Description

  The present invention connects the vertical frame member and the horizontal frame member in a state in which the surrounding frame body abuts the longitudinal end surfaces of the upper and lower horizontal frame members on the opposing surfaces of the upper and lower ends of the left and right vertical frame members. Concerning the configured gate.

A gate constructed by connecting a vertical frame member and a horizontal frame member in a state where the surrounding frame is in contact with the upper and lower ends of the left and right vertical frame members against the longitudinal end surfaces of the upper and lower horizontal frame members. In the case where the vertical frame member is hollow, the hollow part of each vertical frame member opens in the vertical direction at the upper and lower ends, respectively, so conventionally, in order to improve the appearance of the gate and prevent injury, Corner caps that close the openings of the hollow portions are attached to the upper and lower ends.
nothing special

  However, the vertical frame member and the horizontal frame member constituting the frame body are generally made of an aluminum alloy, whereas the corner cap is made of a synthetic resin. In addition, since the cross-sectional dimension of the vertical frame material is relatively large, for example, about 3 × 8 cm to 5 × 13 cm, the corner cap covering this has the same size, and the corner cap has a secular discoloration, Since the color difference from the frame is conspicuous, it causes the appearance of the gate to deteriorate.

  Recently, in order to enhance the appearance decoration of the gate, a vertical frame member having a double width formed by connecting two conventional vertical frame members horizontally has been used. When a large-sized corner cap that covers the entire upper and lower ends of such a wide vertical frame member is attached, the appearance of the gate is increasingly impaired.

  The present invention has been made in view of the above points, and it is an object of the present invention to provide a gate that eliminates the need for a corner cap and improves the aesthetics of the upper and lower ends of the gate.

  In order to achieve the above object, the present invention covers the entire length of the upper end surface and the lower end surface on the upper end surface of the upper horizontal frame member and the lower end surface of the lower horizontal frame member. It is proposed to install a cover material having a length that can also cover the hollow part.

However, the long cover material can be fixed relatively easily by devising the extrusion shape of the horizontal frame material to the upper end surface of the upper horizontal frame material and the lower end surface of the lower horizontal frame material. However, it is difficult to fix the vertical frame material because it covers the longitudinal end face. The present invention has solved this difficulty as follows.
That is, the present invention connects the left and right vertical frame members and the upper and lower horizontal frame members in a state where the longitudinal end surfaces of the upper and lower horizontal frame members abut against the opposing surfaces in the upper and lower portions of the left and right vertical frame members, In a gate door in which a cover material covering the upper end surface and the lower end surface of each of the horizontal frame members is fitted to the upper end portion of the upper horizontal frame member and the lower end portion of the lower horizontal frame member, the cover member is Extend to the vicinity of the gate width direction end of the vertical frame member on the upper and lower vertical surfaces of the left and right vertical frame members, and vibrate the extended portion of the cover material on the gate width direction end of the left and right vertical frame members. The corner member to be regulated is fixed (Claim 1).

  In a preferred example of the present invention, the upper horizontal frame member has locking edges at both ends in the thickness direction of the upper end portion, and the lower horizontal frame material has locking edges at both ends in the thickness direction of the lower end portion, The cover material is fitted on the upper edge surface of the upper horizontal frame material or the end surface of the lower horizontal frame material, and the engagement edge of the horizontal frame material at both ends in the width direction of the coating portion. The corner member has a front L-shape, and has a fitting groove that is open downward or upward and in the longitudinal direction by the covering portion and the locked edge. A first connection portion that is inserted into the end of the fitting groove of the cover material and coupled to the side, a second connection portion that is inserted into the hollow portion of the vertical frame member and is secured to the vertical side, and a first connection Provided in a bent portion between the first connecting portion and the second connecting portion, and having a block portion that fills a recess formed between the upper and lower end portions of the vertical frame member and a longitudinal end portion of the cover member. It is characterized in that (claim 2).

  The corner member pushes the first connection portion into the fitting groove of the cover material to couple to the cover material, and inserts the second connection portion into the vertical frame material at the gate width direction end of the vertical frame material. It is desirable to fix and attach to the narrow wall of a material with a screw (Claim 3).

  According to the first aspect of the present invention, the cover material extends to the vicinity of the gate width direction end portions of the vertical frame members on the upper and lower end surfaces of the left and right vertical frame members, and is substantially at the upper and lower end portions of the gate door. Since the cover material extending over is visible, the appearance of the gate is improved. In addition, the cover material extends from the upper and lower horizontal frame materials to the gate width direction end portions of the left and right vertical frame materials, but the extended end portions restrict vibrations by the corner members, so the cover material vibrates. Generation of sound is prevented.

