decelerating the rotation of the arm 21 when the arm 21 rotates from the standby position W to the stop position S. A link member 26 is attached to the link member 26. The link member 26 exerts a force corresponding to the rotation of the arm 21 between at least one of the biasing means 23 and the buffering means 24 and the arm 21. The temporary fixing means 25 is connected so as to transmit, the first abutting part 25a located on the side far from the apparatus main body 2a and the second abutting part 25b located on the side closer to the apparatus main body 2a. The first abutting portion 25a is moved from the standby position W of the arm 21 to the stop position S when the fixing portion 21b which is a part of the arm 21 collides with the closing or opening operation of the door body 11. The second contact portion 25b is urged by the urging means 23 when the arm 21 is rotated from the standby position W to the stop position S. The fixing portion 21b of the arm 21 is in contact with it, thereby moving either the apparatus main body 2a or the temporary fixing means 25 so as to approach the other. Between the contact portion 25b, an arm fixing groove 25c having a space in which the fixing portion 21b of the arm 21 can be coordinated is provided,

When the automatic movement operation of the door body 11 is performed, the fixing portion 21b is held in the arm fixing groove 25c of the temporary fixing means 25, and the arm 21 is biased by the biasing means 23 in that state. Is provided so that the door body 11 is moved.

  In particular, according to the present invention, the buffering means 24 has a structure in which the movable rod 24a protrudes and retracts linearly with respect to the buffering means body 24b. It is attached to a position between 21a and the fixed portion 21b, and the other end is attached to the movable rod 24a of the buffer means 24.

Further, the present invention, the tip of the movable rod 24a in the case of the infested, you characterized in that regulating means 24c for moving parallel to the direction of extension of said cushioning means body 24b is provided.

  The regulating means 24c may be provided with a roller 24c1 provided at the tip of the movable rod 24a and traveling along the inner surface of the casing 20 in the apparatus main body 2a.

  The present invention is applied to a hinged door in which the door body 11 is hinge-supported on the door frame 12, and the door contact member 12 a with which the surface of the door body 11 abuts when the door body 11 is closed is a door frame 12. The apparatus main body 2a is provided so as to constitute a part of the door contact member 12a, covers at least a part of the apparatus main body 2a, and the surface thereof is the door contact member 12a. A cover 12x that is substantially flush with the surface is provided.
  The urging means 23 and the buffer means 24 can be provided separately.

  The urging means 23 and the buffering means 24 are provided substantially in a straight line, and the rotation shaft 21a of the arm 21 is provided with an end 23b far from the buffering means 24 of the urging means 23; It may be provided between the end of the buffer 24 far from the biasing means 23.

  The arm 21 is constantly applied with an urging force from the urging means 23 that rotates to the stop position S. When the arm 21 is at the standby position W, the engagement provided on the arm 21 is applied. The position of the arm 21 is held by engaging the joint portion 22b with the arm position holding means 27 provided on the casing 20 in the apparatus main body 2a. The urging means attaching portion 22a to which the urging force is applied and the engaging portion 22b may be integrally provided on the arm 21.

  One end of the urging means 23 is attached to the arm 21 and the other end is attached to the casing 20 of the apparatus main body 2a, so that the distance from the attachment location of the one end can be changed. A position adjusting means 28 in which the end attachment location is variable may be provided.

  When the door 11 is applied to a hinged door supported by the door frame 12, the rotating shaft 21a of the apparatus body 2a may be provided closer to the hinge than the center of the door 11 in the horizontal direction. The temporary fixing means 25 may be attached to the surface of the door body 11.

  A plate-like body is used as the arm 21, and the arm 21 may be provided with a step 21 c between the base end portion and the tip end portion by bending.

  The present invention has been able to provide a compact door moving apparatus that is relatively simple in configuration and that can be easily incorporated into a door frame.

  An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 are perspective views showing an outline of a usage state of the door moving device of this example. 3-5 is a figure which shows the structure of the door movement apparatus of this example. FIG. 6 is a view showing the periphery of the arm in the door moving apparatus of this example. FIG. 7 is a diagram illustrating a structure of a door moving device according to another embodiment.

