Description

[Detailed Description of the Invention] This invention relates to a bearing member for a pinion or a pinion shaft in a pinion rack type ventilation window opening/closing device.

The purpose of this invention was to improve the straightness of the pinion shaft, which is installed over the entire length of the long ventilation window of the greenhouse.
It has enough flexibility to absorb deformation, construction error, installation error, misalignment, etc. of the greenhouse frame material to which the supporting bearing member is attached, without impairing the rotational operability of the pinion, and by extension, the ventilation window. It is an object of the present invention to provide a bearing member for a pinion rack type ventilation window opening/closing device that has an improved structure that does not impair opening/closing operability.

That is, as a prior art, the bearing member described in Japanese Utility Model Application Publication No. 55-85477 has a structure in which a mounting seat for attaching and fixing it to the frame of a greenhouse is integrally provided, so when this is attached to the frame at once, Deformation of the frame material, construction errors, installation errors, etc. directly affect the support state of the pinion or pinion shaft. On the other hand, the pinion shaft maintains its straightness regardless of the deformation of the greenhouse frame. Therefore, the deterioration of the support state by the bearing member causes creaking or wobbling of the pinion shaft rotation, resulting in excessive rotational resistance, making the rotation operation extremely difficult or impossible, and eventually making it difficult or impossible to open and close the ventilation window. However, there are drawbacks that make it difficult to put it into practice.

This invention overcomes the above-mentioned drawbacks of the prior art.
This was done for the purpose of solving a problem.

To summarize this idea, it consists of a fixed member that is attached and fixed to the framework of the greenhouse, and a movable support member that is swingably connected to the fixed member.The movable support member fits into the boss of the pinion and is rotatable. It has a substantially U-shaped notch-shaped bearing part that can be supported, and has a restraining guide part that comes into sliding contact with both side parts of the pinion and the fan-shaped rack that engages with the pinion and restrains the relationship between them, and has an inner diameter surface part of the fan-shaped rack. A bearing member for a pinion rack type ventilation window opening/closing device, characterized in that the bearing member has a guide roller that comes into contact with the pinion rack type ventilation window opening/closing device.

Next, this invention will be explained with reference to illustrated embodiments.

FIG. 1 shows an exploded configuration of the bearing member according to this invention, and FIG. 2 shows its assembled state of use.

In the figure, 1 is a fixed member, 2 is a movable support member that is swingably connected to the fixed member 1 by a connecting bolt 3 and a nut 4, and these constitute a bearing member.

The fixing member 1 is attached and fixed to the sheet stopper frame 5, which is the frame material of the greenhouse, and is made by bending a plate material into a substantially symmetrical shape, and has an upper surface portion 1b.
In order to pass through the lip gap 5a of the seat stopper frame 5 and hang onto the lips 5b, a pair of latching pieces 1a, which are symmetrical and have an inverted L shape, are placed back to back.
1a is stamped and molded. 1 pair of latching pieces 1
The actual distance a and the width b of the lip gap 5a are smaller than the width c of the lip gap 5a. Also, the actual height h is
The height is equal to or slightly larger than that of the lip 5b. Therefore, the fixing member 1 has its pair of latching pieces 1a, 1a in the longitudinal direction separated by the lip gap 5a.
Insert it so that it matches the longitudinal direction of the upper surface part 1b.
is in contact with the bottom surface of the seat stopper frame 5, and when turned approximately 90 degrees, the pair of latching pieces 1a, 1
a becomes stuck on the lips 5b and cannot be removed. The fixing member 1 has a raised piece 1c raised from one side surface so as to form a common plane with the upper surface part 1b, and the raised piece 1c has a U-shaped notch-shaped bolt insertion groove 1d. It is formed. Uchihata piece 1
The width e of the lip gap 5a is sufficiently larger than the width c of the lip gap 5a.