  According to the invention of claim 2, the first connecting portion of the corner member is inserted and coupled to the upper and lower cover members, and the locked edge of the cover member is fitted to the locking edge of the upper and lower horizontal frame members. By inserting and fixing the second connection portion of the corner member into the hollow portion of the vertical frame member, the cover member and the corner member can be easily and reliably attached to the gate.

  According to the invention of claim 3, since the cover member and the corner member are not connected with the screw, the screw is not exposed especially on the upper surface of the upper cover member, and the aesthetic appearance is improved.

Next, embodiments of the present invention will be described with reference to the drawings.

  The corner members 7b shown in FIG. 11 are attached to the corner members attached to the lower ends of the door-end side vertical frame member 4a and the suspension base side vertical frame member 4b of the gate 2b. As shown in FIG. 1, a dropping bar R for a lock is attached to the lower end portion of the door frame side vertical frame member 4a of the gate door 2b in the vicinity of the front end of the vertical frame member 4a. Therefore, as shown in FIG. 11, the corner member 7 b has a notch 71 d or a hole that allows the drop bar R to move up and down in the first connection portion 71. In FIG. 11, components corresponding to the components of the corner members 7a and 7d described above are denoted by the same reference numerals.

[Assembling the gate]
The gate according to the present invention is assembled as follows using each component having the above structure. That is, first, as shown in FIG. 2, a panel body 3 is prepared in which horizontal bars 3a and 3b are coupled at least above and below the panel 3c. Next, one end of the upper horizontal frame member 5a in the longitudinal direction is connected to one vertical frame member, for example, the upper end of the narrow wall 41c on the center side in the gate width direction from the upper end surface of the first hollow member 41 of the hanging side vertical frame member 4b. The hole 41g (see FIG. 6) formed in the portion is fitted into the hollow portion of the first hollow member 41 (see FIG. 6). In this case, the hole 41g is formed in the same shape as the contour shape of the remaining portion excluding the bent wall at the upper end of the horizontal frame member 5a, and the horizontal frame member 5a is fitted to the first hollow member 41 with high stability. Is done. The longitudinal end surface of the fitted horizontal frame member 5 a is in contact with the narrow wall 41 d of the first hollow member 41 on the end side in the gate width direction. Then, the projecting edge 42e of the second hollow member 42 is fitted to the projecting edge 41f of the outer narrow wall 41d of the first hollow member 41, and the screw B1 is inserted from the outer narrow wall 42d of the second hollow member 42, The screw passes through the reinforcing plate 8 fixed to the narrow wall 42c on the inner side of the second hollow member 42, passes through the narrow walls 42c and 41d, and is screwed into the screw holes 53a and 53b of the horizontal frame member 5a. The double-width vertical frame member 4b and the upper horizontal frame member 5a, which are the two hanging door side vertical frame members, are connected in an L shape. Both the door end side vertical frame member 4a and the upper horizontal frame member 5a are connected in an L shape in substantially the same manner as described above. As a result, one upper horizontal frame member 5a and left and right vertical frame members 4a and 4b are connected in a gate shape, and the panel body 3 is fitted into the gate-shaped frame, As shown in FIG. 6, the horizontal rail 3a is fitted into the lower fitting groove 56 of the upper horizontal frame member 5a. That is, the pair of protruding edges 32 of the horizontal rail 3a are fitted between the pair of locking edges 56 of the upper horizontal frame member 5a to be temporarily fixed.

  Subsequently, the lower horizontal frame member 5b is connected to the open side of the frame assembled in a gate shape in the same manner as in the case of connecting the upper horizontal frame member 5a to the vertical frame members 4a and 4b. That is, the lower horizontal frame member 5b is fitted to the lower end portion of the first hollow member 41 of the door-end side vertical frame member 4a, and the longitudinal end face of the lower horizontal frame member 5b is connected to the outer narrow wall 41d of the first hollow member 41. , The screw B1 is inserted from the outside of the second hollow member 42, penetrates the reinforcing plate (not shown) and the narrow wall 42c inside the second hollow member 42, and the outer narrow wall of the first hollow member 41 By screwing into 41d and the screw holes 53a and 53b of the lower horizontal frame material 5b, it is connected also to the suspension side vertical frame material 4b in the same manner as described above. As described above, the upper and lower horizontal frame members 5a and 5b and the left and right vertical frame members 4a and 4b are arranged on the outer periphery of the panel body 3, and the longitudinal end surfaces of the upper and lower horizontal frame members 5a and 5b are arranged on the left and right vertical frame members 4a and 4b. A gate connected in a state of abutting on the opposite surface is configured.

