Description

  The present invention relates to an open / close surface lattice. In particular, the present invention relates to an openable surface lattice used for sliding doors.

  FIG. 6 is a perspective view schematically showing the structure of a conventional sliding door. In general, an opening such as a window or an entrance of a house or an office, for example, as shown in FIG. 6, is a pair of doors D1 arranged so as to open and close the opening surrounded by the frame F by moving horizontally to the frame F. , D2 are attached, that is, a so-called sliding door structure. The doors D1 and D2 are engaged with grooves or upper rails UR and lower rails LR arranged above and below the frame F, respectively. Moreover, the locking tool K1 is provided in the overlap part of the doors D1 and D2, and the doors D1 and D2 are prevented from being opened from the outside. Furthermore, generally, a screen door W is disposed outside the doors D1 and D2.

  By the way, in summer, the doors D1 and D2 may be opened in order to cool or ventilate the room by taking in cool outside air. There is no choice but to close doors D1 and D2.

  For this reason, conventionally, various lattice doors that can be attached to the opening of the frame F have been proposed. For example, Patent Literature 1 proposes a lattice door that is mounted on a rail of a sash door. The device disclosed in this publication has an adapter that can be adapted to various frame edge structures. Further, Patent Document 2 proposes a lattice door whose position can be adjusted in the vertical direction at a mounting portion of the lattice door.

On the other hand, when a face grid is attached, it becomes difficult to escape from the indoors in an emergency, and therefore an openable face grid has also been proposed (for example, Patent Document 3).

  However, in Patent Documents 1 and 2, there is no need to install a support frame around the opening of the building, and it can be easily installed in an apartment house such as a condominium or a rental housing, but it is inconvenient for opening and closing the opening. Met. That is, in order to open and close the lattice doors of Patent Documents 1 and 2, it is necessary to remove one end of the lattice door and attach the lattice door again. Moreover, in patent document 3, although opening and closing of an opening part is easy, mounting | wearing of a surface lattice was inconvenient. That is, in order to attach the surface lattice of Patent Document 3, it is necessary to install a support frame around the opening of the building, which requires work. This has the problem that construction is not permitted and cannot be installed in condominiums and rental housing.

  The present invention has been made to solve the above-described problems, and can be easily attached to a sliding door without requiring construction on a building structure, and can be easily opened and closed. It is an object of the present invention to provide an open / close plane lattice that does not interfere with the opening and closing of the other door or screen door and can prevent entry from the outside.

As a result of intensive studies to achieve the above-mentioned object, the present inventor has come up with a method of mounting an open / close-type surface lattice on an opening of a sliding door using a rail groove or rail of the sliding door.
Here, the “sliding door” is a structure in which a door is fitted into each groove or rail at the edge of an opening such as a doorway or window of a building in which at least two parallel grooves or rails are formed vertically. It is a door that opens and closes an opening when the door is pulled in the horizontal direction.

  However, if the gap between the installed face grid and the sliding door opening is large, it will not be possible to prevent entry into the room. In addition, if the door has a glass surface, the glass surface will be broken if a plane lattice cannot be installed along either door or window of the two sliding doors even when the two sliding doors are closed. It will not be possible to prevent the intrusion into the indoors. In addition to these problems, it will not interfere with the opening and closing of the other door or screen door, it will not interfere with the use of sliding doors, and the installed face grid will be difficult to remove from the outside. There is a need.

  Therefore, the present inventor constructed the plane lattice from the folding door, and paid attention to the rail groove of the sliding door or the mounting structure of the folding door to the rail, and the installed folding door and the opening of the sliding door. The vertical and horizontal gaps between the doors can be adjusted while being limited to a certain limit or less, and it can be difficult to remove from the outside when the folding door is extended in the sliding door. Created a mounting adjustment structure.

