Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a sash with a surface lattice, and more specifically, to an improvement in the structure for attaching the sash to the sash body.

[Conventional technology]

BACKGROUND OF THE INVENTION Conventionally, grids have been attached to sashes for decoration and theft prevention purposes. In this case, the conventional structure for attaching the surface lattice to the sash is, as shown in FIG. And the lower horizontal member f is fixed along the length direction of the vertical member g with screws h, h.

[The problem that the idea aims to solve]

However, in a screw fastening structure in which screws h and h are inserted along the length direction of the vertical member g as shown in Fig. 4, the driver i is inserted between the face grating d and the sash body a as shown in Fig. 4. Insert it between the screwdriver i
are arranged along the insertion direction of the screws h, h, that is, along the length direction of the vertical member g, and since it is easy to remove the screws h, h, the surface grating d can be easily removed from the sash body a. . For this reason, the conventional structure for attaching the surface grid to the sash body has a problem in terms of theft prevention.

Additionally, a mounting structure is known in which the screws are arranged diagonally and the surface grid is screwed diagonally to the sash body (Utility Model Application Publication No. 54-24234, Publication No. 55-123595). However, this type of conventional mounting method using screws at an angle is cumbersome to operate.

That is, in the former case, when attaching the screen grid to the window frame body, it is screwed diagonally, but in this mounting structure, the hook part of the upper bracket is hooked to the hook part of the upper side grid mounting plate. At the same time, after the hooking part of the lower bracket is hooked to the hooking part of the lower side grid mounting plate, it is screwed down.When holding the grid on the window frame body, it is necessary to attach it to the hooking part of the lower side grid mounting plate at two places, upper and lower, as shown above. Since each grid must be latched, the work of latching the grid to the window frame body is troublesome.

Similarly to the former mounting structure, when the sash is used to hold the lattice, the mounting structure for the lattice on the latter sash is such that when the sash is used to hold the lattice, the upper frame and the upper crosspiece, and the lower frame and the lower crosspiece are fitted in two places, one above and the other. In addition, the structure for fitting the upper frame and the upper frame, and the lower frame and the lower frame, respectively, is complicated and expensive.

The present invention was made to improve the above-mentioned situation, and the surface lattice can be rotatably held on the sash body by simply hooking the surface lattice on the sash body in one place. To provide a sash with a surface lattice that is easy to tighten with screws and can be easily operated by one person, and is difficult to remove from the outside after the sash is attached to the sash body, and is effective in preventing theft. The purpose is to

[Means to solve the problem]

In order to achieve the above-mentioned purpose, the present invention has a surface lattice formed by screwing the upper side member and the lower side member for attaching the surface lattice to the upper side member attachment part and the lower side member attachment part of the sash body, respectively. In the attached sash, the upper horizontal member attachment part of the sash body has a horizontal wall, a vertical wall integrally protruding from the tip thereof, and a vertical wall integrally protruding from the tip thereof, and a screw threading hole is bored therein. a downward sloping wall;
It has an upward locking wall integrally protruding from its tip, and the upper mounting cross member of the above-mentioned surface lattice is protruded from the horizontal wall and the lower surface of the horizontal wall, and the above-mentioned upper side member is protruded from the horizontal wall and the lower surface of the horizontal wall. It has an inclined cylindrical screw fixing part formed with a female screw part that engages with a screw inserted through the threading hole in the downwardly inclined wall of the horizontal member mounting part, and the tip of the horizontal wall is connected to the vertical wall. and the tip of the screw-fastening part is brought into contact with the downwardly inclined wall, and the female thread part of the inclined cylindrical screw-fastening part of the upper mounting horizontal member of the face grating is connected to the screw thread of the downwardly inclined wall. Screw in and fasten the screws arranged diagonally from the matching holes, and provide an inclined wall at the tip of the lower cross member attachment part, and also provide an inclined screw fixing part to the lower cross member for attachment of the above-mentioned face grating. is provided, and the inclined wall of the lower cross member attachment portion and the inclined screw fixing portion of the lower cross member for attachment are screwed together with screws arranged in an oblique direction.

