Description

[Technical Field]

[0001] The present disclosure relates to a wheelchair securing mechanism. [Background technology]

[0002] BACKGROUND ART A mechanism using a striker and a latch is known for fixing a wheelchair to the floor or the like in a vehicle such as an automobile (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 8-150176 Summary of the Invention [Problem to be solved by the invention]

[0004] In conventional locking mechanisms using a striker and a latch, the wheelchair cannot be secured if the striker and latch are misaligned, so accurate alignment is necessary. Furthermore, it is difficult to align the striker or latch when they are not visible.

[0005] One aspect of the present disclosure aims to provide a wheelchair securing mechanism that facilitates alignment of the striker and the latch. [Means for solving the problem]

[0006] One aspect of the present disclosure is a wheelchair fixing mechanism (1) that fixes a wheelchair (102) to a fixing part (101) installed in a vehicle. The wheelchair fixing mechanism (1) includes an engaged part (2) provided on a first member, either the wheelchair (102) or the fixing part (101), and an engaging part (3) provided on the remaining second member, either the wheelchair (102) or the fixing part (101). The engaged part (2) has at least one rod-shaped striker (21A) extending in the vertical direction.

[0007] The engagement portion (3) has at least one accommodating portion (31A) configured to accommodate at least one striker (21A), at least one latch (32A) configured to restrict detachment of the at least one striker (21A) from the at least one accommodating portion (31A), and at least one guide portion (33A) configured to guide the striker (21A) toward the at least one accommodating portion (31A).

[0008] At least one guide portion (33A) has a first guide surface (331) and a second guide surface (332) that face each other in the width direction of the wheelchair (102) fixed to the fixing portion (101) and whose distance from each other decreases toward the at least one storage portion (31A).

[0009] According to this configuration, the striker (21A) is guided by the first guide surface (331) and the second guide surface (332) of the guide portion (33A) toward the accommodation portion (31A), which is the fixed position, when the engaged portion (2) engages with the engaging portion (3). This facilitates alignment of the striker (21A) with the latch (32A).

[0010] In one aspect of the present disclosure, the engaged portion (2) may have, as the at least one striker (21A), a plurality of strikers (21A, 21B) arranged apart from each other in the width direction. The engaging portion (3) may have, as the at least one receiving portion (31A), at least one latch (32A), and at least one guide portion (33A), a plurality of receiving portions (31A, 31B), a plurality of latches (32A, 32B), and a plurality of guide portions (33A, 33B). This configuration improves the stability of the wheelchair (102) in the fixed state.

[0011] In one aspect of the present disclosure, the engagement portion (3) may include a base (35) provided with at least one storage portion (31A) and at least one guide portion (33A), and a position adjustment mechanism (36) configured to bias the base (35) toward the center in the width direction and to hold the base (35) movably in the width direction. With this configuration, misalignment between the striker (21A) and the latch (32A) in the width direction of the wheelchair (102) can be absorbed by the movement of the base (35) in the width direction. As a result, it is easier to align the striker (21A) and the latch (32A).

[0012] In one aspect of the present disclosure, the engaged portion (2) may have bumpers (22A, 22B) disposed widthwise outward of the at least one striker (21A). The length of the base (35) in the width direction may increase along the direction in which the at least one striker (21A) is inserted into the at least one storage portion (31A). With this configuration, when the engaged portion (2) and the engaging portion (3) engage with each other, the end of the base (35) in the width direction of the wheelchair (102) comes into contact with the bumpers (22A, 22B), thereby adjusting the position of the base (35). As a result, it is easier to align the striker (21A) and the latch (32A).

[0013] In one aspect of the present disclosure, the engaged portion (2) may be provided on the fixed portion (101). The engaging portion (3) may be provided on the wheelchair (102). With this configuration, an operating portion for unlocking the latch (32A) can be provided on the wheelchair (102). Therefore, a person seated in the wheelchair (102) can unlock the latch (32A).