Based on these research results, in order to solve the above-mentioned problems, the open / close type surface grating of the present invention is such that the sides of a pair of grating plates are connected via a connecting part, and can be refracted and stretched at the connecting part. Folding door configured in,
A folding lock that prevents refraction of the foldable folding door;
An upper runner and a lower runner attached to the upper and lower ends of both side edges of the folding door so as to maintain a constant sliding direction regardless of the bending and stretching of the folding door;
The upper runner is arranged on the upper runner so that the arrangement position in the vertical direction can be adjusted only from the surface facing the extending direction of the folding door. And a stopper for preventing the openable face lattice from being detached from the saddle of the sliding door by restricting the release of the engagement with the upper runner . (Claim 1). With such a configuration, the open / close surface lattice can be mounted by engaging the upper runner and the lower runner with a groove or a rail formed in the sliding door cage. In addition, the open-and-close surface grid has upper and lower runners that slide along the rails or rail grooves of the opening frame to open and close the folding door, and the folding door is in an extended state by the folding lock, the locking device and the contact member. Sometimes it is substantially fixed to the frame of the opening and the side surface of the sliding door, and in such a state, the side surface of the frame and the sliding door prevents the detachment stopper and the contact member from being removed from the outside. In other words, the open / close face grid of the present invention can be easily attached to the sliding door without requiring construction on the building structure, can be easily opened and closed, and can also be used to open and close the other door or screen door. Intrusion from the outside can be prevented without causing any trouble. Here, the “sliding door” means that a door is fitted in each groove or rail at the entrance of a building or a window of a window in which at least two parallel grooves or rails are formed on the upper and lower sides. The door is configured to open and close the opening when the door is pulled in the horizontal direction.

Further, each of the upper runner and the lower runner has an abutting member arranged so that the protruding length in the horizontal direction can be adjusted, and the abutting member is arranged only from a surface facing the extending direction of the folding door. The installation position can be adjusted, and at least one of the upper runner and the lower runner is configured such that an upward or downward protruding length can be adjusted from an upper end or a lower end of both side edges of the folding door. (Claim 2). If comprised in this way, since the opening-and-closing surface lattice can be mounted | worn according to the magnitude | size of the opening part of a sliding door, the versatility of an opening-and-closing surface lattice can be improved.

  Further, from the viewpoint of more reliably obtaining the effects of the present invention, the upper runner and the lower runner each have a shaft in which a spiral is engraved, and each of the shafts is screwed into a sleeve having a spiral hole. When the bolts mounted on the corresponding contact members are screwed into the bolt holes of the upper runner and the lower runner, the contact members are rotatably mounted in the holes at the upper and lower ends of both side edges of the folding door. (Claim 3)

The abutting member may be disposed so as to cover the disengagement stop disposed. If comprised in this way, since the come-off stopper is covered with an abutting member, the removal from the outside of the come-out stopper is more reliably prevented by the side surfaces of the frame and the sliding door.

  Since the openable face lattice of the present invention can be easily attached to the sliding door without requiring construction on the building structure, it is difficult to attach the conventional face lattice like windows and doors of apartment houses and rental housing. It can be easily attached to windows and doors. In addition, since the open / close type surface lattice of the present invention can be easily opened and closed, it can be easily attached to a window or a door that has been difficult to attach to a conventional surface lattice, such as a sweep-out window through which a person passes. Furthermore, since the open / close face grid of the present invention does not interfere with the opening / closing of the other door or the screen door, it does not interfere with the use of the sliding door. And since the opening-and-closing surface lattice of the present invention is prevented from being removed from a window or a door in the extended state, entry from the outside can be prevented. In other words, it has the effect of improving the crime prevention property of a house or office widely.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

(Embodiment 1)
First, the open / close type surface lattice of the present embodiment will be described.

  FIG. 1 is a perspective view schematically showing an example of an openable surface lattice according to the first embodiment of the present invention.

  In FIG. 1, the openable face lattice 100 of the present embodiment is installed in an opening formed between the side face DA of the door D1 and the frame F in the closed position. The position of the other door D2 may be anywhere.