[First embodiment]
First, the door 11 is hinge-supported by the door frame 12, that is, the door 11 is configured to be rotatable with respect to the door frame 12 around the hinge, and is surrounded by the door frame 12 in the hinged door. The case where the door moving device is provided so that the door 11 arranged inside is automatically moved from the half-open state to the closed state will be described. Here, the “closed state” indicates a state where the door body 11 is completely closed, the “fully open state” indicates a state where the door body 11 is completely opened, and the “half-open state” indicates that the door body 11 is closed. A state in which the door moving device is in an open state and the door moving device is not operating (including the moment when the operation is started) is shown.

  In addition, the expression of the direction in the following description is basically based on the positional relationship in the state shown in FIGS. 1 and 3 to 5. Specifically, the vertical direction and the horizontal direction are in the state shown in FIG. In the state shown in FIGS. 3 to 5, the direction closer to the door body 11 with respect to the door frame 12 is “front”, and the opposite direction is “rear”. However, there is a case where the upper, lower, left and right directions are described according to the directions shown in the drawings. In addition, the expression of the direction in this description is for facilitating understanding, and the present invention is not limited and understood based on this expression.

  The door moving device 2 of this example has a structure as shown in FIG. 3 and includes an arm 21, an urging means 23, a damper 24, a temporary fixing means 25, and a link member 26. Among them, each of the arm 21, the urging means 23, and the damper 24 is collectively provided in the casing 20, and these constitute the apparatus main body 2a. The apparatus main body 2 a is provided on the door frame 12. The temporary fixing means 25 is provided on the door body 11.

  In this example, a door contact member 12a with which the surface of the door body 11 abuts when the door body 11 is closed is provided as a part of the door frame 12, and the apparatus main body 2a constitutes a part of the door contact member 12a. Provided. As shown in FIG. 2, the door contact member 12 a of this example is integrated with the door frame 12 by being partially fitted into an attachment groove 12 b provided on the surface of the door frame 12. When the apparatus main body 2a is provided on the door frame 12, the door contact member 12a disposed at the upper part of the door contact member 12a provided on at least a part of the inner peripheral side of the door frame 12 is cut by a certain interval. The apparatus main body 2a is inserted into the cut-out mounting groove 12b in place of the cut door stop member 12a. Thereby, the door contact member 12a which is not cut | disconnected and the said apparatus main body 2a inserted can be integrated in the door frame 12. FIG. That is, the apparatus main body 2a is arrange | positioned at the door frame 12 so that some door stop members 12a may be comprised. The apparatus main body 2a fitted in this example is fixed to the bottom surface of the mounting groove 12b by screws with mounting allowances 20a provided at both ends of the casing 20.

  Since the apparatus main body 2a is fitted as described above, the door frame 12 need not be processed on-site as long as a door cut member 12a is cut in advance. There is a merit that can be simplified.

  In addition, as shown in FIG. 1, the apparatus main body 2a covers at least a part of the apparatus main body 2a so that the surface of the apparatus main body 2a constitutes a part of the door contact member 12a as described above, and the surface is the door contact member 12a. A cover 12x is provided which is substantially flush with the surface. Thereby, only a part of the arm 21 protrudes from the door stop member 12a. In this example, the lower surface, the front surface, and the rear surface of the apparatus main body 2a are covered. Therefore, the presence of the apparatus main body 2a can be made inconspicuous by the cover 12x, and there is an advantage that the design can be made excellent.

  The attachment of the apparatus main body 2a may be performed by cutting out the door contact member 12a as described above, or by cutting out the door contact member 12a and embedding the apparatus main body 2a in the hollowed out space. The formation of the mounting groove 12b is not essential in the present invention, and the door contact member 12a may be mounted on the flat surface of the door frame 12 with an adhesive, a nail, a screw, or the like. In this case, the apparatus main body 2a is also mounted on the flat surface of the door frame 12.

