Description

The present invention relates to a heat shield plate for a stove that is attached to a wall surface in the vicinity of a table stove, a built-in stove, or the like.

When installing a table stove or built-in stove on a kitchen counter with a wall around it, the fire prevention regulations stipulate the separation distance between the stove and the wall surface in order to prevent heat transfer fire due to the flame of the burner or hot air (for example). If there is combustible material around, 15 cm or more on the side and back of the top plate).
However, due to the design of the kitchen, the stove must be installed close to the back and side walls, and if the separation distance cannot be secured, it is obligatory to attach a heat shield to the wall.
As such a heat insulating plate for a stove, for example, Patent Document 1 includes a fixed heat insulating plate fixed to a wall surface and a secondary heat insulating plate attached to the surface of the fixed heat insulating plate, and is left and right on the surface of the fixed heat insulating plate. While fixing the holding metal fittings with hooks formed on both ends, a pair of left and right L-shaped rails in a plan view are fixed vertically on the back surface of the secondary heat insulating plate, and the secondary heat insulating plate is placed along the surface of the fixed heat insulating plate. The invention is disclosed in which the rails are engaged with the hooks and the auxiliary heat insulating plate is fixed by sliding the rails from above.

JP-A-2006-242437

Since the heat insulating plate for the stove of Patent Document 1 is composed of two heat insulating plates, a fixed heat insulating plate and a secondary heat insulating plate, the number of heat insulating plates increases, which leads to an increase in cost. Therefore, it is conceivable to eliminate the fixed heat insulating plate, attach the holding metal fitting directly to the wall surface, and slide and fix the auxiliary heat insulating plate to the holding metal fitting.
However, if the secondary heat insulating plate is lifted too much upward to clean the top plate or countertop, the rail may come off the hook and the secondary heat insulating plate may fall inward.

Therefore, an object of the present invention is to provide a heat insulating plate for a stove that can be slid upward while being mounted on a wall surface to facilitate cleaning and that does not easily come off when slid upward. It is a thing.

In order to achieve the above object, the invention according to claim 1 is a heat insulating plate for a stove, which is attached to a wall surface located on the outside of the stove.

The hooking metal fitting includes at least two guide metal fittings on the left and right on which the hooking portion on which the metal fitting can be hooked is projected, and the hooking metal fitting has a hooking slit in the vertical direction at which the hooking portion is hooked at the end. The metal fitting is characterized by having a stopper that regulates the vertical movement of the hook metal fitting with a stroke smaller than the stroke of the vertical movement of the hook metal fitting whose hook portion comes off from the hook slit.
The invention according to claim 2 is characterized in that, in the configuration of claim 1, the guide fitting includes a guide portion for guiding the vertical movement of the hook fitting.
The invention according to claim 3 is characterized in that, in the configuration of claim 1 or 2, the hooking portion is a screw member for fixing the guide fitting.
According to the fourth aspect of the present invention, in any of the configurations of the first to third aspects, the guide fitting has a stopper mounting portion at a vertically symmetrical position about the hooking portion, and the stopper is one of the stoppers. It is characterized in that it can be attached to the stopper attachment portion.

According to the first aspect of the present invention, since the stopper regulates the sliding of the heat insulating plate body to the position where the heat insulating plate main body comes off, the heat insulating plate main body can be slid upward to easily clean the top plate and the counter top. There is no risk that the heat shield body will come off when it is slid upward.
According to the second aspect of the present invention, in addition to the effect of the first aspect, the guide portion provided on the guide fitting allows the heat insulating plate main body to be smoothly moved up and down via the hook fitting.
According to the third aspect of the present invention, in addition to the effects of the first or second aspect, a rational configuration in which the screw member is also used as the hooking portion is obtained, and the number of parts can be reduced.

FIG. 1 is an exploded perspective view showing an example of a heat insulating plate for a stove, FIG. 2 is a rear view of the heat insulating plate main body, and the upper left side of FIG. 1 is the front. The heat shield plate 1 for the stove guides the heat shield plate main body 2, the three hook metal fittings 3, 3 ... Fixed to the back surface of the heat shield plate main body 2, and the hook metal fittings 3, 3 ... Attached to the wall surface. It includes guide metal fittings 4, 4, and so on.
The heat insulating plate main body 2 is formed by attaching a stainless steel plate 6 which is also a noncombustible material to the surface of a gypsum board 5 which is a noncombustible material having a rectangular front view.
The hook metal fitting 3 is formed by bending a metal plate, and the back plate portion 7 parallel to the heat insulating plate main body 2 and a pair of side plate portions 8 and 8 bent at right angles from both left and right sides of the back plate portion 7 to the front. And a pair of overhanging portions 9 and 9 that are bent outward from the front ends of the plate portions 8 and 8 on both sides.

