Description

  The present invention relates to a reinforced frame body that reinforces a tent, a sunshade, and the like, and more particularly to a reinforced frame body that reinforces a tent and the like by connecting support columns of a folding tent.

  A tent used outdoors is usually formed by supporting a roof structure frame with four pillars, expanding the roof structure frame, and covering it with a awning. It is performed exclusively at the upper part of the support (Patent Document 1). Therefore, in a tent having such a structure, when an external force from a lateral direction due to a cross wind or the like is applied, the stress concentrates on the connecting portion between the support column and the structure, and the tent tends to bend easily and break easily.

  In particular, in recent years, in order to make it easy to carry, the various members that make up the columns and the roof structure frame body are often made of plastic or thin metal, so that they have sufficient strength against wind and external stress. Tend to be difficult to maintain.

  On the other hand, in order to reinforce the tent, it is effective to connect the adjacent struts. However, if the tent is to be reinforced, the weight of the tent increases and the transportation is hindered. In addition, depending on the location to be reinforced, it may be difficult to use the tent because it is difficult for people to go in and out.

  Therefore, in order to reinforce the tent, it can be attached to and removed from the tent so that it can be used according to the usage conditions such as weather conditions, and it also interferes with the roof structure frame body so that it does not get in the way when people enter and exit the tent. Therefore, it is desired to develop a reinforcing frame body having a structure that can be attached to the upper portion of the column without doing so.

JP 2005-2699 A

  The present invention can reinforce the tent by connecting adjacent struts as needed, and the upper part of the struts without interfering with the roof structure frame so that people do not get in the way when entering or leaving the tent. It is intended to provide a reinforcing frame body for a tent that can be attached to a tent.

  In order to solve the above-mentioned problems, the present invention adopts a reinforcing frame body provided with joint portions at both ends of a pipe for connecting the struts of adjacent tents to reinforce the tent, wherein the joint portion is at least a base. It consists of a clamp member and a lock clamp member, and the base clamp member has a groove-like recess for holding the support on the bottom surface of the base and an insertion hole for inserting and fixing the end of the pipe on the top surface of the base. A cylindrical portion, and an extension line of the insertion hole so that it intersects the groove of the groove-shaped recess in a three-dimensional manner and at a right angle, and the lock clamp member is a groove shape for holding the support post together with the base clamp member on the bottom surface of the base A concave portion is provided, and the joint portion at both ends is joined to two adjacent struts to fix the pipe at a right angle to the strut while being positioned on a plane parallel to the plane including the two struts. Characterized in that made it possible to reinforce the tent without interfering with structure constituting the roots.

  Furthermore, either one of the base clamp member or the lock clamp member is provided with a through-hole for passing the screw shaft, and the other base is provided with a screw hole that is screwed with the screw shaft. The base clamp member and the lock clamp member are joined by screwing into the screw hole of the other base while passing through the through hole of one base.

  Furthermore, the cylindrical portion of the base clamp member should be installed on the opposite side of the top surface of the base from the groove-shaped recess so that the insertion hole is at an angle of 45 degrees with respect to the bottom surface of the base. Features.

  Furthermore, the groove-shaped recess of the base clamp member is characterized in that the vertical cross section with respect to the longitudinal direction of the groove is V-shaped.

  Further, the groove-shaped recess of the lock clamp member is characterized in that the vertical cross section with respect to the longitudinal direction of the groove is V-shaped.

  Furthermore, the groove-shaped recess has a V-shaped cross section perpendicular to the longitudinal direction of the groove, and the two planes forming the groove form an angle of 45 degrees with the bottom surface of the base. Characterized by

  Furthermore, a non-slip member is disposed in the groove recess.

  Furthermore, a guide pin is provided upright on the bottom surface of one of the base clamp member and the lock clamp member, and a guide pin receiving hole for inserting the guide pin is provided on the bottom surface of the other base. Thus, the base clamp member and the lock clamp member can be joined while being aligned.

  Furthermore, the pipe length can be adjusted by inserting an adjustment pipe for adjusting the length of the pipe into the central portion of the pipe by being inserted into or inserted into the pipe.

  The tent reinforcing method using the tent reinforcing frame body is also characterized.

  Also, in a tent reinforcing method in which two tent reinforcing frame bodies are joined to a supporting pole with one supporting pole interposed therebetween, the two joint portions of adjacent tent reinforcing frame bodies sandwich the supporting post between base clamp members. And a tent reinforcing method for reinforcing the tent.

