Description

Technical Field

[0001] This invention relates to the field of door and window manufacturing tools, and particularly to a door and window mullion positioning ruler. This invention also relates to a positioning method for this door and window mullion positioning ruler. Background Technology

[0002] Doors and windows typically require a mullion for horizontal or vertical division. Therefore, during door and window manufacturing, a mullion component needs to be installed in the middle of the door and window frame profile before the mullion is installed on top of it. The accuracy of the mullion's installation position directly affects the stability and lifespan of the doors and windows; therefore, precise measurement methods are crucial.

[0003] In existing technology, the dimensions of the door and window openings are first confirmed, the door and window frames are installed in place, and using a measuring tape and calipers, lines are marked on the frame or mullion according to the column dimensions with a marker. Then, the mullion or its inner clamp is visually fixed at the line positions. If the door and window openings are irregular or there are obstacles, the measurement position needs to be adjusted. In actual construction, to improve the accuracy of the mullion position, the distance from one side of the mullion to both sides of the window frame needs to be checked again to ensure accuracy before installing the mullion. This adds an inspection step to the installation process, reducing the efficiency of mullion installation.

[0004] The positioning of the mullion is determined by the distance from the center line of the inner code to the starting 0 point. If either the starting 0 point or the center line of the inner code is not accurately positioned, it will directly lead to inaccurate mullion positioning. First, if one end of the T-shaped connection of the mullion is inaccurate, it will affect the diagonal dimensions of adjacent openings or solid glass openings, causing the deviation to exceed the allowable range. This will also cause the overlap of the sealing strip of the opening to shift, resulting in a failure to overlap or the opening touching the sealing strip, reducing the overall airtightness, watertightness, and thermal insulation of the window.

[0005] Secondly, it will severely affect the optimal alignment of the frame hardware and the sash hardware, requiring readjustment and reinstallation of the hardware. Thirdly, the non-perpendicular nature of the T-joints results in a loose fit on one side of the visible shoulder seam at the mullion end, affecting the aesthetic appearance. Summary of the Invention

[0006] In view of this, the present invention aims to provide a positioning ruler for door and window mullions, which can directly determine the position of the mullion on the door and window frame without the need for marking and complicated measurement steps, thereby improving the positional accuracy of mullion installation, reducing the mullion positioning steps, and improving the mullion installation efficiency.

[0007] To achieve the above objectives, the technical solution of the present invention is implemented as follows: A door and window stile positioning ruler includes a body having an insertion space, a top block inserted into the insertion space, and a scale connecting the top block and the inner wall of the body. The ruler is provided with a first positioning block at one end, which is used to locate the position of the mullion. The body is provided with a second positioning block, which is used to abut against the door and window frame profile to determine the starting point of the positioning ruler. The starting scale value of the scale is equal to the length value of the body, and the starting scale of the scale is set at one end close to the first positioning block.

[0008] Furthermore, the body includes a base plate and an arc-shaped member protruding to one side from the base plate; The bow-shaped member and the base plate form the insertion space; The base plate is provided with a plurality of first mounting parts, and the top block is provided with a first mating part corresponding to the first mounting parts. The top block is fixed to the body by bolts.

[0009] Furthermore, the side of the base plate facing away from the bow-shaped member is provided with a T-shaped protrusion, and a groove is formed between the protrusion and the base plate. The groove is used to be inserted into the rib of the door and window frame profile.

[0010] Furthermore, the base plate is also provided with a long strip-shaped support block, which is formed within the insertion space; The top block has a long groove formed along its length, and the long groove is adapted to abut against the upper part of the support block; The first mounting part penetrates the base plate and the support block.

[0011] Furthermore, the contact portion between the top block and the scale is formed in a triangular shape, the longitudinal section of the scale is formed in a "V" shape, and the contact portion of the bow-shaped member is adapted to the shape of the scale.

[0012] Furthermore, the scale is provided with a mounting plate at one end near the first positioning block, and the mounting plate is provided with a second mounting part, through which the first positioning block is fixed to the mounting plate; The first positioning block is also provided with two spaced-apart opening slots, which are symmetrically formed on both sides of the second mounting part. The mounting plate is provided with a pin protruding outward, and the diameter of the pin is adapted to the inner diameter of the opening slot.