[0014] In one aspect of the present disclosure, the fixing part (101) may be a vehicle seat (101). With this configuration, the wheelchair (102) and the vehicle seat (101) can be integrated. Therefore, the seat belt of the vehicle seat (101) can be used by the occupant of the wheelchair (102).

[0015] Note that the symbols in the parentheses above are examples showing the correspondence with the specific configurations, etc. described in the embodiments described below, and the present disclosure is not limited to the specific configurations, etc. shown by the symbols in the parentheses above.

[0017] Hereinafter, embodiments to which the present disclosure is applied will be described with reference to the drawings. [1. First embodiment] [1-1.Configuration] 1 is a mechanism for fixing a wheelchair 102 to a vehicle seat 101 installed in a vehicle. The wheelchair fixing mechanism 1 is composed of an engaged part 2 and an engaging part 3.

[0018] Examples of vehicles on which the vehicle seat 101 may be installed include automobiles, railroad cars, ships, and aircraft. In addition, the directions in the following description and in the drawings refer to directions in the vehicle seat 101. The front-to-rear direction, width direction, and up-to-down direction of the wheelchair 102 fixed to the vehicle seat 101 respectively coincide with the front-to-rear direction, width direction, and up-to-down direction of the vehicle seat 101.

[0019] <Vehicle seats> The vehicle seat 101 is used as a seat for the vehicle and also functions as a fixing part for fixing the wheelchair 102.

[0020] As shown in FIG. 2, the vehicle seat 101 includes a seat cushion 101A, a seat back 101B, a first leg 101C, a second leg 101D, a seat belt 101E (see FIG. 1), a belt buckle 101F, and an engaged portion 2.

[0021] The seat cushion 101A is a portion that supports the buttocks of an occupant of the vehicle seat 101. The seat back 101B is a portion that supports the back of an occupant of the vehicle seat 101. As shown in FIG. 2, the seat cushion 101A is flipped up when the wheelchair 102 is fixed. In other words, the seat cushion 101A is configured to swing between a seatable position and a flipped-up position.

[0022] The first leg 101C and the second leg 101D support the seat cushion 101A and the seat back 101B. The first leg 101C and the second leg 101D are spaced apart from each other in the width direction.

[0023] The first leg 101C is disposed on the left side of the second leg 101D. The first leg 101C and the second leg 101D are attached to a slide mechanism 103 that is installed on the floor of the vehicle.

[0024] The slide mechanism 103 is configured to slide the vehicle seat 101 in the front-to-rear direction. The slide mechanism 103 has a first rail 103A and a second rail 103B that are spaced apart from each other in the width direction of the vehicle seat 101. The first leg 101C is slidably held by the first rail 103A. The second leg 101D is slidably held by the second rail 103B.

[0025] 1 is held by a seat back 101B. The seat belt 101E has a plate that can be attached to and detached from a belt buckle 101F that is disposed on the outer side of a seat cushion 101A in the width direction.

[0026] The seat belt 101E is stretched from one shoulder of the seat back 101B to the belt buckle 101F, and is worn by the occupant of the vehicle seat 101. When the wheelchair 102 is fixed to the vehicle seat 101, the occupant of the wheelchair 102 can also wear the seat belt 101E.

[0027] <Engaged part> 3, the engaged portion 2 is provided below the seat cushion 101A and the seat back 101B of the vehicle seat 101. The engaged portion 2 has a first striker 21A, a second striker 21B, a first bumper 22A, a second bumper 22B, a base 23, and a support beam 24.

[0028] The first striker 21A and the second striker 21B are each a rod-shaped member extending in the vertical direction, and are arranged apart from each other in the width direction of the wheelchair 102 fixed to the vehicle seat 101 (i.e., the width direction of the vehicle seat 101).

[0029] The first striker 21A is disposed to the left of the second striker 21B. The first striker 21A and the second striker 21B are disposed so as to overlap in the width direction of the vehicle seat 101. In other words, the first striker 21A and the second striker 21B are positioned at the same position in the front-rear direction of the vehicle seat 101.