[Effect]

The sash with a surface lattice of the present invention has a configuration in which the upper horizontal member attachment part of the sash body has a horizontal wall, a vertical wall, a downwardly sloping wall, and a locking wall connected in sequence. A concave portion is formed by the inclined wall and the locking wall, and the horizontal wall whose tip is in contact with the vertical wall, and a horizontal wall whose tip is in contact with the vertical wall, and a horizontal wall that protrudes from the lower surface of the horizontal wall and are connected to the locking wall. It is configured to have an inclined cylindrical screw stopper whose tip abuts on the inner surface of the locking wall, so that the tip of the horizontal wall comes into contact with the vertical wall, and the tip of the cylindrical screw stopper comes into contact with the inner surface of the stopper wall. As a result, the horizontal wall and the cylindrical screw fixing part are engaged with the recessed part, and the upper cross member for attaching the face grid is rotatably latched to the upper cross member attaching part of the sash main body, and its own weight is It is suspended from the

Therefore, when attaching the grid to the sash body, the tip of the horizontal wall of the upper mounting horizontal member of the grid should be brought into contact with the inner surface of the vertical wall of the sash body, and the tip of the slanted cylindrical screw fixing part should be attached to the sash body. hook it in contact with the inner surface of the locking wall, then rotate the face grid to draw the lower cross member to the lower cross member attachment part, and lower the slanted screw fixing part of the lower cross member for installation. Bring it into contact with the inclined wall of the side horizontal member attachment part, and in this state, screw the inclined screw-fastening part of the lower mounting cross-piece and the inclined wall, and also tighten the screw-fastening part of the upper mounting cross-piece and the downward slope. It can be fixed to the wall with screws, and therefore, the surface lattice can be held on the sash body with only one hooking operation, that is, hooking the upper side mounting cross member of the surface lattice to the upper side cross member attachment part of the sash body. In this state, the grille can be attached to the sash body by simply turning it and tightening the screws diagonally.The installation operation is extremely simple, and even one person can easily attach the grille to the sash body. .

In addition, in this case, the screw-fastening part of the upper horizontal member is cylindrical with a female thread formed on the inner circumferential surface, so it cannot be bored into the downwardly inclined wall of the upper horizontal member attachment part of the sash body. The screw inserted through the threaded screw hole is firmly engaged and held by the female thread on the inner circumferential surface of the cylindrical screw fixing part, and the screw can be strongly tightened without the need for a washer. The horizontal member mounting part and the upper side mounting horizontal member of the surface grid can be firmly and easily screwed together.

In addition, the upper mounting cross member for holding the surface grid on the sash body in this way can be made by simply bending the material into the configuration (shape) described above, while the upper cross member mounting portion is also cylindrical on the horizontal wall. It is only necessary to provide the screw-fastening part in a protruding manner, and in this case, the cylindrical screw-fastening part plays the role of a screw-fastening member and at the same time as an engaging member that engages with the recessed part of the upper mounting cross member. Therefore, the structure of the upper side mounting cross member and the upper side cross member attachment portion is simple and can be manufactured at low cost.

Furthermore, according to the sash with a surface lattice of the present invention, the screws for attaching the sash body to the surface lattice are arranged diagonally in a state that is inclined to the length direction of the vertical members of the surface lattice, and the screws for attaching the surface lattice and the sash body are screwed in place with these diagonally arranged screws, so if you want to remove the face lattice from the sash body from the outside, be sure to insert it between the face lattice and the sash body in a direction that matches the direction of insertion of the screws. You have to insert the screwdriver diagonally, but if you try to insert the screwdriver diagonally like this, the rear of the screwdriver will hit the door or window attached to the satsushi body.
It is difficult to insert the driver diagonally. For this reason, it is difficult to remove the screws that attach the face lattice and the sash body from the outside, and therefore it is difficult to remove the face lattice from the sash body.
It is effective in preventing theft.