An upper plate portion 10 extends from the upper end of the back plate portion 7 and is bent between the left and right side plate portions 8 and 8 to close the space between the side plate portions 8 and 8. Further, a hook slit 11 is formed in the lower center of the back plate portion 7 from the lower end to the upper side. The hook slit 11 is formed of a wide portion 12 at the lower end, a narrow portion 13 whose upper end is closed in an inverted U shape, and a tapered portion 14 connecting the wide portion 12 and the narrow portion 13. , The width changes in the vertical direction.
As shown in FIG. 2, the hook metal fitting 3 is formed by fixing the overhanging portions 9 and 9 with screws 15 and 15 at three locations on the back surface of the heat insulating plate main body 2 at the upper left and right and the lower center. It is integrated with the heat insulating plate main body 2 so that the plate portion 10 is on the top and the hook slit 11 is on the bottom.

The guide metal fitting 4 is formed by bending a metal plate to form a vertically long rectangular bottom plate portion 16, a stopper mounting portion 17 that is bent from the upper end of the bottom plate portion 16 to the front side, and the bottom plate portion 16 from both left and right sides to the front side. It is provided with a pair of guide portions 18 and 18 to be bent. A screw hole 19 is formed in the center of the stopper mounting portion 17 in the left-right direction. Further, a through hole 20 is formed in the center of the lower end of the bottom plate portion 16, and mounting pieces 21 and 21 projecting from below the guide portions 18 and 18 to the left and right outside are extended to each mounting piece 21. Through holes 22 are formed respectively. The distance between the left and right guide portions 18 and 18 is set so that the hook metal fittings 3 can be accommodated except for the overhanging portions 9 and 9, and the hook metal fittings 3 are housed between the guide portions 18 and 18. The slides in the vertical direction are guided by the guide portions 18 and 18.

In the heat insulating plate 1 for the stove configured as described above, on the wall surface for fixing the heat insulating plate main body 2, guide metal fittings 4, 4 ... Are provided at three places corresponding to the hook metal fittings 3, 3 ..., and the stopper mounting portion 17 Install with the top side. In this case, the hook screw 23A as a screw member penetrating the through hole 20 in the center of the bottom plate portion 16 and the mounting screws 23B and 23B penetrating the through hole 22 of each mounting piece 21 are screwed into the wall surface. However, here, the hook screw 23A screwed into the central through hole 20 is screwed in according to the upper end position of the hook slit 11 of the hook metal fitting 3. This is the supporting height of the heat insulating plate main body 2.

However, as shown in FIG. 3B, the center set screw 23A has a state in which a distance larger than the thickness of the back plate portion 7 of the hook fitting 3 is secured between the screw head 24A and the bottom plate portion 16. Stop screwing into the wall surface W with. The left and right mounting screws 23B and 23B on the mounting pieces 21 and 21 are screwed into the wall surface W until the screw head 24B abuts on the mounting piece 21.
In the state where the guide metal fitting 4 is attached to the wall surface W in this way, the vertical distance between the central hook screw 23A and the stopper mounting portion 17 is slightly shorter than the vertical dimension of the hook metal fitting 3, and the guide portion 18, In the state of FIG. 3 in which the upper plate portion 10 of the hook fitting 3 pushed in between 18 abuts on the stopper mounting portion 17, the screw head 24A is located in the wide portion 12 and the tapered portion 14 of the hooking slit 11. It is designed so as not to interfere with the back plate portion 7 in the front-rear direction.

Therefore, the heat insulating plate main body 2 is fitted to the wall surface W to which the guide metal fittings 4, 4, ... Are attached, from below the stopper mounting portion 17 of each guide metal fitting 4, and between the guide portions 18, 18. Then, the screw head 24A of the hook screw 23A penetrates the wide portion 12 and the tapered portion 14 of the hook slit 11 and projects forward of the back plate portion 7.
When the heat insulating plate main body 2 is slid downward from here, each hooking metal fitting 3 descends between the guide portions 18 and 18 of each guide metal fitting 4, so that the hooking screw 23A relatively rises in the hooking slit 11. Then, as shown in FIG. 4, it is hooked on the upper end of the narrow portion 13. Therefore, at that position, the heat insulating plate main body 2 is suspended and supported by three hook screws 23A, 23A, etc. via the three hook metal fittings 3, 3, ....

Since the narrow portion 13 of the hook slit 11 through which the hook screw 23A penetrates has a width smaller than the outer diameter of the screw head 24A, the back plate portion 7 is prevented from coming off by the screw head 24A, and the heat insulating plate main body. 2 does not fall in the direction away from the wall surface W. Therefore, if the heights of the guide fittings 4, 4, ... Are set so that the lower end of the heat insulating plate main body 2 comes into contact with the top plate of the built-in stove, the counter top of the kitchen, etc. while being suspended and supported, the stove The surrounding wall surface W is protected by the heat insulating plate main body 2. The same applies when a plurality of heat insulating plate main bodies 2 are provided.

