  In Patent Documents 1, 2, and 4, a substantially concave frame (frame) in which the lower ends of the left and right side frames (vertical members) are connected by a lower frame is stretched and held between opposing walls. The door frame is pivotally supported so that it can be opened and closed back and forth. That is, the door body is pivotally supported by an axis perpendicular to one side frame and can be locked to the other side frame.

  In Patent Document 3, a frame in which left and right columns (vertical members) and a lower frame are combined in a concave shape is stretched and held between left and right walls, and left and right doors are respectively separated by vertical support shafts. It is shown that it is pivotably held on a column. Patent Document 4 also shows that, similarly to Patent Document 3, the door is divided into left and right parts and pivotally supported on both left and right columns.

  In Patent Document 5, a mounting member is fixed to each facing wall (or a building frame such as a pillar), and one side edge of the door is rotatable about a vertical support shaft on the mounting member fixed to one wall. It is shown that it is held and can be locked to a mounting member that fixes the other side edge of the door to the other wall. Here, a caster wheel is provided in the lower part near the rotation end of the door, and the door is rotated in the front-rear direction while rolling the caster wheel on the floor surface.

  As described above, in Patent Documents 1 to 4, the frame (frame) is concave, and the side frames on both sides are fixed to the wall by projecting from the inside. In this way, one or two doors are pivotally supported on the frame fixed to the wall so as to be pivotable back and forth.

  However, in this case, the frame (frame) is pressed against the wall (fixed) and fixed, so that when the door is opened, the frame becomes unstable and the frame moves or tilts. easy. That is, when the door is closed, the side frame can be strongly pressed (protruded) against the wall while supporting the door, but when the door is opened, the side frame is supported only at the lower end. In Patent Document 5, such a problem does not occur because the mounting member is fixed to the wall with a wood screw or an adhesive. However, in this case, the wall is damaged or soiled. There was a problem that it could not be used or fixed firmly. Further, when changing the mounting position, the mounting member must be detached from the wall, which is inconvenient.

  The present invention has been made in view of such circumstances, and while the frame is stretched and fixed to the wall, the frame can be always firmly held on the wall, and the wall may be damaged. It is another object of the present invention to provide an infant safety fence that does not cause a problem that it cannot be used depending on the wall material and can be easily changed in installation position.

This object according to the invention is installed between the pair of walls face each other across the passage, a infant safety fence for limiting the infant passage, and abut against the wall at upper and lower ends A pair of left and right vertical members that have upper and lower projecting parts to be fixed and the middle part of these upper and lower projecting parts are separated from the wall , and are compressed between the lower projecting parts of these both vertical members, a lower brace member for pressing them under突張Ri portions to the left and right of the wall with the restoring force of elongation direction, the two longitudinal members compressively to the upper of the two longitudinal members have a stretch direction of the restoring force at both ends between the the upper brace member always slidable underneath on one press membrane against the wall in the middle portion of the lower突張Ri unit-lock the two longitudinal members at the upper limit position of at least the sliding range of the upper strut member Locking means, the vertical members, the lower tension member, and the upper tension member Tension passed infant safety fence, characterized by comprising a protective member capable of expanding and contracting in the vertical direction within the sliding range of at least the upper brace member between is accomplished by.

That is, while the upper and lower ends of the pair of left and right vertical members are in contact with the wall, a rectangular frame is formed by the vertical members and a pair of upper and lower tension members having a restoring force in the extending direction, and the upper tension member is The member can be slid up and down. When the guardian passes, the upper strut member is lowered so as to straddle it.

Since the upper and lower ends of the left and right vertical members are always pressed against the wall by upper and lower projecting members having a restoring force in the extending direction , the rectangular frame is firmly fixed to the wall. Here, the upper tension member can slide up and down with respect to the vertical member, and the protection member stretched over the frame can be expanded and contracted in the vertical direction within the upper and lower sliding range of the upper tension member. When restricting, the upper strut member can be locked at a high position.

  Further, when the guardian goes in and out, the lock can be released and the upper tension member can be slid downward. At this time, since the upper strut member always pushes the vertical member toward the wall, the pressing force against the wall of the vertical member does not decrease excessively, and the frame body may become unstable and move or tilt. There is no. Furthermore, there is no need to use wood screws or adhesive on the wall, so there is no risk of damaging or soiling the wall, and it is easy to change the installation location.

This infant safety fence can be installed between walls such as corridors, door frames, and pillars. Thus the wall in the present invention Ru broad concept der, including door frames and pillars. Since or intermediate portion is away from the wall, the left and right end portions of the intermediate portion on the brace member assembly of the (sliding member) in the vertical direction into the through is thereby it is possible to frame is good.

A case in which the vertical member engages (penetrates) so as to be slidable up and down is fixed to both ends of the upper tension member, and a roller that rolls into the vertical member from the inside (from the passage side toward the wall) in this case, preferably May hold a pair of upper and lower rollers. Roller is because it is possible to convey突張Ri force Ue突tension member while allowing vertical sliding on the brace member relative to the longitudinal member to the longitudinal members smoothly (claim 2).

