Description

[Detailed Description of the Invention] (1) Industrial Application Field This invention relates to a connecting top for a vehicle, and the top sheet itself, which is the main component of the top, is provided with an engaging body so that it can be easily and securely attached to the hollow top frame. It also relates to a labor-saving connecting hood that can be easily repaired and repaired. (2) Conventional technology Conventionally, wide waterproof fabric made of synthetic fiber cloth treated with synthetic resin has been mainly used for the hood sheet of a rectangular tube-shaped connecting hood for a vehicle. In cases where the bones are made of elastic steel wire, it is well known that wrapping a canopy sheet around the canopy bone and suturing it is extremely inefficient, and it is difficult to repair damage. This brings about Regarding the technical solution of this, the applicant
(a) JP-A-57-60176, (Fig. 13-1, (b) Utility patent application No. 122662-1982, (Fig. 13-2, (c) JP-A-1982-
2862, (proposed as shown in Fig. 13, etc.).In other words, in (a) above, the same type of hood sheet material is attached to the hood rib by a small width in the hood sheet attachment groove 2 constituting the hollow hood rib 1 of the hood frame. Flexible engagement core materials 13 such as solid round rods formed on both sides of the hood sheets S ₁ and S ₁ are fused and fixed and stretched across each hood frame, and the above-mentioned
In (b), flexible engaging core members 14 in the shape of an arrow bar are integrally fused and fixed in the longitudinal direction at predetermined intervals in the width direction of one side surface of the hood sheets S ₂ and S ₂ . This core material is inserted into the hollow hood rib 1 in a folded and rolled state so as to be enclosed by the hood sheet, and is engaged with the hood rib attachment groove to connect and attach the hood sheet to the entire hood frame.
However, in these proposed examples (a) and (b), although the installation of the top sheet is simple, both the flexible engagement core materials 13 and 14 are capable of engaging the top sheet with the top rib attachment groove.
Since the molded synthetic resin must be fused and fixed to the hood sheet, which increases the cost, it is desired to reduce the cost. Further, in the proposed example (c), wide single-piece canopy sheets S ₃ , S ₃ are placed inside the hollow canopy rib 1.
After the hood sheet is bent and inserted, a separate flexible engagement core material 15 molded into a specific shape is inserted into the hollow part of the hood sheet and inserted into the hood rib attachment groove. Although it has the great effect of directly covering the wide hood sheet with the edge of the hood, it is necessary to manufacture the engaging core material 15 as an extrusion molding, and when installing the hood sheet. However, since there are some complicated operations such as inserting the engaging core material into the hood sheet, and two-step work is required in order to attach the engaging core material to the top sheet, similar to the above examples (a) and (b), it is easier to It is desired to reduce costs through installation and labor savings. (3) Problems to be Solved by the Invention In view of the above, the present invention provides a method for fixing a flexible engagement core material on the top sheet by fusion or separately molding it when attaching the top sheet to the top rib attachment groove. A rivet is driven into the wide hood sheet itself without using an engagement means such as using a hood, and the rivet is used as an engagement body part for attaching the hood sheet to the hood frame, and this engagement body part is adapted to the assembly configuration of the hood frame. The above-mentioned rivet-equipped hood sheet is folded and removably inserted along the attachment groove of the hood rib, and an engaging body part cast near the folded top is engaged with the attachment groove to lock the hood sheet at once. and can be held within the hollow tube of the canopy. The purpose of the present invention is to propose the improvement and development of a canopy sheet with an engaging body, which is the main component of the canopy, with the aim of saving labor so that it can be partially replaced even if the canopy is damaged while the vehicle is running. (4) Means for Solving the Problems In order to achieve the above-mentioned object, the present invention covers the continuous mounting grooves of each of the mutually adjacent hollow hood ribs with a wide hood sheet and directly covers the inner peripheral surface of each hollow hood rib. When installing,
After spreading the hood sheet horizontally and placing an appropriate number of rivets on the hood sheet at intervals in the vertical and horizontal directions, exposing the rivet heads on the front and back surfaces of the hood sheet and clamping and fixing them,
The hood sheet is bent in the longitudinal direction along the base of the rivet head in each column, and the bent portion of the hood sheet head is pushed into the hood bone, and the bent hood sheet extends outward from the mounting groove. The bent portion is pushed into the adjacent canopy bone in the same manner as described above, and the rivet head near the top of the bent portion serves as an engaging body portion that locks the canopy sheet to the edge of the mounting groove and is inserted into the canopy bone. configured to engage.
