[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-146421 Summary of the Invention [Problem to be solved by the invention]
[0004] However, when wearing socks such as those described in Patent Document 1 with hard shoes such as leather shoes, business shoes, or men's shoes, parts of the shoes may come into strong contact with the foot, causing strong friction and resulting in blisters. Therefore, socks for use with these types of shoes are required to reduce friction and prevent blisters. [Means for solving the problem]
[0005] The sock that solves the above problem comprises a foot section extending from the toe to the heel, and a body section extending from the heel to the opening, and further comprises a first pile section made of terry knitting and having a length of at least 25% of the instep length, which is the length from the tip of the toe to an extension of the gore line of the heel, in an area between 15% and 90% from the toe, a support section with rubber knitted around the entire circumference of the foot section, which is located on the first pile section in an area closer to the gore line, and a second pile section made of terry knitting in an area including the heel, ankle, and ankle.
[0006] According to the above configuration, the first pile section is provided in a region of the upper between 15% and 90% of the instep height from the toe. The first pile section therefore reduces friction with the instep. The support section prevents the first pile section from shifting position, making it less likely for the first pile section to shift from areas prone to blisters. The second pile section also reduces friction between the shoe opening and the ankle and ankle. This reduces the occurrence of blisters.
[0007] In the above sock, it is preferable that the length of the support portion is 5% to 45% of the instep length. In the above sock, it is preferable that the second pile portion is provided so that the length from the apex of the heel portion to the body length, which is the length of the body portion, is in the range including 20% to 70%.
[0008] In the above sock, the first pile portion is preferably provided in a range of 40% to 60% from the edge of the instep side of the foot width of the foot portion when laid flat. In the above sock, the second pile portion is preferably provided at a position where it comes into contact with the tongue of the shoe.
[0009] In the above sock, it is preferable that the support part is a first support part, and that a second support part is provided in which rubber is knitted around the entire circumference of the opening part of the body part. In the above-mentioned sock, it is preferable that the body length, which is the length of the body part, is the same as or longer than the foot length, which is the length of the foot part. [Effects of the Invention]
[0010] According to the present invention, the occurrence of blisters can be suppressed. [Brief explanation of the drawings]
[0011] [Figure 1] 1A and 1B are diagrams illustrating the configuration of an embodiment of a sock laid flat. [Figure 2] 3 is a three-dimensional view showing a state in which the sock of the embodiment is worn on a foot and leather shoes are worn. FIG. DETAILED DESCRIPTION OF THE INVENTION
[0012] (Present embodiment) An embodiment of socks will be described below with reference to Figures 1 and 2. The socks of this embodiment are socks for business use.
[0013] (1 sock) As shown in FIG. 1, sock 1 comprises a foot section 4 extending from toe section 2 to heel section 3, and a body section 6 extending from heel section 3 to opening section 5. FIG. 1 shows sock 1 laid flat, and the following description will be based on this state. Sock 1 is characterized in that the body length LB, which is the length of body section 6, is longer than the foot length LF, which is the length of foot section 4. Sock 1 is a business sock, and differs from sports socks in which the body length LB is shorter than the foot length LF. The yarn used for sock 1 is preferably 32 count. Leather shoes for business use are harder than sports shoes. For this reason, it is preferable to wear sock 1 when wearing leather shoes to prevent blisters.
[0014] The sock 1 comprises a first pile section P1, a second pile section P2, a first support section S1, and a second support section S2. The first pile section P1 and the second pile section P2 are sections made of terry knitting. The terry knitting is only visible on the inner side of the sock 1 and is difficult to see from the outer side of the sock 1. In FIG. 1, the first pile section P1 and the second pile section P2 are indicated by diagonal lines for ease of understanding. The length from the tip of the toe section 2 to the extension of the gore line GL at the heel section 3 is defined as the instep length LT.
