Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a groove frame fitting joint for securing a film or sheet stretched on a simple house such as a vinyl house, and in particular, to a joint for attaching a groove frame to a simple house such as a vinyl house. The present invention relates to a practical joint equipped with a locking mechanism that can be received in a fitted manner and firmly grip the frame.

[Conventional technology]

Conventionally, the groove frame of the stopper that locks the vinyl sheet is either directly attached to the house structural aggregate with screws, bolts, nuts, etc., or it is a specially structured groove frame that is attached to the C-shaped structural member, for example. It is indirectly attached by a stop panel member. This member consists of a groove frame receiving panel section consisting of a receiving panel section and a caulking panel section, and a tongue-shaped panel section fixed to a C-shaped structural member.
It is formed integrally with a guide panel interposed therebetween, and a guide panel is also integrally formed on the other side of the receiving panel part. In the former case, it is difficult to attach and remove the groove frame, and the frame itself has many holes for attaching screws, etc., so that it cannot be expected to be used for a long period of time. In addition, the latter mounting panel member has a complicated structure, and its manufacturing is not only industrially disadvantageous, but also the locking of the groove frame to be inserted is determined by the crimping angle of the crimping panel, etc. Therefore, if the degree of fixation of the frame is increased, the fitting will become tighter and the operability will be lowered.On the other hand, if the fitting is made easier, the frame will easily come off, and therefore, the fixing property will be deteriorated.

[Problem that the invention attempts to solve]

An object of the present invention is to provide a joint that has a simple structure, is easy to attach to structural aggregates, and is easy to attach and detach from a groove frame. Another object of the present invention is to provide a joint for a film retaining groove frame which has excellent locking and fixing properties and can firmly grip the fitted groove frame.

[Means for solving problems]

In order to solve the above-mentioned problems, the inventor of the present invention has conducted numerous trial production studies and has developed a practically desirable groove frame fixing joint that can effectively achieve the above-mentioned objectives.

That is, in the present invention, a joint for connecting dovetail-shaped frames has two or more dovetail-shaped rising portions that receive both edges of the dovetail-shaped rising edges of the frames, and the bottom plate portion thereof has two or more dovetail-shaped rising portions that receive the rising edges of the dovetail-shaped frames. Two parallel cuts are formed that coincide with the insertion direction, and the long sides formed by the cuts and the short sides integral with the bottom plate connecting the opposite ends of the long sides are formed. A fixed spring member having a convex curved surface that protrudes from the inner surface of the bottom plate toward the insertion side of the groove frame. The present invention provides a dovetail-shaped frame connection joint.

The joint of the present invention is a groove frame joint suitable for joining film retaining groove frames in an extended shape or in a cross shape such as a T-shape or a cross shape. It is characterized in that it is formed into a shape that can be received, and that two or three groove frame fixing spring members are integrally formed using a part of the bottom plate. Therefore, this fixed spring member can be easily formed by pressing the bottom plate part of the joint, and is formed by cutting both long sides of a long strip-like part, and by cutting the bottom plate part of the joint by cutting both long sides. The curved portion is made to protrude toward the insertion side of the groove frame to form a convex curved surface.

[Effect]

In the metal joint of the present invention, the fixed spring member is a protruding curved surface spring that utilizes metal rigidity, so the sliding resistance of the film locking groove frame is relatively small, and therefore the groove frame is easily inserted. On the other hand, the inserted groove frame is strongly pressed and fixed by the receiving groove of the joint and the spring member, so it is extremely difficult to use in practice.
A desirable fixture.

〔Example〕

Next, the present invention will be explained in more detail with reference to the accompanying drawings.

Fig. 1 is a perspective view of an example of the joint of the present invention, showing a state in which only one groove frame is fitted in an extended manner in the same direction, and the state in which the fitting is completed is shown by imaginary lines. There is.

FIG. 2 is a perspective view showing an example of a T-shaped joint (Figure a) and a cross-shaped joint (Figure b).
The film locking groove frame 1 is generally well known as a member for locking and tensioning the film of a simple house in combination with a film locking member (not shown) such as a meandering metal wire. It is something that

The joint shown in FIG. 1 has the simplest structure for joining and connecting the film retaining groove frames 1 in a straight line, and has both raised edges 2, 2 forming the receiving groove of the groove frame 1. It has rising portions 3, 3 on both edges in the length direction for receiving, and rectangular fixed spring members 4, 4 are formed on the bottom plate portion. This elongated fixed spring member is formed by having long sides 5, 5 cut into the bottom plate part so as to match the insertion direction of the frame 1, and other short sides 6, 6 which are not cut. The rectangular bottom plate portion is formed into a convex curved surface by slightly protruding toward the receiving groove side, that is, toward the upper side. In addition, in the case of this linear joint, in order to determine the position of the joint ends of the two groove frames, each rising portion 3 has inwardly convex facing protrusions 7, 7.
is attached. Since this joint receives and grips the ends of the groove frame, it can be extremely short and small, making it easy to handle and attaching to the structural aggregate, for example, at both ends of the bottom plate. It can be easily and firmly attached to the provided through holes 8, 8 with screws, bolts, nuts (not shown), etc. The end of the joint is
To make it easier to insert the groove frame, the rising part is often expanded slightly outward to form an opening.
The groove frame to be inserted is inserted while being restrained by the rising part, but the bottom surface of the bottom plate of the frame is
The joint presses against the protruding curved surface of the fixed spring member and slides smoothly to the specified position.
You can easily install the groove frame. Since the attached groove frame does not substantially come off due to the pressing frictional resistance of the fixed spring member 4,
Suitable as a joint for simple houses that are easily affected by wind.

Figure a in Figure 2 is a perspective view of an example of a T-shaped joint, and one longitudinal end of the joint has a receiving groove for fitting the first groove frame in the longitudinal direction. At the other end, a receiving groove into which a second groove frame is inserted is formed in a direction perpendicular to this by rising members 3', 3'.

In addition, Figure b is a perspective view of a joint for linearly connecting two groove frames and cross-connecting another groove frame in a cross shape on the same plane, from both ends in the length direction. The groove frames are fitted into each frame, and a third frame is fitted into the center part in a crosswise manner.

[Effect of idea]

The width of the joint of this invention is, for example, 2.5 to 4.
It is a small member with a length of about 10 to 20 cm, and is extremely easy to manufacture and install.The installation operation of the groove frame is also simple, and its practical value as a joint for the film retaining groove frame of a simple house is expensive.
