Description

  The present invention relates to a window opening / closing stopper that can be added to an existing opening degree holding mechanism that is installed in a vertical axis rotation window or an opening window and can arbitrarily set the opening angle of the window.

  The vertical axis rotation window and the opening window are provided with an opening degree holding mechanism in order to keep the opening angle constant. The opening holding mechanism is fixed to a lower side surface of the window by a pair of fixing members, a rail having one or more holes on the lower surface, a slider slidably fitted to the rail, and one end of the slider In addition, the other end is constituted by an arm that is pivotally fixed to the upper surface of the window frame. Further, the slider is provided with a convex portion urged in a direction to engage with the hole by a spring, and is engaged and fixed at a hole position provided on the lower surface. The convex portion can be disengaged by a spring actuated by a push button provided on the slider.

  When the window provided with the opening holding mechanism is opened, the slider is pulled by the arm and moves on the rail. When the protrusion provided on the slider engages with the hole provided on the rail, the slider is locked on the rail, and the opening angle of the window is fixed. When the push button is pressed here, the engagement between the convex portion and the hole is released, and the opening / closing operation of the window becomes possible again.

  In the above opening degree holding mechanism, the opening angle of the window can be set only to an angle corresponding to the position of the hole provided in advance in the slider, and the opening angle cannot be arbitrarily set. Therefore, if a general-purpose clamping means such as a scissor vise is attached to an arbitrary position on the rail and used as a stopper for the slider, the movable range of the slider on the rail is limited, and the opening angle of the window falls down for infants, etc. It is possible to make it below the value that prevents However, it is necessary to tighten the rail with a particularly large force in order to securely fix the movement of the slider in order to prevent a fall accident or the like. In such a case, the rail may be deformed and may prevent the slider from sliding. .

  The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a window opening / closing stopper that can securely fix the movement of the slider without pressing the rail with a particularly large force during installation. It is.

  In order to solve the above-mentioned problems, a window opening / closing stopper according to the present invention is provided on a body having a U-shaped longitudinal section having an upper leg portion, a lower leg portion, and a connecting portion for connecting them, and the upper leg portion. A window opening / closing stopper comprising: a substantially planar pressing member that is slidably disposed facing the lower leg portion; and a pressing means that presses the pressing member. The lower leg is provided with a protrusion protruding toward the upper leg.

  According to such an invention, when the pressed member (rail) is pressed and clamped by the pressing member and the protrusion, the protrusion is pierced into the pressed member (rail), so that it is particularly large with respect to the pressed member (rail). The pressed member (rail) can be securely held without applying a pressing force. Since the pressing member is slidably disposed, the pressing member does not come into contact with the pressed member (rail) and is formed in a substantially flat shape, so that a pressing mark hardly remains on the pressed member. Moreover, since the main body is formed in a U-shaped longitudinal section, it can be easily attached to and detached from the pressed member (rail) from the side.

  Moreover, it is preferable that the said pressing member urging means is comprised with the urging member screwed together by the said upper leg part. According to such an invention, a sufficient pressing force can be generated on the pressing member with a simple configuration.

  Preferably, the biasing member includes a recess having a substantially polygonal opening, the recess has a protrusion at the center of the bottom surface, and an upper end of the protrusion is in the vicinity of the opening of the recess. Be placed.

  According to this invention, even if it is intended to rotate the urging member by engaging a fastener having an engaging portion having the same polygonal shape as the opening with the opening, the protrusion in the vicinity of the opening surface of the recess Since the engagement is prevented by this, it is possible to prevent the pressing and holding state of the pressed member (rail) by the biasing member from being inadvertently released.

  Further, a substantially hexagonal opening can be used as the opening of the recess.

  As described above, according to the window opening and closing stopper according to the present invention, when the pressed member is pressed and clamped, the protrusion provided on the lower leg portion pierces the pressed member, and the above-described without applying a large pressing force. Since the member to be pressed can be reliably held, it is possible to prevent a fall accident of an infant or the like. Further, since the pressing member is slidably disposed, the pressing member does not come into contact with the pressed member, and the pressing member is hardly left on the pressed member because it is formed in a substantially flat shape. Furthermore, since the main body of the window opening / closing stopper is formed in a U-shaped cross section, it can be easily attached to and detached from the pressed member.

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

It is a top view at the time. As shown in FIG. 2, the window opening / closing stopper S according to the present embodiment includes a main body 1, a pressing means 2, and a protrusion 3. The main body 1 includes an upper leg portion 4 having a short columnar shape, a lower leg portion 5 having a short columnar shape, and a connecting portion 6 having a cross-sectional shape of an arc shape. The pressing means 2 includes a pressing member 7 and a biasing member 8 as a pressing member biasing means. Further, the window opening / closing stopper S includes a cover 9 and a machine screw 10 that cover the upper and side surfaces of the upper leg 4 of the main body 1 and the outer surface of the connecting portion 6. Two engaging projections 11 are provided. A projection 3 is provided at one end of the machine screw 10 integrally with the machine screw 10, and the projection 3 is formed in a conical shape with a sharp tip.