[0030] Furthermore, the first striker 21A and the second striker 21B are disposed between the first leg 101C and the second leg 101D in the width direction of the vehicle seat 101. The distance between the first leg 101C and the first striker 21A is the same as the distance between the second leg 101D and the second striker 21B.

[0031] The first bumper 22A and the second bumper 22B are disposed outward in the width direction from the first striker 21A and the second striker 21B. Specifically, the first bumper 22A is disposed to the left and forward of the first striker 21A. The second bumper 22B is disposed to the right and forward of the second striker 21B.

[0032] The first bumper 22A is a curved plate-like member fixed to the front end of the first leg 101C. The first bumper 22A is disposed across from the front end surface of the first leg 101C to the right surface of the first leg 101C (i.e., the surface facing the second bumper 22B).

[0033] The second bumper 22B is a curved plate-like member fixed to the front end of the second leg 101D. The second bumper 22B is disposed across from the front end surface of the second leg 101D to the left surface of the second leg 101D (i.e., the surface facing the first bumper 22A).

[0034] The base 23 supports the lower ends of the first striker 21A and the second striker 21B. The base 23 connects the first leg 101C and the second leg 101D in the width direction. The upper surface of the base 23 is curved so that the angle of inclination with respect to the horizontal direction decreases toward the rear. In other words, the base 23 has a guide surface that guides the engagement portion 3 upward.

[0035] The support beam 24 holds the upper ends of the first striker 21A and the second striker 21B. The support beam 24 is located above the base 23 and connects the first leg 101C and the second leg 101D in the width direction.

[0036] <Wheelchair> As shown in FIG. 4, the wheelchair 102 has a seat 102A, a first wheel 102B, a second wheel 102C, and an engaging portion 3.

[0037] The first wheel 102B and the second wheel 102C are each rotatably attached to the seat 102A. The first wheel 102B is located to the left of the second wheel 102C. The seat 102A, the first wheel 102B, and the second wheel 102C are those of a known wheelchair. The wheelchair 102 can move in the forward and backward directions of the seat 102A.

[0038] <Engagement part> As shown in Fig. 5, the engagement portion 3 has a first storage portion 31A, a second storage portion 31B, a first latch 32A, a second latch 32B, a first guide portion 33A, a second guide portion 33B, a base 35, a position adjustment mechanism 36, and a release lever 37 (see Fig. 4). Fig. 5 is a schematic diagram of the wheelchair 102 as viewed from the bottom.

[0039] The first accommodating portion 31A is a recess configured to accommodate the first striker 21A. The second accommodating portion 31B is a recess configured to accommodate the second striker 21B. The first accommodating portion 31A and the second accommodating portion 31B each have a C-shape with an opening at the rear when viewed from above. The first striker 21A or the second striker 21B is inserted into the first accommodating portion 31A or the second striker 21B from the rear.

[0040] The first latch 32A is configured to restrict the removal of the first striker 21A from the first storage portion 31A. As shown in Figures 6 and 7, the first latch 32A is configured to be displaceable between a locked position where the first striker 21A is restricted from moving rearward by closing the opening of the first storage portion 31A, and an unlocked position where the first storage portion 31A is opened. Note that Figure 6 is a plan view in which a portion of the seat 102A of the wheelchair 102 is not shown.

[0041] When a load is applied from behind, the first latch 32A, which is in the locked position, moves to the unlocked position. The first latch 32A is biased from the unlocked position toward the locked position by an elastic body (not shown).

[0042] As the wheelchair 102 moves backward toward the vehicle seat 101, the first striker 21A collides from the front with the first latch 32A, which is in the locked position. This causes the first latch 32A to move to the unlocked position and the first striker 21A to be accommodated in the first accommodating portion 31A. When the first striker 21A is accommodated in the first accommodating portion 31A and the load on the first latch 32A is released, the first latch 32A moves to the locked position due to the biasing force. This locks the first striker 21A.

[0043] The second latch 32B is configured to prevent the second striker 21B from being removed from the second accommodating portion 31B. The configuration of the second latch 32B is the same as that of the first latch 32A. In other words, the second latch 32B moves from the locked position to the unlocked position upon collision with the second striker 21B, and is also biased from the unlocked position toward the locked position.