  By using the reinforcing frame body of the present invention in a conventionally known folding tent and connecting two adjacent struts, when receiving external force such as wind power, the roof structure frame body can be deformed or damaged. It is possible to prevent the deformation and damage of the columns connected by the roof structure frame.

  The reinforcing frame body of the present invention can be fixed to the support column at any desired height. For this reason, it is possible not only to use the reinforcing frame body for the purpose of reinforcing between the struts but also to suspend a lightweight article such as a sunshade sheet or a bulletin board on the reinforcing frame body. It can also be used.

  When the reinforcement frame body is joined to the column, the pipe of the reinforcement frame body is located on a plane parallel to the plane including the two columns, so that the roof structure frame body is also provided on the upper portion of the column that is connected to the roof structure frame body. It can be installed without interfering with. Therefore, in a folding frame type tent that has become the mainstream in recent years, even if the roof structure frame body is made of a scissor assembly using the X frame, the struts between the two locations where the X frame joins are exposed. The reinforcing frame body of the present invention can be joined using the portion.

  Furthermore, when two tent reinforcing frame bodies are joined to the struts with one strut sandwiched to reinforce the tent, the two joint portions of the adjacent tent reinforcing frame bodies are connected to each other by the base clamp members. Because it can be clamped, the space required to join two joints can be reduced to one joint, and even if the part where the column is exposed is a small narrow part, use that part Thus, two tent reinforcing frame bodies can be attached.

The male base clamp member (3) is provided with a groove-shaped recess (32) so that the groove opens to the bottom surface (31b) of the base (31), and is inserted and fixed to the end of the main pipe (2). The cylindrical portion (34) having the insertion hole (38) is provided on the top surface (31a) of the base (31), and the extension line of the insertion hole (38) and the groove of the groove-shaped recess (32) , Arranged so as to cross three-dimensionally and at a right angle. It is desirable to attach a non-slip (33) to the contact surface (32a). A guide pin (35) is formed near the center of the base (31), and a spacer (36) is formed to protrude from the surface of the base (31) at the upper right part of the guide pin (35). A through hole (37) is formed below the guide pin (35).

  The cross section of the groove-shaped recess (32) is substantially V-shaped, and the angle formed by the contact surfaces (32a) (32a) is preferably 90 degrees. The contact surface (32a) of the groove-shaped recess (32) is The inclination angle θ1 with respect to the bottom surface (31b) of the table (31) is preferably 45 degrees. The cross-section of the groove-shaped recess (32) is substantially V-shaped, which corresponds to the fact that the shape of the support column of a commercially available folding tent is usually a prismatic column. This is because the support can be held without any problem. In addition, the angle formed by the contact surfaces (32a) and (32a) is 90 degrees and the inclination angle θ1 is 45 degrees when the reinforcing frame body is joined by sandwiching the pillars of the square pillar (2 ) Is easily arranged along the side of the tent. However, since these shapes should be set according to the shape of the column or the shape of the tent, they are not limited to this.

  The cylindrical portion (34) is inclined (inclination angle θ2) to the opposite side of the groove-shaped concave portion, and the insertion hole (38) is installed at an angle of 45 degrees with the bottom surface (31b) of the base (31). It is preferable to do. As will be described later, when two tent reinforcement frame bodies are joined to the support poles to reinforce the tent with one support pole interposed therebetween, the two joint portions of the adjacent tent reinforcement frame bodies are base clamps. This is because the tent can be reinforced by sandwiching the column between the members (FIG. 10) (FIG. 11), but the two pipes extending from the joint portion are at right angles.

  FIG. 3 shows the female base clamp member (4) fitted to the end of the opposite main pipe (2). 3A shows the front of the female base clamp member 4, FIG. 3B shows the same side, FIG. 3C shows the back, and FIG. 3D shows the central longitudinal section. The female base clamp member (4) has a groove-shaped recess (42) having a substantially V-shaped cross section with an anti-slip (43) attached to the inner surface, and a groove opening in the bottom surface (41b) of the base (411). Provided with a cylindrical portion (44) having an insertion hole (48) for inserting and fixing the end of the main pipe (2) on the top surface (41a) of the base (41). The extension line of the hole (38) and the groove of the groove-like recess (32) are arranged so as to intersect three-dimensionally and at a right angle. A guide pin receiving hole (45) is formed near the center of the base (41), and a spacer (46) projects from the surface of the base (41) at the upper right portion of the guide pin receiving hole (45). Further, a screw hole (47) is formed below the guide pin (45). The angle of the contact surface forming the groove-shaped recess and the angle of the cylindrical portion (44) with respect to the base (41) are set to be the same as those of the male base clamp member (3), and the description is omitted. To do.