[0015] The first pile section P1 is provided in a region where the length LPA from the tip of the toe section 2 of the instep length LT is between 15% or more and 90% or less. Preferably, the first pile section P1 is provided in a region where the length LPA from the toe section 2 of the instep length LT is between 25% or more and 80% or less. More preferably, the first pile section P1 is provided in a region where the length LPA from the toe section 2 of the instep length LT is between 35% or more and 70% or less. The length LP1 of the first pile section P1 is 65% or more of the instep length LT. Preferably, the length LP1 of the first pile section P1 is 45% or more of the instep length LT. More preferably, the length LP1 of the first pile section P1 is 25% or more of the instep length LT. The length LP1 of the first pile section P1 is 75% or less of the instep length LT. Preferably, the length LP1 of the first pile section P1 is 55% or less of the instep length LT. More preferably, the length LP1 of the first pile section P1 is 35% or less of the instep length LT. If the length LP1 of the first pile section P1 is less than 25% of the instep length LT, the area of the pile section will be reduced, which may make blisters more likely to occur. Furthermore, since the amount of yarn used when using pile knitting increases, limiting the length LP1 of the first pile section P1 can reduce the amount of yarn used.
[0016] The pile width WP of the first pile section P1 is such that, when laid flat, the sole-side edge is located within a range of 40% to 60% of the instep-side edge of the foot width WF of the foot section 4. Preferably, the pile width WP of the first pile section P1 is such that, when laid flat, the sole-side edge is located within a range of 40% to 50% of the instep-side edge of the foot width WF of the foot section 4. In other words, the majority of the first pile section P1 is located on the instep side of the foot section 4. For example, the first pile section P1 is preferably located from the instep-side edge to the midpoint of the foot width WF. Preferably, the first pile section P1 is not located on the sole-side of the foot section 4. Pile knitting increases the amount of yarn used, so limiting the range of the pile section to areas where blisters are likely to occur reduces the amount of yarn used.
[0017] The second pile section P2 is provided around the entire circumference, covering the heel section 3, the ankle section 8, and the ankle section 9. The second pile section P2 is provided in a portion that comes into contact with the shoe opening or tongue when the shoe is worn. The second pile section P2 is provided in a range where the length LP2 from the vertex of the heel section 3 through which the gore line GL passes is between 20% and 70% of the body length LB, which is the length of the body section 6. Preferably, the second pile section P2 is provided in a range where the length LP2 from the heel section 3 is between 30% and 60% of the body length LB. More preferably, the second pile section P2 is provided in a range where the length LP2 from the heel section 3 is between 40% and 50% of the body length LB.
[0018] The first support portion S1 is a portion in which rubber is knitted all around the foot portion 4. In FIG. 1, the first support portion S1 is indicated by dots for easy identification. The first support portion S1 is provided in a region of the first pile portion P1 closer to the gore line GL. Preferably, the first support portion S1 is provided adjacent to the first pile portion P1. The length LS1 of the first support portion S1 is 5% to 45% of the instep length LT. Preferably, the length LS1 of the first support portion S1 is 15% to 35% of the instep length LT. More preferably, the length LS1 of the first support portion S1 is 20% to 30% of the instep length LT.
[0019] The second support portion S2 is a portion in which rubber is knitted around the entire circumference of the opening portion 5 of the body portion 6. In FIG. 1, the second support portion S2 is indicated by dots for easy identification. The length LS2 of the second support portion S2 is a length from the opening portion 5 of the body length LB to 20% to 40% of the body length LB. Preferably, the length LS2 of the second support portion S2 is a length from the opening portion 5 of the body length LB to 20% to 30% of the body length LB. More preferably, the length LS2 of the second support portion S2 is a length from the opening portion 5 of the body length LB to 20% of the body length LB.
[0020] (Action of this embodiment) Next, the operation of the sock 1 configured as described above will be explained with reference to Figures 1 and 2. Figure 2 shows the state in which the sock 1 is worn on a foot and a leather shoe 10 is also worn on the foot. The leather shoe 10 has a tongue 12 and is fastened with laces.
[0021] When the sock 1 is worn, the first pile section P1 is located on the instep, the first support section S1 is located on the arch of the foot, and the second pile section P2 is located in the area covering the heel, malleoli, and ankle. The second support section S2 is located above the ankle.
[0022] The first pile portion P1 is located at a lowered portion of the instep 11 of the leather shoe 10, and covers the portion that is likely to come into contact with the instep 11 of the leather shoe 10. Therefore, the first pile portion P1 reduces the impact of the instep 11 of the leather shoe 10, preventing blisters from forming due to the contact. Furthermore, because the first support portion S1 is located at the arch of the foot, it is possible to prevent the first pile portion P1 from shifting position relative to the foot, further preventing blisters from forming due to contact with the instep 11 of the leather shoe 10.