[0044] By moving the wheelchair 102 backward from the front of the vehicle seat 101 toward the vehicle seat 101, the first striker 21A and the second striker 21B are accommodated in the first accommodation portion 31A or the second accommodation portion 31B, and are held by the first latch 32A and the second latch 32B. As a result, the engaging portion 3 is fixed to the engaged portion 2.

[0045] The first latch 32A and the second latch 32B are connected to the release lever 37 shown in Fig. 4 by a wire 321 shown in Fig. 6. By operating the release lever 37, the first latch 32A and the second latch 32B are displaced from the locked position to the unlocked position.

[0046] When a seated person in a wheelchair 102 secured to the vehicle seat 101 operates the release lever 37 and moves the wheelchair 102 forward, the wheelchair 102 is detached from the vehicle seat 101. When the input to the release lever 37 is released, the first latch 32A and the second latch 32B are returned to the locked position by the biasing force.

[0047] The first guide portion 33A is configured to guide the first striker 21A toward the first accommodating portion 31A. The first guide portion 33A is provided rearward of the first accommodating portion 31A and continuous with the first accommodating portion 31A.

[0048] The first guide portion 33A has a first guide surface 331 and a second guide surface 332 that face each other in the width direction and whose distance decreases toward the first storage portion 31A. The first guide surface 331 and the second guide surface 332 define a passage path for the first striker 21A.

[0049] The first guide surface 331 and the second guide surface 332 are parallel to the up-down direction. The first guide surface 331 of the first guide portion 33A is located to the left of the second guide surface 332 and extends left rear from the first storage portion 31A. The second guide surface 332 extends right rear from the first storage portion 31A.

[0050] The first latch 32A is disposed in the first guide portion 33A. When the first latch 32A is in the locked position, it spans from the first guide surface 331 to the second guide surface 332. The first latch 32A is displaced from the locked position to the unlocked position by swinging in a direction away from the first guide surface 331.

[0051] The second guide portion 33B is configured to guide the second striker 21B toward the second accommodating portion 31B. The second guide portion 33B is provided rearward of the second accommodating portion 31B and continuous with the second accommodating portion 31B.

[0052] The second guide portion 33B has a shape symmetrical to the first guide portion 33A with respect to the center line in the width direction of the wheelchair 102. That is, the second guide portion 33B has a first guide surface 331 and a second guide surface 332 that face each other in the width direction and whose distance decreases toward the second storage portion 31B. In addition, the second guide portion 33B is provided with a second latch 32B.

[0053] The base 35 is held by the seat 102A and is disposed between the first wheel 102B and the second wheel 102C in the width direction. As shown in FIG. 5, the base 35 has a cover 351 and a support plate 352.

[0054] The cover 351 is a member that houses the operating mechanisms of the first latch 32A and the second latch 32B. That is, the first latch 32A and the second latch 32B are held by the base 35. The rear end of the cover 351 is provided with a first housing portion 31A, a second housing portion 31B, a first guide portion 33A, and a second guide portion 33B.

[0055] The widthwise length of the cover 351 (i.e., the left-right length) increases along the insertion direction of the first striker 21A and the second striker 21B into the first accommodating portion 31A or the second accommodating portion 31B (i.e., toward the front).

[0056] Specifically, the left end of the rear end of the cover 351 (i.e., the left side of the first storage section 31A) is provided with a first collision surface 351A that is parallel to the vertical direction and inclined so that the distance from the widthwise center line C of the wheelchair 102 decreases toward the rear.

[0057] In addition, a second collision surface 351B is provided at the right end of the rear end of the cover 351 (i.e., on the right side of the second storage section 31B), which is parallel to the vertical direction and inclined so that the distance from the widthwise center line C of the wheelchair 102 decreases toward the rear.