  The open / close type surface lattice 100 has a folding door 2 configured such that the sides of the pair of lattice plates 1 are connected to bend freely. Here, a pair of lattice plates 1 are connected by a hinge 2A mounted on the side surface 1A. As a result, when the folding door 2 is extended, the attachment surface of the hinge 2A, that is, the side surface 1A is joined, and the attachment portion of the hinge 2A cannot be contacted from the outside. Can do.

  The folding door 2 is provided with a folding lock 3 that is fixed and locked in a state in which the folding door 2 is extended, and an upper runner 10 and a lower runner 20.

  As the folding lock 3, a general locking tool can be used. Here, the lock piece (not shown) is advanced and retracted into the hole 3A formed in the side surface 1A of the lattice plate 1 by inserting and turning the key K2 into the locking lock 3 when the folding door 2 is extended. By doing so, the folding of the folding door 2 can be prevented and released. The folding lock 3 may be constituted by a dial-type key.

  The upper runner 10 and the lower runner 20 have a shaft 11 engraved with a spiral, and the sleeve 7 is engraved with a spiral on the inner periphery. Then, the shaft 11 is screwed into the sleeve 7, and the sleeve 7 is fitted into the holes 4, 5 at the upper end surfaces of both side edges of the folding door 2 so as to be rotatable. As a result, when the folding door 2 is bent and stretched, the sleeve 7 rotates relative to the folding door 2 and the upper runner 10 and the lower runner 20 slide on the upper rail UR and the lower rail LR, respectively. That is, the upper runner 10 and the lower runner 20 are attached to the upper and lower ends of both side edges of the folding door 2 so as to maintain a constant sliding direction regardless of the bending and stretching of the folding door 2.

  Further, when the upper runner 10 and the lower runner 20 are rotated while holding the sleeve 7, the shaft 11 moves forward and backward in the sleeve 7. And the protrusion length of the up-down direction from the folding door 2 of the upper runner 10 and the lower runner 20 is adjusted by fitting the sleeve 7 in the holes 4 and 5. Thereby, the folding door 2 can be attached to the frame F in accordance with the height of the opening of the frame F.

  The sleeve 7 may be fixed to the holes 4 and 5 so that the shaft 11 slides on the spiral portion of the sleeve 7 by bending and stretching the folding door 2. That is, the shaft 11 moves up and down by sliding, but there is no problem as long as the folding / extending distance of the folding door 2 is such a distance that the open / close plane lattice 100 cannot be removed from the frame F by the advancement and retraction of the shaft 11. .

  Furthermore, the shaft 11 is at most 15 cm. As a result, the length of the protrusion in the vertical direction from the upper rail UR and the lower rail LR and the folding door 2 can be up to 15 cm at the longest. In other words, it can be limited to less than the interval that adults can pass. Therefore, the opening portion of the sliding door D1 to which the open / close type surface lattice 100 is attached is limited to the vertical width equal to or greater than the vertical width of the folding door 2 and less than the vertical width of the folding door 2 +30 cm.

  FIG. 2 is a three-side view of the upper runner of FIG. As shown in FIG. 2, the upper runner 10 includes a main body 12, a shaft 11 fixed to the main body 12 by welding or the like so as to extend in a vertical direction from the lower surface of the main body 12, and a contact provided on a side surface of the main body 12. The contact member 13 and the stopper 15 are provided.

  The main body 12 has a groove 12 </ b> A with which the upper rail UR is engaged on the upper surface. A resin U-groove member 12 </ b> C is fitted in the groove 12 </ b> A of the main body 12. As a result, the contact surface of the upper runner 10 with the upper rail UR can be smoothed, so that the sliding performance of the upper runner 10 can be improved and scars on the upper rail UR can be prevented.