[0013] Furthermore, the second positioning block is formed into a triangle, and one corner of the second positioning block is provided with an abutment surface. The second positioning block is detachably connected to the base plate. When the contact surface abuts against the side of the protrusion, the positioning ruler is in a first measuring form; The two sides of the contact surface are connected by right-angled surfaces. When any of the right-angled surfaces abuts against the side of the protrusion, the positioning ruler is in a second measuring form.

[0014] Furthermore, the base plate is provided with a third mounting portion and a fourth mounting portion spaced apart along the extending direction of the base plate; The second positioning block has a second mating part formed on it, which corresponds to the third mounting part; The second positioning block is also provided with an arc-shaped groove, the center of which coincides with the center of the third mounting part.

[0015] Compared with the prior art, the present invention has the following advantages: The door and window mullion positioning ruler of the present invention has a top block set in the insertion space of the main body to fix the ruler between the top block and the main body, so as to facilitate the adjustment of the scale of the ruler according to the required position of the mullion. At the same time, a first positioning block is set at one end of the ruler to locate the position of the mullion, and a second positioning block is set on the main body to abut against the door and window frame profile, thereby fixing the positioning ruler and the starting point, so as to conveniently determine the position of the mullion.

[0016] Another objective of this invention is to provide a positioning method for a door and window mullion positioning ruler, using the door and window mullion positioning ruler as described above, the steps of which are as follows: Step S1: Prepare materials by processing and cutting the door and window frame profiles to the predetermined size and shape; Step S2: Calculate the distance L between the mullion position and the end of the door and window frame profile, and adjust the scale M according to the distance L; Step S3: Installation. Place the second positioning block against one end of the door and window frame profile, and the first positioning block against the mullion to fix the mullion in place.

[0017] Furthermore, step S3 includes the following steps; Step S31: Adjust the second positioning block to the first measurement mode or the second measurement mode; Step S32: Install the connecting code. When the second positioning block abuts against one end of the door and window frame profile, the position of the first positioning block is obtained according to the calculation. Move the connecting code to abut against the first positioning block and fix the connecting code with an electric drill. Step S33: Install the muzzle by plugging the muzzle into the connector.

[0018] The positioning method of the door and window mullion positioning ruler of the present invention involves directly abutting the main body against one end of the door and window frame profile. Before the door and window frame is installed, the mounting bracket of the mullion is fixed at a predetermined position on the door and window frame profile. Then, the mullion is connected to the door and window frame, and finally, they are installed together with the opening. The positioning ruler of the present invention is easy to adjust, eliminating the need for the marking and re-inspection processes in the prior art. Furthermore, its simple structure and ease of implementation improve the construction efficiency of mullion measurement and positioning.

[0019] When installing door and window frames, use one end of the door or window frame as a reference to adjust the fit between the door frame and the opening. This avoids the misalignment of the sealing strips that occurs in existing technologies, which can lead to misalignment, inability to overlap, or the door sash touching the sealing strip. This prevents the reduction of the overall air tightness, water tightness, and thermal insulation of the window. It also effectively ensures the accuracy of the connection position between the door and window frame and the mullion and the overall structure, improving the aesthetics. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention in light of the specific circumstances.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Example 1 This embodiment relates to a positioning ruler for a door / window stile 10. Overall, as shown... Figure 1 As shown, the positioning ruler includes a body 1 with an insertion space 103, a top block 2 inserted into the insertion space 103, and a scale 3 connected between the top block 2 and the inner wall of the body 1. One end of the scale 3 has a first positioning block 4, which is used to position the mullion. The body 1 has a second positioning block 5, which is used to abut against the door / window frame profile 6 to determine the starting point of the positioning ruler. The initial scale value of the scale 3 is equal to the length value of the body 1, and the initial scale of the scale 3 is located near the end of the first positioning block 4.

[0027] With the above configuration, the positioning ruler of the door and window mullion 10 in this embodiment has the top block 2 set in the insertion space 103 of the body 1 to fix the ruler 3 between the top block 2 and the body 1, so as to facilitate the adjustment of the scale of the ruler 3 according to the required position of the mullion 10. At the same time, a first positioning block 4 is set at one end of the ruler 3 to locate the position of the mullion, and a second positioning block 5 is set on the body 1 to abut against the door and window frame profile 6, thereby positioning the positioning ruler and fixing the starting point, so as to conveniently determine the position of the mullion.