[0058] The first collision surface 351A is a portion that collides with or slides against the first bumper 22A of the vehicle seat 101 when the engaging portion 3 moves toward the engaged portion 2. The second collision surface 351B is a portion that collides with or slides against the second bumper 22B of the vehicle seat 101 when the engaging portion 3 moves toward the engaged portion 2. The base 35 is inserted into the lower part of the vehicle seat 101 from the front when the engaging portion 3 engages with the engaged portion 2 (i.e., when the wheelchair 102 is fixed to the vehicle seat 101).

[0059] 7, the first collision surface 351A and the second collision surface 351B are provided with a plurality of ridges 351C arranged in a vertical direction. Some of the ridges 351C extend from the first collision surface 351A or the second collision surface 351B to the front end surface of the cover 351.

[0060] 5 is fixed to the cover 351 from below. The support plate 352, together with the cover 351, vertically sandwiches the frame 361 of the position adjustment mechanism 36. The width of the support plate 352 is smaller than that of the cover 351. The rear end of the support plate 352 is located forward of the rear end of the cover 351.

[0061] The position adjustment mechanism 36 is configured to bias the base 35 toward the widthwise center of the wheelchair 102 and to hold the base 35 movably in the widthwise direction. The position adjustment mechanism 36 has a frame 361, a first spring 362, and a second spring 363.

[0062] The frame 361 extends in the width direction of the seat 102A and is fixed to the seat 102A, and supports the base 35 so that the base 35 is movable in the width direction.

[0063] One end of the first spring 362 is attached to the left side of the center in the width direction of the base 35, and the other end is attached to the sheet 102A. One end of the second spring 363 is attached to the right side of the center in the width direction of the base 35, and the other end is attached to the sheet 102A.

[0064] The first spring 362 and the second spring 363 bias the base 35 toward an initial position set at the center in the width direction. When the base 35 collides with the first bumper 22A and moves to the right, the first spring 362 expands and the second spring 363 compresses. As a result, a biasing force in the left direction is generated in the base 35. Conversely, when the base 35 collides with the second bumper 22B and moves to the left, the first spring 362 compresses and the second spring 363 expands. As a result, a biasing force in the right direction is generated in the base 35.

[0065] [1-2.Effects] According to the embodiment described above in detail, the following effects can be obtained. (1a) The first guide surface 331 and the second guide surface 332 of the first guide portion 33A and the second guide portion 33B, respectively, guide the first striker 21A and the second striker 21B toward the first accommodating portion 31A or the second accommodating portion 31B, which are fixed positions, when the engaged portion 2 engages with the engaging portion 3. This makes it easy to align the first striker 21A with the first latch 32A and the second striker 21B with the second latch 32B.

[0066] (1b) The first striker 21A and the second striker 21B are respectively held by the first storage portion 31A and the first latch 32A, or the second storage portion 31B and the second latch 32B, thereby improving the stability of the wheelchair 102 in its fixed state.

[0067] (1c) The position adjustment mechanism 36 can absorb misalignment between the first striker 21A and the second striker 21B and the first latch 32A or the second latch 32B in the width direction of the wheelchair 102 by moving the base 35 in the width direction. As a result, it becomes easier to align the first striker 21A and the first latch 32A, and the second striker 21B and the second latch 32B.

[0068] (1d) When the engaged portion 2 and the engaging portion 3 are engaged, the end of the base 35 in the width direction of the wheelchair 102 comes into contact with the first bumper 22A or the second bumper 22B, thereby adjusting the position of the base 35. As a result, it becomes easier to align the first striker 21A with the first latch 32A and the second striker 21B with the second latch 32B.

[0069] (1e) By providing the engaged portion 2 on the vehicle seat 101 and the engaging portion 3 on the wheelchair 102, an operating portion for unlocking the first latch 32A and the second latch 32B can be provided on the wheelchair 102. Therefore, the occupant of the wheelchair 102 can unlock the first latch 32A and the second latch 32B.

[0070] (1f) The fixed part of the wheelchair 102 is the vehicle seat 101, so that the wheelchair 102 and the vehicle seat 101 can be integrated. Therefore, the seat belt 101E of the vehicle seat 101 can be used by the seated person in the wheelchair 102.
