Description

[Detailed description of the invention] The present invention provides a fixing device for the inner window frame of an elevating window, in particular, a pair of engagement rods are slidably penetrated in the longitudinal direction of the horizontal frame of the window inner frame, and A finger rest is fixedly provided on the part, and the finger rest is equipped with an operator corresponding to the part so that it can be raised and lowered. The present invention relates to a window inner frame fixing device in which the outer end portion of each engaging rod is engaged with and disengaged from a side portion of the window inner frame into a recessed hole on the window outer frame side.

There is a conventional device of this type disclosed in Utility Model Application Publication No. 10853 of 1929, which uses a pair of forward and backward movements to control the vertical movement of a sliding plate (corresponding to the operator of the present invention). A link mechanism including a moving plate and connecting rods connected to both ends of the moving plate is used to convert the horizontal movement of the rod (engaging rod).

According to this link mechanism, by pressing down the sliding plate through the indenter, the shaft rod presses the body plate through the body plate supporter, and thereby the inner end portion is connected to this shaft rod. The moving plate tilts downward from its outer end to its inner end, and is drawn inward by the continuous rods while lowering itself, while each advancing and retracting rod is pulled in the backward direction by the continuous rods. However, according to such a link mechanism, the amount of movement of the advancing and retracting rod is very small compared to the amount of descent of the sliding plate, and a considerable pressing force is required to press down the sliding plate. In addition, such a link mechanism has the disadvantage that the number of parts increases and the structure becomes complicated.

The purpose of this invention is to eliminate the above-mentioned drawbacks of conventional devices, and to provide a window frame fixing device using a bell crank instead of the above-mentioned conventional link mechanism. To do this, a pair of bell cranks are placed on both sides of the operating element, one end of each bell crank is pivotally connected to the operating element, and the other end is pivotally connected to the inner end of each engagement rod. A spring member is interposed in the bell crank to constantly bias the operating element to the ascending position and each engagement rod to the engagement position of pushing into the recessed hole on the window outer frame side. By lowering the bell crank against the member, each bell crank is rotated, and the outer end of each engaging rod is caused to escape from the recessed hole on the window outer frame side.

Hereinafter, one embodiment of the present invention will be described based on the drawings.In the metal fitting 3, the vertical wall 2 is mounted upwardly from one side edge of the horizontal wall 1. A hanging wall portion 4 is provided that projects further upward from the center portion of the portion 2, and a pair of tongue-shaped gripping pieces 5, 5 are formed from both side edges of the hanging wall portion 4 in parallel to the front surface of the hanging wall portion 4. The plate-like operator 6 is attached to the hanging wall portion 4 and is inserted between the gripping pieces 5, 5 and the hanging wall portion 4 from above.

Further, a vertical guide elongated hole 7 is provided from the hanging wall portion 4 to the vertical wall portion 2, and the guide elongated hole 7 and the operator 6
A guide pin 8 is fitted in both, so that the operator 6 can be moved up and down using the engagement between the guide elongated hole 7 and the guide pin 8.

Reference numeral 9 denotes a finger rest projecting outward from the upper end of the operator 6.

Reference numeral 10 denotes an upper horizontal wall portion extending from the hanging wall portion 4 parallel to and opposite to the horizontal wall portion 1, and screw holes 11 and 12 are provided in both the horizontal wall portions 1 and 10.

These screw holes 11 and 12 are used to fix the bell crank fitting 3 to the window inner frame 13.

In the bell crank installation described above, the bell cranks 14 and 15 are arranged inside the metal fitting 3 at both end positions sandwiching the hanging wall part 4, and each corner part of these bell cranks 14 and 15 protrudes from the vertical wall part 2. The bell cranks 14, 15 are pivotally connected to the provided pins 16, 16 so as to be movable up and down, and with the respective one ends of the bell cranks 14, 15 overlapping each other, an elongated pin insertion hole 17. 17 is opened, the guide pin 8 described above is inserted into these pin insertion holes 17, 17, and as the operator 6 is pushed down, the bell crank 14.15 moves to the pin 16.16.
It is configured to rotate following the surroundings.

18.18 is a helical spring fitted onto each pin 16.16, and the end of this spring member is brought into contact with the step 19 formed by bending the bell crank 14.15 and the side wall 1. A spring force is applied to the bell cranks 14, 15 in the direction of pressing the operator 6 upward.

