On both sides of the flange 60, the flange 6o is cut inward. , hook portions 64a and 64b having engaging surfaces 65a and 65b, respectively, are formed. .

The female locking member 70 is designed to fit into a groove formed in the edge 11c of the floor member. Positioned. The female lock member 70 is made of the same material as the male lock member 5o. It can be manufactured by various materials and processes. Further, the member 7o has upper and lower parts joined to each other. It is formed of two half-holes 71 and 72. In order to facilitate manufacturing, both halves 71 and 72 have the same shape, and when one is turned over and assembled to the other, the female lock part It is also possible to form a frame or skeleton of the material 7o.

The female locking member 70 has a large size for receiving the flange 60 of the male locking member 5o. It includes a central concave portion 85 of the kina.

FIG. 15 shows one half of the female locking member 7o. especially , half 71 is shown from the inside, that is, from the inner side facing the recess 85. Female type B The hook member and its two halves have oil portions or extensions 79 at each end. Applicable A through hole 73 is formed in the extending portion, and a threaded insertion hole 40 (see FIG. 2) is formed in the through hole 73. A screw is inserted into the floor panel to fix the lock member to the floor panel.

At one end there is a pin 76 and at the outside a bevel or countersink. A hollow hole 77 is provided. At corresponding locations on the other end, holes 77 and 75 are arranged. The two halves 71, 72 connect the alignment pins 76 of one half to the other. It is assembled by inserting it into the corresponding hole 77 of the half body. The two halves have hole 7 4 and 75 are fixed to each other by screws inserted therethrough.

As seen in FIG. 1, a pair of pins or rollers 80a and 80b When the flange 6o is inserted into the lock position, the flange 60 is in a position where it substantially contacts the flange 60. It is positioned within the recess 85 as shown in FIG. Pins 80a and 8°b are small cylindrical metal pieces, and are installed with their axes perpendicular to the floor plane. Also, long holes 8 formed in the top member 71 and bottom member 72 of the lock member 70, respectively. 1a and 81b.

These long holes extend perpendicularly to the edge direction of the floor member, and The reason will be explained later. Additionally, these long holes form passages for pins 80a and 80b. do.

The female locking member 70 also includes springs 90,9 disposed along the back side of the member 7o. Contains 1. As shown in FIG. 4, one spring 90 is attached to the locking member 7o. The spring includes a back portion 92 extending along the back surface and beyond the through hole 73; , the lock member is secured to the floor member by a screw passing through the through hole 73. is fixed to the hook member 70. The spring 90 is also located at the center of the length of the back surface of the locking member 7o. It includes a tip 94 that extends slightly beyond the point. The spring 90 further includes: a side portion 96a connected to the spring 9o or integrally formed with the spring 90; 96b, and the side portions extend from both sides of the locking member 70 beyond the area including the hole 81a. Extends as a plate-like member along the sides. A locking member 7o is formed on the edge of the floor member. The thickness of the locking member is kept to a minimum so that it can be easily fitted into the groove. Therefore, the side portions of both halves 71 and 72 constituting the locking member 7o are aligned with the above-mentioned side of the spring 9o. It has a thin area that receives the portions 96a, 96b.

The side portions 96a, 96b have portions overlapping with the long hole 81a with a different slope from that of the long hole 81a. It has a long hole 1ooa formed therein. Regarding the importance of the slope of this long hole 100a, This will be further explained later in the operation explanation section. In the preferred embodiment, the elongated hole 81a , 81b (7) is wider than the width of the elongated holes 100a, 100b, and the pins 80a, 80 b has a reduced diameter portion at both ends thereof, the diameter of which matches the width of the elongated holes 100a and 100b. Pi The main body portions of the holes 80a, 80b have diameters that match the long holes 81a, 81b.

It is inserted into the long holes 81a and 81b, and the reduced diameter portions at both ends are accommodated in the long holes 100a and 100b. As a result, the pins 80a and 80b are positioned in the axial direction and aligned with the long holes. Shedding is prevented. The movement of tenobin Boa and 80b in the long holes 81a and 81b is caused by springs. This depends on the deflection of 90°91, and as the pin moves, the elongated hole 100a , 100b move along the long holes 81a, 81b.

At the other end of the female locking member 70, the spring 91 is also inserted through the bolt insertion hole 73. The rear portion 93 is fixed to the locking mechanism, and the tip 95 is located at the center of the locking member 70. It extends beyond and overlaps the tip 94 of the spring 90.

For example, as shown in FIG. Sometimes, a long hole is formed such that the tip 94 passes through the tip 95.

