Description

The claimed device relates to furniture production, as well as to accessories for the production of sliding window and door structures, sliding fencing structures used in construction, sliding furniture sashes.

This device is a device for securing and adjusting the roller inside the profile of the leaves of sliding structures, such as doors, windows, balcony fences and other structures that overlap technological openings.

The closest analogue of the claimed device for fixing and adjusting the roller inside the profile for windows and doors is described in the electronic source on the bestwind.ru website in the PROVEDAL hardware section: http://bestwind.ru/index.php?id=379 (on the website [Figure 1.2 p. 5]).

The case consists of parallel walls, each of which has two inclined guide slots at an angle α = 45 °, into which a slider is inserted, end walls (right and left) and a platform for a fixing screw, which is located between the parallel walls and is interfaced with from the end walls. In one of the end walls there is a hole for an adjusting screw made during the additional operation of drilling the wall. The other end wall is made without a hole.

The slider consists of two parallel walls and two side walls. On the parallel walls there are protrusions for moving the slider along the slots of the housing. The closest analogue is illustrated in FIG. 12.

In FIG. 1 is a side view; FIG. 2 shows a top view.

The disadvantage of the closest analogue is the too high cost of the product, which consists in the fact that it takes a lot of cast alloy to cast the structure, and it also takes a lot of time to assemble the finished product, due to the need for accurate positioning of the parts relative to each other when installing the slider in the case, which is essential increases assembly time. Also, it takes a lot of time to remove the structure from the mold, due to the pointed edges of the structure.

The problem to be solved in the design of the claimed device was to reduce the cost of construction by reducing the mass of the housing, as well as reducing the assembly time.

The technical result is to reduce the cost of construction while maintaining the strength characteristics of the structure itself.

Essence: a device for furniture and construction production, for moving movable floors of technological openings and doors, includes: a housing, a roller, a slider, fixing and adjusting screws. The housing is used for positioning, securing and providing the ability to adjust the position of the roller inside the sash. The roller serves to move the sash along the guide. The fixing screw is used to secure the housing inside the sash. The adjusting screw sets the position of the slide with the roller relative to the housing.

The utility model relates to the field of construction and furniture production, in particular to fittings used for glazing windows or doors, and in particular to devices for securing movable doors, windows, balcony rails and other structures that overlap technological openings, as well as for furniture structures such as a wardrobe.

In general terms, the claimed device is a device for securing and adjusting the roller inside the profile of the leafs of the sliding structures, including a slider with a roller placed in a housing consisting of two parallel horizontally elongated horizontal walls with two inclined slots made at an angle α = 45 ° on each wall and with through holes, one in each of the walls, and two end walls, different in thickness, and in the upper part of the body there is a platform with a hole for a fixing screw located between horizontally washed by parallel walls and conjugated with the left end wall, on the right end wall, which is thicker, there is a protrusion in the form of a truncated cone with a hole for the adjustment screw that sets the position of the slider with the roller inside the housing, and the slider consists of two end walls of two side walls between which the roller is fixed, and on the outer side of the side walls of the slider there are protrusions placed in inclined slots of horizontally elongated parallel walls of the housing, which ensure The slider moves along the slots, while the hole for the adjustment screw in the protrusion on the right end wall of the body is chamfered, the right end wall in thickness is made with a bevel parallel to the slope of the slots located in the horizontally elongated parallel walls of the body, and the corners in places connections of the end walls with horizontally elongated parallel walls inside the body are rounded.

The body and slider of the device are made of zinc cast alloy TsAM 4-1.

The housing of the claimed device is illustrated in FIG. 3, 4. In FIG. 3 is a side view; FIG. 4 shows a top view.

In the case, the holes are made by casting, which reduces the number of operations, compared with the closest analogue. This leads to significant changes in the design of the mold for the manufacture of the housing of the claimed device.

To reduce the assembly time in the housing of the claimed device, rounding of the sharp edges of the inclined slots is performed.

