For example, the engagement convex portion 51 is provided at approximately three locations on both sides and the center of the rear portion 61 of the spring receiving member 6. The engaging protrusion 51 is formed integrally with the spring receiving member 6, but is not limited to this. For example, the engaging protruding portion 51 can be projected and retracted from the spring receiving member 6 and urged in the protruding direction. May be.

  The engagement recess 52 is not particularly limited as long as the engagement protrusion 51 can be engaged to lock the lift means 3 and release the lock. For example, the engagement recess 52 is formed as a through-hole. The position of the engaging recess 52 can be selected as desired, and is, for example, two locations, the maximum lowered position and the maximum raised position of the lift member 30 of the lift means 3 with respect to the base member 2. That is, two engagement recesses 52 are provided on the rear plate 24 of the base member 2, and the lower engagement recess that is the maximum lowered position is the first engagement recess 52 a and the upper engagement recess that is the maximum raised position. Is the second engaging recess 52b. When the lift member 30 is located at the maximum ascending position, the lift member 30 cannot be moved further upward by the guide groove 26 of the guide portion 25, so that the lift member 30 moves downward. It is for locking things. In addition, when the lift member 30 can further rise from the maximum ascending position, the second engaging recess 52b prevents the lift means 3 from moving up and down. Note that the position of the engagement recess 52 is not limited to the two positions of the maximum lowered position and the maximum lift position, and in addition to these two positions, the engagement recesses may be provided at any two positions. Of course it is good.

  Next, the operation of the display device and the lifting device according to the present invention will be described.

  When adjusting the position of the display unit 12 in the vertical direction, a force is applied to the display unit 12 upward or downward. For example, when the display unit 12 and the lift member 30 are in the maximum lowered position as shown in FIGS. 1A and 3, the display unit 12 and the lift member 30 are engaged with the first engagement recess 52 a, so The upward movement is restricted and locked. The display unit 12 to which the lift member 30 is attached is lifted upward with respect to the device main body 11 by hand. As described above, when an upward force is applied to the lift member 30, the engagement convex portion 51 is released from the first engagement concave portion 52 a and the lock is released, and the spring receiving member 6 and the lift member 30 are applied to the base member 2. Move up. When the force acting on the lift member 30 is stopped, the movement of the spring receiving member 6 and the lift member 30 stops, and the display unit 12 is positioned at that position (that is, stopped at that position).

  That is, since the friction means 301 is provided on the side wall 29 that forms the guide groove 26 to which the front end 32a of the guide plate 32 of the lift member 30 is inserted and guided, the front end 32a and the side wall 29 of the guide plate 32 are provided. The movement of the spring receiving member 6 and the lift member 30 is stopped against the biasing force of the compression coil spring 41, and the display unit 12 is stopped at that position. Therefore, the display unit 12 can be stopped at an arbitrary position with respect to the device main body 11 by one simple operation of lifting the display unit 12 upward, and the operability is improved. Further, since the spring receiving member 6 is biased upward by the compression coil spring 41, the upward movement of the lift member 30 is facilitated.

  Further, when the upper edge portions of the tip portions 32a on both sides of the guide plate 32 abut on the upper edge portion 26a of the guide groove 26 (see FIGS. 1B and 4), the spring receiving member 6 and The lift member 30 does not move upward any further. At this time, as shown in FIG. 4, the engaging convex portion 51 enters and engages with the second engaging concave portion 52 b, and the upward and downward movements of the spring receiving member 6 and the lift member 30 are restricted, so The member 6 and the lift member 30 are locked at the maximum raised position. Therefore, for example, since the lock can be released, the lift member 30 can be moved, and the lift member 30 can be locked by a single simple operation of lifting the display unit 12 upward, the operability is improved.

  Next, to return the display unit 12 and the lift member 30 from, for example, the maximum ascending position to the maximum descending position, the lift member 30 is pushed downward. That is, a downward force is applied to the lift member 30. Then, the engagement convex portion 51 is released from the second engagement concave portion 52 b and the lock is released, and the spring receiving member 6 and the lift member 30 move downward with respect to the base member 2. Then, as shown in FIG. 3, the engaging convex portion 51 enters and engages with the first engaging concave portion 52 a, and the upward movement of the spring receiving member 6 and the lift member 30 is restricted, and the spring receiving member 6 and The lift member 30 is locked at the maximum lowered position, and the lift member 30 returns to the original position. Therefore, for example, since the lock can be released, the lift member 30 can be moved, and the lift member 30 can be locked by a single simple operation of pushing the display unit 12 downward, the operability is improved.

  Therefore, since the lifting device 1 according to the present invention can lift and lower the lift member 30, that is, the display unit 12 with one operation, the operability is improved, the structure is simple, and the size and cost can be reduced. It becomes possible.

  Further, the lifting device according to the present invention is provided in the toilet, and the toilet seat and the toilet lid are moved up and down with respect to the toilet body. Similarly to the above, the moving member, for example, the toilet seat and the toilet lid is lifted and lowered by one operation. This can be done on the toilet body. With this configuration, a lifting device with a simple structure and good operability can be produced, and a gap is formed between the toilet seat and toilet lid support means and the toilet body, so that it adheres to the toilet body and the support means. Thus, it is possible to easily clean dust and dirt. In this case, the lifting and lowering of the toilet seat, toilet lid, etc. is only required if the support means such as the toilet seat or toilet lid is positioned at the maximum rising position and the maximum lowering position where the toilet seat is grounded. This may be omitted from the constituting friction means.

  As described above, the lifting device according to the present invention can release the lock and move the lifting means by applying a force upward or downward to the lifting means, and the operability is improved. It is suitably used as a lifting device for toilet seats and toilet lids of devices and toilet bowls.