The head piece 7 of the T-bolt 6 that passes through the bolt insertion groove 1d has a width i smaller than the width c of the lip gap 5a, and a length j slightly larger than the inner dimension between both side walls of the seat fastener frame 5. It is said to have a large composition. 7a is a bent portion for preventing rotation.

Therefore, as mentioned above, the pair of latching pieces 1a, 1a
The T-bolt 6 is attached to the fixing member 1 which is hooked onto the lips 5b, 5b, and the head piece 7 is inserted into the lip gap 5.
Insert it so that it aligns with the longitudinal direction of a, and then move it laterally to insert it into the bolt insertion groove 1d of the raised piece 1c.
Insert it inside and turn it about 90 degrees to remove lip 5b,
5b, and then screw in and tighten the nut 8. Then, the T-bolt 6 is prevented from rotating together by the head piece 7, making it easy to tighten the nut 8, and also firmly immobilizes the fixing member 1 as a joint action with the latching pieces 1a, 1a. can be fixed in this state. In the figure, 1f and 1f are bolt holes provided at the lower part of the fixing member 1 for insertion of connecting bolts.

Next, the movable support member 2 is also made up of two parallel plate parts 2c, 2c, which are made by bending a plate material into a substantially symmetrical shape at the connecting part 2b, and in particular the inner width dimension m of the fixed member 1 is On the other hand, the movable support member 2 is formed so that the outer width dimension n of the plate-shaped portions 2c, 2c is the same or slightly smaller. The movable support member 2 has bolt holes 2a, 2a at its upper end, through which the connection bolts 3 are passed. Therefore, the movable support member 2 can be moved by inserting its upper end into the lower part of the fixed member 1, aligning the centers of each bolt hole 2a and 1f, and passing the connecting bolt 3 through. They can be swingably connected.

The movable support member 2 has a U-shape in which the boss portion 9a of the pinion 9 can be fitted in the lateral direction (horizontal direction in FIG. 2) and rotatably supported approximately at the center of the plate-like portions 2c, 2c. Notch-shaped bearing portion 2d
has. 2d' is a flange portion which is bent to expand the bearing area of the bearing portion 2d. Bearing part 2
The opening width l of d is formed to be approximately equal to the diameter of the boss portion 9a of the pinion 9. The tooth width of the pinion 9 is configured to be approximately equal to the inner dimension of the plate-like portions 2c, 2c, and the plate-like portions 2c, 2 are provided on both side surfaces of the pinion 9.
The inner surface of c is configured to slide into contact with each other and serve as a restraining portion to prevent lateral displacement. Furthermore, the fan-shaped rack 10 that engages with the pinion 9 has a thickness (dimension in the direction perpendicular to the plane of the paper in FIG. 2) that is approximately equal to the inner dimension of the plate-shaped portions 2c, 2c, and has a thickness that is approximately equal to the inner dimension of the plate-shaped portions 2c, 2c. The inner surfaces of the plate-shaped parts 2c, 2c are configured to slide into contact with each other and serve as a restraining part to prevent lateral displacement thereof. In other words, the inner surfaces of the plate-shaped parts 2c, 2c are restraining guide parts that come into sliding contact with both side surfaces of the pinion 9 and the fan-shaped rack 10 that meshes with the pinion 9, thereby restraining the relationship between them.

Next, reference numerals 11 and 11 in the figure are guide rollers that are detachably installed with bolts 12 and nuts 13 above and below the entrance end of the bearing portion 2d of the movable support member 2. This guide roller 11 contacts the inner diameter surface portion 10a of the fan-shaped rack 10 and guides its movement (rotation), and also serves to guide the movement (rotation) of the fan-shaped rack 10.
Constrains the meshing relationship with 0. Fan-shaped rack 10
The upper end of the greenhouse is connected to the window frame of the ventilation window of the greenhouse.

Next, the usage and operation of the bearing member having the above structure will be explained.