This bracket 11 includes a horizontal wall 13, a vertical wall 14 integrally protruding from the upper edge of the distal end thereof, and an upper wall 14 integrally protruding from the distal end thereof that slopes upward from the proximal end toward the distal end. The upwardly inclined wall 15 is provided with a threaded hole 16.

17 is a frame-like body formed by fixing an upper mounting horizontal member 19 and a lower mounting horizontal member 20 to the upper and lower parts of the left and right vertical members 18 (only one vertical member is shown in the drawing), respectively. This is a surface lattice equipped with a lattice body (not shown) which is made by combining the crosspieces in a lattice shape.

The upper mounting horizontal member 19 of this surface lattice 17 is
a vertical wall 22 that comes into contact with and is attached to the inner surface of the vertical member 18; a horizontal wall 23 that projects integrally from the inner edge of the upper end and whose tip can come into contact with the vertical wall 7 of the upper frame 5; It is integrally provided on the inner surface of this horizontal wall 23 in a downwardly inclined state from the proximal end toward the distal end, and the distal end can come into contact with the locking wall 9 of the upper frame 5, and the inner peripheral surface It is composed of an inclined cylindrical screw fixing part 25 in which a female thread part 24 is formed. The tip end surface of this screw fixing part 25 comes into contact with the top surface of the downwardly inclined wall 8 at the tip of the upper frame 5 of the sash main body 1, and the screw 26 is screwed through the screw threading hole 10 of this inclined wall 8. The female screw portion 24 of the screwed portion 25 is inserted diagonally into the screw portion 25.
By being screwed together, the upper mounting cross member 19 of the surface lattice 17 is fixed to the upper frame (upper cross member attachment portion) 5 of the sash main body 1.

In addition, the lower mounting horizontal member 20 of the surface lattice 17 comes into contact with the inner surface of the vertical member 18 and has a vertical wall 27 attached thereto, and a horizontal wall 28 integrally protruding from the inner edge of the lower end thereof. , an engagement wall 29 integrally protruding from the top edge of the horizontal wall 28 and abutting and engaging with the vertical wall 14 of the bracket 11;
An upwardly inclined wall-shaped screw fixing portion 30 is integrally provided at the distal end of the bracket 11 in a diagonally upwardly protruding state and is in opposing contact with the upwardly inclined wall 15 of the bracket 11, and an inner edge of the upper end of the vertical wall 27. The protective wall 31 is formed integrally with the protective wall 31 in a horizontally protruding state. Then, the screw 33 is inserted diagonally from the screw hole 16 of the upwardly inclined wall 15 of the bracket 11 into the screw hole 32 of the screw stopper 30, and is screwed thereto.
The horizontal member 20 for mounting on the lower side of the surface lattice 17 is the sash main body 1
It is fixed to the bracket (lower side member attachment part) 11.

According to the above-mentioned sash with a surface grid, the upper and lower mounting cross members 19 and 20 of the surface grid 17 are respectively attached to the upper frame (upper cross member attachment portion) of the sash main body 1.
5 and the bracket (lower side member attachment part) 11, the screws 26 and 33 are inclined with respect to the length direction of the vertical member 18 of the surface lattice 17, and the screw parts 25, 33 are inclined along the diagonal direction. 30 and are screwed together, so when the surface lattice 17 is attached to the sash body 1, the surface lattice 17 can be inserted from the outside.
If you want to remove the screws, insert a screwdriver between the surface grating 17 and the sash body 1, place the screwdriver diagonally along the insertion direction of the screws 26 and 33, and remove the screws 26 and 33. However, if the screwdriver is inserted diagonally, the rear of the screwdriver will come into contact with the door attached to the sash body 1, making it difficult to insert the screwdriver in the same direction as the diagonal insertion direction of the screws 26 and 33. ,
Since the screws 26 and 33 cannot be removed, it is difficult to remove the surface lattice 17 from the sash body 1, which is effective in preventing theft.