  The main body 12 and the contact member 13 are structured such that the contact member 13 can enter the main body 12. Here, a bolt 14 is inserted into a hole 13 </ b> D formed on a side surface 13 </ b> B of the contact member 13, that is, a surface facing the extending direction of the folding door 2. The bolt 14 is prevented from moving in the axial direction behind the side surface 13B by the retaining ring 14A. And the front-end | tip of the volt | bolt 14 is penetrated by the volt | bolt hole formed in the side surface 12B of the main body 12. FIG. As a result, the bolts 14 are arranged facing the extending direction of the folding door 2, so that when the folding door 2 is in the extended state, the frame surface of the opening of the sliding door, i.e., the frame, can be twisted. F and the side DA of the door D1 are obstructive. That is, it is possible to prevent the contact member 13 from being removed from the outside.

  Here, a plate 13 </ b> C is attached to the side surface 13 </ b> B of the contact member 13 so as to surround the bolt head of the bolt 14. As a result, the bolt head does not protrude from the side surface of the contact member 13, and the plate 13C of the contact member 13 is in the extended state of the folding door 2, and the frame surface of the sliding door opening, that is, the frame F and the door D1. Therefore, it is possible to prevent the bolt 14 from being twisted from the outside when the folding door 2 is in the extended state. The plate 13C is made of an elastic material such as resin or rubber. Thereby, it can contact | abut without leaving a scar on the frame surface of the opening part of a sliding door, ie, the frame F, and the side surface DA of the door D1.

  The abutting member 13 is attached to the main body 12 such that the protruding length in the horizontal direction with respect to the main body 12 can be adjusted by turning the bolt 14. Here, the horizontal width of the contact member 13 and the helical length of the bolt 14 are less than 15 cm. As a result, the horizontal projection length of the frame surface of the opening of the sliding door, that is, the side surface DA of the frame F or the door D1 and the folding door 2, can be up to 15 cm at the longest. In other words, it can be limited to less than the interval that humans can pass. Therefore, the opening of the sliding door D1 to which the open / close-type surface lattice 100 is attached is limited in the left-right width to be equal to or greater than the left-right width of the folding door 2 and less than the left-right width of the folding door 2 +30 cm.

  The stopper 15 is disposed in the main body 12 by a spiral 16 that is passed through a vertically long bolt hole formed in the side surface 12 </ b> B of the main body 12. Thus, after the folding door 2 is installed in the opening, the release stopper 15 is disposed on the spiral 16 in the vicinity of the upper rail UR, thereby restricting the release of the upper runner 10 from the upper rail UR. As a result, it is possible to make it difficult to remove the opening-and-closing surface lattice 100 from the opening.

  Here, since the side surface 12 </ b> B is a surface facing the extending direction of the folding door 2, the spiral 16 is disposed facing the extending direction of the folding door 2. Thus, when the folding door 2 is in the extended state, the frame surface of the opening of the sliding door, that is, the side surface DA of the frame F and the door D1 is an obstacle to twisting the spiral 16. That is, it is possible to prevent the removal stopper 15 from being removed from the outside.

  The spiral head of the spiral 16 is covered with the side surface 13B of the contact member 13. Thus, in order to remove the face lattice 100 from the sliding door, the bolts 14 must be removed and the contact member 13 must be removed so that the spiral 16 can not be accessed. Therefore, the function of preventing the intrusion of the openable lattice 100 is further improved.

  FIG. 3 is a three-side view of the lower runner of FIG. As shown in FIG. 3, the lower runner 20 has the same structure as the upper runner 10, and the stopper member 15, the spiral 16 and the U-groove member 12 </ b> D are removed, and the roller member 26 having the roller 25 is attached to the main body 12. It differs in that it is attached. Therefore, since it is the same as that of the upper runner 10 except this, only a different point is demonstrated. Also, in FIG. 3, the same or corresponding parts as in FIG.

  In FIG. 3, a roller 24 is attached to the groove 12A of the main body 12 so as to slide on the lower rail LR engaged with the groove 12A. The roller 24 can be mounted in various ways. Here, the roller member 25 attached to the U-groove portion of the U-groove holding member so that the roller 24 rotates in the U-groove direction is used as the main body 12. It is attached to the groove portion 12A. The roller member 25 is attached such that the rotation direction of the roller 24 coincides with the extending direction of the groove 12A. Accordingly, the lower runner 20 can slide on the lower rail LR.