  FIG. 4 shows a female lock clamp member (5) used as a pair with the male base clamp member (3) shown in FIG. 2, and has a substantially V-shaped cross section to prevent slippage on the inner surface (53). A groove-like recess (52) to which is attached is provided in a shape that opens to the bottom surface (51b) of the base (51). A guide pin receiving hole (54) is formed near the upper end of the base (51), and a spacer (55) is formed on the upper right portion of the guide pin receiving hole (54) so as to protrude from the surface of the base. A screw hole (56) is formed below the receiving hole (54).

  FIG. 5 shows a male lock clamp member (6) used in a pair with the female base clamp member (4) shown in FIG. ) Is provided in such a shape as to open to the bottom surface (61b) of the base (61). A guide pin (64) is formed near the upper end of the base (61), and a spacer (65) is formed on the upper right portion of the guide pin (64) so as to protrude from the surface of the base, and below the guide pin (64). A through-hole (66) is formed in. The angles of the contact surfaces of the groove-shaped recesses (52) and (62) of the female lock clamp member (5) and the male lock clamp member (6) are also set to be the same as those of the male base clamp member (3). Therefore, explanation is omitted.

  The male base clamp member (3), female base clamp member (4), female lock clamp member (5), male lock clamp member (6), main pipe (2) and adjustment pipe (8) The locking mechanism (9) for connecting the two is preferably made of a material that is not easily deformed or damaged, and the material is preferably high-density polypropylene. Further, the main pipe (2) and the adjusting pipe (8) need to be rigid enough to reinforce between the columns and receive external force, and are preferably made of aluminum in consideration of portability.

  FIG. 6 is a view showing a combination of the male base clamp member (3) and the female lock clamp member (5), and FIG. 7 shows a female base clamp member (4) and a male lock clamp member ( It is a figure which shows how to combine 6). Referring to FIG. 6, a male base clamp member (3) and a female lock clamp member (5) are used with their bases (31b) (51b) facing each other. The male base clamp member (3) and the female lock clamp member (5) can be easily guided to an appropriate position by inserting the guide pin (35) into the guide pin receiving hole (54). Yes. At this time, since the spacers (36) and (55) projectingly formed on the bases (31) and (51) abut against the opposing bases, the male base clamp member (3) and the female lock clamp member (5) The distance between the bases is the same as the protruding height of the spacers (36) and (55), and a space for sandwiching a substantially rectangular column is formed by the groove-shaped recesses (32) and (52) facing each other. The The male base clamp member (3) and the female lock clamp member (5) are provided with a female lock clamp member through the shaft (7b) of the fastening screw (7) through the through hole (37) of the male base clamp member (3). By being screwed into the screw hole (56) of (5), they are connected together and function as a joint part (A) joined to the support column.

  Referring to FIG. 7, the female base clamp member (4) and the male lock clamp member (6) are used with their bases (41b) (61b) facing each other. The female base clamp member (4) and the female lock clamp member (6) can be easily guided to an appropriate position by inserting the guide pin (65) into the guide pin receiving hole (44). Yes. At this time, since the spacers 46 and 65 projectingly formed on the bases 41 and 61 abut against the opposing bases, the female base clamp member 4 and the male lock clamp member 6 The distance between the bases is kept by the protruding height of the spacers (46) and (65), and a space for sandwiching the substantially square support is formed by the facing groove-shaped recesses (42) and (62). Is done. The female base clamp member (4) and the male lock clamp member (6) are connected to the shaft (7b) of the fastening screw (7) through the through hole (66) of the male lock clamp member (6). By screwing it into the screw hole (47) of (5), it is fastened together and functions as a joint part (A) joined to the support column. That is, the direction of the guide pin and the direction of the tightening screw are reversed compared to the combination of the male base clamp member (3) and the female lock clamp member (5). It should be noted that the screwing direction of the fastening screw (7) is not limited to the above example, and may be screwed in the opposite direction.

  When the fastening screw (7) is tightened, the gap between the male base clamp member (3) and the female lock clamp member (5) or the female base clamp member (4) and the male lock clamp member (6) is gradually increased. And the space for clamping with the column formed by the two groove-like recesses ((32) and (52) or (42) and (62)) is narrowed, and the column can be clamped.