If the lock means is provided with a lever extending below the upper tension member, the lever is not likely to be inadvertently operated even when an infant hangs his hand on the upper tension member from above. If the lever is provided with an engaging claw that engages with the vertical member at a predetermined position of the upper tension member, for example, a position where the upper tension member is pulled up, the upper tension member does not fall inadvertently. 3 ).

It is preferable that the upper and lower strut members have a habit of returning to the stretch direction, that is, the extension direction, and the length can be adjusted in accordance with the interval between the walls to be attached. In order to make the length adjustable, the protective member needs to be extendable in the width direction as well as the vertical direction. Such protective member may for example assume that you have created a cloth or net, good ones to detachably attach the four sides such as in wound over and fastener to the frame (claim 5).

The upper and lower strut members include an inner pipe and an outer pipe that are slidable relative to each other in a longitudinal direction, and a long coil spring that is built in the inner and outer pipes. A structure in which the diametrical transverse pin fixed to one of the inner and outer pipes and the other of the inner and outer pipes is engaged with another position of the coil spring can be employed. In this case, the position where the transverse pin engages with the coil spring is changed by relatively rotating the inner and outer pipes, and the length of the tension member and the restoring force in the length direction (that is, the tension force) can be adjusted. (Claim 4 ).

  FIG. 1 is a perspective view of the embodiment of the present invention as seen from the front side, FIG. 2 is a front view showing the frame body from the back side, excluding the protective member, and FIG. 3 is a front cross section showing the internal structure. 4 is a perspective view similarly seen from the front side, FIG. 5 is a perspective view showing the internal structure with a part broken away, and FIG. 6 is an enlarged sectional view of the vicinity of one end of the upper tension member seen from the back side. 7 is a perspective view, and FIG. 8 is a perspective view showing a state in which the upper tension member is lowered from the front side.

  In these drawings, reference numeral 10 denotes a frame. The frame 10 has a pair of left and right vertical members 12, 14, a lower projecting member 16, and an upper projecting member 18. The vertical members 12 and 14 have inner pipes 12a and 14a and outer pipes 12b and 14b, respectively, which are slidably combined with each other in the length direction. The inner pipes 12a and 14a and the outer pipes 12b and 14b are locked with pins 20 and 20 in a stretched state.

  That is, as shown in FIGS. 2 and 3, the pins 20 and 20 are located above the inner pipes 12a and 14a with the inner pipes 12a and 14a facing down, and the U-shaped leaf springs 20a and 20a are connected to the inner pipe 12a. , 14a are urged outward through the radial direction. These pins 20 and 20 are engaged with engaging holes provided in the outer pipes 12b and 14b with the outer pipes 12b and 14b extended, and the inner pipes 12a and 14a and the outer pipes 12b and 14b are locked to each other. If the pins 20 and 20 are pushed from the outside toward the center of the inner pipes 12a and 14a and the outer pipes 12b and 14b, the pins 20 and 20 are unlocked, and the longitudinal members 12 and 14 can be shortened.

  The lower ends of the vertical members 12 and 14 are connected by a lower tension member 16, and an outward restoring force (stretching force) is applied between these lower ends. That is, substantially inverted T-shaped connecting members 22 and 24 can be attached to and detached from the lower ends of the vertical members 12 and 14, that is, the lower ends of the inner pipes 12 a and 14 a by the same structure as the pins 20 and 20 of the vertical members 12 and 14. The lower projecting member 16 is connected between the connecting members 22 and 24.

  The lower strut member 16 includes an inner pipe 16a, an outer pipe 16b, and a long coil spring 16c loaded inside the lower pipe 16a, which are slidable and rotatable in the lengthwise direction (that is, telescopically). . The inner pipe 16 a is fixed to one connecting member 22 and is perpendicular to the vertical member 12. The outer pipe 16 b is rotatably held by the other connecting member 24 and is perpendicular to the vertical member 14.

  That is, a cylindrical handle 24a into which the outer pipe 16b is inserted is rotatably held by the connecting member 24, and the outer pipe 16b is fixed to the handle 24a so that both can rotate integrally. One end of the long coil spring 16c is fixed to the outer pipe 16b inside the handle 24a. That is, one end of the coil spring 16c is bent at a right angle in the shape of a ring, and the tip of the coil spring 16c is pressed against the stopper pin 16d. Yes.

  The other end of the coil spring 16c extends into the inner pipe 16a and engages with a transverse pin 16f penetrating radially in the vicinity of the entry end of the inner pipe 16a into the outer pipe 16b. Therefore, when the handle 24a is rotated, the outer pipe 16b and the coil spring 16e rotate integrally. The position of engagement with the transverse pin 16f is changed by the rotation of the coil spring 16c. As a result, the length of the lower strut member 16 and the restoring force (stretch force) in the length direction can be adjusted.