The halves 71, 72 also have in their central part transverse to the direction of extension of the edge of the floor element. It has an elongated hole 110 that extends. This elongated hole has a release cam 1 used to release the engagement. 21 is retained. As shown in FIG. 15, each half 71, 72 has a slot 1 It has a pin 111 on the side of 10.

The release mechanism 120 includes a cam member 121 shown in enlarged detail in FIG. There is. This cam member is made of metal or other durable material and has a is flat and fits snugly into the recess 85 between the halves 71, 72 of the female locking member 70. It is thick enough to fit. However, the collar part 122 is lower than the surface of the cam member 121. It also protrudes upward and fits into the elongated hole 110. Also on the opposite side of the cam member 121 (first There is a similar collar (not shown in Figure 3) on the lower half of the locking member 70. 72, which fit into corresponding slots 110 (not shown in FIG. 1). . The cam member 121 has a somewhat elongated shaped tip 123 with a rounded end. , this tip engages with the spring of the locking mechanism, particularly the tip 94 of the spring 90. cam Member 121 also has a flat surface 124 and three surfaces 125, 126, 127. have The angle between surfaces 125 and 126, and the angle between surfaces 126 and 127 The angle of the flange 60 of the male locking member 50 in contact with these surfaces at various locations is The notch 630 matches the angle formed by the two inner surfaces. The empty part 122 is a long hole 1 Although generally cylindrical in shape with a diameter matching the width of 10, the protrusion 128 is larger than the width of the elongated hole 110, and therefore, as shown in FIGS. 6 to 8, the cam portion It serves to limit the rotation of the material 121 to approximately 90 degrees. Kara part 122 is also hexagonal Equipped with a hexagonal hole for a key type wrench. The cam member 121 further includes a cam surface 131. 3, and on the opposite side to that shown in FIG. It has a thin wall part.

1-11 way Before engaging the locking member, the springs 90,91 are attached to the screws as shown in FIG. 1, in which the pins 80a and 80b are held near their centers. Solution The cam member 121 of the removing mechanism 120 is rotated counterclockwise as shown in FIG. If the cam member is locked on the opposite side or below the locking member, the clock direction) so that the flat surface 124 is parallel to the rear edge of the female locking member 70; It contacts the tip 94 of a spring 90 which holds the cam member in that position.

1 and 5, the locking members 50 and 70 are shown facing toward the other party from the front, that is, from the front. The arrow represents the movement in the direction perpendicular to the direction of extension of the edge 11a, llc of the a member. A mark 150 is shown. The locking member is assembled in this direction as described below. and then multiplied. However, if the locking member is pushed at the angle shown by arrow 155 in FIG. It is a good idea to know that it is okay to do this and then combine them. This already applies to many e.g. of the floor members are combined, and the two floor members that will be adjacent When trying to assemble another floor member into the recess formed in between, therefore, e.g. For example, the side portions 11a and llb and the corresponding male and female lock portions may be engaged at the same time. This is important when it is necessary to match the This other floor member has its edges Slide into the recess approximately parallel to the edge of the already assembled floor component. However, when you slide it in at the end, align the lock part at an angle of about 45 degrees. It will be possible to The locking mechanism of the present invention can be used from the front or from either side. This allows engagement at an angle of 45 degrees.

As male locking member 50 moves toward engagement with female locking member 70, Flange 60 is received within recess 85. Front edge 62a, 6 of flange 60 2b are engaged with pins 80a and sob, respectively, and have front edges 62a, 62b and long holes 81a, Due to the angle and inclination of 81b, the bins 80a and 80b are defined within the long holes 81a and 81b. move outwards and backwards along a path of movement. In order to do this, The holes 100a and 100b formed in the holes 90 and 91 are the long holes 81a, It must be able to bend so that it can follow the movement of bottles 8Oa and 80b in 81b. stomach. This state is shown in FIG. In this figure, the two locking members are in contact. However, the engaged state has not yet been reached, and the bottles 80a and 80b are in front of the flange. It rests on the outside of the edges 62a, 62b, and the springs 90, 91 are deflected. Figure 5 Proceeding further from the state, there is a bottle 80a.

80b goes around the corners of the flange front edges 62a, 62b and hooks 64a, 64. Move to b. This returns the spring to its normal position and the bins 80a, 80b are replaced. to the inner hook recess. This situation is shown in Figure 6, where two floors The parts are engaged with each other. The two opposing locks are combined Depending on the inclination of each lock when It fits perfectly into the hook part of 0, and both bottles are in place at the same time. It's good to know that there are times when you can complete a lock engagement.