[casing]
The casing 20 in this example is a vertically long cylindrical body. As described above, the casing 20 is arranged in the horizontal direction when installed on the door frame 12. Thereby, it is possible to embed the apparatus main body 2a naturally without substantially protruding from the door stop member 12a. Moreover, it becomes difficult to receive the restriction | limiting of the dimension of the width direction about the attachment object of the apparatus main body 2a by setting it as such a slim shape. Therefore, for example, since the apparatus main body 2a can be embedded in the upper end surface of the door body 11, or can be embedded in a door frame or door body of a sliding door, the degree of freedom of attachment of the apparatus main body 2a can be increased.

[arm]
Next, the arm 21 will be described. The arm 21 of this example uses a single plate-like plate that is substantially band-shaped, and the tip side (the upper end side in FIG. 3) projects from the casing 20 as shown in FIG. . On the other hand, as shown in FIG. 3, the base end side (the lower end side in FIG. 3) is attached to the casing 20 via a rotating shaft 21a.

  In this example, since the apparatus main body 2a and the temporary fixing means 25 are provided on the “hanging base”, the arm 21 is stopped from the standby position W corresponding to the angle with respect to the door frame 12 for automatically closing the door body 11. The moving distance to the position S can be reduced as compared with the case where the “door” is provided. Therefore, the arm 21 of this example has a relatively short length.

  In addition, the state provided in the above “hanging base” refers to a state in which the rotation shaft 21 a of the arm 21 in the apparatus main body 2 a is located closer to the hinge than the center in the horizontal direction of the door body 11. The state provided at the “door tip” indicates a state in which the rotation shaft 21 a of the arm 21 in the apparatus main body 2 a is located farther from the hinge than the center of the door body 11 in the horizontal direction. In the embodiment shown in FIG. 7, the apparatus main body 2a and the temporary fixing means 25 are provided at the “door”.

  The arm 21 is rotatable within a predetermined range around the rotation shaft 21a. In this example, the position closer to one end of the rotation range of the arm 21 is the standby position W (state shown in FIG. 3), and the position closer to the other end is the stop position S (state shown in FIG. 5). Each corresponds to the half-open state and the closed state of the door body 11. In other words, when the tip end side of the arm 21 is on the upper side in FIG. 3 with respect to the rotation shaft 21a (that is, the state in which the arm 21 protrudes forward with respect to the casing 20), When the vehicle is on the right side (that is, the state where the arm 21 is housed in the casing 20), the stop position S is set. The arm 21 is rotatable at least within the above range. In contrast to this example, when the door moving device is used to fully open the door 11, the standby position W corresponds to the half-open state of the door 11, and the stop position S is the fully open state of the door 11. It will correspond to.

  In this example, a step 21 c is provided between the proximal end portion and the distal end portion of the arm 21. The step 21c is formed by bending a plate-like arm 21 into a substantially Z-shape in the middle as shown in FIGS. More specifically, the step 21c is formed so that the base end side is located above and the distal end side is located below across the step 21c when the apparatus main body 2a is provided on the door frame 12. As a result, as shown in FIG. 1, only the portion near the tip of the arm 21 protrudes from the slit provided on the lower surface of the cover 12x, and the presence of the arm 21 is as inconspicuous as possible, and the design surface is excellent. And can.

  The shape of the arm 21 is not limited to the one in this example. For example, the arm 21 may be attached to the door 11 such as a rod shape or a curved shape as in the other embodiments shown in FIG. Implementation in various forms according to the design of the door moving device such as the range of the moving operation is possible.

  Next, as shown in FIGS. 1 and 2, a cylindrical fixing portion 21 b is provided on the distal end side of the arm 21 in this example so as to protrude downward from the surface of the arm 21. As shown in FIGS. 4 and 5, the fixing portion 21 b is held by a temporary fixing means 25 provided in the door body 11 (more specifically, an arm fixing groove 25 c provided in the temporary fixing means 25). As a result, the door body 11 can be automatically closed by being pulled by the biasing force of the biasing means 23.