  Further, a biasing member mounting hole 12 is provided in the upper leg portion 4 of the main body 1, and an internal thread is formed on the inner surface thereof. A through hole 13 is provided in the lower leg portion 5, and an internal thread is formed on the inner surface thereof. A small screw 10 is attached to the female screw so that the protrusion 3 provided integrally with the female screw protrudes from the surface of the lower leg 5 facing the upper leg 4. Further, a groove 14 is provided in the circumferential direction of the lower leg portion 5 in the vicinity of the connecting portion 6 on the outer peripheral portion of the lower leg portion 5, and an engagement protrusion 11 provided on the cover 9 is engaged.

  The urging member 8 is a member formed in a short columnar shape. A male screw is formed around the urging member 8 and is screwed into a female screw formed on the inner surface of the urging member mounting hole 12 of the upper leg 4. Further, as shown in FIG. 3, a concave portion 15 having an opening having a hexagonal shape is provided in the central portion of one surface of the urging member 8, and a through hole 16 is provided in the central portion of the concave portion 15. . A set screw 22 as a protrusion is inserted through the through-hole 16 from the concave portion 15 side of the biasing member 8, and a distal end portion of the set screw 22 is screwed into a pressing member 7 described later. A cylindrical spacer 17 is inserted coaxially with the set screw 22 between the head of the set screw 22 and the bottom surface of the recess 15. It is determined to be located on the opening surface of the recess 15.

  The pressing member 7 is formed in a disc shape. A through hole 18 is provided in the center of the pressing member 7, and a female screw is formed on the inner surface of the through hole 18. Further, the first surface 19 of the pressing member 7 is formed in a flat shape, and the second surface 20 is formed in a loose inclined surface so that the entire pressing member 7 becomes convex from the central portion toward the peripheral portion. Yes. The pressing member 7 is disposed so that the second surface 20 thereof faces the surface 21 of the biasing member 8 on the side where the concave portion 15 is not provided, and the set screw 22 allows play in the axial direction and the radial direction of the set screw 22. In this state, the urging member 8 is gently locked. Accordingly, the pressing member 7 can freely swing within a certain angle with respect to the biasing member 8.

  Since the urging member 8 is screwed to the upper leg portion 4, the interval between the pressing member 7 and the protrusion 3 can be increased or decreased by rotating the urging member 8. Therefore, a member to be pressed (rail, 40 in FIG. 7; the same applies hereinafter) is arranged between the pressing member 7 and the projection 3 so that the biasing member 8 is in a direction in which the interval between the pressing member 7 and the projection 3 is reduced. When rotated, the pressed member is pressed and clamped by the pressing member 7 and the protrusion 3. On the contrary, when the urging member 8 is rotated in the direction in which the distance between the pressing member 7 and the protrusion 3 is increased, the pressing on the pressed member is released. By pressing the pressed member with the pressing member 7 and the protrusion 3, the tip of the protrusion 3 pierces the pressed member, so that the pressed member is securely pressed and held.

  Although the opening of the recess 15 of the biasing member 8 has a hexagonal shape, even if a general-purpose hexagon wrench is to be engaged with the recess 15, the set screw 22 positioned on the opening surface of the recess 15 Since the tip of the head interferes with the tip of the hexagon wrench and the engagement is hindered, the biasing member 8 cannot be rotated unless a hexagon wrench having a special shape as described below is used. The stopper for opening and closing the window according to the present invention is an urging member unless a special tool is used in order to prevent the occurrence of a fall accident such as an infant due to the release of the pressure against the intention of the window manager. It is configured so that it is difficult to rotate 8.

  In the present embodiment, the opening of the booklet 15 has a hexagonal shape, but the shape of the opening is not limited to this, and may be a pentagonal shape, an octagonal shape, etc. as long as it is a polygonal shape. .

  Further, in the present embodiment, the first surface 19 of the pressing member 7 is formed in a flat shape. However, as long as it is not easy to cause a pressing mark on the pressed member, the first surface 19 has a shallow recess at the center. It may be planar. Moreover, in order to prevent generation | occurrence | production of a press mark more effectively, you may make it coat | cover the 1st surface 19 with elastic materials, such as rubber | gum and resin.

  In this embodiment, the urging member 8 screwed to the upper leg portion 4 is used as the urging member urging means. However, for example, a mechanism for urging the pressing member 7 with an insulator installed on the upper leg portion 4. Etc. may be used. Moreover, although the protrusion 3 is provided only in one place of the lower leg part 5, you may provide in multiple places, for example, three places.

FIG. Since the slider 41 cannot move in the opening direction from the position in contact with the window opening / closing stopper S, the opening angle of the window 44 becomes larger than the angle corresponding to the position of the slider 41 defined by the window opening / closing stopper S. There is nothing.

  FIG. 7 is a view showing a cross section taken along line AA of FIG. Since the tip of the protrusion 3 pierces the rail 40, the rail 40 is reliably pressed and clamped by the pressing member 7 and the protrusion 3. At this time, a pressing mark is generated on the rail 40 by the tip of the protrusion 3, but the pressing mark is not noticeable because the protrusion 3 is disposed on the lower surface side of the rail 40 that is not normally touched when the opening degree holding mechanism W is used. .

  In the above description, the window opening / closing stopper S is used for the purpose of preventing the window 44 from opening more than a certain opening angle, but the window opening / closing stopper S is attached in the closing direction of the slider 41. It can be used for the purpose of preventing 44 from closing below a certain opening angle. Furthermore, the opening angle of the window 44 can be kept constant by attaching the window opening / closing stopper S on the rail 40 in contact with both sides of the slider 41.