When attaching the surface grid 17 to the sash body 1, first attach the surface grid 17 to the sash body 1 as shown in FIG.
The tip of the horizontal wall of the upper mounting horizontal member 19 is brought into contact with the inner surface of the vertical wall 7 of the upper frame 5 of the sash body 1, and the tip of the inclined cylindrical screw part 25 is brought into contact with the upper frame 5 of the sash body 1.

After screwing the screwing part 30 of the mounting horizontal member 20 and the upwardly inclined wall 15 of the bracket 11, the screwing part 25 of the upper mounting horizontal member 19 and the downwardly inclined wall 8 of the upper frame 5 are screwed together. Stop it.
Finally, the door is attached to the sash main body 1.

Therefore, when attaching the above-mentioned sash with a surface lattice to the sash body 1, the sash 17 can be screwed in with the surface lattice 17 hooked onto the sash body 1 at only one place, so it can be screwed in place by one person. It can be installed and the installation operation is easy.

Moreover, since the screw fixing part 25 of the upper mounting horizontal member 19 is cylindrical with a female thread part 24 formed on the inner peripheral surface, a screw inserted from the screw threading hole 10 of the downwardly inclined wall 8 26 is screwed into and held by this female threaded portion 24, and in this case, it can be strongly tightened without the need for washers, so that the screwed portion 25 of the upper mounting horizontal member 19 and the upper frame 5 are inclined downwardly. The wall 8 can be easily and firmly screwed together.

In addition, in the present invention, the structure of the upper frame (upper cross member attachment part) and bracket (lower cross member attachment part) of the sash body, and the structure of the upper cross member and lower cross member of the face grid are the same as those of the illustrated embodiment. It goes without saying that the present invention is not limited, and that various changes can be made without departing from the gist of the present invention, and other configurations can also be changed as appropriate.

[Effect of idea]

As explained above, according to the sash with a face lattice of the present invention, the upper side of the lattice is placed in the recessed part formed by the vertical wall, the downwardly inclined wall, and the locking wall of the upper cross member attachment part of the sash main body. By simply engaging the horizontal wall of the mounting horizontal member and the cylindrical screw fixing part, the face grid can be rotatably latched onto the sash body and suspended by its own weight. By simply rotating the latched face grid, the lower side mounting cross member of the face grid can be easily drawn to the lower side cross member attachment portion of the sash main body. Therefore, when tightening the screws, the face grid can be held on the sash body by simply hooking it on the sash body at one point. Therefore, the operation of holding and attaching the face grid on the sash body is easy, and only one person can perform the installation operation. In addition, the configuration of the upper side mounting cross member and the upper side cross member attachment portion for holding the surface lattice on the sash body is simple and can be manufactured at low cost. In addition, since the screw fixing part of the upper horizontal member for attaching the face grid is cylindrical with a female threaded part formed on the inner circumferential surface, it is necessary to drill into the downwardly sloping wall of the upper horizontal member attachment part of the sash body. The screws inserted through the screw holes can be firmly screwed and held, and the upper side mounting crosspiece of the face lattice and the upper side crosspiece attachment part of the sash body can be firmly and easily screwed together.
Furthermore, the screws that attach the lattice and the sash body are inserted diagonally in a state that is inclined to the length direction of the vertical members of the lattice, and the lattice and the sash body are screwed together. Even if you try to remove a screw by inserting a screwdriver between the face grating and the sash body, you will not be able to remove the screw unless you insert the screwdriver diagonally. It is difficult to insert the screwdriver diagonally because the rear part of the screwdriver comes into contact with the door or window attached to the sash body. Therefore, it is difficult to remove the screws from the outside, making it difficult to remove the face grating from the sash body, which prevents theft. It is highly effective.