Finally, as shown in FIG. 5, the stopper screw 25 as a stopper is screwed into the screw hole 19 of the stopper mounting portion 17 of each guide fitting 4 from above, and the stopper screw 25 is projected below the stopper mounting portion 17. .. At this time, in the stroke S1 that can move up and down until the hook metal fitting 3 comes into contact with the lower end of the stopper screw 25, the hook screw 23A at the upper end of the narrow portion 13 moves up and down relatively into the tapered portion 14 from which the screw head 24A comes off. It is smaller than the stroke S2 that can be made. That is, even if the hook metal fitting 3 slides upward until the upper plate portion 10 abuts on the stopper screw 25, the state in which the screw head 24A is locked to the back plate portion 7 in the narrow portion 13 is maintained and hooked. It is set so that it does not come off from the stop slit 11.

Therefore, when cleaning the top plate or the countertop, if the heat insulating plate main body 2 is slid upward, a gap is formed between the top plates and the like, so that the upper surface of the top plate and the like can be easily cleaned. At this time, the upward slide of the heat insulating plate main body 2 is restricted at the position where the hooking metal fitting 3 is prevented from coming off by the hook screw 23A, so that there is no possibility that the heat insulating plate main body 2 accidentally comes off during cleaning.
When it becomes necessary to remove the heat insulating plate main body 2, the stopper screw 25 is removed from each guide metal fitting 4, and the heat insulating plate main body 2 is slid upward until the hook metal fitting 3 comes into contact with the stopper mounting portion 17, and the hook is hooked. It can be taken out toward you without interfering with the set screw 23A.

The hooking metal fittings 3 include the guide metal fittings 4, 4, and the hooking screws 23A, which are fixed to the wall surface W and can be hooked by the hooking metal fittings 3, respectively. The guide fitting 4 has a hooking slit 11 that is hooked at the end in the vertical direction, and the hooking metal fitting 4 has a stroke S1 that is smaller than the vertical movement stroke S2 of the hooking metal fitting 3 in which the hooking screw 23A comes off from the hooking slit 11. By having the stopper screw 25 that regulates the vertical movement of the heat insulating plate body 2, the sliding of the heat insulating plate main body 2 to the position where it comes off is restricted, so that the heat insulating plate main body 2 can be slid upward to easily clean the top plate and the counter top. At the same time, there is no possibility that the heat insulating plate main body 2 will come off when the heat insulating plate body 2 is slid upward.

In particular, here, by providing the guide metal fittings 4 with guide portions 18 and 18 for guiding the vertical movement of the hook metal fitting 3, the heat insulating plate main body 2 can be smoothly moved up and down via the hook metal fitting 3.
Further, since the hooking portion is a hooking screw 23A for fixing the guide metal fitting 4, the hooking screw 23A is also used as the hooking portion, and the number of parts can be reduced.

In the above embodiment, the stopper mounting portion 17 of the guide fitting 4 is provided with a screw hole 19 and the stopper screw 25 is screwed from above. However, as shown in FIG. 6, a screw hole is provided in one of the left and right guide portions 18. 19 may be provided and the stopper screw 25 may be screwed from the side so as to project forward of the bottom plate portion 16. In this case as well, it is possible to regulate the vertical movement of the hook metal fitting 3. In addition to screws, other members such as rods and plates can be used as stoppers, but screws have the advantage of being able to change the protruding length (regulated position).

Further, as in the guide metal fitting 4A shown in FIG. 7, a pair of bottom plate portions 16 and 16 are formed at vertically symmetrical positions centered on the mounting pieces 21 and 21 provided with the through holes 20 and 22. Each bottom plate portion 16 may be provided with a stopper mounting portion 17 having a screw hole 19 and guide portions 18 and 18, respectively, so that the stopper screw 25 can be mounted on either of the stopper mounting portions 17. By doing so, the guide metal fitting 4A can be used in either the vertical direction, and there is no work error when attaching the guide metal fitting 4A to the wall surface W or the like. This also applies to the case of FIG. 6 in which the stopper screw 25 is screwed into the guide portion 18 from the side, and screw holes 19 may be provided in the upper and lower guide portions 18, respectively.

Furthermore, in addition to using the hooking screw 23A as the hooking part, a dedicated hooking part may be provided by fixing a stud bolt or the like directly to the guide fitting or using a screw screwed only into the guide fitting. Is also possible.
In the above embodiment, the hook metal fittings are fixed to the heat insulating plate main body and the guide metal fittings are fixed to the wall surface. On the contrary, the guide metal fittings may be fixed to the heat insulating plate main body and the hook metal fittings may be fixed to the wall surface. Absent. However, in this case, the hooking slit on the wall surface side is formed from the upper end and the hooking portion on the heat insulating plate main body side is hooked from above, and the guide metal fitting on the heat insulating plate main body side is below the hooking portion. On the side, a stopper that comes into contact with the hook metal fitting and regulates the upward slide of the heat insulating plate main body will be provided.
