DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, crutches adjustable according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the present specification, the same or similar reference numerals are given to different embodiments in the same or similar configurations.

FIG. 1 is a perspective view showing an appearance of a crutch 100 that can be adjusted according to an embodiment of the present invention.

The crutch 100 may include an upper rod 110, a lower rod 120, a control module 130, and a non-slip unit 160.

The upper rod 110 is a member having a receiving space 112 whose one side is open. Specifically, the upper rod 110 may include a hollow cylinder portion 111 in which a receiving space 112 is formed, and a support portion 113 provided at an upper end of the cylinder portion 111. The supporting portion 113 is a portion to be fitted to the armpit of the crutch 100 and is arranged in a direction substantially perpendicular to the extending direction of the cylinder portion 111. The cylinder portion 111 is formed with an open slot 115 which is a portion linearly opened along the extending direction thereof.

The lower rod 120 is a member that is inserted into the accommodation space 112 through one open side of the upper rod 110. Accordingly, unlike the upper rod 110, the lower rod 120 need not be formed as a hollow body.

The adjustment module 130 is installed on the upper rod 110 to adjust the overall length of the crutch 100 together with the height of the knob 133. The adjustment module 130 may include a body 131, a first fixed unit 136, and a second fixed unit 137.

The body 131 may include a housing 131a, a bending member 132b, and a handle 133.

The housing 131a is formed as a hollow body so that the upper rod 110 can be slidably inserted into the hollow portion thereof. In this embodiment, the housing 131a is illustrated as having a hollow cylindrical shape corresponding to the shape of the cylinder portion 111. [ With this housing 131a, the adjustment module 130 allows the housing 131a to slide relative to the upper rod 110 without being separated from the upper rod 110. [ Thus, it is more convenient to position the adjustment module 130 relative to the upper rod 110. A fixing hole 134 corresponding to the first fixing unit 136 and a window 135 corresponding to the second fixing unit 137 are also formed in the housing 131a.

The bending member 132b is a member that connects the housing 131a and the handle 133. [ The folding member 132b is bent at least once in the housing 131a so that the handle 133 is parallel to the support portion 113. [ In the present embodiment, it is exemplified that the bending member 132b is bent twice.

The handle 133 is a portion held by a user who supports the armpit on the support portion 113 by hand. The handle 133 is a portion that a user of the crutch 100 exerts a force together with the support portion 113 and is required to be positioned at a different height according to a user's body condition separately from the support portion 113. [

The first fixed unit 136 is configured to detachably fix the body 131 to the upper rod 110. In this embodiment, the first fixing unit 136 is screwed into the fixing hole 134, and the end thereof is a fixing screw which presses the upper rod 110 through the fixing hole 134. The fact that the body 131 can be fixed to the upper rod 110 with the first fixed unit 136 means that the height of the knob 133 constituting a part of the body 131 can be adjusted as a result.

The second fixed unit 137 is a configuration that allows the upper rod 110 to be fixed at an arbitrary position with respect to the lower rod 120, and consequently to adjust the overall length of the crutch 100.

The second fixed unit 137 may include rod irregularities 138 and an operating member 139. [ The rod irregularities 138 are provided on the outer surface of the lower rod 120 so as to be arranged along the extending direction of the lower rod 120. The rod irregularities 138 extend in a bar shape, and the surface facing the open slot 115 is formed with irregularities. The operating member 139 is operatively installed on the body 131, specifically, the housing 132a, and is engaged with the projection of the rod irregularities 138 in a state. The upper rod 110 provided with the operating member 139 is connected to the lower rod 120 provided with the rod irregularities 138 by the engagement of the projection and the operating member 139, As shown in FIG.

The anti-slip unit 160 may be installed at the free end of the lower rod 120. [ The anti-slip unit 160 is provided to increase the frictional force between the crutch 100 and the ground. In this embodiment, a spike 165 is employed.

The internal construction of the crutch 100 will be described with reference to Fig.

2 is a partial cutaway perspective view for explaining the inside of the crutch 100 of FIG.

Referring to this figure, the operating member 139 of the second fixing unit 137 may include an operating portion 140 and an engaging portion 141. The operation unit 140 is a part exposed to the outside through the window 135 of the housing 132a and operated by the user. The engaging portion 141 is connected to the operating portion 140 and is engaged with or separated from the projection of the rod irregularities 138 in response to the operation of the operating portion 140. [ The second fixing unit 137 will be further described with reference to Fig.

Referring again to FIG. 2, the elastic body 150 may be disposed in the accommodation space 112. The elastic body 150 is, for example, a compression coil spring, one end of which is supported by the support portion 113 and the other end is supported by the lower rod 120. The elastic body 150 resiliently urges the lower rod 120 in a direction away from the accommodation space 112 so as to lengthen the entire length of the crutch 100. [ The second fixed unit 137 overcomes the elastic force of the elastic body 150 and fixes the lower rod 120 to the upper rod 110 in a fixed position. It will be more convenient to adjust the relative position of the lower rod 120 relative to the upper rod 110 before securing by the second securing unit 137 if the elastic body 150 is provided.