[0028] Furthermore, the positioning ruler in this embodiment is easy to adjust. Because the initial scale value of the ruler 3 is equal to the length of the body 1, the extension length of the ruler 3 plus the length of the body 1 is the distance between the position of the mullion 10 and the end of the door / window frame. This shortens the length of the ruler 3, and the scale reading is set at one end close to the position of the mullion 10, making it convenient for construction personnel to check the reading. The positioning ruler in this embodiment eliminates the need for marking and re-inspection procedures in the prior art, and its simple structure and ease of implementation improve the construction efficiency of measuring and positioning the mullion 10.

[0029] Based on the above overall description, this embodiment presents an exemplary structure for the positioning ruler of the door and window mullion 10, such as... Figures 1 to 3 As shown, the body 1 of this embodiment is made of steel casting, which is simple to process. The top block 2 is inserted into the insertion space 103 inside the body 1, and the scale 3 is inserted between the body 1 and the top block 2 along the extension direction of the body 1.

[0030] As a preferred embodiment, such as Figures 1 to 4 As shown, the main body 1 includes a base plate 101 and an arc-shaped member 102 protruding to one side from the base plate 101. The arc-shaped member 102 and the base plate 101 form an insertion space 103. The base plate 101 is provided with a plurality of first mounting portions 1011, and the top block 2 is provided with a first mating portion 201 corresponding to the first mounting portions 1011. The top block 2 is fixed to the main body 1 by bolts.

[0031] Furthermore, such as Figures 2 to 3 As shown, the side of the base plate 101 facing away from the arched member 102 is also provided with a T-shaped protrusion 104. A groove 105 is formed between the protrusion 104 and the base plate 101. The groove 105 is used to insert into the rib 601 of the door and window frame profile 6. By providing the protrusion 104, it is easy to snap the body 1 onto the door and window frame profile 6, avoid the body 1 from swinging during measurement, and improve the stability of positioning measurement.

[0032] like Figures 1 to 4 As shown, a long strip support block 106 is also provided on the base plate 101, and the support block 106 is formed within the insertion space 103. A long groove 202 is formed on the top block 2, extending along its length, and the long groove 202 is adapted to abut against the upper part of the support block 106. The first mounting part 1011 penetrates through the base plate 101 and the support block 106. In this embodiment, the support block 106 is provided on the base plate 101 and is integrally formed with the base plate 101. The provision of the support block 106 not only increases the overall structural strength of the body 1, but also provides a support position for the top block 2.

[0033] To prevent scale 3 from wobbling during the stretching process, such as Figures 1 to 4As shown, the contact portion between the top block 2 and the scale 3 is shaped into a triangle, the longitudinal section of the scale 3 is shaped into a "V" shape, and the contact portion of the bow-shaped component 102 is adapted to the shape of the scale 3. This design ensures that the scale 3 remains in contact with the top block 2 and the bow-shaped component 102 throughout the dimensional adjustment process, effectively guaranteeing the positional accuracy of the scale 3 during movement, improving the positioning accuracy of the mullion 10, and reducing positioning deviation.

[0034] In order to fix the scale 3 in the insertion space 103, the base plate 101 of this embodiment is provided with a through first mounting part 1011. The first mounting part 1011 is formed into a round hole, which passes through the base plate 101 and the support block 106. The first mating part 201 is a threaded hole formed on the top block 2. The bolt is inserted into the first mating part 201 from the base plate 101 and tightened downwards to make the top block 2 close to the scale 3, so that the scale 3 is fixed. After fixing the scale 3, the positioning installation of the mullion 10 is carried out to ensure that the position of the mullion 10 does not move.

[0035] Preferably, such as Figures 1 to 4 As shown, a mounting plate 7 is provided at one end of the scale 3 near the first positioning block 4. The mounting plate 7 has a second mounting part 701, and the first positioning block 4 is fixed to the mounting plate 7 through the second mounting part 701. The first positioning block 4 also has two spaced-apart openings 401, which are symmetrically formed on both sides of the second mounting part 701. The mounting plate 7 has a pin 8 protruding outward, and the diameter of the pin 8 is adapted to the inner diameter of the opening 401.

[0036] In this embodiment, the first positioning block 4 is formed into a rectangular plate structure, the mounting plate 7 is a flat plate structure that seals one end of the scale 3, the second mounting part 701 is a threaded hole formed on the mounting plate 7, and the first positioning block 4 is provided with a through hole. The first positioning block 4 is fixed to the mounting plate 7 by bolts. In addition, two opposing opening slots 401 are provided on the first positioning block 4. When adjusting the positioning of the body 1 and the door and window frame profile 6 at different ends, the first positioning block 4 can overlap on the door and window frame profile 6 without interference.