In the first step of the method of use, the pinion 9 and the fan-shaped rack 1 are attached to the lower surface of the sheet stopper frame 5 fixed on the pipe 14 which is the frame material of the greenhouse.
0, the fixing member 1, its latching pieces 1a, 1a are latched onto the lips 5b, 5b of the seat stopper frame 5, and the T-bolts 6 and nuts 8 are used to drive the fixing member 1, and the pieces 1c are fixed. Attach and secure firmly. Next, insert the upper end of the movable support member 2 into the lower part of the fixed member 1, and
By aligning the centers of f and 2a, and passing the connecting bolt 3 through and screwing in the nut 4, they are swingably connected. Thereafter, the pinion shaft 15 is lifted, and the boss portion 9a of the pinion 9 is fitted into the bearing portion 2d of the movable support member 2 and supported. The pinion 9 is brought into engagement with the fan-shaped rack 10, and the movable support member 2 engages the fan-shaped rack 1 with its plate portions 2c, 2c.
The guide rollers 11, 11 are placed above and below the inlet end of the bearing portion 2d with the bolts 12,
Installed with nut 13, same guide rollers 11,1
1 is brought into contact with the inner diameter surface portion 10a of the fan-shaped rack 10, and the assembly is completed.

In such a case, the plate-shaped portion 2c of the movable support member 2,
2c, the bearing portion 2d, and the guide roller 11, the meshing relationship between the pinion 9 and the fan-shaped rack 10 is well restrained to a constant state, and the rotation of the pinion 9,
The movement of the fan-shaped rack 10 is well guided. In this way, the interlocking relationship is constrained to a constant state, but if the sheet stopper frame 5 or the pipe 14, which is the framework of the greenhouse, is deformed or otherwise,
The fixed member 1 and the movable support member 2 are freely absorbed by rotating (swinging) around the connecting bolt 3,
A good meshing state between the pinion 9 and the fan-shaped rack 10 is always maintained.

Next, FIG. 3 shows a different example of the structure of the fixing member. That is, this fixing member 1' is made by bending a plate material into a substantially symmetrical shape with an outer dimension b' that is smaller than the width c of the lip gap 5a of the sheet fastener frame 5, and has a moderate length from its upper surface 1b'. A notch 1a'' with a parallel gap h' that is equal to or slightly larger than the height of the lip 5b is formed symmetrically in the lower part by the dimension, and a notch 1a'' with a width smaller than the width c of the lip gap 5a is formed in the center of the notch 1a''.
A neck portion 1a of a' is formed. Then, a U-shaped notch-shaped bolt insertion groove 1 is formed in a raised piece 1c' which is raised from one side surface at the same level as the lower edge of the notch 1a''.
d' and further provided with bolt holes 1f' and 1f' in the lower part.

When this fixing member 1' is used, it is inserted with the longitudinal direction of its upper surface portion 1b' aligned with the longitudinal direction of the lip gap 5, so that the upper edge of the notch 1a'' reaches above the lips 5b, 5b. The method of use and operation and effect are almost the same as those of the first embodiment, except for the difference in that it is turned about 90 degrees in the hanging state and hooked onto the lips 5b, 5b.

Next, the effects of this invention will be explained. The bearing member of this invention consists of a fixed member that is attached and fixed to the framework of the greenhouse, and a movable support member that is swingably connected to the fixed member. A restraining guide part that has a substantially U-shaped notch-shaped bearing part that can be supported, and that slides into contact with both side parts of the pinion and the fan-shaped rack that engages with the pinion to restrain the relationship between them, and an inner diameter part of the fan-shaped rack. Since the structure includes the guide rollers that come into contact with each other, there is flexibility in rotatably supporting the pinion or the pinion shaft, and a good meshing state between the pinion and the fan-shaped rack can be maintained at all times. Therefore, if the frame of the greenhouse is deformed or there is an error in the construction due to long-term use, or if there is an error in the installation of the ventilation window opening/closing device, the rotation operation of the pinion or pinion shaft should be avoided. This does not impair the functionality of the ventilation window, nor does it impair the operability of opening and closing the ventilation window, making it particularly effective as a long ventilation window.
