Summary of the Invention

Problems to be Solved by the Invention

[0004] There are various opening devices equipped with an anti-sway function, and a vertical sliding window can be cited as an example. A vertical sliding window is an opening device commonly found in public facilities and hotels, but users who are not accustomed to anti-sway may not understand how to lock or unlock it. In addition, the locking methods of anti-sway devices vary from product to product. Even users who are accustomed to anti-sway operations in general may have trouble understanding the operations when the product changes. As described above, anti-sway devices have been inconvenient for users. An object of the present invention is to provide an opening device with an anti-sway function that is user-friendly.

Means for Solving the Problems

[0005] The present invention includes a frame 2 and a door 3 supported by the frame. The frame has an arm 51. The arm 51 is provided with a guide groove 511 that guides a protrusion 441A provided on the door 3 and has a recess 512 into which the protrusion 441A fits to hold the door 3 in an open state at a predetermined angle. The door 3 has a member (6·7) that can move forward and backward with respect to the arm 51. The member that can move forward and backward is provided with arm contact portions (621·731). The problem is solved by providing an opening device 1 characterized in that the protrusion 441A fitted in the recess 512 can be restricted by the arm contact portions (621·731) so as not to come out of the recess 512.

Effect of the Invention

[0006] The usability of the opening device of the present invention has been improved.

Embodiments for Carrying Out the Invention

[0008] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same reference numerals in different figures indicate parts having the same function, and duplicate descriptions in each figure will be omitted as appropriate.

[0009] [Example 1] Example 1 is an example using the vertical sliding window 1 as the opening device. Fig. 1 is an explanatory diagram of the vertical sliding window 1 (opening device) in the closed state according to Example 1, and Fig. 1(A) is an internal view of the vertical sliding window 1 (opening device) in the closed state. The frame 2 of the vertical sliding window 1 is a framework composed of an upper frame 23, a lower frame 24, a door tip side vertical frame 21, and a suspension side vertical frame 22. The housing 4 of the vertical sliding window 1 is composed of an upper housing 41, a lower housing 42, a suspension side vertical housing 43, and a door tip housing 44. The shoji with the facing material 31 fitted into the housing 4 is supported so as to be slidable outwards. Although not shown in the drawings, in the vertical sliding window 1 (opening device) of the first embodiment, the friction stay is provided between the hanging side vertical frame 22 of the lower frame 24 and the lower surface of the lower frame 42. Further, in the vertical sliding window 1 (opening device) of the first embodiment, a friction stay is also attached between the hanging side vertical frame 22 of the upper frame 23 and the upper surface of the upper frame 41, and the door 3 is supported by a pair of friction stays so as to be openable and closable.

[0010] (Handle) The handle 6 is attached to the door tip frame 44 via a rotating shaft 61 provided in the horizontal direction. The handle 6 is configured to be rotatable clockwise as shown by the arrow in Fig. 1(A), and Fig. 1(B) is an explanatory diagram of the direction of the handle 6 when the door 3 is closed and locked so that the door 3 cannot be opened. The protruding portion 62 of the handle 6 (member capable of moving forward and backward) in the fully closed state protrudes from the door tip frame 44 toward the inner side viewing surface 212 of the door tip side vertical frame, and locks the outward-opening door 3 so that it cannot be opened. Fig. 1(C) is an explanatory diagram of the direction of the handle 6 when the lock of the door 3 is released (during opening and closing). The handle 6 is rotated around the rotating shaft 61, and the lock is released when the protruding portion 62 is within the width of the inner side viewing surface 442 of the door tip frame.