[0037] As a preferred embodiment, such as Figures 5 to 7 As shown, the second positioning block 5 is shaped into a triangle. One corner of the second positioning block 5 is provided with an abutment surface 501. The second positioning block 5 is detachably connected to the base plate 101. When the abutment surface 501 abuts against the side of the protrusion 104, the positioning ruler is in the first measuring form. Right angle surfaces 502 are connected to both sides of the abutment surface 501. When any right angle surface 502 abuts against the side of the protrusion 104, the positioning ruler is in the second measuring form.

[0038] The first measurement method is for measuring and positioning the door and window frame profile 6 when it is cut at a 45° angle, which is commonly used in construction. The second measurement method is for measuring and positioning the door and window frame profile 6 at a 90° angle. As... Figure 5 and Figure 7 As shown, by adjusting the angle of the second positioning block 5 relative to the body 1, the positioning requirements for processing different door and window frame profiles 6 can be met, thereby improving the applicability and flexibility of the positioning ruler.

[0039] More specifically, such as Figures 2 to 3 As shown, the base plate 101 is provided with a third mounting portion 107 and a fourth mounting portion 108 spaced apart along the extending direction of the base plate 101. The second positioning block 5 is formed with a second mating portion 503 corresponding to the third mounting portion 107. The second positioning block 5 is also provided with an arc-shaped groove 504, the center of which coincides with the center of the third mounting portion 107. The third mounting portion 107 also uses a threaded hole, and the second mating portion 503 is a circular through hole. The second positioning block 5 is fixed to the base plate 101 by bolts.

[0040] When the angle of the second positioning block 5 needs to be adjusted, loosen the aforementioned bolts, adjust the angle of the second positioning block 5, and tighten the bolts after the angle is adjusted to the correct position. Furthermore, to further increase the fixing stability of the second positioning block 5, the fourth mounting part 108 uses a threaded hole located on one side of the third mounting part 107 and corresponding to the arc-shaped groove 504. Another bolt passes through the arc-shaped groove 504 and is inserted into the fourth mounting part 108, effectively ensuring the fixing effect of the second positioning block 5 and preventing rotation or movement during measurement.

[0041] Example 2 This embodiment relates to a positioning method for a positioning ruler for a door / window mullion 10, such as... Figures 5 to 7 As shown, this positioning method uses the door and window mullion 10 positioning ruler described in Embodiment 1, and its steps are as follows: Step S1: Prepare materials, and process and cut the door and window frame profiles 6 to the predetermined size and shape; Step S2: Calculate the distance L between the position of the mullion 10 and the end of the door and window frame profile 6, and adjust the scale M of the ruler 3 according to the distance L; Step S3: Installation. The second positioning block 5 is abutted against one end of the door and window frame profile 6, and the first positioning block 4 is abutted against the mullion 10 to fix the mullion 10 in place.

[0042] In a preferred embodiment, step S3 described above includes the following steps; Step S31: Adjust the second positioning block 5 to the first measurement configuration or the second measurement configuration; Step S32, install the connecting code 9. When the second positioning block 5 abuts against one end of the door and window frame profile 6, the position of the first positioning block 4 is obtained according to the calculation. Move the connecting code 9 to abut against the first positioning block 4 and fix the connecting code 9 with a hand drill. When installing connector 9, the position and dimensions of the connector need to be recalculated, and the position of scale 3 needs to be adjusted before installation.

[0043] Step S33: Install the muzzle 10 by plugging the muzzle 10 into the connector 9.

[0044] The positioning method of the door and window mullion 10 positioning ruler in this embodiment involves directly abutting the body 1 against one end of the door and window frame profile 6. Before the door and window frame is installed, the mounting bracket of the mullion 10 is fixed at a predetermined position on the door and window frame profile 6. Then, the mullion 10 is connected to the door and window frame, and finally, they are installed together with the opening. When installing the door and window frame, the fit between the door frame and the opening is adjusted based on one end of the door and window frame. This avoids the overlapping and misalignment of the sealing strip in the prior art, which can lead to misalignment or the door sash touching the sealing strip, reducing the air tightness, water tightness, and heat insulation of the entire window. It also effectively ensures the connection position accuracy between the door and window frame and the mullion and the overall structure, improving the aesthetics.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