  The fixing portion 21b of the present example includes a shaft portion 21b1 and a roller portion 21b2 that is rotatable with respect to the shaft portion 21b1, and as shown in FIG. When positioned in the arm fixing groove 25c of the temporary fixing means 25, the roller part 21b2 can rotate with respect to the first contact part 25a and the second contact part 25b of the temporary fixing means 25, so that it is temporarily fixed. The fixing portion 21b can be moved with a small resistance with respect to the means 25. In this example, the fixing portion 21b is provided at the tip of the arm 21, but the fixing portion 21b may be formed at a place other than the tip, such as in the middle of the arm 21.

[Base block]
Here, as described above, the base end block 22 is attached to the base end portion of the arm 21 which is a plate-like body so as to be in contact with the front and back directions of the arm 21. The base end block 22 is provided with a biasing means mounting portion 22a having a groove for hooking one end side 23a of the biasing means 23. In this example, since the two urging means 23 are provided, the urging means attaching portions 22a are also provided at two places.

  The base block 22 is integrally provided with an engaging portion 22b for the arm position holding means 27 described below, together with the biasing means attaching portion 22a. Conventionally, these two parts have been provided separately, but in this example, since they could be combined into one part, the number of components can be reduced. As shown in FIG. 6, the engaging portion 22 b has a shape protruding in the proximal direction of the arm 21. The protruding shape of the engaging portion 22b is a shape with which the curved portion 27a of the arm position holding means 27 can come into contact.

  In this example, the plate-like arm 21 and the block-like base end block 22 are separately formed and integrated by caulking. However, when the arm 21 is made of, for example, casting or hard resin, In this case, the arm 21 and the base end block 22 may be originally formed as one component.

[Energizing means]
Next, the biasing means 23 will be described. The urging means 23 urges the arm 21 to rotate from the standby position W toward the stop position S about the rotation shaft 21a. In this example, it is implemented as two coil springs provided in parallel in the casing 20, and the urging force by the tensile force is applied to the proximal end portion of the arm 21. One end side 23 a of the urging means 23 is attached to the urging means attachment portion 22 a of the base end block 22 attached to the arm 21, and the other end side 23 b is attached to the casing 20.

  In the present invention, a general spring can be used as the biasing means 23 as described above. That is, since the urging means 23 and the damper 24 can be provided separately, as shown in Patent Document 1, a structure in which the spring is loaded into the damper serves as both the urging means and the buffering means. However, there is no need to use a relatively complicated dedicated product. And since the general-purpose product of a linear motion damper can be utilized also about the damper 24 mentioned later, this can simplify the structure of the apparatus main body 2a, and can contribute to the manufacturing cost reduction of an apparatus. However, the present invention does not completely exclude the use of the biasing means and the buffering means as shown in Patent Document 1, for example, when there is a demand for downsizing of the apparatus main body 2a. You may use what served as a biasing means and a buffer means.

  As the urging means 23, two coil springs are used in this example. However, this is not limited as long as the condition of the shape of the apparatus main body 2a permits, for example, one or three or more coil springs. Or other types of springs such as spiral springs attached to the rotating shaft 21a, or elastic resins such as rubber may be used. Further, the place where the urging means 23 is attached to the arm 21 and the casing 20 is not limited. Moreover, it is good also as what biases the arm 21 using the extension of a spring contrary to this example.

[Position adjustment means]
In this example, the urging force of the urging means 23 can be adjusted by providing the position adjusting means 28 on the other end 23 b side of the urging means 23. In the position adjusting means 28, the attachment location of the other end 23b is variable so that the distance from the attachment location of the one end 23a of the biasing means 23 can be changed. Specifically, as shown in FIG. 3, the casing 20 is provided with a locking groove 28b in which a plurality of branch grooves 28c are branched. Each of the branch grooves 28c is formed so that the distance from the urging means mounting portion 22a of the arm 21 is different. The movable shaft 28a to which the other end 23b of the coil spring 23 is attached is arranged in the branch groove 28c. Thereby, the initial length of the coil spring 23 can be changed. By doing so, the moving speed of the arm 21 can be adjusted, and the slowness of the closing speed of the door 11 can be adjusted accordingly.

