Description

The present invention relates to a drawer lock mechanism repair method for repairing a drawer lock mechanism provided in a drawer in a drawer-type cabinet and fixing the position of the drawer.

In a drawer-type cabinet in which a drawer can be pulled out from the housing, a lock that locks the drawer so that it does not accidentally pop out of the housing even when the drawer-type cabinet vibrates due to an earthquake or the like. Some have a latch mechanism. The latch mechanism includes, for example, a hook-shaped latch member and a ring-shaped or concave latch receiving member that engages with the hook-shaped portion of the latch member.

A latch receiving member in such a latch mechanism is attached to the drawer so as to be rotatable around a shaft centered on a support shaft provided on the front plate or decorative plate of the drawer. The latch receiving member rotates from a position to engage with the latch member to a position to disengage from the latch member in conjunction with the operation of a lever of a pull provided on the front plate or decorative plate of the drawer. allows the drawer to be pulled out.

Further, such a latch mechanism includes a biasing member that returns the latch receiving member, which is positioned at a position for releasing engagement with the latch member, to a position for engaging with the latch member. The biasing member is implemented by, for example, a leaf spring member integrally formed with the latch receiving member.

As a related technique, specifically, conventionally, for example, a casing, a pendulum-shaped member that is freely swingable inside the casing and pivotally connected at a position above the center of gravity, and a contact on the back side a hook member having a portion formed thereon, the upper end of the hook member being pivotally connected to the opening of the casing so as to be swingable on a vertical plane substantially orthogonal to the swinging plane of the pendulum-shaped member. There is a technique related to an earthquake-resistant drawer latch in which the lower part of the pendulum-like member protrudes outward from the opening of the casing when the pendulum-like member contacts the abutted part by tilting (for example, See Patent Document 1 below.).

However, in the conventional technique described above, the leaf spring member breaks due to aging deterioration of the material forming the latch receiving member in the latch mechanism or fatigue due to repeated elastic deformation of the latch receiving member, and the drawer cannot be locked. There was a problem that it may not be possible.

Further, in the conventional technique described above, when the latch receiving member is damaged due to breakage of the leaf spring member, replacement work is performed by removing the damaged latch receiving member from the drawer and attaching a new latch receiving member. There is a problem that the cabinet cannot be used during the replacement work, which is troublesome.

In addition, in the above-described conventional technique, since the replacement of the latch receiving member is generally carried out by a specialist, the period during which the cabinet cannot be used tends to be long, which hinders business. was there.

FIG. 8 is an explanatory diagram showing a latch receiving member in a conventional drawer lock mechanism. A conventional latch receiver 121 has a rectangular frame and a plate spring member 120 formed integrally with the latch receiver 121 and the frame by, for example, injection molding. Therefore, by forming the plate spring member 120, the frame body is formed with an opening 121a. Also, the latch receiver 121 is provided so as to be able to swing around a shaft 124 as a fulcrum. The shaft 124 is, for example, inserted into an insertion hole formed to pass through the latch receiver 121 . The biasing force of the leaf spring member 120 acts on the frame via the connection position between the leaf spring member 120 and the frame. In the latch receiver 121, the biasing force of the plate spring member 120 biasing the frame body concentrates on the connecting position between the plate spring member 120 and the frame body. However, the leaf spring member 120 may be damaged or missing from the connecting position or its vicinity, that is, may be broken and separated from the frame. When the leaf spring member 120 is lost, its urging force is lost, and the later-described latch member 110 and latch receiver 121 (opening 121a) cannot be reliably engaged, and the drawer locking mechanism loses its locking function. becomes impossible.

The work of replacing the latch receiver 121 that has been damaged by the breakage of the leaf spring member 120 with a new latch receiver 121 is generally performed by a specialized trader, and can be easily replaced by the user. difficult to do. If the damaged latch receiver 121 is left as it is, the drawer may inadvertently open due to light vibration caused by a person passing around the cabinet. was likely to be lost. On the other hand, if the drawer to which the damaged latch receiver 121 is attached is fixed with adhesive tape or the like so as not to be opened in order to ensure the safety of those who pass near the cabinet, replacement becomes impossible. Until the completion, there was a problem that the cabinet could not be used and was troublesome.