33.33 is a part of the stopper that the bell crank 14.15 comes into contact with due to the biasing force of the helical springs 18, 18, and these stopper parts 33.33 extend in the lateral direction from the upper edge of both ends of the vertical wall part 2. It is formed to extend.

20. Denoted at 20 is a snap ring fitted onto the pins 16 and 16 to prevent the helical springs 18, 18 from coming off.

Also, at the other end of each bell crank 14, 15 is a pivot pin 2.
Metal fittings 22 and 22 are attached to the engagement rod through 1° 21.

When attaching the fixing device constructed in this manner to the window inner frame 13, an opening 24 having a horizontal length comparable to the entire length of the fitting is formed in the center of the lower stile 23 of the window inner frame 13 in the elevating window of the structure shown in FIG. The bell crank mounting fittings 3 are housed inside the lower stile 23 through this opening 24,
In this storage position, the screw holes 11.1 in the side walls 1, 10
The metal fitting 3 is fixed to the lower stile 23 by screwing screws 25 and 25 from the lower stile 23 to the bell crank 2.

In addition, in this storage position, only the operator 6 protrudes outside the lower stile 23.

In this bell crank installation, the engagement rods 26, 26 are inserted into the lower stile 23 so as to be able to slide laterally at the left and right positions of the metal fittings 3, and the inner ends of the engagement rods 26, 26 are inserted into the lower stile 23 at the left and right positions thereof. The mating rods are attached to metal fittings 22 and 22 with nuts 27 and 27, respectively, and the opening 24 is closed by a lid 28.

This closure is accomplished by screwing screws 29 and 29 passed through the left and right positions of the lid body 28 into screw holes 30 and 30 formed at both ends of the vertical wall portion 2.

Further, the upper edge of the lid body 28 extends outwardly opposite to the finger rest portion 9, thereby forming a finger rest portion 31.

Therefore, the bell crank 14.15 has a helical spring 18
．． The operating element 6 is always kept in an upwardly biased position with a force of 18, and in this position, the outer ends of the engagement rods 26, 26 are projected to both sides of the window inner frame 13, and the window outer frame 32 recessed hole 33
The inner window frame 13 is thereby fixed.

Next, in order to raise and lower the window frame 13, the finger hooks are operated by hooking the fingers on the parts 9 and 31 and pulling them together. The cranks 14 and 15 rotate around the pins 16 and 16, and the engagement rods 26 and 26 are pulled together.
6 exits from the recessed hole 33, so that the inner window frame 1
3 is released and the window inner frame 13 can be raised and lowered in any direction by human power, and at the desired height position after lifting and lowering, the finger hook releases the force acting on the parts 9 and 31. Then, the outer ends of the engaging rods 26, 26 again enter the corresponding recessed holes 33 at their height positions, and the window inner frame 13 is fixed.

As explained above, the guide frame fixing device of the present invention has a pair of bell cranks arranged on both sides of the operator, one end of each bell crank is overlapped with each other, and a long hole is provided in the overlapped end. The overlapping end is connected to the operator through this elongated hole.
In addition, the other end of each bell crank is pivotally connected to the inner end of each engaging rod, and a spring member is interposed in each bell crank, so that the operator can be placed in the ascending position, and each engaging rod can be moved through the window. It is designed to be constantly biased at the engagement position where it enters the concave hole on the outer frame side, and a bell crank is used as the interlocking means between the operator and the engagement rod instead of using a conventional link mechanism. Therefore, unless there is an extremely large difference in the length of the two arms of the bellcrank, in other words, if it is a normal bellcrank, there will be a steaming difference between the amount of descent of the operator and the amount of movement of the engaging rod. In addition, it is possible to give the engagement rod a movement amount equal to or greater than the amount of descent of the operation element.Moreover, the bell crank makes it possible to utilize the lever action, and therefore, the operation element is relatively lowered. The engagement rod can be moved by a sufficient amount with a small amount of descent and a small pressing force, so that the operation of releasing the fixation of the window inner frame becomes very simple and easy.

In addition, in the device of this invention, whereas the link mechanism in conventional devices consists of multiple parts, the bell crank that corresponds to this link mechanism is a single item, so installation is easy and the space required for installation is simple. Therefore, it is possible to make the device more compact, and to provide a device that is structurally solid and has good durability.
