[Commercial Use]

In the present invention, the refraction from the outer part from the connection part of the meatlet of the mother's flesh, which occurs when the mass production of the mass of the fish is in contact with the ground, the bottom, the tree, the dry matter, etc. from the tip of the mother's tip. The present invention relates to an anti-reflection device for mass production that prevents (bending, bending, bending, warping, etc.).

[Prior art]

The mass production is made of eight end meats, one end of which is conically joined to the upper end cap fixed to the upper part of the mass production stand, and the other end is conically joined to the sum end cap that is freely fitted to the mass production stand. It is connected to the middle part of the mother's flesh, and it consists of eight bases which support each mother flesh below.

Both the carcass and the underarm are made of metal.

In general, as shown in FIG. 9, the connection between the mother flesh and the buttocks is made by inserting a metal connector B into the U-shaped groove of the middle portion (slightly near the mass production stand) of the mother flesh A. It is performed by conical joining the tip of the base to the connecting projection B2 of B). That is, the connection port B has a pair of connecting projections B2 protrudingly formed at opposite intervals at predetermined intervals in the middle portion of the relatively short rectangular pieces B1 curved in a U-shape, and each piece B1. The outer side portions of both sides of the connecting projection B2 of () are fixed by the mother meat (A) and the cocking (C).

Then, a pair of connecting projections (B2) are opened in the boreholes, and the ends of the receiving ribs are inserted between the pair of connecting projections (B2), and the ends of the receiving ribs are attached to the pair of connecting projections (B2). To conical joints.

When unfolding the mass production, the lower end cap is raised along the mass production stand, and the position of the base for stopping the lower end cap is fixed by the upper spring, and the mother meat is supported by the base from the bottom to maintain the unfolded state. In this state, when external force is applied from the tip (tip body side) to the root (mass production side) with respect to the mother meat, the meat is fixed so that the meat acts to press the mother meat outward through the connecting part. Therefore, the external force (impact) applied from the tip side of the mother's flesh concentrates on the connection part of the mother's butt. The mother flesh is bent downward by the tension of the mass production spring attached to the outer surface, and the tip body of the mother flesh tip is preferably in the direction pointing to the ground.

[Problems that the invention tries to solve]

Therefore, in mass production, if the tip body part of the tip ends contact with the ground or the floor or is inadvertently touched with wood or dry goods by blowing or throwing the wind in an unfolded state, the impact force is Concentrates on the joint with the undercarriage and causes an uncomfortable situation in which the horseshoe bends (bents, bends, bends, twists, etc.) at the location of the tip or the outer side of the tip body of each piece B1 of the short connection port. .

Therefore, an object of the present invention is to prevent the refraction of the mother's flesh accurately and to increase the durability of the mass production, which may occur when the mass production in the open state is impacted from the tip body side.

[Means for solving the problem]

In order to achieve the above object, the present invention is to insert a reinforcing member for connecting the buttocks and reinforcing the killing in a state of densely filling the internal space in the U-shaped groove in the connecting portion with the support for the killing. The member integrally forms a connecting projection with the base meat on a rod of a desired length in which fibers such as glass fiber, carbonate fiber, and fluorine fiber are formed of reinforcement resin, and further expands the swelling portion along the longitudinal direction on the outer surface of the rod. It is protruding, and the desired length of the rod-like body in the reinforcing member is longer than that of the conventional connection port for connecting the butt, ie, when the mass is impacted from the tip body side, it concentrates on the connection point with the butt of the mother meat. Characterized in that the impact force is set to a length sufficient to be as small as possible at the tip of the rod-shaped body.

[Action]

Concentrating on the connection point with the buttocks of the carcasses in the U-groove in the U-groove in the U-groove, compared to the conventional butts for connecting the meatlets, that is, when the mass is impacted from the tip body side. The rod-shaped body is sandwiched in a reinforcing member whose length is sufficient so that the impact force to be made is as small as possible at the tip end of the rod-shaped body, and the rod-shaped body densely fills the inner space in the U-shaped groove of the mother flesh. At the same time, the fiber is made of reinforcing resin, and has the appropriate hardness and elasticity.