[0011] (When the door is closed) Fig. 2 is an explanatory diagram of the arm 51 in the closed state. Fig. 2(A) is an internal view of the vertical sliding window 1 (opening device) in the closed state. Fig. 2(B) is a cross-sectional view near the handle 6 (member capable of moving forward and backward) between B-B in Fig. 2(A). Fig. 2(C) is a cross-sectional view between A-A in Fig. 2(A). As shown in Fig. 2(B), on the upper side of the guide groove 511, a closing engagement portion 513 that is recessed toward the indoor side is provided. When the door 3 is completely closed, it is configured such that the protrusion 441A engages with the closing engagement portion 513. As described above, when the protrusion 441A engages with the closing engagement portion 513 (i.e., at the time of closing), the lock is engaged by moving the handle 6 to the locked state side shown in Fig. 2(C). When the door is closed, the door end frame 44 cannot move further inward because there is a frame 2 on the indoor side. The anti-disengagement member 441B is a disk with a diameter slightly larger than the width of the guide groove 511. It is attached to the tip side of the protrusion 441A and is a member that prevents the protrusion 441A from coming out of the guide groove 511. The enlarged view of the frame C in Fig. 2 is an enlarged view of the state where the door 3 is locked so that the shoji door cannot be opened. By rotating the handle 6 around the rotation axis 61 and protruding the protruding portion 62 toward the door end side vertical frame 21 side, the lock is engaged. The protruding portion 62 engages the lock by contacting the handle receiver 212A attached to the indoor side finding surface 212 of the door end side vertical frame. As shown in Fig. 2(C), the handle receiver 212A is a member with sufficient thickness for the protruding portion 62 to contact firmly. By operating this handle 6, the door 3 is locked.

[0012] (Arm) The arm 51 is a main component of the sway prevention mechanism 5 described later. As shown in Fig. 2(B), the upper end of the arm 51 is rotatably attached via a rotation shaft 52 attached to the prospective surface 211 of the door end side vertical frame. The arm 51 is pivotally supported so as to rotate in the direction of the arrow around the rotation shaft 52 as the door 3 opens. The arm 51 has a guide groove 511, and the guide groove 511 is provided from the middle to the lower end of the arm 51. The hatched members in Fig. 2(C) are members arranged on the door 3 side, such as the door end frame 44 and the handle 6, and are members that move when the door 3 is opened and closed. The non-hatched member is the door end side vertical frame 21, which is a member that does not move. Since the protrusion 441A is fixed to the prospective surface 441 of the door end frame, the protrusion 441A also moves when the door 3 moves. As shown in Fig. 2(B), the protrusion 441A moves guided by the guide groove 511. As the door 3 opens, the protrusion 441A moves toward the lower end of the guide groove 511. As shown in the enlarged view of Fig. 2(B), a pair of disk-shaped anti-disengagement members 441B are attached to sandwich the arm 51 with respect to the protrusion 441A, preventing the protrusion 441A from coming out of the guide groove 511.

[0013] (State of opening the door) Figure 3 is an explanatory view of the arm 51 during the opening and closing operation. Figure 3(A) is an internal view of the vertical sliding window 1 (opening device) during the opening and closing operation. Figure 3(B) is an explanatory view of the direction of the handle 6 (a member that can move forward and backward) during the opening and closing operation. The handle 6 during the opening and closing operation is rotated in the direction shown in Figure 3(A) and Figure 3(B). The protrusion 62 near the rotation axis 61 of the handle 6 shown in these figures is accommodated within the inner surface 442 of the door leading edge frame chamber side, and is at a position where the lock of the door 3 is released.

[0014] Figure 3(C) is an explanatory view of the arm 51 during the opening and closing operation. Figure 3(D) is an explanatory view showing the relationship between the door 3, the arm 51, and the frame 2 during the opening and closing operation. The protrusion 441A fixed to the expected surface 441 of the door leading edge is guided into the guide groove 511 of the arm 51 as the door 3 moves. When closed, the arm 51 that was hanging downward rotates about the rotation axis 52 so as to gradually become closer to horizontal as the door 3 is opened. The protrusion 441A guided into the guide groove 511 advances toward the lower end of the guide groove 511 having the recess 512. Note that the member labeled (5) in Figure 3 is the main member of the anti-sway mechanism 5.

[0015] (Locked state of the anti-sway mechanism) Figure 4 is an explanatory view when the anti-sway mechanism 5 is locked. Figure 4(A) is an explanatory view of the position of the door 3 when the anti-sway mechanism 5 is locked, and Figure 4(B) is an explanatory view of the direction of the handle 6 when the anti-sway mechanism 5 is locked. Comparing Figure 4 in which the anti-sway mechanism 5 is in the locked state with Figure 3 during the opening and closing operation, only the direction of the handle 6 is different. The handle 6 can move forward and backward toward the arm 51 by rotating about the rotation axis 61. In this way, both the handle 6 and the protrusion 62 function as members that can move forward and backward of the anti-sway mechanism 5. As shown in Fig. 4(B), when the sway prevention mechanism 5 is in the locked state, the handle 6 (a member that can move forward and backward) is rotated counterclockwise by 90° from the position during the opening and closing operation around the rotation axis 61. By this operation, the protruding portion 62 (a member that can move forward and backward) protrudes in a direction with the arm 51 from the inner finding surface 442 of the door end frame chamber. Fig. 4(D) shows a state where the protruding portion 62 (a member that can move forward and backward) moves forward and backward with respect to the arm 51 and protrudes toward the arm 51.

