Description

[Detailed description of the invention] Technical field to which the invention pertains This invention relates to a door support device for a traveling toy equipped with an openable/closable door.

Conventional technology and its disadvantages When installing a door that can be opened and closed on a traveling toy, the structure for maintaining the door in the open and closed state becomes complicated and the number of parts increases. Does not have a door. Therefore,
Conventional running toys have the disadvantage that they differ significantly from the structure of actual automobiles, look unrealistic, and lack a sense of realism.

Purpose of this invention In view of the above points, this invention uses a door support member and a door member, and links the door support member and door member with a click mechanism, so that the door can be opened with a minimum number of members. To provide a door support device for a traveling toy that can be maintained in both the open and closed states.

Embodiment of this invention Next, an embodiment of this invention will be described based on the drawings.

FIG. 1 is an external view of a traveling toy with a door attached by a door support device according to this invention, and FIG. 2 is an exploded perspective view of the traveling toy clearly showing each component.

Body 1 includes front, side and rear window portions 2
The point that a, 2b, and 2c are molded with synthetic resin in an open state is similar to the conventional method, but in this invention, in connection with installing a door that can be opened and closed, the lower side of the window portion 2b on both sides is A notch 3 is provided in the section to be opened and closed by a door described later. The rear end 29 of the fender faces the notch.

Reference numeral 4 denotes a window sealing member for closing and closing each of the window portions 2a to 2c, which is formed of synthetic resin into a hollow trapezoidal shape opening at the bottom, and has a window sealing member 4 at the front, side, and rear portions of the body, respectively. It has shielding surfaces 5a, 5b, and 5c for shielding. However, the front part of the side part is recessed inward to form a fingertip insertion recess 6 so that the door can be opened by inserting the fingertip into the side window part as described later.

The window sealing member 4 is fitted into the body roof portion 8 from the lower surface of the body 1, and a shaft 9 protruding from the lower surface of the roof of the body is inserted into a hole 7 provided at the center of the upper surface of the window sealing member. An E-ring r is fitted onto the shaft protruding downward from the hole 7, so that each window portion 2a-2c is shielded by each shielding surface 5a-5c, as shown in FIG.

Since the front part 1a and the rear part 1b of the body 1 are only connected by the pillars 10 of the roof part 8, there is a problem in terms of strength. In order to solve this problem, plate-shaped connecting parts 11a and 11b having holes at the front and rear parts of the window sealing member 4 are integrally formed, and the lower surface of the rear end of the front part 1a of the body and the front end of the rear part Small protrusions 12a and 12b are provided on the lower surface, respectively, and when the window sealing member 4 is fitted to the lower side of the body, the small protrusions 12a and 12b are fitted into the holes of the connecting parts 11a and 11b, and the small protrusions expand. It is fixedly connected by a carved tip.

13 is a door support member which is one of the two members constituting the main part of the door support device according to this invention, and 14 is the other door member. The door support member 13 is made of hard synthetic resin, and has a fulcrum 15 on the rear lower surface of the fender of the body 1 to which the tip of the arm of the door member is pivoted. Since the number of door support members required is equal to the number of left and right doors, it is also possible to use two separate members for the left and right doors, but in the preferred embodiment shown, in order to simplify installation, they are made into a single member and fixed. A boss hole 17 is provided at the center of the portion 16, into which a shaft 18 protruding from the front lower surface of the body is rotatably fitted, and support shafts 19 provided at both left and right ends of the fixed portion 16 are provided.
The door support member 13 is fixed by fitting into a hole 20 provided on the front lower surface of the body.

On the other hand, a pair of left and right door members 14 is required,
A 7-shaped arm portion 22 having a hole 21 at its tip and a door portion 14a connected to the other end of the arm portion.
It is made of hard synthetic resin. The arm portion 22 has the above-mentioned shape to form a cavity 23 that is open to the side, and has elasticity due to its material. The door member 14 is constructed by passing the support shaft 19 of the door support member 13 through the hole 21 at the tip of the arm before fitting it into the hole 20 of the body, and then fitting the support shaft 19 into the hole 20. A member 14 is rotatably supported around a support shaft 19.

Reference numeral 24 denotes a chassis that is almost similar to the chassis used in conventional traveling toys, and after attaching a spring-type drive body and wheels (not shown) to the upper surface of this chassis, the door support member 13 is attached as described above.
The body 1 with the door member 14 attached thereto is covered from above the chassis, and the locking piece 25 provided at the rear of the body is connected to a hole 26 formed at the rear of the chassis.
At the same time, a screw (not shown) is screwed into the shaft 18 of the body through a hole 27 provided at the front of the chassis to connect the body and the chassis to complete the traveling toy.

Reference numeral 28 denotes a shielding plate that prevents the color of the driving body from being directly visible to the outside and spoiling the appearance when the door portion 14a is opened.

When the door member 14 is installed in this manner and the door is closed, the upper part of the door protrudes slightly above the bottom surface of the recess 6 of the window sealing member.
I find it easy to hang my fingertips on that door.

Due to the above-mentioned structure of the door member, when the door part 14a is closed, as shown in FIG. 29 and closes the notch 3. The two smooth surfaces 22c and 22d facing the air 23 between the free side tip 22a and the base side bent portion 22b of the arm portion 22 are continuous at an obtuse angle, and are respectively separated from the center of the support shaft 19. From the tip 22a of the arm to the shortest point 30 of the first smooth surface 22c of the arm, the first smooth surface 22c and the second smooth surface 2
2d, the shortest point 32 of the second smooth surface 22d, and the terminal end 33 of the second smooth surface are defined as l ₁ to _{l 5} , respectively, and the distance from the center of the support shaft 19 to the rear end of the fender is If the distance is l _f , then the relationships are as follows: l _f = l ₁ = l ₃ = l ₅ , l ₂ = l ₄ , l ₁ , l ₃ , l ₅ >l ₂ , l ₄ . In addition, the arm portion 22 has elasticity as described above.

Therefore, when the fingertip is inserted into the recess 6 and the closed door portion 14a is pulled outward, the arm portion 22
is elastically deformed, and as shown in FIG. Then, the rear end portion 29 of the fender enters the space 23 of the door member, but due to the above distance relationship, the rear end portion of the fender enters the shortest point 3 of the first smooth surface.
0 and fits into the intersection line 31 or the second
When the arm portion passes through the shortest point 32 of the smooth surface and reaches the terminal end 33, the arm portion elastically returns to its original position, so that it is stabilized and stopped at that position. In other words, the arm portion 22 and the rear end of the fender constitute a click mechanism, and the door is stopped at either of the two door opening angles shown in FIG.
Stay open.

When the door part 23 is rotated in the opposite direction to a position where the notch 3 is covered, the door is closed again and the closed state is maintained.

This invention is not limited to the above-described configuration in the coupling structure between the door support member 13 and the door member. That is, the objects in which the support shaft 19 and the hole 21 are provided may be reversed, and the structure for fixing the door member to the body may be arbitrary.

Effects of this invention As mentioned above, in the door support device according to this invention, the arm of the door member has two continuous smooth surfaces at an obtuse angle, and the vertical distance from the pivot point to each smooth surface is Since they are made equal, when the door member is opened, the rear of the fender will be the empty part of the arm.
Since it is elastically locked at the shortest distance from the pivot point of each smooth surface, the opened door can be stopped at two angles.