[0023] The second pile portion P2 is located in a position that makes contact with the tongue 12 of the leather shoe 10. The tongue 12 of the leather shoe 10 is located on the inside of the leather shoe 10, so it comes into frequent contact with the foot and is prone to blisters. Because the second pile portion P2 is located in a position that makes contact with the tongue 12 of the leather shoe 10, blisters can be prevented. In addition, the second pile portion P2 is located in a position that makes contact with the opening 13 of the leather shoe 10. The opening 13 of the leather shoe 10 makes line contact with the foot, so blisters are likely to occur. Because the second pile portion P2 is located in a position that makes contact with the opening 13 of the leather shoe 10, blisters caused by contact with the opening 13 of the leather shoe 10 can be prevented. In addition, because the second support portion S2 is located at the opening portion 5 of the sock 1, it is possible to prevent the second pile portion P2 from shifting position relative to the foot, further preventing blisters caused by contact with the opening 13 of the leather shoe 10.
[0024] (Effects of this embodiment) Next, the effects of this embodiment will be described. (1) The sock 1 has a first pile section P1 with a length of at least 25% of the instep length LT located in a region of the upper section 7 between 15% and 90% of the instep length LT from the toe section 2. This reduces friction with the instep 11 of the leather shoe 10 due to the first pile section P1. The first support section S1 prevents the first pile section P1 from shifting out of position, making it less likely for the first pile section P1 to shift out of areas prone to blisters. Furthermore, the second pile section P2 reduces friction between the opening 13 of the leather shoe 10 and the ankle and malleoli. This reduces the occurrence of blisters.
[0025] (2) The length LS1 of the first support portion S1 of the sock 1 is 5% to 45% of the instep length LT. This limits the area tightened by the rubber, improving comfort.
[0026] (3) The sock 1 has the second pile section P2 located in a range where the length LP2 from the apex of the heel 3 is 20% to 70% of the body length LB. Therefore, the second pile section P2 is located in the ankle section 8 and the ankle section 9, further reducing friction with the opening 13 of the leather shoe 10.
[0027] (4) The sock 1 has the first pile section P1 located in a range of 40% to 60% of the foot width WF from the instep of the foot part 4. This allows most of the first pile section P1 to be located on the instep side of the foot part 4.
[0028] (5) The sock 1 has the second pile portion P2 at a position that comes into contact with the tongue 12 of the leather shoe 10. This prevents blisters caused by friction with the tongue 12. (6) The sock 1 has a second support portion S2 provided around the entire circumference of the opening 5. This prevents the body 6 from slipping down, thereby preventing blisters caused by the body 6 being misaligned.
[0029] (7) The body length LB of the socks 1 is longer than the foot length LF. As a result, the opening portion 5 of the socks 1 is positioned higher than the opening of the leather shoes 10, and the second terry portion P2 can cover the area that comes into contact with the opening 13 of the leather shoes 10. This helps prevent blisters in business socks.
[0030] (Other embodiments) The above embodiment can be modified as follows: The above embodiment and the following modifications can be combined with each other within the scope of technical compatibility.
[0031] In the above embodiment, the body length LB, which is the length of the body portion 6, is longer than the foot length LF, which is the length of the foot portion 4. However, the body length LB may be the same as the foot length LF. Furthermore, the body length LB may be shorter than the foot length LF as long as the second pile portion P2 covers the ankles.
[0032] In the above embodiment, the second support portion S2 is provided around the entire circumference of the opening portion 5 of the body portion 6. However, the second support portion S2 may be omitted. In the above embodiment, the second pile portion P2 is positioned so as to come into contact with the tongue 12 of the leather shoe 10. However, if the user is wearing shoes without a tongue, the second pile portion P2 may be positioned so as to come into contact with the opening of the shoe.
[0033] In the above embodiment, there may be a gap between the first support portion S1 and the first pile portion P1. In the above embodiment, there may or may not be a gap between the first support portion S1 and the second pile portion P2.
[0034] In the above embodiment, the yarn used for the sock 1 was 32 count. However, the yarn used for the sock 1 may be 40 count, 60 count, or the like, which is used for business socks. [Explanation of symbols]