Therefore, when the mass is impacted from the tip body side, the structural and impact force of the mass is concentrated on the connection point between the mother and the buttocks, but this excessive impact force is more noticeable than the conventional one. Is making it smaller.

That is, in the related art, the butt joint B is short and is not filled with a space portion in the U-shaped groove of the mother flesh with the same cross-sectional U-shaped thin metal piece, and the absorbency of the impact force and the underlay are not sufficient. The excessive sorting force concentrated at the connection point with the gland acts on the mother-to-arm as approximately the same pressure at the tip body side end portion of the connection port B as well as the connection point between the mother and the buttocks. Therefore, in the related art, the tip body side end portion of the connection port B, in which excessive impact force acts as approximately as it is, becomes a resistance, and the mother-to-eye easily bends and bends at the position of the portion.

On the other hand, in the present invention, the rod-shaped body of the reinforcing member is fitted in a state of densely filling the space in the U-shaped groove of the mother flesh, and the rod-shaped body of the mother flesh and the reinforcing member is integrated and the absorbency of impact force in relation to the material is absorbed. Not only is it abundant, but the length of the rod-shaped body of the reinforcing member is set to a predetermined length longer than that of the conventional connection port B as described above. Since it is located far from the center, even if excessive impact force is concentrated in the connection point between the mother and the undercarriage, the impact force is sufficiently absorbed and alleviated, and the pressure of the impact force acting on the distal end portion near the tip of the rod body is known. It is much smaller compared to the conventional ones, and therefore, unlike the related art, the endings of the rods near the tip of the rod body may easily be broken and bent. There is no.

EXAMPLE

Another embodiment of the present invention will be described with reference to FIGS. 1 to 8.

Reference numeral 1 denotes a metal mother-shaped flesh having a U-shaped cross section, and the reinforcing member 2 is inserted into the connecting portion of the mother flesh and the U-shaped groove of the periphery thereof as shown in FIGS. 1 to 3. The reinforcing member 2 is a connection projection 2b with the receiving meat 3 near one end of the rod-shaped body 2a of the desired length, in which fibers such as glass fibers, carbonic fibers, and fluorine fibers are formed of reinforcing resin. ) Is integrally formed, and the outer surface of the rod-like body 2a protrudes from the bulging portions 2c and 2d along the longitudinal direction. The claw hole 2e is opened in the connecting projection 2b.

As described above, the reinforcing member 2 is mounted in the U-shaped groove of the mother meat 1 over the connection point with the buttocks, but at the long side with respect to the connecting projection 2b of the rod 2a. The part is arranged along the tip of the mother meat 1 along the tip body side.

The cross-sectional shape of the rod-like body 2a of the reinforcing member 2 is suitable for densely filling the hollow portion in the U-shaped groove of the mother meat 1, as in the third diagram. In addition, the width of the connecting projection 2b is slightly wider than that of the rod-like body 2a, and when the reinforcing member 2 is fitted into the mother meat 1, both bottom surface portions of the connecting projection 2b are provided. Is placed on the upper surface of both sides of the U-groove of the mother flesh (1).

The fitting of the reinforcing member 2 in the mother flesh 1 is similar to that of the tip body side tip portion of the reinforcing member 2 and the two outer portions of the connecting projection 2b as shown in FIGS. 1 and 2. Both sides of the U-shaped grooves of the mother meat 1 are bent in the inward direction by bending caulking 3a, 3b, and 3c, whereby the mother meat 1 and the reinforcing member 2 are fixed. 2f is a notch groove provided in the rod-shaped body 2a in order to improve the followability of the reinforcing member 2 with respect to the deformation of the mother flesh 1, but this may not necessarily be provided.

One end of the undercarriage 4 is fixed to a two-part metal bracket 5, and a two-pronged portion of the connection bracket 5 is fitted to both outer surfaces of the connecting projection 2b to form a conical hole. By joining, rotation is possible with respect to the mother meat 1 of the base 4.

On the contrary, in the case where the connecting projection 2b is divided into two pieces and the conical joint is sandwiched between the ends of the connecting brackets flatly pressed between them or similarly, the connecting ends of the buttocks 4 flattened in between. have.