[0016] As shown in Fig. 4(C), as the handle 6 (a member that can move forward and backward) rotates, the arm contact portion 621 on the protruding portion 62 (a member that can move forward and backward) protruding toward the arm 51 comes into contact with the contact surface 53 provided at the lower part of the arm 51. Further, by rotating the handle 6 (a member that can move forward and backward), the protrusion 441A fitted in the recess 512 of the guide groove 511 is pressed toward the recess 512 and the locking is completed. The arm contact portion 621 restricts the protrusion 441A fitted in the recess 512 so that it does not come out of the recess 512, and the sway prevention mechanism 5 is locked.

[0017] Even if the door 3 is swayed by strong wind, it is held in the state of being opened at a predetermined angle via the sway prevention mechanism 5 (arm 51), so it cannot move either in the closing direction or in the opening direction.

[0018] (Effect of Example 1) The handle 6 (a member that can move forward and backward) of Example 1 also serves as the locking mechanism for the door 3 of the vertical sliding window 1 (opening device) and the locking function of the sway prevention mechanism 5, thus contributing to reducing the number of parts. Also, the arm 51, which is the main component of the sway prevention mechanism 5 of Example 1, is attached at a prominent position near the handle 6 (a member that can move forward and backward) when the door 3 is opened and closed. That is, the main component of the sway prevention mechanism 5 is arranged at a position that the user will inevitably notice. The fact that the handle 6 functions as the locking mechanism of the sway prevention mechanism 5 can be understood by anyone just by looking. The vertical sliding window 1 (opening device) is often installed in accommodation facilities such as hotels. The handle 6 (a member that can move forward and backward), which is a main component of the draft stopper mechanism 5 in the first embodiment, and the arm 51 are provided in a completely exposed state where they can be seen by the user. And since the draft stopper mechanism 5 has a very simple structure, the user is configured to be able to understand the operation of the draft stopper mechanism 5 without reading the instructions. As described above, the vertical sliding window 1 (opening device) in the first embodiment is provided with a user-friendly draft stopper mechanism 5.

[0019] Note that in the first embodiment, the vertical sliding window 1 is taken as an example of the opening device 1, but the present invention can also be applied to any opening device 1 (door) etc. to which a similar draft stopper mechanism 5 can be attached.

[0020] [Embodiment 2] FIG. 5 is an internal view of the vertical sliding window 1 (opening device) in the closed state according to the second embodiment. The difference from the first embodiment is that the handle 6 is not a component of the draft stopper mechanism 5. Instead, the lock piece 7 functions as a member of the draft stopper mechanism 5. The lock piece 7 is attached to the inner surface 442 of the door end frame chamber. Although not shown in FIG. 5, the position where the lock piece 7 is provided is adjacent to the position where the protrusion 441A (a component of the draft stopper mechanism 5) attached to the prospective surface 441 of the door end frame is located.

[0021] FIG. 6 is an explanatory diagram of the draft stopper mechanism 5 in the second embodiment. FIG. 6(A) is a plan view of the lock piece 7 during the opening and closing operation of the door 3. FIG. 6(B) is a cross-sectional view taken along line C-C attached to FIG. 6(A). The right and left directions are shown in FIG. 6(A). The right and left directions in FIGS. 6(B) to 6(D) are the same as those in FIG. 6(A). As shown in FIG. 6(B), the knob 71 is integrated with the protruding piece 73, and by sliding the slide groove 72 in the left-right direction, the protruding piece 73 moves forward and backward freely from the main body of the lock piece 7. For this reason, the lock piece 7 and the protruding piece 73 are components of a member that can move forward and backward of the draft stopper mechanism 5.

[0022] (Lock piece with the door in the fully closed state) When the door 3 shown in Fig. 5 is in the fully closed state, the tilting prevention mechanism 5 that locks (holds) the door 3 at a predetermined angle does not function as a matter of course. In this state, the protruding piece 73 (a member that can move forward and backward) of the lock piece 7 (a member that can move forward and backward) is in the state shown in Figs. 6(A) and 6(B), and most of it is accommodated inside the main body of the lock piece 7 (a member that can move forward and backward).