  Next, a procedure for attaching the openable surface lattice 100 will be described.

  First, the folding door 2 is bent, and the lengths of the upper runner 10 and the lower runner 20 of the open / close face grid 100 are engaged with the upper rail UR and the lower rail LR of the sliding door. The shaft 11 is screwed into the holes 4 and 5 while adjusting.

  Next, the stopper 15 is disposed close to the upper rail 15, and the stopper 15 of the upper runner 10 is disposed by the spiral 16. This makes it difficult to disengage the groove portion 12A of the upper runner 10 and the upper rail UR and release the engagement of the groove portion 12A of the lower runner 20 and the lower rail LR.

  Then, in all the upper runner 10 and the lower runner 20, the contact member 13 is fitted into the main body 12 while the bolt 14 is screwed into the main body 12.

  And the folding door 2 is extended | stretched and it adjusts so that the contact member 13 contact | abuts to the frame surface of the opening part of a sliding door, ie, the frame F, and the side surface DA of the door D1. As a result, the openable surface lattice 100 is attached to the sliding door. The open / close-type surface lattice 100 can be easily opened and closed by placing the hand on the lattice of the folding door 2 or the bar of the refracting part from the inside of the building and pulling it forward. In addition, by locking the folding lock 3, refraction of the open / close surface lattice 100 is prevented, and entry into the building from the opening of the sliding door can be prevented. Also, as shown in FIG. 4, the openable surface grid 100 does not interfere with the opening and closing of the other door D2 and the screen door W. Therefore, the other door D2 and screen door regardless of the open / closed state of the openable surface lattice 100. W can be placed in the opening of the sliding door.

  Here, FIG. 4 is a top view showing a mounting pattern of the openable surface lattice of FIG. 1 mounted on the sliding door.

  As shown in FIG. 4 (a), the open / close surface lattice 100 is mounted on the frame surface of the sliding door opening, that is, the frame F and the side surface DA of the door D1, as shown in FIG. 4 (b). If necessary, it can be opened and closed and can pass through the opening, or it can deliver goods.

  Moreover, as shown in FIG.4 (c), in the state which closed a pair of sliding doors, the opening-and-closing type surface grating | lattice 100 can be each mounted | worn with the rail of both doors D1 and D2 of a sliding door. As a result, the sliding door is covered by the open / close-type surface lattice 100, and both the doors D1 and D2 can be improved in crime prevention during absence or sleeping.

  As described above, the upper runner 10 and the lower runner 20 can slide on the upper and lower rails or rail grooves of the frame F of the opening, here the upper rail UR and the lower rail LR, by the configuration of the openable face grid 100 of the present invention. The engagement stopper 15 is disposed so as to limit the release of the engagement by the spiral 16 after the engagement, and the contact member 13 is folded by the bolt 14 and the frame surface of the opening portion when the door 2 is extended. That is, it is disposed so as to contact the frame F and the side surface DA of the door D1, and the folding door 2 faces the frame surface of the opening of the sliding door, that is, the side surface DA of the frame F and the door D1 when extended. The bolt 14 of the contact member 13 is disposed in the surface 13B of the contact member 13 to be engaged, and the spiral 16 of the stopper 15 is disposed in the side surface 12B of the main body 12 covered with the contact member 13. Yes. As a result, the open / close face grid 100 of the present invention can be easily attached to the sliding door without requiring construction on the building structure, and can be easily opened / closed, and the other door or screen door can be opened / closed. Intrusion from the outside can be prevented. Therefore, it can be easily attached to the windows and doors of apartment houses and rental houses where it has been difficult to attach the face grids in the past, and it is generally wide and the crime prevention property of the house can be improved.