However, when arranging a required number of rivets at intervals in the longitudinal direction of the engaging body of the hood sheet itself or the rivet sheet, the hood sheet is folded along the arranging positions and the vicinity of the top of the fold is bent. At the lower part of the folded top of the folded top sheet, a rivet is inserted perpendicularly to the folded top of the folded top sheet. The rivet head is exposed and the engaging body part is formed, and the overlapping part is removably inserted into the hollow tube along the canopy mounting groove, and the engaging body part formed at the bent overlapping part is engaged with the edge of the mounting groove. It is also possible to adopt a structure in which the folding hood sheet can be applied in a locked manner, so that the folded portion or overlapping portion of the hood sheet of the engaging body portion can be separated and continuously extended on both sides of the mounting groove. The hood sheet is then connected to each adjacent hood bone and installed into the hood bone by repeated operations similar to those described above, thereby stretching the hood sheet over the entire hood frame. (5) Function This invention corresponds to the vertical interval (width direction) of the canopy ribs constituting the canopy frame, and the inner peripheral direction of the canopy ribs (the longitudinal direction in which the canopy is attached along the longitudinally continuous mounting groove). A rivet head is driven onto the top sheet of the hood, and this rivet head constitutes an engaging body portion that engages with the edge of the mounting groove, so the wide hood sheet can be directly installed on each hood frame of the hood frame. When installing the hood sheet, place the hood sheet on adjacent hood ribs, bend the hood sheet in a direction that connects the engaging body parts arranged in the longitudinal direction, and move the hood sheet while pushing it into the hollow pipe along the installation groove in the folded state. The folding hood sheets are installed in a temporarily inserted state due to their own elasticity, and the folding hood sheets are installed separately extending outward on both sides of the mounting groove, and connected hood sheets are installed inside the adjacent hollow tubes, respectively, on the outside of the mounting groove. When pulled, the bent top of the folded hood sheet moves in the direction of the mounting groove, and the rivet heads of the engaging body parts configured on the inside and outside of the bent top close the mounting groove and engage at the edge of the mounting groove. Since the hood sheet is clamped and fixed, there is no risk of the hood sheet coming off outward.Alternatively, the above-mentioned engagement body portions arranged in rows in the length direction of the hood sheet can be formed in advance by adjusting the length of the hood sheet. In an application example in which the engaging body portion is formed by folding the hood sheet along the alignment position and driving a rivet on the folded overlapping surface below the folded top surface, the operation is almost the same as described above. By inserting the bent and overlapping portion of the hood sheet into the hollow tube from the end surface in a removable manner, the engaging body portion is fixed to the bent and overlapping portion of the hood sheet with the rivet head. Therefore, at the same time as the bent portion is inserted, the head rivets on both sides that form the engaging body portion engage with the mounting grooves, and the top sheet can be installed even more quickly. By changing the arrangement of the rivets set in the length direction of the wide hood sheet depending on the form of the assembly frame, it is possible to bend the rivets in the length direction and place the corresponding part of the bent top into the mounting groove. While applying the hood sheet, the hood sheet can be placed between the hood ribs, and the hood sheet can be immediately stretched in one operation.In addition, when applying the hood sheet of this invention to each hood rib, the entire hood frame must be covered with the hood sheet. The corresponding part under the floor is placed on the rising part of both sides with side shape U.
It is attached to a mold to form the lower hood sheet, and the upper edge of the hood body to the lower part of both sides is used as the upper hood sheet, and the ends of each hood sheet are overlapped to replace it in case of damage to the underfloor part. , we can respond to repairs and repairs. (6) Embodiment An embodiment of this invention will be explained with reference to the drawings.

This figure shows the deviation of the center line of the front and back head rivets due to crushing. 1 and 2, the upper canopy sheet 3 has a required number of rivets arranged at regular intervals in the width direction (vehicle direction) and spaced apart in the length direction (perpendicular to the longitudinal direction of the vehicle) of the canopy sheet. At the same time, the engaging body part 4 having the above-mentioned structure is constructed, and the engaging body part 4 connects the front side head rivet 4a and the back side rivet 4b by connecting the locking parts 4c, and this rivet head is attached to the hood bone. It is formed to be slightly larger than the width of the mounting groove of the rivet, and when the locking part 4c is slightly distorted and displaced due to the crushing of the rivet head, the engaging body part 4 clamps both the front and back surfaces of the hood sheet and strengthens it. It is clamped and fixed. Further, the intervals at which the engaging body parts 4 are installed in the longitudinal direction are appropriately determined within a range that allows them to be stretched and held in the mounting grooves of the canopy ribs described later. In particular, Fig. 1 2 shows the hood sheet 3.