To reduce the cost of designing a utility model, the mass of the case has been reduced, but all the strength characteristics presented to the device’s body have been preserved.

Differences from this case:

мм и общая длина корпуса составила

мм, что привело к изменению толщины задней торцевой стенки. Это позволило снизить массу корпуса;• The side walls of the housing compared to the closest analogue are reduced in length by a distance

mm and the total body length was

mm, which led to a change in the thickness of the rear end wall. This allowed to reduce the mass of the body;

• The thickness of the rear end wall of the housing is reduced by 1.5 mm;

• Due to a decrease in the thickness of the right end wall of the housing, we add fillets to the surface of the wall facing the inner side of the part connecting the two walls for a more uniform load distribution;

• On the left and right end walls, we make a bevel parallel to the guide slots in the side walls, which will reduce the mass of the housing and facilitate the removal of the slider and its installation in the housing;

• The surface of the protrusion on the right end wall is made in the form of a truncated cone, which reduces the mass of the part and simplifies the extraction of the casting from the mold;

• In the protrusion in the form of a truncated cone, make a hole. The manufacture of this hole will lead to a decrease in technological operations during the production of the part, in particular in this case, the additional operation of drilling the wall of the hole for the adjustment screw, which is necessary when manufacturing the device from the closest analogue, is excluded;

• The hole is immediately chamfered. This will simplify the alignment of the tap when threading and increase the stroke of the adjusting screw;

• On the upper part of the right end wall we will make a cylindrical protrusion, which will allow you to get a round platform. It is necessary to abut the pusher when pushing the casting out of the mold;

• On the parallel walls elongated horizontally, at the edges of the inclined slots facing outward, fillets are made to simplify the installation of the slider in the housing;

• In horizontally elongated parallel walls between inclined slots, we make through holes to reduce the mass of the casting;

• In the left end wall of the casing, roundings were made between the end wall and the parallel walls of the part elongated horizontally. The made rounding allows you to remove internal stresses, which positively affects the strength of the housing.

• We remove part of the sides in the area of the fixing screw. Rounding out corners. This reduces the weight of the housing.

• For faster fixing of the slider inside the body, the right end wall of the body is made with a bevel in thickness with a bevel parallel to the slope of the slots located in the horizontally elongated parallel walls of the body.

Thus, by the combination of the above changes in the details, we have achieved a reduction in the casting mass and a reduction in the time taken to remove the device body from the mold and the assembly time of the finished product, thanks to unhindered extraction from the mold and the reduction in the number of technological operations.

As a result of the above changes, the cost of the material needed to make the case in the nearest prototype is 5.1 rubles (we Accept that 1 kg of TsAM 4-1 costs 170 rubles / kg), and the price of the case in the claimed device was 4.59 rubles. What clearly shows the reduction in cost, taking into account the difference in a single case, as well as taking into account the reduction in assembly time associated with a decrease in the positioning time of the slider in the housing, when using the claimed device in industrial volumes, the difference in cost will be even greater.

To clarify the essence of the utility model in FIG. 3, 4 shows a diagram of the changed part of the part - the housing.

In FIG. 5 shows a side view of the layout of the claimed device with a housing made of transparent plastic to explain the internal arrangement of all components.

In FIG. 6 shows a top view of the layout of the claimed device with a housing made of transparent plastic.

The operation of the device is as follows.

The device is going to first. A roller is inserted into the slider. Next, a slider with a roller is inserted into the housing and fixed with the adjusting screw. Further, the entire part is inserted into the sash profile, where it is attached with a fixing screw and the height of the slider with the roller is set with the adjusting screw.

The device is installed in the following order:

1. Cut the thread into two holes;

2. Screw in the fixing screw;

3. Insert the roller into the slider;

4. Insert the slider with the roller into the housing and fasten it with the screw.

5. Insert the device into the sash profile;

6. Fasten and adjust the position of the device in the sash profile.
