A support protrusion (33) is provided inside the frame (3) and is inserted into the lower inner wall of the positioning protrusion (41), and a support shaft (34) is provided at the center of the frame (3). Is provided. The support protrusion (33) and the support shaft (34) prevent the upper plate (4) from partially bending downward.

Support recesses (42) are opened in front and rear portions of both side surfaces of the upper plate (4), and a lock device (5) is hinged therein, and a frame (3) is attached to the frame (3). Support recess (4
A support rise (35) is formed to support both side walls of 2).

The locking device (5) comprises a support recess (4
The hinge (52) with which the pin (51) fixed to 2) engages,
Limit plate (53) protruding inward from the lower edge of the hinge (52)
And an engaging projection (54) that is bent from the outer top of the limiting plate (53) and is fixedly inserted into the engaging recess (12) of the front bottom (11). In the assembled state, the locking device (5) can rotate around the pin (51) within a predetermined angle.

The locking means (6) consists of one selection lever (6A)
And two operation links (6B) and two sliders (6C). The configuration of these parts will be described with reference to FIGS.

The selection lever (6A) is rotatably engaged with the support shaft (34) by a central fixing portion (61), and on the lateral side of the fixing portion (61), an arcuate slot (36) is provided. A handle (62) is provided extending therethrough toward the outer lower surface. A connecting shaft (63) is provided at the front and rear of the fixed portion (61). With such a structure, when the handle (62) is operated along the arcuate slot (36), both connecting shafts (63) rotate about the fixed portion (16).

Next, the operation link (6B) has one end
It has a connecting portion (64) corresponding to the connecting shaft (63), and at the other end has a link shaft (65) seated in the guide groove (37) of the frame (3). . When the selection lever (6A) is operated, the link shaft (65) linearly slides along the guide groove (37).

Finally, the slider (6C) is connected to the operation link (6C
It has a connecting part (66) to which the link shaft (65) of (B) is connected, so that the slider (6C) moves linearly in association with the movement of the operation link (6B). Has become. A dovetail (43) is provided on the lower surface of the upper plate (4) to guide the linear movement of the slider (6C), and a corresponding dovetail groove (67) is provided on the upper surface of the slider (6C). . Slider (6
C) slides to engage or disengage the locking device (5). In the engaged position, the slider (6C) is located on the limiting plate (53) of the locking device (5), and in the released position, the slider (6C) is retracted from above the limiting plate (53). There is. Therefore, the lock device (5) is transferred from the engagement position where rotation is blocked to the release position where rotation is possible and vice versa.

The skate body (2) of the roller skates (R) described above can be removed from the shoes (1) while the user wears the shoes. The attaching operation is the reverse of the removing operation. Therefore, the process of removing the skate body (2) from the shoe (1) will be described below.

As shown in FIG. 1, the skate body (2) has front and bottom engaging projections (54) on both side surfaces of the upper plate (4).
It is prevented from coming off the shoe (1) by being locked in the engaging recess (12) of (11). Figure 5a also shows the engaged state
(Locking device (5) is locked). Since the positioning recess (13) of the upper plate (4) and the corresponding positioning projection (41) of the outsole (11) of the shoe are engaged with each other, the shoe (1) and the skate body (2) are It is reliably prevented from sliding horizontally and separating. The vertical separation of the shoe (1) and skate body (2) is also prevented by the four locking devices (5).

However, since roller skating is considered to be an entertainment of intense activity, the skating body (2) and shoes (1)
The possibility of separation from should not be completely ruled out. In view of the above points, the material for the outsole (11) of the shoe preferably has high tensile strength, compressive strength and abrasion resistance together with appropriate elasticity. These properties are especially required for the shoe (1) removed from the skate body (2) to be used as a normal shoe.

On the other hand, in the attached state, the slider (6C)
Is located on the limiting plate (53) of the locking device (5), and the engaging protrusion
The rotation of (54) is restricted by the restriction plate (53). Fig. 3 shows the locking device (5) in the locked state when the upper plate
It is shown in a plan view with (4) removed. At this time,
The selection lever (6A) of the locking means (6) is arranged so that the end of the handle (62) is in the lock position (C) of the operation groove (26), that is, the handle has an operation slot (6) as shown in FIG. It is located at the right end of 36), facing downward and exposed. In this position,
The connecting shaft (63) and the operating link (6B) are aligned in the longitudinal direction of the shoe, and the slider (6C) is maintained in the engaged state.

To remove the skate body (2) from the shoe (1),
The user must push the handle (62) of the selection lever (6A) into the unlocked position (O) of the arcuate operation slot (36). Then, the selection lever (6A) rotates around the axis of the support shaft (34) toward the position shown in FIG. Finally, the connecting shaft (63) of the selection lever (6A) is arranged approximately at right angles to the longitudinal axis (CL) of the shoe. By the above operation, the operation link (6
The connecting part (64) of B) is moved together with the connecting shaft (63), and the link shaft (65) is also moved toward the supporting shaft (34). The slider (6c) slides on the dovetail groove (67) and the dovetail (43) of the upper plate (4) by the integral operation of the selection lever (6A) and the operation link (6B). FIG. 5b shows the slider (6C) removed from the locking device (5). Therefore, the restriction on the restricting plate (53) of the lock device (5) is released, and the engaging projection (54) integrated with the restricting plate (53) becomes the supporting recess of the upper plate (4).
The pin (51), which is supported by (42), is rotated around the axis of the pin (51) to some extent. Rotation of locking device (5) is locking device (5)
Means that the engaging projection (54) is retracted from the engaging recess (12) so that the shoe (1) can be removed from the skate body (2).

The removed shoe can be used as a normal shoe as described above. And by replacing the shoes with one of a different size, even if the young user grows up and cannot wear the original shoes, the skate body (2) can be used for a long time and the skate body is damaged. Otherwise, a few users with different shoe sizes can use the same skate body. For these purposes, the relative position of the engaging recess (12) and the positioning recess (13) of the outsole (11) with respect to the positioning projection (41) of the upper plate (4) and the locking device (5), The distances are preferably equal, regardless of shoe size.

In another embodiment, of the two pairs of locking devices (5), only one locking device (5), for example
The pair of (or front) sides or the pair of right (or left) locking devices may be hinge-type locking devices, and another pair of locking devices may be fixed to the skate body (2).
These fixed locking devices are attached to the shoe (1) by sliding.

[0031]

As described above, the present invention provides the skate body.
Since the (2) can be easily removed from the shoe (1), convenience and usability can be improved and injury can be prevented. According to the present invention, shoes of various sizes can be attached to one skate body, so that the roller skates having a relatively simple structure can save money and extend the usable period.