The engaging body parts 4 arranged in rows spaced apart in the longitudinal direction are set in a pair of two rows in the middle of the hood sheet, and are cast inward at an angle α from the line connecting the straight parts. By driving the rivets so that they are distributed in a V-shape and bending the upper hood sheet 3 in the length direction along the engaging body part 4 , the bent tops are connected and the engaging body part 4 is bent according to the direction of the canopy bone nucleus. It can be configured so that it can be mounted in alignment with the mounting groove. Although the shape and dimensions of the front and back rivets 4a and 4b of the engaging body portion 4 formed on the surface of the hood sheet 3 are not particularly strictly defined, they are formed to be slightly larger than the mounting groove width so that they do not come out of the mounting groove 2. It is preferable that the head shape is round or round, and the material may be metal, synthetic resin, or the like. Furthermore, although the configuration of the upper hood sheet 3 has been described above, the lower hood sheet 5, which is divided and stretched over the hood ribs, is also constructed in the same manner as the upper hood sheet 3, as described later (Fig. 3). It can be used as Fig. 3 shows a connecting canopy with a known structure, and Fig. 1 is a side view showing a partially cut-off upper and lower hood sheet 3 and a lower hood sheet 5 attached to the hollow hood frame 1 at their joints l; FIG. 2 shows a known structure in which a part of the underfloor portion of the hood rib 1 is cut out and the opposing portions are joined by an elastic connector 6. A connected hood (front view) in which a seat attachment groove 2 is provided and a lower hood sheet 5 is attached to each of the attachment grooves. The present invention provides a connecting top for a vehicle as shown above, in which 1 is a top rib made of a hollow tube, and each of the top bones 1, 1 is
The wide upper hood sheet 3 in which the engaging body part 4 is installed is bent in the longitudinal direction along the mounting groove 2 which is continuous on the inner circumferential surface of the engaging body part 4, and the engaging body part 4 is attached to the mounting groove 2.
It is installed according to the In other words, FIG. 5 (the same left figure) is an explanatory diagram showing how the upper and lower side hood sheets 3 and 5 are attached to the hood ribs 1 and 2.
5 is applied to the mounting groove 2 and is bent longitudinally along the mounting groove 2 to expose the front head rivet 4a and the back head of the engaging body portion 4 to the inside and outside of the bent top surface of the bent portion. In the folded state in which the rivets 4b are connected to form an Ω-shaped protrusion on the bent side surface, the canopy sheet is pushed in from the end face of the canopy rib 1, and the repulsive force of the canopy itself acts to temporarily attach the canopy sheet to the attachment groove in a detachable manner. Then, the upper (lower) side hood sheets 3 and 5 facing each other at the opening of the mounting groove 2 are attached to the hood rib 1.
Each hood bone 1 extending continuously and adjacent to the outer sides of the

The engaging body part 4 near the folded top of the hood sheet also moves toward the mounting groove 2 side due to the tension, but at this time, the engaging body part 4 closes the mounting groove 2 and the engaging body part 4 and this engaging body Since the hood sheet is locked with the end edge portion of the mounting groove 2 by the bulge portion 3a of the hood sheet held by the hood, the hood sheet is held in the mounting groove 2 and prevented from coming off. has been completed. Figure 4 shows the rising portion of the lower hood 5 on both sides of the underfloor portion of the entire hood frame, which has a U-shaped side surface and overlaps the upper hood sheet 3, and the engaging body is attached to each hood frame of the hood frame via the mounting groove at the portion l. It is attached at part 4 . Further, even in the event of rain from the upper (lower) side hood sheet overlapping portion 1, since the lower hood sheet 5 overlaps the upper hood sheet 3 inwardly, water intrusion from this portion is prevented. Both ends of the upper (lower) side hood sheets 3 and 5 are connected to a hood mounting frame 7 connected to the vehicle 10, respectively, with a vault 8,
It is fastened and fixed with a nut 9. In the figure,

In addition, it can be attached to the attachment groove 2 of the canopy 1 by the engaging body part 4 of the facility by the same means as described above. Fig. 7 1 shows a partially cut-out side surface of the hood bones 1 assembled by connecting the upper and lower sides of each hollow hood bone alternately to form a V-shaped side surface, and 2 shows the same side view. Plan view of the upper side of the hood (ceiling) of No. 1, No. 9
The figure is a sectional view taken along the line a-a in FIG. 7 and 2, and shows an example of tensioning the upper hood sheet 3 in which the engaging body portion 4 is provided to the deformed hood bone nucleus. In addition, in the figure, 12 is a hinge joint fitting.