  Next, the corner member 7a is joined to the longitudinal direction end of the upper cover member 6a. That is, as shown in FIGS. 13 and 14, the first connection portion 71 of the corner member 7a is fitted between the cover portion 61 of the cover material 6a and the side walls 62 on both sides, as shown in FIGS. At the same time, the projection 71a of the first connecting portion 71 is fitted into the notch 65 of the cover member 6a. Further, as shown in FIG. 14, the locked edges 63 on both sides in the width direction of the cover member 6a are connected to the first end of the corner member 7a. The cover material 6a and the corner member 7a are joined by engaging with the engaging edges 71b on both sides of the one connecting portion 71. At this time, the end surface in the longitudinal direction of the cover member 6a is in close contact with the end surface on the first connection portion 71 side of the block portion 73 of the corner member 7a.

  In the case of the corner member 7 a ′ shown in FIG. 9, the first connecting portion 71 is formed at the fitting groove 64 at both ends of the upper cover member 6 a and the one end portion of the lower cover member 6 b by the action of the protrusion 71. By being press-fitted into the fitting groove 64, it is firmly connected. In the case of the corner member 7b shown in FIG. 11, the first connecting portion 71 is firmly coupled by press-fitting into the fitting groove 64 in the other end portion of the lower cover member 6b by the action of the protrusion 71. .

  As described above, the upper cover member 6a having the corner members 7a (or 7a ') attached to both ends thereof is brought close to the upper surface of the upper horizontal frame member 5a, and the cover member 6a is moved to the end from the center in the longitudinal direction. In order, as shown in FIG. 6, a pair of locked edges 63 on both sides of the cover material 6a are connected to a pair of engagement on both sides of the upper end surface of the horizontal frame material 5a. Using elastic deformation and restoration to the stop edge 54, male and female are fitted and fixed, and the second connecting portion 72 of the corner member 7a (or 7a ') is connected to the trapezoidal portion 42g of the left and right vertical frame members 4a and 4b. Inserted, abutted against the narrow wall 42h, screw B2 from the outside of the narrow wall through the narrow wall 42d, screwed into the hole 72a and the boss 72b of the second connecting portion 72, the corner member 7a (or 7a ′) is fixed to the vertical frame member 4b.

At this time, the block part 73 of the corner member 7a covers the upper surfaces of the trapezoidal part 42g and the dovetail groove 42h of the vertical frame member 4b (see FIG. 13). Further, the block portion 73 of the corner member 7a fills a recess between the longitudinal end surface of the cover member 6a and the upper end surface of the trapezoidal portion of the vertical frame member 4a and the upper end surface of the dovetail groove 42h. Therefore, the appearance of the corner of the gate is improved.
A vertically symmetrical cover material 6b is attached in the same manner between the lower side frame material 5b and the corner members 7b attached to both corners of the lower end of the gate, and is attached to the door-end vertical frame material 4a. Allow the rod R to move up and down.

  As described above, since the cover members 6a and 6b are extended from the end portions of the upper and lower horizontal frame members to the end portions of the vertical frame members, the conventional corner cap having a large area becomes unnecessary, and therefore Cover material that is continuous over the entire length of the end is installed, and a corner member is installed between the end of the cover material and the end of the vertical frame material, so that no depression is produced in the corner of the gate, so the appearance of the gate is It becomes very simple and provides a novel aesthetic. And although the cover material is extended to the edge part of a vertical frame material, since the edge part is being fixed to the vertical frame material by the corner member, the vibration of the edge part of a cover material is prevented and a noise is generated. There is no fear.

  The reason why the cross-sectional shape of the vertical frame members 4a and 4b on the side in the gate width direction is trapezoidal as shown in FIG. 4 is that the hinge for supporting the gate 2a on the gate pillar 1 as shown in FIG. As shown in FIG. 16, the width of the 1 'site in and out of the site is made as small as possible. Further, as shown in FIG. This is because it can be mounted without protruding from the surface of the gate. In FIG. 15, reference numeral 10 denotes a member that closes the gap between the gate pillar 1 and the suspension side vertical frame member 4 b.