In order to solve the above-mentioned problems of the prior art, the present invention reduces the burden on the operator who performs the repair work of the drawer lock mechanism, and stabilizes the position of the drawer while it is housed in the housing for a long period of time. It is an object of the present invention to provide a method for repairing a drawer lock mechanism of a drawer-type cabinet that can be fixed by

As shown in FIGS. 3, 5, 6 and 7, the latch member 110 is mounted inside the housing 310 of the drawer-type cabinet 300. As shown in FIG. Specifically, the latch member 110 is attached to the inner surface of one of the pair of side walls forming part of the housing 310 of the drawer-type cabinet 300 . The latch member 110 has a projection 111 that protrudes toward the inside of the housing 310 from the plate surface of the side wall to which the latch member 110 is attached. It is possible to reliably fix (lock) the position of the drawer 320 when it is housed in the housing 310 . Also, the latch receiver 121 lacking the leaf spring member 120 is attached to the drawer 320 in the drawer-type cabinet 300 . The configuration and operation of the drawer lock mechanism 100 by the latch member 110 and the latch receiver 121 are the same as when the latch receiver 121 is provided with the plate spring member 120 (when the plate spring member 120 is not damaged). The contents are the same as the configuration and operation of the drawer lock mechanism 100 in the prior art. 3, 5, 6, and 7, a latch structure using a latch member 110 having a protrusion 111 and a latch receiver 121 (how to lock and how to lock the locked state). The structure for holding and releasing the locked state), including the shape of the projection 111, can be realized using well-known techniques.

Elastic member 122 is attached to drawer 320 in pull-out cabinet 300 . The elastic member 122 is attached to the outer surface of one of the pair of side plates forming part of the drawer 320, the side plate facing the side wall to which the latch member 110 is attached. The elastic member 122 is arranged on the side opposite to the latch member 110 with the latch receiver 121 therebetween. The elastic member 122 has a flat rectangular parallelepiped shape. The elastic member 122 is made of an elastic material that deforms in response to an applied external force and returns to its original shape when released from the external force. The elastic member 122 urges the latch receiver 121 from the unlocked position side to the locked position side by its own elastic force. Regardless of the position of the drawer 320 with respect to the housing 310 , the latch receiver 121 is always urged from the unlocked position side to the locked position side by being urged by the elastic member 122 . The elastic member 122 can be made of a material such as urethane, silicon, rubber, or the like. The elastic member 122 is preferably realized by a porous structure made of flexible material called sponge. More specifically, the elastic member 122 is realized by a sponge formed by foaming and molding a material such as urethane, polyethylene, polyether, EVA (Ethylene-Vinyl Acetate Copolymer), melamine, or the like. is preferred. A sponge can be obtained inexpensively and easily.

The elastic member 122 can be attached to the drawer 320 using a magnetic sheet 125, for example. When the side plates of the drawer 320 are made of a material such as an iron plate that attracts a magnet, the use of the magnet sheet 125 allows the elastic member 122 to be attached to the drawer 320 easily and quickly. Another magnet sheet to which the magnet sheet 125 is attached may be attached to the drawer 320 of the drawer-type cabinet 300 . Thereby, the elastic member 122 can be attached to the drawer 320 using the magnet sheet 125 regardless of the material of the drawer 320 . Further, when exchanging the elastic member 122, the exchanging work can be performed easily and quickly. The elastic member 122 may be attached to the drawer 320 using, for example, adhesive tape.

5, 6 and 7, the front plate 323 is provided along the front side of the four peripheral sides of the bottom plate 321 . As shown in FIG. 5, when the drawer 320 is accommodated in the housing 310, the drawer lock mechanism 100 engages the projection 111 of the latch member 110 with the opening 121a of the latch receiver 121. The position of the drawer 320 is fixed (locked) while the drawer 320 is accommodated in the housing 310 . Since the latch receiver 121 is urged from the non-locked position side to the locked position side by the elastic member 122, the position of the drawer 320 can be adjusted to the drawer 320 while the user does not operate the handle 326 to position the drawer 320 at the drawn-out position. can be reliably fixed (locked) in a state in which is housed in the housing 310 .

When opening the drawer 320, the user puts his or her finger on the handle 326 and pulls the finger forward, as shown in FIGS. As a result, as shown in FIG. 6, the handle 326 swings from the rest position to the drawn position, and in conjunction with the swinging of the handle 326, the latch receiver 121 resists the biasing force of the elastic member 122 and moves to the lock position. to the unlocked position with the shaft 124 as a fulcrum, and the lock by the drawer lock mechanism 100 is released. In this manner, the user of the drawer-type cabinet 300 simply pulls the handle 326 with his/her finger to pull out the drawer 320, thereby positioning the handle 326 in the drawn position and positioning the latch receiver 121 in the unlocked position. , the lock of the drawer 320 by the drawer locking mechanism 100 can be released.

When the user further pulls the finger on the handle 326, the drawer 320 can be pulled out while the frame is positioned at the unlocked position, that is, in the unlocked state. When the user releases the handle 326, the frame is biased by the biasing force of the elastic member 122 and positioned at the locked position, as shown in FIG. The handle 326 is positioned at a stationary position in conjunction with swinging with the shaft 124 of the latch receiver 121 as a fulcrum.