Further, FIG. 10 shows that an engaging body portion 4 is formed by front and back rivets 4a and 4b from both the front and back sides of the upper (lower) side hood sheets 3 and 5, and hood ribs 1 are attached in units of 2 to 3 to each hood. Known flexible engaging core materials 13, 13 are stretched over the bones and fixed to both widthwise ends of the wide hood sheet, and are attached to the hood rib 1. Such application is applicable to the upper and lower side hood sheets. It is effective if it is attached to the connecting hood in a particularly damaged and heavily soiled part, since it can be easily replaced and used. Next, FIG. 11 shows another embodiment of the present invention shown in FIGS. 1 and 2, in which an engaging body part 4 is installed, for example, on the top sheet 3. In arranging the required number of engaging body parts 4' in a row at intervals corresponding to the width direction of the sheet 3, that is, the maximum expansion distance between adjacent canopy bones, and spaced apart in the length direction,
The hood sheets 3 are bent in the direction of the arranged positions, and the vicinity of the folded tops 3' are overlapped, and a rivet is inserted orthogonally into the overlapped hood sheets, and the engaging body portions 4' are inserted therethrough. The left head rivet 4'a and the right head rivet 4'b are connected through the overlapping portion 3'a of the hood sheet.
are firmly clamped and fixed from both sides by connecting the locking parts 4'c, but in this case, the overlapping part 3'a of the hood sheet
The right and left head rivets 4'a and 4'b for clamping can be set by changing the clamping direction of the right and left head rivets 4'a and 4'b in the longitudinal direction as shown in Fig. 11 1 and 2. By doing so, the alignment of the engaging body portion 4 when attached to the hollow tube is improved, and the hood sheet can be attached neatly. Incidentally, the intervals at which the engaging body portions 4' are installed in the longitudinal direction may be appropriately determined within a range that can hold the stretched awning sheet. 3'' in the same figure is a bulging part , which is derived by tightening the overlapping part 3'a near the bent top 3' of the hood sheet 3 with the engaging body part 4'. 'a' is housed in the hollow tube together with the engaging body part 4' of the facility, so there is no problem as a hood body. Fig. 12 shows the state in which the hood sheet 3 of Figs. 11 and 2 is attached to the hollow tube. In this manner, when the hood sheet 3 is attached to the hood bone, the hood sheet 3 to be inserted into the hollow tube in a bent state is already formed as a bent body by the engagement body portion 4' , so that the hood sheet 3 is folded. It is possible to immediately insert the engaging body portion and efficiently attach it to the canopy bone 1 without manually performing a bending operation. The engaging body portion of the top sheet to be attached to the wide top sheet is constructed by integrally driving a rivet head in the longitudinal direction of the wide top sheet, and the engaging body portion is provided when the top sheet is attached to the top rib. The hood sheet is inserted into the hollow tube hood rib near the top of the bent part in the longitudinal direction while the hood sheet is folded in its longitudinal direction, and the engaging body part that clamps and fixes the hood sheet is engaged with the edge of the mounting groove to secure the hood sheet. (7) Effects of the Invention The present invention has the above-described structure and function, and is capable of attaching a wide hood sheet to the adjacent hood frame. Since the hood sheet is provided with an engaging body part by driving rivets in the direction of the mounting groove of the hood rib, the hood sheet can be placed in the direction in which the engaging body parts are connected. Since it is long enough to be inserted in a folded state, it can be quickly connected and installed between each canopy rib in one step, so it is possible to fuse and fix the engaging body as a molded material to the surface of one side of the canopy sheet as in the past. Alternatively, there is no need to prepare a separate molding material, and the installation work can be done much more labor-savingly.Therefore, there is no need for molds or fusion processing associated with the production of molding materials, resulting in a significant cost reduction. This is an effect that was not expected at all from Japanese Patent Publication No. 57-60176, Japanese Utility Model Publication No. 58-12262, and Japanese Patent Publication No. 58-2862.Furthermore, the hood sheet engaging body portion of the present invention has a riveted structure as described above. Depending on the design, the hood sheet can be used alone or the overlapping part of the folded top can be clamped and fixed with rivet heads, and these double-headed rivets engage the mounting grooves to lock the hood sheet.The construction is extremely simple and mass production is possible. Since it is not tied down during pouring, it can be folded for convenient transport and storage.In addition, it can be detachably attached to the canopy and can be easily replaced locally, saving labor and material costs. It has a remarkable effect on the production of connected canopies, as it has a remarkable effect on materials and labor.