  The base clamp members (3) and (4) and the lock clamp members (5) and (6) are inserted into the guide pin receiving holes (44) and (64) with the guide pins (35) and (55) facing each other as described above. Therefore, even if it receives rotation of a fastening screw (7), it has the effect | action which suppresses that the relative angle of a base clamp member (3) (4) and a lock clamp member (5) (6) changes. In addition, when clamping a column that is thicker than the column clamp space, the base clamp members (3), (4) and the lock clamp members (5), (6) use the spacers (36) (36) (55) (65) as fulcrums. Since the column is clamped in a slightly expanded state like a hinge, the lever principle works by the fastening screw (7), and the fastening force of the screw is the groove-shaped recess (32) (42) (52) (62) Can be firmly fixed to the support.

  How to attach to the support will be explained. FIG. 8 shows a state in which the reinforcing frame body (1) is attached to the position of the roof structure frame body (11) in a state where the roof structure frame body (11) provided on the support column (10) is extended. . The roof structure frame body (11) has a structure in which two X-shaped frames are connected, one end of which is connected to the apex of the column (10) via a bracket, and the other end is connected via a slide bracket. It is a conventionally known one.

  First, from the male base clamp member (3) and the female base clamp member (4) of the reinforcing frame body (1), the fastening screw (7), the female lock clamp member (4) and the male lock clamp member (6 ) And then the base clamp members (3) and (4) are brought into contact with the position to be reinforced (not shown). As described above, the contact surfaces (32a) (42a) of the groove-shaped recesses formed in the male base clamp member (3) and the female base clamp member (4) are 45 to 45 from the bottom surfaces (31b) (41b) of the base. The base (31) (41) is at an angle of 45 degrees with respect to the side of the tent when viewed from the longitudinal direction side of the support column, and toward the center of the tent (31) ( It will be in the protruding state by the length of 41). Furthermore, since the cylindrical portions (34) and (44) are formed at an angle of 45 degrees from the bases (31) and (41), the main pipe (2) fitted to the cylindrical portions (34) and (44) (2) is located at a position farther from the roof structure frame (11) toward the center of the tent. That is, the reinforcement frame body (1) can be positioned by avoiding the roof structure frame body (11) even in a place where the columns cannot be linearly connected due to the presence of the roof structure frame body (11). it can.

  Next, the female lock clamp member (4) and the male lock clamp member (6) are arranged at the corresponding positions of the male base clamp member (3) and the female base clamp member (4), respectively, and tightening screws (7 ) Can be used to fasten both the members to clamp the support and fix the reinforcing frame body (1) to the supports (10) and (10). Finally, by using the adjustment pipe (8) and the lock mechanism (9) so that the distance between the main frames (2) and (2) is appropriate, each column is firmly fixed and the wind force is applied from the outside. It is possible to prevent the roof structure frame body, the bracket portion and the support column from being damaged when applied.

  Now, as shown in FIG. 8, the X-shaped frame (11a) constituting the roof structure frame (11) has one end connected to the apex of the column via a bracket and the other end connected via a slide bracket. Therefore, when the roof structure frame body is extended, the gap between the brackets becomes very narrow, and there may be no gap between the brackets to attach a plurality of base clamp members. In this case, two base clamp members cannot be placed side by side on the support between the brackets, and the tent can be reinforced by attaching two reinforcing frame bodies for the tent across one support. I can't.

  However, as shown in FIG. 10, the reinforcing frame body (1) includes two reinforcing frame bodies (1) from which the female lock clamp member (4) and the male lock clamp member (6) are removed. The base clamp member (3) and the female base clamp member (4) can be connected with the bottom surfaces (31b) and (41b) of the base facing each other. That is, the female base clamp (4) can be connected to the male base clamp member (4) as if it were a female lock clamp member (6). In the same way, the female base clamp member (4) sandwiches the column instead of the female lock clamp member, and the fastening screw (7) is inserted into the through hole of the male base clamp member (4). The support column can be clamped by inserting and screwing into the screw hole (47) of the female base clamp member (4) from 37). When the male base clamp member (3) and the female base clamp member (4) are connected in this way, the main pipes (2) and (2) are arranged at positions orthogonal to each other. It becomes possible to fix the column in the L shape at the same height. Further, as shown in FIG. 11, by connecting all four reinforcing frame bodies (1), it becomes possible to fix the reinforcing frame bodies (1) having the same height between the four columns.

  FIG. 12 shows an example in which the reinforcing frame body (1) is fixed to another place where the roof structure frame body (11) does not exist. Since the reinforcing frame body (1) is strong enough to stretch between the columns, it can be directly attached to the main frame (2) or extension frame (8) if it is a lightweight article (15), such as a sunscreen or bulletin board. It can also be used suspended. If the awning is not present, the reinforcing frame body (1) can be fixed so as to protrude not to the inner surface of the tent but to the outer surface of the tent as described above.