  The position adjusting means 28 is not limited to the structure described above, and a slide member 28c that is movable in the longitudinal direction in the casing 20 is provided as in another embodiment shown in FIG. Alternatively, the position of the slide member 28c may be adjusted by the adjusting screw 28d, and various structures can be used. In some cases, the position adjusting means 28 may be provided on the one end 23a side of the urging means 23.

  The urging force of the urging means 23 in this example is always applied to the arm 21 in the direction in which the arm 21 is rotated to the stop position S. The arm 21 is held at the standby position W by engagement of arm position holding means 27 (in this example, a leaf spring attached to the casing 20) provided in the apparatus main body 2a. This state is maintained until the roller portion 21b2 of the arm 21 collides with the first contact portion 25a in the temporary fixing means 25. When the collision occurs, the arm position holding means 27 and the arm 21 are disengaged, and the arm 21 starts rotating to the stop position S by the urging force of the urging means 23.

  Unlike this example, means for supporting the arm in the apparatus described in Patent Document 2 may be used. This means is that the arm 21 is held at the standby position W by the urging force of the urging means 23 depending on whether the urging means mounting portion 22a is closer to the front or rearward with respect to the rotating shaft 21a ( It is determined whether to turn to the stop position S (in the case of the front side) (in the case of the front side). In this case, the arm 21 is held at the standby position W when the urging means mounting portion 22a is closer to the front with respect to the rotation shaft 21a. Then, when the roller portion 21b2 of the arm 21 collides with the first abutting portion 25a of the temporary fixing means 25, the urging means attaching portion 22a moves toward the rear with respect to the rotating shaft 21a, and accordingly, The arm 21 automatically starts to rotate by the urging force of the urging means 23.

[Damper (buffer means)]
Next, the damper 24 will be described. The damper 24 acts as a buffering means for decelerating the rotation operation of the arm 21 when the arm 21 rotates from the standby position W toward the stop position S by the urging force of the urging means 23. In this example, a direct acting damper is used as the damper 24. That is, the movable rod 24a is structured so as to appear and disappear linearly with respect to the buffer means body 24b. The buffer means main body 24b is arranged in parallel to the vertically long casing 20. A tip of a movable rod 24 a provided on the damper 24 is connected to one end of a link member 26 (described later) connected to the arm 21, whereby the arm 21 is connected to the damper 24 via the link member 26. And power is transmitted. Similarly to the urging means 23 described above, the damper 24 may be adjustable in the closing speed of the door 11 by adjusting the buffering capacity with a screw or the like.

  As shown in FIGS. 4 and 5, the fixing portion 21 b of the arm 21 is held in the arm fixing groove 25 c of the temporary fixing means 25 provided in the door frame 12, and the arm 21 is moved to the urging means 23. By being biased, the arm 21 rotates from the standby position W toward the stop position S. Accordingly, the door body 11 to which the apparatus main body 2a is attached is moved and closed so as to be attracted to the door frame 12. During this closing operation, the rotation operation of the arm 21 from the standby position W (upper direction shown in FIG. 3) to the stop position S (right side) is decelerated by the buffering action of the damper 24 via the link member 26. The Therefore, the movement of the door body 11 is also decelerated, and the opening side end surface 11a of the door body 11 does not suddenly collide with the door contact member 12a, and the closing operation can be performed quietly and reliably. Further, since the arm 12 does not move suddenly due to the presence of the damper 24, the door 11 does not bounce against the door frame 12.