[0023] (Lock piece when the tilting prevention mechanism is operating) Fig. 6(C) is a plan view of the lock piece 7 when the tilting prevention mechanism 5 is locked. Fig. 6(D) is a cross-sectional view taken along the line D-D attached to Fig. 6(C). When locking the tilting prevention mechanism 5, the user moves the protruding piece 73 (a member that can move forward and backward) by sliding the knob 71 to the right. Then, due to this operation, the protruding piece 73 (a member that can move forward and backward) protrudes to the right from the main body of the lock piece 7 (a member that can move forward and backward). When viewed from the direction of Fig. 6(C), the upper side of the protruding piece 73 becomes the arm contact portion 731.

[0024] Fig. 6(E) is an explanatory diagram of the positions of the arm 51, the protrusion 441A, and the protruding piece 73 in the locked state of the tilting prevention mechanism 5. Fig. 6(F) is an explanatory diagram showing the positional relationship between the lock piece 7 and the arm 51 when the tilting prevention mechanism 5 is locked. The state where the knob 71 of the lock piece 7 (a member that can move forward and backward) is moved and the protruding piece 73 (a member that can move forward and backward) protrudes with respect to the arm 51 is shown. The user moves the protrusion piece 73 (a member capable of moving forward and backward), i.e., the knob 71, to the right to move it to the locking position. The protrusion piece 73 (a member capable of moving forward and backward), which is a component of the awning stop mechanism 5, comes to a position protruding with respect to the arm 51. The protrusion 441A guided by the guide groove 511 has come to a position close to the end of the arm 51. And the arm contact portion 731 on the upper surface of the protrusion piece 73 (a member capable of moving forward and backward) contacts the contact surface 53 of the arm 51. At this time, the protrusion 441A is fitted in the recess 512 at the extreme end of the guide groove 511, and the arm contact portion 731 acts so as to press the protrusion 441A toward the recess 512. By this operation, the protrusion 441A fitted in the recess 512 is restricted so as not to come out of the recess 512. By this series of operations, the awning stop mechanism 5 is in a locked state.

[0025] (Effect of Embodiment 2) In Embodiment 1, the handle 6 also serves as a locking mechanism when the door 3 is closed and a member capable of moving forward and backward of the awning stop mechanism 5. In contrast, the handle 6 of Embodiment 2 does not serve as a component of the awning stop mechanism 5. The component of the awning stop mechanism 5 in Embodiment 2 is the lock piece 7, which has a very simple structure. And the lock piece 7 is arranged near the arm 51, which is the main member of the awning stop mechanism 5, and is attached at a prominent position as shown in FIG. 5. Embodiment 2 is designed so that it can be immediately understood from the gap of the door 3 that when the door 3 is locked (held) at a predetermined angle by the awning stop mechanism 5, the arm 51 cannot be moved by the protrusion piece 73. The member capable of moving forward and backward (protrusion piece 73) of the awning stop mechanism 5 in Embodiment 2 has a structure that only requires sliding the knob 71 of the lock piece 7, and has a simple structure that can be immediately understood even by a user who first contacts the awning stop mechanism 5 of Embodiment 2.

[0026] (Effects of Embodiment 1 and Embodiment 2) Both Embodiment 1 and Embodiment 2 are arranged such that the awning stop mechanism 5 is exposed and visible to the user, and have a simple structure that can be immediately understood. The vertical sliding-out window 1 (opening device) in Example 1 and Example 2 has a much improved usability such that an inexperienced user can operate it immediately, compared with the draft-stopping mechanisms of conventional opening devices. Also, as examples of members that can move forward and backward, Example 1 (handle 6) and Example 2 (lock piece 7) have been described in this specification. This is an exemplification, and any member that can move forward and backward of the draft-stopping mechanism 5 may be used as long as it can be locked to the arm 51.

[0027] As described above, the embodiments according to the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to these embodiments, and design changes and the like within the scope not departing from the gist of the present invention are also included in the present invention.

[0028] Also, as long as there are no particular contradictions or problems in their purposes and configurations, etc., the above-described embodiments can be combined by diverting each other's technologies.