Further, the abutting member 13 is arranged so that the protruding length in the horizontal direction can be adjusted, and in the extended state of the folding door 2, the surface facing the frame F of the opening and the side surface DA of the door D 1, that is, the folding door. The arrangement position can be adjusted only from the surface facing the extending direction 2, and at least one of the upper runner 10 and the lower runner 20 is configured such that an upward or downward protruding length can protrude. Therefore, the open / close surface grating 100 can be mounted in accordance with the size of the opening of the sliding door, so that the versatility of the open / close surface grating 100 can be improved.
(Embodiment 2)
The second embodiment is an embodiment in which the structure of the upper runner 10, the lower runner 20 and the sleeve 7 of the first embodiment is simplified. Therefore, since the configuration other than these is the same as that of the first embodiment, only the differences will be described.

  FIG. 5 is a perspective view schematically showing an example of the openable surface lattice according to the second embodiment of the present invention.

  In the open / close face grid 200 of the present embodiment, the upper runner 210 and the lower runner 220 have a shaft 211, and the shaft 211 is fitted to the sleeve 207.

  The sleeve 207 is fitted into the holes 4 and 5 on the upper end surface of both side edges of the folding door 2. A convex portion around the inner surface of the sleeve 207 and a concave portion around the shaft 211 are rotatably fitted. Therefore, the upper runner 10 and the lower runner 220 can slide on the upper rail UR and the lower rail LR while the shaft 211 and the sleeve 207 rotate according to the bending and stretching of the folding door 2.

  The upper runner 210 and the lower runner 220 are the main body 12, the shaft 11 fixed to the main body 12 by welding or the like so as to extend in the vertical direction from the lower surface of the main body 12, and the contact disposed on the side surface of the main body 12. A member 13 and a detent 15 are provided.

  Although the upper runner 210 and the lower runner main body 212 are not shown in the drawing, as in the first embodiment, the upper rail UR or the lower rail LR is formed with grooves on the upper surface or the lower surface, and the resin U A groove member is fitted. However, the upper runner 210 and the main body 212 of the lower runner do not have the contact member 13, and the end surface of the main body 212 is folded and the frame surface of the opening, that is, the side surface DA of the frame F and the door D <b> 1 in the extended state of the door 2. It is comprised so that it may contact | abut.

  Next, attachment of the open / close type surface lattice 200 is such that the groove portion 12A of the upper runner 210 and the lower runner 220 is engaged with the upper rail UR and the lower rail LR of the sliding door while the open / close type surface lattice 200 is stretched or bent. By combining them. Adjustment work as in the first embodiment is not necessary.

  As described above, in the standard sliding door, the openable surface lattice 200 of the present embodiment is suitable, and the structure can be simplified as compared with the first embodiment.

  Although the embodiment of the present invention has been described in detail, the present invention is not limited to the above embodiment. For example, the structure of the upper runner and the lower runner and their mounting structure can be replaced by other general structures. Moreover, in Embodiment 1, the volt | bolt 14 may be comprised so that a volt | bolt head may be accommodated in the recessed part provided in 13 C of side surfaces. Accordingly, the plate 13 can be made of a thin cloth material, rubber material, or the like, or can be made unnecessary.

  Since the openable face lattice of the present invention can be easily attached to the sliding door without requiring construction on the building structure, it is difficult to attach the conventional face lattice like windows and doors of apartment houses and rental housing. It can be easily attached to windows and doors. In addition, since the open / close face grid of the present invention can be easily opened and closed, it can be easily mounted on windows and doors that have conventionally been difficult to mount on a plane grid, such as a sweep-out window through which a person passes. Furthermore, since the open / close face grid of the present invention does not interfere with the opening / closing of the other door or the screen door, it does not interfere with the use of the sliding door. And since the opening-and-closing surface lattice of the present invention is prevented from being removed from a window or a door in the extended state, entry from the outside can be prevented. That is, the open / close type surface grating of the present invention is useful as an open / close type surface grating that improves the crime prevention property of a house or office in a wide range.