  In this example, as shown in FIG. 3 and the like, the urging means 23 and the damper 24 are provided on a substantially straight line, and the rotating shaft 21 a of the arm 21 is provided with the damper 24 of the urging means 23. It is provided between the end portion far from the urging means 23 of the damper 24 and the end portion far from the urging means 23 of the damper 24. Since the casing 20 that accommodates both of them is provided in a substantially straight line in this manner, the shape of the casing 20 can be made slim, and the degree of freedom of attachment of the apparatus main body 2a can be increased. Specifically, as described above, it is possible to adopt a structure in which the apparatus main body 2a is fitted into the door stop member 12a. Therefore, on-site processing of the door frame 12 can be made unnecessary, and the on-site man-hour can be reduced. Further, by arranging the urging means 23 that exerts the urging force on the arm 21 and the damper 24 that absorbs the urging force so as to sandwich the arm 21, both are positioned in the same direction with respect to the arm 21. However, designing from a mechanical viewpoint becomes relatively easy.

[Link member]
Next, the link member 26 will be described. The link member 26 is a single strip-like plate-like body, and the distal end side (the upper left end side in FIG. 3) is positioned between the rotating shaft 21a of the arm 21 and the fixed portion 21b. It is pivotally attached. In this example, the arm 21 is attached to the base end side with respect to the step 21c. The base end side (the right lower end side in FIG. 3) is rotatably attached to the tip of the movable rod 24a in the damper 24. In this example, it is attached to the tip of the movable rod 24a, but is not limited thereto, and may be attached to another position. The link member 26 is also provided with a step similar to the arm 21, and the vertical position shift between the arm 21 and the tip of the movable rod 24 a is adjusted by this step. By attaching the link member 26 between the rotation shaft 21a and the fixed portion 21b of the arm 21 as described above, the force accompanying the rotation of the arm 21 can be effectively transmitted to the damper 24. Can be buffered.

  As described above, in the present invention, the arm 21 and the damper 24 are not directly connected but are connected via the link member 26. For example, in the conventional structure of this type of device such as the device described in Patent Document 2, the tip of the damper is swung in accordance with the rotation of the arm. On the other hand, in the present invention, by providing the link member 26 between the arm 21 and the damper 24, the force due to the rotation of the arm 21 is applied from the arm 21 to the damper 24 without causing the damper 24 to swing. It can be transmitted and can exhibit a buffering effect.

  Thus, the damper 24 in the present invention does not swing with respect to the casing 20, and the movable rod 24a only appears and disappears linearly with respect to the buffer means body 24b. Therefore, since it is not necessary to design the casing 20 in anticipation of the swinging motion as in the conventional case, the apparatus main body 2a can be made compact.

  The damper 24 only needs to be fixed to the casing 20, but the movable rod 24a may bend when the cushioning means main body 24b alone is fixed. Restricting means 24c for moving in parallel with the extending direction of 24b is provided.

  In this example, the restricting means 24c is composed of a roller 24c1 and a roller running surface 24c2. The roller 24c1 is rotatably provided at the tip of the movable rod 24a. A part of the inner surface of the casing 20 facing the roller travel surface 24c2 is used as it is, and the roller 24c1 travels along the roller travel surface 24c2. Thereby, the movable rod 24a provided with the roller 24c1 moves in parallel to the roller running surface 24c2. As described above, since the buffer means main body 24 b is arranged in parallel to the vertically long casing 20, the movable rod 24 a also moves in parallel to the casing 20. In this example, since the roller 24c1 is employed, there is an advantage that the resistance of movement can be reduced and the wear of parts can be reduced as compared with the configuration in which the movement of the movable rod 24a is regulated by sliding.

  The restricting means 24c is not limited to the roller of this example. For example, a member that sandwiches the movable rod 24a or surrounds the periphery of the movable rod 24a is provided. May be regulated and can be implemented in various forms.

  In this example, the link member 26 is provided between the arm 21 and the damper 24. However, since the urging means 23 is also swung, the link is provided between the arm 21 and the urging means 23. The member 26 may be provided.