In this engaged state, the two locking members 50.70 are then The edges of the parts cannot be separated. This will pull the lock apart The force causes the engaging surfaces 65a, 65b to lock onto the bottles 80a, 80b, and the bottles By pressing against the side walls of the long holes 81a and 81b. In this way, collision occurs and the lock This prevents the lock member 50 from being pulled out. The angle or inclination of the engaging surfaces 65a and 65b is The angle is selected to be extremely small compared to the inclination angle of the elongated holes 81a and 81b. Like In a preferred embodiment, this angle is about 10 degrees. That is, in this preferred embodiment The angle of the surface 65a with respect to the edge of the floor (Fig. 1) is 55 degrees, and the long hole 8 The inclination angle B (FIG. 2) of 1b is about 45 degrees, and the difference between the two is about 10 degrees.

The only way to release the mating members is through the bin 80a.

80b outwardly within its elongated hole, but the bins 80a, 80b The angle of the engaging surfaces 65a, 65b relative to the angle of the elongated holes 81a, 81b that engage and move The degree of force in the direction parallel to the slot is sufficient for the applied force to displace the bottle. It is set to have no minutes. Conversely, most of the force is in the direction perpendicular to the side wall of the long hole. This creates friction and collision, preventing the lock from releasing.

In addition, the strength of the connection between the lock member and the flange 60 is determined by the fact that the lock part on the negative side is adjacent to the When lifting a floor member that is engaged with another floor member from the opposite side, It is strong enough to withstand considerable rough handling.

To release such a lock, it is necessary to move the bins 80a and 80b outward. This is because the bottle retracts outward and comes off the hook parts 64a, 64b, and the lock is removed. By bending the springs 90 and 91 so that the lock member 50 can be pulled out. It will be done. Of course, when a large load is applied to the lock part, this release mechanism You may also not be able to move the bin. However, it is suitable for floor materials. Only a certain load is acting on them, or they are simply connected next to each other with no load. In this case, the release cam 121 enables the above operation.

In order to perform the above operations, an opening is provided on the top surface of the floor along the edge. A hexagonal key type wrench is inserted into the hexagonal hole 129 of the collar portion 122. this wrench (In the state shown in Fig. 6) If you twist the locking mechanism approximately 90 degrees counterclockwise, the locking mechanism will open as shown in Fig. 6. The state changes from the matching state to the state shown in FIG.

In FIG. 6, cam member 121 has its flat surface 124 connected to the locking mechanism and spring. The inner surface of the notch 63 of the flange 60 is parallel to the edge of the flange 60. It was in contact with surfaces 124 and 125 of cam member 121. Tighten the cam member 121 with a wrench. By rotating, the surfaces 125 and 126 are now cut out, as shown in FIG. The tip 123 comes into contact with the inner surface of the spring 63, and the tip 123 removes the tip of the spring 90.91. push it towards you. The cam member rotates through the large diameter section between surfaces 126 and 127. Some movement along the elongated hole 110 may be necessary.

After the release mechanism has been rotated to the position shown in Figure 7, the wrench can be removed. The release mechanism then remains in the position shown. This state is not completely stable. However, if the two floor members remain in the same position, the 6° notch on the flange or the cam part This state is maintained while in contact with surfaces 125 and 126 of material 121. At this time , since the two pins 80a and 80b are in the retracted or released position, the two floor members can be separated. When separated, as shown in Figure 8, The cam member 121 initially moves outward within the slot 110 and is pulled out to release the male rod. flange 60 of the hook member. The pins 80a and 80b in the retracted position are After the locking parts 64a and 64b are removed, the male locking member and the female locking member are further removed. When the cam member 121 separates and begins to move, the cam surface 131 (Fig. 3) engages the female locking member. It locks with the pin 111 (FIG. 15) on the half body 71. As a result, the cam member 1 21 pivots slightly clockwise as shown in FIG. Push out the cam member 121 to the release position shown in FIG. In this position, Place the pin 111 of the female locking mechanism half 72 against the surface 132 of the cam member 121 and lock it. Further rotation of the arm member from the position shown in FIG. 9 may be prevented. If you do this , the tip 123 rotates and enters the recess 85, preventing the flange 60 from entering. You can prevent it from getting in the way. In the state shown in Figure 9, the cam member and spring have returned to their respective initial positions, and the pins 80a, 80b are movable inwardly; The locking member is ready to receive the flange 60 in preparation for the next locking operation.

If desired, a male or female locking member may be attached to the beveled edge member (not shown). It is also possible to provide Therefore, as is commonly known, the underlying floor surface slope to form a gentle transition from the top of the portable floor to the top surface of the portable floor. An edge member with a Ru.

As shown in the above description and the attached drawings, the applicant has found that easy operation and confirmation of adjacent panels are possible. Improved locking means and improved floor elements for a real and solid interconnection structure.