In order to facilitate the operation of the second fixed unit 137 and facilitate the user's convenience, the rod irregularities 138 are preferably in a state always corresponding to the open slots 115. [ For this purpose, an alignment unit 143 may be employed. The alignment unit 143 includes a key 144 protruding from the outer circumferential surface of the lower rod 120 and a rail 144 formed on the inner circumferential surface of the upper rod 110 to be slidably received therein 145). According to this alignment unit 143, the lower rod 120 is movable in the longitudinal direction relative to the upper rod 110, but does not rotate in the upper rod 110. Therefore, it is easy to initially set the state in which the rod irregularities 138 are aligned with respect to the open slot 115, and there is an advantage that the state remains unchanged.

The non-slip unit 160 may include an outer cylinder 161 and an inner cylinder 163. [ The outer cylinder 161 is a hollow member having a first screw thread 162 formed therein. The inner cylinder 163 is inserted into the hollow portion of the outer cylinder 161 and has a second screw thread 164 screwed to the first screw thread 162 on its outer surface. The spike 165 described above is also formed in the inner cylinder 163.

With such a configuration, the spike 165 is rotated in one direction to cause the spike 165 to come out of the outer cylinder 161, or the inner cylinder 163 to rotate in the other direction, It is possible to get inside. In the latter case, if the spike 165 is inserted into the outer cylinder 161 beyond the lower end of the outer cylinder 161, the spike 165 does not protrude to the outside, thereby preventing the occurrence of an accident caused by the spike 165 have.

In other words, in the other season, the spike 165 is introduced into the outer cylinder 161 to expose the spike 165 and the spike 165, The crutches 100 can be used while safely storing them in an unused state.

Next, the second fixing unit 137 will be described in detail with reference to FIG.

Figure 3 is an enlarged perspective view of a portion A of Figure 2;

Referring to this figure, the operating member 139 is pivotally mounted in the housing 132a in the pivoting direction S by a pivot pin 143 passing through the center portion thereof.

The operating member 139 includes an operating portion 140 exposed to the outside through the window 135 of the housing 132a and an engaging portion 141 engaged with the projection of the rod irregularities 138 as described above do. The turning pin 143 can be inserted into an area where the operating portion 140 and the engaging portion 141 meet.

The engaging portion 141 may include a pair of legs formed to surround both sides of the projection of the rod irregularities 138. The pair of legs may be one, but if it is a pair, the engagement can be further strengthened with respect to the rod irregularities 138.

A biasing member 143 may be provided to further strengthen the engagement of the engaging portion 141 with the bar irregularities 138. The biasing member 143 is, for example, a spring, one end of which is connected to the housing 132a and the other end is connected to the operating member 139. [ The biasing member 143 exerts a force for biasing the operating member 139 toward the bar irregularities 138 so that the engaging portion 141 strongly engages the protrusions of the bar irregularities 138. As a result,

A state in which the crutches 100 are variously adjusted according to the use environment will be described with reference to FIG.

4 is a perspective view showing various states of crutches 100;

4 (a) is a basic state described above based on Fig.

Referring to FIG. 4 (b), it can be seen that the overall length of crutches 100 is reduced compared to FIG. 4 (a). This is mainly due to the operation on the second fixed unit 137. [

The lower rod 120 can be pushed into the receiving space 112 of the upper rod 110 after the operation member 139 is disengaged from the rod irregularities 138. [ At this time, if the elastic body 150 is disposed in the receiving space 112, the elastic body 150 may be overcome the elastic force and press the upper rod 110.

After the lower rod 120 enters the accommodation space 112 of the upper rod 110, the operation member 139 is engaged with the rod irregularities 138 to connect the upper rod 110 and the lower rod 120 to each other . In this state, the crutch 100 can be safely stored in a vehicle or the like by reducing the overall length of the crutch 100.

When the inner cylinder 163 of the non-slip unit 160 is rotated in one direction so that the spike 165 is inserted into the outer cylinder 161, the size of the crutch 100 can be further reduced, State.

Referring to FIG. 4 (c), the overall length of the crutch 100 is the same as in (a), but the adjustment module 130 is closer to the support 113. This narrows the gap between the knob 133 and the support portion 113 of the adjustment module 130 so that the height of the knob 133 can be adjusted according to the length of the user's arm.

At this time, the operating member 139 is engaged with the protrusion of the upper portion rather than the bar protrusion 138 with respect to (a). Accordingly, in order to move the adjustment module 130 toward the support portion 113, first, the operation member 139 is operated to release the engagement between the engagement portion 141 and the bar irregularities 138, (113).

It is needless to say that the fixing by the first fixing unit 136 must first be released for the sliding of the adjusting module 130. [ After the adjustment module 130 is slid and moved, the operation member 139 is again engaged with the bar concavity 138 and the first fixing unit 136 is operated to move the upper rod 110 of the adjustment module 130, As shown in Fig.

The crutches which can be adjusted according to the use environment as described above are not limited to the configuration and the manner of operation of the embodiments described above. The above embodiments may be configured such that various modifications may be made by selectively combining all or part of the embodiments.