[Arm position holding means]
In order to keep the arm 21 at the standby position W as described above, the casing 20 is provided with the arm position holding means 27. As shown in FIG. 3, the arm position holding means 27 is engaged with a base block 22 in which a curved portion 27 a which is a part of the arm position holding means 27 is attached to the arm 21 when the arm 21 is in the standby position W. The arm 22 can be engaged and the arm 21 can be held at the standby position W.

  In this example, a leaf spring is used as the arm position holding means 27, and a base end side 27 b that is the left end side shown in FIG. 6 is fixed to the casing 20. The leaf spring 27 has a curved portion 27 a formed so as to protrude toward the arm 21. The specific shape of the arm position holding means 27 in this example is as follows. When the arm 21 is at the standby position W as shown in FIG. And is bent into an inverted U shape so as to protrude upward at the tip end side, and this bent portion becomes a curved portion 27a. The curved portion 27 a is engageable with the engaging portion 22 b in the base end block 22.

  The form of the position holding part 26a and the arm position holding means 27 is not limited to the one in this example as long as the arm 21 can be held at the standby position W, and can be implemented with various modifications. . For example, an elastic member made of resin or the like is brought into contact, or a claw is provided at the tip of a metal fitting that is rotatable with respect to the casing 20, and the arm 21 is held by the claw. It is also possible to use no biasing force, such as by fitting between a recess and a protrusion, by friction, or by using a magnet.

  Further, even if the biasing force is used, it is not limited to the one that presses the arm 21 as in the leaf spring of this example, and the arm 21 is pulled by pulling the arm 21 by using a coil spring or the like. It may be one that can be held.

[Temporary fixing means]
The temporary fixing means 25 is attached to the surface of the door body 11 on the side facing the door contact member 12a in this example. Thus, by setting it as the structure attached to the surface of the door body 11, attachment to the door body 11 can be simplified and field work can be simplified. However, the temporary fixing means 25 may be embedded in the door body 11. In such a case, since the temporary fixing means 25 can be made inconspicuous, the design can be improved.

The temporary fixing means 25 includes a door body mounting bracket 25x (not directly shown) and a temporary fixing means body 25y attached to the door body mounting bracket 25x. As shown in FIG. 3, a long hole 25d is formed in the bottom surface of the temporary fixing means main body 25y. By fixing the screw to the door body mounting bracket 25x through the long hole 25d, a horizontal direction with respect to the door body 11 is obtained. It is possible to adjust the mounting position of the temporary fixing means 25. Therefore, it is possible to easily adjust the position of the apparatus main body 2a at the site, and it is not necessary to re-open a hole in the door 11 for the readjustment of the position.
The temporary fixing means 25 includes a first contact part 25a located on the side far from the apparatus main body 2a and a second contact part 25b located on the side closer to the apparatus main body 2a.

  The first abutting portion 25a rotates from the standby position W of the arm 21 to the stop position S when the fixing portion 21b of the arm 21 collides with the closing or opening operation (in this example, the closing operation) of the door body 11. It is a part for starting movement. Specifically, the engagement between the engagement portion 22b of the base end block 22 and the bending portion 27a of the arm position holding means 27 is released by the collision, and the urging force of the urging means 23 is always applied as described above. The arm 21 starts to turn to the stop position S.

  In this example, when the arm 21 rotates from the standby position W to the stop position S, the second contact portion 25b contacts the fixed portion 21b of the arm 21 biased by the biasing means 23. This is the part for moving the temporary fixing means 25 so as to approach the apparatus main body 2a. Contrary to this example, when the apparatus main body 2a is attached to the door 11 and the temporary fixing means 25 is attached to the door frame 12, the apparatus main body 2a approaches the temporary fixing means 25 contrary to the above. Will be moved to.

  Between the first contact portion 25a and the second contact portion 25b, an arm fixing groove 25c having a space in which the fixing portion 21b of the arm 21 can be arranged is provided. In this example, the arm fixing groove 25 c is a linear groove that is open at the top, has a curved entrance, and is formed in parallel with the surface of the door 11 on the back side. The width dimension (inner dimension) of this groove is slightly larger than the diameter dimension of the roller part 21b2 so that the fixing part 21b of the arm 21 can move in the arm fixing groove 25c without any trouble.