6 to 8 show another embodiment in which the shape of the reinforcing member 2 is slightly changed. FIG. 6 shows no bulging portion 2d with respect to the above embodiment, FIG. 7 shows notch grooves 2g and 2h in both outer portions of the connecting projection 2b, and FIG. 8 shows notch grooves. The bulging parts 2c and 2d are formed over the full length of the rod-shaped object 2a, without providing it at all.

[Effects of the Invention]

This invention consists of said structure, and has the following effects.

(1) In conventional mass production, a splice formed with a connecting projection with a butt in each piece of metal having a relatively short cross-sectional U-shape is fitted into a metal cross-shaped U-shape and the spout is conical. They are trying to connect the mother's flesh with the meat of the base.

Therefore, in the case of conventional mass production, if the ground, the bottom surface, the tree, the dry matter, etc. are contacted from the tip body side in the unfolded state by wind or carelessness, or try to maintain the unfolded state in the wind against the strong wind, Due to the lack of absorbency of impact force and the short length of the connector without the densely filling of its internal space in the same cross-sectional shape as the U-shaped groove of the mother, the impact force or pressure applied to the mother mass is The connection point with the butt where the caulking part increases the impact force on the joint which weakens the mother's flesh by concentrating with the press force in the butt which acts in the outward direction and concentrating on the connection with the butt. It is added that we are located in close distance, and tip of connection is among the connection point and the periphery part with mother's mouth The inconvenient situation that the bends in the region of the side occurred easily.

This strengthens the tension of the Yangsan stream on the rising side of the decorative effect and is particularly large for umbrellas whose tip body is more curved and the tip body points more in the ground direction. In the present invention, on the other hand, in the U-groove of the mother's flesh, the connection part with the buttocks and its surroundings are fitted with a reinforcing member made of a rod of a desired length in which fibers such as glass fibers are formed from a reinforced resin. .

This reinforcing member has a thin U-shaped cross-section and densely fills the space in the U-shaped groove of the mother meat that is easily refracted such as bending or bending deformation in the horizontal plane or vertical plane with respect to the longitudinal direction by external force. (Close fitting).

The rod body of the reinforcing member is not short as in the case of the conventional connector, but has a long desired length, that is, the impact force that is concentrated at the connection point with the back of the mother when the mass is impacted from the tip body side. It has a length sufficient to be as small as possible at the tip, and has the appropriate hardness and elasticity in relation to the material.

Therefore, the present invention is filled in the state that the rod body of the reinforcing member is densely filled in the inner space of the U-shaped groove of the mother flesh, united with the mother flesh, and both of them are integrated. Its remarkable superiority and the length of the rod body is longer than that of the prior art, and the magnitude of the impact force applied to the distal end thereof is significantly smaller than that of the prior art. The inconvenience of refracting from the site can be reliably prevented.

At that time, the reinforcing member is provided on the outer surface of the rod-like body in the swelling direction along the longitudinal direction, so that the strength of the reinforcing member is further increased, so that the effect can be more certain.

(2) The reinforcing member is formed integrally with the connecting projection with the supporter, so in connection with the supporter, the reinforcing member is attached only to the mother's arm and attaches a special connection member with the other supporter. There is no need to do this, and it is possible to simplify the connection process between the mother meat and the buttocks as much as possible, which is suitable for mass production.

(3) The reinforcing member is not only extremely strong but also lightweight because its material is made of fibers such as glass fiber, and the reinforcing member not only reinforces the mother's flesh but also serves as a connecting member with the underlay. Even if it is installed, it is suitable for use without increasing the mass of mass production.

(4) The caulking point of the mother flesh and the reinforcing member is sufficient at two places at both ends of the rod body, but in the case of three places as described above, the adhesion between the mother flesh and the reinforcing member can be further strengthened. , Suitable.

Even if a caulking point is provided on the tip body side outer portion of the connecting projection where the impact force is concentrated, the rod-shaped body of the reinforcing member is remarkably superior in absorbency of the impact force as described above. And there is no problem in maintaining the strength of the reinforcing member.