  The connecting members 22 and 24 are integrally formed with lower projecting portions 26 and 28 that protrude outward in the extending direction of the lower projecting member 16. End members 30 and 30 are fixed to the upper ends of the vertical members 12 and 14. These end members 30, 30 are integrally formed with upper projecting portions 32, 32 protruding in the same direction as the projecting portions 26, 28 of the connecting members 22, 24.

  The upper projecting portions 32 and 32 and the lower projecting portions 26 and 28 press the walls 34 and 34 when the frame body 10 is mounted between the walls 34 and 34 (see FIG. 2). 10 is fixed to the wall 34, and a rubber having a large friction coefficient is fitted into a surface that contacts the wall 34. Here, since the upper projecting portions 32 and 32 and the lower projecting portions 26 and 28 protrude toward the wall 34, the intermediate portions of the vertical members 12 and 14 are separated from the wall 34 when fixed to the wall 34.

  The upper strut member 18 is connected to slide members 36 and 38 that can slide up and down with respect to the outer pipes 12 b and 14 b of the vertical members 12 and 14. The slide members 36 and 38 have left and right cases 40 and 42, and the vertical members 12 and 14 penetrate the cases 40 and 42 so as to be vertically movable.

  The upper strut member 18 has substantially the same structure as the lower strut member 16. That is, while the inner pipe 18a is fixed to the slide member 36, the outer pipe 18b is fixed to the handle 38a rotatably held by the slide member 38, and the coil spring 18c is connected to the outer pipe with the stopper pin 18d and the retaining pin 18e. Fixed with. Then, by rotating the handle 38a integrally with the outer pipe 18b and the coil spring 18c, the engagement position between the coil spring 18c and the transverse pin 18f can be changed.

In the cases 40, 42 of the slide members 36, 38, there are a pair of upper and lower rollers 44, 44, 46, 46 that roll outwardly (toward the wall 34) with respect to the outer pipes 12b, 14b of the vertical members 12, 14. It is installed. Since the upper brace member 18 has a restoring force in the expanding direction by the coil spring 18c, rollers 44,44,46,46 outer pipe 12b by the restoring force of the coil spring 18c, while always pressing 14b to the wall 34 facing By rotating the rollers 44, 44, 46, 46, the slide members 36, 38 can smoothly slide up and down.

  The slide members 36 and 38 are provided with locking means formed by a lever 48 or the like. FIG. 6 shows only one slide member 36, but the other slide member 38 has the same structure, so only the slide member 36 will be described.

  The lever 48 is pivotally supported by a support shaft 50 (integrated with the lever 48, FIG. 7) located between the rollers 44, 44 in the case 40, and extends downward from the upper tension member 18. To do. The lever 48 is given a downward return behavior by a return spring 52. The lever 48 is provided with an engaging claw 48a that protrudes from the vicinity of the lower portion of the support shaft 50 toward the outer pipe 12b. The engagement claw 48a engages with the engagement hole 48b formed in the outer pipe 12b at the position where the upper projecting member 18 is raised (the use position in FIG. 1), and locks the slide member 36.

  Accordingly, if the palms are placed on the left and right ends of the upper projecting member 18 from above and the fingers of the hands are hooked on the levers 48 of the left and right slide members 36 and 38 and simultaneously lifted, the engaging claws 48a will escape from the engaging holes 48b. To do. In this state, the slide members 36 and 38 can be lowered together with the upper tension member 18.

  The protection member 54 is attached to the frame 10 configured as described above. The protective member 54 is made of a flexible material such as cloth or a net. The vertical dimension of the protective member 54 is such that the vertical members 12 and 14 are extended to the maximum and can be wound around the upper and lower projecting members 18 and 16 and fixed by the surface fastener 56 (see FIG. 1). The left and right dimensions are such that the upper and lower projecting members 18 and 16 are stretched and wound around the vertical members 12 and 14 in a state adapted to the widths of the walls 34 and 34, and can be fixed with surface fasteners.

  Note that the lever 48 of the locking means is also wound around the upper portion of the protective member 54 when the upper member 18 is wound around the upper tension member 18 (see FIG. 1). Therefore, the infant is prevented from tampering with and touching the lever 48.

  The safety fence adjusts the lengths of the upper and lower projecting members 16 and 18 in accordance with the distance between the walls 34 and 34. The frame 10 is firmly held on the walls 34 and 34 by pressing the projecting portions 26, 28, 32 and 32 of the frame 10 against the walls 34 and 34 by the restoring force of the coil springs 16c and 18c. If the levers 48 are pulled upward, the upper tension member 18 can be moved up and down. When the safety fence is used, the upper strut member 18 is raised and locked in the position shown in FIGS. In this state, infant traffic is restricted.

  When the guardian passes, the levers 48, 48 are lifted to release the lock, and the upper strut member 18 is lowered (FIG. 8). At this time, since the protective member 54 is flexible, it is folded into a bellows shape. And it can pass easily straddling the lower upper strut member 18. If the upper strut member 18 is lifted and locked in the raised position after passing, the passage of the infant can be restricted again.