  When the automatic movement operation of the door 11 is performed, the fixing portion 21b of the arm 21 is held in the arm fixing groove 25c, and the arm 21 rotates in response to the urging force of the urging means 23 in that state. Thereby, the door 11 moves to the stop position S.

  Here, for example, in the configuration of this example, the arm 21 should be in the standby position W when the door 11 is opened, but the arm 21 may be housed in the casing 22 for some reason. obtain. In such a case, in this example, the arm 21 must be pulled out by hand. For example, a return portion for hooking a part of the arm 21 on the surface of the temporary fixing means 25 is provided, and the door body 11 is moved. A structure may be adopted in which the arm 25 is pulled out from the casing 22 by closing once and hooking a part of the arm 21 to the return portion and opening the door body 11 again.

[Second Embodiment]
Next, an embodiment having a form different from the above embodiment as shown in FIG. 7 will be described. Only the differences from the above embodiment will be described here.
In this embodiment, the apparatus main body 2a and the temporary fixing means 25 are provided at the "door tip", that is, at a position far from the hinge. The temporary fixing means 25 is embedded in the door body 11.

  In this example, the arm 21 is curved. Moreover, since it is provided at the “door tip”, the movement distance from the standby position W to the stop position S of the arm 21 corresponding to the angle with respect to the door frame 12 for automatically closing the door body 11 is expressed as “hanging source”. Therefore, the arm 21 is longer than that in the above embodiment.

  In this example, the entrance of the arm fixing groove 25c of the temporary fixing means 25 is widened so that the tip of the arm 21 can be easily received. A retracting recess 25z is provided on the surface of the temporary fixing means 25. As described in the above embodiment, even if the arm 21 is housed in the casing 22 for some reason, the fixing portion 21b at the tip of the arm 21 is accommodated in the recess 25z. The door 11 can be closed. In this case, however, automatic closing is not performed.

  In this example, the adjustment of the initial length of the urging means 23 by the position adjusting means 28 is performed by a screw. Specifically, as shown in FIG. 6, a slide member 28c that can move inside the casing 20 is provided, and the position of the slide member 28c is adjusted by an adjusting screw 28d.

[Other examples]
The present invention is not limited to the two types described above, and can be implemented with various modifications.
First, the closed state or the open state of the door body 11 can be variously changed and set depending on circumstances. For example, in order to allow ventilation or to allow pets such as dogs and cats to pass therethrough, they may be set so as to be closed while maintaining a predetermined gap without being fully closed even when closed.

Further, two door moving devices may be used for one door 11. In this case, one door moving device is activated when the door 11 is about to close, and the other door moving device has the same structure as the one door moving device. Thus, it is possible to automatically open the door 11 from the predetermined open state to the fully open state. That is, in this case, the arm 21 for performing the closing operation protrudes from the surface on one side of the door body 11, and the arm 21 for performing the opening operation protrudes from the surface on the other side. Of the temporary fixing means 25, the one in charge of the closing operation is attached to the door frame 12, and the one in charge of the opening operation is attached to a fitting at a corresponding position in the fully open state of the door body 11.
In the above description, the case where the longitudinal direction of the apparatus main body 2a is arranged in the horizontal direction is shown, but the longitudinal direction of the apparatus main body 2a may be arranged in the vertical direction.

  In the above, although the example which applied the door body moving apparatus to the hinged door was demonstrated, this invention is not limited to this, The door body 11 slides to a horizontal direction (left-right direction) with respect to the door frame 12. FIG. You may apply to the sliding door which is a type. As described above, since the door body moving device according to the present invention is a device whose body 2a is slimmed, it can be attached to the door body 11 and the door frame 12 even when applied to a sliding door. Has the advantage that it can be made easier than conventional devices of the same kind. Moreover, you may apply a door body moving apparatus to a folding door.