When closing the drawer 320 , the latch receiver 121 passes over the protrusion 111 of the latch member 110 . At that time, it swings around the shaft 124 so as to avoid the protrusion 111 against the biasing force of the elastic member 122, and after passing the protrusion 111, as shown in FIG. to be positioned in the locked position. As a result, the user can fix the position of the drawer 320 by the drawer lock mechanism 100 simply by pushing the drawer 320 into the housing 310 without operating the handle. Thus, the elastic member 122 allows the latch receiver 121 to perform the same operation as when the plate spring member 120 is provided.

As described above, the drawer lock mechanism repair method according to the embodiment of the present invention is provided in the drawer 320 of the drawer-type cabinet 300, and when repairing the drawer lock mechanism 100 that fixes the position of the drawer 320, the latch member An elastic member 122 separate from the latch receiver 121 is used to urge the broken or missing latch receiver 121 to the latch member 110 side. By arranging the latch receiver 121 on the side opposite to the latch member 110 side, the drawer lock mechanism 100 can be repaired. Specifically, for example, the latch receiver 120 is provided on the drawer 320 in the drawer-type cabinet 300, and the protrusion 111 protruding from the side of the housing 310 that accommodates the drawer 320 in a drawable manner toward the drawer 320 and the drawer 320 A latch receiver 120 of a drawer locking mechanism 100 that fixes the position of a drawer 320 by being engaged in a state housed in a housing 310, wherein the locking position engageable with the projection 111 and the projection 111 A latch receiver 121 that can swing between an unlocked position and an unlocked position, and the latch receiver 121 are separate members that urge the latch receiver 121 from the unlocked position side to the locked position side. and an elastic member 122 that Further, the drawer lock mechanism 100 of the drawer-type cabinet 300 is provided in the housing 310 that accommodates the drawer 320 in the drawer-type cabinet 300 so as to be able to be pulled out, and has a projection 111 projecting from the housing 310 side to the drawer 320 side. The latch member 110 and the drawer 320 are swingable between a locking position in which the projection 111 can be engaged when the drawer 320 is accommodated in the housing 310, and an unlocking position in which the engagement with the projection 111 is released. It comprises a latch receiver 121 attached to the drawer 320 and an elastic member 122 which is separate from the latch receiver 121 and biases the latch receiver 121 from the unlocked position side to the locked position side. Therefore, the latch receiver 121 and the elastic member 122 are separate members, and the latch receiver 121 and the elastic member 122 can be replaced independently. As a result, only the elastic member 122, which is more likely to be damaged or deteriorated due to deterioration than the latch receiver 121, can be used as the latch receiver, without changing the latch receiver 121, which is less likely to be damaged and takes time to replace. The tool 121 can be easily replaced regardless of the life of the tool 121, and the burden on the operator who performs work related to maintaining the function of fixing the drawer 320 by the drawer lock mechanism 100 is reduced. The position of the drawer 320 in can be stably fixed over a long period of time.

In addition, by urging the latch receiver 121 from the non-locked position side to the locked position side by the elastic force of the elastic member 122 itself, only by positioning the elastic member 122 between the drawer 320 and the latch receiver 121, a special The elastic member 122 can be easily attached to a proper position and the latch receiver 121 can be urged from the unlocked position side to the locked position side without requiring a special skill or experience. As a result, the burden on the operator for maintaining the function of fixing the drawer 320 by the drawer lock mechanism 100 can be reduced, and the position of the drawer 320 can be stably fixed over a long period of time when it is accommodated in the housing 310. can.

In addition, since the elastic member 122 is a porous structure made of a flexible material, the elastic member 122 can be made of a porous structure made of a flexible material. The receiver 121 can be biased from the unlocked position to the locked position. By realizing the elastic member 122 with a structure called a so-called sponge, the elastic member 122 is urged according to the shape of the latch receiver 121 while urging the latch receiver 121 from the unlocked position side to the locked position side. can be easily transformed. As a result, regardless of the shape of the latch receiver 121 , the latch receiver 121 can be reliably engaged with the latch member 110 , and the drawer lock mechanism 100 can fix the position of the drawer 320 . In addition, since the elastic member 122 can be easily deformed according to the shape of the latch receiver 121, even if the mounting position of the elastic member 122 is shifted, it will not interfere with surrounding members and damage the surrounding members. do not have. As a result, it is possible to improve the convenience of the operator involved in maintaining the function of fixing the drawer 320 by the drawer lock mechanism 100 and the user of the drawer-type cabinet 300 .

In addition, since the elastic member 122 is attached to the drawer 320 using the adhesive tape or the magnet sheet 125, the drawer 320 is not processed, and the function of fixing the drawer 320 by the drawer lock mechanism 100 can be maintained.
